Problems solved by technology

[0002] There are many components on the crane, and some components require direct current. Therefore, in the case of connecting to alternating current, a current converter is needed, but most of the current converters have poor seismic performance, resulting in short life, fast depreciation of the crane, and increased production costs.

Abstract

The invention discloses a plant crane direct current line expander comprising a line expander body. A current converter provided with an adjusting knob is arranged at the upper end of the line expander body. The line expander body is provided with a first wiring port, a second wiring port, a third wiring port, and a current regulator. The line expander body has an anti-vibration structure, and the inner walls of the first wiring port, the second wiring port and the third wiring port are made of elastic plastic. The plant crane direct current line expander is a device fixed to a crane, and the line expander body has the anti-vibration structure, so that the expander can effectively resist the vibration from the crane, and the safety of the line is guaranteed. The inner walls of the first wiring port, the second wiring port and the third wiring port are made of the elastic plastic, so that the ports can be tightly connected, and a condition that the production efficiency is influenced due to poor contact of the ports is prevented.

Description

technical field [0001] The invention relates to an expander, more precisely, a DC line expander for a workshop crane. Background technique [0002] There are many components on the crane, and some components require direct current. Therefore, in the case of connecting to alternating current, a current converter is needed. However, most of the current converters have poor seismic performance, resulting in short life, fast depreciation of the crane, and increased production costs. Contents of the invention [0003] The invention mainly solves the technical problems existing in the prior art, thereby providing a DC line expander for a factory crane with a long service life. [0004] Above-mentioned technical problem of the present invention is mainly solved by following technical scheme: [0005] A DC line expander for a factory crane, comprising a line expander body, a current converter is provided on the upper end of the line expander body, an adjustment knob is provided o...
