A buffer iron shoe set is added at 1.5 meters at the front of the hydraulic sliding block. When the vehicle approaches the vehicle stopper, the wheels first contact the iron shoe group to buffer and reduce speed, and then the coupler impacts the vehicle stopper buffer spring to dampen the vibration, both to dampen the vehicle and reduce the impact of the vehicle. The shoe set automatically returns to its original position.In hydraulic slide 1.5 meters of the front-end buffer stops additional buffer iron group a set of shoes. Close to the car stop when the car, the wheels first contact with the iron shoes groups buffer speed down, and then coupling vibration and shock buffering spring buffer stops play, both plays damping buffer and reduce vehicle for intense collision, when the vehicle back cushion iron shoes set auto reply in situ.
An anti-shock damping spring is installed on the head of the hydraulic sliding car stopper. When a locomotive vehicle coupler hits the head spring of the car stopper to reduce the vibration and reduce the impact force, the gravity acceleration is reduced, and the car stopper's ability to stop and the car's impact displacement are greatly improved , To extend the service life of the car stopper.Hydraulic sliding kick in the head to install shock damping spring, when the rolling stock under coupling impact head spring vibration drop impact, reduce the acceleration of gravity, greatly improving the buffer capacity for car stop and the car stop by ramming displacement, prolong the service life of the car stop.
Reflective signs and light-controlled red signal lights are installed on the upper part of the hydraulic sliding car stopper. The signs are very eye-catching during the day and night.Hydraulic sliding under the upper installation of reflective signs and relating to red lights, day and night logo is very eye-catching.
There are four sets of auxiliary vehicle stoppers, two for each rail.Auxiliary car stop for the four groups, each rail in the two groups.
The structure is compact and the force is reasonable. The main frame adopts a quadrangular pyramid frame structure. The upper cross beam is eliminated, the bottom is a cross, and a buffer device is added. Each component is hinged and bolted to facilitate component handling, assembly, and disassembly.
Adopting elastic pressurization, the main body frame and two pairs of dampers have damping devices. You can adjust the contact pressure between the friction seat and the basic rail by rotating the compression screw. When the vehicle and the stopper are sliding, they will slide. Relying on the force of the spring to maintain a stable friction, it will not cause seizure due to excessive friction.
The main frame and the two pairs of dampers have a certain distance from each other, and can gradually increase the friction of the work in three stages in order, gradually reducing the peak value of the collision energy, and improving the stability of the vehicle. Compared with foreign “sliding type stoppers”, it has the outstanding advantages of simplified structure, reasonable force, elimination of beams, elastic compression, braking performance, cushioning performance and maximum allowable impact speed.

First remove the four outer brake rails in the left and right brake rail assemblies, and take out the spring seat plate and friction block; place the two spring spring seats in the plane direction respectively to the left and right brake rail On the basic rail surface below the position of the pressure bolt, two spring plates are stacked in the upper grooves with the convex surfaces facing upward. The friction block is placed on the base rail surface which is predetermined as the position of the rear support. The brake rail assembly from which the outer rail has been removed is distinguished from the front and rear positions (the end with the pressure bolt on the support is front), and is installed from the inside of the basic rail. During installation, the bracket is on the top, and the brake rail is on the bottom to clamp the basic rail.
Put the outer brake rails on the front and rear with bolts, adjust the positions of the spring seats and friction blocks so that they are placed between the two hexagonal bolts in the horizontal direction, with the hexagonal bolts; use four cross beams and cross beams to attach the four brake rails. For the connection of the support, refer to the structure diagram for the overlap form. The middle of the two inclined beams cross the long cross pin and are separated by the cross washer, and the four corners are connected by the four cross short pins.
Insert the lower end of the left and right arm (there is a hole end) into the front support chute of the corresponding brake rail, and connect them with the big pin of the arm. Raise the buffer support assembly. With the rubber side facing down, move the upper end of the front arm into the chute of the buffer support. The two holes of the arm are aligned with the two holes of the chute. They are connected by the big pin of the arm. The plane of the two front arms is perpendicular to the ground plane.
After the above initial installation is completed, tighten the bolts, and finally tighten the pressure bolts. Use the plug gauge or a special measuring gauge to detect the bending between the spring onboard pressure bolts and the spring seat by using the plug gauge or a special detection gauge from the outer middle of the brake rail. The gap is 0.5-0.6mm.
Remove the damper brake rail assembly from one side of the brake steel rail, and take out the spring seat and spring plate. Put the spring plate on the basic rail at the rear of the main frame, put the spring plate on the convex side, place the brake rail on the spring seat, clamp the basic rail with two brake rails, and put bolts. Adjust the spring seat and damper. Each pair of dampers is parallel to each other, the first pair is 100 ± 2mm from the main body frame, and the second pair is 80 ± 2mm from the first pair. Then tighten each bolt, finally tighten the pressure bolt, and test the gap between the spring plate and the spring seat while tightening, reaching 0.5-0.6mm.
In order to obtain greater braking capacity and higher impact speed, the hydraulic sliding car block adds a hydraulic buffer cylinder between the buffer head and the main body frame.
Hydraulic buffer cylinder is divided into single-section and multi-section.
In order to get more braking ability and higher impact velocity, hydraulic sliding kick in the head and body frame buffer
added between the hydraulic buffer cylinder. Hydraulic oil cylinder buffer is
divided into single section type and multiple class type.
In a single-section hydraulic buffer cylinder, 3/4 of the cylinder volume is hydraulic oil, and the remaining space is air. Because the gas is highly compressible, it can act as a buffer when the vehicle contacts the buffer head. In a multi-section plunger cylinder, the cylinder is completely filled with hydraulic oil. The main role of the small-caliber oil cylinder is to cushion and also have a certain braking force. The function of the large-caliber oil cylinder is to increase the braking force. Adjust the opening pressure of the relief valve to change the braking force of the cylinder.
Before the vehicle does not hit the hydraulic sliding gear, the oil cylinder is in an extended state under the action of the return spring. When the vehicle is hit by the vehicle, the vehicle coupler comes into contact with the buffer rubber plate at the front of the stopper plunger, and the vehicle ’s kinetic energy is transmitted through the buffer rubber plate. The plunger plunger is retracted into the cylinder under the action of the external force, which converts the external force into system pressure When the system pressure exceeds the preset safety valve opening pressure, the safety valve opens automatically. The hydraulic oil in the cylinder flows to the tank through the safety valve.
According to the principle of the hydraulic system, when hydraulic oil passes through small holes and gaps, it must generate a pressure drop and perform work and heat. The hydraulic system converts the vehicle's kinetic energy into thermal energy, which causes the oil temperature to rise, and then radiates the heat slowly into the air. When the vehicle's kinetic energy is greater than the kinetic energy consumed by the hydraulic cylinder, the remaining kinetic energy of the vehicle drives the body of the stopper to continue to slide along the rails. Sustainedly maintain a strong friction resistance between the friction seat and the rail surface and the lower jaw of the rail and the damper housing, so as to absorb the remaining vehicle kinetic energy and stop the vehicle.
Car stops should always be in good condition. In daily use, you should pay attention to clearing obstacles in the sliding range of the vehicle stopper, and handle the super high-speed studs or sleeper bolts.
It is checked thoroughly every month. Abnormal conditions such as displacement, deformation, loose fasteners, and missing parts should be found and should be handled in a timely manner.
After the car stopper is displaced by impact, first use a hand hammer to knock out the wedge pin and check whether all parts are damaged. If damage is found, it should be repaired or replaced. Pull the car stopper back to its original position, adjust the distance between each booster, and tighten the bolts, nuts and other fasteners.
Turn the spring plate in the booster up and down once a year, apply anti-rust paint every 2 years, and replace the spring plate every 4 years.
The hydraulic buffer car for rails is replenished with hydraulic oil every two quarters, and the hydraulic oil is replaced every 4 years. When replacing the hydraulic oil, check the seals. If the seals are significantly aged or deformed, they need to be replaced in time.
The car stopper is supplied in the form of an assembly. The fasteners of the assembly before leaving the factory must be fastened according to the location of the parts, and then tied with a wire to make it strong and firm. Before installation, you should complete the inventory according to the components provided below, and then install it on site.
