A lifting device for the construction of an ultra-large cantilever steel structure

Abstract

This utility model relates to the field of ultra-large cantilever steel structures, specifically to a lifting device for the construction of ultra-large cantilever steel structures. It includes a support column for supporting the entire lifting device and a support frame fixed above the support column for mounting the lifting device. A drive motor is fixedly installed on the rear side of the support frame. This utility model's lifting device for ultra-large cantilever steel structures allows for adjustment by activating electric push rod switches on the outer sides of both ends of the support frame according to the length of the ultra-large cantilever steel structure. This pushes the piston rod and the moving frame to extend and retract. The extension and retraction of the moving frame moves internal rollers, and steel strands are sleeved on the outside of the rollers. As the rollers move, the steel strands unfold, thereby adjusting the distance between the two sets of steel strands. Then, the steel strands are suspended from the outside of the ultra-large cantilever steel structure by anti-detachment hooks below them. This adjustment not only regulates the distance between the two sets of steel strands but also strengthens the overall lifting support.

Description

Technical Field

[0001] This utility model relates to the field of ultra-large cantilever steel structures, specifically to a lifting device for the construction of ultra-large cantilever steel structures. Background Technology

[0002] The super-large cantilever steel structure is a large steel structure system with significant cantilever characteristics, while the lifting device for super-large cantilever steel structure construction is a special equipment used in the construction of high-rise buildings or large public facilities to lift the cantilever steel structure to the design position.

[0003] Traditional lifting devices for the construction of ultra-large cantilever steel structures cannot balance and distribute the force according to the length of the cantilever steel structure. As a result, the distance between the steel strands of the lifting device cannot be adjusted according to the length of the cantilever steel structure during the lifting process, which leads to poor force distribution and easy tilting.

[0004] Therefore, it is necessary to invent a lifting device for the construction of ultra-large cantilever steel structures to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a lifting device for the construction of ultra-large cantilever steel structures. By opening the electric push rod switches on the outer sides of both ends of the support frame according to the length of the ultra-large cantilever steel structure, the piston rod and the moving frame are pushed to extend and retract. When the moving frame extends and retracts, it drives the internal rollers to move. Steel strands are sleeved on the outside of the rollers. As the rollers move, the steel strands also unfold, thereby adjusting the distance between the two sets of steel strands. Then, the steel strands are suspended from the steel ropes bound to the outside of the ultra-large cantilever steel structure by anti-detachment hooks below them. This adjustment not only adjusts the distance between the two sets of steel strands but also strengthens the overall lifting support force. This solves the problem mentioned in the background art of traditional lifting devices for ultra-large cantilever steel structure construction, which cannot balance and distribute the force according to the length of the cantilever steel structure. Consequently, during the lifting process, the distance between the steel strands of the lifting device cannot be adjusted according to the length of the cantilever steel structure, resulting in an unbalanced force distribution and a tendency to tilt.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a lifting device for the construction of an ultra-large cantilever steel structure, including a support column for supporting the entire construction lifting device;

[0007] A support frame, fixed above a support column, is used to load a lifting device. A drive motor is fixedly installed on the rear side of the support frame. A first winder is fixedly connected to the output end of the drive motor. A second winder is rotatably connected inside the support frame. Steel strands are wound around the outside of the first and second winders. An anti-detachment hook is fixedly connected to the lower end of the steel strands.

[0008] A reciprocating rod is rotatably connected to both sides inside the support frame and is used to drive the moving block. The moving block is externally threaded onto the reciprocating rod. Fixed plates are fixedly connected to both sides inside the support frame, and the fixed plates are located on both sides of the moving block.

[0009] A sliding rod is fixed to the outside of a fixed plate. A movable frame is slidably connected to the outside of the sliding rod. A roller is rotatably connected inside the movable frame. Electric push rods are fixedly installed on both sides of the support frame. A piston rod is slidably connected inside the electric push rod.

[0010] Preferably, a first spur gear is fixedly connected to the rear side of the first winding device, a second spur gear is meshed with the first spur gear, and the second winding device is fixedly connected to the second spur gear.

[0011] Preferably, a servo motor is fixedly installed at the front end of the support frame, a first bevel gear assembly is fixedly connected to the output end of the servo motor, a transmission rod is fixedly connected inside the first bevel gear assembly, a second bevel gear assembly is fixedly connected to both ends of the transmission rod, and one end of the reciprocating rod is fixedly connected to the second bevel gear assembly.

[0012] Preferably, the front two sides of the support frame are fixedly connected to the fixed sleeves, and the transmission rod is rotatably connected to the fixed sleeves.

[0013] Preferably, the movable frame is slidably connected to the support frame, and the outside of the movable frame is fixedly connected to one end of the piston rod.

[0014] Preferably, the steel strand passes through the inside of the moving block and is sleeved on the outside of the roller.

[0015] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0016] By using a support frame, a movable frame, rollers, electric push rods, piston rods, steel strands, and anti-detachment hooks, the lifting section can be adjusted according to the length of the super-large cantilever steel structure. This not only disperses the balancing force but also increases the lifting force. By opening the electric push rod switches on both sides of the support frame according to the length of the super-large cantilever steel structure, the piston rod and movable frame are pushed to extend and retract. When the movable frame extends and retracts, it drives the internal rollers to move. The steel strands are sleeved on the outside of the rollers. As the rollers move, the steel strands also unfold, thereby adjusting the distance between the two sets of steel strands. Then, the anti-detachment hooks below the steel strands are used to suspend them from the steel ropes tied to the outside of the super-large cantilever steel structure. This adjustment not only adjusts the distance between the two sets of steel strands but also strengthens the overall lifting support.

[0017] By configuring a drive motor, a first winding device, a first spur gear, a second spur gear, a second winding device, a servo motor, a first bevel gear assembly, a transmission rod, a fixed sleeve, a second bevel gear assembly, a reciprocating rod, and a moving block, the neatness of the steel strand during winding is improved, preventing the steel strand from tangling together outside the first and second winding devices, thus avoiding wear and damage. When the drive motor switch is turned on, causing the first winding device to rotate, the first and second spur gears outside the first winding device mesh to drive the transmission. The rotation of the second spur gear then drives the second winding device to rotate, thus... The first and second winding devices rotate relative to each other to wind up the steel strand. During the winding process, the servo motor switch on the front side of the support frame is turned on, which drives the first bevel gear assembly to rotate. The rotation of the first bevel gear assembly drives the transmission rod and the second bevel gear assemblies at both ends to rotate. When the second bevel gear assembly rotates, it drives the reciprocating rod to rotate. The rotation of the reciprocating rod drives the external moving block to move back and forth. The steel strand passes through the moving block. Thus, when winding up the steel strand, the back-and-forth movement of the moving block allows the steel strand to be neatly wound up on the first and second winding devices.

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] This utility model provides, for example Figure 1-5 The lifting device for construction of an ultra-large cantilever steel structure shown includes a support column 1, which is used to support the entire construction lifting device.

[0028] Support frame 2 is fixed above support column 1 and is used to load lifting device. Drive motor 3 is fixedly installed on the rear side of support frame 2. First winder 4 is fixedly connected to the output end of drive motor 3. Second winder 7 is rotatably connected inside support frame 2. Steel strand 21 is wound around the outside of first winder 4 and second winder 7. Anti-detachment hook 22 is fixedly connected to the lower end of steel strand 21.

[0029] The reciprocating rod 13 is rotatably connected to both sides inside the support frame 2 and is used to drive the moving block 14. The moving block 14 is threadedly connected to the outside of the reciprocating rod 13. The fixing plate 15 is fixedly connected to both sides inside the support frame 2. The fixing plate 15 is located on both sides of the moving block 14.

[0030] A sliding rod 16 is fixed to the outside of the fixed plate 15. A movable frame 17 is slidably connected to the outside of the sliding rod 16. A roller 18 is rotatably connected inside the movable frame 17. Electric push rods 19 are fixedly installed on both sides of the support frame 2. A piston rod 20 is slidably connected inside the electric push rod 19. By opening the switch of the electric push rod 19 on both sides of the support frame 2 according to the length of the super-large cantilever steel structure, the piston rod 20 and the movable frame 17 are pushed to extend and retract. When the movable frame 17 extends and retracts, it drives the internal roller 18 to move. A steel strand 21 is sleeved on the outside of the roller 18. As the roller 18 moves, the steel strand 21 also unfolds, thereby adjusting the distance between the two sets of steel strands 21. Then, the steel strand 21 is suspended from the outside of the steel rope tied to the outside of the super-large cantilever steel structure by the anti-detachment hook 22 below it. This adjustment not only adjusts the distance between the two sets of steel strands 21, but also strengthens the overall lifting support.

[0031] like Figure 2 and Figure 3As shown, a first spur gear 5 is fixedly connected to the rear side of the first winding device 4, and a second spur gear 6 is meshed with the first spur gear 5. The second winding device 7 is fixedly connected to the second spur gear 6. When the drive motor 3 is turned on and the first winding device 4 is driven to rotate, the first spur gear 5 and the second spur gear 6 outside the first winding device 4 mesh to drive the second winding device 7 to rotate, so that the first winding device 4 and the second winding device 7 rotate relative to each other to wind up the steel strand 21.

[0032] like Figure 2 and Figure 4 As shown, a servo motor 8 is fixedly installed at the front end of the support frame 2. The output end of the servo motor 8 is fixedly connected to a first bevel gear assembly 9. A transmission rod 10 is fixedly connected inside the first bevel gear assembly 9. The two ends of the transmission rod 10 are fixedly connected to second bevel gear assemblies 12. One end of the reciprocating rod 13 is fixedly connected to the second bevel gear assembly 12. By turning on the switch of the servo motor 8 on the front side of the support frame 2, the first bevel gear assembly 9 is driven to rotate. The rotation of the first bevel gear assembly 9 drives the transmission rod 10 and the second bevel gear assemblies 12 at both ends to rotate. When the second bevel gear assembly 12 rotates, it drives the reciprocating rod 13 to rotate. The rotation of the reciprocating rod 13 drives the external moving block 14 to move back and forth. The steel strand 21 passes through the moving block 14. Thus, when the steel strand 21 is wound up, the moving block 14 moves back and forth, allowing the steel strand 21 to be neatly wound up on the first winding device 4 and the second winding device 7.

[0033] like Figure 4 As shown, fixed sleeves 11 are fixedly connected to the front two sides of the support frame 2. The transmission rod 10 is rotatably connected to the fixed sleeves 11. When the transmission rod 10 rotates, the external fixed sleeves 11 enhance the stability of the transmission rod 10 during rotation.

[0034] like Figure 2 and Figure 5 As shown, the movable frame 17 is slidably connected to the support frame 2. The outside of the movable frame 17 is fixedly connected to one end of the piston rod 20. By opening the electric push rods 19 on both sides of the support frame 2, the internal piston rod 20 and the movable frame 17 at one end are pushed to move within the support frame 2, thereby adjusting the distance between the steel strands 21 on both sides.

[0035] like Figure 1 and Figure 2 As shown, the steel strand 21 passes through the inside of the moving block 14 and is sleeved on the outside of the roller 18. When the first winder 4 and the second winder 7 wind the steel strand 21, the roller 18 facilitates the winding of the steel strand 21. At the same time, the steel strand 21 passing through the moving block 14 can enhance the stability of the winding of the steel strand 21.

[0036] The working principle of this utility model is as follows: First, connect the external power supply. When it is necessary to lift the super-large cantilever steel structure during construction, adjust the distance between the two sets of steel strands 21 according to the length of the super-large cantilever steel structure to enhance the stability of the lifting. By turning on the electric push rod 19 switch on both sides of the support frame 2, the piston rod 20 and the moving frame 17 are pushed to extend and retract. When the moving frame 17 extends and retracts, it drives the internal roller 18 to move. The steel strands 21 are sleeved on the outside of the roller 18. As the roller 18 moves, the steel strands 21 also unfold, thereby adjusting the distance between the two sets of steel strands 21. Then, the anti-detachment hook 22 below the steel strands 21 is used to suspend them from the steel rope tied to the outside of the super-large cantilever steel structure. This adjustment not only adjusts the distance between the two sets of steel strands 21, but also strengthens the overall lifting support. After suspending the super-large cantilever steel structure, turn on the drive motor 3 switch on the rear side of the support frame 2 to drive the first winding device 4 to rotate. The first spur gear 5 on the outside of the first winding device 4 is used to... The first winder 4 and the second winder 7 rotate in conjunction with the second spur gear 6, causing the first winder 4 and the second winder 7 to rotate relative to each other and wind up the steel strand 21. During the winding process, the servo motor 8 on the front side of the support frame 2 is switched on, causing the first bevel gear assembly 9 to rotate. The rotation of the first bevel gear assembly 9 drives the second bevel gear assemblies 12 at both ends of the transmission rod 10 to rotate. When the second bevel gear assembly 12 rotates, it drives the reciprocating rod 13 to rotate. The rotation of the reciprocating rod 13 drives the external moving block 14 to move back and forth. The steel strand 21 passes through the moving block 14. Thus, when winding up the steel strand 21, the moving block 14 moves back and forth, allowing the steel strand 21 to be neatly wound up on the first winder 4 and the second winder 7. After that, the super-large cantilever steel structure is lifted up by winding up the steel strand 21. Then, the two ends of the super-large cantilever steel structure can be welded or threaded to the building for installation. In this way, the use of the lifting device for the construction of the super-large cantilever steel structure is completed.

[0037] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
