[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a traveling rail used for an automatic transfer device such as a hoist.

[0002]

2. Description of the Related Art FIGS. 5 to 7 are side views of a conventional hoist,
1 shows a rail 2 made of I-section steel, showing a front view and a plan view.
A traveling rail 5 made of a steel strip 4 welded to an engagement contact portion between the traveling wheel 3 and the traveling wheel 3 is a traveling motor for driving the traveling wheel 3. The traveling wheel 3 and the traveling motor 5 are mounted on a mounting member 6 (there is only half of the traveling wheel 3). Two mounting members 6 are rotatably connected to a bogie 7, and the bogie 7 is also connected. It is rotatably connected to the member 8. The traveling part 15 is formed by the traveling wheel 3, the traveling motor 5, the mounting member 6, the bogie 7, and the connecting member 8.
Reference numeral 9 denotes a hoisting portion connected to and supported by the connecting member 8, which includes a hoisting drum and a hoisting motor 11 for driving the hoisting drum and a hoisting brake 12 for braking. Reference numeral 13 denotes a sheave supported on a hoisting drum via a rope 14.

In the conventional hoist described above, when the traveling motor 5 is driven, the traveling wheels 3 rotate, the traveling wheels 3 travel on the strip 4 of the traveling rail 1, and the traveling section 15 moves along the traveling rail 1. To run. Therefore, the winding part 9 moves. When the hoist drum is driven to rotate by the hoist motor 11, the sheave 13 moves up and down via the rope 14,
The transported object connected to the sheave 13 can be suspended, and the transported object is transported by the movement of the winding section 9.

[0004]

In the above-mentioned conventional hoist, when the hoist is frequently used, the traveling rail 1 is not used.
The strip 4 was worn, and the entire traveling rail 1 had to be replaced, which required much labor and time. This was also the case when the running rail was formed of an I-beam or an H-beam alone.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and has as its object to provide a traveling rail for an automatic transfer device which can easily repair a worn traveling rail. And

[0006]

The traveling rail for an automatic transport device according to the present invention has an end integrally formed at the upper and lower ends of the center.
The rail made of H-beam and the center of the rail
A pair of bosses standing on both sides of the lower part and a rail
Is placed on the lower end of the
Equipped with a pair of square rails, the boss standing part at the center of the rail, each
Insert through the boss and through holes provided in each square rail
Bolts and nuts to fasten and fix each square rail to each boss
The traveling wheels run on each of the square rails.
Things.

[0007]

In this invention, the rail made of H-section steel
Together the pair of ball scan on both sides of the central subordinate unit is erected
At the bottom of the rail so that it contacts the tip of the boss.
A pair of square rails are placed, a boss standing part at the center of the rail,
Inserted into through holes provided in each boss and each square rail
Bolts and nuts secure each rail to the boss
The traveling wheel travels on each of the square rails .

[0008]

EXAMPLES Hereinafter, an embodiment of the invention in conjunction with the drawings. 2 to 4 show a front view, a side view and a plan view of a hoist according to this embodiment , and 16 is a running rail. As shown in FIG. 1, the traveling rail 16 is located above and below the center.
Rail 1 made of H-section steel with ends attached integrally to both ends
A square rail 18 is detachably attached to an engaging contact portion of the rail 7 with the traveling wheel 3, and specifically, bosses 19 are erected and fixed on both side surfaces at the lower part of the center of the rail 17, respectively . Abuts the tip of boss 19 on the lower end of rail 17
So that a pair of square rails 18 is placed and bolts 20 are
Through hole of rail 18, through hole of each boss 19, rail 17
Through the through hole provided in the boss standing portion at the center of the
Each corner by tightening the nut 20 with the nut 21.
The rail 18 is fastened and fixed to the boss 19, and each of the square rails 1
The traveling wheel 3 travels on 8. The configuration other than the running rail 16 is the same as the conventional one, and the operation is the same as the conventional one.

In this embodiment as well, each square rail 18 is worn due to the engagement contact with the traveling wheel 3. In this case, the nut 21 is removed and the bolt 20 is pulled out.
Each square rail 18 can be removed at a time,
Rails 18 can be easily attached, and each square rail 18 can be attached and detached.
Becomes easier.

[0010]

[Effect of the invention] As described above, according to the invention, the H-shaped steel
The square rail is detachably attached to the engagement contact portion of the rail with the traveling wheel, and when the square rail is worn by the engagement contact with the traveling wheel, it is not necessary to replace the entire traveling rail, and the square rail is not required. Only replacement is required, and repair becomes very easy. Moreover, the left and right square rails are
Since they are fastened together, their attachment / detachment work becomes easier.
You.
