[0002] The main function of the switchgear is to open and close, control and protect electrical equipment during the power generation, transmission, distribution and energy conversion process of the power system. Before the switchgear is put into use, it is necessary to install the outer shell of the switchgear at the designated location, and then assemble the switchgear components inside the shell before finally putting it into use; before installing the switchgear shell, it is necessary to level the location where the switchgear is installed to avoid the switchgear being unstable after installation and thus affecting its use.

[0003] At present, when installing the switch cabinet casing, the installers usually measure the ground manually at the designated installation site, and then manually level the ground after the switch cabinet is placed. Since the location where the switch cabinet is installed is relatively small, the installation site may only be large enough to place the switch cabinet, which makes it inconvenient to level the cabinet feet of the switch cabinet, and there are certain limitations. At the same time, during the leveling process, the leveling accuracy is only viewed with the naked eye through a spirit level, and there is a certain error in the leveling accuracy.

[0004] The existing leveling work before assembly of switch cabinets is rather troublesome. The limited installation site does not support leveling after the switch cabinet is placed. There is a certain error in measuring the leveling in advance, which makes the subsequent use of the switch cabinet unstable. Therefore, the present invention proposes a switch cabinet manufacturing and assembly preprocessing device. Summary of the invention

[0027] The present invention has the following beneficial effects:

[0028] 1. The present invention provides a sliding component and two sets of racks, one above and one below. When the switch cabinet needs to be assembled, the leveling component surrounded by the lower rack is moved to the top of the designated switch cabinet installation location, and the ground flatness is leveled at four corner points of the designated installation location by using the leveling component. The four corner points are four pressure data points. According to the spring deformation of the four pressure data points, the upward pushing distance of the four electric push blocks is adjusted to level the leveling component. After the leveling is completed, the switch cabinet body installed on the leveling component surrounded by the upper rack is driven by the driving shaft to drive the gear to rotate, thereby driving the leveling component to gradually translate to the top of the designated installation location, and the four lifting columns are aligned with the four pressure data points. The pre-leveled switch cabinet body and the leveling component installed at the bottom are placed at the designated installation location together by the electric lifting rod and the electric suction cup. This can improve the efficiency of installation and is suitable for the assembly of switch cabinets in more spaces, avoiding the assembly of the switch cabinet being hindered due to the small assembly space.

[0029] 2. The present invention sets a leveling component, installs the contact block directly below the slider, and drives the slider to slide on the surface of the screw rod by rotating the screw rod, thereby driving the contact block below to slide on the contacted ground. Since the mounting frame is first leveled, when the installation ground is uneven, the spring undergoes different deformation amounts after the contact block contacts the ground, thereby generating different pressures on the pressure sensor. The deformation amounts of the spring at the four pressure data points are obtained based on the pressure data of the four pressure data points. The larger the deformation amount, the higher the ground protrusion, so the corresponding electric push block pushes upward a higher distance; the smaller the deformation amount, the smaller the ground protrusion, so the corresponding electric push block pushes upward a smaller distance; thereby achieving the leveling effect. This method can accurately measure the flatness of the ground at the installation location, thereby accurately performing leveling.

[0030] 3. The present invention sets a leveling component to adjust the lifting height of the corresponding four lifting columns according to the spring deformation of four pressure data points measured in advance. The higher the ground protrusion is, the higher the lifting height of the lifting column needs to be, so as to ensure balance. During the leveling process, adjacent leveling blocks become closer and closer as the height of their respective lifting columns increases. After the leveling is completed, the locking rod passes through the through hole on the clamping groove to lock the leveling block, thereby preventing the leveling block from being displaced and achieving locking after leveling.
