The first electric telescopic rod 38 and the second electric telescopic rod 44 are electrically connected to the PLC controller 51 through wires, respectively.

The hydraulic cylinder 3 and the second hydraulic cylinder 24 are respectively connected with an external hydraulic station pipeline through a guide pipe.

The first electric telescopic rod 38 and the second electric telescopic rod 44 are both BXTL type electric push rods.

The working principle is as follows: when the steel bar clamping device is used, the PLC 51 is used for controlling the telescopic end of the second electric telescopic rod 44 to retract to the maximum degree, the telescopic end of the second electric telescopic rod 44 drives the square rod 45 to ascend in the process, the square rod 45 pushes the bottom of the clamping rod 41 through the second connecting rod 43 when ascending, the staggered angle of the two clamping rods 41 which are hinged to each other is increased, namely the tops of the two clamping rods 41 which are hinged to each other are opened, transverse steel bars can be placed on the two opened clamping rods 41 at the moment, and the telescopic end of the second electric telescopic rod 44 is controlled to extend to the maximum degree again after the transverse steel bars are placed, so that the tops of the two clamping rods 41 clamp the transverse steel bars.

The ring tendons are then hung on the arc-shaped support plates 31 on the L-shaped bars 30, and the threaded rods 34 are screwed by the handles 35, so that the arc-shaped clamping plates 33 are lowered to clamp the top of the ring tendons, so that the ring tendons are hung and fixed on the L-shaped bars 30, the position of the ring tendons on the L-shaped bars 30 can be adjusted in the front-rear direction along the direction of the square guide bars 27 by the square guide cylinders 28, so that the position of the ring tendons can be adjusted, after the position of the ring tendons is adjusted, the second locking bolts 29 are tightened to fix the square guide bars 27, and then the position of the ring tendons on the L-shaped bars 30 is adjusted up and down by the second hydraulic cylinders 24 so that the axis of the ring tendons is aligned with the axis of the arc-shaped plates 37 located at the center among the plurality of arc-shaped plates 37.

At this time, the telescopic end of the first hydraulic cylinder 3 is controlled to retract to the maximum extent, in the process, the transverse plate 4 rises along with the telescopic end of the first hydraulic cylinder 3, the transverse plate 4 pushes the arc-shaped pipes 8 through the first connecting rod 6 when rising, so that the two groups of arc-shaped pipes 8 respectively rotate around the hinged parts thereof as axes, in the rotating process of each group of two arc-shaped pipes 8, two arc-shaped plates 37 at two sides are respectively pulled through the steel wire rope 22, because each adjacent arc-shaped plate 37 is hinged through the hinge 54, when the telescopic end of the first hydraulic cylinder 3 retracts to the maximum extent, the plurality of arc-shaped plates 37 are combined into a completed ring under the pulling of the steel wire rope 22, the openings 48 are arranged on the two arc-shaped plates 3 at two sides, when the plurality of arc-shaped plates 37 are combined into the completed ring, the vertical rod of the L-shaped rod 30 is positioned in the opening 48, so that the reinforcing ring is wrapped by the combined rings of the plurality of arc-shaped plates 37 (as shown in fig. 5), along with the piece together of a plurality of arc 37, the also even distribution of a plurality of horizontal reinforcing bar is in the reinforcing bar ring outside simultaneously, the flexible end extension of first electric telescopic handle 38 of control through PLC controller 51 this moment, the flexible end extension of first electric telescopic handle 38 is pushed the horizontal reinforcing bar to the reinforcing bar ring direction through mounting panel 39 during, when the horizontal reinforcing bar is pasted the reinforcing bar ring, stop first electric telescopic handle 38 operation, can be so with the stable laminating of horizontal reinforcing bar to the reinforcing bar ring, staff alright get into the ring that closes the piece together by a plurality of arc 37 this moment, carry out weldment work to horizontal reinforcing bar and reinforcing bar ring and contact department. After all the contact points are welded, the telescopic end of the second electric telescopic rod 44 is controlled to retract to the maximum extent again, so that the two clamping rods 41 clamping the transverse steel bars are opened, then the telescopic end of the first hydraulic cylinder 3 is controlled to extend to the maximum extent, so that the plurality of arc-shaped plates 37 are reset (as shown in fig. 1), then the handles 35 are respectively screwed, so that the arc-shaped clamping plates 33 rise and do not clamp the steel bar rings, at the moment, the telescopic end of the second hydraulic cylinder 24 is controlled to extend, so that the L-shaped rod 30 descends, the welded steel bar cage falls onto the arc-shaped plates 37 along with the descending of the L-shaped rod 30, at the moment, the second locking bolt 29 is unscrewed, the L-shaped rod 30 can be moved to the side end and separated from the steel bar rings, and then the manufacturing process of the steel bar cage can be completed.

Because the setting of spring 21, spring 21 gives wire rope 22 pulling force all the time, also gives wire rope 22 buffer power simultaneously, avoids wire rope to pull hard and drags, and wire rope 22 can the flexible stable pulling arc 37 like this, ensures the steady amalgamation of closing of a plurality of arc 37. During the first lock nut 11 of unscrewing, alright in order to pass through handle 10 slip sleeve 9, can drive arc slider 15 synchronous motion when sleeve 9 slides, arc slider 15 slides in the arc pipe 8, can adjust the distance between arc slider 15 and first slider 20, when distance between arc slider 15 and the first slider 20 changes, spring 21's compressive strength can change, consequently, spring 21's elasticity can be adjusted, when moving arc slider 15 towards first slider 20 direction, spring 21 receives bigger compression, consequently, elasticity becomes strong, otherwise, when arc slider 15 moves in the opposite direction, the compression dynamics that spring 21 received diminishes, consequently, elasticity weak, consequently, when wire rope 22 does not pull arc 37, the position of regulation arc slider 15 that can be nimble, ensure that wire rope 22 can pull arc 37.

The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed.
