The invention discloses a hook mechanism which comprises a hook, an air cylinder and an air cylinder mounting seat which are sequentially connected, the air cylinder mounting seat is mounted on a tractor, the tractor is hinged to the hook, the air cylinder mounting seat is hinged to the air cylinder, and the air cylinder is hinged to the hook. Compared with the prior art, the use performance of equipment is realized, and the equipment cost is reduced; and the operation is convenient, efficient and rapid. The cylinder is adopted as power, so that the hook can release the tackle with larger tonnage weight, that is, the hook device can pull the tackle with larger tonnage weight to complete the functions of hooking and releasing the tackle. When the tackle is released, the air cylinder can bear large outward pulling opposite force; the pulley hinged shaft and the hinged shaft of the hook fixed on the tractor are on the same stress center line, so that the cylinder is small in stress, environment-friendly, energy-saving and low in cost.
本发明公开了一种挂钩机构,包括顺次连接的挂钩、气缸和气缸安装座,所述气缸安装座安装在牵引车上,所述牵引车与挂钩铰接,所述气缸安装座与气缸铰接,所述气缸与挂钩铰接。与现有技术相比,本发明实现设备使用的性能,并降低了设备成本;操作方便、高效、迅速。本发明采用气缸作为动力,使挂钩能释放较大吨位重量的滑车,即本发明能牵引较大吨位重量的滑车完成挂钩和释放滑车的功能。释放滑车时,气缸能承受较大外拉的反向力;滑车铰轴与挂钩固定于牵引车上的铰轴在同一受力中心线上,使气缸受力小,气缸环保节能且成本低。
