Description

Technical Field

[0001] This utility model relates to the field of rail transit technology, and in particular to a rail transit maintenance structure. Background Technology

[0002] As a crucial component of modern urban transportation, the maintenance of construction sites for rail transit facilities is of paramount importance. Traditional maintenance structures used during rail transit construction typically employ fixed fencing or temporary protective measures, which present the following problems:

[0003] 1. Complex installation and dismantling: Traditional rail transit construction typically uses fixed barriers or temporary protective measures for the maintenance structure, which makes the construction process complex and time-consuming, affecting the efficiency of rail transit construction.

[0004] 2. Insufficient safety: When the maintenance structure is used for protection, it is subjected to external impact. At this time, the maintenance structure is a rigid impact, which can easily cause deformation of the maintenance structure, resulting in damage to the maintenance structure and reducing its service life.

[0005] To address the aforementioned issues, this application proposes a rail transit maintenance structure. Utility Model Content

[0006] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a rail transit maintenance structure. By setting up a buffer disassembly and assembly mechanism, the maintenance plate and the two columns can be installed and disassembled. The operation is simple, the assembly efficiency is improved, and the maintenance plate can be buffered and protected, thus protecting the maintenance structure and extending the service life of the device.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A rail transit maintenance structure includes a maintenance plate with columns on both sides. Each column has a sliding groove at its opposite ends. Two buffer disassembly mechanisms are provided between the maintenance plate and each column. Each buffer disassembly mechanism includes a fixing rod fixedly connected to the inner wall of the sliding groove. A sliding block is slidably connected to the outer wall of the fixing rod, located within the sliding groove and slidably connected to its inner wall. A buffer spring is fitted onto the outer wall of the fixing rod, with its two ends fixedly connected to the inner wall of the sliding groove and the outer wall of the sliding block, respectively. A damper is fixedly connected to the outer wall of the sliding block and the inner wall of the sliding groove. A T-shaped pin is slidably connected to the maintenance plate. A connecting spring is fitted onto the outer wall of the T-shaped pin, with its two ends fixedly connected to the maintenance plate and the T-shaped pin, respectively. A limit hole is provided on the sliding block, and the T-shaped pin is inserted into the limit hole.

[0009] Preferably, each of the columns is fixedly connected to a connecting column at its bottom, and each of the connecting columns is fixedly connected to a base at its bottom. Each base has four through holes, and the four through holes are arranged in a rectangular pattern.

[0010] Preferably, a camera is fixedly connected to the top of each column, and the column and the camera are installed and fixed together by multiple bolts.

[0011] Preferably, a plurality of warning lights are fixedly connected to the top of the maintenance plate, and the plurality of warning lights are distributed at equal intervals.

[0012] Preferably, a vibration sensor and a temperature sensor are fixedly connected to the top of the maintenance plate.

[0013] Preferably, the maintenance plate has a mounting groove, and the sliding block is inserted into the mounting groove.

[0014] Compared with the prior art, the advantages of this utility model are as follows:

[0015] 1. The staff installs the maintenance plate on the column. One staff member holds the two T-shaped pins and moves them back to back. During this process, the connecting spring is stretched. Another staff member moves the maintenance plate to insert the two sliding blocks into the corresponding mounting slots. Then, the T-shaped pins are released and inserted into the corresponding limit holes to complete the installation and fixation between the maintenance plate and the column. The operation is simple and improves the assembly efficiency.

[0016] 2. By assembling this maintenance structure, its volume can be reduced, making it easier to install, disassemble, and transport, and thus applicable to a wide range of situations.

[0017] 3. The construction site can be monitored via cameras, and the temperature sensor can detect the temperature at the construction site, allowing for real-time understanding of the situation.

[0018] 4. When the maintenance plate is subjected to external impact, the maintenance plate will move. The movement of the maintenance plate will drive the sliding block on one side to move on the fixed rod. During this process, the buffer spring will extend and retract, thereby buffering and protecting the maintenance plate. The damper can dampen the maintenance plate so that it eventually tends to stabilize, protecting the maintenance structure and extending the service life of the device.

[0019] In summary, by setting up a buffer disassembly and assembly mechanism, the maintenance plate and the two columns can be installed and disassembled. The operation is simple, the assembly efficiency is improved, and the maintenance plate can be buffered and protected, thus protecting the maintenance structure and extending the service life of the device.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figures 1-3 A rail transit maintenance structure includes a maintenance plate 1. Columns 2 are provided on both sides of the maintenance plate 1. A connecting column 3 is fixedly connected to the bottom of each column 2. A base 4 is fixedly connected to the bottom of each connecting column 3. Four through holes are provided on each base 4. The four through holes are arranged in a rectangular pattern. The column 2, connecting column 3, and base 4 can be installed and fixed on the ground by locking bolts engaging with the through holes, thereby fixing the maintenance plate 1.

[0026] Each of the two columns 2 has a sliding groove 5 at its opposite ends. Two buffer disassembly mechanisms are provided between the maintenance plate 1 and each column 2. Each buffer disassembly mechanism includes a fixed rod 6 fixedly connected to the inner wall of the sliding groove 5. A sliding block 7 is slidably connected to the outer wall of the fixed rod 6. The sliding block 7 is located within the sliding groove 5 and slidably connected to its inner wall. The end of the sliding block 7 furthest from the maintenance plate 1 abuts against the inner wall of the sliding groove 5. A buffer spring 9 is fitted onto the outer wall of the fixed rod 6. Both ends of the buffer spring 9 are fixedly connected to the inner wall of the sliding groove 5 and the outer wall of the sliding block 7, respectively. A damper 10 is fixedly connected to the outer wall of the sliding block 7 and the inner wall of the sliding groove 5. When the maintenance plate 1 is impacted by external forces, the maintenance plate 1 moves, causing the sliding block 7 to move on the fixed rod 6. During this process, the buffer spring 9 deforms, providing buffer protection for the impacted maintenance plate 1. The damper 10 also helps the maintenance plate 1 eventually stabilize.

[0027] The maintenance plate 1 has an installation groove 8, and the sliding block 7 is inserted into the installation groove 8. A T-shaped pin 11 is slidably connected to the maintenance plate 1. A connecting spring 12 is sleeved on the outer wall of the T-shaped pin 11. The two ends of the connecting spring 12 are fixedly connected to the maintenance plate 1 and the T-shaped pin 11, respectively. A limit hole 13 is opened on the sliding block 7, and the T-shaped pin 11 is inserted into the limit hole 13. By moving the T-shaped pin 11, the T-shaped pin 11 can be inserted into the limit hole 13, which allows the maintenance plate 1 and the column 2 to be installed and disassembled. The operation is simple.

[0028] Each column 2 is fixedly connected to a camera 14 at its top, enabling real-time monitoring of the rail transit construction site. The column 2 and camera 14 are fixedly installed with multiple bolts. The maintenance plate 1 is fixedly connected to multiple alarm lights 15 at equal intervals, which illuminate the maintenance plate 1 at night and remind people to stay away from the construction site for rail transit ground maintenance. The maintenance plate 1 is also fixedly connected to a vibration sensor 16 and a temperature sensor 17. The vibration sensor 16 monitors the vibration of the maintenance plate 1, and the temperature sensor 17 monitors the temperature during construction, allowing for timely understanding of the construction environment. The vibration sensor 16, temperature sensor 17, and camera 14 are electrically connected to the backend via signal lines to monitor the construction site conditions in a timely manner.

[0029] In this utility model, when maintaining the construction site of rail transit, the assembly of this maintenance structure involves first installing a column 2, a connecting column 3, and a base 4 on the ground on one side of the rail transit under construction. The column 2, connecting column 3, and base 4 are securely installed on the ground by tightening the bolts and the through holes. Next, the maintenance plate 1 is installed on the column 2. One worker holds two T-shaped pins 11 and moves them back-to-back, during which the connecting spring 12 is stretched. Another worker moves the maintenance plate 1 to insert two sliding blocks 7 into the corresponding mounting slots 8, then releases the T-shaped pins 11 and inserts them into the corresponding limiting holes 13, completing the installation and fixation between the maintenance plate 1 and the column 2. Finally, the worker installs and fixes another column 2 to the maintenance plate 1, and then installs the other column 2 on the ground, completing the installation and fixation of the other column 2. By assembling this maintenance structure, its volume can be reduced. This design facilitates installation, disassembly, and transportation, and has a wide range of applications. During maintenance at rail transit construction sites, camera 14 monitors the site, and temperature sensor 17 detects the temperature, allowing for real-time monitoring of the site conditions. When maintenance plate 1 is impacted, it moves, causing sliding block 7 on one side to move on fixed rod 6. During this process, buffer spring 9 extends and retracts, providing cushioning protection for maintenance plate 1. Damper 10 dampens the plate, stabilizing it. Vibration sensor 16 detects vibrations as maintenance plate 1 moves. Abnormal vibrations are detected in the background (vibration sensor 16 is electrically connected to the background for real-time detection of abnormal vibrations; this technology is existing). This allows staff to inspect the location, ensuring construction safety.

[0030] This invention solves the problems of complex installation and disassembly and insufficient safety in the prior art by setting up a buffer disassembly mechanism.
