[0006] Preferably, the shift rod passes through the upper part of the lifting ring, and the shift rod and the lifting ring are movably connected. The tension spring is sleeved on the shift rod on the left side of the lifting ring, and both ends of the tension spring are fixedly connected to the pull rod and the lifting ring respectively.

[0007] Preferably, the bayonet is arranged at an angle, and the bottom of the bayonet is located on the right side of the center of the fixed wheel.

[0008] Preferably, the bayonet width gradually increases from the center of the fixed wheel toward the outside.

[0009] Preferably, the steel wire rope is fixedly connected to the top of the fixed plate, and the lifting ring is fixedly connected to the bottom of the fixed plate.

During the lifting process, the fixed wheel rotates clockwise under the tension, and when the bayonet is blocked by the lifting ring, the left side of the fixed wheel presses against the left side of the lifting ring, and the fixed ring stops rotating, fixing the steel wire rope in the bayonet, thereby enhancing the safety of lifting building materials. When the pull rod is released, the tension spring contracts, and the two ends of the tension spring are fixedly connected to the pull rod and the lifting ring. The tension spring pulls the push rod, and the push rod drives the gear rod to move to the right, closing the opening at the top of the lifting ring, thereby further enhancing the safety of lifting building materials.

[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0016] See also Figure 1-3The utility model provides a technical solution: a lifting device for construction, including a fixed plate 1 and a wire rope 2, a lifting ring 3 is provided at the bottom of the fixed plate 1, a gear rod 4 is provided on the upper part of the lifting ring 3, a pull rod 9 is provided at the left end of the gear rod 4, a tension spring 5 is provided on the gear rod 4, a positioning shaft 6 is provided inside the lifting ring 3, a fixed wheel 7 is provided on the positioning shaft 6, and a bayonet 8 is provided on the fixed wheel 7. When the lifting ring 3 is used to lift building materials, the pull rod 9 is pulled to the left, the pull rod 9 drives the gear rod 4 to move to the left, the tension spring 5 is stretched, the upper opening of the lifting ring 3 is opened, and the wire rope for bundling building materials is hung on the lifting ring 3 The bayonet 8 on the inner fixed ring 7 is located on the right side of the center of the fixed wheel 7. During the lifting process, the fixed wheel 7 rotates clockwise under tension. When the bayonet 8 is blocked by the lifting ring 3, the left side of the fixed wheel 8 presses against the left side of the lifting ring 3. The fixed ring 7 stops rotating, fixing the wire rope in the bayonet 8, enhancing the safety of lifting building materials, loosening the pull rod 9, the tension spring 5 contracts, and the two ends of the tension spring 5 are fixedly connected to the pull rod 9 and the lifting ring 3. The tension spring 5 pulls the push rod 9, and the push rod 9 drives the gear lever 4 to move to the right, closing the opening at the top of the lifting ring 3, further enhancing the safety of lifting building materials.

[0017] Among them, the gear rod 4 passes through the upper part of the lifting ring 3, and the gear rod 4 is movably connected to the lifting ring 3. The tension spring 5 is sleeved on the gear rod 4 on the left side of the lifting ring 3. The two ends of the tension spring 5 are fixedly connected to the pull rod 9 and the lifting ring 3 respectively. After the pull rod 9 moves to the left and drives the gear rod 4 to move, after the pull rod 9 is released, the tension spring 5 contracts, pulling the pull rod 9 to move to the right, and the pull rod 9 drives the gear rod 4 to move to the right, closing the opening at the upper part of the lifting ring 3;

[0018] The bayonet 8 is set obliquely, and the bottom of the bayonet 8 is on the right side of the center of the fixed wheel 7. When the bayonet 8 is hung with a wire rope for hoisting, the fixed wheel 7 is subjected to force to the right of the center of the fixed wheel 7. The fixed wheel 7 rotates clockwise, rotating the bayonet 8 to contact the inner wall of the lifting ring 3, sealing the bayonet 8, and enhancing the safety of hoisting building materials;

[0019] The width of the bayonet 8 gradually increases from the center of the fixed wheel 7 to the outside, making it easier for the wire rope to be hung on the bayonet 8;

[0020] The steel wire rope 2 is fixedly connected to the top of the fixed plate 1 , and the lifting ring 3 is fixedly connected to the bottom of the fixed plate 1 .

[0021] Working principle: When the lifting ring 3 is used to lift the building materials, the pull rod 9 is pulled to the left, the pull rod 9 drives the shift rod 4 to move to the left, the tension spring 5 is stretched, the upper opening of the lifting ring 3 is opened, and the steel wire rope for bundling the building materials is hung in the bayonet 8 on the fixed ring 7 set in the lifting ring 3. The bayonet 8 is on the right side of the center of the fixed wheel 7. During the lifting process, the fixed wheel 7 rotates clockwise under the tension. When the bayonet 8 is blocked by the lifting ring 3, the left side of the fixed wheel 8 presses against the left side of the lifting ring 3, and the fixed ring 7 stops rotating, fixing the steel wire rope in the bayonet 8, thereby enhancing the safety of lifting the building materials. The pull rod 9 is released, the tension spring 5 contracts, and the two ends of the tension spring 5 are fixedly connected to the pull rod 9 and the lifting ring 3. The tension spring 5 pulls the push rod 9, and the push rod 9 drives the shift rod 4 to move to the right, closing the opening at the top of the lifting ring 3, thereby further enhancing the safety of lifting the building materials.
