Tripping gear

Abstract

本实用新型涉及一种脱钩装置,其包括支架、第一销轴、第一挂钩、第二销轴、第二挂钩和提拉机构,第一挂钩通过第一销轴铰接在支架上,提拉机构与第一挂钩连接,在提拉机构的作用下,第一挂钩绕第一销轴转动,第二挂钩通过第二销轴铰接在支架上,第一销轴上固定安装有第一齿轮,第二销轴上固定安装有第二齿轮,第一齿轮和第二齿轮啮合传动,第一挂钩和第二挂钩的一端各自设有第一钩舌和第二钩舌,第一钩舌和第二钩舌相错开且侧面相互紧靠形成钩物空间。本实用新型的优点在于:采用齿轮联动双挂钩的方式,克服了释放载荷时使载荷下落时失稳,或连着挂钩的钢丝绳和挂钩在突然失去载荷时发生回弹,保护操作设备,而且装置结构简单,操作方便。
The utility model 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 mesh 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 to 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.
