The invention relates to a hydraulic support placing machine turntable device, belonging to the technical field of underground hydraulic support transportation for coal mines. The invention solves the technical problem of providing a hydraulic support placing machine turntable device which is convenient to transport and unload hydraulic supports and has low cost. The invention adopts the technical scheme that a rotating part is movably installed above a stand, one end of a mandrel is fixed in the middle at the bottom of the rotating part, and the other end of the mandrel stretches to be below the stand; piston rods of two transfer cylinders installed at the bottom of the stand are connected via one steel wire rope winding around the lower part of the mandrel, the lower part of the mandrel is sheathed with a supporting part, two shifting forks of a control fork are located in slots arranged on the stand on both sides of the mandrel, the bottom face of the rotating part is provided with two long parallel grooves, the top face of each groove is provided with a plurality of long through holes, one rolling column is installed in each long through hole, and two transition plates with upper waved surfaces are respectively installed in the two grooves. The hydraulic support placing machine turntable device is used for transporting and placing underground hydraulic supports for coal mines.
Description
technical field [0001] The invention relates to a turntable device for a hydraulic support positioning machine, which belongs to the technical field of underground hydraulic support transportation in coal mines. Background technique [0002] At present, the installation of the hydraulic support in the fully mechanized coal mine working face in domestic coal mines is mostly done by the overall installation of the ground row. In the process, sometimes there are abnormal situations such as damage to the body of the flatbed, non-rotating wheels, broken shafts, and wheels falling off. Due to the limited downhole conditions, it is time-consuming, labor-intensive and inconvenient to repair the flatbed trucks. The method of replacing the flatbed trucks is often used, which reduces the work efficiency and increases the cost, causing inconvenience to the staff. Contents of the invention [0003] The invention overcomes the deficiencies of the prior art, and the technical problem to...
