[0017] The pressure pipeline detection device provided in this disclosure can achieve the following technical effects:

[0018] This disclosure provides a pressure pipeline testing device, comprising a support frame, a first hydraulic cylinder, a clamping plate, a hollow block, a valve, a pressure gauge, a support block, a pressure block, and a driving component. The support frame includes a bottom plate and a top plate parallel to each other in their respective planes. Along the height direction of the support frame, the bottom plate is located below the top plate, and the bottom and top plates respectively support relevant components of the installation device. The first hydraulic cylinder is installed on the top surface of the bottom plate along the length direction of the support frame, providing driving force to achieve linear movement. The clamping plate is installed on the moving end of the first hydraulic cylinder and moves under the drive of the first hydraulic cylinder. The hollow block is installed on the top surface of the bottom plate, and includes a through hole communicating with its interior, the through hole being directly opposite the clamping plate. The valve is installed on the side wall of the hollow block and communicates with its interior, for connection to an air supply device. When the valve is in the open state, the air supply device can supply air to the interior of the hollow block. When the valve is in the closed state, it can block the air supply device from supplying air to the interior of the hollow block. A pressure gauge is installed on the side wall of the hollow block and is connected to the interior of the hollow block for detecting water pressure. A support block is installed on the top surface of the base plate and located between the clamping plate and the hollow block, used to support and limit the pressure pipe. A pressure block is located between the support block and the top plate, used to abut against the outer wall of the pressure pipe. A driving component is installed between the pressure block and the top plate, used to provide driving force to move the pressure block in the direction of the support block.

[0019] In operation, after the pressure pipe is placed on the support block, the first hydraulic cylinder is activated, causing the clamping plate to move. This clamps the pressure pipe between the hollow block and the clamping plate, at which point the through-hole connects to the interior of the pressure pipe. Then, opening the valve allows the air supply device to supply air into the hollow block, which then enters the pressure pipe through the through-hole. During the air supply process, a pressure gauge continuously monitors the pressure on the pipe, thus completing the internal pressure detection. Simultaneously, the drive mechanism moves the pressure block towards the support block until it presses against the outer wall of the pressure pipe, completing the external pressure detection. Therefore, both internal and external pressure of the pressure pipe can be detected simultaneously, improving detection efficiency.

[0036] Combination Figures 1 to 4As shown, this embodiment of the present disclosure provides a pressure pipeline testing device, including a support frame 10, a first hydraulic cylinder 20, a clamping plate 30, a hollow block 40, a valve 50, a pressure gauge 60, a support block 70, a pressure block 80, and a driving component 90. The support frame 10 includes a bottom plate 11 and a top plate 12 that are parallel to each other in their respective planes. Along the height direction of the support frame 10, the bottom plate 11 is located below the top plate 12. The bottom plate 11 and the top plate 12 are respectively used to support and install relevant components of the device. The first hydraulic cylinder 20 is installed on the top surface of the bottom plate 11 along the length direction of the support frame 10, and is used to provide driving force to achieve linear movement. The clamping plate 30 is installed on the moving end of the first hydraulic cylinder 20 and moves under the drive of the first hydraulic cylinder 20. The hollow block 40 is installed on the top surface of the bottom plate 11, and the hollow block 40 includes a through hole communicating with its interior, the through hole being directly opposite the clamping plate 30. Valve 50 is installed on the side wall of hollow block 40 and communicates with the interior of hollow block 40 for connection to air supply equipment. When valve 50 is open, air supply equipment can supply air to the interior of hollow block 40. When valve 50 is closed, it can block air supply equipment from supplying air to the interior of hollow block 40. Pressure gauge 60 is installed on the side wall of hollow block 40 and communicates with the interior of hollow block 40 for detecting water pressure. Support block 70 is installed on the top surface of base plate 11 and located between clamping plate 30 and hollow block 40 for supporting and limiting the pressure pipeline. Pressure block 80 is located between support block 70 and top plate 12 for abutting against the outer wall of pressure pipeline. Driving component 90 is installed between pressure block 80 and top plate 12 for providing driving force to drive pressure block 80 to move in the direction of support block 70.

[0037] This embodiment of the invention provides a pressure pipeline detection device. After the pressure pipeline is placed on the support block 70, the first hydraulic cylinder 20 is activated, which moves the clamping plate 30. The pressure pipeline is then clamped between the hollow block 40 and the clamping plate 30, with the through-hole connecting to the interior of the pressure pipeline. The valve 50 is then opened, allowing the air supply device to supply air to the interior of the hollow block 40, and water can enter the pressure pipeline through the through-hole. During the air supply process, the pressure gauge 60 continuously monitors the pressure on the pipeline, thus completing the internal pressure detection. Simultaneously, the drive component 90 is activated, moving the pressure block 80 towards the support block 70 until it abuts against the outer wall of the pressure pipeline and presses continuously, thus completing the external pressure detection. Therefore, both the internal and external pressures of the pressure pipeline can be detected simultaneously, improving detection efficiency.
