Description

Technical Field

[0001] The present invention relates to the technical field of rail transportation equipment, in particular to a track laying device for a temporary excavated passage of a station main structure. Background Art

[0002] Rail transit refers to the technology applied to urban and intercity rail transit systems, covering multiple aspects such as vehicles, lines, and signals. It mainly includes high-speed railways, subways, light rails, trams and other technologies. The development of rail transit technology helps to improve urban traffic efficiency, reduce congestion, and reduce energy consumption. It is of great significance to promote economic development and environmental protection. However, with the expansion of urban scale and the increase in population, traditional rail transit is facing tremendous pressure. To meet this challenge, rail transit equipment technology is constantly innovating, which has promoted the advancement of station track laying technology. By using advanced track laying equipment, construction efficiency and quality can be greatly improved to ensure the smooth progress of rail transit projects.

[0004] Although the prior art has disclosed a track laying device, there are still some shortcomings. Specifically, in the actual production operation process, after the laying device lays the guide rails on the sleepers, the sleepers are uneven, which requires the guide rails to be moved during subsequent installation. Moreover, after the guide rails are laid, the subsequent movement of the entire device will cause the guide rails to vibrate and deviate, resulting in errors in the guide rail installation. Summary of the Invention

[0005] The object of the present invention is to provide a track laying device for a temporary excavation passage of a station main structure, so as to solve the problems raised in the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a track laying device for a temporary excavated passageway in a station main structure, the track laying device comprising a frame and a base, the frame being fixed to the upper end surface of the base, rollers being mounted at the four corners of the base, a telescopic plate being mounted below the base, a lifting structure being mounted inside the frame, a movable structure being mounted below the lifting structure, the movable structure being used to clamp and fix the guide rails, a clamping structure being mounted on the upper end surface of the base, and an automatic welding machine being mounted on one side of the clamping structure. The rollers enable the entire device to move between different positions, the telescopic plate being able to extend and contact the ground when needed, thereby stabilizing the entire device and providing stable support during subsequent operation, the lifting structure controlling the up and down movement of the guide rails, and cooperating with a position sensor to move the guide rails to the appropriate position, the movable structure clamping and fixing the guide rails to ensure stability and accuracy during the laying process, and the automatic welding machine being used to weld between the guide rails, thereby improving the stability and efficiency of the guide rail laying process.

[0007] The lifting structure includes two motors (1), two of which are fixed to the upper end surface of the frame. A lead screw is mounted on the output shaft of each motor (1), which is rotatably connected to the lead screw. A connecting plate is mounted on the lead screw, and a nut is mounted within the connecting plate. The lead screw and the nut are meshed and connected. The two motors (1) provide power for the lifting structure. The lead screw is rotatably connected to the output end of each motor (1), which is used to transmit power from each motor (1). The lead screw and the nut are meshed and connected. The rotational motion of the motor (1) is converted into linear motion of the nut, which in turn drives the lifting structure up and down via the connecting plate, achieving precise adjustment and positioning of the guide rail.

[0008] The movable structure includes a mounting plate fixed below a connecting plate. A first slide rail is mounted below the mounting plate. A slider is mounted on the slide rail, and the slider is slidably connected to the first slide rail. A slide rail motor is mounted on one side of the slide rail, and the slide rail motor is used to drive the slider. A first cylinder is mounted below the slider, a first piston rod is mounted below the first cylinder, and a movable plate is mounted below the first piston rod. A fixing mechanism is used to secure and place the guide rail. The movable plate fits tightly against the side of the guide rail to ensure that the guide rail does not shift during lifting, lowering, and welding. The first cylinder controls the extension and contraction of the first piston rod, squeezing the sleepers during the laying process to minimize unevenness and improve laying accuracy.

[0009] Four slide rails 2 are symmetrically arranged on the inner walls on both sides of the frame, one end of the mounting plate is shaped to match the slide rail 2, and the mounting plate is slidably connected to the slide rail 2. During the sliding process, the mounting plate can achieve stable movement on the slide rail 2.

[0010] The clamping structure includes a second cylinder, fixed to both sides of the upper end surface of the base. A second piston rod is mounted on one side of the cylinder, and a movable block is mounted on one end of the second piston rod. By controlling the extension and retraction of the second piston rod, the movable block tightly fits against the other side of the guide rail, clamping and loosening the guide rail. This ensures the rail remains stable during welding, thereby guaranteeing weld quality. The clamping structure enables the device to effectively handle guide rails of varying widths.

[0011] A limiting structure is mounted on one side of the mounting plate. The limiting structure comprises a housing and a chain. Motor 2 is mounted on the housing, and Gear 1 is mounted on the output shaft of Motor 2. The output shaft of Motor 2 is rotatably connected to Gear 1. Three Gears 2 are mounted around Gear 1, connected to Gear 2 via a chain. Three Gears 3 are mounted above the three Gears 1. A rack is mounted on one side of Gear 3, meshing with the rack. Rubber suction cups are mounted on one side of the rack. The housing is provided with four through slots, and the rubber suction cups are located on one side of the through slots. Motor 2 provides power for the limiting structure, driving the chain to rotate, thereby driving Gear 1 and Gear 2. The rubber suction cups can adhere to the outer wall of the track, thereby securing the limiting structure and providing stable support for the operation of the mobile structure.

[0012] A notch is formed on one side of the frame, and the automatic welding machine is located on the base of the notch. The automatic welding machine performs preliminary welding on the connection between the two guide rails to prevent the guide rails from shifting due to vibration generated when the device moves, thereby ensuring the stability and accuracy of the guide rail laying.

[0013] A position sensor and displacement sensor are mounted on the upper inner wall of the frame, while a laser emitter is mounted on the lower inner wall. These sensors, displacement sensors, and laser emitter are electrically connected to the control system. The position sensor monitors the position changes of the lifting structure and transmits signals to the control system to ensure the precise position of the guide rail during welding. The displacement sensor detects the displacement changes between the sleeper and the frame to determine whether the sleeper is dented. The laser emitter detects whether the sleeper is tilted.

[0014] Four motors three are installed on the upper end surface of the base, and the motors three are used to drive the rollers.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The present invention detects the specific position of the guide rail in real time and moves the guide rail to the appropriate position through the cooperation of the lifting structure, the moving structure and the position sensor. Then, the cylinder 2 provides power to press the moving plate downward to reduce the unevenness of the sleepers. At the same time, the moving plate pushes the sleepers to straighten the tilted sleepers, thereby improving the stability and accuracy of the installation.

[0017] 2. The present invention uses the limiting structure on the mounting plate to fix the mounting plate during the process of pressing the guide rail, providing support for the operation of the cylinder, ensuring the stability and accuracy of the guide rail during use, thereby improving the performance and reliability of the entire mechanical system.

[0018] 3. The present invention automates the welding process by introducing an automatic welding machine, performs preliminary welding on the connection between the two guide rails, prevents the guide rails from being offset due to vibrations generated when the device moves, and ensures the stability and accuracy of the guide rail laying.

The laser emitter 15 is used to detect whether the sleeper is tilted.

[0035] Four motors 3 14 are mounted on the upper end surface of the base 2 , and the motors 3 14 are used to drive the rollers 3 .

[0036] The working principle of the present invention is as follows: during the working process, the motor three 14 operates to drive the roller 3 to move, and the roller 3 drives the track laying device to move in a straight line along the guide rail 9. The displacement sensor 13 detects the distance between the sleeper and the top of the frame 1 in real time, and the laser emitter 15 emits a laser to the sleeper in real time. If it is detected that the distances on both sides are different, it is determined that there is a depression in the sleeper, and the control system controls the motor one 501 to operate. The main shaft of the motor one 501 rotates to drive the screw rod 502 to rotate. The screw rod 502 engages with the nut 503, and the screw rod 502 drives the connecting plate 504 and the mounting plate 601 to move downward along the track 10. After the mounting plate 601 moves to the bottom, the motor one 501 stops operating, and the motor four 607 operates to drive the slider 603 to move above the two ends of the sleeper. The motor four 607 stops operating, and the control system controls the motor two 1102 to operate. The output shaft of the motor two 1102 rotates to drive the gear one 1103 to rotate, and the gear one 1103 rotates to drive the chain 1106 to rotate, and the chain 1106 drives Gear 2 1104 rotates, and gear 2 1104 drives gear 3 1105 to rotate through the connecting shaft. Gear 3 1105 rotates and drives the rack 1107 meshing with it to move. The rack 1107 drives the rubber suction cup 1108 on one side to stick to the outer wall of the track 10, fixing the mounting plate 601. The control system controls the operation of cylinder 1 604, and cylinder 1 604 pushes piston rod 1 605 to move downward. The piston rod 1 605 pushes the moving plate 606 to move downward. The moving plate 606 squeezes the sleepers, and the sleepers are fixed. If the laser emitter 15 detects that the time the laser irradiates the sleeper becomes longer, it is determined that the sleeper is tilted, and the cylinder 604 is operated, and the piston rod 605 pushes the movable plate 606 to move downward. The position sensor 12 detects that the height of the movable plate 606 is the same as that of the sleeper, and the cylinder 604 stops operating. As the frame 1 moves, the movable plate 606 pushes the sleeper to move and straighten the sleeper. After the sleeper is straightened, the cylinder 604 is operated, and the piston rod 605 drives the movable plate 606 to retract.

[0037] After the position sensor 12 detects that the device moves to the installation position of the guide rail 9, the motor three 14 stops running, the roller 3 stops rotating, the telescopic plate 4 starts running, and the bottom end of the telescopic plate 4 moves downward to contact the ground, stably fixing the laying device. The external track vehicle transports the guide rail 9 to the interior of the device. The position sensor 12 monitors the position information of the movable plate 606 and the guide rail 9 in real time, and the control system cylinder 1 604 starts running. The cylinder 1 604 drives the piston rod 1 605 to move, and the piston rod 1 605 drives the movable plate 606 to move. The position sensor 12 detects that the movable plate 606 and the groove of the guide rail 9 are at the same height. The cylinder 1 604 stops running, and the motor four 607 starts running with The movable slider 603 moves toward the guide rail 9, and the slider 603 drives the cylinder 1 604 to move, and the cylinder 1 604 drives the piston rod 1 605 and the movable plate 606 to move, and the movable plate 606 clamps the guide rail 9 and fixes it. The rail car moves out of the device, and the control system cylinder 1 604 operates, and the cylinder 1 604 drives the piston rod 1 605 to move downward, and the piston rod 1 605 drives the movable plate 606 to move downward. After the position sensor 12 detects that the guide rail 9 is in contact with the sleeper, the control system controls the cylinder 1 604 to stop running, and the motor 4 607 operates to drive the slider 603 to move, and the slider 603 drives the movable plate 606 to move toward the inner walls on both sides of the frame 1 to place the guide rail 9 on the sleeper.

[0038] After the position sensor 12 detects that the movable plate 606 leaves the guide rail 9, the control system controls the operation of the cylinder 2 701, and the cylinder 2 701 pushes the piston rod 2 702 to move. The piston rod 2 702 drives the movable block 703 to move into the groove of the guide rail 9 to fix and clamp the guide rail 9. The automatic welding machine 8 operates and cooperates with the position sensor 12 to perform preliminary welding on the welding points at the connection of the two guide rails 9. After the welding work is completed, the cylinder 2 701 operates to retract the piston rod 2 702, and the piston rod 2 702 drives the movable block 703 to retract, the telescopic plate 4 is retracted, and the roller 3 contacts the ground again, and the roller 3 moves forward to lay the next section of the guide rail 9.
