Claims

[Scope of utility model registration request]

(1) A supporting means for clamping the steel sheet pile, a mounting means for mounting the supporting means on a packet of an excavator, etc., and the supporting means are connected to be rotatable around a vertical axis with respect to the mounting means. The supporting means has a generally inverted U-shaped supporting means main body having a vertically extending opening that receives the upper end of the steel sheet pile from below, and a leg portion on one side of the opening. an aperture adjustment means for adjusting the aperture size by adjusting the aperture size; and a connecting pin fitted into the lower end of the rotating shaft, the pin being movable in the vertical direction above the aperture within a predetermined range with respect to the main body. a guide means for guiding, and a support that is linked to the connecting pin and projects into the opening when the rotating shaft is pulled upward with respect to the main body to sandwich the steel sheet pile between the opening adjusting means. an interlocking support means having a member; a latch means for restraining the interlocking support means in a position where the support member is retracted from the opening; to prevent relative inclination between the main body and the copper sheet pile,
A pair of wing parts extending on both sides of the main body so as to disperse the pressing force against the steel sheet pile during driving, and a communication hole arranged at the upper end of the main body to receive the rotation shaft,
The mounting means has a receiving plate portion extending in the horizontal direction that comes into contact with the mounting means, and the mounting means has a mounting portion for attaching to a packet of an excavator, etc. at its upper end, and an upper end of the rotating shaft at its lower end. 1. A lightweight net sheet pile driving/pulling jig suitable for mounting on an excavator J', characterized by having a bottom plate part having a hole for receiving the part and a bottom plate part rotatably supporting the part around a vertical axis.

(2) The rotating shaft has a male-threaded head at the upper end, and the mounting means and the rotating shaft are connected by being screwed into a nut above the bottom of the mounting means. The jig according to item 1 above.

(3) The rotating shaft has a head that is inserted into an upper hole of the bottom plate of the mounting means and supported on the bottom plate, and is thereby rotatably connected with respect to the mounting means. The jig described in Section 1.

(4) A thick washer is provided on the upper side of the bottom plate of the mounting means to disperse the pull-out load acting between the nut or head of the rotating shaft and the bottom plate. The jig described in paragraph 2 or 3.

(5) The lower portion of the rotating shaft has at least a pair of parallel side surfaces that slide against opposing inner walls of the main body, thereby limiting play between the rotating shaft and the main body in at least one direction. Item 1 above, characterized in that
The jig described in any one of paragraphs 4.

(6) Items 1 to 1 above, wherein the guide means is a vertically extending groove or slit formed in the opposing inner walls of the main body, and both ends of the connecting pin are guided so as to be movable in the vertical direction. A jig as described in any one of Item 5.

(7) The interlocking supporting means includes a supporting member pivotally mounted in proximity to the lower end of the other leg, and a link arm connecting the supporting member and the shaft pin at the lower end of the rotating shaft. , wherein the supporting member has an eccentric cam surface such that when the rotating shaft is pulled upward with respect to the main body, the protrusion of the supporting surface into the opening increases. The jig described in any one of paragraphs 6.

(8) The latching means includes a latch arm pivotally mounted at one end on the main body above the supporting member, the free end of the latch arm engaging a portion of the connecting gripping means to engage the supporting member. Any one of the above items 1 to 7 that restrains the eccentric cam surface from protruding into the opening.
Jig described in section.

(9) A biasing means is provided between the latch arm and the supporting member, and the eccentric cam surface of the clamping member is in an inoperative state at a position retracted from the opening, and the latch arm is rotated. 9. The jig according to item 8, wherein the jig is activated when the supporting member is biased in a direction that causes the eccentric cam surface of the supporting member to protrude into the opening.

(10) A hook is formed above each of the pair of wing parts, and the hook functions as a reinforcing member against the driving load of the wing part, and can be used for suspending various materials. The jig according to any one of the above items 1 to 9.
