Hoister falling prevention test detacher

Abstract

The invention relates to a hoister falling prevention test detacher which comprises a fixed jaw fixed onto a body. A movable jaw is distributed on one side of the fixed jaw and hinged onto the body, an open or closed lifting hook is formed by the movable jaw and the fixed jaw, the other end of the movable jaw extends out to form a first swing arm, the tip of the first swing arm contacts with the tip of one end of a second swing arm, a pin is arranged on the outer side of the other end of the second swing arm and used for stopping the second swing arm from moving, the pin is positioned on a movable groove in the body and matched with a shifting fork hinged onto the body, and the shifting fork is connected with an operation rod. By the mode, the hoister falling prevention test detacher has the advantages of simple structure, high detaching speed, convenience in operation and high bearing load.

Description

technical field

[0001] The invention relates to an anti-drop tester, in particular to a decoupling device for an anti-drop test of a hoist. Background technique

[0002] The hoist mentioned here is a construction machine used for external wall operations in construction projects. According to relevant national regulations, after the design of the hoist is completed, an anti-drop test is required to test whether the anti-drop safety of the hoist is reliable. Use the uncoupling device to loosen the lifting device of the hoist for the drop test. In the prior art, the decoupling device has the disadvantages of complex structure, slow decoupling speed, inconvenient operation, and small load, which is far from meeting the needs of the hoist anti-drop test. . Contents of the invention

[0003] In view of the above-mentioned defects, the main technical problem to be solved by the present invention is to provide a lifter anti-dropping test decoupling device with simple structure, ...
