DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an earth and sand conveying device.

[0002]

2. Description of the Related Art Conventionally, as a general method for forming a borehole, a work stage is assembled at an upper opening of the borehole, and a cylindrical center casing is placed on the workstage toward a lower part inside the borehole. Attach, insert the bucket suspended by the large crane from the center casing into the inside of the drill hole, load the earth and sand excavated inside the drill hole into the bucket, and then lift the bucket with the crane to the outside of the drill hole. He was trying to discharge earth and sand.

[0003]

However, in the above-mentioned conventional construction method, a large-scale operation such as assembling a work stage at the upper opening of the excavation hole is required, which requires a great deal of labor and time. Since the opening of the hole is covered by the work stage, there is a problem that the inside of the excavation hole becomes dark and the workability is reduced.

In addition, when the earth and sand are discharged, the vibration of the crane is transmitted to the bucket, and there is a risk that the earth and sand may fall from the bucket into the inside of the excavation hole.

Further, in order to discharge the conveyed earth and sand from the bucket, a complicated operation such as reversal of the bucket is required by an operator, which requires a great deal of labor and time.

Further, the crane used in the conventional construction method has only a function of transporting earth and sand, and in order to transport a working machine or an operator, it is necessary to separately prepare a dedicated device. And was uneconomical.

[0007]

Therefore, according to the present invention, a bucket for loading earth and sand is pivotally connected to a transportable vehicle that can travel along rails.

Further, a bucket for loading earth and sand is rotatably pivoted on a transport vehicle that can travel along the rails, and a bucket for reversing the bucket is provided in a middle portion of the transport path of the transport vehicle. A bucket reversing mechanism is provided.

Further, the lid is rotatably covered at the opening of the bucket, and the bucket reversing mechanism is provided with a lid opening means for rotating the lid to open the lid. .

[0010] Further, the carrier is constituted by a driving vehicle formed so as to be able to run along the rails and a driven vehicle connected to the driving vehicle.

Further, a step is attached to the carrier so that a person can get on the vehicle using the step.

Further, a rail is provided in the excavation hole, and a bucket for loading earth and sand is rotatably pivoted on a carrier that can travel along the rail. The excavated earth and sand was loaded, and then the carrier was driven to discharge the earth and sand outside the excavation hole.

[0013]

76 is stowed (standing)
Is a safety belt, which is a safety belt, which can be housed inside the driving vehicle body 21 when not in use.

The earth and sand transport device 1 is configured as described above, and is used as described below.

First, a case where the earth and sand is conveyed using the earth and sand conveying device 1 will be described.

(1) When the soil and sand transport device 1 is not used, the transport vehicle 5 is stopped at a position approximately 2 m above the bottom of the excavation hole 3.

(2) Next, the worker keeps pressing the down button of the remote controller, thereby lowering the carrier 5, and the operator stops pressing the down button of the remote controller, thereby moving the carrier 5. Stop.

(3) Next, the excavated earth and sand is loaded inside the bucket body 37.

(4) Next, the worker presses the up button of the remote controller to raise the carrier 5.

(5) As described above, the transport vehicle 5
The bucket 6 is automatically inverted when the has passed the support frame 58 to discharge the earth and sand.

At this time, the bucket 6 is automatically stopped by detecting that the bucket 6 has been inverted by the bucket inversion detection sensor 36.

(6) Thereafter, after a lapse of a predetermined time (for example,
After 3 seconds), the transport vehicle 5 is automatically moved in the opposite direction to return the bucket 6 to the normal state.

At this time, if the bucket reversal detection sensor 36 detects that the bucket 6 has not been returned to the normal state and is still reversed, the transport vehicle 5 is stopped and a warning sound is generated. I have to. On the other hand, when the bucket 6 has returned to the normal state, the transport vehicle 5 is lowered again, and about 2
Stop at m.

Next, a case in which a person is transported using the earth and sand transport device 1 will be described.

(1) Similarly to the above, when the soil and sand transport device 1 is not used, the transport vehicle 5 is stopped at a position approximately 2 m above the bottom of the excavation hole 3.

(2) Next, the operator keeps pressing the down button of the remote controller to lower the carrier 5 and the operator stops pressing the down button of the remote controller, thereby moving the carrier 5 down. Stop.

(3) Next, the worker changes the step 65 from the standing state to the lying state, and gets on the upper part of the step 65.

At this time, when the step storage detecting sensor 68 detects that the step 65 is in the lying state, the remote controller does not allow the carrier 5 to be remotely operated, and the driving vehicle 18
The operation of the transport vehicle 5 cannot be performed by the operation switch 69 provided on the vehicle.

Therefore, after the operator falls down on the step 65 and gets on the upper part of the step 65, even if the operator operates the external remote controller erroneously, or the operator's body contacts the operation switch 69 erroneously. Even so, the transport vehicle 5 does not move up or down against the intention of the worker, and safety can be improved.

(4) Next, the worker changes the protection bar 76 from the standing state to the lying state.

At this time, when the protection bar storage detecting sensor 70 detects that the protection bar 76 is in the down state, the carrier 5 can be operated only by the operation switch 69 provided on the drive vehicle 18. I have to.

Therefore, only when the protection bar 76 is lying down to protect the body of the working vehicle, the transport vehicle 5 moves up or down, whereby the safety can be improved.

(5) Next, the worker keeps pressing the up button of the operation switch 69 to raise the carrier 5, and the operator stops pressing the up button of the operation switch 69 to stop the carrier. Stop 5

(6) Then, the worker changes the protection bar 76 from the laid state to the upright state, descends from step 65, and changes the step 65 from the laid down state to the upright state.

This allows the remote controller to be operated again. By pressing the down button of the remote controller, the transport vehicle 5 is lowered again and stopped at a position approximately 2 m above the bottom of the excavation hole 3.
