Description

Roadway is dug the advance support integration unit soon
Technical field
Support apparatus when the utility model relates to excavation is specially a kind of roadway and digs the advance support integration unit soon.
Background technology
Topmost mode is boom-type roadheader and MQT series jumbolter in China's tunnel speedy drivage mode, SPJ-650 type rubber conveyer supporting technology production line, be also referred to as tunnel comprehensive mechanized driving, but combine flat still the pacing up and down about 350 meters of the single water inlet of pick.The leading temporary lining safety problem of tunnelling is a puzzlement Coal Production technical barrier for many years.The temporary lining form of generally mentioning use in the domestic coal mine roadway driving is that suspension ring (U type card) string beam and pillar add two kinds of support forms of crossbeam, this dual mode all exists unreliable, the potential safety hazards such as operation easier is big, supporting intensity is low, empty top zone anchoring operation of safety, use construction technology of a pick, the cycle operation time is long, and the restriction drivage efficiency improves.Along with the development of combining the technology of adopting, domestic annual output millions of tonnes even the super work plane of ten-million-ton scale of having occurred, make year to consume stope drift active workings quantity and increase considerably, and comprehensive mechanized driving speed does not far satisfy the colliery digging and takes out loose smooth and easy, the lifting of link ability of linking, the requirement of stable high yield security developments now.So the measure that take in domestic colliery is to increase the group solution digging of driving team to be connected nervous situation, yet driving team group is in order to pursue drilling depth, it is long operation operation, the operation of override top, supporting untimely, empty top time often to occur striding, and anchor-holding force of anchor bolt do not reach the supporting requirement, not according to phenomenons of operating against regulations such as regular loop organization productions.Therefore, need that a kind of volume is little, structure is simple relatively, dependable performance, simple installation, simple to operate, the manually operated utility model mill auxiliaries device that is suitable for the underground work environment, be used for the leading temporary lining of driving face, beat and annotate anchor pole, anchor cable, set up the safe and efficient speedy drivage of i iron capplce realization comprehensive mechanization fast.
It is on probation to carry out the airborne temporary support device of boom-type roadheader since part producing mine in 2010 (Xishan coal electricity group company mine duerping, malanite, town Cheng Dikuang, Huozhou coal electricity dry river ore deposit etc.), realized mechanization temporary lining, eliminated suspension ring (U type card) string beam and pillar and added two kinds of artificial support forms of crossbeam.But there is following problem in the airborne temporary support device of development machine: (1) this device has only 1.5 tons to top board maximum support power, only plays the top effect of protecting under the good situation of geological conditions.(2) if when the big fragmentation of roof pressure, scaling or geological conditions are changeable, this device is inoperative.(3) this device is assemblied in and blocks driver's sight line on the development machine cantilever and the development machine front lamp disturbs normal cut operation.This device can not overturn smoothly and open withdrawal when (4) head-room was lower than 3.0 meters, head-room during greater than 4.0 meters this device can not use.(5) airborne front-probe support device protects that top area is little to have only 2.5 * 2.5 square metres.(6) during airborne leading temporary lining, can only beat and annotate the top anchor pole that side is helped in tunnel two, the top anchor pole at other position has only machine-carried forepoling device to regain and can beat notes.(7) using airborne temporary support device to carry out supporting operation operation restriction drivage efficiency improves.
Summary of the invention
The advanced stand device operating rate is slow in order to solve in the existing tunnel speedy drivage for the utility model, narrow application range, can not beat the problem of annotating anchor pole fast, provides a kind of roadway to dig the advance support integration unit soon.
The utility model is to adopt following technical scheme to realize: roadway is dug the advance support integration unit soon, it is characterized in that: comprise two slide rails that are set up in parallel, every one slide rail is provided with inner orbit groove, two rail grooves side by side of outside track groove; Portal trestle I, portal trestle II, three door shaped stents of portal trestle III have been arranged in juxtaposition on the slide rail from front to back, each portal trestle comprises two carrier bases, be fixed with a slide block that is enclosed within on the slide rail outside track groove on each carrier base, each inserts an intrinsic hydraulic prop upper and lower surface of each carrier base, is connected with crossbeam between two hydraulic prop tops of carrier base top; The slide rail front end is fixed with anchor pole and beats the notes support, anchor pole is beaten the notes support and is comprised two rail chair I that are enclosed within respectively on the slide rail inner orbit groove, two rail chair I inboards are vertically fixed a hydraulic jack respectively, be connected with anchor pole between two hydraulic jack tops and beat the notes crossbeam, anchor pole is beaten to annotate on the crossbeam and is laid with some anchor pole head installation chassis; Be horizontally disposed with some forestopes on the crossbeam of portal trestle I, be with on the slide rail inner orbit groove and the fixing rail chair II of the slide block of portal trestle III, be connected with the promotion hydraulic jack between rail chair I and the rail chair II, be releasable connection between the slide block of rail chair I and portal trestle I.The upper and lower surface of carrier base is inserted the mode that solid-liquid is pressed pillar, the fixing mode of slide block on carrier base, the rail chair II, slide block, rail chair I, rail chair II are enclosed within the mode of the releasable connection between the slide block of mode, rail chair I and portal trestle I on the slide rail, and these all are that those skilled in the art expect easily and realize.The definition slide rail is fixed with anchor pole, and to beat an end of annotating support be front end, defines each parts and part between back two slide rails is installed for inboard.Roadway is dug after advance support integration unit assembling finishes soon, preparation comprises steel band laterally is placed on the portal trestle I forestope by the array pitch of operating regulation regulation requirement, steel mesh reinforcement is placed on the steel band, spring jackscrew pin on the forestope blocks it and is tight with 12# iron wire bundle group, enough 1.6 to 3.2 meters of driving machine cut, cutterhead is fallen, and with development machine and cutting head locking, roadway is dug the advance support integration unit soon and is prepared to start working.
