Description

Technical Field

[0001] The utility model relates to the technical field of engineering construction equipment, in particular to a scaffolding steel pipe straightening device adaptable to different apertures. Background Art

[0002] In the construction industry, scaffolding steel pipes are important materials for supporting and building construction platforms. However, during long-term use, steel pipes often bend and deform, especially after being exposed to the sun and rain, rust and corrosion, and the heavy pressure during construction, disassembly, and transportation. This not only affects the stability and safety of the scaffolding, but may also make the steel pipes unusable, resulting in economic losses. Therefore, it is particularly important to straighten and repair scaffolding steel pipes.

[0003] At present, the electric mechanical equipment used on construction sites is designed by combining mechanical transmission and computer technology and has a high degree of automation. However, in actual applications, mainstream electric straightening equipment can usually only adapt to the straightening of steel pipes of a single diameter. However, in actual construction, the diameters of scaffolding steel pipes often vary, which brings limitations to the use of electric straightening equipment. Utility Model Content

[0024] like Figure 1-4 As shown, the utility model provides a scaffolding steel pipe straightening device adapted to different apertures, comprising a workbench 10, a clamping roller assembly 20 and a correction assembly 30, the workbench 10 comprising two track channel steels 11, a plurality of reinforcing channel steels 12 being arranged between the track channel steels 11, a side platform 14 being arranged on the outer side of one of the track channel steels 11, the clamping roller assembly 20 comprising a fixed frame 21, a horizontal clamping roller 22 and a vertical clamping roller 23, the fixed frame 21 being arranged between the two track channel steels 11, the horizontal clamping roller 22 being arranged on the inner side of the fixed frame 21, and the vertical clamping roller 23 being arranged on the outer side of the fixed frame 21. The device is arranged on one side of the fixed frame 21, and has two clamping roller assemblies 20, which are respectively arranged between two track channel steels 11. A driving motor (40) is arranged on the side platform 14, and the output shaft of the driving motor 40 is engaged with the horizontal clamping roller 22 on one of the clamping roller assemblies 20. The correction assembly 30 is arranged on two reinforced channel steels 12 near the center of the workbench 10. When in use, the spacing of the horizontal clamping rollers 22 is adjusted by the hand wheel 2205, and the spacing of the vertical clamping rollers 23 is adjusted by the second screw 2304, so that the device can adapt to different steel pipe diameters.

[0025] like Figure 3 As shown, the fixed frame 21 includes two sliding bases 2101, a lower channel steel 2102 is connected between the two, an upper channel steel 2103 is arranged above the lower channel steel 2102, two side rails 2105 are connected between the top ends of any sliding base 2101 and the upper channel steel 2103, angle irons 2104 are respectively provided on the outer side of the side rails 2105 and the two ends of the upper channel steel 2103, and the sliding base 2101 is slidably set on the track channel steel 11.

[0026] In this embodiment, a sliding groove that engages with the track channel steel 11 is opened on one side of the bottom of the sliding base 2101, and a roller is provided at the bottom of the sliding base 2101 so that it can be slidably set on the track channel steel 11. A first screw 21011 is provided on the outer side of the sliding base 2101. The first screw 21011 is used to fix the fixed base at a specific position of the track channel steel 11. Through this movable and fixed method, the distance between the two clamping roller assemblies 20 can be adjusted as needed, so as to better straighten steel pipes of different lengths and different degrees of curvature.

[0027] In this embodiment, right-angle baffles 13 are provided at both ends of the workbench 10 to prevent the fixing frame 21 from sliding out of the range of the workbench 10 when adjusting, falling to the ground, or even hitting people in a construction accident.

[0028] In this embodiment, the horizontal clamping roller 22 includes a lower clamping roller 2201 movably set between two sliding bases 2101, a bearing seat 2202 is set on the outer side of the sliding base 2101, and the two ends of the lower clamping roller 2201 pass through the sliding base 2101 and are hinged to the bearing seat 2202. A slider bearing 2106 is set between any two side rails 2105, and an upper clamping roller 2203 is movably set between the two slider bearings 2106. A docking portion 21061 is set on the top of the slider bearing 2106. It also includes a lifting screw 2204, one end of the lifting screw 2204 is movably set on the docking portion 21061, and the other end thereof passes through the upper channel steel 2103 and is threadedly connected to the upper channel steel 2103. A handwheel 2205 is set at the top of the lifting screw 2204.

[0029] In this embodiment, the roller shaft of the lower clamping roller 2201 close to the driving motor 40 is connected to the output shaft of the driving motor 40 .

[0030] As a preferred embodiment, an anti-skid layer is provided inside the surface of the horizontal roller. Since the movement of the steel pipe is mainly driven by the friction between the horizontal clamping roller 22 and the steel pipe, the anti-skid layer is provided to increase the interaction force between the horizontal clamping roller 22 and the steel pipe.

[0031] In this embodiment, two hinged ears 2301 are provided on the side, and the same hinged ears 2301 are provided at the same position of the lower channel steel 2102 and the upper channel steel 2103. A rocker arm 2303 is hinged on the hinged ear 2301, and a side clamping roller 2305 is provided between the two rocker arms 2303 in the vertical direction. An adjustment plate 2302 is provided on the outer side of the upper channel steel 2103 near the hinged ear 2301, and a second screw rod 2304 is threadedly connected to the adjustment plate 2302. When the second screw rod 2304 is rotated, its end part will come into contact with the rocker arm 2303.

[0032] like Figure 5-6As shown, the correction assembly 30 includes a fixed convex ring 31, which is fixed on two reinforcing channel steels 12 near the center of the workbench 10 through bolts. A correction wheel frame 32 is movably set at the top center of the fixed convex ring 31, and a recess is set on the correction wheel frame 32.

[0033] Specifically, the working principle of the scaffolding steel pipe straightening device that adapts to different apertures is as follows: when in use, the steel pipe to be straightened is placed between the two clamping roller assemblies 20 in turn, and the handwheel 2205 and the second screw 2304 on the two clamping roller assemblies 20 are adjusted in turn, so that the upper clamping roller 2203 and the lower clamping roller 2201 clamp the steel pipe in the vertical direction, and the two side clamping rollers 2305 clamp the steel pipe in the horizontal direction. After the drive motor 40 is started, the steel pipe is moved by the rotation of a group of horizontal clamping rollers 22. At the same time, the construction personnel control the direction of the steel pipe so that when the bent part of the steel pipe runs to the correction assembly 30, it is close to the concave wheel 33 to increase the straightening effect. The steel pipe is straightened by the clamping and moving action of the two groups of clamping roller assemblies 20. Through the above structure, the problem that the existing technology can only adapt to the straightening of steel pipes of a single diameter and cannot cope with the straightening of steel pipes of different diameters is solved.

[0034] 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.
