Technical Field
[0001] This utility model belongs to the technical field of equipment for underground utility tunnels, and in particular relates to an adjustable support for underground utility tunnels. Background Technology
[0002] Underground utility tunnels are centralized pipeline tunnels built underground in cities, which centrally lay various municipal pipelines such as electricity, communication, water supply and drainage, and gas. They can avoid repeated road excavation, reduce pipeline maintenance costs, reduce safety hazards, save underground space, beautify the urban environment, and serve as underground lifelines to ensure the normal operation of cities.
[0003] Existing support structures have several drawbacks, such as: their length cannot be adjusted, they can only accommodate a fixed number of cables, which wastes space when the number of cables is less than the fixed capacity, and cannot accommodate more than the fixed capacity, leading to clutter and making them only suitable for fixed scenarios. Therefore, we propose an adjustable support structure for underground utility tunnels. Utility Model Content
[0004] The purpose of this invention is to provide an adjustable support for underground utility tunnels to solve the problems mentioned in the background art.
[0005] In view of this, the present invention provides an adjustable support for underground utility tunnels, including a base, and further comprising: A fixed rod is fixedly installed on the top of the base. An extension rod is inserted into the top of the fixed rod. Both the fixed rod and the extension rod have a power cavity. A rotating disk is rotatably installed in each of the two power cavities. Several limiting grooves are provided on the extension rod. The rotating disk is inserted into the limiting grooves. Two fixing bars are respectively fixedly installed on the fixing rod and the extension rod. A rotating column is rotatably installed inside each of the two fixing bars, and a rotating rod is fixedly installed at one end of each of the two rotating columns. Two sets of drive components are located within two fixed bars and are used to drive the two rotating disks to rotate. Two sets of fixing components are located on the fixing rod and the extension rod, respectively, and are used to fix the positions of the two rotating columns.
[0006] In this technical solution, when a large number of cables need to be placed horizontally, the worker can rotate the rotating rod and drive the rotating column to rotate by the fixed component. After the rotating column rotates 180°, the fixed component can fix the position of the rotating column and the rotating rod. The rotating rod can extend the placement space of the fixed strip, and more cables can be placed horizontally. When a large number of cables need to be placed vertically, the drive assembly can rotate the rotating disk. Then, the extension rod is inserted into the fixed rod. When the extension rod is inserted to the appropriate height, the drive assembly rotates the rotating disk and resets it. The rotating disk is inserted into the limit groove, which can fix the position of the extension rod and the fixed rod. More cables can be placed vertically, and the spacing between the cables in the vertical direction can be adjusted according to the requirements.
[0007] In the above technical solution, the driving component further includes: The first bevel gear is rotatably mounted inside the power chamber. The upper end of the first bevel gear is fixedly connected to the rotating disk. A torsion spring is sleeved on the first bevel gear. The two ends of the torsion spring are fixedly connected to the rotating disk and the inner wall of the power chamber, respectively. A second bevel gear is meshed on one side of the first bevel gear.
[0008] In this technical solution, when a large number of cables need to be placed vertically, the second bevel gear is first rotated forward. The second bevel gear drives the first bevel gear meshing with it to rotate, and the first bevel gear drives the rotating disk to rotate. At the same time, the torsion spring is twisted. Then, the extension rod is inserted into the fixed rod. When the extension rod is inserted to a suitable height, the second bevel gear is released. Under the action of the torsion force of the torsion spring, the rotating disk rotates and resets. The rotating disk is inserted into the limiting groove, which can fix the position of the extension rod and the fixed rod. More cables can be placed vertically, and the cable spacing in the vertical direction can be adjusted according to requirements.
[0009] In the above technical solution, the fixing component further includes: A sliding groove is formed within a fixed strip. A limiting plate is slidably installed within the sliding groove. Two guide posts are fixedly installed on one side of the limiting plate, and springs are sleeved on both guide posts. A rotating post passes through the other side of the limiting plate, and the limiting plate and the rotating post are inserted into each other.
[0010] In this technical solution, when a large number of cables need to be placed horizontally, the limiting plate is first pulled to slide. The limiting plate drives the two guide posts to slide, and at the same time, the two springs are compressed and contracted. After the limiting plate disengages from the rotating post, the rotating rod can be rotated to drive the rotating post to rotate. After the rotating post rotates 180°, the limiting plate is released. Under the action of the rebound force of the two springs, the limiting plate and the two guide posts slide towards the rotating post. Finally, the limiting plate is inserted into the rotating post, which can fix the position of the rotating post and the rotating rod. The rotating rod can extend the placement space of the fixing strip, and more cables can be placed horizontally.
[0011] In the above technical solution, further, several of the limiting grooves are distributed at equal intervals on the extension rod.
[0012] In this technical solution, the extension rod can be fixed at any position on the fixed rod, ensuring that the cable spacing in the vertical direction can be adjusted as needed.
[0013] In the above technical solution, the cross-section of the rotating disk is elliptical.
[0014] In this technical solution, the rotating disk is inserted into the limiting groove to fix the position of the extension rod and the fixed rod.
[0015] In the above technical solution, a handle is further fixedly installed at one end of the second bevel gear, and one end of the handle passes through the power cavity and extends to the outside.
[0016] In this technical solution, a handle is provided to facilitate the rotation of the second bevel gear by the operator.
[0017] In the above technical solution, furthermore, the two ends of the spring are welded to the inner wall of the sliding groove and the limiting plate, respectively.
[0018] In this technical solution, the spring is ensured to be used stably.
[0019] In the above technical solution, the guide post is slidably connected to the sliding groove, and the handle is rotatably connected to the power cavity.
[0020] In this technical solution, the guide column can slide stably within the sliding groove, ensuring that the handle can rotate stably within the power chamber.
[0021] The beneficial effects of this utility model are: 1. The underground utility tunnel uses adjustable supports. When a large number of cables need to be placed horizontally, the workers can rotate the rotating rod and drive the rotating column to rotate through the fixed components. After the rotating column rotates 180°, the fixed components can fix the position of the rotating column and the rotating rod. The rotating rod can extend the placement space of the fixing strip, and more cables can be placed horizontally.
[0022] 2. The underground utility tunnel uses adjustable supports. When a large number of cables need to be placed vertically, the drive assembly can rotate the rotating disk. Then, the extension rod is inserted into the fixed rod. When the extension rod is inserted to the appropriate height, the drive assembly rotates the rotating disk and resets it. The rotating disk is inserted into the limit groove, which can fix the position of the extension rod and the fixed rod. More cables can be placed vertically, and the spacing between the cables in the vertical direction can be adjusted according to requirements. Attached Figure Description

[0027] Example 1: This example provides an adjustable support for underground utility tunnels, including a base 1, and further comprising: Fixed rod 2 is fixedly installed on the top of base 1. An extension rod 3 is inserted into the top of fixed rod 2. Both fixed rod 2 and extension rod 3 have a power cavity 7. A rotating disk 11 is rotatably installed in both power cavities 7. Several limiting grooves 13 are opened on extension rod 3. The rotating disk 11 is inserted into the limiting groove 13. Two fixing bars 4 are fixedly installed on the fixing rod 2 and the extension rod 3 respectively. A rotating column 5 is rotatably installed inside each of the two fixing bars 4. A rotating rod 6 is fixedly installed at one end of each of the two rotating columns 5. Two sets of drive components are located in two fixed bars 4 respectively, and are used to drive the two rotating disks 11 to rotate. Two sets of fixing components are located on the fixing rod 2 and the extension rod 3 respectively, and are used to fix the positions of the two rotating columns 5.
[0028] When a large number of cables need to be placed horizontally, the fixed components allow the operator to rotate the rotating rod 6 and drive the rotating column 5 to rotate. After the rotating column 5 rotates 180°, the fixed components can fix the position of the rotating column 5 and the rotating rod 6. The rotating rod 6 can extend the placement space of the fixed strip 4, allowing more cables to be placed horizontally. When a large number of cables need to be placed vertically, the drive assembly can rotate the rotating disk 11. Then, the extension rod 3 is inserted into the fixed rod 2. When the extension rod 3 is inserted to a suitable height, the drive assembly rotates the rotating disk 11 and resets it. The rotating disk 11 is inserted into the limiting groove 13, which can fix the position of the extension rod 3 and the fixed rod 2. More cables can be placed vertically, and the cable spacing in the vertical direction can be adjusted according to requirements.
[0029] In this embodiment, the driving component includes: The first bevel gear 8 is rotatably installed in the power chamber 7.

The two ends of the torsion spring 12 are fixedly connected to the rotating disk 11 and the inner wall of the power chamber 7, respectively. A second bevel gear 9 is meshed on one side of the first bevel gear 8. When a large number of cables need to be placed vertically, the second bevel gear 9 is rotated forward first. The second bevel gear 9 drives the first bevel gear 8, which meshes with it, to rotate. The first bevel gear 8 drives the rotating disk 11 to rotate. At the same time, the torsion spring 12 is twisted. Then, the extension rod 3 is inserted into the fixed rod 2. When the extension rod 3 is inserted to a suitable height, the second bevel gear 9 is released. Under the torsional force of the torsion spring 12, the rotating disk 11 rotates and resets. The rotating disk 11 is inserted into the limiting groove 13, which can fix the position of the extension rod 3 and the fixed rod 2. More cables can be placed vertically, and the cable spacing in the vertical direction can be adjusted according to needs.

The other side of the limiting plate 15 passes through the rotating post 5, and the limiting plate 15 and the rotating post 5 are inserted into each other. When a large number of cables need to be placed horizontally, the limiting plate 15 is first pulled to slide. The limiting plate 15 drives the two guide posts 16 to slide, and at the same time, the two springs 17 are compressed and contracted. After the limiting plate 15 is disengaged from the rotating post 5, the rotating rod 6 can be rotated to drive the rotating post 5 to rotate. After the rotating post 5 rotates 180°, the limiting plate 15 is released. Under the action of the rebound force of the two springs 17, the limiting plate 15 and the two guide posts 16 slide towards the rotating post 5.
