Abstract

PROBLEM TO BE SOLVED: To make a ring easily visible and to easily find the abnormality of a bolt by applying a red color or a yellow color which is a conspicuous color to the ring integral with a tube section covered on the apex of the bolt. SOLUTION: A ring 3 integral with a tube section 2 made of a soft synthetic resin is coupled with the apex of a bolt 1, and the ring 3 is colored in conspicuous red or yellow. The inside of the tube section 2 is coated with a strong adhesive, and the tube section 2 is covered on the apex of the bolt 1 so that the whole ring 3 is visible from the advancing direction of a train. The whole ring 3 is directed in the advancing direction of a worker, and a visual inspection can be fully made. When an abnormality occurs on the bolt nut, it can be easily found.

The actual situation of the inspection and maintenance work of the bolts of JR companies is as follows. (A) In each JR company, the conventional inspection of bolts is performed by visual inspection while a maintenance worker walks. (B) Inspection of bolts is performed once every one to two months. (C) The working hours are extremely short due to work from midnight to dawn after the last train. (D) Track maintenance work is carried out every day, but it is carried out in sections for the convenience of personnel. (E) It was impossible to keep an eye on hundreds or thousands of kilometers of railway tracks. (F) It is impossible to secure a huge amount of security by installing sensors on all Shinkansen lines. This method is also worthless if it can pass through the sensor. In fact, the sensor was breached and a crime was committed. (G) At present, JR companies conclude that the policy is to increase the number of workers and strengthen patrols, but it is impossible to permanently implement this human naval tactic. Therefore, the fact is that JR companies have no effective means of dealing with this vandalism. The present invention has been made to eliminate these disadvantages with simple equipment and methods.

According to the present invention, a ring (3) is provided at an end of a body of a cylindrical portion (2) so as to be integrated.
The tubular part is naturally hollow and covers the top of the bolt (1). By this covering, the act of removing the bolt can be prevented, prevented, and suppressed, and when an abnormality occurs in the bolt (1), it can be easily found. By practicing the present invention, only 10 people are required,
A reliable inspection of all bolts on a 1,000 km long railway is possible, and this takes only a few hours. Therefore, a thorough daily inspection can be performed. This mechanism will be described in detail below. (B) It is impossible to prevent the invasion of vandals. (B) It is also important to take measures to remove or abandon the bolts even if they are intruded. (C) It is also important to be able to find bolt changes with minimum cost and minimum personnel. (D) It is also important to minimize the inspection performance of bolts and maximize the scope of inspection actions. Description will be made from the above viewpoint. In the present invention, the ring (3) integrated with the cylinder (2) is made of synthetic resin, but the cylinder (2) fitted on the top of the bolt (1) is made of soft synthetic resin. . This is for facilitating the mounting work on the bolt. The circular ring (3) has a diameter of 3.5 cm, the thickness of the ring is 2 cm, and the thickness of the cylindrical portion is 2 mm, but this value can be easily changed according to the situation at the site. Apply a strong adhesive to the inside of this cylindrical part (2),
Cover the top of the bolt (1). At this time, the covering is performed so that the entire ring (3) can be seen when the train is viewed from the traveling direction as shown in FIG. The present invention is a bolt-and-nut with a ring configured as described above.

The ring (3), which is integral with the cylindrical portion (2), which covers the top of the bolt (1), has a distinctive color of red or yellow, and may be coated with luminous paint. This is because it is easily visible. Since the center of the ring (3) is naturally a space, the wind pressure of the train can be reduced, so that the train is not bent or deformed by the wind pressure. The integrated cylindrical portion (2) and ring (3) are made of synthetic resin and are not corroded, so they are semi-permanent.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A tubular part (2) integrated with a ring (3) is
The top of the bolt (1) fixing the rail (4) is covered. Since it is covered with a strong adhesive, it does not peel off due to the wind pressure of the train. It is desirable to attach to all bolts, but they may be equally spaced depending on the situation at the site. When an intruder breaks down, it is performed with a large box-type wrench or a horizontal variable wrench.
The wrench cannot be fitted without first cutting or tearing off the top ring (3). Therefore, since the ring is not upright, the anomaly of the bolt can be easily found. Using a horizontal wrench is exactly the same. Therefore, there is a great psychological upset and repression effect of the vandal.

[Effects of the Invention] At present, JR companies are increasing the number of work personnel and strengthening patrols for bolt inspection. However, if the present invention is implemented, the total length is 1 with only 10 personnel and few equipment.
All bolts on a 000 km rail can be completely inspected in 2-3 hours. To explain this in detail, the ring (3) of the present invention stands upright on the top of the bolt (1) fixing the rail (4), so that it can be easily seen. In other words, a bolt whose ring is not upright is a bolt that has undergone an abnormal change. At present, walking inspections are limited to 1 km per hour per person. For example, if a 1,000 km long rail is divided into 5 sections,
One section is 200 km. The ring is prominent even at night, so the work vehicle is mounted on the rails, regardless of walking, and both the driver and the inspector ride on the rails, driving at 80 km / h with bright lights on the rails. Since the entire ring is oriented in the traveling direction of the work vehicle, visual inspection is sufficiently possible. As a result of the experiment, it is possible even at 100 km / h. Even if you make a round trip of 200km per section, the required time is 4
Since it is about 5 hours, it can be sufficiently executed within the time from the last train until dawn. Therefore, inspection of all bolts on a 1,000 km long track can be carried out 365 days a year, with 10 personnel and 5 working vehicles. Further, if the work vehicle is equipped with a television camera or the like and is driven unmanned, labor saving is completed. The following aspects are possible from the present invention. (A) Instead of the ring (3), a light source such as a solar cell lamp or a reflector may be provided. (B) It is also possible to cover bolts and nuts on high-voltage towers and buildings that were targeted for destruction. As described above, since the present invention can be mass-produced, it is inexpensive and semi-permanent, and can greatly reduce the psychological upset and repression of the vandal, and most of all, contribute to rationalization and labor saving. However, reliable inspection capability and speeding up are revolutionary.
