Description

  The present invention detects deformation, movement, breakage, etc. of a main anchor that fixes a winch wire of a work vehicle that operates on a steeply inclined surface, etc., and the main anchor is deformed, moved, broken, etc. under the load of the work vehicle. In this case, the present invention relates to a method and an apparatus for detecting movement of a main anchor that warns a worker of a work vehicle.

  When working with a work vehicle (heavy equipment) on a slope (mainly steep slope), fix the winch wire provided on the work vehicle to the main anchor (standing tree, rock bolt, larger heavy equipment, etc.) at the top of the slope. Then, the work vehicle is moved to a predetermined position by expanding and contracting the wire with the winch, and operations such as drilling are performed. This wire is used not only for the movement of the work vehicle but also as a lifeline to prevent the fall when the slope breaks, and whether the main anchor is sturdy or not works safely Is very important above.

  Conventionally, when working on a slope, the main anchor is subjected to a test by applying a load multiplied by a safety factor to the load applied at the start of the work, and after confirming the safety, the wire of the work vehicle is However, there was no means to detect even if the main anchor moved under load or deformed during the work, and the work was done in a dangerous state.

nothing special

  In view of the above-described conventional drawbacks, the present invention provides a main anchor movement detection method and apparatus capable of safely performing work by sensing the movement and deformation of the main anchor during work and notifying the worker. It is an object.

To achieve the above object, the present invention provides a wire fixing step for fixing a wire of a winch of a work vehicle that operates on a slope to a main anchor, and a movement detection sensor for the main anchor to which the wire is fixed in the wire fixing step. And a movement detection sensor arranged in the movement detection sensor arrangement step detects the movement of the main anchor, and the movement detection sensor The main anchor includes a warning transmission step of transmitting a warning signal from the connected transmitter, and a notification step of receiving the warning signal transmitted in the warning transmission step and notifying the worker in real time that the main anchor has moved. The movement detection method is configured.

The present invention also provides a main anchor for fixing a winch wire of a work vehicle that performs work on a slope, a movement detection sensor that detects the movement of the main anchor when the work anchor is moved by the load of the work vehicle, and the movement A transmitter that is connected to a detection sensor and that transmits a warning signal to a worker of the work vehicle when the movement detection sensor detects the movement of the main anchor; and a work that receives the warning signal transmitted from the transmitter The main anchor movement detection device is constituted by the notification means for notifying a member in real time .

As is clear from the above description, the present invention has the following effects.
(1) In the invention of claim 1, even if the main anchor loses the weight of the work vehicle and moves / deforms, the movement is detected by the movement detection sensor and notified to the worker in real time. it can.
Therefore, the work can be performed safely.
(2) Since the movement detection sensor is arranged with respect to the main anchor and only a device capable of transmitting and receiving the sensor signal is used, it can be easily used at various sites.
(3) The invention of claim 2 can also achieve the same effects as the above (1) to (2).

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

  In the first embodiment for carrying out the present invention shown in FIGS. 1 to 4, reference numeral 1 denotes a main anchor movement detection method performed by using a main anchor movement detection device 2, and this main anchor movement detection method 1. Is a wire fixing step 7 for fixing the wire 5 of the winch 4 of the work vehicle 3 (a heavy machine such as a drilling device or a shovel car) working on the slope, and the wire 5 is fixed in the wire fixing step 7 The movement detection sensor placement step 9 for placing the movement detection sensor 8 on the main anchor 6 that has been moved, and the movement detection sensor placement step when the main anchor 6 has moved (including deformation, breakage, etc.) due to the load of the work vehicle. The movement detection sensor 8 arranged at 9 detects the movement of the main anchor 6, and transmits a warning signal 11 from the transmitter 10 connected to the movement detection sensor 8, and the warning transmission process 1 In receiving the transmitted warning signal, a main anchor 6 it can be more configuration and notification process 13 for informing the operator by the notification unit 12 that it has moved.

The main anchor movement detection device 2 includes a main anchor 6 that fixes the wire 5 of the winch 4 of the work vehicle 3 that operates on a slope, and a movement that detects the movement when the main anchor 6 moves. A detection sensor 8 and a transmitter 10 connected to the movement detection sensor 8 for transmitting a warning signal to an operator of the work vehicle 4 when the movement detection sensor 8 detects the movement of the main anchor 6; It is comprised from the alerting | reporting means 12 which receives the warning signal transmitted from the transmitter, and alert | reports to a worker.

The wire fixing step 7 is a step of pulling out the wire 5 of the winch 4 of the work vehicle 3 that performs work on a slope such as a drilling device, a breaker, or a shovel car, and fixing the wire 5 to the main anchor 6. As the main anchor 6, a standing tree, a lock bolt, a heavy machine larger than a work vehicle, etc. above the slope are used. In the wire fixing step 7, a tensile test of the main anchor 6 is also performed as in the prior art.

In the movement detection sensor arrangement step 9, the movement detection sensor 8 is arranged on the main anchor 6, and when the main anchor 6 is moved or deformed, the abnormality is detected and a warning signal is transmitted to the transmitter 10. It is a process of setting. In the present embodiment, the wire sensor 14 is used as the movement detection sensor 8, the wire sensor 14 is fixed to the main anchor 6, and the transmitter 10 that transmits a warning signal is connected to the wire sensor 14.
In the warning transmission step 11, when the main anchor 6 moves, deforms or the like as shown in FIG. 3, the movement detection sensor 8 detects the movement and outputs a warning signal. When the warning signal is output, the transmitter 10 connected to the movement detection sensor 8 transmits the warning signal wirelessly. When the wire sensor 14 is used as in the present embodiment, when the main anchor 6 moves, the wire of the wire sensor 14 is moved or broken, and the wire sensor 14 detects this and outputs a warning signal. The transmitter 10 transmits the signal.

  In the notification step 13, as shown in FIG. 4, a warning signal transmitted from the transmitter is received by the notification means 12, and a danger is notified to the worker by a warning sound, a buzzer, a visual effect, or the like. A specific example of the notification means 12 includes a receiver 15 that receives a warning signal, and a speaker 16 and a rotating lamp 17 that notify the worker of the danger when the receiver 15 receives the warning signal. Can be considered. Such a notification means 12 is installed in the work vehicle when the worker gets on the work vehicle 3 and works when the worker operates the unmanned work vehicle 3 wirelessly from an office or the like. Is installed in the office.

In addition, the alerting | reporting means 12 should just receive the said signal and can alert | report danger to an operator, and is not limited to the said structure. For example, the warning signal may be received by a terminal such as a smartphone, a tablet, or a personal computer and notified by a display and a speaker, or a wearable terminal is attached to a worker, the warning signal is received by the wearable terminal, voice, You may alert | report by an image etc.
