Description

Technical Field

[0001] The present invention relates to the technical field of aluminum-plastic pipe repair, and in particular to a hot pressing and joining device for aluminum-plastic pipes. Background Art

[0002] The structure of aluminum-plastic pipes is already very common. When the pipeline is leaked after being impacted by external blunt force or punctured by sharp force, it is necessary to stop the transmission of the internal medium of the pipeline, cut the damaged part, then sleeve the intact large-diameter pipe section at both ends of the pipe to be repaired and seal it through a sealing structure. Since the aluminum pipe is embedded, the operation during cutting and repair is relatively complicated, and it is necessary to interrupt the medium transmission for a long time, with a slow recovery speed, and there is a great risk that debris and external pollutants will invade the interior of the pipeline at the cut pipe orifice. Summary of the Invention

[0003] The technical problem to be solved by the present invention is: in order to overcome the problems existing above, a hot pressing and joining device for aluminum-plastic pipes is provided, which solves the above problems.

[0004] The present invention solves its technical problems by adopting the following technical solutions:

[0005] A hot pressing and joining device for aluminum-plastic pipes includes a fixed half-clamp body, a movable half-clamp body, a pull frame, a clamping body, a ceramic seat, an electric heat conducting bar, and a hot pressing and joining half-pipe. Ear plates are fixedly welded on both sides of the fixed half-clamp body and the movable half-clamp body. The front end of the pull frame is hooked outside the ear plate on the fixed half-clamp body. A threaded cylinder is fixedly provided on the outside of the pull frame, a screw rod is threadedly connected in the threaded cylinder, and a grip cross bar is fixedly provided at the outer end of the screw rod. The front end of the screw rod passes through the pull frame and a pressure plate is fixedly provided at its front end. By pressing the pressure plate against the movable half-clamp body, the movable half-clamp body and the fixed half-clamp body are clamped together. The power source of the pressure plate is realized through the screw pair cooperation of the screw rod and the threaded cylinder, and the grip cross bar is used to apply force when rotating the screw rod. Ceramic seats are fixedly bolted on the inner walls of the fixed half-clamp body and the movable half-clamp body, and the electric heat conducting bar is fixed at the front end of the ceramic seat. The electric heat conducting bar is externally connected with a wire for power supply. The two hot pressing and joining half-pipes are oppositely sleeved on the crack opening of the pipeline to be repaired. The clamping body is fixed on the inner walls of the fixed half-clamp body and the movable half-clamp body and is located on both sides of the electric heat conducting bar. The front end of the clamping body contacts and clamps the hot pressing and joining half-pipe before the electric heat conducting bar during operation. Under the screw pair cooperation of the screw rod and the threaded cylinder, the pressure plate is pressed down until the electric heat conducting bar abuts between the opening seams of the two hot pressing and joining half-pipes.

[0006] Preferably, guiding slide bars are fixedly arranged at intervals on the ear plates on both sides of the fixed half clamp body, and guiding holes are fixedly arranged at intervals on the ear plates on both sides of the movable half clamp body. The guiding holes are for the guiding slide bars to pass through to guide the sliding track of the movable half clamp body.

[0007] Preferably, guiding slide bars are fixedly arranged at intervals on the ear plates on both sides of the fixed half clamp body, and guiding holes are fixedly arranged at intervals on the ear plates on both sides of the movable half clamp body. A sliding sleeve made of ceramic material or stainless steel material is fixedly installed in the guiding holes, the guiding slide bars are made of ceramic or stainless steel material and the guiding slide bars can be slidably inserted into the sliding sleeves fixedly installed in the guiding holes.

[0008] Preferably, after the guiding slide bars are inserted into the guiding holes, they are in clearance fit with the guiding holes.

[0009] Preferably, rubber sealing rings are symmetrically and fixedly arranged at both ends of the inner wall of the hot press bonding half pipe, and the inner curved wall of the hot press bonding half pipe is attached to the pipeline to be repaired.

[0010] Preferably, rubber sealing rings are fixedly arranged at equal intervals along the axis direction of the hot press bonding half pipe on the inner wall of the hot press bonding half pipe. The left and right end faces of the rubber sealing rings are flush with the left and right end faces of the hot press bonding half pipe. After the split rubber sealing rings are pressed on the outside of the pipeline to be repaired, an annular sealing ring is formed to divide the long strip-shaped crack into multiple pressure segments and the rubber sealing rings form a seal, which is convenient for quickly forming a seal.

[0011] Preferably, a flush flange strip and a flush groove are respectively fixedly arranged on the side plane ends of the hot press bonding half pipe. The flush flange strip can be fitted into the opposite flush groove. Under the clamping of the clamping body, the two split hot press bonding half pipes are clamped on the outside of the pipeline to be repaired to form a good external supporting force and at the same time, a seal is achieved through the inner rubber sealing rings.

[0012] Preferably, the clamping body includes a compensation spring unit and a rubber head. One end of the compensation spring unit is fixed to the inner wall of the fixed half clamp body by bolts, the rubber head is sleeved and fixed at the other end of the compensation spring unit, and the front end of the rubber head presses against the outside of the hot press bonding half pipe. After the fixed half clamp body and the movable half clamp body approach, the compensation spring unit contracts and deforms to push the contracted rubber head to clamp the hot press bonding half pipe.

[0013] Preferably, the side end face of the hot press bonding half pipe is wavy and the wavy wall surfaces of two adjacent split hot press bonding half pipes match each other.

[0014] The advantages and positive effects of the present invention are as follows: Compared with the existing repair processes and equipment, in this application, a semi-open tube made of aluminum-clamping material is sleeved outside the damaged body, and the opening seam of the hot-pressed joint semi-tube is melted by an electric heating strip device to complete the repair. In this way, compared with the prior art, the sealing of the damaged opening can be restored faster, and there is no need to cut the pipeline, and the risk of contaminating the internal medium of the pipeline is smaller.
