Stationary And Movable BOX H Beam 90°/ 180° Turnover Cart

A. Function and Application of 90°/ 180° Hydraulic Drive BOX H Beam Stationary and Movable Turnover Machine:

1. 90° BOX H Beam Turnover Cart:

1) Task: Overturning H Beam/ BOX Beam in the range of 0 ~ 90°;

2) Where Used: In the process flow of automatic H Beam Production Line, the 90° Turnover Rack Equipment locates alongside output conveyor roller tables of H Beam Assembly and Tack Welding Machine. It is for flipping T Beam/ H Beam to the other side, so as to fitting up and have stitch welding on opposing side of T/ H Beam;

3) At Automatic H Beam Production Line: 90° Tipping Rack Machine turns over assembled H Beam on output conveyor of H Beam Assembly Machine: (Fig.1)

2. Stationary 180° BOX H Beam Overturning Cart:

1) Work Station: 180° Turnover Rack Equipment is installed at H Beam Flange Straightening Machine, following H Beam Assembly and Tack Welding (90° turning over) and Submerged Arc Welding Machine (60° turning over):

2) 180° Turning Over Rack Equipment at input conveyor roller tables of HYJ800 H Beam Flange Straightening Machine, EOL (End of line) station of automatic H Beam Production Line: (Fig.2)

3) Assistant Working Unit: For stationary 180° BOX H Beam Flipping Cart, moving unit need to equipped for H Beam conveying:

3. 180° BOX H Beam Movable Flipping Machine:

1) 4 Times Welding Operation: In the process of BOX H Beam production, there are 4 pieces of welding seams in one workpiece, which will be fabricated with 4 sets of LHC model H Beam SAW Welding Machine respectively: One set of LHC completes one piece of welding seam;

2) Transfer among LHC: At the completion of each time SAW welding, BOX H Beam will be flipped 90° or 180°, and sent to next set of LHC. This task is fulfilled by means of 180° BOX H Beam Movable Turnover Machine:

3) Large size welded H Beam being flipped and conveyed with 180° BOX H Beam Turnover Cart: (Fig.4)

B. Operation Principle of 90° and 180° BOX H Beam Stationary and Movable Flipping Machine:

Here we take 180° BOX H Beam Overturning Cart as example:

1. Manipulator Quantity: There are 2 pieces of L shape overturning rack in one set of the BOX H Beam Flipping Cart, for holding on long length of BOX H Beam, and workpiece 90° / 180° overturning at the completion of SAW welding operation:

2. Work Zone of 180° BOX H Beam Turnover Cart:

This equipment is placed at:

1) At SAW welding zone of automatic H Beam Production Line, between the 4 sets of LHC H Beam SAW Welding Machine, adjacent to 60° stationary turnover rack machine groups;

2) At H Beam Flange Straightening zone, alongside H Beam Flange Straightening Machine, for flipping H Beam 180° to the other side, to straighten on the other side of flange;

3) At SAW welding zone, between the 4 sets of column structure or moving gantry frame structure BOX Beam SAW Welding Machine:

4) 180° Steel Structure BOX H Beam Movable Flipping Machine holding on BOX Beam, at SAW machine of BOX Beam production line: (Fig.6)

4. Operation Mode of 180° BOX H Beam Overturning Cart:

1) Hydraulic Drive: Driven with 2 pieces of hydraulic oil cylinders, 2 pieces of rockshafts revolve in phase simultaneously, overturning and carrying BOX H Beam onto conveyor rack of SAW welding machine;

2) Convey H Beam: By way of lifting moving machine, BOX H Beam is sent to next set of SAW welding machines;

3) Movement of this 180° Movable Turnover Machine and BOX H Beam, is driven with motor reducer, and guided with moving wheels at the mechanical body. Its movement is along parallel rails:

C. Composition and Operation of 90°/ 180° Hydraulic Drive Steel Structure BOX H Beam Turnover Cart:

1. Main Units of BOX H Beam Movable Turnover Machine:

1) Mechanical base bed, BOX structure, stationary, at the bottom of the machine, being fixed into workshop at customer workshop;

2) Overturning L arms, its rotation is driven with hydraulic cylinders. Being assembled onto the mechanical base bed;

3) Revolving transmission shaft, being assembled inside mechanical base bed;

4) Hydraulic oil cylinder, also being assembled inside mechanical base bed;

5) Hydraulic pump station, being put individually alongside the BOX H Beam Overturning Cart, being connected with oil cylinder by means of hoses. Rotation of L arm is driven with hydraulic cylinder;

6) Electric control board/ operating panels;

2. Major Working Steps of 90°/ 180° BOX H Beam BOX H Beam Flipping Cart:

Here we also take 180° Movable Turnover Machine as example:

1) During operation, BOX H Beam is raised off 60° overturning racks of SAW welding Machine;

2) Then, driven with oil cylinder, rockshafts L shape racks of the machine overturn BOX H Beam 90° or 180°;

3) After that, BOX H Beam will be sent to elevating moving machine, and be transported to the next set of H Beam SAW Welding Machine, or H Beam Straightening Machine;

D. Strong Points of Wuxi JACK 90°/ 180° BOX H Beam Overturning Cart:

1. Cables and oil pipes of this machine are arranged through drag chain, applicable for complicated operation of workpiece rotation and convey. It has safe work, good appearance and reliable performance:

2. The entire set of BOX H Beam Turnover Cart has compact structure and easy operation, applicable for being applied in various automatic steel structure production line;

3. Flexible Operation: The lateral 2 sets of Steel Structure Overturning Racks rotate individually, serving as assistant supporting unit during welding process;

4. Flipping Angle Precision Control: Encoder is introduced in Wuxi JACK produced 60°/ 90°/ 180° BOX H Beam Movable Turnover Machine, for detecting on and identifying its L arm flipping angle;

5. Ingenious Design on Wuxi JACK BOX H Beam Movable Turnover Machine:

Prevent H Beam from Falling Down: There is a small rack being fit on each of the L arm. Its usage is to reliably hold the “┷” Beam onto Turnover Rack, and preventing H Beam from unexpected falling down, during L shape Tipping Rack tilting:

1) Small protection brackets being assembled onto Tipping Rack of Wuxi JACK 90° BOX H Beam Turnover Cart: (Fig.11)

2) Flexible Position Change along Turnover Rack: Based on size of the “┷” Beam，there are three shifts of mounting positions for the small rack on the L arm Tipping Rack, in the form of 3 groups of holes.

E. Put into Use on 90°/ 180° Steel Structure BOX H Beam Turnover Cart:

1. Installation: During installation of automatic H Beam Production Line, mechanical base of BOX H Beam Movable Turnover Machine is fixed into workshop floor with anchor bolts;

2. Application Form: Same as 60° unit, the 90° unit also works in 3 sets per group:
