However, the construction of sluice gate piers is mostly in low-lying river valleys, making it difficult for truck cranes to enter and exit. Furthermore, when hoisting the formwork of multiple piers, the hoisting height is limited by the specifications of the cylinder itself. There is room for improvement in both height adjustment and overall hoisting efficiency, and it does not have the function of facilitating large-span hoisting.

A locking block is fixedly connected to the output end of the electric cylinder. Limiting slide rails are vertically welded to both sides of the front and rear ends inside the main fixing frame. Multiple sets of locking slots are opened inside the limiting slide rails.

[0010] As a further technical solution of this utility model, the steel cable of the third winch is connected to the lifting ring, and the shape and size of the outside of the I-shaped frame are matched with the shape and size of the inside of the main fixed frame, so that the I-shaped frame can slide up and down along the inside of the main fixed frame.

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.

[0030] Example: Please refer to Figure 1-5 A high formwork hoisting device for a sluice gate includes two sets of support frames 1. A main fixing frame 2 is fixedly connected to the top of the support frame 1. A PLC controller 3 is fixedly connected to the front end of the top of the support frame 1. A central frame 4 is set inside the main fixing frame 2. Two sets of balance cables 7 and one set of travel cables 8 are arranged horizontally between the two sets of central frames 4. A traction frame 21 is fixedly connected to the side of the support frame 1. An adjustment component that can further adjust the height is set at the top of the main fixing frame 2.

[0031] Please see Figure 1-5 A high-formwork hoisting device for a sluice gate also includes an adjustment assembly. The adjustment assembly includes two sets of third winches 9, which are respectively installed at the front and rear ends of the top of the main fixed frame 2. Lifting rings 10 are welded to the front and rear ends of the top of the central frame 4. I-beams 11 are fixedly connected to the front and rear ends of the central frame 4. Pre-grooved slots 12 are provided on both sides of the top of the I-beams 11. Electric cylinders 13 are fixedly connected inside the pre-grooved slots 12. A locking block 1 is fixedly connected to the output end of the electric cylinders 13. 4. Limiting slide rails 15 are vertically welded to both sides of the front and rear ends inside the main fixed frame 2. Multiple sets of slots 16 are opened inside the limiting slide rails 15. A lifting trolley 22 is set outside the balance cable 7 and the traveling cable 8. Balance pulleys 23 are set at both the front and rear ends inside the lifting trolley 22. A drive pulley 24 is set at the bottom inside the lifting trolley 22. A fourth winch 25 is installed on both sides of the top of the lifting trolley 22. The steel cables of the two sets of fourth winches 25 are synchronously suspended by lifting devices 26.

[0032] The steel cable of the third winch 9 is connected to the lifting ring 10. The external shape and size of the I-shaped frame 11 are adapted to the internal shape and size of the main fixed frame 2. The I-shaped frame 11 can slide up and down along the inside of the main fixed frame 2. The locking block 14 passes through the I-shaped frame 11 and extends to the outside. The shape and size of the locking block 14 are adapted to the shape and size of the locking slot 16. The locking slot 16 is arranged at equal intervals. The PLC controller 3, the third winch 9, and the electric cylinder 13 are electrically connected, which facilitates hoisting in a large-span river channel.

[0033] Specifically, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the sluice gate template is suspended on the lifting device 26. The fourth winch 25 winds up and lifts it. Driven by the motor, the driving pulley 24 drives the trolley 22 to travel along the balance cable 7 and the traveling cable 8 above the river. During the hoisting process, in addition to adjusting the tension, the height of the balance cable 7 and the traveling cable 8 can also be further adjusted. The third winch 9 pulls the central frame 4 upward through the lifting ring 10. The central frame 4 slides up and down along the inside of the main fixed frame 2. During the adjustment, the electric cylinder 13 retracts. After adjusting to the appropriate position, the electric cylinder 13 extends, and the locking block 14 is locked into the slot 16 of the limiting slide rail 15 to limit its position. With the fourth winch 25, the up and down adjustment can be more precise and flexible, avoiding the cable bending down in the middle position and causing the position to be too low. It is convenient for construction on a large-span river.

[0034] Two sets of first winches 5 are installed on one side inside the central frame 4, and a second winch 6 is installed at the bottom inside the central frame 4.

The PLC controller 3, the first winch 5, and the second winch 6 are electrically connected to facilitate the adjustment of the cable tension.

[0035] Specifically, such as Figure 1 and Figure 3 As shown, the balance cable 7 and the travel cable 8 serve as the main supporting steel cables. Their tension is controlled by the first winch 5 and the second winch 6. The first winch 5 and the second winch 6 can control their tension by winding and releasing, thus facilitating the adjustment of their height.

[0036] Limiting cylinders 17 are fixedly connected to the front and rear ends of one side of the top of the load-bearing frame 1. A positioning pile 18 is vertically inserted into the inside of the limiting cylinder 17. A hammer head 19 is welded to the top of the positioning pile 18. A lifting hole 20 is provided inside the hammer head 19. The outer diameter of the positioning pile 18 is matched with the inner diameter of the limiting cylinder 17. The positioning pile 18 can slide up and down along the inside of the limiting cylinder 17 for easy and quick fixation.

[0037] Specifically, such as Figure 1 and Figure 2As shown, with the two sets of supporting frames 1 in place, the positioning piles 18 are inserted along the limiting cylinder 17, and the hammer head 19 is hammered by the pile driving equipment. The positioning piles 18 are driven into the ground, making the positions of the supporting frames 1 on both sides stable, and the lifting holes 20 facilitate lifting and subsequent pile removal.

[0038] Working Principle: In use, the first step is towing the support frame 1 by a semi-trailer. Two sets of support frames 1 are positioned on either side of the river channel. As the two sets of support frames 1 are in place, positioning piles 18 are inserted along the limiting cylinder 17. The pile driving equipment then hammers the hammer head 19, driving the positioning piles 18 into the ground, stabilizing the positions of the support frames 1 on both sides. The lifting hole 20 facilitates lifting and subsequent pile removal. The balance cable 7 and travel cable 8 are taut and pulled. The sluice gate template is suspended on the lifting device 26, and the fourth winch 25 rewinds and lifts it. Driven by the motor, the drive pulley 24 pulls the lifting trolley 22 along the balance cable... 7. The traveling cable 8 travels above the river channel. During hoisting, in addition to adjusting the tension, the height of the balance cable 7 and the traveling cable 8 can be further adjusted. The third winch 9 pulls the central frame 4 upward through the lifting ring 10. The central frame 4 then slides up and down along the inside of the main fixed frame 2. During adjustment, the electric cylinder 13 retracts. After adjusting to the appropriate position, the electric cylinder 13 extends, and the locking block 14 engages with the slot 16 of the limiting slide rail 15 to limit its position. With the cooperation of the fourth winch 25, the up and down adjustment can be more precise and flexible, avoiding the cable bending downward in the middle position and causing the position to be too low. This facilitates construction on large-span river channels. The balance cable 7 and the traveling cable 8, as the main supporting steel cables, have their tension controlled by the first winch 5 and the second winch 6. The first winch 5 and the second winch 6 can control their tension by winding and releasing, thus facilitating the adjustment of their height.
