Description

Technical Field

[0001] This utility model relates to the technical field of steel truss lifting devices, specifically a multi-functional lifting device for extra-large span vertical turning steel trusses. Background Technology

[0002] As is well known, lifting is a crucial step in the construction of extra-large span vertical turning steel trusses. When lifting such trusses, the angle of the clamping device needs to be precisely adjusted according to the specific working environment and truss structure. Traditional methods rely on manual adjustment, which is not only inefficient but also makes it difficult to guarantee the optimal clamping angle each time. Errors during manual adjustment can lead to insecure or misaligned clamping, increasing construction risks. To maintain the stability of the clamping mechanism in the required position, a reliable locking mechanism is needed. Traditional locking methods typically rely on the simple locking function built into the drive motor. However, this method performs poorly under high working pressure and can easily damage mechanical components. Long-term use of the simple locking function may also affect the lifespan of the drive motor itself, as it is not designed to withstand high pressure for extended periods. For these reasons, operators face certain safety risks when performing these tasks. For example, during manual adjustment of the clamping angle, accidental movement or insecure fixing can lead to equipment malfunction, causing personal injury or property damage. Furthermore, manual adjustment and simple locking mechanisms limit overall work efficiency. Each adjustment takes a considerable amount of time, and frequent manual intervention slows down the overall project schedule. Therefore, it is necessary to propose a solution to this technical problem. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this utility model provides a multi-functional lifting device for extra-large span vertical turning steel trusses.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a multi-functional lifting device for extra-large span vertical turning steel trusses, comprising an installation plate, a clamping mechanism on the installation plate, a first telescopic mechanism and an installation box at the top of the installation plate, a slot at the top of the installation box, a bearing seat on the slot, a hydraulic lifter on the bearing seat, a steel strand on the hydraulic lifter, a drive motor inside the installation box, the output end of the drive motor connected to the hydraulic lifter and provided with a gear, the output end of the first telescopic mechanism extending into the interior of the installation box and provided with a push plate, one end of the push plate being provided with a toothed block, the toothed block meshing against the gear.

[0005] Furthermore, the present invention is improved in that the clamping mechanism includes a rectangular groove and a second telescopic mechanism. The rectangular groove is formed at the bottom end of the mounting plate. The second telescopic mechanism is installed on both sides of the mounting plate and extends into the rectangular groove. A rectangular plate is provided between the output end of the second telescopic mechanism and the rectangular groove. A lifting groove is formed on one side of the rectangular plate. A clamping frame is provided on the lifting groove. A lifting mechanism is provided between the clamping frame and the lifting groove. A clamping plate is provided at the bottom end of the clamping frame and the bottom end of the rectangular plate.

[0006] Furthermore, the present invention is improved in that the lifting mechanism includes a lead screw, a threaded hole, and an adjusting motor. The lead screw is located in the lifting groove, the adjusting motor is installed inside the rectangular plate, the output end of the adjusting motor is connected to the lead screw, the threaded hole is opened on the clamping frame, the lead screw passes through the threaded hole, and a heat dissipation mechanism is provided on the rectangular plate.

[0007] Furthermore, the present invention is improved in that the heat dissipation mechanism includes heat dissipation holes, which are opened on one side of the rectangular plate, and multiple heat dissipation holes are provided.

[0008] Furthermore, the present invention is improved in that a fastening groove is provided on one side of the rectangular groove, an iron plate is provided on the fastening groove, and an electromagnet is provided between the rectangular plate and the fastening groove.

[0009] Furthermore, the present invention is improved in that both the first telescopic mechanism and the second telescopic mechanism are hydraulic rods.

[0010] Furthermore, an improvement of this utility model is that both the drive motor and the regulating motor are servo motors.

[0011] Compared with the prior art, this utility model provides a multi-functional lifting device for extra-large span vertical turning steel trusses, which has the following beneficial effects:

[0012] This multi-functional lifting device for extra-large span vertical turning steel trusses uses a first telescopic mechanism on the mounting plate to push a push plate, causing the gear block to disengage from the gear. The drive motor then adjusts the angle of the hydraulic lifter, allowing the mounting plate to be adjusted on the hydraulic lifter. This allows for flexible and accurate adjustment of the clamping mechanism's angle according to actual needs, ensuring precise alignment and clamping of the extra-large span vertical turning steel truss, thus improving operational precision. When locking the angle between the mounting plate and the hydraulic lifter is required, the output end of the first telescopic mechanism extends, pushing the push plate to re-engage the gear block, achieving hardware-level locking. This is more robust and reliable than traditional methods relying on the simple locking function of the drive motor, effectively preventing damage caused by excessive pressure, extending equipment lifespan, and reducing the need for manual intervention and safety risks during manual adjustments. The stable locking mechanism ensures no accidental movement during lifting operations, further guaranteeing operational safety and significantly improving work efficiency.

[0018] 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.

[0019] Please see Figures 1-4This utility model relates to a multi-functional lifting device for extra-large span vertical turning steel trusses, comprising a mounting plate 1, a clamping mechanism on the mounting plate 1, a first telescopic mechanism 2 and a mounting box 3 at the top of the mounting plate 1, a slot at the top of the mounting box 3, a bearing seat 4 on the slot, a hydraulic lifter 5 on the bearing seat 4, and steel strands 6 on the hydraulic lifter 5. A drive motor 7 is located inside the mounting box 3, and the output end of the drive motor 7 is connected to the hydraulic lifter 5 and is equipped with a gear 8. The first telescopic mechanism... The output end of the first telescopic mechanism 2 extends into the interior of the mounting box 3 and is provided with a push plate 9. One end of the push plate 9 is provided with a toothed block 10, which meshes against the gear 8. In this embodiment, by using the output end of the first telescopic mechanism 2 in the mounting box 3 to linearly move the push plate 9, the push plate 9 drives the toothed block 10 to move, and the toothed block 10 disengages from the gear 8. Then, the output end of the drive motor 7 is turned on to rotate the gear 8 and the hydraulic indicator. The hydraulic lifter 5 is stably fixed to the mounting box 3 through the bearing seat 4 and rotates, thereby adjusting the angle of the mounting plate 1, thereby adjusting the clamping machine. The angle of the clamping mechanism facilitates alignment of the clamping mechanism with the extra-large span vertical turning steel truss. The clamping mechanism then holds the extra-large span vertical turning steel truss. When the angle between the mounting plate 1 and the hydraulic lifter 5 needs to be locked, the output end of the first telescopic mechanism 2 extends, causing the push plate 9 to move the toothed block 10. The toothed block 10 meshes with the gear 8, thus locking the output end of the drive motor 7 and locking the angle of the mounting plate 1. The hydraulic lifter 5 and steel strand 6 are then used to lift the extra-large span vertical turning steel truss held by the clamping mechanism. By flexibly adjusting the angle of the clamping mechanism on the mounting plate 1, the extra-large span vertical turning steel truss can be flexibly clamped, solving the problem that traditional lifting equipment requires manual adjustment during angle adjustment, which poses a certain safety risk. Furthermore, the cooperation between the toothed block 10 and the gear 8 achieves hardware-fixed locking of the output end of the drive motor 7, solving the problems of the traditional locking method, which only uses the simple locking function of the drive motor 7, affecting the service life of the drive motor 7 and easily causing damage under pressure.

[0020] To achieve automatic clamping, in this design, the clamping mechanism includes a rectangular groove 11 and a second telescopic mechanism 12. The rectangular groove 11 is formed at the bottom end of the mounting plate 1. The second telescopic mechanism 12 is mounted on both sides of the mounting plate 1 and extends into the rectangular groove 11. A rectangular plate 13 is provided between the output end of the second telescopic mechanism 12 and the rectangular groove 11. A lifting groove is formed on one side of the rectangular plate 13, and a clamping frame 14 is provided on the lifting groove. A lifting mechanism is provided between the clamping frame 14 and the lifting groove. Clamping plates 15 are provided at the bottom end of the clamping frame 14 and the bottom end of the rectangular plate 13. By controlling the output end of the second telescopic mechanism 12 to move the rectangular plate 13 linearly, the two rectangular plates 13 can be adjusted. The spacing between the two clamping plates 15 is adjusted to facilitate the adjustment of the dimensions of the extra-large span vertical turning steel truss. Then, one end of the extra-large span vertical turning steel truss is positioned between the two clamping plates 15. The lifting mechanism can be used to move the clamping frame 14 upward, and the clamping plates 15 on the clamping frame 14 can be moved upward to approach the clamping plates 15 of the rectangular plate 13, thereby clamping the extra-large span vertical turning steel truss and realizing automatic clamping operation. This saves the inconvenience of manual operation and facilitates the assembly and use of the extra-large span vertical turning steel truss. The extra-large span vertical turning steel truss can be released by controlling the lifting mechanism to move downward. Then, the output end of the second telescopic mechanism 12 can be reset to facilitate the next clamping operation.

[0021] The lifting mechanism described above can be any type of lifting device. In order to stabilize the lifting and moving of the clamping frame 14, in this solution, the lifting mechanism includes a lead screw 16, a threaded hole, and an adjusting motor 17. The lead screw 16 is located in the lifting groove, and the adjusting motor 17 is installed inside the rectangular plate 13. The output end of the adjusting motor 17 is connected to the lead screw 16. The threaded hole is opened on the clamping frame 14, and the lead screw 16 passes through the threaded hole. The rectangular plate 13 is provided with a heat dissipation mechanism. By controlling the output end of the adjusting motor 17 to rotate the lead screw 16, and by the lead screw 16 passing through the threaded hole of the clamping frame 14, the clamping frame 14 can be stably lifted and slid in the lifting groove, thereby facilitating clamping operations. The heat dissipation mechanism can ensure the heat dissipation and ventilation efficiency of the adjusting motor 17.

[0022] To ensure efficient heat dissipation and ventilation for the regulating motor 17, the heat dissipation mechanism in this design includes heat dissipation holes 18. These holes 18 are located on one side of the rectangular plate 13, and multiple holes 18 are provided. By connecting the interior of the rectangular plate 13 through these multiple holes 18, better heat dissipation and ventilation for the regulating motor 17 can be achieved.

[0023] To further securely lock the position of the rectangular plate 13, in this design, a fastening groove is provided on one side of the rectangular groove 11, and an iron plate 19 is provided on the fastening groove. An electromagnet 20 is provided between the rectangular plate 13 and the fastening groove. When the rectangular plate 13 moves to the designated position, the electromagnet 20 is activated, and the electromagnet 20 attracts the iron plate 19 in the fastening groove, thereby firmly fixing the rectangular plate 13 in position.

[0024] To improve the control stability of this structure, in this design, both the first telescopic mechanism 2 and the second telescopic mechanism 12 are hydraulic rods. Since the first telescopic mechanism 2 and the second telescopic mechanism 12 are hydraulic rods, the hydraulic rods have the characteristics of high movement accuracy and good stability, thereby improving control stability and accuracy.

[0025] In order to improve the control accuracy when rotating the mounting plate 1, in this solution, both the drive motor 7 and the adjustment motor 17 are servo motors. By using servo motors for both the drive motor 7 and the adjustment motor 17, the rotation accuracy of the mounting plate 1 when rotating the hydraulic lifter 5 and the rotation accuracy of the lead screw 16 when raising and lowering the clamping frame 14 can be improved.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
