Overview of the Automated Welding Workstation for the Construction Elevator Frame

The construction elevator frame (hoist cage frame) is the core load-bearing and protective structure of the construction elevator. It is an overall rectangular box-type high-strength steel structure, mainly composed of main beams, side frames, upper and lower end beams, reinforcing partitions, guide rail connection plates, hinge support seats and other components welded together.

The entire production line adopts a multi-station assembly line layout, with segmented processes and coordinated operations.
 

The production line adopts a streamlined layout. The equipment has a high degree of integration and strong automation. The core equipment consists of the following:

•The workstation is equipped with a multi-specification construction elevator cage frame. Through program switching and tool adjustment, it can be compatible with flexible production of different height and tonnage frame products.
• The workstation adopts an integrated precision processing rigid reference fixture, which effectively controls the shrinkage deformation, distortion and diagonal deviation during the welding process.
• The dedicated positioning machine for equipment can enable the multi-angle flipping and fine adjustment of the frame components.
•The workstation enables the entire welding process of the construction elevator frame to be carried out automatically and in a standardized manner, with uniform and controllable welding process parameters.

Overview of the Automated Welding Workstation for Partition Boards

The reinforcement partition of the construction elevator frame is the core strengthening and torsional-bearing component within the elevator cage frame. It is mainly distributed inside the main beams, side frames and end beams of the elevator cage.

  • 1. Integrated Assembly and Welding Fixture

    The workstation is compatible with the welding production of various thicknesses and different arrangement specifications of reinforcement partitions.
  • 2. Improve production efficiency

    The production line can achieve simultaneous production of two pieces, significantly increasing the production cycle, reducing manual intervention by over 60%, and lowering labor costs and rework expenses.
  • 3. Flexible Design

    It can automatically detect the errors of the workpiece group alignment, real-time correct the welding trajectory, and precisely control the penetration depth, weld width and weld formation.
  • 4. Lean Control of Welding Cycle Time

    The workstation completely replaces the manual multi-point repetitive welding operations, and the welding actions are standardized.

Overview of the Automated Welding Workstation for the Main Beam of the Frame

The main beam has the following technical characteristics: large length, long longitudinal continuous welds, concentrated welding heat input, and high requirements for linearity accuracy.

  • Core advantages of the process

    The workstation is equipped with a customized rigid positioning fixture specifically for the long main beam, and uses an overall precision machined reference platform.
  • Robotic Welding Station

    The dedicated long-stroke offset equipment is provided to enable the main beam workpiece to rotate smoothly in all directions within 360 degrees and to adjust its position at multiple angles.
  • Improve production efficiency

    Long weld seams, corner weld seams and lap weld seams are all adjusted to the optimal ship shape weld configuration.
  • Flexible Platform Design

    Adopting a low-stress, stable heat input multi-layer multi-pass welding process suitable for long beam components
