Description
TECHNICAL FIELD
[0001] The utility model relates to a car stopper technical field, more specifically, an adjustable mine safety car stopper. BACKGROUND
[0002] The car stopper, also known as a car stopper, is one of the important facilities of the coal mine transportation system, and belongs to the anti-car running device, which is generally installed at the top of the slope. It limits the car to stay at the specified position on one hand, and prevents the occurrence of car running accidents on the other hand.
[0003] The car stopper is mainly composed of a rail holder, an operating handle, a buffer spring and a base. The operating handle is used in cooperation with the rotating shaft. Through the action of the operating handle, the opening and closing of the car stopper are realized. The rail holder is used to clamp the wheels of the freely sliding mine car, thereby playing a role in stopping the car. The buffer spring is used to relieve the impact of the mine car on the car stopper, thereby playing a protective role.
[0004] However, the car stopper also has certain defects at present. The main problem is that the rail holder is not compatible with the mine car. Since the distance between the wheels of the mine car and the edge of the mine car is not completely uniform, if the height of the rail holder is too high, the upper end of the rail holder will be blocked at the edge of the mine car, and cannot touch the wheels. Although it can also play a role in stopping the movement of the mine car, the weight of the entire mine car is on the upper end of the rail holder, which makes the force unbalanced, and long-term use can easily lead to the inclination of the rail holder, the mechanical linkage is no longer smooth, and the use is jammed. If the height of the rail holder is too low, the rail holder can indeed be guaranteed to be on the wheels, but the safety problem occurs. UTILITY MODEL CONTENTS
