Abstract
Description
Technical Field
[0001] This utility model relates to the field of track construction and transportation technology, and in particular to a transportation device that can travel between two ballastless tracks. Background Technology
[0002] Ballastless track refers to a track structure that uses an integral foundation of concrete, asphalt mixture, etc., instead of loose gravel track bed. It is also known as ballastless track and is the most advanced track technology in the world today.
[0003] On tracks where ballastless track slabs have been installed, if a track slab with a damaged base plate or a size that does not meet the requirements needs to be replaced, it is not possible to transport the track slabs by vehicle under the existing construction conditions. If manual handling is used, the track slabs are too heavy for manual transport. Hoisting is a common transportation method, but it is not possible to use hoisting to transport them to the construction site in some tunnel lines. Utility Model Content
[0004] To address the issue that, under existing technologies, it is impossible to transport track slabs by vehicle or by manpower when transporting track slabs on ballastless track, and that hoisting is a common transportation method, but it is not feasible to use hoisting to transport track slabs to construction sites in some tunnel sections, this application provides a transportation device that can travel between two lines of ballastless track, as detailed below.
[0005] A transport device capable of moving between two lines of ballastless track includes a support frame and a movable frame. A transport platform is fixedly mounted on the support frame, and the movable frame is located below the support frame. The movable frame and the support frame are detachably connected. The transport platform is used to place track slabs. Multiple solid tires are provided at both ends of the movable frame, and the solid tires are rotatably connected to the movable frame. The dimensions of the support frame and the movable frame are set to correspond to the dimensions between the two lines of the ballastless track.
[0006] By adopting the above technical solution, track slabs can be placed on the transport platform. The device can move using solid tires by pulling the mobile frame, allowing it to move between the two lines of the ballastless track. By connecting a power supply device, track slabs can be conveniently transported on the ballastless track, and can also be transported within the track, improving construction convenience. The solid tires effectively avoid vibration and impact during travel, ensuring that the track slabs on the transport platform are not damaged.
[0007] Optionally, the support frame includes multiple crossbeams and longitudinal beams. The crossbeams have the same length and shape and are arranged parallel to each other on the same horizontal plane. The longitudinal beams have the same length and shape and are arranged parallel to each other on the same horizontal plane. The crossbeams and longitudinal beams are arranged perpendicular to each other. The crossbeams are located on the upper side of the longitudinal beams. The upper side of the crossbeams is welded to the transport platform, and the lower side of the crossbeams is welded to the longitudinal beams.
[0008] By adopting the above technical solutions, the structural design of the crossbeams and longitudinal beams enables the support frame to have high stability and load-bearing capacity, effectively supporting the transportation platform and its track slabs. At the same time, the welding connection between the crossbeams and longitudinal beams is simple and easy to implement, with low production costs and easy promotion.
[0009] Optionally, the mobile frame includes an axle and a connecting channel steel. The axle is arranged along the length of the crossbeam and is detachably connected to the longitudinal beam. The connecting channel steel is arranged between the axles, and both ends of the connecting channel steel are detachably connected to the axles. The solid tire is rotatably connected to the axle.
[0010] By adopting the above technical solutions, the combined structure of the axle and connecting channel steel not only improves the overall rigidity of the device, but also facilitates disassembly and maintenance, thereby reducing the cost of use and extending the service life.
[0011] Optionally, a plurality of double-I-beam connectors are provided between the axle and the longitudinal beam. Each double-I-beam connector is welded together from two I-beams. The lower side of the double-I-beam connector is bolted to the axle, and the upper side of the double-I-beam connector is bolted to the longitudinal beam.
[0012] By adopting the above technical solutions, the double-I-beam connector makes the connection between the axle and the longitudinal beam more stable and reliable, improving the structural strength and stability of the entire transport device. At the same time, the upper and lower sides of the double-I-beam connector are connected by bolts, facilitating the quick assembly and disassembly of the axle and longitudinal beam, thus improving the ease and flexibility of maintenance for the transport device.
[0013] Optionally, the axle includes a double-web I-beam, the upper flange of which is used to be bolted to the double-jointed I-beam connector, and the lower flange of which is used to install a solid tire and a connecting channel steel.
[0014] By adopting the above technical solutions, the double-web I-beam design gives the axle higher strength and rigidity, enabling it to better withstand heavy loads on the transport platform. The double-web I-beam also facilitates the installation of solid tires and connecting channel steel, improving the structural stability and ease of installation of the entire transport device, making it easier to promote.
[0015] Optionally, both ends of the double-web I-beam are provided with reserved connection holes, which are used to attach a power device.
[0016] By adopting the above technical solution, the reserved connection hole can be conveniently attached to the power unit. When it is necessary to transport the power unit, it is easier to connect the power unit to the device through components such as hooks, which further improves convenience.
[0017] Optionally, a tire connecting steel pipe is welded to the bottom flange of the double-web I-beam, and the solid tire is rotatably connected to the tire connecting steel pipe.
[0018] By adopting the above technical solutions, the setting of the tire connecting steel pipe facilitates both manufacturing and installation of solid tires, ensuring that the solid tires can rotate smoothly. At the same time, it enhances the strength and durability of the structure, enabling the transport device to travel smoothly between the two lines of the ballastless track, effectively reducing vibration and wear during operation.
[0019] Optionally, the longitudinal beam and the double-web I-beam are each provided with two corresponding ones at the bottom. A solid tire is provided on both sides of the tire connecting steel pipe, and an axle is provided between the corresponding solid tires. Both ends of the axle are fixedly connected to the solid tires, and the axle is rotatably connected inside the tire connecting steel pipe.
[0020] By adopting the above technical solution, a solid tire is installed on each side of the tire connecting steel pipe, making the load distribution on each axle more even. A total of eight solid tires improve the stability of the ride. Axles are installed between the solid tires, with both ends of the axles fixedly connected to the solid tires and rotatably connected inside the tire connecting steel pipe. This design not only ensures the stability of the solid tires but also reduces friction, making the transport device move more smoothly and efficiently between the two ballastless track lines.
[0021] In summary, this application has at least the following beneficial effects:
[0022] This application solves the problem in existing technologies where transporting track slabs on ballastless track slabs is impossible using vehicles or manual labor. While hoisting is a common method, it's not feasible in some tunnel sections. This device, pulled manually or by a power unit, allows track slabs to be transported between two lines of ballastless track. Furthermore, the device is low-cost, simple to manufacture, and not limited by the number of machines. For simultaneous construction on multiple routes, simply increasing the number of transport vehicles and drivers is sufficient to meet on-site needs, facilitating widespread application. The device is also detachable for transport, allowing for reuse across multiple construction sites. Attached Figure Description

[0028] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0029] A transport device capable of traveling between two tracks on a ballastless track, such as Figure 1 and Figure 2 As shown, the device includes a support frame and a movable frame. A transport platform 9 is fixedly mounted on the support frame, and the movable frame is located below the support frame. The movable frame and the support frame are detachably connected. The transport platform 9 is used to place the track slab. Multiple solid tires 4 are installed at both ends of the movable frame, and the solid tires 4 are rotatably connected to the movable frame. The dimensions of the support frame and the movable frame correspond to the dimensions between the two lines of the ballastless track. In practice, during transportation, the support frame and the movable frame are first moved to the space between the two lines of the ballastless track for assembly. Then, the device can be pulled for transportation. After transportation, the entire device can be disassembled and then moved to its destination.
[0030] like Figure 1 and Figure 2 As shown, the support frame includes multiple crossbeams 2 and longitudinal beams 1. The crossbeams 2 are of the same length and shape and are arranged parallel to each other on the same horizontal plane. The longitudinal beams 1 are of the same length and shape and are arranged parallel to each other on the same horizontal plane. The crossbeams 2 and longitudinal beams 1 are arranged perpendicular to each other. The crossbeams 2 are located on the upper side of the longitudinal beams 1. The upper side of the crossbeams 2 is welded to the transport platform 9, and the lower side of the crossbeams 2 is welded to the longitudinal beams 1. In specific implementation, two crossbeams 2 are arranged in this embodiment, stacked along the axis of the width direction of the transport platform 9. Five longitudinal beams 1 are arranged. The five crossbeams 2 are arranged at equal intervals, with the third crossbeam 2 located on the axis of the length direction of the transport platform 9. The crossbeams 2 and longitudinal beams 1 arranged in a crisscross pattern can provide a strong supporting effect.
[0031] like Figure 1 and Figure 2 As shown, the mobile frame includes an axle and a connecting channel steel 7. The axle is arranged along the length of the crossbeam 2 and is detachably connected to the longitudinal beam 1. The connecting channel steel 7 is arranged between the axles, and both ends of the connecting channel steel 7 are detachably connected to the axles. The solid tire 4 is rotatably connected to the axle. In practical implementation, the solid tire 4 does not use cord as a frame and does not need to be inflated, thus exhibiting good durability under high load conditions.
[0032] like Figure 2 and Figure 3 As shown, multiple double-I-beam connectors 8 are installed between the axle and the longitudinal beam 1. Each double-I-beam connector 8 is formed by welding two I-beams together. The lower side of the double-I-beam connector 8 is bolted to the axle, and the upper side is bolted to the longitudinal beam 1. In practice, the double-I-beam connector 8 is formed by welding two I-beams of the same shape, which provides better rigidity and structural strength.
[0033] like Figure 2 and Figure 3 As shown, the axle includes a double-web H-beam. The upper flange of the double-web H-beam is used to connect with the double-jointed H-beam connector 8 by bolts, while the lower flange of the double-web H-beam is used to install the solid tire 4 and the connecting channel steel 7. In specific implementation, the double-web H-beam has two webs compared to a regular H-beam.
[0034] like Figure 1 and Figure 2 As shown, both ends of the double-web I-beam are provided with pre-drilled connection holes 6, which are used to attach a power device. In practice, the power device can be attached to the pre-drilled connection holes 6 using hooks or other equipment, and the device can be moved by pulling.
[0035] like Figure 2 and Figure 3 As shown, a tire connecting steel pipe 5 is welded to the bottom flange of the double-web I-beam, and a solid tire 4 is rotatably connected to the tire connecting steel pipe 5.
[0036] like Figure 1 and Figure 3 As shown, the longitudinal beam 1 and the double-web I-beam each have two solid tires at their bottom, arranged in a one-to-one correspondence. A solid tire 4 is installed on each side of the tire connecting steel pipe 5, and an axle 3 is installed between the corresponding solid tires 4. Both ends of the axle 3 are fixedly connected to the solid tire 4, and the axle 3 is rotatably connected inside the tire connecting steel pipe 5. In specific implementation, this embodiment uses a total of eight solid tires 4, which enables more stable transportation of the track slab.
[0037] Working principle: This device can be installed by simply welding or bolting multiple steel components. Except for the components that need to be welded, all components can be assembled between ballastless tracks. After assembly, it can be transported along the ballastless tracks.
[0038] The above are preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape and principle of this application should be covered within the scope of protection of this application.
