Description

  The present invention relates to a building limit measuring instrument for placing on a rail surface of a railway track to indicate a building limit.

  In general, facilities around railway tracks must be installed outside the building limits, which allow for space on the top and bottom and sides of the vehicle so that the vehicle can travel safely on the track. At the time of installation and after installation, it is confirmed that the equipment does not penetrate the building limits. However, the presence or absence of peripheral equipment entering the building limit is often confirmed by showing the building limit by laying tape or thread on the basis of the rail, and the confirmation work takes time and effort.

On the other hand, for example, Patent Document 1 discloses a building limit inspection apparatus arranged on a rail to indicate a building limit. FIG. 3 shows a building limit inspection apparatus disclosed in Patent Document 1. This building limit inspection apparatus includes an insulating tower 101 disposed on a rail, a lower side lower limit gauge 103 supported by the insulating tower 101 via a frame 102 and showing a part of the building limit, and an upper side lower limit gauge 104. And an upper limit gauge plate 105, which checks the presence or absence of an obstacle while traveling on the rail.

Can be easily carried around. In addition, since the housing groove is formed in the measuring instrument main body, the side member can be housed in the housing groove so that it can be folded into a single rod shape.

  Here, the building limit is set so as to surround the vehicle vertically and horizontally, but peripheral equipment is often installed in a range where the height from the rail surface is 1900 mm or less, for example, and many of the places to be measured are Only the lower part of the member indicating the construction limit is required. Therefore, both the assembled state and the folded state are left out of the construction limit by leaving the frequently used members indicating the lower part and the side part (particularly the lower part) and omitting the less frequently used members indicating the upper part. It is possible to reduce the size and weight of the building limit measuring instrument.

  In addition, the side members are configured by hinge-connecting the end portions of the first side member and the second side member and also connecting the end portions of the first side member to the measuring instrument main body. Further, a rod-shaped first diagonal member having one end hinged to the first side member and the other end detachably joined to the measuring instrument main body so as to restrict the swing of the first side member in the assembled state; A rod-shaped second diagonal member having one end hinged to the second side member and the other end detachably joined to the measuring instrument main body is provided so as to restrict the swing of the second side member in the assembled state. Furthermore, the accommodation groove is set to a groove width that can be accommodated by overlapping the second side member hinged to the first side member and the first diagonal member.

  According to this configuration, the portion constituted by two straight lines in the side construction limit is indicated by the first side member and the second side member, and the swing is expressed by the first diagonal member and the second side member. The assembled state of the building limit measuring instrument can be maintained by regulating with diagonal materials. In addition, one end of the first diagonal member and the second diagonal member are hinge-coupled to the first side member and the second side member, respectively, and the other end is detachably joined to the measuring instrument body. Can be freely assembled and folded. Furthermore, the second side member and the first diagonal member overlap each other by being hinged to the common member, i.e., the first side member. The building limit measuring instrument can be folded into a single bar.

  In addition, the measuring instrument body is provided with a positioning portion that engages with the rail to position the construction limit measuring instrument in the line width direction, and this positioning section is a circular cross section that protrudes from the lower surface of the measuring instrument body so as to make point contact with the rail. This is the protrusion. Then, when the measuring instrument main body is placed on the rail surface and positioned in the line width direction, the protrusion as the positioning portion is brought into point contact with the rail to be engaged, so that the measuring instrument main body is accurate with respect to the rail. Even if a slight inclination is produced without being orthogonal to, it is possible to show a substantially accurate construction limit.

  As described above, according to the present invention, the measuring instrument main body and the side member are hinge-coupled so as to be assembled and folded, and the receiving groove for receiving the side member is formed in the measuring instrument main body. This shows the building limit by assembling the building limit measuring instrument and placing it on the rail surface of the railroad track, and folding the building limit measuring instrument into a single bar by storing the side member in the receiving groove.
