Below the control procedure using the full-automatic coal sampling prototype of vehicle-mounted removable of the present invention to carry out coal sampling and preparing operation is described, with the operation using method of coal sampling and preparing machine clearly of the present invention.
Accompanying drawing 6 schematically provides the process that application coal sampling and preparing machine of the present invention carries out coal samling, control sampling prototype by control system as shown in Figure 6 and move to the fortune coal coal bin of coal sample to be collected, then carry out sampling-sample presentation-sample preparation (fragmentation, division, collection sample)-abandon the work such as sample according to following manipulation process.
The full-automatic coal sampling prototype of vehicle-mounted removable of the present invention needs to make motor car engine power takeoff control to make it engage by transfer gear with hydraulic plunger variable, pump quantitative gear pump before the procedure.Gathering and processing coal sample process is full automatic working, and specific works process is as follows:
Sampling prototype open beamhouse operation: first by automobile, coal sampling and preparing machine is moved near dump to be sampled (or coal car/coal bin), then open automobile chassis 1 being installed front hydraulic leg 4 and rear hydraulic leg 8, and make front and back hydraulic leg reach ground with vertical direction in the horizontal direction by adjustment and support firm.Then in vehicle-mounted OPS, computer program sends sampling apparatus 7 and opens order, big arm cylinder 12 in sampling apparatus 7 makes large arm 11 rise to certain position; oil cylinder of small arm 13 motionless (at this moment oil cylinder of small arm 13 is that top is to the longest position); simultaneous retractable arm 15 reaches certain position; pivot angle oil cylinder 17 is failure to actuate; then sampling apparatus 7 rotates to the anglec of rotation of working position by base 10, near any one working position that sampling head is arrived in 6 working positions of Stochastic choice.
Sampling prototype gather and process sample operating process:
Computer program sends bicycle sample command, and bicycle sampling refers to that namely sampling apparatus completes one bout action: choose and adopt a little → carry out sampling head → revolution sample presentation → sample preparation → the be turned back to working position → continue next to adopt point sampling of sampling → promote.The oil cylinder of sampling apparatus 7 is all equipped with stay wire sensor, the pivoting support of base 10 is equipped with on rotary encoder, sampling head 19 and obliquity sensor is housed.These sensors all can accurately for the control of action provides data, and PLC processor sends corresponding action command by analyzing these data.Concrete action refers to: sampling apparatus 7 is after working position receives sampling instruction:
(1) the simultaneously action of forearm 14, telescopic arm 15, base 10 arrives certain sampling point position (piling 300mm apart from matchmaker high), and the action of pivot angle oil cylinder 17 discontinuity is to adjust sampling head 19 in the process, to be sampled 19 adjust angle after lock;
(2) forearm 14, telescopic arm 15, pivot angle oil cylinder 17 action simultaneously, ensure that sampling head 19 starts to sample with same not varied angle downwards or obliquely, and the coal sample of collection is just transferring upwards to be delivered to storage bin by rotating helical blade in sampling head;
(3) after sampling head 19 adopts designated depth; the action simultaneously of forearm 14, telescopic arm 15; make sampling head 19 upwards be risen to apart from dump predetermined altitude (300mm) by even acceleration; in this process, sampling head continues to rotate forward until arrive above materials device processed; and sampling head is unlocked, and is in free operating state;
(4) base 10, telescopic arm 15 action are simultaneously turned back to certain angle to the even acceleration of sample preparation device 3 feeder hopper 20, and then stop, this process sampling head is in free state;
(5) when then forearm 14 and telescopic arm 15 action simultaneously make sampling head storage bin bin gate drop to apart from sample preparation device feeder hopper 20 certain altitude, again turn round respective angles, the storage bin bin gate of sampling head is made to turn to directly over sample preparation device feeder hopper 20, bin gate oil cylinder 33 action makes storage bin bin gate open, coal sample to be collected closes bin gate after falling into sample preparation device, and sampling head 19 keeps locking state in the process;
(6) sampling head 19 unlock make it be in free state, oil cylinder of small arm 13 action, make sampling head 19 upwards even acceleration rise to former working position height;
(7) start to select another sampled point at random to this dot system, base 10 revolution accelerates to new sampled point angle, and then the simultaneously action of forearm 14, telescopic arm 15 and pivot angle oil cylinder 17 makes sampling head 19 adjust to above this sampled point to carry out next circulating sampling.
In the said process of bicycle sampling, preferred big arm cylinder 12 remains to be failure to actuate in the position of adjusting, and " forearm 14 action " described in above process refers to that it moves relative to large arm 11 under the effect of oil cylinder of small arm 13, described " telescopic arm 15 action " refers to that it stretches under the effect of telescopic boom cylinder 16 in forearm 14, described " base 10 action " refers to that it horizontally rotates under the effect of swing bearing, and described " pivot angle oil cylinder 17 action " refers to that it drives four-bar mechanism 18 to move by hydraulic jack.
When bicycle sampling revolution, computer program also can send sample preparation instruction simultaneously.That is: breaker 21 working reduction coal sample → reduction device 23 works and carries out division → collection sampling device work to coal sample and collect coal sample (collection sample bucket 28 full then automatically switch next collection sample bucket 28).When sampling apparatus 7 starts to turn round to sample preparation device 3, crusher motor starts, breaker 21 is worked, then division motor 27 makes reduction device 23 start, coal sample after fragmentation is slipped into abandoning sample case 2 by reduction device 23 part by rejected material chute 24, and a part is slipped into collection sample bucket 28 by the chute 25 that gathers materials.After aggregate tube is full, ultrasonic sensor obtains signal transmission to system, program is given an order to direct current generator 32 after judging, make it drive bevel pinion 31, bevel pinion drives large helical gear 30, and large helical gear 30 drives collection sample pallet 29 to rotate, pallet 29 is equipped with travel switch, when collect sample bucket 28 vertical alignment gather materials the discharging opening of chute 25 time, travel switch obtains signal, and direct current generator is stopped.Collection sampling device also can support that operating personnel manually select bucket position and the full rear two kinds of modes that automatically switch of material.After sample preparation completes, sample preparation device quits work.
Sampling prototype recovery operation: after sampling, sample preparation, collection sample terminate, operating computer program sends jib and regains instruction, that is: sampling head is made to be in free state, rotary table 10 makes sampling apparatus 7 be turned back to zero-bit, then telescopic arm 15 is retracted into zero-bit; forearm 14 supports dominant bit, and then large arm 11 nutation, is located on bracing frame.Front and back hydraulic leg is regained, and so far automobile chassis 1 can sail out of work place.
Below be only that the preferred embodiment of the present invention is described; technical scheme of the present invention is not limited to this; the any known distortion that those skilled in the art do on the basis that major technique of the present invention is conceived all belongs to the claimed technology category of the present invention, and the concrete protection domain of the present invention is as the criterion with the record of claims.
