The lifting anti-skid assembly comprises a holding ring A and a holding ring B which can be relatively opened or fastened outside the construction pipeline; and the holding ring B is provided with a supporting arm for supporting the infusion hose. The infusion hose is lifted by the support arm at the tail end of the tow bar, so that the infusion hose is prevented from sliding down due to gravity after high-pressure fluid is introduced, and the problem that the infusion hose slides down to the construction ground to be damaged due to gravity after high-pressure fluid is introduced is solved.

Description

Technical Field

[0001] The utility model relates to a pressurized and sealed testing structure for a construction pipeline, belonging to the technical field of pipeline testing. Background Art

[0002] During the construction and laying of pipelines used to transport chemical fluids, a single section of pipeline must be subjected to a pressurized leak test to detect any damage during production and transportation. This test involves sealing both ends of the pipeline and then injecting high-pressure fluid into the pipeline through a fluid delivery tube (see Chinese Patent Publication No. CN109357952A).

[0003] To facilitate storage of the infusion tube, the infusion tube is formed of a flexible tube. However, when the infusion tube is distributed outside the construction pipeline, the infusion tube will slide to the construction ground due to gravity after the high-pressure fluid is passed through it, causing damage. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a construction pipeline pressurized and sealed testing structure.

[0005] The utility model is achieved through the following technical solutions.

[0006] The utility model provides a construction pipeline pressurization and sealing test structure, comprising:

[0007] Construction pipelines;

[0008] A lifting and anti-skid component is installed on the construction pipeline to lift the infusion hose and prevent it from slipping.

[0009] Both ends of the construction pipeline are equipped with sealing plugs for blocking the openings at both ends of the construction pipeline.

[0010] The sealing plug is connected with a valve, which is connected with an infusion hose.

[0011] The lifting and anti-slip component includes a holding ring A and a holding ring B which can be relatively opened or fastened on the outside of the construction pipeline; the holding ring B is provided with a supporting arm for lifting the infusion hose.

[0012] The holding ring B is provided with an articulated seat, which is provided with a square articulated groove. A tow bar is mounted on the articulated seat so as to be able to rotate forward and backward. The tow bar is a square body and can only be rotated forward and backward after being matched with the square articulated groove.

[0013] The end of the tow rod away from the construction pipeline is integrally fixedly connected with a supporting arm for lifting the infusion hose;

[0014] The end of the drag rod close to the construction pipeline is fixed in the hinge groove of the hinge seat through an elastically deformable elastic rubber body. When the drag rod swings back and forth, the elastic rubber body provides elastic damping to prevent random rotation and swing.

[0015] One end of the holding ring A and one end of the holding ring B can be relatively rotatably hinged, and one end of the holding ring A and one end of the holding ring B are detachably tightened and fixedly connected by bolts and nuts.

[0016] The beneficial effect of the utility model is that the support arm at the end of the tow rod lifts the infusion hose to prevent the infusion hose from sliding down due to gravity after the high-pressure fluid is introduced, thereby solving the problem that the infusion hose may slide down to the construction ground and be damaged due to gravity after the high-pressure fluid is introduced.

[0020] The technical solution of the present invention is further described below, but the scope of protection claimed is not limited to the described solution.

[0021] like Figures 1 to 2 shown.

[0022] A construction pipeline pressurized and sealed testing structure of the present application comprises:

[0023] The construction pipeline 1 is in a single-segment state and needs to undergo a pressurized airtightness test. Sealing plugs 2 are fixedly installed at both ends of the construction pipeline 1 to seal and block the openings at both ends of the construction pipeline 1 .

[0024] The sealing plug 2 is connected to a valve 3 , which is connected to a liquid infusion hose 4 , and high-pressure fluid is input into the construction pipeline 1 through the liquid infusion hose 4 and the valve 3 .

[0025] The construction pipeline 1 is installed with a lifting and anti-skid component for lifting the infusion hose 4 to prevent it from slipping.

[0026] The lifting and anti-slip assembly includes a ring A51 and a ring B52 that can be opened or fastened relative to the outside of the construction pipe 1. One end of the ring A51 and one end of the ring B52 can be relatively rotatably hinged. One end of the ring A51 and one end of the ring B52 are detachably and securely connected by a bolt 53 and a nut 54.

[0027] Ring B52 is provided with an articulated seat 55, which has a square articulated groove. A drag rod 56 is mounted on the articulated seat 55, which can only rotate forward and backward. The drag rod 56 is a square body that, when mated with the square articulated groove, can only rotate forward and backward. The end of the drag rod 56, which is away from the construction pipeline 1, is integrally connected to a supporting arm 57 that supports the infusion hose 4. The end of the drag rod 56, which is closer to the construction pipeline 1, is fixed in the articulated groove of the articulated seat 55 by an elastically deformable elastic rubber body 58. When the drag rod 56 swings back and forth, the elastic rubber body 58 provides elastic damping to prevent it from rotating and swinging randomly. The supporting arm 57 at the end of the drag rod 56 supports the infusion hose 4, preventing it from sliding down due to gravity after the high-pressure fluid is introduced. This solves the problem of the infusion hose sliding down to the construction site and causing damage due to gravity after the high-pressure fluid is introduced. The infusion prevention hose 4 held by the lifting anti-skid assembly does not slide down, thereby preventing the infusion prevention hose 4 from sliding down and causing deformation at the valve 3 to affect fluid input.
