DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wire rope guide device for hanging a plurality of wire ropes such as a bridle and a hanger in a climbing crane.

[0002]

2. Description of the Related Art As a rope guide device having a guide plate
The one described in Japanese Utility Model Publication No. 60-64994 is known.
Have been. This equipment is suitable for cargo handling machines such as cranes.
Applied to the hook block used,
On the outer periphery of the pulleys that are pivotally supported between the pulley frames,
A semi-circular retaining bracket made of plate material is provided.
Then, to insert two pipes into this stopper metal fitting
It is configured by And this stopper metal
Pulley and retaining bracket and pipe by means of tool and pipe
The gap between them should be small and the wire rope should come off the pulley.
Has been prevented.

[0003]

[Problems to be Solved by the Invention] Rope replacement and rope
When changing the number of wires, pull the wire rope from the pulley described above.
It is necessary to remove it and put it in the pulley. The above-mentioned
The loop guide device prevents the wire rope from coming off the pulley.
Rope stoppers and pipes and pulleys
The gap must be small, and in general, the gap
To about 0.1 to 0.15 times the diameter of the wire rope
There is a need to. Therefore, when pulling in the wire rope
Then, remove the rope stopper metal fitting and pipe from the pulley frame.
And slide it downward to increase the distance between the pulley and the rope stopper.
I have to ask. Therefore, no rope replacement work
There is a problem that it takes time to reduce workability.
I will.

[0004]

According to the present invention, a plurality of sheaves are rotatably supported via a shaft between two plate-like portions forming a support frame, and a wire rope is hung on each sheave. In the wire rope guide device, a plurality of detent pins are attached at intervals on the same arc of the plate-like portion along the outer peripheral edge of the coaxial sheave, and between the detent pins that are adjacent to each other. It is characterized in that a guide plate having a circular cross section or a plurality of polygonal sides is arranged.

[0005]

Operation: When the wire rope is retracted, it is guided by the guide plate, and the detachment of the wire rope is prevented by the disengagement prevention pin.

[0006]

1 to 3 show an embodiment of the present invention.
This will be described below.

Between the two plate-like parts 2 forming the support frame 1
A plurality of, for example, three stoppers are provided at intervals on the same arc of the plate-like portion 2 along the outer peripheral edge of the sheave 3 rotatably attached to the shaft 5 attached to the shaft 5 via a ball bearing 4. A pin 9 is attached. One plate-shaped part 2
A rectangular support plate 10 is fixed to the inner wall surface of the plate with bolts 11, and two guide plates 12 each having a circular cross section are fixed to the support plate 10 by welding. The guide plates 12 are arranged between the adjacent detent pins 9 and surround the outer periphery of the sheave 3. The guide plate 12 may be directly fixed to the plate-shaped portion 2.

A guide plate 12 guides the wire rope when it is retracted, and the detachment of the wire rope is prevented by a disengagement prevention pin 9. Guide plate 12 is wire rope
Does not serve as the outskirts prevention, Ru can be somewhat larger gap between the outer periphery of the guide plate 12 and the sheave 3. Should
Securely prevent the wire rope from coming off with the retaining pin 9.
When the wire rope is retracted, the guide plate 12 and
Since it is not necessary to remove the retaining pin 9, the work is easy
Easy to do.

In FIG. 4, a guide plate 13 having a plurality of polygonal sides in cross section is formed between adjacent detent pins 9.
Another embodiment of the present invention in which is arranged is shown.

[0010]

According to the present invention described above, it is possible to easily provide a wire rope guide device which facilitates the retraction of the wire rope and can reliably prevent the wire rope from coming off.
