Description

Technical Field

[0001] This utility model relates to the field of scaffolding technology, and in particular to a scaffolding steel pipe straightening mechanism. Background Technology

[0002] Scaffolding steel pipes are commonly used tools for working at heights in construction. Through repeated use in multiple projects, they will be damaged and deformed during use. If no appropriate measures are taken for severely deformed steel pipes, they will become unusable or may cause safety accidents during use.

[0003] Currently, existing scaffolding steel pipe straightening devices utilize two pressure rollers for straightening. During the straightening process, large cement lumps adhering to the surface of the steel pipe fall off as the pipe is squeezed. However, the upper and lower pressure rollers can only contact the upper and lower surfaces of the steel pipe, resulting in incomplete removal of cement lumps from the sides, affecting the straightening effect and subsequent installation and use. Furthermore, they lack the ability to remove rust from the surface. Therefore, to better achieve the removal of cement lumps and rust from the surface of scaffolding steel pipes, promote technological progress in the industry, and enhance core technological competitiveness, this application proposes a new implementation scheme for scaffolding steel pipe straightening devices that differs from existing technologies. Utility Model Content

[0004] The purpose of this utility model is to solve the problems of incomplete cleaning of cement blocks and rust on the surface of existing scaffolding, and to propose a scaffolding steel pipe straightening mechanism.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A scaffolding steel pipe straightening mechanism includes a workbench and a straightening assembly. A third motor is fixedly connected to one side of the workbench, and a fourth gear is keyed to the output end of the third motor. Two mounting brackets are fixedly connected to the top of the workbench. A first rotating tube and a second rotating tube are rotatably mounted on one side of each mounting bracket via interlocking bearings. An installation tube is provided between the first and second rotating tubes. A third gear is fixedly connected to the outer circumference of the installation tube. A toothed belt drives the fourth gear and the third gear. Multiple connecting rods are fixedly connected between the first rotating tube and the installation tube, and between the second rotating tube and the installation tube. Multiple support frames are fixedly connected to the inner circumference of the first rotating tube. Rollers are rotatably connected between the inner walls of the two sides of the support frames. Multiple protrusions are integrally formed on the outer circumference of the rollers. Two threaded rods are threadedly connected to the circumference of the second rotating tube. A rotating handle is fixedly connected to one end of each threaded rod, and an annular plate is rotatably connected to the other end of each threaded rod. A wire brush is fixedly connected to the inner side of the annular plate.

[0007] Furthermore, the straightening assembly includes multiple upper pressure rollers and multiple lower pressure rollers. A mounting plate is fixedly connected to the top of the worktable. The upper pressure rollers and lower pressure rollers are rotatably connected to one side of the mounting plate. One end of two upper pressure rollers is fixedly connected to a first gear, and one end of two lower pressure rollers is fixedly connected to a second gear.

[0008] Furthermore, a first motor is embedded in one side of the workbench, and the output end of the first motor is fixedly connected to one end of one of the upper pressure rollers.

[0009] Furthermore, a second motor is embedded in one side of the workbench, and the output end of the second motor is fixedly connected to one end of another upper pressure roller.

[0010] Furthermore, a collection box is slidably inserted into one side of the workbench, and a handle is fixedly connected to one side of the outer wall of the collection box.

[0011] Furthermore, the top of the workbench is provided with a discharge trough, and the collection box is located below the discharge trough.

[0012] Furthermore, a control panel is fixedly connected to one side of the workbench, and the control panel is connected to the first motor, the second motor, and the third motor via wires.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. Driven by the third motor and the toothed belt, the mounting tube is rotated, which in turn drives the first rotating tube to rotate. This causes the rollers to roll and squeeze on the steel pipe, thereby removing the cement lumps from the steel pipe and completely removing them.

[0015] 2. Driven by the first motor and the meshing of the first and second gears, the upper and lower pressure rollers are rotated, thereby conveying the steel pipe forward. The upper and lower pressure rollers then squeeze the steel pipe, thus straightening it, saving time and effort.

[0016] 3. By rotating the second rotating tube driven by the installation tube, the wire brush rubs against the steel pipe, thereby wiping away the dust on the outer surface of the steel pipe and improving the cleaning effect. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figures 1-5 A scaffolding steel pipe straightening mechanism includes a workbench 1 and a straightening assembly. A third motor 23 is fixed to one side of the workbench 1 by bolts, and a fourth gear 24 is keyed to the output end of the third motor 23.

[0025] Two mounting brackets 10 are welded to the top of the workbench 1. A first rotating tube 11 and a second rotating tube 12 are rotatably mounted on one side of the two mounting brackets 10 via interlocking bearings. An installation tube 14 is provided between the first rotating tube 11 and the second rotating tube 12. Multiple connecting rods 13 are welded between the first rotating tube 11 and the installation tube 14, and between the second rotating tube 12 and the installation tube 14.

[0026] The outer circumference of the mounting tube 14 is fixed with a third gear 15 by bolts. The fourth gear 24 is connected to the third gear 15 by a toothed belt 25. The tolerance standard of the third gear 15, the fourth gear 24 and the toothed belt 25 is h7 / g6, and there will be no loosening.

[0027] The inner circumference of the first rotating tube 11 is fixed with multiple evenly distributed support frames 16 by bolts. Rollers 17 are rotatably connected between the inner walls of the two sides of the support frames 16. Multiple protrusions 18 are integrally formed on the outer circumference of the rollers 17. The rollers 17 and protrusions 18 are made of tungsten carbide. Driven by the third motor 23 and driven by the toothed belt 25, the mounting tube 14 is rotated, thereby driving the first rotating tube 11 to rotate. This causes the rollers 17 to roll and squeeze on the steel pipe, thereby removing the cement blocks on the steel pipe.

[0028] The second rotating tube 12 has two threaded rods 19 connected by a circumferential thread. One end of the threaded rod 19 is welded with a rotating handle 20, and the other end of the threaded rod 19 is rotatably connected to an annular plate 21. A wire brush 22 is fixed to the inner side of the annular plate 21 by bolts. Turning the rotating handle 20 drives the threaded rod 19 to rotate, thereby driving the annular plate 21 to move, so that the wire brush 22 comes into contact with the steel pipe for subsequent cleaning of the steel pipe.

[0029] The straightening assembly includes multiple upper pressure rollers 9 and multiple lower pressure rollers 901. A mounting plate 6 is welded to the top of the workbench 1. The upper pressure rollers 9 and lower pressure rollers 901 are rotatably connected to one side of the mounting plate 6. One end of two upper pressure rollers 9 is fixed with a first gear 8 by bolts, and one end of two lower pressure rollers 901 is fixed with a second gear 801 by bolts. A first motor 7 is embedded in one side of the workbench 1. The output end of the first motor 7 is fixedly connected to one end of one of the upper pressure rollers 9. Driven by the first motor 7 and by the meshing of the first gear 8 and the second gear 801, the upper pressure rollers 9 and lower pressure rollers 901 are rotated, thereby causing the steel pipe to be conveyed forward. The upper pressure rollers 9 and lower pressure rollers 901 then squeeze the steel pipe, thus performing a straightening operation on the steel pipe.

[0030] A second motor 701 is embedded on one side of the workbench 1. The output end of the second motor 701 is fixedly connected to one end of another upper pressure roller 9. The second motor 701 drives the upper pressure roller 9 and the lower pressure roller 901 connected to it to rotate, thereby conveying the cleaned steel pipe away.

[0031] A collection box 3 is slidably inserted into one side of the workbench 1. A handle 4 is fixed to the outer wall of one side of the collection box 3 by bolts. A discharge chute 2 is provided on the top of the workbench 1. The collection box 3 is located below the discharge chute 2. The cement blocks and dust that are cleaned off fall from the discharge chute 2 into the collection box 3 for collection.

[0032] A control panel 5 is fixed to one side of the workbench 1 by bolts. The control panel 5 is connected to the first motor 7, the second motor 701 and the third motor 23 by wires.

[0033] The working principle of this embodiment is as follows: In use, firstly, the steel pipe is placed between the upper pressure roller 9 and the lower pressure roller 901, and the steel pipe is passed through the first rotating tube 11, the mounting tube 14, and the second rotating tube 12. Then, the rotating handle 20 is turned to drive the threaded rod 19 to rotate, thereby driving the annular plate 21 to move, so that the wire brush 22 comes into contact with the steel pipe. Next, the first motor 7 is started by controlling the control panel 5. Under the drive of the first motor 7 and the meshing of the first gear 8 and the second gear 801, the upper pressure roller 9 and the lower pressure roller 901 are driven to rotate, thereby causing the steel pipe to be conveyed forward. Then, the upper pressure roller 9 and the lower pressure roller 901 are used to squeeze the steel pipe, thus straightening the steel pipe.

[0034] When the steel pipe is delivered to the first rotating pipe 11, the third motor 23 is started by controlling the control panel 5. Driven by the third motor 23 and the transmission action of the toothed belt 25, the installation pipe 14 is rotated, thereby driving the first rotating pipe 11 to rotate, which in turn causes the roller 17 to roll and squeeze on the steel pipe, thereby removing the cement block on the steel pipe.

[0035] When the steel pipe is conveyed to the second rotating pipe 12, the installation pipe 14 drives the second rotating pipe 12 to rotate, thereby causing the wire brush 22 to rub against the steel pipe, thus wiping away the dust on the outer surface of the steel pipe. The cleaned cement blocks and dust fall from the discharge chute 2 into the collection box 3 for collection. Finally, the control panel 5 controls the second motor 701 to start, and the second motor 701 drives the upper pressure roller 9 and lower pressure roller 901 connected to it to rotate, thereby conveying the cleaned steel pipe away.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
