Tripping gear

Abstract

The invention relates to a tripping gear which comprises a support, a first hinge pin, a first hook, a second hinge pin, a second hook and a lifting mechanism. The first hook is hinged on the support via the first hinge pin, the lifting mechanism is connected with the first hook, the first hook rotates around the first hinge pin under the action of the lifting mechanism, the second hook is hinged on the support via the second hinge pin, a first gear is fixedly mounted on the first hinge pin, a second gear is fixedly mounted on the second hinge pin, the first gear and the second gear are in engagement transmission, one end of the first hook and one end of the second hook are respectively provided with a first hook lug and a second hook lug, the first hook lug and the second hook lug are staggered, and side surfaces of the first hook lug and the second hook lug are abutted with each other to form a hooking space. The tripping gear has the advantages that the mode that the gears are in linkage with the double hooks is adopted, the problem that load drops unstably when the load is released, or a hook and a steel wire rope connected with the hook are rebounded when the load is released suddenly is solved, operation equipment is protected, and the tripping gear is simple in structure and convenient in operation.

Description

(1) Technical field [0001] The invention relates to a decoupling device. (2) Background technology [0002] With the continuous development of engineering technology, the use status of the load hook of lifting equipment has also changed accordingly. For example, lifting a load, releasing it in the air, impacting the load-bearing object at the corresponding position below, or releasing the falling object during the drop test. Usually, a single hook equipped with general lifting equipment is used. If the hook is shallow, accidental falling accidents often occur. If the hook is deep, it is difficult to release the load or fall. If it is forced to release, it will generate a large horizontal force and force. The impact of the counter force makes the load unstable when it falls, or the steel wire rope and the hook connected to the hook rebound when the load is suddenly lost, which is easy to damage the operating equipment. (3) Contents of the invention [0003] In order to ma...
