This embodiment is when the circulation of filling by pressure goes wrong, will judge the scraper blade according to hydraulic system's relevant operation parameter, whether the slide moves in place, if not in place, then automatic control mends and scrapes (going upward) the solution, control the circulation of filling by pressure of rubbish compression car promptly through compiling new control logic, eliminate the jam condition in the filler, it is too much to have avoided rubbish in the filler, the scraper blade, the slide moves not in place, the problem of rubbish can't be effectively filled, need not artifical the solution, work efficiency and customer satisfaction have been improved, it is effectively filled to ensure to fill every time, and the work efficiency is improved, and the waste of the energy is avoided.
In the preferred embodiment of the present application, in the press-filling process, whether the scraper and the slide plate move in place is judged according to the relevant operation parameters of the hydraulic system, and the method specifically comprises the following steps:
s101, when a scraping plate scraping working condition is detected, when a system pressure signal reaches a set overflow pressure, if a proximity switch signal that the scraping plate is in place is received at the same time or first, judging that the scraping plate moves in place, and if the proximity switch signal that the scraping plate is in place is not received, judging that the scraping plate does not move in place;
s102, when the slide plate is in an ascending working condition, when the system pressure signal is monitored to reach the set overflow pressure, if a proximity switch signal that the slide plate is in the ascending position is received at the same time or first, the slide plate is judged to be in the position, and if the proximity switch signal that the slide plate is in the ascending position is not received, the slide plate is judged not to be in the position.
In order to solve the problem of garbage blockage in the filling device, a brand new press filling circulation control logic is provided to realize automatic identification and automatically control press filling actions (hereinafter referred to as program control repair scraping (ascending).
In the press filling circulation, the scraper is scraped in place, and when the sliding plate moves upwards in place, the system pressure is consistent with the pressure on the pressure oil pipeline of the multi-way valve reversing valve 7.
In the embodiment, a pressure signal SP of the system, a proximity switch signal G1 of the slide plate in the upward position and a proximity switch signal G2 of the scraper in the scraping position are monitored in real time by a pressure transmitter 9 externally connected to an oil pressure pipeline of an electric control system and a multi-way reversing valve 10, so that stroke control and scraping supplement (upward) are carried out.
Taking scraper scraping as an example, when the electric control system controller shows that the working condition of scraper scraping is adopted, when the system pressure signal SP is monitored to reach the overflow pressure of the multi-way reversing valve 10, the time of the system pressure signal SP is compared with the time of the proximity switch signal G2 in place with the scraper scraping to judge whether the scraping needs to be supplemented or not:
the time length when the system pressure signal SP of the pressure transmitter 9 is received and reaches the relief pressure is delta t1During the scraping process, if the proximity switch signal G2 for scraping the scraper is received at the same time or first, the scraper is defaulted to be in place at the moment, the scraping industry is normal, and the advance control and the supplementary scraping are not needed.
On the contrary, when the system pressure signal SP reaches the relief pressure of the multi-way directional control valve 10, the time duration is Δ t1And if the approach switch signal G2 that the scraper is in place in the scraping mode is not received, the situation that the scraper cannot be in place in the scraping mode due to excessive garbage in the filling device is considered, the scraping operation is abnormal, program control repairing scraping is conducted, and normal operation of the scraper is guaranteed.
When the condition that the stroke is needed to be controlled for scraping is judged, the vertical horse performs one-time action reverse rotation, namely the electromagnet Yv6 of the multi-way reversing valve 10 is controlled to be electrified, the scraper oil cylinder 5 retracts, the scraper is opened in place, the proximity switch G3 with the scraper opened in place sends a signal, the electromagnet Yv4 is electrified, the sliding plate oil cylinder 4 extends out, the sliding plate moves upwards in place and the proximity switch G1 sends a signal, the electromagnet Yv3 is electrified, the sliding plate oil cylinder 4 retracts, the sliding plate moves downwards, the electrifying duration of the electromagnet Yv3 is (delta t-delta t)2*n1) Second, wherein, delta t is the down-in-place time of the slide plate oil cylinder, delta t2Reduced down time, n, for a set single determination of a filling cycle anomaly1For continuously judging the number of times of abnormal filling operation), when the electromagnet Yv3 is powered off, the electromagnet Yv5 is powered on, the scraper oil cylinder 5 is extended out, the scraper is scraped, and the normal filling operation is executedAnd (6) operating. At this time, if it is monitored that the system pressure signal SP reaches the relief pressure of the multi-way directional control valve 10 for a period of time Δ t1And then, if the approach switch signal G2 that the scraper is in the scraping position is not received, executing the program-controlled scraping supplement operation again until the time length of the approach switch signal G2 that the scraper is in the scraping position before the monitored system pressure signal SP reaches the overflow pressure of the multi-way reversing valve 10 is delta t1And stopping the program-controlled scraping supplement program and executing normal pressure filling circulation. The operation of scraping is mended to the process accuse, can guarantee that it is effective packing to pack each time.
Similarly, when the electronic control system indicates a slide up condition, the time period when the system pressure signal SP is monitored to reach the relief pressure of the multi-way reversing valve 10 is Δ t1Meanwhile, if a proximity switch signal G1 that the slide plate moves upwards in place is received at the same time or firstly, the slide plate is defaulted to move in place at the moment, the ascending operation is normal, and the ascending is not required to be controlled and compensated.
On the contrary, when the system pressure signal SP reaches the relief pressure of the multi-way directional control valve 10, the time duration is Δ t1Meanwhile, if the sliding plate in-place ascending proximity switch signal G1 is not received, the sliding plate cannot ascend in place due to excessive garbage in the filler or the blocking block 12 formed in the garbage bin, the sliding plate is abnormal in operation, program control supplement ascending is required, the specific control logic is similar to the program control supplement scraping process, and details are not repeated.
The above embodiment is mainly implemented by determining the time period Δ t for the system pressure signal SP to reach the relief pressure of the multi-way directional control valve 101When the pressure sensor is used, whether blockage occurs or not is determined according to the receiving sequence relation of a proximity switch signal G1 in place when a sliding plate ascends and a proximity switch signal G2 in place when the sliding plate is scraped, namely, only when the sliding plate and the sliding plate are in place, normal filling can be determined, when the system pressure reaches the overflow pressure, the sliding plate and the sliding plate do not move in place, clamping stagnation can be definitely determined in the pressing and filling action process of the sliding plate and the sliding plate due to the blockage, the embodiment is based on the principle, after the clamping stagnation is determined in the pressing and filling action process of the sliding plate and the sliding plate due to the blockage, reverse action is performed at once, the scraper and the sliding plate are controlled to move in a stroke or controlled to move upwards, and therefore the situation that the blockage occurs in the pressing and filling action process of the scraper and the sliding plate is controlled to be repaired is avoidedThe garbage in the filler is too much, the scraper sliding plate does not act in place, and the garbage can not be effectively filled.
In the preferred embodiment of the application, when the system pressure signal is monitored, the obtained system pressure signal is filtered, and the pressure instantaneous value of the hydraulic oil cylinder during emergency stop or reversing is filtered, so that a stable system pressure signal is obtained.
The embodiment can effectively solve the problem of invalid filling of the press filling circulation by performing targeted program control on two reasons of invalid filling, but because of the particularity of the hydraulic system, when the hydraulic oil cylinder is reversed, a hydraulic shock phenomenon (as shown in fig. 6) can occur, wherein in a coordinate graph, P represents pressure, and T represents time. When the hydraulic cylinder moves to time T1, a load is encountered, the pressure increases momentarily from P1, then falls back after Δ T seconds to form a steady pressure P2. The system pressure signal SP of the whole system is filtered by the control program, the influence of hydraulic impact on the whole control program is eliminated, the validity and the accuracy of pressure signal data are ensured, misjudgment and misoperation cannot occur in the whole control program, and the accuracy and the reliability of control are improved.
In the preferred embodiment of the present application, in the press-filling process, whether the scraper and the slide plate move in place is judged according to the relevant operation parameters of the hydraulic system, and the method specifically comprises the following steps:
s111, after the scraper scraping working condition lasts for a set duration, if the actually measured extension length of the scraper cylinder 5 is equal to the maximum extension length of the scraper cylinder 5, judging that the scraper moves in place, and if the actually measured extension length of the scraper cylinder 5 is not equal to the maximum extension length of the scraper cylinder 5, judging that the scraper does not move in place;
and S112, after the slide plate uplink working condition lasts for a set time, if the measured extension length of the slide plate oil cylinder 4 is equal to the maximum extension length of the slide plate oil cylinder 4, judging that the slide plate moves in place, and if the measured extension length of the slide plate oil cylinder 4 is not equal to the maximum extension length of the slide plate oil cylinder 4, judging that the slide plate does not move in place.
In order to solve the problem of garbage blockage in the filling device, another brand new press filling circulation control logic is provided in the embodiment to realize automatic identification and self control of press filling actions (hereinafter referred to as program control repair scraping (ascending).
In a press filling cycle, a scraper is scraped in place, when a slide plate moves upwards in place, a slide plate oil cylinder 4 and a scraper oil cylinder 5 are both completely extended, the completely extended length of the scraper oil cylinder 5 is set to be delta X, the completely retracted length is set to be delta X, and the completely extended time is set to be delta T1; the complete extension length of the slide plate oil cylinder 4 is delta Y, the complete retraction length is delta Y, and the complete extension time is delta T2。
The embodiment realizes the correction control when invalid filling occurs by adding the displacement sensors to the sliding plate oil cylinder 4 and the scraper plate oil cylinder 5 to monitor the stroke of the oil cylinders in real time, and ensures that the filling is valid filling every time.
Taking scraper scraping as an example, when the controller displays that the working condition is scraper scraping, the scraper cylinder 5 starts to extend, and the displacement sensor on the scraper cylinder 5 monitors the extending length of the scraper cylinder 5 in real time. The full extension length of the scraper oil cylinder 5 is delta X, and the full extension time is delta T1, so when the controller displays that the scraper working condition is at the moment (delta T1+ T1) seconds later (in order to ensure the data accuracy, the T1 time monitoring is added), the oil cylinder stroke delta X measured by the displacement sensor above the scraper oil cylinder 5 is measured1When compared with Δ X1When the scraping force is equal to delta X, the scraping work is normal, and the stroke control and the supplementary scraping are not needed.
When the controller displays that the scraper is scraped (delta T1+ T1), the displacement sensor on the scraper oil cylinder measures the stroke delta X of the scraper oil cylinder1When the scraping operation is not equal to delta X, the program judges that the scraping operation is abnormal, and program control scraping supplement is needed.
At the moment, the standing horse performs one-time action reversal, namely the electromagnet Yv6 is controlled to be electrified, the scraper oil cylinder 5 retracts, the scraper is opened in place, and the displacement sensor above the scraper oil cylinder 5 displays delta X1When delta x and Yv4 are electrified, the slide plate cylinder 4 extends, the slide plate moves upwards to the right position, and the slide plate cylinder 4 moves upwardsUpper displacement sensor display Δ Y1When the power is obtained, Yv3 is obtained for power time Delta T3The following were used:
according to the stroke delta Y and the complete extension time delta t of the slide plate oil cylinder 4, the method can be obtained
In the formula: v- -the downward speed of the slide plate cylinder.
Delta Y-full extension of slide plate cylinder
ΔY2Reducing the down length of the ram cylinder
n-continuously judging the number of abnormal filling operations
Electric power supply delta T of sliding plate oil cylinder 43After the second, the electromagnet Yv3 loses power, Yv5 gets power, the scraper oil cylinder 5 extends out, the scraper is scraped, and the normal filling operation is executed. If (delta T1+ T1) second later, the displacement sensor on the scraper oil cylinder 5 measures the stroke delta X of the scraper oil cylinder1Still not equal to Δ X, and again performing programmed scratch-off until Δ X is measured1When the value is equal to delta X, the program is terminated to complement scraping, and a normal action loop is executed.
When the controller shows that the slide plate runs up, the slide plate oil cylinder 4 extends out, and the displacement sensor above the slide plate oil cylinder 4 monitors the extending length delta Y of the slide plate oil cylinder 4 in real time1When the controller displays the slide plate up working condition (delta T) at the moment2+ T1) second later (to ensure data accuracy, increase T1 second time monitoring), when Δ Y1When the sliding plate works normally, and the sliding plate does not need to be advanced to control and supplement to move upwards.
When the controller displays the slide plate to go upwards (delta T)2+ T1) second, the displacement sensor on the skateboard cylinder 4 measures the stroke delta Y of the skateboard cylinder 41When the sliding plate is not equal to delta Y, the program judges that the operation of the sliding plate is abnormal, the stroke control and compensation are needed to be carried out, the control logic is consistent with the program control and compensation scraping, and the description is omitted.
As shown in fig. 4, in a preferred embodiment of the present application, the compression truck press-filling control method further includes the steps of:
and S3, if the number n of times of controlling the reverse rotation of the scraper oil cylinder and the slide plate oil cylinder is larger than a set threshold value, controlling the rodless cavity oil of the push shovel oil cylinder 7 to flow back to the oil tank through the electromagnetic directional valve 6, and enabling the push shovel oil cylinder 7 to retract to drive the push shovel to retreat for a certain distance.
After the program continuously executes the stroke control compensation to move upwards for n times, if the pressure signal SP is still earlier than the sliding plate upwards-to-position proximity switch signal G1, or the controller displays that the sliding plate moves upwards (delta T)2+ T1) second, the displacement sensor on the ram cylinder 4 measures the stroke Delta Y of the ram cylinder 41When the distance is not equal to delta Y, the sliding plate cannot go upwards due to the fact that the garbage in the garbage can 3 forms a blocking block, and at the moment, the pushing shovel is controlled to go backwards by a program (hereinafter referred to as program control pushing shovel).
Aiming at the situation that the common garbage 11 in the garbage can 3 is blocked to form a blocking block 12 (see figure 5), the sliding plate cannot move upwards in place, so that the garbage can not be effectively filled. In the embodiment, an electromagnetic directional valve 6 and a control logic corresponding to the electromagnetic directional valve are added to a rodless cavity of a push shovel oil cylinder 7 of a hydraulic system.
The electromagnetic directional valve 6 of the embodiment is a normally closed type and is arranged on a rodless cavity pipeline of the push shovel oil cylinder 7. When the filling operation working condition is normal, the electromagnetic directional valve 6 does not need to work. And when the program continuously executes the program control compensation ascending for n times and still can not be effectively filled, executing the program control compensation retreating shovel. Namely, the electromagnet Yv7 is electrified, the electromagnetic directional valve 6 is opened, the rodless cavity oil of the push shovel oil cylinder 7 directly flows back to the oil tank through the electromagnetic directional valve 6 without passing through the push shovel valve 8, the push shovel oil cylinder 7 retracts, and the push shovel 2 returns. And when the program judges that the filling operation is normal through the comparison signal, the electromagnet Yv7 loses power. After the push shovel 2 retreats through program control, the slide pressure no longer reduces because the push shovel valve 8 is opened, the push shovel hydro-cylinder 7 contracts one section of contracting to can promote the jam block 12 through lasting high pressure, solve and form in the dustbin 3 and lead to the fact the problem that can't effectively load rubbish, guarantee slide normal operation.

and the dustbin anti-blocking control module is used for controlling the rodless cavity oil liquid of the push shovel oil cylinder 2 to flow back to the oil tank if the number n of times of controlling the reverse rotation of the actions of the scraper oil cylinder 5 and the sliding plate oil cylinder 4 is greater than a set threshold value, so that the push shovel oil cylinder 7 retracts to drive the push shovel 2 to retreat for a certain distance.
