The specific embodiment
As Fig. 1, shown in Figure 3, automatic protection levelling instrument of the present utility model is arranged on the automatic paver, is fixed on the paver by a suspension arrangement 1.Be provided with control circuit 12 and displacement transducer 13 in the housing 2, this displacement transducer 13 is a kind of knob resistance potentiometers.In the bottom of this housing 2, laterally run through housing 2 rocker arm shaft 10 is set, this rocker arm shaft 10 is axis of rotation of rotation resistance potentiometer 13, so this just can change the resistance value of potentiometer when rotating.
As shown in Figure 1 and Figure 2, in the outside of this housing 2, fixed installation rocking arm 11 on the rocker arm shaft 10, this rocking arm 11 is stock bodies, one end is fixed on the rocker arm shaft 10, and is provided with counter weight 5 at an end of this rocker arm shaft 10, is in certain equilibrium state to guarantee rocking arm 11.Other end vertical fixing one slide bar 6 of this rocking arm 11, this slide bar 6 is in level when installment state.This slide bar 6 is arranged in the backguy 7 of a level in use, and can slide along this backguy 7.
As shown in Figure 1, the front portion of this housing 2 is provided with control panel, and control panel is provided with switch 8, indicator lamp 3 and adjusts knob 4.The switch, adjustment and the duty that are used for this levelling instrument controller show.Also be provided with on this housing 2 and connect socket 9, be used for being connected of the utility model and paver.
As shown in Figure 3, control circuit 12 of the present utility model is arranged on the inside of housing 2, and the resistance potentiometer in housing comprises resistive film and travelling arm 14 simultaneously, and its effect is a change resistance when rocker arm shaft 10 rotates.
As shown in Figure 4, this circuit comprises signal amplification circuit 15, saw-tooth wave generating circuit 16, comparison circuit 17, Drive and Control Circuit 18 and the control circuit 19 that goes offline.Wherein the input A point of signal amplification circuit 15 connects displacement transducer 13 (P1).This A point also connects the input of the control circuit 19 that goes offline simultaneously.The A point is as the signal input of the signal amplification circuit 15 and the control circuit 29 that goes offline.The output of saw-tooth wave generating circuit 16 is connected to the B point of signal amplification circuit, after sawtooth waveforms that produces and amplifying signal compare, introduce Drive and Control Circuit 18 and carry out control work, be provided with indicator lamp LED1 and LED2 and relay K M1, KM2, KM3, KM4 in the control circuit, the load of relay control paver.And the control circuit 19 that goes offline is introduced the signal that goes offline from 13 (P1) of displacement transducer, and this signal makes relay K M adhesive and the load of paver is no longer changed, and is reported to the police by indicating alarm device, and notifying operation the person in time handle.
Above-mentioned the utility model after installation setting is finished, rides against slide bar 6 in the backguy 7 in use, and the utility model will be controlled the load of paver automatically, realizes Automatic Levelling work.When slide bar 6 when backguy 7 comes off, rocking arm just drives rocker arm shaft and turns over an angle, makes potentiometer change to certain resistance, at this moment just can drive the control circuit work that goes offline, the control paver is in time reported to the police the constant inconvenience of load simultaneously, notifies the user in time to handle.
Above-mentioned levelling instrument of the present utility model has overcome the out-of-control phenomenon that goes offline of existing levelling instrument.
