Description

Technical Field

[0001] This disclosure generally relates to the field of vehicle positioning technology, and specifically to a positioning adjustment device for fixing a vehicle to a train flatbed. Background Technology

[0002] During the loading of vehicles onto a train flatbed, to ensure vehicle safety, especially for large vehicles, it is generally required that the vehicles travel along the center line of the flatbed. In existing technology, the movement of vehicles on the flatbed is typically achieved by marking the center line and then manually directing the driver to make adjustments. This method is inefficient, and it is difficult to correct deviations during movement, especially when the vehicle is about to reach its designated position. Reversing the vehicle a sufficient distance on the flatbed before making adjustments is extremely dangerous.

[0003] Therefore, existing technologies need to be improved. Summary of the Invention

[0004] In view of the above-mentioned defects or deficiencies in the prior art, it is desirable to provide a positioning adjustment device for fixing a train flatbed in a vehicle, which can meet the specific needs for positioning adjustment when the train flatbed is in the vehicle state.

[0005] Based on one aspect of the present invention, this application provides a positioning and adjustment device for fixing a train flatbed, the method comprising: First hydraulic device, second hydraulic device, fixed top plate; The first hydraulic device and the second hydraulic device are symmetrically installed at a set distance from the midpoint of the vehicle's tire beam; The upper end of the fixed top plate is provided with a through hole. The fixed top plate is installed on the tire beam of the vehicle through the through hole and moves on the tire beam of the vehicle. The other end of the fixed top plate is fixed to the rear axle steering tie rod of the vehicle and follows or controls the movement of the rear axle steering tie rod of the vehicle. The fixed top plate is fixed at the middle position of the rear axle steering tie rod of the vehicle; The first hydraulic device and the second hydraulic device are aligned with the fixed top plate. The first hydraulic device and the second hydraulic device are located on both sides of the fixed top plate. When the vehicle is traveling straight, the first hydraulic device, the second hydraulic device and the fixed top plate are at the same distance. The first hydraulic device and the second hydraulic device have the same structure; When the first hydraulic device applies a force to the fixed top plate, the fixed top plate moves on the tire beam of the vehicle under the control of the force of the first hydraulic device, and controls the movement of the rear axle steering tie rod of the vehicle, thereby controlling the steering of the vehicle tires.

[0006] In another embodiment, the first hydraulic device includes: a multi-section hydraulic rod, a hydraulic motor, a hydraulic station, and a fixed bracket; The multi-section hydraulic rod is connected to the hydraulic station, and the hydraulic station provides hydraulic energy to drive the multi-section hydraulic rod. The hydraulic station is connected to the hydraulic motor, and the hydraulic motor controls the energy output of the hydraulic station. Under the control of an external power source, the hydraulic motor moves in the forward or reverse direction, thereby controlling the multi-section hydraulic rod to move in the forward or reverse direction. One end of the fixed bracket is connected to the hydraulic station, and the other end is fixed to the tire beam of the vehicle, which is used to stably fix the multi-section hydraulic rod, hydraulic motor and hydraulic station on the tire beam of the vehicle. When the first hydraulic device is working, the multi-section hydraulic rod drives the fixed top plate to move.

[0007] In another embodiment, a first cylinder top block and a second cylinder top block are respectively provided on both sides of the fixed top plate; The first cylinder top block is aligned with the multi-section hydraulic rod of the first hydraulic device, and the second cylinder top block is aligned with the multi-section hydraulic rod of the second hydraulic device.

[0008] In another embodiment, the travel distance of the multi-section hydraulic rod is not less than 30 centimeters.

[0009] In another embodiment, the distance between the first hydraulic device and the midpoint of the vehicle's tire beam is no more than 15 centimeters.

[0010] In this embodiment, a fixed top plate is installed on the rear axle steering tie rod of the vehicle by means of a first hydraulic device and a second hydraulic device on the vehicle's tire crossbeam. The left and right movement of the fixed top plate is controlled by the first and second hydraulic devices, thereby driving the movement of the rear axle steering tie rod and further controlling the steering of the vehicle's tires. This method not only reduces the inaccuracies and dangers caused by manual control, but also makes vehicle positioning more accurate and faster. Attached Figure Description

Detailed Implementation

[0014] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0015] like Figure 1 As shown, the positioning and adjustment device for fixing a train flatbed in this application includes: First hydraulic device 10, second hydraulic device 20, fixed top plate 30; The first hydraulic device 10 and the second hydraulic device 20 are symmetrically installed at a set distance from the midpoint of the vehicle's tire beam 40; The fixed top plate 30 is provided with a through hole at its upper end. The fixed top plate 30 is installed on the tire beam 40 of the vehicle through the through hole and moves on the tire beam 40 of the vehicle. The other end of the fixed top plate 30 is fixed to the rear axle steering tie rod 50 of the vehicle and moves with or controls the rear axle steering tie rod 50 of the vehicle. The fixed top plate 30 is fixed at the middle position of the rear axle steering tie rod 50 of the vehicle. The first hydraulic device 10 and the second hydraulic device 20 are aligned with the fixed top plate 30. The first hydraulic device 10 and the second hydraulic device 20 are located on both sides of the fixed top plate 30. When the vehicle is traveling straight, the first hydraulic device 10 and the second hydraulic device 20 are at the same distance from the fixed top plate 30. The first hydraulic device 10 and the second hydraulic device 20 have the same structure; When the first hydraulic device 10 applies a force to the fixed top plate 30, the fixed top plate 30 moves on the tire beam 40 of the vehicle under the control of the force of the first hydraulic device 10, and controls the movement of the rear axle steering tie rod 50 of the vehicle, thereby controlling the steering of the vehicle tires 60.

[0016] The first hydraulic device 10 and the second hydraulic device 20 are symmetrically installed at a set distance from the midpoint of the vehicle's tire beam 40. The fixed top plate 30 is fixed at the middle position of the rear axle steering tie rod 50 of the vehicle, so that the distance between the first hydraulic device 10, the second hydraulic device 20 and the fixed top plate 30 is the same. This ensures that the adjustment distance of the first hydraulic device 10 and the second hydraulic device 20 to the fixed top plate 30 is the same, thereby making the offset angle of the vehicle tires the same and achieving the purpose of balanced adjustment. Since the rear axle steering tie rod 50 of the vehicle is used to control the steering of the vehicle tires 60, and the fixed top plate 30 is fixed to the rear axle steering tie rod 50, when the first hydraulic device 10 or the second hydraulic device 20 drives the fixed top plate 30 to move, the rear axle steering tie rod 50 of the vehicle is also driven to move synchronously, thus controlling the steering of the vehicle tires 60. This allows the vehicle to adjust its direction of travel while in motion. Since the position adjustment range of the fixed top plate 30 can be large, large-angle adjustments or small-angle fine adjustments to the steering of the vehicle tires 60 can be achieved. This achieves precise control of the vehicle's direction of travel, and enables the vehicle to accurately maintain its center position when traveling on a train flatbed.

[0017] Specifically, the first hydraulic device 10 includes: a multi-section hydraulic rod 11, a hydraulic motor 12, a hydraulic station 13, and a fixed bracket 14; The multi-section hydraulic rod 11 is connected to the hydraulic station 13, and the hydraulic station 13 provides hydraulic energy to drive the multi-section hydraulic rod 11 to work. The hydraulic station 13 is connected to the hydraulic motor 12. The hydraulic motor 12 controls the energy output of the hydraulic station 13. Under the control of an external power source, the hydraulic motor 12 moves in the forward or reverse direction, thereby controlling the multi-section hydraulic rod 11 to move in the forward or reverse direction. One end of the fixed bracket 14 is connected to the hydraulic station 13, and the other end is fixed to the tire beam 40 of the vehicle, which is used to stably fix the multi-section hydraulic rod 11, hydraulic motor 12, and hydraulic station 13 on the tire beam 40 of the vehicle. When the first hydraulic device 10 is working, the multi-section hydraulic rod 11 drives the fixed top plate 30 to move.

[0018] The hydraulic motor 12 operates under the control of an external power source. When the hydraulic motor 12 is working, the hydraulic station 13 is pressurized or depressurized by the direction of rotation of the hydraulic motor 12. In this way, the extension or retraction of the multi-section hydraulic rod 11 can be controlled by the hydraulic station 13. Since the multi-section hydraulic rod 11 drives the fixed top plate 30 to move, the steering of the vehicle tire 60 can be adjusted when the multi-section hydraulic rod 11 extends or retracts.

[0019] Specifically, a first cylinder top block 31 and a second cylinder top block 32 are respectively provided on both sides of the fixed top plate 30; The first cylinder top block 31 is aligned with the multi-section hydraulic rod 11 of the first hydraulic device 10, and the second cylinder top block 32 is aligned with the multi-section hydraulic rod of the second hydraulic device 20.

[0020] The function of the first cylinder top block 31 and the second cylinder top block 32 is to ensure that the force exerted on the fixed top plate 30 by the first hydraulic device 10 and the second hydraulic device 20 can be fully received, thereby increasing the effectiveness of the force.

[0021] The moving distance of the multi-section hydraulic rod 11 is not less than 30 centimeters.

[0022] The distance between the first hydraulic device 10 and the midpoint of the tire beam 40 of the vehicle is no more than 15 centimeters.

[0023] This application utilizes a first hydraulic device and a second hydraulic device on the vehicle's tire crossbeam, and a fixed top plate on the vehicle's rear axle steering tie rod. The first and second hydraulic devices control the left and right movement of the fixed top plate, thereby moving the vehicle's rear axle steering tie rod and further controlling the vehicle's tire steering. This method not only reduces the inaccuracies and dangers of manual control but also makes vehicle positioning more precise and faster.

[0024] The above description is merely a preferred embodiment of this application and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the invention involved in this application is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept. For example, technical solutions formed by substituting the above features with (but not limited to) technical features with similar functions disclosed in this application.
