Gantry crane cable stringing mechanism

Abstract

The invention discloses a gantry crane cable stringing mechanism, and particularly relates to the technical field of cable stringing, the gantry crane cable stringing mechanism comprises a plurality of transverse stabilizing rods and a plurality of stand columns, and the upper end of the front side face of each stand column is fixedly provided with a supporting transverse rod; a cable; the device comprises two first pulley shafts and two first pulleys, the two first pulleys are rotationally connected with the two first pulley shafts respectively, a main suspension steel wire rope is arranged on the two first pulleys, and the left end and the right end of the main suspension steel wire rope are both fixedly connected with first heavy hammers. The device comprises two first pulley shafts, two second pulley shafts and two second pulleys, the two second pulleys are rotationally connected with the two second pulley shafts respectively, the two second pulleys are provided with auxiliary suspension steel wire ropes, and the left ends and the right ends of the auxiliary suspension steel wire ropes are fixedly connected with second heavy hammers. The device has the advantages of being convenient to install, low in use cost, free of influence of rain and snow weather, resistant to water soaking, electric shock and cable dragging abrasion, capable of eliminating dragging power consumption and capable of automatically pre-tightening and correcting the sag of the cable, and is worthy of being greatly popularized.

Description

technical field [0001] The present invention relates to the technical field of cable wiring, and more particularly, to a gantry crane cable wiring mechanism. Background technique [0002] At present, gantry cranes in outdoor freight yards and processing yards mostly use the method of erecting sliding contact lines, wire rope hanging cables, sliding rail hanging cables or cable reels to lay directly on the ground. In use, it is easy to leak electricity due to the influence of rain and snow, and the sliding contact line needs to be maintained and replaced frequently due to sliding contact friction during use. Therefore, the sliding contact line is generally suitable for indoor workshops; the use of wire rope hanging cable, the flat hanging cable cost is high, The sag of the wire rope cannot be corrected by pre-tightening, and it is not suitable for use in freight yards with long running tracks. The longer the running track, the greater the sag of the wire rope, which will cons...
