Description

  The present invention relates to a connection structure for a train line gantry structure, and more particularly to a connection structure for a train line gantry structure in which end faces in the longitudinal direction of a plurality of train line gantry structures are brought into contact with each other.

  A rigid train line for supplying electric power to a vehicle is configured by holding a trolley line on which a vehicle current collector (pantograph) slides on a holding surface of a rigid train line mount. Such a rigid train line has a length of, for example, 10 m to 20 m, and is connected to a train line structure in the longitudinal direction, and is laid on the top of a subway or a tunnel, It is used by laying on rails.

  For example, as shown in FIG. 8, the train-line gantry constructing bodies 100 a and 100 b are connected to each other by joining the end surfaces 110 a and 110 b in the longitudinal direction to each other and welding the abutted end surfaces 110 a and 110 b. Generally, the end surfaces 110a and 110b of the train line gantry constructs 100a and 100b are formed perpendicular to the longitudinal direction of the train line gantry constructs 100a and 100b. When the end surfaces 110a and 110b of the train line frame structures 100a and 100b are connected by welding, heat generated during welding is concentrated at one place in the longitudinal direction. When heat generated during welding is concentrated at one place, high stress is generated, and the connecting portion of the train line gantry constructs 100a and 100b is deformed in the height direction of the train line gantry constructs 100a and 100b. Such a deformation causes irregularities to be formed on the holding surfaces 109a and 109b of the completed rigid train wire platform.

  The irregularities present on the holding surfaces 109a and 109b also cause irregularities on the trolley wire. If the trolley line has irregularities, the contact between the current collector of the traveling vehicle and the rigid train line becomes unstable, and power cannot be normally supplied. Moreover, the unevenness | corrugation which exists in a trolley wire will wear a trolley wire quickly, and it becomes necessary to replace | exchange trolley wires frequently. Therefore, the welding operation of the train line gantry constructs 100a and 100b is to form the holding surfaces 109a and 109b flat in the longitudinal direction without causing deformation in the connecting portions of the train line gantry constructs 100a and 100b. is necessary.

  A skilled worker anticipates the deformation of the train line gantry constructs 100a and 100b and performs welding after adjusting the positions of the train line gantry constructs 100a and 100b in advance. The adjustment of the positions of the train line gantry constructs 100a and 100b allows the holding surfaces 109a and 109b to be formed flat in the longitudinal direction even if the connecting portions of the train line gantry constructs 100a and 100b are deformed. However, raising skilled workers is time consuming and expensive. On the other hand, if a worker with low skill level performs the same work as a skilled worker, the welding work takes time, and the work efficiency is poor.

  The deformation that occurs when connecting the train line gantry structures 100a and 100b is caused by heat generated by welding. In order to solve such a problem, for example, Patent Document 1 proposes a connection structure for a gantry structure for a train line that connects rigid train lines with bolts.

JP-A-7-309161

  Since the connection structure of the train line gantry structure proposed in Patent Document 1 does not perform welding, there is no problem that heat due to welding deforms the train line gantry structure 100a, 100b. Therefore, the connection structure of the train line gantry structure proposed in Patent Document 1 can easily connect the train line gantry structure even if it is not a skilled worker.

  However, in the connection structure of the train line gantry structure proposed in Patent Document 1, when the processing accuracy of the end surface of the train line gantry structure is low, the end surfaces of the train line gantry structures that are abutted with each other A minute gap is formed. In addition, even if such a connection structure is connected with the end faces of the gantry structure for a train line abutting each other without a gap, when the bolt is loosened, a gap is formed between the end faces of the connected rigid train lines. Misalignment may occur. For this reason, the problem of providing a rigid railcar pedestal having no unevenness on the holding surface has not been solved.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a train in which a holding surface for holding a trolley wire can be formed flat without causing deformation in a connecting portion of a gantry structure for a train line. An object of the present invention is to provide a connection structure for a wire frame structure.

  In order to solve the above-mentioned problems, the connection structure of the gantry structure for a train line according to the present invention is a connection structure of a gantry structure for a train line that connects the end faces in the longitudinal direction of the plurality of trolley structure structures for a train line. The end surface of one of the connected trolley wire structures is processed so that a part or the whole of the position in the longitudinal direction in the end surface varies depending on the position in the height direction orthogonal to the longitudinal direction. The end surface of the other trolley wire mount structure to be connected differs depending on the position in the height direction in which a part or the whole of the position in the longitudinal direction in the end surface is orthogonal to the longitudinal direction. And it is a processing end surface processed so as to correspond to the processing end surface of the above-mentioned one trolley wire frame structure, and the processing end surfaces which face each other are welded.

  According to this invention, a part or the whole of the position in the longitudinal direction in the end face is a machining end face that is machined so as to differ depending on the position in the height direction orthogonal to the longitudinal direction, and the machining end faces correspond to each other. Therefore, when the end surfaces are brought into contact with each other and welded, the position where heat is generated by welding can be dispersed in the longitudinal direction of the gantry structure for a train line, and the stress caused by the heat can be reduced. Therefore, it is possible to prevent the train line gantry constituting body from being deformed when the processing end surfaces of the train line gantry constituting body are welded to each other. As a result, the holding surface for holding the trolley wire can be formed flat.

  The connection structure of the gantry structure for a train line according to the present invention can be roughly divided into several modes.

  One aspect of the connection structure of the train line gantry structure according to the present invention is such that the processing end surface of the one train line gantry structure and the processing end surface of the other train line gantry structure are in the longitudinal direction. A part or the whole of the inclined surface inclined with respect to is provided. In another aspect, the processing end surface of the one train line gantry construct and the processing end surface of the other train line gantry construct have a vertical surface extending in the height direction, and a horizontal plane extending in the longitudinal direction. Are formed in a staircase shape. According to still another aspect, the processing end surface of the one train line gantry structure includes a recessed portion that is recessed in the longitudinal direction, and the processing end surface of the other train line gantry structure protrudes corresponding to the recess. It has a convex part.

  According to each aspect of such a processed end face, it is possible to disperse the position where heat is generated during welding in the longitudinal direction of the gantry structure for a train line, thereby reducing the stress caused by the heat.

  In the connection structure of the gantry structure for a train line according to the present invention, the overall length of the joined end surfaces may be longer than the dimension in the height direction and 3 times or less.

  According to the present invention, when the end surfaces of the train line gantry structure are brought into contact with each other and welded, the position where heat is generated by welding is dispersed in the longitudinal direction of the train line gantry structure, and the stress caused by the heat is reduced. Can be lowered. For this reason, even if an unskilled worker performs the connection work of the train line gantry structure, the end surfaces of the train line gantry structure can be connected without deforming the train line gantry structure. As a result, the holding surface for holding the trolley wire can be formed flat.

  Further, since the train line gantry constructs are connected by welding without using bolts, no gap is formed between the train line gantry constructs. Therefore, in the completed rigid train line platform, the holding surface that holds the trolley line is formed flat at the connection portion between the train line platform structures. In addition, since the positional deviation of the trolley wire frame structure caused by the loosening of the bolts with time does not occur, the holding surface for holding the trolley wire can be maintained flat for a long period of time.

  The connecting structure of the train line gantry structure is such that the total length of the processed end face 10g, which is the sum of the lengths of the two slopes 11g and 12g constituting the recess 13g, is the height dimension H of the train line gantry structure 2g. It is formed so as to be longer than 3 times the height dimension H. Similarly, the total length of the machining end face 10h, which is the sum of the lengths of the two slopes 11h, 12h constituting the convex portion 13h, is longer than the height dimension H of the train line gantry structure 2h, and the height dimension H It is formed to be 3 times or less.

  The connection structure of the train line gantry structure according to the fourth embodiment is also connected by welding the processed end surfaces 10g and 10h formed on the two train line gantry structures 2g and 2h. Moreover, since each processing end surface 10g, 10h is formed so that the position in the longitudinal direction X in the processing end surfaces 10g, 10h differs depending on the position in the height direction Y, heat generated by welding is dispersed in the longitudinal direction X. To do.

[Fifth Embodiment]
A connection structure of a gantry construct for a train line according to a fifth embodiment of the present invention will be described with reference to FIG. Also in the fifth embodiment shown in FIG. 7, the processing end surface 10j of one train line gantry construct 2j has a recess 12j recessed in the longitudinal direction X, and the other end of the train line gantry construct 2k is processed. This is one mode in which 10k has convex portions 12k corresponding to the concave portions 12j.

  The processing end surface 10j of one of the train line frame structures 2j arranged on the left side of FIG. 7 includes a concave portion 12j that is recessed in a circular shape toward the left side of FIG. The processed end face 10j includes short vertical surfaces 11j and 13j on the upper side and the lower side of the recess 12j. On the other hand, the processed end surface 10k of the other trolley wire frame structure 2k disposed on the right side of FIG. 7 includes a circular convex portion 12j corresponding to the concave portion 12j. This processed end surface 10k also includes short vertical surfaces 11k and 13k on the upper side and the lower side of the convex portion 12k. The concave portion 12j and the convex portion 12k are formed so that the radius of the concave portion 12j and the radius of the convex portion 12k are substantially the same so as to correspond to each other. However, the radius of the convex portion 12j is slightly smaller than the radius of the concave portion 12j, and the convex portion 12k is inserted into the concave portion 12j.

  In such a connection structure for the train line gantry structure, the circumferential length of the recess 12j constituting the machining end surface 10 of one of the train line gantry structures 2j, and the vertical positions located above and below the recess 12j. The total length of the lengths of the surfaces 11j and 13j is formed to be longer than the height dimension H of the train line gantry structure 2j and not more than three times the height dimension H. Similarly, the circumferential length of the convex portion 12k constituting the processed end surface 10k of the other rail line gantry structure 2k, and the lengths of the vertical surfaces 11k and 13k located above and below the convex portion 12k Is formed to be longer than the height dimension H of the train line gantry structure 2k and not more than three times the height dimension H.

  The connection structure of the train line gantry structure according to the fifth embodiment is also connected by welding the processed end faces 10j and 10k formed on the two train line gantry structures 2j and 2k. Further, since the respective machining end faces 10j, 10k are formed such that the positions in the longitudinal direction X in the machining end faces 10j, 10k differ depending on the positions in the height direction Y, heat generated by welding is dispersed in the longitudinal direction X. To do.

  As mentioned above, since the heat generated by welding disperses in the longitudinal direction X in the connection structure of the gantry structure for a train line according to the present invention, the stress generated by the heat can be reduced. Therefore, it is possible to connect the end faces of the train line gantry structure without deforming the train line gantry structure. As a result, the holding surface for holding the trolley wire can be formed flat.

  Further, since the train line gantry constructs are connected by welding without using bolts, no gap is formed between the train line gantry constructs. Therefore, in the completed rigid train line platform, the holding surface that holds the trolley line is formed flat at the connection portion between the train line platform structures. In addition, since no bolts are used, there is no displacement in the connecting part of the train wire gantry structure caused by the loosening of the bolts over time, so the holding surface that holds the trolley wire over a long period of time is flat. Can be maintained.
