At this time, the gripper arch assembly receives the acting force F1 of the hinge pin at the point G, O of self gravity, the acting force F2 of the whole body of the arch and the ground contact point, the floating cylinder 12 does not stretch and move at this time, and can be regarded as a fixed telescopic rod, so that the floating cylinder 12 has no effect on the assembly. And (3) taking the point O as an origin, establishing a rectangular coordinate system, wherein the distance from the gravity G to the origin O is a, and therefore, the moment generated by the gravity on the point O is M=G×a. When the manipulator slowly lifts up the arch, because moment M's effect, the cambered surface that the arch is located is greater and greater with the angle on ground for the D point has contact with ground all the time, and when the manipulator lifts to vertical position, the assembly of tongs 5 and arch also can be put forward vertical position, and slightly remove vehicle or flexible arm and remove the arch to predetermined position again can begin the concatenation.
When the manipulator lifts the steel arch, the oil cylinder only serves as a telescopic rod, and the steel arch can rotate around the hinged pin shafts of the gripper 5 and the outer extension cylinder 6 together with the gripper 5 by means of self gravity until the cambered surface where the arch is located is perpendicular to the ground.
In addition to the tunnel steel arch installing manipulator and the manipulator working platform provided in the above embodiments, the structure of each other portion should refer to the prior art, and will not be described herein.
In the present specification, each embodiment is described in a progressive manner, and each embodiment is mainly described in a different point from other embodiments, and identical and similar parts between the embodiments are all enough to refer to each other.
