The invention relates to the technical field of hoisting equipment, and provides a lifting hook for a tower crane, which comprises a lifting hook frame, a rotating part is movably embedded in the center of the interior of the lifting hook frame, two first pulleys are fixedly sleeved on the outer surface of the rotating part, eccentric wheels are fixedly mounted on the opposite sides of the rotating part, and the rotating part is movably embedded in the lifting hook frame. According to the embodiment of the invention, through linkage structures such as the eccentric wheels and the pump cylinder, when the lifting hook is used and lubricating oil needs to be added to a rotating part, only a one-way valve needs to be opened, the lubricating oil can be added to the rotating part, and then the lubricating oil can be added to the rotating part, so that the lubricating oil can be added to the rotating part, and the lubricating oil can be added to the rotating part. The lubricating oil can be automatically added to the lifting hook when the lifting hook is used, the situation that the service life of the lifting hook is affected due to abrasion caused by lack of the lubricating oil is prevented, meanwhile, the step of manually adding the lubricating oil by workers is omitted, and the operation complexity of the workers is greatly reduced.

    本发明涉及吊装设备技术领域,提供了一种塔式起重机用吊钩,包括:吊钩架,所述吊钩架的内部中心处活动嵌设有转动件,所述转动件的外表面固定套设有两个第一滑轮,所述转动件相背的一侧均固定安装有偏心轮,两个所述偏心轮的内部均开设滑轨,两个所述滑轨的内表面均设有活动杆,两个所述活动杆的外侧均活动连接有拉杆,本发明实施例中,通过偏心轮与泵筒等联动结构,使吊钩在使用时,需要对转动件添加润滑油时,只需要打开单向阀,就可以使吊钩在使用时自动对其添加润滑油,防止吊钩因为缺少润滑油出现磨损影响到其的使用寿命,同时减少了人员手动添加润滑油的步骤,大大减少了工作人员操作的繁琐程度。
