Description

Technical Field

[0001] The invention relates to the technical field of concrete pump trucks, and in particular to an operation status monitoring system and method based on a concrete pump truck. Background Art

[0002] Concrete pump trucks are mainly used in the construction process to transport concrete transported by concrete trucks to the location of building columns and piles to complete the concrete pouring work.

[0003] During pouring, the S-type valve is controlled to switch between the two feeding barrels. When the S-type valve is separated from the feeding barrel, the S-type valve is matched with another feeding barrel. The feeding barrel separated from the S-type valve sucks concrete through the high-pressure plunger pump. Correspondingly, the other high-pressure plunger pump pushes the concrete inside the feeding barrel into the discharge pipe through the S-type valve. By reciprocatingly switching the S-type valve and the high-pressure plunger pump, the concrete inside the hopper is continuously delivered to the building column position through the delivery pipe.

[0004] During pile foundation construction, in order to ensure the quality requirements of each pile foundation, there are certain requirements for the pouring volume of each concrete pile foundation. It is necessary to ensure that each poured pile foundation reaches a rough theoretical amount. Therefore, it is necessary to monitor the pouring volume of concrete by the concrete pump truck during construction to ensure that the quality of each concrete pile foundation meets the standards.

[0005] However, the existing concrete pump volume monitoring calculates the total pouring volume by calculating the transportation volume of the concrete truck, which is not able to accurately monitor a single building pile foundation, resulting in only overall monitoring but not single monitoring, which affects the qualification rate of the building pile foundation. Therefore, the existing concrete pump truck needs a real-time operation status monitoring system to perform real-time monitoring of the concrete pump truck's pump volume. Summary of the invention

DETAILED DESCRIPTION

[0055] In order to enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0056] Embodiment 1

[0057] See also Figure 1 - Figure 7 , an operation status monitoring system based on a concrete pump truck, comprising a pumping control module, a data terminal and a pumping monitoring module;

[0058] The pumping monitoring module is used to connect various status monitoring sensors of the concrete pump truck with signals;

[0059] The data terminal includes a data processor, a data display screen and a control button installed inside the concrete pump truck. The data terminal is used to receive monitoring data from the pumping monitoring module and process the data to determine the operating status of the concrete pump truck;

[0060] The pumping control module is used for signal connection with the power system of the concrete pump truck, for receiving and transmitting the pumping instructions of the data terminal, and for controlling the concrete pump truck to perform the concrete pumping work.

[0061] In an optional embodiment, the method further includes a hopper 1 installed on the body of a concrete pump truck, wherein two feeding barrels 2 are fixedly connected to the outside of the hopper 1, and high-pressure plunger pumps 3 are arranged on the outside of the two feeding barrels 2. A discharge pipe 4 is fixedly connected to the side of the hopper 1 away from the feeding barrels 2, and an S-type valve 5 is rotatably connected to the inner end of the discharge pipe 4. The movable end of the S-type valve 5 is alternately covered on the outside of the pipe mouth of the feeding barrel 2, and a swing hydraulic pump 6 for driving the S-type valve 5 is arranged on the outside of the S-type valve 5.

[0062] It should be noted that during the operation of the concrete pump truck, the two high-pressure plunger pumps 3 are respectively connected to a pumping piston, which slides inside the feeding barrel 2. Under the action of the high-pressure plunger pump 3, the two pumping pistons move alternately, one moving forward while the other moves backward.

[0063] During the pumping process, the internal pumping piston of the feeding barrel 2 connected to the S-type valve 5 moves forward, and the internal pumping piston of the feeding barrel 2 separated from the S-type valve 5 moves backward.

[0064] When the pumping piston retreats, the pumping piston absorbs concrete inside the hopper 1 through the feeding barrel 2. At the same time, when the pumping piston moves forward, the pumping piston pushes the pumping material inside the feeding barrel 2 into the discharge pipe 4 through the S-type valve 5.

[0065] When the S-type valve 5 is switched, the high-pressure plunger pump 3 controls the pumping piston to move in the reverse direction, and similarly, the above actions are repeated to complete the pumping of concrete, so that the concrete continuously passes through the discharge pipe 4 and is then output to the building pile foundation position through the delivery pipe.

[0066] In an optional embodiment, it also includes a feed pipe 7, which is connected to the discharge pipe 4 through a feeding pipe, the feed pipe 7 is located at the end of the feeding pipe, and the inside of the feed pipe 7 is rotatably connected to a double-flap valve 8. The feed pipe 7 is located below the double-flap valve 8 and is movably connected to a feeding barrel 9. The feed pipe 7 is located below the feeding barrel 9 and is provided with a valve port 10. The feed pipe 7 is located below the valve port 10 and is rotatably connected to a material blocking valve plate 11. The side of the feed pipe 7 is fixedly connected to a valve plate chamber 12 for accommodating the material blocking valve plate 11, and the bottom of the valve plate chamber 12 is tilted downward.

[0067] It should be noted that the feed pipe 7 is located at the end of the conveying pipe, and the concrete slurry falls to the building pile foundation position through the feed pipe 7.

[0068] The double flap valve 8 and the material stop valve plate 11 are alternately opened. In the initial state, the material stop valve plate 11 is in a closed state and the double flap valve 8 is in an open state. When the double flap valve 8 is closed, the material stop valve plate 11 is opened; at the same time, after the material stop valve plate 11 is closed, the double flap valve 8 is opened.

[0069] Repeat the above alternating work to make the concrete slurry fall downward evenly, thereby avoiding random discharge of the concrete slurry. Through the cooperation of the double-flap valve 8 and the material-blocking valve plate 11, the concrete slurry can fall downward intermittently and quantitatively, thereby effectively ensuring the uniformity and stability of the discharge of the concrete slurry, facilitating the concrete pouring work of the construction, and effectively ensuring the stability of the concrete pouring of the construction.

[0070] Specifically, when the concrete slurry falls onto the material-blocking valve plate 11 and the material-blocking valve plate 11 carries a certain amount of concrete slurry, the double-flap valve 8 is closed. When the double-flap valve 8 is completely closed, the material-blocking valve plate 11 is opened. At this time, the concrete slurry between the material-blocking valve plate 11 and the double-flap valve 8 falls downward, completing the pouring of the slurry.

[0071] When the concrete slurry between the material-blocking valve plate 11 and the double-flap valve 8 is completely poured, the material-blocking valve plate 11 is controlled to be closed. When the material-blocking valve plate 11 is completely closed, the double-flap valve 8 is opened again to allow the concrete slurry on the top of the double-flap valve 8 to fall to the top of the material-blocking valve plate 11.

[0072] By repeating the above steps, intermittent stable pouring of concrete is completed.

[0073] In an optional embodiment, a first pressure-sensitive weighing device 111 is fixedly connected above the material-blocking valve plate 11 , and a second pressure-sensitive weighing device 112 is fixedly connected below the material-blocking valve plate 11 .

[0074] It should be noted that the first pressure-sensitive weighing device 111 is used to detect the weight of the concrete slurry on the top of the material-blocking valve plate 11. When the double-flap valve 8 is closed, the measurement value of the first pressure-sensitive weighing device 111 is detected, and the volume of the concrete on the top of the material-blocking valve plate 11 is predicted based on the density of the concrete. Therefore, when the material-blocking valve plate 11 is opened, the estimated weight and volume of the slurry that falls this time can be recorded.

[0075] Since it is intermittent quantitative pouring, the weight is recorded several times and the pouring amount of a single pile foundation is recorded according to the number of pouring times of a single pile foundation under construction, so as to ensure the accuracy of pouring each pile foundation and ensure the quality of building construction.

[0076] At the same time, the second pressure-sensitive weighing device 112 is used to detect the amount of concrete at the bottom of the material-blocking valve plate 11 when the material-blocking valve plate 11 is opened. When the pipe mouth of the lower feeding pipe 7 is blocked, concrete accumulates under the material-blocking valve plate 11. Therefore, when the second pressure-sensitive weighing device 112 detects pressure and when the pressure value is greater than the set safety value, it can be judged that the inside of the lower feeding pipe 7 is blocked, thereby facilitating early warning and ensuring the stability and safety of the pump truck when pumping concrete.

[0077] refer to Figure 4 and Figure 5, in an optional embodiment, the pumping monitoring module includes a theoretical quantity monitoring module and an actual quantity monitoring module;

[0078] The theoretical quantity monitoring module includes a counting unit and a statistical unit. The counting unit is connected to the high-pressure plunger pump 3 by signal. The counting unit is used to record the number of feeding times of the feeding barrel 2. The statistical unit is used to receive the recorded data of the counting unit and calculate the theoretical pumping quantity.

[0079] The counting unit is also used to be electrically connected to the first pressure-sensitive weighing device 111, the second pressure-sensitive weighing device 112 and the driving assembly of the material-blocking valve plate 11, and is used to count the number of times the material-blocking valve plate 11 is opened and closed, and to record the single pumping mass of the first pressure-sensitive weighing device 111. The statistical unit is used to receive the recorded data of the counting unit and calculate the actual pumping amount.

[0080] refer to Figure 4 and Figure 6 ,In an optional embodiment, the data terminal includes a human-computer interaction module, a data processing module and an early warning module;

[0081] The human-machine interaction module is electrically connected to the data display touch screen and the operation buttons, and is used for information display or input of operation instructions. The human-machine interaction module is the control terminal of the concrete pump truck;

[0082] The data processing module is used to process the pump truck control data and the monitoring data of the pumping monitoring module;

[0083] The early warning module is connected to the data processing module by signal, and is used to receive the output result of the data processing module and make judgments based on the output result. When the output result is "abnormal", the early warning module issues an early warning message. The early warning mode includes sound warning or light warning.

[0084] It should be noted that, through the coordinated use of the theoretical quantity monitoring module and the actual quantity monitoring module, when the difference between the calculated theoretical quantity monitoring module and the actual quantity monitoring module is greater than or equal to the system preset pump quantity safety threshold, it means that the pumping material of the feeding barrel 2 has not reached the preset pumping value, and then it is judged that the delivery pipe of the pump truck is blocked or the feeding barrel 2 is damaged, so that the delivery slurry amount of the feeding barrel 2 is not equal to the actual output of the discharge pipe 7. At the same time, the data processing module transmits the early warning signal to the early warning module, and the early warning module issues an early warning, thereby reminding the staff to conduct actual inspection and maintenance, thereby ensuring the working stability of the pump truck.

[0085] At the same time, through the coordinated use of the theoretical quantity monitoring module and the actual quantity monitoring module, double-layer detection of the pumping process of the pump truck is carried out, thereby effectively improving the monitoring effect of the pumped material, and then facilitating the control of the pouring volume of a single building pile foundation, facilitating the monitoring of the pumped material from the whole to the zero of the building pile foundation, and effectively improving the pouring quality of the building pile foundation.

[0086] refer to Figure 4 and Figure 7 , in an optional embodiment, the pumping control module includes a power execution module, a data acquisition module and a drive adjustment module;

[0087] The power execution module is used to be electrically connected to the high-pressure plunger pump 3 and the swing hydraulic pump 6, and is used to control the S-type valve 5 to switch back and forth between the two pipe openings of the feeding barrel 2, and is also used to control the swing hydraulic pump 6 to drive the swing of the S-type valve 5;

[0088] The power execution module is also used to be electrically connected to the driving components of the double-flap valve 8 and the material-blocking valve plate 11, and is used to control the opening and closing of the double-flap valve 8 and the material-blocking valve plate 11 through the driving components;

[0089] The data acquisition module is connected to the power execution module, and the data acquisition module collects the action control frequency information of the high-pressure plunger pump 3 and the swing hydraulic pump 6, as well as the closing time and driving response information of the driving components of the double flap valve 8 and the material blocking valve plate 11;

[0090] The drive adjustment module is used to balance the data acquisition module and the power execution module, to control the synchronous alternating operation of the high-pressure plunger pump 3 and the S-type valve 5, and to control the alternating opening and closing of the double-flap valve 8 and the material blocking valve plate 11.

[0091] In an optional embodiment, the early warning module is connected to the second pressure-sensitive weighing device 112 by signal, and the pressure information of the second pressure-sensitive weighing device 112 is transmitted to the early warning module. The early warning module system sets a port pressure early warning value. When the pressure of the second pressure-sensitive weighing device 112 is not less than the port pressure early warning value set by the system, the early warning module issues an early warning message to further improve the safety of the device.
