Description

[Detailed description of the invention] The present invention relates to a working machine for a hydraulic excavator in which a boom and an arm are operated by a hydraulic cylinder.
The purpose is to enable the boom, arm and packet to support the boom cylinder, arm cylinder and bucket I-cylinder located along the frame and arm, thereby supporting the boom, arm and packet, as well as the boom, arm, It is an object of the present invention to provide a working machine for a hydraulic excavator that facilitates assembly and disassembly of a packet.

The configuration will be explained below based on the embodiment shown in the drawings.

In the figure, 1 is an upper revolving body mounted on the traveling device 2 so as to be able to rotate, 3 is a boom provided on this so that it can be raised, and 4 is a boom 3
The arm 5 is connected to the tip of the arm 4, and 5 is a packet connected to the tip of the arm 4.

6 is a boom cylinder whose one end is pivotally connected to the upper revolving structure 1 and the other end is connected to the boom 3 and runs along the boom 3; 7 is a boom cylinder whose one end is connected to the boom 3 and the other end is connected to the arm 4 and runs along the boom 3. Arm cylinder, 8, has one end attached to arm 4 and the other end attached to bucket l-
5 and along the arm 4;
These cylinders are arranged so as to be able to swing along the lower surfaces of the boom 3 and the arm 4, respectively.

Each of the cylinders 6, 7, 8 can be connected by links 9 to the boom 3 and arm 4 along which they lie.

FIGS. 2 and 3 show an example of a connection structure using the link 9. A bracket 10 is provided on the boom 3, and a bracket 11 is provided on the cylinder, and both brackets l-
10 and 11 are detachably connected by a link 9 and a pin 12.

Note that this link 9 may be constituted by a turnbuckle 13 as shown in FIG.

In the above configuration, when assembling the boom 3, arm 4, and packet 5, the cylinders along them are connected by links 9.

In this way, each cylinder is integrated with the boom 3, arm 4, and there is no need to support the cylinder separately, making it extremely easy to handle each cylinder when assembling the work machine. This eliminates the need for operations such as lifting a crane or moving cylinders in and out for hole alignment when connecting the booms 3, arms 4, and packets 5, making it easier to assemble and disassemble the boom 3, arm 4, and packet 5.

Further, according to the present invention, brackets 1 to 1 are provided on the lower surfaces of the boom 3 and the arm 4, and on the cylinders facing thereto, respectively.
0.11, and each of these brackets h 10
．． By removably connecting a link member such as the link 9 or the turnbuckle 13 between the cylinders 11 and 11, each cylinder is suspended and supported by one link member.
With an extremely simple configuration, you can safely attach the cylinder to boom 3.
It can be held on the arm 4 side.

Note that the link 9 should be removed after the assembly is completed.
