Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an escalator handrail repair tool suitable for repairing an escalator handrail.

[0002]

2. Description of the Related Art The handrail of an escalator is constantly rotating along a handrail guide. Therefore, if the escalator is used for a long period of time, the canvas portion in contact with the handrail guide may be worn, and the canvas may become loose. Therefore, we regularly repair the broken or torn parts of the canvas.

In the conventional repair method, the handrail is removed from the handrail guide, and the ear portion where the handrail is broken is extended while being pulled with both hands.
Other workers have been performing repair work using a cutter or the like to cut the torn canvas and replace it with a new canvas.

[0004] Techniques related to handrails include, for example, Japanese Utility Model Application Laid-Open No. Sho 61-105130 and Japanese Patent Application Laid-Open No. Sho 62-196297.

[0005]

By the way, in the prior art, the ears of the handrail are widened by hand, but the repair work is performed in the vicinity of the hand of this worker, because another worker uses the cutter. , Very dangerous. In addition, there is a problem that an extra worker is required for the repair work, and thus the work cost is high.

SUMMARY OF THE INVENTION It is an object of the present invention to provide an escalator handrail repair tool which can safely and inexpensively repair an escalator handrail in view of the above drawbacks.

[0007]

A first object of the present invention is to provide a fixing hook for fixing an ear at one end of a handrail of an escalator from the inside, and a movable hook for holding the inside of an ear at the other end of the handrail. A rod mounted in a direction in which the hook and the movable hook are pulled, a lever pivoted about a fulcrum, and a rod rotatably mounted on one end of the rod, and a pawl at a lower portion of the lever; Is achieved by providing a ratchet for fixing the

The second object is achieved by connecting a push button provided at the upper end of the rod to the push button and the claw body with a piano wire.

A third object is achieved by the rod comprising a stud and a nut, and adjusting the length of the rod by screwing the nut.

Since the repair tool of the present invention has the above configuration, the ear portion of the handrail to be repaired using the repair tool can be easily expanded and fixed, so that the repair work can be performed safely. Can be.

Further, since the work can be performed by one person, the work cost can be reduced.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS.

FIG. 1 is an overall configuration diagram of a repair tool for a handrail of an escalator according to the present invention. The repair tool includes a fixing hook 1 for fixing the ear at one end of the ear of the escalator, a movable hook 2 for gripping and pulling the ear at the other end,
A rod 3 for pulling the movable hook 2; a lever 4 for rotating the rod 3 about a fulcrum 46;
And a body 6 composed of a ratchet 5 for holding
Are fixed so as to have an integral structure.

FIG. 2 shows a detailed view of a main part of the rod 3. The rod is composed of a stud 31 and a nut 32.
When the nut 32 is screwed, the movable hook 2 moves, and the length of the rod 3 can be adjusted.

The lower end of the lever 4 is provided with a pawl 41 which engages with the ratchet 5, and when the pawl 41 is engaged with the ratchet, the lever 4 is configured to maintain that state.

FIG. 3 shows the internal structure of the handle above the lever 4. The push button 43 is connected to the claw body 41 via a piano wire 44 and is constantly pressed by a spring body 45.

FIG. 4 is a view in which the movable hook 2 is attached to the ear portion 81 of the handrail 8, and FIG.

Next, the operation of this embodiment will be described.

First, as shown in FIG. 4, the ear 82 of the handrail 8 is fixed to the inner surface of the fixing hook 2. Next, the nut 32 is screwed in, the rod 3 is adjusted, and the ear 81 is held by the movable hook 2. Then, as shown in FIG. 5, by holding the handle 42 and raising the handle 42 upward,
The handrail 8 extends to a predetermined interval and the claw body 4
1 bites into the ratchet 5 and the lever 4 keeps its state. Then, the operator repairs the damaged part of the handrail 8.

When the worker presses the push button 43 when the repair of the handrail 8 is completed, the claw body 41 comes off the ratchet 5, so that the lever 4 is lowered to the state shown in FIG. The rail 8 is removed from the fixing hook 1 and the movable hook 2 to complete the operation.

As described above, the ears 81 of the handrail 8
Since 82 can be easily expanded, the work can be performed safely.

[0022]

As described above, according to the present invention, the ear portion near the repair of the handrail can be easily expanded and held by using the repair tool, so that the repair of the handrail can be performed safely. In addition, since the repair work can be performed by one person, the operation cost can be reduced.
