Hasp split arrester and sports car protection device

Abstract

The invention discloses a hasp split arrester and sports car protection device, only one locking movable component of a latch hook assembly is adopted, that is, a lock plate rotates around a pin shaft, the movement belongs to low pairs, the action links are few, the movement form is concise, and the probability of failure is greatly reduced. Meanwhile, the lock plate is specifically configured tobe divided into a first part located on the hook base side and a second part located on the hook head side with the overhead hole as the boundary, and the whole lock plate is equivalent to a lever. The first part shields part of the hook groove in the initial state, and when the first part is directly acted by the locked component, the lock plate rotates to cause the second part to gradually shield part of the hook groove, so the locked component is reversely restrained, and obviously, the action of the lock plate meets the requirements that the larger the dragging force of the locked component is, the tighter the locking is; and locking reliability is high.

Description

technical field [0001] The invention relates to a buckle split type barrier, and the invention also relates to a sports car protection system device equipped with the buckle split type barrier. Background technique [0002] According to the provisions of the "Safety Regulations for Coal Mine" and "Safety Regulations for Metal and Nonmetal Mine", sports car protection devices capable of stopping vehicles with broken ropes and uncoupling shall be installed in inclined roadways, and protective devices for sports cars shall be installed near the slope change point in the upper flat yard. Prevent unconnected vehicles from slipping into the car stopper of the inclined lane, and set up a barrier that can prevent unconnected vehicles from continuing to run down the slope at a point greater than 1 train length below the slope point. [0003] The aforesaid barriers conventionally include netting-type barriers, bottom-rising barriers, bottom-rising buckle-type barriers, and buckle spli...

AI Technical Summary

Problems solved by technology

Due to the use of multiple low pairs, the operation reliability of the low pair is relatively poor, especially in the environment with high humidity and dust under the mine, it is very easy to cause the low pair, specifically the block of the guide slider assembly, once The guide slider assembly is stuck, and the position of the push rod occupies part of the lock of the hook body, which reduces the locking effect of the hook body
