Description
Technical field
The invention belongs to underground coal mine working faces to withdraw technical field of construction, and in particular to a kind of to be somebody's turn to do from shifting crossbeam and application
Construction technology is withdrawn from the fully-mechanized mining working for moving crossbeam.
Background technology
The dismounting of fully-mechanized mining working equipment, it is most crucial most dangerous in and projects particularly important to the supporting of top plate
Engineering, not only support material amount is using big, and construct threaten it is big.By improvement and innovation for many years, having formd makes
With one or two cover frame auxiliary shoring top plates, the technique of striking.But either one or two cover frames
Using all mine timber supporting is used without solving the problems, such as to reduce, so as to just be carried without reducing worker, use the process of mine timber, duty
Work labor intensity is still very big, and supporting mine timber security threat is still very big.In addition, of the prior art withdraw young of construction technology
Winch can be relied on to move cover frame, winch layout difficulty is larger, and there are many security risks, and construction efficiency is low.
The content of the invention
The object of the present invention is to provide it is a kind of can improve working face withdraw construction efficiency and security from move crossbeam and
The fully-mechanized mining working that mine timber uses can be reduced and withdraw construction technology.
To achieve the above object, the present invention provides following technical schemes：
It is a kind of to move crossbeam certainly for what underground hydraulic support frame was removed, including cross-beam body, along length on the cross-beam body
Direction is arranged at intervals at least three hinged-supports, and the homonymy of each hinged-support towards cross-beam body is set.
Preferably, each hinged-support forms adjustable be fixedly connected along cross-beam body length direction with cross-beam body.
Preferably, each hinged-support is corresponded on the cross-beam body equipped with multiple bolts hole, each bolt hole is along cross-beam body
Length direction uniform intervals set, the hinged-support include a connecting portion, the connecting portion be equipped at least two bolts hole
It is engaged with the bolt hole on cross-beam body.
Preferably, one end of the cross-beam body is additionally provided with a hydraulic cylinder, the cylinder body of the hydraulic cylinder and cross-beam body
It is hinged between end by cross hinged-support.
The present invention also provides construction technology is withdrawn from the fully-mechanized mining working for moving crossbeam described in a kind of application, including walking as follows
Suddenly：
Step 1：The formation of cover frame, each hydraulic support in working face are named successively from one end of working face to the other end
For No. 1 frame, No. 2 frame ... n framves, mode is removed by after No. 1-No. 3 framves dismounting of working face according to conventional stent, timely entrucking is beaten
It transports, tear frame winch open using working face removes frame nest by No. 6 framves, monomer is coordinated to be adjusted to No. 6 framves parallel with coal wall, uses monomer
One end, which is supported on, does not tear open on stent, and one end is supported on No. 6 frame front end pedestals, and No. 6 framves are supported to frame head and No. 7 frame side guard plates and are put down
Neat position is used as the coal side cover frame of side 1, and cover frame frame head is towards holder orientation to be removed, in time by No. 1 cover frame liter
It rises and is pushed against with top plate；No. 5 framves, No. 4 framves are removed successively according to the method described above, are adjusted to, stent frame head and No. 7 framves parallel with coal wall
Side guard plate is concordant, is used respectively as No. 2, No. 3 cover frames；
Step 2：It, in time will be from moving crossbeam installation after three cover frames are all in place, and be linked with three cover frames passage
Head is connected；
Step 3：Remove remaining stent successively using frame winch is torn open, often remove a stent No. 3 cover frames and old man it
Between move towards marguise using road plate in passage, two column of a beam, No. 1, after No. 2 cover frames passage using no mine timber supporting；Often remove
One stent, three cover frames, which are drawn forward, moves a step pitch；According to the order of No. 3, No. 2, No. 1 cover frames, drawing shifting is carried out successively,
Specifically displacement process is：Environment before cleaning cover frame by 3 cover frame feed flow, passage head is stretched out, is pushed away using two cover frames
Head is moved as fulcrum, after frame drops in the 3rd cover frame column, the 3rd cover frame passage hydraulic cylinder is received, is allowed to move certainly forward, three
After platform cover frame moves forward a step pitch, frame is risen in time and connects strength with top plate；As procedure described above, cover frame is drawn and moves 2 steps
Width away from i.e. two stents；
Step 4：After last three support removings of working face, lift canopy mouth beats grillage branch in stent frame nest and on working face
Protect top plate；
Step 5：Cover frame is removed, will be removed first from crossbeam is moved, three are carried out according to No. 3, No. 2, the order of No. 1 after dismounting
The dismounting of platform cover frame；A cover frame is often removed, crib protection is played in the cover frame frame nest.
Preferably, in step 1, if the use of working face channel side is set up on stent frame head moves towards H-shaped steel supporting, 2
Number, No. 3 cover frame frame heads against stent to be torn open, No. 1 cover frame is No. 2 advanced, the width of No. 3 cover frames i.e. one stent of one step pitch
Degree.
Preferably, in step 1, after three cover frames are in place, cover frame side guard plate is opened, and abuts against three cover frames
Together.
Preferably, with the dismounting of No. 1-No. 3 stents, grillage is beaten with lift canopy mouth under channel side in stent frame nest in time and added
Strong roof timbering；During three cover frame formation, old man side often removes a frame cover frame and plays crib protection in frame nest in time, until
Three cover frames are completely formed；Channel side takes off cladding along mountain marguise, four column of a beam, no less than two rows, until three are covered using 3m
Retaining frame is completely formed.
Preferably, in step 1, No. 1, after No. 2 cover frames are formed, before No. 3 cover frames are not formed, get column ready and strengthen top
Slab supporting.
Preferably, if working face passage is I-steel marguise supporting in steps of 5, before removing last cover frame
Must by marguise supporting it is secured after just last dismountable cover frame.
The technical effects of the invention are that：The present invention aids in three shield supports to push ahead using crossbeam is moved certainly, saves
Most pulling winch has been removed, has improved propulsive efficiency, working face construction environment has been simplified, improves security.In addition, this
The construction technology that invention provides reduces the use of mine timber, reduces the cost of construction.
