During coal-winning machine coal cutting, first mobile end hydraulic support, reserve forward pitch from, then, more mobile contiguous working surface hydraulic support one by one, until mobile complete working surface hydraulic support, finally move the face end support of another side.
During mobile hydraulic support, because have stay cord as benchmark, be convenient to " three is always flat " that realize work plane.Design like this, simple to operate, support accurate positioning, ensure that force piece moves past rear in alignment, for the smooth coal cutting of coal-winning machine creates condition, ensure that working face wall is in line, facilitates secure quality standardizatio construction.Secondly, substantially increase the efficiency that work plane moves frame, coal cutting, economize labor time, reduce labour intensity, improve the automatization level of thin coal bed fully-mechanized mining face, embody the design concept of hommization, active response builds the call of harmonious mine area.In addition, processing and manufacturing is simple, and cost is low, and what fully demonstrated economize expense and reduce expend uses material theory.In addition, convenient and practical, there is very large promotional value.
As optimization, the front portion of two end support alignment plates also has long slot bore, is provided with bolt in this long slot bore, and this bolt is fixed with end plate, and described stay cord end is fixed on the front portion of end support alignment plate by end plate.Design like this, stay cord can move forward and backward at end support alignment plate.
As optimization, the long slot bore both sides of the front portion of end support alignment plate have multiple locating hole.Design like this, is convenient to location.
As optimization, described stay cord is wire rope, and its two ends are fixed on end plate respectively by a flower basket bolt.Design like this, stay cord intensity is large, and degree of tightness is easy to adjust.
As optimization, also comprise multiple warning device, each warning device is located near an intermediate support alignment plate, this warning device comprises two levers, two explosion-proof contact switch, buzzer and/or LED, wherein two levers and two explosion-proof contact switch are fixed on below back timber, and two balance pivots are hinged, two proper front ends to explosion-proof contact switch of lever one, two lever other ends are located at stay cord both sides respectively, after two explosion-proof contact switch parallel connections, be connected into alarm circuit with buzzer and/or LED.
Design like this, when stay cord touches any side of lever one end, namely stay cord not point-blank time, the lever other end contacts explosion-proof contact switch, and buzzer is sounded or LED lights, remind stay cord not point-blank, be convenient to precise manipulation.
It is simple that the present invention has processing and manufacturing with the hydraulic support for low coal seam system of alignment device, the advantage such as convenient and practical, in addition, simple to operate, support accurate positioning, ensure that force piece moves past rear in alignment, improves the efficiency that work plane moves frame, coal cutting, be applicable to various colliery to use, be particularly suitable for thin coal bed fully-mechanized mining operation and use.
