Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaning line for various fiber ropes.

[0002]

2. Description of the Related Art Conventionally, dirt such as mud and dust adhered to a fiber rope during use has been removed, and the diameter of the rope has been measured at the same time (as a guideline for the degree of rope fatigue) to inspect damaged areas. Aftercare, such as ri, was individually and independently performed as a single aftercare such as cleaning only or inspection of a damaged part.

[0003]

By the way, in order to prepare for the next use, the fiber rope after use removes dirt such as mud and dust adhered at the time of use, and at the same time, measures the diameter of the rope and removes damage points. Ideally, it should be stored after undergoing inspections and other aftercare. Because the lack of rope fatigue degree inspection and the lack of inspection of damaged parts immediately cause an accident, and the lack of cleaning leads to a decrease in commercial value at the time of reuse. Because it is not invited. Unfortunately, so far, however, each of these tasks has tended to be satisfactory with a single aftercare, such as only cleaning or inspection of the damaged area, as described above. Specifically, the cleaning,
The actual situation is that each work such as measuring the diameter of the rope and inspecting the damaged part is done by hand, independently, or by a single-function device without any relation to each other. Therefore, when the systematic work is intended, there is a problem that the workability is very low due to a lot of loss of mutual carrying work and the like.

Therefore, the present invention has been developed in view of such problems, and a fiber which can improve workability by a rational line structure and can sufficiently secure safety during reuse. The purpose is to provide a rope cleaning line.

[0005]

In order to achieve the above-mentioned object, the present invention provides the above-mentioned method in the middle of a line from a supply roll of a rope provided at a starting point of a moving line of a fiber rope to a winding roll of an end point thereof. Rope cleaning device equipped with a group of rotating brushes for brushing the entire circumference of the rope that moves the line in sequence from the supply roll side to the take-up roll, and a cleaning liquid supply means, a cleaning liquid that adheres by blowing high-pressure air We adopted a configuration in which a draining device that blows away water, a drying device, a rope diameter measuring device, and a length measuring device are arranged in a line.

[0006]

Operation: To wash the rope in the fiber rope washing line configured as described above, set the supply roll on which the used rope is wound in advance at the beginning of the line, and then pull the rope at that end. When the rope is supplied to the line, one end of the rope is pulled out from the supply roll and is sequentially paid out toward the winding roll at the end point of the line.First, the rope is completely removed by the brush that rotates while being supplied with the cleaning agent and cleaning water in the cleaning device. By brushing the entire surface thoroughly, dirt, dust, dust, etc. attached can be washed off cleanly. Next, when the cleaning is completed, the cleaning agent is drawn into the water draining device, where high-pressure air is blown from the peripheral surface to blow off the cleaning agent or cleaning water that adheres. Subsequently, it is drawn into the drying device, and hot air is blown from all the circumferences to evaporate and dry the water adhering to the surface as well as the water that has penetrated into the inside all at once. Then, the size of the rope diameter is measured to check whether there is an abnormality in the rope diameter or whether there is a damaged portion, the length of the rope is measured, and finally the winding roll is sequentially wound. As a result, unlike the conventional method, all the working steps of washing, draining, drying, measuring the rope diameter, and measuring the length are all completed in a series of rope transfer lines.
