Detect ramming volume if 2 testing staff enter tamping pit, exist and detect inaccurate and potential safety hazard; If the testing staff uses laser rangefinder, sound ranger to detect, all want spanning equipment at every turn, surveyed again and removed, detect trouble, labour intensity is large.If use Online Transaction Processing to detect, this system by carrying out detecting in real time to the deflection of strong rammer principal arm jib and step signal of corresponding output is carried out depth test to Programmable Logic Controller and by Programmable Logic Controller according to the corresponding control tamping depth of this step signal test cell in ramming process, also too to bother, and high cost.
3, weight breaks off relations has limitation, weight to enter water when the landform such as compacting shallow water, mud, be absorbed in mud after, the workman can't link up with.
Easy pulleying when 4, hammer ram promotes top set, sting rope.
Summary of the invention
For solving the technical matters of above-mentioned existence, the utility model provides a kind of not dynamic compactor with unhooking automatically to control and automatic detection system, in the course of the work, weight does not break off relations, and can automatically accurately detect ramming volume, and by touch-screen, to monitor in real time, the productive costs such as use manpower and material resources sparingly.
For achieving the above object, the technical scheme that the utility model is taked is as follows:
A kind of not dynamic compactor with unhooking is controlled and automatic detection system automatically, this system comprises Programmable Logic Controller PLC, shaft encoder, pressure sensor, solenoid directional control valve and touch-screen, the input end of described shaft encoder is connected with motor drive shaft, the input end of described pressure sensor is connected with motor, the input end of described solenoid directional control valve is connected with the dynamic compaction machinery Hydraulic Station, the input end of described Programmable Logic Controller PLC is connected respectively with the mouth of shaft encoder, pressure sensor, solenoid directional control valve, and the mouth of described Programmable Logic Controller PLC is connected with touch-screen.
Described touch-screen has data storage and remote transmission, dynamically shows that detection data, different duty parameter are set, historical data gathers integration, protection is reported to the police and the data-printing function.
The utility model automatically calculates hammer ram by Programmable Logic Controller PLC and promotes, falling head and the in good time normal danger of controlling, guarantee when hammer ram drops to ground to brake in time, accurately control the length of steel wire rope looseness, calculate ramming volume by measuring the motor drive shaft corner variable driven by hammer ram gravity and force of inertia, without rammer unhooking, under the gravity and force of inertia effect of suspension hook, steel rope is all the time in tensioning state, avoid steel rope loose ring on winch drum, the rope skipping problem, prevent the disorder cable that winch produces in promoting the hammer ram working process, press rope, sting the bad phenomenon such as rope, touch-screen can be realized the parameter setting, the functions such as various data managements and warning, the rear solenoid directional control valve of the warning that goes wrong starts commutation, guarantee the stable and safe operation of dynamic compaction machinery.
In sum, the utlity model has hammer ram do not break off relations, convenient and swift, can automatically accurately detect ramming volume, touch-screen and monitor in real time, debug simple, cost performance advantages of higher, be applicable to various strong rammer equipment.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail:
As shown in Figure 1, this is the automatic control of dynamic compactor with unhooking and automatic detection system: comprise Programmable Logic Controller PLC1, shaft encoder 3, pressure sensor 4, solenoid directional control valve 5 and touch-screen 2, the input end of described shaft encoder 3 is connected with motor 6 axles, the input end of described pressure sensor 4 is connected with motor 6, the input end of described solenoid directional control valve 5 is connected with dynamic compaction machinery Hydraulic Station 7, the input end of described Programmable Logic Controller PLC1 and shaft encoder 3, pressure sensor 4, the mouth of solenoid directional control valve 5 connects respectively, the mouth of described Programmable Logic Controller PLC1 is connected with touch-screen 2.
This not dynamic compactor with unhooking automatically control and the method for inspection of automatic detection system, realize as follows:
1) by duty parameters such as touch-screen 2 setting dynamic compaction machinery first pressing signal P0, described first pressing signal P0 is that the stressed tension of steel rope but hammer ram be not while breaking away from ground, the initial oil pressure value of pressure sensor 4, Programmable Logic Controller PLC1 records this initial fuel injection pressure signal value P0, gather the current hammer ram degree of depth, hammer the initial point fallen as dynamic compaction machinery next time into shape;
2) motor starts, cable drum rotates and promotes hammer ram, cable drum and motor coaxial rotation, Programmable Logic Controller PLC1 automatically calculates the hammer ram hoisting depth and controls normal danger in good time, hammer ram is promoted to while setting summit, record motor drive shaft anglec of rotation W by shaft encoder 3, described anglec of rotation W, start record during by real-time pressure value P=P0;
3) Programmable Logic Controller PLC1 controls hammer ram and falls by setting summit, and after shaft encoder 3 records motor drive shaft angle-W, brake, continue to descend because the hammer ram force of inertia drives steel rope, and the tape spool △ W that continues to rotate to an angle, according to formula
, wherein S is ramming volume, d is footpath at the bottom of reel;
4) repeating step 2), 3) draw ramming volume next time;
5), when touch-screen 5 shows that the hammer ram whereabouts degree of depth, speed, pressure and other parameters exceed the normal range of control of equipment, Programmable Logic Controller PLC1 controls solenoid directional control valve 5 commutations, and hydraulic pressure is declutched, and on touch-screen 2 display alarm situation and correlation parameter.
Described touch-screen 2 has data storage and remote transmission, dynamically shows that detection data, different duty parameter are set, historical data gathers integration, protection is reported to the police and the data-printing function.The operator can control hammer ram by touch-screen 2 and promotes and descend, and carries out various setting parameters, to meet reliability service under different operating modes, system is controlled flexibly.Touch-screen can by by G proportionately controller PLC1 feedack show the operator with dynamic form.When touch-screen 5 shows that the hammer ram whereabouts degree of depth, speed, pressure and other parameters exceed the normal range of control of equipment, Programmable Logic Controller PLC1 controls solenoid directional control valve 5 commutations, and hydraulic pressure is declutched, and on touch-screen 2 display alarm situation and correlation parameter.
Certainly; above-mentioned explanation is not the restriction to utility model; the utility model also is not limited in above-mentioned giving an example, and the variation that those skilled in the art make in essential scope of the present utility model, remodeling, interpolation or replacement, also should belong to protection domain of the present utility model.
