Abstract

The invention relates to the technical field of gantry crane power supply devices, in particular to a gantry crane sliding contact power supply device and a power supply method. The device comprises an electricity connection rotary shaft, a first shaft bracket, a second shaft bracket, shaft sleeves, conical sealed parts, shaft sleeve end covers, shaft bracket fixing parts, a press plate, press plate springs and a lifting adjustment assembly. The shaft sleeves are fixedly connected to the left end and the right end of the electricity connection rotary shaft respectively. The two shaft sleeves are arranged oppositely. A plurality of conical sealed parts are in sliding connection with the inner end of each of the two shaft sleeves. The multiple conical sealed parts are arranged on the electricity connection rotary shaft in a covering manner. The inner end of each shaft sleeve is fixedly connected with a shaft sleeve end cover. The shaft bracket fixing parts are fixedly connected with theupper end of the first shaft bracket and the upper end of the second shaft bracket respectively. The press plate is connected to the upper ends of the shaft bracket fixing parts in a sliding manner. Each press plate spring is arranged between the corresponding shaft bracket fixing part and the corresponding press plate. The press plate is connected to the lifting adjustment assembly in a sliding connection manner through threads. According to the gantry crane sliding contact power supply device and the power supply method, the electricity connection rotary shaft can be prevented from being corroded by rain or sunshine, and false connection is avoided.

Description

technical field [0001] The invention relates to the technical field of power supply for gantry cranes, in particular to a sliding contact power supply device and a power supply method for gantry cranes. Background technique [0002] For example, the patent application number is CN200910301665.5, a 50T gantry crane trolley line mobile power supply device, the trolley line is suspended and fixed by the sliding contact unit, and connected to the power supply line of the gantry crane, each sliding contact unit includes a contact slider, There are three parts of the connecting piece and the suspension. The lower part of the contact slider has two sliding contact rollers with grooves on the rim. The sliding contact wires are erected in the grooves of the two sliding contact rollers. The two sliding contact rollers The wheel axle is connected between the FRP insulating plates on both sides, and the upper outer surface of the FRP insulating plate is connected to the flat iron by bol...
