[0027] Please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 ,in, Figure 1 A first three-dimensional structural schematic diagram of the automatic wrapping and curing device for bridge cylindrical piers provided by this utility model; Figure 2 A second three-dimensional structural schematic diagram of the automatic wrapping and curing device for bridge cylindrical piers provided by this utility model; Figure 3 A partial structural diagram of the automatic wrapping and curing device for bridge cylindrical piers provided by this utility model; Figure 4 A second partial structural schematic diagram of the automatic wrapping and curing device for bridge cylindrical piers provided by this utility model; Figure 5 This is a partial structural diagram of the automatic wrapping and curing device for bridge cylindrical piers provided by this utility model. The automatic wrapping and curing device for bridge cylindrical piers includes: a base plate 1, on which a rotating mechanism, a lifting mechanism, a wrapping mechanism, and a fixing mechanism are provided;
[0028] The rotating mechanism includes a support column 2, a turntable 3, a gear ring 4, a first motor 5, and a circular gear 6. The support column 2 is rotatably mounted on the top of the base plate 1, the turntable 3 is fixedly mounted on the top of the support column 2, the gear ring 4 is fixedly sleeved on the support column 2, the first motor 5 is fixedly mounted on the top of the base plate 1, and the circular gear 6 is fixedly mounted on the output shaft of the first motor 5.

[0029] The lifting mechanism includes multiple fixed plates 7, four rotating shafts 8, four winding rollers 9, four steel wire ropes 10, four driven bevel gears 11, a second motor 12, and a driving bevel gear 13. The multiple fixed plates 7 are all fixedly installed on the top of the turntable 3. The rotating shafts 8 are rotatably installed on two corresponding fixed plates 7. The winding rollers 9 are fixedly sleeved on the rotating shafts 8. The steel wire ropes 10 are wound around the winding rollers 9.

The driving bevel gears 13 are fixedly installed on the output shaft of the second motor 12. The driving bevel gears 13 mesh with the four driven bevel gears 11.
[0030] like Figure 4 As shown, the film winding mechanism includes a lifting frame 14, four vertical plates 15, four electric telescopic rods 16, four rectangular plates 17, four limiting seats 18, four limiting balls 19, two fixing rods 20, a support plate 21, and a film roll mounting rod 22. The lifting frame 14 is fixedly installed at the bottom end of the four steel wire ropes 10. The four vertical plates 15 are all fixedly installed on the lifting frame 14. The electric telescopic rods 16 are fixedly installed on the vertical plates 15. The rectangular plates 17 are fixedly installed on the output shaft of the electric telescopic rods 16. The limiting seats 18 are fixedly installed on the rectangular plates 17. The limiting balls 19 are installed inside the limiting seats 18. The two fixing rods 20 are all fixedly installed on the lifting frame 14. The support plate 21 is fixedly installed at one end of the two fixing rods 20. The film roll mounting rod 22 is fixedly installed at the top of the support plate 21.
[0031] By setting up a membrane winding mechanism, the limiting ball 19 can be kept close to the bridge pier, preventing the lifting frame 14 from shaking and colliding with the bridge pier during membrane winding.
[0032] like Figure 5 As shown, the fixing mechanism includes a positioning plate 23, two rectangular slots 24, two clamping plates 25, two screws 26, and two handwheels 27. The positioning plate 23 is mounted on the vertical plate 15. The two rectangular slots 24 are both opened at the bottom of the positioning plate 23. The clamping plates 25 are slidably mounted in the rectangular slots 24. The screws 26 are rotatably mounted on the outer wall of the clamping plates 25. One end of the screws 26 extends to the outside of the positioning plate 23 and is threadedly connected to the positioning plate 23. The handwheels 27 are fixedly mounted on one end of the screws 26.
[0033] By setting a fixing mechanism, the top end of the film roll mounting rod 22 can be fixed to prevent the film roll mounting rod 22 from deforming under force when winding the film.
[0034] like Figure 3 As shown, the turntable 3 has four strip-shaped slots, and the steel wire rope 10 passes through the strip-shaped slots;
[0035] By setting a strip-shaped through groove, the wire rope 10 can easily pass through the turntable 3, so that it can drive the lifting frame 14 to rise or fall.
[0036] like Figure 5 As shown, the positioning plate 23 has a circular through hole, and the film roll mounting rod 22 passes through the circular through hole and is adapted to the circular through hole;
[0037] By setting a circular through hole, the film roll mounting rod 22 can easily pass through the positioning plate 23, which restricts the top of the film roll mounting rod 22 and improves the stability of the film roll mounting rod 22.
[0038] like Figure 5 As shown, a limiting groove is provided on the positioning plate 23, and a limiting slider is slidably installed in the limiting groove. The bottom of the limiting slider is fixedly connected to the clamping plate 25.
[0039] By setting limit grooves and limit sliders, the clamping plate 25 can be guided and restricted, so that the clamping plate 25 can move smoothly.
[0040] The working principle of the automatic wrapping and curing device for bridge cylindrical piers provided by this utility model is as follows:
[0041] First step: When using, put the plastic film roll on the film roll mounting rod 22, and clamp the positioning plate 23 on the lifting frame 14. Make the film roll mounting rod 22 pass through the circular through hole. Turn the screw 26 through the handwheel 27. The screw 26 drives the clamping plate 25 to move so that the clamping plate 25 is clamped on the lifting frame 14. Start the electric telescopic rod 16. The electric telescopic rod 16 drives the rectangular plate 17, the limiting seat 18 and the limiting ball 19 to move so that the limiting ball 19 presses against the bridge pier.
[0042] The second step: Start the first motor 5. The first motor 5 drives the circular gear 6 to rotate, the circular gear 6 drives the gear ring 4 to rotate, the gear ring 4 drives the support column 2 and the turntable 3 to rotate, thereby causing the lifting frame 14 to rotate. Start the second motor 12. The second motor 12 drives the driving bevel gear 13 to rotate, the driving bevel gear 13 drives the driven bevel gear 11 and the rotating shaft 8 to rotate, the rotating shaft 8 drives the winding roller 9 to rotate, releasing the wire rope 10 and causing the lifting frame 14 to move down. At this time, the lifting frame 14 moves down and rotates at the same time, wrapping the plastic film around the bridge pier. The number of wrapping turns of the plastic film can be controlled by controlling the descent speed and rotation speed of the lifting frame 14.
