As shown in fig. 1, the present embodiment provides a pit type car lifting mechanism for supporting a car to be overhauled. When the locomotive is not overhauled, the pit type car lifting mechanism of the car lifting machine is positioned in the pit. When the locomotive is overhauled, the lifting mechanism of the pit type vehicle lifting machine body rises to push the ground movable cover plate 100 to open and extend out of the ground.
Specifically, the pit type car lifting mechanism comprises a lifting upright post 1 and a lifting head 2. The lifting supporting head 2 is arranged at the upper end of the lifting upright post 1. The lifting upright post 1 can be lifted, so as to drive the lifting supporting head 2 to extend out or fall into the pit. After the lifting supporting head 2 extends out of the ground, the maintenance locomotive is supported. The lifting support head 2 can rotate relative to the lifting upright post 1. When the lifting support head 2 penetrates through the ground movable cover plate 100, the lifting support head 2 rotates to a vertical state, the size of the whole structure in the horizontal direction is reduced, and the setting size of the movable cover plate 100 is further reduced. The smaller the size of the removable cover plate 100 is, the smaller the requirements on the structural strength and rigidity of the removable cover plate 100 are, the more easily the requirement on the strength of the ground forklift when the forklift passes through the full load is met, and the higher the reliability of the removable cover plate 100 is. After the movable cover plate 100 is stretched out, the lifting supporting head 2 rotates to a horizontal position to support the maintenance locomotive, and meanwhile, the lifting upright post 1 supports the lifting supporting head 2.
In the embodiment, the lifting support head 2 is rotatable relative to the lifting upright post 1, and the lifting support head 2 is in a vertical position when passing through the movable cover plate 100, so that the passing space in the horizontal direction of the whole structure is reduced, the setting size of the movable cover plate 100 is reduced, the requirements on the strength and rigidity of the movable cover plate 100 are reduced, and the reliability of the movable cover plate 100 is improved. The movable cover plate 100 is changed from the existing split type to the single-split type, and the whole size can be reduced by about half.
Preferably, when the lifting support head 2 rotates to the vertical state, the lifting support head 2 is attached to the side surface of the lifting upright post 1, so that the size of the whole structure in the horizontal direction is reduced as much as possible. The upper end face of the lifting upright post 1 is provided with a support piece 3, and when the lifting support head 2 rotates to a horizontal position, the lifting support head 2 presses against the support piece 3. The lifting upright post 1 stably supports the lifting support head 2 through a support piece 3. Alternatively, the support 3 may be a support plate or a rubber pad. The upper end part of the lifting upright post 1 is provided with an avoiding inclined plane 11, so that the lifting support head 2 can rotate relative to the lifting upright post 1 conveniently.
The lifting mechanism of the pit type car lifting machine body further comprises a first driving component (not shown in the figure) for driving the lifting supporting head 2 to rotate. The first drive assembly is preferably an electric motor. The lifting supporting head 2 is rotatably connected with the lifting upright post 1 through a pin shaft, and the first driving component drives the lifting supporting head 2 to rotate relative to the lifting upright post 1.
Further, the lifting mechanism of the car body of the pit type car lifting jack also comprises a second driving assembly 4 and a transmission assembly 5. The second driving assembly 4 drives the lifting upright post 1 to lift through the transmission assembly 5. The second drive assembly 4 is preferably an electric motor. The second drive assembly 4 is fixed in the pit by a fixing plate 7. The transmission assembly 5 comprises a screw 51 and a nut 52 cooperating with each other. The output end of the second driving assembly 4 is connected with the lead screw 51 to drive the lead screw 51 to rotate. The screw 51 further drives the lifting upright 1 to ascend or descend through the nut 52.
The lifting mechanism of the pit type car lifting machine body further comprises a guide device 6 for guiding the lifting motion of the lifting upright post 1. In this embodiment, the guiding device 6 includes a plurality of guiding rollers 61, the guiding rollers 61 are disposed on two sides of the lifting upright 1, and the guiding rollers 61 are in rolling friction with the lifting upright 1. In this embodiment, two guide rollers 61 are provided, and the two guide rollers 61 are respectively disposed on two sides of the lifting upright 1. Obviously, the number and the arrangement mode of the guide rollers 61 can be adjusted according to specific conditions, as long as reasonable bearing requirements can be met, and the structural stability of the lifting column in the maximum lift range is ensured.
The guiding device 6 further comprises a guiding support 62, and the guiding roller 61 is arranged on the guiding support 62. The guide support seat 62 is provided with a notch 63 for avoiding the rotation of the lifting support head 2.
In the pit type car lifting machine automobile body lifting mechanism that this embodiment provided, it is rotatable for lifting upright 1 to lift by setting up to lift supporting head 2, and lift supporting head 2 when passing removable cover 100, be in vertical position, thereby reduce the space of passing through on the horizontal direction of whole structure, and then reduce removable cover 100's set up size, removable cover 100's size is less, the less to its self structural strength and rigidity's requirement, easily satisfy the intensity demand when ground fork truck is fully loaded with the passing through more, removable cover 100's reliability is higher. The movable cover plate 100 is changed from the existing split type to the single-split type, and the whole size can be reduced by about half.
It should be noted that fig. 1 only shows a half structure of the car body lifting mechanism of the pit car lifting jack, that is, the car body lifting mechanism of the pit car lifting jack includes two structures which are symmetrically arranged along the vertical direction and are shown in the figure.
It should be noted that the foregoing is only a preferred embodiment of the present invention and the technical principles applied. It will be understood by those skilled in the art that the present invention is not limited to the particular embodiments described herein, but is capable of various obvious changes, rearrangements and substitutions as will now become apparent to those skilled in the art without departing from the scope of the invention.
