[0001] The utility model relates to the technical field of building construction, in particular to a pipeline prefabricated rolling bracket. Background Art

[0002] At present, a large amount of pipeline prefabrication work needs to be carried out in the construction of electromechanical installation projects. In the conventional pipeline prefabrication process, a simple auxiliary bracket is directly used. The existing simple auxiliary bracket adopts a triangular fixed bracket, which is welded by two thick steel plates and four round tubes. The upper part presents an inverted triangle to place the pipeline, and the four round tubes below serve as legs. When the pipeline is prefabricated, it is placed on the triangular fixed bracket for welding. The disadvantage of this method is that the pipeline needs to be rotated during prefabrication. The traditional auxiliary bracket has large friction resistance, and coupled with its own gravity, it makes it particularly difficult to rotate the pipe. For some large-diameter pipes, this bracket is no longer applicable, and prefabrication requires welders to squat on the ground to weld the pipe. This welding method is extremely inconvenient to operate, which has a certain impact on the welding quality. The repair and expansion of the weld will waste manpower, time and economic costs.

[0003] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art already known to a person skilled in the art.

[0009] The inner ring of the bearing is sleeved on the outside of the support rod, and at least two bearings are arranged on the support rod. The outer ring of the bearing is supported on the outside of the pipe to be processed.

[0010] Furthermore, the plurality of through holes are arranged at equal intervals along the width direction of the support platform.

[0023] The support platform 1 is rectangular. A plurality of legs are provided at the bottom of the support platform 1. In this embodiment, the number of legs is four. The four legs are respectively provided at the four corners of the support platform.

[0024] A plurality of through holes are respectively formed at opposite ends of the support platform 1. The plurality of through holes are spaced apart along the width direction of the support platform 1.

[0025] As a preferred embodiment, a plurality of through holes are arranged at equal intervals along the width direction of the support platform 1 .

[0026] The number of the support rods 2 is two. The two support rods 2 are arranged in the same direction. The support rods 2 are arranged above the support platform 1. The support rods are arranged along the length direction of the support platform 1. Vertical rods are formed at both ends of the support rods 2. The lower ends of the vertical rods are detachably inserted into the through holes.

[0027] In this embodiment, each vertical rod is equipped with two locking members 4. The locking members 4 are provided with threaded holes. The vertical rod is formed with external threads. The lower end of the vertical rod is screwed with two locking members 4. The two locking members 4 are pressed against the top and bottom of the support platform 1 respectively.

[0028] The bearing 3 is a roller bearing. The inner ring 31 of the bearing 3 is sleeved on the outside of the support rod 2. At least two bearings 3 are arranged on the support rod 2. The outer ring 32 of the bearing 3 is supported on the outside of the pipe 7 to be processed.

[0029] As a preferred embodiment, the positions of the bearings 3 on the two support rods 2 correspond one to one.

[0030] The pipeline prefabricated rolling support of the utility model also includes a centrifugal piece 5. In this embodiment, the inner ring of the bearing is rotatably sleeved on the support rod. The centrifugal piece 5 is arc-shaped. The centrifugal piece 5 has a first end and a second end in the arc direction. The centrifugal piece 5 is arranged between the inner ring 31 and the outer ring 32. The inner arc surface of the centrifugal piece 5 is arranged toward the inner ring 31. The first end of the centrifugal piece 5 is hinged to the outer side surface of the inner ring 31. A reset spring 6 is connected between the second end of the centrifugal piece 5 and the inner ring 31. A friction plate 8 is provided on the outer arc surface of the centrifugal piece 5. After the inner ring 31 rotates and the centrifugal force on the second end of the centrifugal piece 5 is greater than the elastic force of the reset spring 6, the friction plate 8 on the centrifugal piece 5 is pressed against the inner side surface of the outer ring to reduce the rotation speed of the inner ring 31.

[0031] In this embodiment, four 10# channel steels are installed at the bottom of the base as supporting legs, and the spacing and verticality of the supporting legs are adjusted.

[0032] The pedestal is welded to the supporting legs, and holes are drilled on the pedestal to control the distance between the two symmetrical holes on the pedestal to range from 50cm to 250cm.

[0033] The locking piece is screwed into the vertical rod to facilitate the adjustment of the height of the support rod. After the production is completed, the vertical rod of the support rod equipped with the bearing is directly inserted into the perforation of the base and fixed with the locking piece.

[0037] The utility model discloses a pipeline prefabricated rolling support, wherein the friction plate is fixed on the centrifugal plate. When the speed of the inner ring reaches a limited value, the centrifugal force is greater than the pull of the return spring, the centrifugal plate is thrown out, and the friction plate fixed on the centrifugal plate contacts the outer ring to generate friction to reduce the speed of the inner ring. The outer ring is formed with a keyway for limiting the axial position of the bearing, thereby increasing the stability of the bearing fixation.

[0038] The utility model of pipeline prefabrication rolling bracket reduces the number of fixed ports in welding during pipeline prefabrication, making it easier for welders to operate, reducing labor intensity and improving welding efficiency and qualification rate. So far, it has reduced steel consumption by 2 tons, saved processing time by 35 days, and saved costs by about 70,000 yuan.

[0039] The utility model of the pipeline prefabrication rolling bracket has a simple structure, is easy to produce, easy to operate, and can effectively save labor. By drilling holes of different spacings on the support platform, the spacing of the support rods can be adjusted to meet the prefabrication of pipelines of various calibers; the bearing rotates to drive the pipeline to rotate, and the welding prefabrication of pipelines at various angles is realized, which is convenient, fast and efficient.
