b) Nearly all the common adopted welding mode: SAW, GMAW, Strip Cladding, TIG... can be equipped into this Tank Welding Equipment.

 
 

2. The Other Name of Welding Column and Boom:

1) Here the boom acts as machine hand, or manipulator, of the Tank Welding Equipment. This is the reason that, LHZ series Welding Column and Boom has the other name of “Welding Manipulator”;
2) The movement of horizontal boom in X axis along horizontal direction, and Y axis along vertical direction, composes core movement in Welding Column and Boom, which is realized with the delicate design sophisticated cross slides;
3) Communicated with other Welding Equipment, such as Welding Positioner, or Welding Rotator, the Welding Manipulator works in the form of various types of Welding Center;
 

4) The cross slides works as pivot in this Tank Welding Equipment, shown in below:

Fig2 Cross Slides Column and Boom -17- LHZ3030- 20130727_165246
5) This is the reason that, Welding Column and Boom is also called as “Cross Slides Column and Boom”.
 
 

3. How to Select Suitable Model of Cross Slides Column and Boom:

1) The skeleton of a set of classical LHZ series Cross Slides Column and Boom is shown in below:

Fig3 Cross Slides Column and Boom 139- Structure 1

 

a) The max. height of horizontal boom in the Welding Manipulator, which is also valid vertical stroke of horizontal boom, is determined from max. diameter, or height of workpiece, to be welded in this Tank Welding Equipment;
b) The farthest extending of horizontal boom in Welding Manipulator, which is also its valid horizontal stroke, is determined from the max. length of workpiece;
c) For example, the model of LHZ5060 Welding Column and Boom refers to that, the largest workpiece to be welded in this Cross Slides Column and Boom is, diameter/ height is 5000 mm, and length is 6000 mm;

2) Besides, based on on-site process technology design, the Welding Manipulator can be:

a) Stationary, or with moving ability. The traveling scope of the Tank Welding Equipment is designated by customers;
b) The column can be non-revolving, or manual/ motor drive revolving;
c) These configurations amplify working range of the Welding Column and Boom.

Mechanical Property in Cross Slides Welding Manipulator

Below photo gives vivid show on packing a set of Wuxi JACK LHZ4060 heavy duty Welding Column and Boom:

63- LHZ4060 Welding Column and Boom
 

Mechanical systems play key role for successful running of this Tank Welding Equipment:
 

1) Horizontal boom and vertical column;
2) Delicate and ingenious designed Cross Slides;
3) High power smooth driving and transmission system

Horizontal Boom and Vertical Column in Cross Slides Welding Manipulator

1. Horizontal boom and upright column compose basic skeleton and trunk of LHZ series Welding Column and Boom. Its intensity and strength determine stability and reliability of entire set of the Tank Welding Equipment;
2. Both the components have rectangular cross section, and made from high strength thick thickness steel plates;
3. In heavy duty Welding Manipulator, the workmanship of boom and column determines quality of entire set of the Tank Welding Equipment in the largest degree;
 

4. When manufacturing Welding Manipulator, process technology on making boom and column can be summarized as:

1) First cut the steel plates into shape and size with CNC Plate Cutting Machine;
2) Then bend the plates into shape by means of Press Brake;
3) Next fabricate the parts into final shape;
4) Finally, have advanced heat treatment on parts, to have stress relief and gaining strength;
5. The guide rail, gear and rack, pivot cross slides, are all assembled onto Cross Slides of the Welding Manipulator.

 

Delicate and Ingenious Designed Cross Slides in Welding Column and Boom

1. The Function of Cross Slides in Welding Column and Boom:
 

1) In operation of LHZ series Welding Manipulator, by means of cross slides, the position relationship between boom and column can be adjusted at will flexibly, by means of the movement of horizontal boom:
2) With elevation of boom, the height level of welding torch at its front end can be changed, based on size/ diameter of workpiece of this Tank Welding Equipment;
3) With horizontal extending and retreating of boom, the operating reach of welding torch can be controlled;
4) Besides, when making longitudinal welding with LHZ model Welding Manipulator, boom transverse movement is also the movement of welding torch. This is the reason that, in operation of the Cross Slides Column and Boom, boom horizontal speed is controlled with inverter, and displayed in digital manner in real time.

 

2. The Structure of Cross Slides in Light duty, Medium duty, and Heavy duty Welding Column and Boom:

1) As can be seen from the above 3 photos, in LHZ series Welding Manipulator, the movement of boom in both way is by means of rolling friction force, instead of gliding friction force. This means, the contact between 2 moving surfaces is by way of rolling rollers, instead of touch directly;
2) Besides, the cross slides in different loading capacity Tank Welding Equipment are different: The 1st photo is the cross slides in light duty and medium duty Welding Manipulator; The 2nd and 3rd photos are the cross slides in heavy duty Welding Manipulator;

3) In light duty and medium duty Welding Column and Boom, the movement of boom in either direction is guided with 4 pieces of rollers, at 4 corners respectively: 

Fig1 Welding Column and Boom 10- LHZ2525- IMG_1394
 

4) In heavy duty Welding Column and Boom, the movement of boom in either direction is guided with 4 groups of rollers, each guiding point is composed of 3 pieces of rollers, encircling the guiding rail: 

Fig2 56- LHZ4040 Welding Column and Boom- IMG_0676

High Power Smooth Driving and Transmission System in Welding Column and Boom

1. Driving and Transmission Mode and Mechanisms in LHZ Cross Slides Welding Manipulator:
 

1) The 1st photo is on high power A.C. driving motor for boom up and down in this Tank Welding Equipment. It is usually installed at the top of column; And sometimes, to reduce total height of Welding Manipulator, the motor is installed at bottom of the vertical column, inside the base bed;
2) The 2nd photo is on the precise worm gear motor for driving boom horizontal movement;

3) The 3rd photo is on vertical transmission mechanism in light duty and medium duty Welding Column and Boom:

a) The light duty Welding Manipulator uses leadscrew as its vertical transmission element;

Fig1 Welding Manipulator 134- Leadscrew
 

b) The medium duty (And heavy duty) Welding Manipulator uses chains as its vertical transmission element.

Fig2 Welding Manipulator- 135- V-Guideway

2. Guiding Element in LHZ series Welding Manipulator:

1) In the 4th photo is the high precision cross roll bearing, for guiding and transmitting column revolve in Welding Column and Boom. It is a piece of advanced machined and heat treated circular bearing, combined with circular rack;
2) The 5th photo gives clear demonstration on guiding and transmitting elements, for linear movement of boom in Welding Column and Boom: It is guided with precision heavy duty rectangular cross section linear guiderail, and transmitted with high precision rack;
3) The 6th photo shows central guiding and transferring unit for boom movement in Welding Manipulator: The assembled Cross Slides.

Operation of Welding Manipulator

1. Safety Assurance in Operation of Welding Column and Boom:

1) The 1st photo gives part of safety mechanisms in LHZ series Welding Manipulator:
 

a) The biggest safety hidden risk in Welding Column and Boom is sudden falling of boom from high level. To prevent this from happen, there is a row of rectangular holes in vertical column of the Welding Manipulator. If ever chains breaks off and lead to falling of boom, the rachet safety pins will be ejected out, holding the boom in that position. As marked in yellow frame in the 1st photo;
b) The climbing ladder alongside column in Welding Manipulator is surrounded with protection rails, as shown in orange frame in the 1st photo;
2) The boom lifting motor in Welding Column and Boom is braking type;
3) For more information on safety measures taken in LHZ series Welding Manipulator, please visit product section of “Industrial Use Welding Column and Boom”.


2. Operation of LHZ series Welding Column and Boom:

1) The 2nd photo shows welding head in LHZ Integral Control Welding Manipulator: The control console of welding power supply, seam tracker, and wire feeder are all installed here, for convenience of management on precise running of the Welding Column and Boom;
2) The 3rd photo was taken on welding head and control board in another set of Wuxi JACK Welding Manipulator;
3) The 4th photo shows operating pendant of the Welding Manipulator. This helps operator managing the Welding Manipulator in further distance and flexible working points.
