Buffer variable force energy adsorption adjustable device for preventing vehicle from running in inclined shaft

Abstract

The invention discloses a buffer variable force energy adsorption adjustable device for preventing a vehicle from running in an inclined shaft and relates to mining equipment. The device consists of a vehicle stopping column 6 for preventing a mining vehicle from running, and a variable force energy adsorption device 9. The vehicle stopping column 6 comprises a plurality of buffer steel wire ropes 8, C-shaped sleeve pipes 6-1, and hanging chains 6-2; two ends of each buffer steel wire rope 8 are connected with the viable force energy adsorption device 9; the C-shaped sleeve pipes are connected through the hanging chains 6-2 to form a grating guardrail; and the hanging chains 6-2 are connected with a lifting winch 4. The variable force energy adsorption device 9 is arranged on an inclined shaft basis through foundations 10 and foundation bolts 16 and comprises a support 9-1, a shaft 9-4, a shaft sleeve 9-6, a winding drum 9-8, an external brake plate 9-10, an inner brake plate 9-12, and a friction sheet 9-13. The device performs adjustment timely and buffers energy according to parameters of each inclined shaft, so that the device can effectively stop the vehicle optimally when the rope is broken and then the vehicle runs in the inclined shaft; therefore, the deformation of the mine vehicle under impact is reduced.

Description

technical field [0001] The invention relates to a mining equipment, in particular to a safety device for buffering and absorbing energy of the mine car used in inclined lane transportation to prevent the mine car from running. Background technique [0002] At present, there are three main types of anti-car equipment transported in inclined lanes of coal mines: one is relatively simple and low-cost equipment, which is welded into the shape of a fence gate by steel pipes or I-beams and other materials, and two vertical shafts are installed on one side of the fence gate , shaft sleeves, assembled, and the assembled fence gate is installed at the lower opening of the inclined roadway. When the rope breaks in the inclined lane, the worker pulls the rope to close the fence gate, and intercepts the broken rope. Although it plays a certain role in safety, it needs to be activated manually to produce action, the interception effect is not good, and it does not have cushioning perform...

AI Technical Summary

Problems solved by technology

[0004] 1. Infrared detection equipment is prone to malfunction and cause accidents;

[0005] 2. The reliability of the single-chip microcomputer is not high, and its buffer device is a linear pressure plate type buffer, the buffer force cannot be reliably calibrated, and the buffer performance is poor

The decentralization of the interception net is sent to the programmable controller through the signals detected by two kinds of sensors for judgment, identification and sound and light alarm.
