[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1-4 The present invention provides a technical solution: an adjustable steel cage storage rack, comprising a steel cage 1 and a base 2, wherein a groove 11 is provided on the top of the base 2 along the length direction, and the groove 11 is centrally arranged in the base 2. A bidirectional screw 4 is rotatably arranged in the groove 11, and a movable block 14 is symmetrically threadedly connected at the positive and negative threads of the bidirectional screw 4. The movable block 14 is slidably connected to the groove 11, and two movable blocks 14 are symmetrically arranged on the two movable blocks 14. The two arc support frames 3 can be moved closer or farther away by rotating the bidirectional screw 4. The arc support frames 3 are supported on both sides of the bottom of the steel cage 1 along the length direction of the steel cage 1, and the side edges of the arc support frames 3 in contact with the steel cage 1 are arc edges that fit the steel cage 1. A cavity 13 is provided in one of the arc support frames 3, and a fastening belt 6 is placed in the cavity 13. The free end of the fastening belt 6 passes through the open slot 5 at the top of the arc support frame 3 and is connected to the other arc support frame 3. The steel cage 1 is fixed on the arc-shaped support frame 3 by tightening the belt 6 to prevent the steel cage 1 from rolling down and causing danger.

[0023] A rotating shaft 12 is disposed within the cavity 13, perpendicular to the length of the base 2. One end of the rotating shaft 12 passes through the arc-shaped support frame 3 and is fixedly connected to a rotating handle 10. The other end of the rotating shaft 12 is rotatably connected to the side wall of the cavity 13 via a bearing. The side wall of the rotating shaft 12 is connected to the fixed end of the tightening belt 6. By rotating the rotating handle 10, the pulled tightening belt 6 can be retracted into the interior of the arc-shaped support frame 3.

[0024] One end of the bidirectional screw rod 4 passes through the groove 10 and is fixedly connected to the hand wheel 9. The bidirectional screw rod 4 is a trapezoidal screw rod capable of self-locking.

[0025] The free end of the fastening belt 6 is provided with two draw hooks 7, and the top of the arc-shaped support frame 3 where the fastening belt 6 is not installed is provided with two fixed pull rings 8. The positions of the draw hooks 7 and the fixed pull rings 8 correspond to each other and can be tied to each other.

[0026] A screw 104 passes through one end of the rotating handle 10, and the screw 104 is threadedly connected to the rotating handle 10. A rubber pad 103 is installed at the lower end of the screw 102, and the rubber pad 103 can abut against the side wall of the arc-shaped support frame 3. A knob 102 is provided at the upper end of the screw 102.

[0027] Working Principle: First, adjust the distance between the two arc-shaped support frames 4 according to the diameter of the rebar cage 1 to be placed. Turning the handwheel 9 rotates the bidirectional screw 4 in the groove 11, which in turn drives the movable blocks 14 symmetrically connected to the bidirectional screw 4 closer or farther away, thereby adjusting the two symmetrically arranged arc-shaped support frames 3 to the appropriate distance so that the rebar cage 1 to be placed can fit snugly on the arc-shaped support frames 3. Repeat the above steps to place the two adjusted storage devices according to the length of the rebar cage 1, and then hoist the rebar cage 1 onto the two storage devices.

[0028] After the reinforcement cage 1 is placed, the fastening belt 6 set in the arc-shaped support frame 3 is pulled out, and the two hooks 7 at the free end of the fastening belt 6 are tied to the fixed pull ring 8 on the other arc-shaped support frame 3 by passing around the upper surface of the reinforcement cage 1. By turning the knob 102, the rubber pad 103 is pressed against the side wall of the arc-shaped support frame 3, increasing the friction between the two, thereby locking the rotating handle 10. The fastening belt 6 fixes the reinforcement cage 1 to the arc-shaped support frame 3, preventing the reinforcement cage 1 from rolling away and causing danger.
