Description

Technical Field

[0001] The utility model relates to the technical field of utility tunnels, in particular to a top hoisting structure for communication pipelines at the outlet of a utility tunnel. Background Art

[0002] With the popularization of utility tunnels, almost all utility tunnels will accommodate communication pipelines. In addition, the demand for the penetration of communication pipelines in both sides of the area is more frequent than that of other pipelines. Therefore, an outlet for communication pipelines needs to be made in each fire compartment. At present, at the outlet of communication pipelines, the top hoisting in the utility tunnel usually uses a mounting plate to support the pipelines; the invention patent CN111021412A discloses an underground utility tunnel. In order to realize the reasonable layout of pipelines, all pipelines inside the main utility tunnel are hoisted, and an arc-shaped plate is combined with a T-shaped mounting plate to install the pipelines in pairs on the top of the main utility tunnel. The arc-shaped plates bent upward at both ends can provide more stable supporting force for the pipelines to enhance the installation strength. When subjected to a large impact, the arc-shaped plates will undergo a certain elastic deformation, which can ensure that the pipelines will not slip off.

[0003] The inventor found that in the above pipeline layout form, the positions of the mounting plate and the T-shaped plate are fixed. Therefore, it is not convenient to adjust the different supporting positions of the pipelines, the flexibility is poor, and it will also cause the pipeline laying process to be more troublesome. In addition, when using arc-shaped plates to support the pipelines, when the pipelines need to be towed during the laying process, the pipelines will rub against the arc-shaped plates, which is easy to damage the pipelines. Summary of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the purpose of the utility model is to provide a top hoisting structure for communication pipelines at the outlet of a utility tunnel, so as to solve the problems that the supporting position of the pipelines in the prior art is inconvenient to adjust and the laying is inconvenient.

[0005] In order to achieve the above purpose, the utility model is realized by the following technical solutions:

[0006] A top hoisting structure for communication pipelines at the outlet of a utility tunnel includes a plurality of support columns. The support columns are connected by support rods to form a frame structure. The top ends of the support columns are used for fixedly connecting with embedded steel plates. A plurality of mutually parallel steel pipes are arranged inside the frame structure; both ends of the steel pipes are lapped on the support rods, and end-sealing steel plates are arranged at the ends of the steel pipes. The steel pipes are in sliding fit with the support rods by abutting against the side surfaces of the support rods through the end-sealing steel plates. Cable rack rollers are sleeved on the steel pipes, and the cable rack rollers can slide on the steel pipes.

[0007] Through the rotational cooperation between the cable rack roller and the steel pipe, it can ensure that the pipeline will not be damaged due to friction. During the process of laying and towing the pipeline, the structure can complete the rapid laying of the cable by changing different support positions; by changing the support position, it can also achieve better support for the pipeline, with strong flexibility.

[0008] As a further implementation method, the support column is vertically arranged with the support rod, and the end of the support column is connected to the support rod.

[0009] As a further implementation method, the top of the support column is higher than the support rod by a set distance.

[0010] As a further implementation method, the support column is made of H-shaped steel.

[0011] As a further implementation method, the support rod is made of angle steel.

[0012] As a further implementation method, the support column can be connected with multiple layers of support rod structures along the axial direction.

[0013] As a further implementation method, at least two columns of steel pipes are provided, and several steel pipes in each column are arranged in parallel.

[0014] As a further implementation method, fixing holes are evenly provided on the angle steel, and a fixing piece is fixed at the end of the steel pipe, and the fixing piece passes through the fixing hole to fix the position of the steel pipe.

[0015] As a further implementation method, the support rod includes a first support rod and a second support rod. Both ends of the first support rod and the second support rod are connected to the support column and are vertically arranged. The steel pipe is in sliding fit with the first support rod, and the steel pipe is parallel to the second support rod.

[0016] As a further implementation method, a group of support columns are shared between two adjacent columns of steel pipes, and first support rods are provided on both sides of the shared support column for cooperation with steel pipes in different columns.

[0017] The beneficial effects of the above-mentioned utility model are as follows:

[0018] 1. In the utility model, the steel pipe can slide along the support rod, which can change the longitudinal position of the cable rack roller. By sliding the cable rack roller along the steel pipe, the transverse position of the cable rack roller can be changed. Through the rotational cooperation between the cable rack roller and the steel pipe, it can ensure that the pipeline will not be damaged due to friction. During the process of laying and towing the pipeline, the structure can complete the rapid laying of the cable by changing different support positions; by changing the support position, it can also achieve better support for the pipeline, with strong flexibility.

[0019] 2. The setting of the end-sealing steel plate ensures that the steel pipe can slide along the first support rod, thereby changing different support positions.

[0031] It should be noted that the following detailed description is exemplary and is intended to provide further illustration of the present utility model. Unless otherwise specified, all technical and scientific terms used in the present utility model have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present utility model belongs.

[0032] Embodiment 1

[0033] In a typical embodiment of the present utility model, referring to Figures 1-7 As shown, a top hoisting structure for communication pipelines at the outlet of an integrated pipe gallery includes several support columns 3. The support columns 3 are connected by support rods to form a frame structure. The top ends of the support columns 3 are used for fixed connection with embedded steel plates 31. Inside the frame structure, several steel pipes 4 are arranged in parallel; both ends of the steel pipe 4 are lapped on the support rods. A sealing end steel plate 31 is provided at the end of the steel pipe. The steel pipe 4 abuts against the side of the support rod through the sealing end steel plate 41 to achieve sliding fit with the support rod. A cable rack roller 5 is sleeved on the steel pipe 4, and the cable rack roller 5 can slide on the steel pipe.

[0034] As Figure 1 and Figure 2 shown, in order to form a frame structure, four support columns 3 are located at the four corners. The four support columns 3 are connected by support rods to form a rectangle. Among them, the support rods have two lengths, namely the first support rod 1 and the second support rod 2. The first support rod 1 is longitudinally arranged in the Figure 1 viewing direction, and the second support rod 2 is transversely arranged in the Figure 1 . The length of the first support rod 1 is greater than the length of the second support rod 2.

[0035] As Figure 2 shown, the support column 3 is perpendicular to the support rod, and the ends of the support column 3 and the support rod are welded. Among them, in order to improve the bearing capacity of the pipeline, the support column can be connected with multiple layers of support rods along the height direction. Each layer of support rods is on the same plane. According to Figure 2 , it can be obtained that this embodiment is provided with two layers of support rods.

[0036] As Figure 1 shown, in order to further improve the bearing capacity of the pipeline, at least two columns of steel pipes 4 are arranged in each layer, and several steel pipes 4 in each column are arranged in parallel. In the Figure 1 of this embodiment, two columns of steel pipes 4 are arranged in each layer.

[0037] When two columns of steel pipes 4 are arranged, the two middle support columns can be shared, and the two middle support columns are connected by the first support rod 1 on both sides. Therefore, in this embodiment, when two layers of steel pipes are arranged and two columns of steel pipes are arranged in each layer, six support columns need to be arranged. Due to the two middle support columns, two first support rods 1 are required for each layer. Therefore, eight first support rods 1 need to be arranged, and eight second support rods 2 need to be arranged correspondingly. Or, when the length of the second support rod 2 is twice the length of the steel pipe, at this time, the end of the second support rod 2 is not welded to the support column in the middle position, and the middle position of the second support rod is welded to the support column.

[0038] It is understandable that the support column is made of H-shaped steel and the support rod is made of angle steel. The angle steel used in the first support rod is different from the angle steel used in the second support rod. The first support rod serves as the long side of the structure and the second support rod serves as the wide side of the structure.

[0039] In order to hoist the structure on the top of the pipe gallery, Figure 2 As shown, the top of the support column is higher than the support rod by a set distance, and the top of the support column is used for welding with the embedded steel plate 31. Figure 6 As shown, when constructing the pipe gallery, it is necessary to set an embedded steel plate 31 at the top of the pipe gallery. The embedded steel plate is embedded in the top position of the pipe gallery through steel bars, and then the top of the support column in the lifting structure of this embodiment is welded to the embedded steel plate 31 at the corresponding position to fix the lifting structure.

[0040] During on-site construction, the embedded steel plate 31 should be constructed in advance during the concrete pouring stage. At the same time, the hoisting structure should be located at the center of the top plate of the communication warehouse and should not be too close to the side wall to avoid affecting the pipeline passing through the outlet.

[0041] In a preferred example, the support column can be connected to a multi-layer support rod structure along the axial direction, so that the multi-layer steel pipe can be arranged on the first support rod 1 of the corresponding layer, thereby improving the bearing capacity of the pipeline.

[0042] In this embodiment, both ends of the first support rod 1 and the second support rod 2 are connected to the support columns and are vertically arranged, so the length of the second support rod needs to be adapted to the length of the steel pipe.

[0043] like Figure 1 As shown, the two sides of the two support columns at the middle position of each layer are connected by two first support rods 1.

[0044] In this embodiment, a row of steel pipes in a layer is taken as an example for description, which includes four parallel steel pipes, and end-sealing steel plates 41 are welded on both ends of the steel pipes. Figure 3 and Figure 4 The steel pipe is vertically overlapped on the two first support rods 1, and the end-sealing steel plates 41 at both ends abut against the opposite sides of the two first support rods 1, thereby enabling the steel pipe to slide on the first support rods 1, thereby adjusting the support position.

[0045] In order to prevent the pipeline from being damaged by friction due to pulling the pipeline during laying, in this embodiment, at least two sets of cable rack rollers are mounted on each steel pipe 4, wherein the cable rack roller 5 is a sleeve structure, which is sleeved on the steel pipe and can rotate axially on the steel pipe. The middle position of the outer side surface of the cable rack roller 5 serves as an annular groove for accommodating the pipeline, and end ring plates are formed at both ends to limit the pipeline and prevent the pipeline from escaping from the annular groove.

[0046] When actually laying pipelines, place the pipelines at the annular groove. When pulling the pipelines, through the rotational cooperation between the cable rack roller 5 and the steel pipe 4, it can be ensured that the pipelines will not be damaged by friction. By sliding the cable rack roller on the steel pipe, the laying position can be changed.

[0047] In the structure disclosed in this embodiment, by sliding the steel pipe along the first support rod, the longitudinal position of the cable rack roller can be changed. By sliding the cable rack roller along the steel pipe, the transverse position of the cable rack roller can be changed. Through the rotational cooperation between the cable rack roller and the steel pipe, it can be ensured that the pipelines will not be damaged by friction. During the process of laying and towing the pipelines, the structure can complete the rapid laying of cables by changing different support positions, with strong flexibility.

[0048] In an alternative example, as Figure 7 shown, in order to fix the position of the steel pipe after laying, fixing holes are evenly arranged on the angle steel, and a fixing piece 6 is fixed at the end of the steel pipe. The fixing piece 6 passes through the fixing holes to fix the position of the steel pipe. The fixing piece 6 can be selected as a connecting rope, which is fixed on the steel pipe. When adjusting the position of the steel pipe, as the position of the steel pipe moves, after adjustment, the end of the connecting rope passes through the fixing holes on the first support rod 1 and is tied and fixed.

[0049] Precautions: The welding work of the hoisting structure in this embodiment should be carried out in the pipe gallery. The environmental humidity should not be less than 80%, and the temperature should not be lower than 5°C. The main members should be welded within 24 hours after assembly. If it exceeds the time limit, cleaning or dehumidification treatment should be carried out at the welding part according to different situations before welding.

[0050] The welding flux and electrodes must be dried and used according to the product instructions. The dirt in the welding flux and the oil rust on the welding wire must be completely removed. Before welding, the harmful substances in the welding area must be thoroughly removed. When welding, it is strictly prohibited to strike an arc at the non-welding part of the base material. After welding, the molten slag on the surface of the weld and the spatter on both sides should be cleaned in time.

[0051] Mechanical properties of the steel plate welded joint: The results of the tensile test of the welded joint (yield strength, tensile strength, and elongation of the tensile bar) are not lower than the standard value of the base material, and the yield strength of the butt weld is not higher than 100 MPa of the actual strength of the base material; the fillet weld is not higher than 120 MPa of the actual strength of the base material. In order to control the welding deformation, sufficient shrinkage allowance for welding should be left for the welded plates, and the input of the line energy should be strictly controlled. During the welding operation, the workpiece should be turned over multiple times to avoid overhead welding operation as much as possible.

[0052] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
