Description

Technical Field

[0001] This utility model relates to the field of track laying equipment, and in particular to a battery replacement system. Background Technology

[0002] Currently, during the rail laying process, tractor and pusher vehicles often use internal combustion generators to power the electrical equipment on the vehicle. However, internal combustion generators use diesel as the main fuel, which generates a lot of pollution during combustion. Moreover, diesel, as a combustible material, has high requirements for storage.

[0003] Due to the limitations of fuel, existing tractor-trailers and pushers are attempting to use battery packs for power, which contain several lithium batteries. However, during the laying of long steel rails, the travel route is quite long, and the pusher also needs to carry other equipment. Therefore, the number of battery packs that can be carried on the pusher is limited, making it difficult to sustain a shift of operation. For this reason, existing technology typically involves connecting a flatcar to the rear of the pusher to hold a spare battery pack for replacing the battery pack on the pusher.

[0004] However, existing battery replacement systems with excessively high crossbeams often obstruct the passage of track-laying equipment such as push vehicles through tunnels and other environments, while systems that are too low make it difficult to replace battery boxes. Utility Model Content

[0005] This invention provides a battery placement system, the purpose of which is to solve the problem that the height of the existing battery replacement system is inconvenient to adjust.

[0006] To achieve the above objectives, embodiments of this utility model provide a battery replacement system, comprising:

[0032] A-Battery box, B-Spare battery box Detailed Implementation

[0033] 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.

[0034] like Figure 1-4As shown, an embodiment of this utility model provides a battery replacement system for replacing the spare battery box B on the flatcar with the battery box A on the pushcart. Specifically, the battery replacement system includes a gantry crane 100 and an overhead crane 200. The gantry crane 100 is mounted on a carrier, such as a flatcar or a pushcart. The gantry crane 100 includes side columns 110 and crossbeams 120. The aforementioned side columns 110 are respectively installed at both ends of each crossbeam 120. Each side column 110 includes a first telescopic arm 111, a second telescopic arm 112, and a third telescopic arm 113. The lower end of the first telescopic arm 111 is used to stand upright on the carrier, i.e., fixed on the flatcar or pushcart. The second telescopic arm 112 is sleeved inside the first telescopic arm 111 and can move along the height direction of the first telescopic arm 111 within the first telescopic arm 111. The third telescopic arm 113 is sleeved inside the second telescopic arm 112 and can move along the height direction of the second telescopic arm 112 within the second telescopic arm 112.

[0035] A first telescopic component 114 is also provided on the first telescopic arm 111. The first telescopic component 114 is used to drive the second telescopic arm 112 to move relative to the first telescopic arm 111. A second telescopic component 115 is also provided on the second telescopic arm 112. The second telescopic component 115 is used to drive the third telescopic arm 113 to move relative to the second telescopic arm 112.

[0036] In this application, the side pillar 110 may include three telescopic arms, and the three telescopic arms can slide relative to each other, thus causing the height of the side pillar 110 to change. It can be adaptively adjusted according to different usage scenarios. For example, when encountering tunnels or other scenarios with height restrictions, the height of the side pillar 110 can be lowered to avoid collision between the battery replacement system and the tunnel. When it is necessary to replace the battery, the height of the side pillar 110 can be appropriately raised to avoid affecting the replacement of battery box A and spare battery box B.

[0037] Furthermore, in this application, a support ring 116 is provided on the second telescopic arm 112, the fixed end of the first telescopic component 114 is provided on the first telescopic arm 111, the movable end of the second telescopic component 115 is hinged to the support ring 116, the fixed end of the second telescopic component 115 is provided on the support ring 116, and the movable end of the second telescopic component 115 is hinged to the third telescopic arm 113.

[0038] Preferably, in this embodiment, the support ring 116 is sleeved on the top end of the second telescopic arm 112.

[0039] Furthermore, a first limiting hole 117 is provided at the upper part of the first telescopic arm 111, and a second limiting hole is provided at the bottom of the second telescopic arm 112. When the first limiting hole 117 and the second limiting hole coincide, a first limiting pin is inserted. The first limiting pin limits the maximum height of the first telescopic arm 111 and the second telescopic arm 112 by limiting the position of the first limiting hole 117 and the second limiting hole.

[0040] The top of the second telescopic arm 112 is provided with a third limiting hole 118, and the bottom of the third telescopic arm 113 is provided with a fourth limiting hole. When the third limiting hole 118 and the fourth limiting hole coincide, a second limiting pin is inserted. The second limiting pin limits the maximum height of the first telescopic arm 111 and the second telescopic arm 112 by limiting the position of the third limiting hole 118 and the fourth limiting hole.

[0041] The aforementioned crossbeam 120 is located at the top of the two third telescopic arms 113.

[0042] In this application, both the first telescopic assembly 114 and the second telescopic assembly 115 are linear actuators. These linear actuators can move the third telescopic arm 113 relative to the second telescopic arm 112, and the second telescopic arm 112 relative to the first telescopic arm 111, along a straight line. Common linear actuators include hydraulic cylinders, pneumatic cylinders, and linear modules. Preferably, the first telescopic assembly 114 and the second telescopic assembly 115 are arranged symmetrically about the axial center of the side post 110.

[0043] Furthermore, the gantry crane 100 also includes a main beam 130, with the aforementioned two crossbeams 120 arranged along the length of the main beam 130, and the two crossbeams 120 and the main beam 130 are orthogonal to each other. A crane 200 is also installed on the main beam 130, and the crane 200 travels along the length of the main beam 130. The crane 200 is used to lift battery box A or spare battery box B.

[0044] Specifically, the aforementioned overhead crane 200 includes an overhead crane base plate 210 and overhead crane side plates 220 disposed on both sides of the overhead crane base plate 210. A traveling wheel 230 is also disposed on the facing side of the two overhead crane side plates 220, and a drive mechanism 240 is disposed on the overhead crane base plate 210.

[0045] Traveling grooves are provided on both sides of the main beam 130, with the length direction of the traveling grooves aligned with the length direction of the main beam 130. Limiting protrusions are formed at both ends of the traveling grooves along the length direction. Traveling wheels 230 are located within the traveling grooves, and the drive mechanism 240 drives the overhead crane 200 to make the traveling wheels 230 roll within the traveling grooves. When the traveling wheels 230 move to the limiting protrusions, they cannot continue to move in that direction.

[0046] Preferably, the length of the running track is greater than the length of the vehicle, so that the travel length of the overhead crane 200 is greater than the length of the vehicle.

[0047] In this embodiment, each crane side plate 220 is provided with at least two traveling wheels 230. Multiple traveling wheels 230 are arranged along the length direction on the crane side plate 220. The provision of multiple traveling wheels 230 on each crane side plate 220 can ensure that the crane 200 remains stable during travel and avoids shaking.

[0048] The aforementioned drive mechanism 240 includes a drive motor and a rack. The drive motor is mounted on the overhead crane base plate 210 and has forward and reverse rotation functions. The output end of the drive motor is equipped with a gear.

[0049] The rack is mounted on the main beam 130, and its length direction is aligned with that of the main beam 130. The length of the rack is equal to or slightly greater than the distance between the two limiting protrusions. The gear meshes with the rack, thereby converting the rotary motion of the drive motor into the linear motion of the overhead crane 200.

[0050] Preferably, a reducer is also provided at the output end of the drive motor, and the gear is mounted on the output shaft of the reducer, that is, the power of the drive motor is transmitted to the gear through the reducer.

[0051] Furthermore, lifting mechanisms 250 are also provided on both sides of the two overhead crane plates 200. In this application, the lifting mechanism 250 is a double-outlet electric hoist. The two double-outlet electric hoists can wind and reel in steel cables. A lifting plate 260 is provided at the outlet end of the two double-outlet electric hoists, that is, a lifting plate 260 is provided at the free end of the steel cable. The lifting and lowering of the lifting plate 260 is achieved by winding and reeling in the steel cable. A connector is provided on the lifting plate 260, which is used for detachable connection with battery box A or spare battery box B.

[0052] Battery box A or spare battery box B is secured to the carrier via a detachable assembly. At least two battery boxes A are detachably mounted on the pushcart, and at least one spare battery box B is detachably mounted on the flatcar. Battery box A or spare battery box B is equipped with a structure that detachably engages with a connecting member. Typically, the connecting member is a straight-handle rotary lock, and battery box A or spare battery box B has an intermediate corner piece. The detachable connection is achieved through the engagement of the straight-handle rotary lock and the intermediate corner piece.

[0053] Battery box A contains lithium batteries, which are managed by BMS. Multiple battery boxes A supply power to the electrical equipment one by one.

[0054] The battery replacement system is activated by manual observation of the BMS (Battery Management System). It begins operation when the batteries in multiple battery boxes A are nearly depleted. First, the second telescopic assembly 115 extends. When the second telescopic arm 112 and the third telescopic arm 113 reach their maximum height, the second limiting pin is inserted into the third limiting hole 118 and the fourth limiting hole. Subsequently, the first extension assembly extends. When the first telescopic arm 111 and the second telescopic arm 112 reach their maximum height, the first limiting pin is inserted into the first limiting hole 117 and the second limiting hole. If environmental constraints prevent the gantry crane 100 from reaching its maximum height, the first and second limiting pins may not be inserted.

[0055] Next, the overhead crane 200 moves to above battery box A, which is not receiving power and has almost no charge. The suspended platform 260 descends, and workers connect battery box A to the platform 260 using connectors. The platform 260 rises, and the overhead crane 200 moves it above the flatcar, lowering battery box A. Workers then secure battery box A to the flatcar. Subsequently, the overhead crane 200 uses the same method to lift a fully charged spare battery box B onto the pushcart and secure it there. The electrical equipment on the pushcart is then electrically connected to the fully charged spare equipment to supply power. The remaining battery boxes A and spare battery boxes B are then lifted alternately.

[0056] Finally, the first limit pin is pulled out, the first telescopic component 114 retracts, and the second telescopic arm 112 descends. When it descends to the lowest height, the second limit pin is pulled out, the second telescopic component 115 retracts, and the third telescopic arm 113 descends to the lowest height, completing the battery swap.

[0057] 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.
