In the present embodiment, only the slider 1 6 arranged between the upper cross beam 4 and the lower cross beam 5 is shown, and the slider 2 can be arranged according to actual conditions. Specifically, one or two transverse working areas can be formed between the upper cross beam 4 and the lower cross beam 5. In the illustration of the present embodiment, there is only one transverse working area, and two transverse working areas can be arranged according to actual conditions. A lifting platform 7 is arranged in the transverse working area, a base bracket 8 is arranged at the bottom of the first side beam 2 and the second side beam 3, a lifting platform guide rail 9 is arranged on the inner side of the base bracket 8, and a plurality of mutually symmetrical base fixing blocks 10 are arranged on the top of the base bracket 8 for fixing the first side beam 2 and the second side beam 3.

[0024] Example 2, based on the above example, please continue to refer to Figure 1 In the figure, an embodiment structure of the device with only one slider is shown. If there are two sliders, an isolation beam needs to be set between slider 1 6 and slider 2. The isolation beam can be set in the middle of the entire horizontal working area to divide the entire horizontal working area into two horizontal working areas, namely the first horizontal working area and the second horizontal working area, wherein the first horizontal working area is formed between slider 1 6 and the isolation beam, and the second horizontal working area is formed between slider 2 and the isolation beam; in this embodiment, both the first horizontal working area and the second horizontal working area can be horizontally pressed by slider 1 6 and slider 2. In this embodiment, slider 1 6 and slider 2 can be operated synchronously or independently in real time under the control of the electric control and control system, and can also be operated alternately horizontally according to actual conditions. If there are two sliders, there are also two lifting platforms 7, and the lifting platform 7 can further include a lifting platform 1 and a lifting platform 2 of the same size and structure.

[0025] Embodiment 3, on the basis of the above embodiment, if there are two horizontal working areas, it is necessary to set the working table 1 of the first horizontal working area and the working table 2 of the second horizontal working area on the two side surfaces of the isolation beam respectively, and the lifting platform 1 is located in the first horizontal working area; the lifting platform 2 is located in the second horizontal working area; specifically, during work, its large shaft products are placed on the working table, and the bottom is supported by the lifting platform. If there are two horizontal working areas, two products can be placed in the first horizontal working area and the second horizontal working area respectively, and its product 1 is placed at one work table, and the bottom is supported by the lifting platform 1, so that the product 1 is in close contact with the working table 1, and then its product 2 is placed at the second work table, and the bottom is supported by the lifting platform 2, so that the product 2 is in close contact with the working table 2; and then the slider 1 and the slider 2 are used to respectively press and fix the product 1 or / and the product 2 at the working table 1 and the working table 2, which is used to fix the product and the final pressing process of the product, so as to realize the maintenance process of the entire component. After the product is repaired, it is lifted and taken out by the lifting platform 1 and / or the lifting platform 2.

[0026] Example 4, based on the above example, please continue to refer to Figure 2 , which is a detailed structural diagram of the main machine base 1. The main structure of the main machine base 1 is composed of a base bracket 8, a lifting platform guide rail 9, and a base fixing block 10.

When two work surfaces are provided at the same time, the work efficiency can be greatly improved.

[0030] Example 7, continue with the above example, please continue to refer to Figure 1 In the embodiment, a guide plate 17 with the same structure is arranged between both sides where the slider 1 6 is connected to the first side beam 2 and the second side beam 3; a guide plate 2 with the same structure is arranged between both sides where the slider 2 is connected to the first side beam 2 and the second side beam 3. In the embodiment, the guide plate 17 and the guide plate 2 are respectively used for the left and right lateral sliding of the slider 1 6 and / or the slider 2.

[0031] Embodiment 8, based on the above embodiments, a central positioning point is provided on the slider 1 6 and / or the slider 2, and the work surface 1 and / or the work surface 2 to facilitate positioning when placing the product.
