DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for mounting a sliding member between an outer mast and an inner mast in a forklift.

[0002]

2. Description of the Related Art In a mast device of a forklift, a sliding member facilitates up and down operation of an inner mast, and when a load is applied, a front side is a roller and a sliding member on the opposite side receives the roller. The conventional sliding member a is provided with a pin portion p as shown in FIG. 5 and fitted and fixed in a hole d on the outer mast b side as shown in FIG. FIG. 7 shows the arrangement of the sliding member a, the outer mast b, the roller mounting pin e, and the inner mast c, and FIG. 8 shows a drill hole d provided in the outer mast b. 9 and 10
5A and 5B are a top view and a front view showing a mounting position of a sliding member a in the mast device. In the figure, f indicates a lift bracket.

[0003]

The sliding member receives a load in addition to the operation of moving the inner mast up and down, which causes a failure, abrasion, breakage, etc., and requires adjustment and replacement. Since the sliding member is surrounded by the outer mast and the inner mast, there is a problem that the sliding member cannot be replaced as it is.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and is provided on an outer mast.
The U-shaped groove for mounting the sliding member is formed as a groove opened upward, and the fixing member of the sliding member is eliminated, and the sliding member is fixed by bolts.

[0005]

According to the above construction, no special disassembly work is required at the time of adjusting or replacing the sliding member. The sliding member can be stored in a fixed position by being slid from above, and can be fixed from outside by bolts.

[0006]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is an exploded view showing a sliding member mounting groove shape and a sliding member provided on an outer mast, FIG. 2 is a three-side view of the sliding member, FIG. 3 is a perspective view showing a first embodiment, and FIG. Second
It is a perspective view which shows the Example of FIG.

As shown in FIGS. 1, 3 and 4, a U-shaped groove 2b is formed in the outer mast 2 for mounting the sliding member 1.
Or a side plate 6 provided in the U-shaped groove 2b.
Are attached, but each has a shape in which the upper end of the groove is opened.

Since the upper end of the groove is open, the shim 5 can be slid into the sliding member 1 from above the outer mast 2 and can be replaced without disassembling the inner mast 3 in particular. . The sliding member 1 fitted into the fixed position is fixed from the outside of the outer mast 2 through the screw hole 2a by the bolt 4 using the drill hole 1a.

[0009]

As described in detail above, the present invention makes it possible for one worker to easily adjust and replace the sliding member by changing the shape of the sliding member and the groove and the method of assembling. At the same time, dangerous disassembly work is eliminated, which helps to improve work efficiency and safety.
