Description

Technical Field

[0001] The utility model relates to the technical field of municipal pipeline engineering, and particularly relates to a jacking pipe plugging device for municipal pipeline construction. Background Technique

[0002] With the continuous acceleration of the urbanization process, the number of residents in the city is increasing day by day. At the same time, in order to meet the needs of people's daily life, the pipeline facilities in the city are also increasing continuously. The construction of pipelines provides great convenience for people's lives. When pipelines are constructed, a part of the pipelines needs to be plugged;

[0003] The Chinese patent (publication number: CN215617500U) discloses an airbag plugging external jacking pipe device, which includes a cover plate covering the outer end face of the pipe body. A threaded hole is opened in the center of the cover plate, and a hollow-structured adjusting screw rod is inserted into the threaded hole. One end of the adjusting screw rod is installed with a handle, and the other end is installed with an airbag for extending into the pipe body. A micro air pump is installed on one side of the handle, and the output end of the micro air pump is communicated with the inside of the adjusting screw rod through a conduit; symmetrically installed on both ends of the cover plate are threaded columns extending outwards, and positioning components for clamping both sides of the pipe body are respectively installed on the two threaded columns. This utility model uses an airbag structure to plug the inner cavity of the pipe body, with good sealing performance. Moreover, the airbag can adjust its depth in the pipe body under the control of the adjusting screw rod, facilitating flexible adjustment of its plugging position; the positioning components are used to clamp both sides of the pipe body, facilitating the stable installation of the whole device, easy disassembly and assembly, and strong flexibility. However, in the actual use process, the position of the clamping block cannot be adjusted. When it is close to the pipe orifice, the accumulated water in the water pipe leaks outwards or will fall off from the water pipe after being impacted by water, with poor stability. Moreover, the position of the airbag cannot be detected, and the airbag deviation cannot be found in time, there is a risk of leakage, which is not conducive to the plugging use of the jacking pipe. Therefore, a jacking pipe plugging device for municipal pipeline construction is proposed. Content of the Utility Model

[0004] In view of this, the utility model provides a jacking pipe plugging device for municipal pipeline construction to solve or alleviate the technical problems existing in the prior art, and at least provide a beneficial choice.

[0005] The technical solution of the utility model is realized as follows: A jacking pipe plugging device for municipal pipeline construction includes a plugging mechanism, a fixing mechanism, a clamp and a pipe body. The fixing mechanism is installed outside the plugging mechanism, the pipe body is installed at the bottom of the plugging mechanism, and the clamp is sleeved outside the pipe body;

[0006] The plugging mechanism includes a cover plate, and an air delivery pipe is communicated with the upper surface of the cover plate. One end of the air delivery pipe penetrates through the cover plate, and one end of the air delivery pipe is communicated with a sealing airbag;

[0007] Four first fixing blocks are symmetrically and fixedly connected to the outer side wall of the cover plate. A through hole is formed in the upper surface of the first fixing block. The inner side wall of the through hole is slidably connected with a first threaded rod. Nuts are threadedly connected to both the top and bottom of the first fixing block on the outer side wall of the first threaded rod. A second fixing block is fixedly connected to the bottom of the first threaded rod. A threaded hole is formed in one side of the second fixing block. The inner side wall of the threaded hole is threadedly connected with a second threaded rod. One end of the second threaded rod is rotatably connected with an arc-shaped plate through a bearing. Four pressure sensors are symmetrically installed at the bottom of the clamp. The arc-shaped plate corresponds to the position of the pressure sensor.

[0008] Further preferably, a sealing gasket is adhesively bonded to the lower surface of the cover plate.

[0009] Further preferably, a knob is fixedly connected to one end of the second threaded rod.

[0010] Further preferably, an alarm is installed on the upper surface of the cover plate.

[0011] Further preferably, a controller is installed on the upper surface of the cover plate. The pressure sensor is signal-connected to the controller, and the controller is electrically connected to the alarm.

[0012] Further preferably, a valve is installed on the gas transmission pipe.

[0013] Since the embodiment of the present utility model adopts the above technical solutions, it has the following advantages:

[0014] During the use of the present utility model, by adjusting the position of the arc-shaped plate, the arc-shaped plate is moved away from the pipe orifice of the pipe body, reducing the risk of detachment. If the sealing airbag generates a position offset, the arc-shaped plate presses the pressure sensor at the bottom of the clamp, and an alarm is used for reminder. Moreover, the clamp restricts the position of the arc-shaped plate to prevent the arc-shaped plate from detaching from the pipe body, detecting the position of the sealing airbag, improving safety, reducing the leakage risk, and being beneficial to the plugging use of the pipe jacking.

The fixing mechanism 2 is installed outside the plugging mechanism 1, the pipe body 4 is installed at the bottom of the plugging mechanism 1, and the clamp 3 is sleeved outside the pipe body 4;

[0025] The plugging mechanism 1 includes a cover plate 11. The upper surface of the cover plate 11 is communicated with a gas transmission pipe 12. One end of the gas transmission pipe 12 penetrates through the cover plate 11, and one end of the gas transmission pipe 12 is communicated with a sealing airbag 14;

[0026] Four first fixing blocks 21 are symmetrically and fixedly connected to the outer side wall of the cover plate 11. A through hole 22 is formed in the upper surface of the first fixing block 21. A first threaded rod 23 is slidably connected to the inner side wall of the through hole 22. Nuts 24 are threadedly connected to both the top and bottom of the first fixing block 21 on the outer side wall of the first threaded rod 23. A second fixing block 25 is fixedly connected to the bottom of the first threaded rod 23. A threaded hole 26 is formed in one side of the second fixing block 25. A second threaded rod 27 is threadedly connected to the inner side wall of the threaded hole 26. One end of the second threaded rod 27 is rotatably connected to an arc-shaped plate 29 through a bearing. Four pressure sensors 31 are symmetrically installed at the bottom of the clamp 3. The position of the arc-shaped plate 29 corresponds to that of the pressure sensors 31.

[0027] In one embodiment, a sealing gasket 15 is adhesively bonded to the lower surface of the cover plate 11; through the arrangement of the sealing gasket 15, the sealing effect between the cover plate 11 and the pipe body 4 is improved.

[0028] In one embodiment, one end of the second threaded rod 27 is fixedly connected to a knob 28; through the arrangement of the knob 28, it is convenient to rotate the second threaded rod 27.

[0029] In one embodiment, an alarm 33 is installed on the upper surface of the cover plate 11; through the arrangement of the alarm 33, when the position of the sealing airbag 14 is displaced, the alarm 33 is activated to remind the staff.

[0030] In one embodiment, a controller 32 is installed on the upper surface of the cover plate 11.
