Technical Field
[0001] This application relates to the technical field of vehicle maintenance, and particularly to a maintenance platform for vehicle engineering. Background Art
[0002] In the prior art, the chassis area of a vehicle is usually routinely inspected or repaired through a maintenance platform. Two maintenance platforms are used in cooperation, and the space between the two maintenance platforms can be used for maintenance personnel to perform maintenance operations on the vehicle. During maintenance, it is usually necessary to drive the vehicle onto the maintenance platform to increase the distance between the chassis of the vehicle and the ground, leaving enough space for the maintenance personnel to perform maintenance. And in some special cases, for example, when only the chassis near the front wheels of the vehicle needs to be maintained, at this time, only the front wheels of the vehicle can be located on the maintenance platform, and the rear wheels of the vehicle are still on the ground. At this time, the chassis of the vehicle is in an inclined state to facilitate the maintenance personnel to perform maintenance. However, the maintenance platforms in the prior art usually cannot limit the wheels, and the vehicle is prone to roll back during the maintenance process. Summary of the Utility Model

[0014] Advantages that can be achieved by the present application:
[0015] A maintenance platform for vehicle engineering proposed in the embodiment of the present application, by providing a limiting member and a driving member on the maintenance platform. When the wheel moves onto the driving member, relying on the downward pressure exerted by the wheel on the driving member, the driving member moves downward and applies an upward thrust to the limiting member through the lever, so that the height of the convex platform body of the limiting member increases. By using the limiting member to block the movement of the wheel, the situation of the vehicle slipping backward can be prevented. When the wheel of the vehicle moves from the left side to the right side of the limiting member and moves onto the driving member, the limiting member automatically moves upward to achieve the limiting effect on the wheel, without manual operation, realizing automatic anti-backsliding of the vehicle.

[0027] Embodiment 1
[0028] Refer to Figures 1-4 , Figure 1 in which X is the first direction and Y is the second direction. The first embodiment of the present application provides an overhaul platform for vehicle engineering, including: a platform body 10 and a limiting component. The platform body 10 is used to carry the wheels 60 of the vehicle; at least one limiting component is arranged on the platform body 10; wherein, the limiting component includes a limiting member 30, a driving member 20 and a lever 40. The limiting member 30 and the driving member 20 are arranged along the first direction on the platform body 10. A supporting member 50 is arranged at the lower end of the platform body 10. The lever 40 is rotatably arranged on the supporting member 50 through a pin shaft 41; the limiting member 30 and the driving member 20 penetrate through the platform body 10 along the second direction. The lower ends of the limiting member 30 and the driving member 20 are respectively in contact with both ends of the lever 40 on both sides of the pin shaft 41. When the wheel 60 drives the driving member 20 to move downward along the second direction, the limiting member 30 is driven to move upward along the second direction through the lever 40, so that the limiting member 30 and the wheel 60 form a limiting structure to prevent the wheel 60 from moving.
[0029] In this embodiment, during the use of the platform body 10, usually two platform bodies 10 are used side by side. The two platform bodies 10 are respectively used to carry the wheels 60 on both sides of the vehicle, that is, the front, rear and rear wheels on one side of the vehicle can move onto the same platform body 10. When the wheels 60 of the vehicle are driven onto the platform body 10, the wheels 60 start from the side of the limiting member 30 away from the driving member 20 and move towards the direction close to the driving member 20. In the initial state, the wheels 60 can move to the upper end of the limiting member 30, driving the limiting member 30 to move downward. At this time, the driving member 20 is driven to move upward through the lever 40 (the schematic diagram of its state is as Figure 3As shown in the figure, when the wheel 60 crosses the limiting member 30, the wheel 60 contacts the upper end of the driving member 20. The wheel 60 applies a downward pressure on the driving member 20, causing the driving member 20 to move downward. During the downward movement of the driving member 20, an upward thrust is applied to the limiting member 30 through the lever 40, causing the upper end of the limiting member 30 to move upward and protrude from the upper end surface of the platform body 10 (the schematic diagram of its state is as shown in Figure 1 ). Since the wheel 60 continuously applies a downward pressure on the driving member 20, that is, maintaining the current state of the driving member 20 unchanged. At this time, a thrust is applied to the limiting member 30 through the lever 40. The lever 40 abuts against the limiting member 30 and restricts the downward movement of the limiting member 30, realizing the limiting function of the limiting member 30 on the wheel 60 and preventing the wheel 60 from slipping backward. When the maintenance is completed, or when the wheel 60 of the vehicle also needs to move onto the platform body 10, the wheel 60 continues to move forward. After the front wheel 60 located at the front end disengages from the driving member 20, the limiting member 30 moves downward to reset, so that the rear wheel 60 can repeat the movement of the front wheel above. That is, the backward movement of the wheel 60 is restricted by the limiting rod, and the forward movement of the wheel 60 is not restricted.
[0030] Embodiment 2
[0031] As an alternative embodiment, referring to Figure 1 , this embodiment provides a positional relationship between the limiting member 30 and the driving member 20, including: the axes of the limiting member 30 and the driving member 20 are parallel to each other.
[0032] Optionally, the first direction and the second direction are perpendicular to each other.
[0033] In this embodiment, by making the axes of the limiting member 30 and the driving member 20 parallel to each other, the stability of force transmission through the lever 40 is improved.
[0034] Embodiment 3
[0035] As an alternative embodiment, referring to Figure 1 and Figure 3 , this embodiment provides an adjustment structure of the driving member 20, including: a first through groove 21 extending in the first direction is provided on the platform body 10. The driving member 20 penetrates through the first through groove 21 and can move along its extending direction. An adjustment assembly 23 is provided on the support member 50. The adjustment assembly 23 is used to adjust the position of the driving member 20 in the first direction within the first through groove 21.
[0036] Optionally, the adjusting assembly 23 includes a mounting block 231, an adjusting rod 232, and an adjusting nut 233. Both ends of the adjusting rod 232 are disposed on the support member 50 through the mounting block 231. The driving member 20 has a second through groove 22 that penetrates in the first direction and extends in the second direction. The adjusting rod 232 passes through the second through groove 22. Two adjusting nuts 233 are sleeved on the adjusting rod 232 and are respectively located on both sides of the driving member 20. The adjusting nut 233 is in threaded engagement with the adjusting rod 232.
[0037] In this embodiment, by providing a first through groove 21 extending in the first direction on the platform body 10, the relative position of the driving member 20 in the first direction can be adjusted, that is, the distance between the driving member 20 and the limiting member 30 can be adjusted, so as to be adjusted according to different sizes and models of the wheels 60. When the wheel 60 presses the driving member 20, the limiting member 30 can be in contact with the wheel 60. When the wheel 60 presses the driving member 20, the distance between the limiting member 30 and the wheel 60 is too large, resulting in the wheel 60 moving backward a certain distance, the driving member 20 moving upward, and the limiting member 30 moving downward, resulting in the limiting member 30 losing its limiting effect on the wheel 60. By providing an adjusting assembly 23 on the support member 50, the relative position of the driving member 20 is fixed by adjusting the relative positions of the adjusting nuts 233 on the left and right sides of the driving member 20 on the adjusting rod 232, preventing the driving member 20 from moving left and right randomly. The adjusting nuts 233 on the left and right sides only limit the left and right movement of the driving member 20, but do not limit the up and down movement of the driving member 20.
[0038] Embodiment 4
[0039] As an alternative embodiment, referring to Figure 1 and Figure 3 , this embodiment provides a specific structure of the limiting member 30, including: a third through groove 34 that penetrates in the first direction and extends in the second direction is provided at the lower end of the limiting member 30. One end of the lever 40 passes through the third through groove 34. A moving block 33 is threadedly connected to the outer wall of the limiting member 30. The moving block 33 can move along the extension direction of the third through groove 34 so that the moving block 33 can be in contact with the lever 40 to form a limiting structure.
[0040] Optionally, a contact portion 331 is provided at one end of the moving block 33 close to the lever 40, and the outer wall of the contact portion 331 is an arc surface.
[0041] In this embodiment, by threadedly connecting the moving block 33 to the limiting member 30, the moving block 33 can move up and down on the limiting member 30. When the lever 40 drives the limiting member 30 to move up and down, it is the moving block 33 that contacts the lever 40. By adjusting the relative position of the moving block 33 in height. With different heights of the moving block 33, when the driving member 20 moves downward by the same distance, the upward moving distance of the limiting member 30 is different, enabling adaptation to wheels 60 of different size specifications and improving its scope of application. By providing a contact portion 331 with an arc surface on the moving block 33, when the lever 40 contacts the moving block 33 at different relative height positions, the contact stability is improved.
[0042] Embodiment 5
[0043] As an alternative implementation, referring to Figure 1 and Figure 3 , this embodiment provides a specific structure of the limiting member 30, including: a baffle 32 is provided on the outer wall of the limiting member 30, and a compression spring 31 is sleeved on the limiting member 30. The compression spring 31 is located between the baffle 32 and the lower end of the platform body 10.
[0044] In this embodiment, by providing the compression spring 31, a downward thrust is applied to the limiting member 30, so that the limiting member 30 always has a tendency to move downward. When the wheel 60 disengages from the driving member 20, the limiting member 30 can automatically move downward under the action of the return spring to restore its initial state, enabling the next wheel 60 to smoothly move past the limiting member 30 to the position of the driving member 20, and reducing the situation where the limiting member 30 hinders the normal movement of the next wheel 60.
[0045] Embodiment 6
[0046] As an alternative implementation, referring to Figure 1 and Figure 3 , this embodiment provides a specific structure of the lever 40, including: the distance between the pin shaft 41 and the driving member 20 along the first direction is less than the distance between the pin shaft 41 and the limiting member 30 along the first direction.
[0047] In this embodiment, by limiting the position of the pin shaft 41, that is, respectively limiting the lengths of the force arms of the driving member 20 and the limiting member 30 that contact the lever 40, the moving distance of the limiting member 30 is greater than the moving distance of the driving member 20, so as to ensure that after the wheel 60 moves from left to right over the limiting member 30, the wheel 60 can control the driving member 20 to move downward.
[0048] Embodiment 7
[0049] As an alternative implementation, referring to Figures 1-4, this embodiment provides a specific structure of the platform body 10, including: guiding members 11 are respectively arranged at both ends of the platform body 10 along the first direction, and the guiding members 11 have inclined guiding surfaces.
[0050] In this embodiment, by arranging the guiding members 11, the vehicle is guided, enabling the vehicle to smoothly move onto the platform body 10 and also smoothly move off the platform body 10.
[0051] The above are only the preferred embodiments of the present application, and do not limit the patent scope of the present application accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present application, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present application.
