Description

Technical Field

[0001] The utility model relates to the technical field of engineering machinery, in particular to a production line capable of automatically hanging and placing a hook. Background Art

[0002] The hook is mainly used for the automatic locking and lifting of heavy objects. It has a simple structure. When assembling higher and heavier materials on the assembly line, it is necessary to hook the materials multiple times for lifting and relocation. Each time the hook is hooked, it is necessary to climb above the heavy object, align the hook with the lifting point, and direct the crane in the factory to reel in the rope for lifting. During the lifting, the personnel must stay away from the workpiece. After the relocation is completed, the hook needs to be removed. During the relocation process, the heavy objects need to be lifted multiple times, and the personnel need to perform multiple high-altitude hanging and placing operations, which not only affects the efficiency of transportation, but also creates unsafe factors for multiple high-altitude operations.

[0003] At present, the same industry uses special lifting accessories, which are professionally designed for lifting heavy objects. They are often costly, not universal, and cannot be promoted on a large scale. Those who use universal hooks often use special hanging points and special lifting tools or accessories.

[0004] In summary, the prior art has the above-mentioned defects:

[0005] (1) When using the universal hook, it is necessary to work on the production line, climb up to hang the rope and collect the rope, and personnel need to climb up many times;

[0006] (2) The universal hook is equipped with a safety anti-unhooking device. During use, the anti-unhooking device will be reset after the rope is hung;

[0007] (3) Another person is required to operate the crane for lifting and retracting the rope. Summary of the invention

[0008] Purpose of the utility model: In order to overcome the shortcomings of the background technology, the utility model requests to disclose a production line that can automatically hang and place hooks, and a single-person operated crane can implement automatic hanging and anti-dropping of high-altitude lifting points. After the lifting operation, it can achieve automatic unhooking, reducing the problem of manual hanging and retracting ropes, thereby improving the lifting efficiency on the production line, eliminating manual climbing operations, and improving the safety of operations.

[0009] Technical solution: The production line disclosed in the utility model can automatically hang and place hooks, including:

[0010] Rings;

[0011] A locking balancing block, wherein the locking balancing block is connected to the lifting ring via a first pin shaft and can freely rotate around the first pin shaft;

[0012] A biasing hook, the middle part of which is connected to the locking balance block through a second pin shaft and can rotate freely around the second pin shaft;

[0013] A position-limiting counterweight, which is fixed on the locking balance block and is located on one side of the hook body of the biased weight hook, and is used to limit the position in the upward rotation direction of the hook body of the biased weight hook;

[0014] In the balanced state before lifting, the limit counterweight restricts the hook body of the eccentric hook from rotating upward, and the hook body opening is horizontally tilted upward; in the lifting preparation state, the handle of the lifted object enters from the hook body opening to the bottom of the hook body; in the lifting state, the lifting ring moves upward, and the handle drives the hook body of the eccentric hook to disengage from the limit counterweight and rotate downward until the hook head of the hook body and the locking balance block lock the handle.

[0015] Furthermore, the top of the locking balance block is connected to the bottom of the lifting ring. In the balanced state before lifting, the second pin shaft and the limiting counterweight are respectively located on both sides vertically below the first pin shaft. When the handle drives the hook body of the eccentric hook to rotate downward, the second pin shaft moves to be directly below the first pin shaft.

[0016] Furthermore, the locking balance block is fixed by two spaced-apart pieces arranged in parallel via a pin, and the weight-biasing hook is located in the middle interlayer of the locking balance block and can rotate freely in the interlayer.

[0017] Furthermore, the limiting counterweight is fixed to the locking balance block by means of a fixing screw.

[0018] Beneficial effects: Compared with the prior art, the advantages of the utility model are: the automatic hanging hook designed based on the principle of vertical downward gravity has a better effect when hanging and placing the hook during high-altitude operations, eliminates manual high-altitude operations, and improves the safety of operations; reduces the time for high-altitude operations, and greatly improves efficiency.

[0021] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0022] like Figure 1 and 2 The production line shown can automatically hang and place the hook, including: a lifting ring 1; a locking balance block 2; a biasing hook 4; and a limiting counterweight 6.

[0023] The top of the locking balance block 2 is connected to the bottom of the lifting ring 1. The locking balance block 2 is connected to the lifting ring 1 through the first pin shaft 3 and can rotate freely around the first pin shaft 3. The locking balance block 2 is fixed by two parallel and spaced pieces through the pin shaft, and the weight-biasing hook 4 is located in the middle layer of the locking balance block 2. The middle part of the weight-biasing hook 4 is connected to the locking balance block 2 through the second pin shaft 5 and can rotate freely around the second pin shaft 5; the limiting counterweight 6 is fixed to the locking balance block 2 through the fixing screw 7 and is located on one side of the hook body of the weight-biasing hook 4, and is limited in the upward rotation direction of the hook body of the weight-biasing hook 4. The second pin shaft 5 and the limiting counterweight 6 are respectively located on both sides of the vertical lower side of the first pin shaft 3.

[0024] In the balanced state before lifting, the limiting counterweight 6 limits the upward rotation of the hook body of the eccentric hook 4, and the hook body opening is horizontally biased upward; in the lifting preparation state, the handle of the hoisted object enters from the hook body opening to the bottom of the hook body; in the lifting state, the lifting ring 1 moves upward, and the handle drives the hook body of the eccentric hook 4 to disengage from the limiting counterweight 6 and rotate downward, and the second pin shaft 5 moves to the bottom of the first pin shaft 3 until the hook head of the hook body and the locking balance block 2 lock the handle.

[0025] The patented automatic hanging hook is designed to be vertically downward by gravity.

[0026] like Figure 2 As shown:

[0027] When the weight is lowered to the ground, the hook 4 is pulled back and the weight is released, so that the hook 4 can move back and forth, and the weight is released ...
