Abstract
Description
Technical Field
[0001] This utility model relates to the field of channel device technology, and in particular to a combined subway tunnel pre-embedded channel. Background Technology
[0002] Pre-embedded channels in subway tunnels are channel-type embedded parts that are pre-installed in concrete structures during subway construction. They are mainly used to fix and support various equipment and pipelines, ensuring the safe operation of the subway system.
[0003] Pre-embedded channels are channels that are pre-installed in concrete. They are used to connect pipe supports, cable supports, etc. in the tunnel with T-bolts. In the current technology, the T-bolts and pre-embedded channels are fixed by tightening with nuts. However, after long-term use, they are prone to loosening, which reduces the stability of the device. Utility Model Content
[0004] To address the aforementioned problems, this utility model provides a combined subway tunnel pre-embedded channel.
[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a combined subway tunnel pre-embedded channel, including a channel plate, a channel is formed through the side wall of the channel plate, a pre-embedded channel is formed through the inner bottom wall of the channel, two mutually symmetrical pre-embedded rods are fixedly arranged on the upper surface of the channel plate, and limit rings are fixedly arranged on the outer walls of the two pre-embedded rods, a T-bolt is slidably arranged in the channel, the lower end of the T-bolt passes through the pre-embedded channel and extends below the channel plate, and a fixing component for fixing the T-bolt is provided in the channel.
[0006] By adopting the above technical solution, when using the pre-embedded channel, the workers face the channel downwards. Then, the pre-embedded rod and limiting ring are embedded in the concrete. At this point, the workers move the T-bolt into the channel, position it appropriately, and fix it in place using the fixing assembly. During this process, the fixing assembly reduces the probability of the T-bolt shaking during prolonged use, thereby improving the stability of the device.
[0007] Furthermore, multiple blocking grooves are provided on the two opposite inner walls of the channel, and fixing grooves are provided on the two opposite side walls of the T-bolt. A sliding groove is provided on the inner walls of the two fixing grooves. The fixing assembly includes a fixing block slidably disposed in the fixing groove and a sliding rod slidably disposed in the sliding groove. The fixing block is slidably connected to the blocking groove. A first inclined surface is provided on the edge where one of the adjacent side walls intersects on the side wall of the fixing block away from the blocking groove.
[0008] By adopting the above technical solution, when the worker needs to fix the T-bolt in the channel, the worker needs to slide the slide rod upward, so that the slide rod gradually approaches and finally presses against the first inclined surface, so that the fixing block slides under the action of the slide rod, and then one end of the fixing block slides into the blocking groove, so that the T-bolt is fixed in the channel under the action of the fixing block, thereby reducing the probability of the T-bolt shaking after long-term use, and thus improving the stability of the device.
[0009] Furthermore, a rotating groove is provided through the inner bottom wall of the slide, and an adjusting bolt is rotatably installed in the rotating groove. The adjusting bolt is threadedly connected to the slide rod.
[0010] By adopting the above technical solution, when the worker needs to slide the slide bar upward, the worker needs to turn the adjusting bolt, and then the slide bar slides upward under the action of the adjusting bolt. In this process, the difficulty of the worker sliding the slide bar is reduced, thereby reducing the difficulty of the worker's work.
[0011] Furthermore, a limiting groove is formed on the inner top wall of the fixing groove, and a limiting block is slidably arranged in the limiting groove, with the limiting block and the fixing block being fixed to each other.
[0012] By adopting the above technical solution, when the fixed block slides, the limiting block slides synchronously with the fixed block. During this process, the limiting block limits the fixed block, thereby reducing the probability of the fixed block and the fixed groove separating from each other, thus improving the stability of the device.
[0013] Furthermore, a reset spring is fixedly provided on the side wall of the limiting block, and the other end of the reset spring is fixedly provided on the inner wall of the limiting groove.
[0014] By adopting the above technical solution, when the sliding rod and the fixed block are separated from each other, the limiting block slides away from the blocking groove under the action of the return spring, thereby causing the fixed block to slide away from the blocking groove under the action of the limiting block, thus reducing the difficulty for the staff to reset the fixed block and thus reducing the difficulty of the staff's work.
[0015] Furthermore, a circular groove is formed on the inner wall of the rotating groove, and a circular block is rotatably arranged in the circular groove. The circular block is fixed to the adjusting bolt.
[0016] By adopting the above technical solution, when the adjusting bolt rotates, the circular block rotates under the action of the adjusting bolt. During this process, the circular block reduces the probability of the adjusting bolt moving up and down, thereby improving the stability of the device.
[0017] Furthermore, the bottom surface of the adjusting bolt is provided with a hexagonal groove, and the bottom surface of the adjusting bolt is flush with the bottom surface of the T-bolt.
[0018] By adopting the above technical solution, the hexagonal slot reduces the difficulty for workers to rotate the adjusting bolt, thereby reducing the difficulty of their work.
[0019] Furthermore, the channel plate is made of stainless steel.
[0020] By adopting the above technical solution, the stainless steel trough plate has improved corrosion resistance, thereby extending the service life of the device.
[0021] In summary, this utility model has the following beneficial effects:
[0022] 1. In this application, when using the pre-embedded channel, the worker places the pre-embedded channel downwards. Then, the pre-embedded rod and limiting ring are embedded in the concrete. At this point, the worker moves the T-bolt into the channel, moves the T-bolt to a suitable position, and fixes the T-bolt in the channel using the fixing component. During this process, the fixing component reduces the probability of the T-bolt shaking after prolonged use, thereby improving the stability of the device.
[0023] 2. In this application, when the worker needs to fix the T-bolt in the channel, the worker needs to slide the slide rod upward, so that the slide rod gradually approaches and finally presses against the first inclined surface, so that the fixing block slides under the action of the slide rod, and then one end of the fixing block slides into the blocking groove, so that the T-bolt is fixed in the channel under the action of the fixing block, thereby reducing the probability of the T-bolt shaking after long-term use, thereby improving the stability of the device;
[0024] 3. In this application, when the worker needs to slide the slide bar upward, the worker needs to turn the adjusting bolt, so that the slide bar slides upward under the action of the adjusting bolt. In this process, the difficulty of the worker sliding the slide bar is reduced, thereby reducing the difficulty of the worker's work. Attached Figure Description

[0029] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.
[0030] like Figure 1-3 As shown in the figure, this application discloses a combined subway tunnel pre-embedded channel, including a channel plate 1, pre-embedded rods 13, limiting rings 14, T-bolts 15, fixing components 3, adjusting bolts 4, limiting blocks 5, return springs 6, and circular blocks 7. A channel 11 is formed through the side wall of the channel plate 1, and a pre-embedded channel 12 is formed through the inner bottom wall of the channel 11. Two pre-embedded rods 13 are provided and symmetrically arranged on the upper surface of the channel plate 1, and the limiting rings 14 are fixedly arranged on the outer walls of the two pre-embedded rods 13. The T-bolts 15 are slidably arranged in the channel 11, and the lower ends of the T-bolts 15 pass through the pre-embedded channel 12 and extend below the channel plate 1.
[0031] When using the pre-embedded channel 11, the workers position the pre-embedded channel 12 downwards. Then, the pre-embedded rod 13 and the limiting ring 14 are embedded in the concrete. At this point, the workers move the T-bolt 15 into the channel 11, move the T-bolt 15 to a suitable position, and fix the T-bolt 15 in the channel 11 using the fixing component 3. During this process, the fixing component 3 reduces the probability of the T-bolt 15 shaking after prolonged use, thereby improving the stability of the device.
[0032] Multiple blocking grooves 2 are formed on the two opposite inner walls of the channel 11, and fixing grooves 21 are formed on the two opposite side walls of the T-bolt 15. A sliding groove 25 is formed on the inner wall of the two fixing grooves 21. The fixing component 3 is disposed in the channel 11 for fixing the T-bolt 15. The fixing component 3 includes a fixing block 31 and a sliding rod 32. The fixing block 31 is a rectangular block structure and is slidably disposed in the fixing groove 21. The fixing block 31 is slidably connected to the blocking groove 2. The sliding rod 32 is a rectangular rod structure and is slidably disposed in the sliding groove 25. A first inclined surface 33 is formed on the edge where one of the adjacent side walls intersects on the side wall of the fixing block 31 away from the blocking groove 2.
[0033] When the worker needs to fix the T-bolt 15 in the channel 11, the worker needs to slide the slide bar 32 upwards, so that the slide bar 32 gradually approaches and finally presses against the first inclined surface 33, so that the fixing block 31 slides under the action of the slide bar 32, and then one end of the fixing block 31 slides into the blocking groove 2, so that the T-bolt 15 is fixed in the channel 11 under the action of the fixing block 31, thereby reducing the probability of the T-bolt 15 shaking after long-term use, and thus improving the stability of the device.
[0034] A rotating groove 22 is provided through the inner bottom wall of the slide 25. The adjusting bolt 4 is rotatably set in the rotating groove 22 with its axis vertical. The adjusting bolt 4 is threadedly connected to the slide rod 32.
[0035] When the worker needs to slide the slide bar 32 upward, the worker needs to rotate the adjusting bolt 4, so that the slide bar 32 slides upward under the action of the adjusting bolt 4. In this process, the difficulty of the worker sliding the slide bar 32 is reduced, thereby reducing the difficulty of the worker's work.
[0036] A limiting groove 23 is provided on the inner top wall of the fixing groove 21. The limiting block 5 is a rectangular block structure. The limiting block 5 is slidably disposed in the limiting groove 23. The limiting block 5 and the fixing block 31 are fixed to each other.
[0037] When the fixed block 31 slides, the limiting block 5 slides synchronously with the fixed block 31. During this process, the limiting block 5 limits the fixed block 31, thereby reducing the probability of the fixed block 31 separating from the fixed groove 21 and thus improving the stability of the device.
[0038] One end of the reset spring 6 is fixedly mounted on the side wall of the limiting block 5, and the other end of the reset spring 6 is fixedly mounted on the inner wall of the limiting groove 23.
[0039] When the slide bar 32 separates from the fixed block 31, the limiting block 5 slides away from the blocking groove 2 under the action of the return spring 6, thereby causing the fixed block 31 to slide away from the blocking groove 2 under the action of the limiting block 5, thus reducing the difficulty for the staff to reset the fixed block 31 and thus reducing the difficulty of the staff's work.
[0040] A circular groove 24 is provided on the inner wall of the rotating groove 22. The circular plate is rotatably set in the circular groove 24, and its axis coincides with the axis of the adjusting bolt 4. The circular block 7 is fixed to the adjusting bolt 4.
[0041] When the adjusting bolt 4 rotates, the circular block 7 rotates under the action of the adjusting bolt 4. During this process, the circular block 7 reduces the probability of the adjusting bolt 4 moving up and down, thereby improving the stability of the device.
[0042] To reduce the difficulty of the work for the workers, a hexagonal groove 8 is provided on the bottom surface of the adjusting bolt 4, and the bottom surface of the adjusting bolt 4 is flush with the bottom surface of the T-bolt 15. The hexagonal groove 8 reduces the difficulty for the workers to rotate the adjusting bolt 4, thereby reducing the difficulty of the work for the workers.
[0043] To extend the service life of the device, the tank plate 1 is made of stainless steel. The stainless steel material improves the corrosion resistance of the tank plate 1, thereby extending the service life of the device.
[0044] The operating principle of the combined subway tunnel pre-embedded channel in this embodiment is as follows: When using the pre-embedded channel 11, the worker positions the pre-embedded channel 12 downwards. Then, the pre-embedded rod 13 and the limiting ring 14 are embedded in the concrete. At this time, the worker moves the T-bolt 15 into the channel 11, moves the T-bolt 15 to a suitable position, and fixes the T-bolt 15 in the channel 11 using the fixing component 3. During this process, the fixing component 3 reduces the probability of the T-bolt 15 shaking after long-term use, thereby improving the stability of the device.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
