Description

Detailed Description of the Invention (Industrial Field of Application) The present invention is directed to a pile that is self-propelled on an existing pile row and transports various materials, and that is capable of carrying out piling work by attaching various working devices to the upper part of the pile. The present invention relates to a method for moving an upper working device on a desk, a pile clamping mechanism, and a pile clamping method.

(Prior art) Pile lifting equipment includes pile press-in and pull-out machines that continuously press in and out piles, working machines that carry cranes and the like to perform various tasks, and mobile devices that transport piles, materials, etc. . In both cases, predetermined work is carried out while moving over rows of existing piles that have been continuously driven.

These pile working devices are equipped with a plurality of clamping mechanisms such as clamps and chucks, and the working device moves on the core while one of the clamping mechanisms clamps the existing pile and maintains supporting force. As shown in FIG. 6(A), this clamping mechanism has clamping claws 51.5 that are horizontally movable in a direction perpendicular to the existing pile row.
It was composed of 2. The clamping claws of this clamping mechanism were operated as described above.

First, the clamping claws 51 and 52 move horizontally in a direction orthogonal to the pile row to clamp the existing pile F). For example, in the case of steel sheet piles, the web is moved orthogonally to the web to clamp the web.

Next, the operation to move in the vertical direction. For example, when the working device moves forward on a row of piles, first release the clamping state of the clamping claws 52 from the existing pile 1) 12, and then
Increase by 1 in the direction of the arrow. And after the advancement of the working device,
The clamping claws 52 are lowered again to clamp the existing pile P l 3. Then, use the clamping claws 52 to attach the pile 2 working device to the existing pile P13.
6(C), the clamping claws 51 are raised by the width of the pile and then lowered to clamp the existing pile 12 with the clamping claws 51. Such vertical movement prevents the clamping claw from colliding with the existing pile.

By repeating the above operation 1-, the pile-up working device grips the upper end of the existing pile row and moves on its own.

(12 Problems to be Solved by the Invention) However, in the above-described clamping method and pile 1 moving method, the entire clamping claw must be moved 1 Y1 during stacking and movement, resulting in poor work efficiency. In addition, if there was an obstacle above the existing pile, the two parts of the pile working device could collide with the obstacle, making the work impossible in some cases. In addition, since the cylinder mechanism for operating the clamping claws is installed internally, the clamping mechanism becomes thick and the work equipment [
a became heavier.

The present invention eliminates the above-mentioned problems, and even if there are obstacles at the upper end of the existing pile, it can clamp and release the existing pile, and the device can move the granular soil quickly and reliably. The purpose of this invention is to provide a method for holding a pile.

(Means for solving the problem) To solve the above problems, 1. 2. Pile 1 - Moving method of the present invention is to clamp the upper end of the existing pile with the clamping claws at the front and rear ends of the main body frame and the clamping claws of the longitudinal moving body, place the working device on the pile row, and then place the working device on the pile row, and then use the clamping claws of the longitudinal moving body to clamp the upper end of the existing pile. The nails are rotated in a direction perpendicular to the row of piles to release the clamping state of the piles and move the longitudinal moving body forward. After moving, the upper end of the pile is again clamped with the clamping claws of the front and rear moving body.

Next, the clamping claws of the main body frame are rotated in a direction perpendicular to the row of piles to release the clamping state of the piles and move the main frame forward, and then the upper ends of the existing piles are clamped again by the clamping claws.

Further, the pile holding mechanism has a pair of holding claw opening/closing mechanisms attached to both sides of the support member of the pile-up working device, and the holding claws are rotatable at one end of the opening/closing mechanism in a direction perpendicular to the pile row. The pile clamping method is characterized by operating a pair of clamping claw opening/closing mechanisms configured on both sides of the pile working device, rotating the clamping claws in a direction perpendicular to the pile row, and pressing the pile surface from both sides. shall be.

(Function) The upper end of the existing pile is clamped by the clamping claws of the support section attached to both ends of the main body frame and the front and back moving body, and the pile-up working device is fixedly held on the existing pile.

When moving the pile work device over the row of piles, the clamping claws of the front-rear movable body clamp the pile, and the clamping claws at the front and rear ends of the main body frame are released to move the main frame forward. After the movement, the stake is again clamped by the clamping claws on the main body frame, and the clamping claws at the bottom of the front-rear movable body are released to move the front-rear movable body forward to clamp a new pile.

By repeating the above operations, the pile 1-working device moves forward on the desk.

In the pile clamping action described in L, each clamping claw moves in the left-right direction (direction perpendicular to the pile row) centering on each support and both ends of the support part.
Because of the rotational movement, the existing pile can be released and clamped without colliding with obstacles near the existing pile.

Furthermore, when moving the pile 2 working device forward or backward, the entire clamping claw is
Since there is no need to move the device downward, even if there are obstacles above, part of the device will not come into contact with them. In addition, the efficiency of the work, which takes time and effort when moving the device forward, is improved.

Note that FIG. 5 shows another pile-up working device B used in the present invention, and is a sectional front view of the pile-up working device A corresponding to the line ■-■ in FIG. 1.

The length of the support part 31 of this pile-up work device B is shorter than that of the support part of the pile-up work device A, and the rod side end of the clamping claw opening/closing cylinder 33 is rotatably attached to both sides of the support part 31. It was installed on. The other configurations and functions are the same as those of the "Pile" 2 working device &A.

According to the pile work device B, since the length of the support part 31 is short,
It is possible to hold piles and move them over the core in narrower work sites.

(Effects of the Invention) As explained above, according to the pile clamping method and moving method of the pile working device according to the present invention, an existing pile can be safely and reliably clamped and released.
