[0023] The first fixing blocks 406 are fixedly connected to the symmetrical positions of the arc surface of the inner wall of the limiting groove 3; both ends of the No. 1 limiting block 1 and the No. 2 limiting block 2 are provided with placement grooves 407; a limiting hole 408 is provided on the bottom end surface of the inner wall of the placement groove 407; the bottom of the limiting hole 408 passes through the body of the No. 1 limiting block 1 and the No. 2 limiting block 2; positioning blocks 409 are slidably installed inside the placement groove 407; positioning rods 410 are fixedly connected between the positioning blocks 409; connecting blocks 411 are fixedly connected to both ends of the positioning blocks 409; a card slot 412 is provided around the connecting block 411 on one side of the positioning block 409; the end of the connecting block 411 on the other side of the positioning block 409 is fixedly connected with Iron wire 413; when the iron wire 413 acts, the moving end of the iron wire 413 is wound inside the card slot 412; the distance between the vertical surfaces on both sides of the connecting block 411 is the same as the width of the first limit block 1; the second fixing block 414 is symmetrically fixed on the top arc surface of the positioning block 409; the vertical cross-sectional dimension of the second fixing block 414 is the same as the vertical cross-sectional dimension of the first fixing block 406; when the positioning block 409 is located inside the placement groove 407, the structural surface where the inner wall arc surface of the positioning block 409 is located coincides with the structural surface where the inner wall arc surface of the placement groove 407 is located; the action section of the second fixing block 414 coincides with the action section of the first fixing block 406;

[0024] During operation, during the concrete pouring process, the concrete cooling pipe is required to control the temperature of the concrete. When the cooling pipe is installed, a positioning device is required to cooperate with the operation. When the existing concrete cooling pipe positioning device is used, it can only position and fix the cooling pipe at a specified position, and there is still a certain error in the distance between the pipe bodies, which makes the concrete cooling operation uneven. The present application uses an auxiliary positioning device to act. When installing the cooling pipe, the second fixing rod 402 is used to place the second limit block 2 on the cooling pipe, and the first limit block 1 is located between the cooling pipes. Then, the structural cavity 403 is started. The internal telescopic mechanism 404 and the telescopic rod 405 push the rod body of the No. 1 fixed rod 401 to move upward, and the No. 1 limit block 1 moves toward the direction of the adjacent cooling tube and makes the first fixed block 406 thereon close to the outer arc surface of the cooling tube, thereby positioning the distance between the cooling tubes and avoiding large errors in the distance between subsequent tube bodies that affect the uniformity of the cooling operation. After the positioning block 409 drives the second fixed block 414 to move to a suitable position along the surface of the cooling tube, the end of the wire 413 is wrapped around the slot 412 of the connecting block 411, thereby fixing the operating position of the cooling tube and ensuring stable operation of the cooling tube.

[0025] The first fixing rod 401 is symmetrically fixed with an elastic clip 415 near the bottom; when the elastic clip 415 is not in action, the moving ends of the elastic clip 415 are in contact; when the positioning block 409 is located inside the placement groove 407, the positioning rod 410 is arranged within the operating range of the elastic clip 415;

[0026] During operation, a pushing force is applied to the positioning rod 410, and the positioning rod 410 is disengaged from the operating range of the elastic clip 415, and the positioning block 409 is then disengaged from the placement groove 407, thereby achieving the coordinated operation of the entire auxiliary positioning device.

[0027] Working principle: During the concrete pouring process, concrete cooling pipes are needed to control the temperature of concrete in order to improve the quality and performance of concrete. When the cooling pipes are installed, positioning devices are required to cooperate with the operation. When the positioning devices of the above-mentioned concrete cooling pipes are used, they can only position and fix the cooling pipes at the specified positions, while there is still a certain error in the distance between the pipe bodies, which makes the concrete cooling operation uneven. The present application uses an auxiliary positioning device to work. When installing the cooling pipes, the No. 2 fixing rod 402 is used to place the No. 2 limit block 2 on the cooling pipe, and the No. 1 limit block 1 is located between the cooling pipes. Then, the telescopic mechanism 404 inside the structural cavity 403 is started, and the telescopic rod 405 pushes the No. 1 fixing rod. The rod body of rod 401 moves upward, and the No. 1 limit block 1 moves toward the direction of the adjacent cooling pipe and makes the first fixed block 406 thereon close to the outer arc surface of the cooling pipe, thereby positioning the distance between the cooling pipes and avoiding large errors in the distance between the subsequent pipe bodies that affect the uniformity of the cooling operation. Then, a pushing force is applied to the positioning rod 410, and the positioning rod 410 disengages from the operating range of the elastic clip 415, and the positioning block 409 disengages from the placement groove 407. After the positioning block 409 drives the second fixed block 414 to move to a suitable position along the surface of the cooling pipe, the end of the wire 413 is wrapped around the inside of the slot 412 of the connecting block 411, thereby fixing the operating position of the cooling pipe and ensuring the stable operation of the cooling pipe.
