Description

A 5G rail locomotive battery replacement and energy replenishment device for mining Technical Field

[0001] The present invention relates to the field of rail locomotive energy replenishment technology, and specifically discloses a 5G rail locomotive battery replacement and energy replenishment device for mining. Background Art

[0002] Traditional mining locomotives are primarily powered by internal combustion engines or electric motors. With the rapid development of new energy vehicles in my country, mining locomotives are also gradually transitioning to new energy sources. However, existing electric locomotives operate in harsh environments, making external batteries difficult to replace and replenish. Recharging is the only way to replenish batteries. However, mining locomotives require constant dispatching, necessitating the use of two locomotives for switching between them, increasing equipment costs.

[0003] Invention patent application number 2021114930928 discloses a hoist-mounted locomotive battery swap station, which includes a track for locomotive travel and parking; a battery placement area located to the side of the track; at least one replacement battery box for replacing the locomotive's battery box to be replaced; and battery swap equipment located above the battery placement area and the track for removing the locomotive's battery box to be replaced and transferring it outside the locomotive and track, and then grabbing the replacement battery box and transferring it to the locomotive. The hoist-mounted locomotive battery swap station disclosed in this invention patent has some shortcomings when used for battery swapping and energy replenishment for mining rail locomotives. First, for some current unmanned 5G rail locomotives, it is impossible to determine the battery level of the locomotive battery in a timely manner, resulting in the inability to perform battery replacement and energy replenishment in a timely manner; second, due to the large inertia of the mining locomotive during its travel on the track, it is impossible to accurately stop the locomotive at the position where the battery is to be replaced in a timely manner. Therefore, after the unmanned 5G rail locomotive stops, the operator needs to manually adjust its position to facilitate the subsequent grabbing and replacement of the battery. Therefore, in response to the shortcomings of the existing hoisting locomotive battery replacement station for mining locomotives, this application proposes a mining 5G rail locomotive battery replacement and energy replenishment device that can effectively solve the above technical problems. Summary of the Invention

[0004] The present invention aims to provide a battery replacement and energy replenishment device for a 5G rail locomotive for mining, so as to solve the shortcomings and technical problems existing in the existing hoisting locomotive battery replacement station when used for a 5G rail locomotive for mining.

[0005] The present invention is achieved through the following technical solutions:

[0006] A 5G rail locomotive battery replacement and energy replenishment device for mining includes a dispatching rack arranged perpendicular to the locomotive track, a battery pack storage chamber is provided at one end of the dispatching rack, a locomotive head is provided on the locomotive track, a battery pack grabbing mechanism is movably provided on the dispatching rack, a belt conveyor is provided at the discharge port of the battery pack storage chamber and is located directly below the dispatching rack, a control cabinet is provided next to the battery pack storage chamber, and a control module, a 5G wireless communication module and a satellite positioning module are provided inside the control cabinet;

[0007] The locomotive front includes a front body and wheels. The upper surface of the front body is provided with a battery packaging groove, and a battery pack is provided in the battery packaging groove. The rear end of the front body is provided with an electrical box, and the electrical box is provided with a control module, a 5G wireless communication module, a battery power detection module and a satellite positioning module.

[0008] As a further configuration of the above scheme, the dispatching rack includes support frames on both sides, the top ends of the support frames on both sides are fixedly connected to two parallel roller tracks, and the support frames are also provided with a traction device for realizing the movement of the battery pack grabbing mechanism along the roller tracks.

[0009] As a further configuration of the above scheme, the battery pack grasping mechanism includes a movable plate, the lower surface of the movable plate is provided with rollers matching the roller track, a lifting motor is provided on the movable plate, the lower end of the lifting motor is connected to a plate seat, clamping blocks are provided on both sides of the plate seat, and a driving component is provided on the plate seat to realize the clamping blocks on both sides approaching or moving away from each other.

[0010] As a further configuration of the above scheme, the driving assembly includes a bidirectional screw and a moving block, one end of the bidirectional screw is connected to a screw motor, the two moving blocks are respectively threadedly connected to the two ends of the bidirectional screw, both sides of the moving block are connected to movable rods, the two ends of the movable rods on the same side are commonly connected to a moving bar, and the outer side of the moving bar is connected to a clamping block through a moving rod.

[0011] As a further configuration of the above solution, the traction device includes a traction motor and a traction rope. A winding wheel is provided on the motor shaft of the traction motor, and both ends of the traction rope are respectively connected to the winding wheel and the movable plate.

[0012] As a further configuration of the above solution, a cover is rotatably connected to the upper surface of the vehicle head body located at the battery pack fitting groove, and a telescopic driving member for opening or closing the cover is also provided on the vehicle head body.

[0013] As a further arrangement of the above scheme, a pair of positioning wheels are provided at both ends of the upper surface of the locomotive body, and a vertical frame is provided on each side of the locomotive track in front of the dispatching frame. A hydraulic cylinder is provided at the upper end of the vertical frame, and each of the hydraulic cylinders is connected to a push positioning block at the movable end facing the locomotive track.

[0014] As a further configuration of the above solution, the gap between the two positioning wheels in each pair of the positioning wheels is set at 8-15 cm, and the push positioning block is in the shape of a triangle, with the tip of the triangle extending into the gap between the two positioning wheels.

[0015] The mining 5G rail locomotive battery replacement and energy replenishment device disclosed in the present invention is equipped with an electrical box in the locomotive head. The battery power detection module in the electrical box detects the battery pack power on the vehicle in real time. When the battery pack power is lower than the set value, the control module will send a signal to the control cabinet through the 5G wireless communication module.

[0016] After receiving the signal, the control cabinet issues the corresponding action command to start the traction device and battery pack grabbing mechanism, thereby moving the battery pack grabbing mechanism to directly above the position where the locomotive head stops for battery replacement and recharging. Satellite positioning modules are also installed in both the electrical box and the control cabinet. These modules determine the distance between the locomotive head and the battery replacement and recharging position in real time, then cause the locomotive head to begin braking at the set position, so that the locomotive head is directly below the battery pack grabbing mechanism when it stops.

[0017] Finally, start the battery pack grabbing mechanism again to first remove the battery pack on the locomotive head, then grab the fully charged battery pack sent out from the battery pack storage room, and directly load the fully charged battery pack into the locomotive head to complete the battery replacement and energy replenishment of the mining 5G rail locomotive.

[0018] In addition, the present invention further utilizes the interaction between the positioning wheels on both sides of the locomotive head and the positioning blocks on both sides of the locomotive track. After the locomotive head stops, the interaction between the beveled edges on both sides of the positioning blocks and the positioning wheels can make the entire locomotive head move slightly along the locomotive track, so that the battery pack mounting groove on the locomotive body is exactly aligned with the battery pack grabbing mechanism, ensuring the smooth subsequent grabbing and replacement of the battery pack.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] The 5G rail locomotive battery replacement and energy replenishment device for mining disclosed in the present invention can detect the battery power of the on-board battery pack in real time through the battery power detection module during the unmanned driving of the rail locomotive, and then use the 5G wireless transmission effect to enable the battery pack grasping mechanism to start corresponding action before the rail locomotive performs battery replacement and energy replenishment. When the unmanned rail locomotive stops, the battery replacement and energy replenishment action can be performed immediately, which greatly improves the battery replacement and energy replenishment speed of the 5G rail locomotive for mining, and enables the 5G rail locomotive for mining to be continuously dispatched and used.

[0021] The 5G mining locomotive disclosed in the present invention can also realize timely braking of the unmanned mining locomotive before battery replacement and energy replenishment through satellite positioning, so that the 5G mining locomotive can initially stop at the set battery replacement and energy replenishment position, and then use the hydraulic cylinder, push the positioning block and the positioning wheel on the locomotive head to make the locomotive head move slightly along the locomotive track after the initial stop, so that the battery pack matching groove on the head body is just aligned with the battery pack grabbing mechanism up and down, ensuring the smooth subsequent battery pack grabbing and replacement.

[0031] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0032] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. Example 1

[0033] Example 1 discloses a battery replacement and energy replenishment device for a 5G rail locomotive used in mining. Referring to FIG1 , the main body of the device includes a battery pack storage chamber 1, a battery pack grabbing mechanism 2, a dispatching frame 3, and a locomotive head 4. The dispatching frame 3 is arranged perpendicular to the locomotive track 5, and the battery pack storage chamber 1 is arranged parallel to the locomotive track 5 directly below the end of the dispatching frame 3. A belt conveyor 6 is provided at the upper end discharge port of the battery pack storage chamber 1, and a positioning baffle is provided at the outer end of the belt conveyor 6, so that the battery pack 100 in the battery pack storage chamber 1 can be sent out by the belt conveyor 6, and is positioned directly below the end of the dispatching frame 3 through the positioning effect of the positioning baffle.

[0034] Referring to Figures 3, 4 and 5, the dispatching rack 3 includes support frames 301 on both sides, and two parallel roller tracks 302 are fixedly connected to the top of the support frames 301 on both sides, and a traction device 300 is then provided between the roller tracks 302. The battery pack grasping mechanism 2 includes a movable plate 201, and two rows of rollers 202 matching the corresponding roller tracks 302 are provided on the lower surface of the movable plate 201. The traction device 300 is then connected to the movable plate 201, so that the entire battery pack grasping mechanism 2 can move along the roller tracks 302 under the action of the traction device 300. The specific traction device 300 is of conventional design, which includes a traction motor and a traction rope. A winding wheel is provided on the motor shaft of the traction motor, and the two ends of the traction rope are respectively connected to the winding wheel and the movable plate 201.

[0035] A lifting motor 203 is mounted on the upper surface of the movable plate 201. A lifting frame 204 is connected to the lower end of the lifting motor 203. A U-shaped plate base 205 is connected to the lower end of the lifting frame 204. Moving rods 206 are inserted into the left and right sides of the plate base 205. A clamping block 207 is connected to the outer end of each moving rod 206, and a moving bar 208 located on the upper surface of the plate base 205 is connected to the inner end of each moving rod 206. A lead screw motor 209 and a bearing block 210 are respectively disposed at the front and rear ends of the plate base 205. A bidirectional lead screw 211 is disposed between the motor shaft of the lead screw motor 209 and the bearing block 210, and is located on the symmetrical centerline between the two moving bars 208. Two moving blocks 212 are provided on the plate seat 205 , and the two moving blocks 212 are respectively threadedly connected to the external threads at the front and rear ends of the bidirectional screw rod 211 , and then a movable rod 213 is rotatably connected between each moving block 212 and the corresponding moving bar 208 .

[0036] During operation, the battery pack grabbing mechanism 2 in this embodiment is first moved to a set position along the roller track 302 by the traction device 300, and then the lifting motor 203 is started to move the plate seat 205 downward. After moving to the required height, the screw motor 209 is started to rotate the bidirectional screw 211. During the rotation of the bidirectional screw 211, the two moving blocks 212 move accordingly, so that the movable rod 213 is used to make the moving bars 208 on both sides approach each other, and then the clamping blocks 207 on both sides approach each other to clamp the battery pack 100.

[0037] Referring to Figures 6 and 8 , the locomotive head 4 includes a locomotive body 401 and two rows of wheels 402. A battery pack slot is defined on the upper surface of the locomotive body 401, into which the battery pack 100 is inserted to power the locomotive head 4. To prevent the battery pack 100 from being struck by falling rock from the mine, a cover 403 is rotatably connected to the battery pack slot. Furthermore, a retractable actuator 404 is provided on the locomotive body 401 to actuate the cover 402 to open and close the battery pack slot.

[0038] An electrical box 405 is also located at the rear end of the vehicle body 401. This box houses a control module, a 5G wireless communication module, a battery level detection module, and a satellite positioning module. The battery level detection module is used to monitor the remaining charge of the battery pack 100 in real time and transmit the collected data to the control module. When the remaining charge of the battery pack 100 falls below a set value, the control module sends a wireless signal to the 5G wireless communication module.

[0039] Referring to Figure 2 , the 5G rail locomotive battery replacement and energy replenishment system for mining also includes a control cabinet 7 located next to the battery pack storage compartment 1. This cabinet also houses a control module, a 5G wireless communication module, and a satellite positioning module. When the locomotive head 4 sends a wireless signal, the control cabinet 7 can promptly obtain the locomotive head 4's real-time location and the remaining charge of the battery pack 100 in the locomotive body.

[0040] Next, the control module in the control cabinet 7 issues a control command to activate the traction device 300, thereby moving the battery pack grabbing mechanism 2 to directly above the locomotive track 5. Simultaneously, the locomotive head 4 determines the distance between the two based on real-time positioning and then promptly activates the brakes to bring the locomotive head 4 to a stop directly below the battery pack grabbing mechanism 2. The entire control process is illustrated in Figure 8 .

[0041] Finally, start the battery pack grabbing mechanism 2 to first remove the battery pack 100 on the locomotive head 4 and place it, then grab the fully charged spare battery pack sent out from the battery pack storage chamber 1 and put it into the battery pack assembly slot, indicating that the rail locomotive battery replacement and energy replenishment is completed. At this time, the locomotive head 4 can be quickly put into continued use. Example 2

[0042] Example 2 discloses a 5G rail locomotive battery replacement and energy replenishment device for mining, which is an improved design based on Example 1. It mainly focuses on how to achieve that after the locomotive head 4 stops, the battery pack matching groove on the head body 401 is exactly aligned with the battery pack grabbing mechanism 2. The similarities between this Example 2 and Example 1 are not described again, and the differences are referred to Figures 1, 6 and 7.

[0043] A pair of positioning wheels 406 are installed at both ends of the upper surface of the locomotive body 401, with a distance of approximately 8 to 15 cm between the two positioning wheels 406. A vertical frame 8 is fixed to each side of the locomotive track 5 in front of the dispatching frame 3. A hydraulic cylinder 9 is fixed to the upper end of each vertical frame 8. Both hydraulic cylinders 9 are controlled by the control module within the control cabinet 7. A push positioning block 10 is connected to the movable end of the hydraulic cylinder 9 facing the locomotive track 5. The push positioning block 10 is at the same level as the positioning wheels 406 on the locomotive body 401, and the overall structure is triangular.

[0044] Through the above-mentioned structural design, in this embodiment 2, after the locomotive body 401 needs to be replaced with a battery and stopped for energy replenishment, and before the battery pack grasping mechanism 2 starts to operate, the control module inside the control cabinet 7 will issue a control instruction to make the two hydraulic cylinders 9 extend at the same time, so that the tips of the two pushing positioning blocks 10 are both extended into the gaps between the corresponding pair of positioning wheels 406. Since the pushing positioning blocks 10 are designed to have a triangular structure, the entire locomotive head 4 can be moved slightly along the locomotive track 5 through the interaction between the oblique sides of the pushing positioning blocks 10 and the positioning wheels 406, so that the battery pack assembly slot on the locomotive body 401 is just aligned with the battery pack grasping mechanism 2 up and down, and then the subsequent steps of replacing the battery pack can be carried out.

[0045] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
