9. The reinforcing device for the working surface of the weak and broken surrounding rock based on the full-face construction is characterized in that the axis of the output shaft of the speed reducer (312) and the axis of the arc-shaped frame (100) are collinear.
10. The use method of the reinforcing device for the working surface of the weak and broken surrounding rock based on full-face construction is carried out by using the reinforcing device for the working surface of the weak and broken surrounding rock based on full-face construction as claimed in any one of claims 1 to 9, and is characterized by comprising the following steps of:
the method comprises the following steps: firstly, pushing an arc-shaped frame in a tunnel, wherein the arc-shaped frame moves back and forth in the tunnel under the guidance of a linear rail to move the arc-shaped frame to a preset position;
step two: then a second servo motor is started, the second servo motor drives a speed reducer to work, the speed reducer reduces rotation, the speed reducer drives a support frame to rotate around the axis of an output shaft of the speed reducer through a connecting block, and the support frame rotates around the axis of the arc-shaped frame because the axis of the output shaft of the speed reducer is collinear with the axis of the arc-shaped frame, so that the support frame is ensured to be vertical to the arc-shaped frame all the time;
step three: the support frame stops working of the second servo motor after rotating to a preset angle, then the anchor rod is fixed on the connecting seat, then a third servo motor is started, the third servo motor drives the first chain wheel to rotate, the first chain wheel rotates to drive the second chain wheels on two sides to rotate through the chain, the second chain wheel rotates to drive the lead screw to rotate, the rotation of the lead screw drives the transmission nut to move forwards along the lead screw, the transmission nut drives the first mounting frame to move forwards along the lead screw, the first mounting frame drives the anchor rod to move forwards, and the anchor rod sequentially penetrates through the avoiding holes in the arc-shaped slide block and the avoiding grooves in the arc-shaped frame until the front end of the anchor rod is contacted with the inner side of the tunnel;
step four: then, starting the first servo motor, driving the connecting seat to rotate by the first servo motor, driving the anchor rod to rotate by the connecting seat, and enabling the anchor rod to enter the tunnel to realize automatic driving;
step five: after the anchor rod is drilled, all the first servo motors and the second servo motors stop working, then the anchor rod is separated from the connecting seat, the anchor rod is left in the tunnel, then the third servo motor is started to rotate reversely, then the first mounting frame drives the connecting seat to move backwards to the initial position, then the third servo motor is stopped to work, then the second servo motor is started to enable the supporting frame to rotate by another angle, and the operation is carried out in a circulating mode.
