The pitching motion of arm in being realized by middle arm pitching oil cylinder.
Middle arm front end is provided with forearm, and forearm is hinged by forearm pitching oil cylinder and middle arm, can by forearm pitching oil cylinder
Realize the pitching motion of forearm.
Further, the drive cylinder of large arm quadric chain of the present invention, its installation form are not limited only to this, it is not
It can only be arranged on inside quadric chain, can also be arranged on outside quadric chain.
Further, the present invention realizes that the recycling of arm support folds by large arm around bearing revolution, while can be by middle arm, small
Arm and large arm front-end architecture are pushed to above three steps, realize normal work of the arm support on three steps.
Further, the present invention can not only meet full section of tunnel（One step）With the needs of two step piercing techniques, and
And by setting different equipment interfaces on forearm, it can be achieved that carrying out different construction operations on three steps, such as
The operations such as arching operation, rock drilling machine operation, aerial work platform.

Embodiment
An application example of the present invention on constructing tunnel trolley is given below.
As Figure 4-Figure 6, constructing tunnel trolley of the present invention with arm support include turntable 1, bearing 2, large arm 3, middle arm 4,
Middle arm pitching oil cylinder 5, forearm 6, forearm pitching oil cylinder 7.
Turntable 1 is arranged on the lowermost end of whole arm support, for being connected with corresponding engineering truck, and is provided for whole arm support
Revolution acts.As shown in Fig. 7 arrows.
Bearing 2 is fixed at the top of turntable 1.
Large arm 3 includes the first bar 31, the second bar 32, drive cylinder 33 and tripod 34, wherein the first bar 31 and the second bar
32 one end is hingedly connected to 2 both ends of bearing, and the other end of the first bar 31 and the second bar 32, which is respectively articulated with, is fixed on tripod 34
On two angles of bottom, such bearing 2, the first bar 31, the second bar 32, tripod 34 are connected to become one group of quadric chain, and
The equal two-by-two to edge lengths of quadric chain is configured to one group of parallelogram mechanism.33 one end of drive cylinder is articulated with bearing
