Description

Technical Field

[0001] This utility model relates to the field of subway tunnel construction technology, specifically to an automated transportation device for subway tunnel construction materials. Background Technology

[0002] Subway tunnels are underground structures for subway trains and are a key component of urban underground rail transit systems. Their construction methods are diverse, including shield tunneling, cut-and-cover, mining method, New Austrian Tunneling Method (NATM), tunnel boring machine (TBM) method, cut-and-cover method, shallow buried tunneling method, diaphragm wall method, and immersed tube method. During subway tunnel construction, various materials such as steel bars, cement, sand, gravel, and precast components need to be transported frequently. Traditional transportation methods mainly rely on manual labor with small trolleys or simple railcars, requiring multiple workers to operate together. The tunnels are dimly lit, narrow, and have a complex working environment, easily leading to worker fatigue. When manually pushing vehicles, collisions and rollovers are prone to occur due to obstructed vision or uneven road surfaces. The limited capacity of a single transport operation makes it difficult to meet the material supply needs of large-scale construction, reducing transportation efficiency.

[0003] Therefore, the present invention provides an automated transportation device for subway tunnel construction materials to solve the above problems. Utility Model Content

The tunnel is dimly lit, the space is narrow, and the working environment is complex, which can easily lead to personnel fatigue. When manually pushing vehicles, collisions and overturning accidents are likely to occur due to obstructed vision or uneven road surfaces. The single transport capacity is limited, which makes it difficult to meet the material supply needs of large-scale construction and reduces transportation efficiency.

The vehicle body frame is installed above the transport vehicle body. The second connecting seat is fixedly installed above one end of the transport vehicle body and rotatably connected to one side of the lower end of the vehicle body frame. Two servo motors are fixedly installed inside the transport vehicle body. The wheels are rotatably installed on the top of the connecting grooves and contact the upper end of the track. The output end of the servo motor is connected to the wheels. The device also includes an installation groove located at the center of the upper end of the transport vehicle body. A hydraulic cylinder is installed inside the installation groove, and both ends of the hydraulic cylinder are rotatably connected to the transport vehicle body and the vehicle body frame, respectively. Two camera assemblies are fixedly installed on both sides of the vehicle body frame.

[0006] Preferably, rollers are rotatably installed inside both ends of the connecting groove, and the rollers are positioned above and below the track, with the rollers fitting snugly against the track.

[0007] Preferably, an air compressor is fixedly installed at both the front and rear ends of the transport vehicle body, and there are two air compressors.

[0012] Preferably, a cover plate is installed on the upper part of the vehicle body frame. Two cover plates are provided and are rotatably connected by a hinge. A first connecting seat is fixedly installed on the upper end of the vehicle body frame, and one end of the cover plate is rotatably connected to the first connecting seat.

[0013] The beneficial effects of this utility model are as follows: This utility model incorporates a track, a transport vehicle, a camera assembly, an air compressor, a nozzle assembly, wheels, and a servo motor. The transport vehicle is slidably connected to the track, and the servo motor drives the wheels to rotate. As the wheels rotate, they apply a thrust to the transport vehicle, causing it to move along the track and transport materials. The camera assembly detects the road conditions ahead of the transport vehicle, allowing the transport device to avoid obstacles in time. When the transport vehicle moves along the track, the air compressor is activated to generate compressed air. The compressed air is sprayed onto the upper surface of the track through the nozzle assembly, removing debris adhering to the track surface, preventing the wheels from slipping on the track, and improving the operational stability of the transport device. This utility model uses a wireless communication positioning module to obtain the approximate location of the transport device in the tunnel. In conjunction with the positioning markers on the track, the precise location of the transport device is obtained. The wireless communication positioning module uses G / G or WiFi communication technology to transmit the operating status of the transport device to the monitoring center in real time, and at the same time receive control commands issued by the monitoring center to realize remote monitoring of the transport device. This utility model uses a hydraulic cylinder and a second connecting seat. The second connecting seat is rotatably connected to the lower end of the vehicle frame. The hydraulic cylinder applies an upward thrust to the vehicle frame, causing the vehicle frame to rotate along the second connecting seat and flip the vehicle frame at a certain angle, making it easier to unload the materials from the vehicle frame. This invention utilizes a shock-absorbing plate, flexible pad, slots, and partitions. The shock-absorbing plate improves the shock absorption performance of the vehicle frame, providing shock absorption for materials within the frame during transportation. The flexible pad prevents direct contact between the materials and the inner wall of the frame, protecting them from impact damage. For small materials requiring separate transport, the partitions are aligned with the slots and inserted to divide the frame's storage space into multiple compartments, allowing for separate storage and transport. During transport, the cover is closed, creating a closed structure that prevents materials from falling out during transport. Attached Figure Description

[0021] This disclosure aims to address the challenges of relying on manual labor with small trolleys or simple railcars, which requires multiple workers to operate. The dim lighting and confined spaces within tunnels create complex working environments, easily leading to worker fatigue. Manually pushing vehicles is also prone to collisions and rollovers due to obstructed vision or uneven surfaces. Furthermore, the limited capacity of each transport operation makes it difficult to meet the material supply needs of large-scale construction projects, reducing transportation efficiency. Therefore, this disclosure proposes an automated material transport device for subway tunnel construction. The device uses a sliding connection between the transport vehicle and the track. A servo motor drives the wheels to rotate, applying thrust to the transport vehicle as it rotates, propelling it along the track to transport materials. This significantly reduces labor costs and avoids the safety risks of manual labor within the tunnel. As the transport vehicle moves along the track, an air compressor generates compressed air, which is then sprayed onto the upper surface of the track through a nozzle assembly to remove debris, preventing wheel slippage and improving the stability of the transport device. This ultimately meets the material supply needs of large-scale subway tunnel construction.

[0022] like Figures 1 to 7 As shown, an automated material transport device for subway tunnel construction includes a track 1, a transport vehicle body 2, a vehicle frame 3, a second connecting seat 14, a connecting groove 21, wheels 23, and a servo motor 24. The connecting groove 21 is located at the lower end of the transport vehicle body 2, and there are two connecting grooves 21. The track 1 and the connecting groove 21 are correspondingly arranged. The vehicle frame 3 is installed above the transport vehicle body 2. The second connecting seat 14 is fixedly installed above one end of the transport vehicle body 2 and is rotatably connected to one side of the lower end of the vehicle frame 3. The servo motor 24 is fixedly installed inside the transport vehicle body 2, and there are two servo motors 24. The wheels 23 are rotatably installed on the top of the connecting groove 21 and are in contact with the upper end of the track 1. The output end of the servo motor 24 is connected to the wheel 23. The connection also includes a mounting slot 12, which is located at the center of the upper end of the transport vehicle body 2. A hydraulic cylinder 13 is installed inside the mounting slot 12, and the two ends of the hydraulic cylinder 13 are rotatably connected to the transport vehicle body 2 and the vehicle frame 3, respectively. A camera assembly 9 is fixedly installed on both sides of the vehicle frame 3, and there are two camera assemblies 9. Rollers 22 are rotatably installed inside both ends of the connecting slot 21, and the rollers 22 are located above and below the track 1. The rollers 22 are in contact with the track 1. An air compressor 10 is fixedly installed at both the front and rear ends of the transport vehicle body 2, and there are two air compressors 10. A nozzle assembly 11 is fixedly installed on both sides of the air compressor 10, and the nozzle assembly 11 is connected to the air compressor 10. The nozzle assembly 11 is located above the track 1.

[0023] The material is placed into the vehicle frame 3, and the transport vehicle 2 is slidably connected to the track 1. The servo motor 24 is turned on to drive the wheels 23 to rotate. As the wheels 23 rotate, they apply a thrust to the transport vehicle 2, causing the transport vehicle 2 to move along the track 1 to realize material transportation. The camera component 9 detects the road conditions ahead of the transport vehicle 2, so that the transport device can avoid obstacles in time. When the transport vehicle 2 moves along the track 1, the air compressor 10 is turned on to generate compressed air. The compressed air is sprayed onto the upper surface of the track 1 through the nozzle component 11 to remove the debris attached to the upper surface of the track 1 and prevent the wheels 23 from slipping on the track 1. After the material is transported to the position, the hydraulic cylinder 13 is driven to apply an upward thrust to the vehicle frame 3, causing the vehicle frame 3 to rotate along the second connecting seat 14 and flip the vehicle frame 3 at a certain angle to facilitate unloading the material from the vehicle frame 3.

[0024] like Figure 2 , Figure 5 and Figure 7 As shown, a positioning block 19 is fixedly installed at the lower end of one end of the vehicle frame 3. There are two positioning blocks 19. A positioning groove 20 is provided at the upper end of the transport vehicle body 2. There are two positioning grooves 20, and the positioning blocks 19 and positioning grooves 20 are set in correspondence.

[0025] Positioning block 19 is inserted into positioning slot 20 to laterally limit the falling vehicle frame 3, preventing the vehicle frame 3 from swaying and shifting during transportation, and improving the overall stability of the transportation device.

[0026] like Figure 1 As shown, two audible and visual warning lights 6 are fixedly installed on both sides of the vehicle body frame 3. There are four audible and visual warning lights 6, and the four audible and visual warning lights 6 are located at the four corners of the vehicle body frame 3. There are two anti-collision mechanisms 8 fixedly installed on both sides of the vehicle body frame 3.

[0027] The audible and visual warning light 6 is illuminated during transportation and flashes continuously while the transportation device is running, reminding staff in the tunnel to take precautions. When the transportation device malfunctions or encounters an obstacle, the audible and visual warning light 6 will sound an alarm to remind staff to handle the situation promptly. When the vehicle frame 3 collides with other objects, the anti-collision mechanism 8 will make contact with other objects first. The anti-collision mechanism 8 can absorb the impact force of the collision, reduce the damage to the vehicle frame 3 and the materials, and improve the material transportation efficiency.

[0028] like Figure 1 As shown, a wireless communication positioning module 7 is fixedly installed on one side of the vehicle frame 3.

[0029] The wireless communication positioning module 7 is used to obtain the approximate location of the transport device in the tunnel. In conjunction with the positioning mark on track 1, it obtains the precise location of the transport device. The wireless communication positioning module 7 uses 4G / 5G or WiFi communication technology to transmit the operating status of the transport device to the monitoring center in real time. At the same time, it receives control commands issued by the monitoring center to realize remote monitoring of the transport device.

[0030] like Figure 1 , Figure 3 and Figure 4 As shown, a shock-absorbing plate 15 is fixedly installed at the bottom of the vehicle frame 3, a flexible pad 16 is attached to the inner wall of the vehicle frame 3, a slot 17 is provided on the inner wall of the vehicle frame 3, a partition 18 is installed inside the vehicle frame 3, and the two ends of the partition 18 are correspondingly set with the slot 17. The partition 18 is slidably connected to the vehicle frame 3. A cover plate 4 is installed on the top of the vehicle frame 3. There are two cover plates 4, and the two cover plates 4 are rotatably connected by a hinge. A first connecting seat 5 is fixedly installed at the upper end of the vehicle frame 3, and one end of the cover plate 4 is rotatably connected to the first connecting seat 5.

[0031] The shock-absorbing plate 15 improves the shock absorption performance of the vehicle frame 3 and plays a shock-absorbing role for the materials in the vehicle frame 3 during transportation. The flexible pad 16 prevents the materials from directly contacting the inner wall of the vehicle frame 3, protecting the materials in the vehicle frame 3 and preventing them from being damaged by bumps. When small-volume materials need to be transported separately, the partition 18 is aligned with the slot 17 and inserted to divide the storage space of the vehicle frame 3 into multiple spaces, allowing the materials to be stored and transported separately. During transportation, the cover plate 4 is closed, opening and closing the upper part of the vehicle frame 3, forming a closed structure that prevents the materials in the vehicle frame 3 from falling out during transportation.

[0032] During operation, the materials to be transported are placed in the vehicle frame 3. Depending on the size of the materials and transportation requirements, partitions 18 are selectively installed on the vehicle frame 3. After loading, the top of the vehicle frame 3 is closed using a cover plate 4. The servo motor 24 is activated to rotate the wheels 23. As the wheels 23 rotate, they apply thrust to the transport vehicle 2, causing it to move along the track 1, thus transporting the materials. During the transport process, the audible and visual warning lights 6 are illuminated and flash continuously while the transport device is running, alerting workers in the tunnel to take precautions. The camera assembly 9 monitors the transport vehicle. 2. The road conditions ahead are detected, and obstacles are avoided in time based on the detection results. When the transport vehicle 2 moves along the track 1, the air compressor 10 is turned on to generate compressed air. The compressed air is sprayed onto the upper surface of the track 1 through the nozzle assembly 11 to remove the debris attached to the upper surface of the track 1 and prevent the wheels 23 from slipping on the track 1. After the material is transported to the position, the hydraulic cylinder 13 is driven to apply an upward oblique thrust to the vehicle frame 3, which drives the vehicle frame 3 to rotate along the second connecting seat 14 and flip the vehicle frame 3 at a certain angle to facilitate the unloading of the material in the vehicle frame 3.

[0033] Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
