Description

Technical Field

[0001] This utility model relates to the field of steel tower assembly technology, specifically to an auxiliary positioning device for steel tower assembly. Background Technology

[0002] Steel towers are the supporting structures required for power transmission lines. Their main function is to erect power transmission lines high in the air, keeping them away from the ground and buildings, thus avoiding harm to the surrounding environment and people.

[0003] Currently, steel tower assembly involves using helicopters to directly hoist the assembled tower sections above the intended tower section and hover them. The helicopter pilot then controls the helicopter, guiding the hoisted tower section into the installation position with the help of the guiding device in the docking assistance system. This ensures accurate docking between the hoisted tower section and the already positioned tower section. While this operation is convenient and quick, the installation of the steel tower base inevitably causes the tower to sway due to external forces. Operators must support the base from all sides and coordinate with the pilot to move it multiple times to fully dock the base with the installation platform, significantly consuming manpower and greatly reducing assembly efficiency.

[0004] Therefore, it is particularly important to improve the existing auxiliary positioning devices for steel tower assembly, design a new type of auxiliary positioning device for steel tower assembly to solve the above-mentioned technical defects, and improve the practicality of the overall auxiliary positioning device for steel tower assembly. Utility Model Content

[0005] The purpose of this invention is to provide an auxiliary positioning device for steel tower assembly, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An auxiliary positioning device for steel tower assembly includes a platform with a groove on the top of the platform. A fixed platform is installed between the grooves. A support platform is installed inside the platform. A first pulley is installed at the right end of the top of the support platform, and a second pulley is installed at the left end of the top of the support platform. A belt is fitted between the first pulley and the second pulley. A first rotating wheel and a second rotating wheel are respectively installed on the top of the support platform and between the belts. A synchronous belt is fitted between the first rotating wheel and the second rotating wheel.

[0008] As a preferred embodiment of this utility model, a connecting rod is installed inside the first pulley, a drive motor is installed at the end of the connecting rod away from the first pulley, and a fixing frame is installed outside the connecting rod.

[0009] As a preferred embodiment of this utility model, a mounting bracket is installed on the outside of the second pulley, an extension side is installed at the bottom of the mounting bracket, and an installation groove is opened inside the extension side. The mounting bracket is connected to the support platform through the installation groove.

[0010] As a preferred embodiment of this utility model, the first rotating wheel is provided in four sets, and a linkage rod is installed between each of the four sets of the first rotating wheel.

[0011] As a preferred embodiment of this utility model, a first connecting box is installed at the bottom of both the belt and the timing belt, and the belt and the timing belt extend to the outside of the first connecting box. A first slider is symmetrically installed at the bottom of the first connecting box, and a first slide rail is installed on the outside of the first slider.

[0012] As a preferred embodiment of this utility model, a second connecting box is installed on the top of both the belt and the timing belt, a second slider is symmetrically installed on the bottom of the second connecting box, a second slide rail is installed on the outside of the second slider, and a U-shaped frame is installed on the bottom of the second slide rail.

[0013] As a preferred embodiment of this utility model, clamping rods are installed on the top of both the first connecting box and the second connecting box, and the clamping rods extend to the outside of the waist groove, and a threaded groove is opened inside the fixing platform.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] In this invention, by starting the drive motor, the output of the drive motor drives the connecting rod to rotate, thereby achieving uniform rotation of the first pulley. Simultaneously, the belt transmits the rotational force of the first pulley to the outside of the second pulley, causing the second pulley to rotate accordingly. By rotating the first rotating wheel, the rotational force is transmitted to the outside of the second rotating wheel via the synchronous belt, causing the second and first rotating wheels to move in tandem. This allows the first and second connecting boxes to approach each other outside the belt and synchronous belt. At the same time, the first and second sliders slide inside the first and second slide rails respectively, and the first and second sliders limit the movement of the first and second connecting boxes, allowing them to move linearly along a straight line. This allows the clamping rod to slide inside the groove, causing it to move towards the fixed platform, thereby limiting the movement of the steel tower base. This ensures that the mounting holes of the steel tower base precisely align with the threaded groove, and the installation is completed by reinforcing bolts and threaded grooves, achieving the fixed installation of the steel tower base.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Example:

[0023] Please see Figures 1-4 This utility model provides a technical solution:

[0024] An auxiliary positioning device for steel tower assembly includes a platform 1, a groove 2 on the top of the platform 1, a fixed platform 3 installed between the grooves 2, a support platform 4 installed inside the platform 1, a first pulley 5 installed at the right end of the top of the support platform 4, a second pulley 6 installed at the left end of the top of the support platform 4, a belt 7 sleeved between the first pulley 5 and the second pulley 6, a first rotating wheel 8 and a second rotating wheel 9 respectively installed on the top of the support platform 4 and between the belts 7, and a synchronous belt 10 sleeved between the first rotating wheel 8 and the second rotating wheel 9.

[0025] For further details, please refer to Figure 3In this embodiment, a connecting rod 11 is installed inside the first pulley 5. A drive motor is installed at the end of the connecting rod 11 away from the first pulley 5, and a fixing frame 12 is installed on the outside of the connecting rod 11. When assembling the steel tower, the base of the steel tower is first lowered vertically above the platform 1 by a crane or helicopter. However, external influences will inevitably cause the base of the steel tower to shake. Workers support the four sides of the base, and by starting the drive motor, the output end of the drive motor will drive the connecting rod 11 to rotate, thereby making the first pulley 5 rotate at a constant speed. At the same time, the belt 7 will transmit the rotational force of the first pulley 5 to the outside of the second pulley 6, so that the second pulley 6 will follow the rotation. By rotating the first rotating wheel 8, the rotational force is transmitted to the outside of the second rotating wheel 9 through the synchronous belt 10, so that the second rotating wheel 9 and the first rotating wheel 8 follow the movement. Through the cross design of the synchronous belt 10 and the belt 7, there is no obstruction between the synchronous belt 10 and the belt 7 when they run.

[0026] Please refer to Figure 3 In this embodiment, a retainer 13 is installed on the outside of the second pulley 6. An extension side is installed at the bottom of the retainer 13, and an installation groove is opened inside the extension side. The retainer 13 is connected to the support platform 4 through the installation groove. Through the design of the retainer 13, the second pulley 6 can run smoothly when rotating, thus enhancing its practicality.

[0027] Furthermore, please refer to Figure 3 In this embodiment, the first rotating wheel 8 is provided in four sets, and a linkage rod 14 is installed between the four sets of first rotating wheels 8. Through the design of the linkage rod 14, when the first rotating wheel 8 rotates, it will cause the other set of first rotating wheels 8 to rotate synchronously, thereby greatly improving their linkage.

[0028] For further details, please refer to Figure 3 and Figure 4In this embodiment, a first connecting box 15 is installed at the bottom of both the belt 7 and the timing belt 10, and the belt 7 and the timing belt 10 extend to the outside of the first connecting box 15. A first slider 16 is symmetrically installed at the bottom of the first connecting box 15, and a first slide rail 17 is installed on the outside of the first slider 16. A second connecting box 18 is installed at the top of both the belt 7 and the timing belt 10, and a second slider 19 is symmetrically installed at the bottom of the second connecting box 18. A second slide rail 20 is installed on the outside of the second slider 19, and a U-shaped frame 21 is installed at the bottom of the second slide rail 20. By rotating the belt 7 and the timing belt 10 in a cycle, the first connecting box 15 and the second connecting box 18 are brought closer to each other outside the belt 7 and the timing belt 10. At the same time, the first slider 16 and the second slider 19 slide inside the first slide rail 17 and the second slide rail 20, respectively. The first slider 16 and the second slider 19 limit the first connecting box 15 and the second connecting box 18, respectively, so that they can only move linearly along a straight line.

[0029] For further details, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 In this embodiment, clamping rods 22 are installed on the top of both the first connecting box 15 and the second connecting box 18, and the clamping rods 22 extend to the outside of the waist groove 2. The fixed platform 3 has a threaded groove 23 inside. When the first connecting box 15 and the second connecting box 18 approach each other, the clamping rods 22 slide inside the waist groove 2, so that the clamping rods 22 move towards the fixed platform 3, thereby limiting the steel tower base and making the mounting hole of the steel tower base accurately align with the threaded groove 23. Thus, the installation is completed by reinforcing bolts and threaded groove 23, and the fixed installation of the steel tower base is achieved.

[0030] In this embodiment, the specific implementation scenario is as follows: During the assembly and construction of the steel tower, the base of the steel tower is first vertically lowered from above platform 1 using a crane or helicopter. However, external influences will inevitably cause the base of the steel tower to sway. Workers support the four sides of the base, and by starting the drive motor, the output of the drive motor drives the connecting rod 11 to rotate, thereby achieving uniform rotation of the first pulley 5. At the same time, the belt 7 transmits the rotational force of the first pulley 5 to the outside of the second pulley 6, thus achieving rotation of the second pulley 6. By rotating the first rotating wheel 8, the rotational force is transmitted to the outside of the second rotating wheel 9 through the synchronous belt 10, thereby achieving uniform rotation of the second rotating wheel 9 and the first rotating wheel 8. The rotating wheel 8 moves accordingly, thereby bringing the first connecting box 15 and the second connecting box 18 closer together outside the belt 7 and the synchronous belt 10. At the same time, the first slider 16 and the second slider 19 slide inside the first slide rail 17 and the second slide rail 20, respectively. The first slider 16 and the second slider 19 limit the first connecting box 15 and the second connecting box 18, so that they can only move linearly along a straight line. This allows the clamping rod 22 to slide inside the waist groove 2, causing the clamping rod 22 to move towards the fixed platform 3, thereby limiting the steel tower base. This ensures that the mounting hole of the steel tower base is precisely aligned with the threaded groove 23, and the installation is completed by reinforcing bolts and threaded groove 23, thus achieving the fixed installation of the steel tower base.

[0031] 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.
