[0021] like Figure 1 As shown, an embodiment of the present invention provides a new energy track laying equipment set, including: The new energy rail tractor 100 includes a tractor body 101, a first battery pack 102, and a first lifting device 103. The first battery pack 102 is detachably mounted on the top of the tractor body 101 and is used to provide power to the new energy rail tractor 100. The new energy rail pusher 200 includes a pusher body 201, a second battery pack 202, and a second lifting device 203; the second battery pack 202 is detachably mounted on the top of the pusher body 201 and is used to provide power to the new energy rail pusher 200; The battery transport vehicle 300 includes a transport vehicle body 301 and a third lifting device 303; the transport vehicle body 301 is used to carry multiple replacement battery packs 302; Among them, the first lifting device 103 is installed on the tractor body 101, and is used to lift the first battery pack 102, and lift the replacement battery pack 302 unloaded from the transport vehicle body 301; the second lifting device 203 is installed on the push vehicle body 201, and is used to lift the second battery pack 202, and lift the replacement battery pack 302 on the transport vehicle body 301 off the transport vehicle body 301; the third lifting device 303 is installed on the transport vehicle body 301, and is used to lift the first battery pack 102 or the replacement battery pack 302 unloaded from the new energy rail tractor 100 to the transport vehicle body 301, and lift the second battery pack 202 or the replacement battery pack 302 unloaded from the new energy rail push vehicle 200 to the transport vehicle body 301.

[0022] Specifically, when the new energy rail tractor 100 is working, the long rail can be pulled to the predetermined laying position by the rail clamping device to achieve the laying of the rail. Figure 2 As shown, compared to traditional rail tractors using internal combustion engines, the new energy rail tractor 100 of this embodiment is equipped with a first battery pack 102 on its roof and powered by the first battery pack 102. This allows it to better adapt to the low pressure, high cold, thin air, and poor air circulation in tunnels brought about by the plateau environment. At the same time, the new energy rail tractor 100 of this embodiment does not produce exhaust gas during operation, which not only solves the problem of environmental pollution but also greatly reduces the safety of workers in tunnels. At the same time, a first lifting device 103 is installed on the roof of the new energy rail tractor 100, which can be used to lift the battery pack.

[0023] When the new energy rail pusher 200 is working, it can push the long rails from the transport vehicle to the laying position to prepare for the subsequent traction operation. Figure 3As shown, compared with the traditional rail pusher using an internal combustion engine, the new energy rail pusher 200 of this embodiment is provided with a second battery pack 202 on the roof and is powered by the second battery pack 202. It can also better adapt to the low pressure and high cold, thin air, and poor air circulation in the tunnel brought about by the plateau environment. At the same time, the new energy rail pusher 200 of this embodiment also does not produce exhaust gas when working, which not only solves the problem of environmental pollution, but also greatly reduces the safety of workers in the tunnel. At the same time, the roof of the new energy rail pusher 200 is equipped with a second lifting device 203, which can be used to lift the battery pack.

[0024] When the battery transport vehicle 300 is working, it can be used to carry replacement battery packs 302. Figure 4 As shown, the battery transport vehicle 300 includes a transport vehicle body 301 and a third lifting device 303; the top of the transport vehicle body 301 is used to carry multiple replacement battery packs 302, and the top of the transport vehicle body 301 is also equipped with a third lifting device 303, which can be used to lift the battery packs.

[0025] In this optional embodiment, a first battery pack 102 is detachably mounted on the top of the tractor body 101 of the new energy rail tractor 100, and a second battery pack 202 is detachably mounted on the top of the pusher body 201 of the new energy rail pusher 200. Compared with the battery pack being arranged under the body, the space around the battery packs of both becomes larger, which can effectively reduce the difficulty of battery replacement, thereby reducing the time for battery replacement and improving construction efficiency; the transport vehicle body 301 of the battery transport vehicle 300 is used to carry multiple replacement battery packs 302, which can provide replacement batteries for the new energy rail tractor 100 and the new energy rail pusher 200. In this way, when performing track laying operations in a one-way tunnel, the new energy rail tractor 100 and the new energy rail pusher 200 do not need to exit the tunnel to replace the battery, thereby reducing the time for battery replacement and improving construction efficiency; at the same time, the new energy rail tractor 100, the new energy rail pusher 200 and the battery transport vehicle 300 are respectively provided with a first lifting device. Device 103, a second lifting device 203 and a third lifting device 303, wherein the first lifting device 103 is used to lift the first battery pack 102 and lift the replacement battery pack 302 unloaded from the transport vehicle body 301; the second lifting device 203 is used to lift the second battery pack 202 and lift the replacement battery pack 302 on the transport vehicle body 301 off the transport vehicle body 301; the third lifting device 303 is used to lift the first battery pack 102 or the replacement battery pack 302 unloaded from the new energy rail tractor 100 to the transport vehicle body 301, and lift the second battery pack 202 or the replacement battery pack 302 unloaded from the new energy rail pusher 200 to the transport vehicle body 301. Therefore, when replacing the batteries of the new energy rail tractor 100 and the new energy rail pusher 200, compared with manual handling of the batteries, the difficulty of battery replacement is further reduced, thereby reducing the time for battery replacement, and further realizing uninterrupted construction of the new energy track laying equipment to improve construction efficiency.

[0026] Optionally, the first battery pack 102 , the second battery pack 202 and the replacement battery pack 302 all include a temperature control module 400 and a thermal management device 500 electrically connected to the temperature control module 400 , and the temperature control module 400 is used to monitor the battery pack temperature and control the operation of the thermal management device 500 .

[0027] Specifically, the first battery pack 102, the second battery pack 202 and the replacement battery pack 302 are all lithium iron phosphate battery packs, such as Figure 5As shown, all three include a temperature control module 400 and a thermal management device 500 electrically connected to the temperature control module 400. The temperature control module 400 includes a temperature sensor 401 and a controller 402. The temperature sensor 401 is used to monitor the temperature of the battery pack in real time and transmit the temperature data to the controller 402. The controller 402 is electrically connected to the temperature sensor 401 and the thermal management device 500, respectively. The controller 402 is used to determine whether to start or stop the thermal management device 500 based on a preset temperature threshold and temperature change rate.

[0028] like Figure 5 As shown, thermal management device 500 includes a heating film 501 and a cooling fan 502, each electrically connected to controller 402. Heating film 501 can quickly raise the temperature of the battery pack in low-temperature environments, improving the battery's low-temperature performance and preventing the decrease in charge and discharge efficiency and capacity decay caused by low temperatures, thereby extending battery life. Cooling fan 502, on the other hand, dissipates heat through forced convection in high-temperature environments, preventing battery performance degradation or thermal runaway caused by overheating and ensuring battery safety and stability under high-temperature conditions. This combined heating and cooling temperature control design not only optimizes the battery's charge and discharge performance, but also increases the reliability and service life of the battery pack under complex operating conditions.

[0029] Optionally, the transport vehicle body 301 is connected to the push vehicle body 201 , and the new energy rail push vehicle 200 is configured to drive the battery transport vehicle 300 to move.

[0030] Specifically, the transport vehicle body 301 is connected to the push vehicle body 201 via a mechanical connection device. In one embodiment, the mechanical connection device includes a detachable coupler and a connecting plate, wherein the coupler is mounted on the rear end of the push vehicle body 201 and the connecting plate is fixed to the front end of the transport vehicle body 301.

[0031] In this optional embodiment, the transport vehicle body 301 and the push vehicle body 201 are connected by connecting the coupler and the connecting plate, thereby achieving a stable connection between the tractor and the transport vehicle. The power generated by the drive system of the new energy rail push vehicle 200 is transmitted to the battery transport vehicle 300 via the coupler and the connecting plate, thereby driving the battery transport vehicle 300 to move.

[0032] It should be understood that, although the above description describes that the battery transport vehicle 300 is driven by the new energy rail push vehicle 200, the battery transport vehicle 300 itself can also be equipped with a walking drive system to achieve walking.

[0033] Optionally, the first lifting device 103, the second lifting device 203 and the third lifting device 303 are all rotatable cantilever cranes.

[0034] Specifically, the cantilever crane includes a fixed base, a rotatable cantilever and a lifting mechanism. The fixed base is used to firmly install the cantilever crane. The rotatable cantilever can achieve 360° horizontal rotation and achieve smooth operation through a motor drive and gear transmission system. The lifting mechanism is equipped with a hook, wire rope and winch, and has sufficient lifting capacity to meet the lifting needs of goods of different weights.

[0035] Optionally, the battery transport vehicle 300 further includes a pushing device 305 and a battery conveying bracket 304; a plurality of replacement battery packs 302 are arranged in sequence along the length direction of the battery transport vehicle 300 and are all slidingly connected to the battery conveying bracket 304; the pushing device 305 is configured to drive the replacement battery to move along the battery conveying bracket 304.

[0036] Specifically, if Figure 4 As shown, there are multiple replacement battery packs 302, and the multiple replacement battery packs 302 are adjacent to each other along the length direction of the battery transport vehicle 300, and the multiple replacement battery packs 302 are all slidingly connected to the battery conveying bracket 304; the pushing device 305 is a telescopic cylinder, which drives the last fully charged replacement battery pack 302 (that is, the replacement battery pack 302 farthest from the new energy rail pushing vehicle 200) to slide relative to the battery conveying bracket 304, and can drive the remaining fully charged replacement battery packs 302 to move on the battery conveying bracket 304, so that the replacement battery packs 302 are transported to the lifting position of the battery transport vehicle 300.

[0037] In this optional embodiment, after the replacement battery pack 302 at the lifting position of the battery transport vehicle 300 is lifted by the second lifting device 203, the pushing device 305 is started. The pushing device 305 can push the next replacement battery pack 302 to the lifting position of the battery transport vehicle 300 for subsequent lifting work by the second lifting device 203.

[0038] Alternatively, as Figure 6 As shown, the new energy track laying equipment also includes a lifting fitting 600 for cooperating with lifting; the first battery pack 102, the second battery pack 202 and the replacement battery pack 302 are all connected to the lifting fitting 600.

[0039] In this optional embodiment, on the one hand, the setting of the lifting fitting 600 significantly improves the efficiency of battery pack lifting and replacement, and reduces the complexity and time cost of manual operation; on the other hand, the structural design of the lifting fitting 600 ensures the safety and stability of the lifting process, effectively protects the battery pack from damage, and extends the service life of the battery pack.

[0040] In one embodiment, the lifting fitting 600 is a lifting lug, a lifting ring or a lifting hook.

[0041] In this embodiment, the lifting lugs, rings, or hooks are welded to the battery pack casing. This allows the battery pack to be quickly connected and disconnected from the lifting device during the lifting process, significantly improving the efficiency of battery pack replacement and transportation and reducing time delays caused by complex lifting operations. Furthermore, the simple and high-strength structure of the lifting lugs, rings, and hooks can withstand the tensile forces during lifting, ensuring the stability and safety of the battery pack during the lifting process and effectively preventing damage caused by improper lifting.

[0042] In another embodiment, the lifting fitting 600 includes a frame and a lifting ring fixedly connected to the frame, and the frame is configured to accommodate the first battery pack 102, the second battery pack 202 or the replacement battery pack 302.

[0043] In this embodiment, the combination of the frame and lifting rings provides a stable and reliable lifting structure for the battery pack, effectively distributing the forces during lifting and avoiding damage caused by localized stress concentration. Furthermore, the frame's containment function ensures the stability of the battery pack during lifting, preventing it from shaking or shifting, thereby improving the safety and reliability of the lifting process.

[0044] Optionally, the materials of the push vehicle body 201, the tractor vehicle body 101 and the transport vehicle body 301 are all Q355E, Q420E or Q460E.

[0045] In this embodiment, the material exhibits high strength and low-temperature toughness, making it suitable for the cold climate of plateau regions and reducing the risk of brittle fracture caused by low temperatures, thereby ensuring the safety and reliability of the vehicle structure under extreme conditions. Furthermore, its excellent welding and processing properties facilitate vehicle manufacturing and maintenance.

[0046] The embodiment of the present invention provides a method for operating a new energy track laying equipment set, using the new energy track laying equipment set as described above, such as Figure 7 Shown, including: S100: When at least one of the new energy rail tractor 100 and the new energy rail pusher 200 issues a low battery alarm, controlling the new energy rail tractor 100 and the new energy rail pusher 200 to stop the track laying operation; S200: Perform battery replacement operations on the new energy rail pusher 200 and the new energy rail traction vehicle 100.

[0047] In step S100, when the battery of any one of the new energy rail pusher 200 and the new energy rail traction vehicle 100 needs to be replaced, the battery of the other device should be replaced at the same time.

[0048] In step S200, when the battery replacement operation is performed on the new energy rail pushing vehicle 200 and the new energy rail traction vehicle 100, the battery of one of the two is replaced first, and then the battery of the other is replaced. For example, the battery of the new energy rail pushing vehicle 200 can be replaced first, and then the battery of the new energy rail traction vehicle 100 can be replaced.

[0049] It should be understood that when the new energy track laying equipment is working, the new energy rail tractor 100, the new energy rail pusher 200, and the battery transporter 300 are distributed in sequence from front to back; the roller pushing device 305 and the guide frame of the new energy rail pusher 200 are used to smoothly deliver the front end of the rail into the rail clamping device of the new energy rail tractor 100, and the new energy rail tractor 100 drags the rail to the roadbed until the rail laying is completed.

[0050] Alternatively, as Figure 8 As shown, the battery replacement operation for the new energy rail pusher 200 includes the following steps: S210: disconnect one of the second battery packs 202 to be hoisted on the new energy rail pusher 200, and use the second hoisting device 203 on the new energy rail pusher 200 to hoist the disconnected second battery pack 202 to the ground for placement; S220: disconnect the replacement battery pack 302 to be lifted on the battery transport vehicle 300, control the second lifting device 203 to lift the replacement battery pack 302 to be lifted to the new energy rail push vehicle 200, and connect the replacement battery pack 302 on the new energy rail push vehicle 200; S230, repeat the above steps until all the second battery packs 202 on the new energy rail pusher 200 are replaced with the replacement battery pack 302; S240 : Control the third lifting device 303 on the battery transport vehicle 300 to lift the second battery pack 202 placed on the ground to the battery transport vehicle 300 for storage.

[0051] In this optional embodiment, since steps S210 and S220 respectively realize the unloading of the second battery pack 202 and the loading of the replacement battery pack 302, and both are completed by the second lifting device 203, this mechanized operation significantly reduces manual intervention, reduces labor intensity and operational risks. At the same time, step S230 can systematically complete the replacement of all second battery packs 202 by repeating steps S210 and S220, ensuring the efficiency and consistency of the replacement process. In addition, step S240 recycles the replaced second battery pack 202 to the battery transport vehicle 300 for storage, realizing the recycling and centralized management of the battery pack. Therefore, from the perspective of the overall process, this method not only improves the efficiency of battery pack replacement, but also optimizes resource utilization, reduces equipment downtime, and thus improves battery replacement time.

[0052] Alternatively, as Figure 9 As shown, the battery replacement operation for the new energy rail tractor 100 includes the following steps: S310: Disconnect the corresponding number of replacement battery packs 302 on the battery transport vehicle 300 based on the number of first battery packs 102 to be replaced on the new energy rail traction vehicle 100, and control the second lifting device 203 on the new energy rail push vehicle 200 to lift the disconnected replacement battery packs 302 to the ground for placement; S320: Control the battery transport vehicle 300, the new energy rail push vehicle 200, and the new energy rail tractor 100 to move backward until the new energy rail tractor 100 moves to the replacement battery pack 302 placed on the ground; disconnect one of the first battery packs 102 to be hoisted on the new energy rail tractor 100, and use the first hoisting device 103 on the new energy rail tractor 100 to hoist the disconnected first battery pack 102 to the ground for placement; S330: Control the first lifting device 103 to lift the replacement battery pack 302 to be lifted on the ground to the new energy rail tractor 100, and connect the replacement battery pack 302 on the new energy rail tractor 100; S340, repeat the above steps until all the first battery packs 102 on the new energy rail tractor 100 are replaced with the replacement battery pack 302; S350 : Control the third lifting device 303 to lift the first battery pack 102 placed on the ground to the battery transport vehicle 300 for storage.

[0053] In this optional embodiment, first, step S310 pre-disconnects the corresponding number of replacement battery packs 302 on the battery transport vehicle 300 according to the number of first battery packs 102 to be replaced on the new energy rail tractor 100, and hoisted them to the ground for placement. This operation embodies a high degree of planning and coordination. By accurately matching the number of battery packs to be replaced, unnecessary operations and waiting time are avoided, thereby improving the efficiency of the entire replacement process. Then, step S320 controls the backward movement of each vehicle to accurately move the new energy rail tractor 100 to the side of the replacement battery pack 302. This coordinated movement strategy reduces the impact of space limitations on operations, and at the same time, by disconnecting and hoisting the first battery pack 102 to the ground, it creates conditions for subsequent replacement operations. This step-by-step operation ensures the orderliness and safety of the replacement process, and avoids delays caused by improper vehicle positioning or operational conflicts. In step S330, the first lifting device 103 on the new energy rail tractor 100 is used to lift the replacement battery pack 302 to the new energy rail tractor 100 and complete the connection. This process directly addresses the battery replacement needs of the core equipment (the new energy rail tractor 100), ensuring that the equipment can quickly resume operational capabilities. This efficient replacement operation reduces equipment downtime, improving equipment availability and operational efficiency. In step S340, by repeating the above steps, all first battery packs 102 on the new energy rail tractor 100 are replaced in batches. This cyclic operation further optimizes the overall replacement process, ensuring efficient replacement of all battery packs while reducing duplication of work caused by single operational errors or omissions. Finally, in step S350, the replaced battery packs are recovered using the third lifting device 303 and stored on the battery transport vehicle 300, achieving battery pack recycling and centralized management. Therefore, from the overall process perspective, this method not only improves the efficiency of battery pack replacement, but also optimizes resource utilization, reduces equipment downtime, and thus increases battery replacement time.

[0054] It should be understood that during the battery replacement operation of the new energy rail push vehicle 200 and the new energy rail traction vehicle 100, when the battery transport vehicle 300 recovers the battery pack through the third lifting device 303, the recovered battery pack is arranged in sequence along the length direction of the battery transport vehicle 300 at the end of the queue of replacement battery packs 302.

[0055] Although the present invention is disclosed as above, the protection scope of the present invention is not limited thereto. Those skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention, and these changes and modifications will fall within the protection scope of the present invention.
