Problems solved by technology

After this kind of pulley frame runs for a period of time, the cable will be stretched and deformed under the action of tension and will be in a slack state. At this time, it is easy for the cable to jump radially or swing axially along the pulley, causing the cable to come out of the pulley groove. If it is worn or twisted, if it is not found in time, there will be faults such as cable short circuit or grounding, which will affect normal production and even cause safety accidents.

Embodiment Construction

[0011] Such as Figure 2~Figure 4 As shown, an anti-cable pulley frame device for a gantry crane includes a pulley frame 2 and a pulley 1, and a plurality of V-shaped support plates 3 and V-shaped support plates 3 are installed at both ends of the pulley frame 2 A shaft 4 is fixedly installed by bolts, and a roller 5 is arranged on the shaft 4 . On the described tackle frame 2, adjacent to the position of the pulley 1, a plurality of L-shaped suspension plates 6 are fixed, and the plurality of L-shaped suspension plates 6 are fixed on both sides of the tackle frame 2 by bolts. The bottom of the arbitrary block L-shaped hanging plate 6 is provided with a supporting shaft 7, on which a roller 8 is installed, and a dividing plate 9 is arranged between two adjacent rollers 8.

[0012] A V-shaped support plate 3 is made of a steel plate, and it is fixed on the pulley frame 2 on both sides of the pulley 1 by bolts. In order to prevent cables or wire ropes from protruding from the p...

Abstract

The invention discloses a cable disengagement-proof pulley rack device for a portal crane. The pulley rack device comprises a pulley rack and a pulley, wherein V-shaped mounting plates are mounted at the two ends of the pulley rack; a shaft is mounted on the V-shaped supporting plate; a roller is arranged on the shaft; a plurality of L-shaped hanger plates are fixed on the pulley rack; supporting shafts are arranged at the lower parts of all L-shaped hanger plates; rolling shafts are mounted on the supporting shafts; separation plates are arranged between every two adjacent rolling shafts. The cable disengagement-proof pulley rack device for the portal crane can effectively avoid a phenomenon that the cable is disengaged from a pulley groove to be abraded or broken, and is beneficial to ensure regular production and reduce the production cost.

Description

technical field [0001] The invention relates to the field of hoisting machinery, in particular to an anti-cable pulley frame device suitable for gantry cranes. Background technique [0002] At present, the trolley of the MDG gantry crane is usually powered by a cable trolley frame, that is, the cable is installed on the trolley frame on the upper part of the crane girder, and then introduced into the trolley to connect with the motor. This kind of pulley frame is mainly composed of a connecting frame and multi-groove pulleys fixed at both ends. The cables are wound on the pulleys at both ends, and are pulled by wire ropes to move back and forth on the girder with the walking trolley. figure 1 shown. After this kind of pulley frame runs for a period of time, the cable will be stretched and deformed under the action of tension and will be in a slack state. At this time, it is easy for the cable to jump radially or swing axially along the pulley, causing the cable to come out ...
