Description

Technical Field

[0001] The utility model relates to the field of underground pipelines, and particularly relates to a plugging device for underground pipeline construction. Background Technique

[0002] During the construction of the underground pipe network, the pipe connection is fixed by inserting the end of the socket at the front end of the pipe into the spigot. When installing the pipe during intermittent construction (continuous construction during the day and suspension at night), in order to ensure the cleanliness of the construction pipe network and prevent surrounding debris from entering, it is necessary to block the front end of the pipe with a baffle at the end of the day's construction. The existing plugging is carried out by covering a layer of plastic cloth, but this kind of covering is vulnerable to impact and is easily blown away by strong winds, affecting the plugging effect. Content of the Utility Model

[0003] In order to solve the above existing problems, the utility model provides a plugging device for underground pipeline construction.

[0004] The utility model is realized through the following technical solutions:

[0005] A plugging device for underground pipeline construction includes a pipeline buried underground. A socket is provided at the front end of the pipeline, and a plugging end cover is provided on the end face of the socket. A plurality of elastic support components are evenly arranged in a ring inside the plugging end cover. The plugging end cover can be supported and fixed with the socket through the compression support of the plurality of elastic support components.

[0006] Further optionally, the elastic support component includes a support plate fixed to the inner side of the plugging end cover. The end of the support plate is hinged and fixed to a pressing block through a connecting rod, and a plurality of compression springs are connected between the pressing block and the support plate.

[0007] Further optionally, the support plate, the pressing block and the plugging end cover are perpendicular to each other, and there is a telescopic distance between the end of the pressing block and the plugging end cover.

[0008] Further optionally, a layer of hard rubber layer that fits the inner wall of the socket is bonded to the top of the pressing block.

[0009] Further optionally, a plurality of cross - arranged reinforcing plates are fixed to the outside of the plugging end cover.

[0010] Further optionally, a handle for convenient movement and lifting is fixed to the outside of the plugging end cover.

[0011] Further optionally, the connecting rod is inclined downward.

[0012] Compared with the existing technologies, the beneficial effects of the present utility model are as follows: By arranging a sealing end cover at the socket of the pipeline and installing a plurality of compressed elastic support components inside the sealing end cover, it is ensured that the sealing end cover can be firmly fixed to the socket, achieving a firm sealing of the pipeline sealing end cover.

[0019] The present utility model will be further described in detail below in conjunction with the drawings and the specific embodiments:

[0020] As Figure 1 , 2 shown, an underground pipeline construction plugging device includes a pipeline 1 buried underground. A socket 2 is provided at the front end of the pipeline 1. A sealing end cover 3 is provided on the end face of the socket 2. A plurality of elastic support components 6 are evenly arranged in a ring inside the sealing end cover 3. The sealing end cover 3 can be supported and fixed to the socket 2 through the compression support of the plurality of elastic support components 6.

[0021] As Figure 3 shown, the elastic support component 6 includes a support plate 7 fixed inside the sealing end cover 3. The end of the support plate 7 is hinged and fixed to a pressing block 10 through a connecting rod 8. The connecting rod 8 is hinged through a pin shaft 9. A plurality of compression springs 11 are connected between the pressing block 10 and the support plate 7. The compression springs 11 play a role in supporting and contracting the pressing block 10, so that it can always keep in close contact with the inner wall of the socket.

[0022] As Figure 4As shown, the support plate 7 and the pressing block 10 are perpendicular to the sealing end cover 3. There is a telescopic distance between the end of the pressing block 10 and the sealing end cover 3, which avoids interference between the pressing block 10 and the sealing end cover 3 when the pressing block 10 contracts. A layer of hard rubber layer that fits the inner wall of the socket 2 is bonded to the top of the pressing block 10. The hard rubber layer prevents the pressing block 10 from directly contacting the socket 2 and prevents the pressing block 10 from being worn.

[0023] As Figure 1 shown, a plurality of reinforcing plates 5 arranged crosswise are fixed to the outside of the sealing end cover 3 to prevent the sealing end cover 3 from deforming.

[0024] As Figure 1 shown, a handle 4 for facilitating movement and lifting is fixed to the outside of the sealing end cover 3.

[0025] As Figure 4 shown, the connecting rod 8 is arranged obliquely downward. The oblique downward setting is equivalent to forming an inclination angle, which is convenient for insertion and has a guiding effect.

[0026] The implementation principle of the underground pipeline construction plugging device in the embodiment of the present application is as follows:

[0027] When it is necessary to plug the socket 2 at the very front end during the installation of the pipeline 1 (as Figure 4 , 5 shown), the plugging personnel hold both sides of the handle 4 to lift and move the sealing end cover 3 to the side of the socket 2 at the front end of the corresponding pipeline 1, align the plurality of elastic support components 6 of the sealing end cover 3 with the socket 2, and apply pressure to press the elastic support components 6 into the socket 2 to achieve support and fixation;

[0028] When the elastic support component 6 is pressed into the socket 2, the inclined connecting rod 8 plays a guiding role to ensure that its front end can smoothly enter the inner side of the socket 2. When the connecting rod 8 extends into the inner side of the socket 2 and makes contact, the middle part of the connecting rod 8 will be inclined and move towards the support plate 7 under the extrusion of the inner side of the socket 2. During the inclined movement, it will drive the pressing block 10 to press and incline downward until the pressing block 10 enters the inner side of the socket 2. When the pressing block 10 completely enters the socket 2, the compression spring 11 is in a compressed state. The compression spring 11 ensures that the pressing block 10 can always fit and press tightly against the inner wall of the socket 2, prevents the pressing block 10 from detaching from the socket 2, ensures the support of the entire elastic support component 6, and realizes the reliable plugging of the sealing end cover 3.
