[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments 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 any creative efforts shall fall within the scope of protection of the present invention.

[0020] See also Figure 1-5 As shown, the present invention is a deformation-resistant large-span steel member lifting fixture and a construction method thereof.

[0021] Example 1 See also Figure 1 、 Figure 2 、 Figure 3 and Figure 5 The present invention provides a technical solution: a lifting frame 1, a lifting assembly 2 is movably connected to the inner side of the lifting frame 1, auxiliary support assemblies 3 are fixedly installed on both the left and right ends of the lifting frame 1, and a lifting ring frame 4 is fixedly connected to the upper end of the lifting frame 1; Furthermore, the hoisting assembly 2 further includes an adjustment slot 201 provided on the inner side of the hoisting frame 1, and an adjustment horizontal plate 202 forms a snap-fit ​​sliding structure in the adjustment slot 201; By adjusting the horizontal plate 202 to slide inside the adjusting groove 201, the adjusting horizontal plate 202 drives the hinge chain 203 to move, and the hinge chain 203 links the hinged clamping arm rod 204 to move, thereby facilitating the adjustment of different positions for multi-position clamping of large-span steel members.

[0022] Furthermore, a hinge chain 203 is fixedly installed at the bottom of the adjustment horizontal plate 202, and the bottom of the hinge chain 203 is connected to a clamping arm rod 204, which is located at the lower end of the adjustment horizontal plate 202; By adjusting the cross plate 202, the clamp arm rod 204 is driven to adjust, so that the clamp arm rod 204 can clamp and fix the large-span steel member at multiple positions, thereby increasing the contact surface with the large-span steel member, improving stability and avoiding tilting during lifting.

[0023] Furthermore, the longitudinal section of the clamp arm 204 is an "L"-shaped structure, and the included angle of the clamp arm 204 is less than 90°; The “L”-shaped structure of the clamp arm 204 can improve the robustness of the clamp arm 204 and increase the bending resistance of the bend when the angle is less than 90°.

[0024] Furthermore, a reinforcing rib 209 is provided at the bend of the lower end of the clamp arm 204 to reinforce and support the clamp arm 204. A convex strip structure is evenly distributed on the inner side of the lower end of the clamp arm 204. By providing the reinforcing ribs 209 , when the clamp arm 204 clamps a large-span steel member, the reinforcing ribs 209 on one side facilitate improving the stability of the clamp arm 204 and preventing the clamp arm 204 from deforming over a long period of time.

[0025] Furthermore, the auxiliary support assembly 3 includes hinged supports 301 located on both sides of the hoisting frame 1, a steel cable 302 is provided on the inner side of the hinged supports 301, and a hook 303 is fixedly installed on the other end of the steel cable 302; The long-span steel member is assisted in lifting by the steel cable 302 in the hinged support 301 , and the hook member 303 at the other end of the steel cable 302 is convenient for hooking the hook point on the long-span steel member, thereby improving stability.

[0026] Furthermore, the eye frame 4 is located at the upper end of the hanging frame 1 and its longitudinal section is triangular. The lower end of the eye frame 4 is dispersedly provided with reinforcing rods fixedly connected to the hanging frame 1. The hoisting ring frame 4 on the hoisting frame 1 facilitates improving the stability of the hoisting, thereby reducing the tilting of the hoisting frame 1.

[0027] Specifically, before use, first integrate the lifting assembly 2 into the lifting frame 1, and then fix the lifting ring frame 4 on the lifting arm through the circular hole opened at the upper end. When the horizontal plate 202 is moved horizontally to the left and right, the clamping arm rod 204 can be driven to move synchronously as a whole. Since the inner side of the lower end of the clamping arm rod 204 is evenly distributed with convex strips, it can be used to lift large-span steel members for anti-slip contact. The reinforcing rib plate 209 is fixedly installed at the lower end bend of the clamping arm rod 204, and the clamping arm rod 204 and the reinforcing rib plate are fixedly installed. The longitudinal sections of the plates 209 are all L-shaped with an angle less than 90°. The reinforcing ribs 209 can strengthen the auxiliary support for the clamping arm 204 to prevent the clamping arm 204 from breaking, bending or deforming. The clamping arm 204 is symmetrically arranged front to back about the center line of the adjustment cross plate 202 and is evenly distributed below the lifting frame 1. This allows for multi-position clamping of large-span steel members. The clamping arm 204 is arranged at the lower end of the hinge chain 203 to form a rotating structure, which facilitates the positioning and clamping of large-span steel members of different sizes. The hook 303 is hung on the left and right ends of the large-span steel structure, thereby providing auxiliary support to improve stability. The two ends of the wire rope 302 are respectively fixedly connected to the hinged support 301 and the hook 303. The length of the wire rope 302 is limited. When the clamping arm 204 positions and clamps the large-span steel structure, it can extend outward at the distance of the wire rope 302 and provide a certain tension to tighten the large-span steel structure, thereby enhancing the stability of the large-span steel structure. The ring frame 4 is located at the upper end of the lifting frame 1 and its longitudinal cross-section is triangular. The lower end of the ring frame 4 is dispersed with reinforcing rods fixedly connected to the lifting frame 1, which can improve the stability of the lifting under the action of the ring frame 4, thereby reducing the overall tilt of the lifting frame 1.

[0028] Example 2 See also Figure 3 、 Figure 4 and Figure 5 In the present invention, a technical solution is provided: the hoisting assembly 2 includes an adjusting horizontal plate 202 and a clamping arm rod 204 for hoisting a large-span steel member; Furthermore, an adjustment plate 205 is fixedly mounted on the upper surface of the adjustment horizontal plate 202, and a slider 208 is fixedly mounted on one side of the adjustment plate 205; a slide groove 206 is provided on both sides of the upper surface of the hanging frame 1, and the slider 208 forms a sliding structure in the slide groove 206, and a plurality of limiting grooves 207 adapted to the slider 208 are provided on one side of the slide groove 206; When the adjustment cross plate 202 moves, the adjustment plate 205 on the upper surface can drive the slider 208 to slide inside the slide groove 206. After sliding to the specified position, the slider 208 is limited by the limiting groove body 207 on one side of the slide groove 206, thereby preventing the adjustment cross plate 202 from deviating during the hoisting of large-span steel components, affecting the safety of the hoisting.

[0029] Specifically, in combination with the first embodiment, an adjusting cross plate 202 is provided to form a transverse sliding structure in the hoisting frame 1 through the adjusting groove body 201, which can make the adjusting cross plate 202 move laterally stably as a whole, so that different positions of the long-span steel member can be clamped. An adjusting plate 205 is fixedly installed on the upper end of the adjusting cross plate 202, and a slider 208 is fixedly installed on the inner end of the adjusting plate 205. When the adjusting cross plate 202 is moved laterally left and right, the slider 208 slides laterally in the hoisting frame 1 through the sliding groove 206. After the adjusting cross plate 202 is moved to the specified position, the adjusting plate 205 can be engaged with the hoisting frame 1 through the limiting groove body 207. This arrangement can prevent the adjusting cross plate 202 from deviating when hoisting a large-span steel member, thereby affecting the safety of the hoisting. Among them, after the adjustment plate 205 is docked and engaged with the lifting frame 1 through the limiting groove body 207, when the large-span steel structure is hoisted, the clamping arm rod 204 will enable the adjustment plate 205 to be locked with the lifting frame 1 through the limiting groove body 207 under the self-weight of the large-span steel structure, so as to enhance the connection stability between the lifting component 2 and the lifting frame 1, and prevent the clamping arm rod 204 from causing the lifting component 2 to shake and displace on the lifting frame 1 when clamping and hoisting the large-span steel structure, causing the lifting frame 1 to tilt as a whole. The spliced ​​self-clamping connection structure makes the overall device more concise, reduces manufacturing costs, and is convenient for transportation and installation before use. The components of the device are conventional components, which are easy to disassemble and replace later, saving expenditure costs.

When adjusting different positions, the large-span steel member can be clamped in multiple positions; S2: Based on S1, when the horizontal plate 202 slides horizontally, the adjustment plate 205 on the upper surface of the horizontal plate 202 can drive the slider 208 to slide in the slide groove 206. After sliding to the specified position, the slider 208 can be limited and fixed by the limiting groove 207 on one side of the slide groove 206. S3: Finally, when the clamp arm 204 clamps the large-span steel member, the reinforcing rib 209 on one side of the lower end thereof can provide auxiliary and reinforced support for the clamp arm 204 in a stable manner.
