[0016] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0017] like Figure 1 and Figure 2 The structure of a safe lifting device for a special-shaped structural member shown in the figure includes a hanger 1, a mounting seat 2 is provided on the hanger 1, a hoist 3 is installed on the mounting seat 2, and an adjustment seat 4 and a hook 6 are also included. The hoist 3 includes a winding wheel 31, and the winding wheel 31 is mounted on both sides of the mounting seat 2 through a support 32. A gear 33 is provided on the rotating shaft of the winding wheel 31, and the gears 33 on both sides are meshed and connected. The winding wheel 31 on one side is driven to rotate by a first motor 34. The adjustment seat 4 is slidably connected to both sides of the hanger 1, and the free end of the steel rope on the winding wheel 31 passes through the adjustment seat 4. The bottom of the hanger 1 is extended out, and a second motor 5 is provided on the hanger 1. The second motor 5 drives the connecting screw 51. The screw 51 is composed of a pair of screw shafts 52 with opposite thread rotation directions. A matching nut 53 is provided on the screw shaft 52, and the nut 53 is connected and fixed to the adjustment seat 4 on the corresponding side. The hook 6 is installed on the fixed seat 61, and the fixed seat 61 is fixed to the free end of the steel rope on the winding wheel 31. A movable seat 62 is provided on the fixed seat 61, and the movable seat 62 is sleeved on the hook 6. The fixed seat 61 and the movable seat 62 are connected by a spring 63.

[0018] As a preferred embodiment, a fixed pulley 41 is installed on the adjusting seat 4, and the free end of the steel rope on the winding wheel 31 passes around the fixed pulley 41 and passes through the bottom of the adjusting seat 4.

[0019] As a further improvement, a through hole 42 is provided on the adjusting seat 4 , and the steel rope of the winding wheel 31 passes through the through hole 42 and extends out of the bottom of the adjusting seat 4 .

[0020] As a preferred embodiment, the hook 6 is composed of a straight rod and a U-shaped rod in one body, and one end of the U-shaped rod of the hook 6 can extend out of the outside of the movable seat 62 .

[0021] The present invention mentions a safe lifting structure for special-shaped structural parts. By setting an adjustable adjustment seat, when lifting special-shaped structural parts of different sizes, they can be stably lifted on both sides of the structural parts, thereby ensuring their safety and stability during the lifting and lowering process.

[0022] Specifically, when hoisting and transporting a structural member, the positions of the adjustment seats 4 on both sides of the hanger 1 are adjusted according to the size of the hoisted structural member, so that the steel rope passing through it can correspond to the lifting rings on both sides of the structural member, thereby performing hoisting.

[0023] The adjustment of the adjustment seat 4 can be achieved by driving the screw mechanism through the second motor 5. The screw 51 is composed of two screw shafts 52 with opposite thread rotation directions. The second motor 5 drives it to rotate synchronously, and the nut 53 thereon drives the adjustment seats 4 on both sides to slide synchronously, thereby realizing synchronous adjustment of their positions.

[0024] After the position of the adjustment base 4 is adjusted, the first motor 34 drives the rotation of the gear 33, and the two winding wheels 31 rotate in opposite directions, thereby achieving synchronous retraction and release of the steel ropes on the two winding wheels 31. When the steel ropes are lowered, the lifting can be achieved by connecting the hook 6 to the lifting ring on the structural member.

[0025] The hook 6 is installed on the fixed seat 61. When connecting the lifting ring, the movable seat 62 can be pressed to expose the U-shaped end of the hook, so that it can be connected to the lifting ring. Then the movable seat 62 is loosened. Under the action of the spring 63, the U-shaped end of the hook 6 is sealed so that it will not fall off the lifting ring. At the same time, it can be clamped on the lifting ring to ensure safety and stability during the lifting process.

[0026] The embodiments described above are merely descriptions of preferred embodiments of the present invention and are not intended to limit the concept and scope of the present invention. Any modifications and improvements made to the technical solution of the present invention by a person of ordinary skill in the art without departing from the design concept of the present invention shall fall within the scope of protection of the present invention. The technical content for which protection is sought in the present invention is fully set forth in the claims.
