Abstract
The utility model discloses a self-reset type car retarder. A transmission shaft is arranged on a frame and provided with two retarding claws, and a transmission arm is installed at one end of the transmission shaft. The self-reset type car retarder is characterized in that a self-reset spring is arranged on a shaft body of the transmission shaft between the retarding claws, and connected with a support cross frame in front of the car retarder, a hydraulic cylinder is installed on the transmission arm, and a hydraulic pump station for providing hydraulic pressure for the hydraulic cylinder is arranged. In the utility model, a hydraulic system or a pressure system is adopted, the remote operation is conducted, and due to the self-reset spring, the retarding claws can reset automatically, so that the manual operation is replaced, the work efficiency is improved, the hidden safety hazard is reduced, and the automatic level of the inclined drifts and inclined shafts can be improved.
Description
Technical field
The utility model relates to mine transportation safety equipment, prevents the stop device of mine car sport car in particular for coal mine sloping lane grade change point place.
Background technology
At present, the stop device that bargh adopts, its structure be, is provided with transmission shaft on framework, and two resistance claws are installed on transmission shaft, and transmission shaft one end is equipped with transmission arm, and manual control handle is installed on the transmission arm.Mine car by the time manually closely stir control handle resistance claw opened and closed.This manual work mode is inefficiency not only, and personal safety can not get guaranteeing, has bigger potential safety hazard.
Summary of the invention
The utility model provides a kind of simple in structure, safe and reliable self-resetting type stop device for solving the deficiency of above-mentioned stop device manual work mode.
The structure of this self-resetting type stop device is: be provided with transmission shaft on framework, two resistance claws are installed on transmission shaft, transmission shaft one end is equipped with transmission arm, it is characterized in that, transmission shaft axis body between the resistance claw is provided with self-recoiling spring, self-recoiling spring is connected with stop device the place ahead supporting cross bearer, and hydraulic ram is installed on the transmission arm, and a hydraulic power unit that hydraulic pressure is provided for hydraulic ram is set.
When mine car is transferred, the control cock of remote servicing hydraulic ram at first, hydraulic ram promotes transmission arm and opens resistance claw, and car passes through smoothly; When mine car by after under self-recoiling spring pulling the stop device resistance claw reset.When mine car is up, mine car take advantage of a situation resistance claw overwhelm by, by the back resistance claw under the self-recoiling spring effect, the resistance claw pull-up is resetted.
Above-mentioned hydraulic ram and hydraulic power unit can substitute with air cylinder and air pressure station.
The good effect of this self-resetting type stop device is:
1, adopt hydraulic efficiency pressure system or pressure system, remote servicing automatically resets resistance claw by self-recoiling spring, thereby has replaced manually having improved work efficiency, has reduced potential safety hazard.
2, the utility model can cooperate electronic control system and lifting winch or gig to realize synchronized operation and synchro control, improves the automatization level of inclined gallery, inclined shaft hoisting work.
