[0031] The first frame is provided with four positioning auxiliary components 1, which are distributed in a rectangular array, and the positioning auxiliary components 1 are used to achieve primary positioning assistance for sinking caissons of different diameters;

[0032] The bottom of the "U"-shaped base plate 100 and the bottom of the "U"-shaped base plate 200 are both installed with a positioning auxiliary component 2, and the two positioning auxiliary components 2 are arranged in upper and lower positions. The positioning auxiliary component 2 is used to realize secondary positioning assistance for sinking construction of caissons of different diameters;

[0033] The second positioning auxiliary component includes four strip-shaped connecting seats 101, on which a rectangular sliding block 102 is slidably mounted, one end of which is fixedly mounted a second "concave" pulley seat 103, on which a second fixed pulley 104 is rotatably mounted, and one end of the rectangular sliding block 102 away from the second "concave" pulley seat 103 is fixedly mounted a hollow tube 105;

[0034] A servo motor 300 is fixedly installed at the bottom of the "return" type substrate 100 and the "return" type substrate 2 200, a winding wheel 400 is fixedly installed on the output shaft of the servo motor 300, and a wire rope 106 is wound around the winding wheel 400. A short rod 107 is rotatably installed at the bottom of the "return" type substrate 100 and the "return" type substrate 2 200, and a guide wheel 109 is fixedly sleeved on the short rod 107. One end of the wire rope 106 away from the corresponding winding wheel 400 passes through the corresponding three hollow tubes 105 in sequence and is fixedly connected to the last hollow tube 105, and the wire rope 106 is wound around the corresponding guide wheel 109.

[0035] When positioning is required through the fixed pulley 104, the servo motor 300 is directly started, and the output shaft of the servo motor 300 drives the winding wheel 400 to rotate. The winding wheel 400 tightens the wire rope 106 during the rotation process. The wire rope 106 drives the hollow tube 105 to move during the tightening process. The hollow tube 105 drives the rectangular sliding block 102 to move. The rectangular sliding block 102 pushes the "concave" pulley seat 103 to move. The "concave" pulley seat 103 drives the fixed pulley 104 to move, so that the four fixed pulleys 104 are close to each other, and then the positioning auxiliary work of the caisson is realized;

[0036] The positioning auxiliary component 1 includes a mounting block 15, a mounting block 26, a threaded rod 7, an internally threaded sleeve 8, a "concave" pulley seat 19 and a fixed pulley 10.

[0039] Through the above technical solution, the internal threaded sleeve 8 can be limited, and the movable "concave" pulley seat 9 can be limited indirectly, so as to avoid the "concave" pulley seat 9 from deflecting when moving.

[0047] When in use, the crane is mounted on the caisson through the lifting block 12, and then the threaded rod 7 is rotated. Under the action of the thread and the movable limit block 11, the internal threaded sleeve 8 can drive the third round rod, the "concave" pulley seat 9 and the fixed pulley 10 to move, so that the fixed pulley 10 contacts the outer wall of the caisson, and the movable limit block 11 can limit the movement of the "concave" pulley seat 9 to avoid the "concave" pulley seat 9 and the fixed pulley 10 from deflecting. Therefore, the device is simple to operate and can be used to assist in positioning caissons of different diameters and specifications, thereby improving the adaptability of the device.

[0048] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention.
