[0017] 2. The present invention is connected between the winding wheel and the Z-shaped support base through a steel wire rope, so that when the support base plate rises, it can drive the steel wire rope to pull the Z-shaped support base to move inward, so that the alignment bracket can squeeze the U-shaped stirrup to contact the steel bar, and the movable square rod can be extended and retracted up and down inside the Z-shaped support base, so that the alignment bracket can be easily lifted upward to complete the adaptation work of the alignment bracket.

[0044] The U-shaped stirrup 3 is placed on the top of the supporting base plate 8 and inside the alignment bracket 28, the L-shaped air cylinder 11 is symmetrically fixedly installed on both sides of the top of the main frame 34, the first rack 13 is meshed with the top of the side end of the second gear 41, the second rack 17 is meshed with the first gear 22, the extension base 23 is symmetrically fixedly installed on the top of both sides of the main frame 34, the bottom end of the Z-shaped support base 26 is slidably inserted into the top of the extension guide rail 36, the third rack 33 is meshed with the bottom of the side end of the second gear 41, the displacement bracket 14 is slidably inserted into the inside of both ends of the two sides of the main frame 34, both ends and both sides of the main frame 34 are provided with through holes adapted to the displacement bracket 14, the first arc-shaped card plate 15 is aligned with the steel bar 4, the bottom center of the alignment gasket 35 is provided with a square hole, and the alignment gasket 35 is vertically aligned with the superimposed vertical rod 39, the interior of the L-shaped air cylinder 11 is set in a hollow state, and a closed cavity is formed between the first piston rod 10, the L-shaped air cylinder 11 and the second piston rod 12, the tops of the closing card plate 7 are all inclined at 45°, the support bottom plate 8 is horizontally aligned with the alignment card frame 28, the bottom end of the Z-shaped support base 26 is fixedly installed with a card key, and the top of the extension guide rail 36 is provided with a card slot, the side end of the second return spring 38 away from the limiting side plate 37 is connected to the end of the Z-shaped support base 26 away from the wire rope 25, another displacement card frame 14 is fixedly installed between the support cross plate 32 and the second arc card plate 29, and the side end of the first alignment key 30 close to the second arc card plate 29 and the side end of the second alignment key 44 close to the second gear 41 are both inclined at 45°.

[0045] When implementing this embodiment, when in use, when it is necessary to install U-shaped stirrups 3 on the steel bars 4, the base structure 1 can be placed as a whole between the multiple steel bars 4, and then the U-shaped stirrups 3 are squeezed through the two closed clamps 7. The top of the closed clamp 7 is inclined at 45 degrees, so that the U-shaped stirrups 3 can pass through the closed clamp 7 and enter the interior of the supporting bottom plate 8. Subsequently, the rear end of the U-shaped stirrup 3 is placed inside the top of the alignment clamp 28. At the same time, the handle 31 can be pulled toward the end away from the third rack 33, so that the supporting cross plate 32 and the second arc clamp 29 can be driven to move simultaneously until the second arc clamp 29 contacts the steel bars 4 at both ends of the concrete base 2 and reaches the extreme pressure. At the same time, when the second arc-shaped clamping plate 29 moves to the limit position, the first alignment key 30 can be driven to completely pass through the second alignment key 44. Prior to this, the side end of the second alignment key 44 close to the second gear 41 and the side end of the first alignment key 30 close to the second arc-shaped clamping plate 29 are both inclined at 45°, so that the smoothness of the first alignment key 30 passing through the second alignment key 44 can be improved. Subsequently, when the first alignment key 30 completely passes through the second alignment key 44, the elasticity of the third reset spring 43 will drive the second alignment key 44 to reset, so that the second alignment key 44 can prevent the first alignment key 30 from resetting, thereby completing the positioning of the steel bars 4 at both ends of the top of the concrete base 2;

[0046] When the second arc-shaped clamping plate 29 moves, the third rack 33 can also be driven to pass around the periphery of the second gear 41, so that the second gear 41 can be driven to rotate. The first rack 13 is meshed with the outer top of the second gear 41, so that when the second gear 41 rotates, it can drive the displacement clamping frame 14 and the first arc-shaped clamping plate 15 to move toward the outside of the main frame 34 at the same time. Therefore, when the second arc-shaped clamping plate 29 contacts the steel bars 4 at both ends of the top of the concrete base 2, the first arc-shaped clamping plate 15 can also contact the steel bars 4 on both sides of the top of the concrete base 2, completing the basic positioning work of the main frame 34;

[0047] At the same time, when the first arc-shaped card plate 15 moves toward the outside of the main frame 34, it can drive the synchronous connecting rod 18 to move at the same time, so that the second piston rod 12 can move toward the inside of the L-shaped air cylinder 11, causing the first piston rod 10 to drive the supporting base plate 8 to move upward at the same time. At this time, when the supporting base plate 8 moves upward, it can simultaneously drive the second rack 17 to pass through the first gear 22, so that the first gear 22 can drive the winding wheel 24 to rotate at the same time. When the winding wheel 24 rotates, the wire rope 25 can be pulled to drive the Z-shaped supporting base frame 26 to one end close to the winding wheel 24. The U-shaped stirrup 3 and the steel bar 4 are moved upwards, so that the alignment bracket 28 and the support base plate 8 can support the U-shaped stirrup 3 to move upwards at the same time. Afterwards, when the support base plate 8 and the alignment bracket 28 rise to the limit position, the alignment bracket 28 can be driven to squeeze the U-shaped stirrup 3 and the steel bar 4 to tighten, so as to prevent the U-shaped stirrup 3 from tilting and falling. At the same time, the key at the bottom end of the Z-shaped support base 26 slides in the groove inside the top end of the extension guide rail 36, so that the Z-shaped support base 26 can be supported to move in a straight line. At the same time, when the support base plate 8 rises, the U-shaped stirrup 3 and the alignment bracket can also be driven. 28 moves upward at the same time, so that the supporting bottom plate 8 and the alignment bracket 28 can support the U-shaped stirrup 3 at a specified height to perform limiting work. Subsequently, when the base mechanism 1 of the base is installed, the new base mechanism 1 can be stacked upward again to prevent it, and the square hole at the bottom end of the alignment gasket 35 is slidably sleeved on the stacking vertical rod 39, so that the base mechanism 1 can be supported to be stacked and placed to complete the work. When the device is in use, the base mechanism 1 can be stacked and placed, so that the U-shaped stirrup 3 can be supported to contact and tighten with the steel bar 4 at a fixed height, and through the third rack 33 The first rack 13 is respectively meshed with the second gear 41, so that when the second arc-shaped clamping plate 29 moves, it can simultaneously drive the first arc-shaped clamping plate 15 to contact the steel bar 4, thereby completing the base positioning work of the main frame 34, and while the second arc-shaped clamping plate 29 and the first arc-shaped clamping plate 15 move, it can also drive the supporting base plate 8 and the alignment clamping frame 28 to be lifted upward at the same time, so that the supporting base plate 8 and the alignment clamping frame 28 can support the U-shaped stirrup 3 to contact and tighten with the steel bar 4 at a specified height, thereby completing the work of installing the U-shaped stirrup 3 on the steel bar 4 without binding.

[0048] Example 2

[0049] On the basis of Example 1, Fig.10 As shown, the stacked vertical rod 39 also includes an extension rod 45, a support block 46 and a positioning bolt 47. The extension rod 45 is slidably inserted inside the top end of the stacked vertical rod 39, the support block 46 is equidistantly fixed inside the front end of the stacked vertical rod 39, and the positioning bolt 47 is threadedly inserted into the support block 46 and the extension rod 45.

[0050] When implementing this embodiment, when it is necessary to adjust the distance between the base mechanism 1 and the base mechanism 1, the extension rod 45 can be moved upward at the inner center of the stacked vertical rod 39 until the threaded hole on the extension rod 45 is aligned with the support block 46 at the specified height, and the positioning bolt 47 can be screwed through the support block 46 and into the threaded hole inside the extension rod 45, so that the extension rod 45 can be limited to perform supporting work at the specified height. Subsequently, the alignment gasket 35 in another base mechanism 1 can be placed on the top of the extension rod 45 to complete the work of controlling the distance between the base mechanism 1 and the base mechanism 1, and the gap between the support blocks 46 and the support blocks 46 is 1 cm, so that the moving height of the extension rod 45 can be accurately controlled to complete the work.
