Description

[Technical field]

[0001] The present invention relates to a concrete distributor and a concrete pouring system equipped with the same. [Background technology]

[0002] Conventionally, concrete pouring work is carried out when constructing concrete structures such as buildings and bridge piers. In concrete pouring work, a mixer truck that transports ready mixed concrete produced in a plant to a construction site, a concrete pump that sends the ready mixed concrete from the mixer truck through a pressure pipe to a concrete pouring location such as a high place, and a distributor that supports the pressure pipe and moves the nozzle of the pressure pipe to a desired position by rotating and raising and lowering a boom (see, for example, Patent Documents 1 and 2), etc. are used, and many workers (for example, mixer truck operators, receiving inspectors, pump operators, nozzle operators, etc.) are engaged in these operations.

[0003] In addition, many documents are prepared at each stage of the concrete pouring work, such as concrete order forms, pouring plans (reports), ready-mix concrete delivery slips, and settlement slips. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2022-146335 A [Patent Document 2] Japanese Patent Application Publication No. 7-207941 Summary of the Invention [Problem to be solved by the invention]

[0005] However, the number of construction workers in Japan is on the decline, and there is a demand for more efficient construction and labor saving. However, conventional concrete pouring work has the following problems:

[0006] First, the problem is that the concrete pouring progress is recorded in analog. For example, the concrete pouring progress (how many meters at what time) 3 The construction supervisor would handwrite notes in a field notebook, such as the date of pouring, where the concrete was poured, etc., and then create a pouring report based on the contents of the notes after pouring. This method is time-consuming and has the risk of recording errors such as omissions and misprinting.

[0007] In addition, wasteful personnel allocation is also an issue. For example, to move the nozzle of the pressure pipe to the desired casting position, as shown in Figure 6, one to three nozzle operators must carry, pull, or drag the nozzle, which may result in wasteful personnel allocation.

[0008] Another problem is that documents and other information are basically paper-based and not digitized.

[0009] The present invention has been made in consideration of the above, and aims to provide a concrete distributor that can improve the efficiency and reduce the labor required for concrete pouring work, and a concrete pouring system equipped with the same. [Means for solving the problem]

[0010] In order to solve the above-mentioned problems and achieve the object, the concrete distributor of the present invention is a concrete distributor that comprises a boom supported on a base so that its posture can be changed, and a pressure pipe provided along the boom, and supplies ready-mixed concrete pressure-fed by a concrete pump through the pressure pipe to a concrete pouring location, and is characterized in that it comprises a data collection unit that collects data indicating the position of the discharge outlet of the pressure pipe or the position of the tip of the boom in real time, a pouring position calculation unit that calculates a pouring position for a specified period of time at the concrete pouring location based on the data, and a recording unit that records the calculated pouring position.

[0011] In addition, another concrete distributor according to the present invention is characterized in that, in the above-mentioned invention, it further includes a user position detection unit that detects the position of a user in the vicinity of the discharge port of the pressure pipe, and a control unit that controls the boom so that the discharge port of the pressure pipe tracks the detected position.

[0012] In addition, another concrete distributor according to the present invention is characterized in that, in the above-mentioned invention, it further includes a failure detection unit that detects or predicts a failure of the boom or the pressure pipe, and a failure notification unit that notifies a user when the failure is detected or predicted.

[0013] In addition, the concrete pouring system of the present invention is a system for pouring concrete, and is characterized by comprising a concrete pump having an IoT function and the above-mentioned concrete distributor. Effect of the Invention

[0014] According to the concrete distributor of the present invention, the concrete distributor is provided with a boom supported on a base so that its posture can be changed, and a pressure pipe provided along the boom, and supplies ready mixed concrete pumped by a concrete pump through the pressure pipe to a concrete pouring location. The concrete distributor is provided with a data collection unit that collects data indicating the position of the discharge port of the pressure pipe or the tip position of the boom in real time, a pouring position calculation unit that calculates the pouring position at the concrete pouring location for a predetermined period based on the data, and a recording unit that records the calculated pouring position, so that the pouring progress can be confirmed in real time. In addition, the number of personnel required for identifying and recording the pouring position can be reduced. Therefore, the effect of improving the efficiency of concrete pouring work and reducing manpower is achieved.

[0015] In addition, another concrete distributor according to the present invention further includes a user position detection unit that detects the position of a user near the discharge outlet of the pressure pipe, and a control unit that controls the boom so that the discharge outlet of the pressure pipe tracks the detected position, thereby achieving the effect of reducing the number of personnel required to relocate the discharge outlet of the pressure pipe.

[0016] In addition, another concrete distributor of the present invention further includes a failure detection unit that detects or predicts a failure of the boom or the pressure pipe, and a failure notification unit that notifies the user when the failure is detected or predicted, thereby achieving the effect of enabling a rapid response to the failure.

[0017] In addition, according to the concrete pouring system of the present invention, which is a system for pouring concrete, it is equipped with a concrete pump having an IoT function and the above-mentioned concrete distributor, and therefore by linking data regarding the pouring quantity obtained from the concrete pump and data regarding the pouring position obtained from the concrete distributor, it is possible to record in association with the pouring position at the concrete pouring location the pouring quantity.

[0019] Hereinafter, an embodiment of a concrete distributor and a concrete pouring system including the same according to the present invention will be described in detail with reference to the drawings. Note that the present invention is not limited to the embodiment.

[0020] As shown in Figure 1, a concrete pouring system 10 according to an embodiment of the present invention includes a concrete distributor 12 having an IoT (Internet of things) function, a concrete pump 14 having an IoT function, a mixer truck 16 having an IoT function, an information management server 18, and a terminal 22 (e.g., a mobile terminal) carried by a user P (a concrete pourer) at a concrete pouring site 20.

[0021] (Concrete Distributor) The concrete distributor 12 comprises a boom 26 supported in such a manner that its posture can be changed on the top of a columnar base 24 arranged around the concrete pouring location 20, and a pressure pipe 28 provided along the boom 26, and supplies ready-mixed concrete pumped through a pressure pipe 30 of the concrete pump 14 to the concrete pouring location 20. The boom 26 has a plurality of joints 32, an arm 34, and an actuator (not shown) for driving these, and is configured to be freely rotatable around a vertical axis relative to the base 24 and freely rotatable at the joints 32.

[0022] This concrete distributor 12 has an IoT function and is equipped with a control unit 36 ​​that controls the posture of the boom 26, a data collection unit 40 that collects data indicating the operating status of the concrete distributor 12 in real time, a pouring position calculation unit 42, a recording unit 44 that records the calculated pouring position, a user position detection unit 46, a fault detection unit 48, and a fault notification unit 50.

[0023] The control unit 36 ​​can check the control and perform a predetermined remote operation on the user's terminal 22 at the concrete pouring location 20. For example, the attitude of the boom 26 can be controlled. The control unit 36 ​​can also control the boom 26 so that the outlet 38 of the flexible hose tracks the position of the user P detected by the user position detection unit 46. This allows the boom 26 to be moved so as to follow the vicinity of the user P during concrete pouring. This allows the number of personnel required to relocate the outlet 38 of the pressure pipe 28 to be reduced.

[0024] The data collection unit 40 is connected to the information management server 18 via a communication line 52. The data collection unit 40 is an IoT device, and transmits measurement data output from various sensors to the information management server 18 by linking the measurement data with the measurement time. For example, the data collection unit 40 identifies the center position of the boom 26 using a GPS function, and calculates and transmits data indicating the position of the discharge port 38 of the flexible hose or the tip position of the boom 26 based on the control information of the joint 32. The data collection unit 40 also transmits data indicating a fault signal of the concrete distributor 12. The communication line 52 can use, for example, a short-distance wireless communication method such as Wi-Fi (registered trademark). The data transmitted to the information management server 18 can be checked in real time from the user's terminal 22.

[0025] The pouring position calculation unit 42 calculates the pouring position for a predetermined period at the concrete pouring site 20 based on the data collected by the data collection unit 40. For example, based on the position of the discharge port 38 of the flexible hose or the tip position of the boom 26 calculated by the data collection unit 40, it calculates what time and where concrete was poured.

[0026] The recording unit 44 records the pouring position calculated by the pouring position calculation unit 42. The recorded pouring position is transmitted to the information management server 18 and can be confirmed in real time from the user's terminal 22. Figure 2 shows an example of the pouring position output on the user's terminal 22.

[0027] The user position detection unit 46 detects the position of the user P near the outlet 38 of the flexible hose at the tip of the pressure pipe 28. The position of the user P may be detected, for example, by a helmet 54 worn by the user P. This helmet 54 is an IoT device and is equipped with various sensors. The user position detection unit 46 identifies the position of the helmet 54 based on the output values ​​of various sensors such as a beacon and GPS equipped in the helmet 54, and sets this position as the position of the user P. Note that the position may be detected based on GPS information of the terminal 22 carried by the user P without using the helmet 54, or the position of the user P may be detected using an image recognition function of a camera installed in the concrete distributor 12 or the like.

[0028] The failure detection unit 48 detects or predicts failure of the boom 26 or the pressure pipe 28. The failure detection unit 48 includes various sensors that detect the wear state, vibration, pressure, sound, etc. of the pipes such as the boom 26 and the pressure pipe 28, and a memory that records the output signals of the sensors, and detects or predicts a failure when the output signal of the sensor is an abnormal signal. The failure detection unit 48 can also detect a failure based on the failure signal collected by the data collection unit 40.

[0029] The fault notification unit 50 notifies the user by outputting a warning light or a warning alarm when the fault detection unit 48 detects or predicts a fault. The warning light or warning alarm may be output directly from the concrete distributor 12, or may be notified by outputting the status of the concrete distributor 12 to the information management server 18 or the user's terminal 22. Fig. 3 shows an example of output of the status of the concrete distributor 12 on the user's terminal 22.

[0030] According to the concrete distributor 12 of this embodiment, the user can check the data on the information management server 18 from the terminal 22 on the user side, thereby checking the concrete pouring progress in real time. In addition, the number of personnel required for identifying and recording the concrete pouring positions can be reduced. It may be possible to output a concrete pouring report based on the concrete pouring performance data recorded in the information management server 18. In this way, it becomes possible to digitize the documents, and the effort required for creating the documents can be reduced.

[0031] In addition, by controlling the boom 26 so that the discharge port 38 of the flexible hose tracks the position of the user P, the worker can easily cast the concrete without dragging the discharge port 38 of the flexible hose. This reduces the number of personnel required to relocate the discharge port 38. This makes it possible to improve the efficiency of concrete casting work and reduce the number of personnel required. In addition, it is possible to quickly respond to malfunctions.

[0032] (Concrete Pump) The concrete pump 14 includes a hopper 56 for storing fresh concrete, a pump body 58 connected to the hopper 56, a pressure pipe 30 connected to the pump body 58, legs 60 for supporting the hopper 56 and the pump body 58, and wheels 62. The legs 60 are extendable, and the concrete pump 14 can be moved by connecting a towing vehicle (not shown), but may also be a self-propelled four-wheeled structure. A cylinder piston device (not shown) is provided inside the pump body 58, and the operation of this device discharges the fresh concrete in the hopper 56 into the pressure pipe 30. The fresh concrete can be pressure-fed to a remote concrete casting location 20 through the pressure pipe 30 and the pressure pipe 28 of the concrete distributor 12. The concrete pump 14 is operated unmanned, and the work of pouring fresh concrete into the hopper 56 is performed by a mixer truck operator Q.

[0033] This concrete pump 14 is equipped with a control unit 64 that controls the concrete pump 14, a data collection unit 66 that collects data indicating the operating status of the concrete pump 14 (discharge volume, pumping pressure, fault signals, etc.) in real time, a pouring quantity calculation unit 68 that calculates the pouring quantity based on the data, a recording unit 70 that records the calculated pouring quantity, a fault detection unit 72, a fault notification unit 74, a position detection unit 76, an anti-theft unit 78, a drive stop unit 80, and an AI (Artificial Intelligence) camera 82.

[0034] The control unit 64 can check the control and perform predetermined remote operations on the user's terminal 22 at the concrete pouring site 20. For example, it is possible to stop and restart the pump function, adjust the discharge volume, and perform other operations. This eliminates the need for communication to check and adjust the pump discharge volume, and can reduce the number of pump operator personnel conventionally stationed near the concrete pump 14.

[0035] The data collection unit 66 is connected to the information management server 18 via the communication line 52. The data collection unit 66 is a so-called IoT device, and transmits measurement data (discharge amount, pumping pressure, failure signal, etc.) output from various sensors to the information management server 18 in association with the measurement time. The data transmitted to the information management server 18 can be checked in real time from the user's terminal 22.

[0036] The pouring quantity calculation unit 68 calculates the quantity of concrete poured in a predetermined period at the concrete pouring site 20 based on the data collected by the data collection unit 66. For example, 3 You can calculate how many meters of concrete were poured by using the number of cylinder pistons, or by the time. 3 It is also possible to calculate whether the concrete has been poured.

[0037] The recording unit 70 records the concrete pouring quantity calculated by the concrete pouring quantity calculation unit 68. The recorded concrete pouring quantity is transmitted to the information management server 18 and can be checked in real time from the user's terminal 22. Figure 4 shows an example of the concrete pouring quantity output on the user's terminal.

[0038] The AI ​​camera 72 is a camera equipped with an AI algorithm, which captures images of the hopper 56 and mixer truck 16 and outputs signals to the information management server 18 and the user's terminal 22. The captured images include the flow status of the ready-mixed concrete into the hopper 56, the license plate of the mixer truck 16, the working status of the mixer truck 16, etc. Therefore, it is possible to check the status near the hopper 56 on the user's terminal 22 at the concrete pouring location 20. Note that while the area around the concrete pump 12 is operated unmanned, a microphone for communication may be provided near the hopper 56 and used for conversation between the mixer truck operator Q and the concrete pourer (user P).

[0039] The information management server 18 performs image recognition processing on the signal output from the AI ​​camera 72 to determine and record data such as the vehicle number written on the license plate of the mixer truck 16, the work status of the mixer truck 16 (for example, no mixer truck / arrival / waiting / start pouring / pouring / end of pouring), the cumulative number of mixer trucks 16 since the start of pouring, and the cumulative input quantity. The recorded data can be checked in real time from the user's terminal 22. FIG. 5 shows an example of the output of the status of the mixer truck 16 on the user's terminal 22. The information management server 18 may also record the mix information of the ready-mixed concrete loaded on the mixer truck 16, the test results in the plant, the mixing time of the ready-mixed concrete, the shipping time, the vehicle number of the mixer truck 16, and slip information (delivery information) by information linkage with a ready-mixed concrete plant. The slump value of the ready-mixed concrete may also be estimated based on environmental information such as humidity and temperature and an image of the flow status of the ready-mixed concrete into the hopper 24.

[0040] (Mixer truck) The mixer truck 16 transports ready mixed concrete loaded at the plant to the vicinity of the concrete pump 14 at a remote concrete pouring site 20. The mixer truck 16 has an IoT function, and transmits the current location detected by the GPS function, the mix information of the ready mixed concrete to be loaded, and the remaining amount of ready mixed concrete to the information management server 18 via the communication line 52.

[0041] In the above configuration, data on pouring quantity acquired from the concrete pump 14 and data on pouring position acquired from the concrete distributor 12 may be linked. In this way, the pouring quantity and pouring position at the concrete pouring site 20 can be recorded and output in association with each other. In addition, data acquired from the plant and mixer truck 16 (mixture information of ready-mixed concrete, etc.) may be linked. In this way, more detailed pouring results can be recorded and output.

[0042] In addition, by setting the pouring range in advance, the pouring route and pouring quantity can be calculated, and the boom 26 can be controlled along the calculated pouring route, while the discharge volume and pumping pressure of the concrete pump 14 can be controlled to provide an automatic driving function for automatic pouring.

[0043] As described above, the concrete distributor according to the present invention is a concrete distributor that includes a boom supported on a base so that its posture can be changed, and a pressure pipe provided along the boom, and supplies ready-mixed concrete pumped by a concrete pump through the pressure pipe to a concrete pouring location. The concrete distributor includes a data collection unit that collects data indicating the position of the discharge port of the pressure pipe or the tip position of the boom in real time, a pouring position calculation unit that calculates the pouring position at the concrete pouring location for a predetermined period based on the data, and a recording unit that records the calculated pouring position, so that the pouring progress can be confirmed in real time. In addition, the number of personnel required for calculating the pouring position can be reduced. Therefore, the efficiency of concrete pouring work can be improved and manpower can be saved.

[0044] In addition, another concrete distributor according to the present invention further includes a user position detection unit that detects the position of a user near the discharge outlet of the pressure pipe, and a control unit that controls the boom so that the discharge outlet of the pressure pipe tracks the detected position, thereby reducing the number of personnel required to relocate the discharge outlet of the pressure pipe.

[0045] In addition, according to another concrete distributor of the present invention, it further includes a failure detection unit that detects or predicts a failure of the boom or the pressure pipe, and a failure notification unit that notifies the user when the failure is detected or predicted, so that a response to the failure can be made quickly.

[0046] In addition, according to the concrete pouring system of the present invention, which is a system for pouring concrete, the system is equipped with a concrete pump having an IoT function and the above-mentioned concrete distributor, so that by linking data regarding the pouring quantity obtained from the concrete pump and data regarding the pouring position obtained from the concrete distributor, the pouring position at the concrete pouring location can be associated and recorded with the pouring quantity.

[0047] The "Sustainable Development Goals (SDGs)" are 17 international goals that were adopted at the United Nations Summit in September 2015. The concrete distributor according to this embodiment and a concrete pouring system equipped with the distributor can contribute to achieving one of the 17 SDGs, for example goal 7, "Affordable and Clean Energy for All." [Industrial Applicability]

[0048] As described above, the concrete distributor of the present invention and the concrete pouring system equipped with the same are useful for concrete pouring work, and are particularly suitable for achieving efficiency and labor savings in concrete pouring work. [Explanation of symbols]
