Description

Inclined drift anti-running system

Technical Field

The utility model belongs to the technical field of the roadster technique of preventing running and specifically relates to indicate a roadster system is prevented in inclined drifts.

Background

In the prior mine rail transportation process, especially an inclined shaft and drift, the occurrence of tramcar running accidents is more, so that equipment and shaft and drift are damaged, even serious accidents such as casualties, mine production stoppage and the like are caused.

Over the years, pneumatic, electric and linkage anti-runaway systems are used in mines, and all the systems have defects, and the pneumatic anti-runaway systems need to manually operate valve switches, so that the labor intensity is high; the electric and linkage anti-running system has the problems that when the mine car runs to the protective system, the car stopping rail is not opened, and the mine car directly hits the protective system, so that the mine car must be corrected frequently, and the trouble is brought to field use. The inclined drift anti-running system adopts a fixed position blocking net type structure mostly, namely, the car needs to walk to the blocking net position to stop the car after the steel wire rope is broken, and the defect of the mode is that: when the breaking position of the blocking net and the steel wire rope is far away, the lift car can obtain higher speed, the blocking net is easily broken by larger impact force, and the safety of the lift car is greatly reduced. Although some rope breaking stopping systems are arranged on the car, the rope breaking stopping systems are related to an electric system, are complex, have poor stability and are easy to malfunction.

Disclosure of Invention

In order to solve the problem that exists among the prior art, the utility model provides a roadster system is prevented running to inclined drifts, braking force is big, can realize the quick braking of disconnected rope.

The utility model provides a technical scheme that its technical problem adopted is:

the utility model provides a system of starting running is prevented in inclined drifts, includes car, inclined rail and wire rope, and the car lateral wall is equipped with the leading wheel, and wire rope walks around the leading wheel and pulls the car along the inclined rail motion, and its characterized in that includes and hinders the piece of stopping fixed with wire rope, and the guide part is established to the car, hinders the piece of stopping and guide part clearance fit, hinders and is equipped with the socket under the piece of stopping. The guide wheel has a guiding function, so that the tensioning direction of the steel wire rope is consistent with that of the stopping part, and the steel wire rope bypasses the guide wheel and is fixed with the stopping part, so that the lift car is pulled to move forwards or backwards. The working principle of the car is as follows: the elevator car obliquely moves forward by pulling the steel wire rope by the winch, and the elevator car obliquely moves backward by pulling the steel wire rope by the winch to prevent stalling. When the steel wire rope is suddenly broken, the stopping piece falls down by means of the dead weight and is inserted into the socket, and therefore the car is stopped.
