Background

The switch cabinet is an electrical device, the external line of the switch cabinet firstly enters a main control switch in the cabinet and then enters a branch control switch, each branch circuit is arranged according to the requirement of the branch circuit, and the switch cabinet is mainly used for opening, closing, controlling and protecting the electrical device in the process of generating, transmitting, distributing and converting electric energy of an electric power system.

In recent years, the number of power engineering projects is increasing, the engineering quantity is large, and the installation requirement of the switch cabinet is also increasing. The traditional construction method for installing the cabinet is that the switch cabinet is firstly moved to a trolley by manpower and then is transported to an installation position for installation. However, the traditional construction method needs a large amount of manpower for matching, and is poor in safety and stability.

Although equipment such as a forklift can be used for starting heavy objects in the existing market, the forklift is complex in operation, a main professional driver operates the forklift, and when the forklift moves, the moving distance and the positioning position are difficult to control accurately, so that potential safety hazards exist. The switch cabinet is usually in a frame structure, and the frame is usually formed by bending an iron sheet, so that the switch cabinet is poor in pressure resistance and extremely easy to deform. The whole switch cabinet is very heavy, and is usually hoisted by binding or lifting lugs during hoisting, but the binding mode easily enables the frame to be extruded and deformed, the lifting lugs welded on the frame generally cannot ensure uniform stress, and the stress position is mainly concentrated at the position of a hoisting point, so that the local deformation is caused. Not only can lead to the frame to warp and can't arrange the arrangement in order, but also can lead to inside device to take place to shift, contact is bad between the component, influences work efficiency even forms the potential safety hazard. If the hoisting point is close to the lower part, the gravity center of the switch cabinet is unstable and easy to be inclined, even turned over and fall, and safety accidents are caused. In addition, the cabinet body is easy to collide with during hoisting, and paint falling and deformation can also be caused.
