Description

[Detailed Description of the Invention] (Industrial Field of Application) This invention relates to a rotating device for a cabin of an industrial vehicle, and particularly to a rotating device for a cabin that aims to facilitate rotation and tilting of the cabin.

(Conventional Device) Conventionally, in a forklift truck equipped with a cabin, the cabin is usually located above the engine room.

(Problem to be solved by the invention) As mentioned above, the cabin is located above the engine room, so in the case of a fixed type cabin, the cabin becomes an obstacle when servicing the engine or replacing parts. This has disadvantages such as poor work efficiency and difficulty in inspecting and maintaining the engine room.Furthermore, in the case of vehicles with rotating (tilting) cabins, manual hydraulic jacks or special cylinders are usually used. It requires a rotation (tilt) method and the mechanism is complicated, which has many disadvantages in terms of labor and cost.

The purpose of this invention is to eliminate the above-mentioned problems.

(Means and effects for solving the problem) This invention was devised in view of the above points, and includes a rail-shaped member provided on the front surface of the cabin, a rotation fulcrum portion on the side surface, and A roller is detachably attached to a part of the mast, and the roller is rotatably engaged within the rail-shaped member, and when performing engine maintenance or parts replacement work, the roller is fixed to the mast. Later, by raising and lowering the mast, the cabin can be rotated and tilted about the pivot point, thereby improving the work efficiency.

(Example) Next, an example of this invention will be described based on the drawings.

FIG. 1 is an overall view of a forklift truck equipped with a device according to an embodiment of this invention, in which the cabin is directly attached to the frame. , 4 is a rail-like member, 5 is an inner mast, 6 is an outer mast, and 10 is a frame. FIG. 2 shows details of the cabin 1. A rail-like member is provided on the front surface of the cabin 1, and a plurality of pivot points 2 for rotating (tilting) the cabin 1 are provided on the side surface at a plurality of locations as shown in FIG. A roller 3 shown in FIG. 3 is mounted on this rail-like member 4 so as to be movable along the rail-like member (see FIG. 1). When the roller 3 needs to rotate (tilt) the cabin, the bracket 7 of the roller 3 is fixed to the inner mast 5 with a bolt 8 or the like. 5' indicates the left inner mast (see Figures 1 and 3).

Further, as shown in FIG.
Since it is rotatably attached to the fulcrum, the cabin can rotate (tilt) around this fulcrum (Fig. 5).

Note that the cabin and frame are usually fixed with stoppers or the like.

When rotating the cabin during maintenance and inspection, the roller 3 is moved to the inner mast 5 as described above.
When the inner mast 5 is raised,
As shown in FIG. 6, the roller 3 rises together with the inner mast 5 and moves within the groove of the rail-like member 4, so the cabin 1 rotates around its fulcrum 2 as shown by the arrow, and points at two points. The result will be as shown by the chain line.

Note that when rotating the above-mentioned cabin, it is desirable that the mast be perpendicular to the ground.

The cabin is then returned to its original position by lowering the inner mast in the opposite direction.

In the case of a forklift, the lowering of the fork and mast relies on its own weight, so if the cabin is heavy, it may be difficult for the cabin to return to its original position.

As described above, in the embodiment of this invention, the cabin can be easily rotated and tilted by utilizing the rise of the inner mast, thereby improving maintenance efficiency.

(Effect of the invention) This invention is constructed as detailed above, so
When servicing the engine or replacing parts, the cabin can be easily tilted and rotated around the rotational fulcrum by raising and lowering the mast, allowing the above-mentioned work to be carried out without any hindrance.
The extremely simple structure allows for easy inspection and maintenance inside the engine room, significantly improving maintenance efficiency.
