[0029] Embodiments of the present disclosure are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present disclosure, and are not to be construed as limitations of the present disclosure. On the contrary, the embodiments of the present disclosure include all changes, modifications, and equivalents that fall within the spirit and connotation of the appended claims.

[0030] like Figure 1 and Figure 2 As shown, the embodiment of the present disclosure proposes a tunnel narrow-gauge transportation system, comprising: an electric locomotive 1, at least one powered flatbed vehicle 2 and a control device (not shown in the figure), wherein the electric locomotive 1 comprises: a first vehicle body 11 and at least one first running device 12, the first vehicle body 11 is arranged on the first running device 12, and the first running device 12 is used to run along the narrow track with a first output torque; the powered flatbed vehicle 2 comprises: a second vehicle body 21 and at least one second running device 22, the second vehicle body 21 is connected to the first vehicle body 11, and the second vehicle body 21 is arranged on the second running device 22, and the second running device 22 is used to run along the narrow track with a second output torque; the control device is used to adjust the first output torque and the second output torque according to a preset driving speed and a preset distribution ratio.

[0031] It can be understood that, since the first vehicle body 11 is arranged on the first running device 12, and the first running device 12 is used to run along the narrow track with the first output torque, the electric locomotive 1 can use the first running device 12 to achieve running, and since the second vehicle body 21 is arranged on the second running device 22, the second running device 22 is used to run along the narrow track with the second output torque, the power flatbed vehicle 2 can use the second running device 22 to achieve running, and at the same time, since the control device adjusts the first output torque and the second output torque according to the preset driving speed and the preset distribution ratio, power distribution can be achieved between the electric locomotive 1 and the power flatbed vehicle 2. Therefore, the additional torque provided by the power flatbed vehicle 2 can avoid the modification of the electric locomotive 1 while making the transportation system have greater driving power, thereby meeting the driving and transportation needs of the transportation system on the narrow track of the tunnel.

[0032] It should be noted that the electric locomotive 1 is the core component of the whole vehicle, providing the power supply and the overall control system for the whole vehicle, and also carrying out appropriate counterweight. Since the power flatbed 2 provides additional torque, the power of the first running device 12 in the electric locomotive 1 can be designed to be smaller, that is, while achieving greater power for the transportation system, the size of the electric locomotive 1 can also be reduced, so as to better adapt to the narrow-gauge transportation scenario in the tunnel. Among them, the specific type of the electric locomotive 1 can be set according to actual needs, and there is no restriction on this. For example, the electric locomotive 1 adopts a size of 6620mm×1200mm×1800mm, with two first running devices 12, and the rated power of the motor in each first running device 12 is 45KW, which is smaller than the body size and rated power of the traditional electric locomotive 1.

[0033] The first vehicle body 11 is the main structural part of the electric locomotive 1. The specific type of the first vehicle body 11 can be set according to actual needs and is not limited to this. For example, the first vehicle body 11 may include: a first frame and a driver's cab, an air compressor, a battery, etc. arranged on the first frame.

[0034] The first running device 12 is the running part of the electric locomotive 1. The specific type of the first running device 12 can be set according to actual needs and is not limited to this. By way of example, the first running device 12 may include: a wheel group arranged at the bottom of the first frame, and a braking system, a motor, etc. arranged on the first frame and transmission-connected to the wheel group.

[0035] The power flatbed truck 2 is a self-propelled flatbed truck, which is used to cooperate with the electric locomotive 1 to provide additional torque for the transportation system, thereby improving the transportation capacity of the transportation system. The specific type of the power flatbed truck 2 can be set according to actual needs and is not limited to this. For example, the power flatbed truck 2 adopts an outer dimension of 6052mm×1200mm×1700mm and has two second walking devices 22. The rated power of the motor in each second walking device 22 is 37KW, and the size and power are slightly smaller than the electric locomotive 1.

[0036] The second vehicle body 21 is the main structural part of the power flatbed vehicle 2. The specific type of the second vehicle body 21 can be set according to actual needs and is not limited to this. For example, the second vehicle body 21 can be composed of end face sealing plates, side plates, baffles, upper cover plates, lower cover plates, cross plates, reducer fixing seats, I-beams, etc. The structure between the upper and lower cover plates constitutes an intermediate beam, which mainly plays the role of bearing and transmitting the force. The left and right ends are used to fix the drive motor 223. Therefore, various parts make the second vehicle body 21 form the structure of a second frame.

[0037] The second traveling device 22 is the traveling part of the power flatbed vehicle 2. The specific type of the second traveling device 22 can be set according to actual needs and is not limited thereto.

[0038] The control device is used for power distribution between the electric locomotive 1 and the powered flatbed truck 2. The specific type of the control device can be set according to actual needs and is not limited to this. For example, the control device can be a control system in the electric locomotive 1. The output end of the control device is respectively connected to the motor input end of the first walking device 12 and the motor input end of the second walking device 22. The control device adjusts the first output torque of the motor in the first walking device 12 and the second output torque of the motor in the second walking device 22 according to a preset driving speed and a preset distribution ratio.

[0039] Among them, under the control of the control device, the combined braking of the electric locomotive 1 and the power flatbed vehicle 2 can also be achieved, and the braking effect is significantly improved.

[0040] like Figure 3 As shown, in some embodiments, the second walking device 22 includes: a bearing box 221, a wheelset 222 and a driving mechanism, wherein the second vehicle body 21 is arranged on the bearing box 221, and the wheelset 222 and the bearing box 221 are rotationally connected and rollingly arranged on the narrow track, and the driving mechanism is transmission-connected to the wheelset 222, and the driving mechanism is used to drive the wheelset 222 to rotate with the second output torque.

[0041] It can be understood that since the second vehicle body 21 is arranged on the bearing box 221, and the wheelset 222 and the bearing box 221 are rotatably connected and rollingly arranged on the narrow track, the driving mechanism and the wheelset 222 are transmission-connected, so that the driving mechanism can drive the wheelset 222 to rotate with the second output torque under the control of the control device, thereby realizing the walking of the second vehicle body 21 on the narrow track, thereby enabling the power flatbed truck 2 to provide additional torque for the transportation system, thereby avoiding the modification of the electric locomotive 1 and enabling the transportation system to have greater driving power.

[0042] It should be noted that the bearing box 221 is used to support the second vehicle body 21. The specific type of the bearing box 221 can be set according to actual needs and is not limited to this. For example, the bearing box 221 has a built-in bearing. The bearing box 221 is provided with two symmetrical bearing boxes. The two bearing boxes 221 are used to rotate the connecting wheel pair 222. At the same time, the second vehicle body 21 can be arranged on the bearing box 221.

[0043] The wheelset 222 is used to self-rotate under the drive of the driving mechanism, so as to provide additional walking power, braking force, etc. for the transport vehicle group. The specific type of the wheelset 222 can be set according to actual needs and is not limited to this. For example, the wheelset 222 includes: an axle and two wheels, and the two wheels are respectively arranged at the two ends of the axle, and the end portions of the axle are respectively rotatably arranged in two opposite bearing boxes 221 using spherical roller bearings.

[0044] The driving mechanism is used to drive the wheel pair 222 to rotate so as to realize self-driven movement of the power flatbed vehicle 2. For example, if the driving mechanism drives the wheel pair 222 to rotate in the forward direction, the power flatbed vehicle 2 can provide additional walking power; if the driving mechanism drives the wheel pair 222 to rotate in the reverse direction, the power flatbed vehicle 2 can provide additional braking power. The specific type of the driving mechanism can be set according to actual needs and is not limited to this.

[0045] like Figure 3 As shown, in some embodiments, the driving mechanism includes: a driving motor 223 and a reducer 224, the driving motor 223 is arranged vertically, and the power output end of the driving motor 223 is located at the bottom, the power input end of the reducer 224 is connected to the power output end of the driving motor 223, and the power output end of the reducer 224 is connected to the wheelset 222 for transmission.

[0046] It can be understood that since the power input end of the reducer 224 is connected to the power output end of the drive motor 223, and the power output end of the reducer 224 is transmission-connected to the wheelset 222, the reducer 224 can convert the power output by the drive motor 223 to drive the wheelset 222 to rotate, thereby realizing self-driving movement of the power flatbed vehicle 2.

[0047] Furthermore, since the drive motor 223 is arranged vertically and the power output end of the drive motor 223 is located at the bottom, the main body of the drive motor 223 can be located at a higher position, thereby facilitating the safe rotation, inspection and maintenance of the drive motor 223 and improving the overall wading performance of the bean gravel vehicle, thereby avoiding the risk of water entering the drive motor 223 when the power flatbed vehicle 2 is in a tunnel with water accumulation on the V-shaped slope.

[0048] At the same time, compared with the internal combustion engine, the method of using the driving motor 223 to drive the power flatbed vehicle 2 to move can also effectively reduce the noise in the tunnel and reduce the air pollution in the tunnel.

[0049] It should be noted that the drive motor 223 is used to provide driving force for the self-propelled walking of the power flatbed vehicle 2. The specific type of the drive motor 223 can be set according to actual needs and is not limited to this. Among them, due to the vertical arrangement of the drive motor 223, an avoidance opening is set at the corresponding position of the second vehicle body 21, and the drive motor 223 runs through the avoidance opening.

[0050] The reducer 224 is used for power conversion between the driving motor 223 and the wheelset 222. The specific type of the reducer 224 can be set according to actual needs and is not limited to this.

[0051] Among them, the motor of the first walking device 12 is used as the main motor, and the motor of the second walking device 22 is used as the slave motor, thereby forming a "one master and multiple slaves" walking drive mode. Specifically, due to the hard connection between the motors, the speed of each motor remains consistent, and the actual operating speed tracks the main motor speed command. The main motor speed control ensures that the speed of the electric locomotive 1 follows the set acceleration and deceleration curve during the acceleration and deceleration process. The control device strictly controls the speed according to the main motor speed command to timely adjust the output torque of the main motor and adjust the distribution of the output torque of each slave motor.

[0052] like Figure 1 As shown, in some embodiments, the driving mechanism further includes: a protective cover 225 , the protective cover 225 is disposed on the second vehicle body 21 , and the driving motor 223 is located inside the protective cover 225 .

[0053] It is understandable that, since the protective cover 225 is disposed on the second vehicle body 21 and the drive motor 223 is located in the protective cover 225 , the protective cover 225 can effectively protect the drive motor 223 , thereby ensuring the stable operation of the drive motor 223 .

[0054] It should be noted that the protective cover 225 is used to protect the drive motor 223. The protective cover 225 can reduce the environmental impact on the drive motor 223 and prevent the drive motor 223 from being directly impacted. The specific type of the protective cover 225 can be set according to actual needs and is not limited to this. For example, the protective cover 225 can be a cover body structure, and the protective cover 225 has an inspection door.

[0055] The space inside the protective cover 225 can be further fully utilized. For example, the resistor cabinet, the junction box and the electrical cabinet are respectively arranged inside the protective cover 225.

[0056] like Figure 3 As shown, in some embodiments, the frame is vertically slidably arranged on the bearing box 221; the second walking device 22 also includes: at least one buffer assembly, the buffer assembly includes: a first spring 226 and a second spring (not shown in the figure), the first spring 226 and the second spring are respectively arranged between the frame and the bearing box 221, and the first spring 226 is located on the inner side of the second spring.

[0057] It is understandable that, since the first spring 226 and the second spring are respectively arranged between the vehicle frame and the bearing box 221, and the first spring 226 is located on the inner side of the second spring, the first spring 226 and the second spring can be used to buffer the impact force between the vehicle frame and the bearing box 221. Therefore, through the cooperation of the first spring 226 and the second spring, the vibration effect on the second vehicle body 21 can be reduced, ensuring the stable and safe walking of the power flatbed vehicle 2.

[0058] It should be noted that the first spring 226 and the second spring are both used for buffering the impact force between the frame and the bearing box 221. The specific types of the first spring 226 and the second spring can be set according to actual needs and are not limited to this. For example, the ear plate extending from the frame is slidably mounted on the guide column on the bearing box 221. The first spring 226 and the second spring are both coil springs and are mounted on the guide column.

[0059] like Figure 1 As shown, in some embodiments, the powered flatbed vehicle 2 further includes: a counterweight box 23 , which is disposed on the second vehicle body 21 , and is used to increase the weight of the powered flatbed vehicle 2 .

[0060] It can be understood that since the counterweight box 23 is arranged on the second vehicle body 21, the powered flatbed vehicle 2 can use the counterweight box 23 to increase its own viscosity, thereby significantly increasing the friction between the wheels and the rails, avoiding the occurrence of slipping, and thus effectively improving the stability and safety of the transportation system, reducing the wear between the wheels and the rails, and being able to ensure that the motor power does not exceed the maximum value within a certain slope range.

[0061] It should be noted that, in the relevant embodiments, increasing the friction between the rails also requires adding counterweights to the electric locomotive 1. However, for narrow-gauge rails, the structure of the electric locomotive 1 is compact and difficult to modify, which can easily lead to uneven weight distribution of the electric locomotive 1, and the pressure between the rails is difficult to control, which can damage the rails and wheels, further causing braking problems. In this embodiment, by increasing the sticky weight of the power flatbed vehicle 2, the counterweight design of the electric locomotive 1 can be reduced, thereby ensuring that the electric locomotive 1 is adaptable to narrow-gauge rail scenarios.

[0062] The counterweight box 23 is used to increase the weight of the power flatbed vehicle 2. The specific type of the counterweight box 23 can be set according to actual needs, and there is no limitation on this. For example, the counterweight box 23 is a box structure, and a plurality of detachable counterweight blocks are arranged inside. Among them, after the power flatbed vehicle 2 adopts the counterweight box 23, the overall deadweight is 15t, and the weight of the electric locomotive 1 can be set to 20t, which is lower than the traditional electric locomotive 1.

[0063] like Figure 1 As shown, in some embodiments, a slot 211 is provided on the second vehicle body 21, and the bottom of the counterweight box 23 is clamped in the slot 211, and the counterweight box 23 is provided with at least one lifting ring 24, and the lifting ring 24 is used to connect the hook of the lifting equipment.

[0064] It can be understood that since a slot 211 is provided on the second vehicle body 21 and the bottom of the counterweight box 23 is clamped in the slot 211, the counterweight box 23 can be arranged in a detachable manner by utilizing its clamping in the slot 211, thereby ensuring that the counterweight box 23 can be stably set on the second vehicle body 21 while also facilitating the counterweight adjustment of the powered flatbed truck 2.

[0065] Since the counterweight box 23 is provided with at least one lifting ring 24, and the lifting ring 24 is used to connect the lifting hook of the lifting equipment, the counterweight box 23 can be lifted by the lifting equipment by using the cooperation of the lifting ring 24 and the lifting hook, thereby making the disassembly and assembly of the counterweight box 23 more convenient.

[0066] It should be noted that the slot 211 is used to clamp the bottom of the counterweight box 23. The specific type of the slot 211 can be set according to actual needs and is not limited to this. For example, four relatively set L-shaped baffles are provided on the second vehicle body 21, and the four L-shaped baffles form a rectangular slot 211 to clamp the counterweight box 23 with a rectangular structure.

[0067] The lifting ring 24 is used to cooperate with the hook of the lifting equipment to realize the lifting of the counterweight box 23. The specific type of the lifting ring 24 can be set according to actual needs and is not limited to this. For example, the lifting ring 24 is arranged on the side of the counterweight box 23 with a hinge. Multiple lifting rings 24 can be arranged, and multiple lifting rings 24 are evenly distributed along the circumference of the counterweight box 23.

[0068] like Figure 1 As shown, in some embodiments, at least one second walking device 22 includes: two second walking devices 22, and the two second walking devices 22 are respectively located at two ends of the second vehicle body 21; and the counterweight box 23 is located in the middle of the second vehicle body 21.

[0069] It can be understood that since the two second walking devices 22 are respectively located at the two ends of the second vehicle body 21, and the counterweight box 23 is located in the middle of the second vehicle body 21, the weight distribution of the second vehicle body 21 is more uniform, thereby making the operation of the powered flatbed vehicle 2 more stable and safe.

[0070] like Figure 4 As shown, in some embodiments, the transportation system further includes: a vehicle blocking device 3, the vehicle blocking device 3 includes: a vehicle blocking member 31, a locking member 32 and a driving member 33, the vehicle blocking member 31 is slidably arranged on the first vehicle body 11, the locking member 32 is movably arranged on the first vehicle body 11, and the locking member 32 and the vehicle blocking member 31 are engaged, the signal input end of the driving member 33 is connected to the signal output end of the control device, and the power output end of the driving member 33 is transmission-connected to the locking member 32. Among them, when the control device determines that the speed of the electric locomotive 1 is out of control, the driving member 33 is used to drive the locking member 32 to disengage from the vehicle blocking member 31, so that the vehicle blocking member 31 falls between adjacent sleepers of the narrow track.

[0071] It can be understood that since the signal input end of the driving member 33 is connected to the signal output end of the control device, and the power output end of the driving member 33 is transmission-connected to the locking member 32, the driving member 33 can drive the locking member 32 to operate under the control of the control device, thereby realizing the disengagement of the locking member 32 and the vehicle blocking member 31, and since the vehicle blocking member 31 is slidingly arranged on the first vehicle body 11, after the locking member 32 is disengaged, the vehicle blocking member 31 can be released and achieve free fall.

[0072] Therefore, when the control device determines that the speed of the electric locomotive 1 is out of control, the driving member 33 drives the locking member 32 to disengage from the vehicle blocking member 31, so that the vehicle blocking member 31 falls between adjacent sleepers in the tunnel, thereby utilizing the cooperation between the vehicle blocking member 31 and the sleepers to achieve the parking of the electric locomotive 1, thereby ensuring the safe operation of the transportation system. At the same time, the vehicle blocking method using the vehicle blocking member 31 falling between adjacent sleepers is not only not restricted by the vehicle's driving direction, but also avoids the problems of the hook slipping, bouncing and being unable to hook, and has higher reliability and stronger safety protection capabilities as a whole.

[0073] It should be noted that in the relevant embodiments, the electric locomotive 1 relies on the hook to hook the sleeper to achieve the anti-walking function, but due to the hook structure of the hook, the whole can only block the vehicle in one direction. Specifically, in order to facilitate the unloading of materials at the trolley in the shield / TBM (full-section rock tunneling machine) tunnel, the vehicle marshaling is generally reversed into the tunnel, and the hook is usually set in front of the front of the electric locomotive 1. When the vehicle exits the tunnel, the hook cannot hook the sleeper to achieve anti-walking. The intelligent vehicle blocking device 3 of this embodiment uses the vehicle blocking member 31 to fall between the adjacent sleepers of the tunnel to achieve the vehicle blocking function, whether the vehicle is moving forward or backward, it can achieve the effect of blocking the vehicle.

[0074] In addition, the hook structure of the hook may slip after hooking the sleeper, or the hook may bounce and fail to hook the sleeper. The vehicle blocking device 3 of this embodiment eliminates the hook structure and uses the vehicle blocking member 31 to fall between adjacent sleepers in the tunnel to achieve vehicle blocking, thereby avoiding the problems of the hook slipping, bouncing and failing to hook, etc.

[0075] The vehicle stopper 31 is used to fall between adjacent sleepers in the tunnel to achieve the parking and anti-rolling function of the electric locomotive 1. Specifically, when the vehicle stopper 31 falls between adjacent sleepers in the tunnel, as the electric locomotive 1 continues to move, the vehicle stopper 31 moves to the sleepers and gets stuck, thereby using the sleepers to block the continued movement of the electric locomotive 1, thereby achieving the anti-rolling function. The specific type of the vehicle stopper 31 can be set according to actual needs and is not limited to this. For example, the vehicle stopper 31 can be made of a material with high structural strength such as metal. The vehicle stopper 31 can be a columnar structure close to a rectangular parallelepiped. The vehicle stopper 31 is slidably set on the first vehicle body 11 along the vertical direction using a guide sleeve 34.
