Embodiment Construction
[0014] The specific embodiment of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0015] A deceleration energy absorber for mine car derailment prevention in underground mines, including an outer cylinder, a square shaft located in the outer cylinder, and a steel cable wound on the square shaft, and the square shaft is also fixed with multiple layers parallel to the cross section of the square shaft. As for the movable friction plate, multiple layers of fixed friction plates parallel to the movable friction plate are fixed on the inner wall of the outer cylinder, and the movable friction plates and the stationary friction plates are stacked alternately.
[0016] Preferably, a tensioning friction plate is sandwiched between the movable friction plate and the stationary friction plate.
[0017] Further, the tension friction plate material is asbestos.
[0018] Preferably, a compression spring is also included, and...

The invention discloses a deceleration energy absorber used for preventing a mine underground mine car from derailing. The deceleration energy absorber comprises an outer barrel, a square shaft and a wire rope, wherein the square shaft is positioned in the outer barrel; the wire rope is wound on the square shaft; the square shaft is also fixedly provided with multiple layers of movable friction plates in parallel with the cross section of the square shaft; the inner wall of the outer barrel is also fixedly provided with multiple layers of stationary friction plates parallel with the movable friction plates; the movable friction plates and the stationary friction plates are alternately stacked. Practice proves that the deceleration energy absorber used for preventing the mine underground mine car from derailing has the advantages of safety, reliability, convenience in use and maintenance, long service life and stable performance, is worthy of further popularizing and is installed and used in multiple mines.
Description
technical field [0001] The invention belongs to the field of machinery, and relates to a deceleration energy absorber for preventing derailment of mine vehicles in mines. Background technique [0002] Due to the lack of prevention and supervision measures for underground gas explosion accidents, before 2000, tens of thousands of people died in coal mine safety accidents in China every year. Accidents have been prevented in advance, greatly reducing the accident rate caused by gas explosions. [0003] But for another type of underground common accident, mine car derailment accident has never attracted people's attention. In fact, fatal accidents due to mine car derailment occur every year, often causing death or serious injury and disability. [0004] In the existing underground safety equipment, although there are monitoring probes and first aid facilities for the derailment of the mine car, there is no technical facility for how to control the speed of the derailed mine ca...
