Technical Field

The utility model relates to the technical field of hydraulic column hoisting, in particular to a hydraulic column hoisting device.

Background Art

The hydraulic support is a structure used to control the pressure of the coal mining face. The underground roof of the fully mechanized mining face acts on the hydraulic support in the form of external load. The hydraulic support consists of hydraulic columns, jacks, roof, guard plates, tail beams, connecting rods, and bases. The main supporting role is played by the hydraulic columns acting on the roof to support the coal mining face. During the long-term use of the hydraulic columns underground, the surface of the columns rusts, peels, and falls off, resulting in leakage and fluid channeling of the hydraulic columns. Therefore, the hydraulic columns need to be regularly maintained.

The maintenance frequency is high and the weight is heavy. The live column holes are divided into through holes and blind holes. In the process of repairing the columns with blind holes at the live column heads, there are many safety hazards in the lifting process. Traditional lifting methods include using lifting belts and lifting rings on the surface of the hydraulic column body. Both are prone to the problem of top-heavy lifting, which brings serious safety hazards to the maintenance process.
