Embodiment Construction

[0014] The present invention will be further described below in conjunction with the embodiment in the accompanying drawings:

[0015] figure 1 As shown, the friction lifting anti-skid experimental device is composed of a frame 1, a power device 2, a guide device 3, a tension adjustment device 4, a brake device, a loading device 9, 11, and a detection and control device. The frame 1 is welded or riveted by section steel and steel plate to form a derrick type rigid structure, and other devices are all fixed on it according to certain space requirements. Loading devices 9, 11 are containers with different weights that can be added. Loading devices 9, 11 are hung on the friction wheel 2-3 of power unit 2 through steel wire rope 5. Loading devices 9, 11 and steel wire rope 5 are connected. Tension sensors 7, 13 and acceleration sensors 8, 12 connected with the control device. The braking device mainly brakes the power unit 2. It consists of a brake disc 14 on the same shaft as t...

Abstract

A multi-functional friction lift anti-skid experiment device and method is composed of a frame, a power device, a guide device, a tension adjustment device, a braking device, a loading device, and a detection and control device. The power device drives the loading device to lift and lower through the wire rope, simulating the operating conditions of mine friction lifting. The brake device and the power device are on the same shaft, and the brake device brakes the power device. The guiding device can change the size of the wrapping angle of the friction wheel in the power unit. The tension adjusting device clamps the wire rope to reduce the tension difference of the wire rope on both sides of the friction wheel in the power unit. Shaft encoders are installed on the power device and guiding device, and tension sensors and acceleration sensors are installed on the loading device. The detection and control device judges the lifting state by receiving the sensor value and predicts the sliding rope. Once the signs of slippage are judged, the power unit, guide device and tension adjustment device are controlled to prevent and eliminate slippage.

Description

technical field [0001] The invention relates to a multifunctional friction lift anti-slip experiment device and method, and is especially suitable for a sliding rope experiment simulating the operating condition of a mine friction hoist, researching the friction lifting sliding rope mechanism and a method for detecting and eliminating sliding. Background technique [0002] Friction hoists have been widely used in mine hoisting systems. Article 433 of my country's "Coal Mine Safety Regulations" stipulates that under various loads and hoisting conditions, when the safety gate is activated, the wire rope must not slip. However, the friction hoist has the danger of slipping the hoisting wire rope and the friction wheel in the above state, which involves the safety of mine workers, so the slipping of the hoisting wire rope and the friction wheel is an urgent problem to be solved in friction hoisting. At present, there is no effective method at home and abroad to solve the problem...
