Description

Technical Field

[0001] The present invention belongs to the technical field of subway construction, and specifically relates to a fixing device for subway pipeline construction. Background Art

[0002] The subway is a form of railway transportation, referring to an urban rail transit system mainly operating underground, which is a rapid, large-capacity, and electrically powered rail transit built in the city. The train runs on a fully enclosed line. The lines in the central urban area are basically located in underground tunnels, and the lines outside the central urban area are generally located on viaducts or on the ground. The subway construction process has a long cycle and is complex. During the construction process, various pipelines need to be fixed to avoid pipeline chaos and movement.

[0003] The fixing device for subway pipelines is generally fixed on the wall or other equipment. To ensure that the construction and installation of pipelines meet the requirements, pipelines need to be placed at different heights at different installation positions. Therefore, the fixing hanger is generally set to be adjustable. Fixed holes are provided on the surface of the hanger, and bolts can be used to adjust the height of the bottom support plate of the hanger according to needs, so that the supported pipeline is at the required height. However, after the hanger is installed and the pipeline is laid, because the pipeline is heavy, it is very troublesome to adjust the height of the pipeline later. Auxiliary tools for temporarily supporting the pipeline are required and multiple people need to cooperate, and the adjustment accuracy is low. Summary of the Invention

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] Such as Figures 1 to 6As shown in the figure, an embodiment of the present invention provides a fixing device for subway pipeline construction, which includes two fixed square pipes 1. At the bottom inside the fixed square pipe 1, a movable square pipe 101 is installed. At the bottom of the movable square pipe 101, a support plate 102 is fixedly connected. At the top inside the fixed square pipe 1, a rotating rod 2 is movably sleeved. On the right side of the rotating rod 2, a handle 201 is fixedly connected. At the top inside the fixed square pipe 1, a fixed block 12 is fixedly connected. At the bottom of the fixed block 12, a threaded rod 13 is movably sleeved. At the top of the threaded rod 13, a driven bevel gear 14 is fixedly connected. On the outer side of the rotating rod 2, a driving bevel gear 202 is fixedly sleeved. The driving bevel gear 202 meshes with the driven bevel gear 14. At the top inside the movable square pipe 101, a threaded block 112 is fixedly connected. The threaded block 112 is threadedly sleeved with the threaded rod 13. On the outer side of the support plate 102, an adjusting assembly 3 is installed. On the top of the adjusting assembly 3, a fixing assembly 4 is installed.

[0027] In the embodiment of the present application, when it is necessary to adjust the height of the support plate 102, the rotating rod 2 is rotated through the handle 201, so as to drive the two threaded rods 13 to rotate synchronously and in the same direction through the meshing action of the driving bevel gear 202 and the driven bevel gear 14. Under the threaded thrust of the threaded rod 13, the threaded block 112 moves synchronously up and down along the outer side of the threaded rod 13, and then the movable square pipe 101 drives the support plate 102 to rise and fall, finally realizing the adjustment of the height of the support plate 102, and the height of the pipeline can be adjusted according to the actual construction fixing needs of the pipeline. And through the setting of the first scale 111, the height of the second scale 121 from the mounting plate 103 can be accurately judged.

[0028] Among them, at the top of the fixed square pipe 1, a mounting plate 103 is fixedly connected. On the surface of the mounting plate 103, a bolt hole 131 is opened.

[0029] Use an expansion bolt to pass through the bolt hole 131 to fix the mounting plate 103 at the required position.

[0030] Among them, in the middle of the inner sides of the two fixed square pipes 1, a fixing rod 11 is fixedly connected. On the front surface of the movable square pipe 101, a first scale 111 is provided.

[0031] The setting of the fixing rod 11 can enhance the overall stability of the device, keep the two fixed square pipes 1 always in a parallel state, and prevent the device from deforming.

[0032] Among them, on both sides of the inner wall of the fixed square pipe 1, a first roller 15 is movably sleeved. The first roller 15 is in contact with the side surface of the movable square pipe 101. Through the first scale 111, the distance between the pipeline and the top of the building can be judged.

[0033] Among them, the adjusting component 3 includes a sliding frame 301 slidably sleeved outside the support plate 102. A support block 302 is fixedly connected to the front of the bottom of the sliding frame 301. A movable rod 303 is movably sleeved on the front of the support block 302. A fixed ring 304 is fixedly connected to the front of the movable rod 303. A toothed plate 305 is fixedly connected to the back of the movable rod 303. A pressure spring 306 is movably sleeved outside the movable rod 303. The pressure spring 306 is located between the support block 302 and the toothed plate 305. A fixing plate 104 is fixedly connected to the bottom of the support plate 102. A tooth 141 is fixedly connected to the front of the fixing plate 104. The tooth 141 meshes with the toothed plate 305.

[0034] When the position of the adjusting component 3 needs to be adjusted, pull the fixed ring 304 forward to separate the toothed plate 305 from the tooth 141, and then the sliding frame 301 can be horizontally moved along the outside of the support plate 102. The position of the adjusting component 3 can be judged through the second scale 121. After moving to the required position, release the fixed ring 304. The pressure spring 306 has a thrust force on the toothed plate 305 towards the back, so that the toothed plate 305 and the tooth 141 are engaged, and then the position of the adjusting component 3 is fixed. By adjusting the position of the pipeline, the situation of pipeline accumulation is avoided, the support plate 102 is evenly stressed, and it is convenient for later maintenance.

[0035] Among them, second rollers 311 are movably sleeved on the front and back inner walls of the sliding frame 301. The second rollers 311 are in contact with the surface of the support plate 102.

[0036] When the position of the adjusting component 3 is horizontally adjusted, the second rollers 311 roll on the surface of the support plate 102, avoiding jamming when the adjusting component 3 moves.

[0037] Among them, the fixing component 4 includes a support plate 401 fixedly connected to the top of the sliding frame 301. A fixing frame 402 is fixedly connected to the top of the support plate 401.

[0038] The fixing frame 402 plays a role in positioning the pipeline, avoiding horizontal deviation.

[0039] Among them, a second scale 121 is provided on the front of the support plate 102. The vertical section of the movable rod 303 is elliptical.

[0040] The shape design of the movable rod 303 prevents the movable rod 303 from rotating, and it can only move horizontally in the front and back directions, thus preventing the toothed plate 305 from rotating and shifting, and enabling the toothed plate 305 to stably mesh with the tooth 141.

[0041] Working principle and usage process:

[0042] When it is necessary to adjust the height of the support plate 102, the rotating rod 2 is rotated by the handle 201, so that the two threaded rods 13 are driven to rotate synchronously and in the same direction through the meshing of the driving bevel gear 202 and the driven bevel gear 14. Under the action of the thread thrust of the threaded rod 13, the threaded blocks 112 move synchronously up and down along the outside of the threaded rod 13, and then the movable square tube 101 drives the support plate 102 to move up and down, finally realizing the adjustment of the height of the support plate 102, and the height of the pipeline can be adjusted according to the actual construction fixing needs of the pipeline. And through the setting of the first scale 111, the height of the second scale 121 from the mounting plate 103 can be accurately judged;

[0043] When it is necessary to adjust the position of the adjusting assembly 3, the fixing ring 304 is pulled forward to separate the toothed plate 305 from the teeth 141, and then the sliding frame 301 can be moved horizontally along the outside of the support plate 102. The position of the adjusting assembly 3 can be judged through the second scale 121. After moving to the required position, the fixing ring 304 is released. The compression spring 306 has a thrust on the toothed plate 305 towards the back, so that the toothed plate 305 and the teeth 141 are engaged, and then the position of the adjusting assembly 3 is fixed. By adjusting the position of the pipeline, the situation of pipeline accumulation is avoided, the support plate 102 is evenly stressed, and it is convenient for later maintenance.
