　　1、 Characteristics of JH-8 column winch

　　1. The JH-8 column winch adopts a single cylinder winding form, using a turbine reducer and an open gear transmission. Symmetrically arranged in a long strip shape, the top pillar (fixed) position is spacious, making it easy to move and fix the winch.

　　2. The width and height dimensions of JH-8 column winch are relatively small, making it suitable for underground use.

　　3. Using spherical worm gear for smooth operation. The structure is simple, easy to maintain, and easy to operate, as long as the on/off button is pressed.

　　4. Electric motors and electrical equipment have explosion-proof performance and can be used in mines containing biogas and coal dust with ambient temperatures not exceeding 35 ℃.

　　Lubrication of Three JH-8 Type Backcolumn Winch

　　The lubrication of a machine is not only related to its normal operation, but also directly affects its lifespan, so it is necessary to replace and replenish lubricating oil in a timely manner. The material of lubricating oil must meet the requirements and must not be mixed with impurities such as dust, dirt, iron filings, and water.;

　　In order to lubricate the worm gear and rolling bearings inside the worm gear box, 24 cylinder oil is injected into the worm gear box, so that the oil level is frequently immersed in the lower teeth of the worm gear, and it is checked once a day and replenished in a timely manner. The oil quality of the worm gear box must not be changed arbitrarily, otherwise it will cause a sharp increase in oil temperature inside the box, exacerbate worm gear wear, and reduce transmission efficiency.

　　Small gears, bridge gears, and large gears should also be lubricated with the above oil quality. Oil should be added at least once per shift to maintain a layer of oil film between the tooth surfaces.

　　The bearings inside the drum should be lubricated with calcium sodium based grease every 3-6 months. The refueling amount should not exceed 2/3 of the bearing capacity. For new or overhauled winches, especially those with updated worm gear, the lubricating oil must be replaced after 8-10 days of operation to remove metal shavings from worn parts.

　　In summaryJH-8Type return column winchIt is a traction device used for the relocation and installation of comprehensive mining equipment and working faces in coal mines, especially suitable for thin coal seams, medium thick coal seams, and steeply inclined coal seam working faces. It can also be used as traction for auxiliary work such as material transportation, chute and belt conveyor heads in tunnels with an inclination of less than 30 °.
