Description
Technical field
The invention belongs to corollary equipment behind the anchor driving machine, be specifically related to supporting stepped type fragmentation behind a kind of anchor driving machine, reprint continuous transport equipment.
Background technology
Anchor driving machine is a pick anchoring integral fast rapid-result lane equipment, and when adopting bolt support, to compare its superiority more outstanding with other heading equipments.The factor that influences anchor driving machine driving productivity ratio is a lot, and with regard to the equipment configuration, current domestic distinct issues are supporting transportation systems of choose reasonable and configuration back how, to reduce service working time, the production capacity of anchor driving machine are given full play to.
Anchor driving machine has two kinds of supporting forms at present:
1, corollary system behind shuttle car+feeding crushing machine+ribbon conveyer.
(1) system forms and arrangement
Its shuttle car is for coming and going mobile model storehouse formula material rehandle facilities.The feeding crushing machine is an automatic moving type fixed point working equipment, has the broken and reprinting function of material concurrently.Ribbon conveyer is extensible formula material transfer equipment.With respect to anchor driving machine, vertical order of placement is followed successively by shuttle car, feeding crushing machine, ribbon conveyer to these three kinds of equipment along the tunnel.
Feeding crushing machine and ribbon conveyer linearly are arranged in tunnel one side, and feed, fragmentation, conveying and discharging task are finished in the shuttle car operation of shuttling back and forth between anchor driving machine and feeding crushing machine.The maximum of the shuttle car stroke that shuttles back and forth depends on its cable rolling capacity, and equals the permission ultimate range between feeding crushing machine and anchor driving machine; Permission minimum range between feeding crushing machine and anchor driving machine is decided according to shuttle car length.System is the periodic duty mode, and each effective working cycles originates in the closest approach of feeding crushing machine apart from anchor driving machine, ends at its solstics.Forward move the feeding crushing machine and extend ribbon conveyer, begin new headwork circulation to new working cycles section start thereafter.
(2) problem of system's existence
Corollary system is adapted to span length greater than 4.5m behind shuttle car+feeding crushing machine+ribbon conveyer, and more than the head-room 3m, the gradient is less than the two lanes of the list in 12 ° mine driving.This supporting mode anchor driving machine remains straight line moving, need not back and forth movement, but shuttle car when feeding crushing machine haul, anchor driving machine stops discharging, belongs to interrupter duty.Be that the shuttle car in each working cycles comes and goes haul time and discharge time the non-cutting time in the system works, and time of crushing engine reach drawstring formula conveyer between each working cycles.The anchor driving machine of non-cutting time all is in the state that stops discharging, influences its production efficiency.And owing to also do not have ripe production domesticization shuttle car at present, so its accessory seeervice cycle is long, the input cost height, management difficulty is big.It is exactly that shuttle car has towing cable that this system also has a shortcoming, the speed of travel big (130m/min), and travel and have potential safety hazard in the down-hole.
2, corollary system behind belt elevating conveyor+ribbon conveyer
(1) system configuration and technology
The elevating conveyor storage end of this back corollary system is connected anchor driving machine frame afterbody, and delivery end rides on the ribbon conveyer tail section guide rail by walking dolly, and complete machine is bridge shape and moves with anchor driving machine.The permission range of belt elevating conveyor on the ribbon conveyer guide rail is called effective overlap joint stroke.Anchor driving machine is the starting point of the effective working cycles of system apart from the ribbon conveyer tail when nearest, and after elevating conveyor was covered effective overlap joint stroke, anchor driving machine stopped driving.After system finished an effective working cycles, anchor driving machine retreated into original position, made elevating conveyor produce an effectively overlap joint stroke again.Next anchor driving machine is moved conveyer tail section to new position together with elevating conveyor, finishes simultaneously and extends required all back works finished of ribbon conveyer, prepares for beginning next working cycles.
Corollary system is applicable in the single entry driving work of any anchor driving machine work behind belt elevating conveyor+ribbon conveyer.This supporting form structure is simple, and input cost is low, and operation is drawn and moved easy to maintenancely, has realized the production of working continuously in each circulation substantially.
(2) problem of system's existence
1., the direct supporting belt elevating conveyor of anchor driving machine uses, because the belt elevating conveyor does not have broken function, often scratches conveyer belt when the bulk coal petrography that produces in the anchor driving machine coal cutting process is unloaded on the belt elevating conveyor, has potential safety hazard;
2., the instantaneous coal amount of anchor driving machine is up to 1500t/h, if dispose the belt elevating conveyor of corresponding freight volume, then because of its fuselage ghost image stability of ringing anchor driving machine too; As dispose little freight volume belt elevating conveyor, then do not match;
3., the anchor driving machine chassis is low, conjointly the crack is little with the belt elevating conveyor, the bad adaptability that base plate is risen and fallen;
4., the anchor driving machine fuselage 90t that weighs, need to retreat drawstring formula conveyer after a working cycles is finished, increased service working time, influence anchor driving machine production efficiency, and heavy damage base plate.
Summary of the invention
The present invention for solve in the prior art behind the anchor driving machine supporting form exist non-cutting time long, influence anchor driving machine production efficiency, have the problem of potential safety hazard, supporting stepped type fragmentation behind a kind of anchor driving machine, reprinting continuous transport equipment are provided.
