Description

Technical Field

[0001] This utility model relates to the technical field of lifting tools, and in particular to a lifting tool for hot-dip galvanizing steel components of power transmission towers. Background Technology

[0002] Power transmission towers are tower-shaped structures used for power transmission. Their structural characteristics are that all tower types are space truss structures, and the members are mainly composed of single equilateral angle steel or combined angle steel. When constructing power transmission towers, lifting equipment for hot-dip galvanizing of power transmission tower steel components is required. However, the existing equipment has certain problems in use and still needs continuous improvement.

[0003] As disclosed in the utility model patent application CN221216831U, a lifting device for hot-dip galvanizing steel components of power transmission towers includes a first mounting frame. Multiple sets of strip-shaped holes are formed on the bottom wall of the first mounting frame. Drive components are installed on both sides of the bottom wall of the first mounting frame. Multiple sets of connecting belts are fitted onto the outer walls of both sets of drive components. Mounting blocks with through-strip-shaped holes are installed on the outer walls of the multiple sets of connecting belts. A second mounting frame is installed at the bottom of the multiple sets of mounting blocks. A traction component is fixed to the bottom wall of the inner cavity of the second mounting frame. A horizontal plate is fixed to the bottom of the traction component. Multiple sets of protruding columns are evenly fixed to the top wall of the horizontal plate. Power transmission tower steel components of different specifications are stacked on the multiple sets of protruding columns. Activating the traction component moves the power transmission tower steel components, thereby enabling the lifting and transport of power transmission tower steel components of different specifications.

[0004] When adjusting the height of the first mounting frame, the device needs to move the first mounting frame up and down to drive the support rod to move synchronously to the appropriate height in the inner cavity of the support tube. Then, the bolts are screwed to make them threadedly connected to the positioning holes, thereby fixing the height of the support rod and the first mounting frame. However, the first mounting frame is equipped with two sets of forward and reverse motors and other components, which makes it have a certain weight. This makes it somewhat inconvenient to adjust the height of the first mounting frame from the ground. Utility Model Content

[0020] Example

[0021] Please refer to Figure 1-4As shown, this utility model provides a lifting tool for hot-dip galvanizing steel components of power transmission towers. A support riser 2 is fixedly installed at the top of each of the two counterweight boxes 1. A support rod 3 is then installed inside each of the two support risers 2, with the rear wall of the support rod 3 slidingly connected to the inner wall of the support riser 2. A first mounting frame 11 is connected to the top walls of the two support rods 3. A rack 4 is installed on the surface of each of the two support rods 3, and a gear 5 is rotatably connected to each of the two support risers 2, located on the surface of the rack 4. The gear 5 allows for... It is connected to the rack 4, and then a rotating rod 6 is fixedly inserted at the center of the gear 5. Then, one end of the rotating rod 6 passes through the surface of the support tube 2 and is connected to the worm gear 7. A worm 8 is connected below the worm gear 7. At the same time, a rotating shaft 9 is fixedly inserted at the center of the worm 8. A limit seat 10 is fixedly installed on the surface of the support tube 2 and at both ends of the rotating shaft 9. One end of the rotating shaft 9 is connected to the limit seat 10 for limited rotation, and the other end passes through the surface of the limit seat 10 and is connected to the servo motor. The rotation of the rotating shaft 9 can be adjusted by the setting of the servo motor.

[0022] When adjusting the height of the first mounting frame 11 from the ground, the power supply of the two servo motors is first turned on. Then, the servo motors drive the two rotating shafts 9 and the worm gears 8 located on the outside of the rotating shafts 9 to rotate. Then, the two worm gears 8 are meshed with the worm wheel 7, so that the rotating rod 6 drives the gear 5 to rotate. Then, the rotating adjustment gear 5 is meshed with the rack 4, which drives the support rod 3 and the first mounting frame 11 located at the top of the two support rods 3 to adjust the height. This structure can automatically, quickly and conveniently realize the movement and adjustment of the height of the first mounting frame 11. Moreover, the meshing between the worm wheel 7 and the worm gear 8 has a certain self-locking property, so that the first mounting frame 11 can be fixed while adjusting the height.

[0023] As a further implementation of this embodiment, such as Figure 1-4As shown, a lead screw 13 is rotatably connected within the first mounting frame 11, and a slider 14 is threadedly connected to the outside of the lead screw 13. A second mounting frame 12 is connected below the slider 14. A pull rope 15 is positioned below the second mounting frame 12, and an electrically controlled winch for pulling and winding the pull rope 15 is installed inside the second mounting frame 12. A horizontal plate 16 is connected to the bottom end of the pull rope 15, and two placement frames 17 are symmetrically arranged on the bottom wall of the horizontal plate 16. Meanwhile, in the bottom wall of the second mounting frame 12... A pressure plate 18 is provided at the intermediate position, and a threaded rod 19 is rotatably connected to the upper surface of the pressure plate 18. The threaded rod 19 is threaded through the upper surface of the horizontal plate 16. By rotating the threaded rod 19, the pressure plate 18 can be pushed down, thereby limiting the steel tower components placed on the two placement frames 17. Then, a counterweight block 20 is provided in each of the two counterweight boxes 1. Finally, a brake caster 21 is provided at the four corners of the bottom wall of each of the two counterweight boxes 1. The entire device can be moved and adjusted by the brake caster 21.

[0024] In use, first place the steel tower components in the two placement frames 17, then rotate the threaded rod 19 to push the pressure plate 18 down, and then limit the steel tower components by the down-moving pressure plate 18. Then, drive the pull rope 15 to wind up by the electric winch set in the second mounting frame 12, and then lift the horizontal plate 16 and the steel tower components set below the horizontal plate 16 by the winding pull rope 15. At the same time, the screw rod 13 can be adjusted to drive the slider 14 to move the second mounting frame 12 and the steel tower components below the second mounting frame 12 in parallel to adjust to the appropriate position.

[0025] Specific working principle:

[0026] When using the device, first move the device to a suitable position, then place the counterweight 20 into the counterweight box 1. Then, adjust the height of the first mounting frame 11 from the ground. First, turn on the power to the two servo motors. Then, the servo motors drive the two rotating shafts 9 and the worm gears 8 located outside the rotating shafts 9 to rotate. The two worm gears 8 mesh with the worm wheel 7, causing the rotating rod 6 to drive the gear 5 to rotate. Then, the rotating adjustment gear 5 meshes with the rack 4, driving the support pole 3 and the first mounting frame 11 located at the top of the two support poles 3 to adjust their height. Then, place the steel tower components into the two placement frames 17. Next, rotate the threaded rod 19, which pushes the pressure... The plate 18 moves down, and the lowered pressure plate 18 limits the position of the steel tower component. Then, the electric winch in the second mounting frame 12 drives the pull rope 15 to wind up. The wound pull rope 15 then lifts the horizontal plate 16 and the steel tower component below the horizontal plate 16. At the same time, the screw 13 can be adjusted to drive the slider 14 to move the second mounting frame 12 and the steel tower component below the second mounting frame 12 in parallel to adjust to the appropriate position. Finally, the electric winch in the second mounting frame 12 drives the pull rope 15 and the horizontal plate 16 at the bottom of the pull rope 15 to move down, thereby placing the steel tower component below the horizontal plate 16 in the appropriate position.
