LHZ Heavy Duty Travelable Trolley Column Manual Revolve Welding Manipulator

Quantity:

The heavy duty column and boom of this segment is with moving trolley. Compared with stationary type, traveling type is more seen in application of these heavy duty tank welding equipment.

Just as reference, below is draft sketch of a set of heavy duty moving column and boom:

Structure and Characteristic of Travelable Cross Slide Welding Column boom:

    1. Mechanical system:

     1) Mechanical system of this weld Column & boom mainly consists of column, boom, saddle and 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;

     3) This elevating motor is brake type, guaranteeing accurate positioning of the boom, also avoiding its possible

       creep, in the working process of this high quality tank welding machine;

     4) Bottom of column is fit into travelable trolley by way of cross-roll bearing (slewing support), driving the 

       boom revolving in the horizontal plane, realizing fitting and welding of several work-pieces one time, by this

       set of convenient welding manipulating machine;

     5) Boom is mounted onto column thru saddle, fulfilling its vertical and horizontal control. The front head of 

        boom is fit with motor-drive cross-slides of welding torch, and its end is fit with wire spool. Welding wire is

       joint to the torch by way of the wire linear on the welding arm. In this way, forming the welding support unit 

      of this weld manipulator for tank welding;

   2.  Welding system:

     Taking SAW (Submerged Arc Welding, which accounts for majority use in high precision tank welding machine)

     as example:

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

    2) 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: For internal welding inside small size cylinder part where people can not get access;

    3. Electric System

     1) Control system of this high efficiency welding column & boom is integral style, mainly composed of control

        cabinet, 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 tank welding machine is renowned ones, 

        such as SIEMENS, Schneider, etc.;

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