[0002] In the field of construction, scaffolding is a key part of the supporting structure, and its stability and safety are directly related to the smooth progress of the entire project. Currently, the straightening of scaffolding steel pipes generally relies on large-scale electric mechanical equipment. With its powerful power output and automated processing capabilities, this type of equipment can efficiently and accurately complete the straightening operation of steel pipes, significantly improving construction efficiency and quality.

DETAILED DESCRIPTION
[0021] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings 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 a person of ordinary skill in the art without creative effort are within the scope of protection of the present invention.
[0023] like Figure 1 As shown, the utility model provides a hand-cranked scaffolding straightening device, including a main frame 10, the main frame 10 includes a horizontal channel steel frame 11 and a vertical channel steel frame 12 arranged on the rear side of the top thereof, a diagonal bracing channel steel 13 is arranged between the vertical channel steel frame 12 and the horizontal channel steel frame 11, a first connecting member 14 is arranged between the horizontal channel steel frame 11 and the diagonal bracing channel steel 13, a second connecting member 15 is arranged on the side of the horizontal channel steel frame 11 away from the first connecting member 14, a third connecting member 16 is arranged between the diagonal bracing channel steel 13 and the vertical channel steel, the horizontal channel steel frame 11 also includes a horizontal channel steel a1101 and a horizontal channel steel b1102, the horizontal channel steel a1101 and the horizontal channel steel A functional channel steel frame 20 is provided on the steel b1102, and a manual straightening assembly 30 is provided on the functional channel steel frame 20. The vertical channel steel frame 12 includes vertical channel steel a1201 on both sides and a vertical channel steel frame 12b in the middle. The vertical channel steel frame 12a is provided with a steel pipe side hanger 40. The two-stage spur gear reducer structure used in the reduction box 31 in the manual straightening assembly 30 allows construction workers to easily straighten the bent steel pipe. When in use, the bent steel pipe is hung on the two steel pipe side hangers 40, one hand holds the steel pipe, and the outward bend of the steel pipe is directed to the straightening top plate 34, and the other hand turns the rocker 3102. This method is flexible and highly maneuverable. At the same time, the two-stage spur gear reducer structure has the effect of saving effort, making it suitable for construction environments with low demand, constant environmental power supply, and small space.
[0024] In this embodiment, the first connecting member 14 and the second connecting member 15 extend toward the bottom of the horizontal channel steel frame 11, and the distance from the bottom of the two to the bottom of the horizontal channel steel frame 11 is the same. The first connecting member 14 and the second connecting member 15 not only enhance the stability of the channel steel connection between the main frames 10, but also serve as foot supports.
[0025] like Figure 3 As shown, a right-angle reinforcement block 23 is also provided at the connection between the functional channel steel frame 20 and the horizontal channel steel a1101 and the horizontal channel steel b1102. Two first side hangers 21 are provided in the horizontal direction on one side of the functional channel steel frame 20, and two second side hangers 22 are provided at the same position at the bottom of the first side hanger 21. A square hole 2101 is provided on the first side hanger 21, and a round hole 2201 is provided on the second side hanger 22.
[0026] like Figure 3-4 As shown, the manual straightening assembly 30 includes a reduction gear box 31, which is arranged between two channel steels on the functional channel steel frame 20. A movable groove 3101 is opened on one side of the top of the reduction gear box 31, and a driven wheel 3104 is movably arranged between the inner side walls thereof. The top of the driven wheel 3104 extends to the outside of the movable groove 3101, and also includes a rocker 3102. The output shaft of the rocker 3102 passes through one side of the box body to the inside, and a driving wheel 3103 is arranged on its output shaft, and the driving wheel 3103 is engaged with the driven wheel 3104.
[0027] In this embodiment, the manual straightening assembly 30 also includes a rack 32, an auxiliary rod 33 and a straightening top plate 34. A first docking sleeve 3401 and a second docking sleeve 3402 are respectively provided on one side of the straightening top plate 34. One end of the rack 32 is inserted into the first docking sleeve 3401, and one end of the auxiliary rod 33 is inserted into the second docking sleeve 3402, and both are fixed by bolts. The rack 32 is slidably set in the two square holes 2101, and the rack 32 is engaged with the driven wheel 3104. The auxiliary rod 33 is slidably set in the round hole 2201. The auxiliary rod 33 plays a role in stabilizing the horizontal movement of the rack 32 and the straightening top plate 34.
[0028] As a preferred embodiment, the side of the straightening top plate 34 is provided with an anti-slip layer, specifically made of hard rubber, which can reduce the deformation caused by squeezing when straightening the steel pipe, thereby reducing the strength of the steel pipe in subsequent use.
[0029] In this embodiment, the width of the straightening top plate 34 is smaller than the spacing between the two vertical channel steels b1202. Since the metal material itself has a certain stress, there is a certain rebound during the straightening process. The gap between the two vertical channel steels b1202 allows the straightening top plate 34 to press the steel pipe straight and then move excessively toward the gap direction to offset the stress rebound of the steel pipe.
[0030] like Figure 5 As shown, the steel pipe side hanging 40 includes a connecting block 41, a hook 42 is provided near the middle of one side of the connecting block 41, and a reinforcing rib 43 is provided between the bottom of the hook 42 and the connecting block 41. The reinforcing rib 43 can be used to increase the load-bearing capacity of the hook 42 and increase its structural strength. The side of the connecting block 41 away from the hook 42 is connected to a positioning block by bolts, and the positioning block is slidably set in the gap of the vertical channel steel a1201. It can be fixed or removed by adjusting the bolts on the connecting block 41. In this embodiment, the height of the steel pipe side hanging 40 on the vertical channel steel a1201 can be adjusted according to the operating habits of the construction personnel, so that it has a better operating experience.
[0031] Specifically, the working principle of this hand-cranked scaffolding straightening device is as follows: when in use, the bent steel pipes are hung on two steel pipe side hangers 40 respectively, and the steel pipes are held with one hand so that the outward bent part points to the straightening top plate 34. At this time, the rocker 3102 is rotated, and the active wheel 3103 drives the driven wheel 3104, and then drives the rack 32, so that the straightening top plate 34 does not straighten the bent steel pipes. During this process, the auxiliary rod 33 increases the stability of the horizontal movement of the rack 32 and the modulation top plate. Through the above structure, the problem that the existing large-scale steel pipe straightening equipment is not suitable for small-scale building construction environments with a limited number of steel pipes to be straightened, and it relies on electric drive, is bulky and inconvenient to carry, which seriously affects the flexibility and efficiency of construction is solved.
[0032] The above further describes the present invention with the help of specific embodiments, but it should be understood that the specific description here should not be construed as limiting the essence and scope of the present invention. Various modifications made to the above embodiments by ordinary technicians in this field after reading this specification are all within the scope of protection of the present invention.
