LHZ Heavy Duty Travelable Trolley Column Electric Revolve Welding Manipulator

1. Application of Heavy duty Electric Revolve Moving Column and Boom Welding Equipment:

1) Major Welding Machinery: The attached photos were taken at a modern facility, where produces medium to large scale pipelines and tanks. The main welding equipment adopted here are groups of Heavy duty Moving Welding Manipulator, and Welding Rotators;

2) Loading Capacity: Considering the heavy tonnage of workpieces tanks/ cylinders to be fabricated here, the Welding Rotators working with these Heavy duty Tank Welding Machine are usually HLK Bolt Adjusting Welding Roller Bed, which has loading capacity up to 1000 ton to 2000 ton;

3) This product section of Heavy duty Moving Column and Boom Welding Equipment wraps up our introduction on standard product of automatic Weld Manipulator. From next section we will go on introduction on special made models.

2. Executing Cells and Control Units in Heavy duty Moving Welding Manipulator:

A. Execution Unit in Travelable Welding Manipulator:

1) Horizontal Boom Transverse Moving at customer workshop: (Fig.1)

a) Horizontal Boom transverse travel is controlled with A.C. inverter and shown in digital display. The corresponding speed is adjustable welding speed;

b) By the transmission of gear and rack couple, the horizontal boom travel features in high precision and accurate positioning, guaranteeing on high level uniform finished product quality delivered from Welding Manipulator: 

Horizontal Boom elevation drive and transmission mechanism: (Fig.2) 

c) Top Level Components: The adopted gear reducer for driving horizontal Boom movement is produced by top grade professional supplier in the industry, of which lubrication is oil immersed enclosed style, eliminating invasion of slag/ dirt/ particle into the Column and Boom Welding Equipment, thus bringing forth advantages of maintenance free and long service life of the Heavy duty Tank Welding Machine;

2) Welding Torch Manipulation Mechanism in the Column and Boom Welding Equipment: (Fig.3)

The motor drive cross slides with torch fit on it can fully ensure accurate positioning of the welding torch, making sure accurate, stable and high standard welding performance from this Welding Manipulator;

3) Heavy duty Precise Square Guiding Rail: (Fig.4)

a) Square cross section shape high precision rails are used on both upright column and horizontal Boom of the heavy duty welding equipment;

b) These highly accurate guide rails are planed and grinded post annealing, fully guaranteeing on stability during welding of the Heavy duty Tank Welding Machine;

4) Cross Slides Saddle in Wuxi JACK Welding Column and Boom: (Fig.5)

a) Assembly Fit Up: The saddle is box structure in LHZ series Heavy duty Moving Welding Manipulator, of which its top is connected with the chain of horizontal Boom elevation unit, and its rear is mounted onto the upright column thru pulley, its front is fit with boom thru pulley;

b) Cross slides saddle is the critical moving joint during work period.

B. Electric Control System of Automatic Heavy duty Moving Welding Column and Boom:  

Electric control board: (Fig.6)

This electric control system can be divided into 3 segments of control elements inside control board, operating panel, and remote pendant:

1) Control Elements inside Control Board of Welding Manipulator:

a) The control elements inside the control board have contactors/ control transformer/ inverter, and terminals on it;

b) These units mainly serves as controlling on/ off of motor, performing motions of the welding equipment, and implementing on protection on the motor;

2) Operating Panel:

The components on the operating panel are: Digital speed display of boom horizontal speed, power lamp, power switch, boom travel button, boom elevating switch, inverter alarm lamp, etc.;

3) Remote Pendant: (Fig.7)

a) As can be seen from the above photo, these buttons/ switches include: Power lamp/ Boom speed pre-set/ Cross slides button/ Horizontal Boom travel button/ Welding on/ off button. The remote pendant is used for controlling operation of the machine conveniently;

b) By means of the operating panel and remote pendant, all the sections of the automatic welding equipment can be operated individually;

c) Besides, various parameters can be adjusted on practical condition, realizing integral control of the Welding Manipulator with its welding system, and other welding equipment, such as Welding Positioner.
