Description of drawings
Constitute this specification sheets a part, be used for further understanding accompanying drawing of the present utility model and show preferred embodiment of the present utility model, and be used for illustrating principle of the present utility model with specification sheets.Among the figure:
Fig. 1 is the front elevation according to concrete pump truck of the present utility model; And
Fig. 2 is the birds-eye view of concrete pump truck shown in Figure 1.
The specific embodiment
Below in conjunction with accompanying drawing and preferred embodiment, the utility model is described in detail.
Fig. 1 is the front elevation according to concrete pump truck of the present utility model, and this pump truck has been implanted monitored control system.As shown in Figure 1, concrete pumping mechanism assembly 28 is installed on the pump truck chassis 25, this pumping mechanism assembly 28 is by drawing cement concrete in the hopper 24, be pressed into then in the pipeline 23, pipeline 23 is a kind of radial type pipelines, be fixed on the radial type jib, last cement concrete is sent to by end hose 26 and gives directions the place.Radial type jib among Fig. 1 comprises five parts, promptly saves arm 11, joint arm 12, joint arm 13, joint arm 14 and joint arm 15, and the intermediate connecting rod 27 of terminal joint arm 15 makes the terminal operation of jib more flexible.Monitored control system in the utility model can be applied on any known pump truck, and no matter how much quantity of jib is, generally is made up of 3 to 6 joint arms.
Be extended to outside self scope in order to ensure the supporting construction of pump truck, used a kind of outrigger technology, it can be the steadily of centre of gravity range extension of car load near other scopes the chassis.Supporting leg 21 can have various profile.In example, fwd supporting leg 21 is a kind of fixing Retractive legs, and the supporting leg of back is the swing form, and this structure is very common to the people of this area, does not give unnecessary details at this.
According to main thought of the present utility model, pump truck will have the sensor of a large amount of real-time monitoring jib working environment, operating attitude, load state and pumping mechanism assembly 28 information, these sensors send the information of obtaining to central processing unit, by being converted into the numerical information useful to the operator after the central processing unit process of compilation.Central processing unit displays these information by the CAN protocol interface by graphical interfaces, for the operator provides operational circumstances information and other trend signs the most timely.
According to the above, shown useful information can help the operator independently to move concrete pump truck on the screen, and makes proper operation.For example jib is moved to the work area, perhaps jib is regained safety zone, perhaps change rate of pumping to avoid resonance effect.By this function, the prompting operation concrete pump truck that the operator provides at that time operating attitude and condition of loading coupling system, rather than only rely on operator's self working experience.
Another angle, the novel part of this utility model are in conjunction with the data after the process central processing unit for processing, whether the continuable check pump truck of system is near the dangerous point.
In the machine operation process, if a precarious position is arranged near default critical value, for example during 90% limit, central processing unit will provide an alarm and visual signal, stop the operation of a machine gradually simultaneously or allow machine gradually away from the state of danger.
The pump truck precarious position that the utility model can be monitored comprises following several respects: 1) with ground-surface situation and the chassis level situation of contacting; 2) car load that causes of jib motion is tumbled constantly; 3) the steady stability situation on chassis; The jitter conditions of the jib in 4) the pumping process.
Precarious position information above-mentioned is that the sensor by ad-hoc location in the system provides, and these sensor signals are delivered to the information that the central processing unit post-processing becomes reflection car load geometric parameter, thereby judges power and the action that acts on this moment on the machine.These data compare with the safe condition data that are pre-stored in the memory device then, just can predict at any time that whether approaching the imminent action of machine or will be near precarious position.
At the various different critical states in the above argumentation, sensor need provide following information:
Situation 1: with ground-surface situation and the chassis level situation of contacting.
Detect concrete pump truck and when contacting situation, need arrange force gauge with ground-surface on supporting leg, for example strain sensor detects the strained situation when supporting leg 21 lifting chassis 25, pressure sensor detection supporting leg 21 pressure condition of support oil cylinder rodless cavity.When detecting the horizontal situation of car load, need the angular transducer of diaxon, be used to detect the angle of chassis vertical and horizontal.
Situation 2: tumble constantly
The trend of tumbling on the chassis 25 that jib causes can by joint on the arm 11 the detected level angle of angular transducer and joint arm 11 oil cylinder upward pressure sensor to hydraulic-driven power judge.
Situation 3: stability
Calculate the stability of car load and must consider the above-mentioned trend of tumbling immediately (situation 2), the horizontal situation on the position angle of jib and chassis (situation 1) also needs the expansion situation of supporting leg at last.Except top situation 1 and situation 2 detected information, also need the extension elongation of front supporting leg 21, the start point of back supporting leg 21, and the angle of rotary table 22 rotations.
Situation 4: the jib swing that resonance causes
This situation needs real-time detection jib or the wherein angle variation of a joint arm, detects the oil cylinder working-pressure of the first segment arm 11 of control jib motion simultaneously.Angular dimension during the jib swing depends on the relative angular position situation between each separate unit of jib, and is simultaneously also relevant with the pumping frequency of pumping mechanism assembly 28.Therefore, by angle that detects first segment arm 11 or the angle position of detecting other arms 11,12,13,14 of jib, just can predict the swing situation of jib in conjunction with the pressure changing in the oil cylinder of first segment arm 11.Be noted that at last tube vibration by which joint arm is not caused, all can catch rapidly by sensor.
Information of obtaining based on sensor in above-mentioned and default security parameter and function, the monitored control system in the utility model just can determine the especially operating range under each operating mode of concrete pump truck of portable pump.In fact, at absolute rating and the end position in the above-mentioned various conditions of mentioning, a maximum safe range percentum can be arranged all, in case surpassed this percentum, system will provide alarm also automatically away from precarious position.For example change the frequency (as the pumping frequency) of external force.
Design different from the past, monitored control system of the present utility model is not limited to the operating range of pointing out that simply the operator is exercisable and can not operating, allow the operator go decision how to move voluntarily, but monitored control system itself just can be monitored the various actions in the machine use, avoids the generation of unpredictable action simultaneously.
In the process of convergence limit condition of operation, machine also has a very big operation interval, in fact this is clearly, sometimes pump truck need carry out accurate cloth at the safe range boundary vicinity, but because mistake judges that just may get rid of this only is the zone that has potential danger, system of the present utility model is different, it can judge the scope of hazardous location accurately, these scopes are those zones that must cause damage to machine or operator, but this particularity has also enlarged the opereating specification of machine simultaneously.
The most significant difference of monitored control system is its monitoring behavior to critical operating mode in the utility model, and this behavior is not simply to the slowing down or interrupt of system acting, and needs to allow artificial revising sometimes yet.For example under a kind of special operation condition, critical conditions is very approaching, supposes artificial machine is retracted to safety zone also allows of operator.
In the above-mentioned related various critical operating mode, situation 1 and 2 can be thought the basic input of system, judges whether to allow to be about to the power operation that carries out by it.So, if in the back in the operating process service conditions exceeded default critical value and for example exceeded 90% of maximum limit, operation will be prevented at once, satisfies again up to above-mentioned service conditions.For example erect and hang load when supporting leg 21 supports sinking of grounds or wrongful motion arm, this situation will not take place when perhaps the supporting leg expanded position did not meet the demands.
Situation 3 and 4 operating speeds that need by monitored control system fit adjustment pumping mechanism assembly 28.Thereby, if detecting machine, central processing unit exceeded default stability limit, it will change the position of jib, for example stops the rotation of jib and stretches out action, perhaps the state that stretches out of jib is retracted in the critical range.Machine is remained in the safer scope always.In this case, the artificial proper operation of operator also is acceptable, but this operation must be the direction opposite with precarious position, and these are judged all can continuously effective, is back in the critical range fully until machine.
The control operation of system is similar (can not influence the process of operation) in situation 4.In fact, in this case central processing unit can testing pump the swing situation of jib and each parts thereof in the work feed material process.If the frequency of swing is near the pumping frequency of pumping mechanism assembly 28, central processing unit can change frequency of operation, concrete flow velocity, thus avoid the resonance effect of complete machine.Because system can detect the swing situation in advance before the operator perceives swing, therefore can change the pumping frequency more efficiently, avoid the generation of improper stress on jib hinge-point and the chassis from the source.So these all can have actv. weakening effect to jib.
The policer operation of the movable parts that is undertaken by central processing unit can well realize by dynamic hydraulic control loop and the electromagnetic valve that is installed in the loop.As mentioned above, the feature of system is no matter when critical condition is broken in the utility model, system all can with a kind of smoothly slowly mode movable parts is recovered to perch, a slope that reduces current motion for example is provided.This need be realized that unexpected like this motion is regulated the risk that causes and just reduced greatly by an apportioning valve.
Monitored control system of the present utility model also provides a kind of jib motion self learning system.By the logical process that the statistics industry is all known, we get off the jib operation that the operator carries out with a kind of special encoded recording.System can also note in order by the operation of as above encoding in operator's certain hour.When repeating these operations, system can carry out self study, and whether the decision operation of intelligence exceeded precarious position above-mentioned, to provide correct jib running orbit.
There are a lot of modes to realize top this target, depend primarily on the electric-control system and the programming language of selection; Yet the utility model has clearly been explained the logical order of central processing unit operation and the target that will reach.
Be used for all being stored in a suitable data memory device to the data of operator's indication and detection complete machine state, for example in the memory body of central processing unit, operation also goes on record improperly simultaneously, and what for example central processing unit was confirmed as can not operate, and goes beyond the limit of the operation of scope.These data storage are got off and are used to offer equipment manager, the equipment owner and other people who administers machine maintenance.The time schedule that exceeds or can be used to provide a daily attention operation according to machine near time of precarious position.
In fact, these data have provided full and accurate information, and the maintenance time table is combined with the maximum capacity of actual conditions and machine.For example, can provide the concrete time of implementing attended operation, safeguard prompting to the operator simultaneously based on the parameter preset central processing unit, maintenance at this moment may early than or be later than in the daily use and safeguard.
The maintaining operation accurately and timely that system provides can allow designer or even machine building works merchant obtain bulk information, in fact, long-term various information of collecting can sum up optimized maintaining experience, particularly at the user of some users or a certain type, simultaneously design and production phase just arrange properly these attended operations maintenance cost can be used really need the place, farthest guarantee the output of minimum maintenance cost.
What the front was very detailed is described this monitored control system, comprises the sensor of a series of networkings, central processing unit, and the moving-member of proportional control and some storage equipments, these have realized the purpose that the front is discussed fully.
Monitored control system provided by the utility model can detect the data of machine real time operation, and based on these master datas, system can revise near the quick automatically operation to the critical conditions, but makes it to return in the opereating specification rapidly.And, by analysis to service data in the memory device, the time that each machine maintenance operation of the precognition that system can be correct is carried out; System can also obtain the important information of maintenance time table.
The utility model is including, but not limited to the specific descriptions that this paper did, and some other the concrete device in protection domain.
Finally, the pump truck operation is obviously simplified, even if therefore unskilled operator also can safe operation pump truck by monitored control system of the present utility model.
The above is a preferred embodiment of the present utility model only, is not limited to the utility model, and for a person skilled in the art, the utility model can have various changes and variation.All within spirit of the present utility model and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
