Support tunnel lateral wall.
The working principle of gib equipment of the invention are as follows: gib equipment needs to straddle above development machine, and
Entire development machine is covered, after development machine completes the headwork of a distance, causes the unsupported back span of back to become larger, makes lane
Road top plate becomes unstable, is then easy to produce the accidents such as roof fall at this time, needs to control gib equipment at this time and moves forward to
Below the back of supporting, support force first is provided by top beam component 6 and is then passed through to support unstable back
Collateral support component 9 carries out supporting to tunnel lateral wall, to prevent wall caving, guarantees the safety of lower section development machine and personnel.
The application method of the roadway head gib equipment, when back is unstable, such as Fig. 6 institute
Show, using wriggly walking mode, includes the following steps:
Step 1: first dropping to extreme lower position for the top beam component 6 at the top of the gate frame of I type bracket 15, then by I type branch
The collateral support component 9 of 5 on both sides of the middle of gate frame of frame 1 is adjusted to retracted state, finally by 5 bottom of gate frame of I type bracket 1
The leg assembly 7 in portion is adjusted to lifting status, and I type bracket 1 is in vacant state at this time；
Step 2: the passage component 8 between control I type bracket 1 and II type bracket 2 forward extends out, and makes I type bracket 1 forward
A mobile step pitch；
Step 3: the leg assembly 7 of 5 bottom of gate frame of I type bracket 1 is first adjusted to stretching state, makes supporting leg group
Part 7 supports roadway floor；The collateral support component 9 of 5 on both sides of the middle of gate frame of I type bracket 1 is adjusted to unfolded state again, is made
Collateral 9 supported laneway lateral wall of support component；Finally it is adjusted to the top beam component 6 at 5 top of the gate frame of I type bracket 1 to rise shape
State makes 6 supported laneway top plate of top beam component；
Step 4: referring to the moving process of I type bracket 1, control II type bracket 2 moves forward a step pitch；
Step 5: it referring to the moving process of I type bracket 1, controls first type III bracket 3 and moves forward a step pitch；
Step 6: it referring to the moving process of I type bracket 1, controls first IV type bracket 4 and moves forward a step pitch；
Step 7: referring to the moving process of I type bracket 1, subsequent type III bracket 3 and IV type bracket 4 are controlled respectively forwardly
A mobile step pitch, until gib equipment integrally moves forward a step pitch.
When back is unstable, then gib equipment is needed to be capable of providing biggish support force, while will also be
It moves and guarantees the constant of support force during frame as far as possible, since gib equipment uses the advancing velocity of wriggly walking mode
It is relatively slow, each only mobile bracket, therefore the influence to back is minimum, so using wriggling when back is unstable
Walking manner is the most suitable, and supporting effect is most ideal.
The application method of the roadway head gib equipment, when roadway surrounding rock is more stable, such as Fig. 7 institute
Show, using walking manner of alternately taking a step, includes the following steps:
Step 1: by I type bracket 1 labeled as 1. number bracket, being labeled as 2. number bracket for II type bracket 2, and so on, it will
4 carry out sequence label of subsequent all type III brackets 3 and IV type bracket；
Step 2: first dropping to extreme lower position for the top beam component 6 at 5 top of the gate frame of all odd numbered brackets,
The collateral support component 9 of 5 on both sides of the middle of gate frame of all odd numbered brackets is adjusted to retracted state again, will finally be owned
The leg assembly 7 of 5 bottom of gate frame of odd numbered bracket is adjusted to lifting status, and all odd numbered brackets are at this time
Vacant state；
Step 3: the passage component 8 for controlling all odd numbered brackets rear forward extends out, and makes all odd numbered brackets
Move forward a step pitch；
Step 4: being first adjusted to stretching state for the leg assembly 7 of 5 bottom of gate frame of all odd numbered brackets,
Leg assembly 7 is set to support roadway floor；Again by the collateral support component 9 of 5 on both sides of the middle of gate frame of all odd numbered brackets
It is adjusted to unfolded state, makes collateral 9 supported laneway lateral wall of support component；Finally the gate frame 5 of all odd numbered brackets is pushed up
The top beam component 6 in portion is adjusted to raised configuration, makes 6 supported laneway top plate of top beam component；
Step 5: referring to the moving process of odd numbered bracket, all even-numbered brackets is controlled and move forward a step
Away from until gib equipment integrally moves forward a step pitch.
When roadway surrounding rock is more stable, influence of the gib equipment shifting frame process to back is smaller, then preferentially adopts
With walking manner of taking a step is replaced, since gib equipment only needs two circulation actions using walking manner of alternately taking a step
To previous step pitch, the speed of travel is fast, and work efficiency is high.In actual operation, it can be adjusted at any time according to roadway surrounding rock situation
The walking manner and step pitch of gib equipment can maximize working efficiency under the premise of guaranteeing supporting effect in this way.
The scope of patent protection that scheme in embodiment is not intended to limit the invention, it is all without departing from carried out by the present invention etc.
Effect implements or change, is both contained in the scope of the patents of this case.
