5. a kind of pick branch anchor combined unit two sections of automatic laying methods of steel band of circulation, use pick described in claim 1 branch
Anchor combined unit two sections of steel band automatic laying devices of circulation, it is characterised in that include the following steps:
Step 1: two sections of steel bands of circulation to be laid are put into steel band feeding plummer from pick branch anchor combined unit top beam rear
On, two sections of steel bands of the circulation be can folded structure, the angle for recycling two arm rooms of two sections of steel bands is adjustable, recycles two at this time
Section steel band is in fully unfolded position, i.e. dog-ear is equal to 180 °；
Step 2: starting hydraulic motor drives chain rotation by drive sprocket, is moved folded steel band adapting table by chain
It moves immediately below steel band feeding plummer, folded steel band adapting table at this time is in fully unfolded position, i.e. dog-ear is equal to
At 180 °；
Step 3: the piston rod retraction of control steel band feeding expansion bracket driving hydraulic cylinder, so that steel band feeding expansion bracket integrally contracts
It is short, while gradually decrease the height of steel band feeding plummer, it is fallen in pair until recycling two sections of steel bands on steel band feeding plummer
On folding steel band adapting table；
Step 4: reverse starting hydraulic motor drives chain to rotate backward, by chain by folded steel band by drive sprocket
Adapting table is moved to right above folded steel band adapting table dog-ear adjustment shifting block, then controls the adjustment of folded steel band adapting table dog-ear
The piston rod of hydraulic cylinder bounces back, and makes folded steel band adapting table dog-ear adjustment shifting block that rotation occur, will be in and be fully deployed shape
The folded steel band adapting table switch of state is to setting dog-ear state, and folded steel band adapting table at this time is together with circulation two thereon
V-structure is presented in section steel band；Meanwhile the piston rod for controlling steel band feeding expansion bracket driving hydraulic cylinder is overhanging, makes steel band feeding
Plummer returns to initial position；
Step 5: continue reverse starting hydraulic motor, until folded steel band adapting table is moved to steel band feeding by chain
Right above plummer, while folded steel band adapting table acts against and generates change on folded steel band adapting table dog-ear reseting baffle
Shape, so that folding steel band adapting table is restored to fully unfolded position from V-type doubled state together with two sections of steel bands of circulation thereon；
Step 6: the piston rod retraction of control lifting slider pedestal driving hydraulic cylinder, so that lifting slider pedestal is slided along lifting
Block base rail moves up, until steel band feeding plummer jacks up two sections of steel bands of circulation on folded steel band adapting table；
Step 7: the piston rod of control steel band feeding expansion bracket driving hydraulic cylinder stretches out, so that steel band feeding plummer is moved to
The front of the anchor combined unit forestope of pick branch；
Step 8: the anchor combined downward rotation of unit forestope of first control pick branch, then the recession of steel band feeding plummer is controlled, make steel band
Two sections of steel bands of circulation on feeding plummer are located above the anchor combined unit forestope of pick branch, then the anchor combined unit of control pick branch
The upward rotation of forestope finally makes to recycle two sections of steel bands accurately into a pick branch anchor combined unit forestope upper surface to horizontality
Steel band card slot in；
Step 9: the piston rod retraction of control steel band feeding expansion bracket driving hydraulic cylinder, while controlling the driving of lifting slider pedestal
The piston rod of hydraulic cylinder is overhanging, and steel band feeding plummer is made to return to initial position, completes the automatic paving of two sections of steel bands of a circulation
If；
Step 10: as the anchor combined unit of pick branch constantly tunnels forward, step 1 is repeated to step 9, completes two sections of following cycle
The automatic laying of steel band；
Step 11: with the advance of the anchor combined unit of pick branch, when two sections of steel bands of the circulation formerly laid reach steel band feeding
When right above plummer, the piston rod for controlling steel band feeding expansion bracket driving hydraulic cylinder is overhanging, until steel band feeding plummer top
It leans against on back, enters two sections of steel bands of circulation on back in steel band feeding plummer；
Step 12: it after the anchor combined unit of pick branch moves forward, completely disengages the anchor combined unit top beam of pick branch and is taken by steel band
Material plummer acts against two sections of steel bands of the circulation on back, then controls steel band feeding plummer and moves down, makes to carry and follow
The steel band feeding plummer of two sections of steel bands of ring returns to initial position；
Step 13: step 2 is repeated to step 9, realizes that the circulation of two sections of steel bands of circulation is laid with automatically.
