TECHNICAL FIELD

[0001] The present application relates to the technical field of pipeline transportation, and in particular to a novel pipeline inner wall supporting device. BACKGROUND

[0002] Large metal circular pipelines are large water conveying structures in the fields of water conservancy, municipal administration and industry, and the diameters of the pipelines are often more than one meter. The circular cross section of the pipelines can uniformly convert stress into circumferential tension when bearing internal pressure, and the pipelines exhibit excellent buckling resistance when resisting external pressure, and the material utilization efficiency is high. Such pipelines are key parts of water diversion and regulation, urban drainage and industrial water conveying systems, and the reliability thereof depends on reasonable selection, effective corrosion prevention and standardized construction.

[0003] However, in the prior art, after the metal pipeline is produced, it needs to be distributed and transported to the construction site. During the transportation process, the cylindrical pipeline may be deformed (easily become elliptical) due to the external force. Therefore, after arriving at the construction site, the pipeline cannot be used normally and constructed. At the present stage, in order to avoid this problem, a metal rod is welded on the inside of the pipeline to avoid deformation caused by external force. However, when welding inside the pipeline, it is necessary to ensure that the two ends of the metal rod are in close contact with the inner wall, and then welding is performed. The construction difficulty is high, and when transported to the construction site, the welded metal rod also needs to be removed, resulting in a very complicated work process. Therefore, the present application provides a novel pipeline inner wall supporting device to solve the technical problems in the background art. SUMMARY

[0004] In view of the deficiencies in the prior art, the purpose of the present application is to provide a novel pipeline inner wall supporting device to solve the technical problems in the background art.

[0005] The above purpose of the present application is achieved by the following technical solution: a novel pipeline inner wall supporting device, comprising a supporting assembly arranged inside a metal pipeline, the supporting assembly comprising a rectangular mounting frame and a mounting bottom plate fixedly connected to the rectangular mounting frame, a plurality of supporting rods being mounted on the mounting bottom plate, a guide rod being fixedly arranged on one end of the supporting rod close to the mounting bottom plate, a guide assembly being arranged on the mounting bottom plate for limiting linear movement of the guide rod, and an adjusting assembly being arranged on the mounting bottom plate for driving movement of the plurality of guide rods.

[0006] By adopting the above technical solution, when the metal pipeline needs to be transported, the supporting assembly is placed inside the metal pipeline, the outer sides of the plurality of supporting rods are supported on the inner side of the metal pipeline, and then the plurality of guide rods are adjusted by the adjusting assembly to move outwardly of the metal pipeline, so that the supporting rods are completely in close contact with the inner side of the metal pipeline, achieving the purpose of temporary support.

[0011] Further, a groove is formed in the end of the guide rod close to the slope of the adjusting wedge, a pulley rotatingly connected to the guide rod is arranged in the groove, and the pulley abuts against the outer side of the adjusting wedge when the adjusting wedge is adjusted.

[0012] By adopting the above technical scheme, in order to avoid the friction between the adjusting wedge and the guide rod, which causes damage to the two, the pulley arranged on the guide rod in the application can greatly reduce the friction between the two when the adjusting wedge is driven, thereby increasing the service life.

[0013] Further, the driving assembly comprises a guide frame fixedly connected to the mounting base plate, a driving screw is rotatingly arranged on the guide frame, a threaded sleeve is threadedly arranged on the driving screw, a circular hole is formed in the inner side of the adjusting wedge, the threaded sleeve is arranged in the circular hole, a lead screw is outwardly extended from the driving screw, a support is fixedly arranged on the guide frame, and the lead screw is rotatingly connected to the support.

[0017] Further, a support seat is rotatably arranged on the hinge seat, and an arc surface is formed on the outer side of the support seat.

[0018] By adopting the above technical scheme, the support seat is rotatably arranged on the hinge seat, which can better fit the inner side of the metal pipeline after the hinge seat is adjusted, and since the inner side of the metal pipeline is also an arc surface, the outer side of the support seat is also arranged as an arc surface, so that the two can better fit.

[0019] Further, a hard rubber is fixedly arranged on the arc surface of the support seat.

[0020] In summary, the application has the following beneficial technical effects: firstly, the support protection layer performs well, when the metal pipeline is transported, the outer sides of the multiple support rods are closely fitted to the inner side of the pipeline, which can effectively resist the gravity of the pipeline itself, the bumps during transportation and external force collision, prevent the pipeline from being deformed, concave or damaged, and ensure the integrity and stability of the pipeline during transportation; the adjustment assembly design makes the device have strong adaptability, can be flexibly adjusted according to metal pipelines of different diameters, and through the adjustment of the guide rod to drive the support rod to fit the pipeline, the support demand of pipelines of various specifications is met, and the use range is expanded.

In terms of operation and use, the adjustment assembly cooperates with the driving assembly through the adjusting wedge, the driving screw is driven to rotate by the external adjusting screw, and then the threaded sleeve drives the adjusting wedge to move forward and backward to push the guide rod and the support rod, which is simple and easy to understand, does not require complex procedures and professional skills, and the staff can quickly get started, improving the installation and adjustment efficiency.

[0022] The pulley arranged on the guide rod is in contact with the adjusting wedge inclined surface during adjustment, which greatly reduces the friction therebetween, reduces wear during adjustment, prolongs the service life of the device, and reduces the cost of repairing and replacing parts.
