Description

Technical Field

[0001] This utility model relates to track-laying train sets, and in particular to an energy-swapping vehicle. Background Technology

[0002] A rail laying unit typically includes a tractor, a pusher, and a flatcar. The tractor is located in front of the pusher, and the flatcar is located behind the pusher. The pusher is equipped with a rail feeding device, which pushes the rails on the flatcar through the pusher to the tractor, where the tractor pulls the rails to complete the laying.

[0003] Most pushcarts use internal combustion generators to power various electrical devices. This power supply method is not only highly polluting, but also has a conversion efficiency of only 30%-50% between chemical and electrical energy, easily leading to significant waste. To improve energy utilization, modern pushcarts use battery packs as the power source for their electrical equipment, thus increasing energy efficiency.

[0004] However, due to the presence of electrical equipment such as track-laying devices on the push vehicle, the space available for installing the battery box is relatively small. This results in the battery box having little power remaining after completing a single shift of track-laying and power supply, requiring timely recharging. The battery capacity has always been a factor restricting the widespread adoption of new energy push vehicles. Utility Model Content

[0036] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0037] like Figure 1-5As shown, an embodiment of this utility model provides an energy replacement vehicle for use in a track laying vehicle group. Specifically, the energy replacement vehicle 100 is located between the pusher vehicle 200 and the flatcar 300. The rail is moved from the flatcar 300 to the pusher vehicle 200 via the energy replacement vehicle 100 and is pushed out by the pusher vehicle 200, thereby being pulled by the traction vehicle to complete the laying of the rail.

[0038] Specifically, the energy replacement vehicle 100 includes a carrier 110 that can travel on rails. The head and tail (i.e., the length direction) of the carrier 110 are connected to the pusher 200 and the flat car 300, respectively, so that the energy replacement vehicle 100 moves synchronously with the pusher 200 and the flat car 300.

[0039] A mounting frame 120 is also provided on the carrier 110. The mounting frame 120 has a length direction and a width direction. A transition channel 121 is provided in the length direction of the mounting frame 120. The transition channel 121 is co-lined with the rail delivery channel of the pusher 200 and the rail transport channel of the flat car 300. A spare battery pack can also be detachably installed on the mounting frame 120.

[0040] The energy swapping vehicle 100 connects the flatcar 300 and the pushcar 200, ensuring that the rails can move from the flatcar 300 to the pushcar 200. When the pushcar 200 needs a battery swap, workers unlock the spare battery pack and use equipment such as cranes to move the spare battery pack to the battery pack location on the pushcar 200 to replace the depleted battery pack.

[0041] Furthermore, in this application, the mounting frame 120 is a frame structure, comprising a lower frame 123 and an upper frame 122. The lower frame 123 is fixed to the carrier 110, and the upper frame 122 is disposed on the lower frame 123 and can move relative to the lower frame 123 along the length of the lower frame 123. The aforementioned transition channel 121 is disposed on the lower frame 123 and is arranged along the length of the lower frame 123. The aforementioned backup battery pack is detachably fixed on the upper frame 122. In this embodiment, the backup battery pack and the battery pack have the same structure, both having a battery management system and a power supply socket electrically connected to the electrical equipment. The electrical equipment is electrically connected to the battery pack. The backup battery pack and the battery pack are detachably connected to the upper frame 122 and the pusher 200 using existing methods, such as using base components commonly used in containers and threaded turnlocks for connection.

[0042] In this embodiment, a mounting portion 122-1 is formed in the middle of the upper surface of the lower shelf 123. The mounting portion 122-1 is formed by a downward indentation from the upper surface of the lower shelf 123. The mounting portion 122-1 starts from one end of the lower shelf 123 near the pusher 200 and is provided along the length of the lower shelf 123. Correspondingly, a mating portion 123-1 is formed in the middle of the lower surface of the upper shelf 122. The mating portion 123-1 is formed by a downward protrusion from the lower surface of the upper shelf 122. The mating portion 123-1 is fitted into the mounting portion 122-1. A drive mechanism 125 is also provided between the mating portion 123-1 and the mounting portion 122-1. Under the action of the drive mechanism 125, the upper shelf 122 moves within the mounting portion 122-1 along the length direction of the mounting portion 122-1.

[0043] Since a spare battery pack is fixed on the upper shelf 122, the spare battery pack can move closer to the push vehicle 200 when the battery is being swapped, and move away from the push vehicle 200 when the battery is not being swapped.

[0044] Specifically, in the embodiments of this application, the drive mechanism 125 is disposed on the upper shelf 122. The drive mechanism 125 includes a drive motor 125-1 and a linear engagement unit 125-2. The drive motor 125-1 is fixed to the bottom of the upper shelf 122, and the linear engagement unit 125-2 is fixed inside the mounting part 122-1 and arranged along the length direction of the mounting part 122-1. A plurality of teeth are provided on the linear engagement unit 125-2, and the teeth are arranged along the length direction of the linear engagement unit 125-2.

[0045] A gear 152-3 is provided on the output shaft of the drive motor 125-1. The gear 152-3 can mesh with the meshing teeth, so that the rotational motion of the drive motor 125-1 is converted into the linear motion of the linear meshing unit 125-2, thereby causing relative sliding between the upper shelf 122 and the lower shelf 123.

[0046] In one embodiment of this application, when the linear meshing unit 125-2 is a rack, the gear 152-3 and the rack can be driven by meshing.

[0047] In another embodiment of this application, the linear meshing unit 125-2 includes two side plates arranged side by side, which are arranged along the length of the lower frame 123. A lever is arranged between the two side plates. The teeth of the gear 152-3 can mesh with the lever. When the gear 152-3 rotates, it meshes with the lever, thereby causing relative movement between the linear meshing unit 125-2 and the gear 152-3.

[0048] Preferably, in this application, two linear meshing units 125-2 are provided, arranged side by side along the width direction of the lower frame 123, and both linear meshing units 125-2 are located in the mounting part 122-1. The corresponding drive mechanism 125 also includes a dual-output shaft reducer, the drive motor 125-1 is connected to the input shaft of the dual-output shaft reducer, and a gear 152-3 is provided on each of the two output shafts of the dual-output shaft reducer, one gear 152-3 is hinged to one linear meshing unit 125-2, and the other gear 152-3 is hinged to the other linear meshing unit 125-2.

[0049] Furthermore, to reduce the frictional resistance between the upper shelf 122 and the lower shelf 123 during relative sliding, a guide groove 123-2 is provided on the lower shelf 123. This guide groove 123-2 extends along the length of the lower shelf 123, and two guide grooves 123-2 are provided in the width direction of the lower shelf 123. Corresponding to the guide grooves 123-2, guide wheels 122-2 are also provided on the upper shelf 122. Several guide wheels 122-2 are provided, and these are divided into two groups in the width direction of the upper shelf 122. The guide wheels 122-2 in each group are arranged along the length direction of the upper shelf 122. The guide wheel 122-2 is located in the guide groove 123-2. The guide wheel 122-2 serves as both a support and a rolling function, thereby converting the sliding friction between the upper shelf 122 and the lower shelf 123 into rolling friction between the guide wheel 122-2 and the lower shelf 123, making it easier for the upper shelf 122 and the lower shelf 123 to slide relative to each other.

[0050] Preferably, there are two transition channels 121, which are arranged along the width direction of the lower shelf 123. The mounting part 122-1 is located between the two transition channels 121, and the two transition channels 121 are located between the two guide grooves 123-2.

[0051] Preferably, an auxiliary guide roller group is provided in each transition channel 121, and several auxiliary guide roller groups are arranged along the length direction of the transition channel 121. Two auxiliary guide rollers 124 in each auxiliary guide roller group are arranged along the width direction or the height direction of the transition channel 121, thereby converting the sliding friction between the rail and the transition channel 121 into rolling friction.

[0052] Preferably, a guide unit 150 is provided at one end of each transition channel 121 near the flatcar 300. The guide unit 150 is used to guide the rail from the flatcar 300 into the transition channel 121.

[0053] In this embodiment, the guide unit 150 is a guide frame, which is in the shape of a truncated pyramid. The end of the guide frame with a larger cross-section faces the flatcar 300, and the end with a smaller cross-section faces the transition channel 121.

[0054] Preferably, the carrier 110 is provided with a coupler 140 for the pusher 200 and the flatcar 300 at the front and rear ends, respectively, to facilitate connection or disconnection with the pusher 200 and the flatcar 300.

[0055] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
