Description

【考案の詳細な説明】〔産業上の利用分野〕下端に電車線を備えたＴ形架台を電車線路とし
て利用する場合、カント角を有する箇所では電車
線の偏摩耗をかけるため、Ｔ形架台をカント角に
対応して傾斜取付けせねばならない。本考案はそ
の際用いる架台支持装置に関するものである。[Detailed description of the invention] [Industrial field of application] When using a T-shaped trestle with a contact wire at the lower end as a contact line, the T-shaped trestle is used because the contact wire wears unevenly at locations with cant angles. must be installed at an angle corresponding to the cant angle. The present invention relates to a pedestal support device used in that case.

[Conventional technology]

と思われる状態のとき、上記締付ボルトにより、
枠体を本体へ一体化させる。 As a frame support device for the same purpose, it was developed in 1983.
153232 is publicly known. The main body is fixed to the lower end of a vertical threaded rod, a frame body with a window through which the main body can be freely inserted is pivotally attached to one end of the main body, and a tightening bolt that passes through the main body and the frame horizontally is used to The two are integrated at a tilted position. The frame is tightened to the frame using saddles attached to both ends of the frame. When the worker seems to have lifted the T-shaped pedestal and tilted it appropriately, the tightening bolt
Integrate the frame into the main body.

[Problem that the invention attempts to solve]

架台は長さの長いものであるから、作業者がこ
れを持上げ処定角度に傾斜させることは、かなり
重労働であり、角度の微調節を行うことは至難で
あつた。 Since the frame is long, it is quite labor intensive for the operator to lift it and tilt it to a predetermined angle, and it is extremely difficult to make fine adjustments to the angle.

このため本考案では枠体を傾斜角度を顧慮する
ことなく支持装置へ取付け、その後にねじの利用
で角度調節を容易に行えるようにした。 Therefore, in the present invention, the frame is attached to the support device without considering the inclination angle, and the angle can then be easily adjusted using screws.

れ、他辺でＴ形架台Ｗのウエブを支持する。 The drawings will be explained. A threaded rod 1 is suspended from the ceiling via an insulator G. The fixing fitting 2 has a clevis protrusion 2a on one side of an inverted cup-like body and an arm 2b on the other side, and has a hole in the upper surface into which the threaded rod 1 can be inserted, and a hole into which the threaded rod 1 can be inserted. It is fixed with a nut. An oval hole 2c is bored in the arm 2b. The rectangular frame 3 includes a window into which the fixing fitting 2 can be freely inserted, and is pivotally mounted on one side of the window by a shaft 4. Also, there are bolt seats 3 on each end side.
A is formed. The locking pin 5 is fixed in the window perpendicularly to the long side of the frame, and has a nut 5a formed at a position corresponding to the oval hole 2c of the arm. The adjustment bolt 6 passes freely through the oval hole 2c, and its lower end is screwed into the nut 5a. By adjusting the upper and lower nuts 7 that sandwich the arm 2b, the angle α of the frame relative to the arm can be freely adjusted and fixed. Left and right 1
Each pair of saddles 8 is fixed to the bolt seat 3a on one side, and supports the web of the T-shaped frame W on the other side.

部品点数も少なくてすむ。 Temporarily fasten the frame with adjustment bolts to the fixing bracket installed below the insulator, lift the T-shaped pedestal, place it on the underside of the frame, and support it with both saddles.
All that is left to do is adjust the nut 7 to obtain any desired inclination angle α. The work is significantly simplified.
The number of parts can also be reduced.
