Specifically, the present invention is a pile driver and excavation that press-fits a construction member such as a steel pipe pile or a hollow rod into the ground by an auger that moves up and down along a leader. The present invention relates to a construction management device for an earth drill that forms a pile hole by pushing it into the ground while rotating a keriba equipped with the device.

Conventionally, construction machines such as large pile drivers and earth drills have been used at construction sites where steel pipe piles are buried and ground is improved. Heavy objects such as booms are removed and transported separately from the base machine (see, for example, Patent Document 1). In addition, in order to reduce transportation costs and smoothly respond to the diversification of pile driving sites, the leader can be disassembled into multiple leader members with a length suitable for transportation, and the length of the leader can be standardized. A method for efficiently recombining with a short specification has been developed (see, for example, Patent Document 2). Further, a method for attaching / detaching a working device such as an auger to / from a reader and a jig for supporting them have also been developed (see, for example, Patent Document 3).

On the other hand, such a construction machine is equipped with a construction management device that stores a construction management program for controlling various construction methods. When a construction member such as a steel pipe pile or a hollow rod is press-fitted into the ground, this construction management device executes a construction management program by a control device (control box) provided in the cab, and various types such as leaders and augers. Each data is obtained from a plurality of sensors provided in the component, for example, a depth sensor using an encoder, a torque sensor that detects the torque of the auger by pressure or current, a rotation sensor that detects the rotation pulse of the auger, and the like. , Depth, speed, torque, rotation speed, etc. are calculated and displayed on the display, and the construction is performed while recording in the memory. As a result, the operator can grasp the operating state of each measurement site and input various information related to the construction by operating the touch panel based on the operating state (see, for example, Patent Document 4).

A control device 43 that executes a construction management program for constructing a ready-made pile construction method, a cast-in-place pile construction method, or a ground improvement construction method based on a detection signal from the means 42 and information input by the operator, and a construction management program by the operator. It is composed of a touch panel type display 44 for confirming the processing result of the above and inputting data.

Further, a communication means using a network is provided between each detection means 42 and the control device 43. This communication means is a high-level communication line for performing communication using a communication method known as Industrial Ethernet (registered trademark, the same shall apply hereinafter), which is a hub of the high-level network, for example, a communication method using PROFINET (registered trademark, the same shall apply hereinafter). 45, a first relay device 46 (leader side relay device of the present invention), a second relay device 47 (auger side relay device of the present invention), and a third relay device, which are a plurality of relay devices connected to the upper communication line 45. It is composed of a relay device 48 and a switching hub 49, and a device communication line 50 for connecting the relay devices 46 to 48 and the detection means 42 by communication by IO-Link described later.

The control device 43 includes a CPU that performs various arithmetic processes, storage means such as RAM and FRASH ROM that stores various construction data and construction management programs, and switch upper communication having one end connected to the upper communication port 49a of the switching hub 49. It is provided with a hub-side interface 43a to which the other end of the wire 45a is connected. When the construction management program is executed by the arithmetic processing of the CPU, the construction data is created and displayed on the display 44 connected to the upper communication port 49b of the switching hub 49. Further, the control device 43 also includes USB interfaces 43b and 43c to which a communication device for printing and storing construction data is connected by a printer 51 as a printing means, a USB memory 52 as a storage means, or the like.

Each of the relay devices 46 to 48 is a box-shaped hub provided with a plurality of communication ports capable of relaying data between the upper network including the control device 43 and the detection means 42, and the first relay device 46 is a reader. A mounting seat in the middle portion of 15, specifically, on the lower side surface of the upper first member 24a, on the side surface of the auger 28 for the second relay device 47, and in the equipment room 20 of the upper swing body 13 for the third relay device 48. They are screwed together via (not shown). Then, the first upper communication line 45b is connected to the upper communication ports 49c and 46a of the switching hub 49 and the first relay device 46, and the second upper communication lines 45b are connected to the upper communication ports 46b and 47a of the first relay device 46 and the second relay device 47. The upper communication line 45c has a third upper communication line 45d at each upper communication port 49d and 48a of the switching hub 49 and the third relay device 48, and a switch upper communication line 45a between the switching hub 49 and the control device 43, respectively. By being connected, an upper network is configured, and each of the relay devices 46 to 48 operates as a slave of the control device 43.

Further, whether or not each of the relay devices 46 to 48 is in a state where an alarm should be made based on the state of the detection means 42 in a state where the relay devices 46 to 48 are connected to the corresponding upper communication lines 45a, 45b, 45c, 45d. It is equipped with device monitoring units 46c, 47b, and 48b that monitor and output monitoring output corresponding to the state when it is in a state to be alarmed. The state to be alarmed is the function of the detection means 42 because the construction management program cannot be executed normally due to a failure of the detection means 42, a disconnection or short circuit of the device communication line 50, disconnection to the communication port, or a connection error. And communication needs to be restored. For example, when the device communication line 50 is disconnected, signals in the disconnected state are output from the device monitoring units 46c, 47b, 48b of the corresponding relay devices 46 to 48 to the display 44 via the control device 43. Based on this output result, the operator identifies the failure location and the failure cause by the message displayed on the display 44.

The detection means 42 is a device to be controlled by the control device 43. As the detection means 42, an output system device and an input system device can be applied. Examples of the input system device include a proximity sensor and an operation switch, and examples of the output system device include an actuator and a motor. Further, a conversion means 53 for controlling a drive current of an actuator, a motor, or the like can also be used as a device. Since the detection means 42 and the conversion means 53 are attached to the reader 15, the auger 28, and the base machine 14, which are measurement sites, device communication is performed to the corresponding device communication ports of the relay devices 46 to 48 arranged in the vicinity thereof. Each is connected via the line 50, and communication by IO-Link is performed.

IO-Link is a relatively new sensor interface (device communication protocol) standardized in IEC61131-9 under the name "Single-drop digital communication interface for small sensors and actuators" (SDCI). A small sensor (detection means 42 of the present invention) or the like can be connected with a single cable (device communication line 50 of the present invention), and these information can be used as a hub function as an IO-Link master (each relay device 46 of the present invention). It can be integrated into a programmable controller (control device 43 of the present invention) via 48). Moreover, since power can be supplied with the same cable, wiring can be saved.

By using IO-Link, information other than the on / off signal (1 bit), for example, 32 bytes (256 bits) of numerical data can be acquired, so that the device ID, revision, serial number, etc. can be identified. Information and diagnostic information such as detection margin and internal temperature can be acquired. Therefore, the control unit of the IO-Link master (device monitoring unit 46c, 47b, 48b of the present invention) can handle this information, which is useful for investigating the cause of the defect, diagnosing the product life, and aging deterioration. It is possible to change the threshold value according to the above. Therefore, in the following, the configurations and functions of the detection means 42 and the conversion means 53 connected to the relay devices 46 to 48 by IO-Link will be specifically described.

The first relay device 46 includes a plurality of device communication ports 46d and 46e, and a depth sensor 54 for measuring the depth by raising and lowering the auger 28 is connected to the device communication port 46d via the depth sensor communication line 50a. .. The depth sensor 54 detects the rotation angle of the driven sprocket 34 with an encoder. The detected signal is transmitted to the control device 43 via the first relay device 46 and the switching hub 49, and the depth and the ascending / descending speed are calculated based on the rotation angle and the sprocket diameter.

Further, the tilt sensor 55 that measures the tilt angle of the reader 15 in the front-back and left-right directions is connected to the device communication port 46e via the tilt sensor communication line 50b. The tilt sensor 55 is provided with a well-known pendulum type or float type tilt sensor on the side surface of the reader 15. The signal detected by the tilt sensor 55 is transmitted to the control device 43 as the leader tilt angle via the first relay device 46 and the switching hub 49.

The second relay device 47 includes a plurality of device communication ports 47c, 47d, 47e, and the rotation sensor 56 for measuring the rotation speed of the construction member is connected to the device communication port 47c via the rotation sensor communication line 50c. There is. The rotation sensor 56 detects the teeth of the gear of the output mechanism 39 with a proximity sensor and counts the pulse signal thereof. The signal detected by the rotation sensor 56 is transmitted to the control device 43 via the second relay device 47, the first relay device 46, and the switching hub 49, and the integrated rotation speed and rotation speed are calculated based on the cumulative count. ..

Further, a torque sensor 57 for measuring the torque of the construction member is connected to the device communication port 47d via the torque sensor communication line 50d. The torque sensor 57 is provided with pressure sensors on the supply side of the hydraulic circuit of the auger drive hydraulic motor and the secondary side of the hydraulic circuit of the electromagnetic proportional valve 58, respectively, and the operating pressure and control of the auger drive hydraulic motor are controlled by each pressure sensor. It detects pressure. The signal detected by the torque sensor 57 is transmitted to the control device 43 via the second relay device 47, the first relay device 46 and the switching hub 49, and the construction torque is generated based on the pressure and the capacity of the hydraulic motor for driving the auger. It is calculated. Further, a converter 59 that controls the drive current of the electromagnetic proportional valve 58 is connected to the device communication port 47e via the converter communication line 50e. As a result, the control pressure of the hydraulic motor for driving the auger is adjusted.

The third relay device 48 includes a plurality of device communication ports 48c, 48d, 48e, 48f, and the elevating force sensor 60 for measuring the force required for press-fitting and pulling out the construction member by elevating and lowering the auger 28 communicates with the elevating force sensor. It is connected to the device communication port 48c via the line 50f. The lifting force sensor 60 is provided with pressure sensors on the ascending side and the descending side of the hydraulic circuit of the auger elevating hydraulic motor, respectively, and detects the operating pressure of the auger elevating hydraulic motor by each pressure sensor. The signal detected by the lifting force sensor 60 is transmitted to the control device 43 via the third relay device 48 and the switching hub 49, and the lifting force (press-fitting / pulling out) is calculated based on the pressure.

Further, the flow rate sensor 61 for measuring the injection amount of cement milk is connected to the device communication port 48d via the flow rate sensor communication line 50g. The flow rate sensor 61 measures the flow rate of cement milk supplied from a batcher plant (not shown). The signal detected by the flow rate sensor 61 is transmitted to the control device 43 as an instantaneous flow rate (instantaneous flow rate) and a passing flow rate (integrated flow rate) via the third relay device 48 and the switching hub 49. Further, a converter 63 that controls the drive current of the electromagnetic proportional valve 62 is connected to the device communication port 48e via the converter communication line 50h. As a result, the amount of hydraulic oil supplied to the hydraulic motor for raising and lowering the auger is adjusted.

Further, an analog hub 64 for converting an analog signal into a digital signal is provided in the driver's cab 19, and the other end of the analog hub communication line 50i having one end connected to the output port 64a of the analog hub 64 is provided. It is connected to the device communication port 48f of the third relay device 48. The analog hub 64 includes a plurality of input ports 64b and 64c, and a changeover switch 65 for switching the ascending / descending speed and torque magnitude of the auger 28 is connected to the input port 64b via the switch communication line 50j to provide a dial. The adjustment dial 66, which adjusts according to the rotation state, is connected to the input port 64c via the dial communication line 50k. Then, the signals of the changeover switch 65 and the adjustment dial 66 transmitted to the third relay device 48 by the operation of the operator are transmitted to the control device 43 via the switching hub 49, and the hydraulic motor for raising and lowering the auger based on the set state. And hydraulic motors for auger drive are driven.

In the pile driver 11 provided with the construction management device 41 formed in this way, the auger 28 is removed from the reader 15 and the leader 15 is divided in order to obtain a mass and length dimension suitable for transportation, for example. The upper reader 24 may be separated from the intermediate reader 23 and transported separately. At this time, the second relay device 47 has the second upper communication line 45c removed from the upper communication ports 46b and 47a, that is, the state in which the network connection between the first relay device 46 and the second relay device 47 is disconnected. Then, it is removed from the reader 15 together with the auger 28, and is loaded and transported together with the auger 28 on the loading platform of the transport truck. Further, the first relay device 46 is intermediate with the first upper communication line 45b removed from the upper communication ports 49c and 46a, that is, with the network connection between the switching hub 49 and the first relay device 46 disconnected. By breaking the connection between the second member 23b and the upper first member 24a, the intermediate leader 23 is integrally removed from the upper leader 24, and is loaded on the loading platform of the transport truck together with the upper leader 24 and transported.

The removed first upper communication line 45b and second upper communication line 45c can be carried in a storage case. For example, in the case of the first upper communication line 45b, the switching hub 49 side is not removed. In a state of being bundled in a ring shape, it can be fixed to the upper swivel body 13 by using a binding band or the like and transported.

After assembling various parts such as the reader 15 and the auger 28 at the site, the first upper communication line 45b is connected to each upper communication port 49c, 46a, and the second upper communication line 45c is connected to each upper communication port 46b, 47a. By connecting, the network that was once disconnected during transportation is restored, and the power supply of the construction management device 41 can be turned on.

In this way, the result of detection by the plurality of detection means 42 is indirectly transmitted to the control device 43 via the relay devices 46 to 48, so that the short distance between the detection means 42 and the relay devices 46 to 48 is short. Although the same number of device communication lines 50 as the detection means 42 are required for the distance wiring, one upper communication line 45 is sufficient for the long-distance wiring between each relay device 46 to 48 and the control device 43. This makes it possible to simplify the communication line between the detection means 42 and the control device 43 and facilitate the wiring work. In particular, since the second relay device 47 moves up and down together with the auger 28 during construction, the upper communication line 45 connected to the second relay device 47 tends to be consumed relatively quickly, but the first relay device 46 and the second relay device It is possible to connect to 47 with a second upper communication line 45c having a length suitable for replacing parts, and maintainability can be improved.

Further, since the first relay device 46 is distributed and arranged on the reader 15 and the second relay device 47 is distributed on the auger 28, and the reader 15 and the auger 28 are integrally and detachably formed, the reader 15 and the auger are formed. When disassembling and assembling the 28, the wiring work of the device communication line 50 is not required, and only the wiring work of the upper communication line 45 can be completed, and the network connection of the construction management device 41 can be efficiently and stably released and restored. It can be carried out.

When the power supply of the construction management device 41 is turned on, each of the relay devices 46 to 48 monitors whether or not it is in a state to be alarmed based on the state of the network connection, the detection means 42, and the like. As described above, since the wiring work of the device communication line 50 is omitted at the time of disassembling and assembling the reader 15 and the auger 28, troubles caused by the wiring work of the device communication line 50 are prevented, while the reader is used. The detection means 42, for example, the depth sensor 54 may fail due to vibration during disassembly and assembly of 15. In such a case, a signal that the depth sensor 54 is in a failed state is output from the device monitoring unit 46c of the first relay device 46, and based on this output result, the control device 43 displays the depth sensor 54 on the display 44. Display a message that is in a failed state.

As a result, the operator can easily identify the location of the failure and the cause of the failure, and the maintainability of the construction management device 41 can be improved. Further, since the status of the construction management device 41 is monitored by the IO-Link communication based on the identification information and the diagnostic information of the detection means 42, the network connection is repeatedly disconnected and restored every time the pile driver 11 moves to the site. However, the ready-made pile method, cast-in-place pile method or ground improvement method can be carried out in a stable state.

The boom 72, which is provided so as to be undulating and is formed by connecting the upper boom 72a, the intermediate boom 72b, and the lower boom 72c, which are boom members, to each other, and the main that hangs down from the point sheave 72d attached to the tip of the upper boom 72a. A kelly bar 75 rotatably suspended from a winding rope 73 via a swivel 74, a kelly drive 78 supported by a front frame 76 having a base end attached to a lower boom 72c, a holding cylinder 77, and the like, and a kelly bar 75. It is provided with a bottom expansion bucket 79 attached to the lower end portion of the.

A plurality of hydraulic pipes 80 for operating the kelly drive 78, the bottom expansion bucket 79, and the like are provided along the front frame 76 above the front portion of the upper swivel body 13. A gantry 81 is erected at the rear of the upper swing body 13, and the undulating rope 83 from the undulating winch 82 is connected to a bracket 72e provided at the tip of the upper boom 72a via a pendant rope 84. .. Further, a driver's cab 19 and an equipment room 20 are provided on the right side of the upper swing body 13, and an engine room (not shown) containing an engine and a hydraulic pump is provided on the left side.

To form a pile hole with the earth drill 71, the undulating winch 82 is used to operate the undulating rope 83 to raise the boom 72 at a predetermined angle, and the kelly drive 78 is placed at a predetermined position to form the kelly bar 75 with the kelly drive 78. It is performed by alternately repeating the process of pushing the excavation bucket or the bottom expansion bucket 79 into the ground while rotating the excavation bucket or the bottom expansion bucket 79 by rotating the excavation bucket or the bottom expansion bucket 79 and discharging the excavated earth and sand by pulling up the excavation bucket or the bottom expansion bucket 79.

Next, the construction management device of the present invention applied to the earth drill 71 will be described with reference to FIGS. 2 and 3. As shown in the block diagram of FIG. 2, this construction management device is configured in common with the construction management device 41 of the pile driving machine 11, and the control device 43 executes a construction management program for constructing the earth drill method. To. Further, in order to correspond to the form of the earth drill 71, the mounting positions of the detecting means 42 and the relay devices 46 to 48 are different from the mounting positions of the pile driver 11, but the operating principle by the control device 43 is the same. Is.

For each of the relay devices 46 to 48, the first relay device 46 (boom side relay device of the present invention) is on the side surface of the lower boom 72c, specifically, on the base end portion of the front frame 76, and the second relay device 47 (this). The Kelly drive side relay device of the present invention) is screwed to the side surface of the Kelly drive 78, and the third relay device 48 is screwed into the equipment chamber 20 of the upper swing body 13 via a mounting seat.

As an example of the detection means 42, in the second relay device 47, a rotation sensor 56 for measuring the rotation speed of the kelly bar 75 is connected to the device communication port 47c via the rotation sensor communication line 50c. The rotation sensor 56 detects the teeth of the gear of the output mechanism 85 with a proximity sensor and counts the pulse signal thereof. The signal detected by the rotation sensor 56 is transmitted to the control device 43 via the second relay device 47, the first relay device 46, and the switching hub 49, and the integrated rotation speed and rotation speed are calculated based on the cumulative count. ..

The earth drill 71 provided with the construction management device 41 thus formed assembles the kelly drive 78, the kelly bar 75, and the bottom expansion bucket 79 at the front of the base machine 14 in order to have a mass and length dimensions suitable for transportation. The boom 72 may be divided into a plurality of parts and transported separately while being disassembled from the state of being disassembled. At this time, the second relay device 47 has the second upper communication line 45c removed from the upper communication ports 46b and 47a, that is, the state in which the network connection between the first relay device 46 and the second relay device 47 is disconnected. Then, it is integrally removed from the front frame 76 and the holding cylinder 77 together with the kelly drive 78, and is loaded and transported together with the kelly drive 78 on the loading platform of the transport truck. Further, the first relay device 46 has an upper portion in a state where the first upper communication line 45b is removed from the upper communication ports 49c and 46a, that is, in a state where the network connection between the switching hub 49 and the first relay device 46 is disconnected. By disconnecting the boom 72a, the intermediate boom 72b, and the lower boom 72c from each other and disconnecting the upper swing body 13 and the lower boom 72c, the upper swing body 13 is integrally removed from the lower boom 72c, and the lower boom is removed. Together with 72c, it is loaded on the loading platform of a transportation truck and transported.

After assembling various parts such as the boom 72 and the kelly drive 78 at the site, the first upper communication line 45b is connected to each upper communication port 49c, 46a, and the second upper communication line 45c is connected to each upper communication port 46b, 47a. By connecting to, the network that was once disconnected during transportation is restored, and the power supply of the construction management device 41 can be turned on.

In this way, the result of detection by the plurality of detection means 42 is indirectly transmitted to the control device 43 via the relay devices 46 to 48, so that the short distance between the detection means 42 and the relay devices 46 to 48 is short. Although the same number of device communication lines 50 as the detection means 42 are required for the distance wiring, one upper communication line 45 is sufficient for the long-distance wiring between each relay device 46 to 48 and the control device 43. This makes it possible to simplify the communication line between the detection means 42 and the control device 43 and facilitate the wiring work.

Further, since the first relay device 46 is distributed and arranged on the boom 72 and the second relay device 47 is distributed on the kelly drive 78, and the boom 72 and the kelly drive 78 are integrally detachably formed, the boom 72 is formed. When disassembling and assembling the Kelly Drive 78, the wiring work of the device communication line 50 is not required, and only the wiring work of the upper communication line 45 can be completed, and the network connection of the construction management device 41 can be efficiently disconnected and restored. It can be done stably.

When the power supply of the construction management device 41 is turned on, each of the relay devices 46 to 48 monitors whether or not it is in a state to be alarmed based on the state of the network connection, the detection means 42, and the like. As described above, since the wiring work of the device communication line 50 is omitted at the time of disassembling and assembling the boom 72 and the kelly drive 78, troubles caused by the wiring work of the device communication line 50 are prevented. The detection means 42, for example, the rotation sensor 56 may fail due to vibration during disassembly and assembly of the kelly drive 78. In such a case, a signal that the rotation sensor 56 is in a failed state is output from the device monitoring unit 47b of the second relay device 47, and based on this output result, the control device 43 displays the rotation sensor 56 on the display 44. Display a message that is in a failed state.

As a result, the operator can easily identify the location of the failure and the cause of the failure, and the maintainability of the construction management device 41 can be improved. Further, since the status of the construction management device 41 is monitored by IO-Link communication based on the identification information and the diagnostic information of the detection means 42, the network connection is repeatedly disconnected and restored every time the earth drill 71 is moved to the site. However, the earth drill method can be constructed in a stable state.

The present invention is not limited to the ready-made pile construction method, the cast-in-place pile construction method, the ground improvement construction method, or the earth drill construction method, but can be constructed by various pile construction methods and various ground improvement construction methods. Further, the number and mounting positions of the relay devices are arbitrary as long as the network connection can be safely performed without hindering the attachment and detachment of various components in the pile driver and the earth drill. Further, various detection means can be applied according to the purpose of construction management. For example, when an electric motor is applied to a drive source of an auger drive motor or a kelly drive drive motor, a current sensor is used. , The construction torque is calculated based on the current detected by this current sensor. Further, PROFINE is adopted as the industrial Ethernet for the network, but the present invention is not limited to this, and for example, EtherCAT (registered trademark) or the like can be adopted. Further, a network can be configured in combination with CAN communication or the like.
