Description

Technical Field

[0001] The utility model relates to the technical field of hoisting locks, in particular to an anti-falling hoisting rigging. Background Art

[0002] Hook rigging is the most common type of sling in lifting machinery. The hook is often suspended on the wire rope of the lifting mechanism with the help of a pulley block and other components. The existing anti-drop hook is to prevent the objects being lifted from falling off during the operation of the hook rigging. On the basis of the original hook, a hook engaging with the hook hole is added to make the original hook form a closed state, thereby preventing the objects being lifted from falling off.

[0003] For example, the utility model with application number CN202120576724.6 discloses an anti-unhooking hook rigging, in which a bolt-engaging lifting structure is added to the hook engaged with the hook to control the opening and closing of the entire anti-unhooking hook. The device solves the problem that the goods are easily detached from the hook, resulting in low safety of the hook. However, the prior art uses bolts, and when connecting with objects during use, it is necessary to use a special tool to turn the bolts, and the operation is relatively cumbersome. At the same time, although a special tool for placing and turning the bolts is provided on the surface of the hook, the on-site conditions are relatively complicated and the tools are relatively small during work, so they are easy to lose, which brings unnecessary trouble to the work.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0025] The utility model is further described in detail below in conjunction with the full text.

[0026] Combined with Figure 1-Figure 4 A kind of anti-falling lifting rigging comprises a hook 1, one end of which is rotatably connected with a locking tongue 2 for locking, a stopper 3 is slidably connected to the locking tongue 2, a quick locking device 4 for locking the locking tongue 2 and the stopper 3 is installed inside the hook 1, the hoisted objects are hung in the hook 1, and the hook 1 is closed by the locking tongue 2 to prevent falling.

[0027] When the utility model is implemented, Figure 1 , Figure 2 and Figure 4As shown, the quick locking device 4 includes a first limiting rod 401 slidably connected to the hook 1 for locking the lock tongue 2 and a second limiting rod 402 slidably connected to the hook 1 for locking the stop block 3. A limiting plate 403 and an adjusting spring 404 are installed on the outer side of the first limiting rod 401. A first connecting hole 8 for cooperating with the first limiting rod 401 is provided in the hook 1 and the lock tongue 2. A second connecting hole 9 for cooperating with the second limiting rod 402 is provided in the hook 1 and the stop block 3. The outer side of the first connecting hole 8 is connected to a moving cavity 801, and the limiting plate 403 and the adjusting spring 404 are located at the moving cavity 801. In the cavity 801, when the first limit rod 401 and the second limit rod 402 are manually pulled to slide, the limit plate 403 pushes the adjustment spring 404 to compress, so that the first limit rod 401 and the second limit rod 402 are away from the block 3 and the lock tongue 2, and unlocking can be achieved. When the hand is released, the adjustment spring 404 stretches and pushes the first limit rod 401 and the second limit rod 402 to slide into the block 3 and the lock tongue 2 to achieve locking. The first limit rod 401 and the second limit rod 402 can slide in the first connecting hole 8 and the second connecting hole 9 to lock and unlock the block 3 and the lock tongue 2.

[0028] The stopper 3 and the locking tongue 2 are both provided with through holes for cooperating with the first limiting rod 401 and the second limiting rod 402 .

The connection to form a U-shaped structure can be achieved by quickly pulling to achieve unlocking and locking.

[0030] When the utility model is implemented, Figure 1 and Figure 2 As shown, a limiting groove 5 for cooperating with the stopper 3 and the lock tongue 2 is provided in the hook 1, and the lock tongue 2 is hinged on the hook 1, and the hinge is realized by an axis and an axis hole. The lock tongue 2 can rotate to enter the limiting groove 5, and a slide groove 6 is provided on the lock tongue 2. A slider 7 for cooperating with the slide groove 6 is installed at the lower end of the stopper 3. The stopper 3 slides in the slide groove 6 through the slider 7 and moves to the limiting groove 5 to realize limiting.

[0031] A threaded column for installation is installed on the hook 1.

[0032] The working principle of the utility model is as follows: first, the hoisted cargo is hung on the hook 1 and manually pulled, the first limit rod 401 and the second limit rod 402 slide, and the limit plate 403 pushes the adjustment spring 404 to compress, so that the first limit rod 401 and the second limit rod 402 are away from the block 3 and the lock tongue 2, and the block 3 slides in the slide groove 6 through the slider 7 and moves to the limit groove 5 to achieve limiting, and at the same time the lock tongue 2 rotates into the limit groove 5, when the hand is released, the adjustment spring 404 stretches and pushes the first limit rod 401 and the second limit rod 402 to slide into the block 3 and the lock tongue 2 to achieve locking, the first limit rod 401 and the second limit rod 402 can slide in the first connecting hole 8 and the second connecting hole 9, lock and unlock the block 3 and the lock tongue 2, and complete the closure of the hook 1.

[0033] The above describes the utility model and its implementation methods, which is not restrictive. What is shown in the full text is only one of the implementation methods of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it, without departing from the purpose of the invention of the utility model, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the utility model.
