Embodiment Construction

[0056] The present invention will be described in detail below in conjunction with specific embodiments.

[0057] Such as Figure 1-6 As shown, a steel wire rope and friction lining comprehensive friction detection device for a hoist is used to simulate the cross contact continuous high-speed sliding friction between steel wire rope and steel wire rope Pad continuous high-speed sliding friction working conditions, and detect the relevant friction and wear parameters under each working condition. The device includes a base frame, a steel wire rope placed on the Continuous creeping friction and wear system and steel wire rope and friction lining continuous high-speed sliding friction system.

[0058] The power source drives the active friction wheel 04 to rotate to drive the jointless steel wire rope 13 to move at high speed. At this time, the test device can simulate the continuous high-speed sliding friction between the steel wire rope and the cross contact between the steel ...

Abstract

The invention discloses a device and a method for comprehensively detecting the friction between steel wire ropes and friction liners of a hoist. The device comprises a base frame, a system for continuous sliding friction continuous high-speed sliding friction between the steel wire ropes by virtue of cross contact, a system for continuous creeping friction and wear between the steel wire ropes by virtue of cross contact and a system for continuous high-speed sliding friction between the steel wire ropes and the friction liners, wherein the three systems are arranged on the base frame. By adopting the device and the method, the characteristic of friction between the steel wire ropes of the winding hoist and the characteristic of high-speed sliding friction between the steel wire ropes and the friction liners can be detected, and the high-speed sliding friction between the steel wire ropes by virtue of cross contact, the creeping friction and wear between the steel wire ropes by virtue of cross contact and the high-speed sliding friction between the steel wire ropes and the friction liners can be simulated.

Description

technical field [0001] The patent of the present invention relates to a comprehensive friction detection device and method for a steel wire rope and a friction lining for a hoist. Background technique [0002] The mining depth of the mine is continuously increasing. The friction mine hoist has unique advantages in lifting capacity, lifting height and lifting speed. In addition, it has the advantages of high safety factor and small structure size, so it is more and more used in mine hoisting. However, when the lifting depth exceeds 1600m, the friction hoist can no longer meet the required requirements, and a winding hoist needs to be used instead. The hoisting wire rope and friction lining are important components to ensure the normal operation of the friction hoist. The friction between the wire rope and the friction lining determines the lifting capacity of the friction hoist. In the winding hoist, the wire rope and the wire rope cannot To avoid various contact friction be...
