Description

Technical Field

[0001] The invention belongs to the technical field of rail-road dual-purpose vehicle track-mounting, and in particular relates to a rail-road dual-purpose vehicle auxiliary alignment system and a rapid track-mounting method. Background Art

[0002] At present, in the field of road-rail dual-use vehicles, when the vehicle body is put on the track vertically (that is, the initial state of the vehicle body is basically perpendicular to the direction of the track), it is necessary to use the road-rail conversion device to clamp the track and then support the whole vehicle to rotate 90 degrees and make it parallel to the track. Finally, the vehicle is lowered to make the front and rear guide wheels clamp on the track to complete the operation. Figure 1 As shown, in the second step (such as Figure 2 As shown in the figure, the operator and the driver need to cooperate in adjusting the posture of the vehicle or the road-rail conversion device so that the road-rail conversion device can be inserted into the rails, which is time-consuming and laborious. Figure 3 When adjusting the rotation angle of the vehicle to align the front and rear guide wheels with the rails, the operator needs to observe the front guide wheels in front of the vehicle and the rear guide wheels in the rear to see if they are in the track. If the observation is not in place, derailment accidents may easily occur.

[0003] According to the theoretical steps of track operation, track operation requires the operator and the driver to cooperate to complete two alignments. During the first alignment, the driver drives the vehicle directly into place (the road-rail conversion device is just stuck in the rail state, Figure 2 ) is almost impossible, and the driver and operator need to cooperate to fine-tune the vehicle's status. Such adjustments often result in excessive adjustments and require re-alignment. The difficulty of this alignment method lies in the fact that both the vehicle and the road-rail conversion device must be adjusted. There is a high probability that the two adjustments will interfere with each other and affect each other, thus falling into an adjustment cycle, which is time-consuming and labor-intensive. During the second alignment, the entire vehicle rotates 90° and cannot ensure that the front and rear guide wheels are aligned with the rails ( Figure 3 ), the operator needs to observe and make fine adjustments (rotate the entire vehicle) to ensure that the front and rear guide wheels are aligned with the rails. There is also the possibility of over-adjustment during this alignment process, which requires readjustment.

[0004] The current method of getting on track is rather complicated and requires the cooperation of two people. Mistakes often occur and the vehicle cannot be put on track correctly, which places higher demands on operators and drivers. At the same time, this method cannot be applied to level crossing operations where the road-rail vehicle is at an angle (≠90°) to the rails. Summary of the invention

[0005] The invention overcomes the shortcomings of the prior art and provides an auxiliary alignment system for a road-rail dual-purpose vehicle and a rapid track-mounting method; the problem that the current road-rail dual-purpose vehicle requires the cooperation of two persons and is prone to errors when being track-mounted is solved.

[0006] In order to achieve the above object, the present invention is implemented through the following technical solutions.

[0007] A road-rail vehicle auxiliary alignment system, wherein a road-rail conversion device is arranged at the center of the lower end surface of the chassis of the road-rail vehicle, and the auxiliary alignment system comprises a controller, a display, a swivel camera, a track alignment camera, and a guide camera; the controller is installed inside the driving cab of the road-rail vehicle, the display is installed on the co-pilot side of the driving cab of the road-rail vehicle, the number of the swivel camera is one, and the one swivel camera is arranged at the center of the lower end surface of the road-rail conversion device, the number of the track alignment cameras is two, and the two track alignment cameras are respectively arranged at the left and right ends of the front edge of the lower end surface of the road-rail conversion device, and the number of the guide cameras is two, and the two guide cameras are respectively arranged at the middle of the front and rear edges of the lower end surface of the chassis of the road-rail vehicle.

[0008] Furthermore, a front guide device and a rear guide device are respectively arranged at the front and rear ends of the chassis of the road-rail vehicle, the front guide device includes two front guide wheels, and the rear guide device includes two rear guide wheels.

[0009] Furthermore, the minimum distance between the connection line of the two track cameras and the rotating camera is equal to half of the distance between the two rails.

[0010] Furthermore, the display images of the rotating camera, the track alignment camera, and the guide camera on the display all include a dotted circle and a solid circle, wherein the dotted circle is located outside the solid circle, and the dotted circle and the solid circle are arranged concentrically.

[0011] Furthermore, the dotted circle represents the visual range of the camera, and the radius of the dotted circle is determined by the parameters of the camera itself; the solid circle represents the accuracy range, and the radius of the solid circle = (inner width of the rail - width of the slot of the road-rail conversion device) / 2. As long as the target falls into the solid circle, it proves that the camera and the target are aligned.

[0012] Furthermore, the auxiliary alignment system also includes a centerline marking device, which includes a crossbeam, a laser, a bidirectional screw, a caliper, and a block; a hinged seat is fixedly provided at each end of the crossbeam, a bidirectional screw is rotatably provided between the two hinged seats, and the two sections of external threads on the outer side of the bidirectional screw have opposite rotation directions; a caliper is respectively screwed on the two sections of external threads on the outer side of the bidirectional screw, and both calipers maintain sliding contact with the crossbeam; a laser is fixedly provided in the middle of the crossbeam, and the two calipers are symmetrically provided relative to each other; two blocks are also fixedly provided on the crossbeam, the two blocks are rotatably sleeved on the outer side of the bidirectional screw, the two blocks are located between the two calipers, and the two blocks are symmetrically provided relative to the laser.

[0013] Furthermore, a method for quickly getting on track of a road-rail dual-purpose vehicle auxiliary alignment system comprises the following steps: The first step is to arrange a set of centerline identification devices between the two ends of the two rails of the level crossing, so as to form a centerline between the two rails of the level crossing; The second step is to drive the road-rail dual-use vehicle to the top of the level crossing and operate the road-rail dual-use vehicle so that the center line appears inside the solid circle of the rotating camera, indicating that the rotation center of the road-rail dual-use vehicle is aligned with the center line between the two rails; The third step is to observe the alignment of the two track cameras with the rails to determine whether the road-rail conversion device needs to be adjusted. If the two track cameras are aligned with one of the rails, there is no need to adjust the road-rail conversion device. If the two track cameras are not aligned with one of the rails, the road-rail conversion device needs to be adjusted until the two track cameras are aligned with one of the rails. The fourth step is to use the road-rail conversion device to support the road-rail dual-purpose vehicle and rotate it 90 degrees; Step 5: Operate the road-rail vehicle so that the center line appears within the solid loops of the front and rear guidance cameras, indicating that the road-rail vehicle is now completely aligned with the center lines of the two rails. Step 6: Use the road-rail conversion device to lower the road-rail dual-purpose vehicle so that the two front guide wheels and the two rear guide wheels are both engaged between the two rails, so that the road-rail dual-purpose vehicle as a whole is located on the two rails, and the road-rail conversion device is in a retracted state; The seventh step is to complete the track operation of the road-rail vehicle.

[0014] The beneficial effects of the present invention compared with the prior art are as follows: The invention provides an auxiliary alignment system for a road-rail dual-purpose vehicle and a rapid track-mounting method, which simplifies the process, saves track-mounting time, and avoids repeated adjustments; one person operates, reducing alignment failures caused by communication errors; and is suitable for the alignment process when the deflection angle between the vehicle and the rail direction is too large (not vertical).

DETAILED DESCRIPTION

[0016] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention is further described in detail in conjunction with the embodiments and the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. The technical solutions of the present invention are described in detail below in conjunction with the embodiments and the accompanying drawings, but the scope of protection is not limited thereto.

[0017] like Figure 5 As shown in FIG. 11 , the present invention provides an auxiliary alignment system for a road-rail dual-purpose vehicle, including a controller 6, a display 7, a rotating camera 8, a track alignment camera 9, a guide camera 10, and a center line 20 marking device.

[0018] A road-rail conversion device 3 is provided at the center of the lower end surface of the chassis 2 of the road-rail vehicle 1. The road-rail conversion device 3 is a prior art. The road-rail conversion device 3 can be used to lift and lower the body of the road-rail vehicle 1 as a whole, and can also be used to horizontally rotate the body of the road-rail vehicle 1 to adjust the horizontal angle of the body.

[0019] A front guide device 4 and a rear guide device 5 are respectively arranged at the front and rear ends of the chassis 2 of the road-rail dual-use vehicle 1. The front guide device 4 includes two front guide wheels, and the rear guide device 5 includes two rear guide wheels. When the body of the road-rail dual-use vehicle 1 is horizontally rotated by the road-rail conversion device 3, it is necessary to observe the alignment of the front guide wheels and the rear guide wheels with the two rails 19. When the two front guide wheels and the two rear guide wheels are successfully on the rails, the road-rail dual-use vehicle 1 completely completes the conversion from road to rail.

[0020] The controller 6 is installed inside the cab of the road-rail vehicle 1 , and the display 7 is installed on the co-pilot side of the cab of the road-rail vehicle 1 , so that the driver can directly observe the display conditions of all cameras from the display 7 .

[0021] There is one rotating camera 8 , which is disposed at the center of the lower end surface of the road-rail conversion device 3 . The rotating camera 8 is used to monitor whether the center of the road-rail vehicle 1 is aligned with the center line 20 between the two rails 19 .

[0022] There are two track-aligning cameras 9, which are respectively arranged at the left and right ends of the front edge of the lower end face of the road-rail conversion device 3. The minimum distance between the connecting line of the two track-aligning cameras 9 and the rotating camera 8 is equal to half of the distance between the two rails 19. The two track-aligning cameras 9 are used to monitor whether they are aligned with the two rails 19 respectively.

[0023] There are two guide cameras 10, which are respectively arranged in the middle of the front and rear edges of the lower end face of the chassis 2 of the road-rail vehicle 1. The front guide camera 10 is used to monitor whether the front end center of the chassis 2 of the road-rail vehicle 1 is aligned with the center line 20 between the two rails 19, and the rear guide camera 10 is used to monitor whether the rear end center of the chassis 2 of the road-rail vehicle 1 is aligned with the center line 20 between the two rails 19.

[0024] The display screens of the rotating camera 8, the rail camera 9, and the guide camera 10 on the display 7 all include a dotted circle 12 and a solid circle 11, wherein the dotted circle 12 is located outside the solid circle 11, and the dotted circle 12 is concentric with the solid circle 11. The dotted circle 12 represents the visual range of the camera, and the radius of the dotted circle 12 is determined by the parameters of the camera itself. The solid circle 11 represents the accuracy range, and the radius of the solid circle 11 = (inner width of the rail 19 - width of the slot of the road-rail conversion device 3) / 2. As long as the target falls into the solid circle 11, it proves that the camera and the target are aligned.

[0025] The center line 20 marking device includes a crossbeam 14, a laser 17, a bidirectional screw 15, a caliper 16, and a stopper 18. An articulated seat is fixedly provided at each end of the crossbeam 14, and a bidirectional screw 15 is rotatably provided between the two articulated seats, and the two sections of external threads on the outer side of the bidirectional screw 15 are rotated in opposite directions. A caliper 16 is screwed onto the two sections of external threads on the outer side of the bidirectional screw 15, and both calipers 16 maintain sliding contact with the crossbeam 14. A laser 17 is fixedly provided in the middle of the crossbeam 14, and the two calipers 16 are symmetrically provided relative to each other. Two stops 18 are also fixedly provided on the crossbeam 14, and the two stops 18 are rotatably sleeved on the outer side of the bidirectional screw 15, and the two stops 18 are located between the two calipers 16, and the two stops 18 are symmetrically provided relative to the laser 17.

[0026] When it is necessary to mark the center line 20 between two rails 19, two sets of center line 20 marking devices are respectively installed between the two ends of the two rails 19 of the level crossing 21. Before installation, the two-way screw 15 is rotated to make the two clamps 16 approach each other, ensuring that the distance between the two clamps 16 is less than the distance between the two rails 19. Then the crossbeam 14 is placed on the two rails 19 to ensure that the two clamps 16 are between the two rails 19, and then the two-way screw 15 is rotated in the opposite direction to make the two clamps 16 move away from each other until the two clamps 16 are stably clamped between the two rails 19, so that the center line 20 marking device is fixed between the two rails 19. After the two sets of center line 20 marking devices are installed, the two lasers 17 form a center line 20 between the two rails 19 of the level crossing 21, and the center line 20 is equal to the distance between the two rails 19.

[0027] like Figure 4 As shown, according to the above-mentioned auxiliary alignment system for a road-rail dual-purpose vehicle, a method for quickly getting on track of a road-rail dual-purpose vehicle 1 includes the following steps: In the first step, a set of centerline identification devices 13 are respectively arranged between the two ends of the two rails 19 of the level crossing 21, so as to form a centerline 20 between the two rails 19 of the level crossing 21; if there is no centerline identification device 13, the centerline of the rail can be marked by measuring and marking with a tool such as a tape measure; The second step is to drive the road-rail dual-use vehicle 1 to the top of the level crossing 21, and operate the road-rail dual-use vehicle 1 so that the center line 20 appears inside the solid coil 11 of the rotating camera 8, indicating that the rotation center of the road-rail dual-use vehicle 1 is aligned with the center line 20 between the two rails 19; The third step is to observe the alignment of the two track-aligned cameras 9 and the rails 19 to determine whether the road-rail conversion device 3 needs to be adjusted. If the two track-aligned cameras 9 are aligned with one of the rails 19, there is no need to adjust the road-rail conversion device 3. If the two track-aligned cameras 9 are not aligned with one of the rails 19, the road-rail conversion device 3 needs to be adjusted until the two track-aligned cameras 9 are aligned with one of the rails 19.

[0028] Step 4: Use the road-rail conversion device 3 to support the road-rail dual-purpose vehicle 1 and rotate it 90 degrees; Step 5: operate the road-rail vehicle 1 so that the center line 20 appears within the solid coils 11 of the front and rear guide cameras 10, indicating that the road-rail vehicle 1 is now completely aligned with the center lines 20 of the two rails 19; Step 6: Use the road-rail conversion device 3 to lower the road-rail dual-purpose vehicle 1, so that the two front guide wheels and the two rear guide wheels are both clamped between the two rails 19, so that the road-rail dual-purpose vehicle 1 is completely located on the two rails 19, and the road-rail conversion device 3 is in a retracted state; The seventh step is to complete the track operation of the road-rail dual-purpose vehicle 1.

[0029] The steps for vertically mounting the road-rail vehicle 1 are as follows: Fig.12 As shown: During the process of the road-rail vehicle 1 being put on the track, if the road-rail vehicle 1 is substantially perpendicular to the rail 19, the driver directly drives the road-rail vehicle 1 to the level crossing 21, and observes through the rotating camera 8 whether the center line 20 between the two rails 19 is within the dotted circle 12, thereby completing the rough alignment (key step G1); then, the road-rail vehicle 1 is adjusted (generally by moving the vehicle forward and backward) so that the center line 20 between the two rails 19 is within the solid circle 11 of the rotating camera 8, thereby completing the fine alignment.

[0030] Then observe whether the edge lines of the same rail 19 are all within the virtual circles 12 of the two track-aligning cameras 9, thereby completing the rough alignment (key step G2); then adjust the road-rail conversion device 3, and the road-rail conversion device 3 drives the road-rail dual-purpose vehicle 1 to rotate horizontally as a whole, so that the edge lines of the same rail 19 are all within the real circles 11 of the two track-aligning cameras 9, thereby completing the fine alignment.

[0031] Then, the road-rail conversion device 3 is used to lift the road-rail vehicle 1 as a whole and rotate it 90 degrees to observe whether the center line 20 between the two rails 19 is located within the virtual circle 12 of the front and rear guide cameras 10, thereby completing the rough alignment (key step G3); then the road-rail conversion device 3 is adjusted, and the road-rail conversion device 3 drives the road-rail vehicle 1 to rotate horizontally as a whole, so that the center line 20 between the two rails 19 is located within the real circle 11 of the front and rear guide cameras 10, thereby completing the fine alignment.

[0032] Then, the road-rail vehicle 1 is lowered using the road-rail conversion device 3, so that the two front guide wheels and the two rear guide wheels are both engaged between the two rails 19, so that the road-rail vehicle 1 as a whole is located on the two rails 19, and the road-rail conversion device 3 is in a retracted state; the track-mounting operation of the road-rail vehicle 1 is completed.

[0033] The steps of tilting the rail vehicle 1 onto the track are as follows: Fig.13 As shown: During the process of the road-rail vehicle 1 being put on the track, if the road-rail vehicle 1 is not perpendicular to the rail 19, then the angle between the surface road-rail vehicle 1 and the rail 19 is relatively large, and the driver directly drives the road-rail vehicle 1 to the level crossing 21, and observes through the rotating camera 8 whether the center line 20 between the two rails 19 is within the virtual circle 12, thereby completing the rough alignment (key step G1); then, by adjusting the road-rail vehicle 1 (generally a forward and backward moving vehicle), the center line 20 between the two rails 19 is within the solid circle 11 of the rotating camera 8, thereby completing the fine alignment.

[0034] Then observe whether the edge lines of the same rail 19 are all within the virtual circles 12 of the two track-aligning cameras 9, thereby completing the rough alignment (key step G2); then adjust the road-rail conversion device 3, which drives the road-rail dual-purpose vehicle 1 to rotate horizontally as a whole. The required horizontal rotation amplitude is relatively large, so that the edge lines of the same rail 19 are all within the real circles 11 of the two track-aligning cameras 9, thereby completing the fine alignment.

[0035] Then, the road-rail conversion device 3 is used to lift the road-rail vehicle 1 as a whole and rotate it 90 degrees to observe whether the center line 20 between the two rails 19 is located within the virtual circle 12 of the front and rear guide cameras 10, thereby completing the rough alignment (key step G3); then the road-rail conversion device 3 is adjusted, and the road-rail conversion device 3 drives the road-rail vehicle 1 to rotate horizontally as a whole, so that the center line 20 between the two rails 19 is located within the real circle 11 of the front and rear guide cameras 10, thereby completing the fine alignment.

[0036] Then, the road-rail vehicle 1 is lowered using the road-rail conversion device 3, so that the two front guide wheels and the two rear guide wheels are both engaged between the two rails 19, so that the road-rail vehicle 1 as a whole is located on the two rails 19, and the road-rail conversion device 3 is in a retracted state; the track-mounting operation of the road-rail vehicle 1 is completed.
