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] The urban power grid refers to the power system that provides electricity to the city. It 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 electricity. 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 transformers, and then transmit it to various parts of the city through high-voltage transmission lines. The 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] A search revealed a Chinese patent document that discloses a cable laying auxiliary device for urban power grid corridors [Application Number: CN202310105313.2; Publication Number: 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, which is rotatably mounted with a rotating shaft. The winding roller is mounted on the rotating shaft. There are at least two winding rollers, each with different diameters.

[0005] Although the cable laying auxiliary equipment disclosed in this patent can lead the cables on the winding roller to the pipeline 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. Moreover, due to the limited space inside urban tunnels, the operation is very inconvenient, which seriously affects the construction progress of urban tunnel power pipelines. Summary of the Invention

The technical problem to be solved by this invention is: how to conveniently guide the wiring and assist in the positioning and laying of power pipelines inside urban tunnels.

[0007] The purpose of the present invention can be achieved through the following technical solutions:

[0011] The outer wall of the fixed box is fixedly connected to a second return spring, and the second return spring is sleeved and connected to the outer wall of the firing rod. The end of the second return spring away from the fixed box is fixedly connected to a limit plate, and the limit plate is fixedly connected to the end of the firing rod away from the nail pushing head;

[0012] The bottom end of the fixing ring is fixedly connected to a connecting rod, and the bottom end of the connecting rod is fixedly installed with a rack, the outer side of the rack is transmission-connected to a synchronous drive assembly, and the other end of the synchronous drive assembly is also transmission-connected to a guide assembly;

[0013] The guide assembly includes two groups of guide units respectively arranged at both ends of the top frame, one group of guide units is connected to a dual-axis motor for transmission, the guide unit includes four guide wheels, and the four guide wheels are arranged in pairs and parallel to each other. The inside of the four guide wheels is fixedly connected to a rotating rod, and the rotating rod is rotatably connected to both sides of the top frame, and the rotating rod below one group of guide units is fixedly connected to a transmission rod.

[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, and the wall nail is installed between the fixed plate and the retaining frame. Under the action of the telescopic spring arranged on the other side of the retaining frame, the retaining frame fits the wall nail on one side of the fixed plate. After the wall nail is installed, the cover plate is installed inside the top frame through the installation groove, the wall nail is limited, and the push nail head is arranged inside the through hole, and the power pipeline is arranged 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 is energized, and the top frame rises and moves to the top of the urban tunnel. Moreover, a side frame is arranged on one side of the top frame, and under the action of the movable cylinder arranged to rotate inside the side frame, The moving cylinder is fitted with the side wall of the urban tunnel, which is convenient for the user to move the device through the handrail, so that the device can be moved and laid inside the urban tunnel through the moving wheel and the moving cylinder. During the movement of the device, the dual-axis motor is energized to rotate the third bevel gear, and under the meshing action of the third bevel gear and the fourth bevel gear, the transmission rod is rotated synchronously. The transmission rod is connected to the guide unit on one side, so that the rotating rod is rotated. By fixing the guide wheel on the outer wall of the rotating rod, the guide wheel is rotated synchronously to guide the power pipeline, and under the action of the upper gear plate and the lower gear plate fixedly connected to the outer walls of the upper and lower rotating rods, the upper and lower guide wheels are moved in opposite directions. The rotation is convenient for driving the power pipeline for transportation, which is beneficial to improving the wiring efficiency of the power pipeline. At the same time, by arranging the first synchronous wheel and the first synchronous belt between the two sets of guide units, the guide units on both sides can synchronously transport the power pipeline, ensuring the synchronization and consistency of the power pipeline transportation, and by arranging a guide cylinder on one side of the guide wheel, under the action of the guide cylinder rotating connection on the outer wall of the fixed rod, multiple guide cylinders can guide the power pipeline between the two sets of guide units, ensuring the flatness of the power pipeline during wiring and laying. In the guided laying of the power pipeline, in order to achieve the positioning effect of the power pipeline inside the urban tunnel, the first cone is driven by the dual-axis motor When the gear rotates, the movable rod drives the half gear plate to rotate under the meshing action of the first bevel gear and the second bevel gear, so that the half gear plate intermittently meshes with the rack. When the half gear plate engages 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. When the half gear plate is not engaged with the rack, the first return spring and the second return spring drive the firing rod to reset under the elastic action, so that the firing rod drives the nail pusher head to hit the wall nail, so that the wall nail is knocked out of the top frame and fixed to the side wall of the urban tunnel, thereby positioning and fixing the power pipeline, realizing that the device can simultaneously accurately position the power pipeline during guiding wiring.

[0015] The synchronous drive assembly includes a mounting frame, and the mounting frame is fixedly mounted on the bottom end of the top frame, a dual-axis motor is fixedly connected to the surface of the mounting frame, and one output end of the dual-axis motor is fixedly connected to a cross bar, and the output shaft of the dual-axis motor away from the cross bar is fixedly connected to the third bevel gear;

[0022] The two sets of guide units are connected by a transmission unit, and the transmission unit includes a first synchronous belt. The inner walls of both ends of the first synchronous belt are meshed with first synchronous wheels, and the two first synchronous wheels are respectively fixedly connected to the outer walls of the rotating rods above the two sets of guide units.

[0023] By adopting the above structure, the guide units on both sides of the top frame can be transmitted, making it convenient for a single set of motors to synchronously drive the guide units on both sides for transmission, and realizing the guidance synchronization and consistency of the guide units on both sides of the top frame, facilitating the precise and synchronous guided transportation of the power pipelines.

[0025] The outer walls of the two parallel rotating rods below are both fixedly connected with the second synchronous wheels, and the outer walls of the two second synchronous wheels are meshedly connected with the second synchronous belt.

[0026] By adopting the above structure, the upper and lower guide wheels are arranged to rotate in opposite directions through the meshing setting of the upper gear plate and the lower gear plate. Through such a setting, the upper and lower guide wheels can guide the power pipeline through synchronous rotation, which is beneficial to improving the transmission efficiency of the power pipeline.

[0031] The outer wall of the support frame is fixedly connected with a slider, and the outer wall of the slider is slidably connected with a slideway, and the slideway is opened on the inner wall of the top frame.

[0032] With the above structure, by setting the slider and the slideway, the moving path of the support frame on the inner wall of the top frame is stable, which makes it easy for the support frame to accurately press the wall nail inside the top frame, ensuring the accuracy of the wall nail position.

[0033] The inner wall of the top frame is provided with a mounting groove for accommodating the insertion of the cover plate, and the interior of the cover plate is provided with a through hole for accommodating the movement of the firing rod.

In order to achieve stable driving of the rack 16, a synchronous drive assembly is transmission-connected to the outer side of the rack 16, and the other end of the synchronous drive assembly is also transmission-connected to the guide assembly.

[0055] Furthermore, the synchronous drive assembly includes a mounting bracket 22, which is arranged in an "L"-shaped structure, and the mounting bracket 22 is fixedly mounted on the bottom end of the top frame 5, and the surface of the mounting bracket 22 is fixedly connected to the double-axis motor 23. Under the fixing action of the mounting bracket 22 and the top frame 5, the top frame 5 can be driven by the mounting bracket 22 to move the double-axis motor 23 up and down synchronously. At the same time, in order to achieve stable driving of the double-axis motor 23, a cross bar 21 is fixedly connected to the output end of one end of the double-axis motor 23, and the output shaft of the double-axis motor 23 away from one end of the cross bar 21 is fixedly connected to the third bevel gear 24, and the end of the cross bar 21 away from the double-axis motor 23 is fixedly connected to the second bevel gear 20.

The upper gear plate 28 and the lower gear plate 27 are meshed with each other. Through the meshing setting of the upper gear plate 28 and the lower gear plate 27, the upper and lower guide wheels 32 are arranged to rotate in opposite directions. Through such a setting, the upper and lower guide wheels 32 can guide the power pipeline through synchronous rotation, which is beneficial to improving the transmission efficiency of the power pipeline. At the same time, in order to achieve the synchronous transmission effect of the guide wheels 32 in a single group of guide units, the outer walls of the two parallel rotating rods 29 below are fixedly connected to the second synchronous wheels, and the outer walls of the two second synchronous wheels are meshed with the second synchronous belt 31. Through such a setting, the two guide wheels 32 arranged in parallel on the left and right rotate synchronously, ensuring the guiding and transmission effect of the single group of guide units on the power pipeline.

[0057] Furthermore, in order to realize the transmission between the two groups of guide units on both sides of the top frame 5, a transmission unit is passed between the two groups of guide units, wherein the transmission unit includes a first synchronous belt 30, and the inner walls of both ends of the first synchronous belt 30 are meshed and connected with first synchronous wheels, and the two first synchronous wheels are respectively fixedly connected to the outer walls of the rotating rod 29 above the two groups of guide units.

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 frames 35 and the guide cylinders 34, multiple guide cylinders 34 guide the power pipeline between the two sets of guide units, ensuring the flatness of the power pipeline during routing. At the same time, to ensure the connection between the device and the side wall of the urban tunnel during movement, multiple moving cylinders 36 are rotatably connected to the inner side of the side frames 35, and the multiple moving cylinders 36 are arranged at equal distances. With this arrangement, when the device moves during routing, the moving cylinders 36 move synchronously with the surface of the wall, and the structure is simple and stable.

[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 the 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. 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, and the top frame 5 rises and moves to the top of the urban tunnel. In addition, by setting a side frame 35 on one side of the top frame 5, the movable cylinder 3 is rotated 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 inside the urban tunnel through the moving wheel 2 and the moving cylinder 36 for wiring. During the movement of the device, the dual-axis motor 23 is energized, so that the third bevel gear 24 rotates. Under the meshing action of the third bevel gear 24 and the fourth bevel gear 25, the transmission rod 26 rotates synchronously, and the transmission rod 26 is connected to the guide unit on one side, so that the rotating rod 29 rotates. By fixing the guide wheel 32 on the outer wall of the rotating rod 29, the guide wheel 32 rotates 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 sets 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, the guide cylinder 34 is connected to the outer wall of the fixed rod 33 through rotation, thereby guiding the power pipeline between the two sets of guide units, thereby ensuring the flatness of the power pipeline during wiring and 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 is pushed out, the first return spring 11 and the second return spring 13 are stretched, so that the firing rod 10 drives the nail pushing 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 nail pushing head 9 to hit the wall nail, so that the wall nail is knocked out of the top frame 5 by the nail pushing 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 urban tunnel power pipelines.

[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 power pipelines 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 the side of the fixed plate 42, and by telescopically setting the firing rod 10 and the pushing nail head 9 inside the fixed box 41, the firing rod 10 and the pushing nail head 9 can be intermittently fired under the action of the dual-axis motor 23, which is convenient for the spaced 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, which is simple to operate. Compared with the existing urban tunnel power pipelines, 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 power pipelines inside urban tunnels.
