易である等種々の効果がある。 [Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a rail gap determination device that determines the end cross-sectional interval (hereinafter referred to as clearance) of each rail at a rail joint. [Prior art] The end cross-sectional spacing (gap) of each rail at rail joints in railways, etc. is the standard dimension (6 to 8 m/m).
Bolt holes are drilled and tightened with joint bolts to maintain the same temperature.However, during low temperatures in winter, when the rail contracts and the clearance widens, exceeding the limit, the joint bolts are tightened at the joints. There was a risk that the tubes could be bent or damaged, and the insulation tubes could be damaged at insulated locations, disrupting train operation. Therefore, conventionally, for example, as in Japanese Utility Model Publication No. 55-50561, a curved plate is provided on one of the rails at the joint part of the rails, and a core that is slidable in the front and rear direction is provided at a position corresponding to the curved plate. A displacement meter for detecting the movement of the core is provided on the other rail, and the tip of the core is brought into contact with the curved plate, and the movement of the curved plate is used to operate the displacement meter, thereby measuring the length, width, and length of the track girder. There is a device that detects relative displacement in three directions, but this device measures the deviation in the end cross-sectional spacing of each rail at the rail joint using an electrical resistance displacement meter, and then sends this information to the central control room. Since this is a device that uses so-called electrical detection means, it notifies the operator with an alarm buzzer, lamp, etc. if the deviation exceeds the standard value, so the measured values from the displacement meter are sent to the central control room. Not only does it require electrical circuits (devices), alarm buzzers, lamps, operators, and other equipment, equipment, devices, and work personnel, which not only has the drawback of being quite expensive.
In particular, when installing the device, it requires skill and effort to install the curved plate in the correct posture and to align the center of the core horizontally with the center of the curved plate, which has the disadvantage of lacking workability, and also prevents maintenance. However, it has various problems such as being troublesome. [Purpose] The present invention is designed to easily check the limits of clearance defects due to rail shrinkage and other causes (bending of joint bolts, insulating tubes, etc., points where damage occurs) through visual inspection using mechanical detection means, and thereby By making early corrections, bending and damage to joint bolts, insulating tubes, etc. can be prevented. Mechanical detection has a simple structure that prevents failures, is inexpensive, and is easy to install and maintain. The object of the present invention is to provide a rail clearance determination device comprising means. [Structure] In order to achieve the above object, the present invention is a rail clearance determiner that determines the end cross-sectional interval of each rail at a rail joint, and has a sensing arm storage that can be attached to the outer surface of one rail head. inside the case,
The base of the sensing arm with a clearance distance scale is rotatably mounted on a pivot, and the sensing rod mounting body is formed so as to be attachable to the outer surface of the other rail head facing the sensing arm storage case, and penetrates laterally. A sensing rod of a required length is inserted into the formed through hole so that its protruding length can be freely adjusted, and the tip of the front-loaded sensing rod is passed through the sensing rod guide hole formed on one side wall of the sensing arm storage case to store the sensing arm. It is characterized in that it is inserted into a case so that the sensing arm is supported by the sensing rod, and the sensing rod mounting body is provided with a tightening screw for tightening the sensing rod. This will be explained in detail below based on examples. Reference numeral 1 denotes a sensing arm storage case, and inside the sensing arm storage case 1 , a sensing arm 3 having a clearance distance scale 2 is rotatably mounted at its base 4 by a pivot shaft 5. Reference numeral 6 denotes a sensing rod attachment body, and a through hole 7 is formed in the sensing rod attachment body 6 in the horizontal direction, and a sensing rod 8 of a required length protrudes from the through hole 7, the length of which can be freely adjusted. is inserted into. Numeral 9 is a tightening screw for tightening the sensing rod. Reference numeral 10 denotes a sensing rod guide hole formed on one side wall surface of the sensing arm storage case 1 , through which the tip end side of the sensing rod 8 passes. 11 and 11 are rails, 12 and 12 are rail joint plates, 13 and 13 are insulating plates, 14 is a joint bolt, and 15 is a clearance. Note that an insulating plate may be interposed in the clearance 15. The sensing arm storage case 1 and the sensing rod mounting body 6 are formed to be attached to the outer surface of the head of each rail 11, 11 using a well-known instant adhesive, and all parts are made of plastic with good insulation. It is also possible to do so. When using the present invention, first the rails 11, 1
1, the failure limit of the clearance 15 (the interval at which the joint bolt 14 or the insulating tube etc. is bent or damaged) is determined, and the sensing arm storage case 1 and the sensing rod mounting body 6 are installed outside the heads of the rails 11 and 11, respectively. The sensing rod 8 of the sensing rod mounting body 6 is made to protrude into the sensing arm storage case 1 through the sensing rod guide hole 10 of the sensing arm storage case 1 , and the sensing arm 3 is mounted on the side at a required distance. The sensor arm 3 is supported and the proximal end of the sensing rod 8 is tightened to the sensing rod mounting body 6 using the tightening screw 9. This completes the installation.
However, in this state, if the rails 11, 11 contract due to cold or other causes, the gap 15 between the rails 11, 11 opens, so the lap state (overlapping state) between the sensing arm 3 and the sensing rod 8 is reduced. When the clearance 15 reaches just before a predetermined failure limit, the sensing arm 3 separates from the sensing rod 8, loses its supporting force, and falls and rotates downward about the pivot 5 due to its own weight. Therefore, by visually observing the condition, the inspector can easily determine that the rail clearance has reached the limit of failure, and correct the rail clearance before the joint bolt or insulation tube bends or breaks. It is something that can be done. [Effect] According to the present invention, there is provided a rail clearance determiner for determining the end cross-sectional interval of each rail at a rail joint, and the sensing arm storage case is provided in a sensing arm storage case that is formed to be attachable to the outer surface of one rail head. The base of the sensing arm with a clearance distance scale is rotatably mounted on a pivot, and the sensing rod mounting body is formed so as to be attachable to the outer surface of the other rail head facing the sensing arm storage case, and penetrates laterally. A sensing rod of a required length is inserted into the formed through hole so that its protruding length can be freely adjusted, and the tip of the sensing rod is passed through the sensing rod guide hole formed on one side wall of the sensing arm storage case. The sensing arm is inserted into the rail and is formed so that the sensing arm is supported by the sensing rod, and the sensing rod mounting body is provided with a tightening screw for tightening the sensing rod. An inspector can easily check whether the rail clearance is correct or defective by visually inspecting the rotating state of the sensing arm, and as a result, the rail clearance can be inspected easily and reliably. At the same time, it is possible to check in advance the fault limit of the rail clearance, so the clearance can be corrected at an early stage to prevent bending or damage of joint bolts, insulation tubes, etc., and it also has a simple mechanical detection system. This method is not only less prone to failure than conventional electrical detection means, but also very low in cost. In particular, when installing the device, it is necessary to separate the sensing arm storage case and the sensing rod mounting body, respectively. The sensing rod of the sensing rod mounting body is attached to the outer surface of the head of the rail at a required distance, and the sensing rod of the sensing rod mounting body is made to protrude into the sensing arm storage case through the sensing guide hole of the sensing arm storage case. It is only necessary to set the distance just before the failure limit using the clearance distance scale, support the sensing arm, and tighten the proximal end of the sensing rod to the sensing rod mounting body using the tightening screw, which requires skill. It has various effects, such as being able to be easily installed without any trouble or effort, having very good workability, and being easy to maintain after installation.
