Explosion proof type vehicle running prevention blocking device based on energy conversion

Abstract

The invention discloses an explosion proof type vehicle running prevention blocking device based on energy conversion. The device comprises a fixed base and an arresting cable device arranged on the fixed base; a brake steel wire rope on the arresting cable device is connected with a vehicle, and when the vehicle speed is out of control, emergency brake is provided; an explosion proof type energyabsorbing device is arranged in the arresting cable device, and through the explosion proof type energy absorbing device, kinetic energy of the vehicle can be converted into internal energy. The blocking device can be applied to various vehicles under the coal mine, the stable blocking brake force is provided for the vehicles with speed out of control, the phenomenon that the speed of the vehiclesunder the coal mine is out of control is effectively avoided, the reasonable protection measure is provided for out-out-control speed of the vehicles under the coal mine, the coal transportation vehicle safety situation is optimized, the vehicle safety property is improved, operation safety coefficient of the vehicles is improved, and the mine system safety is improved.

Description

technical field [0001] The invention belongs to the technical field of coal mine machinery and equipment, and in particular relates to an explosion-proof anti-sports car blocking device based on energy conversion. Background technique [0002] When the speed of the vehicle is out of control on a slope or in an alley, the tail hook installed on the out-of-control vehicle hooks the arresting cable wound on the arresting device. At this time, the arresting device can output resistance, and the kinetic energy and potential energy of the vehicle are absorbed by the arresting device, making the vehicle Slow down, brake, and finally stop. [0003] The prevention and protection measures for the out-of-control speed of explosion-proof vehicles in underground coal mines: [0004] 1. Set waste tires on the side of the ramp or at the bottom of the ramp as buffers to prevent vehicles from scratching and rigidly colliding with the side walls of the roadway. This mode causes great damage...

Therefore, when used in coal mines, there is a very large potential safety hazard

[0009] The Chinese patent No. CN201711045107.8 is a braking type energy absorber with initial buffer function and a rubber-tyred vehicle anti-running method. In the above-mentioned patent, the entire energy absorber is exposed in the underground roadway without any explosion-proof measures. The energy is mainly released through the frictional heat dissipation between the energy absorber brake pad and the brake drum

When this form of energy absorber is used in high gas mines, it is very easy to generate high temperature due to friction, which will eventually lead to safety accidents

At the same time, after repeated high-temperature work on the brake pads, the rubber of the brake pads is prone to carbonization and hardening due to high temperature, which causes the brake pad rubber to lose its original frictional braking performance, causing the entire energy absorber to lose its original performance. When used underground, there is a very large potential safety hazard
