Description

  The present invention relates to a vibrator device for compacting concrete, a vibrator position measuring system, and a method for measuring the position of a vibrator for compacting concrete.

  In concrete construction related to walls, slabs, etc., flexible vibrators are widely used in which the power source and vibrator body are connected by a hose containing a flexible shaft when compacting the placed concrete. .

  Patent Document 1 discloses a flexible vibrator in which a vibrating body is connected to a power source having a commutator motor and a gear box via a driving flexible shaft housed in a hose.

JP 2011-236667 A

In the conventional flexible vibrator as described above, it is difficult to grasp the exact position of the vibrator main body inserted into the concrete. For example, it is difficult to manage which height and how much is compacted in the construction of a wall or the like.
Regarding the grasping of the position of the vibrator body, for example, a method of marking the outside of the hose at regular intervals with a vinyl tape or the like, and referring to the mark attached to the portion exposed from the concrete of the hose during construction, Has been done. It is also possible to attach a scale to the hose. However, since the marks and scales are soiled by concrete during construction, it is difficult to repeatedly use them. In particular, the marks may be peeled off and thus lack reliability. In addition, both methods require extra labor for position measurement, and are not realistic.

  It is also conceivable to incorporate a transmitter capable of transmitting any signal into the vibrator body, and to recognize the position by wirelessly transmitting and receiving signals between the transmitter and a receiver held by an operator. However, during compaction work, since concrete, metal, or the like is interposed between the transmitter and the receiver, the reliability of signal transmission / reception may be reduced due to the influence of these substances.

  As for the degree of compaction, it is possible to measure the time required for compaction during construction, but it requires labor.

  Therefore, the adjustment of the insertion position of the vibrator main body and the judgment of whether or not sufficient tightening has been performed at that position depend on the intuition and experience of the workers at present, so that the compaction is insufficient. There is a possibility that problems such as poor construction caused by the

In addition, particularly in the case of placing concrete in a vast place such as a dam construction, it is important to manage not only the depth position of the vibrator body but also the horizontal position after compaction.
At present, we report and manage which places have been compacted by visual confirmation and verbal communication between workers or field supervisors, but due to human error in reporting and management, There may be places that have not been hardened or have not been fully done.

  Furthermore, in any of the above cases, it is difficult and time-consuming to record the position and degree of compaction as a record. Even if a record is left, it is difficult to easily perform the work when referring to the record at a later date or taking some statistics on various sites.

  An object of the present invention is to accurately measure the position of a vibrator body.

The present invention employs the following means in order to solve the above problems.
That is, the present invention is a vibrator device for compacting concrete comprising a main body having a vibrating body and a power transmission hose having one end connected to the main body and transmitting power to the main body. And a receiver for receiving the signal from the plurality of transmitters, wherein the plurality of transmitters are disposed on the power transmission hose in the length direction of the power transmission hose. Provided is a vibrator for compaction of concrete provided at intervals.
According to such a configuration, the receiver receives and identifies the signal transmitted by each of the transmitters, which is provided on the power transmission hose at intervals in the length direction of the power transmission hose. Therefore, the distance between the main body and the transmitter, that is, the relative position of the main body from the receiver can be accurately grasped based on the received signal.
Further, since the receiver can recognize the position of the main body by receiving the signal transmitted by the transmitter, it can be used repeatedly without being affected by dirt. In addition, the operator can unconsciously measure the position, and the working efficiency of compaction does not deteriorate.
Furthermore, since the transmitter is provided on the power transmission hose, the operator can measure the position of the main body by bringing the receiver closer to the power transmission hose. That is, since a large amount of concrete or metal is not interposed between the transmitter and the receiver, an accurate and reliable operation can be expected.

The plurality of transmitters may be arranged in a spiral pattern in the length direction of the power transmission hose and spaced apart on the pattern.
According to such a configuration, the transmitter can be efficiently arranged, and the apparatus can be manufactured at low cost.

The plurality of transmitters may be arranged with a plurality of spiral patterns arranged at different positions in the length direction of the power transmission hose and spaced apart on the pattern.
According to such a configuration, it is possible to reduce the number of parts of the power transmission hose where the transmitter is not arranged, while allowing efficient arrangement of the transmitter, so that the inexpensive manufacture and position of the device can be achieved. It is possible to improve the reliability of measurement.

The receiver may be provided in an operator's gloves.
According to such a configuration, the operator can measure the position unconsciously only by using the equipment normally used, and the work efficiency is not deteriorated.

The apparatus further includes a GPS receiver and a power source to which the other end of the power transmission hose is connected. The power source includes a current monitor and a transmission circuit, and the current monitor is driven by the power source. The transmission circuit may transmit the time.
According to such a configuration, since the worker's work position can be specified, the horizontal position of the place where the compaction is performed can be easily managed even in a large site.
In addition, since the time required for compaction can be accurately measured and viewed, it is possible to prevent the shortage of compaction due to operator error.

The present invention also includes a main body having a vibrating body, a power transmission hose having one end connected to the main body and transmitting power to the main body, a plurality of transmitting bodies that transmit signals, and the plurality of transmitting bodies. A receiver for receiving the signal from a body, wherein the plurality of transmitters are provided on the power transmission hose at intervals in the length direction of the power transmission hose. A method for measuring a position of a vibrator for compacting concrete, wherein the position of the main body is measured using an apparatus, wherein the receiver sends the signal from the transmitter closest to the receiver among the plurality of transmitters. A position measuring method for a concrete compaction vibrator, comprising:
According to such a configuration, the receiver receives and identifies the signal transmitted by each of the transmitters, which is provided on the power transmission hose at intervals in the length direction of the power transmission hose. Therefore, the distance between the main body and the transmitter, that is, the relative position of the main body from the receiver can be accurately grasped based on the received signal.
Further, since the receiver can recognize the position of the main body by receiving the signal transmitted by the transmitter, it can be used repeatedly without being affected by dirt. In addition, the operator can unconsciously measure the position, and the working efficiency of compaction does not deteriorate.
Furthermore, since the transmitter is provided on the power transmission hose, the operator can measure the position of the main body by bringing the receiver closer to the power transmission hose. That is, since a large amount of concrete or metal is not interposed between the transmitter and the receiver, an accurate and reliable operation can be expected.

It is a conceptual diagram of a vibrator position measuring system using the vibrator device shown as the embodiment.

  Hereinafter, the present invention will be described in detail with reference to the drawings.

FIG. 1 shows a vibrator 1 for compacting concrete shown as an embodiment of the present invention. The vibrator device 1 includes a main body 2, a power transmission hose 3, a power source (not shown), a plurality of transmitters 4, and a receiver 5.
The main body 2 has a vibrating body, that is, a vibrator.
The power transmission hose 3 has one end connected to the main body 2 and the other end connected to a power source. The power transmission hose 3 transmits power generated by the power source to the main body 2.

  FIG. 2 is a cross-sectional view of the power transmission hose 3. The power transmission hose 3 includes a protective outer skin 10 such as rubber and a flexible shaft 11. Since both the protective outer skin 10 and the flexible shaft 11 are made of a flexible material or structure, the power transmission hose 3 is easy to bend, so that an operator can easily insert and install the main body 2 at any place. Is possible.

The power transmission hose 3 has a plurality of transmitters 4 so as to be sandwiched between the protective outer skin 10 and the flexible shaft 11. Any transmitter may be used as long as it transmits a certain signal. Hereinafter, in order to simplify the description, it is assumed that the transmitter 4 is a passive RFID tag 4. FIG. 2 shows an example in which a plurality of RFID tags 4 are arranged in different radial directions at the same relative position from the main body 2 of the power transmission hose 3.
Each of the plurality of RFID tags 4 transmits different information, for example, ID information. As shown in FIG. 1, the RFID tag 4 is provided on the power transmission hose 3 at intervals in the length direction of the power transmission hose 3.

  The RFID tag 4 may set a spiral pattern in the length direction of the power transmission hose 3, and may be arranged on the pattern at intervals. The angle of the spiral pattern with respect to the longitudinal axis of the power transmission hose 3 is preferably 30 ° to 60 °, particularly 45 °. As will be described later, ID information transmitted by the RFID tag 4 is received using a receiver 5 provided on a glove worn on the worker's hand. This is because the angle formed by the hand and the power transmission hose 3 when pushing and pulling the transmission hose 3 is an angle close to 45 °. This angle is not limited to 30 ° to 60 °.

  The RFID tag 4 may set a plurality of spiral patterns arranged in a shifted position in the length direction of the power transmission hose 3 and be arranged at intervals on the pattern. An arrangement example in this case is shown in FIG. In FIG. 3, the RFID tags 4 are arranged in two spiral patterns.

  The receiver 5 shown in FIG. 1 includes an antenna 6, an electronic circuit 7, and a display panel 8. The antenna 6 receives ID information transmitted from the RFID tag 4. The receiver 5 in this embodiment is provided in a glove, and therefore the antenna 6 has a structure that can be bent.

  FIG. 4 shows how a signal is received from the RFID tag 4 by the receiver 5. An operator holds the power transmission hose 3 in a state where a glove provided with the receiver 5 is worn on the hand. At this time, the ID information of the RFID tag 4 closest to the antenna 6 of the receiver 5 is received by the antenna 6.

  FIG. 5 shows a modification in which the receiver 5 includes three antennas 6. According to such an arrangement of the antenna, for example, even when only one RFID tag 4 is arranged at the same relative position from the main body 2 of the power transmission hose 3, the rotation of the power transmission hose 3 is rotated. It becomes possible to have stable reception accuracy regardless of the position.

  The electronic circuit 7 of the receiver 5 performs various signal processing based on the received ID information. For example, the correspondence between the ID information of each RFID tag 4 and the relative position of the RFID tag 4 from the main body 2 can be realized so as to be held inside. Further, information that can recognize the relative position of the receiver 5 from the concrete surface, such as the height of the worker or the position of the hand during work, is recorded in advance, and the main body of the RFID tag 4 having the received ID information The position of the main body 2 in the concrete may be calculated from the relative position from 2 and the relative position of the receiver 5 from the concrete surface.

  The display panel 8 of the receiver shown in FIG. 1 displays information related to the position of the main body 2 calculated by the electronic circuit 7.

  Next, based on this embodiment, the procedure for measuring the position of the main body 2 using the vibrator device 1 will be described.

First, an operator inserts the power transmission hose 3 into the placed concrete and pushes and pulls the power transmission hose 3 to install the main body 2 in a place where compaction is desired.
After the main body 2 is installed, the place is compacted for an appropriate time.

  During the compacting operation, the operator holds a certain portion of the power transmission hose 3. When the antenna 6 of the receiver 5 provided on the glove worn by the operator continues to receive ID information transmitted by the same RFID tag 4 for a certain period of time, the electronic circuit 7 of the receiver 5 However, it is determined that the compacting operation is being performed at the position corresponding to the RFID tag 4.

The electronic circuit 7 of the receiver 5 calculates the relative position from the main body 2 of the RFID tag 4 having the ID information based on the received ID information.
The electronic circuit 7 further calculates the position of the main body 2 in the concrete from the calculated relative position and the relative position information of the receiver 5 from the concrete surface.

  The display panel 8 of the receiver 5 displays information related to the position of the main body 2 calculated by the electronic circuit 7.

According to the vibrator device 1 configured as described above, the ID information transmitted by each of the RFID tags 4 provided on the power transmission hose 3 at intervals in the length direction of the power transmission hose 3 is received. Since the machine 5 can receive and identify, the distance between the main body 2 and the RFID tag 4, that is, the relative position such as the depth from the receiver 5 of the main body 2 can be accurately determined based on the received ID information. I can grasp it.
In addition, since the receiver 5 receives the ID information transmitted by the RFID tag 4, the position of the main body 2 can be grasped, so that it can be used repeatedly without being affected by dirt. Further, the operator can unconsciously measure the position, and work efficiency is not deteriorated.
Furthermore, since the RFID tag 4 is provided on the power transmission hose 3, the operator can measure the position of the main body by bringing the receiver 5 close to the hose. That is, since a large amount of concrete or metal is not interposed between the RFID tag 4 and the receiver 5, an accurate and highly reliable operation can be expected.

  In addition, since the RFID tag 4 is arranged in a pattern as shown in FIG. 3, the transmitter can be efficiently arranged, but there are few parts of the power transmission hose where the transmitter is not arranged. Therefore, it is possible to achieve both low-cost manufacturing of the device and improved reliability of position measurement.

  Further, since the receiver 5 is provided on the operator's gloves, the operator can measure the position unconsciously only by using the equipment normally used, and the work efficiency is not deteriorated.

  Further, since the passive RFID tag 4 is used as the transmitter, power supply and charging to the transmitter are not required, and no particular maintenance is required to continue using the apparatus. Further, since the RFID tag 4 and the reader, that is, the antenna 6 are mass-produced and are inexpensive, the apparatus can be manufactured at low cost.

  Since each RFID tag 4 transmits different ID information, it is possible to prevent the receiver 5 from erroneously calculating the position of the main body 2 by identifying the wrong RFID tag 4.

In the present embodiment, the RFID tag 4 is a passive type, but is not limited thereto.
When the RFID tag 4 is of an electromagnetic induction type of 13.56 MHz or 135 kHz or less, it is possible to reduce the influence of mortar, metal, etc. attached to the periphery of the power transmission hose 3 that obstructs reading of the RFID tag 4 Therefore, it is preferable, but not limited to this.
In this case, the interval between the RFID tags 4 is preferably 10 to 20 cm. However, the present invention is not limited to this, and as long as a plurality of RFID tags 4 do not enter the detection range of the antenna 6, the RFID tag standard and the body to be measured You may select appropriately based on the measurement particle size of 2 position, cost, etc.

  For embedding the RFID tag 4 in the power transmission hose 3, for example, a tape-like one in which the RFID tags 4 are arranged in advance at a predetermined interval is created, and this is attached before or once attached to the protective skin 10. By sticking to the flexible shaft 11 from which the protective skin 10 has been peeled off, it can be easily implemented.

  In the present embodiment, the receiver 5 is provided in a glove worn by an operator. However, the present invention is not limited to this. For example, a bar-shaped or ring-shaped receiver 5 is prepared separately from the glove worn during work. This may be used.
