Description

Technical Field

[0001] The invention relates to a water pressure test tool, in particular to a tube panel module hydraulic water pressure test platform, belonging to the technical field of boiler equipment. Background Art

[0002] The water pressure test is a necessary process after the pipe panel is manufactured. The operation of the water pressure test of the pipe panel is usually to lift the pipe panel and place it on the platform used for the water pressure test. After the pipe panel is placed in place, the pipe joints are sealed and water is poured in. Then the pressure is increased to the specified pressure by the hydraulic press to test the pressure resistance and sealing performance of the pipe panel. After the water pressure test is completed, the water is drained and the pipe panel is lifted off the platform after the water is drained. During the drainage process, in order to reduce the drainage time and ensure that the water is drained, one end of the pipe panel is usually lifted with a crane to complete an operation similar to pouring water.

[0003] The existing water pressure test platform and operation still have the following defects: since the amount of water stored in the tube panel is large and the drainage time is long, the drainage of the tube panel needs to occupy the crane for a long time, which affects the efficiency of the crane; for the water pressure test of large tube panel modules, since the weight of the tube panel module plus the weight of water will increase exponentially compared with a single tube panel, and may even exceed the lifting capacity of the crane, it is difficult to lift one end of the tube panel module to complete the water pouring operation.

[0005] The present invention solves the above technical problems mainly through the following technical solutions: the present invention includes a base, a platform horizontally arranged on the base for placing the tube panel module, and a hydraulic jacking mechanism arranged on the base. The rear end of the platform is hinged to the base and the front end can be lifted by the hydraulic jacking mechanism.

[0006] Preferably, the hydraulic jacking mechanism includes a hydraulic jack and a control box, the bottom end of the hydraulic jack is fixed to the base and the top end is hinged to the platform, and the control box is installed on the side of the base.

[0007] Preferably, it also includes a linking device installed between the base and the platform, and the linking device is used to connect the base and the platform.

[0008] Preferably, a positioning block is provided at the rear end of the platform to prevent the tube panel module from sliding out of the platform.

[0009] Preferably, there are two hydraulic jacks, and the top ends of the hydraulic jacks are hinged to the front middle part of the platform.

[0011] A space for accommodating a linking device and a hydraulic push rod is arranged inside the base. When the hydraulic push rod and the linking device are in a retracted state, they are accommodated in the internal space of the base.

[0012] The present invention has a simple structure, reasonable design, and has the following advantages: The present invention is provided with a base for placing the platform, a hydraulic jacking mechanism is placed in the base, and the rear end of the platform is hinged to the base. When the pipe panel module placed on the platform needs to be drained, the front end of the platform is lifted up by the hydraulic jacking mechanism, so that the water in the pipe panel module can be discharged at the low position of the rear end of the platform, and the water pouring operation of the pipe panel module is completed. The hydraulic jacking mechanism has the advantages of large lifting force and stable lifting, and can meet the needs of completing rapid drainage through pouring operation during the water pressure test of large and super-large pipe panel modules.

[0013] Furthermore, the bottom end of the hydraulic jack is fixed to the base and the top end is hinged to the platform, and the platform can be flipped when the hydraulic jack is extended or retracted; the control box is arranged on the side of the base, which can facilitate the operator to control the lifting and lowering of the hydraulic jack.

[0014] Furthermore, a linking device is provided between the base and the platform, and the connection between the platform and the base is achieved through the linking device.

[0015] Furthermore, a positioning block is provided at the rear end of the platform, which can block the tube panel module when the platform is flipped over to prevent the tube panel module from sliding out of the platform.

[0016] Furthermore, the lifting and flipping structure with a central double rod has the advantages of short lifting stroke and stable lifting.

[0017] Therefore, the present invention solves the technical problems in the prior art that the pipe panel module occupies the overhead crane when draining water and the water pouring operation of the pipe panel module is limited. It has the advantages of simple structure, convenient operation, and strong lifting force, and can complete the water pouring operation during the water pressure test of large and super-large pipe panel modules.
