Movable arm 3 comprises fluting 31, and fluting 31 is parallel with the longitudinal axis of movable arm 3, and coupling end and the movable end of fluting 31 are corresponding with coupling end and the movable end of movable arm 3 respectively; On the two side of the second end opposition of putting groove 21, one first connecting bore is set respectively, on the sidewall of the coupling end opposition of fluting 31, one second connecting bore is set respectively; The coupling end of movable arm 3 is inserted in the second end of putting groove 21, and the first connecting bore and the second connecting bore are connected to form hinged by the second axle body 5; Slot 31 and the bottom land wall of articulated position putting groove 21 is a breach.
The two side that hold down groove 11 opposes arranges respectively a screens, and corresponding two screens of two lateral walls of putting groove 21 are respectively arranged with a projection 23.Screens has two kinds of ways of realization, comprising: screens is the recess 13 that the top of the two side of the free end opposition of hold down groove 11 arranges respectively; Screens is the fixed orifice arranging respectively on the two side that opposes of hold down groove 11.
The free end of fluting 31 is provided with the first handle 32 that connects two madial walls.The lateral wall of putting groove 21 is provided with the second handle 22 for lifting.The width of putting groove 21 is larger than the width of movable arm 3, the consistency of thickness of the degree of depth of putting groove 21 and movable arm 3, and the length of the Length Ratio movable arm 3 of putting groove 21 is large.
Also comprise that the first adapter plate 61 and the second adapter plate 62, the first adapter plates 61 are fixedly connected with the end of the coupling end of hold down groove 11.The two ends of the first adapter plate 61 protrude from hold down groove 11 opposition two side and one first circular hole is set respectively, corresponding two the first circular holes of the second adapter plate 62 arrange respectively the second circular hole, the first circular hole is connected by screw and nut with the second circular hole.
The making sheet material of stand-type fork truck foldable heightening extension arm is that thickness is the steel plate of 4.5mm.
Application of the present utility model:
As shown in Figure 3, fixed arm 1 is vertically placed in to the upper surface of yoke 7 roots of fork truck, now, the first adapter plate 61 is placed in the upper surface of yoke 7, then the second adapter plate 62 is placed in to the lower surface of the yoke 7 of the first adapter plate 61 belows; Yoke 7 is all protruded at the first adapter plate 61 and the second adapter plate 62 two ends, and the first circular hole and the second circular hole protrude from yoke 7, finally fix by screw, nut respectively.Like this, just whole foldable heightening extension arm is fixedly mounted on yoke 7.
When installation, foldable heightening extension arm is folded state.Install, by second handle 22, projection 23 is taken out from recess 13 (when screens is fixed orifice, from fixed orifice, take out), then connecting arm 2 is outwards launched from hold down groove 11, finally movable arm 3 outwards being launched from putting groove 21, connecting arm 2 is placed on yoke 7 with movable arm 3 is smooth, is finally shown in Fig. 3.Forklift operator personnel can fork the larger goods of carrying size by this foldable heightening extension arm.Wherein, connecting arm 2 overall length after keeping flat with movable arm 3 is not more than the length of (yoke+yoke * 1/2).
As shown in Figures 5 and 6, after foldable heightening extension arm is finished using, folded placement.By mentioning first handle 32, movable arm 3 is rotated and put back in putting groove 21, the fluting 31 of movable arm 3 is relative with putting groove 21; Then connecting arm 2 unitary rotation are put back in hold down groove 11, putting groove 21 is relative with hold down groove 11; Subsequently, by second handle 22, connecting arm 2 is vertically moved, projection 23 is inserted in screens, make connecting arm 2 relative with fixed arm 1 fixing.In the time that screens is recess 13, when projection 23 is used in conjunction with recess 13, the position that projection 23 arranges is also relevant with the length of slot-like opening 12, when connecting arm 2 is in hold down groove 11 when perpendicular movement, the first axle body 4 can move in slot-like opening 12, and in the time that the first axle body 4 moves to the nadir of its path of motion, projection 23 can be stuck in recess 13.
In the time that screens is fixed orifice, projection 23 coordinates with fixed orifice; Connecting arm 2 unitary rotation are put back to after hold down groove 11, by second handle 22, connecting arm 2 is vertically moved, projection 23 is inserted in fixed orifice, make connecting arm 2 relative with fixed arm 1 fixing.
As shown in Figure 4, by the utility model, can fork the chassis 8 that size is larger.
The effect of part-structure:
Increase extension arm by fixed arm 1, connecting arm 2 and movable arm 3 three arms compositions, be then arranged on the yoke 7 of fork truck, realized increasing of prolongation to yoke 7 and yoke 7 entirety, transport larger-size object thereby can pitch.By two handles, can realize quick adjusting and increase extension arm, thereby prevent that operation from improperly causing damage to increasing extension arm.Projection 23 and screens, realized the movable arm 3 rear location of storage, improved the property easy to use that increases extension arm.Slot-like opening 12 is had living space the first axle body 4 and is driven connecting arm 2 up-and-down movements, makes screens easier with coordinating of projection 23.Adopt the steel plate of 4.5mm thickness to be applicable to field operation demand, its maximum bearing capacity is 3 tons; The deadweight of 4.5mm is little, convenient, flexible when operating personnel operates.Fixed arm 1 can be received connecting arm 2 and movable arm 3; Fixed arm 1 is directly connected with connecting arm 2, allows connecting arm 2 have firm power, and movable arm 3 and connecting arm 2 are steadily put off on yoke 7.Overall length after connecting arm 2 keeps flat with movable arm 3 is not more than the length of (yoke+yoke * 1/2), and the goods being forked just can not drop because of the problem of center of gravity fork truck.
The utility model is not limited to above-mentioned embodiment, if various changes of the present utility model or modification are not departed to spirit and scope of the present utility model, if within these changes and modification belong to claim of the present utility model and equivalent technologies scope, the utility model is also intended to comprise these changes and variation.
