Description

[Detailed Description of the Invention] The present invention relates to a work vehicle in which a work platform with a driver's seat is attached to a wheel-type traveling machine platform so as to be able to rotate around a vertical axis.

Conventionally, a work vehicle equipped with this type of swiveling work platform has been constructed in such a way that the traveling machine platform side and the work platform are completely separated at a certain level in the vertical direction.

In other words, only the traveling equipment is placed on the traveling machine platform side, and the flat plate-shaped workbench that serves as the standard level is equipped with the control section and work equipment on the top surface so that turning work can be performed. It was composed of

In addition, there are two types of work vehicles: crawler type and wheel type, each of which has its own unique utility value. In order to prevent the extended axle from coming into contact with uneven ground, the minimum height of the vehicle body frame must be maintained above a certain level, so the wheel diameter cannot be made sufficiently small, and Since the workbench must be placed at the top of the track, the crawler wheels are mounted independently on the left and right truck frames, and the body frame is installed above the left and right truck frames. There is a tendency for the height above the ground of the swivel work platform to be higher than that of the above-mentioned reference level.

For this reason, the control unit disposed on the swivel table also becomes high, making it difficult to perform work in areas where the overall height of the aircraft is restricted.

The technical problem of the present invention is to devise a work vehicle in which a rotating work platform is mounted on a wheel-type traveling platform so that the height of the vehicle can be made even lower.

The technical means of this invention taken to solve the above problems are as follows:
This is a work vehicle in which a work platform with a driver's seat is attached to a wheel-type traveling machine platform so as to be able to rotate around the vertical axis, and a footrest for a driver sitting in the driver's seat is provided from the upper end of the wheel in a side view. It is also located below the wheel, and in a position where the turning locus does not overlap the wheel when viewed from above.

The effects obtained by taking the above technical measures are as follows.

That is, in general, when the traveling device is of the wheel type, a relatively large space surrounded by the wheels is created below the workbench, and a footrest for the driver seated in the driver's seat is inserted into this space. By lowering the footrest, the driver's seat level can be made as low as possible, and as a result, a swiveling work vehicle has been obtained that is configured to facilitate work in areas where the overall height of the machine is restricted.

Embodiments of the present invention will be described below with reference to illustrative drawings.

A turning race 2 is mounted on a machine base 1 equipped with a wheeled running device.
A fully rotating workbench 3 that can be freely rotated around the vertical axis by a hydraulic motor 12 is provided, and a control section 4 and a working device mounting bracket 5 that can be driven and swung around the vertical axis are attached to the workbench 3. A backhoe capable of digging side ditches is provided by attaching an excavating device to the bracket 5, which is constructed by attaching a packet 7 which can be driven and oscillated to the tip of a working arm 6 which is movable and movable and can be bent and extended. It is composed.

The operating section 4 is constructed by mounting a driver's seat 8 on the workbench 3 and providing a footrest 9 on which the driver seated on the seat 8 rests his/her feet when operating the work equipment.

The stress rest 9 is formed between the lower surface of the workbench 3 and the traveling machine base 1 by a turning race 2 and each wheel 10 that is mounted on the traveling machine base 1. A footrest support member 11 is made to protrude from the workbench 3 into an annular space A, and a footrest 9 is attached to the protruding end of the support member 11 within the space A.

When the footrest 9 is disposed in the space A, the footrest 9 is positioned below the upper end 10a of the wheel 10 in a side view, so that the installation level of the seat 8 can be made as low as possible. Also, in a plan view, the turning locus of the outer end of the footrest 9 corresponds to each wheel 10...
While maintaining the mounting level on the seat 8 by positioning the footrest 9 so that it does not overlap, that is, so that the outer end does not come into contact with the wheel 10 when the workbench 3 is turned. The workbench 3 is configured to be able to rotate.
