Detailed Description

The present invention will be further described with reference to the following specific examples. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that various changes or modifications of the present invention may be made by those skilled in the art after reading the teachings of the present invention, and these equivalents also fall within the scope defined in the present application.

Bridge perfusion reinforcement cage welding appurtenance, major structure includes fixed stay assembly 1, slip support assembly 2 and positioner.

The structural overview analysis of the fixed support assembly 1 and the sliding support assembly 2:

the fixed support assembly 1 and the sliding support assembly 2 both comprise a ring frame 3, a central shaft 4 and a support frame 5; the annular array is equipped with the multiunit and props tight cylinder 13 on the ring frame 3, all sets up on every piston rod that props tight cylinder and indulges muscle bracing piece 6, indulges to be equipped with on the muscle bracing piece 6 and perforates 7, and the center of ring frame 3 is passed through the bearing and is connected with the rotation of center pin 4, and the 4 other ends of center pin set up on support frame 5.

The fixed support assembly 1 and the sliding support assembly 2 have different structures in that:

the ring frame 3 of the first fixed supporting assembly 1 is also provided with a backup plate 14 for aligning the tail ends of the longitudinal ribs; the ring frame 3 of the sliding support assembly 2 is not provided with a backup plate 14.

Secondly, supporting feet 15 are arranged at the tail ends of two sides of a supporting frame 5 of the fixed supporting assembly 1, and the supporting feet 15 are fixed on the ground through foundation bolts; the slide blocks 8 are arranged at the tail ends of two sides of the support frame 5 of the sliding support assembly 2, the driven screw 12 is arranged below the middle part, and the balancing weight 17 is arranged on one side, far away from the ring frame 3, of the top of the support frame 5.

Overview and analysis of the positioning device structure:

the position adjusting device comprises a slide rail 9, a servo motor 10 and a screw rod and nut transmission mechanism. The slide rails 9 are arranged on two sides, two ends of each slide rail 9 are supported by supporting legs 15, the supporting legs 15 are fixed on the ground through foundation bolts, and the slide blocks 8 on the support frames 5 of the slide support assembly 2 are connected with the slide rails 9 in a sliding mode; the servo motor 10 drives a screw rod and nut transmission mechanism, the screw rod and nut transmission mechanism comprises a transmission screw rod 11 and a driven screw nut 12, two sides of the transmission screw rod 11 are supported by bearings 16 with seats, and the driven screw nut 12 is positioned below the support frame 5 of the sliding support assembly 2 and is in transmission connection with the transmission screw rod 11; the rotation of the servo motor 10 drives the transmission screw 11 to rotate, and further drives the driven screw 12 and the sliding support assembly 2 to translate along the direction of the slide rail 9.

The use method of the device is analyzed by combining the attached figure 4 of the specification:

as shown in fig. 4, the position of the sliding support assembly 2 is adjusted by the servo motor 10 and the screw nut transmission mechanism to be suitable for the length of the longitudinal bar. In indulging perforation 7 on the muscle bracing piece 6 with many corresponding installations in both sides of indulging of muscle, and the muscle end and the backup plate 14 contact of indulging of one side to make the muscle end of indulging of one side align, the ring muscle cover of certain quantity is in the muscle outside of indulging that the annular array set up, it is close to the support frame 5 that the regulation slip support assembly 2 can not pass the regulation slip support assembly 2 that indulges the muscle end of indulging of adjustment slip support assembly 2 one side to need notice, if pass the support frame 5 of adjustment slip support assembly 2, so support frame 5 will restrict the ring frame 3 that is provided with the.

Then start multiunit simultaneously and prop up tight cylinder 13, prop up the piston rod of tight cylinder 13 and slowly extend to will indulge the muscle and expand outward along radial direction, until indulging the muscle and the ring muscle internal surface and be about to contact and not contact.

Then after adjusting the welding position of the ring rib on the longitudinal rib, simultaneously starting the plurality of groups of tightening cylinders 13 again, and extending the piston rods of the tightening cylinders 13, so that the longitudinal rib is further expanded along the radial direction, and the longitudinal rib is in contact with the inner surface of the ring rib to be tightened.
