Description
The invention belongs to underground coal mine full-mechanized roadway piercing technique technologies, more particularly to anchor combined based on robotization pick branch
The full-mechanized roadway piercing technique of unit.
Background technique
In recent years, although China's coal roadway tunneling technology is constantly progressive, the degree of automation is not still high, and drivage efficiency remains unchanged
It is very low.Comprehensive pick method is a kind of advanced tunnelling technology developed rapidly in nearly 20~30 years, and wherein development machine collection is cut
Cut, load and transport, the functions such as depositing dust are in one, have high production efficiency, driving speed it is fast, it is adaptable, transfer it is flexible
Advantage substantially improves working condition, therefore is widely used in the tunneling construction of major coal mine.But the development machine of the prior art
Mostly pilot steering and manipulation, causes that driver's large labor intensity, the visual field is narrow, the working environment of workers is severe, labor productivity is low
The problems such as, and construction quality, construction safety are largely dependent upon human factor, the number of casualties of underground is still more.
Currently, the tunneling construction process of traditional full-mechanized roadway generally comprise transfer slotting, cutting coal seam, coal breakage transporting coal,
Gib, drilling lapping, permanent anchorage amount to six process portions.In traditional full-mechanized roadway piercing technique, driving, interim branch
Shield, permanent anchorage operation are chained job, and progress and mostly manual operation cannot be generally cooperateed between each process, therefore tunnels effect
Rate is very low, the problems such as pick branch serious disproportion, Linking up digging is nervous often occurs, and the degree of automation is very low, worker's work
Bad environments, there is biggish construction risk, and accident rate is higher.
The form of laneway temporary support mainly has six kinds at present: individual prop+bolumn cap, individual prop+hinged girder+plate-girder,
The long girder steel forestope of suspension type, console mode move falsework, capplce suspension type automatic shifting stand, piggyback temporary support certainly.First three
Support pattern have the shortcomings that supporting not in time, control top ability it is weak, expend working hour it is long, the degree of automation is low, supporting effect is poor, fall
Although ground formula is higher from shifting falsework and capplce suspension type automatic shifting stand the degree of automation, during anchor net laying is set often
Also manpower is needed to assist, can not also accomplish full-automatic operation in bracket movement and Bracing Process, also manpower be needed to assist, and
The bracket that support is completed is the supporting of mechanization, can not perceive the reliability of supporting.
The researcher of Shanxi Lu'an Environmental Protection Energy Development Co., Ltd. Zhangcun Coal proposes that a kind of pick anchor is continuous certainly
Dynamicization fast digging technique (patent No. CN103899319A), the technique is using face end support as gib equipment, and end
The usual geometric dimension of bracket is larger, and frame body is heavy and Forward is difficult, causes the time used in gib longer, efficiency is lower.Together
When the technique permanent support is divided into meet head on supporting and rear supporting two parts using face end support as boundary, using jumbolter device into
Row supporting operation, wherein although rear supporting can tunnel concurrent job with development machine, the driving of meet head on supporting and development machine exists
Time can conflict, and cannot carry out simultaneously, so the concurrent job of driving and permanent support can not be realized truly.This
Outside, driving and support apparatus the degree of automation are lower in the technique, and drivage efficiency is not high, and the working environment that construction personnel faces is very
It is dangerous.
For disadvantages mentioned above, the full-mechanized roadway piercing technique based on the anchor combined unit of robotization pick branch, the technique are proposed
Middle driving, permanent anchorage, the big process of gib three are intersected concurrent job using two one continuous modes of interruption, are adopted simultaneously
With full-automatic driving and support apparatus, so that drivage efficiency promotes about 2.5 times, and the safety of construction is improved.This
Outside, it is independently tunneled using unmanned intelligent independent formula development machine, is carried out using the autonomous gib hydraulic support of automatic moving type
Gib operation carries out permanent anchorage operation using robotization drilling anchor vehicle, can really realize driving and permanent support and
Row operation.New anchor net laying can be located at the top of the self-advancing hydraulic support on transporting bracket vehicle by robotization drilling anchor vehicle automatically
Portion realizes the full-automatic operation for being laid with cradle top anchor net, while the self-advancing hydraulic support that support is completed can be pushed up by it
The reliability of the sensing device automatic sensing supporting in portion, substantially increases the safety and reliability of gib.
Summary of the invention
The purpose of the present invention is overcome in the prior art drivage efficiency is low, the degree of automation is low, job security is low to lack
Point, the present invention provides a kind of full-mechanized roadway piercing techniques based on the anchor combined unit of robotization pick branch.
