本発明は、農用トラクタの転倒時に運転者を保護する安
全フレームの取付方法および装置に係るものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method and apparatus for attaching a safety frame that protects a driver when an agricultural tractor overturns.
安全フレームはその性質上極めて剛性を大きくする必要
があるので、各部材の重量も大きくなるうえ、転倒時に
運転者の生存スペースを確保する必要上運転席の上方を
覆うように装着されるものであるから、機体の地上高が
必然的に高くなるものである。Due to its nature, the safety frame must be extremely rigid, which increases the weight of each component, and it must be installed to cover the area above the driver's seat in order to ensure a survival space for the driver in the event of a fall. Because of this, the ground clearance of the aircraft inevitably increases.

フレーム１を機体の後方に仰天状態に倒した時における
連結金具４ｂの地上高を支持ビン６の地上高と同一にす
べく前方に屈曲形成されている。As shown in Fig. 3, the lower end of the rear wing 4 of the safety frame 1 is connected when the safety frame 1, in which the upper frame 3 and the rear wing 4 are coupled and fixed, is tilted backwards towards the rear of the aircraft. The metal fitting 4b is bent forward so that the height above the ground is the same as the height above the ground of the support bin 6.
次に叙上の如く構成した安全フレーム１の取付方法につ
いて説明する。Next, a method of attaching the safety frame 1 constructed as described above will be explained.
安全フレーム１を農用トラクタＡに取付けるにあたって
は、先ず前部伜２と上部忰３とを分離させ、前部枠２を
第３図に示すように取付板２ａを介して機体の所定位置
に固定した後、上部枠３と後部忰４とを結合固定した安
全フレーム１を機体の後方に仰天状態に倒しておく。To attach the safety frame 1 to the agricultural tractor A, first separate the front part 2 and the upper part 3, and fix the front frame 2 to a predetermined position on the machine body via the mounting plate 2a as shown in FIG. After that, the safety frame 1, in which the upper frame 3 and the rear frame 4 are connected and fixed, is tilted to the rear of the fuselage.
次に、農用トラクタＡを後退させてその後端下部に固植

させる。In this way, while the support bin 6 is engaged with the connection fitting 4b, the lift arm 7 and one of the connection bins 4d fixed to the rear frame 4 are connected via the lift rod 9, and the lift arm 7 is moved upward. The safety frame 1 is swung upward and rotated around the support bin 6 to a position a shown in FIG.
そして、ステ−１１等を用いて安全フレーム１を支え、
リフトロツド９の孔位置を変えて再び同図ｂ位置、すな
わち、安全フレーム１の重心が支持ビン６の上方近傍に
達する位置まで支持ビン６を中心として安全フレーム１
を上方に持ち上げ回動させる。Then, support the safety frame 1 using the stay 11 etc.
After changing the hole position of the lift rod 9, the safety frame 1 is moved around the support bin 6 until the center of gravity of the safety frame 1 reaches near the top of the support bin 6, which is the position b in the figure again.
Lift it upward and rotate it.
次に、リフトアーム８と他方の連結ビン４ｅとを別のリ

の取付けを終了する。In this way, the Anrei frame 1 is set in a predetermined position, the upper end of the front frame 2 and the front end of the upper frame 3 are fixed,
Furthermore, after fixing the lower end of the rear wing 4 to the fuselage via the mounting plate 4a, the lift rod 10 is removed and the safety frame 1 is removed.
Finish the installation.
なお、安全フレーム１を取外すときには、上記の手順と
逆の手順によって行うことができるため、従来のように
クレーンあるいはホイスト等を使用する必要が全くなく
、安全フレームを任意の場所で、しかも簡易かつ迅速こ
着脱できるものである。Furthermore, when removing the safety frame 1, the procedure described above can be reversed, so there is no need to use a crane or hoist as in the past, and the safety frame can be removed easily and easily at any location. It can be quickly attached and detached.
