A construction hoistable ring scaffold device for a tank

Abstract

The application belongs to the technical field of liftable ring-shaped scaffolds, and discloses a liftable ring-shaped scaffold device for tank body construction, which comprises a steel pipe fastener, and the outer surface of the steel pipe fastener is threadedly connected with a safety net. When the staff installs the ring-shaped inner cantilevered flap, the staff only needs to paste the ring-shaped inner cantilevered flap on the surface of the tank body and push the ring-shaped inner cantilevered flap towards the tank body so that the compression spring is contracted to form a reaction force on the tank body. The internally arranged extrusion rollers are arranged in multiple groups in cross arrangement. The extrusion rollers themselves are mutually pasted with the tank body. The staff only needs to rotate the rotating shaft so that the bent anti-unhooking hook is not limited to limiting the ring, and the extrusion rollers are relaxed to easily lift the hanging body together with the ring-shaped inner cantilevered flap, thereby achieving the purpose that the staff can loosen the ring-shaped inner cantilevered flap without approaching the edge of the hanging body.

Description

Technical Field

[0001] This invention belongs to the technical field of liftable ring scaffolding, specifically a liftable ring scaffolding device for tank construction. Background Technology

[0002] Scaffolding refers to various supporting structures erected on construction sites to facilitate worker operations and vertical and horizontal transportation. It's a common term in the construction industry, referring to scaffolding used on construction sites for exterior walls, interior decoration, or in areas with high ceilings where direct construction is impossible. Its main purpose is for workers to move up and down, for maintaining safety netting, and for installing components at heights; simply put, it's setting up a frame. Scaffolding materials typically include bamboo, wood, steel pipes, or composite materials. Some projects also use scaffolding as formwork. Furthermore, it's widely used in advertising, municipal engineering, transportation and bridge construction, and mining. Scaffolding is used to lift objects or people of a certain weight to a designated height. In this process, it's crucial to consider the scaffolding's load-bearing capacity. Generally, from a mechanical perspective, the overall design of the scaffolding and the quality of its connections demonstrate its load-bearing capacity. Therefore, when selecting scaffolding, one should start by considering the rationality of its overall design to choose scaffolding with sufficient load-bearing capacity.

[0003] When the device is in use, painting or welding reinforcing columns involves lowering / raising the entire construction process layer by layer from top to bottom or bottom to top. After completing one layer, the chain hoist is moved to the next or next layer and hung at another horizontal height to continue the same construction work. During this process, the existing device requires loosening the connecting bolts on the surface of the inner cantilever flap. Because the connecting bolts are connected to the tank itself, workers need to operate close to the edge of the tank. This operation is not only cumbersome, but also dangerous due to its proximity to the edge of the hanging body. As a result, the device is inefficient and poses certain safety hazards during lifting operations.

[0004] In addition, after the scaffolding planks of the first floor are spliced ​​together, it is usually necessary to lay the scaffolding planks on the other side. At this time, the workers need to extend the uprights. Because the length of the uprights themselves is quite long, the workers need to rise to the connection point of the two uprights to complete the threaded connection between the two uprights. This is time-consuming and somewhat dangerous. Therefore, it is necessary to design a liftable ring scaffolding device for tank construction. Summary of the Invention

[0005] The purpose of this invention is to provide a liftable ring scaffolding device for tank construction, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a liftable circular scaffolding device for tank construction, comprising steel pipe couplers, a safety net threadedly connected to the outer surface of the steel pipe couplers, a spliced ​​circular scaffold board threadedly connected to the inner wall of the safety net, an upright threadedly connected to the inner wall of the spliced ​​circular scaffold board, an annular inner cantilever plate movably connected to the inner wall of the upright, a guide rail connected inside the annular inner cantilever plate, an integrated electric hoist connected to the inner wall of the upright, and a connecting shell fixedly connected to the surface of the annular inner cantilever plate. A functional compartment is connected to the upper surface of the outer shell. The inner wall of the annular inner flap is provided with multiple sets of extrusion rollers. Roller brackets are fixedly connected to both sides of the extrusion rollers. A movable column is fixedly connected to the bottom of the roller bracket. A limiting ring is fixedly connected to the surface of the movable column. A compression spring is connected to the end of the movable column away from the roller bracket. A limiting plate is connected to the middle of the interior of the functional compartment. Fixed rods are fixedly connected to both sides of the limiting plate. A rotating shaft is rotatably connected to the bottom of the inner wall of the functional compartment. A curved anti-disengagement hook is fixedly connected to the surface of the rotating shaft.

[0007] The surface of the upright is rotatably connected to a turntable. The bottom of the top upright is fixedly connected to a plug-in block. Limiting grooves are formed on both sides of the plug-in block. The top of the bottom upright is provided with a plug-in groove. The end of the turntable is fixedly connected to a first gear. A second gear is meshed with the first gear. A rotating rod is fixedly connected to the surface of the first gear away from the turntable. A transverse extension rod is fixedly connected to one side of the rotating rod. A first limiting post is fixedly connected to the upper surface of the transverse extension rod. A Z-shaped extension plate is fixedly connected to the surface of the second gear. A second limiting post is fixedly connected to the upper surface of the Z-shaped extension plate.

[0008] As a further technical solution of the present invention, a triangular brace can be installed inside the upright, and a tension sensor is installed at the position of the hook.

[0009] As a further technical solution of the present invention, a wall-mounted support is installed on the top of the upright, and a lifting bracket connected to the tank body is installed on one side of the wall-mounted support.

[0010] As a further technical solution of the present invention, the integrated electric hoist works by rotating in a ring, and the guide rail is threadedly connected to the tank body itself.

[0011] The integrated electric hoist drives the hanging body to be raised or lowered along the wall-mounted support through a ring rotation.

[0012] As a further technical solution of the present invention, the output end of the integrated electric hoist is connected to a lifting chain, the bottom of the lifting chain is connected to a positive hook, and the middle of the lifting chain is connected to a lifting bracket.

[0013] As a further technical solution of the present invention, the spliced ​​annular scaffold board and the annular inner cantilever board are both spliced ​​and installed, and the extrusion rollers are provided in multiple sets and arranged vertically in a crisscross pattern.

[0014] When the extrusion roller is installed, the internal compression spring is compressed when the extrusion roller is subjected to the reaction force of the tank, and the moving column is pushed backward. At this time, the curved anti-detachment hook will not limit the limiting ring on the surface of the moving column. However, when the extrusion roller has moved to the desired position, the compression spring releases the moving column, and the bottom of the limiting ring limits the movement between the curved anti-detachment hook and the moving column, preventing the moving column from falling off and ensuring the position of the extrusion roller.

[0015] As a further technical solution of the present invention, the end of the compression spring away from the moving column is connected to the inner wall of the functional compartment.

[0016] As a further technical solution of the present invention, there is a certain distance between the limiting piece and the rotating shaft to facilitate the curved anti-disengagement hook to rotate counterclockwise at a certain angle.

[0017] As a further technical solution of the present invention, the space between the rotating rod and the Z-shaped extension plate is larger than the bottom area of ​​the plug-in block, and the position of the rotating rod is located in the middle of the plug-in block after it is plugged in.

[0018] The operator rotates the turntable 90 degrees. At this time, the plug-in block is between the rotating rod and the Z-shaped extension plate. The 90-degree angle change makes the first and second limiting posts lateral towards the plug-in block.

[0019] As a further technical solution of the present invention, the first limiting post and the limiting groove cooperate with each other.

[0020] The beneficial effects of this invention are as follows:

[0021] 1. This invention, through the design of an annular inner flap, compression rollers, a limiting ring, a rotating shaft, and a curved anti-detachment hook, allows workers to easily lift the device by simply placing the annular inner flap against the tank surface and pushing it towards the tank, causing the compression spring to contract and generate a reaction force against the tank. The internal compression rollers are arranged in multiple crisscrossing groups, with the rollers themselves in contact with the tank. When the device is lifted, simply rotating the rotating shaft removes the curved anti-detachment hook from its position relative to the limiting ring, allowing the compression rollers to relax and easily lift the device along with the annular inner flap. This achieves the goal of loosening the annular inner flap without requiring workers to approach the edge of the device during lifting or lowering operations.

[0022] 2. This invention, through the design of plug-in blocks, plug-in slots, a turntable, a first limiting post, and a second limiting post, allows for efficient platform erection. When the platform needs to be further constructed, workers insert another set of uprights onto the top of the bottom uprights. To achieve rapid assembly, workers simply insert the designed plug-in blocks into the plug-in slots. Then, the turntable is rotated 90 degrees, placing the plug-in blocks between the rotating rod and the Z-shaped extension plate. This 90-degree angle change causes the first and second limiting posts to be laterally positioned towards the plug-in blocks. The first and second limiting posts, along with the limiting slots on both sides of the plug-in blocks, interlock to limit the movement between the upper and lower uprights, facilitating the upward assembly of the modular ring-shaped scaffolding boards. This streamlined platform construction, eliminating the cumbersome threaded connection process and increasing installation efficiency. Attached Figure Description

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Example 1

[0033] like Figures 1 to 5 As shown in the embodiment of the present invention, a liftable annular scaffolding device for tank construction includes a steel pipe coupler 1. A safety net 2 is threadedly connected to the outer surface of the steel pipe coupler 1. A spliced ​​annular scaffold board 3 is threadedly connected to the inner wall of the safety net 2. A vertical pole 4 is threadedly connected to the inner wall of the spliced ​​annular scaffold board 3. An annular inner cantilever flap 5 is movably connected to the inner wall of the vertical pole 4. A guide rail 6 is connected inside the annular inner cantilever flap 5. An integrated electric hoist 7 is connected to the inner wall of the vertical pole 4. A connecting shell 11 is fixedly connected to the surface of the annular inner cantilever flap 5. A functional compartment 12 is connected to the upper surface of the connecting shell 11. Multiple sets of compression rollers 13 are arranged on the inner wall of the annular inner cantilever flap 5. Roller supports 14 are fixedly connected to both sides of the compression rollers 13. A movable column 15 is fixedly connected to the bottom of the roller support 14. A limiting ring 16 is fixedly connected to the surface of the movable column 15. A compression spring 17 is connected to the end of the movable column 15 away from the roller support 14. The functional compartment 1... The inner middle of the 2 is connected to a limiting plate 18, and the two sides of the limiting plate 18 are fixedly connected to fixed rods 19. The bottom of the inner wall of the functional compartment 12 is rotatably connected to a rotating shaft 20, and the surface of the rotating shaft 20 is fixedly connected to a curved anti-disengagement hook 21. A triangular brace can be installed inside the upright 4. A tension sensor is installed at the position of the positive hook 9. A wall-mounted support is installed at the top of the upright 4. A lifting bracket 10 connected to the tank body is installed on one side of the wall-mounted support. The integrated electric hoist 7 works by rotating in a ring. The guide rail 6 is threadedly connected to the tank body itself. The output end of the integrated electric hoist 7 is connected to a lifting chain 8. The bottom of the lifting chain 8 is connected to a positive hook 9. The middle of the lifting chain 8 is connected to a lifting bracket 10. The spliced ​​ring scaffold board 3 and the ring inner lifting flap 5 are both spliced. Multiple sets of compression rollers 13 are arranged vertically in a cross pattern. The end of the compression spring 17 away from the moving column 15 is connected to the inner wall of the functional compartment 12.

[0034] Compared with existing technologies, the advantages are as follows: When the device is in use, the operator first sets up an operating platform on the outside of the tank using steel pipe couplers 1. Scissor bracing is installed on the outside of the steel pipe couplers 1. This operating platform is a certain distance from the wall. A spliced ​​ring-shaped scaffold board 3 is placed on the operating platform, followed by the installation of uprights 4 and guide rails 6. When the device needs to be pulled upwards or during installation, the operator needs to tighten or loosen the bolts inside the existing fitting flap. This operation is performed at a certain height and is somewhat dangerous, or the operation requires the device to be lifted upwards. The shorter the time required, the better. At this point, according to the set ring-shaped inner flap 5, when the operator installs the ring-shaped inner flap 5, they only need to attach the ring-shaped inner flap 5 to the surface of the tank and push the ring-shaped inner flap 5 towards the tank, causing the compression spring 17 to contract. The tank body generates a reaction force, and the internally installed extrusion rollers 13 are arranged in multiple sets in a crisscross pattern. The extrusion rollers 13 themselves are in contact with the tank body. When the hanging body is lifted, the rotating shaft 20 only needs to be rotated so that the curved anti-detachment hook 21 is no longer limited by the limiting ring 16, allowing the extrusion rollers 13 to relax, and the hanging body along with the annular inner lifting flap 5 can be easily lifted. When the extrusion rollers 13 are installed, when the extrusion rollers 13 are subjected to the reaction force of the tank body, the internal compression spring 17 is compressed, and the moving column 15 is pushed backward. At this time, the curved anti-detachment hook 21 will not limit the limiting ring 16 on the surface of the moving column 15. However, when the extrusion rollers 13 have moved to their current position, the compression spring 17 releases the moving column 15, and the bottom of the limiting ring 16 limits the movement between the curved anti-detachment hook 21, preventing the moving column 15 from falling off, while also ensuring the position of the extrusion rollers 13.

[0035] Example 2

[0036] like Figures 6 to 7As shown in the embodiment of the present invention, a liftable ring-shaped scaffolding device for tank construction includes a turntable 25 rotatably connected to the surface of the upright 4. A plug-in block 22 is fixedly connected to the bottom of the top upright 4, with limit grooves 23 on both sides of the plug-in block 22. A plug-in groove 24 is provided on the top of the bottom upright 4. A first gear 26 is fixedly connected to the end of the turntable 25, and a second gear 30 is meshed with the first gear 26. A rotating rod 27 is fixedly connected to the surface of the first gear 26 away from the turntable 25, and a transverse extension rod is fixedly connected to one side of the rotating rod 27. 28. A first limiting post 29 is fixedly connected to the upper surface of the transverse extension rod 28. A Z-shaped extension plate 31 is fixedly connected to the surface of the second gear 30. A second limiting post 32 is fixedly connected to the upper surface of the Z-shaped extension plate 31. There is a certain gap between the limiting plate 18 and the rotating shaft 20 to facilitate the curved anti-disengagement hook 21 to rotate counterclockwise at a certain angle. The space between the rotating rod 27 and the Z-shaped extension plate 31 is larger than the bottom area of ​​the plug-in block 22. The position of the rotating rod 27 is in the middle after the plug-in block 22 is plugged in. The first limiting post 29 and the limiting groove 23 cooperate with each other.

[0037] Compared with existing technologies, the advantages are as follows: Workers first erect an operating platform outside the tank using steel pipe couplers 1. Scissor bracing is installed on the outside of the steel pipe couplers 1. This operating platform is a certain distance from the wall. Interlocking ring-shaped scaffold boards 3 are placed on the operating platform, followed by the installation of uprights 4 and guide rails 6. When it is necessary to continue erecting the platform upwards, workers insert another set of uprights 4 onto the top of the bottom uprights 4. To achieve rapid filling, workers only need to insert the designed connector 22 into the connector. Inside the groove 24, the worker then rotates the turntable 25 ninety degrees. At this time, the plug block 22 is between the rotating rod 27 and the Z-shaped extension plate 31. The ninety-degree angle change makes the first limiting post 29 and the second limiting post 32 appear in a horizontal state towards the plug block 22. At this time, the first limiting post 29, the second limiting post 32 and the limiting grooves 23 on both sides of the plug block 22 are interlocked to limit the position between the upper upright 4 and the lower upright 4, making it convenient for the worker to assemble the spliced ​​ring scaffold board 3 upwards.

[0038] Working principle and usage process:

[0039] The device is first installed before use. Specifically, the operator first sets up an operating platform on the outside of the tank using steel pipe couplers 1. Scissor bracing is installed on the outside of the steel pipe couplers 1. This operating platform is a certain distance from the wall. A modular ring-shaped scaffold board 3 is placed on the operating platform, followed by the installation of uprights 4 and guide rails 6. When the device needs to be raised or lowered, simply rotate the rotating shaft 20 so that the curved anti-disengagement hook 21 is no longer limited by the limiting ring 16, allowing the squeezing roller 13 to loosen, thus easily lifting the hanging body along with the ring-shaped inner lifting flap 5. When the assembly needs to extend upwards, the worker only needs to insert the designed plug-in block 22 into the plug-in slot 24. Then, the worker rotates the turntable 25 ninety degrees. At this time, the plug-in block 22 is between the rotating rod 27 and the Z-shaped extension plate 31. The ninety-degree angle change makes the first limiting post 29 and the second limiting post 32 appear in a horizontal state towards the plug-in block 22. At this time, the first limiting post 29, the second limiting post 32 and the limiting slots 23 on both sides of the plug-in block 22 are interlocked to limit the distance between the upper and lower uprights 4.
