Description
Technical field
The present invention relates to the suspension device of tunnel excavation operation in a kind of mining; The particularly a kind of means of mechanization and tunnelling alternating expression suspension device that the fully-mechanized digging machine coordinating operation carries out on-the-spot immediate support of adopting; Be mainly used in the top board that has just exposed of tunnelling operation and auxiliary lapping and the timely mechanization supporting of beating anchor pole etc., the shielding fully-mechanized digging machine is the operation of realization continuous supporting in certain zone, tunnel.Belong to mining machinery manufacturing and application.
Background technology
In the pit mining in present mining, especially colliery, the excavation operation in tunnel is the prerequisite of every other operation.Along with the comprehensive mechanized development machine generally use of (being called for short " fully-mechanized digging machine "), " drilling and blasting " operating type that the efficient of tunnelling is more traditional has had large increase.But, influenced by the back ROCK CONDITIONS, the driving technology that generally adopts is: just shut down when generally tunneling 1～2 meter, carry out artificial temporary lining with anchor pole, anchor cable or capplce etc., and then start is tunneled 1～2 meter, so cycle operation.This desultory cycle operation efficient is very low, makes excavation operation can't bring into play the advantage of fully-mechanized digging machine.Relevant data shows, even in, also less than 30% of the fully-mechanized digging machine Homes Using TV under the large-scale coal mine during tunnelling, that is have and surpass time of 2/3rds and all be used for artificial temporary lining.Its basic reason is exactly that existing tunnelling supporting means fall behind, and lacks and can screen fully-mechanized digging machine normally to tunnel, and the back that tunnels firm exposure is carried out the safety means of temporary lining simultaneously.Tunnelling has become the bottleneck that a lot of coal mining enterprises of restriction produce, and according to home and abroad related data report, does not still have the maturation of these type of safety means or technology at present and uses.Although China is since the last century the nineties; Some schemes of being devoted to address this problem have also appearred successively; But no matter on its design principle, still from application practice, reflect that all these schemes too theorize, far can not adapt to on-the-spot actual needs.
Existing excavation operation suspension device can roughly be divided three classes: the first kind is on existing development machine, to do some change; Temporary support device and fully-mechanized digging machine are integrated; Reaching the purpose of working continuously, is that " a kind of front-probe support of tunneling working face " of CN2204334Y, " advanced stand device of driving face ", notification number that publication number is CN101029570A are " dig, protect, anchoring integral heading equipment " of CN200964858Y etc. like patent announcement number for CN2782932Y " combining pick meets head on to visit temporary support device before the hydraulic pressure ", " supporting type continuous tunnelling machine ", notification number that publication number is CN1987046A.The suspension device that these and fully-mechanized digging machine are fixed together; Though solved the walking problem to a certain extent; But the huge vibrations that fully-mechanized digging machine produces in tunneling process also will directly act on the back of institute's supporting through suspension device; Quicken it and destroy, also produce various faults because of vibration easily with the fixing of fully-mechanized digging machine cut rocking arm or fuselage simultaneously; In addition, the supporting area and the effective support space of this structure are little, can not realize the full section supporting to digging laneway, still will rely on intermittent manual work, have certain potential safety hazard.
Second type is to adopt the capplce of parallel interval setting to add supporting leg (being mostly hydraulic prop), and mobile employing takes a step to move the structure of frame from moving or circulating: is that " driving is with flexible back timber temporary lining ", the notification number of CN2142883Y is " the heading end temporary lining special type hydraulic support " of CN2189645Y, " compressibile support that is used for roadway head " that notification number is CN2851578Y etc. like patent announcement number for " driving face falsework ", the notification number of CN2133672Y.Above patent all belongs to the structure of employing " slippage " back timber, and the support of this structure all is applied in the common fully mechanized workface as a kind of simple rack, presses little, the better simply coal seam of geological conditions that certain applicability is arranged for the ore deposit.This structure links together the auxiliary connection of two back timbers that are arranged in juxtaposition through the side usually side by side, links to each other with individual prop under the back timber, and individual prop acts directly on the base plate.The support of this form of structure relies on the passing jack that is arranged between two back timbers arranged side by side or is positioned at the back timber bottom, and the push-and-pull back timber moves ahead each other, but moving of it must be by adjacent supports back timber or other transversing gears carry out slippage with it.The problem that these suspension devices mainly exist: the one, can not solve the support stability problem when moving behind the frame supporting again well; The 2nd, meet that the tunnel rises and falls or base plate when softer, it is difficult that this class formation tends to move the frame supporting, the problem of supporting leg " at the bottom of the bundle "; The 3rd, can't solve development machine immediate support problem foremost, be difficult to the top board that heading end has just exposed is carried out effective immediate support.
The 3rd type then is the form of structure that adopts a plurality of unit racks; Be the grafting form that " hydraulic support that is used for roadway head " of CN100365244C proposes like patent announcement number, be the stable and supporting of support and move advantage is provided, but the form of structure of this grafting; Make the whole broad of support; The layout that is unfavorable for fully-mechanized digging machine between frame, the two coordinating operation and walking also receive certain influence, and of this patent; Permanent support still needs to carry out at the front end of support, does not fundamentally change the work pattern of fully-mechanized digging machine.And patent announcement number designs for solving " big gun pick " work plane for the technical scheme of CN2890341Y " driving hydraulic prop support ", can't carry out supporting operation with fully-mechanized digging machine.Patent announcement number be propose in " necessary support frame before heading face " of CN1035025C by splicing before and after a plurality of unit racks; The form of structure of forming a whole set of support; Attempt back and two is helped to realize totally enclosed supporting; But find that in practical application this supporting structure exists supporting and can't guarantee with the stability that moves, deficiencies such as installation in the narrow lane space in down-hole, dismounting and inconvenient maintenance.
