It is known that the vehicle is guided along the track while being guided in the opposite direction, and this technology is applied to a self-propelled bogie for transporting car bodies. It is considered that the

る。(Problems to be Solved by the Invention) Conventionally, track frames have been connected to each other at their joints by welding or by bolting flanges fixed to the ends of each track frame. On a production line, it is necessary to connect the track frames in a separable manner in preparation for line modifications, so welding is not possible, and with the method of bolting flanges together, it is necessary to secure each flange to the track frame by welding, etc. Therefore, the construction period and cost increase, and it is desirable to be able to connect the track frames by a simpler method.
本発明は、かかる要望に適合した軌道装置を提供するこ
とをその目的としている。It is an object of the present invention to provide a track device that meets such demands.

も良い。(Means for Solving the Problems) In order to achieve the above object, the present invention embeds a track frame having a guide rail for guiding a self-propelled bogie in the running path of the self-propelled bogie, and the track frame is It is composed of an extruded material with a dovetail groove continuous in the longitudinal direction of the raceway frame formed on the inner surface, and one raceway frame and the other raceway frame are connected to the dovetail groove of both raceways at the joint part of the raceway frame. The connection is made through an engaging dovetail joint member. In this case, a channel groove capable of accommodating a nut for fastening the guide rail may be continuously formed in the track frame in the longitudinal direction of the track frame.
（作 用）

材の一端側を係合させることで、該軌道枠に対し該継手
部材が該軌道部材の長手方向に直交する２方向即ち上下

材に対し該他方の軌道枠が上下方向と横方向に位置決め
され、かくて一方と他方の継手部材は該継手部材を介し
て上下左右に位置ずれすることなく正確に連結される。(Function) By engaging one end side of the dovetail-shaped joint member with the dovetail groove of one of the track frames to be connected to each other, the joint member is orthogonal to the track frame in the longitudinal direction of the track member. By positioning the joint member in two directions, that is, in the vertical direction and in the horizontal direction, by engaging the other end of the joint member with the dovetail groove of the other track frame, the other track frame is positioned in the vertical and horizontal directions with respect to the joint member. Thus, one joint member and the other joint member are accurately connected through the joint member without being displaced vertically or horizontally.

になる。Also, when modifying a line, the track frame buried in the modified part is separated from the track frame buried in the unmodified part and removed, but in this case, conventional technology in which the track frames are bolted together at the flanges at their ends does not work. Since the flange is embedded in the concrete layer in which the track frame is buried, separating the track frame takes time and effort.In contrast, with the present invention, the track can be removed by simply disengaging the joint member from the dovetail groove inside the track frame. The frames can be easily uncoupled, making removal work easier.

となり、工費の削減を図れる。In addition, it is desirable for the guide rail to be detachably attached to the track frame due to maintenance requirements, and in this case, it is possible to form a screw hole in the track frame and fasten the guide rail to this hole using bolts. However, this requires time and effort to process the screw holes, which increases costs. On the other hand, if a channel groove is formed in the track frame as described above and the guide rail is fastened to a nut housed in the channel groove, the machining of a screw hole is not required and the construction cost can be reduced.
尚、上記したあり溝やチャンネル溝は、軌道枠の押出し
成形時に形成されるもので、加工費によるコストアップ
は生じない。Note that the above-mentioned dovetail grooves and channel grooves are formed during extrusion molding of the raceway frame, so there is no cost increase due to processing costs.
