The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Shown in Fig. 1,3,4, fully mechanized coal face described in the utility model termination tail advance support rack, comprise return airway advance support rack group and air intake lane advance support rack group, the arrangement of air intake lane advance support rack group is that two air intake lane advance support racks 10 join end to end, the side arm front end links to each other by the hydraulic cylinder on the base with elevating conveyor 11, and the after-frame rear end is connected by the hydraulic cylinder on the base with face end support 8; The arrangement of return airway advance support rack group is that three return airway advance support racks, 2 head and the tail link to each other by the hydraulic cylinder on the base, and the side arm front end links to each other by the hydraulic cylinder on the base with anchor support 1.Advance support rack comprises preceding back timber 13, back back timber 14 and preceding base 15 and rear base 16, is connected with hydraulic vertical prop 17 and two power bars 18 between preceding back timber 13 and the preceding base 15, is connected with hydraulic vertical prop and four power bars 19 between back back timber 14 and the rear base 16.
The advance support scope is 28 meters of rib precontracts.Return airway, air intake lane advance support rack structure identical (as shown in Figure 2).Advance support rack can adapt to the present situation that roof and floor has fluctuating, and maximum package length must not be greater than 6 meters.To guarantee during layout: the reasonable clearance between the two crossheading advance support racks, between advance support rack and face end support, the coal-winning machine; For guaranteeing coal mining efficient, when coal-winning machine runs to work plane one end and back production, only move an advance support rack and just can guarantee the space of mining; During advance support rack moved frame, extensible canopy was safeguarded the top board that exposes.
Advance support rack model and the quantity used in the actual production:
1 of anchor support 1:ZT3868/18/35 type anchor support
Advance support rack: 5 of ZT18330/18/35 type advance support racks (2 in air intake lane, 3 of return airways)
The supporting scope is not less than 20 meters before the two crossheading ribs, and elevating conveyor 11 outer width are 1330mm.End tail advance support rack will be realized bigger ventilation section, and center-aisle is not less than 2000mm.Frame adjustable range about transportation lane advance support rack will be realized greatly is with variation or the group's drum that satisfies span length.It is general that the advance support rack body frame wants to satisfy two crossheadings, and left and right sides work plane exchanges.Be convenient to the accessory management on the one hand, be not easy when installing simultaneously to make mistakes.
Tail side retaining wall 4: be installed on last last person's frame 5 side guard boards outside, 3 groups, the installation side retaining wall is 2 groups on the back timber side guard board, installs 1 group on the caving shield side guard board.Be mainly staff's supporting and go out a safe walkway.
Operating process during below for production:
1. air intake lane advance support rack operating process
------La 1# file leader frame------reach elevating conveyor (with from moving system's reach)------La is near adopting the face end support of face side---La is near the face end support of coal column side---coal-winning machine penetration of a cutting tool------La 1# advance support rack---La 2# advance support rack------La 1# file leader frame------reach elevating conveyor (with from moving system's reach)---face end support of---the close face end support of face side of adopting of La---the close coal column side of-La of receiving 2# advance support rack plate (for next circulation work of getting ready) that slips head behind the La that pushes away front slide toward the coal cutting of tail direction of receiving 2# advance support rack afterbody plate that slips head behind the La that pushes away front slide head that behind the saturating head coal of the coal mining machine cut side, returns 30 meters toward the tail direction
2. air return way advance support rack operating process
The coal mining machine cut is to tail during apart from about 1.5 meters of advance support rack plate, after receiving the saturating tail coal of 3# advance support rack afterbody plate----coal mining machine cut group,--------------------------------------------------the reach anchor frame----draws 1# advance support rack----to draw 2# advance support rack (for next circulation work of getting ready) to--drawing the 2# advance support rack---La 3# advance support rack (stretch out the afterbody plate, the small end tailstock is reach and then) to the reach anchor frame to reach 3# advance support rack (the small end tailstock is reach and then) to draw the 1# advance support rack to draw the back to slip tail to draw 1# last person's frame to slip tail before pushing away toward the heading coal cutting in coal-winning machine penetration of a cutting tool to draw the back to slip tail to draw 1# last person's frame to slip tail before pushing away to return about 30 meters toward heading
The utility model is at hydraulic prop or cooperate wooden frame to carry out the limitation of advance support, on the basis of using for reference the used hydraulic support of fully-mechanized mining working, has proposed the employing advance support rack and has replaced hydraulic prop and wooden frame to carry out advance support.Require advance support rack to satisfy coal-face advance support distance, supporting intensity and other safe clearances, and use efficient and conveniently, escape way is smooth and easy, the ventilation section is big, is beneficial to work plane and advances fast.Adopt advance support rack, improved the safety of producing greatly, break through the bottleneck of restriction fully-mechanized mining equipment performance maximal efficiency, solved roadway support hard nut to crack for many years, along with the quick raising of fully mechanized coal face mechanization degree and per unit area yield, ventilation, transportation and production practice to the crossheading cross dimensions require increasing.But traditional individual prop support pattern all can not adapt to the requirement of this high-yield and high-efficiency fully mechanized coal face to advance support from aspects such as support capacity, supporting height, support speed, automaticity processing safeties.Therefore, the support apparatus of development adaptation caving coal two crossheading advance supports requirement is significant.
