Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As depicted in figs. 1 and 2, a kind of Full-automatic reverse of the utility model pushes away main jacking device, including support 1, pressing plate 2, cover plate
3rd, top iron assembly 4, block 5, main top oil cylinder 6, rotary oil cylinder 8 and proximity switch 9；The main top tailpiece of the piston rod of oil cylinder 6 is solid by pressing plate 2
It is scheduled on support 1, main top oil cylinder 6 is provided with clamp；Block 5 is placed on by cover plate 3 in the circular hole slot of top iron assembly 4, block 5
Inside is provided with groove, by rotation, and clamp can be stuck in the groove inside block 5 on main top oil cylinder 6；The cover plate 3 is fixed on top
On iron assembly 4；The two ends of rotary oil cylinder 8 are hinged with block 5 and top iron assembly 4 respectively；The proximity switch 9 is located at gear respectively
At the extreme position and the flexible two limit positionses of main top oil cylinder 6 that block 5 rotates.
On the basis of said structure, as shown in figure 1, main top oil cylinder 6 is provided with 2, clamp is arranged on outside the main top cylinder barrel of oil cylinder 6
The top and the bottom of side, two main top oil cylinders 6 are each passed through the hole for the circular strip rectangular channel that the both sides of top iron assembly 4 are left, the circular hole of block 5
Center and the main top center of oil cylinder 6 are concentric.The short axle being hinged with rotary oil cylinder 8 is fixed with block 5, rotary oil cylinder 8 can drive gear
Block 5 is around the main top central rotation of oil cylinder 6.It can be arc either plane to be at its rear backrest of medium-height trestle 1.Respectively to applied to circle
