Detailed implementation mode

[0023] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Apparently, the described embodiments are some but not all of the embodiments of the present utility model. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] In the description of this specification, references to the terms "one embodiment", "some embodiments", "illustrative embodiments", "examples", "specific examples", or "some examples", etc. mean that the specific features, structures, materials, or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present utility model. In the present utility model, the schematic expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0025] Refer to Figure 1 , this embodiment provides a rail-mounted passenger car for transporting personnel of a toothed-rail rail-mounted vehicle. The track on which the toothed-rail rail-mounted vehicle runs includes a rack portion in the middle for meshing with the gear of the toothed-rail driving part and two special-shaped rails arranged oppositely on both sides of the rack portion. The wheels on both sides of the toothed-rail rail-mounted vehicle run on the special-shaped rails.

[0026] The rail-mounted passenger car of this embodiment mainly includes a car body 1, an underframe 2, and a bogie 3.

[0027] Among them, a number of seats are arranged in the car body 1. The whole car body 1 is installed on the underframe 2. There are two bogies 3, which are connected to the front and rear parts of the bottom of the underframe. Through the bogie 3, the rail-mounted passenger car can run smoothly on the track, and can well adapt to the slope change and turning of the track together with the wheels 36. Moreover, a braking device is provided on the bogie, and the safety performance is high.

[0028] Refer to Figure 3, in some possible embodiments, the bogie includes a main shaft 38 and wheel brackets 39 rotatably connected to both ends of the main shaft 38. A wheel 36 is respectively installed at both ends of the wheel bracket 39. The wheel 36 travels on the top surface of the special-shaped rail. A turntable 37 is provided in the middle of the main shaft, and the turntable 37 is rotatably connected below the underframe 2.

[0029] Reference Figure 3 and Figure 4 , an upper braking device is installed on the wheel bracket 39 at a position between the two wheels 36. The upper braking device includes a driving member 35 and an upper brake block 34 connected to the driving member 35. The driving member 35 is used to drive the upper brake block 34 to press against the top surface of the special-shaped rail 4 to achieve braking.

[0030] In some possible embodiments, the driving member 35 can be a hydraulic cylinder. Of course, other possible structures can also be selected, such as a cylinder or an electric push rod, etc. In this embodiment, the axis of the hydraulic cylinder is perpendicular to the top surface of the special-shaped track 4, and the upper brake block 34 is pressed against the top surface of the special-shaped rail 4 by the positive pressure of the hydraulic cylinder.

[0031] Optionally, the hydraulic cylinder can adopt the oil cylinder disc spring braking method, which has a large braking force and a fast braking speed.

[0032] Reference Figure 2 and Figure 4 , a lower braking device is connected to the outer end of the axle of each wheel 36. The lower braking device includes a connecting frame 33 and a lower brake block 32. The lower brake block 32 is fixed to the lower end of the connecting frame 33, and the lower brake block 32 extends into the space S below the outer side roof plate of the special-shaped rail 4.

[0033] That is to say, the lower brake block 32 can be used as a rail clamping member on the one hand and a braking member on the other hand.

[0034] When the rail clamping manrider needs to be braked, by starting each hydraulic cylinder, the hydraulic cylinder pushes the upper brake block 34 to press against the top surface of the special-shaped rail 4 and lifts the rail clamping manrider to a certain height. At this time, the lower brake block 32 below the roof plate of the special-shaped rail is closely attached to the lower surface of the roof plate of the special-shaped rail, and the upper brake block 34 and the lower brake block 32 jointly press the roof plate of the special-shaped rail 4, thereby realizing the braking of the rail clamping manrider. The braking method of clamping the special-shaped rail up and down has a short braking distance, greatly shortens the relative sliding distance of the mine manrider, has a good braking effect, and is safe and reliable.

[0035] In some possible embodiments, a guide wheel 31 is further provided at the lowermost part of the connecting frame 33. The guide wheel 31 is provided below the lower brake block 32, and the guide wheel 31 is also provided in the space S below the roof plate. The guide wheel 31 can be in contact with the web of the special-shaped rail 4 to play a guiding role.

[0036] In some possible embodiments, a centrifugal speed limiting component 5 is provided on the wheel swing frame 39 of one of the bogies, and the speed measuring wheel of the centrifugal speed limiting component 5 abuts against the top surface of the special-shaped rail 4. Through the speed taking of the speed measuring wheel of the centrifugal speed limiting component 5, when the speed exceeds the limit, the trigger pin in the centrifugal speed limiting mechanism is thrown out under the action of centrifugal force, and the trigger pin then pushes the lever that abuts against the switch of the brake control valve, so that the hydraulic cylinder is depressurized for braking. Through this centrifugal speed limiting component 5, automatic speed limiting braking (automatically triggering braking when the running speed exceeds the limited speed) can be realized.

[0037] In some embodiments, a small hydraulic station 6 is configured on the carriage, and each hydraulic cylinder is supplied with oil through the hydraulic station 6.

[0038] In some embodiments, a plurality of shock pads 7 are provided between the carriage 1 and the underframe 2.

[0039] When this embodiment is specifically used, during the running process, the hydraulic cylinder is pressurized by the hydraulic station 6, the disc spring in the hydraulic cylinder is compressed, and the upper brake block 34 is lifted by the piston rod to completely open the braking device (detach from the track); when the running speed of the rail clamping personnel carrier exceeds the set speed, the trigger pin of the centrifugal speed limiting component 5 will be thrown out, and drive the lever to rotate to disengage the roller of the brake control valve, so that the brake control valve is opened, thereby causing each hydraulic cylinder to be depressurized, the disc spring to return, driving the upper brake block 34 to press against the rail surface, and at the same time the lower brake block 31 is lifted to realize the clamping of the upper and lower brake blocks to the rail for braking.

[0040] In another embodiment, the present utility model further includes a toothed rail clamping vehicle. The rail clamping personnel carrier is connected to other components of the toothed rail clamping vehicle through a pull rod and is used for transporting personnel of the toothed rail clamping vehicle. Since the rail clamping personnel carrier has a brake and adopts a structure of a lower braking device that can clamp the rail, its rail clamping performance and braking performance are both good.

[0041] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model and are not intended to limit them; although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or modify some or all of the technical solutions, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present utility model.
