Description

Technical Field

[0001] The utility model relates to rail transit, and particularly to a rail and road dual-purpose rail welding vehicle. Background Art

[0002] The rail and road dual-purpose rail welding vehicle is usually used to switch the wheel pair mode or the tire mode in the crossover area (the intersection area of the rail and the road). After the switching, it either travels on the rail by using the wheel pair system or travels on the road by using the tire system.

[0003] In the existing dual-purpose vehicles, the switching needs to be carried out in the crossover area. However, the places where the rails need to be repaired may be far away from the crossover area. The dual-purpose vehicle travels a long distance on the rail, resulting in low efficiency. On the other hand, if the wheel pair system or the tire system is directly switched at the repair place, the tire system will roll on the ballast bed, affecting the repair effect. Although the wheel pair system or the tire system can be switched with the support of both sides of the ballast bed, the lateral width of the tire system needs to be adjusted to be greater than the width of the ballast bed, which will cause the dual-purpose vehicle to be too wide and difficult to enter the tunnel or go underground when repairing the rails in the subway or tunnel. Summary of the Utility Model

[0004] The utility model provides a rail and road dual-purpose rail welding vehicle, the purpose of which is to provide a horizontally translatable rail and road dual-purpose rail welding vehicle, and the whole vehicle is moved onto the rail or under the rail by using a support translation system perpendicular to the length direction of the rail.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0029] In order to make the technical problems, technical solutions and advantages to be solved by the present utility model clearer, the following will be described in detail with reference to the drawings and specific embodiments.

[0030] As Figures 1-5 shown, an embodiment of the present utility model provides a rail and road dual - purpose rail welding vehicle, including a frame chassis 1. Below the frame chassis 1, a tire system 2, a wheel set system 3 and a support translation system 4 are respectively arranged. Among them, the tire system 2 is fixedly arranged on the frame chassis 1. The tire system 2 has tires. In the tire mode, the tires drive the frame chassis 1 to move. In the present application, the installation scheme of the tire system 2 on the frame chassis 1 can refer to the installation method of existing automobiles. The wheel set system 3 is arranged on the frame chassis 1, and the wheel set system 3 can be lifted and lowered in the height direction of the frame chassis 1. In the wheel set mode, the wheel set 32 contacts the rail and travels on the rail. It should be emphasized that in the wheel set mode, a tractor is required for traction to achieve traveling in the wheel set mode.

[0031] The foregoing support translation system 4 includes a sleeve 41 provided on the frame chassis 1. The length direction of the sleeve 41 is arranged along the width direction of the frame chassis 1. Two telescopic structures 42 that can be telescoped along the length direction of the sleeve 41 are arranged inside the sleeve 41. One end of the two telescopic structures 42 is located inside the sleeve 41, and the other end forms a free end outside the two ends of the sleeve 41. A first support structure 43 is provided at the free ends of the two telescopic structures 42. The first support structure 43 is used to support the telescopic structure 42 along the height direction of the frame chassis 1. A second support structure 44 is provided on the sleeve 41. The second support structure 44 supports the sleeve 41 along the height direction of the frame chassis 1.

[0032] In this application, at the position where it is necessary to move onto or off the rail, through the telescoping of the telescopic structure 42 and the alternating supports of the first support structure 43 and the second support structure 44, the frame chassis 1 can be moved in the direction perpendicular to the length of the rail. At the same time, when the support translation system 4 is not in use, it can be stored under the frame chassis 1, and it will not increase the width of the rail welding vehicle for both railway and road use. When in a tunnel or underground, the telescopic length of the support translation system 4 can be adjusted according to the size of the working space, and it can be laterally moved repeatedly for multiple times to achieve the purpose of moving onto or off the rail.

[0033] Further, the telescopic structure 42 includes a transverse movement oil cylinder 421 and a transverse movement sleeve 422. Two transverse movement oil cylinders 421 are arranged inside the sleeve 41. The fixed end of one of the transverse movement oil cylinders 421 can be hinged to the sleeve 41 to form a fixed end, and the other end can be telescoped along the length direction of the sleeve 41, which is defined as the telescopic end. The telescopic end is hinged to a transverse movement sleeve 422. The fixed end of the other transverse movement oil cylinder 421 is also hinged to the sleeve 41 to form a fixed end, and the telescopic end is hinged to the other transverse movement sleeve 422. Under the action of the two transverse movement oil cylinders 421, the two telescopic ends of the two transverse movement sleeves 422 can be telescoped from the two directions of the sleeve 41 respectively. The foregoing first support structure 43 is respectively arranged on the two transverse movement sleeves 422.

[0034] Preferably, the two transverse movement sleeves 422 and the sleeve 41 are both rectangular. The two transverse movement sleeves 422 are arranged inside the sleeve 41 along the length direction of the frame chassis 1, and when the transverse movement oil cylinders 421 are fully retracted, the two transverse movement sleeves 422 have an overlapping distance S.

[0035] In this embodiment, the transverse movement sleeve 422 is rectangular. When the telescopic ends of the two transverse movement oil cylinders 421 extend to the maximum distance, the transverse movement sleeve 422 can still support the frame chassis 1 to ensure the safety of the frame chassis 1.

[0036] Further, the first support structure 43 is rotatably arranged on the transverse movement sleeve 422, and the second support structure 44 is rotatably arranged on the sleeve 41.

[0037] In this embodiment, a rotating shaft is provided on one side of the transverse movement sleeve 422 close to the free end of the telescopic structure 42. The first support structure 43 is arranged on the rotating shaft, so that the first support structure 43 can be driven to rotate under the action of the rotating shaft. Similarly, a hinge seat is arranged on the sleeve 41, and the second support structure 44 is connected to the hinge seat. The second support structure 44 is driven to rotate under the action of the hinge seat.

[0038] Correspondingly, drag chains 45 are respectively arranged on the first support structure 43 and the second support structure 44. One end of each drag chain 45 is fixed on the vehicle frame chassis 1, and the other ends are detachably connected to the first support structure 43 and the second support structure 44 respectively.

[0039] When the rail and road dual-purpose rail welding vehicle is traveling, the first support structure 43 and the second support structure 44 are pulled by the drag chains 45, so that the included angle between the first support structure 43 and the second support structure 44 and the height of the vehicle frame chassis 1 is a right angle, avoiding the first support structure 43 and the second support structure 44 interfering with the traveling of the rail and road dual-purpose rail welding vehicle. When it is necessary to get on or off the rail, the drag chains 45 are loosened. At this time, the included angle between the first support structure 43 and the second support structure 44 and the height of the vehicle frame chassis 1 is zero, and the vehicle frame chassis 1 can be supported.

[0040] Preferably, at least two support translation systems 4 are provided, and multiple groups of support translation systems 4 are arranged along the length direction of the vehicle frame chassis 1.

[0041] Preferably, the first support structure 43 and the second support structure 44 are hydraulic cylinders.

[0042] In this application, the wheel set system 3 is also optimized. Specifically, the wheel set system 3 includes a pair of axle box suspensions 31. A wheel set shaft is inserted on the two axle box suspensions 31, and wheel sets 32 are arranged at both ends of the wheel set shaft. Under the action of the wheel set shaft, the two wheel sets 32 can travel under the action of a tractor. A lifting structure 33 is arranged at the upper end of each axle box suspension 31. The lifting structure 33 drives the axle box suspension 31 to lift in the height direction of the vehicle frame chassis 1, facilitating the switching of the wheel set system 3.

[0043] In this embodiment, when it is necessary to switch the wheel set system 3 or the tire system 2, the lifting structure 33 rises or falls to achieve rapid switching. Specifically, when it is necessary to switch from the tire system 2 to the wheel set system 3, first, the vehicle is moved to directly above the rail through the support translation system 4, and then the wheel set system 3 moves downward until the wheel sets 32 contact the rail. When it is necessary to switch from the wheel set system 3 to the tire system 2, first, the vehicle is moved from directly above the rail to the side through the support translation system 4, and then the wheel set system 3 moves upward to avoid the wheel set system 3 being higher than the tire system 2 when the tire system 2 contacts the ground and interfering with the traveling of the tire system 2 on the ground.

[0044] Further, a guiding structure 34 is also provided on each axle box suspension 31. The guiding structure 34 includes a guiding column 341 and a guiding cylinder 342. The guiding column 341 is fixed on the axle box suspension 31 and extends along the height direction of the vehicle frame chassis 1. The guiding cylinder 342 is arranged on the vehicle frame chassis 1 and also extends along the height direction of the vehicle frame chassis 1. The guiding column 341 can slide within the guiding cylinder 342, thus playing a guiding role.

[0045] Preferably, two guiding structures 34 are provided. The two guiding structures 34 on each axle box suspension 31 are symmetrically arranged with respect to the axle box suspension 31, and the two guiding structures 34 are arranged along the length direction of the vehicle chassis.

[0046] In the present application, at least two wheel set systems 3 are provided, and the multiple wheel set systems 3 are arranged along the length direction of the vehicle frame chassis 1.

[0047] Preferably, the lifting structure 33 is a hydraulic cylinder.

[0048] Preferably, in the present application, a rail welding device is also provided on the vehicle frame chassis 1.

[0049] Based on the same utility model purpose, the present application also provides a switching method for a rail and road dual-purpose rail welding vehicle. Using the aforementioned rail and road dual-purpose rail welding vehicle for vehicle up and down rail switching, it includes the following steps:

[0050] S11. When it is necessary to confirm whether there is a lateral movement space on one side of the track at the position of the up and down rail.

[0051] S12. After confirming that there is a lateral movement space on one side, the second support structure 44 moves downward and jacks up the vehicle frame chassis 1. At this time, the two lateral movement sleeves 422 and the lateral movement cylinders 421 are only affected by their own gravity and friction, and can slide easily.

[0052] S13. The telescopic structure 42 on the side close to the lateral movement space extends out of the sleeve 41, and the telescopic structure 42 on the side far from the lateral movement space retracts into the sleeve 41.

[0053] S14. The first structure extends downward and contacts the ground. After contact, the second support structure 44 retracts upward. At this time, the weight of the whole vehicle is supported by the first support structure 43.

[0054] S15. The telescopic structure 42 on the side close to the lateral movement space retracts into the sleeve 41, and the telescopic structure 42 on the side far from the lateral movement space extends out of the sleeve 41. At this time, driven by the two telescopic structures 42, the vehicle body moves in the direction of the lateral movement space.

[0055] S16. When the telescopic structure 42 reaches its stroke, the second support structure 44 extends downward and contacts the ground. After contact, the first support structure 43 retracts upward. Repeat steps S12 - S16 until the rail welding vehicle moves onto or under the rail. When moving onto the rail, the wheel set system 3 moves downward so that the wheel set 32 contacts the rail; when moving under the rail, the wheel set system 3 moves upward to avoid interfering with the contact between the tire system 2 and the ground.

[0056] The above are the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
