Abstract

PURPOSE:To widen the range of operations as well as raise the traveling performance of a traveling type working platform by providing a plurality of leg column groups to be vertically operated. CONSTITUTION:Three leg columns 2a to be vertically operated are set, and the first body 1a having a rotary operating base 3 at the center and three leg columns 2b to be vertically operated are set. The second body 1b to be rotationally operated and moved back and forth is set by being incorporated to the first body 1a in a lapped manner. A relatively back and forth movable slewing mechanism 6 is set between the base 3 of the first body 1a and the second body 1b, permitting these bodies 1a and 1b to be directionally changed by mutual turning. The traveling performance as well as back-and-forth movability can be greatly raised, and the operating range can also be widened by turning operation. The operating performance of the traveling type working platform can be enhanced.

It has a structure in which it can be moved up and down and moved back and forth or left and right by a lifting and moving device (not shown). ) on the seabed (g), and while holding the main body (a), each pedestal (62) rises, and each carriage (c
, )t - moves backward and moves the main body (α) relatively forward, and when the carriage (cl) reaches the rearmost part of the well (dl), each pedestal (b2) k touches the ground and the main body ( ,
) 1 - Hold each pedestal (61) t - Rise from the seabed (gl, move to the leftmost part of the illustrated left side of each carriage (cl)''Ik well (dl), and then hold each pedestal (et)'e Touch the ground, each pedestal (b2) 'e rise to the main body (a) as above'
By repeating this operation to move the body further forward, the main body (al) moves forward, and by the same operation, it moves backward.
Furthermore, it is configured to allow walking operations such as moving to the left and moving to the right.

(Problems with the Prior Art) In the conventional walk-behind workbench, as shown in FIG. It is necessary to perform the entire rightward forwarding operation, or alternately repeat the backward and rightward forwarding operations, which requires many means and effort to walk diagonally, and the main body (α) cannot be rotated. 14
As shown in the figure, the work area is limited to the hatch area, and
Main body (a) where work equipment such as polling equipment is installed
) are moved and supported at the same time, and the center of gravity is shifted significantly relative to the support pillars, resulting in poor stability and the risk of falling.9
Furthermore, since at least six pillars, carriages, and wells are disposed over a wide range of the main body (cL) as shown in the figure, the effective space on the main body (G) is significantly limited. There are other problems.

(Objective of the Invention, Means for Solving the Problems) The present invention was developed to solve the above-mentioned problems. a first main body provided with a rotating operation table; and a second main body provided with at least three pillars that can be operated up and down, which are incorporated in an overlapping manner in the first main body and can be operated relative back and forth and rotated relative to each other. and the first and second main bodies disposed between the turning operation table of the first main body and the second main body.
The main body is characterized by a structure that includes a relative back-and-forth movement and rotation mechanism, and the first and second main bodies are provided with at least three pillars for lifting and lowering operations, and the entire relative back-and-forth movement and relative rotation. By assembling them in an overlapping manner so that they can be operated, and by arranging a rotating operation table and a relative back-and-forth movement/swivel mechanism between the first and second bodies, the first and second bodies can mutually rotate to change direction and move back and forth. This walking system significantly improves stability and walking performance, increases the space for placing work equipment on the main body, widens the working range by rotating the main body, significantly improves working performance, and solves the problems mentioned above. Provides a formal workbench.
