Description

  The present invention relates to a piping auxiliary device in a railway facility for assisting and supporting a pipe such as a steel pipe for passing cold water or a duct for ventilating cold air in a railway in a railway facility. And a piping method using the piping auxiliary device.

  When air-conditioning railway homes, for example, in central Tokyo station buildings, the store functions are integrated into a high-density facility, so heat source devices such as refrigerators are installed in remote locations away from the station building. In some cases, piping is laid along the track (track) from the installation location. In addition, in the planning of a railway station building, there is also known a method of laying a track first and then adding or constructing a station building as the number of residents increases thereafter. In preparation for such a case, if air conditioning pipes are laid in advance along the railway line, branch pipes are attached along with the addition of the station building, and the heat medium can be taken out, the construction plan will also improve the facility plan. Is also convenient. In addition, some of the station buildings that were built in the past do not consider cooling. To add a cooling function to such a station building, and to make the most of the space occupied by stores, etc., from the station building, Heat source equipment must be installed in remote areas.

  Under such a background, when piping is laid along a track, the piping must be laid at a position not in contact with the traveling railway vehicle, and the piping needs to be laid at a high place. Furthermore, in the case of renovation work that replaces existing piping, it is necessary to perform work at night when the vehicle stops traveling, and more rapid and rational work is desired. In addition, construction materials such as pipes and construction jigs need to be laid and transported to the construction site, and the work is finished because the inside of the track is narrow and construction materials and construction jigs cannot be left unattended. Each time you do, you must remove them.

  On the other hand, the following are known as techniques for conveying various materials and tools. The first technique is one in which a traveling girder is disposed so as to straddle a track via a support leg, and a hoisting machine is disposed on the traveling girder (see, for example, Patent Document 1). In the second technique, a vertically extending rail is installed on a building scaffold, and a casing is disposed so as to be movable up and down with respect to the rail (for example, see Patent Document 2). In the third technique, two conveyors are used. The gantry is arranged at a predetermined interval, and the conveyance gantry is moved up and down with a long member placed between the gantry (see, for example, Patent Document 3). A girder (bridge crane) is installed on two transport carts that can travel, and a branch machine or the like is transported by a winch disposed on the girder.

  However, in the first technique, a plurality of Yamakoshi units composed of support legs, traveling girders, etc. must be installed so as to straddle the track, and piping in the railway facility tunnel required to be removed at the end of work. The work requires a great deal of labor and time for installation and removal. In the second technique, since the rail is fixed and installed on the building scaffold and the position of the rail cannot be moved, when performing the work of laying the pipe along the track, the rail is moved along the entire track. Rails must be installed in advance, which is unrealistic.

  Furthermore, in the third technique, the operator simply raises and lowers the transport frame with a long member placed between the two transport platforms. When piping is laid at a high place in the tunnel, Scaffolds for performing the work must be installed separately, which requires a lot of labor and time. Further, in the fourth technique, it is necessary to prepare two transport carts equipped with girder, winch, etc., which increases the equipment and costs.
