Description

Technical Field

[0001] This invention relates to the field of railway engineering machinery technology, and in particular to a new type of rail transport flatcar. Background Technology

[0002] With the rapid development of urban infrastructure, more and more cities are starting to build subway rail transit. Due to the limitations of the shield size, the construction space inside the subway is small. In the process of subway construction, track laying is the most important process and also the most labor-intensive part. The efficiency of subway track laying often directly affects the time of subway opening. Therefore, rail transport flatcars are used to transport the rails and increase the speed of rail laying.

[0003] As illustrated in the prior art patent application CN113335316A, this invention utilizes a rail-carrying flatcar for subway construction. The flatcar is horizontally positioned within a tunnel along its length. A car body, mounted on the track, includes a horizontally positioned mounting plate and a top plate. A traveling mechanism is located beneath the car body, allowing it to move along the track's length. A sleeper-carrying mechanism is mounted on the car body at its top front end. A rail-carrying mechanism is also mounted on the car body, its length aligned with the track's length. A material-feeding mechanism is mounted on the rail-carrying mechanism. This invention, a rail-carrying flatcar for subway construction, can carry rails and sleepers along the track, transporting large quantities of sleepers and rails to the construction site. This increases the handling capacity, reduces manual labor intensity, avoids multiple handling operations, improves work efficiency, and enhances equipment usability.

[0004] However, this rail storage flatcar mainly relies on ordinary flatcars with roller beams to transport long steel rails. It cannot carry other operating devices, making it difficult to cooperate with vehicles such as rail unloading cars and rail collection cars. It cannot adapt to the construction occasions of subways that have requirements for the length and space of the entire vehicle. Furthermore, it cannot meet the needs for lateral and vertical position adjustment and longitudinal transportation during the overall transportation of steel rails.

[0005] Therefore, it is necessary to provide a new type of rail transport flatcar to solve the above-mentioned technical problems. Summary of the Invention

[0006] This invention provides a novel rail transport flatcar that solves the problems of not being able to carry other operating devices, being difficult to coordinate with rail unloading and rail collection vehicles, not being suitable for the overall length and space requirements of subway construction, and not being able to meet the horizontal, vertical and longitudinal adjustment needs of the overall rail transport.

[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0027] First Embodiment

[0028] Please refer to the following: Figure 1 , Figure 2 ,in, Figure 1 This is a schematic diagram of the structure of a first embodiment of a novel rail transport flatcar provided by the present invention; Figure 2 for Figure 1The diagram shows a top view of the structure. A novel rail transport flatcar includes: a frame 9, with hook and buffer devices 8 fixedly installed at both ends of the frame 9;

[0029] Two rail traverse devices 11 are fixedly installed at both ends of the top of the frame 9, and rail conveying devices 10 are provided on both sides of the two rail traverse devices 11.

[0030] Two rail storage platforms 12 are fixedly installed at both ends of the vehicle frame 9, respectively.

[0031] Two bogies 3 are respectively disposed at both ends of the bottom of the frame 9.

[0032] The rail storage platform 12 is located between the rail traversing device 11 and the rail conveying device 10.

[0033] The top two ends of the vehicle frame 9 are each fixedly installed with railings 2, and the two ends of the vehicle frame 9 are each fixedly installed with ladders 1.

[0034] The bottom of the frame 9 is respectively provided with a battery 4, an air braking system 5, a toolbox 6 and a handbrake 7. The air braking system 5 is located on the side of the battery 4, the toolbox 6 is located on the side of the air braking system 5, and the handbrake 7 is located on the side of the toolbox 6.

[0035] The vehicle features a ladder 1 for easy access to and from the flatcar; railings 2 ensure worker safety during vehicle operation; two bogies 3 for vehicle travel and steering; a battery 4 for powering the vehicle's electrical equipment; a toolbox 6 for storing tools and equipment used for vehicle operation and maintenance; an air brake system 5 for braking and releasing the vehicle during operation; a handbrake 7 for braking the vehicle during long-term parking or on slopes to prevent it from rolling away; a frame 9 for providing a reference and space, serving as the main body of the vehicle and mounting other devices; two sets of hook-and-response devices 8 for coupling flatcars together or with other vehicles for group operations; two rail storage platforms 12 for storing rails; two rail conveying devices 10 for longitudinally transporting rails while preventing them from tipping over during transport; and two sets of rail lateral movement devices 11 for lifting and lowering rails, adjusting their height, and moving them laterally to place them on the rail storage platform 12 or the rail conveying device 10.

[0036] The working principle of the novel rail transport flatcar provided by this invention is as follows:

[0037] In use, several car frames 9 are connected by a hook and buffer device 8 to form a rail transport vehicle capable of storing rails of the required length. The rail lateral movement device 11 is moved laterally to the middle position. When loading rails, the rails are transported to the designated position by the rail conveying device 10, and then the rails are lowered onto the rail lateral movement device 11. The rails are then lowered onto the rail storage platform 12 in sequence by the lateral movement of the rail lateral movement device 11. The rail transport vehicle and the tractor are assembled to transfer the rails to the designated working area.

[0038] When unloading the rails, the rail lateral movement device 11 moves laterally to push the rails stored on the rail storage platform 12 to the middle position in sequence, lifts the rails onto the rail conveying device 10, and longitudinally conveys the rails away from the rail transport vehicle; the rail conveying device 10 can adjust the height of the rails to keep them consistent with the working height of other vehicles (rail unloading vehicle, rail collection vehicle) to complete the rail unloading and rail collection operations.

[0039] Compared with related technologies, the novel rail transport flatcar provided by this invention has the following beneficial effects:

[0040] By cooperating with the frame 9 and the hook-and-response device 8, the hook-and-response device 8 can be connected to other vehicles during use, allowing for free grouping and coordination with other vehicles. This enables the rail transport flatcar to not only store rails but also cooperate with other vehicles to complete rail unloading and collection operations. Furthermore, the rail lateral movement device 11 and the rail conveying device 10 achieve overall smooth driving of the rails, with the transfer process being fully automated. The high degree of automation allows for stress-free overall positional changes of the rails, saving space while protecting the quality of the rails. This makes it suitable for working in confined construction environments such as subways.

[0041] Second Embodiment

[0042] Please refer to the following: Figure 3 , Figure 4 and Figure 5 Based on the novel rail transport flatcar provided in the first embodiment of this application, the second embodiment of this application proposes another novel rail transport flatcar. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0043] Specifically, the second embodiment of this application provides a novel rail transport flatcar that differs in that the rail storage platform 12 has multiple magnetic components 13 on its top. Each magnetic component 13 includes a fixed frame 131, a sliding rod 132, a spring 133, a connecting frame 134, a push switch 135, and an electromagnet 136. The electromagnet 136 is slidably connected to the inner side of the fixed frame 131, the connecting frame 134 is fixedly installed at the bottom of the electromagnet 136, the sliding rod 132 is slidably connected to the inside of the connecting frame 134, and the bottom of the sliding rod 132 is fixedly installed at the bottom of the inner side of the fixed frame 131. The spring 133 is sleeved on the outer side of the sliding rod 132, and the push switch 135 is fixedly installed at the bottom of the inner side of the fixed frame 131.

[0044] An extension rod 14 is fixedly installed at the bottom of the fixed frame 131, and a fixed rod 15 is slidably connected to the outer side of the extension rod 14. The bottom of the fixed rod 15 is fixedly installed on the top of the track storage platform 12.

[0045] The fixing rod 15 has an internal threaded connection to a locking screw 16 on its front side, and one end of the locking screw 16 abuts against the side of the extension rod 14.

[0046] The working principle of the novel rail transport flatcar provided by this invention is as follows:

[0047] When in use, the user places the rail on the rail storage platform 12. At this time, the bottom of the rail will press the electromagnet 136, which will cause the electromagnet 136 to move the connecting frame 134 downward. This will cause the bottom of the connecting frame 134 to press the top of the push switch 135. At this time, the electromagnet 136 can be activated by pressing the push switch 135, which will energize the electromagnet 136 and generate magnetic force, thereby magnetically attracting and limiting the rail.

[0048] When the rail needs to be removed, the worker lifts the rail using the rail lateral movement device 11. At this time, the spring 133 pushes the connecting frame 134 upward, so that the bottom of the connecting frame 134 moves away from the press switch 135, thereby stopping the electromagnet 136 from working and canceling the magnetic attraction to the rail.

[0049] Compared with related technologies, the novel rail transport flatcar provided by this invention has the following beneficial effects:

[0050] When the rail is placed on top of the electromagnet 136, the fixed magnet 136 can be energized to limit the rail, thereby preventing the rail from moving when the transport vehicle starts or brakes.

[0051] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
