Problems solved by technology
[0002] The winches used in the underground working face and roadway are generally fixed by concrete foundations, and the winches that are often moved or temporarily used are usually fixed and supported by logs. Since the length of the logs is certain, the winches will not be pulled by traction. , the initial support force of the log between the roof and the winch is very small, and some roadway roofs are not hardened, and the coal body is relatively soft. The displacement makes the log lose its fixed support function, makes the overall support of the winch invalid, and even leads to transportation accidents; the scraper conveyor is a mechanical device that moves frequently, so the log is generally used as a pressure column to fix the head and tail. Also because the length of the log is fixed, there is not enough initial support force, and the scraper conveyor is always in a state of vibration when it is working, so the effect of using the log alone to fix the support is not very good

The invention relates to a pressure column jack lifter device, which belongs to the technical field of mechanical lifting devices such as coal mine underground winches, scraper conveyors and the like for fixing and supporting. The pressure column jack lifter device is small in structure, convenient and safe in use and firm in fixing. The technical scheme includes: the pressure column jack lifter device comprises a bottom boot, a bottom boot sleeve, a jack, a round timber connecting seat and a round timber sleeve cover. The bottom boot is structurally characterized in that a cylinder is vertically fixed above a bottom plate, the bottom boot sleeve is cylindrical and sleeved outside the cylinder, the lower end of the bottom boot sleeve contacts with the bottom plate, the upper end of the bottom boot sleeve is welded below the jack, the round timber connecting seat is mounted at the upper end of the jack, and the round timber sleeve cover is perpendicularly positioned above the round timber connecting seat. The pressure column jack lifter device is used for fixing and supporting the round timber.
