Special lift truck for rheological installation of 12 kV switch cabinet

Abstract

The invention discloses a special lift truck for rheological installation of a 12 kV switch cabinet. The special lift truck comprises a frame, a rheological installation platform and a lifting mechanism for controlling the rheological installation platform to move up and down; the lifting mechanism comprises a lead screw and a nut, the lead screw is rotatably arranged in the frame, the nut is matched with the lead screw in a threaded mode, and a control mechanism used for driving the lead screw to rotate is arranged at the end of the lead screw; and the rheological installation platform comprises a base and a platform rotating mechanism, the base is fixedly connected with the nut, the platform rotating mechanism sequentially comprises an upper plate, a rotating disc and a lower plate, thelower plate is fixedly arranged on the base, and the rotating disc is arranged between the upper plate and the lower plate, so that the upper plate can rotate relative to the lower plate. The speciallift truck is small in size, simple in structure, suitable for being used in a narrow space, capable of coping with various construction sites, and capable of saving labor cost and improving installation efficiency while guaranteeing safety during rheological installation.

Description

technical field [0001] The invention relates to the technical field of rheological installation of 12kV switch cabinets, in particular to a special lifting vehicle for rheological installation of 12kV switch cabinets. Background technique [0002] The 12kV mid-mounted switchgear is the most widely used and most mature power equipment in the 10kV power system. When producing this switchgear, its incoming and outgoing line cabinets need to be installed with rheological transformers (current transformers, CT) in the cabinet. In some structures, rheology is installed on the rear beam of the cabinet, and in other product structures, the rheology is installed on the side of the cabinet or behind the middle partition. The rheology of 12kV has a large volume, and the weight can reach 20 kg to 30 kg. Currently, it is used Manual force for installation. [0003] Due to the small space available for installation inside the switchgear (the width of the switchgear is 650mm, 800mm, and t...

AI Technical Summary

Problems solved by technology

Generally, there are 2 to 3 rheometers in one switchgear, and more than 20 switchgears in one engineering project, so the installation workload of rheology is very large. Dangerous actions such as hugging and lifting during the installation process must not be leaked during the installation process. The workers have been bearing the full weight of the rheology, and there is a great potential safety hazard

To sum up, artificial rheological installation has the following disadvantages: poor safety performance, high labor cost, low work efficiency, etc.

The disadvantage is that it is not possible to work in places such as lower places and narrow aisles. Even a small hydraulic lifting platform is not enough to be used in the existing 12kV switchgear due to its own volume and device structure limitations.
