Description
Technical field
The present invention relates to setting machine, relate in particular to a kind of electro-hydraulic servo cylinder setting machine.
Background technology
On brick and tile manufacturing line, after base substrate is by cutting moulding, must pile up on drying cart or kiln car according to certain mode, after what is said or talked about, sent into dry kiln or drying hole and carried out processed, enter again calcining kiln and carry out roasting, finished bricks after roasting is unloaded down from kiln car, and this yard of base, the process of unloading brick are the indispensable rings of brick field.In the past, most of brick field was the manual code of dependence base, unloaded brick by hand, but along with manufacturing fast development, setting machine starts to have replaced gradually manpower.
In recent years, building industry is more and more higher to the requirements for quality of brick, not only require the intensity of brick high, and presentation quality is also had to requirement, even the brick face of building inside also wishes not have the defects such as blackspot, this just requires to pile up base substrate square formation on kiln car can keep good ventilation when dry, roasting.And adopt along coding mode, be the good method that solves this difficult problem, setting machine, by marshalling equipment is adjusted, just can be realized the requirement along code, has so not only improved the quality of base substrate, and has accelerated the speed of burning till, and has reached the object that improves output.
In traditional setting machine lift structure design, conventionally adopt in two ways at present, a kind of is to add guide pillar guide pin bushing form with chain-type mechanical lifting or chain-type mechanical lifting, another kind is the form that hydraulic efficiency pressure system hydraulic actuating cylinder adds guide pillar guide pin bushing.The former is more mixed and disorderly in the process of lifting, and easily card touches, and lifting is unstable, and chain structure is easy to wear occurs the phenomenon of skidding, and service life is low, and operating accuracy is low; The latter is better in the stability promoting, but it is so inaccurate that appoint location, gap on base is stamped longitudinally between adobe is difficult to guarantee to be straight joint, adobe unbalance stress is easy to occur damaged, and enter like this after kiln and on the section of kiln, increased the resistance ventilating again, impact is ventilated, and sintering process also has a certain impact to the presentation quality of brick.
Summary of the invention
The technical assignment of technical matters to be solved by this invention and proposition is that prior art is improved, a kind of electro-hydraulic servo cylinder setting machine is provided, solving the positioning precision of piling up of setting machine in current technology, low to cause adobe to stack regularity poor, affects the problem of adobe sintering.
For solving above technical matters, technical scheme of the present invention is:
A kind of electro-hydraulic servo cylinder setting machine, comprise fixed frame, hitch, adobe holding device, servo dolly and electro-hydraulic servo cylinder lift system, it is characterized in that, described servo dolly crossbearer can move back and forth along the crossbeam of fixed frame on fixed frame, hitch is fixed on servo dolly bottom by tie bolt, adobe holding device is connected on hitch, described electro-hydraulic servo cylinder lift system device is on servo dolly, and its bottom is connected with adobe holding device.Electro-hydraulic servo cylinder system is a kind of feedback control system being comprised of electric signal process unit and hydraulic power mechanism.Electro-hydraulic servo cylinder system is the output that makes system, as displacement, speed or power etc., can follow the variation of input automatically, quickly and accurately and change, and meanwhile, horsepower output is amplified significantly.In this system, high-performance Hydraulic Elements (comprising hydraulic efficiency servo-valve and hydraulic actuator) are followed low power command signal element action.The mechanical quantity such as normally position, speed etc. that power element is controlled.Command signal element claims again reference signal element, and it sends the command signal that represents position, speed or other amounts.High-powerly can reach more than millions of times with the ratio of miniwatt.Hydraulic efficiency servo is feedback control system, feeds back the signal and instruction signal comparison that represents existing condition, obtains error signal, if error is not zero, just regulate.Adopt the antijamming capability of electro-hydraulic servo cylinder system strong, stable drive, and the Positioning Precision Control of code base is high, can guarantee order and conformability that adobe is stacked, improves the efficiency of follow-up dry, roasting, guarantees that adobe can be not improper and damaged because of stacking.
