[0002] A high-voltage switch cabinet is a common electrical equipment. Electrical components are usually installed in the high-voltage switch cabinet. The assembled high-voltage switch cabinet is heavy, and it is time-consuming and laborious to carry it manually.

[0003] The existing Chinese utility model patent "A transfer cart for a high-voltage switch cabinet circuit breaker", with the patent application number CN201820310668.X, provides a transfer cart. This transfer cart transports the circuit breaker of the high-voltage switch cabinet through a transfer platform, a walking component and a lifting component. However, if it is used to transport a high-voltage switch cabinet with a heavier mass and a larger volume, it will be difficult to carry the high-voltage switch cabinet onto the transfer platform and move it off the transfer platform.

[0004] Therefore, it is necessary to provide a transfer cart for a high-voltage switch cabinet to solve the above technical problems. Summary of the Utility Model

[0005] The purpose of the utility model is to overcome the deficiencies of the existing technology and provide a transfer cart for a high-voltage switch cabinet.

The lower end of the first connecting rod is fixedly hinged to the lower track seat, the upper end of the first connecting rod is slidably hinged to the upper track seat, the lower end of the second connecting rod is slidably hinged to the lower track seat, and the upper end of the second connecting rod is fixedly hinged to the upper track seat. The top bracket is provided with an upper cross beam, and the bottom bracket is provided with a lower cross beam. One end of an electric lifting rod is fixedly connected to the upper cross beam, and the other end is fixedly connected to the lower cross beam. A support platform is arranged above the top bracket, and a transfer platform is arranged above the support platform. A height fine-tuning device is arranged between the support platform and the transfer platform. The top surface of the support platform is provided with multiple rows of coaxially arranged rollers. The adjacent two rollers in the same row are equidistantly arranged, and the rollers in the same column are aligned front and back along a straight line. Multiple strip-shaped grooves are formed on the transfer platform, and each strip-shaped groove corresponds to a column of rollers.

[0008] Preferably, the width of the strip-shaped groove is greater than the width of the roller, and the length of the strip-shaped groove is greater than the total length of a column of rollers.

[0009] Preferably, the height fine-tuning device is arranged at the four corners of the support platform and the transfer platform. The height fine-tuning device includes a threaded rod fixedly connected to the bottom surface of the transfer platform. The threaded rod is arranged vertically. A connection hole corresponding to the threaded rod is provided on the top surface of the support platform. The threaded rod is inserted into the connection hole.

[0010] Preferably, baffles are arranged on both sides of the transfer platform.

[0011] Preferably, universal wheels are installed at the four corners of the bottom of the bottom bracket.

[0012] Compared with the prior art, the present utility model has the following advantages:

[0013] By installing a height fine-tuning device between the support platform and the transfer platform to adjust the distance between the support platform and the transfer platform. When it is necessary to move the high-voltage switchgear onto the transfer platform, lower the height of the transfer platform so that the top of the roller of the support platform extends out of the transfer platform along the strip groove, changing the sliding friction between the top surface of the original transfer platform and the bottom surface of the high-voltage switchgear into rolling friction. After moving it onto the transfer platform, adjust the height fine-tuning device again to raise the transfer platform so that the bottom surface of the high-voltage switchgear is separated from the roller, ensuring that the high-voltage switchgear is in a stable state during the transfer process. During unloading, the same operation is adopted to make the roller contact the bottom surface of the high-voltage switchgear, and the unloading of the high-voltage switchgear is easily completed. Using this transfer vehicle not only reduces the difficulty of loading and unloading but also ensures the safety during transfer. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Principle and usage method of a transfer cart for high-voltage switchgear: When preparing to move a high-voltage switchgear onto the transfer platform, first adjust the height fine-tuning device, rotate the four adjusting blocks to lower the height of the transfer platform until the top of the rollers on the support platform extends out of the top surface of the transfer platform along the strip grooves. Control the electric lifting rod to lower the height of the entire top bracket so that the height of the transfer platform is flush with the height of the high-voltage switchgear to be moved. Move the high-voltage switchgear onto the transfer platform. At this time, there is rolling friction between the bottom surface of the high-voltage switchgear and the rollers. After the high-voltage switchgear is stable on the transfer platform, adjust the height fine-tuning device, rotate the four adjusting blocks to raise the height of the transfer platform until the bottom surface of the high-voltage switchgear is disengaged from the top of the rollers. Then control the electric lifting rod to lift the entire top bracket and push the transfer cart for transfer operations. After reaching the designated position, first control the electric lifting rod to lower the height of the top bracket until the height of the transfer platform is flush with the height of the unloading location. Rotate the four adjusting blocks again to lower the height of the transfer platform until the bottom surface of the high-voltage switchgear is in rolling contact with the rollers, and then easily unload the high-voltage switchgear from the transfer platform.
