Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pile press-fitting / pulling machine which can automatically press-fit and pull-out a pile without an operator's operation.

[0002]

2. Description of the Related Art An anti-press-fitting / extracting machine presses an anti-force to construct a row of piles or to pull out the piles from the row of pits for dismantling while moving over existing piles. A conventional pile press-fitting / pulling-out machine is a manned device that is operated by an operator.

[0003]

In the conventional pile press-fitting / pulling-out machine, an operator is nearby to perform operations and commands, and since the operator is indispensable, unmanned operation cannot be performed. For this reason, it is not only necessary to pay close attention to construction on unstable ground or in dangerous places, but also the situation at the construction site,
There was an inconvenience that construction became impossible depending on the weather.
The present invention has been made in consideration of such circumstances, and by adopting a structure for automatically performing press-fitting and pulling-out of resistance, it is possible to unmanned and eliminate the inconvenience in a manned device. An object is to provide a pile press-fitting / pulling machine.

[0004]

The anti-press-fitting / extracting machine of the present invention which achieves the above-mentioned object is provided with an internal or external storage means in which information on press-fitting and pulling-out of a pile is recorded, and an anti-press-fitting and pulling-out machine for press-fitting and withdrawing the anti-pile. A pressure sensor that detects the closing pressure of the chuck that vertically moves by sandwiching, and a position sensor that detects the vertical position during pile press-fitting and pulling-out of the chuck, or a sensor that detects the thrust force during pile press-fitting and pulling-out,
It is characterized by further comprising control means for controlling the driving fluid pressure for opening / closing and vertical movement of the chuck on the basis of information from the external storage means and information from pressure sensors and other sensors. Further, the present invention is characterized by comprising recording means for recording data relating to press-fitting and pulling-out of the pile or control information of the control means in an internal or external storage means.

[0005]

The control means in the above construction judges the information from the pressure sensor and the position sensor of the chuck based on the information from the internal or external storage means, and outputs the control signal for the chuck to perform the optimum operation. The fluid pressure for driving the chuck is controlled by. Therefore, the press-fitting and pulling-out of the pile can be automatically performed. Further, the control signal output by the control means is newly recorded in the internal or external storage means by the recording means and utilized as information at the time of construction of the next stage.

[0006]

FIG. 1 shows a pile press-fitting / pulling machine according to one embodiment of the present invention. In addition, since pulling out of the pile is the reverse of press-fitting of the trough, and the basic operation is the same, the press-fitting of trough is described in the following description. The pile press-in / pull-out machine 1 in FIG. 1 moves a new pile PO while moving on the existing anti-P row pressed into the ground.
It is the one that press-fits and installs the anti-row. Therefore, the anti-press-fitting / pulling-out machine 1 has a plurality of clamps 2 for holding a plurality of existing piles P.
And a chuck 3 that chucks new piles PO and moves up and down.

A plurality of clamps 2 hang down from a saddle 4, on which a slide base 5 which is relatively movable for at least one pitch of the existing anti-P is mounted, and a mast is mounted on this slide base 5. 6 are erected. A guide rail 7 is provided on the front side of the mast 6, and the chuck 3 is attached to an elevating body 8 which slides vertically along the guide rail 7. The up-and-down movement of the lifting body 8 is performed by the main cylinder 9 driven by the fluid pressure, whereby a new anti-PO is press-fitted by the chuck 3.

Since the chuck 3 grips the new pile PO at two positions, the upper chuck part 31 and the lower chuck part 3
2, the pressures of the upper chuck portion 31 and the lower chuck portion 32 at the time of chucking are detected by the pressure sensors 33 and 34 arranged respectively. The chuck 3 also includes a pressure sensor 35 (see FIG. 2) that detects the pressure when the chuck portions 31 and 32 are closed. In FIG. 1, reference numeral 11 is arranged in the vertical direction of the mast 6, and a position sensor that indirectly detects the vertical position of the chuck 3 by detecting the vertical position of the lifting body 8, and reference numeral 12 is with respect to the vertical direction of the mast 6. It is a mast angle detection sensor that detects a tilt angle.

FIG. 2 shows a system configuration for automating the operation of the anti-press-fitting / withdrawing machine having the above configuration, and the elements corresponding to those in FIG. 1 are designated by the same reference numerals. In FIG. 2, reference numeral 1
Reference numeral 3 is a sensor that detects the closing pressure of the clamp 2 that clamps the existing anti-P, and reference numeral 14 is a receiver to which pile press-fitting commands and data are supplied by wireless or wire, and calculates information such as received commands and data. To the means 27. Reference numeral 20 denotes an IC card as an external storage means, in which information about anti-press-fitting such as a method of press-fitting a pile and its procedure and data at the time of press-fitting the pile is recorded.

The computing means 27 receives and stores the information regarding the anti-press fit recorded in the IC card 20 and the command and data sent from the receiver 14. Further, the calculation means 27 receives various data at the time of actual press-fitting of the piles from the above-mentioned sensors 33, 34, 11, 35, 13, 12. Then, based on these data and the information transmitted and stored from the IC card 20 and the receiver 14,
Calculate the optimum pile press-fitting conditions for on-site construction. Code 2
Reference numeral 8 is a control means for converting the pile press-fitting condition calculated by the calculation means 27 into a control signal and outputting the control signal. The control means 28 outputs a control signal to a solenoid valve 23 that controls the amount of fluid supplied to the main cylinder 9 that moves the chuck 3 up and down, thereby controlling the up and down movement of the chuck 3.
A control signal is output to a solenoid valve 22 that controls the amount of fluid supplied to a fluid pressure cylinder (not shown) that opens and closes the chuck 3 to control the gripping force of the pile. By these controls, the press-fitting of the pile can be automatically performed under the optimum conditions. Further, the control means 28 outputs these control signals to the recording means 21, and the recording means 21 records the control signals as control information in the IC card 20 or the internal storage means. As a result, new information regarding press-fitting of the pile is recorded and used for the press-fitting of the next pile and the like. Reference numeral 24 is an A / D for visually displaying the operation result of the operation means 27 and the control signal output by the control means 28 in the form of characters, numbers or figures.
It is a monitor.

In the above configuration, the various sensors 33, 34, 1
The computing means 27 calculates the optimum anti-press fit condition based on the data from 1, 35, 13, 12 and the control means 28 controls the vertical movement and opening / closing of the chuck 3 based on this calculated value. All of can be done automatically. For this reason, since it is possible to unmanned, it is possible to eliminate the inconvenience of the manned device.
