Installation of hydraulic support and frame adjustment device for eye cutting in fully mechanized fully mechanized caving coal mining face

Abstract

The invention discloses a fully mechanized coal mining and caving work face open-off cut mounting support adjusting device and solves the outstanding problems of unloading, rotating and adjusting after the a support enters an open-off cut. The device comprises a base disc, a rotary table, a transition table, a transition table guide groove and a hydraulic system. The base disc comprises cases on two sides and an H bar which is connected between the two cases through bolts; a connecting rail is paved on the the H bar, the right ends of the two cases are provided with pushing seats, support disassembling jacks are hinged to the pushing seats through shafts with the fai 50, and piston rods of the support disassembling jacks are hinged to pushing caps. By the aid of the coal mining work face open-off cut mounting support adjusting device, the outstanding problems of unloading, rotating and adjusting after the a support enters an open-off cut are solved, the support adjusting manner that a winch matches with a monomer is changed, and the prospective effect is achieved through practice; currently, forming equipment of the coal mining work face open-off cut mounting support adjusting device is not provided, and the device fills the gap.

Description

technical field [0001] The invention relates to a mine engineering machine. Background technique [0002] Four types of commonly used hydraulic supports, ZY2400, ZZ4400, ZF7000, and ZF9000, are frequently installed on the working surface, with 4-6 installation tasks per year, and the installation schedule is tight and the tasks are heavy. [0003] Due to the large size and heavy tonnage of the hydraulic support, it determines that during the installation process of the coal mining face, the installation of the support is the focus and difficulty of the entire installation task. Analyzing the installation process, it is not difficult to find that the support is unloaded after entering the cutting hole , The frame adjustment seriously restricts the installation progress of the bracket. The installation method of the hydraulic support in the traditional fully mechanized (opening) coal mining face is: the track is laid in advance for the cut eye, and the winch is installed at t...

AI Technical Summary

Problems solved by technology

The work efficiency is low, which seriously restricts the installation progress of the working face

[0005] In view of the existing problems, design the hydraulic support adjustment device for the cutting eye of the fully mechanized mining (opening) coal mining face, focus on solving the outstanding problems in unloading, rotation, and adjustment after the support enters the cutting eye, and change the adjustment method of the winch and the single unit , Practice has proved that the expected effect is achieved; at present, there is no forming equipment for the installation of hydraulic support adjustment devices for cutting holes in coal mining face, and the development of this device fills this gap
