Those skilled in the art will understand the specific meanings of these terms in this utility model based on specific circumstances.

[0048] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0049] This embodiment relates to an electric rack rail car, the overall structure of which is as follows: Figure 1 As shown, it includes a vehicle frame, a battery module 1, a vehicle control device 2, a drive mechanism 3, a bogie 4 and a driver's cab 5.

[0050] The vehicle frame includes a first frame 6, a second frame 7, and a third frame 8 that are hinged to each other. The battery module 1 is mounted on the second frame 7 to drive the various drive mechanisms 3 and other electrical devices.

[0051] The vehicle control device 2 is separately provided on the second frame 7 and the third frame 8 , and the drive mechanism 3 is separately provided on the second frame 7 and the third frame 8 , and the drive mechanism 3 on the second frame 7 is configured as two arranged at intervals along the length direction of the second frame 7 .

[0052] In addition, the driver's cab 5 is mounted on the first frame 6 and the third frame 8, and faces the forward and reverse directions of this embodiment, respectively, so that the electric rack rail vehicle of this embodiment can move forward or reverse on the rack rail. The bogie 4 is mounted on the first frame 6 and the third frame 8 to ensure that each frame can move normally along the rack rail.

[0053] As described above, by coordinating the storage module and multiple drive mechanisms 3, electric energy is used to drive multiple drive mechanisms 3 to drive the rack rail vehicle to travel. Compared with the driving method of the internal combustion engine used in the prior art, it can reduce the pollution to the underground working environment. At the same time, the rack rail vehicle driven by electricity in this embodiment has a large driving force and good climbing ability, which can meet the needs of heavy-load transportation.

[0054] Based on the above overall introduction, specifically, since the battery module 1 is heavy, in order to improve the fixing stability of the battery module 1 on the vehicle frame, Figure 2 、 Figure 3As shown, the battery module 1 of this embodiment includes a battery tray 101 and a plurality of battery modules 102 stacked on the battery tray 101. Positioning holes 103 are provided at the four corners of the battery tray 101, and a plurality of positioning pins 701 corresponding to the positioning holes 103 are provided on the second frame 7. A shock absorber 702 for supporting the battery tray 101 is also provided on the second frame 7. By providing the positioning pins 701 and the positioning holes 103, after the battery module 102 is installed on the second frame 7 through the battery tray 101, the battery module 102 is prevented from sliding with the second frame 7 due to vibration or tilting of the frame during driving, thereby preventing the battery module 102 from detaching and improving the fixing stability of the battery module 102. In addition, the setting of the shock absorber 702 can reduce the transmission of vibration to the battery module 102 to a certain extent when the second frame 7 vibrates due to driving, reduce the probability of damage to the battery module 102 due to vibration, and ensure the normal operation of the battery module 102.

[0055] In a specific implementation, four shock absorbers 702 are provided in this embodiment and are located adjacent to each positioning pin 701. The shock absorbers 702 in this embodiment can be conventional shock absorbers 702 known to those skilled in the art, such as hydraulic shock absorbers 702, shock absorbing springs, etc., as long as they can provide a shock-absorbing effect and reduce the transmission of vibration to the battery module 102.

[0056] Since there are certain curved sections in the rack rails in the mine, in order to ensure the smooth running of the electric rack rail car along the rack rails, Figure 3 、 Figure 4 、 Figure 6 As shown, an annular slideway 301 is formed on both the second and third frames 7, 8 of this embodiment. The drive mechanism 3 also includes an annular frame 302, a drive wheel 303 located in the center of the frame 302, and a first wheel set 304 located at the bottom of the frame 302. The frame 302 slides within the annular slideway 301, and the drive wheel 303 is provided with a meshing portion around its circumference for engaging with the teeth of the rack. In a specific embodiment, the drive wheel 303 is driven by a motor and is equipped with a caliper for braking.

[0057] In addition, the first wheel assembly 304 is disposed on either side of the drive wheel 303, and the first wheel assembly 304 is configured to roll on the rack track. The coordinated arrangement of the frame 302 and the annular slideway 301 allows the frame 302 to drive the drive wheel 303 and the first wheel assembly 304 to rotate about the axis of the annular slideway 301. When the electric rack rail vehicle of this embodiment reaches a curved section of the rack rail, the drive wheel 303 and the first wheel assembly 304 rotate with the curvature of the rack rail, allowing the vehicle frame equipped with the drive mechanism 3 to smoothly turn, thereby ensuring smooth operation of the electric rack rail vehicle.

[0058] Specifically, in order to improve the smoothness of the rotation of the rack 302, as Figure 5 As shown, in this embodiment, two first sliders 3021 are rotatably connected to the front and rear ends of the frame 302, and two second sliders 3022 are rotatably connected to the left and right sides of the frame 302. The first slider 3021 and the second slider 3022 are slidably disposed in the annular slide 301 and slide along the annular slide 301. The provision of the first slider 3021 and the second slider 3022 can reduce friction between the frame 302 and the annular slide 301 while ensuring a secure connection between the frame 302 and the annular slide 301, thereby improving the smoothness of the rotation of the frame 302.

[0059] It is understandable that in the complex environment of the mine, in addition to the straight sections and the above-mentioned curved sections, the rack rail also has uphill sections and downhill sections, which will cause some rack rail sections to have a certain inclination angle in the left and right directions of the rack rail vehicle.

[0060] In order to improve the passability of the electric rack rail vehicle in this embodiment, in this embodiment, Figure 6 As shown, in the height direction, a certain distance is formed between the upper and lower ends of the second slider 3022 and the upper and lower ends of the inner wall of the annular slide 301. This distance allows the second sliders 3022 on both sides of the frame 302 to have a certain height-direction movable space within the annular slide 301. This allows the frame 302, through the rotational connection of the first slider 3021, to swing left and right relative to the vehicle frame, i.e., the second frame 7 and the third frame 8, so that the driving wheel 303 and the first wheel set 304 in the driving mechanism 3 can tilt with the tilt of the rack.

[0061] The spacing between the upper and lower ends of the second slider 3022 allows the drive mechanism 3 to swing left and right to accommodate the tilt of the rack rail, thereby preventing the electric rack rail vehicle from tilting excessively and overturning, thereby improving the passability of the electric rack rail vehicle. In addition, the upper and lower ends of the second slider 3022 of this embodiment can also be made of elastic material. In this case, when the drive mechanism 3 swings left and right to the extreme position, the upper and lower ends of the second slider 3022 can form a buffer to prevent damage to the frame 302 or the annular slide 301 due to collision.

[0062] In this embodiment, the first wheel group 304 includes a first wheel group bracket 3041, a first running wheel 3042 and a first guide wheel 3043 provided on the first wheel group bracket 3041. The first running wheel 3042 is arranged vertically and abuts the top of the track, and the first guide wheel 3043 is arranged horizontally and abuts the outer side of the track to play a guiding role. The first running wheel 3042 and the first guide wheel 3043 are both configured to be arranged in a plurality of intervals along the length direction of the first wheel group bracket 3041. Through the arrangement of the first guide wheel 3043 and the first running wheel 3042, in the curved section of the rack rail, the first guide wheel 3043 of the first wheel group 304 can play a guiding role and drive the drive mechanism 3 to turn along the curved section of the rack rail, and the first running wheel ensures the contact area between the electric rack rail vehicle and the rack rail, thereby ensuring that the electric rack rail vehicle can stably travel on the rack rail and detect the risk of derailment. During specific implementation, two of the first running wheels 3042 and two of the first guide wheels 3043 are respectively configured to ensure the running effect and guiding effect of the first wheel set 304 on the track.

[0063] In addition, since the rack rail has uphill and downhill sections, the top of the first wheel group bracket 3041 of this embodiment is hinged on the frame 302, so that the first wheel group 304 can pitch in the forward direction of the electric rack rail vehicle as the rack rail rises and falls, so as to ensure that the first wheel group 304 and the driving wheel 303 in the driving mechanism 3 are always in contact with the rack rail, thereby improving the driving stability of the electric rack rail vehicle of this embodiment.

[0064] like Figure 7 、 Figure 8As shown, the bogie 4 of this embodiment includes a bogie seat 401, a connecting beam 402, and a second wheel set 403. The bogie seat 401 is rotatable in the horizontal direction and is arranged at the bottom of the first frame 6 or the third frame 8. The middle part of the connecting beam 402 is hinged on the bogie seat 401, and the two second wheel sets 403 are hinged on the two opposite ends of the connecting beam 402. A shock absorbing mechanism 404 is connected between the bogie seat 401 and the connecting beam 402. Through the arrangement of the bogie seat 401 and the connecting beam 402, the bogie 4 can turn with the bending of the rack rail and tilt with the tilt of the rack rail, so as to ensure that the head and tail ends of the electric rack rail vehicle, that is, the first frame 6 and the third frame 8, can turn smoothly, thereby improving the passability of the electric rack rail vehicle. In addition, the second wheel assembly 403 of this embodiment includes a second wheel assembly bracket 4031 connected to the connecting beam 402, a second running wheel 4032, and a second guide wheel 4033. The second running wheel 4032 abuts the top of the rack rail, and the second guide wheel 4033 is arranged transversely and abuts the outer side of the rail. The second running wheel 4032 and the second guide wheel 4033 are arranged in a plurality of spaces along the length of the second wheel assembly bracket 4031. This provides a good guiding effect and driving effect, and can further ensure that the bogie 4 follows the rack rail when turning and tilting.

[0065] In this embodiment, the vehicle control device 2 includes an electronic control system electrically connected to the battery module 1 and a hydraulic system for braking the drive mechanism 3. The electronic control system is used to control the starting and stopping of the drive wheels 303 and the operation of other electrical devices on the electric rack rail vehicle. The hydraulic system is used to actuate the calipers on the drive wheels 303, enabling them to clamp and brake the drive wheels 303. Therefore, in this embodiment, the vehicle control device 2 is mounted on both the second frame 7 and the third frame 8, which are equipped with the drive mechanism 3. Furthermore, in a specific implementation, the vehicle control device 2 of this embodiment also includes a cooling system for cooling the motor of the drive wheels 303 and the electrical components of the electronic control system.

[0066] Finally, if Figure 9 As shown, in this embodiment, a radar 501, a lighting 502, and a camera 503 are provided on the top side of the cab 5 facing the direction of travel. A display screen connected to the radar 501 and the camera 503 is provided in the cab 5, and the driver can view the road conditions captured by the camera 503 on the display screen. The radar 501 is used to detect obstacles in the direction of travel of the cab 5. When the radar 501 detects an obstacle in front of the vehicle, it can send an alarm message to the display screen to alert the driver. At the same time, the radar 501 is also connected to the vehicle control device 2. When the radar 501 detects an obstacle in front of the vehicle, the vehicle control device 2 brakes the drive mechanism 3, thereby improving the safety of the battery rack rail vehicle.

[0067] In summary, the battery rack rail car of this embodiment, through the coordinated arrangement of the power storage module and multiple drive mechanisms 3, uses electric energy to drive the multiple drive mechanisms 3 to drive the rack rail car to move. Compared with the driving method of the internal combustion engine used in the prior art, it can reduce the pollution to the underground working environment. At the same time, the rack rail car driven by electricity in this embodiment has a large driving force, good climbing ability, can meet the needs of heavy-load transportation, and has good usability.
