When an error occurs in positioning, use an unlocking device to reposition until the original design position is reached;

[0029] Step 6, repeat the above steps 4 and 5 in sequence to complete the positioning and arrangement of the entire large-volume concrete internal circulating cooling water pipe.

[0030] A rapid positioning device for circulating cooling water pipes of large-volume concrete comprises a water pipe positioning plate 1 and a steel bar positioning plate 2. A water pipe hook 3 is provided at one end of the water pipe positioning plate, a positioning block 4 is provided at the other end of the water pipe positioning plate, a convex groove 5 is penetrated through the positioning block, one end of a self-locking card 6 is hinged inside the convex groove, one end of a U-shaped spring piece 7 is symmetrically fixedly connected inside the convex groove, the other end of the U-shaped spring piece is fixedly connected to the self-locking card, one end of a pull rod 8 is fixedly connected to the self-locking card, and the other end of the pull rod extends out of the convex groove, a steel bar hook 9 is provided at one end of the steel bar positioning plate, and card strip grooves 10 are evenly opened on the steel bar positioning plate, one end of the steel bar positioning plate penetrates the convex groove, and the self-locking card extends into the card strip groove.

[0031] Specifically, the water pipe hook and the water pipe positioning plate are integrally formed, the positioning block and the water pipe positioning plate are integrally formed, and the steel bar hook and the steel bar positioning plate are integrally formed.

[0032] Specifically, a pull button 11 is provided at the other end of the pull rod.

[0033] Specifically, the water pipe hook is hooked with the circulating cold water pipe 14 , and the steel bar hook is hooked with the steel bars 13 on the large-volume concrete steel bar mesh 12 .

[0034] Working principle: the present invention hangs the steel bar hook on the upper steel bar mesh, hooks the water pipe hook at the bottom of the slide board onto the circulating cooling water pipe, and at the same time passes the steel bar positioning plate through the convex groove (note that the card strip groove surface faces the self-locking card side), and when the circulating cooling water pipe reaches the corresponding designed position, the self-locking card automatically pops into the card strip groove for self-locking and fixing to complete a single positioning device, wherein the U-shaped elastic gasket will keep the self-locking card in a closed state for a long time, and it will only work in an open state when the grooved card strip is inserted, and the U-shaped elastic gasket is between the fixed card bottom plate and the self-locking card, the upper part of the U-shaped elastic gasket is welded to the self-locking card, and the lower part is welded to the fixed card bottom plates on both sides (note to avoid the convex groove), and this device is welded to the convex groove, so as to achieve a fixing effect, and the unlocking device is a pull rod passing through the middle groove of the convex groove, and this pull rod is welded to the corresponding position of the self-locking card, and when the position of the circulating cooling water pipe is wrong, the pull rod is actuated to achieve the unlocking purpose, so that the engraved steel bar positioning plate moves to adjust its position. After the installation is completed in sequence according to the above method, a single positioning device forms a complete spatial stable skeleton, thereby achieving the positioning and fixing function of the circulating cooling water pipe. At the same time, a triple branch combination or a double branch combination or a combination of intervals can be used.
