Description

Technical Field

[0001] The invention belongs to the technical field of cable laying, and relates to a guide wiring laying device, in particular to a guide wiring laying device for power pipelines in urban tunnels. Background Art

[0002] Urban power grid refers to the power system that provides electricity supply to the city, which includes four links: power generation, transmission, distribution and consumption. Power generation is the starting point of the urban power grid. Power plants convert coal, natural gas, hydropower, nuclear energy and other energy into electrical energy. Power plants are flexibly adjusted according to the city's electricity demand and energy supply. The transmission link is to boost the high-voltage electricity generated by the power plant through a transformer, and then transmit it to various parts of the city through high-voltage transmission lines. Transmission lines are erected with high-voltage cables or towers to reduce energy loss. In cities, underground tunnels are often used for laying cables.

[0003] Urban tunnel power pipelines are public tunnels built underground in cities for the centralized laying of municipal pipelines such as electricity, communications, radio and television, and water supply. They are an important carrier for building smart cities. Compared with traditional direct burial, the pipelines have a good operating environment in the tunnel corridor, which can effectively extend the service life of the pipelines. The installation, expansion, maintenance and replacement of pipelines can also be carried out in the tunnel corridor, which can effectively reduce the frequency of road pavement excavation. It also plays an important role in earthquake prevention and disaster reduction, improving urban safety resilience and comprehensive carrying capacity, and intensive and efficient use of land resources.

[0004] After searching, it is found that a Chinese patent document discloses a cable laying auxiliary device for urban power grid corridors [Application No.: CN202310105313.2; Publication No.: CN115967052A]. This cable laying auxiliary device includes a base, a winding roller and a conductor assembly, the base is fixedly mounted with a side plate, the side plate is rotatably mounted with a rotating shaft, the winding roller is mounted on the rotating shaft, at least two winding rollers are provided, and the diameters of the two winding rollers are different.

[0005] Although the cable laying auxiliary equipment disclosed in this patent can lead the cables on the winding roller to the pipe corridors at different locations, when laying power pipelines inside urban tunnels, it usually requires multiple workers to assist in laying and locate the power pipelines. The work efficiency is very low, and due to the limited space inside urban tunnels, the operation is very inconvenient, which seriously affects the construction progress of urban tunnel power pipelines.

[0014] The working principle of the present invention is as follows: the cover plate is disassembled on one side of the top frame through the installation groove, a wall nail is installed between the fixed plate and the support frame, and under the action of the telescopic spring arranged on the other side of the support frame, the support frame fits the wall nail on one side of the fixed plate.

When the half gear plate meshes with the rack and is pushed out, the first return spring and the second return spring are stretched, so that the firing rod drives the nail pusher head away from the wall nail.

Under the action of the guide cylinder 34 being rotatably connected to the outer wall of the fixing rod 33, the guide cylinder 34 can guide the power pipeline at the upper and lower ends, so that the plurality of guide cylinders 34 can correct the deviation of the power pipeline between the two sets of guide components. Specifically, the side frame 35 is fixedly connected to the side frame 35. The rear end of the top frame 5 is symmetrically arranged in an "L" shape. Under the action of the side frame 35 and the guide cylinder 34, the multiple guide cylinders 34 guide the power pipeline between the two groups of guide units, ensuring the flatness of the power pipeline during the laying. At the same time, in order to improve the connection effect between the device and the side wall of the urban tunnel when moving, multiple moving cylinders 36 are rotatably connected to the inner side of the side frame 35, and the multiple moving cylinders 36 are equidistantly arranged. Through such an arrangement, when the device moves during the wiring, the moving cylinders 36 move synchronously on the surface of the wall side, and the structure is simple and the stability is high.

[0059] The working principle of the present invention is as follows: when in use, the cover plate 8 is disassembled on one side of the top frame 5 through the installation groove 40, and a wall nail is installed between the fixed plate 42 and the bracket 7. Under the action of the telescopic spring 6 set on the other side of the bracket 7, the bracket 7 makes the wall nail fit on one side of the fixed plate 42. After the wall nail is installed, the cover plate 8 is installed inside the top frame 5 through the installation groove 40, the wall nail is limited, and the push nail head 9 is set inside the through hole 37, and the power pipeline is set between the two groups of guide units to facilitate the transmission of the power pipeline through the guide unit. At the same time, the telescopic rod 4 is energized, the top frame 5 rises and moves to the top of the urban tunnel, and a side frame 35 is set on one side of the top frame 5, and a movable cylinder 3 is rotatably set inside the side frame 35. 6, the moving cylinder 36 is fitted with the side wall of the urban tunnel, which is convenient for the user to move the device through the handrail 3, so that the device can be moved and wired inside the urban tunnel through the moving wheel 2 and the moving cylinder 36. During the movement of the device, the dual-axis motor 23 is energized to rotate the third bevel gear 24, and under the meshing action of the third bevel gear 24 and the fourth bevel gear 25, the transmission rod 26 is rotated synchronously, and the transmission rod 26 is connected to the guide unit on one side, so that the rotating rod 29 is rotated, and the guide wheel 32 is fixedly connected to the outer wall of the rotating rod 29, so that the guide wheel 32 is rotated synchronously to guide the power pipeline, and the upper gear plate 28 and the lower gear plate 27 are fixedly connected to the outer walls of the upper and lower rotating rods 29. At the same time, by arranging the first synchronous wheel and the first synchronous belt 30 between the two groups of guide units, the guide units on both sides can synchronously convey the power pipeline, thereby ensuring the synchronization and consistency of the power pipeline transportation. Moreover, by arranging the guide cylinder 34 on one side of the guide wheel 32, under the action of the guide cylinder 34 rotatingly connected to the outer wall of the fixing rod 33, the plurality of guide cylinders 34 can guide the power pipeline between the two groups of guide units, thereby ensuring the flatness of the power pipeline during the laying. In the laying of the power pipeline guide, in order to achieve the positioning effect of the power pipeline inside the urban tunnel, a dual-axis motor is used. 23 drives the first bevel gear 19 to rotate. Under the meshing action of the first bevel gear 19 and the second bevel gear 20, the movable rod 18 drives the half gear plate 17 to rotate, so that the half gear plate 17 intermittently meshes with the rack 16. When the half gear plate 17 meshes with the rack 16 and pushes out, the first return spring 11 and the second return spring 13 are stretched, so that the firing rod 10 drives the push nail head 9 away from the wall nail. When the half gear plate 17 is not meshed with the rack 16, the first return spring 11 and the second return spring 13 drive the firing rod 10 to reset under the elastic action, so that the firing rod 10 drives the push nail head 9 to hit the wall nail, so that the wall nail is knocked out of the top frame 5 by the push nail head 9 to fix the side wall of the urban tunnel, thereby positioning and fixing the power pipeline.The device can accurately locate the power pipeline simultaneously during the guiding and wiring process, and has a simple structure and strong practicality. This completes the working principle of the guiding and wiring laying device for the power pipeline in the urban tunnel.

[0060] In summary, in the present invention, by telescopically setting the top frame 5 on the top of the base 1, the device can guide the wiring of the power pipeline at different heights inside the urban tunnel, and by setting the support frame 7 inside the top frame 5, the support frame 7 is always pressed against the wall nail on one side, ensuring the installation effect of the wall nail on one side of the fixed plate 42, and by telescopically setting the firing rod 10 and the nail pusher head 9 inside the fixed box 41, the firing rod 10 and the nail pusher head 9 can be intermittently fired under the action of the dual-axis motor 23, which is convenient for the interval positioning and fixing of the power pipeline, realizing efficient guiding wiring of the power pipeline in the urban tunnel, and performing integrated positioning and fixing, and simple operation. Compared with the existing urban tunnel power pipeline, it greatly saves labor costs and is conducive to improving construction efficiency, solving the technical problem that the current guiding wiring laying device cannot quickly and accurately guide wiring auxiliary laying of the power pipeline inside the urban tunnel.
