Description
The utility model relates to a kind of coal mine fully-mechanized mining working usefulness, particularly inclined seam horizontal type end hydraulic support.Back timber, base, column are arranged.
Coal mine fully-mechanized mining working faces end head is the roof pressure district that crosses, and equipment is many, is again the emergency exit.Therefore, safeguarding the termination is the major issue that is related to safety in production.At present, the many employings of gentle dip fully mechanized coal face end support are moved towards the formula end hydraulic support and are come supporting, are generally offset and middle-set-type.The problem that adopts this support is difficult in maintenance for the trigonum between end hydraulic support and transition bracket, does not still have the way of properly settling.Large-inclination-angle coal bed fully mechanized coal face termination management difficulty is bigger more than 35 °, moves towards the formula end hydraulic support and can't use owing to can't overcome the horizontal thrust that causes at the inclination angle.To this fully mechanized coal face, can only use individual prop and back timber to carry out supporting, can not carry out the mechanization supporting effectively.A kind of horizontal type end hydraulic support that is used for arched tunnel is arranged, its design feature be have on the base make that support laterally moves move the frame jack.Back timber has the bi-directional movable side guard board, and extensible canopy.Caving shield is a shaped form, and two ends are hinged with base and back timber respectively.This support need not replace canopy by several multistage supportings, laterally moves successively, and it is long to have solved general end hydraulic support back timber, passes the too big shortcoming of resistance.But, therefore still can not solve above-mentioned more large-inclination-angle coal bed end support problem because the structure of its caving shield and back timber can not adapt to the variation of trapezoidal tunnel and coal seam angle.
The purpose of this utility model provides a kind of end hydraulic support applicable to more large-inclination-angle coal bed fully mechanized coal face.
The purpose of this utility model can reach by following measure:
The utility model is a kind of horizontal type end hydraulic support, and one group of end hydraulic support can be formed by 2～5.Between top beam rear end and the base rear portion lifting gear is arranged.The two ends up and down of lifting gear are hinged with back timber and base respectively.The column two ends are hinged with back timber and base respectively.Be equipped with on the back timber and transfer the frame jack.By regulating the length of lifting gear and column, back timber can be with head-room and seam inclination and lifting and angle changing.Make end hydraulic support can not only adapt to gently inclined seam, can also adapt to 35 °～45 ° large-inclination-angle coal bed variations.
Lifting gear comprises several box-shaped elevating lever and seat-boxs, the upper end and the back timber of box-shaped elevating lever are hinged, and insert in the seat-box lower end, in box-shaped elevating lever that has and the seat-box lifting jack is installed, the two ends of lifting jack are hinged with set cap and base respectively, the control lifting.
Be used for when large-inclination-angle coal bed, first of the following file leader of force piece can not be too near to down crossheading, just can safeguard trigonum between force piece and the face end support so need to increase the length of back timber.For this reason, extensible canopy can be installed, also lengthening bar can be installed in the extensible canopy front in the back timber front.Extension bar is installed between lengthening bar and the base plate, supports jack and backing board, play a supportive role.
For making side guard board can screen top board effectively when moving frame, can make the side guard board between major and minor is the active side backplate.The active side backplate is hinged with the tailpiece of the piston rod of separately thruster jack respectively, and the other end of thruster jack is hinged with this fixation side backplate respectively.Two thruster jack, to motion mutually, when making face end support traversing, the active side backplate can screen the space of a step pitch.
In addition, the utility model has also been set up some annexes, comprises that retaining cash coal passing plate, retaining cash connect coal plate, waste rock board, back waste rock board, side waste rock board and fly down frame etc., to increase the face end support performance.
The utility model compared with prior art has following advantage:
Owing between top beam rear end and the base rear portion lifting gear is arranged, makes back timber carry out lifting and angle changing with the variation of head-room and seam inclination.Simultaneously, back timber is equipped with extensible canopy and lengthening bar, setting up of the improvement of side guard board structure and various annexes, make the utility model can adapt to the variation of head-room and seam inclination, solve the supporting of V-belt between inclined seam force piece and the end hydraulic support, maintenance work face termination top board ensures safety in production effectively.
