[0020] 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 ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0021] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but rather merely represents selected embodiments of the present invention. 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.
[0022] like Figure 1As shown, the utility model provides a scaffolding steel pipe straightening device, including a main frame 10, a first support frame, a second support frame and a drag assembly 40. The main frame 10 includes two parallel main keel frames 11, two secondary keel frames 12 are welded to the top ends of the main keel frames 11 to form a rectangular frame, a third secondary keel frame 12 is welded to the bottom center of the main keel frame 11, and ground support columns 13 are welded to the four corners of the bottom of the rectangular frame. The bottom of the ground support column 13 is provided with a roller 14. The top of the main frame 10 is spaced apart. A first straightening frame 20 and a second straightening frame 30 are provided. The height of the first straightening frame 20 is higher than that of the second straightening frame 20. A dragging assembly 40 is provided on the front side of the main frame 10. The scaffolding steel pipe straightening device is provided with rollers 14 at the bottom, which can be freely moved to switch sites to improve work efficiency. During straightening, the first straightening frame 20 and the second straightening frame 30 cooperate to perform straightening work based on the lever principle. The device has high safety performance and low cost investment, can simply complete steel pipe straightening, and has outstanding practicality in small-scale projects.
[0023] It should be noted that the roller 14 is a Forma wheel with a brake structure to ensure that the frame can limit its movement when it is put into use, thereby increasing the stability of the steel pipe when it is straightened.
[0024] like Figure 2 As shown, the first straightening frame 20 includes two vertical poles 21 welded to the top of the main keel frame 11, and a mounting frame 22 is arranged between the two vertical poles 21. The side of the mounting frame 22 is a U-shaped structure with a number of threaded holes on both sides. The mounting frame 22 and the vertical poles 21 are fixed by bolts. A reinforcing rib 2202 is provided at the center of the inner wall of the mounting frame 22 to increase the strength of the mounting frame 22 so that it maintains strong stability during the force application process on the top of the first straightening frame 20. Two partition plates 2201 are equally divided in the middle of the inner side of the mounting frame 22, and a first roller 23 is provided between the two partition plates 2201. A second roller 24 is provided between any partition plate 2201 and the adjacent side wall of the mounting frame 22.
[0025] In this embodiment, the two second rollers 24 are inclined toward the direction of the first roller 23, and the first roller 23 is parallel to the bottom of the mounting frame 22. The three rollers form an inward-gathering structure, which can keep the steel pipe relatively fixed during straightening, avoiding random movement on the rollers, which is not conducive to straightening.
[0026] As a preferred embodiment, the surfaces of the first roller 23 and the second roller 24 are provided with a rubber layer, which can further enhance the friction of the steel pipe on the roller, preventing it from moving arbitrarily when subjected to straightening force, thereby affecting the straightening effect and progress. At the same time, the material of the rubber layer is selected to be hard rubber, such as fluororubber. This is a key stress point, and the surface of the roller will be frequently squeezed, so it is necessary to select this kind of rubber with high hardness, wear resistance and corrosion resistance.
[0027] like Figure 3 As shown, the second straightening frame 30 includes two diagonal braces 31, and a right-angle notch 3101 is opened at the bottom of the diagonal brace 31. The right-angle notch 3101 is embedded in the right-angled surface on the inner side of the top of the main keel frame 11 and is welded and fixed. The right-angle notch 3101 can increase the contact area between the diagonal brace 31 and the main keel frame 11, ensuring that the welding quality is stronger. A cross bar 32 is welded to the top of the two diagonal braces 31, and a resistance plate 33 is provided at the bottom of the cross bar 32. Since the tubular parts used in this straightening device are all hollow steel materials, this cross bar 32 is a key force point. If force is directly applied here, there is a risk of it being squeezed and deformed, causing damage to the structural strength. Therefore, a resistance plate 33 is provided to protect the cross bar 32 from damage. The material of the resistance plate 33 is preferably steel-titanium alloy, which has relatively low cost and high hardness, and can ensure that it will not be squeezed and deformed during use.
[0028] As a preferred embodiment, a plurality of rubber strips 34 are linearly and equally divided at the bottom of the resistance plate 33. The rubber strips 34 can ensure that the steel pipe can not shake freely when subjected to force here. Combined with the structure of the first straightening frame 20, the stability during the straightening process is ensured.
[0029] like Figure 4 As shown, the towing assembly 40 includes a connecting column 41 welded at the bottom center of the secondary keel frame 12 on the front side, and a docking plate 42 is welded to the bottom of the connecting column 41. It also includes a towing rod 44 and a sleeve 43. The sleeve 43 is sleeved on the bottom end of the towing rod 44, and the outer walls of the two are provided with through holes of the same size near the bottom end, and a pin is provided between the docking plate 42 and the through hole.
[0030] In this embodiment, an adsorption magnet 45 is provided at the front center of the front secondary keel frame 12, and the sleeve 43 is made of iron or iron alloy. When the drag rod 44 is perpendicular to the main frame 10, the sleeve 43 and the adsorption magnet 45 are magnetically attracted.
[0031] In the embodiment, when in use, the Forma wheel at the bottom of the straightening device is locked to fix it to the ground, and at the same time, the drag rod 44 is retracted, and the sleeve 43 is attracted by the magnetic force of the adsorption magnet to fix it in the vertical direction. At this time, the steel pipe with the straightening scaffolding is lowered from between the first straightening frame 20 and the second straightening frame 30, and the first roller 23 on the first straightening frame 20 is used as a fulcrum, and the contact plate 33 on the second straightening frame is used as a pry point. The bent part is placed on the fulcrum to manually straighten it. The structure has high safety, simple operation, and few requirements for the spatial environment. It can be moved according to the work needs, can be used continuously and multiple times, and has good economic benefits.
[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.
