Description

Technical Field

[0001] The utility model belongs to the technical field of galvanizing equipment, and particularly relates to a lifting device for galvanizing lamp poles. Background Technique

[0002] Hot-dip galvanizing is to make the molten metal react with the iron matrix to produce an alloy layer, so that the matrix and the coating are combined. First, the steel parts are pickled to remove the iron oxide on the surface of the steel parts. After pickling, they are cleaned in an ammonium chloride or zinc chloride aqueous solution or a mixed aqueous solution of ammonium chloride and zinc chloride, and then sent into the hot-dip galvanizing tank. Hot-dip galvanizing has the advantages of uniform coating, strong adhesion, and long service life. Among the objects that need to be galvanized, there is a kind of lamp pole, which needs to be lifted into the galvanizing tank by a lifting device for galvanizing.

[0003] In the existing lifting device for galvanizing lamp poles, after the galvanizing of the lamp pole is completed, the lamp pole can only be lifted out of the galvanizing tank, and the position of the lamp pole cannot be adjusted. After the galvanized lamp pole is lifted above the galvanizing tank, due to the limitation of the galvanizing tank, it is not convenient to remove the lamp pole from the lifting device.

[0004] Refer to the Chinese authorized patent with the authorization announcement number: CN220449547U: A lifting fixture for hot-dip galvanizing treatment. In this utility model, by starting the second motor, the output end of the second motor rotates forward to drive the bidirectional lead screw to rotate forward, so that the two moving plates slide inwards towards each other on the sliding rod, and at the same time, the clamping seat follows and slides inwards towards each other to clamp the lamp pole. Then, the second motor is started again, so that the second motor rotates in the reverse direction, and at the same time drives the bidirectional lead screw to rotate in the reverse direction, so that the two moving plates move outwards towards each other, indirectly causing the clamping seat to release the lamp pole. It is convenient to clamp and disassemble the lamp pole, avoiding manual installation and disassembly with tools, which is beneficial to improving the galvanizing efficiency.

[0005] However, it also has the above technical problems in the use process. The lamp pole can only be lifted out of the galvanizing tank, and the position of the lamp pole cannot be adjusted. After the galvanized lamp pole is lifted above the galvanizing tank, due to the limitation of the galvanizing tank, it is not convenient to remove the lamp pole from the lifting device. Summary of the Utility Model

[0006] The purpose of the utility model is to provide a lifting device for galvanizing lamp poles to solve the problem that the lamp pole can only be lifted out of the galvanizing tank and the position of the lamp pole cannot be adjusted as mentioned in the above background technique.

[0007] To achieve the above object, the present utility model provides the following technical solution: A hoisting device for galvanizing a lamp post, including a fixed box and two guiding boxes fixed to one side of the fixed box. The bottom wall of the inner cavity of the fixed box is provided with a dual-axis motor I. Both output ends of the dual-axis motor I are fixed with driving shafts. The outer wall of the driving shaft is fixed with a driving bevel gear. A guiding screw is rotatably connected in the guiding box, and the end face of the guiding screw is fixed with a driven bevel gear meshing with the driving bevel gear. The outer wall of the guiding screw is threadedly connected with a supporting rod;

[0008] A positioning box is movably connected between the two supporting rods. Two limiting blocks for fixing the position of the lamp post are movably connected in the positioning box. Through holes are opened on the opposite surfaces of the two limiting blocks, and a positioning column is movably connected in the through holes of the limiting blocks.

[0009] In a further embodiment, positioning blocks are fixed to the tops of the two supporting rods. A rotary motor is installed on the outer wall of one side of the positioning block, and a rotating column is fixed to the output end of the rotary motor.

[0010] In a further embodiment, two winding discs are fixed to the outer wall of the rotating column. Steel wires are wound around the outer walls of the winding discs, and a pull ring fixedly connected with the positioning box is fixed to the end face of the steel wire.

[0011] In a further embodiment, a dual-axis motor II is installed on the bottom wall of the inner cavity of the positioning box. Both output ends of the dual-axis motor II are fixed with moving screws, and the limiting blocks are threadedly connected with the moving screws.

[0012] In a further embodiment, through holes are opened on the outer wall of one side of the limiting block, and a positioning pin is movably connected in the through holes of the limiting block. A positioning hole matching the positioning pin is opened on the outer wall of one side of the positioning column.

[0013] In a further embodiment, a limiting ring is fixed to the outer wall of the positioning pin, and a fixing spring for supporting the limiting ring is sleeved outside the positioning pin.

[0014] The technical effects and advantages of the present utility model:

[0015] For the hoisting device for galvanizing a lamp post, the dual-axis motor I drives the driving shafts and the driving bevel gears to rotate. The driving bevel gear drives the guiding screw to rotate through the driven bevel gear, thereby driving the supporting rod to move, enabling the lamp post fixed between the two limiting blocks to move to a suitable position, avoiding the galvanizing tank restricting the disassembly and assembly of the lamp post;

[0016] By the rotation of the dual-axis motor II, the moving screws can be driven to rotate, thereby adjusting the distance between the two limiting blocks according to the length of the lamp post, fixing lamp posts of different sizes, and improving the application range of the device;

[0017] Two positioning columns are inserted into the two ends of the lamp pole, and the limit block does not contact the lamp pole, thereby reducing the contact area with the lamp pole, making the galvanizing of the lamp pole more comprehensive, and the detachable positioning columns are convenient for later maintenance and replacement. The galvanizing lifting device of the lamp pole can move the lamp pole to a suitable position after the galvanizing of the lamp pole is completed, which is convenient for taking and placing the lamp pole.

DETAILED DESCRIPTION

[0025] In the following description, a large number of specific details are given to provide a more thorough understanding of the utility model. However, it is obvious to those skilled in the art that the utility model can be implemented without one or more of these details. In other examples, in order to avoid confusion with the utility model, some technical features known in the art are not described.

[0026] Unless otherwise indicated by a separately defined direction, the directions such as up, down, left, right, front, back, inside and outside involved in this article are based on the up, down, left, right, front, back, inside and outside directions in the figures shown by the present utility model, which is hereby explained together.

[0027] Please refer to Figures 1-5 , the present utility model provides a hoisting device for galvanizing a lamp post, which includes a fixed box 1 and two guiding boxes 5 fixed on one side of the fixed box 1. The bottom wall of the inner cavity of the fixed box 1 is bolted with a double-shaft motor 1 2. Both output ends of the double-shaft motor 1 2 are fixed with drive shafts 3 through couplings. The outer wall of the drive shaft 3 is welded with a driving bevel gear 4. A guiding screw rod 6 is rotatably connected through the welded axis in the guiding box 5. The end face of the guiding screw rod 6 is welded with a driven bevel gear 7 meshing with the driving bevel gear 4. The outer wall of the guiding screw rod 6 is threadedly connected with a supporting rod 8. The surface of the guiding box 5 is provided with a guiding groove for the supporting rod 8 to move. The thread groove directions of the two driving bevel gears 4, the driven bevel gear 7 and the guiding screw rod 6 can be set according to actual use requirements. When the double-shaft motor 1 2 works to drive the two guiding screw rods 6 to rotate, it is ensured that the two supporting rods 8 move synchronously;

[0028] A positioning box 13 is movably connected between the two supporting rods 8. The tops of the two supporting rods 8 are both welded with positioning blocks 9. A rotary motor 10 is bolted on the outer wall of one side of the positioning block 9. The output end of the rotary motor 10 is fixed with a rotating column 11 through a coupling. The rotating column 11 is rotatably connected with the other positioning block 9 through a welded bearing. Two winding discs 12 are fixed on the outer wall of the rotating column 11. Steel wires are wound around the outer walls of the winding discs 12. The end face of the steel wire is fixed with a pull ring fixedly connected with the positioning box 13. Rotating grooves are opened on both outer walls of the positioning box 13. Limiting balls 14 are rotatably connected in the rotating grooves of the positioning box 13. Limiting sliding grooves for the limiting balls 14 to slide are opened on the opposite faces of the two supporting rods 8. The limiting balls 14 can limit the moving path of the positioning box 13 and at the same time ensure that the positioning box 13 moves more smoothly between the two supporting rods 8;

[0029] The bottom wall of the inner cavity of the positioning box 13 is installed with a double-shaft motor II 15 through bolts. Both output ends of the double-shaft motor II 15 are fixed with moving screws 16 through couplings. The thread grooves of the two moving screws 16 have opposite directions. The outer wall of the moving screw 16 is threadedly connected with a limiting block 17 for fixing the position of the lamp post. Two moving grooves for the limiting block 17 to move are opened at the bottom of the positioning box 13. Through holes are opened on the opposite surfaces of the two limiting blocks 17, and a positioning column 18 is movably connected in the through hole of the limiting block 17. By rotating the double-shaft motor II 15, the moving screw 16 can be driven to rotate, so as to adjust the distance between the two limiting blocks 17 according to the length of the lamp post and fix lamp posts of different sizes, improving the scope of use of the device. The two positioning columns 18 are inserted into the two ends of the lamp post, and the limiting block 17 does not contact the lamp post, thus reducing the contact area with the lamp post and making the galvanizing of the lamp post more comprehensive. By driving the driving shaft 3 and the driving bevel gear 4 to rotate through the double-shaft motor I 2, the driven bevel gear 7 drives the guiding screw 6 to rotate, thereby driving the support rod 8 to move, enabling the lamp post fixed between the two limiting blocks 17 to move to a suitable position and avoiding the galvanizing tank restricting the disassembly and assembly of the lamp post;

[0030] A through hole is opened on the outer wall of one side of the limiting block 17, and a positioning pin 19 is movably connected in the through hole of the limiting block 17. A positioning hole matching the positioning pin 19 is opened on the outer wall of one side of the positioning column 18. A limiting ring 20 is fixed on the outer wall of the positioning pin 19, and a fixing spring 21 for supporting the limiting ring 20 is sleeved outside the positioning pin 19. The fixing spring 21 supports the limiting ring 20, enabling the positioning pin 19 to be inserted into the positioning hole of the positioning column 18, thereby fixing the position of the positioning column 18. Pull the positioning pin 19 to separate the positioning pin 19 from the positioning column 18, and pull the positioning pin 19 outwards to disassemble the positioning pin 19, which is convenient for its maintenance and replacement.

[0033] Working principle:

[0034] When the hoisting device for galvanizing the lamp post is in use, two guiding boxes 5 are installed on both sides of the galvanizing tank, and then the lamp post to be galvanized is placed between two limiting blocks 17. The double-shaft motor II 15 is started to drive the moving screw 16 to rotate. According to the length of the lamp post, the distance between the two limiting blocks 17 is adjusted so that the two positioning columns 18 are inserted into both ends of the lamp post to fix the position of the lamp post. The rotating motor 10 is started to drive the rotating column 11 and the winding disc 12 to rotate, so that the lamp post descends into the galvanizing tank for galvanizing operation on the lamp post.

[0035] After the galvanizing of the lamp post is completed, the rotating motor 10 rotates in the reverse direction to move the lamp post above the galvanizing tank. The double-shaft motor I 2 is started to drive the driving shaft 3 and the driving bevel gear 4 to rotate. The driving bevel gear 4 drives the guiding screw 6 to rotate through the driven bevel gear 7, thereby driving the support rod 8 to move, so that the lamp post fixed between the two limiting blocks 17 is moved to a suitable position to avoid the galvanizing tank restricting the disassembly and assembly of the lamp post. After the lamp post is moved to a suitable position, the double-shaft motor II 15 rotates in the reverse direction to separate the positioning column 18 from the lamp post, and the galvanized lamp post is removed from the hoisting device.
