A kind of production autoclaved aerated building block dust-proof cutting car of U-shaped frame
The invention belongs to construction machinery equipment production technical field, particularly relate to the dust-proof cutting car of a kind of production U-shaped frame of autoclaved aerated building block.
The cutting car of existing air-entrained concrete building block production line cutting unit important component part is main mainly with horizontal frame formula structure greatly, walking track greatly mainly with one-sided V-type track or trapezoidal track as track travel benchmark, by side plate and column bilateral draw-in groove location after the base substrate demoulding.Cutting car vehicle body general frame is higher than cutting orbit plane, and wheel and rail contact position cannot add guard assembly, easily because waste material or useless splashing of starching cause the damage of track and transmission component in the process of cutting operation, affects cutting accuracy and service life.No matter and existing cutting car structure is with chain traction, the transmission mechanism of rack-and-pinion combination all cannot avoid the impact because materials and parts splash on track and transmission system generation completely, easily goes wrong, causes the increase of after cost.Gear teeth fan mechanism is reliably relatively stable, but mechanism is bottom car, easily enters silt stone, damage gear above gear, and the lubrication of gear is also difficult to accomplish, and rack-and-pinion manufacturing cost is higher.
Summary of the invention
The object of the invention is the protective that exists for the cutting car of prior art not enough, maintenance cost is high, keeps in repair loaded down with trivial details, the technical problem that the life-span is short, provides a kind of and new-type certainly protects cutting car, to overcome the deficiencies in the prior art.
The object of the invention is to be achieved through the following technical solutions, the dust-proof cutting car of this U-shaped frame
Comprise cutting car and protective plate, described cutting car comprises U-shaped frame and support column, described U-shaped frame comprises a crossbeam and is fixed on the connecting plate at crossbeam two ends, the connecting plate at described crossbeam two ends is fixed with vehicle wheel component, described support column is fixedly connected with U-shaped frame crossbeam, described support column is provided with alignment pin, and described alignment pin adopts self-locking thread to be fixedly connected with support column upper panel, and using nuts locking regulates; Track adopts bilateral plate rail mounted track directive wheel to fix; Described protective plate comprises upper guard board and lower backplate, and described upper guard board is arranged at vehicle wheel component top, is fixed on foundation framework, and described lower backplate is fixed on bottom U-shaped frame, by upper guard board and lower backplate by whole piece track and cutting car wheel assembly completely closed.
Described support column and U-shaped frame crossbeam adopt and are welded and fixed.
Described vehicle wheel component is fastenedly connected by bolt group and connecting plate.
During work, in the process of cutting car walking, waste material gear is dropped down onto inside track by upper guard board by side cutting waste material, and the useless slurry gear that waste material drops and splashes by lower backplate is outside track, ensure that the clean of track.Be ensure that the walking precision of cutting car by directive wheel, while the service life of improving whole piece line of cut, decrease the unnecessary loss because plant maintenance causes with damage.
Beneficial effect of the present invention: owing to being provided with upper guard board and lower backplate on the top of track and side, can effectively stop the waste material produced during cutting to drop on track, ensure that the clean of track, improves the service life of track; Meanwhile, because overall structure adopts U-shaped framework, while wheel and track obtain protecting, reduce the position of centre of gravity of whole cutting car, be conducive to improving cutting accuracy.
