[0029] Embodiment 1

[0030] Please refer to Figures 1 - 5 As shown, the underwater blasting construction platform drilling pipe returning device proposed in this embodiment includes a drill pipe 1, a casing 3, a spacing positioning plate 8, a drill tool male thread 11 and a drill tool female thread 12. The drill pipe 1 is movably sleeved with the casing 3. A convex pin 5 is fixed on the casing 3. At the same time, a spacing positioning plate 8 is movably sleeved in the casing 3. One end of the drill pipe 1 is threadedly connected to the bottom of the spacing positioning plate 8. A spacing limit plate 9 is fixed on the spacing positioning plate 8. A positioning card slot 10 is opened between the spacing positioning plate 8 and the spacing limit plate 9. The positioning card slot 10 corresponds to the convex pin 5 and is inserted with a retaining seat fork 13. The diameter of one end of the drill pipe 1 is matched with the diameter inside the casing 3 to improve the stability of inserting one end of the drill pipe 1 into the casing 3. At the same time, convex pins 5 are fixed at corresponding positions at both ends of the casing 3. The width of the convex pin 5 is matched with the depth inside the positioning card slot 10, so that the retaining seat fork 13 can be inserted from the outside of one convex pin 5 to the other convex pin 5, and the side part of the retaining seat fork 13 is attached to the inside of the positioning card slot 10 to realize the function of fixing the positions of the spacing positioning plate 8 and the spacing limit plate 9.

[0031] The working principle of the drilling pipe-returning device of the underwater blasting construction platform proposed in this embodiment is as follows: During use, the casing 3 is inserted onto the teeth of the male thread of the lower drill tool 11, and the casing 3 is lowered along with the drill tool until the spacer positioning plate 8 and the spacer limiting plate 9 inside the casing 3 abut against the top of the casing 3. As the male and female threads are engaged, the retaining fork 13 is then inserted onto the teeth outside the female thread of the upper drill tool and placed above the casing 3 and the spacer positioning plate 8. The driving force provided by the power turntable 2 is transmitted to the casing 3 through the drill pipe 1, the transmission turntable 14, and the stop pin 4. The casing 3 and the retaining fork 13 exert reaction forces on each other through the protruding pin 5, and then the drill tool can be disassembled.

[0032] Further, a power turntable 2 is installed at one end of the drill pipe 1, and a transmission turntable 14 is installed on the side of the casing 3.

[0033] More specifically, the power turntable 2 provides the driving rotational force, which is transmitted to the casing 3 through the transmission turntable 14 and the stop pin 4, causing the casing 3 to rotate.

[0034] Further, a stop pin 4 is fixed on the casing 3.

[0035] More specifically, stop pins 4 are fixed at corresponding positions on both sides of the casing 3 between the top and the middle. The stop pins 4 are used to transmit the driving force to the casing 3, enabling the casing 3 to rotate.

[0036] Further, sliding through slots 6 and limiting slots 7 are formed on the side of the casing 3. At the same time, positioning sliders 15 are fixed on the spacer positioning plate 8, and limiting sliders 16 are fixed on the side of the spacer limiting plate 9. The positioning sliders 15 and the limiting sliders 16 are both slidably connected in the sliding through slots 6 and the limiting slots 7.

[0037] More specifically, corresponding sliders are fixed at corresponding positions on both sides of the spacer positioning plate 8 and the spacer limiting plate 9. The sliders are slidably connected in the sliding through slots 6 and the limiting slots 7, thereby enabling the stable lowering of the drill pipe 1.

[0038] Further, stabilizing ridges 18 are provided in the sliding through slots 6 and the limiting slots 7. At the same time, stabilizing notches 17 are formed on the sides of the positioning sliders 15 and the limiting sliders 16. The stabilizing notches 17 are fitted to the sides of the stabilizing ridges 18.

[0039] More specifically, when the spacer positioning plate 8 and the spacer limiting plate 9 move up and down inside the casing 3, they slide along the sides of the stabilizing ridges 18 through the formed stabilizing notches 17, improving the stability of the up-and-down movement of the spacer positioning plate 8 and the spacer limiting plate 9 and preventing the phenomenon of flipping.

[0040] Further, a drill tool male thread 11 is fixed on the spacer limiting plate 9, and a drill tool female thread 12 is sleeved on the drill tool male thread 11.

[0041] More specifically, one section of the male drill tool joint 11 has an external thread, while one end of the female drill tool joint 12 has an internal thread. The male and female joints are connected through the internal and external threads. In a state where the power turntable 2 provides the driving rotational force, the male and female joints are separated, thereby realizing the disassembly of the drill pipe 1 below.

[0042] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
