Description

Technical Field

[0001] This invention relates to the field of rail transit equipment technology, specifically a track laying device for a temporary earthmoving passage for the main structure of a station. Background Technology

[0002] Rail transit refers to the technology applied to urban and intercity rail transit systems, encompassing multiple aspects such as vehicles, tracks, and signaling. It mainly includes technologies such as high-speed rail, subways, light rail, and trams. The development of rail transit technology helps improve urban traffic efficiency, reduce congestion, and lower energy consumption, which is of great significance for promoting economic development and environmental protection. However, with the expansion of urban scale and the increase in population, traditional rail transit faces enormous pressure. To meet this challenge, rail transit equipment technology is constantly being innovated, which has promoted the advancement of station track laying technology. By using advanced track laying devices, construction efficiency and quality can be greatly improved, ensuring the smooth progress of rail transit projects.

[0003] Existing technology CN117107566B discloses a track laying device. The technical solution discloses that "This invention relates to the field of railway track technology, specifically disclosing a track laying device. A second arc-shaped body is slidably connected to a first chute, and a third arc-shaped body is slidably connected to a second chute.

This track laying device achieves automatic sliding and alignment of the pulley assembly, saving time and effort, improving automation, and optimizing operational safety."

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

[0005] The purpose of this invention is to provide a track laying device for a temporary earth removal passage for the main structure of a station, 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 excavation passage of a station main structure. The track laying device includes a frame and a base. The frame is fixed to the upper surface of the base. Rollers are installed at the four corners below the base. A telescopic plate is installed below the base. A lifting structure is installed inside the frame. A moving structure is installed below the lifting structure. The moving structure is used to clamp and fix the guide rail. A clamping structure is installed on the upper surface of the base. An automatic welding machine is installed on one side of the clamping structure. The rollers allow the entire device to move between different positions. The telescopic plate can extend to contact the ground when needed, making the entire device stable and providing stable support for subsequent operation. The lifting structure controls the up and down movement of the guide rail. The lifting structure, in conjunction with a position sensor, moves the guide rail to the appropriate position. The moving structure clamps and fixes the guide rail, ensuring stability and accuracy during the laying process. The automatic welding machine is used to complete the welding work between the guide rails, improving the stability and efficiency of the guide rail laying.

[0007] The lifting structure includes two electric motors fixed to the upper end face of the frame. A lead screw is mounted on the output shaft of each electric motor, and the output shaft is rotatably connected to the lead screw. A connecting plate is mounted on the lead screw, and a nut is installed inside the connecting plate. The lead screw engages with the nut. The two electric motors provide power to the lifting structure. The lead screw is rotatably connected to the output end of the electric motor and transmits the power from the electric motor. The rotational motion of the electric motor is converted into linear motion of the nut, which in turn drives the lifting structure to move 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 slide rail is mounted below the mounting plate, and a slider is mounted on the slide rail, slidably connected to the slide rail. A slide rail motor is mounted on one side of the slide rail to drive the slider. A cylinder is mounted below the slider, and a piston rod is mounted below the cylinder. A movable plate is mounted below the piston rod. A fixing mechanism is used to fix 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 and welding. The cylinder controls the extension and retraction of the piston rod to compress the sleepers during laying, minimizing unevenness and improving laying accuracy.

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

[0010] The clamping structure includes a second cylinder, which is fixed to both sides of the upper surface of the base. A second piston rod is mounted on one side of the second cylinder, and a moving block is mounted on one end of the second piston rod. By controlling the extension and retraction of the second piston rod, the second cylinder causes the moving block to fit tightly against the other side of the guide rail, thereby clamping and releasing the guide rail. This ensures the stability of the guide rail during welding, thus guaranteeing welding quality. The clamping structure allows the device to effectively handle guide rails of different widths.

[0011] A limiting structure is installed on one side of the mounting plate. This limiting structure includes a housing and a chain. A second motor is mounted on the housing, and a first gear is mounted on the output shaft of the second motor. The output shaft of the second motor is rotatably connected to the first gear. Three second gears are mounted around the first gear, and the first and second gears are connected by a chain. Three third gears are mounted above the three first gears. A rack is mounted on one side of each third gear, and the third gear meshes with the rack. A rubber suction cup is mounted on one side of the rack. The housing has four through slots, and the rubber suction cup is located on one side of each through slot. The second motor provides power to the limiting structure, driving the chain to rotate and thus driving the first and second gears. The rubber suction cup can adhere to the outer wall of the track, thereby fixing the limiting structure and providing stable support for the operation of the moving structure.

[0012] The frame has a notch on one side, and the automatic welding machine is located on the base on the side of the notch. The automatic welding machine performs preliminary welding at the connection between the two guide rails to prevent the guide rails from shifting due to vibrations generated when the device moves, thus ensuring the stability and accuracy of the guide rail installation.

[0013] A position sensor and a displacement sensor are installed on the upper inner wall of the frame, and a laser emitter is installed on the lower inner wall of the frame. The position sensor, displacement sensor, and laser emitter are electrically connected to the control system. The position sensor monitors the position changes of the lifting structure and transmits the signal to the control system to ensure the precise position of the guide rail during the welding process. The displacement sensor is used to detect the displacement changes of the sleepers relative to the frame, thereby determining whether the sleepers are dented. The laser emitter is used to detect whether the sleepers are tilted.

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

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. This invention uses a combination of lifting structure, moving structure and position sensor to detect the specific position of the guide rail in real time and move the guide rail to the appropriate position. Then, the second cylinder provides power to press the moving plate down, reducing unevenness of the sleepers. At the same time, the moving plate pushes the sleepers to straighten tilted sleepers, improving the stability and accuracy of installation.

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

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

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Please see Figures 1-6 This invention provides a technical solution: a track laying device for a temporary excavation passage of a station's main structure. The track laying device includes a frame 1 and a base 2. The frame 1 is fixed to the upper surface of the base 2. Rollers 3 are installed at the four corners of the base 2. A telescopic plate 4 is installed below the base 2. A lifting structure 5 is installed inside the frame 1. A moving structure 6 is installed below the lifting structure 5. The moving structure 6 is used to clamp and fix the guide rail 9. A clamping structure 7 is installed on the upper surface of the base 2. An automatic welding machine 8 is installed on one side of the clamping structure 7. The rollers 3 allow the entire device to move between different positions. The telescopic plate 4 can extend and contact the ground when needed, making the entire device stable and providing stable support for subsequent operation. The lifting structure 5 controls the up and down movement of the guide rail 9. The lifting structure 5, in conjunction with the position sensor 12, moves the guide rail 9 to the appropriate position. The moving structure 6 clamps and fixes the guide rail 9, ensuring stability and accuracy during the laying process. The automatic welding machine 8 is used to complete the welding work between the guide rails 9, improving the stability and efficiency of the guide rail laying.

[0028] The lifting structure 5 includes two motors 501 fixed to the upper end face of the frame 1. A lead screw 502 is mounted on the output shaft of each motor 501, and the output shaft of the motor 501 is rotatably connected to the lead screw 502. A connecting plate 504 is mounted on the lead screw 502, and a nut 503 is installed inside the connecting plate 504. The lead screw 502 and the nut 503 are engaged. The two motors 501 provide power to the lifting structure 5. The lead screw 502 is rotatably connected to the output end of the motors 501 and transmits the power from the motors 501. The lead screw 502 is engaged with the nut 503, and the rotational motion of the motors 501 can be converted into linear motion of the nut 503. This linear motion, through the connecting plate 504, drives the lifting structure 5 to move up and down, achieving precise adjustment and positioning of the guide rail 9.

[0029] The movable structure 6 includes a mounting plate 601, which is fixed below the connecting plate 504. A slide rail 602 is mounted below the mounting plate 601, and a slider 603 is mounted on the slide rail 602. The slider 603 is slidably connected to the slide rail 602. A motor 607 is mounted on one side of the slide rail 602 to drive the slider 603. A cylinder 604 is mounted below the slider 603, and a piston rod 605 is mounted below the cylinder 604. A movable plate 606 is mounted below the piston rod 605. The movable structure 6 is used to fix and move the guide rail 9. The movable plate 606 fits tightly against the side of the guide rail 9 to ensure that the guide rail 9 does not shift during lifting and welding. The cylinder 604 controls the extension and retraction of the piston rod 605 to compress the sleepers during the laying process, minimizing the unevenness of the sleepers and improving the laying accuracy.

[0030] Four tracks 10 are symmetrically arranged on the inner walls of both sides of the frame 1. One end of the mounting plate 601 is shaped to match the track 10, and the mounting plate 601 is slidably connected to the track 10. During the sliding process, the mounting plate 601 can move stably on the track 10.

[0031] The clamping structure 7 includes a second cylinder 701, which is fixed to both sides of the upper end face of the base 2. A second piston rod 702 is installed on one side of the second cylinder 701, and a moving block 703 is installed at one end of the second piston rod 702. By controlling the extension and retraction of the second piston rod 702, the second cylinder 701 causes the moving block 703 to fit tightly against the other side of the guide rail 9, thereby clamping and releasing the guide rail 9. This ensures that the guide rail 9 remains stable during the welding process, thus guaranteeing the welding quality. The clamping structure 7 enables the device to effectively handle guide rails 9 of different widths.

[0032] A limiting structure 11 is installed on one side of the mounting plate 601. The limiting structure 11 includes a housing 1101 and a chain 1106. A second motor 1102 is installed on the housing 1101. A first gear 1103 is installed on the output shaft of the second motor 1102. The output shaft of the second motor 1102 is rotatably connected to the first gear 1103. Three second gears 1104 are installed around the first gear 1103. The first gear 1103 and the second gear 1104 are connected by the chain 1106. Three third gears 1105 are installed above the three first gears 1103. A rack 1107 is installed on one side of the third gear 1105. The third gear 1105 is meshed with the rack 1107. A rubber suction cup 1108 is installed on one side of the rack 1107. Four through slots are provided on the housing 1101. The rubber suction cup 1108 is located on one side of the through slot. The second motor 1102 provides power to the limiting structure 11. The second motor 1102 drives the chain 1106 to rotate, thereby driving the first gear 1103 and the second gear 1104. The rubber suction cup 1108 can adhere to the outer wall of the track 10 to fix the limiting structure 11, providing stable support for the operation of the moving structure 6.

[0033] A notch is cut on one side of the frame 1, and the automatic welding machine 8 is located on the base 2 on the side of the notch. The automatic welding machine 8 performs preliminary welding on the connection between the two guide rails 9 to prevent the guide rails 9 from shifting due to vibration generated when the device moves, thus ensuring the stability and accuracy of the guide rails 9 installation.

[0034] A position sensor 12 and a displacement sensor 13 are installed on the upper inner wall of the frame 1, and a laser emitter 15 is installed on the lower inner wall of the frame 1. The position sensor 12, displacement sensor 13, and laser emitter 15 are electrically connected to the control system. The position sensor 12 monitors the position change of the lifting structure 5 and transmits the signal to the control system to ensure the precise position of the guide rail 9 during the welding process. The displacement sensor 13 is used to detect the distance between the frame 1 and the sleeper to determine whether the sleeper is dented. The laser emitter 15 is used to detect whether the sleeper is tilted.

[0035] Four electric motors 314 are installed on the upper surface of the base 2. The electric motors 314 are used to drive the rollers 3.

[0036] The working principle of this invention is as follows: During operation, motor 3 (14) drives roller 3 to move, and roller 3 drives the track laying device to move linearly along guide rail 9. Displacement sensor 13 detects the distance between the sleeper and the top of frame 1 in real time. Laser emitter 15 emits laser light to the sleeper in real time. If the distance on both sides is detected to be different, it is determined that there is a depression in the sleeper. The control system controls motor 1 (501) to operate. The main shaft of motor 1 (501) rotates, driving screw 502 to rotate. Screw 502 meshes with nut 503. Screw 502 drives connecting plate 504 and mounting plate 601 to move downward along track 10. After mounting plate 601 moves to the bottom, motor 1 (501) stops operating. Motor 4 (607) operates, driving slider 603 to move above both ends of the sleeper. Motor 4 (607) stops operating. The control system controls motor 2 (1102) to operate. The output shaft of motor 2 (1102) rotates, driving gear 1 (1103) to rotate. Gear 1 (1103) rotates, driving chain 1106 to rotate. Chain 1106 drives... Gear 2 1104 rotates, driving gear 3 1105 to rotate via a connecting shaft. Gear 3 1105's rotation causes the meshing rack 1107 to move. The rack 1107 causes a rubber suction cup 1108 on one side to press tightly against the outer wall of the track 10, fixing the mounting plate 601. The control system controls cylinder 1 604 to operate, pushing piston rod 1 605 downwards. Piston rod 1 605 pushes moving plate 606 downwards, pressing the sleeper against it. The protruding parts of the wooden sleeper are flattened; if the laser emitter 15 detects that the laser irradiation time on the sleeper has increased, it determines that the sleeper is tilted, the cylinder 604 operates, the piston rod 605 pushes the moving plate 606 downward, the position sensor 12 detects that the height of the moving plate 606 is the same as that of the sleeper, the cylinder 604 stops operating, as the frame 1 moves, the moving plate 606 pushes the sleeper to move, straightening the sleeper, after the sleeper is straightened, the cylinder 604 operates, the piston rod 605 drives the moving plate 606 to retract.

[0037] After position sensor 12 detects that the device has moved to the mounting position of guide rail 9, motor 3 14 stops rotating, roller 3 stops rotating, telescopic plate 4 moves, and the bottom end of telescopic plate 4 moves downward to contact the ground, stably fixing the laying device. The external rail carriage transports guide rail 9 into the device. Position sensor 12 monitors the position information of moving plate 606 and guide rail 9 in real time, controls system cylinder 604 to operate, cylinder 604 drives piston rod 605 to move, piston rod 605 drives moving plate 606 to move. Position sensor 12 detects that moving plate 606 and the groove of guide rail 9 are at the same height, cylinder 604 stops operating, and motor 4 607 starts operating. The sliding block 603 moves to the side of the guide rail 9. The sliding block 603 drives the cylinder 604 to move. The cylinder 604 drives the piston rod 605 and the moving plate 606 to move. The moving plate 606 clamps and fixes the guide rail 9. The rail carriage moves out of the device. The control system cylinder 604 is turned on. The cylinder 604 drives the piston rod 605 to move downward. The piston rod 605 drives the moving 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 604 to stop. The motor 607 turns on, driving the sliding block 603 to move. The sliding block 603 drives the moving plate 606 to move towards the inner walls of both sides of the frame 1, placing the guide rail 9 on the sleeper.

[0038] After the position sensor 12 detects that the moving plate 606 has left the guide rail 9, the control system controls the cylinder 701 to operate. The cylinder 701 pushes the piston rod 702 to move. The piston rod 702 drives the moving block 703 to move into the groove of the guide rail 9, fixing and clamping the guide rail 9. The automatic welding machine 8 operates in conjunction with the position sensor 12 to perform preliminary welding at the welding point of the connection between the two guide rails 9. After the welding work is completed, the cylinder 701 operates to retract the piston rod 702. The piston rod 702 drives the moving block 703 to retract, the telescopic plate 4 retracts, the roller 3 re-contacts the ground, and the roller 3 moves forward to lay the next section of the guide rail 9.

Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description.
