Abstract

The present invention relates to a lift type high-place working device. The lift type high-place working device is structured to have an overall low profile structure due to a main treadboard, which is made thin. Therefore, the lift type high-place working device can prevent a worker from damaging or interrupting branches hanging down from fruit trees around the worker at a lower place as well as fruits in the branches, when the worker moves along a working passage in an orchard or a greenhouse. The lift type high-place working device comprises a rail transfer car, which has two caterpillars; a transfer car frame, which is mounted on the rail transfer car; an X-shaped link, which is installed to be folded or unfolded in the upper part of the transfer car frame by a lift cylinder; the main treadboard, which is a worktable in the lift type high-place working device including the worktable installed to be lifted by the X-shaped link; a secondary left treadboard, which is installed to be drawn in and out from the left side of the main treadboard; and a right secondary treadboard, which is installed to be drawn in and out form the right side of the main treadboard. The main treadboard has an accommodation space, which the secondary left treadboard and the right secondary treadboard are drawn in. When the secondary left treadboard and the right secondary treadboard are drawn in the accommodation space of the main treadboard to be accommodated, the secondary left treadboard and the right secondary treadboard move at the same height level. Therefore, the secondary left treadboard and the right secondary treadboard are not installed not to be overlapped.

Description

[0001] LIFT TYPE HIGH-PLACE WORKING APPARATUS [0002]

More particularly, the present invention relates to a high altitude work device, and more particularly, to a high altitude work device having a thin thickness of a main tender plate and having a low profile structure as a whole, And more particularly, to a lift-type high-performance working apparatus capable of damaging fruit or preventing interference, as well as having a side-to-side power.

Generally, an agricultural high-altitude working apparatus used in an orchard or a house is used for carrying out a high altitude work in which a worker is difficult to work while standing, for example, pruning of fruit trees and fruit harvesting. Such a high-altitude working device is provided with elevating means for simply raising and lowering the vehicle or truck having the moving and stopping means. In addition, the worker can be raised in a state where the worker is aboard the workbench, and work at a high position can be easily performed.

Such a high-lift work apparatus can be realized in various ways such as a boom type in which one or more booms are vertically rotated to elevate and descend the work platform, and a lift type in which the work platform is raised and lowered by the elevation operation of the X-shaped link .

Among them, the general structure of the lift type elevating work device includes a frame having an infinite orbit, and an X-shaped link provided on the upper portion of the frame for elevating and lowering the work table as it is folded or unfolded by the lift cylinder. The workbench includes a main bushing and auxiliary bushes on both sides of the main bushing installed on both sides of the main bushing.

Meanwhile, in the conventional lift type high-lift working apparatus, the auxiliary boards of the workbench are provided in a state where they are overlapped with each other at the lower portion of the main board, so that the width of the work board is increased to 2 to 2.2 times of the width of the main board when the auxiliary boards are drawn to be.

However, since the workbench is mounted on the lower part of the main board and the auxiliary boards on both sides are installed on top of each other, the workbench is inevitably thick. When the workbench is made thick, the height of the workbench mounted on the X- There is a problem in that it is inevitably provided with a high profile.

In this case, when the elevation table of the elevation apparatus is high, it is not possible when the interval between the fruit orchards and houses is wide, but when moving along the narrow working distance between the fruit trees, There is a problem that it leads to the damage of the orchard farmhouse.

In addition, in order to reduce the damage to a minimum, the worker who is aboard the workbench may move the workbench by carefully pushing the fruit or fruit without touching the outer edge of the workbench, but this has the disadvantage that the work can not be done efficiently.

In addition, a conventional lift type high-performance working apparatus is provided with a plurality of left-and-right rotating cylinders for pivoting the frame to the left and right corresponding to the left and right tilts of the work surface of the orchard work, (Four in total) are installed symmetrically on both sides of the frame, the left and right pivoting cylinders are excessively inserted, and the cost of the left and right pivoting cylinders is increased.
