Description

[Detailed Description of the Invention] The present invention relates to a jet water excavator used for drilling holes in tunnels and other excavation work, partially cutting rocks in construction work, etc., and cutting concrete for walls, columns, etc. in building demolition.

Conventional excavators are mainly shovel-type excavators that perform excavation work by attaching various front attachments for excavation, such as buckets, to the main body. This is particularly problematic when working in closed areas such as tunnels, and also in urban areas.

On the other hand, a method called waterjet excavation, which excavates using high-pressure water jetted from a nozzle, has been developed, making it possible to excavate rock without noise or vibration. Or they are fixed in one place,
It was inefficient in terms of workability.

An object of the present invention is to provide a waterjet excavator that utilizes the advantages of waterjet excavation, expands its working range, and improves operability.

However, according to the present invention, the purpose of the lever is to erect a height-adjustable column on a vehicle or a trolley so that it can move left and right, and to hold the jet water nozzle with an arm that protrudes from the tip of the column so that it can move back and forth. This is achieved by

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

Figure 1 is a side view showing an embodiment of the jet water excavator of the present invention, Figure 2 is a plan view of the same, and Figure 3 is a side view showing an embodiment of the jet water excavator of the present invention.
The figure is a front view of the same as above, in which a lateral movement device 5 using, for example, hydraulic pressure as a drive source is provided across the width direction at the front end of a self-propelled small trailer 1 as a dolly, and is attached to the lateral movement device 5 so as to be able to move laterally. A bracket 4 supports the lower end of a column 3 into which a sliding rod 2 is inserted from the upper end, a motor 23 provided below the column 3, a pulley 24 provided above the sliding rod 2 and the column 3,
25 are connected by a belt 26.

An arm 7 projects horizontally forward from the upper end of the sliding rod 2, and a pulley 27 is provided at the tip of the arm 7.
and a motor 28 provided at the base are connected by a belt 29, and the sliding holder 6 to the arm 7 is fixed to this belt 29.

The sliding holder 6 fixedly supports the rear part of the jet water nozzle 9 with a support bracket 8' projecting from the upper surface. Keep it movable.

On the other hand, a high pressure water generator 1 is installed on the trailer 1.
0, hydraulic system 11, water pump 12, water tank 13
The high-pressure water generator 10 and the jet water nozzle 9 are connected by a water pipe 15 via a plurality of swivel joints 14a, 14b, 14c, 14d, and 14e.

In the figure, reference numeral 16 denotes an operating rod, and reference numeral 17 denotes a driver's cab.

Above, an example has been described in which a small trailer 1 is used as a traveling device for an excavator, and all devices such as a high-pressure water generator 10 are mounted thereon. As shown,
A trailer 18 that does not have a mechanism for moving all the equipment
It may also be mounted on top and towed by a small crawler 19 or a wheeled vehicle 20.

In the case of large equipment, the entire equipment is mounted on the crawler 21, as shown in Figure 5, or
As shown in Fig. 6b, it is also possible to mount only the water tank 12 on a towable trailer 18, and mount other devices on a crawler 21 or a wheeled vehicle 22, and use these to tow the trailer 18. .

Next, to explain the usage and operation of the ones shown in Figures 1 to 3, in order to excavate rocks, concrete walls, etc., first drive and move the trailer 1 to the designated location, then turn it in the excavation direction, and then When the lateral movement device 5 is moved left and right, the support column 3 is moved parallel to the trailer 1 to the left or right via the bracket 4. The sliding rod 2 is caused to slide up and down from the support 3 by the action of the motor 23.

When the motor 28 is moved, the holder 6 slides on the arm 7 via the belt 29, and the water jet nozzle 9 also moves back and forth on the arm 7 accordingly. In this way, the vertical, longitudinal, and horizontal positional adjustment of the jet water nozzle 9 is performed.

At this time, the water pipe 15 is connected to the swivel joint 14.
a to 14e, the jet water nozzle 9
The adjustment can be carried out without any trouble because the jet water nozzle 9 is directed in the excavation direction and the high-pressure water generator 10 is
Excavation is performed by moving the nozzle 9 up and down, back and forth, and left and right while injecting high-pressure water sent from the ground.

As mentioned above, the jet water excavator of the present invention excavates with a water jet, so there is no vibration, no noise, and no dust is emitted.
It is possible to move in all directions, front and back, left and right,
It is possible to excavate a desired location freely and over a wide range, and it is also movable, which improves work efficiency. Moreover, among the movements of the nozzle, horizontal movement is performed by a lateral movement device via a bracket, vertical movement is performed by a sliding rod, and forward and backward movement is performed at the upper end of the sliding rod. Since this is done using an arm and a sliding holder, movement in the left/right, up/down, and front/back directions is performed by independent and separate mechanisms, allowing for fine-grained adjustments to be made depending on the situation on site. It is what it is.
