Description

[Detailed description of the invention] Industrial application field This invention relates to a positioner that is equipped with a self-propelled elevating work platform and a trolley for transporting objects to be processed.

Conventional technology In welding work and other cases where the workpiece is processed directly by hand by a worker, the workpiece is heavy and the work cannot be done while the workpiece is placed on the floor. If this is difficult, usually
The work is carried out by placing the workpiece on a workbench called a positioner.

This positioner comes in various shapes, but one example, as shown in Figure 3, is one in which a sliding frame is fitted into two left and right posts protruding from the floor so that they can slide up and down. A support frame is attached between the left and right sliding frames, a turntable is attached to the support frame, and the sliding frame is pulled up by a winch installed at the top of the post. When performing machining work, the workpiece is mounted on a turntable, the sliding frame is raised and lowered with a stool, and the support frame is adjusted to an easy-to-work position. A workbench was used, and work was done by climbing on the workbench. This workbench can either be installed directly on the floor or have wheels that allow it to be moved freely. He was working upstairs.

Further, in order to transport the workpiece to the position of the turntable, a forklift, an overhead crane, or the like is used, and no special dedicated transport device is used.

Problems to be solved with the invention: When the workpiece is not very large, the above positioner allows the operator to go to the most suitable position for the work by raising and lowering the support frame and using a separate workbench. , When the workpiece is large, there is a limit to the position of the support frame.
In addition, since there are many parts to process, it is difficult to leave the workbench in one place while the worker gets off the workbench and moves it to another place.
He also used the method of climbing up and doing the work. Moreover, the height of the workbench is fixed, and if you want to work at a higher position, you have to add an additional workbench or use a separate, higher workbench.

Furthermore, since a forklift or other transport vehicle must be used to transport the workpiece to the positioner, there is a concern that the work may not progress as planned if it conflicts with other work processes. Ta.

This invention was devised in view of the above points, and aims to provide a device that can achieve ease, speed, stability, etc. of work by combining a positioner, a workbench, and a transport vehicle. The purpose is to

Means for Solving the Problems The means of this invention taken to solve the above problems are as follows: (a) The positioner device with a self-propelled lifting work platform of this invention has two posts on the left and right that protrude from the floor. On the other hand, a sliding frame is inserted so that it can be raised and lowered,
A mobile work vehicle is provided with a support frame having a turntable attached between the left and right sliding frames to form a positioner, a plurality of sets of rails are laid facing the positioner, and a workbench is provided on each rail; A positioner device on which a cart for transporting a workpiece is placed, and (b) a plurality of posts are provided protruding from the lower platform of a mobile work vehicle having wheels, and each slides on the posts so as to be able to rise and fall freely. A frame body is inserted and connected through each sliding frame frame, and a work platform is installed on the frame, and (c) a lifting mechanism is provided between the frame and the lower platform, and a lifting mechanism is provided between the frame and the lower platform, and The lower part was configured to allow a trolley for transporting the workpiece to pass through.

Effects of the invention As mentioned above, the present invention has a positioner that can attach a workpiece and can freely raise and lower it, a worktable whose height can be freely adjusted with a lifting mechanism, and a movable table that can freely move in the direction of the positioner. Since it is composed of a work vehicle and a trolley for transporting the workpiece, the position of the workpiece and the worker can be freely adjusted during welding and other processing operations on the workpiece.
The worker can work in a comfortable posture.

In addition, conventionally, the user had to repeatedly get off the workbench, move the workbench, and then climb up on the workbench every time the work position changed, but this is no longer necessary, reducing fatigue and improving work efficiency. . Further, since the workpiece transporting cart passes under the mobile work vehicle, the workpiece can be easily transported to the turntable side. At the same time, the area required for installing the positioner device with the self-propelled lifting workbench can be set to a minimum, so the space within the factory can be used effectively.
