Description

Technical Field

[0001] The present application relates to the technical field of water conservancy pipelines, and in particular to a locking device for pipe jacking connection. Background Art

[0002] Pipe jacking technology is now more and more widely used in pipe network systems, and the connection method between pipes is also a focus of current research. In the process of pipeline construction, it is common to connect through flanges or metal pipes through welding. This connection method is prone to deformation and falling off, pipe damage, and pipe locking when subjected to external pulling force or extrusion force. Since the horizontality of the pipe connection cannot be guaranteed, there is still a risk of leakage to a certain extent, and the quality of pipeline construction has been difficult to guarantee. Utility Model Content

[0003] In order to improve the above-mentioned problem, the present application provides a locking device for pipe jacking connection.

[0004] The locking device for pipe jacking connection provided in the present application adopts the following technical solution:

[0005] A locking device for pipe jacking connection, wherein a pipe mother port and a pipe sub-port are respectively provided at both ends of the pipe body, and the pipe mother port is plug-fitted with the pipe sub-port; the locking device comprises a locking protrusion elastically connected to the outside of the pipe sub-port, and a locking hole for inserting the locking protrusion is provided on the peripheral wall of the pipe mother port. The locking device is used to connect the pipe sub-port and the pipe mother port, which is beneficial to the firmness of the connection between the pipe mother-sub-port and the pipe mother port and the horizontality of the pipe connection, and helps to avoid the displacement and damage of the pipe due to external pulling or squeezing force. In the later process of pipeline maintenance, it can be disassembled from the locking device, which provides convenience for later maintenance.

[0006] Furthermore, an elastic member is arranged on one side of the locking protrusion close to the pipe spout, and the arrangement of the elastic member is conducive to better insertion of the locking protrusion into the locking hole.

[0007] Furthermore, the elastic member is a compression spring, and when the pipe female port squeezes the locking protrusion to compress the compression spring, the compression spring does not reach the maximum elastic deformation.

[0008] Furthermore, the locking projection has a side facing the adjacent pipe in an arc shape, which helps the locking projection to shrink more elastically.

[0009] Furthermore, the locking devices are evenly distributed on the pipeline, and at least two are provided.

[0010] Furthermore, a protective cover is provided on the outside of the pipe where the locking hole is located. The provision of the protective cover helps to prevent the locking protrusion from shrinking inwards due to squeezing of the pipe. When the connection between two adjacent pipes needs to be released, the protective cover is removed from the pipe, and the locking protrusion is pressed inwards by external force to make the locking protrusion fall out of the locking hole, thereby releasing the connection between the two adjacent pipes.

[0011] Furthermore, a rubber water-stop sleeve is arranged on the pipe sub-mouth, and a water-stop sleeve groove matching with the rubber water-stop sleeve is arranged on the pipe mother mouth. The arrangement of the rubber water-stop sleeve helps to prevent pipe leakage.

[0012] Furthermore, the rubber waterproof sleeve includes a first rubber waterproof sleeve and a second rubber waterproof sleeve, the waterproof sleeve groove includes a first waterproof sleeve groove and a second waterproof sleeve groove, the first rubber waterproof sleeve is matched with the first waterproof sleeve groove, and the second rubber waterproof sleeve is matched with the second waterproof sleeve groove. The double-layer rubber waterproof sleeve can better prevent leakage.

[0013] In summary, the present application includes at least one of the following beneficial technical effects:

[0014] 1. The utility model solves the problem that in the traditional pipeline connection process, the pipeline is easily offset and misaligned, resulting in pipeline damage.

[0015] 2. The entire connection structure of the utility model is easy to install and saves time, and is convenient for construction during the construction process.

[0016] 3. The utility model adds a double-layer waterproof rubber sleeve to effectively prevent the problem of pipeline leakage.

[0017] 4. After the pipes in the entire pipeline of the utility model are connected, they are not in a locked state, but in a movable state. However, the setting of the locking device can limit the movable limit between the pipes, thereby ensuring the horizontality of the pipe connection to a large extent; in the future maintenance process, disassembly is convenient and easy.

[0026] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0027] like Figure 1 , Figure 2 , Figure 4 As shown, a locking device for connecting a pipe jacking pipe, a pipe mother port 5 and a pipe sub-port 1 are respectively provided at both ends of the pipe body, and the pipe mother port 5 is plugged and adapted to the pipe sub-port 1; the locking device includes a locking protrusion 2 elastically connected to the outside of the pipe sub-port 1, and a locking hole 6 for the locking protrusion 2 to be inserted is provided on the peripheral wall of the pipe mother port 5. The locking device is used to connect the pipe sub-port 1 and the pipe mother port 5, which is beneficial to the firmness of the connection between the pipe mother-sub-port and the horizontality of the pipe connection, and helps to avoid the displacement and damage of the pipe due to external pulling or squeezing force. In the later process of pipeline maintenance, it can be disassembled from the locking device, which provides convenience for later maintenance.

[0028] like Figure 3As shown, an elastic member is arranged on the side of the locking protrusion 2 close to the pipe sub-mouth. The arrangement of the elastic member facilitates the locking protrusion 2 to be better inserted into the locking hole 6. The elastic member is a compression spring 10. When the pipe female mouth 5 squeezes the locking protrusion 2 to compress the compression spring 10, the compression spring 10 does not reach the maximum elastic deformation. The side of the locking protrusion 2 facing the adjacent pipe is arc-shaped. The arc-shaped arrangement helps the locking protrusion 2 to have better elastic contraction.

[0029] like Figure 1 , Figure 2 As shown, the locking devices are evenly distributed on the pipeline, and three of them are provided.

[0030] like Figure 2 , Figure 4 As shown, a protective cover 7 is provided on the outside of the pipe where the locking hole 6 is located, and the protective cover 7 is fixed to the outside of the pipe by bolts and nuts. The provision of the protective cover 7 helps to prevent the locking protrusion 2 from shrinking inwards due to squeezing of the pipe. When the connection between two adjacent pipes needs to be released, the protective cover 7 is removed from the pipe, and the locking protrusion 2 is pressed inwards by external force to make the locking protrusion 2 fall out of the locking hole 6, thereby releasing the connection between the two adjacent pipes.

[0031] like Figure 1 , Figure 2 As shown, a rubber water stop sleeve is arranged on the pipe sub-mouth 1, and a water stop sleeve groove matching with the rubber water stop sleeve is arranged on the pipe female mouth 5. The arrangement of the rubber water stop sleeve helps to prevent pipe leakage.

[0032] like Figure 1 , Figure 2 , Figure 4 As shown, the rubber waterproof sleeve includes a first rubber waterproof sleeve 3 and a second rubber waterproof sleeve 4, the waterproof sleeve groove includes a first waterproof sleeve groove 8 and a second waterproof sleeve groove 9, the first rubber waterproof sleeve 3 is matched with the first waterproof sleeve groove 8, and the second rubber waterproof sleeve 4 is matched with the second waterproof sleeve groove 9. Setting a double-layer rubber waterproof sleeve can better prevent leakage.

[0033] The entire connection structure of the present application is convenient and time-saving to install, and is easy to construct during the construction process, which is beneficial to the firmness of the pipe male and female connection and the horizontality of the pipe connection, and helps to avoid the deviation and damage of the pipe due to external pulling or squeezing force. The double-layer rubber water stop sleeve is set at the connection port, which can also effectively solve the leakage problem and largely ensure the quality of the top pipe connection.

[0034] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
