Embodiment Construction
[0009] Jib cranes in inverted arch block transport systems of shield machines, such as figure 1 , figure 2 and image 3 As shown, it includes a support frame 1, an upper hinge seat 2 is arranged on the upper part of the side of the support frame 1, a lower hinge seat 3 is arranged on the lower side of the support frame 1, and the upper hinge seat 2 is connected to the turning seat 6, and the upper end of the turning seat 6 is hinged with the upper The seat 2 is hinged, and the lower end of the turning seat 6 is equipped with an electric push rod 11. The shell of the electric push rod 11 is hingedly installed on the turning seat 6. The end of the rod of the electric push rod 11 is hinged to the lower hinge seat 3, and the electric push rod 11. It is fixed in a hinged way, which not only maintains the flexibility of the operation process, but also avoids the disconnection phenomenon of contact fit, and further improves the safety performance. Horizontal swing arm 7 is install...

A jib crane in a shield tunneling machine inverted-arch block conveying system comprises a support. An upper hinged base and a lower hinged base are arranged on the side of the support. The upper hinged base is connected with a turning base. The upper end of the turning base is hinged to the upper hinged base. The lower end of the turning base is provided with an electric pushing rod. The outer shell of the electric pushing rod is hinged to the turning base. The end of a rod of the electric pushing rod is hinged to the lower hinged base. A jib is arranged on the turning base. A sliding trolley is hung on the jib. A sliding wheel of the sliding trolley is matched with the jib. An electric hoist is fixedly arranged on the bottom of the sliding trolley. The jib crane is directly inserted into a tunnel, inverted-arch blocks are lifted through the electric hoist, the inverted-arch blocks are conveyed through the sliding trolley along the jib, operation is easy, space is small, using is flexible, the jib crane can be used in a small tunnel environment conveniently, in a tunnel with a gradient, by stretching of the electric pushing rod, the jig is kept horizontal, so that the fact that the sliding trolley moves horizontally is kept, balanced stress of parts is kept, the problem that the sliding trolley slides along an oblique track is avoided, and accordingly the safety of a using process is improved.
Description
technical field [0001] The invention relates to an auxiliary invert block transport device for a shield machine trolley, in particular to a jib crane in the invert block transport system of a shield machine. Background technique [0002] During the tunnel shielding process, the inverted arch blocks are hoisted and transported by cranes. The space in the tunnel is narrow, and the operation of ordinary large-scale transportation equipment is limited, so it is not suitable for tunnel construction. The environment in the tunnel is complex, and some tunnels have slopes. The mechanical arm of the ordinary crane is in a tilted transportation state. The equipment walking on the mechanical arm is unbalanced and wears a lot. In a balanced stress state, failures are prone to occur, and there are hidden dangers in construction. Contents of the invention [0003] In order to solve the above problems, the object of the present invention is to provide a jib crane in the invert block t...
