Description

Technical Field:

[0001] The utility model relates to the technical field of large-diameter pipeline cleaning, and particularly relates to a bracket for a pipeline cleaning nozzle. Background Art:

[0002] In the construction of large-diameter pipeline cleaning projects in large-scale oil refining and chemical plants, generally, the cleaning conditions of pipelines are relatively complex. Firstly, the pipeline diameter is large and the vertical height is high. Secondly, the internal corrosion, scaling and sediment thickness of the pipeline are large and the hardness is high, forming a ring arch effect that is not easy to fall off. Currently, in the high-pressure water jet cleaning process, the cleaning nozzle uses its own supporting fixed cage as a support and protection guiding component. The existing brackets rely on the angle tensioning and chute clamping structures to adjust the direction of the cleaning nozzle. If the inner diameter of the cleaning pipeline is small or the internal scaling is thick, resulting in a narrow movement range of the cleaning nozzle, the difficulty of adjustment will increase, and the chute clamping structure is prone to deformation in the wet environment of high-pressure water jet. Content of the Utility Model:

[0003] The technical problem to be solved by the utility model is to provide a bracket for a pipeline cleaning nozzle. The device can adjust the direction of the cleaning nozzle at multiple angles, has high support strength, is not easy to deform, has corrosion resistance, meets the requirements of the high-pressure water cleaning working environment, improves the stability of the cleaning nozzle, and greatly improves the high-pressure water jet cleaning operation efficiency and cleaning effect of large-diameter pipelines.

[0004] The technical solution adopted by the utility model is: a bracket for a pipeline cleaning nozzle, including a central pipe, and multiple groups of bracket mechanisms are sleeved on the central pipe;

[0005] The bracket mechanism includes a central sleeve sleeved on the central pipe. The central sleeve is circumferentially and equiangularly connected with a plurality of rod group angle adjustment mechanisms. The rod group angle adjustment mechanisms are connected with the rod group. The rod group can adjust the connection angle on the rod group angle adjustment mechanism, thereby adjusting the angle between the rod group and the axial direction of the central pipe. The length of the rod group can be adjusted, and a guide wheel is installed at the outer end of the rod group.

[0006] Further, the central sleeve is circumferentially and equiangularly connected with 3 rod group angle adjustment mechanisms.

[0007] Further, the rod group angle adjustment mechanism includes a sector-shaped fixing hole plate. The sector-shaped fixing hole plate is circumferentially and equiangularly designed with a plurality of bolt holes. The rod group is detachably fixedly connected by selecting bolt holes at different angles on the sector-shaped fixing hole plate, thereby adjusting the connection angle on the rod group angle adjustment mechanism.

[0008] Further, the rod group includes a porous fixing rod and a telescopic joint. The porous fixing rod is radially designed with a plurality of bolt holes. The telescopic joint is inserted into the porous fixing rod and is detachably fixedly connected with the bolt holes of the porous fixing rod.

[0009] Furthermore, an installation bracket is connected to the central pipe, and a camera and lighting equipment can be installed on the installation bracket.

[0010] Furthermore, the central sleeve is detachably and fixedly connected to the central pipe.

[0011] Furthermore, 2 - 3 sets of bracket mechanisms are sleeved on the central pipe.

A plurality of rod group angle adjustment mechanisms are circumferentially and equiangularly connected to the central sleeve 2. The rod group angle adjustment mechanism is connected to the rod group. The rod group can adjust the connection angle on the rod group angle adjustment mechanism, thereby adjusting the angle between the rod group and the axis of the central pipe 1. The length of the rod group can be adjusted, and a guide wheel 6 is installed at the outer end of the rod group.

[0024] Three rod group angle adjustment mechanisms are circumferentially and equiangularly connected to the central sleeve 2.

A plurality of bolt holes are designed circumferentially and equiangularly on the sector-shaped retaining hole plate 3. The rod group is bolted to different-angle bolt holes on the sector-shaped retaining hole plate 3, thereby adjusting the connection angle on the rod group angle adjustment mechanism.

The high-pressure water pipe of the high-pressure cleaning equipment penetrates from one end of the central pipe 1, and the high-pressure water cleaning nozzle connected to the front end of the high-pressure water pipe is connected to the outlet at the other end of the central pipe 1.

[0032] When it is necessary to adjust the direction of the high-pressure water cleaning nozzle, all groups of support mechanisms can be adjusted. The connection angle of the rod group on the rod group angle adjustment mechanism is adjusted, thereby adjusting the angle between the rod group and the axis of the central pipe 1. At the same time, the length of the rod group is adjusted in cooperation. Finally, the inclination angle of the central pipe 1 in the inner wall of the large-diameter pipeline is adjusted, thereby adjusting the direction of the high-pressure water cleaning nozzle and making the high-pressure water jet cleaning effect of the large-diameter pipeline better.

[0033] A camera and lighting equipment are equipped on the mounting bracket 7 of the central pipe 1 to facilitate real-time monitoring of the cleaning quality and control of the running speed of the spray head.
