In addition, it should be noted that terms such as "first", "second", and the like are used for distinguishing one element from another, and have no order or importance.

Referring to fig. 1 to 6, the present disclosure provides a track beam maintenance vehicle 1 including: the track type rail vehicle comprises a vehicle body 10, road wheels 20, a driving wheel assembly 30 and a movement driving assembly 40, wherein the road wheels 20 comprise a first road wheel 21 and a second road wheel 22 which are arranged at intervals along the length direction of the vehicle body 10, the first road wheel 21 and the second road wheel 22 are both rotatably mounted on the vehicle body 10 and are used for being in rolling contact with the upper surface of a track beam of the track driving wheel assembly 30, the driving wheel assembly 30 comprises a driving wheel 31 and a first motor 32, the driving wheel 31 is positioned between the first road wheel 21 and the second road wheel 22, the driving wheel 31 is rotatably and movably mounted on the vehicle body 10 along the length direction of the vehicle body 10, the first motor 32 is connected to the driving wheel 31 and can move along the length direction of the vehicle body 10 along with the driving wheel 31, the first motor 32 is arranged to be capable of selectively driving the driving wheel 31 to rotate forwards or backwards, and the movement driving assembly 40 is mounted on the vehicle body 10 and is used for driving the driving wheel 31 to move along the length direction of the vehicle body 10.

Through the above technical solution, in the process that the service personnel rides the track beam maintenance vehicle 1 to travel on the track beam 100, when the first motor 32 of the driving wheel assembly 30 rotates forward, the driving wheel 31 can be driven to rotate forward, so as to drive the track beam maintenance vehicle 1 to travel on the track beam 100 in the forward direction (i.e. to travel in the first direction parallel to the length direction of the track beam 100, as shown in fig. 1), when the traveling direction of the track beam maintenance vehicle 1 needs to be adjusted, the moving driving assembly 40 can move the driving wheel 31 along the length direction of the vehicle body 10 before driving the driving wheel 31, and since the first motor 32 is connected to the driving wheel 31 and can move along the length direction of the vehicle body 10 together with the driving wheel 31, the moving driving assembly 40 can drive the driving wheel 31 and the first motor 32 to move along the length direction of the vehicle body 10 at the same time, and then the first motor 32 drives the driving wheel 31 to rotate in the reverse direction, so as to drive the track maintenance vehicle to travel on the track beam 100 in the reverse direction (i.e. to travel in the second direction parallel to the length direction of the track beam 100, as shown in fig. 2), so as shown in fig. 2, the track beam 1, the maintenance vehicle can be achieved.

In the above process, just before the first motor 32 drives the driving wheel 31 to rotate forward and backward, the movement driving assembly 40 can adaptively drive the driving wheel 31 and the first motor 32 to move along the length direction of the vehicle body 10, so that the driving wheel 31 can be effectively prevented from interfering or interfering with the sight of the maintenance personnel, and the driving and maintenance operations of the maintenance personnel on the track beam 100 on the track beam maintenance vehicle 1 can be facilitated.

Specifically, defined as the state when the track beam maintenance vehicle 1 is traveling in the forward direction, one end of the track beam maintenance vehicle 1 near the forward direction is a front end, and one end of the track beam maintenance vehicle near the rearward direction is a rear end, as shown in fig. 1, when the track beam maintenance vehicle 1 is traveling in the forward direction (i.e., when the first motor 32 drives the traveling wheels 20 to rotate in the forward direction), the first motor 32 and the driving wheels 31 may be located at the rear end of the track beam maintenance vehicle 1, at this time, with respect to the maintenance person, the first motor 32 and the driving wheels 31 are both located in the direction opposite to the traveling direction of the track beam maintenance vehicle 1, that is, as shown in fig. 1, the track beam maintenance vehicle 1 travels to the right side in the drawing direction of fig. 1, the maintenance person is located to the right side in the drawing direction of fig. 1, and the driving wheels 31 are located to the left side in the drawing direction of fig. 1, so that the driving wheels 31 do not interfere or interfere with the line of sight of the maintenance person; when the track beam inspection vehicle 1 needs to turn, that is, when the track beam inspection vehicle 1 travels in the reverse direction as shown in fig. 2, the moving drive assembly 40 may move the drive wheel 31 and the first motor 32 to the front of the track beam inspection vehicle 1, and similarly, with respect to the inspection person, the first motor 32 and the drive wheel 31 are both located in the direction opposite to the traveling direction of the track beam inspection vehicle 1, that is, when the track beam inspection vehicle 1 travels to the left side in the drawing direction of fig. 2 as shown in fig. 2, the inspection person is located to the left side in the drawing direction of fig. 2, and the drive wheel 31 is located to the right side in the drawing direction of fig. 2, so that when the track beam inspection vehicle 1 travels in the reverse direction, the drive wheel 31 does not interfere with or interfere with the line of sight of the inspection person.

As shown in fig. 3 and 5, optionally, in an embodiment provided by the present disclosure, the movement driving assembly 40 may include a first telescopic structure and a second telescopic structure, the driving wheel assembly 30 further includes a wheel axle 33, the driving wheel 31 is sleeved on the wheel axle 33, the first telescopic structure and the second telescopic structure are arranged at intervals along a length direction of the vehicle body 10 and are respectively located at two sides of the wheel axle 33, when the first telescopic structure extends, the first telescopic structure can contact the wheel axle 33 and push the wheel axle 33 and the driving wheel 31 to move in a direction close to the second telescopic structure, and when the second telescopic structure extends, the second telescopic structure can contact the wheel axle 33 and push the wheel axle 33 and the driving wheel 31 to move in a direction close to the first telescopic structure.

In another embodiment provided by the present disclosure, the moving driving assembly 40 may include a second motor 41, a transmission belt 42, a first transmission wheel 43, a second transmission wheel 44 and a moving wheel 45, the first transmission wheel 43 and the second transmission wheel 44 are oppositely disposed along the length direction of the vehicle body 10, the second motor 41 is fixed to the vehicle body 10, the first transmission wheel 43 is connected to an output shaft of the second motor 41, the second transmission wheel 44 is rotatably connected to the vehicle body 10, and the transmission belt 42 is wound on the first transmission wheel 43 and the second transmission wheel 44; the driving wheel assembly 30 further includes a wheel shaft 33, one of the driving wheel 31 and the moving wheel 45 is rotatably sleeved on the wheel shaft 33, the other of the driving wheel 31 and the moving wheel 45 is fixedly sleeved on the wheel shaft 33, and the moving wheel 45 is located between the first driving wheel 43 and the second driving wheel 44 and connected to the transmission belt 42, so that the transmission belt 42 can drive the moving wheel 45 to move along the length direction of the vehicle body 10. Before the track beam maintenance vehicle 1 needs to change direction, the second motor 41 rotates and drives the first transmission wheel 43 connected to the output shaft of the second motor 41 to rotate, and the transmission belt 42 is wound on the first transmission wheel 43 and the second transmission wheel 44, so that under the rotation of the first transmission wheel 43, the transmission belt 42 can be driven to rotate around the first transmission wheel 43 and the second transmission wheel 44, and the moving wheel 45 located between the first transmission wheel 43 and the second transmission wheel 44 is driven to move, so that the moving wheel 45 moves in the length direction of the vehicle body 10, and the driving wheel 31 connected to the wheel shaft 33 is driven to move in the length direction of the vehicle body 10, and the position of the driving wheel 31 is changed.

Because one of the driving wheel 31 and the moving wheel 45 is rotatably sleeved on the wheel shaft 33, and the other of the driving wheel 31 and the moving wheel 45 is fixedly sleeved on the wheel shaft 33, in the process that the first motor 32 drives the driving wheel 31 to rotate, the driving wheel 31 and the moving wheel 45 connected to the wheel shaft 33 cannot synchronously rotate, so that the rotation between the driving wheel 31 and the moving wheel 45 can be ensured to be in an independent state, namely, in the process that the first motor 32 drives the driving wheel 31 to rotate, the moving wheel 45 cannot rotate along with the driving wheel 31, and the position of the driving wheel 31 is changed, similarly, when the second motor 41 drives the moving wheel 45 to move, the driving wheel 31 cannot rotate along with the moving wheel 45, and interference cannot be caused to the movement of the driving wheel 31 in the length direction of the vehicle body 10.

Alternatively, in one embodiment provided by the present disclosure, the first driving wheel 43, the second driving wheel 44 and the moving wheel 45 may be gears, the transmission belt 42 may be a toothed belt, and the first driving wheel 43, the second driving wheel 44 and the moving wheel 45 are all connected with the transmission belt 42 in a meshing manner. When the second motor 41 drives the first transmission wheel 43 to rotate, the first transmission wheel 43, the second transmission wheel 44 and the moving wheel 45 are all meshed with the transmission belt 42, so that the relative sliding between the transmission belt 42 and the first transmission wheel 43, the second transmission wheel 44 and the moving wheel 45 can be avoided, the transmission between the first transmission wheel 43 and the second transmission wheel 44 can be synchronous, and the transmission precision of the driving wheel 31 can be improved.

In other embodiments provided by the present disclosure, the first transmission wheel 43, the second transmission wheel 44, and the moving wheel 45 may be sprockets, and the transmission belt 42 may be a chain.

For the case that the driving wheel 31 is rotatably sleeved on the wheel shaft 33 and the moving wheel 45 is fixedly sleeved on the wheel shaft 33, the first motor 32 may be a wheel hub motor, and a rotor of the wheel hub motor is connected with the driving wheel 31. The driving wheel 31 is rotatably sleeved on the wheel shaft 33, when the wheel hub motor is started, the rotor of the wheel hub motor rotates and drives the driving wheel 31 connected with the rotor to rotate around the wheel shaft 33, and therefore the rail beam maintenance car 1 is driven. Because the driving wheel 31 is rotatably sleeved on the axle 33, when the driving wheel 31 rotates, the driving wheel 31 does not transmit torque to the moving wheel 45 through the axle 33 to rotate the moving wheel 45, thereby avoiding affecting the transmission belt 42.

In addition, since the first motor 32 is a wheel hub motor, the wheel hub motor can be directly mounted on the driving wheel 31, so that the driving wheel 31 and the wheel hub motor can be driven to synchronously move while the moving wheel 45 moves on the transmission belt 42 along the length direction of the car body 10, and a mounting bracket for allowing the first motor 32 to synchronously move along with the driving wheel 31 does not need to be specially arranged, thereby simplifying the structure of the track beam maintenance car 1.

For the case that the driving wheel 31 is fixedly sleeved on the wheel shaft 33, and the moving wheel 45 is rotatably sleeved on the wheel shaft 33, the first motor 32 may be a rotating motor, the rotating motor is movably mounted on the vehicle body, and an output shaft of the rotating motor is connected to the wheel shaft 33, so that when the rotating motor rotates, the output shaft of the rotating motor drives the wheel shaft 33 to rotate, thereby driving the driving wheel 31 fixedly sleeved on the wheel shaft 33 to synchronously rotate, and realizing driving of the track beam maintenance vehicle 1. In addition, because the moving wheel 45 is rotatably sleeved on the wheel shaft 33, the rotating motor does not drive the moving wheel 45 to rotate synchronously in the process of driving the moving wheel 45 to rotate, that is, in the process of driving the track beam maintenance car 1 to move by the driving wheel 31, the position of the moving wheel 45 does not change, so that the position of the driving wheel 31 in the length direction of the car body 10 is ensured not to change, and the stability of the driving wheel 31 in the process of driving the track beam maintenance car 1 is improved.

In order to further improve the stability and accuracy of the movement of the driving wheel 31 along the length direction of the vehicle body 10 by the movement driving assembly 40, as shown in fig. 4 and 5, optionally, a long groove 11 is formed on the inner side wall of the vehicle body 10, the long groove 11 extends along the length direction of the vehicle body 10, and a part of the in-wheel motor protrudes out of the driving wheel 31 and is movably embedded in the long groove 11. In this way, in the process that the hub motor of the driving wheel 31 of the moving driving assembly 40 moves along the length direction of the car body 10, since part of the hub motor protrudes outward and is movably embedded in the elongated slot 11 with the driving wheel 31, the hub motor slides along the length direction of the elongated slot 11 (and the length direction of the car body 10) under the limiting and guiding effects of the elongated slot 11, and in the process, the elongated slot 11 can guide and limit the movement of the hub motor, so that the situation that the hub motor fluctuates up and down in the sliding process is avoided, and the stability and the safety of the track beam maintenance car 1 in the moving process are improved.

Here, it should be noted that the above-mentioned in-wheel motor may include an electric motor for driving the driving wheel 31 to rotate and a housing for wrapping the outer periphery of the electric motor, wherein the housing is at least partially embedded in the elongated slot 11, so that, since the electric motor is located inside the housing, the housing can protect the electric motor from being damaged during the sliding process of the in-wheel motor relative to the vehicle body 10.

In order to further improve the stability and the smoothness of the sliding of the in-wheel motor in the long groove 11, in an exemplary embodiment provided by the present disclosure, as shown in fig. 5, the shape of the cross section of the inner side wall of the long groove 11 in the width direction of the vehicle body 10 is adapted to the profile of the cross section of the portion of the in-wheel motor embedded in the long groove 11 in the width direction of the vehicle body 10, so that a portion of the in-wheel motor is embedded in the long groove 11 more appropriately, the in-wheel motor slides in the long groove 11 more conveniently, and the in-wheel motor is prevented from bumping and shaking in the height direction during the moving process.

In addition, the above-mentioned vehicle body 10 may include a chassis 13, and side wall plates 12 formed on both sides in the width direction of the chassis 13 and a front wall plate and a rear wall plate respectively formed on both sides in the length direction of the chassis, and a spacing region extending in the length direction may be formed between the chassis 13 and the side wall plates 12, wherein the above-mentioned elongated slot 11 may be formed on a side wall of the side wall plate 12, and the driving wheel 31 may be disposed in the spacing region between the side wall plate 12 and the chassis.

Alternatively, the vehicle body 10 has a cab in which at least two seats 51 are provided spaced apart along the length of the vehicle body 10, the at least two seats 51 being oriented in opposite directions. Thus, when the track beam maintenance vehicle 1 travels forward, the driving wheel 31 and the first motor 32 are located behind the track beam maintenance vehicle 1 (i.e., the driving wheel 31 and the first motor 32 are located on the left side in the drawing direction of fig. 1), and the maintenance person can operate and control the maintenance vehicle through the seat 51 located in front of the track beam maintenance vehicle 1 (i.e., the seat 51 located on the right side in the drawing direction of fig. 1), so that the first motor 32 and the driving wheel 31 are prevented from interfering or interfering with the line of sight of the maintenance person; when the track beam maintenance vehicle 1 runs in the reverse direction, at this time, the moving driving assembly 40 can drive the driving wheel 31 and the first motor 32 to move to the front of the track beam maintenance vehicle 1 (i.e. the driving wheel 31 and the first motor 32 are located on the right side of the drawing direction of fig. 2), and a maintenance person can control the maintenance vehicle through a seat 51 located behind the track beam maintenance vehicle 1 (i.e. the seat 51 located on the left side of the drawing direction of fig. 2), so as to avoid the interference or the interference of the first motor 32 and the driving wheel 31 on the sight of the maintenance person, and influence the normal maintenance operation of the maintenance person on the track beam 100.

As shown in fig. 3, the vehicle body 10 may be composed of a side panel 12, a chassis 13, a dash panel, and a back panel, and the side panel 12, the chassis 13, the dash panel, and the back panel collectively enclose the cab. In addition, a steering wheel 52 and safety belts 53 may be further disposed in the cab, at least two steering wheels 52 are disposed at intervals along the longitudinal direction of the vehicle body 10, the safety belts 53 are disposed in one-to-one correspondence with the seats 51, and a service man can control the steering of the track beam maintenance car 1 by operating the steering wheel 52 during the process that the service man drives the track beam maintenance car 1 to travel on the track beam 100.

As shown in fig. 1 to 2, two sides of the cab in the length direction may be respectively formed with a steering wheel 52, and the installation position of each steering wheel 52 is adapted to the installation position of each seat 51, so that when the rail beam inspection vehicle 1 travels in the forward direction, the driving wheel 31 and the first motor 32 are located behind the rail beam inspection vehicle 1, and an inspector may operate the inspection vehicle through the steering wheel 52 located in front of the rail beam inspection vehicle 1, thereby preventing the first motor 32 and the driving wheel 31 from interfering or interfering with the sight of the inspector; when the track beam maintenance vehicle 1 runs reversely, at this time, the movable driving assembly 40 can drive the driving wheel 31 and the first motor 32 to move to the front of the track beam maintenance vehicle 1, and a maintenance person can control the maintenance vehicle through a steering wheel 52 positioned at the rear of the track beam maintenance vehicle 1, so that the first motor 32 and the driving wheel 31 are prevented from interfering or interfering with the sight of the maintenance person.

Alternatively, the vehicle body 10 is disposed symmetrically about a transverse center line thereof extending in the width direction, and the first road wheel 21 and the second road wheel 22 are disposed symmetrically about the transverse center line of the vehicle body 10. Since the vehicle body 10 is symmetrically disposed about the lateral center line thereof extending in the width direction, and the first road wheels 21 and the second road wheels 22 are symmetrically disposed about the lateral center line of the vehicle body 10, the shape of the vehicle body 10 is uniform regardless of whether the track beam maintenance vehicle 1 is running in the forward direction or in the reverse direction, and it is possible to avoid interference of other structures on the vehicle body 10 with the view of maintenance personnel.

Optionally, as shown in fig. 1 to 2, the track beam maintenance vehicle 1 further includes a first obstacle clearing plate 60 and a second obstacle clearing plate 70, the first obstacle clearing plate 60 and the second obstacle clearing plate 70 both extend in the width direction of the vehicle body 10, the first obstacle clearing plate 60 and the second obstacle clearing plate 70 are respectively located at both ends of the vehicle body 10 in the length direction and are connected to the vehicle body 10, and the first road wheel 21 and the second road wheel 22 are located between the first obstacle clearing plate 60 and the second obstacle clearing plate 70. Specifically, when the track beam maintenance vehicle 1 is running in the forward direction, one of the first obstacle clearing plate 60 and the second obstacle clearing plate 70 connected to the vehicle body 10 can clear an obstacle on the upper surface of the track beam 100 located in front of the track beam maintenance vehicle 1 and prevent the obstacle from interfering with the rotation of the first running wheel 21, the second running wheel 22, and the driving wheel 31, and similarly, when the track beam maintenance vehicle 1 is running in the reverse direction, the other of the first obstacle clearing plate 60 and the second obstacle clearing plate 70 connected to the vehicle body 10 can clear an obstacle on the upper surface of the track beam 100 located in front of the track beam maintenance vehicle 1 and prevent the obstacle from interfering with the rotation of the first running wheel 21, the second running wheel 22, and the driving wheel 31.
