The rapid supporting equipment for the excavation roadway according to claim 1, characterized in that: the second cradle unit includes: the support frame comprises a second support frame base, a second support frame support and a second support frame top beam, wherein one end of the second support frame support is hinged to the second support frame base, and the other end of the second support frame support is hinged to the second support frame top beam.
9. The rapid supporting equipment for the excavation roadway according to claim 8, characterized in that: the second cradle unit further comprises:
one end of the second support frame auxiliary support is hinged with the second support frame base, and the other end of the second support frame auxiliary support is hinged with the side wall of the second support frame support;
the base crosshead is hinged with the second support frame base and the connecting mechanism;
and the anti-skid protruding mechanism is arranged above the top beam of the second support frame.
10. The use method of the tunneling roadway rapid support equipment based on any one of claims 1-9 comprises the following steps:
the method comprises the following steps: preparing a tunneling roadway rapid supporting device, standing a worker on a base of a second support frame to start the tunneling roadway rapid supporting device, realizing sliding between a first support frame unit and the second support frame unit by controlling a connecting mechanism between the first support frame unit and the second support frame unit, and then operating the second support frame to support and lift, wherein the second support frame unit plays a supporting role at the moment;
step two: after the second support frame unit is moved, a worker places auxiliary materials on the paving bracket, the worker enables the vertical chain to operate by shaking the hand wheel to drive the transmission shaft, the transmission shaft drives the horizontal transportation chain to push the paving bracket from back to front, the hand wheel locks when the paving bracket reaches the flexible front detection support mechanism, then the worker places the net piece and the steel beam on the paving bracket, the worker enables the vertical chain to operate by shaking the hand wheel to drive the transmission shaft, the transmission shaft drives the horizontal transportation chain to push the paving bracket from front to back, the hand wheel locks when the position of the flexible front detection support mechanism moves to the position in front of the rear material support frame, and the net piece covers the steel beam;
step three: the worker controls the connecting mechanism between the first support frame unit and the second support frame unit to realize the forward movement of the first support frame unit, and controls the first support frame unit to guide, support and lift to realize the lifting of the first support frame unit;
step four: a worker operates the end face protection mechanism to enable the side protection plate to be supported on the end face, and then the multi-degree-of-freedom drilling machine transfer mechanism is started to enable the anchor rod drilling machine set to translate forwards to a position suitable for anchoring construction;
step five: a worker stands beside the anchor rod drilling unit, uses the control mechanism to adjust the transverse position of the anchor rod drilling unit to enable the anchor rod drilling unit to be in a drilling hole position required by a roadway, operates the anchor rod drilling unit by the worker to withdraw an uninterference area after anchoring is finished, and then withdraws the end face protection mechanism;
step six: the worker controls through controlling the coupling mechanism between first support frame unit and the second support frame unit, realizes that the second support frame unit moves forward, then operates second support frame support and descends, accomplishes the use of this equipment, waits to strut when the anchor construction need next time and repeat above-mentioned step can.
