[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Reference Figure 1 to Figure 2 An embodiment of the present invention is as follows: a hydraulic lifting system for a roof steel structure comprises two concrete pillars 1, wherein the concrete pillars 1 are the basic supports for the hydraulic lifting system for the entire roof steel structure, the top of the concrete pillars 1 is detachably connected with a bracket 2, the bracket 2 is the supporting structure of the entire lifting system, the top of the bracket 2 is fixedly connected with a support plate 3, the interior of the support plate 3 is fixedly connected with a hydraulic lifter 24, the hydraulic lifter 24 is the core power component of the hydraulic lifting system for the entire roof steel structure, the support plate 3 is fixed on the top of the bracket 2, and mainly plays the role of dispersing pressure and providing an installation platform for the hydraulic lifter 24.

[0032] A method for hydraulically lifting a roof steel structure, according to the above-mentioned hydraulic lifting system for a roof steel structure, the specific method comprises the following steps;

[0033] S1. First, place the bracket 2 on the top of the concrete pillar 1, fix it on the mounting seat 21 with the nut 30, and move the adjustment plate 19. As the screw rod 8 moves continuously, the tension between the adjustment column 6 and the screw rod 8 is adjusted;

[0034] S2, then loosen the adjustment plate 19, the spring 2 17 is no longer compressed to generate elastic force on the movable column 18, pushing it outward, so that the clamping plate 20 is engaged with the corresponding clamping groove ring 13;

[0035] S3. Connect the lock at the bottom of the steel strand 25 to the truss 26, then start the hydraulic lifter 24, lift the truss 26 to a certain height, and start the hydraulic lifter 24 again. During the lifting process, the balance detector 28 can detect the balance of the truss 26.

[0036] Reference Figure 3 to Figure 4 The outside of the bracket 2 is fixedly connected with a connecting frame 4, and the outside of the connecting frame 4 is fixedly connected with a fixing column 5. The connecting frame 4 is used to connect the fixing column 5 with the bracket 2, so as to provide a stable support and force transmission effect. The outside of the fixing column 5 is slidably connected with an adjusting column 6, and the fixing column 5 is fixed to the outside of the connecting frame 4, providing a guiding effect for the sliding of the adjusting column 6. The outside of the adjusting column 6 is sleeved with a spring 7, and one end of the spring 7 is fixedly connected to the outside of the fixing column 5. When the screw 8 pushes the adjusting column 6 to move, the spring 7 is squeezed to store elastic potential energy. The main function is to use its own elastic characteristics to generate a reaction force on the adjusting column 6 after the screw 8 pushes the abutment plate 9 to contact the concrete pillar 1, thereby adjusting the tension between the adjusting column 6 and the screw 8, so that the system maintains a stable stress state during operation and avoids structural damage due to uneven stress.

[0037] The other end of the spring 7 is fixedly connected to the inside of the adjusting column 6. A screw 8 is fixedly connected to the side of the adjusting column 6 away from the connecting frame 4. Driven by the screw 8, the adjusting column 6 can achieve position adjustment along the fixed column 5, thereby changing the working state of the entire system. A butt plate 9 is fixedly connected to the other side of the screw 8. The butt plate 9 is mainly used to contact the outside of the concrete pillar 1 to transmit the thrust of the screw 8. The butt plate 9 can stably resist the concrete pillar 1 and effectively transmit the thrust of the screw 8 to the concrete pillar 1. A collar 10 is fixedly connected to the inside of the bracket 2. A rotating ring 11 is rotatably connected to the inside of the collar 10. The collar 10 is fixed to the inside of the bracket 2 and has a smooth inner hole. The matching accuracy with the outer surface of the rotating ring 11 is high, which can make the rotating ring 11 rotate smoothly inside it, while ensuring the stability during the rotation process, providing rotation support for the rotating ring 11.

[0038] Reference Figures 5 to 7 A rotating handle 12 is fixedly connected to one side of the rotating ring 11. Driven by the rotating handle 12, the rotating ring 11 can rotate in the sleeve ring 10, thereby driving the slot ring 13 and the screw 8 connected thereto to rotate, so as to adjust the working position of the system. The screw 8 ensures that it can move smoothly and accurately during the rotation process. The screw 8 can move inside the bracket 2 by cooperating with the rotating ring 11 and driven by the rotating handle 12. As the screw 8 moves, it can drive the adjustment column 6 to slide outside the fixed column 5, so as to adjust the working position of the system.

[0039] A limit assembly is arranged inside the adjusting column 6, and the limit assembly includes a groove ring 13, the inside of the groove ring 13 is fixedly connected to the outside of the rotating ring 11, and the outside of the fixed column 5 is fixedly connected to two bosses 14, and the front and rear sides of the adjusting column 6 are provided with limit slots 15, and the external shape of the boss 14 matches the limit slots 15 provided on the adjusting column 6, and can slide in the limit slots 15, and the outside of the boss 14 is slidably connected to the inner wall of the limit slot 15, and the main function of the boss 14 is to limit the movement trajectory of the adjusting column 6 during the sliding process by cooperating with the limit slot 15, to ensure that the adjusting column 6 can only slide in a straight line along the direction of the fixed column 5, to avoid shaking or offset, etc., and to play a precise limiting role in the movement of the adjusting column 6.

[0040] A sliding groove 16 is provided on one side of the bracket 2 close to the collar 10, and a spring 2 17 is fixedly connected to one side of the inner wall of the sliding groove 16. The inner wall of the sliding groove 16 is smooth to ensure that the movable column 18 can slide smoothly inside it and provide stable support for the spring 2 17. The other end of the spring 2 17 is fixedly connected to the movable column 18. When the adjusting plate 19 is turned, the movable column 18 is forced to squeeze the spring 2 17, and the spring 2 17 is compressed to store elastic potential energy. The outside of the movable column 18 is slidably connected to the inner wall of the sliding groove 16, and the other side of the movable column 18 is fixedly connected to the adjusting plate 19. The surface of the adjusting plate 19 is provided with anti-slip textures to facilitate the operator to hold and apply force.

[0041] The outside of the adjustment plate 19 is fixedly connected with a card plate 20, and the shape and size of the card plate 20 match the card slot of the card slot ring 13. When the adjustment plate 19 is loosened, the spring 17 uses its own elastic properties to generate elastic force on the movable column 18, and pushes the movable column 18 outward, so that the card plate 20 is engaged with the card slot ring 13, so as to limit the rotation of the rotating handle 12. The outside of the card plate 20 is engaged with the inner wall of the card slot ring 13. The inner wall of the card slot ring 13 is designed with a plurality of card slots, which cooperate with the card plate 20 to limit the rotation of the rotating ring 11. When the card plate 20 is engaged with the card slot of the card slot ring 13, the rotating ring 11 cannot rotate, thereby limiting the movement of components such as the screw 8, and ensuring the stability of the system during operation.

[0042] Reference Figure 1 and Figure 8The outside of the bracket 2 is provided with an adjustment component, and the adjustment component includes a plurality of mounting seats 21. The outside of the mounting seat 21 is fixedly connected to the outside of the bracket 2, and the mounting seat 21 is firmly connected to the bracket 2 by bolt connection. The inside of the mounting seat 21 is detachably connected with a support frame 22, and a plurality of adjustment holes 23 are provided inside the support frame 22. The internal thread of the mounting seat 21 is connected with a nut 30. By selecting the adjustment holes 23 at different positions and fixing it to the mounting seat 21 with the nut 30, the position of the support frame 22 can be adjusted, thereby meeting the needs of the system in different working scenarios. The external thread of the nut 30 is connected with a locking bolt 29. By selecting the adjustment holes 23 at different positions and fixing it to the mounting seat 21 with the nut 30, the position of the support frame 22 can be adjusted, thereby meeting the needs of the system in different working scenarios.

[0043] A steel strand 25 is fixedly connected to the driving end of the hydraulic lifter 24, and a lock is fixedly connected to the other end of the steel strand 25. A truss 26 is detachably connected inside the two locks. One end of the steel strand 25 is fixedly connected to the driving end of the hydraulic lifter 24, and the other end is connected to the lock for connecting the truss 26. The truss 26 is connected to the steel strand 25 through the lock, and lifting is achieved under the action of the hydraulic lifter 24. Balance rods 27 are detachably connected to the left and right sides of the bottom of the truss 26. The balance rod 27 is mainly used to maintain the balance of the truss 26 during the lifting process. When the truss 26 is lifted to a certain height, the two ends of the balance rod 27 are fixed together with the lock, which can effectively prevent the truss 26 from shaking or deflecting during the lifting process, thereby ensuring the safety and stability of the lifting process. A balance detector 28 is fixedly connected to the bottom of the balance rod 27. The balance detector 28 is used to detect the balance state of the truss 26 during the lifting process in real time.

[0044] Working principle: first, place the bracket 2 on the top of the concrete pillar 1, then install the mounting seat 21 on the outside of the bracket 2, then select the adjustment hole 23 at the appropriate position and use the nut 30 to fix it on the mounting seat 21, then turn the adjustment plate 19, and at the same time, the movable column 18 is forced to squeeze the spring 17, and the spring 17 is compressed, so that the clamping plate 20 is separated from the clamping groove ring 13. At this time, turning the rotating handle 12 can drive the screw 8 to move inside the bracket 2. As the screw 8 continues to move, it can drive the adjustment column 6 to slide outside the fixed column 5. At this time, the spring 7 is compressed. When the screw 8 pushes the plate 9 to move to the concrete pillar 1 8, and the cam 14 also slides on the inner wall of the limiting groove 15 at the same time. When the abutment plate 9 abuts against the concrete pillar 1, the rotation of the rotating handle 12 stops, and the elastic properties of the spring 1 7 can produce a reaction force on the adjusting column 6, thereby adjusting the tension between the adjusting column 6 and the screw 8. After that, the adjusting plate 19 is released, and the spring 2 17 is no longer compressed to produce elastic force on the movable column 18, pushing it outward, so that the clamping plate 20 is engaged with the corresponding clamping groove ring 13, and the rotating handle 12 can be limited, thereby fixing the bracket 2 to the outside of the concrete pillar 1.

[0045] Then connect the lock at the bottom of the steel strand 25 to the truss 26, and then start the hydraulic lifter 24. When the truss 26 is lifted to a certain height, fix the two ends of the balance rod 27 with the lock, and then start the hydraulic lifter 24 again. During the lifting process, the balance detector 28 can detect the balance of the truss 26 to avoid deviation.
