Description

Driving {PILE DRIVER}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a navigator for carrying out a helm operation by raising and lowering a work device along a leader mounted on a base machine.

The cruiser is guided to the base machine, a leader mounted on the front of the base machine so as to be capable of ups and downs, a backstay supporting the leader from the rear of the base machine, and a guide pipe installed at the leader. The lifting device includes a work device such as an auger driver. Further, the base machine is provided with a plurality of winch drums wound by winding wire ropes for lifting and lowering the work device, up and down of the work member, and ups and downs of the leader. The wire rope from each winch drum passes from the lower guide sheave installed at the front of the base machine to the top sheave block at the top of the leader via a suspension guide sheave disposed behind the leader's middle. It is wound around the upper guide sheave arrange | positioned at the block) (for example, refer patent document 1).

Japanese Unexamined Patent Publication No. 2010-13814

For example, in the case of a conventional cruiser provided with four winch drums, the stop guide sheave is a first wire rope (main rope) from a first winch drum (main drum) which is a main winch drum. Was wound around the first guide sheave provided independently, the second to fourth wire ropes from the second to fourth winch drums are the second to fourth guide sheaves arranged side by side in the left and right direction on one attachment shaft. It was wound up. For this reason, when the winding position to the upper guide sheave of each wire rope wound on the 2nd to 4th guide sheaves was changed by work content, wire ropes might mutually interfere and mutually interfere.

Therefore, an object of the present invention is to provide a navigator which does not interfere with wire ropes even when the winding position from the interruption guide sheave to the upper guide sheave is changed.

In order to achieve the above object, the anti-taking device of the present invention includes a lower guide sheave provided at the front of the base machine and a height of the leader installed at the front of the base machine, with each wire rope from the plurality of winch drums mounted on the base machine. In a driving ride wound around a suspension guide sheave arranged at the rear of the direction stop and an upper guide sheave arranged at the top sieve block provided at the upper end of the leader, the plurality of winch drums are provided with a long wire rope. A plurality of long winch drums wound by winding a plurality of long winch drums wound by winding a short wire rope, and the stopper guide sheave has a guide sheave attachment shaft facing the axis in a left-right direction. Longitudinal guide sheave and the shortened wire for guiding the long wire rope together with a plurality of installations Guide dancheok sheaves for guiding the rope is characterized in that attached to the sheave attached to the same guide shaft and attached to each other guide sheave for the long and the other guide sheave mounting shaft with each other for the guide sheave dancheok.

According to the navigator of the present invention, since the wire ropes of the same length are guided by the interruption guide sheaves separated in the front-rear direction, the wire ropes intersect when the winding positions of the wire ropes of the same length to the upper guide sheave are changed. Even if it becomes a state, it will not interfere with each other. In addition, since it is not normally performed to change wire ropes of different lengths, there is no problem even if wire ropes of different lengths are arranged side by side on one guide sheave attachment shaft.
