Each supporting guide wheel 202 includes a guide wheel body 2021, a connecting member 2022 and a rotating member 2023. The connecting member 2022 passes through the rotating member 2023 and is fixedly connected to the guide wheel body 2021.

[0040] The supporting guide wheel 202 fits with the precast panel 4, which facilitates the sliding of the guiding wheel body 2021 along the length direction of the precast panel 4, and plays a guiding role for the rail laying device. At the same time, multiple supporting guide wheels 202 are fixedly connected to the walking beam 201 at one end away from the precast panel 4, and the walking beam 201 is supported outward by the action force between the supporting guide wheel 202 and the precast panel 4.

The walking wheels 203 at both ends of the walking beam 201 can walk in a straight line.

[0041] The connecting member 2022 is fixedly connected to the guide wheel body 2021 after passing through the second rotating member 2025. The distance between the walking beam 201 and the prefabricated board 4 is controlled by the connecting member 2022. The length of the connecting member 2022 passing through the second rotating member 2025 is adjusted according to the on-site track conditions. The connecting member 2022 can be a threaded rod with adjustable length. The length of the connecting member 2022 is adjusted according to the distance between the walking beam 201 and the prefabricated board 4. After the adjustment, the guide wheel body 2021 is fitted with the prefabricated board 4. The end of the connecting member 2022 away from the guide wheel body 2021 passes through the second rotating member 2025 from the side close to the prefabricated board 4 to the side close to the walking beam 201. The external thread of the connecting member 2022 matches the internal thread of the threaded hole on the second rotating member 2025, so that the connecting member 2022 is threadedly connected to the second rotating member 2025. If the connector 2022 is assembled from a plurality of short connectors, the two ends of the short connector are respectively provided with internal threads and external threads, and the internal threads match the external threads so that the plurality of short connectors can be assembled into a connector 2022 of any length. When the connector 2022 is a retractable threaded rod, the outer side of the connector 2022 is provided with external threads, and after the distance between the walking beam 201 and the prefabricated plate 4 is adjusted, the portion of the connector 2022 that exceeds the distance is retracted.

[0042] By adjusting the distance between the walking beam 201 and the prefabricated plate 4 through the connecting piece 2022, the rail laying device can be applied to the laying of rails on any track bed, thereby improving the applicability of the equipment.

[0043] Each second rotating member 2025 is provided with a first rotating member 2024 on both sides, one end of the first rotating member 2024 is fixedly connected to the walking beam 201, and the second rotating member 2025 is rotatably connected to the two first rotating members 2024 through a slide groove 2026. The second rotating member 2025 can slide arbitrarily in the slide groove to adjust the angle between the guide wheel body 2021 and the prefabricated plate 4 so that the guide wheel body 2021 can slide along the prefabricated plate 4. Figure 3 As shown, the rotating member 2023 further includes a limiting component 2027 . Two limiting components 2027 are disposed in each slide groove 2026 . Each limiting component 2027 can slide along the slide groove 2026 to limit the rotation of the second rotating member 2025 .

[0044] The slide groove 2026 is semicircular and the semicircular opening is downward. A limiting component 2027 matching the shape of the slide groove 2026 is arranged in the slide groove, and the limiting component 2027 has an automatic locking function. Two limiting components 2027 are respectively arranged at both ends of the slide groove 2026. The second rotating member 2025 slides in the slide groove 2026 to adjust the angle between the guide wheel body 2021 and the prefabricated plate 4. After the adjustment is completed, the two limiting components 2027 are slid close to the second rotating member 2025. When the two limiting components 2027 are in contact with the rotating shaft 2028 of the second rotating member 2025, the limiting components 2027 are locked to fix the position of the second rotating member 2025 in the slide groove 2026.

[0045] Furthermore, the limiting component 2027 is a retractable structure (not shown in the figure), and a limiting component 2027 is respectively provided at the two side ends of the slide groove 2026. Knobs are provided at both ends of the slide groove 2026. The limiting component 2027 can be screwed into and out of the slide groove 2026 by rotating the knob. The end of the limiting component 2027 matches the shape of the rotating shaft of the second rotating member 2025, so that the limiting component 2027 can clamp the rotating shaft 2028 of the second rotating member 2025.

[0046] The second rotating member 2025 is slid along the slide groove 2026 to adjust the angle of the guide wheel body 2021 so that the guide wheel body 2021 can match any prefabricated plate 4, thereby improving the applicability of the rail laying device.

[0047] Furthermore, the slide groove 2026 may also be arc-shaped.

[0048] like Figure 2 , Figure 4 As shown, the walking wheel 203 includes a walking wheel body 2031, a first connecting plate 2032, a second connecting plate 2035 and an electric transmission component 2033. The first connecting plate 2032 is connected to the end of the walking beam 201. There are two second connecting plates 2035. The two second connecting plates 2035 are spaced apart on the inner side of the walking wheel body 2031. The lower part of the second connecting plate 2035 is connected to the walking wheel body 2031. The electric transmission component 2033 is arranged in the two second connecting plates 2035 to drive the walking wheel body 2031 to rotate. The walking wheel body 2031 is rotatably connected to the first connecting plate 2032 through the second connecting plate 2035.

[0049] The first connecting plate 2032 is a square plate, which is connected to the end of the walking beam 201 by screws. Adjustment slides 2034 are provided near the four corners of the first connecting plate 2032. The four adjustment slides 2034 are symmetrically arranged along the central axis of the first connecting plate 2032. The second connecting plate 2035 is connected to the connecting plate 2032 by the adjustment slides 2034. The angle between the second connecting plate 2035 and the first connecting plate 2032 can be adjusted by the four adjustment slides 2034. Since the second connecting plate 2035 is fixedly connected to the walking wheel body 2031, the angle between the walking wheel body 2031 and the horizontal direction can be adjusted. The walking wheel body 2031 can be perpendicular to the horizontal direction or have a certain angle with the horizontal direction, so that the rail laying device can adapt to different track conditions.

[0050] The second connecting plate 2035 is provided with an adjusting slide shaft that matches the size of the adjusting slideway 2034. The angle between the walking wheel body 2031 and the horizontal direction is adjusted by sliding the adjusting slide shaft in the adjusting slideway 2034. A buckle is provided in the adjusting slideway 2034. After the position of the adjusting slide shaft is adjusted, the adjusting slide shaft is fixed by the buckle, so that the angle between the walking wheel body 2031 and the horizontal direction is fixed, and the walking wheel body 2031 can walk along the inclined road surface.

[0051] The electric transmission component 2033 provides power for the movement of the walking wheel body 2031 .

[0052] like Figure 1 , Figure 2 As shown, the support mechanism 3 includes a first support rod 301, a second support rod 302 and a third support rod 303. The bottom of the second support rod 302 is threadedly connected to the walking beam 201 and is perpendicular to the walking beam 201. The first support rod 301 and the third support rod 303 are spaced apart on both sides of the second support rod 302 and are threadedly connected to the walking beam 201. The ends of the first support rod 301 and the third support rod 303 away from the walking beam 201 are both close to the second support rod 302 and extend upward to form a groove 304.

[0053] The second support rod 302 is a rectangular long rod, and the first support rod 301 and the third support rod 303 are both rectangular long rods with inclined surfaces at both ends. One end of the first support rod 301 and the third support rod 303 are both threadedly connected to the walking beam 201. Since the ends of the first support rod 301 and the third support rod 303 are both inclined surfaces, the first support rod 301 and the third support rod 303 are both close to the second support rod 302 after being connected to the walking beam 201, and the first support rod 301 and the third support rod 303 form an inverted V-shaped structure. The inner sides of the ends of the first support rod 301 and the third support rod 303 away from the walking beam 201 are parallel, and the first support rod 301, the second support rod 302 and the third support rod 303 are welded together at one end away from the walking beam 201, and a groove 304 is formed at the top of the second support rod 302 after welding.

[0054] like Figure 5 As shown, the electric transmission component 2033 includes a motor 2036, a reducer 2037, a gear 2038 and a chain 2039. The output end of the motor 2036 is connected to the input end of the reducer 2037, the output end of the reducer 2037 is connected to the rotating shaft of the gear 2038, and the gear 2038 is connected to the walking wheel body 2031 through the chain 2039.

[0055] The motor 2036 is a servo motor, and the reducer 2037 is an RV gear reducer. The reducer 2037 adjusts the rotation speed of the motor 2036. Through the cooperation of the reducer 2037, the gear 2038 and the chain 2039, the walking wheel body 2031 moves forward.

[0056] like Figure 1 As shown, the hoisting mechanism 1 includes a crossbeam 101 and an electric hoist 102 . The left and right ends of the crossbeam 101 are connected to the groove 304 . The electric hoist 102 is arranged on the crossbeam 101 and can slide along the crossbeam 101 .

[0057] The crossbeam 101 is a 16# I-beam, which is both a load-bearing beam and a transverse track of an electric hoist 102. The electric hoist is a 3t chain electric hoist. The hook 103 on the lower side of the electric hoist 102 is used to fix the rail.

[0058] Furthermore, a retractable left hook and right hook are respectively arranged on the left and right sides of the hook 103, and retractable steel wires are arranged on the left hook and the right hook. By pulling the left hook, the left hook can be extended outward on the left side of the hook 103, and by pulling the right hook, the right hook can be extended outward on the right side of the hook 103. Fasteners are arranged on the left hook and the right hook. When transporting rails, the hook 103 and the left hook are stretched to the left side of the hook 103 and separated from the hook 103 by a distance, and the right hook is stretched to the right side of the hook 103 and separated from the hook 103 by a distance. The hook 103, the left hook, and the right hook are respectively fixed to the rails. With the assistance of the left hook and the right hook, the rails are always kept balanced during transportation to avoid casualties caused by the rails slipping.

[0059] Furthermore, when transporting long rails, two rail laying devices can be used simultaneously, with a distance between the two rail laying devices. The electric hoists 102 of the two rail laying devices respectively lift the two ends of the rails, and fix the rails through the hooks 103 to ensure smooth transportation of the cylinders. Through the cooperation of the two rail laying devices, rails of any length can be transported, avoiding casualties caused by accidents when the staff transport the rails.

[0060] After the rails are transported to the destination, the electric hoist 102 slides along the crossbeam 101 to lay the rails to the target position, thereby avoiding the need for workers to move the rails and reducing their labor intensity.

[0061] like Figure 1 and Figure 6 As shown, the slab track bed rail laying device also includes a power supply mechanism 5 and a control mechanism 6, both of which are installed on the second support rod 302, the power supply mechanism 5 is electrically connected to the electric transmission component 2033, the electric hoist 102 and the control mechanism 6, respectively, and the control mechanism 6 is electrically connected to the electric transmission component 2033 and the electric hoist 102, respectively, to control the operation of the electric transmission component 2033 and the electric hoist 102.

[0062] The power supply mechanism 5 and the control mechanism 6 are respectively installed on both sides of the second support rod 302. The power supply mechanism 5 continuously supplies power to the electric transmission component 2033, the electric hoist 102 and the control mechanism 6, so that the electric transmission component 2033, the electric hoist 102 and the control mechanism 6 can work continuously. The control mechanism 6 controls the electric transmission component 2033 and the electric hoist 102 to start and end work.

[0063] The control mechanism 6 includes a controller 601 and a remote controller 602 . The remote controller 602 is in communication with the controller 601 . The controller 601 receives instructions from the remote controller 602 to control the operation of the electric transmission component 2033 and the electric hoist 102 .

[0064] The remote controller 602 can send instructions to the controller 601 remotely. After receiving the instructions, the controller 602 controls the relevant components to perform corresponding operations. The remote controller 602 sends the rail transport instruction to the controller 601 remotely. After receiving the instruction, the controller 602 controls the motor 2034 and the reducer 2035 to work. The motor 2036 starts to rotate. The reducer 2037 adjusts the speed of the motor 2036. With the cooperation of the gear 2038 and the chain 2039, the walking wheel body 2031 drives the support mechanism 3 and the lifting mechanism 1 to move toward the rail storage place. After arriving at the rail storage place, the remote controller 602 sends the rail lifting instruction. After receiving the instruction, the controller 601 controls the electric hoist 102 of the lifting mechanism 1 to move downward close to the rail. When the hook 103 of the electric hoist 102 contacts the rail, the hook 103 is fastened to the rail and the electric hoist 102 is used to lift the rail. The rail is hoisted; then the remote controller 602 sends a transport to the target location instruction. After the controller 601 receives the transport to the target location instruction, it continues to control the motor 2036 to rotate. With the cooperation of the reducer 2037, the gear 2038 and the chain 2039, the walking wheel body 2031 transports the rail to the target location. Then, the remote controller 602 sends an installation instruction. The controller 601 receives the installation instruction and controls the electric hoist 102 to slide left or right along the beam 101. The remote controller 602 can control the sliding distance of the electric hoist 102, whether to continue sliding, etc. When the electric hoist 102 drives the rail to slide along the beam 101 to the installation position, the hook 103 of the electric hoist 102 is controlled to move downward to install the rail to the target position. The controller 601 is a Siemens controller with model S7-1200.

[0065] like Figure 1 As shown, the support mechanism 3 also includes a first cross bar 305 and a second cross bar 306. The first cross bar 305 and the second cross bar 306 are both arranged in the middle of the length direction of the second support bar 302. The two ends of the first cross bar 305 are respectively connected to the first support bar 301 and the second support bar 302, and the two ends of the second cross bar 306 are respectively connected to the second support bar 302 and the third support bar 303.

[0066] The left and right sides of each second support rod 302 are fixedly connected with a first cross bar 305 and a second cross bar 306. The first cross bar 305 and the second cross bar 306 can make the connection between the first support rod 301 and the second support rod 302, and the connection between the second support rod 302 and the third support rod 303 more stable, thereby improving the safety of the rail laying device.

[0067] The power supply mechanism 5 is a rechargeable lithium battery.

[0068] When the rail laying device is not in use, the power supply mechanism 5 can be charged through an external power supply, so that when the rail laying device is working, the power supply mechanism 5 supplies power to the electric transmission component 2033, the electric hoist 102 and the control mechanism 6. Using a lithium battery as the power supply mechanism 5 to supply power to the electric transmission component 2033, the electric hoist 102 and the control mechanism 6 can achieve energy saving and environmental protection in the process of using electricity.

[0069] When in use, the position of the guide wheel body 2021 is adjusted according to the height of the prefabricated board 4, and the second rotating member 2025 is adjusted in the slide groove 2026 until the guide wheel body 2021 can slide along the prefabricated board 4. According to the on-site conditions of the track, the position of the walking wheel body 2031 is adjusted. Since the walking wheel body 2031 is installed at the end of the walking beam 201, the position of the walking wheel body 2031 can be adjusted by adjusting the position of the walking beam 201. The guide wheel body 2021 not only has a guiding function but also supports the walking beam 201. The length of the connecting member 2022 on the rear side of the guide wheel body 2021 is adjusted to achieve the purpose of adjusting the position of the walking wheel body 2031. Because the space on both sides of the road surface inside the track is limited, the walking wheel body 2031 may need to walk on a sloped inclined surface. Therefore, by adjusting the connection position of the second connecting plate 2035 and the adjusting slide 2034 on the first connecting plate 2032, the angle between the walking wheel body 2031 and the horizontal plane can be adjusted, so that the walking wheel body 2031 can walk smoothly in the track. After the rail laying device is adjusted, the rails can be transported from the rail storage to the target location and placed at the location to be installed through the cooperation of the remote controller 602, the controller 601, the motor 2036, the reducer 2037, the gear 2038, the chain 2039 and the electric hoist 102. This application solves the walking and span problems of the tire-type track laying machine in the subway station, making the laying of prefabricated slab track bed rails simpler, safer and more efficient. Through continuous improvement and improvement in the actual construction process, the rail laying device was successfully tested in Suzhou Rail Line 7. Compared with the traditional process, the efficiency is increased by 40%, and the labor force is greatly reduced, which effectively protects the safety of finished products and personnel, and has obvious advantages.
