Specific embodiment
Fig. 1~Fig. 4 is preferred embodiment of the invention, tail arm and balance horse which show counter lift truck
Leg combining structure is brand-new component, and it is made up of tail arm and balance horse leg, it is characterised in that：Tail arm is mainly
It is made up of two oil cylinders and its supporting construction, as shown in Figure 1, 2.The oil cylinder 1 of control tail arm rotation passes through
Rotary shaft 1 (5) connects together with fixed mount 9, and the flexible oil cylinder 2 of control tail arm is placed in oil cylinder support beam 3
Interior, telescopic oil cylinder 2 and oil cylinder support beam 3 share a rotary shaft 6, and are connected in by the axle 6 and fixed mount 9
Together, telescopic oil cylinder support beam 3 and rotary oil cylinder 1 are connected to one by fixedly connected part 4 and connecting shaft 7
Rise, lock shaft 8 is fixed on the end of telescopic oil cylinder 2, and fixed mount 9 is bolted on automobile spandrel girder 10,
On, whole tail arm is suspended on automobile spandrel girder 10 by fixed mount 9, while left and right telescopic oil cylinder support beam
3 are rigidly connected by synchronous beam 11.Additionally, tail arm also has hydraulic distributing valve, synchronous valve, hydraulic pressure
The hydraulic control architectures such as lock.
Tail arm operation principle：
Specified valve rod in manually operated 1 × 4 hydraulic distributing valve, starts rotary oil cylinder 1, makes whole oil cylinder 1
Rotated around rotary shaft 1 (5), then oil cylinder connecting rod end will be by connecting shaft 7 and fixed company
Fitting 4 drives telescopic oil cylinder support beam 3 to be rotated around rotary shaft 2 (6), and telescopic oil cylinder 2 can be with
Telescopic oil cylinder support beam 3 rotates together, now, another specified in 1 × 4 hydraulic distributing valve of operation
Valve rod, can make the telescopic arm of telescopic oil cylinder 2 move reciprocatingly, then positioned at the telescopic arm end of telescopic oil cylinder 2
It is exactly compound motion that the lock shaft 8 in portion is taken exercises, and movement locus is by with 2 (6) circumference as the center of circle of rotary shaft
The vectorial combination of the linear motion of motion and oil cylinder telescopic arm.By two combined operations of oil cylinder valve rod, make
Lock shaft 8 presses the motion of pre-determined route track.
The effect of tail arm is to support rising and falling for container, it is therefore desirable to which the tail arm of left and right two is kept strokes, the present invention
Ensure the consistent of two tail arm action in terms of two, one is left rotation and right rotation oil cylinder and telescopic oil cylinder by one
The control of individual hydraulic valve stem, while be mounted with synchronous valve, two is left and right telescopic oil cylinder support beam 3 by synchronous beam 11
It is rigidly connected.
Tail arm is the effect by hydraulic coupling supports the weight of container, because the weight of logistics container is frequent
It is very big, to ensure load-bearing safety of the container during rising and falling, the tail arm when underground is ineffective suddenly
The weight of container can be still born, this structure have also been devised hydraulic lock, not weightless this guarantees decompression.
The tail arm and balance horse leg combining structure of foregoing counter lift truck, it is characterised in that：Equalizer bar
27 is a square steel for two side chamfers, and two ends are linked together by rotary shaft 24 with balance horse leg 21, side
The inside of steel equalizer bar 27 left and right is respectively equiped with 1 hydraulic jack 22, and the interlinking lever end of hydraulic jack 22 is by connecting
Spindle 25 links together with balance horse leg 21, and the above is as an entirety by fixing suspension bracket 23 by bolt
It is fixed on automobile spandrel girder 26.When horse leg works, the contact point on horse leg and ground, rotary shaft 24 and
The three-point shape of connecting shaft 25 subjects the pressure from lorry into a three-legged structure for stabilization by equalizer bar 27
Power, when horse leg rises, whole horse leg passes through fixed suspension bracket 23 and is suspended on automobile spandrel girder 26.
Horse leg operation principle：
Manually operated hydraulic distributing valve, starts hydraulic jack 22, and oil cylinder connecting rod end moves reciprocatingly, and drives
Connecting shaft 25 is moved in a circle centered on rotary shaft 24, and horse leg 21 and the relative position of connecting shaft 25 are constant,
So as to drive horse leg 21 to be moved in a circle centered on rotary shaft 24, the lifting of horse leg is realized.
Horse leg rises process：
The valve rod of horse leg hoist cylinder is controlled in manually operated 1 × 4 hydraulic distributing valve, hydraulic jack is made and is compressed
Motion, oil cylinder connecting rod drives connecting shaft 25 to move in a circle, so as to drive during horse leg 21 is with rotary shaft 24
The heart moves in a circle, and horse leg rises.
Horse leg descent is：
The valve rod of horse leg hoist cylinder is controlled in manually operated 1 × 4 hydraulic distributing valve, hydraulic jack is made and is expanded
Motion, oil cylinder connecting rod drives connecting shaft 25 to move in a circle, so as to drive during horse leg 21 is with rotary shaft 24
The heart moves in a circle, and horse leg falls.
