Embodiment Construction

[0037] Examples see figure 1 , figure 2 As shown in the mobile power supply device of the trolley line of the gantry crane, 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 three parts: the contact slider, the connecting piece and the suspension .

[0038] see image 3 As shown, the lower part of the contact slider has two sliding contact rollers 1 with grooves on the rim, the sliding contact line 6 is erected in the grooves of the two sliding contact rollers 1, and the axles of the two sliding contact rollers 2. Connect between the glass fiber reinforced plastic insulation boards 3 on both sides, the upper outer surface of the glass fiber reinforced plastic insulation board 3 is connected with the upper flat iron 5 by the bolt 4; The FRP insulating board 3 is two boards or an inverted U-shaped board.

[0039] see figure 1 , figure 2 , Figure 4 As shown, ...

Abstract

The invention relates to a 50T gantry crane sliding contact line mobile power supply device. A sliding contact line is suspended and fixed by sliding contact units and connected to a power supply line of a gantry crane, each sliding contact unit comprises three parts, namely, a contact sliding block, a connecting part and a suspension frame, two sliding contact rolling wheels with grooves at the wheel rims are arranged at the lower part of the contact sliding blocks, the sliding contact line is erected in the grooves of the two sliding contact rolling wheels, a wheel shaft of the two sliding contact rolling wheels is connected between glass steel insulating plates on the two sides, and the outer surfaces of the upper parts of the glass steel insulating plates are connected with an upper flat iron by bolts. A set of sliding contact power supply system consists of three contact sliding blocks which are transversely arranged and connected with the suspension frame by the connecting part, and the suspension frame is connected with a support on the gantry crane. The sliding contact line mobile power supply device can meet the power supply demand of the gantry crane during the operation, has the advantages of low cost, low failure rate, simple and convenient installation and operation and the like, and can be used in a beam yard gantry crane power supply system.

Description

technical field [0001] The invention relates to a gantry crane power supply system, in particular to a gantry crane mobile power supply device. Background technique [0002] The known gantry crane power supply system adopts the reel power supply scheme: each gantry crane is equipped with more than 1,000 meters of 5-core cable, and the cable material costs hundreds of thousands of yuan; each gantry crane needs two workers to watch the line, and has a complex structure and durability Defects such as poor performance, high labor costs and high costs. At present, the trolley line power supply methods of cranes are as follows: fixed bare steel trolley line, suspended trolley line and insulated safety trolley line. Most of the suspension trolley lines use double-groove copper trolley wires, which are relatively reliable in operation, and have the advantages of simple structure, durability and ease of use, and low cost. Contents of the invention [0003] In order to overcome th...
