Description

Technical Field

[0001] This utility model relates to the field of municipal pipeline technology, specifically to an auxiliary device for backfilling municipal pipeline trenches. Background Technology

[0002] In the field of municipal pipeline trench backfilling construction, existing technologies mostly use manual protection or simple shielding methods to protect pipelines. When using manual protection, construction workers need to hold wooden boards, canvases and other materials and place them around the pipeline in the trench to form a temporary shield. The simple shielding method is to directly cover the pipeline surface with flexible materials such as plastic sheeting and tarpaulin before carrying out soil backfilling, thereby reducing the direct contact between soil and pipeline.

[0003] However, existing technologies have significant shortcomings: First, they offer poor protection and low reliability. Manually placed materials such as wooden boards and canvas are difficult to adhere tightly to the pipe surface and are easily displaced by soil impact during backfilling, failing to form a continuous and stable protective barrier. Materials such as plastic sheeting and tarpaulin have low strength and are easily torn by sharp stones and debris, causing soil to directly contact and compress the outer wall of the pipe, resulting in scratches, deformation, or even damage, making it difficult to ensure the integrity of the pipe structure. Second, the operation is cumbersome and inefficient. Manually placing protective materials in the trench requires a large amount of manpower, and due to the limited space in the trench, the protection range cannot fully cover the pipe. The position of the protective materials also needs to be frequently adjusted during backfilling, affecting the progress of the backfilling operation. Utility Model Content

[0004] The problem to be solved by this utility model is to provide an auxiliary device for backfilling municipal pipeline trenches. This utility model has reliable pipeline protection performance. The flexible guide curtain can fit the pipeline surface under the action of the counterweight to form a flexible protective barrier, which avoids the soil from directly impacting and squeezing the outer wall of the pipeline during backfilling, effectively reducing pipeline damage and ensuring the integrity of the pipeline structure.

[0005] The technical solution provided by this utility model to solve the above problems is as follows: an auxiliary device for backfilling municipal pipeline trenches, including a receiving pipe, a mounting base, a lifting ring, and a connecting rope. The mounting bases are symmetrically arranged and fixed to the top of the receiving pipe. The lifting rings are connected between the mounting bases through the connecting rope. It also includes a protective component and a flow guiding component. The protective component is used to protect the pipeline during pipeline trench backfilling, and the flow guiding component is used to guide the filling soil.

[0006] More preferably, the protective assembly includes a rotating component, a flexible guide curtain, and a counterweight. The rotating component is rotatably connected to the storage tube, the flexible guide curtain is wound around the rotating component and stored in the storage tube, and the counterweight is installed at the bottom of the flexible guide curtain.

[0007] More preferably, the flexible guide curtain can hang on the pipe under the action of the counterweight, thereby protecting the pipe and guiding the soil.

[0008] More preferably, the flow guiding assembly includes connectors, pull ropes, inclined plates, mounting plates, and elastic elements. The symmetrically arranged connectors are fixed to the bottom of the receiving tube. The symmetrically arranged inclined plates are all connected to the bottom of the corresponding connectors by pull ropes. The symmetrically arranged mounting plates are fixed to the side of the receiving tube. The inclined plates have receiving grooves that cooperate with the mounting plates. Each mounting plate is glued with symmetrically arranged elastic elements.

[0009] More preferably, the inclined plate is used to guide the filling soil, so that the soil can preferentially fill the sides of the pipe.

[0010] More preferably, the mounting plate is used to store the inclined plate, and the elastic element is used to limit the movement of the inclined plate.

[0011] Compared with the prior art, the advantages of this utility model are: this utility model has reliable pipeline protection performance. The flexible guide curtain can fit the pipeline surface under the action of the counterweight to form a flexible protective barrier, which avoids the soil from directly impacting and squeezing the outer wall of the pipeline during backfilling, effectively reducing pipeline damage and ensuring the integrity of the pipeline structure.

[0012] The flow guiding effect is significant. The symmetrically set inclined plates can guide the backfill soil to fill the gaps on the side of the pipe first, avoiding problems such as uneven soil accumulation and voids at the bottom of the pipe. At the same time, the flexible guide curtain can assist in the flow guiding, improve the compaction of the trench backfill, and ensure the quality of backfilling.

[0013] Convenient to store and use, the flexible guide curtain can be rolled up and stored in the storage tube through the rotating part, and the inclined plate can be snapped onto the mounting plate through the storage slot and limited by the elastic part. The whole component is compact after storage, which is convenient for handling, transportation and reuse, and reduces operating costs.

[0014] With strong structural stability, the device can be stably suspended from external equipment through the cooperation of the lifting ring, connecting rope and mounting base, and it is not easy to shake during operation; the pull rope plays a role in suspending and limiting the inclined plate, and the elastic element ensures the stability of the inclined plate in working state, ensuring that the protection and diversion functions are performed in an orderly manner.

[0025] Example: As shown in the attached figure, a municipal pipeline trench backfilling auxiliary device includes a receiving pipe 1, a mounting base 2, a lifting ring 3, and a connecting rope 4. The symmetrically arranged mounting bases 2 are fixed to the top of the receiving pipe 1. The lifting rings 3 are connected to the mounting bases 2 through the connecting rope 4. The lifting rings 3 are installed on an external device. It also includes a protective component and a flow guiding component. The protective component is used to protect the pipeline during pipeline trench backfilling, and the flow guiding component is used to guide the filling soil.

[0026] In this embodiment, the protective component specifically includes a rotating member 5, a flexible guide curtain 6, and a counterweight 7. The rotating member 5 is rotatably connected to the receiving tube 1. The flexible guide curtain 6 is wound around the rotating member 5 and stored in the receiving tube 1. The counterweight 7 is installed at the bottom of the flexible guide curtain 6. Under the action of the counterweight 7, the flexible guide curtain 6 can hang on the pipe, thereby protecting the pipe and guiding the soil. Furthermore, the flow guiding assembly includes connectors 8, pull ropes 9, inclined plates 10, mounting plates 11, and elastic elements 12. The symmetrically arranged connectors 8 are fixed to the bottom of the receiving pipe 1. The symmetrically arranged inclined plates 10 are all connected to the bottom of the corresponding connectors 8 through pull ropes 9. The inclined plates 10 are used to guide the filling soil, so that the soil can preferentially fill the side of the pipe. The symmetrically arranged mounting plates 11 are fixed to the side of the receiving pipe 1. The inclined plates 10 are provided with receiving grooves that cooperate with the mounting plates 11. The mounting plates 11 are used to receive the inclined plates 10. Each mounting plate 11 is attached with symmetrically arranged elastic elements 12. The elastic elements 12 are used to limit the movement of the inclined plates 10.

[0027] When using this municipal pipeline trench backfilling auxiliary device, the device is hoisted to the external equipment using the lifting ring 3. The moving device is positioned so that the receiving pipe 1 is directly above the pipeline in the trench. The connecting rope 4 and the mounting base 2 are used to ensure that the device is suspended stably.

[0028] Rotating the rotating component 5 releases the flexible guide curtain 6 inside the receiving pipe 1. Under the gravity of the counterweight 7, the flexible guide curtain 6 naturally hangs down and adheres to the pipe surface, forming a protective barrier to prevent soil from directly impacting the outer wall of the pipe during backfilling, reducing damage to the pipe caused by collisions and compression. At the same time, the flexible guide curtain 6 can guide some soil to flow to both sides of the pipe, assisting in flow guidance. Pulling the inclined plate 10 detaches it from the mounting plate 11. The pull rope 9 suspends and limits the inclined plate 10. The symmetrically arranged inclined plates 10 are in an inclined state. During backfilling, soil falls onto the inclined plate 10 and is guided by the inclined plate 10 to preferentially fill the gaps on the side of the pipe, avoiding uneven soil accumulation and gaps at the bottom of the pipe, and ensuring the compaction of the backfill.

[0029] After backfilling is completed, the rotating component 5 can be rotated in the opposite direction to roll up and store the flexible guide curtain 6 into the receiving pipe 1, and the inclined plate 10 can be secured to the mounting plate 11. The elastic component 12 limits the inclined plate 10, enabling the components to be quickly stored, facilitating the handling and reuse of the device. Throughout the process, the protective components and the flow guiding components work together to protect the integrity of the pipeline and improve the efficiency and quality of trench backfilling.

[0030] The above description only illustrates the preferred embodiment of this utility model and should not be construed as limiting the claims. This utility model is not limited to the above embodiments, and variations in its specific structure are permitted. All changes made within the scope of the independent claims of this utility model are also within the scope of protection of this utility model.
