Problems solved by technology

These technical measures have the following deficiencies: 1. The system is complex, there are many fault points, and the probability of failure is high; "Passive protection technology", even if the "sports car" is intercepted, due to the high speed and high impact energy, it will cause damage to the mine car and the intercepting device, resulting in large economic losses

Embodiment Construction

[0012] refer to figure 1 The embodiments of the present invention are further described. From figure 1 It can be seen that the structure of the present invention is: on the wheel hub 5 of the mining wheel, 4 force transmission grooves 2 are evenly distributed radially, and each force transmission groove 2 is equipped with an inertial friction block 4 reset by a return spring 3, each There is a limit pin 6 on the inertial friction block 4; in addition, a brake disc 7 is fixedly connected to the axle 1, and the brake disc 7 is provided with a circle of friction surfaces matched with the inertial friction block.

[0013] In order to increase the friction resistance torque, the friction surface between the brake disc 7 and the inertial friction block 4 is designed as an inclined plane to increase the friction area.

Abstract

The invention discloses a wheel speed-limitation structure for a mine running-resisting car; the wheel speed-limitation structure is characterized in that: 2-4 force transferring grooves are uniformly distributed on a wheel hub of the mine car wheel, and an inertia friction block which is reset elastically by pulling force is arranged in each force transferring groove; a concave brake disc is fixedly connected on an axle, and the friction surface of the concave brake disc corresponds to the inertia friction block. The wheel speed-limitation structure has the advantages that the principle that wheel rotating speed controls the speed of a mining car in a degeneration way is adopted, so as to realize the effect of preventing the running car actively, the structure is safe and reliable; compared with the cost of the running-resisting car system, the disaster prevention cost is greatly reduced.

Description

technical field [0001] The present invention relates to mining vehicles, and more particularly to wheels for mining vehicles. Background technique [0002] One of the major safety accidents that occur frequently in mine production is the "sports car accident in an inclined shaft or laneway" caused by various reasons. The "sports car accident" poses a great threat to the safety of on-site workers and equipment. Especially in the event of a sports car accident on a steep, long-distance slope, the sports car has a high speed, inertia and impact energy, and it will cause serious safety accidents when it hits workers or equipment. Therefore, it is urgent to adopt advanced safety equipment and technology to prevent such accidents in mine production. [0003] At present, the technology of preventing "sports car accident" at home and abroad mainly includes: 1. measure the pulling force of the wire rope pulling the mine car with a sensor to judge whether a "sports car accident" has ...
