Description

Technical Field

[0001] The utility model belongs to the technical field of mining equipment and relates to a clamp for quickly disassembling a brushless and ringless starter. Background Art

[0002] The crushing system of metal mines is a key production process underground. The main method of driving the crushing station is to use a high-voltage asynchronous motor to drive the pulley to drive the crushing cone to complete the process of ore crushing. Its working conditions require that the motor has a high power factor and a large starting torque when starting. A brushless ringless starter is often used to connect with the motor to achieve low-speed and high-torque starting. Due to the single design system in the early stage of the mine underground and the gradual increase in the amount of tasks it undertakes, the motor is overloaded, resulting in failure of the brushless ringless starter. After the brushless ringless starter is damaged, the maintenance personnel need to remove the main motor, pull it to the surface, and send it to the manufacturer for repair. It is time-consuming and laborious to replace it quickly. Limited by the conditions underground in the mine, the problems caused by on-site replacement are as follows: (1) The installation gap between the brushless ringless starter and the main motor is too small, and the professional hydraulic puller disassembly tool cannot be stuck in it, making it difficult to disassemble; (2) When an emergency occurs in the underground, the brushless ringless starter of the main motor cannot be replaced immediately due to the lack of suitable disassembly tools, which reduces the maintenance efficiency of the equipment and seriously affects the normal operation of the crushing system. Utility Model Content

[0003] The purpose of the utility model is to provide a clamp for quickly disassembling a brushless ringless starter in response to the problems existing in the prior art, thereby solving the problem that the starter is difficult to disassemble due to the small installation gap between the existing brushless ringless starter and the main motor and the lack of suitable disassembly tools, which affects the normal operation of the crushing system.

[0005] A clamp for quickly disassembling a brushless ringless starter, comprising a first positioning clamp and a second positioning clamp which are symmetrically arranged, and the two are connected by a plurality of adjusting screws, the first positioning clamp is square in shape, and is provided with a plurality of first positioning holes, there are three first positioning holes in total, and the three are arranged in a triangle, the second positioning clamp is also square in shape, and a U-shaped groove is provided at the bottom, the second positioning clamp is provided with a plurality of second positioning holes, and the second positioning holes are arranged correspondingly to the first positioning holes, a jack, a supporting steel sleeve and a brushless ringless starter are arranged in sequence between the first positioning clamp and the second positioning clamp, a motor is provided on the other side of the second positioning clamp, and the brushless ringless starter is provided with a transmission shaft, which is connected to the motor after passing through the second positioning clamp.

[0006] Furthermore, a force rod is provided on the side wall of the jack.

[0007] Furthermore, a plurality of adjusting nuts are provided at the connection points between the first positioning clamping plate, the second positioning clamping plate and the adjusting screw.

[0008] The beneficial effects of the utility model are:

[0009] During use, the utility model utilizes the cooperation of the first positioning clamp plate and the second positioning clamp plate to quickly dismantle the brushless ringless starter. After the spacing between the two positioning clamp plates is adjusted by adjusting the lead screw and the adjusting nut, the two positioning clamp plates are fixed and disassembled, which can greatly reduce the work intensity of maintenance personnel and improve maintenance efficiency.
