である。2. Description of the Related Art A vehicle body, a boom and a cylinder in a construction machine are constructed such that a boom rear shaft is pivotally attached to a vehicle body boom receiving shaft and a cylinder rear axle is pivotally attached to a vehicle body cylinder receiving shaft. The shafts are connected in an installed manner. When the cylinder expands and contracts, the boom swings around the boom receiving shaft. In such a construction machine, even if the vehicle body has the same purpose, the boom bearing shaft and the cylinder bearing shaft have different fitting relations, so that they can be connected to each other, that is, a general-purpose boom cannot be practically manufactured. Turning it over, even if there was a desired boom, it could not be connected and used unless the vehicle body was compatible.

する手段について、検討した。Although the vehicle bodies are used for the same purpose, manufacturing the booms for each vehicle body due to the difference in the connection relationship has pushed up the manufacturing unit price of the boom. Also, the fact that the boom is different for each vehicle body
This means that the boom that was connected to one vehicle body cannot be used by connecting it to another vehicle body. For this reason, when it is desired to temporarily use a different boom depending on the work content, the construction machine itself must be replaced. There is a problem that this brings unnecessary labor and effort. Therefore, in order to reduce the unit manufacturing cost of the boom, a means for connecting the booms for the same purpose to the vehicle bodies having different engagement relations while making the specifications of the boom rear axle and the cylinder rear axle common was examined.

A boom mounting shaft fixed to the receiving shaft and a cylinder mounting shaft fixed to the cylinder receiving shaft of the vehicle body, and a boom intermediate receiving shaft for pivotally mounting the boom rear shaft of the boom independently of the mounting shafts. It is a boom mounting adapter for a construction machine, which is provided with a cylinder intermediate bearing shaft that pivotally mounts a cylinder rear shaft of a cylinder.

For the boom and the cylinder, only the mounting relationship of the boom mounting shaft, the cylinder mounting shaft, the boom intermediate bearing shaft, or the cylinder intermediate bearing shaft with respect to the respective adapters may be considered. Thereby, the difference in the mounting relationship of the vehicle main body can be easily absorbed only by changing the mounting relationship of the cylinder or the boom with respect to the adapter.

Absorb the difference in the relationship. This means that the engagement relationship of the boom rear shaft or the cylinder rear shaft with respect to the vehicle body can be reset independently of each receiving shaft of the vehicle body.

る。[0007] As an application of the resetting of the above-mentioned relationship,
First, the axial distance between the boom intermediate bearing shaft and the cylinder intermediate bearing shaft is set shorter or longer than the axial distance between the boom bearing shaft and the cylinder bearing shaft. If the axial distance between the two intermediate bearing shafts of the adapter is shorter than the axial distance between the vehicle body receiving shafts, the boom lifting force (depression force) generated by the cylinder will be small, but the boom swing angle relative to the cylinder expansion and contraction amount Can be large. Conversely, if the axial distance between the two intermediate bearing shafts of the adapter is longer than the axial distance between the vehicle body receiving shafts, the boom swing angle with respect to the amount of expansion and contraction of the cylinder is reduced, and the boom lifting force generated by the cylinder (elevation Power) can be increased.
A smaller swing angle of the boom with respect to the amount of expansion and contraction of the cylinder means that the swing of the boom can be operated more finely.

中間受け軸は、ブームの偏位に応じて取り合い関係をず
らせばよい。Further, the resetting of the mounting relationship of each intermediate bearing shaft with respect to the vehicle body can be carried out by displacing the boom intermediate bearing shaft with respect to the boom mounting shaft to the left or right or up and down. If the fitting relationship between the boom mounting shaft and the boom intermediate receiving shaft is the same, the vehicle body can be connected to the boom and the cylinder without the adapter. Therefore, the adapter does not necessarily have the same fitting relationship. The deviation of the engagement relationship described above exceeds the disagreement of the engagement relationship of the adapter-specific engagement relationship and further shifts the engagement relationship of the boom intermediate receiving shaft with respect to the boom mounting shaft. For example, when a large boom swings, it may interfere with the driver's seat of the vehicle body. Therefore, the boom intermediate bearing shaft is displaced in the direction away from the driver's seat with respect to the boom mounting shaft. It suffices to shift the engagement relationship of the cylinder intermediate bearing shafts according to the displacement of the boom.

The cylinder mounting shaft 7 is fixedly attached to 14, the boom rear shaft 15 is mounted on the boom intermediate receiving shaft 4 of the adapter 1, and the cylinder rear shaft 16 is mounted on the cylinder intermediate receiving shaft 8 of the adapter 1. Figure 3
As is clear from the above, the adapter 1 of this example is
The axial distance between the boom intermediate bearing shaft 4 and the cylinder intermediate bearing shaft 8 is longer than the axial distance between the cylinder intermediate shaft 13 and the cylinder bearing shaft 14.
As a result, the lifting force (depression force) of the boom 2 attached via the adapter 1 is increased, and the swing angle of the boom 2 with respect to the expansion / contraction amount of the cylinder 17 is reduced, so that the boom 2 is reduced.
The swing of can be operated more finely. Thus, the adapter 1 of the present invention can change the characteristics in boom operation by changing the distance between the axes, and enables the same boom to be used properly according to the work.

Is a front view, the shift direction in the figure is opposite to that in FIG. 4. This misalignment of each axis when the boom 2 with a large diameter is attached
Make sure that the driver's seat 3 of the vehicle body 12 does not interfere with the boom 2. As in this example, each axis is configured with respect to the base 5.
Vehicle body side flange 9 , boom side flange 10 and auxiliary flap
The structure of the adapter 1 in which the lunges 11 are erected has an advantage that the structural strength is not impaired when the shafts are displaced in the left-right direction. As described above, the adapter 1 according to the present invention is originally used in the driver's seat 3
The boom 2 that cannot be used because it interferes with the vehicle body 12 is enabled.

The boom mounting adapter of the present invention (1) absorbs the difference in the engagement relationship with respect to the vehicle bodies having different engagement relationships, so that the same adapter can be used in each vehicle body, or (2) the same. It has a function to connect a boom that has a competing relationship that cannot be connected to the vehicle body. For example, by preparing adapters 19 and 20 that match a boom 18 and vehicle bodies 21 and 22, the same boom 18
