Description

Technical Field

[0001] This utility model relates to a tensioning drive device for reinforcing rings of steel cages, belonging to the field of steel cage production technology. Background Technology

[0002] A rebar cage welding workstation is a device that integrally processes and forms a rebar cage. For example, patent application number 202410401012.9 discloses a rebar cage welding workstation. In practice, workers manually install reinforcing rings on a roll welding machine, and then the roll welding machine automatically welds the main reinforcing bars to the reinforcing rings to form a rebar skeleton. After the rebar skeleton is welded, the roll welding machine releases the rebar skeleton and transfers it to one side of a rebar winding machine along a track via a moving component. Then, a lifting component abuts against and detaches the rebar skeleton from the moving component, and the moving component resets along the track. The rebar winding machine automatically performs winding welding on the rebar skeleton on the lifting component, while the roll welding machine restarts the welding of the reinforcing rings and main reinforcing bars.

[0003] The current steel cage welding technology is not comprehensive and has the following drawbacks: 1. The existing steel cage reinforcing ring tensioning drive device has a complicated structure, resulting in high production costs and difficult installation; 2. Each set of transmission rods does not use an independent reciprocating motion drive unit for transmission, which cannot guarantee the stability of transmission, shortens the service life, and increases the frequency of maintenance.
