JPH02193888A - Opening and closing body structure having rotatable holding folk body - Google Patents

Abstract

PURPOSE:To enable the rotation of a substance supported between folk parts by disposing an opening and closing body below a rotating body mounted to a body mounting chassis, and providing a positional hydraulic motor for opening and closing the folks of the opening and closing body on the rotating body. CONSTITUTION:One end of a rotating body 1 having one end mounted to a body mounting chassis 5 is mounted to the arm body of the chassis 1 so that the rotating body 1 can be inclined. The folks 19, 20 of an opening and closing body 18 are opened and closed by a positional hydraulic motor 17 on the rotating body 1 through an oil pressure hose 10 and a hydraulic cylinder 21. A substance supported between the folks 19, 20 is rotated by the inclination of the rotating body 1. Further, a tool such as machine drill, breaker, and chain sow is properly fixed by an attachment mounting means 345 provided on the folk parts 19, 20 and used.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an opening/closing structure having a pivotable gripping fork body, and particularly to an opening/closing structure suitable for use while being supported by a support member of a power shovel or the like. In the past, attempts have been made to attach functional components such as excavators to the tip of the support components of construction machines such as power shovels to perform various functions, but these functional components may only have a single function. However, it has the drawback that it is only capable of achieving extremely limited functions and is not suitable for performing complex functions or requiring multiple functions. The present invention aims to eliminate the above-mentioned drawbacks.

Next, a specific configuration for achieving the above object will be described with reference to the drawings. The swivel joint is located at the tip of the main body mounting chassis 5 between the rotating body mounting parts 8 disposed on the upper part of the rotating body 1. 6, a swivel joint stopper 7 is arranged at both ends of the swivel joint 6, and a rotor attaching part 7 is provided on the opposite side of the swivel joint stopper 7 of the rotating body attaching part 8. 2, a shaft 4 is provided protruding from the rotating body mounting portion 2, a projecting object mounting portion 3 is provided at the other end of the shaft 4, and the projecting object mounting portion 3 and the main body mounting chassis 5 are connected as appropriate. A telescopic member (not shown) is disposed with an arcuate connecting body interposed between the main body mounting chassis 5 and the main body mounting chassis 5, one end of which is supported at an appropriate position, and the other end of which is located at the removable body mounting portion. .

The swivel joint 6 is provided with a hydraulic oil inlet/outlet 9,
One end of the hydraulic hose lO is connected to the swivel joint 6, and the other end is connected to the hydraulic motor 17, and the other swivel joint 6 and rotary joint 16 are also individually connected by the hydraulic hose 10, and the rotary The joint 16 and the hydraulic motor 17 are arranged at the center of the rotating body 1, and a disc brake lock part 15 is provided on the circumference of the rotating body 1, and a waterproof cover seal is installed at an appropriate position on the rotating body 1. 12.13.14, a waterproof cover 11 is provided above the rotating body l, an opening/closing body 18 is provided below the rotating body l, and the opening/closing body 18 is disposed on the lower surface of the opening/closing body 18 facing downward. The first fork 19 and the second fork 20 are positioned so that the lower end position of the parallel wing piece is held between the opposing members at the upper end thereof, and the first fork stopper pin 27 is used to secure the first fork at the upper end position of the first fork 19. 19, and a second fork 20 located at its working end.
A hydraulic sill 21 is interposed between the second fork stopper 23 and the second fork 20, and the hydraulic cylinder is installed at a position opposite to the second fork stopper 23. A second fork locking pin 22 is provided via the cylinder 21, and the position of the stop portion 25 of the second fork starting shaft 24 is at the position of the starting shaft stopper boss 26, thereby opening and closing the second fork turning shaft 2o. The angle can be changed, and the second fork starting shaft 2
4 by placing the second fork starting shaft stopper 25 in the position of the start shaft stopper boss 26 and by attaching the start shaft stopper 28 of the second folded start shaft 24 to the start shaft stopper boss 29.

By changing the opening/closing angle and opening/closing force of the second fork 20 and removing the starting shaft 24, the starting shaft stopper boss 29 and the chassis boss 34 can be locked with a pin, or the starting shaft stopper 28 and the chassis boss 34 can be locked together. By locking with the bottle, the second fork 2
0 can be fixed, the second fork 20 can be fixed and the first fork 19 can be operated so that it can be held between the first fork 19 and the second fork 20, and the first fork 19 and the second fork can be held together. 2. An attachment mounting boss 35 and an attachment mounting hook 3 are installed near the mounting position of each fork member with the fork 20.
6, iron plate parts 31, 32, and 33, which are attachment parts for the iron plate packet body, are provided at appropriate parts of the opening/closing body 18, and anti-slip parts are provided near the tips of each of the first fork and the 27th fork. This is an opening/closing structure having a pivotable gripping fork body provided with a portion 37. Next, to describe the effects resulting from the above configuration, since it consists of a rotating body and an opening/closing body, it is possible to rotate an object held between the fork parts attached to the opening/closing body. Also, one fork part is fixed and the other fork part is moved to have the effect of holding and holding various objects. In addition, the attachment mounting means provided on the fork allows you to secure various tools such as rock drills, pre-cars, chainsaws, vibrators, grass mowers, block clippers, hump pipe clippers, U-shaped groove clippers, and other tools. It has a vine effect.
