Self-rotating carrying frame in-place machine

Abstract

The invention discloses a self-rotating carrying frame in-place machine and belongs to the technical field of transportation of a hydraulic support under a coal mine. In order to solve the technical problem, the invention provides the self-rotating carrying frame in-place machine through which the hydraulic support is conveniently transported and detached and which is low in cost, and the working efficiency is improved. The technical scheme is that one end of a frame is hinged with a lifting frame; a rotating piece is movably arranged above the frame; a central shaft is fixed in the middle of the bottom of the rotating piece; the other end of the central shaft extends to the lower part of the frame; piston rods of two transfer oil cylinders are connected with each other by moving around a steel wire rope on the lower part of the central shaft; a supporting piece is sleeved on the upper part of the central shaft; two shifting forks of a control fork are positioned in a groove formed on the frame; a control oil cylinder of the control fork is fixed below the frame; two parallel elongated grooves are formed on the bottom surface of the rotating piece; a plurality of elongated through holes are formed on the top surfaces of the grooves; each elongated through hole is provided with a second roller; and two transition plates, each of which the upper surface has a wave shape, are arranged in the two grooves. The self-rotating carrying frame in-place machine is used for transporting the hydraulic support under the coal mine.

Description

technical field [0001] The invention discloses a self-rotating frame transporting and positioning machine, which belongs to the technical field of underground hydraulic support transport 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 be solved...

Problems solved by technology

[0002] At present, the installation of the hydraulic support in the fully mechanized coal mine working face in domestic coal mines usually adopts the overall installation in place of the ground row. During the process, sometimes there will be abnormal situations such as damage to the body of the flatbed truck, non-rotating wheels, broken shafts, and wheels falling off.

Due to the limited underground conditions, the repair of the flatbed truck is time-consuming, laborious and inconvenient. The method of replacing the flatbed truck is often used, which reduces the work efficiency and increases the cost, causing inconvenience to the staff.
