[0022] The technical solution in the embodiment of the present application is to solve the problems mentioned in the above background technology, and the overall idea is as follows:

[0023] See also Figure 1-Figure 4A pulley assembly hoisting and flipping device comprises two hanging arms hinged together in an X shape, each of the hanging arms is interspersed with a chain, an adjustable pitching member is arranged at the lower end of the hanging arm, a claw is rotatably connected to the pitching member to match the belt groove of the pulley, and a locking member is arranged between the two hanging arms. The two hanging arms 10 are pulled by a pull ring to produce a clamping action, and the two claws 60 clamp the flat pulley, the pitching member 40 is used to adjust the level of the two claws 60 so that they can rotate coaxially, and the locking member 50 is used to lock the angle of the two hanging arms 10, thereby preventing loosening, and the clamping is more stable, and it can also adapt to pulleys of different diameters, thereby improving versatility.

[0024] See also Figure 1-Figure 4 , a lifting ring 30 is interspersed between the two links 20. Here, by connecting the lifting ring 30 with the lifting equipment, the two links 20 can be directly pulled by the lifting ring 30, and then the two booms 10 are pulled together to produce a clamping action.

[0025] See also Figure 1-Figure 4 The pitching member 40 includes a base 41, a claw 60 is rotatably connected to the base 41, and the base 41 is hinged to the lower end of the boom 10. Here, the base 41 is used to connect the claw 60. Since the angles of the two booms 10 are different after clamping pulleys of different diameters, the two claws 60 are not coaxial and cannot rotate after clamping the pulleys. Therefore, the rotation axis of the claw 60 is adjusted by the pitching member 40, so that the two claws 60 remain coaxial after clamping the pulleys for rotation.

[0026] See also Figure 1-Figure 4 The pitch member 40 further includes a rod sleeve 42 and a screw 43, the screw 43 is plugged with the rod sleeve 42, and the screw 43 and the rod sleeve 42 are respectively hinged to the boom 10 and the base 41. Here, the screw 43 and the rod sleeve 42 are telescopically adjusted with the pitch angle of the base 41.

[0027] See also Figure 1-Figure 4 The rod sleeve 42 mouth is rotatably connected with a nut 44, and the nut 44 is threadedly connected with the screw rod 43. Here, rotating the nut 44 can push the screw rod 43 to extend and retract, thereby adjusting and locking the pitch angle of the base 41.

[0028] See also Figure 1-Figure 4 , a scale 45 is provided on the minor diameter of the screw rod 43, and an observation slot 46 is provided on the nut 44 corresponding to the scale 45. Here, according to the diameter of the pulley to be clamped, the nut 44 is rotated to a specified angle so that the corresponding scale 45 can be seen through the observation slot 46, thereby ensuring that the claw 60 on the base 41 is in a horizontal state after clamping, so that it can rotate normally.

[0029] See also Figure 1-Figure 4The locking member 50 includes a fan-shaped toothed disc 51 and a toothed claw 52. The toothed disc 51 is fixedly connected to one of the suspension arms 10, and the toothed claw 52 is slidably connected to the other suspension arm 10. The toothed claw 52 is engaged with the toothed disc 51. Here, when the toothed claw 52 is pulled apart, the two suspension arms 10 can deflect normally. After clamping the pulley, the toothed claw 52 is engaged with the toothed disc 51, thereby locking the angles of the two suspension arms 10, so as to prevent the pulley from being loosened from the two claws 60.

[0030] See also Figure 1-Figure 4 The locking member 50 further includes a spring 53, which is pressed against the toothed claw 52. Here, after clamping the pulley, the toothed claw 52 is released, and the spring 53 can push the toothed claw 52 to bite on the toothed disc 51, thereby locking the angles of the two booms 10.

[0031] When the present application is used: the nut 44 is rotated to a specified angle so that the corresponding scale 45 can be seen through the observation slot 46, the toothed claw 52 is pulled open to cooperate with the lifting equipment to lift the lifting ring 30, the two links 20 are pulled, and then the two lifting arms 10 are pulled together to generate a clamping action to clamp the pulley on the horizontal plane, and then the toothed claw 52 is released, and the spring 53 pushes the toothed claw 52 to bite into the toothed disc 51, thereby locking the angle of the two lifting arms 10, and as the pulley is lifted, the pulley can be rotated to stand up for installation, and then the toothed claw 52 can be pulled open to release the pulley.

[0032] In summary, the two arms 10 are pulled by the pull ring to generate a clamping action, and the two claws 60 clamp the flat pulley. The pitch member 40 is used to adjust the level of the two claws 60 so that they can rotate coaxially, and the locking member 50 is used to lock the angle of the two arms 10 to avoid loosening. The clamping is more stable and can also adapt to pulleys of different diameters, thereby improving versatility.

[0033] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
