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

A blocking device and energy conversion technology, applied in transportation and packaging, railway car body parts, forced railway stoppers, etc., can solve the problem of the loss of friction braking performance of brake pad rubber, the carbonization and hardening of brake pad rubber, and the loss of energy absorber. The original performance and other problems can be improved to improve the braking effect, improve the safety, and prevent the speed from running out of control.

Problems solved by technology

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

Embodiment 1

[0040] At present, 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. The vehicle decelerated, braked, and finally stopped.

[0041] The prevention and protection measures for the out-of-control speed of explosion-proof vehicles in underground coal mines:

[0042] Set waste tires on the side of the ramp or at the bottom of the ramp as a buffer to prevent the vehicle from directly rubbing and rigidly colliding with the side wall of the roadway. This mode causes great damage to the vehicle and the driver, and cannot achieve effective braking of the vehicle. The spring-type anti-sports car blocking device has a short braking distance, and in a short distance, the kinetic energy of the vehicle c...

Embodiment 2

[0056] This embodiment discloses an explosion-proof anti-sports car arresting device based on energy conversion, such as Figure 1-3 As shown, it mainly consists of a fixed base 1, a brake drum 2, an explosion-proof energy absorber 3, a brake cylinder 4, a rotating shaft 5, a brake wire rope 6, a cylinder traction rope 7, a high-pressure oil pipe Ⅰ 8, a low-pressure oil pipe 9, and a fuel tank 10 , Oil release valve 11, high-pressure oil pipe II 12, friction plate 13, brake piston 14, moving casing 15, fixed casing 16, pump wheel 17, and turbine 18.

[0057] The fixed base 1 is reliably fixed on both sides of the vehicle running roadway by anchor bolts. The fixed base 1 mainly plays a supporting and fixing role, and the entire blocking device is fixed on the ground of the coal mine underground roadway through 6 mounting holes on the base.

[0058] The brake drum 2 is the main component of the blocking device. The brake drum 2 is connected to the fixed base 1 through the rotat...

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...
