LHZ Medium Duty Fixed Base Column Electric Revolve Welding Manipulator

Quantity:

The three key words describing the product of this section is: medium duty/ fixed base/ electric revolve. It is a medium duty welding column and boom with automatic revolving.

 

   1.  Application of Medium size automatic column and boom:

     1) With boom traveling stroke enlarged from 2m to 4m of both 2 ways, workpiece of this cross slide weld

        manipulator is also turned from pipe/ tube to tank and other large diameter vessels;

     2) This is the reason sometimes the equipment is called tank welding machine;


    2.  Column Revolve of this Stationary Welding Column and boom

     1) It is motor drive, of braking motor;

     2) Transmission chain is braking motor –- gear –- slewing support unit – column;

     3) Operation is by means of the pushbutton on operating panel;


   3. Workpiece loading &unloading

    1) For stationary high precision column and boom, its max. reach is the workpiece around it;

    2) So, workpiece should be sent to working station utilizing auxiliary unit, such as travel crane and sling;


    4.  Welding mode of Column and boom for tank welding

    1) Majority is with submerged arc welding, making the equipment a set of welding column & boom with SAW;

    2) Sometimes for welding anti-septic layer or anti-abrasion layer of workpiece, the equipment is equipped with

      strip surfacing power supply, making it a set of welding column and boom with strip cladding. (Note: For this

      specific kind of welding mode we will have one product to have introduction on it purposely in the later 

      sections);


   5.  Saddle of boom travel

    1) It has another name of cross slide;

    2) We have a discussion on its structure and principle in the former product of manual revolve automatic 

       column and boom;

    3) Please check below picture. It shows how it looks when fit onto the equipment:

Cross slide fit

     4) As can be seen from the above picture, boom is installed between the upper and lower 2 arrays of rollers at

       the front side of the saddle. Or, in other words, top and bottom surfaces of the boom is snapped between the

       4 rollers. In this way, horizontal movement of the boom is guided;

     5) The same is truth with elevating movement of the boom: the external surfaces of column guideway are 

       snapped between the left and right 2 arrays of rollers at the rear side of the saddle;

     6) To have more precise management of boom travel, these rollers are the kind of eccentric rollers, which

       means inching control available, making the equipment a genuine sense of accurate welding column and 

      boom.
