Obviously, the described embodiments are only part of the embodiments of this application. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative work should fall within the scope of protection of this application.

[0031] Example 1:

[0032] like Figures 1-3 As shown, this embodiment is an electric rail vehicle comprising a frame 39, an air tank 5, a moving mechanism, a brake mechanism, and a track 1. A first cab 4 is mounted on one end of the frame 39, and a second cab 33 is mounted on the other end. The first cab 4 is equipped with a controller 9, a first control button 2, a first foot switch 10, and a first foot accelerator 17. The second cab 33 is equipped with a second foot switch 35, a second foot accelerator 34, and a second control button 37. The air tank 5 is mounted on the top of the first cab 4 and serves as a source of pressurized gas. At least two moving mechanisms are mounted on the bottom of the frame 39 to support the movement of the frame. A drive mechanism is mounted on the bottom of the frame 39 and is in transmission connection with one of the moving mechanisms. A brake mechanism is mounted on one of the at least two moving mechanisms for braking. The track is embedded in the ground, and the moving mechanism is rotatably mounted on the track 1. The first control button 2, the second control button 37, the first foot accelerator 17, the second foot accelerator 34, and the drive mechanism are all electrically connected to the controller 9. The air storage tank 5 is connected to the air inlet ends of the first foot switch 10 and the second foot switch 35 , and the air outlet ends of the first foot switch 10 and the second foot switch 35 are connected to the brake mechanism.

[0033] A driver's cab is mounted on each end of the vehicle frame 39, facilitating the control of the electric rail vehicle along the track and improving safety. It is understood that the first driver's cab can be used for control when the electric rail vehicle is moving forward. When the electric rail vehicle is reversing, the second driver's cab can be used for control. This facilitates the driver's ability to observe and assess potential hazards affecting safe operation along the route of the electric rail vehicle. It is understood that the driver can switch between the first and second driver's cabs as needed.

[0034] The driving mechanism serves as a power source, driving the moving mechanism connected thereto to move along the track, and the moving mechanism drives the vehicle frame to move.

[0038] The gas tank 5 stores compressed air, which is used to provide compressed air to the first foot switch 10 and the second foot switch 35.

[0039] It can be understood that the brake mechanism is a brake that uses gas with pressure as driving force.

[0040] The track has a structure shape of a H-shaped surface contact rail.

[0041] It should be noted that when the foot accelerator is pressed downward, the electric rail vehicle accelerates, and when the foot accelerator is lifted upward, the electric rail vehicle slows down.

[0042] In order to remind pedestrians, warning lights are installed, such as Figure 1 As shown in the figure, the first warning light 8 is installed on the top of the first cab 4. The second warning light 38 is installed on the top of the second cab 33. When the electric rail vehicle runs, the first warning light and the second warning light flash or flash and emit a warning sound.

[0043] Working mode:

That is, the power control button in the first control button 2 is pressed, the controller 9 is powered on, and the driving mechanism is powered on standby. Then the advance control button is pressed, and then the first foot accelerator 17 is pressed downward with the foot. The driving mechanism starts and drives the moving mechanism connected therewith, and under the interaction of the moving mechanism and the remaining moving mechanism, the vehicle frame 39 moves forward, that is, the electric rail vehicle moves forward. When the electric rail vehicle reaches the desired position, the foot is lifted from the first foot accelerator, and the first foot switch 10 is pressed. The first foot switch 10 controls the brake mechanism to work, and the brake mechanism brakes, so that the electric rail vehicle accelerates to stop. Then, the power control button is pressed again, and the controller 9 and the driving mechanism are powered off.

[0045] When the electric rail vehicle needs to move reversely, the driver enters the second driver's cab 33, presses the power control button in the second control button 37, the controller 9 is powered on, and the driving mechanism is powered on standby. Then press the forward button in the second control button 37, step on the second foot accelerator 34, the driving mechanism works, and reversely drives the moving mechanism connected with it, and under the interaction of the remaining moving mechanism, the vehicle frame 39 moves backward, that is, the electric rail vehicle moves backward. When moving to the desired position, step off the second foot accelerator, and step on the second foot switch 35, the second foot switch 35 controls the brake mechanism to work, the brake mechanism brakes, and the electric rail vehicle accelerates to stop. Then, press the power control button again, and the controller 9 and the driving mechanism are powered off.

[0046] In some optional embodiments, a mounting structure of the driving mechanism is given. As shown in Figure 1 , 2 A support column 19, a support plate 20, a spring 42, a first support 43, a threaded rod 44 and a nut 45 are added.

[0047] As shown in Figure 2 , a mounting structure of the spring is given, and a rear stop ring 41 is added. The spring 42 is sleeved on the support column 19 and connected with the stop ring 41.

[0048] The first support 43 is installed at the bottom of the vehicle frame, and the support plate 20 is suspended at the bottom of the vehicle frame through the support column 19.

[0049] The spring 42 can play a damping effect on the driving mechanism installed on the support plate.

[0050] The number of nuts 45 installed on the threaded rod 44 can be 2, 3 or 4, etc. The appropriate number of nuts can be selected according to the needs.

[0051] The nut is connected with the threaded rod in screw thread, the threaded rod is connected with the support column, and the nut can block the threaded rod from being separated from the first support downward, so that the threaded rod pulls the support column, so that the support column is suspended on the first support, and then the support plate is suspended on the first support through the support column, realizing that the support column and the support plate are installed at the bottom of the vehicle frame.

[0052] In some optional embodiments, a baffle 40 is added. As shown in Figure 2 , the baffle 40 is installed on the support plate 20 close to the driving mechanism.

[0053] The baffle 40 can play a supporting and blocking effect on the driving mechanism. It is beneficial to the installation of the driving mechanism on the support plate.

[0054] In some embodiments, a control structure of the pressurized gas is provided, which increases the installation of the gas supply main pipe 6, the first gas supply pipe 13, the first three-way valve 14, the second gas supply pipe 15, the gas valve 16, the first gas outlet pipe 11, the second gas outlet pipe 12, the third gas supply pipe 22, the second three-way valve 23, the third gas outlet pipe 24, the fourth gas outlet pipe 25, the third three-way valve 26, the fourth three-way valve 27, the fifth gas outlet pipe 28, the gas inlet pipe 29 and the sixth gas outlet pipe 30.

[0055] As shown in the drawings, the gas tank 5 is provided with a gas pipe joint 7. Figure 1

[0056] As shown in the drawings, Figure 1 , 3 The one end of the gas supply main pipe 6 is connected with the gas pipe joint 7 of the gas tank 5, and the other end is connected with one port of the first three-way valve 14. One of the remaining two ports of the first three-way valve 14 is connected with one end of the first gas supply pipe 13, and the other is connected with one end of the second gas supply pipe 15. The other end of the first gas supply pipe 13 is connected with the gas inlet end of the first foot switch 10, and the other end of the second gas supply pipe 15 is connected with one end of the gas valve 16. One of the two gas outlet ends of the first foot switch 10 is connected with one end of the first gas outlet pipe 11, and the other is connected with one end of the second gas outlet pipe 12. The other end of the first gas outlet pipe 11 is connected with the first port of the second three-way valve 23, and the second gas outlet pipe 12 is connected with the second port of the second three-way valve 23. The third port of the second three-way valve 23 is connected with one end of the third gas outlet pipe 24, and the other end of the third gas outlet pipe 24 is connected with the first port of the third three-way valve 26. The second port of the third three-way valve 26 is connected with one end of the fourth gas outlet pipe 25, and the third port of the third three-way valve 26 is connected with one end of the gas inlet pipe 29. The other end of the gas inlet pipe 29 is connected with the brake mechanism. The other end of the fourth gas outlet pipe 25 is connected with the first port of the fourth three-way valve 27, and the second port of the fourth three-way valve 27 is connected with one end of the fifth gas outlet pipe 28. The third port is connected with one end of the sixth gas outlet pipe 30. The other end of the fifth gas outlet pipe 28 is connected with one gas outlet port of the second foot switch 35, and the other end of the sixth gas outlet pipe 30 is connected with the other gas outlet port of the second foot switch 35. One end of the third gas supply pipe 22 is connected with the other end of the gas valve 16, and the other end is connected with the gas inlet port of the second foot switch 35.

[0057] The first foot switch 10 and the second foot switch 35 are both foot switches provided with two gas outlet ports and one gas inlet port.

[0058] It should be noted that stepping on the first foot switch 10 and the second foot switch 35 can provide pressurized gas to the brake mechanism. The brake mechanism can achieve brake braking when it gets pressurized gas.

[0059] ​​When the first foot switch 10 is stepped on, the gas flow is as follows: the pressurized gas in the gas tank 5 is transported to the first three-way valve 14 through the gas main 6, enters the first gas pipe 13 through the first three-way valve 14, and then enters the first foot switch 10 through the first gas pipe 13. Then, the gas flows outward from the two gas outlets on the first foot switch 10 and enters the first gas outlet pipe 11 and the second gas outlet pipe 12 respectively. The first gas outlet pipe 11 and the second gas outlet pipe 12 guide the pressurized gas into the second three-way valve 23. The pressurized gas then enters the air inlet pipe 29 through the second three-way valve 23. The air inlet pipe 29 guides the pressurized gas into the brake mechanism, and the brake mechanism realizes braking.

[0060] When the second foot switch 35 is stepped on, the gas flow is as follows: the pressurized gas in the gas tank 5 is transported to the first three-way valve 14 through the gas main pipe 6, enters the second gas pipe 15 through the first three-way valve 14, enters the gas valve 16 through the second gas pipe 15, and then enters the third gas pipe 22 through the gas valve 16. The third gas pipe 22 introduces the pressurized gas into the second foot switch 35. The second foot switch 35 then introduces the pressurized gas into the fifth air outlet pipe 28 and the sixth air outlet pipe 30. The fifth air outlet pipe 28 and the sixth air outlet pipe 30 introduce the pressurized gas into the fourth three-way valve 27. The fourth three-way valve 27 then introduces the pressurized gas into the fourth air outlet pipe 25. The fourth air outlet pipe 25 introduces the pressurized gas into the third three-way valve 26. The third three-way valve 26 then introduces the pressurized gas into the air intake pipe 29. The air intake pipe 29 introduces the pressurized gas into the brake mechanism, and the brake mechanism realizes braking.

[0061] It should be noted that the first foot switch 10 and the second foot switch 35 can block the gas flow when they are not stepped on.

[0062] In some optional embodiments, a mounting structure of the control button is provided, such as Figure 1 As shown, a first support platform 3 and a second support platform 36 are additionally installed. The first support platform 3 is installed on the first cab 4 for supporting the installation of the first control button 2; the second support platform 36 is installed on the second cab 33 for supporting the installation of the second control button 37.

[0063] The first control button 2 is mounted on the first support platform 3 , so that the driver can operate the first control button easily.

[0064] The second control button 37 is mounted on the second support platform 26 , so that the driver can operate the second control button in the second cab.

[0065] In some embodiments, a structure of a moving mechanism is given, such as Figure 1 、 2As shown, the moving mechanism includes a first moving mechanism 21 and a second moving mechanism 32, the first moving mechanism 21 and the second moving mechanism 32 are installed on the bottom of the frame 39 in a spaced distribution, the first moving mechanism 21 is in transmission connection with the driving mechanism, and the second moving mechanism 32 is installed with a brake mechanism.

[0066] The first moving mechanism 21 includes a first running wheel 211, a first support shaft 212, a first connecting plate 213, and a first base 214, the first support shaft 212 is installed with the first running wheel 211 at both ends to form a first wheel pair group, a plurality of first wheel pair groups are arranged in parallel at intervals, both ends of the plurality of first wheel pair groups are installed with the first connecting plate 213, the first connecting plate 213 is installed with the first base 214, and the first base 214 is connected with the frame 39.

[0067] The second moving mechanism 32 includes a second running wheel 321, a second support shaft 322, a second connecting plate 323, and a second base 324, the second support shaft 322 is installed with the second running wheel 321 at both ends to form a second wheel pair group, a plurality of second wheel pair groups are arranged in parallel at intervals, both ends of the plurality of second wheel pair groups are installed with the second connecting plate 323, the second connecting plate 323 is installed with the second base 324, and the second base 324 is connected with the frame 39.

[0068] It should be noted that the first support shaft on the first wheel pair group is in rotary connection with the first connecting plate. The second support shaft on the second wheel pair group is in rotary connection with the second connecting plate.

[0069] As shown, Figure 2 A structure of the brake mechanism is given. The brake mechanism includes an air disc brake 31, a second support 46, and a brake disc 47; the brake disc 47 is fixedly installed on a second support shaft 322, the air disc brake 31 is close to the brake disc 47 and is installed on the frame 39 through the second support 46, and is used to movably clamp the brake disc 47.

[0070] It should be noted that the air disc brake can be a horizontal air disc brake. The air disc brake can be purchased in the market. The air disc brake 31 can include a gas bag 311, a piston, a spring, a caliper 312, and a friction plate, etc. The working mode is: the gas bag is filled with gas under pressure, the gas bag drives the piston to extend outward, the piston pushes the caliper, the caliper 312 drives the friction plate thereon to clamp the brake disc, and brake braking is realized, at the same time, the spring is stretched to produce elastic deformation. When the gas bag stops filling gas under pressure, that is, the gas bag is depressurized, the spring drives the caliper to elastically reset, and the brake braking is released.

[0071] The working mode of the brake mechanism is:

[0072] When the air pressure disc brake 31 obtains the pressurized gas, it performs the brake braking work, so it can clamp the brake disc 47, so that the brake disc speed is reduced, and then the moving mechanism speed connected with the brake disc is reduced, and the speed of the electric rail vehicle is reduced to realize deceleration to stop.

[0073] When the pressurized gas supply to the air pressure disc brake 31 is stopped, the air pressure disc brake 31 stops working and releases the brake on the brake disc.

[0074] It should be noted that the second support shaft on which the brake disc 47 is installed is in transmission connection between the two ends and the second running wheel. The transmission connection between the second support shaft and the second running wheel on both ends can be key connection or welding connection. It can be understood that the remaining second support shafts not installed with brake discs are in rotational connection or fixed connection with the second running wheels at both ends. The connection mode can be selected as needed.

[0078] The transmission member can be a transmission belt or a chain.

[0079] It should be noted that the first support shaft in transmission connection with the output end of the gearbox is in transmission connection with the first running wheel at both ends. Therefore, the first support shaft and the first running wheel can be in key connection or welding connection. It can be understood that when the gearbox drives the first support shaft to rotate, the first support shaft drives the first running wheel in transmission connection to rotate, and the first running wheel can roll along the track.

[0080] Working mode of the driving mechanism:

[0081] When the driving motor 181 is started, the driving motor 181 drives the driving wheel 182 to rotate, the driving wheel 182 drives the driven wheel 185 to rotate through the transmission part 183, the driven wheel 185 drives the input shaft 184 to rotate, the input shaft 184 drives the gearbox 186 to work, the gearbox 186 drives the first support shaft 212 on the first moving mechanism 21 to rotate, the first support shaft 212 drives the first running wheels installed on both ends to rotate, the first running wheels roll along the track, and the electric track vehicle of the utility model is realized to move along the track.
