DETAILED DESCRIPTION OF THE INVENTION

[0015] 1 to 6, a deep well thin-walled pipe lifting and construction device according to one embodiment of the present invention includes a lifting arm 1, a lifting bracket 3, a control cylinder 4, and a motor 62. An electric hoist is installed on the surface of the lifting arm 1, a lifting rope 2 is connected to the lifting arm 1 via the electric hoist, the lifting bracket 3 is fixedly connected to the lifting rope 2, the control cylinder 4 is fixedly connected to the outer surface of the lifting bracket 3, a chuck 41 is fixedly connected to the output shaft of the control cylinder 4, a connecting groove 42 is opened on the surface of the chuck 41, a contact plate 43 is installed inside the connecting groove 42, a support spring 44 is fixedly connected to the surface of the contact plate 43, a telescopic cylinder is installed on the surface of the lifting bracket 3, a control block 5 is movably connected to the inside of the lifting bracket 3 via the telescopic cylinder, and a connecting block 51 is fixedly connected to one surface of the control block 5. a fixed block 6 fixedly connected to another surface of the control block 5; a control groove 67 formed inside the fixed block 6; a second gear 66 movably connected inside the control groove 67; a first gear 64 fixedly connected to the output shaft of the motor 62; a fixed rod 65 fixedly connected to the surface of the first gear 64; a connecting rod 63 fixedly connected to the surface of the second gear 66; a clamping plate 61 fixedly connected to the surface of the connecting rod 63; a stopper groove 31 and a moving groove 32 formed on the inner wall of the hanging bracket 3; a rotating plate 52 and a stopper rod 53 fixedly connected to both sides of the control block 5;

[0016] Furthermore, the lifting bracket 3 is lifted below the lifting arm 1 via the lifting rope 2, and the output shaft of the telescopic cylinder of the lifting bracket 3 abuts against and contacts the surface of the control block 5. Through the connection between the telescopic cylinder of the lifting bracket 3 and the control block 5, the control block 5 achieves the control effect on the operating angle of the lifting bracket 3. Since the output shaft of the telescopic cylinder abuts against and contacts the surface of the control block 5 but is not connected, after the chuck 41 is connected to the connecting block 51, it does not affect the control block 5's control operation of the operating position of the lifting bracket 3.

[0017] Furthermore, the control block 5 is rotatably connected to the hanging bracket 3 via the rotating plate 52 and the moving groove 32, and the stopper rod 53 is slidably connected to the stopper groove 31, and the cross section of the moving groove 32 is "T" shaped. By connecting the control block 5 to the rotating plate 52, the operating angle and position of the control block 5 on the hanging bracket 3 can be changed by connecting the rotating plate 52 to the moving groove 32.

[0018] Furthermore, a groove is opened on the surface of the connecting block 51, and the chuck 41 is inserted into the connecting block 51 through the groove. Two sets of connecting grooves 42 are opened opposite each other on both sides of the chuck 41. Through the connection between the control block 5 and the connecting block 51, the connection between the groove in the connecting block 51 and the chuck 41 realizes the support effect for the operating angle of the hanging bracket 3 of the control block 5.

[0019] Furthermore, the abutment plate 43 is elastically connected to the connecting groove 42 via the support spring 44, and the outer surface of the abutment plate 43 abuts and contacts the inner wall of the groove in the connecting block 51 via the chuck 41. The connection between the chuck 41 and the connecting groove 42, and the connection between the abutment plate 43 and the support spring 44, realizes the elastic connection effect of the abutment plate 43 in the chuck 41, and the action of the abutment plate 43 improves the tightness of the connection between the chuck 41 and the connecting block 51.

[0020] Two sets of fixed blocks 6 are connected to both ends of the control block 5, and two sets of clamping plates 61 are symmetrically distributed on both sides of the fixed block 6. The two sets of clamping plates 61 are connected to each other via a second gear 66 so that they can rotate in opposite directions. Both ends of the fixed rod 65 are fixedly connected to the surface of the first gear 64, and the first gear 64 is rotatably connected to the second gear 66 through meshing. Through the connection between the fixed block 6 and the control block 5, the connection between the motor 62 and the first gear 64 causes the first gear 64 to rotate, which in turn drives the second gear 66 to rotate, further rotating the clamping plates 61 and completing the clamping operation for the thin-walled tube. The action of the fixed rod 65 realizes synchronous clamping operation between the clamping plates 61, improving the stability of the clamping operation.

[0021] When lifting the thin-walled pipe, the motor 62 rotates to rotate the first gear 64, and the first gear 64 and the second gear 66 mesh and rotate, causing the clamping plate 61 to clamp the thin-walled pipe. The lifting of the thin-walled pipe is completed through the action of the lifting rope 2. After the lifting is completed, the telescopic cylinder of the lifting bracket 3 is activated to change the operating angle of the lifting bracket 3 of the control block 5, changing the thin-walled pipe's horizontal position to a vertical position. The connection between the chuck 41 and the connecting block 51 provides support for the operating angle of the control block 5. The control cylinder 4 changes the operating position of the lifting bracket 3 of the control block 5, ensuring that the thin-walled pipe is lifted vertically, and the operation of inserting the thin-walled pipe into the deep well can be completed.
