Description

Detailed Description of the Invention (Field of Industrial Application) The present invention has at least two clamps capable of clamping the upper end portions of existing piles made of steel sheet piles, etc., and both clamps alternately clamp the existing piles. The present invention relates to a self-propelled moving device that can load cargo and move on existing pile rows by moving the piles toward and away from each other.

(Prior Art) Materials, heavy objects, and other loads are sometimes transported and moved along rows of piles such as steel sheet piles buried underground at construction sites.

If the surrounding ground is leveled, various transportation devices such as trucks and loading machines such as cranes can be used.

(Problems to be Solved by the Invention) However, if the ground is not leveled or weak, it may become impossible to transport heavy objects to a predetermined location. Furthermore, it could not be used in muddy or muddy areas or in confined spaces.

Therefore, the object of the present invention is to have a small size, light weight, and good maneuverability.
A self-propelled moving device that can load heavy objects and move efficiently on its own without being affected by the ground conditions around existing pile rows, and is also capable of carrying work equipment such as cranes and shovels to perform various types of work. Our goal is to provide the following.

(Means for Solving the Problems) A self-propelled moving device according to the present invention for achieving the above object includes a base frame having a horizontal guide rail, and a vertical guide fixed to the front part of the base frame. a base having a guide head equipped with a rail; a base having a guide head provided with a rail; the base being slidably supported by the horizontal guide rail of the base frame body and reciprocally driven in the front and back direction by a horizontal reciprocating drive member; a horizontal movable body having a first clamp that can be clamped and fixed to the part; a horizontal movable body that is slidably supported on the vertical rail of the guide head and reciprocated up and down by a vertical reciprocating drive member; and a vertical movable body equipped with a second clamp that can be clamped and fixed to the upper end portion of the vertical movable body.

(Function) While the upper end of the existing pile is held by the first clamp provided at the bottom of the horizontal moving body and the entire device is held on the existing desk,
Drive the vertical reciprocating drive member to position the vertical moving body upward, and drive the horizontal reciprocating drive member to extend. Since the horizontal movable body is fixed to the pile by the first clamp, the base consisting of the base frame body and the guide head is pushed forward, and the vertical movable body supported by the guide head and the second clamp are placed above the pile in front. Move to. Then, the vertical moving body is lowered and the upper end of the opposing pile is clamped with a second clamp. Next, the first clamp is released, but since the base is held and fixed by the second clamp, stability is ensured. In this state, the vertical reciprocating drive member is driven to raise the base and the horizontal movable body relative to the vertical movable body fixed by the second clamp, and the horizontal reciprocating drive member is driven to shorten and move the horizontal movable body vertically. bring it close to the body.

When the first clamp is located above the column adjacent to the pile held by the second clamp, the vertical reciprocating drive member is driven to lower the base and the horizontal movable body relative to the vertical movable body.

Once the first clamp has inserted the opposing pile into the receiver, it will clamp it.

Thereafter, when the second clamp is released and the vertically moving body is raised, it returns to the initial state described above. Therefore, by repeating the above procedure, the device will move on its own over the existing pile row. It is also possible to retreat by performing the reverse procedure.

If heavy objects are loaded onto the upper part of the base frame, the cargo can be transported along the existing pile rows by the self-propelled movement of the device.

Furthermore, if work equipment such as a crane or shovel is mounted on the upper part of the base frame, it can travel to its destination and perform various tasks.

(Embodiment) The drawings show an embodiment of the self-propelled moving device according to the present invention, in which FIG. 1 is a side view, FIG. 2 is a front view, and FIG. 3 is a plan view.

1 in the figure is a base. This base 1 includes a platform 2 having a flat upper surface and sufficient length in the front-rear direction (left-right direction in FIG. 1), and a side wall 3 that hangs down from the side end of the platform 2.
It has a base frame body 4 consisting of 3. Said side wall part 3.3
Horizontal guide rails 5.5 extending in the front-rear direction are provided on the inner surface thereof in opposition to each other.

A substantially U-shaped guide head 6 is vertically fixed to the front part of the base frame 4. Vertical guide rails 8.8 are formed oppositely on the inner surface of the two sides 7.7 of the guide head 6.

10 is a horizontal moving body that can slide back and forth with respect to the base 1. This horizontal moving body 10 has a guide groove 1 which is slidably fitted into a guide rail 5.5 provided on the side wall 3.3 of the base 1.
1.11, with a guide rail 5.5 and a guide groove 11.11
By fitting, the base 1 and the horizontal movable body 10 support each other so as to be movable in the front and rear directions. In this embodiment, the horizontal guide rail 5 has a protruding shape, but of course the horizontal moving body 10
The above horizontal guide mechanism may be configured by providing a protruding rail on the side and forming a groove on the base 1 side to fit the protruding rail.

The horizontal moving body 10 has a first clamp 12 at the bottom. This first clamp 12 receives the upper end of a pile material such as a steel sheet pile, and clamps it using a suitable hydraulic system or the like.

Here, the first clamp 12 is rotatably provided,
- As shown by way of example, the rotational movement by the hydraulic motor 13 is transmitted to the clamping shaft 1 via a plurality of reduction gears 14,14.
5. This makes it possible to orient the clamp 12 in a desired direction by rotating the hydraulic motor 13 in any forward or reverse direction.

Reference numeral 16 denotes a horizontal reciprocating drive member consisting of a cylinder 17 and a rod 18 that can be driven to expand and contract by hydraulic pressure.

The cylinder 17 is fixed to the horizontal moving body 10 by the fixing member 19.
The rod 18 is connected to a bearing 6' fixed to the guide head 6 on the base side. Therefore, by driving the horizontal reciprocating drive member 16 to expand and contract, the horizontal moving body 10
is displaced in the front-back direction with respect to the base 1.

20 is a vertical moving body supported by the guide head 6. This vertical moving body 20 is provided with a guide protrusion 21.21 that is slidably fitted and guided and supported by a vertical guide rail 8.8 provided on the guide head 6. Here, the guide rail 8 is a groove and the protrusion 21 is a vertical guide mechanism in the form of a protrusion, but the groove and the protrusion may be configured in reverse.

A second clamp 22 is provided at the bottom of the vertical movable body 20, and can clamp the upper end of the pile by the same function as the first clamp 12.

Similar to the first clamp 12 in the horizontal moving body 10, the second clamp 22 is rotatably provided here as well. The rotational drive mechanism here is configured to transmit rotational motion by the hydraulic motor 23 to the clamp shaft 25 via a plurality of reduction gears 24, 24, and is similar to the rotational drive mechanism of the first clamp 12. , any configuration means may be used as long as the clamp can be rotated.

26 is a vertical drive member consisting of a cylinder 27 and a rod 28 that can be driven in the extension 11. The cylinder 27 is fixed to the guide head 6 by a fixing member 29, and the rod 28 is connected to a bearing part 20'' fixed to the vertically movable body 20.

Therefore, by driving the vertical reciprocating drive member 26 to expand and contract, the vertical moving body 20 is vertically displaced relative to the guide head 6.

The principle of movement of the moving device with the above configuration is shown in FIGS.
This will be explained below with reference to F).

FIG. 4(A) shows a state in which the entire moving device is fixedly held on an existing desk by both the first clamp 12 and the second clamp 22. In this first state, the second clamp 22 is clamped to the pile P2 adjacent to the pile P1 held by the first clamp 12. In other words, the horizontal reciprocating drive member 16
is in the shortened state, the distance between the horizontal moving body 10 and the vertical moving body 20 is relatively close, and the vertical reciprocating drive member 26 is in the extended state and the first and second clamps are positioned at the same height. There is.

Then, the second clamp 22 is released from holding the pile, and the vertical reciprocating drive member 26 is shortened to move the vertical moving body 20 as shown in FIG. 4(B).
raise it like this.

Next, the horizontal reciprocating member 16 is driven to extend to move the vertical moving body 20 forward (to the right in the figure) with respect to the horizontal moving body 10. As a result, as shown in FIG. 4(C), the second clamp 22 moves above the adjacent pile P3 in front of the counter P2. Then, the vertical reciprocating drive member 26 is activated to lower the second clamp 22. When the second clamp 22 receives the opposing resistor P3, the device is clamped and held (FIG. 4(D)).

In FIG. 4(E), the first clamp 12 is released, the vertical reciprocating drive member 26 is further driven to extend, and the base 1 and the horizontal movable body 10 are lifted above the row of piles. Therefore, the horizontal moving body 1 is shortened by shortening the horizontal driving member 11L.
0 to the front (Fig. 4 (F)). After that,
By shortening the verticality t1 of the driving member 26, the first clamp 12 receives the pile P2. This first clamp 1
The state in which the pile P2 is clamped and fixed in step 2 is the initial state shown in FIG. 4 (A), and the moving device can be moved by itself by repeating FIG. Become.

Further, backward movement can be achieved by performing the reverse procedure of the above-mentioned forward movement. The position and orientation of the second clamp 22 with respect to the first clamp 12 can be changed arbitrarily by driving a rotation drive mechanism consisting of a hydraulic motor 13.23 that rotates the first and second clamps, so that the pile row is curved. or
Or even if it is bent at right angles, it can easily pass through these parts.

(Effects of the Invention) As explained above, according to the self-propelled moving device of the present invention, the horizontal moving body is movable in the front-rear direction with respect to the base and has a first clamp, and the horizontal moving body is vertically movable with respect to the base. It has a vertical moving body that is movable in the direction and has a second clamp, and the first and second clamps can be moved up and down and back and forth with respect to each other, so they can move on their own on pile rows and carry heavy objects. It can be loaded and transported on pile rows. Furthermore, if a crane, shovel, etc. is installed, the machine can self-propel along the pile row to the destination and immediately perform the desired work. In this way, since the movable part is on a row of piles, it can be moved regardless of the leveling condition of the ground or the strength of the ground.Moreover, the device has a simple structure, is small and lightweight, and has good interlocking, making it easy to transport the device. It's easy. Also,
Since the first clamp and the second clamp are rotatable, it is easy to pass through even a portion where the pile row is arranged in a bent or bent shape.
