[0021] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0023] like Figure 1-4 As shown, a bridge pier column steel bar positioning device includes a plurality of insert tubes 1, which are used to be sleeved on the steel bars, and are rotatably connected to a connecting ring 2 at the bottom edge of the outer wall of the insert tube 1, the surface of the connecting ring 2 is hollowed out, and a clamping block 9 is arranged between two adjacent connecting rings 2, and a column 15 is threadedly connected to the clamping block 9 and inserted into the hollow part of the clamping block 9. A plurality of clamping blocks 6 distributed in a ring array and arranged parallel to the center line of the insert tube 1 are arranged in the insert tube 1, and the plurality of clamping blocks 6 move relative to the center line of the insert tube 1 at the same time and are used to clamp the surface of the steel bars.

[0024] In this plan:

[0025] When this solution is used to locate the positions of two adjacent steel bars after the steel bars are tied:

[0026] According to the size of the steel bars used and the spacing X between two adjacent steel bars, adjust the distance between several clamping blocks 6 and the center line of the insert tube 1, cut the block 9 that is suitable for the length of the spacing X, and thread the plug column 15 on both sides of the block 9. Put one of the insert tubes 1 on one of the steel bars, and put the other insert tube 1 on the adjacent steel bar. Rotate and adjust the connecting ring 2 on the insert tube 1 until the hollow parts on the two adjacent connecting rings 2 are symmetrically distributed, and then place the block 9 between the two insert tubes 1. When the plug column 15 on the block 9 can be inserted into the hollow parts of the connecting rings 2 on the two connected insert tubes 1, it means that the positions of the steel bars mounted on the two adjacent insert tubes 1 are aligned.

[0027] The clamp block 6 is fixedly connected to a screw rod 5 on the side facing away from the center line of the insert tube 1 and symmetrically fixedly connected to two guide rods 7 penetrating the wall of the insert tube 1 . The outer wall of the insert tube 1 is rotatably connected to a threaded tube 14 threadedly connected to the screw rod 5 .

[0028] An upper worm gear ring 13 is fixedly connected to the outer wall end surface of the threaded cylinder 14 , and an upper worm 12 meshingly connected to the upper worm gear ring 13 is rotatably connected to the outer wall of the insert cylinder 1 .

[0029] A universal shaft 4 is connected between adjacent end surfaces of two adjacent upper worm gears 12 .

[0030] By rotating one of the upper worm gears 12, under the connection and transmission action of the universal joint 4, several upper worm gears 12 can rotate simultaneously, and then all the upper worm wheel rings 13 on the outer wall of the insert tube 1 drive the corresponding threaded tube 14 to rotate, and the screw 5 in the threaded tube 14 cannot rotate because the guide rod 7 on the clamping block 6 restricts the clamping block 6, so that the screw 5 fixedly connected to the clamping block 6 will not rotate. Therefore, when the threaded tube 14 rotates, the internal screw 5 can drive the clamping block 6 to move relative to the center line direction of the insert tube 1, and all the clamping blocks 6 in the insert tube 1 can move simultaneously.

[0031] A plurality of connecting tubes 10 distributed in a circular array are fixedly connected to the bottom edge of the outer tube wall of the inserting tube 1 , and drill rods 11 are inserted into the connecting tubes 10 .

[0032] Specifically, when the insert tube 1 is sleeved on the steel bar, the drill rod 11 can contact the concrete at the bottom of the steel bar. Therefore, by judging the length of the drill rods 11 extending out of the connecting tube 10, it is judged whether the insert tube 1 is tilted, that is, the inclination of the steel bar in the insert tube 1 is judged.

[0033] A lower worm wheel ring 3 is fixedly connected to the upper surface of the connecting ring 2 , and a lower worm 8 meshing with the lower worm wheel ring 3 is rotatably connected to the bottom edge of the outer wall of the insert cylinder 1 .

[0034] The lower worm gear ring 3 is located on a side of the connecting cylinder 10 away from the insert cylinder 1 .

[0035] In this plan:

[0036] By rotating the lower worm 8, the meshing lower worm wheel ring 3 can drive the connecting ring 2 to rotate, thereby adjusting the angle of the hollow part on the connecting ring 2 so that the hollow parts on two adjacent connecting rings 2 are symmetrically arranged.

[0037] Working principle: According to the size of the steel bar, the upper worm 12 is rotated, and several upper worms 12 are rotated simultaneously through the universal joint 4, so that the meshing upper worm wheel ring 13 drives the corresponding threaded tube 14 to rotate. When the threaded tube 14 rotates, the internal screw 5 drives the clamping block 6 to move relative to the center line direction of the inserted tube 1, and all the clamping blocks 6 in the inserted tube 1 are moved simultaneously to a distance from the center line of the inserted tube 1 equal to the radius of the steel bar. The inserted tube 1 is sleeved on the steel bar, and the lower worm 8 is rotated. The meshing lower worm wheel ring 3 can drive the connecting ring 2 to rotate, so as to adjust the angle of the hollow part on the connecting ring 2, and put the clamping block 9 between the two adjacent inserted tubes 1. The relative position of the two adjacent steel bars is determined by judging whether the column 15 is successfully inserted into the hollow part on the connecting ring 2.

[0038] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
