[ detailed description ] embodiments
Referring to the attached drawings 1-2 of the specification, the present invention relates to a hoisting and positioning device for a bored concrete pile reinforcement cage, which is used for hoisting and positioning a reinforcement cage 10, and comprises a hoop 1, a hoop bolt 2, an eye bolt 3, a connecting bolt 4, a stainless steel basket 5, a post bolt 6, a steel casing 7, and the like.
The hoop 1 is provided with two symmetrically arranged hoops and encloses the reinforcement cage 10. The two hoops 1 have the same structure. The inside of staple bolt 1 is equipped with a plurality of couples 11, and steel reinforcement cage 10 hangs on couple 11. In the present embodiment, the number of the hooks 11 is specifically 4. And the middle part of the outer side of the hoop 1 is provided with a mounting seat 12.
The anchor ear bolts 2 are screwed on two sides of the anchor ear 1 and connect the two anchor ears 1 together.
One end of the lifting ring bolt 3 is welded with a lifting ring 31, and the lifting ring 31 is sleeved on the hoop bolt 2 and is positioned between the two hoops 1.
The connecting bolt 4 is mounted on the mounting seat 12 and penetrates out of the mounting seat 12. The lifting eye bolts 3 and the connecting bolts 4 are arranged at 90-degree included angles.
The stainless steel flower basket 5 is respectively connected with the suspension bolt 3 and the connecting bolt 4 in a threaded manner.
One end of the ejector rod bolt 6 is in threaded connection with the stainless steel flower basket 5, and the other end of the ejector rod bolt abuts against the steel casing 7. Specifically, four U-shaped grooves 71 are welded on the inner wall of the steel casing 7; the end part of the ejector rod bolt 6 is provided with an ejector head 61, and the ejector head 61 abuts against the U-shaped groove 71.
Further, the turning directions of the threads on the ejector rod bolt 6 and the threads on the eye bolt 3 and the connecting bolt 4 are opposite, so that when the stainless steel flower basket 5 is rotated, the ejector rod bolt 6 on the same stainless steel flower basket 5 and the eye bolt 3 and the connecting bolt 4 move towards or away from each other.
The utility model discloses a hoist and mount and positioner's of bored concrete pile steel reinforcement cage design principle as follows: sleeving the hoop 1 outside the reinforcement cage 10, and hooking a reinforcement stirrup of the reinforcement cage 10 by using a hook 11 on the inner side of the hoop 1; connecting two anchor ears 1 by using anchor ear bolts 2; a crane (not shown) hooks the anchor ear bolt 2 and lifts the anchor ear 1 and the reinforcement cage 10, so that the reinforcement cage 10 is hoisted into the steel casing 7. And adopt the hoist and mount steel reinforcement cage 10 of staple bolt 1 form, make steel reinforcement cage 10 atress even, can effectively avoid steel reinforcement cage 10 to take place to warp at the hoist and mount process.
When the position of the reinforcement cage 10 needs to be adjusted, the stainless steel flower basket 5 is rotated, so that the distance between the ejector rod bolt 6 and the lifting eye bolt 3 and the distance between the ejector rod bolt 4 and the lifting eye bolt 3 are adjusted, and the positions of the hoop 1 and the reinforcement cage 10 in the steel casing 7 are adjusted; and simultaneously, the utility model discloses set up 4 stainless steel flower baskets 5, consequently can a plurality of position adjustment steel reinforcement cage 10's position to accurate positioning steel reinforcement cage 10, and convenient operation.
The above embodiments are merely preferred embodiments of the present disclosure, which are not intended to limit the present disclosure, and any modifications, equivalents, improvements and the like, which are within the spirit and principle of the present disclosure, should be included in the scope of the present disclosure.
