[0002] In construction, whether in hydropower plant buildings, industrial plants, or residential buildings, we need to classify and arrange complex equipment lines or electrical routes. Among them, electrical cables usually need to be protected by cable sheaths made of thin-walled steel pipes. Therefore, cable sheaths with different degrees of curvature need to be prepared before laying electrical cables.

[0003] During the installation of various cable sheaths, different building structures require cable sheaths with different degrees of bending, especially for exposed cable sheaths, which require a large number of cable sheaths with different degrees of bending, resulting in a large workload of on-site bending of the cable sheaths.

[0004] At present, construction units often use traditional hydraulic pipe bending machines for bending, which has low work efficiency, so there is an urgent need for a thin-walled steel pipe bending device to quickly bend the cable casing. Utility Model Content

The carrier plate is fixedly installed on the ground through the support frame, and the bending wheel is rotatably installed on the carrier plate. The guide small pulley assembly for bending the thin-walled steel pipe is rotatably installed on the bending wheel through the bogie, so that the small pulley assembly can rotate around the bending wheel, and the rotation center of the guide small pulley assembly coincides with the rotation center of the bending wheel. The carrier plate is also equipped with a fixed block for limiting the movement of the thin-walled steel pipe and a limit block for determining the bending angle of the thin-walled steel pipe.

[0007] Optionally, in some embodiments, the bending wheel is located in the middle of the carrier plate, the fixed block is fixedly connected to one side of the carrier plate, and a plurality of limit block holes are correspondingly provided on the other side of the carrier plate. By inserting the limit blocks into different limit block holes, the bending angle of the thin-walled steel pipe can be limited.

[0008] Optionally, in some embodiments, the bogie is U-shaped, and the end of the bogie is rotatably mounted at the center position of the bending wheel, and a guide pulley assembly corresponding to the bending wheel is also rotatably mounted on the bogie.

[0028] See also Figure 1 The thin-walled steel pipe bending device includes a carrier plate 1, a bending wheel 2, a bogie 3, a guide pulley assembly 4, a handle 5, a limit block 7, a fixed block 6, and a support frame 8. The carrier plate 1 is fixedly installed on the ground through the support frame 8, and the carrier plate 1 is rotatably installed with the bending wheel 2. The guide pulley assembly 4 for bending the thin-walled steel pipe 9 is rotatably installed on the bending wheel 2 through the bogie 3, and the rotation center of the guide pulley assembly 4 coincides with the rotation center of the bending wheel 2. At the same time, the carrier plate 1 is also equipped with a fixed block 6 for limiting the movement of the thin-walled steel pipe 9 and a limit block 7 for determining the bending angle of the thin-walled steel pipe 9. In addition, for different force requirements, different handle 5 lengths can be set, or auxiliary force rods can be added to meet the use requirements. It should be noted that the bending wheel 2 is located in the middle of the carrier plate 1, and the fixed block 6 is fixedly connected to one side of the carrier plate 1. A plurality of limit block holes are correspondingly provided on the other side of the carrier plate 1. By inserting the limit blocks into different limit block holes, the bending angle of the thin-walled steel pipe can be limited. Specifically, for a batch of thin-walled steel pipes with the same bending angle, angle marking lines and limit block holes are provided on the carrier plate 1 with the fixed block 6 as the starting point. The position of the limit block can be flexibly adjusted according to the required bending angle to ensure that the bending angle of the thin-walled steel pipe 9 is the required bending angle, so that the device improves the bending efficiency and is easy to operate.

[0029] See also Figure 2 and Figure 3 In this embodiment, the guide pulley assembly 4 includes a guide pulley 41, a connecting plate 42, and a pin 43, and the guide pulley assembly 4 is rotatably installed on the bogie 3, wherein the two connecting plates 42 are aligned up and down and the two guide pulleys 41 are symmetrically arranged between the two plates, so that the connecting plate 42 and the guide pulley 41 form a guide assembly, and the formed guide assembly can rotate around the pin 43, so that when the thin-walled steel pipe 9 is bent with the rotation of the bending wheel 2, the guide assembly can fit the pipe wall, ensuring that the thin-walled steel pipe 9 will not deviate during the bending process, so that the deviation angle is more accurate.

[0030] In addition, in this embodiment, corresponding semicircular grooves are provided on the bending wheel 2 and the guide pulley 41, and the diameter of the groove should be slightly larger than the outer diameter of the thin-walled steel pipe 9, so as to ensure that the thin-walled steel pipe 9 can be confined between the bending wheel 2 and the guide pulley assembly 4, so that the bent pipe is well formed and not prone to axial deviation.

[0031] In addition, in this embodiment, the support frame 8 includes a mounting bracket 81 and a base 82, and the base 82 is provided with bolt holes. During installation, expansion bolts can be used to fix the base 82 to the ground to improve the stability of the entire device.

[0032] It should also be noted that, in this embodiment, the bogie 3 is welded from 14 mm thick steel plates, and the mounting bracket 81 is welded from 8# channel steel, which can ensure the stability of the device.

[0033] In particular, the thin-walled steel pipe bending device of the utility model can not only bend thin-walled galvanized steel pipes, but also bend pipe fittings made of other materials such as aluminum and copper.

[0034] Specific working process:

[0035] When in use, the base 82 is fixed to the ground with expansion bolts, the limit block 7 is fixed to the corresponding limit block socket according to the required bending angle, the thin-walled steel pipe 9 is extended between the bending wheel 2 and the guide small pulley 41, and the bogie 3 is rotated clockwise so that one end of the thin-walled steel pipe 9 is connected to the fixed block 6, one end of the thin-walled steel pipe 9 is fixed, and then the handle 5 is continued to be rotated clockwise. At this time, the thin-walled steel pipe 9 is bent along the bending wheel 2, and the bending wheel 2 is the main force fulcrum, until the other end of the thin-walled steel pipe 9 is connected to the limit block 7. Finally, the thin-walled steel pipe between the large and small pulleys will be cold-bent to obtain a thin-walled steel pipe with the required bending angle.

[0036] Finally, it should be noted that, in this article, relationships such as first and second, etc. are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
