Embodiment Construction

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

[0015] As shown in Figure 1, the friction lifting and anti-slip experimental device is composed of a frame 1, a power device 2, a guiding device 3, a tension adjusting device 4, a braking device, loading devices 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 sh...

Abstract

The invention provides a multifunctional friction lifting anti-slip experimental device and a method. The experimental device is composed of a frame, a drive device, a guide device, a tension adjusting device, a brake device, a loading device and a detection and control device. The drive device can drive the loading device to make lifting and lowering movement through a wire rope, thus simulating the friction lifting operation condition of mines. The brake device is disposed on the same shaft with the drive device for braking the drive device. The guide device can change the magnitude of a wrap angle of a friction wheel in the drive device. The tension adjusting device is used for clamping the wire rope to reduce the tension difference of wire ropes on both sides of the friction wheel in the drive device. A shaft coder is provided on the drive device and the guide device, a tension sensor and an acceleration sensor are provided on the loading device, and the detection and control device is used for determining the lifting state by receiving the values of the sensors to predict sliding rope and for controlling the drive device, the guide device and the tension adjusting device to act once a sliding sign occurs, thus preventing and eliminating 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...
