Description

Technical Field

[0001] This application relates to the technical field of engineering auxiliary equipment, and in particular to a docking auxiliary device for rapid installation of municipal pipelines. Background Technology

[0002] In municipal drainage projects, socket-type pipes and inspection wells are generally used together to facilitate the inspection and maintenance of the entire drainage pipeline after use. In order to improve construction efficiency and reduce road occupancy time, both socket-type pipes and inspection wells are precast concrete components, which can significantly reduce the total amount and number of grouting during use.

[0003] When installing pipes and manholes, it is generally necessary to do so after the manhole has been grouted. Operators use a hoist to lift the pipe, and the operators in the pit align one end of the pipe with the pre-drilled hole in the manhole to insert it for installation. Due to the weight of the pipe and the difficulty of alignment, the step of inserting the pipe into the manhole is time-consuming and inefficient. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a docking auxiliary device for rapid installation of municipal pipelines. In this embodiment, a detachable ring and a conical guide are used. The conical guide enables the pipeline to be quickly aligned with the pre-drilled hole in the inspection well, thereby reducing the alignment time for operators and significantly improving the efficiency of connecting the pipeline to the inspection well. Furthermore, the arc-shaped installation block left during dismantling can also alleviate the problem of pipeline eccentricity.

[0005] The above-mentioned objective of this application is achieved through the following technical solution:

[0006] A docking auxiliary device for rapid installation of municipal pipelines includes a ring sleeve and a guide body installed on one side of the ring sleeve;

[0007] The ring includes an arc-shaped mounting block and an adjustable connecting strip. The thickness of the connecting strip is less than the thickness of the arc-shaped mounting block, and the two ends of the connecting strip are detachably connected to the two ends of the arc-shaped mounting block, respectively.

[0008] The guide body is detachably connected to one side of the ring sleeve, and the diameter of the guide body gradually decreases in the direction away from the ring sleeve;

[0009] In the assembled state, the two ends of the connecting strip are connected to the two ends of the arc-shaped mounting block, so that the connecting strip and the arc-shaped mounting block form a loop that can loop around the pipe.

[0010] Optionally, the connecting strip is equipped with several connecting posts, and the guide body has several connecting grooves on the side near the connecting strip. In the assembled state, the several connecting posts are inserted into the several connecting grooves respectively, so that the connecting strip and the guide body form a detachable connection.

[0011] Optionally, the guide body can be a hollow structure.

[0012] Optionally, the hollow guide body includes an annular frame, a conical frame fixed to one side of the annular frame, and a skin fixed to the outside of the annular frame and the conical frame, wherein the outer diameter of the conical frame gradually decreases in the direction away from the annular frame.

[0013] Optionally, several sleeves are fixed to one side of the ring frame near the connecting belt. The sleeves are hollow inside and open at both ends, and the internal area of ​​the sleeve is a connecting groove.

[0014] Optionally, the two ends of the arc-shaped mounting block are provided with T-shaped grooves, and the two ends of the connecting strip are fixed with T-shaped connectors. In the assembled state, the T-shaped connectors at both ends of the connecting strip are respectively inserted into the T-shaped grooves at both ends of the arc-shaped mounting block to form a detachable connection.

[0015] Optionally, a fixing plate is fixed to one end of the T-shaped connector near the guide body. In the assembled state, the fixing plate is bolted to the arc-shaped mounting block.

[0019] This application embodiment uses a detachable ring and a conical guide. The conical guide allows for quick alignment of the pipe with the pre-drilled hole in the inspection well, reducing the alignment time for operators and significantly improving the efficiency of pipe-inspection connection.

[0029] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0030] This application provides a docking auxiliary device for rapid installation of municipal pipelines, including a ring sleeve 10 and a guide body 20 installed on one side of the ring sleeve 10;

[0031] The ring 10 includes an arc-shaped mounting block 11 and an adjustable connecting strip 12. The thickness of the connecting strip 12 is less than the thickness of the arc-shaped mounting block 11. The two ends of the connecting strip 12 are detachably connected to the two ends of the arc-shaped mounting block 11.

[0032] The guide body 20 is detachably connected to one side of the ring sleeve 10. The diameter of the guide body 20 gradually decreases in the direction away from the ring sleeve 10, and the end of the guide body 20 away from the ring sleeve 10 is the distal end.

[0033] In the assembled state, the two ends of the connecting strip 12 are respectively connected to the two ends of the arc-shaped mounting block 11, so that the connecting strip 12 and the arc-shaped mounting block 11 form a ring 10 that can loop around the pipe 10.

[0034] The following section will provide further details based on specific usage scenarios.

[0035] When in use, the operator fixes the inspection well and the hoisting pipe according to the operating specifications. After the preliminary steps are completed, the connecting belt 12 is first used to put the ring 10 on the pipe that needs to enter the reserved hole of the inspection well. At this time, the ring 10 is put on the outside of the pipe near the inspection well, and the lip seal on the outside of the pipe is on the side of the ring 10 away from the inspection well.

[0036] Because the distal diameter of the guide body 20 is small, the operator can first insert the distal end of the guide body 20 into the pre-drilled hole of the inspection well. As the operator continues to advance the pipeline, the outer diameter of the guide body 20 gradually decreases in the direction away from the pipeline. The conical guide body 20 guides the central axis of the pipeline to gradually become parallel to the central axis of the inspection well, thereby reducing the time for the operator to align and significantly improving the efficiency of the connection between the pipeline and the inspection well.

[0037] Furthermore, since the connecting strap 12 of the 10-type ring is detachably connected to the arc-shaped mounting block 11, during installation, the arc-shaped mounting block 11 is located at the bottom of the pipe. The thickness of the arc-shaped mounting block 11 is greater than the rear of the connecting strap 12. After the pipe is inside the pre-drilled hole in the inspection well, the operator can slightly loosen the lifting device, allowing the arc-shaped mounting block 11 to support the pipe. At this point, the operator can quickly remove the connecting strap 12 without removing the arc-shaped mounting block 11. The presence of the arc-shaped mounting block 11 also alleviates the problem of... Figure 2 The eccentricity problem shown.

[0038] In summary, the embodiments of this application utilize a detachable ring 10 and a conical guide 20. The conical guide 20 enables the pipe to be quickly aligned with the pre-drilled hole in the inspection well, thereby reducing the alignment time for operators and significantly improving the efficiency of the connection between the pipe and the inspection well. Furthermore, the arc-shaped installation block 11 left during dismantling can also alleviate the problem of pipe eccentricity.

[0039] In this embodiment, the guide body 20 and the ring sleeve 10 are detachably connected. In this embodiment, several connecting posts 13 can be welded to the outside of the connecting band 12, and several connecting grooves 25 adapted to the connecting posts 13 can be opened on the side of the guide body 20 near the connecting band 12. In the assembled state, several connecting posts 13 are respectively inserted into several connecting grooves 25, thereby realizing the detachable connection between the connecting band 12 and the guide body 20. In this way, the operator spends less time and has higher efficiency in the process of installation, use and disassembly.

[0040] It should be noted that during use, apart from gravity and the force exerted by the operator during disassembly, the guide body 20 is basically not subjected to stress away from the pipeline, and this simple detachable connection method can meet the requirements.

[0041] In this embodiment, the guide body 20 is a hollow structure to reduce its weight and facilitate installation and disassembly by operators. Specifically, the hollow guide body 20 includes an annular frame 21, a conical frame 22 fixed to one side of the annular frame 21, and a skin 23 fixed to the outside of the annular frame 21 and the conical frame 22. The outer diameter of the conical frame 22 gradually decreases in the direction away from the ring sleeve 10. The annular frame 21 and the conical frame 22 can be formed by welding steel bars. Through the setting of the internal skeleton and the skin 23, the hollow structure of the guide body 20 is realized, which facilitates installation and disassembly by operators.

[0042] Based on this, several sleeves 24 are fixedly connected to the side of the ring frame 21 near the connecting belt 12. The sleeves 24 are hollow inside and open at both ends. The internal area of ​​the sleeves 24 is the connecting groove 25.

[0043] In this embodiment, the connecting strip 12 is detachably connected to the arc-shaped mounting block 11. Based on this, T-shaped grooves 14 can be opened at both ends of the arc-shaped mounting block 11 in this embodiment. T-shaped connectors 15 are fixedly connected to both ends of the connecting strip 12. In the assembled state, the T-shaped connectors 15 at both ends of the connecting strip 12 are respectively inserted into the T-shaped grooves 14 at both ends of the arc-shaped mounting block 11 to form a detachable connection. The connection method is reliable and easy to assemble and disassemble.

[0044] Based on this, a fixing piece 16 is fixedly connected to one end of the T-shaped connector 15 near the guide body 20. In the assembled state, the fixing piece 16 is bolted to the arc-shaped mounting block 11 to further improve the stability of the auxiliary device in the assembled state.

[0045] In this embodiment, an adjustable anti-slip plate 17 can also be fixed to the inner side of the connecting band 12. The anti-slip plate 17 is elastic and there are several anti-slip plates 17. The several anti-slip plates 17 are independent of each other. When the connecting band 12 is unfolded, there is a gap between two adjacent anti-slip plates 17. In this way, when the connecting band 12 and the arc-shaped mounting block 11 form a ring 10, the anti-slip plate 17 can form a friction pair with the outside of the pipe, which significantly improves the stability of the connection between the device and the pipe. The gap between two anti-slip plates 17 can also provide a deformation space margin for the elastic deformation of the anti-slip plate 17.

[0046] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
