LHZ Heavy Duty Travelable Trolley Column Manual Revolve Welding Manipulator

1.       Working of Heavy duty Moving Welding Column and Boom at Customer Site:

1)      The attached and below small photo gives appearance on how does Heavy duty Welding Manipulator operating at customer workshop:  (Fig.1)

Large diameter tanks were being laid on Welding Rotator in a row. With traveling of Moving Welding Manipulator along its rails, the tanks can be completed welding external and internal longitudinal and circumferential seams. This is a typical Welding Center applied in Petrochemical Industry;

2)      The column rotation is not frequent under such scenarios. So, these Heavy duty Tank Welding Equipment are manufactured with manual revolve.

2.       Design Sketch of Heavy duty Moving Welding Manipulator:

1)      The heavy duty Welding Column & Boom of this product section is equipped with moving trolley. Compared with Stationary Welding Manipulator, traveling configuration trolley is more often seen in application of these Heavy duty Tank Welding Equipment;

2)      Just as reference, below is draft sketch of a set of LHT heavy duty Moving Welding Manipulator:  (Fig.2)

3.       Structure and Characteristic of Heavy duty Moving Welding Column and Boom:

A.      Mechanical System of the Welding Column & Boom:

1)      Mechanical system of LHZ model Welding Manipulator mainly consists of upright column, horizontal boom, cross slides saddle, and moving trolley;

2)      Boom elevating motor is installed at top of the column, which drives boom up and down with the transmission of chain sprocket, to adjust welding position in the Welding Center;

3)      Elevating motor installed into Welding Column and Boom is braking type, guaranteeing accurate and firm stop positioning of the boom, also avoiding hidden risk of creeping, in the working period of the Tank Welding Equipment;

4)      Cross Roll Bearing: Bottom of upright column is assembled into travelable trolley by way of cross roll bearing (slewing support), driving the boom rotation in the horizontal plane, realizing fitting and welding on several pieces of workpieces one time, in this set of convenient Welding Column & Boom: (Fig.3) 

5)      Cross Slides Saddle of the Heavy duty Welding Manipulator:  (Fig.4)

a)       Boom is mounted onto column thru saddle, fulfilling its vertical and horizontal smooth movement. The front head of boom is fit with motor drive cross slides of welding torch, and its end is fit with wire spool, gaining balance of the Welding Manipulator;

b)      Welding wire is joint to the welding torch by way of the wire linear on the welding arm. In this way, forming the welding supplementary unit of the Welding Center;

B.       Welding System in the Welding Manipulator and Welding Center:

Taking SAW (Submerged Arc Welding, which accounts for majority use in Tank Welding Equipment) as example:

1)       SAW Power Source: Optional Brand: Sweden ASAB/ U.S.A. Lincoln/ Chinese HUAYUAN;

2)      SAW Wire Feeder: Equipped together with welding power source;

3)       Flux Recovery Unit: Chinese LianTong;

4)      Welding Seam Tracing unit: Optional, Chinese I&D;

5)   Video Monitor: When the Welding Column and Boom carry out internal welding inside small diameter cylinder workpiece, which is difficult to get access;

C.      Electric System of Heavy duty Moving Welding Manipulator:

1)       Control system of this Welding Center combining Welding Manipulator and Welding Rotator is integral style, mainly composed of control board, operating panel, remote control pendant, and interface with welding units listed above, as well as with other welding equipment;

2)      Brand of the electric control components used in this high quality Welding Center is renowned ones, such as SIEMENS, Schneider, etc.;

3)       Control cabinet is dust proof and ventilating, IP40.
