Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a device capable of driving in and out a pile, particularly a spiral pile used when constructing an agricultural greenhouse.

(Prior Art) Conventionally, all the driving and pulling-out work of the spiral pile were performed manually.

(Problems to be solved by the invention) However, in the past, since the spiral pile driving and pulling-out work were all performed manually, it is hard work, and the working posture is not favorable for safety and hygiene, and the driving and pulling-out work are also performed. There was a defect that it took a long time to put out the work.

In view of the above-mentioned conventional problems, the present invention solves the above problems and enables safe and light work, which can reduce labor, and which enables extremely quick driving and ejection work. To get a pile driving device.

(Means for Solving the Problems) As a means for achieving this, the present invention provides a handle for clockwise rotation and a handle for counterclockwise rotation provided on a handle with one end of the cable for clockwise rotation and the cable for counterclockwise rotation. A control lever for actuating the hydraulic pump / control valve is provided on the operation auxiliary metal fitting that is fixed and engages the other end of the cable with the fork, and the high pressure hose for right rotation and high pressure for left rotation are provided. Connect one end of each hose to the hydraulic pump, and connect the other ends of the high-pressure hose for right rotation and the high-pressure hose for left rotation to the hydraulic motor fixed to the seat plate of the handle, and also fixed to the rotary shaft of the hydraulic motor. A spiral pile is detachably attached to the chuck.

(Embodiment) An embodiment in which a specific configuration of the present invention is shown in the drawings will be described in detail below. (1) is a hydraulic unit mount on which the engine (2), rotary joint (3) and hydraulic pump are mounted. Install the hydraulic package consisting of the control valve (8) and the hydraulic oil tank (9). As is well known, this hydraulic unit rotates the engine (2) through a rotary joint (3) to drive the hydraulic pump. Hydraulic pump transmitted to the rotary shaft of the control valve (8). Control valve (8)
Is a hydraulic pump that sucks oil from the hydraulic oil tank (9).
The control valve (8) is made to pass through the circuit and the oil is again discharged to the hydraulic oil tank (9).

A hydraulic pump. Since the control valve (8) and the hydraulic oil tank (9) are conventionally known, detailed structure will be omitted. (10) (10) 'is an operation lever for right rotation and an operation lever for left rotation, which is pivotally attached (13) (13) to a mounting plate (12) (12) fixed to a handle (11). ), The mounting plate (12) (12) and the operation lever (10) (1) for rotation.
Install the ammunition (14) (14) between it and 0) ′. (15) (15) 'is a clockwise rotation cable and a counterclockwise rotation cable, one end of which is fixed to the clockwise rotation operation lever (10) and the counterclockwise operation lever (10)', and the cable ( Insert the other end of (15) (15) 'into the groove (19) (19) through the holes (18) (18) formed in the forks (17) (17)' and attach the stopper (20) to the tip of the groove. ) Fix (20). Reference numeral (21) is an operation assisting metal fitting, both ends of which are fixed to the forks (17) and (17) 'by the pins (22). A control lever (7) is attached to the operation assisting metal fitting (21), and the forks (17) (17) 'and the operation assisting metal fitting (21) swing left and right to operate the hydraulic pump. The control valve (8) can be switched. (23) (2
3) ′ is a high-pressure hose for right rotation and a high-pressure hose for left rotation, one end of which is connected to the hydraulic pump (8) and the other end of which is fixed to the seat plate (11) ′ of the handle (11). Connected to the hydraulic motor (24). Also the rotary shaft of the hydraulic motor (24)
Fasten the screw (26) to the spiral pile chuck (26) with a set screw (27), and insert a groove into the inner wall of the spiral pile chuck (26) to tightly fit the upper end of the spiral pile (28). Engrave in a letter shape. Note that (22) indicates a cable pedestal.

Since the present invention is configured in this way, the upper end of the spiral pile (28) must first be checked before the spiral pile (28) can be driven into the ground.
After tightly fitting it in the groove of (26), and then turning the operating lever for right rotation (10) counterclockwise against the ammunition machine (14) while standing (see FIGS. 3 and 4). ), One end of the cable for right rotation (15) is pulled counterclockwise, and the stopper (20) fixed to the other end of the cable (15) operates on the operation support metal fitting (21),
Tilt (21) and control lever (7). Hydraulic pump by tilting the control lever (7). The control valve (8) is activated, pressure oil is sent from the hydraulic pump to the hydraulic motor (24) through the high pressure hose (23) for clockwise rotation,
The hydraulic motor (24) rotates clockwise. This Hydraulic Motor (24)
The clockwise rotation of the chuck causes the chuck (26) to rotate clockwise, and the spiral pile (28)
Is driven right into the ground while turning right.

The oil discharged from the hydraulic motor (24) passes through the control valve (8) and returns to the hydraulic oil tank (9).

Next, to remove the spiral pile (28) that was driven into the ground,
Tightly fit the upper end of (28) into the groove of check (26), and then
When the left-hand operation lever (10) 'is turned counterclockwise against the ammunition machine (14) while standing (see Figs. 3 and 4), one end of the left-hand rotation cable (15)' Is pulled counterclockwise,
The stopper (20) fixed to the other end of the cable (15) 'operates on the operation assisting metal fitting (21) to tilt the operation assisting metal fitting (21) and the control lever (7). Hydraulic pump by tilting the control lever (7). The control valve (8) is actuated, and the pressure oil is sent from the hydraulic pump to the hydraulic motor (24) through the counterclockwise high pressure hose (23) ', and the hydraulic motor is rotated counterclockwise. By turning the hydraulic motor (24) counterclockwise, the check (2
6) rotates counterclockwise, and the spiral pile (28) can pull out from the ground while turning left.

(Effects of the Invention) As described above in detail with respect to the embodiments, the present invention enables the work to be performed while standing while driving and pulling out the spiral pile, which is lighter than the conventional manual driving and pulling work. The work can be done easily and the labor can be reduced, and the safety during work can be secured. Furthermore, the present invention has an excellent effect that the work efficiency can be remarkably improved because the spiral pile can be driven in and out smoothly and smoothly by the operation lever and the hydraulic mechanism.
