Detailed Description
The following describes embodiments of the present invention in further detail with reference to the accompanying drawings.
The gantry shearing machine can be applied to the field of concrete beam recycling, and as shown in fig. 1, is an overall structural schematic diagram of a steel bar recycling system in a concrete beam, and comprises a material conveying table 2, a crushing machine 3, a rolling crusher 4, a waste output machine 5, a main steel bar shearing machine 6 and a main steel bar collecting machine 7.
The gantry shearing machine is a main steel bar shearing machine 6, and main steel bars with cleaned concrete blocks and stirrups are sheared as required; as shown in fig. 2, the main rebar shearing machine 6 includes a feed port 61, a shearing driving device 62, an upper blade holder 63, an upper blade 64, a lower blade holder 65, a lower blade 66, and a stripper plate 67.
The feed inlet 61 is located at the feed end of the main steel bar shearing machine 6, the feed inlet 61 is conical, the opening of the feed end is large, and dispersed steel bars are concentrated by the conical feed inlet 61 and then input to a shearing work position.
The cutting driving device 62 is vertically arranged and can be driven by a hydraulic cylinder; the piston rod of the shearing driving device 62 is connected with an upper cutter holder 63, and the tail end of the upper cutter holder is fixed with an upper blade 64; correspondingly, a lower tool apron 65 is arranged below the shearing driving device 62, a lower blade 66 is fixed on the lower tool apron 65, the upper blade 64 is driven by the shearing driving device 62 and the upper tool apron 63 to move towards the lower blade 66, the upper blade 64 and the lower blade 66 shear to cut off the main steel bars, and specifically, the shearing driving device 62 can act according to the required length of the main steel bars, so that the steel bars with the required length are obtained; during shearing, portions of the rebar slivers, particularly the stirrups that have been sheared off but remain on the main rebar, may fall further and slide out through the stripper plate 67 into a waste collection pit.
