Description

  The present invention relates to a movable bracket that supports a train line, and in particular, when an existing movable bracket is damaged due to an accident or the like, it is assembled and installed at the site to restore at least the train line support at an early stage. The present invention relates to a movable bracket that can be assembled as it is.

  A train line for supplying electricity to a train is generally composed of a trolley wire that supplies electricity to the train by direct contact with the pantograph of the train, and a suspension line that supports the trolley wire from above. This train line is supported on the track by a movable bracket that extends horizontally from a column installed beside the track toward the upper side of the track. The movable bracket typically includes a main body integrally assembled from a member such as a pipe, a curve pulling tool, and a suspension wire support. The movable bracket body is attached to the track-side column via an insulator, and the suspension wire support attached to the upper part of the movable bracket body supports the suspension line, and the curved line attached to the lower part of the movable bracket body. The tool supports the trolley wire. The trolley line needs to be installed at a certain distance from the center line in the traveling direction of the train to the side of the column or opposite to the column for the purpose of preventing local wear of the pantograph of the train in contact with the trolley line. . For this purpose, there are several types of curve drawing tools, such as an I-shaped curve drawing tool that pulls the trolley wire toward the support column, or an O-shaped curve drawing tool that pulls the trolley wire on the opposite side of the support column. The pulling tool is attached to the movable bracket so as to alternately draw a trolley line in the opposite direction for each movable bracket in the traveling direction of the train.

  By the way, train tracks are laid in various places such as straight sections, curved sections, and station premises. Closest to the track of the column because the location where the column to install the movable bracket is installed, the direction to draw the trolley line (hereinafter referred to as “trolley line drawing direction”), and the height at which the suspension line can be installed differ depending on the track laying location. The distance from the point to the trolley line (hereinafter referred to as “M gauge”), the mounting direction of the curving tool, and the distance between the suspension line and the trolley line (hereinafter referred to as “overhead height”) are various. In the conventional movable bracket, the movable bracket main body, the curve drawing tool, and the suspension wire support are integrally formed and installed individually in accordance with these various installation conditions. That is, a conventional movable bracket body having a length of about 1.8 m to about 4.2 m is created according to the M gauge at the installation location. In this movable bracket body, depending on the installation conditions, I type used for the location where the trolley wire is pulled to the column side, O type used for the location where the trolley wire is pulled to the opposite side of the column, and the parallel part of the train line Five types of curve-drawing tools are attached: a P-type used at a place for supporting the detention cable, and a special O-type and a special I-type used in combination with the I-type and the O-type. Further, since the overhead height is 710 mm in the station premises and 960 mm between the stations, the movable bracket main body has a main space between the trolley wire support portion of the curve pulling tool and the suspension wire support portion of the suspension wire support tool. A size of 710 mm and a size of 960 mm are created. Considering these combinations, the number of necessary movable brackets is 100 or more.

  Thus, when a movable bracket having many types is damaged due to an accident or the like, conventionally, the recovery is performed by the following procedure. First, a railroad company employee or the like identifies the location of the damaged movable bracket, visits the location, and confirms the M gauge of the damaged movable bracket, the mounting direction of the curving tool, and the height of the bracket. After that, it is checked whether or not the same type of movable bracket as the damaged movable bracket is stored in the company, and if the same type is found, it is transported to the site and installed. If the same type of movable bracket is not found, ask the manufacturer to manufacture the temporary movable bracket using a usable member, a log, or an insulating ladder among the members of the damaged movable bracket. Temporary recovery is performed by creating and installing.

  Further, Patent Literature 1, Patent Literature 2, and Patent Literature 3 are known as conventional movable brackets. Each of these movable brackets has a structure in which a main body assembled in advance using pipes of various lengths, a trolley wire support, and a suspension wire support are integrally fixed.

  However, in the conventional recovery procedure, even if the same type of movable bracket as the damaged movable bracket is stored in-house, etc., the type of the damaged movable bracket is judged, the same type is searched for, Since it takes time to transport, it took time from the occurrence of damage to recovery. If a movable bracket of the same type as the damaged movable bracket is not stored, it takes more time to order the movable bracket from the manufacturer and deliver it. However, the train passing through the temporary restoration site needs to be driven slowly, which may cause disruption of the operation schedule. In addition, if the movable bracket for this equipment is completed after temporary restoration, the movable bracket will be transported again to the temporary restoration site, the temporary movable bracket will be removed, and the time for installing the movable bracket for this equipment. Labor was also required. Furthermore, the currently used movable bracket has a short length of about 1.8 m, a long length of about 4.2 m, and a weight of about 60 kg. Although it is necessary, for example, when it is necessary to transport such a vehicle to a site where such a vehicle cannot be easily approached, such as a mountainous area, there is a problem that it takes more time to recover.

  In addition, the conventional movable brackets disclosed in Patent Document 1, Patent Document 2, and Patent Document 3 are all transported in a state where the main body is divided, and a necessary configuration is selected on the spot according to the installation conditions at the site. It is not a structure that assumes assembly. Further, in any of the movable brackets in the above-mentioned patent document, the curving tool that supports the trolley wire (for example, the member 5 and A1 in FIG. 1 of the patent document 3) changes the mounting position and the mounting direction to the main body. Although it can be done, the mounting position of each bracket can be changed because the curving tool is attached to the lower pipe of the bracket body (for example, member 4b in FIG. 1 of Patent Document 3). The range is narrow. Therefore, even if these prior art movable brackets are used, it is still necessary to prepare many types of movable brackets.

  In order to solve the above problems, an object of the present invention is to provide a movable bracket kit that can be assembled. The movable assembly bracket kit according to the present invention can be installed in any place without preparing many kinds of movable brackets by combining the components in the kit appropriately in the field.
