Relining manipulator crane span structure

Abstract

The invention discloses a relining manipulator crane span structure. The relining manipulator crane span structure comprises a stand, cantilever beams, a relining trolley, guard bars and side joint frames; the two cantilever beams are arranged in the middle of the stand in parallel; the relining trolley is arranged between the two cantilever beams in a sleeving mode; the guard bars are longitudinally arranged on the upper portions of the middles of the two cantilever beams; the two ends of the two cantilever beams are vertically provided with sleeve clamping bases; and the side joint frames are arranged below the two sleeve clamping bases. The relining manipulator crane span structure has the beneficial effects that a worker puts a lining plate on a lining conveying trolley by standing onthe cantilever beams to convey the lining plate, and when the worker stands on the cantilever beams, the worker leans on or holds extending bars of the guard bars, so that operation safety of the worker on the crane span structure is ensured; and hydraulic pumps below the two ends of the guard bars drive the extending bars to ascend or descend through hydraulic rods, so that the use height of theoverall guard bars is adjusted, it is ensured that workers of different heights can use the guard bars more comfortably and conveniently, and the use flexibility and safety are ensured.

Description

technical field [0001] The invention relates to a bridge structure, in particular to a bridge structure of a relining manipulator, and belongs to the technical field of bridge structure applications. Background technique [0002] The bridge structure is an indispensable component of the relining manipulator. The main function of the bridge structure is to accommodate the relining trolley. The lining plate is transported to the mill through the relining trolley, which is convenient for the staff to replace the lining plate in the mill. [0003] The existing manipulator bridge structure for relining still has many deficiencies in use. When the existing manipulator bridge structure for relining is used to transport the liner by the relining trolley, the liner is not stable enough to be moved and transported, and the liner is easy to shake Or fall off, and the friction damage between the liner and the components on the bridge structure is large, and the safety of the staff worki...
