For mobile cranes, the base support part includes a road-ready chassis and frame legs and other load-bearing structures. At the same time, the chassis also provides support for loading on the truck through a central slewing body. The operation provides power; the loading operation part includes the slewing support, the slewing reducer, the slewing hydraulic system, the luffing mechanism composed of the luffing cylinder and the luffing hydraulic system, which enables the upper car to achieve 360-degree full rotation. The lifting mechanism consists of a lifting reducer, a lifting wire rope, a lifting hydraulic system, a power-retractable main arm, a jib, a turntable, a counterweight, a loading room, an electrical control or a lighting system, etc. The purpose of an engineering crane is to lift To pick up objects, a hook is often needed. The existing patent (publication number: CN201921234659.8) discloses a hook, which relates to the field of lifting tools and provides a method that can be operated on the rear side of the hook to swing the anti-detachment baffle. of hook. The hook includes a hook main body, an anti-detachment baffle and a return spring. The anti-detachment baffle is hinged with the hook main body. The return spring and the anti-detachment baffle are cooperatively arranged to cause the anti-detachment baffle to bounce up and close the opening of the hook body. It also includes The baffle pulling structure is hinged with the anti-falling baffle and extends to the rear of the hook body. The hook body supports the baffle pulling structure to prevent the baffle pulling structure from rotating downward. When removing the hook from the hard connector, pull the baffle by hand to pull the structure; during the use of the hook, since the hook has its own opening to facilitate the wire rope to be hung on it, there is often no structure to prevent the wire rope from falling from the hook. Therefore, when the wire rope is hung on the hook and used, there is often a risk of the wire rope falling off. Therefore, in response to the above problems, the applicant proposed a hook with an anti-falling function.

本实用新型的使用方法和优点:该种一种具有防脱落功能的吊钩在使用时,工作过程如下:Usage methods and advantages of the utility model: When this kind of hook with anti-falling function is used, the working process is as follows:
使用者当需要将需要提升的物体挂在吊钩1上的时候,此时使用者只需要用手指拨动连接柱13,然后通过连接柱13带动两个弧形柱11延伸至连接件8中,在弧形柱11的带动下使环形弹簧10收缩,后吊钩1预留出空间,此时可将需要提升的物体挂在吊钩1上,后使用者松开连接柱13,在环形弹簧10的反弹下带动两个弧形柱11插入到两个插筒12中,此时挂在吊钩1上的绳索,受到环形弹簧10的限制,即可避免其脱落造成物体损坏的麻烦,同时其设置结构简单,便于使用者操作,同时通过设置的环形弹簧10具有自动限位的功能;When the user needs to hang the object that needs to be lifted on the hook 1, the user only needs to use his fingers to move the connecting column 13, and then drive the two arc-shaped columns 11 through the connecting column 13 to extend into the connecting piece 8 , driven by the arc-shaped column 11, the annular spring 10 contracts, and the rear hook 1 reserves a space. At this time, the object that needs to be lifted can be hung on the hook 1, and then the user loosens the connecting column 13, and in the ring The rebound of the spring 10 drives the two arc-shaped columns 11 to be inserted into the two sockets 12. At this time, the rope hanging on the hook 1 is restricted by the annular spring 10, which can avoid the trouble of damage to the object caused by its falling off. At the same time, its setting structure is simple and convenient for users to operate. At the same time, the annular spring 10 has an automatic limit function;
锁扣7上拴钢丝绳,吊钩1上挂着待提升的物体,当锁扣7向上移动的时候,为了避免锁扣7上钢丝绳缠绕和吊钩1上待提升物体的钢丝绳缠绕,通过吊钩杆2和第一轴承3以及第二轴承5和锁扣杆6的配合,当钢丝绳转圈的时候,锁扣杆6会在第二轴承5中转动,同时锁扣杆6带动锁扣7转动,同时吊钩杆2在第一轴承3中转动,同时第一轴承3带动吊钩杆2和吊钩1转动,从而避免了钢丝绳转圈导致的缠绕情况出现。A wire rope is tied to the lock 7, and the object to be lifted is hung on the hook 1. When the lock 7 moves upward, in order to avoid the entanglement of the wire rope on the lock 7 and the entanglement of the wire rope of the object to be lifted on the hook 1, through the hook The cooperation between the rod 2 and the first bearing 3 and the second bearing 5 and the lock rod 6 means that when the wire rope rotates in a circle, the lock rod 6 will rotate in the second bearing 5, and at the same time the lock rod 6 drives the lock 7 to rotate. At the same time, the hook rod 2 rotates in the first bearing 3, and the first bearing 3 drives the hook rod 2 and the hook 1 to rotate, thereby avoiding the entanglement caused by the wire rope turning in circles.
