Manual linkage car arresting device

Abstract

The invention discloses a manual linkage car arresting device and belongs to car arresting devices of mine cars under coal wells. The manual linkage car arresting device comprises a linkage mechanism, a pedestal, an arresting claw and a buffer spring, the linkage mechanism is arranged in the pedestal, two corresponding sides of the pedestal are connected with the arresting claw, the arresting claw is hinged to the pedestal, a buffer spring is arranged at the joint between the arresting claw and pedestal, one end of a connecting bar is hinged to the arresting claw while the other end is hinged to a first driver, a connecting bar is hinged to the tail end of the arresting claw, the two connecting bars are connected through the first driver, the manual linkage car arresting device further comprises a second driver and a manual adjusting device, one end of the second driver is hinged to the cylinder while the other end is hinged to the first driver, and the cylinder is arranged in the pedestal; the manual adjusting device comprises an operation rod and a shaft, one end of the operation rod is vertically fixed on one end of the shaft, and the other end of the shaft runs through the pedestal and is firmly connected with the first driver. The manual linkage car arresting device is large in rotation moment, convenient to adjust, capable of manually operating a car arrester without power or compressed air, and safe and reliable.

Description

technical field [0001] The invention relates to a car stop device for underground mine cars in coal mines, in particular, the invention relates to a manual linkage car stop device. Background technique [0002] At present, all kinds of mining vehicles in the production process of my country's coal mines are the main means of transportation for the materials and materials needed in coal mines. Since the underground transportation track is limited by the floor of the roadway, it is necessary to use a car stopper to stop and stabilize the vehicle during vehicle transportation and loading and unloading. This is also the most critical link in the transportation work, which can easily cause sports car accidents in inclined lanes. Therefore, the car arrester determines the reliability of transportation safety to a large extent. However, due to the direct link transmission of the previous car arrester linkage device, the rotational moment is small, and the phenomenon of the car arr...

AI Technical Summary

Problems solved by technology

However, due to the direct link transmission of the previous car arrester linkage device, the rotational moment is small, and the phenomenon of the car arrester being collided and opened is prone to occur, resulting in off-road accidents. Accidents frequently occur

And the pneumatic car arrester cannot be operated when the power is cut off or there is no compressed air, which may bring safety hazards
