Description

A hook with anti-falling function

Technical field

The utility model relates to the technical field of hooks, and in particular to a hook with an anti-falling function.

Background technique

Engineering cranes generally consist of a base support part and a loading operation part. 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.

Detailed ways

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only part of the embodiments of the present utility model, not all implementations. example.

Referring to Figures 1-3, a hook with an anti-falling function includes a hook 1. Two connectors 8 are fixedly connected to the circumferential outer wall of the hook 1, and both connectors 8 are fixedly connected. There is an arc-shaped cylinder 9, and an annular spring 10 is provided in the arc-shaped cylinder 9. One end of the annular spring 10 is installed on the arc-shaped column 11;

It also includes a hook rod 2. The top of the hook rod 2 is rotatably connected to a first bearing 3. The first bearing 3 is installed in the counterweight block 4. The top of the counterweight block 4 is installed with a second bearing. 5. The inner ring of the second bearing 5 is rotatably connected with a locking rod 6 .

In the utility model, a lock 7 is fixedly connected to the top surface of the lock rod 6, a "T"-shaped hole is provided on the top of the counterweight block 4, and the second bearing 5 and the lock rod 6 are arranged on in the "T" shaped hole.

In the present utility model, a hook rod 2 is fixedly connected to the top of the hook 1, an inverted "T"-shaped hole is provided at the bottom of the counterweight block 4, and the first bearing 3 and the hook rod 2 are arranged on Pour it into the "T" shaped hole.

In the present utility model, two plug-in barrels 12 are fixedly connected to the circumferential outer wall of the hook 1, and the two arc-shaped columns 11 are respectively plugged into the two plug-in barrels 12.

In the present utility model, a connecting column 13 is fixedly connected to the two arc-shaped columns 11 , and the connecting column 13 is in contact with the inner wall of the hook 1 .

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:

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;

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.
