[0002] Steel structures are structures made of steel materials and are one of the main types of building structures. Due to their light weight and ease of construction, steel structures are widely used in large factories, stadiums, and high-rise buildings. I-beams are a common type of steel structure, and lifting equipment is needed to assist workers in completing the installation process.

[0003] As a crucial lifting tool in lifting operations, the hook bears the core task of connecting heavy objects to lifting equipment. However, most hooks are currently fixed using the traditional method of bolts and connectors. During the disassembly and assembly process, workers must use specific tools to tighten each bolt one by one in order to remove or reinstall the hook. This makes it extremely inconvenient and inefficient when the hook needs to be disassembled and maintained. Utility Model Content

[0004] The purpose of this utility model is to provide a lifting tool for steel structure installation, so as to solve the problem mentioned in the background art that most current lifting hooks are fixed with bolts and connectors, and workers need to use specific tools to tighten the bolts one by one during disassembly and assembly, which is extremely inconvenient and reduces efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a lifting device for steel structure installation, comprising a box body, a mounting base engaged at the bottom of the box body, a hook rotatably mounted at the bottom end of the mounting base, two insert rods symmetrically slidably mounted inside the box body, insertion holes for insertion and engagement of the insert rods on both sides of the mounting base, a spring sleeved on the surface of the insert rod, an inclined block slidably mounted at the end of the insert rod, an inclined groove for sliding engagement of the inclined block on the surface of the insert rod, a support rod fixed between the two inclined blocks, and a support component for supporting the inclined blocks at the middle of the support rod.

[0006] As a preferred embodiment of this utility model, a mounting frame is fixedly provided at the top of the box, and both sides of the mounting frame are provided with moving grooves that cooperate with the movement of the support rod. A lifting ring is fixedly provided at the middle of the top of the mounting frame.

[0007] As a preferred embodiment of this utility model, a limiting block is fixedly provided at the bottom end of the inclined block, and the size of the inclined groove is larger than the size of the inclined block.

[0008] As a preferred technical solution of this utility model, a limiting ring is fixedly provided on the surface of the insertion rod, one end of the spring is fixedly connected to one side of the limiting ring, and the other end is fixedly connected to the inner wall of the box.

[0009] As a preferred technical solution of this utility model, the support component includes a circular plate, which is fixedly installed in the middle of the support rod. A guide post is slidably provided in the middle of the circular plate, and the bottom end of the guide post is fixedly connected to the middle of the top of the box. A pressing plate is fixedly provided on one side of the circular plate.

[0010] As a preferred embodiment of this utility model, the surface of the pressing plate is provided with a plurality of evenly spaced anti-slip grooves, and the top of the guide post is fixedly provided with a limiting cap.

[0011] As a preferred embodiment of this utility model, a second spring is sleeved on the surface of the guide column, the bottom end of the second spring is fixedly connected to the top end of the box, and the top end is fixedly connected to the bottom end of the circular plate.

[0012] As a preferred technical solution of this utility model, the inside of the box is provided with a slot that engages with the card seat, and the card seat and the slot are engaged and connected.

[0013] Compared with related technologies, the lifting device for steel structure installation provided by this utility model has the following advantages:

[0014] The designed support components provide stable support for the inclined block and simultaneously drive the support rod and inclined block to move precisely in the vertical direction. As the inclined block moves, the inclined groove that slides with it guides the insertion rod to move synchronously in the horizontal direction, allowing the insertion rod to smoothly retract into the housing. At this point, the card holder is precisely engaged with the corresponding position in the housing. Then, the support rod is released, and under the combined action of the spring and the restoring force of the support components, the insertion rod can be quickly and accurately inserted into the preset insertion hole of the card holder, achieving a stable insertion limit and thus limiting the hook position. This greatly facilitates the subsequent installation and disassembly of the hook and significantly improves work efficiency. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-6 This utility model provides a lifting device for steel structure installation, including a box body 1. A mounting base 2 is fitted into the bottom of the box body 1. A hook 3 is rotatably mounted on the bottom end of the mounting base 2. Two insert rods 4 are symmetrically slidably mounted inside the box body 1. Insertion holes for insertion into the insert rods 4 are provided on both sides of the mounting base 2. A spring 7 is fitted onto the surface of the insert rod 4. An inclined block 5 is slidably mounted at the end of the insert rod 4. An inclined groove 6 is provided on the surface of the insert rod 4 to slidably engage with the inclined block 5. A support rod 8 is fixed between the two inclined blocks 5. A support assembly 9 for supporting the inclined blocks 5 is provided in the middle of the support rod 8. Component 9 supports the inclined block 5 and moves the support rod 8 and the inclined block 5 vertically. The movement of the inclined block 5, combined with the sliding groove 6, moves the insertion rod 4 horizontally, causing it to retract into the housing 1. By engaging the card seat 2 into the housing 1, the support rod 8 is released. Under the return of the spring 7 and the support component 9, the insertion rod 4 quickly engages with the insertion hole at the card seat 2, facilitating the subsequent installation and removal of the hook 3 and improving work efficiency.

[0024] The support assembly 9 includes a circular plate 901, which is fixedly installed in the middle of the support rod 8. A guide post 902 is slidably provided in the middle of the circular plate 901. The bottom end of the guide post 902 is fixedly connected to the middle of the top of the box 1. A pressing plate 905 is fixedly provided on one side of the circular plate 901. Several evenly spaced anti-slip grooves are opened on the surface of the pressing plate 905. A limit cap 904 is fixedly provided at the top of the guide post 902. A second spring 903 is sleeved on the surface of the guide post 902. The bottom end of the second spring 903 is fixedly connected to the top of the box 1, and the top end is fixedly connected to the bottom end of the circular plate 901. The support assembly 9 can provide vertical support for the support rod 8 and the two inclined blocks 5. The pressing plate 905 can drive the circular plate 901 to move in the vertical direction, thereby driving the support rod 8 and the two inclined blocks 5 to move in the vertical direction.

[0025] A limiting ring 10 is fixedly provided on the surface of the insertion rod 4. One end of the spring 7 is fixedly connected to one side of the limiting ring 10, and the other end is fixedly connected to the inner wall of the box 1. The limiting ring 10 can support and fix the spring 7, so that the spring 7 can play a supporting and limiting role for the insertion rod 4.

[0026] A limiting block 11 is fixed at the bottom of the inclined block 5. The size of the inclined groove 6 is larger than the size of the inclined block 5. The limiting block 11 can limit the movement of the inclined block 5 and prevent the inclined block 5 from leaving the inclined groove 6. Since the size of the inclined groove 6 is larger than the size of the inclined block 5, the movement of the inclined block 5 can drive the insertion rod 4 to move in the horizontal direction.

[0027] The interior of the housing 1 has a slot that engages with the card holder 2, and the card holder 2 and the card slot are connected by an engagement. The card holder 2 and the card slot are provided to limit the engagement of the card holder 2 and serve as a guide.

[0028] The top of the housing 1 is fixedly provided with a mounting bracket 12, and both sides of the mounting bracket 12 are provided with moving grooves that cooperate with the movement of the support rod 8. The middle of the top of the mounting bracket 12 is fixedly provided with a lifting ring 13. The mounting bracket 12 and the lifting ring 13 can support and fix the lifting ring 13, which is convenient for installation and use with the lifting rope. The moving grooves allow the support rod 8 to move without any restriction.

[0029] When using the hook 3, the operation is simple and efficient. Simply press down the preset pressing plate 905. As the pressing plate 905 moves vertically downwards, the circular plate 901 moves steadily vertically along the surface of the guide post 902. This movement simultaneously causes the support rod 8 and the two connected inclined blocks 5 to move vertically. At this time, the spring 903 is compressed due to the force. When the two inclined blocks 5 move vertically, the two insert rods 4 can move horizontally in opposite directions through the inclined groove 6 that slides with them, allowing the insert rods 4 to engage with the card seat 2. The insertion holes gradually separate, creating conditions for the separation of the card holder 2 from the housing 1, allowing the hook 3 to be quickly disassembled for regular maintenance. When the maintenance is completed and the hook 3 needs to be reinstalled, simply repeat the above steps, inserting the maintained hook 3 back into the housing 1 via the card holder 2, then releasing the pressing plate 905. Under the reset action of spring 7 and spring 903, the insertion rod 4 will quickly and tightly insert into the insertion hole on the card holder 2, thus completing the secure installation of the hook 3. This simplifies the disassembly and assembly process of the hook 3 and greatly improves work efficiency.
