[0019] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] like Figure 1 and Figure 2 As shown in Embodiment 1, a tool for positioning and aligning a concrete pipe includes: a limiting frame 1 and an insert rod 2. The limiting frame 1 is an isosceles triangle, and the insert rod 2 is L-shaped. The insert rod 2 is mounted on the limiting frame 1, and the bottom end of the insert rod 2 can be inserted into the interior of the concrete pipe. The outer wall of the insert rod 2 can contact the end face of the concrete pipe, and the bottom end of the limiting frame 1 contacts the outer wall of the concrete pipe.

[0021] When using, attach the two tools to the top and side of the concrete joint to be joined, so that the bottom end of the limiting frame 1 contacts the outer wall of the concrete pipe, insert the bottom end of the insertion rod 2 into the inside of the concrete pipe, and flip the limiting frame 1 so that the bottom end of the insertion rod 2 and the bottom end of the limiting frame 1 contact the inner and outer walls of the concrete pipe respectively, so that the tools are properly placed on the concrete pipe.

[0022] After placement, the concrete pipe is hoisted and connected. This tool limits the position of the concrete pipe. Once connected, the tool can be rotated to remove it. The gap created by the tool can be eliminated by slightly pushing the concrete pipe in.

[0023] The insertion rod 2 is fixedly installed on the limiting frame 1, and the bottom end of the insertion rod 2 is parallel to the bottom end of the limiting frame 1.

[0024] When the rotating limit frame 1 is rotated, it can drive the insertion rod 2 to rotate. When the insertion rod 2 rotates to a state parallel to the cross section of the concrete pipe, it is easy to remove the insertion rod 2 from the gap between the two concrete pipes.

[0025] like Figures 3 to 5 As shown, in Embodiment 2, a limiting sleeve 1-1 is fixedly installed on the side of the limiting frame 1, and the insert rod 2 is sleeved inside the limiting sleeve 1-1. A limiting groove 1-2 is opened on the limiting sleeve 1-1, and the limiting groove 1-2 is concave.

[0026] A sliding block 2-1 is fixedly installed on the outer wall of the insertion rod 2. The included angle between the sliding block 2-1 and the insertion rod 2 is set to 90 degrees. The sliding block 2-1 is slidably installed in the limiting groove 1-2.

[0027] When the sliding block 2-1 is at the end of the limiting groove 1-2, the sliding block 2-1 is blocked by the limiting groove 1-2, which can lock the insertion rod 2 in a parallel or perpendicular state to the limiting frame 1, so that when the limiting frame 1 deflects, the insertion rod 2 will rotate.

[0028] When the insertion rod 2 is parallel to the limiting frame 1, when the limiting frame 1 deflects, the bottom end of the insertion rod 2 can contact the inner wall of the concrete pipe. The bottom end of the limiting frame 1 and the bottom end of the insertion rod 2 clamp the cross section of the concrete pipe, so that the limiting frame 1 can be placed on the concrete pipe.

[0029] When the insertion rod 2 is perpendicular to the limiting frame 1, the limiting frame 1 deflects, allowing the insertion rod 2 to be removed from the gap between the two concrete pipes.

[0030] The insertion rod 2 is fixedly installed with a pressing rod 2-2. A spring 2-3 is sleeved on the outer wall of the pressing rod 2-2. The top end of the spring 2-3 is fixedly installed on the inner wall of the top end of the limiting sleeve 1-1, and the bottom end of the spring 2-3 is rotatably installed on the top end of the insertion rod 2.

[0031] When it is necessary to switch the state of the insertion rod 2, press down the pressing rod 2-2 to compress the spring 2-3, so that the sliding block 2-1 is at the bottom of the limiting groove 1-2. At this time, rotate the pressing rod 2-2 to let the sliding block 2-1 slide at the bottom of the limiting groove 1-2. When the sliding block 2-1 slides to the other side of the limiting groove 1-2, release the pressing rod 2-2, so that the insertion rod 2 is subjected to the force of the spring 2-3, so that the insertion rod 2 can enter the end of the limiting groove 1-2. The sliding block 2-1 is subjected to the force of the limiting groove 1-2, so that the insertion rod 2 remains parallel or perpendicular to the limiting frame 1.

[0032] Two limiters 1 are provided on both sides of the concrete pipe. A bidirectional threaded sleeve 3 is provided between the limiters 1 on the same side. Both ends of the bidirectional threaded sleeve 3 are threadedly connected to threaded rods 3-1. The end of the threaded rod 3-1 away from the bidirectional threaded sleeve 3 is rotatably installed on the outer wall of the limiter sleeve 1-1.

[0033] Rotating the bidirectional threaded sleeve 3 can drive the threaded rods 3-1 on both sides to move in opposite directions, causing the limit frame 1 to deflect.

[0034] When the insertion rod 2 is parallel to the limiting frame 1, when the limiting frame 1 deflects, the bottom end of the insertion rod 2 can contact the inner wall of the concrete pipe. The bottom end of the limiting frame 1 and the bottom end of the insertion rod 2 clamp the cross section of the concrete pipe, so that the limiting frame 1 can be placed on the concrete pipe.

[0035] When the insertion rod 2 is perpendicular to the limiting frame 1, the limiting frame 1 deflects, allowing the insertion rod 2 to be removed from the gap between the two concrete pipes.

[0036] A clamp 4 is provided between the limit frames 1 on the same side. The clamp 4 is fitted inside the limit frame 1, and the opposite ends of the two clamps 4 are threadedly connected with bolts 4-1.

[0037] When installing the tool, pass the clamp 4 between the two limit frames 1, align the two clamps 4, and rotate the bolt 4-1 so that the clamp 4 tightly contacts the bottom end of the limit frame 1 with the outer wall of the concrete pipe.

[0038] When the limiting bracket 1 can be placed on the concrete pipe, the bottom end of the limiting bracket 1 keeps in contact with the outer wall of the concrete pipe. When connecting two concrete pipes, it can prevent the pipe from shifting, causing the tool to fall off and the pipes to become misaligned.

[0039] When the insert rod 2 is removed from the gap between the two concrete pipes, the bottom end of the limiting frame 1 remains in contact with the outer wall of the concrete pipe. After the two concrete pipes are joined, the bolt 4-1 is loosened, which can drive the entire device to slide on the outer wall of the concrete pipe and move the device to the outer wall of another concrete pipe that needs to be joined. Then the bidirectional threaded sleeve is rotated in the opposite direction, so that the bottom end of the insert rod 2 enters the inside of the concrete pipe.

[0040] Then slide the sliding block 2-1 to the other end of the limiting groove 1-2, so that the insertion rod 2 and the limiting frame 1 are in a parallel state, so that the limiting frame 1 can be placed on the concrete pipe.

[0041] Compared to Example 1, Example 2 has the effect of improving the stability of the tool and the docking accuracy of the pipe during docking.

[0042] The technical scope of this utility model is not limited to the contents of the above description. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the scope of this utility model.
