What can I do if the large machinery can't get in?

Rake mine winch for your share

Rake mine winches are mainly used for ore handling and filling in the pits or open pits of metal mines and other mines. It is mainly used for horizontal raking and can also be used for slope raking with small inclination. It cannot be used as lifting equipment. The driver can operate by hand beside the winch, and can also perform distance control with a button at a distance of several meters to dozens of meters away from the winch.

Product introduction

Rake mine winches are mainly used for ore handling and filling in the pits or open pits of metal mines and other mines. It is mainly used for horizontal raking and can also be used for slope raking with small inclination. It cannot be used as lifting equipment. The driver can operate by hand beside the winch, and can also perform distance control with a button at a distance of several meters to dozens of meters away from the winch.

The rake mine winch is driven by a steel wire rope wound on a drum to make a reciprocating movement to haul materials.

Motor

Mine winch

Rake mine winch

The motor is a flame-proof three-phase asynchronous motor, which is a basic series of fully enclosed, self-fan-cooled, squirrel-cage, and flame-proof three-phase asynchronous motors. And it has the characteristics of excellent performance, safe and reliable use, lower vibration and noise than similar products, and meets environmental protection requirements. Suitable for places where explosive gas mixtures exist in petroleum, chemical, mining, metallurgy, power and other industries. Is the ideal power equipment.

Reduction gear
Reducer

Mine winch

Rake mine winch

The mine winch reducer is all herringbone gear structure, which can make the rotation process more balanced, and also improve the machine's transport capacity and stability! In addition, it also has low noise, winch reducer, and pumping reducer JSZ type double force line center drive reducer. The high-speed shaft and low-speed shaft are on the same straight line, so that the main motor, reducer, and spindle device are "one" Word layout, compact structure reduces the area of the machine room, easy installation and maintenance. The reducer has a herringbone structure. In addition to the characteristics of a helical gear, it can also balance the axial force generated during the rotation. Further improved the carrying capacity and stability. The intermediate gear adopts elastic gear, which has low noise and vibration and strong impact resistance.

Rake mine winch

The three-drum winch has one main reel (installed in the middle) and two auxiliary reels (installed on the left and right). The three-drum winch can also install two main reels (installed on the right and middle) and one auxiliary Drums (installed on the left), each drum has a control device and a rope guide.

的安装 Installation of harrow mine winch installation

Rake mine winch installation

Due to the frequent relocation in the field use of rake mine winches, the permanent concrete foundation is usually not poured. Practice has proved that the quality of the temporary installation will directly affect the use efficiency and life of the winch. In this regard, the user department must not be taken lightly. At present, the temporary installation methods commonly used can be summarized as follows. First, when the roof of the stope is low, it is easy to fix the winch with wooden pillars. Second, when the roof of the stope is high, wooden pillars are still used. Although it is unsafe. To this end, a wire rope can be used to tighten the back of the winch base to fix it. But both methods have disadvantages. The former is limited by the height of the top plate. The latter has two problems that are difficult to overcome: a. If the mineral deposits in front of the winch are high or the position of the guide pulley is too high, the winch will cause a jump during use and damage the equipment. b. The base is easily damaged by the wire rope. For reasons of appeal, a screw-pillar fixation method may be considered.

的故障和检修 Failure and maintenance of raking winch Overhaul

Failure and overhaul

Rake mine winches are relatively simple and reliable equipment, and there are usually few operating failures, but sometimes some problems occur. For example, the brake band is broken, the motor seat is cracked, the motor is rotating and the drum cannot be wound around the wire rope.

The break of the brake band and the crack of the motor seat are caused by overload. During the work of the electric harrow winch, the rake bucket sometimes encounters excessive resistance and it is difficult to advance. At this time, the rake bucket should be moved back a distance and then continue to rake. Do not pull hard to avoid damage to the electric rake equipment and Personal accident.

The brake belt of the winch is made of 2 mm thick steel plate and 8 mm thick asbestos plate. Because the brake tape is wound around the drum, when the rotating drum is braked, the elastic deformation varies greatly and the stress state is different. According to analysis and practice, it is most likely that the place close to the inside of the brake tape will break. After repeated innovation tests in several units, the heavy cast brake head was removed, and the brake band was divided into three sections and hinged with small shafts. In this way, the elastic deformation of each section of the brake band is relatively uniform, and it has a self-adjusting effect on the brake tightness of the brake wheel, which can extend the life of the brake band by more than five times.

The inflexible operation of the brake is caused by the improper adjustment of the lever and spring of the brake lever, or the presence of oil and dust on the brake rim, which greatly reduces the friction. In this case, you must adjust the lever and spring of the brake lever in time, control the gap between the brake band and the brake rim, and make the brake stroke of the brake lever within the range of 200-300 mm.

When it is found that the motor is rotating and the drum cannot be wound around the wire rope, the motor shaft head may be broken, or the pinion gear may be damaged, or the planet gear or the bracket may be damaged. At this time, the reducer must be opened for inspection and repair, and the damaged and unrepairable parts must be replaced in time.

Before overhauling the rake mine winch, it is necessary to grasp the cause and length of the fault during use. Generally speaking, the brake belt should be replaced when the wear reaches 2 mm; the transmission gear of the reduction mechanism should be replaced when the wear reaches 1 mm; it is best to replace the meshing gears at the same time during maintenance, even if the meshing gears are not worn yet To the extent that it cannot be used, it should be replaced accordingly to avoid noise and impact during transmission.

Work site, electric harrow winch should be checked once a week. Mainly make a careful external inspection of each part: check the reel and brake action; check the status of the wire rope and guide rollers; check whether the winch frame is firmly fixed, and if necessary, open the casing to check the gear meshing and bearing coordination And lubrication, find problems, and repair in time.
