Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings, in order to make the objects, technical solutions and advantages of the present invention more apparent.
Example 1
As shown in fig. 1,2 and 3, the self-propelled wheeltrack rack transport flatcar disclosed in the present embodiment includes a track flatcar and a track, and the track flatcar includes a car body 28 and a bogie.
The track flatcar in this embodiment comprises two bogies on which the car body 28 is supported. Each bogie comprises a front and a rear travelling mechanism and a frame, each frame comprising two double frames 15 and a single frame 19, the two travelling mechanisms being mounted on one of the double frames 15 respectively. Two radial dampers 27 are arranged between the two-layer frames 15 in a crossing way, and two ends of each radial damper 27 are respectively hinged with one of the two-layer frames 15. Providing radial dampers 27 may increase the binding force. For example, during cornering, the speed of the outer wheels is adjusted to be high, the speed difference between the inner and outer wheels is increased, and the radial dampers 27 tend to reduce the speed difference, thereby making the vehicle run more smoothly and safely. Since the radial damper 27 makes the constraint force stronger, the motor should be selected to have a strong overload resistance.
The first layer of frame 19 is located above two layers of frames 15, and two ends of the first layer of frame 19 are respectively connected with one of the two layers of frames 15 through spherical hinges 23. As shown in fig. 2 and 3, hinge seats 24 are provided at corresponding positions of the first-layer frame 19 and the second-layer frame 15. Damping devices are arranged between the first layer of frameworks 19 and the second layer of frameworks 15, and each damping device comprises a series of damping springs 16, a first transverse damper 25 and a vertical damper 26. Four primary damping springs 16 are arranged above each two-layer framework 15, and the primary damping springs 16 can be rubber dampers.
Of course, as shown in FIG. 2, the truck also includes a second transverse damper 17, a vertical damper 18, a secondary damper spring 20, an anti-serpentine damper 21, and a traction rod 22. The second transverse damper 17, the vertical damper 18, the secondary damper springs 20, the antiwind damper 21 and the traction rod 22 are mounted on a one-layer frame 19 for connection with the vehicle body 28.
As shown in fig. 1 and 4, the travelling mechanism comprises two travelling units which are symmetrically arranged left and right. The walking unit comprises a driving motor 3, a walking wheel 6, a driving gear 12, a first clutch 5, a second clutch 9, a transverse shaft 2, a vertical shaft 11, a driving bevel gear 7 and a driven bevel gear 10 which are meshed with each other, wherein the driving bevel gear 7 is fixedly arranged at one end of the transverse shaft 2, and the other end of the transverse shaft 2 is connected with a brake disc 1. The transverse shaft 2 is connected with a driving motor 3. In order to increase torque at low speed, the drive motor 3 supplies drive force in cooperation with the planetary reducer 4.
The driving gear 12 is fixedly arranged at the lower end of the vertical shaft 11, and the upper end of the vertical shaft 11 is connected with the brake 8. The drive gear 12 is located between the two road wheels 6.
The travelling wheel 6 is sleeved on the transverse shaft 2 through a bearing or a bearing bush, and the travelling wheel 6 is in transmission with the transverse shaft 2 through the first clutch 5. The main body of the first clutch 5 is mounted on the transverse shaft 2. When the first clutch 5 is engaged, the transverse shaft 2 drives the travelling wheels 6 to rotate together; when the first clutch 5 is opened, the road wheel 6 does not actively rotate.
The driven bevel gear 10 is sleeved on the vertical shaft 11 through a bearing or a bearing bush, the driven bevel gear 10 and the vertical shaft 11 are driven through the second clutch 9, and the main body of the second clutch 9 is arranged on the vertical shaft 11. When the second clutch 9 is engaged, the driven bevel gear 10 drives the vertical shaft 11 to rotate together; when the second clutch 9 is disengaged, the vertical shaft 11 does not actively rotate.
In this embodiment, the first clutch 5 and the second clutch 9 are friction clutches. A hydraulic clutch, an electromagnetic clutch, or a pneumatic clutch may be selected.
The track comprises two rails 13, a toothed rail 14 arranged between the two rails 13. As shown in fig. 1 and 4, the toothed rail 14 is located on the midline of the rail plate beam between the two rails 13. The rack 14 in this embodiment comprises an i-steel 142 and two racks 141; the two racks 141 are respectively installed at both sides of the web of the i-steel 142, and the i-steel 142 is positioned on the middle line of the rail plate beam between the two rails 13. The two travelling wheels 6 travel on one of the rails 13 respectively, and the two driving gears 12 are meshed with one of the racks 141 respectively. The two driving gears 12 are meshed with the racks 141 on the I-steel 142 to walk, and the climbing capacity is greatly improved through a mechanical force transmission structure.
The tooth surface of the rack 141 does not exceed the upper flange of the i-beam 142, so that the gear teeth are restrained in the upper flange range of the i-beam 142. For example, if the travelling wheel on one side has a tendency to derail during turning, the driving gear 12 on the side can be limited by the upper flange of the i-steel 142, so that the driving gear 12 on the side is prevented from being separated from the rack, and then the track flatcar is prevented from jumping teeth to derail, and the running safety is ensured.
The working principle of the invention is described below with reference to fig. 4:
When the track flatcar runs on the toothless track section. At this time, it is necessary to switch to the wheel-rail drive mode. The second clutch 9 is first disengaged and then the first clutch 5 is engaged. The driving motor 3 drives the transverse shaft 2 to rotate, the transverse shaft 2 rotates to drive the brake disc 1 fixedly connected with the transverse shaft 2, the driving bevel gear 7 and the first clutch 5 to rotate simultaneously, and the first clutch 5 drives the travelling wheel 6 to rotate due to the attraction of the first clutch 5, so that wheel rail driving is realized.
Since the second clutch 9 is disengaged, the drive bevel gear 7 drives the driven bevel gear 10 to idle, and the vertical shaft 11 and the driving gear 12 do not rotate. This feature allows it to enter the rack smoothly when entering the ramp section. The structure is suitable for a road section.
When the track flatcar runs on the toothed track section and the wheel-rail driving mode is selected, the second clutch 9 is disconnected, and then the first clutch 5 is closed. The driving motor 3 drives the cross shaft 2 to rotate, the cross shaft 2 rotates to drive the brake disc 1 fixedly connected with the cross shaft 2, the driving bevel gear 7 and the first clutch 5 to rotate simultaneously, and as the first clutch 5 is attracted, the first clutch 5 drives the travelling wheel 6 to rotate, so that wheel rail driving is realized;
since the second clutch 9 is disconnected, the driving bevel gear 7 drives the driven bevel gear 10 to idle, at this time, the traveling wheel 6 is a driving wheel, the driving gear 12 is driven by the friction force of the toothed rail 12, and simultaneously drives the vertical shaft 11 to idle. This mode is suitable for operation on flat slopes.
When the track flatcar runs on the toothed rail section and needs to be switched to the toothed rail driving mode. The first clutch 5 is disconnected and the second clutch 9 is then closed. The driving motor 3 drives the transverse shaft 2 to rotate, the transverse shaft 2 rotates to drive the brake disc 1 fixedly connected with the transverse shaft 2, the driving bevel gear 7 and the first clutch 5 to rotate simultaneously, and the travelling wheel 6 is not actively sleeved on the transverse shaft 2 due to the disconnection of the first clutch 5.
The drive bevel gear 7 meshes with the driven bevel gear 10. The driving bevel gear 7 drives the driven bevel gear 10 to rotate, and the second clutch 9 drives the vertical shaft 11 to rotate due to the attraction of the second clutch 9, so that the driving gear 12 fixedly connected on the transverse shaft 10 is driven to rotate. The driving gear 12 is meshed with the toothed rail 12 so as to drive the whole motion, at the moment, the driving gear 12 is a driving wheel, and the travelling wheel 6 is driven by the friction force of the steel rail 13.
The driving of the invention adopts a wheel rail driving system and a gear rack driving system; the 40%slope section can be driven by a wheel rail; the 40-500 mill slope section can be driven by a gear rack. The car body 28 is additionally provided with an industrial wireless remote control device, and the running of the car body can be automatically switched between the wheel rail driving and the toothed rail driving through remote control running. The wheel rail drive and the toothed rail drive share one power source, and the wheel rail drive and the toothed rail drive are switched by firstly disconnecting one clutch and then connecting the other clutch, so that the device is suitable for running on any road section.
In the embodiment, the driving motor 3 is arranged radially and is suitable for the rail flat car with wider width. When the width of the rail flatcar is insufficient, the driving motor 3 is arranged below the transverse shaft 2, and the driving motor 3 and the transverse shaft 2 are in meshed transmission through a pair of gears. The size of the rail flatcar is set according to the requirement. For example, the rail flat car is 19.2 meters long, 2.5 meters wide and 1.6 meters high.
The power source of the rail flat car can adopt clean energy methanol as fuel, so as to realize the environment-friendly power sources of a micro-gas engine generator and a super capacitor. A dedicated third rail power supply may also be used.
In order to enable the rail vehicle to be firmly stopped on the ramp. The self-propelled wheel-rail toothed rail transport flat car also comprises a locking mechanism for locking the rail flat car and the rail. On the ramp, the car body 28 is locked with the steel rail 13 through a locking mechanism after the car body 28 is parked, so that the car body 28 is static and is prevented from reversing. As shown in fig. 6, the locking mechanism in this embodiment includes a rail clamp 29, and the rail clamp 29 is mounted on the bogie frame 15.
