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.

Example 1:

when the stationary support bracket 11 is used for immobilization:

bridge pouring steel reinforcement cage supports and props tight frame, its major structure includes: the device comprises a ring frame 1, a central shaft 2 and a support frame 3; the ring array is equipped with the multiunit and props tight cylinder 4 on the ring frame 1, all sets up on every piston rod that props tight cylinder and indulges muscle bracing piece 5, it is equipped with perforation 6 on the muscle bracing piece 5 to indulge, the center of ring frame 1 is passed through the bearing and is connected with 2 rotations of center pin, the 2 other ends of center pin set up on support frame 3. The ring frame 1 is also provided with a backup plate 7 for aligning the tail ends of the longitudinal ribs. Supporting legs 8 are arranged at the tail ends of the two sides of the supporting frame 3, and the supporting legs 8 are fixed on the ground through foundation bolts.

Example 2:

when the slide support brace 12 is used in sliding connection with the slide mechanism:

bridge pouring steel reinforcement cage supports and props tight frame, its major structure includes: the device comprises a ring frame 1, a central shaft 2 and a support frame 3; the ring array is equipped with the multiunit and props tight cylinder 4 on the ring frame 1, all sets up on every piston rod that props tight cylinder and indulges muscle bracing piece 5, it is equipped with perforation 6 on the muscle bracing piece 5 to indulge, the center of ring frame 1 is passed through the bearing and is connected with 2 rotations of center pin, the 2 other ends of center pin set up on support frame 3. And the tail ends of the two sides of the support frame 3 are provided with slide blocks 9. And a balancing weight 10 is arranged on one side of the top of the support frame 3, which is far away from the ring frame 1.

The sliding mechanism and the screw nut transmission mechanism which are matched with the design for use have the following structural details:

as shown in the attached figure 1 of the specification, the sliding mechanism used in cooperation with the design comprises a sliding rail 13 and sliding blocks 9 which slidably support the tail ends of two sides of a supporting frame 3 of a tightening frame 12; slide rail 13 sets up in both sides, and the both ends of slide rail 13 support through supporting legs 8, and supporting legs 8 pass through rag bolt and fix subaerial.

The screw and nut transmission mechanism matched with the design comprises a servo motor 14, a transmission screw 15 and a driven nut 16, wherein the servo motor 14 is in transmission connection with the transmission screw 15, and the driven nut 16 is connected below the support frame 3 of the sliding support tightening frame 12.
