Description

Technical Field

[0001] The invention belongs to the technical field of flatbed car tracks, and in particular relates to a cross track device used for flatbed car operation. Background Art

[0002] Flatbed trucks are widely used in factory workshops. Conventionally, they are used to transport items between different areas of the factory floor, with the truck running perpendicular to the direction of the overhead crane. However, due to limitations in the overhead crane, flatbed trucks are often required to transport items both parallel to and perpendicular to the direction of the overhead crane. This requires the flatbed truck to be able to operate normally at cross-track locations.

[0003] In the existing technology, a disconnect opening is usually set at the cross-intersection of two sets of tracks to enable the flatbed truck to operate normally at the cross-intersection track. However, this treatment method does not take into account the problem of wheel height difference caused by structural deformation under load. In this way, the driving wheel set may not touch the ground, that is, it cannot be driven. In addition, it does not take into account the situation where the center of gravity of the load is offset from the center of the vehicle body. If the center of gravity of the load is not completely in the center of the vehicle body, the flatbed truck will tilt when passing through the track disconnection, resulting in a sinking problem. These problems cause the wheels of the flatbed truck to often sink into the track disconnection when passing through the disconnected track, causing the flatbed truck to be unable to operate. Therefore, the cross-intersection operation of multiple flatbed trucks is difficult to achieve, resulting in the inability to improve the transfer efficiency of the workshop. In summary, there is an urgent need for a cross-intersection track device for the operation of flatbed trucks. Summary of the Invention

[0004] In order to solve some or all of the technical problems existing in the above-mentioned prior art, the present invention provides a cross track device for the operation of a flatbed vehicle.

[0005] The cross track device includes a first track group, a first flatbed vehicle arranged above the first track group, a second track group, and a second flatbed vehicle arranged above the second track group, wherein the first track group and the second track group are arranged perpendicular to each other, wherein:

[0006] The first track group includes a front track group, a middle track group, and a rear track group whose axes coincide with each other, the front track group and the middle track group are separated by a first distance, the middle track group and the rear track group are separated by a second distance, and the front track group and the rear track group are separated by a third distance. A driving wheel group is respectively provided at both ends of the bottom of the first flatbed vehicle, a plurality of driven wheel groups are provided between two driving wheel groups, adjacent driven wheel groups are separated by a fourth distance from the driving wheel group, the driving wheel groups at both ends of the bottom of the first flatbed vehicle are separated by a fifth distance, and the driven wheel groups at both ends of the bottom of the first flatbed vehicle are separated by a seventh distance.

[0007] The second track includes two parallel monorails, one monorail is arranged between the front track group and the middle track group, and the other monorail is arranged between the middle track group and the rear track group. A group of driving wheel groups and a group of driven wheel groups are respectively arranged at both ends of the bottom of the second flatbed vehicle;

[0008] The top of the first track group is higher than the top of the second track group by a sixth distance, the sixth distance is greater than the rim height of the driving wheel group and the rim height of the driven wheel group, the fourth distance is greater than the first distance, the fourth distance is greater than the second distance, and the fifth distance is greater than the third distance.

[0009] Furthermore, in the above-mentioned cross track for the operation of the flatbed vehicle, the driven wheel set is 1 to 3 mm higher than the driving wheel set.

[0010] Furthermore, in the above-mentioned cross track for the operation of the flatbed vehicle, the driving wheel group includes two wheels with overlapping axles, and the driving wheel group is connected to a reducer and a motor.

[0011] As a specific embodiment, in the above-mentioned cross track for the operation of the flatbed truck, the two wheels in the driving wheel group are connected by a coupling and a shaft, and one side of one of the wheels is connected to the reducer and the motor.

[0012] As a specific embodiment, in the above-mentioned cross track for the operation of the flatbed vehicle, the two wheels in the driving wheel set are driven by the reducer and the motor respectively.

[0013] As a specific implementation, in the cross track for the operation of the flatbed vehicle, the number of the driven wheel groups is 2 to 4.

[0014] The cross track device for flatbed vehicle operation of the present invention has the following advantages and positive effects:

[0015] (1) The present invention has a simple structure and is easy to assemble and disassemble. By setting the top of the first track group to be higher than the top of the second track group by a sixth distance, the sixth distance is greater than the height of the rim of the driving wheel group and the height of the rim of the driven wheel group, the fourth distance is greater than the first distance, the fourth distance is greater than the second distance, and the fifth distance is greater than the third distance, it is ensured that when the flatbed car passes through the disconnection of the first track group, at least one wheel of the driving wheel group and the driven wheel group contacts the first track group, and at least one of them is the driving wheel group. In this way, it is ensured that even if the center of gravity of the load deviates from the center of gravity of the flatbed car by a certain distance, the flatbed car will not fall into the disconnection of the first track group, so that the flatbed car always has driving force and can operate normally, thereby solving the problem of how multiple flatbed cars can operate normally at cross tracks;

[0016] (2) The present invention improves the allowable degree of deviation between the load center of gravity and the center of the vehicle body by providing a driving mode of multiple driving wheel groups and driven wheel groups, thereby avoiding the situation where the flatbed truck will tilt and fall when passing through the track disconnection when the load center of gravity is not completely in the center of the vehicle body, thereby preventing the flatbed truck from operating normally. In addition, the driven wheel group is set to be 1 to 3 mm higher than the driving wheel group, thereby avoiding the situation where the driving wheel group does not touch the ground due to the wheel height difference caused by the wheel height difference during the manufacturing process and the structural deformation under load.

[0022] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with specific embodiments of the present invention and corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] like Figure 1 and Figure 2As shown, the present invention provides a cross-track device for flatbed vehicle operation, comprising a first track group 1, a first flatbed vehicle 2 arranged above the first track group 1, a second track group 3, and a second flatbed vehicle 4 arranged above the second track group 3. The first track group 1 and the second track group 3 are arranged perpendicular to each other, wherein the first track group 1 includes a front track group 31, a middle track group 32, and a rear track group 33 whose axes coincide with each other, the front track group 31 and the middle track group 32 are spaced a first distance apart, the middle track group 32 and the rear track group 33 are spaced a second distance apart, and the front track group 31 and the middle track group 32 are spaced a second distance apart. 1 and the rear track group 33 are separated by a third distance. A driving wheel group 5 is respectively provided at both ends of the bottom of the first flatbed car 2. A plurality of driven wheel groups 6 are provided between the two driving wheel groups 5. This arrangement is because the flatbed car deflects downward after being subjected to force, so the driving wheel group 5 needs to be arranged on the outside and the driven wheel group 6 is arranged on the inside. The adjacent driven wheel groups 6 and the driving wheel groups 5 are separated by a fourth distance. The driving wheel groups 5 at both ends of the bottom of the first flatbed car 2 are separated by a fifth distance. The driven wheel groups 6 at both ends of the bottom of the first flatbed car 2 are separated by a seventh distance. The second track group 3 includes two parallel monorails 31, one of which is parallel to each other. The monorail 31 is arranged between the front track group 31 and the middle track group 32, and the other monorail 31 is arranged between the middle track group 32 and the rear track group 33. A group of driving wheel groups 5 and a group of driven wheel groups 6 are respectively arranged at both ends of the bottom of the second flatbed car 4; the top of the first track group 1 is higher than the top of the second track group 3 by a sixth distance, the sixth distance is greater than the height of the rim of the driving wheel group 5 and the height of the rim of the driven wheel group 6, the fourth distance is greater than the first distance, the fourth distance is greater than the second distance, and the fifth distance is greater than the third distance. This arrangement ensures that when the flatbed car passes through the disconnection of the first track group 1, the driving wheel group 5 and the driven wheel group There is at least one wheel in each of 6 in contact with the first track group 1, and at least one of them is the driving wheel group 5, so that it can be ensured that the flatbed car will not fall into the disconnection point of the first track group 1, so that the flatbed car always has driving force and can operate normally. Of course, the first distance, the second distance, and the third distance also need to be set according to the wheel size and spacing of the driving wheel group 5 and the driven wheel group 6 on the second flatbed car 4. It is necessary to ensure that when the second flatbed car 4 runs above the second track group 3 and passes through the disconnection point of the first track group 1, it does not interfere with the first track group 1, and the load center of gravity of the car needs to be limited within the seventh distance.

[0024] Furthermore, in the cross-track device for the operation of the flatbed truck of the present invention, the driven wheel group 6 is 1 to 3 mm higher than the driving wheel group 5. This arrangement is used to ensure that no matter whether the flatbed truck is in an empty or loaded state, one set of the driving wheel groups 5 is always on the ground and can always provide driving force, and the driving force of a single set of driving wheel groups 5 needs to be set to ensure the normal operation of the flatbed truck.

[0025] Furthermore, in the cross-track device for the operation of a flatbed vehicle of the present invention, the driving wheel set 5 includes two wheels with overlapping axles, and the driving wheel set 5 is connected to a reducer 7 and a motor 8.

[0026] As a specific embodiment, in the cross-track device for flatbed vehicle operation of the present invention, the two wheels in the driving wheel group 5 are connected by a coupling and a shaft, and a reducer 7 and a motor 8 are connected to one side of one wheel, and the reducer 7 and the motor 8 can drive the two wheels to rotate synchronously.

[0027] As a specific embodiment, in the cross-track device for flatbed vehicle operation of the present invention, the two wheels in the driving wheel group 5 are driven by the reducer 7 and the motor 8 respectively, and there is no need for a rigid connection between the two wheels. In this way, each wheel has its own separate driving device, ensuring that the flatbed vehicle can operate normally even when the load is high or when passing through the disconnection point of the first track group 1.

[0028] As a specific embodiment, in the cross-track device for flatbed vehicle operation of the present invention, the number of driven wheel groups 6 is 2 to 4 groups. More specifically, the number of driven wheel groups 6 is 2 groups. Of course, the specific number of driven wheel groups 6 will be set according to the specific working conditions such as the flatbed vehicle size and load weight during actual use.

[0029] The working principle of the cross-track device for flatbed operation of the present invention is as follows: the second flatbed 4 drives the driving wheel group 5 to move on the second track group 3 through the reducer 7 and the motor 8. When the first flatbed 2 moves from the front track group 31 to the rear track group 33, the driving wheel group 5 at the frontmost position of the bottom of the first flatbed 2 will first move to the disconnection between the front track group 31 and the middle track group 32. The driving wheel group 5 is in a suspended state during the process of passing through the disconnection, and the first flatbed 2 continues to move. Since the sixth distance is greater than the rim height of the driving wheel group 5 and the rim height of the driven wheel group 6, the driving wheel group 5 can pass through the disconnection smoothly. After passing through the disconnection, the driving wheel group 5 abuts against the middle track group 3. 2, so the driven wheel group 6 adjacent to the driving wheel group 5 is also in a suspended state when passing through the disconnection between the front track group 31 and the middle track group 32. As the first flatbed truck 2 continues to move, the driving wheel group 5 at the frontmost position of the bottom of the first flatbed truck 2 will be displaced to the disconnection between the middle track group 32 and the rear track group 33. Similarly, the driving wheel group 5 is in a suspended state when passing through the disconnection. The first flatbed truck 2 continues to move. Since the sixth distance is greater than the rim height of the driving wheel group 5 and the rim height of the driven wheel group 6, the driving wheel group 5 can pass through the disconnection smoothly. The other wheel groups are all displaced from the front track group 31 to the rear track group 33 and from the rear track group 33 to the front track group 31 through a principle similar to the above.

[0030] In summary, compared with the prior art, the cross track device for flatbed vehicle operation of the present invention has the following advantages and positive effects:

[0031] (1) The present invention has a simple structure and is easy to assemble and disassemble. By setting the top of the first track group 1 to be higher than the top of the second track group 3 by the sixth distance, the sixth distance is greater than the height of the rim of the driving wheel group 5 and the height of the rim of the driven wheel group 6, so that the fourth distance is greater than the first distance, the fourth distance is greater than the second distance, and the fifth distance is greater than the third distance, the load center of gravity of the trolley needs to be limited within the seventh distance to ensure that when the flatbed car passes through the disconnection of the first track group 1, at least one wheel of the driving wheel group 5 and the driven wheel group 6 is in contact with the first track group 1, and at least one of them is the driving wheel group 5. In this way, it can be ensured that even if the load center of gravity deviates from the center of gravity of the flatbed car by a certain distance, the flatbed car will not fall into the disconnection of the first track group 1, so that the flatbed car always has driving force and can operate normally, thereby solving the problem of how multiple flatbed cars can operate normally at cross tracks;

[0032] (2) The present invention improves the allowable degree of deviation between the load center of gravity and the center of the vehicle body by providing a variety of driving modes of driving wheel groups 5 and driven wheel groups 6, thereby avoiding the situation where the flatbed truck will tilt and fall when passing through the track disconnection when the load center of gravity is not completely in the center of the vehicle body, thereby preventing the flatbed truck from operating normally. In addition, the driven wheel group 6 is set to be 1 to 3 mm higher than the driving wheel group 5, thereby avoiding the situation where the driving wheel group 5 does not touch the ground due to the wheel height difference caused by the wheel height difference during the manufacturing process and the structural deformation under load.
