[0002] Steel cages, consisting of stirrups and longitudinal bars, are the backbone of a building and play a major load-bearing role. They are used in large quantities during construction. Currently, some standard steel cages can be manufactured using automated equipment using wire tying or welding processes.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The steel cage conveying mechanism and the steel cage lifting mechanism of the present invention can both move on the guide rails to achieve automatic adjustment of the spacing, which can meet various flexible and personalized needs of steel cage operations of various specifications on the production line. The steel cage conveying mechanism can realize the automation of the loading and unloading processes, and the steel cage lifting mechanism can lift the steel cage to easily achieve the installation of stirrups, solving the problems of inconvenient stirrup installation and the need to lift the long-sized frame-type non-fully rigid steel cage over a short distance.

[0017] 3. The horizontal guide assembly and vertical guide assembly of the present invention can be modularized and can be set up in two or more groups according to the volume and mass of the lift, which is flexible and diverse. Thus, the length of the parallelogram support surface can be adjusted arbitrarily without affecting the consistency of the movement of the support surface. In addition, the vertical guide assembly limits the support plate to only up and down movement, not horizontal movement.

Each group of the horizontal guide assemblies includes a third slider 212 and a third slide rail 210 connected to the base. The direction of the third slide rail is perpendicular to the direction of the guide rail. The third slider is provided with a connecting plate 202. Several connecting plates are connected in series through joints 211, pins 214 and several transmission connecting rods 204 to form a whole. Several of the transmission connecting rods are driven by a cylinder 205. There is at least one connecting bar 202 between the support plate and the connecting plate. 6. One end of the connecting strip is movably connected to the support plate through a first shaft sleeve 215 and a first hinge pin 216. The first hinge pin and the first shaft sleeve keep rotating relative to each other. The other end of the connecting strip is movably connected to the connecting plate through a second shaft sleeve 217 and a second hinge pin 218. The second hinge pin and the second shaft sleeve keep rotating relative to each other. The base is provided with an array of vertical guide components 222 connected to the support plate for limiting the up and down movement of the support plate.

The support plate is connected to the fourth The slider is slidably connected to the fourth slide rail, and a support block 207 connected to the support plate is provided on the guide plate. Any two connecting strips and the support plate and the base are hinged to form a parallelogram. The simple parallelogram principle is used to connect the transmission connecting rod to realize linkage, and then cooperate with the vertical guide assembly to realize the lifting of the steel cage. The steel cage lifting mechanism has only one cylinder power source to realize the lifting of long-distance objects. It is a labor-saving mechanism. The horizontal guide assembly and the vertical guide assembly can be modularized. Two or more groups can be set according to the volume and mass of the lifted steel cage. It is flexible and diverse.

[0034] During the implementation process, one rebar cage lifting mechanism is stationary, while the other rebar cage lifting mechanism and two rebar cage conveying mechanisms adjust their positions according to the different specifications of the rebar cages. Both rebar cage lifting mechanisms transmit power via a second motor driving a second transmission shaft, which drives two second reducers to drive the corresponding second gears along the rack, thereby driving the corresponding second sliders to slide on the guide rails until they stop at a position suitable for the rebar cage specifications. The rebar cage conveying mechanism to be moved transmits power via a first motor driving a first transmission shaft, which drives two first reducers to drive the corresponding first gears along the rack, thereby driving the corresponding first sliders to slide on the guide rails until the spacing between the two rebar cage conveying mechanisms meets the rebar cage specifications and stops. When the rebar cage is ready to enter the production line, the chain plate line assembly in the rebar cage conveying mechanism begins to rotate, and the bottom of the stirrups making up the rebar cage contacts the transmission chain plate, which drives it forward. When the bottom of the stirrups on the rebar cage enters the lifting position, the transmission chain plate stops conveying. When the cylinder is actuated, force is transmitted through the drive connecting rod, simultaneously acting on the connecting bar connected to the support plate, gradually raising the support plate along the horizontal and vertical guide assemblies, lifting the rebar cage off the supporting drive chain plate without affecting workers' installation of stirrups. Finally, the connecting bar reaches a vertical position, marking the dead center of the mechanism. After the stirrups are installed, the support plate drops, the rebar cage contacts the drive chain plate, and a third drive device drives the rebar cage conveyor mechanism to unload or transport the rebar cage to the next workstation.
