Master winch motor 202 main shaft that this detailed description of the invention is rammed in stake control unit 2 is connected with winching barrel 206 by clutch 205, brake 207 controls the rotation of winching barrel 206, when 207 points, brake, clutch 205 close, master winch motor 202 drags pile monkey 209 and promotes, when brake 207 close, clutch 205 timesharing, pile monkey 209 freely falls under gravity, completes and once rams operation; Manual rammer stake, then by operator's solenoidoperated cluthes 205 and brake 207, is automatically rammed stake operation by controller operated clutch 205 and brake 207, is reduced the labour intensity of workman, improve efficiency and the quality of piling work.
The process of automatic rammer stake is: (1) setting parameter: set on operation interface, and hoisting depth scope rammed by pile monkey, expects that stake is dark, and single is rammed and expected feeding depth scope, the parameters such as current threshold;
(2) automatically ram stake and prepare one: controller sends signal, makes 205 points, clutch, 207 points, brake, after time delay 3 second, closed brake 207, this step guarantees that pile monkey 209 falls earthward;
(3) automatically ram stake and prepare two: start master winch motor 202, after electric motor starting, solenoidoperated cluthes 205 close, 207 points, brake, then detects current of electric, after electric current exceeds setting threshold value, solenoidoperated cluthes 205 points at once, brake 207 closes, simultaneously proximity switch 216 counter O reset, and this step guarantees that hoist engine cable is in tensioned state;
(4) pile monkey is promoted: switch proximity switch counter direction for counting up; Solenoidoperated cluthes 205 close, 207 points, brake, and pile monkey 209 raises under master winch motor 202 drags, and measure pile monkey 209 height in this process; After pile monkey 209 arrives the rammer stake height expected, solenoidoperated cluthes 205 points, brake 207 closes;
(5) dropping hammer: switch proximity switch counter direction for subtracting counting, solenoidoperated cluthes 205 points, 207 points, brake, pile monkey 209 movement of falling object under gravity, measuring pile monkey 209 height in real time; When after the expectation feeding depth that the single of pile monkey 209 arrival setting is rammed, control brake 207 is closed; If soil property is closely knit, pile monkey 209 cannot arrive the feeding depth that single is rammed, then, after fall time is more than 3s, control brake 207 is closed;
(6) the dark measurement of stake: switch proximity switch counter direction for counting up, solenoidoperated cluthes 205 close, 207 points, brake, measured motor electric current, after electric current exceedes setting threshold value, the value writing down current proximity switch counter is that actual stake is dark, calculates the actual amount of feeding that this is rammed, and revises the amount of feeding expecting that single is rammed, and height rammed by correction pile monkey, judge that dark whether the reaching of actual stake expects that stake is dark, if reached, Automatic piling stops; If do not reached, then return the 4th step, continue Automatic piling operation.
36 magnetic links winching barrel 206 are equipped with, when winching barrel 206 rotates, proximity switch 216 can sense the rotation of winching barrel 206, by the reading to clutch 205 deciliters status informations, the information of rotation direction can be obtained, i.e. clutch 205 timesharing, winching barrel 206 rotates forward, proximity switch 216 signal forward counting; When clutch 205 closes, winching barrel 206 reverses, and the negative counting of proximity switch 216 signal, proximity switch count value is exactly the positional information of pile monkey 209.
Ram the movement of falling object of stake process complete ram time, winching barrel 206 is rotated further under effect of inertia, and now hawser 208 relaxes, causing the error of the dark measurement of stake, is head it off, proximity switch 216 and current sensor are coordinated, it is dark that the hoist links after dropping hammer measures stake; The load condition of hoist engine has three kinds, and the first state is clutch 205 master winch motor 202 no-load running when separating, and electric current is no-load current; The second state is that clutch 205 closes, and master winch motor 202 drives winching barrel 206 and pile monkey 209 upwards to promote state, and now motor overcomes pile monkey 209 gravity acting, and electric current is larger; The third state is that clutch 205 closes, but the hawser 208 of master winch motor 202 is in relaxed state, master winch motor 202 only drags winching barrel 206 and rotates, the electric current of this state is a little more than no-load current, but still there is larger gap with pile monkey 209 motor current, when peg is dark, the electric current of current threshold slightly larger than state three of master winch motor 202 need be set, when actual current exceedes threshold value, can judge that elevator cable is just in tensioned state, now count value is exactly pile foundation actual grade.
This detailed description of the invention achieves automatically rams stake, and stake machine balanced support controls, and position of p ile machine adjustment operation control, operated from a distance control, reinforcing bar roll the functions such as cage lifting auxiliary operation control, electric motor protecting and process display:
(1) automatically ram stake to control: operator inputs and expects driving depth on guidance panel, pile monkey rising height, single drops hammer after feeding depth range information, system automatically completes and beats operation continuously, the dark measuring unit of stake of system, can in piling work be carried out, to pile monkey hoisting depth, piling feeding depth is measured in real time, because piling process hoist engine drum vibrates is violent, there will be the non-state tightened in cable wire folding and unfolding process more simultaneously, general photoelectric encoder detection system can not adapt to operating mode severe like this, native system adopts proximity Hall switch to be used for cylinder rotation measuring, in piling process, system is measured in real time to the effect of dropping hammer at every turn, according to target depth, the progress status of piling, adopt machine learning algorithm, to feeding depth pre-estimation of dropping hammer next time, carry out with this weight rising height that operation is beaten in Self Adaptive Control next time, optimize piling efficiency, farthest improve Piling speed.
(2) stake machine balanced support positioning control: stake machine configures high-precision dual-axis level measurement unit, operating personnel can observe the output signal of XY levelness on touch screen, descending operation is carried out to four supports, the height of four feets of adjustment stake machine, complete pile forming machine horizontal adjustment controls, and rams in stake process, system Real-Time Monitoring level measurement data, after levelness exceedes certain limit, system can produce to report to the police and export, and stops piling work.For control of advancing, manually can operate the crawler belt of advancing of a machine, complete the operation controlling the advance of crawler belt, retrogressing and rotation, and then complete pile foundation positioning action.
(3) hoist controlling function: pile driving system is furnished with secondary hoist engine, secondary elevator mainly completes the operation at the uniform velocity promoting decline, and then realizes auxiliary lifting function, and sleeve pipe of namely driving piles is installed, and reinforcing bar rolls the tasks such as cage lifting.
(4) network monitoring function: system can configure CAN mixed-media network modules mixed-media, pass through mixed-media network modules mixed-media, operator can obtain piling information, when multiple stage pile driver runs simultaneously, networking can be carried out to many machines, in the state of host computer Centralized Monitoring all piles machine, and remote monitoring can be carried out.
This detailed description of the invention both can carry out automatic improving to existing manual pile driver, and can be applicable to again the manufacture of full-automatic pile driver, automaticity is high, easy to operate, reduce the labour intensity of workman, improve efficiency and the quality of piling work, there is wide market application foreground.
