[0039] like Figures 1-4 As shown, an embodiment of the present invention provides a pit structure for a shallow pit car lift, comprising a pit 1 extending along a first horizontal direction and a cover plate 2 disposed on the side wall of the pit 1. The cover plate 2 is used to seal the pit opening of the pit 1 and is provided with a clearance opening 23. The cover plate 2 is movably connected to the side wall of the pit 1 so that the cover plate 2 can be opened or closed. A shallow pit car lift 100 is movably disposed within the pit 1. When the cover plate 2 is open, the shallow pit car lift 100 can move within the pit 1 along the first horizontal direction to a position corresponding to the clearance opening 23 of the cover plate 2, thereby facilitating adaptive adjustment of the shallow pit car lift 100 according to the position of the vehicle body 200. When the cover plate 2 is closed, the shallow pit car lift 100 passes through the clearance opening 23 so that the clearance opening 23 can clear the shallow pit car lift 100, thereby preventing interference between the shallow pit car lift 100 and the cover plate 2.

[0040] The foundation pit structure of the shallow pit type car lifting machine enables the shallow pit type car lifting machine 100 to be set in the foundation pit 1, and when the cover plate 2 is in the open state, the shallow pit type car lifting machine 100 can adjust its position. When the cover plate 2 is in the closed state, the cover plate 2 can seal the pit mouth of the foundation pit 1, so that maintenance personnel can stand on the cover plate 2 to perform maintenance operations without being affected by the base 1011 of the shallow pit type car lifting machine 100, thereby improving maintenance efficiency.

[0041] Optionally, the cover plate 2 includes a first cover plate 21 and a second cover plate 22 that are distributed in opposite directions along the second direction, and the opposite ends of the first cover plate 21 and the second cover plate 22 are respectively hinged to the opposite side walls of the foundation pit 1 along the second horizontal direction, so that the first cover plate 21 and the second cover plate 22 can be rotated open and rotated closed respectively; the facing ends of the first cover plate 21 and the second cover plate 22 are respectively provided with a first opening groove and a second opening groove. When the cover plate 2 is in a closed state, the first opening groove and the second opening groove constitute an avoidance opening 23. This structure allows the first cover plate 21 and the second cover plate 22 to not interfere with the shallow pit vehicle lifting machine 100 when opening or closing, and the operation is more convenient.

[0042] The first horizontal direction and the second horizontal direction are perpendicular to each other.

[0043] To ensure the load-bearing capacity of the first cover plate 21 and the second cover plate 22, the pit structure of the shallow pit vehicle lift also includes a first bracket 3 and a second bracket 4 spaced apart along the second horizontal direction. The first bracket 3 and the second bracket 4 are respectively connected perpendicularly to the side walls of the pit 1 that are opposite to each other along the second horizontal direction. When the cover plate 2 is in the closed state, the first cover plate 21 and the second cover plate 22 are supported by the first bracket 3 and the second bracket 4, respectively. This structure ensures that when maintenance personnel stand on the first cover plate 21 or the second cover plate 22, the first bracket 3 and the second bracket 4 provide support for the first cover plate 21 and the second cover plate 22, respectively, preventing the first cover plate 21 and the second cover plate 22 from collapsing and causing safety accidents.

[0044] Specifically, the first bracket 3 includes a first cross frame 31 and a first diagonal rod 32. The first cross frame 31 is connected to the side wall of the foundation pit 1. One end of the first diagonal rod 32 is connected to the side wall of the foundation pit 1, and the other end is connected to the side of the first cross frame 31 away from the first cover plate 21. When the first cover plate 21 is in the closed state, the first cover plate 21 is supported on the first cross frame 31. In this structure, the first cross frame 31 is supported on the first cover plate 21 to provide stable support for the first cover plate 21, and the first diagonal rod 32 further improves the bearing capacity of the first cross frame 31.

[0045] The second bracket 4 includes a second cross frame 41 and a second diagonal rod 42. The second cross frame 41 is connected to the side wall of the foundation pit 1. One end of the second diagonal rod 42 is connected to the side wall of the foundation pit 1, and the other end is connected to the side of the second cross frame 41 away from the second cover plate 22. When the second cover plate 22 is in the closed state, the second cover plate 22 is supported on the second cross frame 41. In this structure, the second cross frame 41 is supported on the second cover plate 22 to provide stable support for the second cover plate 22. The second diagonal rod 42 further improves the bearing capacity of the second cross frame 41.

[0046] In order to facilitate the opening and closing of the first cover plate 21 and the second cover plate 22, the foundation pit structure of the shallow pit car lifting machine also includes a first driving member 5 and a second driving member 6 spaced apart along the second horizontal direction. The fixed end of the first driving member 5 is hinged to the side wall of the foundation pit 1, and the output end of the first driving member 5 is hinged to the first cover plate 21. The output end of the first driving member 5 is used to drive the first cover plate 21 to open when extended, and the output end of the first driving member 5 is used to drive the first cover plate 21 to close when retracted; the fixed end of the second driving member 6 is hinged to the side wall of the foundation pit 1, and the output end of the second driving member 6 is hinged to the second cover plate 22. The output end of the second driving member 6 is used to drive the second cover plate 22 to open when extended, and the output end of the second driving member 6 is used to drive the second cover plate 22 to close when retracted.

[0047] Optionally, the first driving member 5 and the second driving member 6 can be selected as electric push rods, air cylinders or oil cylinders.

[0048] In this embodiment, the first cover plate 21 is arranged on the side close to the vehicle body 200 along the second horizontal direction, and the second cover plate 22 is arranged on the side away from the vehicle body 200 along the second horizontal direction. Since maintenance personnel stand on the second cover plate 22 frequently, it is necessary to increase the load-bearing capacity of the second cover plate 22. By setting the width dimension of the second cover plate 22 along the second horizontal direction to be smaller than the width dimension of the first cover plate 21 along the second horizontal direction, the load-bearing capacity of the second cover plate 22 can be improved.

[0049] Optionally, in order to facilitate the movement of the shallow pit type vehicle lifting machine 100 in the foundation pit 1, a track extending along the first horizontal direction is provided at the bottom of the foundation pit 1, and the shallow pit type vehicle lifting machine 100 is movably provided on the track.

[0050] In order to prevent water accumulation in the foundation pit 1, a drainage pipe is provided in the foundation pit 1. The drainage pipe is connected to the drainage system.
