Description
One, technical field
The present invention relates to a kind of touch-down self-stopping device of drill rod of rotary drilling rig, belong to the underground construction mechanical field.
Two, background technology
Rotary drilling rig is a kind of multi-functional, high efficiency pouring pile hole equipment.Noise was little when it had construction, friction, no soil deformation, displacement; Little to surrounding constructure influence, the stake footpath is big, and length can freely be selected; And can enlarge the bottom, pile body stiffness is big, and bearing capacity of single pile is big; Efficient is high, and system stake low cost and other advantages, is approved by domestic basic engineering institute and unit in charge of construction at present.Along with the increase of rotary drilling rig recoverable amount on market, the user also proposes higher requirement to the functional performance of rotary drilling rig.As: rotary drilling rig often occurs because of the operator error causes the phenomenon of master winch wire rope disorder cable, thereby causes wire rope low application life in work progress, and sounding error is big, and is very big to this user's complaint.
That has only at present that the requirement operator do not stop in transferring the process of master winch checks that putting the rope form attitude prevents disorder cable, so very easily causes operator tired.The producer that has is equipped with camera on the master winch position, operator can directly be observed the process of transferring of master winch in driver's cabin.If but " shrinkage cavity " phenomenon appears in the stake hole, drilling rod will block in the position of " shrinkage cavity ", and operator is handled the untimely wire rope disorder cable phenomenon that also occurs easily.
Three, summary of the invention
Patent of the present invention provides a kind of touch-down self-stopping device of drill rod of rotary drilling rig, and purpose is master winch to be transferred the intelligent control of process realization of wire rope, thereby judges that automatically drilling rod is at the bottom of the hole, hole or " shrinkage cavity " position, alleviates the labour intensity of operator.
Technical solution: be provided with electromagnetic valve between handle of the present invention and the main control valve; Thereby the bearing pin axial region is sensor to be installed in cavity, the cavity form the bearing pin sensor; Bearing pin sensor signal input is connected with pulley; Bearing pin sensor signal output is connected with the Vehicle Controller signal input part, and the Vehicle Controller signal output part is connected with pilot solenoid valve and automatic stop selector switch respectively through relay, embeds the drilling rod automatic stop of contacting to earth at Vehicle Controller simultaneously and controls functional module.
Vehicle Controller carries out initialization in the back that powers on to the drilling rod automatic stop control functional module of contacting to earth; Then the bearing pin sensor signal that collects is put, analyzes in order the back and obtain reference data; Reference data steel wire rope tension data real-time and initial setting compare; If reference data is less than the data of setting then Vehicle Controller sends control signal; Simultaneously current depth measurement data are also caught up with the depth measurement data of preserving when once holing and are compared, if data of preserving when hole less than the last time then send " shrinkage cavity " and report to the police are in position at the bottom of the hole, hole otherwise give tacit consent to drilling rod; If reference data is greater than the data of setting then Vehicle Controller is not sent out control signal, operator is normally transferred drilling rod.
Bearing pin is the cylinder of a hollow, and profile customizes arbitrarily according to the needs that pulley is installed.
The bearing pin sensor is the Wheatstone bridge formula sensor that foil gauge is formed.
The present invention is on the basis that keeps original hydraulic system, electric system, frame for movement; Increase a Wheatstone bridge formula bearing pin sensor of forming by foil gauge; Make sensor generation deformation I under the reverse support force III acting in conjunction of the external bearer power II and the left and right sides, and this deformation that is caused by shear stress converts the signal of telecommunication that is directly proportional with sensor load to.Vehicle Controller collects the signal of telecommunication that the bearing pin sensor spreads out of, and it is put in order, analyzes, and judges whether drilling rod touches ground.Just send control signal if touch ground, cut off the working oil path of master winch motor through pilot solenoid valve, thus control master winch wire rope continue transfer, realize the drilling rod automatic stop function of contacting to earth.
Four, description of drawings
Accompanying drawing 1 is the control principle sketch map;
Accompanying drawing 2 is a bearing pin sensor force diagram;
Accompanying drawing 3 is the controller function logic chart.
Five, the specific embodiment
As shown in Figure 1; Between handle 1 and main control valve 3, install electromagnetic valve 2 additional; Bearing pin 5 axial regions are cavity, sensor is installed in the cavity forms the bearing pin sensor, and bearing pin sensor signal input is connected with pulley 6; Bearing pin sensor signal output is connected with Vehicle Controller 8 signal input parts, and Vehicle Controller 8 signal output parts are connected with pilot solenoid valve 2 and automatic stop selector switch 7 respectively through relay.Vehicle Controller 8 collects the signal of telecommunication that the bearing pin sensor spreads out of, and has contacted to earth if judge drilling rod 9, and then Vehicle Controller 8 sends control signal; Simultaneously the drilling rod automatic stop selector switch 7 that contacts to earth just in time is in " opening " state, then pilot solenoid valve 2 electric, cut off the control oil channel of guide's handle 1; 3 times metas of main control valve; Close the working oil path of master winch motor 4, wire rope 10 is being with drilling rod 9 will stop to transfer, though operator was also controlled guide's handle 1 and done the action that master winch is transferred this moment; The intention of hand but the master winch motor has not redoed, the automatic stop function thereby the completion drilling rod contacts to earth.Automatic stop selector switch 7 is in " cutting out " state if drilling rod contacts to earth, and then cancels the drilling rod automatic stop function of contacting to earth, and can change the maintaining work of normal device such as master winch wire rope.
Fig. 2 is a bearing pin sensor force diagram, and the bearing pin sensor is the Wheatstone bridge formula sensor that foil gauge is formed.Form by bearing pin 5, measurement mechanism 1.Bearing pin 5 is cylinders of a hollow, and profile can customize arbitrarily according to the needs that pulley is installed, and the Wheatstone bridge that measurement mechanism 1 is made up of foil gauge is installed in bearing pin 5 inner chambers.The input form of bearing pin sensor force is a shearing force, make sensor generation deformation I under the reverse support force III acting in conjunction of the external bearer power II and the left and right sides, and this deformation that is caused by shear stress converts the signal of telecommunication that is directly proportional with sensor load to.
Fig. 3 is the controller function logic chart, on the basis of Vehicle Controller 8 original control functions, embeds the drilling rod automatic stop functional module of contacting to earth.Vehicle Controller 8 carries out initialization in the back that powers on to the drilling rod automatic stop control functional module of contacting to earth, and then gathers bearing pin sensor electrical signal with every 20ms, and 5 groups of data that whenever collect are got its average, obtains reference data.Reference data steel wire rope tension 10 data real-time and initial setting compare; If reference data is less than the data of setting then Vehicle Controller 8 sends control signal; Current depth measurement data of while are also caught up with the depth measurement data of preserving when once holing and are compared; If data of preserving when holing less than the last time then send " shrinkage cavity " and report to the police, otherwise acquiescence drilling rod 9 is in position at the bottom of the hole, hole.If reference data is greater than the data of setting then Vehicle Controller 8 is not sent out control signal, operator is normally transferred drilling rod 9.
