technical field

The invention relates to the field of electric equipment transportation, in particular to a switch equipment handling tool.

Background technique

In order to meet the needs of the rapid development of the modern economy and society, it is often necessary to carry out infrastructure construction and technical transformation of substations. Now smart substations use metal armored central removable switchgear, hereinafter referred to as central cabinet. This type of switchgear integrates protection measurement and control devices, instruments, circuit breakers and other devices. It is heavy and difficult to move and carry. Therefore, in the process of infrastructure construction and technical transformation of substations, the speed and quality of the central cabinet transportation and installation will directly affect the progress and quality of the entire project.

At present, we mainly use two methods for the transportation of the central cabinet: one is to use hydraulic carts for transportation; the other is to use the "roller" method for transportation. These two methods have the disadvantages of requiring a sufficiently large steering wheelbase, being limited by space, and easily damaging the center cabinet during transportation. Therefore, the development of a new type of metal central cabinet mobile installation device can shorten the installation time of the central cabinet, reduce the power outage time of users, improve user satisfaction, and create huge economic and social benefits while ensuring the installation quality.

The front end of the bracket is equipped with a lifting fork 2 for lifting the cabinet. The two brackets are connected as a whole through the height adjustment bracket 6, and the height adjustment bracket 6 is installed on the lifting device. In order to facilitate the adjustment of the direction of the lifting fork 2, a direction adjusting rod is installed on the upper end of the lifting fork 2.

The concrete structural principle of hoisting device, sucker device is as follows. The height adjustment bracket 6 is embedded with a lead screw nut 1. Leading screw 7 is installed vertically, and its lower end is connected on the base 15 by flat bearing. The middle part of leading screw is equipped with leading screw nut 1, and leading screw rotation can drive leading screw nut 1 to translate up and down and then drive height adjustment support 6, finishes lifting fork 2 to move up and down.
