Description
Technical field
The utility model belongs to building machinery pump truck control technology field, especially relates to control and the display device of a kind of pumping vehicle arm rack angle of revolution.
Background technology
The revolution of pump truck is supported and is realized through rotary reducer rear drive revolution by rotary motor.Because the pipeline of giving arm support oil cylinder transferring oil all supports to each oil cylinder through revolution, so supporting, revolution do not allow unlimited rotation, otherwise may there is the situation that hydraulic oil pipe is twisted into two parts, so revolution must be limited within the scope of 0-360 °, ensure the security of oil pipe.Existing ways to restrain is welded limiting bar on revolution is supported, and revolution is supported on and while rotation, touches two-way limit switch by gag lever post and realize slewing limit.This limit method cannot be in the residing real-time angle of screen display jib, and as long as after the position of limit switch fixed, gyratory directions and the angle of jib have all fixed, in the narrower and small place of working range, pump truck can only, in the situation that one-sided supporting leg is opened, cannot be limited in jib in fixing revolution range.
Summary of the invention
The angle of revolution that the object of the invention is to improve the deficiency of prior art and provide a kind of real-time demonstration jib, can be limited in jib control and the display device of the pumping vehicle arm rack angle of revolution in any revolution range.
The purpose of this utility model is to realize like this, control and the display device of a kind of pumping vehicle arm rack angle of revolution, comprise controller, storage battery, display, be characterized in the power supply of controller+, power supply-end respectively with storage battery+utmost point,-the utmost point connects, after the positive rotary valve M1 of Q0.0 end serial connection of controller, connect storage battery-utmost point, after Q0.1 end serial connection reversible valve M2, connect storage battery-utmost point, the I1.0 end of controller, I1.1 end, I1.2 end, I1.3 end is connected in series respectively approach switch K1, approach switch K2, forward input SB1, after reversion input SB2, connect storage battery+utmost point, the CANH end of controller, CANL end connects respectively the CANH end of display, CANL end, realize the CAN bus communication of controller and display.
Compared with the prior art the utility model has following characteristics and good effect: it is a circular gear wheel that the revolution of pumping vehicle arm rack is supported, its reference diameter is 1.8 meters, the number of teeth is that the rotating angular range of 150. jib is 0-360 °, jib is synchronizeed with the rotation that revolution is supported, jib turns over 360 °, and revolution is simultaneously supported and turned over 150 teeth; Two approach switchs are fixed in the gear outer of supporting in revolution, ensure that jib approach switch rotating time can detect gear signal, change the position between two approach switchs, ensure that the signal that two switches detect meets AB phase rule.In the utility model, two approach switchs are received respectively I1.0 and the I1.1 end of controller, the signal receiving due to approach switch meets AB phase rule, and controller is stored by 4 multiplying powers the umber of pulse receiving, i.e. revolution is supported while turning over clockwise a tooth, the umber of pulse being stored in controller increases by 4, revolution is supported while turning over counterclockwise a tooth, the umber of pulse being stored in controller reduces 4, because revolution is supported for 150 teeth, turn over after 360 °, a circle, the umber of pulse that is stored in controller is 600, be that umber of pulse changes 0.6 ° of 1 jib Angulation changes, so both can obtain the umber of pulse relation corresponding with angle of revolution, can obtain rotating angle value according to umber of pulse, just can set an angle as slewing limit by display like this, replace the effect of mechanical limit switch, an angular range can be set is operated within the scope of this by jib simultaneously, and this spacing scope can be changed flexibly, can complete one-sided supporting leg support works time, need to limit the object of jib operating angle scope, make up the order ground that mechanical limit switch cannot be realized, the dirigibility that has improved control system.
Brief description of the drawings
Below in conjunction with accompanying drawing and example, the utility model is described in further detail.
Fig. 1 is a kind of structural representation of the present utility model.
Embodiment
Embodiment, control and the display device of a kind of pumping vehicle arm rack angle of revolution, with reference to Fig. 1, it is the power supply+end of controller 1, power supply-end respectively with storage battery 2+utmost point,-the utmost point connects, after the positive rotary valve M1 of Q0.0 end serial connection of controller 1, connect the storage battery 2-utmost point, after Q0.1 end serial connection reversible valve M2, connect storage battery-utmost point, the I1.0 end of controller 1, I1.1 end, I1.2 end, I1.3 end is connected in series respectively approach switch K1, approach switch K2, forward input SB1, after reversion input SB2, connect the storage battery 2+ utmost point, the CANH end of controller 1, CANL end connects respectively the CANH end of display 3, CANL end, realize the CAN bus communication of controller 1 and display 3.This forms a kind of structure of the present utility model.
Principle of work of the present utility model is as follows:
The calculating of angle of revolution and demonstration:
At screen setting " revolution zero clearing " button of display 3, press " revolution zero clearing " button by the variate-value zero clearing of 1 li of storage pulse of controller.Press forward input SB1, positive rotary valve M1 obtains electric, jib starts forward, because revolution is supported with 150 teeth, and controller 1 is stored by 4 multiplying powers the umber of pulse receiving, so in the time that jib turned round 360 °, the umber of pulse that controller 1 receives is accumulated as 600, i.e. pulse flip angle degree of the every reception of controller 1 is changed into 0.6 °; Now press reversion input SB2, reversible valve M2 obtains electric, and jib starts to be inverted to reference position, and the umber of pulse that controller 1 receives is less to 0 gradually by 600; Controller 1 just can calculate the residing angle of jib and send on display 3 according to the umber of pulse receiving and show like this.
The setting of slewing limit:
Can only in 0-360 ° of angular range, rotate for meeting jib, jib angle is 0 o'clock, and obtaining of restriction reversible valve M2 is electric, does not allow reversion, can only forward.When jib angle is more than or equal to 359.4 °, limit positive rotary valve M1 electric, do not allow forward, can only reverse.Above function is equivalent to mechanical limit switch, within jib is limited in to 0-360 ° of scope, has realized the effect of limit switch.
The setting of working between any two angles of jib within the scope of 0-360 °:
Suppose to allow jib be operated in (A is less than B) within the scope of angle A-B, rotation jib reaches angle A position, press " spacing 1 " button on sub-screen, this Time Controller 1 is recorded the value of angle A, rotation jib reaches angle B position, press " spacing 2 " button on sub-screen, this Time Controller 2 is recorded the value of angle B.In the time that jib angle is less than or equal to A, restriction reversible valve M2 electric, do not allow reversion, can only forward, angle can only increase.In the time that jib angle is more than or equal to B, limit positive rotary valve M1 electric, do not allow forward, can only reverse, angle can only reduce, and so just can reach jib is limited in to the object of working within the scope of angle A-B.
