Abstract
Description
Technical Field
[0001] This utility model relates to the field of hoisting devices, specifically to a hoisting device for steel structure components. Background Technology
[0002] Steel structure component hoisting equipment is a specialized system used in construction, bridge, and industrial plant projects to safely and efficiently hoist prefabricated steel structure components (such as steel beams, steel columns, trusses, and space frames) from the ground or transport vehicles to designated installation locations, and to temporarily fix or permanently connect them. Its core function is to address the challenges of large weight, long dimensions, complex shapes, and high installation precision requirements of steel structure components, ensuring a safe and controllable hoisting process, high construction efficiency, and no damage to the components.
[0003] A search revealed a utility model for hoisting high-altitude cantilevered steel structure components, with publication number CN217650703U. This device includes a balance beam and four hoisting mechanisms, all located below the balance beam. Each hoisting mechanism comprises a first connecting block, a lead screw, a second connecting block, hooks, and limiting blocks. The lead screw is fixedly installed on the lower end face of the first connecting block, and a connecting hole is provided on the upper end face of the second connecting block. This utility model, by incorporating the lead screw, second connecting block, multiple hooks, and limiting blocks, allows the device to restrict the range of motion of the second connecting block via the limiting blocks, preventing it from slipping off the lead screw and falling off. The four hooks on the lower end face of the second connecting block allow for internal, external, and side-hanging of the component. The height of the hooks can be adjusted by rotating the second connecting block, simplifying the adjustment process and improving efficiency.
[0004] In the above comparative cases, the hoisting device for the high-altitude cantilevered steel structure components simply uses four hooks to hoist the steel structure components. However, none of the four hooks have an anti-detachment function, which may lead to the risk of falling during transportation, making the hoisting device a certain safety hazard.
[0005] Therefore, it is necessary to invent a steel structure component hoisting device to solve the above problems. Utility Model Content
[0006] The purpose of this utility model is to provide a steel structure component hoisting device. By hooking the hook onto the steel structure component, and then moving the handle outside the hook to extend and retract the sliding buckle from inside the hook, the steel wire rope and the lower fixing block are pulled. The weight of the steel structure component itself pulls the connecting seat inside the hook and the fixing block downwards. During this movement, the connecting seat moves outside the fixing rod, leaving space. At this time, the second spring inside the sliding buckle rebounds, pushing the limiting block into the space inside the connecting seat, locking the sliding buckle inside the hook and preventing it from detaching. This solves the problem in the aforementioned comparative case of high-altitude suspended steel structure component hoisting devices, which simply hoist the steel structure component using four hooks, none of which have anti-detachment functionality. This leads to the risk of falling during transport, creating a safety hazard in the hoisting device.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a steel structure component hoisting device, including a hoisting bracket for supporting the hoisting device;
[0008] A drive motor is fixedly installed on the outside of the hoisting bracket. A winder is fixedly connected to the output end of the drive motor. A steel wire rope is wound around the outside of the winder. A servo motor is fixedly installed on the right side of the hoisting bracket. A threaded rod is fixedly connected to the output end of the servo motor. A movable seat is threadedly connected to the outside of the threaded rod. A traction wheel is rotatably connected inside the movable seat.
[0009] A fixing block is fixedly connected to the other end of a steel wire rope. A fixing rod is fixedly connected inside the fixing block, and a connecting seat is slidably connected to the outside of the fixing rod. A damping spring is fixedly installed below the connecting seat and is located inside the fixing block. A hook is fixedly connected below the connecting seat, and a sliding buckle is slidably connected inside the hook. A handle is fixedly installed on the outside of the sliding buckle. An installation groove is opened on the upper outer side of the sliding buckle, and a second spring is fixedly installed inside the installation groove. A limit block is fixedly connected to the upper end of the second spring.
[0010] Preferably, one end of the winding device is fixedly connected to a first spur gear, one side of the first spur gear is meshed with a second spur gear, and the second spur gear is fixedly connected to another set of winding devices.
[0011] Preferably, the external threads of the threaded rod are tapped in the opposite direction, and the wire rope is hung outside the traction wheel.
[0012] Preferably, sliding rods are slidably connected to the lower two sides of the movable seat, and the sliding rods are fixedly connected to the inner side of the hoisting bracket.
[0013] Preferably, the connecting seat is slidably connected to the fixing block, and the connecting seat is hollow inside.
[0014] Preferably, the outer side of the hook is provided with a sliding groove, the handle is located inside the sliding groove, and the handle is slidably connected to the hook.
[0015] The technical effects and advantages provided by this utility model in the above technical solution are as follows:
[0016] This invention utilizes a fixed block, a fixed rod, a connecting seat, a hook, a sliding buckle, a handle, a second spring, and a limiting block. The weight of the steel structure component itself locks the sliding buckle and hook in place, preventing detachment. The hook is attached to the steel structure component. Then, the handle outside the hook is moved, causing the sliding buckle to slide out of the hook. Next, the steel wire rope and the lower fixed block are pulled, and the weight of the steel structure component pulls the connecting seat inside the hook and fixed block downwards. During this movement, the connecting seat moves outside the fixed rod, creating space. At this point, the second spring inside the sliding buckle rebounds, pushing the limiting block into the space inside the connecting seat, locking the sliding buckle inside the hook and preventing detachment.

Detailed Implementation
[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0027] This utility model provides, for example Figure 1-6 The steel structure component hoisting device shown includes a hoisting bracket 1 for supporting the hoisting device;
[0028] A drive motor 2 is fixedly installed on the outside of the hoisting bracket 1. A winder 3 is fixedly connected to the output end of the drive motor 2. A wire rope 6 is wound around the outside of the winder 3. A servo motor 7 is fixedly installed on the right side of the hoisting bracket 1. A threaded rod 8 is fixedly connected to the output end of the servo motor 7. A movable seat 9 is threadedly connected to the outside of the threaded rod 8. A traction wheel 10 is rotatably connected inside the movable seat 9.
[0029] A fixing block 12 is fixedly connected to the other end of the wire rope 6. A fixing rod 13 is fixedly connected inside the fixing block 12. A connecting seat 14 is slidably connected to the outside of the fixing rod 13. A damping spring 15 is fixedly installed below the connecting seat 14 and is located inside the fixing block 12. A hook 16 is fixedly connected below the connecting seat 14. A sliding buckle 18 is slidably connected inside the hook 16. A handle 19 is fixedly installed on the outside of the sliding buckle 18. An installation groove 20 is opened on the upper outer side of the sliding buckle 18. A second spring 21 is fixedly installed inside the installation groove 20. A limit block 22 is fixedly connected to the upper end of the second spring 21.
[0030] like Figure 1 , Figure 2 and Figure 3 As shown, a first spur gear 4 is fixedly connected to one end of the winding device 3, and a second spur gear 5 is meshed with one side of the first spur gear 4. The second spur gear 5 is fixedly connected to another set of winding devices 3. By turning on the switch of the drive motor 2, the winding device 3 is driven to rotate. The first spur gear 4 at one end of the winding device 3 and the second spur gear 5 on the other side mesh and drive the two sets of winding devices 3 to rotate relative to each other and pull the wire rope 6.
[0031] like Figure 1 and Figure 2As shown, the external threads of the threaded rod 8 are tapped in opposite directions, and the wire rope 6 is hung outside the traction wheel 10. By turning on the servo motor 7, the threaded rod 8 is driven to rotate. By using the opposite tapping of the external threads of the threaded rod 8, the two sets of moving seats 9 and the traction wheel 10 are driven to move closer or further apart, thereby adjusting the distance between the two sets of wire ropes 6.
[0032] like Figure 2 As shown, sliding rods 11 are slidably connected to the lower sides of the movable seat 9. The sliding rods 11 are fixedly connected to the inner side of the hoisting bracket 1. When the movable seat 9 moves through the threaded rod 8, the sliding rods 11 improve the stability of the movable seat 9 during the movement process.
[0033] like Figure 4 and Figure 5 As shown, the connecting seat 14 is slidably connected to the fixing block 12. The connecting seat 14 is hollow inside. When the weight of the steel structure component pulls the hook 16 and the connecting seat 14, the connecting seat 14 slides outside the fixing rod 13 and compresses the damping spring 15, leaving a reserved space between the connecting seat 14 and the fixing rod 13 so that the subsequent limiting block 22 can extend and retract into the space to lock the sliding buckle 18 and the hook 16.
[0034] like Figure 4 and Figure 5 As shown, a groove 17 is provided on the outer side of the hook 16, and the handle 19 is located inside the groove 17. The handle 19 is slidably connected to the hook 16. By pulling the handle 19 inside the groove 17 on the outer side of the hook 16, the handle 19 causes the sliding buckle 18 to slide out of the hook 16.
[0035] The working principle of this utility model is as follows: First, connect the external power supply. Then, use a crane to move the lifting support 1, allowing the hooks 16 on both sides below the lifting support 1 to move above the steel structure component. Next, depending on the length of the steel structure component, turn on the servo motor 7 switch on the outside of the lifting support 1, driving the threaded rod 8 to rotate. The rotation of the threaded rod 8 causes the moving seats 9 on both sides and the traction wheels 10 to move closer or further apart, thereby adjusting the length of the steel structure component. Next, hang the hook 16 on the steel structure component. Then, pull the handle 19 inside the sliding groove 17 on the outside of the hook 16, causing the handle 19 to drive the sliding buckle 18 to slide out of the hook 16. Insert the front end of the sliding buckle 18 into the other end of the hook 16, thereby locking the steel structure component. Next, turn on the drive motor 2 switch, driving the winding device 3 to rotate. Utilizing the meshing transmission between the first spur gear 4 at one end of the winding device 3 and the second spur gear 5 on the other side, the two sets of winding devices 3 rotate relative to each other, pulling the wire rope 6, the hook 16, and the steel structure component. The weight of the steel structure component itself acts as the load. When the hook 16 is pulled and the connecting seat 14 is moved, the connecting seat 14 slides outside the fixed rod 13 and compresses the damping spring 15, leaving a reserved space between the connecting seat 14 and the fixed rod 13. At this time, the second spring 21 inside the sliding buckle 18 rebounds and pushes the limiting block 22 into the space inside the connecting seat 14, locking the sliding buckle 18 inside the hook 16, thus preventing it from slipping off. Later, when the steel structure component is placed on the ground, the hook 16 will lose the weight of the steel structure component, and the weight will be released through the space below the connecting seat 14. The damping spring 15 rebounds, causing the connecting seat 14 to extend and retract outside the fixed rod 13, so that the space inside the connecting seat 14 is filled by the fixed rod 13, squeezing the limiting block 22. This causes the limiting block 22 to squeeze the second spring 21 and extend into the sliding buckle 18, releasing the lock between the hook 16 and the sliding buckle 18. At this time, pulling the handle 19 can move the sliding buckle 18 into the hook 16. Finally, the steel structure component is taken out from the hook 16. This completes the use of the steel structure component hoisting device.
[0036] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
