Second cantilever, first swivel joint is two, arranged apart up and down, and the left end of first cantilever is by two first rotations
Adapter is arranged on the right side wall of column, and right-hand member is connected by rotary part with the left end of the second cantilever, and in the first cantilever
And second be disposed with balancer between cantilever；The right-hand member of second cantilever is folded upward at forming kink, in kink termination
It is provided with the second swivel joint that can be horizontally rotated；The liquid feeding gun breech portion lower section is provided with vertical steel pipe, the steel pipe
Top is connected to liquid feeding gun breech portion by union elbow, and the bottom of steel pipe is provided with hose coupling, and medium is from hose coupling
Flow through steel pipe, union elbow to enter in liquid feeding rifle, horizontal-extending support bar, the right side of support bar are installed with the side wall of steel pipe
End bends forwards, and connects the 3rd swivel joint that can be rotated vertically, and the 3rd swivel joint passes through " L " shape coupling assembly
It is connected with the second swivel joint, with the rotation of the second cantilever, drives liquid feeding rifle to rotate, and keep the horizontal of liquid feeding rifle axial direction
State.
On the basis of such scheme, the welded top of the steel pipe is in the bottom of union elbow, a left side for the support bar
End is welded on the right side wall of steel pipe.
The beneficial effects of the utility model are：(1), liquid feeding rifle can keep axial horizontality, carry out liquid feeding rifle and gun platform
It is not required to artificially adjust the horizontality of liquid feeding rifle during connection；And there is no liquid feeding rifle counterweight to stop operation between two handles of liquid feeding rifle
Personnel, it is more laborsaving, convenient to operate.
(2) weighing device, is not needed, the power suffered by the second cantilever is reduced, after stress reduction, the specification of balancer
Can accordingly reduce, i.e., the specification of the spring cylinder of balancer and spring all can accordingly be reduced, so as to reduce product cost.
Brief description of the drawings
Fig. 1 is front view of the present utility model.
Fig. 2 is the shaft side figure of liquid feeding rifle in Fig. 1.
Specific embodiment
Below by embodiment and with reference to accompanying drawing, the utility model is described in further detail：
It is illustrated with reference to Fig. 1~2 pair embodiment, the balance knot of liquid feeding rifle in a kind of LNG filling machines auxiliary filling mechanism
