UBZ12 U/ box beam assembling machine
1. Structure principle
This is the special equipemnt for bottom plate, web plate and baffle plate of box beam. It is composed of main machine, roller conveyor, centering device, positioning device, hydraulic system and electric control box.
Main machine is composed of moving boom, column, upper cross boom. Upper platform, upper press part, side press part.
The two moving boom have one motor reducer for each, driving the four moving wheel working, which form double driving system and make sure working stable.
There have guide rail on the column and upper cross boom, which make moving for side press part and upper press part. There have lifting oil cylinder on the top of vertical boom and driving the elevating moving of side press part. On two end of upper boom there have moving oil cylinder and driving horizontal moving of upper press part.
The upper press part is install on the guide rail of upper cross boom, it can make horizontal move on upper cross boom. The upper press part is composed of upper press oil cylinder, press head, slide base, C shape frame. It good advantage is the press force don’t reach to the roller, it is bearing by press head and C shape frame, which avoid there have heavy force damage the roller.
The side press part install on the vertical guide rail, it can make elevating moving along to the column. The side press part is composed of side press oil cylinder, press head, slide base. The backward force of side press part is transmission from moving boom guide wheel to moving guide rail. So the moving guide rail should be installing well.
Roller conveyor is including 6pcs roller conveyors, that is one drive roller conveyor drive five idler roller conveyors working at same time.
Centering device have one group 3pcs fixed on the roller conveyor. When working, adjusting the two slide arm by manual, closing to the bottom plate of box beam. Then hang the web plate to the slide arm. Make sure the web plate close to bottom plate and baffle plate .Last make sure all the plate are in center.
Positioning device have one group 3pcs fixed on the roller conveyor, staggered installation with centered device, the structure is similar with centering device, there have one forward/ reverse screw rod drive two positioning wheel moving at same direction and opposite direction. This makes sure the center position when U shape beam come back to the roller conveyor.
The hydraulic system install on the platform. Supply the power for upper press part, upper press moving oil cylinder, side press part, side elevating oil cylinder.
Electric control system is composed of electric control box and operation box. The electric control box install on the platform, two operation boxes install on the two side of column. The electric control box is not only control the forward/ reverse turning of moving motor, but control the electromagnetic valve of hydraulic station, and have the function that the hydraulic station control the press/ loose of upper press part, forward/backward of upper press moving oil cylinder, press/loose of side press part and elevating of side press elevating oil cylinder.

Packing list
 |
Box beam U assembling machine is used to assembling the 4 pieces of strip plate to form the box beam |
|
According to the processing features and requirement of box beam, the cover plates of 4 sides must be connected tightly with the internal reinforcing plates to avoid the out flowing of slag liquid when doing electro-slag welding. |
