The working principle is as follows:
first, state 1 (determining the center position of the working position):
in this state, the three-position switching oil cylinder has a long stroke S1 of 150mm and is fully extended, a short stroke S2 of 95mm and is fully retracted, and the installation distance of the oil cylinder is 695 mm.
At this time, we marked the operation center of the grouting push beam as the operation station center of the three push beams (the connection line between the operation station center and the rotation center of the swing frame forms an included angle of 158 ° with the vertical direction).
Second, state 2 (adjusting the center of the tunneling propelling beam to the center of the operation working position):
in the state, the long stroke S1 of the three-position switching oil cylinder and the short stroke S2 of the three-position switching oil cylinder are all retracted when being 150mm and 95mm, and the installation distance of the oil cylinder is 545 mm.
At this time, the center of the tunneling propelling beam is close to the operation center calibrated as fig. 2, and the connecting line of the center of the tunneling propelling beam and the rotation center of the deflection frame forms an included angle of 161 degrees with the vertical direction and deviates from the calibrated operation center by 3 degrees. Therefore, the excavation position adjusting bolt is required to be adjusted to limit the retraction distance of the long stroke, so that the included angle formed by the connecting line of the center of the excavation propelling beam and the rotation center of the deflection frame and the vertical direction is 158 degrees, and the aim of enabling the center of the excavation propelling beam to be coincident with the calibrated operation position center can be achieved.
Thirdly, state 3 (adjusting the center of the anchor rod propelling beam to the center of the operation working position):
in the state, the long stroke S1 of the three-position switching oil cylinder and the short stroke S2 of the three-position switching oil cylinder all extend out when being equal to 150mm and 95mm, and the installation distance of the oil cylinder is 790 mm.
At the moment, the center of the anchor rod propelling beam is close to the operation working center calibrated in the figure 3, and the included angle formed by the connecting line of the center of the anchor rod propelling beam and the rotation center of the deflection frame and the vertical direction is 155 degrees and deviates from the calibrated operation working center by 3 degrees. Therefore, the bolt for adjusting the anchor rod position is required to be adjusted to limit the extending distance of the short stroke, so that the included angle formed by the connecting line of the center of the anchor rod propelling beam and the rotation center of the deflection frame and the vertical direction is 158 degrees, and the aim of enabling the center of the anchor rod propelling beam to coincide with the center of the calibrated operation working position can be fulfilled.
By combining the conditions, the central position of the grouting push beam when the long stroke of the three-station switching oil cylinder is completely extended is determined. And when the three-station switching oil cylinder is adjusted to be in other states, the centers of the tunneling push beam and the anchor rod push beam coincide with the determined center position of the grouting push beam, so that the three push beams can be accurately positioned during three-station switching.
