Description

Technical Field

[0001] This utility model relates to the field of pipe joint disassembly technology, specifically a device for disconnecting large-diameter socket pipe joints. Background Technology

[0002] Pipe socket joints are a commonly used type of pipe connection. For large-diameter socket pipes, after installation, there may be issues such as watertightness failure, damage, or damage to the socket joint of the pipe section, requiring removal and replacement / repair. Due to the large diameter, the disengagement resistance is high, requiring significant external force to separate the pipe.

[0003] Using large mechanical equipment to drag and disconnect pipe sections often disturbs and affects other installed pipe sections, which can easily cause other unforeseen accidents. Moreover, disconnection often fails, consuming a lot of manpower and resources and ultimately resorting to destructive disconnection methods, resulting in significant losses. Therefore, using a simple and effective disconnection device can ensure smooth disconnection and avoid unnecessary losses and consumption. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this embodiment proposes a large-diameter socket pipe interface disconnection device, including two sets of steel ring clamps 1. Each set of steel ring clamps 1 has a connecting seat 2 welded to both ends. The surface of the connecting seat 2 is welded with a stiffening ring 3. One set of steel ring clamps 1 has a jack support 4 welded to its surface, and the other set of steel ring clamps 1 has a jack top seat 5 welded to its surface. The steel ring clamps 1 are the main structure of the device, which is assembled into a solid closed loop by unit ring clamp components with identical structural forms. The stiffening ring 3 is set to ensure the overall rigidity of the ring clamps. By adjusting the distance and position of the steel ring clamps 1 at both ends, the steel ring clamps 1 are rotated circumferentially so that the jack supports 4 and jack top seats 5 on both sides are parallel to the pipe axis, so that the distance and position between the two ring clamps are suitable for operation.

[0023] A limiting groove 6 is provided on one side of the jack support 4. A limiting block 7 is inserted into the limiting groove 6. A jack 8 is fixedly installed on one side of the limiting block 7. A top plate 9 is fixedly installed on one end of the jack 8. A threaded hole is provided on one side of the jack support 4. A push bolt 10 is threaded inside the threaded hole. The push bolt 10 is tightly abutted against the limiting block 7. After the steel ring 1 is installed, the jack 8 can be installed in each jack support 4 and fixed by the push bolt 10. When the jack 8 is working, the top plate 9 can be aligned with the jack top seat 5 and apply force to it to achieve the disengagement effect of the pipe joint.

[0024] The surface of the connector 2 is provided with a socket, and a fastening bolt 11 is inserted into the socket. Tightening the fastening bolt 11 will firmly fix the ring to the pipe. The inside of the steel ring 1 is provided with a strip rubber pad 12. The strip rubber pad 12 inside the ring is to protect the pipe and stabilize the ring.

[0025] One set of steel ring clamps 1 has the pipe joint socket end 13 inside, and the other set of steel ring clamps 1 has the pipe joint spigot end 14 inside. After the interface is separated, the jack 8 is removed, the steel ring clamps 1 are disassembled, and the strip rubber gasket 12 is recovered. The entire pipe joint disconnection process is completed.

[0026] Specifically, when this large-diameter socket joint disconnection device is in operation / use: It is used with various large-diameter fiberglass reinforced plastic (FRP) pipes, ductile iron pipes, PCCP, and other socket joint pipes. First, the steel ring clamps 1 are assembled into ring clamps and then installed and fixed at both ends of the socket joint to be disconnected. No working pit is required; the joint disconnection can be completed entirely manually. It is suitable for disconnecting joints of various large-diameter socket pipes, is not limited by site conditions, and is simple to manufacture and operate.
