【考案の詳細な説明】
本考案は、固定枠と該枠に対して昇降自在な昇
降枠とに夫々クランプ腕を有するクランプ装置に
関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a clamp device that has clamp arms on a fixed frame and an elevating frame that can be raised and lowered relative to the frame, respectively.
従来装置では、クランプ作業以外の作業として
クランプ下腕に荷役物を搭載する場合、クランプ
上腕が昇降枠に固定されていたため、荷役物の高
さに制限を受け、高さの大なる荷役物を搭載でき
ないという欠点があつた。 With conventional equipment, when loading a cargo on the lower clamp arm for work other than clamping, the upper arm of the clamp was fixed to the lifting frame, so there was a limit to the height of the cargo, making it difficult to load objects with large heights. The drawback was that it could not be installed.
本考案は、上記の点に鑑み、クランプ上腕を昇
降枠に横軸を介して回動自在に枢支することによ

である。 In view of the above points, the present invention has been developed to provide a clamp that can lift various cargo objects without limiting the height of the cargo object by rotatably supporting the upper arm of the clamp to the lifting frame via a horizontal axis. The aim is to provide equipment.

る。 An embodiment of the present invention will be described below with reference to Figures 1 and 2. In the figure, 2 is a normal telescopic mast installed upright at the front of the vehicle body 1, and a lift bracket 3 is attached to the mast 2 to raise and lower it. A fixed frame 4 is fixed to the front part of the bracket 3, and a fork as a lower clamp arm 6 is fixed to the front part of the fixed frame 4 via a finger bar 5. The clamping device according to the present invention includes a fixed frame 4 with the lower clamp arm 6 attached, an elevating frame 7 that is attached to the frame so as to be able to rise and fall and whose ascent limit is regulated, and a rear end of which is lateral to the elevating frame. Clamp upper arm 9 rotatably connected via shaft 8
A lifting frame lifting cylinder 10 is connected to the upper arm 9 via a shaft 10b at a front position where the upper end of a piston rod 10a is eccentric to the horizontal axis 8, and a horizontally protruding cylinder 10 is provided at the rear of the upper end of the lifting frame 7. It is equipped with a stopper 11 for horizontal upper arm posture. In addition, 12 is a stopper for upper arm standing posture fixed to the lower side of the clamp upper arm 9 to the lifting frame 7, and 13 is a tension spring, which is clamped by the rise of the piston rod 10a of the cylinder 10 when the lifting frame 7 is raised. This is to prevent the upper arm 9 from moving upward around the horizontal axis 8. Note that since the center of gravity of the upper arm 9 is located considerably forward, this spring 13 may be omitted. Further, reference numeral 14 denotes a push plate 17 suspended from the lower part of the clamp upper arm 9 via front, rear, left and right shafts 15 and 16.
is a backrest frame fixed to the fixed frame 4.

常のクランプ作業姿勢をとることができる。 Next, the action will be explained. When the lifting cylinder 10 moves upward, the piston rod 10a rises and attempts to rotate the clamp upper arm 9 upward, but the clamp upper arm 9 maintains a horizontal position due to the spring 13 and the stopper 11, so that the horizontal axis The lifting frame 7 connected to the clamp upper arm 9 at 8 is the clamp upper arm 9
rises with If the piston rod 10a is further raised after the lifting frame 7 has reached its upper limit, the lifting frame 7 will not rise any further, so the first
As shown by the chain line in the figure, the clamp upper arm 9 moves upward around the horizontal axis 8 against the spring 13, and continues upward movement until the rear end of the upper arm 9 comes into contact with the stopper 12. Also, from the standing position of the clamp upper arm 9, the piston rod 10
When the upper arm 9 is lowered, the upper arm 9 of the clamp first moves downward, and then the upper arm is lowered together with the lifting frame 7 while maintaining the horizontal position by the horizontal position stopper 11, so that a normal clamping working position can be assumed.

持するので安定した荷役作業を行い得る。 Therefore, according to the present invention, it can be used not only for the work of clamping a load with the upper and lower arms of the clamp, but also for the work of transporting the load by loading the load on the lower arm of the clamp.
At that time, the upper arm of the clamp can be rotated at the lifting limit of the lifting frame, so there is no need to regulate the height of the loaded cargo.
This rotation mechanism can be realized by a lifting frame lifting cylinder connected to the upper arm at a position where the upper end is eccentric to the front side of the horizontal axis, and a stopper for horizontal posture of the upper arm provided on the lifting frame, so gears or the like are used. It can be manufactured at an extremely low cost compared to the conventional method, and when loading an object with a large height, the elevating frame supports the rear side of the object, so that stable cargo handling operations can be performed.
