Combined pulley type cable hook in coal mine

Abstract

The invention provides a combined pulley type cable hook in a coal mine. A floating cable in the coal mine is hung in the combined pulley type cable hook so as to save time and efforts while the cable moving and putting up and down. The combined pulley cable hook in the coal mine can expand the number of connections by a combined mechanical connection expansion; the pulley type cable hook by one-way bearing is mechanically connected to a pulley shaft; the pulley shaft is mechanically connected to combined supports; among the cable pulley and the pulley shaft is mechanically connected through a one-way bearing capable of adjusting rotation direction; among the combined supports is mechanically connected by metal articulated. The combined pulley type cable hook can be used according to the working conditions combination of coal mine, the coal mine floating cable is hung in the combined pulley cable hook, a pulley rotated with a cable minimizes the frictional force between the cable and the cable hook while the cable moving and putting up and down. The combined pulley type cable hook can adjust the rotation direction of the cable and the pulley according to the high drop of tunnel of coal mine working face, and reverse and stop with rotation of opposite direction to prevent the cable sliding back to the low spot while moving and recycling from low to high.

Description

technical field [0001] The invention relates to a coal mine combined pulley type cable hook, in particular, the coal mine mobile cable is suspended in the combined pulley type cable hook, which saves time and effort when the cable is moved and retracted, and the coal mine combined pulley type cable hook adopts a combined mechanical connection expansion, which can expand the connection Quantity, it can be used in coal mine roadway that needs to be moved and retracted for cable suspension. Background technique [0002] At present, the rubber-sheathed cables that need to be moved in the coal mine working face are suspended in the traditional cable hooks. When the coal mine working face moves and retracts the cables, it is necessary to manually separate the cables from the cable hooks, place the cables on the floor of the coal mine roadway, and drag them manually or mechanically. After the cable is retracted, the cable is manually suspended in the cable hook. Using the tradition...

[0002] At present, the rubber-sheathed cables that need to be moved in the coal mine working face are suspended in the traditional cable hooks. When the coal mine working face moves and retracts the cables, it is necessary to manually separate the cables from the cable hooks, place the cables on the floor of the coal mine roadway, and drag them manually or mechanically. After the cable is retracted, the cable is manually suspended in the cable hook. Using the traditional cable hook to move and retract the cable requires the cooperation of 2-3 workers to complete. The labor intensity of the staff is high, time-consuming and labor-intensive. Manual dragging or mechanical pulling The cable is easy to cause damage to the cable insulation, which is not conducive to the safe production of coal mines
