Description

Technical Field

[0001] This utility model relates to the field of steel structure production technology, and in particular to an auxiliary lifting device for steel structure components. Background Technology

[0002] Steel structural components are made by cutting steel plates to size and then welding them together. Due to their light weight, high strength, and fast construction speed, they are very suitable for building structures with large spans and column spacings. Therefore, steel structures are important supporting components for factory construction and bridge engineering, and have high reliability.

[0003] In the production of steel structures, the main process involves welding cut steel plates, such as I-beams. Specialized clamps are typically used for fixing and welding before assembly. However, for other unconventional structures, workers usually perform manual welding on scaffolds. Therefore, the handling and height adjustment of steel structural components significantly impact production efficiency, especially since the components are relatively heavy and moving them is generally done using electric hoists, which is inefficient. To address these issues, we propose an auxiliary lifting device for steel structural components. Utility Model Content

[0004] This application provides an auxiliary lifting device for steel structural components, which solves the problem of inconvenient handling of steel structural components, resulting in low production efficiency in steel structures.

[0005] This application provides an auxiliary lifting device for steel structural components, including a support platform, universal wheels installed at the bottom of the support platform, a push rod installed on one side of the support platform, an adjustment platform installed on the support platform via a lifting bracket, an adjustment structure for adjusting the lifting bracket provided on the support platform, a support frame fixed on the adjustment platform, and multiple rollers provided on the support frame; it also includes a roller limiting structure.

[0006] Preferably, the adjustment structure includes a slide groove disposed on the support platform and the adjustment platform. One side of the lifting bracket slides in the slide groove via a moving rod. A moving block is sleeved on one of the moving rods, and a screw is threaded onto the moving block. Both ends of the screw are rotatably mounted on the support platform, and a drive mechanism is provided at one end of the screw.

[0007] Preferably, the driving mechanism is a motor mounted on the support platform, and the motor is connected to the screw.

[0008] Preferably, the driving mechanism is a handle.

[0009] Preferably, the limiting structure includes a crossbar and two pull rods rotatably connected to the crossbar. A limiting block is fixed to the end of the pull rod, and the limiting block is provided with a groove corresponding to the roller. An adjusting rod is threaded onto the crossbar.

[0010] Preferably, the two ends of the adjusting rod are respectively provided with an abutment block and a turntable.

[0011] Preferably, a connector is also provided on one side of the support platform, and a connecting frame is installed on both the connector and the support platform, with the push rod flexibly hinged to the connecting frame.

[0012] Preferably, the push rod is provided with a handle.

[0013] Preferably, the support platform and the adjustment platform are welded together from square tubing.

[0014] As can be seen from the above technical solution, this application provides an auxiliary lifting device for steel structure components. When using this application, the application is lowered to a low position and moved under the frame where the steel structure is placed. Then, the adjusting structure raises the lifting bracket until the support of the steel structure falls onto the application. Then, the steel structure to be processed or moved is moved to the designated location. When the steel structure component is long, multiple applications can be used together to lift one steel structure component. When moving the steel structure, after moving it to the designated location, the steel structure component can be lowered by adjusting the structure. If it is necessary to move it to a designated position and height and fix it to other steel structure components, the lifting bracket can be adjusted to any height within the height range to facilitate correspondence with other steel structure components, and then welding or fixing with bolts can be performed.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. With the support platform and casters, this application can be moved at any angle within the factory, facilitating movement at complex angles and making it easy to use;

[0017] 2. The push rod design facilitates the movement of this application, further improving the ease of movement of this application;

[0018] 3. By setting up the adjustment platform and adjustment structure, this application can be adjusted to the required height, which facilitates its movement under the steel structure for further operations;

[0019] 4. By setting up a limiting structure and rollers, steel structural components can be restricted on the rollers, thereby improving the stability of the movement process. Furthermore, it also makes it easier for the steel structural components to move on the rollers, improving the convenience of use.

[0020] In summary, this application allows steel structural components to be moved or adjusted to different heights for welding or bolting. The operation is simple and convenient, and the components can be moved from any angle, thus providing high flexibility and improving the processing efficiency of steel structures.

Detailed Implementation

[0027] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0028] See Figure 1-4 An auxiliary lifting device for steel structural components is disclosed. This application is used for the auxiliary handling and lifting of steel structural components. It includes a support platform 1, which is welded from square tubing. The bottom of the support platform 1 is equipped with casters 2, which can move freely in the horizontal direction. This facilitates the handling and / or lifting and fixing of the steel structural components by adjusting them to a suitable angle. Correspondingly, a push rod 8 is also installed on one side of the support platform 1. The push rod 8 can assist in the movement of this application. Furthermore, a handle 12 is provided on the push rod 8. When moving this application, the user can push or pull the application by the handle 12, and can also turn it by the push rod 8, thereby improving the operation performance of this application.

[0029] An adjustment platform 5 is installed on the support platform 1 via a lifting bracket 4. The adjustment platform 5 is made of welded square tubing. The lifting bracket 4 is a scissor-fork lifting structure. The adjustment range of this application is 35-75cm, which can be used for movement between various steel structure support frames. The adjustment platform 5 is adjusted through the lifting bracket 4. The support platform 1 is provided with an adjustment structure for adjusting the lifting bracket 4. Through the adjustment structure, the adjustment platform 5 can be adjusted to any height within the adjustment range, which is convenient for fixing the steel structure components. A support frame 6 is fixed on the adjustment platform 5. Multiple rollers 7 are provided on the support frame 6. This application is supported by the rollers 7. The feature of this structure is that it is convenient for the retraction and adjustment of the steel structure, thereby improving the flexibility of this application. Furthermore, in order to ensure the stability of the steel structure components on the rollers 7, this application also includes a roller 7 limiting structure, which is used to restrict the movement of the steel structure components on the rollers 7, making the movement process safer and more convenient.

[0030] In this utility model, the adjustment structure includes a slide groove 3 set on the support platform 1 and the adjustment platform 5. The slide groove 3 can be processed by stamping or cutting. One side of the lifting bracket 4 slides in the slide groove 3 via a moving rod 13. The moving rod 13 supports the lifting bracket 4 and adjusts the height of the lifting bracket 4 by sliding in the slide groove 3. Specifically, during adjustment, a moving block 16 is sleeved on one of the moving rods 13, and a screw 15 is threaded on the moving block 16. The rotation of the screw 15 drives the moving block 16 to move, thereby adjusting the height of the lifting bracket 4 through the moving rod 13. The screw 15 can be used to adjust the lifting bracket 4 to any height within the adjustment range. Both ends of the screw 15 are rotatably mounted on the support platform 1, and one end of the screw 15 is provided with a drive mechanism for driving the screw 15 to rotate.

[0031] In some embodiments, the driving mechanism is a motor 14 mounted on the support platform 1. The motor 14 is connected to the screw 15. In this embodiment, the motor 14 controls the rotation of the screw 15. The control point can be set on the push rod 8, and the lifting and lowering of the lifting bracket 4 can be controlled at will.

[0032] In some embodiments, the drive mechanism is a handle 11. This embodiment can control the adjustment of the lifting bracket 4 without carrying a power supply, making it more flexible to use.

[0033] In this utility model, the limiting structure includes a crossbar 18 and two pull rods 17 rotatably connected to the crossbar 18. The pull rods 17 can rotate, and a limiting block 19 is fixed to the end of the pull rod 17. The limiting block 19 is provided with a groove corresponding to the roller 7. The limiting block 19 is inserted into the bottom of the roller 7 through the gap of the roller 7, and then the pull rod 17 is rotated so that the groove corresponds to the roller 7 and the groove is stuck on the roller 7. An adjusting rod 20 is threaded onto the crossbar 18. Rotating the adjusting rod 20 abuts against the steel structure to fix the steel structure. It can abut against the roller 7. The limiting structure is placed at the edge of the roller 7 and used as a guardrail. When fixed, since the pull rod 17 can rotate, the limiting structure can be set horizontally or vertically to the roller 7. When adjusting the adjusting rod 20, abutting blocks and a turntable are respectively provided at both ends of the adjusting rod 20. The abutting blocks are used to abut against the steel structure, and the turntable is used to rotate the adjusting rod 20.

[0034] In this utility model, a connector 10 is also provided on one side of the support platform 1. A connecting frame 9 is installed on both the connector 10 and the support platform 1 to improve the reliability of the connection between the push rod 8 and the support platform 1. The push rod 8 is flexibly hinged on the connecting frame 9, which allows the push rod 8 to be adjusted to different angles for handling.

[0035] As can be seen from the above technical solution, when this application is used, it is lowered to a low position and moved to the frame under which the steel structure is placed. Then, the adjusting structure raises the lifting bracket 4 until the support of the steel structure falls on this application. Then, the steel structure to be processed or moved is moved to the designated location. When the steel structure is long, multiple applications can be used together to lift one steel structure. When moving the steel structure, after moving it to the designated location, the steel structure can be lowered by adjusting the structure. If it is necessary to move it to a designated position and height and fix it to other steel structures, the lifting bracket 4 can be adjusted to any height within the height range to facilitate correspondence with other steel structures, and then welding or fixing with bolts can be performed.
