JPS59138624A - Two-point slewing power shovel - Google Patents

Abstract

PURPOSE:To permit the parallel operation of a two-point slewing power shovel as well as raise its power by providing a slewing gear between a truck frame and a swing table and a slewing gear between the swing table and a operation seat by biasing their central axes. CONSTITUTION:An exclusive gear B for a boom E and an operator room F is attached to the upside of the swing table C of a power shovel in such a way as to enable the boom E and the operator room F to be turned independently. A slewing gear A between a truck frame G and the slewing gear B are provided at an interval enough to avoid the lapping of their slewing centers. In case where trenching is made in the left-handed shoulder, for example, the slewing gear A is turned 90 deg. to the left, the slewing gear B is turned 90 deg. to the right, and thereby the boom can be moved to a desired position.

Description

DETAILED DESCRIPTION OF THE INVENTION (General description of the invention) The present invention is a conventional power excavator with a boom and a rotating gear dedicated to the driver's cab attached to the swing table.
This is a rotating power supply bell.

(Disadvantages of conventional technology) Conventional power excavators have a #maton that rotates in one place, making it difficult to perform tasks such as digging trenches on the edge of the road, and parallel work is even more difficult. ◇For this reason, although some parts of the boom and arm, etc. have been improved, the connection parts that should withstand the excessive weight originally required have been made weaker than before, resulting in a power/-1
High work efficiency could not be expected because the inherent durability of the bell would be reduced and its mobility would also be reduced.

(Purpose, structure, and effectiveness of use) This invention was devised for the purpose of eliminating the above-mentioned drawbacks, and a swing gear exclusively for the boom and operator's cab is installed on the swing lap of the conventional power excavator. It is mounted on a single board so that the chambers can move together and can rotate independently.

Therefore, the durability of the entire boom can be maintained at the same level as before, and since the driver's cab moves with the boom, it is easier to operate than before.Here, the truck frame and swing table A is the swing gear between the swing table and the driver's cab, and B is the swing gear between the swing table and the driver's cab.The position of the swing gear B is such that the center of the swing gear A and the center of the swing gear B do not overlap. is installed. By providing the swing gears in two places as described above, for example, when digging a trench on the left side of the road, the swing gear A can be rotated 90 degrees to the left, and the swing gear B can be rotated 90 degrees to the right. By doing so, the boom can be moved to the desired position, and the truck frame remains the same, making parallel work easier.
It enables greater mobility and higher work efficiency than ever before.
