After the structure is adopted, a calibration value is calibrated as the standard after the front wheel is straightened, a sensing device is used for detecting the deflection position and the alarm device is used for giving an alarm in a work process, then the front wheel can be straightened after operating the reset button so that it can be guaranteed that the hinging oil cylinders can be reset in time after the front wheel is used in an inclined mode, reset accuracy is also guaranteed, running deflection is avoided, and running safety is guaranteed.
Description
Technical field
The utility model relates to a kind of land leveller servicing unit, and specifically a kind of land leveller front-wheel straightening device, belongs to pavement construction machinery engineer operation technical field.
Background technology
Land leveller is a kind ofly to take perching knife as main, is equipped with other multiple interchangeable apparatus for work, carries out the engineering machinery of formation of land and plastic operation; In work progress, available land leveller carries out roadbed base treatment, completes turf or top layer is peeled off; The section of trimming embankment; Other brush side slope; Excavation road groove and gutter; On roadbed, mix and stir, paving concrete pavement base material; Land leveller can be used for trimming and maintenance dirt road, removes road snow.
In prior art, most of land levellers are all with front-wheel tilt function, use front-wheel tilts, can reduce turning radius, make land leveller turn to maneuverability more, but traditional front wheel lean device is unreasonable because structure arranges, it is unreliable often to use, and common problem is that front-wheel tilt to be used the hinged oil cylinder or reset inaccurate of not resetting later, there is driving running deviation, thereby affect traffic safety.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of rational in infrastructure, resets reliable, and safe land leveller front-wheel straightening device.
In order to solve the problems of the technologies described above, land leveller front-wheel straightening device of the present utility model, comprise controller and the electromagnetic valve YVA and the electromagnetic valve YVB that are connected to two oil cylinders can controlling front-wheel deflection on controller, also comprise the checkout gear for detection of front-wheel inflection point that is connected on controller and for sending the warning device of indicating status information, on described controller, be also connected with the reset button that can open reset work.
Described checkout gear is the position sensor SQ that lays respectively at two oil cylinders inside or be installed in parallel in respectively oil cylinder outside; The signal output part of described position sensor SQ is linked in controller.
Described checkout gear is for to be arranged on approach switch SQ1 and the approach switch SQ2 of two oil cylinder outsides respectively, and the signal output part of described approach switch SQ1 and approach switch SQ2 is all linked in controller.
Described warning device is the alarm lamp HL being serially connected on controller.
Adopt after above-mentioned structure, due to the controller and the sensing device that arrange, by the signal access controller of sensing device, by controller, control the corresponding valve group of oil cylinder, one of outer setting is ajusted button and alarm lamp automatically, front-wheel is ajusted rear demarcation and be take calibration value as benchmark, in the course of work, by sensing device, detect inflection point and report to the police by warning device, then operating reset button just can ajust, can guarantee that thus front-wheel tilts to use can reset in time later hinged oil cylinder and reset accuracy, avoid occurring driving running deviation, guaranteed traffic safety.
Accompanying drawing explanation
Fig. 1 is the first embodiment schematic diagram of the utility model land leveller front-wheel straightening device;
Fig. 2 is the second embodiment schematic diagram of the utility model land leveller front-wheel straightening device.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, land leveller front-wheel straightening device of the present utility model is described in further detail.
Embodiment mono-:
As shown in Figure 1, land leveller front-wheel straightening device of the present utility model, comprise controller and the electromagnetic valve YVA and the electromagnetic valve YVB that are connected to two oil cylinders can controlling front-wheel deflection on controller, also comprise the checkout gear for detection of front-wheel inflection point that is connected on controller and for sending the warning device of indicating status information, said checkout gear is that to lay respectively at two oil cylinders inner or be installed in parallel in respectively the position sensor SQ of oil cylinder outside; The signal output part of position sensor SQ is linked in controller, and said warning device is the alarm lamp HL being serially connected on controller; On controller, be also connected with the reset button (automatically ajusting switch) that can open reset work.
Its operating principle is as follows:
The present embodiment can be selected built-in sensors oil cylinder or be installed in parallel in the displacement transducer of oil cylinder outside, front-wheel is just put, calibration sensor value X, controller contrasts the median X of the sensor signal instantaneous value Y of reception and demarcation, if two numerical value are unequal, alarm lamp HL lights, now illustrate that front-wheel just do not putting, press and automatically ajust switch (Self-resetting), controller receives signal, start to compare, work as Y>X, YVA corresponding points output of controller, open YVAFa road, until during Y=X, controller YVA corresponding points are not exported, and HL corresponding points are not exported simultaneously, lamp goes out, this time relatively export end cycle, work as Y<X, YVB corresponding points output of controller, opens YVBFa road, until during Y=X, controller YVB corresponding points are not exported, and HL corresponding points are not exported simultaneously, lamp goes out, and this time relatively exports end cycle.
Embodiment bis-:
As shown in Figure 2, land leveller front-wheel straightening device of the present utility model, comprise controller and the electromagnetic valve YVA and the electromagnetic valve YVB that are connected to two oil cylinders can controlling front-wheel deflection on controller, also comprise be connected on controller for detection of the checkout gear of front-wheel inflection point (state of oil cylinder) and for sending the warning device of indicating status information, said checkout gear is for being arranged on respectively approach switch SQ1 and the approach switch SQ2 of two oil cylinder outsides, the signal output part of approach switch SQ1 and approach switch SQ2 is all linked in controller, said warning device is the alarm lamp HL being serially connected on controller, on controller, be also connected with the reset button that can open reset work.
Its operating principle is as follows:
The present embodiment can be selected two approach switch type sensors; Front-wheel is when meta, and sensor SQ1 and SQ2 no signal are exported.If during front-wheel left avertence, SQ1 detects signal, closure, transmission+24V is to controller, alarm lamp HL is bright, presses reset switch SB, and YVB corresponding points output of controller, opens YVBFa road, until SQ1 can't detect signal, disconnect, controller is not exported, and this time resets and finishes.When if front-wheel is taken back, SQ2 detects signal, closure, and transmission+24V is to controller, alarm lamp HL is bright, presses reset switch SB, and YVA corresponding points output of controller, opens YVAFa road, until SQ2 can't detect signal, disconnect, controller is not exported, and this time resets and finishes.
During use, when the front-wheel dump ram of land leveller is not during at meta, warning device lights, if driver need to reset to front-wheel, touches adjusting device, and controller receives after signal, starts to control oil cylinder, makes it get back to meta.When oil cylinder, get back to after meta, lamp goes out.
