Description

Technical Field

[0001] The embodiments of this utility model relate to the field of hook auxiliary tools, specifically, to a hook device. Background Technology

[0002] With the continuous expansion of industrial scale and the increasing demands for production efficiency, the safety and efficiency of lifting operations have become increasingly important. As the core equipment for lifting operations, the reliability of the connection between the crane's hook and the load to be lifted directly affects the success or failure and safety of the operation.

[0003] The load to be lifted is usually connected to a looped steel wire rope, which is then hooked onto the crane's hook to achieve the connection. Traditional hooking methods rely primarily on manual operation. When dealing with heavy steel wire ropes, operators need to expend considerable physical strength to lift them, which not only increases labor intensity but also reduces operational efficiency. Furthermore, manual hooking is prone to accidents, such as the steel wire rope slipping from the operator's grasp, posing a threat to their personal safety. Currently, some auxiliary hooking tools exist on the market, but most have complex designs and require numerous operating steps, making them difficult to learn quickly and failing to meet the needs of efficient and convenient operation in actual work.

[0004] Therefore, developing a hook and hanger device that is simple in structure, easy to use, and can reduce labor intensity and improve hanging efficiency and safety is of great practical significance. Utility Model Content

[0005] To overcome the above-mentioned defects, the embodiments of this utility model provide a hook hook device, which solves the technical problems in the related technology where it is time-consuming and laborious to manually attach the wire rope to the hook, and the current auxiliary tools have complex structures and are cumbersome to operate.

[0006] According to one aspect, at least one embodiment of the present invention provides a hook hook device for hooking a wire rope connected to a load to be lifted into the hook. An anti-detachment component is oscillatingly installed inside the hook. The anti-detachment component abuts against the inner annular wall of the hook to form a closed annular space and prevent the wire rope inside the hook from detaching. The device includes a sleeve and a lever. The outer peripheral wall of the sleeve is rotatably mounted on the side of the hook. The lever passes through the sleeve, and its two ends are a force-applying end and a force-receiving end, respectively. The force-receiving end of the lever is provided with a hook portion. The lever can hook the wire rope with the hook at the force-bearing end, and rotate around the rotation point of the sleeve under the action of the external force at the force-applying end, so that the force-bearing end drives the wire rope to lift up and the wire rope slides into the hook along the lever.

[0007] For example, in at least one embodiment of the present invention, a hook device further includes: It also includes a clamping belt for clamping onto a hook by means of connecting components at both ends. A mounting plate is provided in the middle of the clamping belt, and a rotating shaft is provided on the outer peripheral wall of the sleeve. The rotating shaft is rotatably mounted on the mounting plate.

[0008] For example, in at least one embodiment of the present invention, a hook device further includes: The connecting assembly includes an internal threaded sleeve disposed at one end of the cartridge and an external threaded post rotatably disposed at the other end of the cartridge, the external threaded post being used to thread into the internal threaded sleeve.

[0009] For example, in at least one embodiment of the present invention, a hook device further includes: The connecting assembly includes a connecting bolt and a connecting screw hole at the end of the cartridge. Both ends of the cartridge have the connecting screw hole. The connecting bolt is used to be installed into the two connecting screw holes at both ends of the cartridge to fix the cartridge.

[0010] For example, in at least one embodiment of the present invention, a hook device further includes: The sleeve sidewall has a first locking pin hole, the lever has a plurality of second locking pin holes along its length, and the hook device further includes a locking pin, which is used to simultaneously pass through the first locking pin hole and one of the second locking pin holes to fix the lever.

[0011] For example, in at least one embodiment of the present invention, a hook device further includes: The lever has an external thread, the inner wall of the sleeve has an internal thread, and the lever is threadedly connected inside the sleeve.

[0012] For example, in at least one embodiment of the present invention, a hook device further includes: The lever has anti-slip texture on the force-applying end.

[0013] For example, in at least one embodiment of the present invention, a hook device further includes: The lever has an auxiliary ring at the force-applying end, which is used to thread an auxiliary rope connected to an external force-applying component, so that the external force-applying component can apply force to the force-applying end of the lever.

[0014] For example, in at least one embodiment of the present invention, a hook device further includes: The hook is threadedly installed on the force-bearing end of the lever.

[0015] The beneficial effects of the embodiments of this utility model are as follows: In this invention, during the wire rope splicing operation, the operator first hooks the hook portion of the lever's force-bearing end onto the wire rope connected to the object to be lifted. Then, the operator presses down on the lever's force-applying end, causing it to rise axially around the rotation point of the sleeve. This lifts the hooked wire rope along with the force-bearing end. Once the force-bearing end is a certain height above the force-applying end, the wire rope, under its own weight, slides down the surface of the lever. The wire rope contacts and presses against the anti-detachment component, causing it to open and eventually slide into the hook. After the wire rope enters the hook, the anti-detachment component returns to its initial position under the elastic force of the torsion spring, re-abutting against the inner ring wall of the hook, forming a closed annular space. At this point, the wire rope is confined inside the hook and cannot detach, thus ensuring the safety and reliability of the splicing.

[0016] This device is simple and convenient to operate, requiring no complicated operating procedures. Through the cooperation of lever components and sleeves, and utilizing the lever principle, the operator only needs to apply a relatively small force at the force application end to lift a heavy wire rope. This eliminates the need for manual lifting of the wire rope, reducing labor intensity and safety risks caused by accidental slippage or loss of the wire rope. Attached Figure Description

[0026] like Figures 1-5 As shown, a hook device according to one embodiment of the present invention is used to hook a steel wire rope 2 connected to a load to be lifted into a hook 1. The device includes a sleeve 4 and a lever 5. The sleeve 4 is cylindrical, and its outer peripheral wall is used to rotatably connect with the side of the hook 1, ensuring that the sleeve 4 can rotate around the connection point and providing support for the swing of the lever 5. The lever 5 passes through the sleeve 4, and its two ends are the force-applying end and the force-receiving end, respectively. The force-receiving end is provided with a hook portion 501. An anti-detachment component 3 is hinged inside the hook 1, forming a closed annular space when it abuts against the inner annular wall of the hook 1, preventing the steel wire rope 2 from detaching. A torsion spring is installed at the hinge point of the anti-detachment component 3, and the two ends of the torsion spring act on the anti-detachment component 3 and the hook 1 respectively, causing the anti-detachment component 3 to abut against the inner annular wall of the hook 1.

[0027] Working Principle: During the wire rope 2 splicing operation, the operator first hooks the hook 501 of the force-bearing end of the lever 5 onto the wire rope 2 connected to the object to be lifted. Then, the operator presses down on the force-applying end of the lever 5, causing the force-bearing end to lift upwards around the rotation point of the sleeve 4, thereby lifting the hooked wire rope 2 as well. When the force-bearing end is higher than the force-applying end by a certain height, the wire rope 2 slides down the surface of the lever 5 under its own weight. The wire rope 2 will contact and squeeze the anti-detachment part 3, causing it to open, and finally slide into the hook 1. After the wire rope 2 enters the hook 1, the anti-detachment part 3 returns to its initial position under the elastic force of the torsion spring, and abuts against the inner ring wall of the hook 1 again, forming a closed annular space. At this time, the wire rope 2 is confined inside the hook 1 and cannot detach from the hook 1, thus ensuring the safety and reliability of the splicing.

[0028] This device is simple and convenient to operate, without the need for complicated operating procedures. Through the cooperation of lever 5 and sleeve 4, and by utilizing the lever principle, the operator only needs to apply a relatively small force at the force application end to lift the heavy wire rope 2. It eliminates the need for manual lifting of the wire rope 2, reducing labor intensity and safety risks caused by the wire rope 2 accidentally slipping or falling.

[0029] In some examples, such as Figures 2-4As shown, the cassette 6 is made of high-strength metal and is deformable. Its two ends can be connected via connecting components 7 to clamp onto the surface of the hook 1. A mounting plate 8 is located in the middle of the cassette 6, providing a mounting position for the sleeve 4. A rotating shaft 9 is provided on the outer peripheral wall of the sleeve 4, rotatably mounted on the mounting plate 8, allowing the sleeve 4 to rotate around the axis of the rotating shaft 9.

[0030] The connecting assembly 7 has two forms. The first form features a cylindrical internally threaded sleeve 701 at one end of the strap 6, and an externally threaded post 702 rotatably attached to the other end. During installation, the strap 6 is wrapped around the hook 1. By rotating the externally threaded post 702, it gradually screws into the internally threaded sleeve 701, causing the two ends of the strap 6 to gradually approach each other, thus tightly clamping the strap 6 onto the hook 1. The advantage of this connection method is its ease of operation; the strap 6 can be installed and removed simply by rotating the externally threaded post 702.

[0031] The second form of the connecting component 7 is as follows: both ends of the strap 6 are provided with connecting screw holes 704. During installation, the strap 6 is first wrapped around the hook 1, aligning the connecting screw holes 704 at both ends. Then, the connecting bolts 703 are screwed into the connecting screw holes 704 at both ends in sequence. By tightening the connecting bolts 703, the connection between the two ends of the strap 6 is achieved, thereby fixing the strap 6 to the hook 1. The advantage of this connection method is that it has high connection strength and can better withstand the force generated when the lever 5 is operated.

[0032] In some examples, such as Figure 4 , 5 As shown, two installation methods between lever 5 and sleeve 4 were designed.

[0033] The first installation method involves a through first locking pin hole 401 on the side wall of the sleeve 4, and multiple second locking pin holes 502 evenly distributed along the length of the lever 5, with the same diameter as the first locking pin hole 401. The locking pin 11 can pass through both the first locking pin hole 401 and the selected second locking pin hole 502 simultaneously.

[0034] Working principle: In actual operation, when it is necessary to fix the lever 5, the operator selects the appropriate position of the second locking pin hole 502 on the lever 5 according to actual needs. Then, the locking pin 11 is inserted into the first locking pin hole 401 and passes through the selected second locking pin hole 502, thereby fixing the lever 5 to the sleeve 4. By selecting different positions of the second locking pin hole 502, the position of the lever 5 relative to the sleeve 4 can be changed, thereby adjusting the length of the lever arm. This allows the device to adapt to different lifting operation scenarios, improving the versatility and practicality of the device.

[0035] The second installation method: the outer peripheral wall of the lever 5 is machined with external threads, and the inner wall of the sleeve 4 is machined with internal threads that match the external threads of the lever 5, so as to ensure that the lever 5 can be threadedly connected in the sleeve 4.

[0036] Working principle: When lever 5 needs to be installed, the operator rotates lever 5 so that its external thread gradually engages with the internal thread of the sleeve 4. As the rotation continues, lever 5 gradually enters the sleeve 4, and the position of lever 5 within the sleeve 4 can be adjusted by controlling the number of rotations, thereby adjusting the lever arm length. This allows the device to adapt to different lifting operation scenarios, improving its versatility and practicality.

[0037] In some examples, such as Figure 1 As shown, anti-slip texture 503 is designed on the surface of the force-applying end of the lever 5. When the operator manually operates the lever 5, the hand contacts the surface of the force-applying end, increasing the friction between the hand and the force-applying end. This allows for a more stable grip on the force-applying end of the lever 5, preventing operational errors caused by hand slippage and ensuring the safety and accuracy of the hooking process.

[0038] An auxiliary ring 504 is provided at the force-applying end of the lever 5. When dealing with a heavy wire rope 2, and manual operation of the lever 5 is laborious, the operator can thread the auxiliary rope through the auxiliary ring 504 and tie a knot to connect the auxiliary rope to the auxiliary ring 504. The other end of the auxiliary rope is connected to an external force-applying device (such as a winch). The external force-applying device applies tension to the force-applying end of the lever 5 through the auxiliary rope, replacing manual operation. The hook part 501 is threaded onto the force-bearing end of the lever 5, facilitating installation and disassembly and improving the maintainability of the device.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
