The height of the first fixed beam 3 is the same as that of the second fixed beam 4. The advantage is that the first fixed beam 3 and the second fixed beam 4 are provided. During installation, first lock and connect the first fixed beam 3 and the fixed ear 2 with bolts, and then lock and connect the second fixed beam 4 and the fixed ear 2 with bolts. At this time, the second fixed beam 4 and the first fixed beam 3 are adaptively combined, and the first fixed beam 3 and the second fixed beam 4 are locked and fixed with bolts, with good fixing effect and uniform force.

The advantage is that when the wall-attached limit hoop is used, first slide and adjust the adjusting pipe 510 and the telescopic pipe 512 of the front and rear end limit components 5 of the standard section 1 to reach an appropriate total length. The distance between the telescopic pipe 512 and the wall needs to be less than the width of the triangular cross-section of the inclined seat 502. Pass bolts through the adjusting hole 511 and the telescopic hole 513 to lock the adjusting pipe 510 and the telescopic pipe 512. After aligning the telescopic pipe 512 with the installation groove 602, lock and connect the plate body 601 and the telescopic pipe 512 with bolts. Start the motor 508 to drive the worm gear 507 to rotate. The worm gear 507 drives the meshed worm wheel 506 to rotate, and the screw rod 504 rotates accordingly. The screw rod 504 rotates to drive the thread-connected slider 509 to move along the slide rod 505 and the slide rail 514. While the telescopic pipe 512 and the reinforcement plate 6 move downward, they expand outward until the reinforcement plate 6 contacts the wall, tension and fix the standard section 1 to the wall.

Then, use the same method to assemble the limit components 5 at the left and right ends of the standard section 1 with the reinforcement plate 6, and tension and fix the left and right sides of the standard section 1 to the wall. The screw rod 504 is inclined. After the limit component 5 is tensioned and fixed, the standard section 1 receives a horizontal force and an upward component force, which has a supporting effect and makes the standard section 1 more stable. The worm wheel 506, the worm gear 507, and the screw rod 504 all have the self-locking and anti-return characteristics and can be locked after adjustment, with high stability. Moreover, the worm wheel 506, the worm gear 507, and the screw rod 504 all have the function of amplifying torque, reducing the requirements for the motor 508 and the cost.

[0037] Working principle: When the wall-attached limit hoop is in use, first slide and adjust the adjusting pipe 510 and the telescopic pipe 512 of the front and rear end limit components 5 of the standard section 1 to reach an appropriate total length. The distance between the telescopic pipe 512 and the wall needs to be less than the width of the triangular cross-section of the inclined seat 502. Use bolts to pass through the adjustment hole 511 and the telescopic hole 513 to lock the adjusting pipe 510 and the telescopic pipe 512. After aligning the telescopic pipe 512 with the installation groove 602, lock and connect the plate body 601 and the telescopic pipe 512 with bolts. Start the motor 508 to drive the worm 507 to rotate. The worm 507 drives the engaged worm wheel 506 to rotate, and the screw 504 rotates accordingly. The rotation of the screw 504 drives the threaded slider 509 to move along the slide rod 505 and the slide rail 514. While the telescopic pipe 512 and the reinforcement plate 6 move downward, they expand outward until the reinforcement plate 6 contacts the wall, tensioning and fixing the standard section 1 to the wall. Use anchor bolts to fixedly connect the reinforcement plate 6 to the wall. Then, assemble the limit components 5 at the left and right ends of the standard section 1 and the reinforcement plate 6 in the same way, tensioning and fixing the left and right sides of the standard section 1 to the wall. The screw 504 is inclined. After the limit component 5 is tensioned and fixed, the standard section 1 is subjected to a horizontal force and an upward component force, having a supporting effect and making the standard section 1 more stable. The worm wheel 506, the worm 507, and the screw 504 all have the characteristics of self-locking and anti-return. They can be locked after the adjustment is completed, with high stability. Moreover, the worm wheel 506, the worm 507, and the screw 504 all have the effect of amplifying torque, reducing the requirements for the motor 508 and the cost. The tensioning operation can be completed using the motor 508, saving manpower.
