Sensitive adjustable pull rod ball type anti-car device

Abstract

The invention provides a sensitive and adjustable drag-link-ball-bead sliding-down-proof device, and belongs to the technical field of mine auxiliary transportation safety devices. The sensitive and adjustable drag-link-ball-bead sliding-down-proof device comprises a vehicle stopping mechanism, opening controlling mechanisms, a touch mechanism and an adjustable zipper connecting rod; the vehicle stopping mechanism comprises vehicle stopping bases, vehicle stopping baffles, a vehicle stopping rotating shaft, a vehicle-stopping-rotating-shaft spring, buffering springs and buffering zippers; theopening controlling mechanisms are arranged on the vehicle stopping bases, and comprise sleeves, column cores slidingly arranged in the sleeves, ball beads, first reset springs, L-shaped baffles, baffle rotating shafts and second reset springs; the touch mechanism comprises touch bases and a pendulum bob rotationally arranged on the touch bases, and the pendulum bob rotates forwards in a one-way manner; the adjustable zipper connecting rod comprises a connecting rod and a zipper which are horizontally arranged, the first end of the connecting rod is connected with second stopping arms of the L-shaped baffles, an adjusting screw is in threaded connection on the second end of the connecting rod, the first end of the zipper is connected with the adjusting screw, and the second end of the zipper is connected with the pendulum bob. The sliding-down-proof device is sensitive in response, adjustable in starting movement time and capable effectively avoiding malfunctions.

Description

technical field [0001] The invention relates to the technical field of safety devices for auxiliary transportation in mines, in particular to a sensitive and adjustable tie rod ball type anti-running device. Background technique [0002] The lifting and transportation of inclined shafts is an important part of the entire mine transportation system, and it is also an important link in mine safety production. It is responsible for lifting coal, rocks, lowering equipment and materials, and sometimes it is used to lift people. However, due to reasons such as decoupling of mine cars and broken ropes, it has become a frequent area for mine transportation accidents. In the daily mining and production of coal mines, accidents in coal mine transportation are all accidents worthy of vigilance in terms of the number of occurrences and the impact caused, and among them, accidents caused by mine trucks and sports cars are one of the most serious accidents. Sports car accident refers to ...
