[0032] The support platform 1 comprises a support plate 11, and a plurality of convex teeth are evenly arranged on both sides of the support plate 11; one end of the support platform 1 is welded to the side plate 12, and the side plate 12 and the support platform 1 are arranged in an L shape;

[0033] The lifting mechanism 2 includes an outer frame 21, and the side of the side plate 12 away from the support plate 11 is fixedly connected to the outer frame 21; two connecting frames 22 are symmetrically welded to the side of the outer frame 21 away from the side plate 12, and both ends of the two connecting frames 22 are rotatably connected to guide wheels 23, and multiple guide wheels 23 are respectively located on the side of the connecting frames 22 away from each other; the inner lower ends of the two connecting frames 22 are welded with connecting plates 24, and the ends of the two connecting plates 24 away from the connecting frames 22 are welded to the outer frame 21;

The staff can directly contact the car through the space between the two base frames 4 and the through grooves of the support plate 11, so that the staff can normally install the car. At the same time, the support plate 11 can also increase the contact area with the car by using multiple protruding teeth, thereby ensuring that the support plate 11 can support the car without affecting the normal installation of the car, thereby ensuring the stability of the car in the wellhead.

[0042] The working principle of the utility model is as follows: the initial position of the support platform 1 is located at the base frame 4, and the car is first placed on the support platform 1.

The staff can directly contact the car through the space between the two base frames 4 and the through grooves of the support plate 11, so that the staff can normally install the car. At the same time, the support plate 11 can also increase the contact area with the car by using multiple protruding teeth, thereby ensuring that the support plate 11 can support the car without affecting the normal installation of the car, and ensuring the stability of the car in the wellhead;

[0044] During the installation of the car, according to the progress of the car installation work, it is necessary to change the position of the car in the wellhead. At this time, the staff uses the handrail 72 to press down the connecting rod 71, so that the hydraulic cylinder 81 can operate, and the telescopic rod of the hydraulic cylinder 81 can push the horizontal axis 85. The working principle is the same as the working principle of the manual hydraulic cylinder and the jack, which will not be repeated here; while the horizontal axis 85 moves upward, it drives the two lifting wheels 86 to rise synchronously, and the two lifting wheels 86 drive the two traction ropes 84 close to the end of the connecting plate 24 to rise, thereby driving the outer frame 21 to rise; when the outer frame 21 rises, the multiple guide wheels 23 roll and rise in the two vertical frames 31 respectively, and the two vertical frames 31 play the role of supporting the outer frame 21.
