[0002] Pressure piping refers to tubular equipment that uses a certain pressure to transport gas or liquid. The pressure pipeline is a part of the pipeline. The pipeline is used to transport, distribute, mix, separate, discharge, measure, control and stop the flow of fluids. It is an assembly consisting of pipes, fittings, flanges, bolted connections, gaskets, valves, other components or pressure-bearing parts and supports.

[0003] During the transportation process of the pressure pipeline, the pressure pipeline will be inspected by a camera, and then the pressure pipeline will be inspected. The camera is usually fixedly installed on one side of the pressure pipeline, and the pressure pipeline is inspected by the camera. However, this detection method has the following shortcomings when used: due to the large specifications of the pressure pipeline, evenly distributed support seats will be set at the bottom of the pressure pipeline, which requires a camera to be installed next to each section of the pressure pipeline, thereby increasing the operating cost; and the fixed installation of the camera results in a limited detection line of sight of the camera, which makes it difficult for the detection camera to fully detect the pressure pipeline, thereby affecting the detection of the pressure pipeline. Utility Model Content

[0004] The utility model aims to solve the problem in the prior art that it is difficult to fully inspect the pressure pipeline due to the fixed installation of the inspection camera, and proposes a supporting device that is convenient for the inspection of the pressure pipeline.

The detection camera is arranged at the connection end, and a drive component for driving the rack is installed in the support.

[0007] Preferably, the connecting member includes a motor 1 fixedly installed in the bracket, and a screw rod is fixedly connected to the output end of the motor 1, a matching nut is slidably sleeved on the screw rod, and the sleeve is arranged on the nut.

[0021] A matching electric guide rail 2 and a slider 3 are provided on one side of the pressure pipe, and a bracket 4 is fixedly installed on the slider 3. By providing an electrically connected electric guide rail 2 and a slider 3 on one side of the pressure pipe, the slider 3 can drive the detection camera 1 to move when moving, thereby being able to detect a pressure pipe of a larger specification;

[0022] The bracket 4 is connected to a sleeve 8 through a connecting piece, and the connecting piece includes a motor 5 fixedly installed in the bracket 4, and a screw rod 6 is fixedly connected to the output end of the motor 5, and a matching nut 7 is slidably sleeved on the screw rod 6, and the sleeve 8 is arranged on the nut 7. The screw rod 6 is arranged horizontally, and a limiting long hole 9 for guiding the sleeve 8 is provided on the bracket 4. The limiting long hole 9 guides the sleeve 8, thereby limiting the moving direction of the nut 7;

[0023] The motor 5 drives the screw rod 6 to rotate and drive the nut 7 to move horizontally. The nut 7 can drive the guide frame 12 and the detection camera 1 to move closer to or away from the pressure pipe when moving. When the guide frame 12 and the detection camera 1 are away from the pressure pipe, they can be away from the support seat at the bottom of the pressure pipe, thereby ensuring the smooth movement of the detection camera 1.

[0024] An extension rod 10 is placed in the sleeve 8, and a support 11 is fixedly installed on the extension rod 10. The support 11 and the extension rod 10 extend to the upper end position outside the sleeve 8, and a locking bolt corresponding to the extension rod 10 is threadedly connected on the sleeve 8. By lifting or pressing the extension rod 10, the extension rod 10 drives the support 11, the guide frame 12, and the detection camera 1 to rise and fall, thereby adjusting the height of the detection camera 1;

[0025] A guide frame 12 is fixedly mounted on the support 11, a rack 14 is provided in a sliding sleeve inside the guide frame 12, and three circumferentially distributed connection ends 15 are fixedly mounted on the rack 14, and the detection camera 1 is arranged at the connection end 15;

[0026] The guide frame 12 is a semi-annular structure, the rack 14 is an incomplete annular structure, the detection camera 1 and the connecting end 15 extend to one side outside the guide frame 12, and a guide long hole 16 for guiding the connecting end 15 is provided on the guide frame 12, and the two ends of the rack 14 are integrally connected with a limiting plate, the guide frame 12 guides the rack 14, and the guide long hole 16 guides the connecting end 15, so that the rack 14 can smoothly pull the connecting end 15 and the detection camera 1 when moving, and the limiting plate can limit the moving direction of the rack 14;

[0027] A driving assembly for driving the rack 14 is installed in the support 11;

[0028] The driving assembly includes a second motor 13 fixedly mounted on the support 11, and the output end of the second motor 13 is fixedly connected to a rotating shaft 17 that is transmission-connected to the rack 14, the rotating shaft 17 is horizontally arranged, and a gear 18 that is meshingly connected to the rack 14 is fixedly mounted on the rotating shaft 17;

[0029] The output end of the second motor 13 drives the rotating shaft 17 to rotate, and the rotating shaft 17 drives the gear 18 to pull the meshing rack 14. When the rack 14 slides in the guide frame 12, it drives the connecting end 15 and the detection camera 1 to rotate with the pressure pipe as the center point, thereby performing a comprehensive inspection of the pressure pipe;

[0030] It should be noted that the specific models and specifications of the detection camera 1, electric guide rail 2, motor 1 5, and motor 2 13 need to be selected and determined based on the actual specifications of the device, and the specific selection calculation method adopts the existing technology in the field, so it is not repeated here.

[0031] The functional principle of the utility model can be explained through the following operation modes:

[0032] When it is necessary to inspect the pressure pipeline;

[0033] The extension rod 10 is pulled so that the extension rod 10 drives the extension rod 10 to slide in the sleeve 8, and the sleeve 8 and the extension rod 10 are connected by a locking bolt, and the support 11 drives the guide frame 12 to correspond to the pressure pipe;

[0034] The electric guide rail 2 drives the slider 3 to move to one side of the pressure pipe;

[0035] The output end of the motor 5 drives the screw 6 to rotate, the screw 6 drives the nut 7 to slide to the right, the nut 7 drives the sleeve 8 to slide in the limit long hole 9, and the sleeve 8 drives the extension rod 10, the support 11, the guide frame 12, and the detection camera 1 to approach the pressure pipe when moving;

[0036] When the guide frame 12 is able to surround one side of the pressure pipe;

[0037] The motor 1 5 stops running, the output end of the motor 2 13 drives the shaft 17 to rotate, the shaft 17 drives the gear 18 to pull the meshing rack 14, the rack 14 drives the connecting end 15 to slide in the guide slot 16 when moving, and the connecting end 15 drives the detection camera 1 to rotate and detect the pressure pipeline;

[0038] After a section of the pressure pipe is inspected, the output end of the motor 2 13 drives the rotating shaft 17 to rotate in the opposite direction, returning the inspection camera 1 to the initial position, and then the output end of the motor 1 5 drives the screw rod 6 to rotate in the opposite direction, so that the guide frame 12 is away from the pressure pipe, and the guide frame 12 continues to move through the cooperation between the electric guide rail 2 and the slider 3.
