Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rope flaw detector holding device for holding a rope flaw detector near a rope for detecting damage to the rope.

[0002]

2. Description of the Related Art In a conventional rope flaw detector, for example,
Working with the handle provided on the rope flaw detector, a detector for detecting the magnetic flux leaking from the surface of the rope due to damage such as cutting of the rope strand while passing the magnetic flux through the predetermined part of the moving rope A person grasps and approaches or comes into contact with the surface of the rope.

[0003]

SUMMARY OF THE INVENTION As in the above conventional example,
The following problems have been encountered in the rope flaw detector in which the detection unit is brought close to or in contact with the surface of the rope that is moved by the operator holding the handle.

(1) If the detector is brought close to or in contact with the surface of the rope with the handle of the rope flaw detector held by the operator, the worker's hand will tremble. Since the detection unit moves away from or approaches the surface of the rope, erroneous flaw detection occurs.

[0005] (2) If a wire protrudes from the surface of the rope, the wire is caught by the rope flaw detector,
There is a possibility that the rope flaw detector moves together with the rope, and the operator's hand is caught in the sheave of the hoist.

An object of the present invention is to provide a rope flaw detector holding device which can solve the above problems with a simple structure.

[0007]

SUMMARY OF THE INVENTION The object of the present invention is to provide a holding device for a rope flaw detector for detecting damage to a rope by bringing the rope close to or in contact with the surface of the rope wound around the hoist. An attachment base member detachably attached to a structure around the periphery, and one end is provided on the attachment base member, and the other end comprises an attachment angle adjustment member to which the rope flaw detection device is detachably attached,
This is achieved by making the mounting base member a suction cup structure.

According to this configuration, even if the operator does not hold the rope flaw detector in his hand, the rope flaw detector can be attached to a structure around the hoisting machine in a state of approaching or abutting on the surface of the rope. , And can be fixed by a mounting base member having a suction cup structure. Therefore, the detecting part of the rope flaw detector does not move away from or approach the surface of the rope due to the trembling of the operator's hand. The rope flaw detector can be prevented from being caught by the flaw detector and moving together with the rope, thereby preventing the occurrence of an accident in which the operator's hand is caught in the sheave of the hoist.

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

In FIG. 1, an elevator hoisting machine 1 comprises:
It is fixed to a mounting table 2 made of steel or the like on a floor surface of a machine room or the like. The sheave 3 of the hoisting machine 1 has a plurality of ropes 4
Is wound. The rope 4 has one end connected to a car (not shown) and the other end connected to a counterweight (not shown). The rope flaw detector 5 is fixed to the mounting table 2 by the holding device 6.

The holding device 6 is a structure around the hoisting machine 1, for example, a mounting base member 7 detachably mounted on the mounting table 2, one end of which is provided on the mounting base member 7, and other components. The end comprises a mounting angle adjusting member 8 to which the rope flaw detector 5 is detachably mounted. The rope flaw detector 5 includes a main body case 5A, a handle 5D provided on an upper surface of the main body case 5A, a detection unit 5B provided on a lower surface of the main body case 5A, and a hanging hook 5C provided on a side surface of the main body case 5A. ing. The detecting unit 5B includes the rope 4
And has a function of detecting a magnetic flux leaking from the surface of the rope 4 due to damage such as cutting of a wire forming the rope 4. Mounting base member 7
Comprises a suction cup 7A and a mounting angle adjustment member support 7B integrally provided at the center of the upper surface of the suction cup 7A. The mounting angle adjusting member 8 has a function of finely adjusting the mounting position of the rope flaw detector 5 with respect to the mounting base member 7 mounted on the mounting table 2.

When the surface of the mounting table 2 is not flat,
After the flat plate is fixed to the mounting table 2, the mounting base member 7 may be adsorbed to the flat plate. Further, by attaching a hanging string (not shown) attached to the ceiling to the hanging hook 5C of the main body case 5A, the rope flaw detector 5 is brought into a suspended state, and then the mounting base member 7 is attracted to the mounting table 2. It may be.

The flaw detection operation of the rope 4 using the holding device 6 having the above configuration may be performed in the following procedure.

(1) Main body case 5A of rope flaw detector 5
The holding device 6 is attached to the rope flaw detector 5 by screwing the mounting angle adjusting member 8 of the holding device 6 to the holding member 6.

(2) The mounting base member 7 of the holding device 6 is
The rope flaw detection device 5 and the holding device 6 are attached to the mounting table 2 by adsorbing the mounting table 2 so that the detection unit 5B of the rope flaw detection device 5 reaches the sheave 3 of the hoisting machine 1.

(3) By operating the mounting angle adjusting member 8, the detecting portion 5B provided on the lower surface of the main body case 5A is moved
Bring it close to or in contact with the surface of the rope 4.

(4) The rope 4 is moved in a state in which the detection unit 5B is close to or in contact with the surface of the rope 4 to search for damage to the rope 4.

According to the holding device 6 having the above configuration, even if the operator does not grip the rope flaw detection device 5, the main body case 5 can be used.
Since the detection unit 5B of A can be brought close to or in contact with the surface of the rope 4, the operator's hands do not get tired, and the workability is excellent.

Further, since the rope flaw detection device 5 is not gripped by the operator, the detection part 5B does not move away from or approach the surface of the rope 4 due to the shaking of the operator's hand, thereby preventing erroneous flaw detection. At the same time, the wire protruding from the surface of the rope 4 is caught by the rope flaw detection device 5, and the rope flaw detection device 5 moves together with the rope 4, and the worker's work is put on the sheave 3 of the hoisting machine 1. It is possible to prevent the occurrence of an accident in which a hand is pinched.

If the rope flaw detector 5 shakes greatly during the flaw detection work of the rope 4, the main body case 5A
It is preferable that the operator grips the handle 5 </ b> D and presses the rope flaw detector 5 toward the rope 4.

[0021]

As described above, according to the present invention, the detection portion of the rope flaw detector does not move away from or approach the surface of the rope due to the shaking of the operator's hand, thereby preventing erroneous flaw detection. As well as the wires protruding from the surface of the rope are caught by the rope flaw detector,
It is possible to obtain a rope flaw detector holding device that can prevent the rope flaw detector from moving together with the rope, thereby preventing the occurrence of an accident in which an operator's hand is pinched by a sheave of a hoist. Was.
