Description
Technical Field
The utility model relates to the technical field of running anti-unhooking, in particular to an improved running anti-unhooking.
Background
When the templates or the formed plates are hoisted in a workshop, travelling cranes are needed. The lifting hook of the travelling crane is generally provided with a spring-connected anti-drop plate. The lifting rope downwards presses the anti-falling plate to overcome the spring pressure, so that the lifting rope can enter the lifting hook, and at the moment, the anti-falling plate is propped against the inner side of the hook head of the lifting hook under the action of the spring pressure, so that the lifting rope can be prevented from falling off the lifting hook.
However, when unhooking, one hand is required to directly press the anti-release plate against the spring pressure, and then the other hand is required to take out the lifting rope. During field operation, two problems occur:
firstly, the hand needs to firmly pinch the anti-drop plate all the time, and the hand is possibly injured by being squeezed with a little force;
Secondly, the damage of the two parts can be accelerated by frequently pinching the anti-falling plate and the spring, and the anti-falling plate and the spring need to be replaced frequently.
