Detailed implementation manners

[0028] In order to clearly and completely describe the purpose, technical solution of the present invention and make the advantages more clear, the following further details the embodiments of the present invention with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, rather than all of the embodiments, and are only used to explain the embodiments of the present invention, not to limit the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0029] Please refer to Figures 1 to 10, the present invention provides a technical solution: a steel structure hoisting and fixing device, including a first buckle plate 1 and a second buckle plate 2. The first buckle plate 1 and the second buckle plate 2 are respectively sleeved on both sides of the steel structure cross beam 3. A connection and reinforcement component is provided between the bottom ends of the first buckle plate 1 and the second buckle plate 2. An assembly limiting part is provided at the top ends of the first buckle plate 1 and the second buckle plate 2 to realize the fixation after the first buckle plate 1 and the second buckle plate 2 are sleeved on the steel structure cross beam 3. The first buckle plate 1 and the second buckle plate 2 are assembled into an "I"-shaped frame, and embedding grooves 9 are formed on the inner ring surfaces of the first buckle plate 1 and the second buckle plate 2. A rubber gasket 10 is fixed inside the embedding groove 9. The thickness of the rubber gasket 10 is greater than the depth of the embedding groove 9. After the first buckle plate 1 and the second buckle plate 2 are buckled on both sides of the first buckle plate 1 and limited by the assembly limiting part and the connection and reinforcement part, the rubber gasket 10 is compressed to generate elastic deformation; the friction between the first buckle plate 1, the second buckle plate 2 and the steel structure cross beam 3 is increased to ensure that after the first buckle plate 1 and the second buckle plate 2 are sleeved on both sides of the steel structure cross beam 3, when the assembly limiting part and the connection and reinforcement part are locked, it effectively avoids the phenomenon that the first buckle plate 1 and the second buckle plate 2 slide along the side of the steel structure cross beam 3 when hoisting the steel structure cross beam 3 through the first buckle plate 1 and the second buckle plate 2.

[0030] The connection and fixation part includes a guiding groove 4, a sliding block 5, a perforation 6, a screw rod 7 and a nut 8. The guiding groove 4 is formed on the bottom plate of the first buckle plate 1. One end of the sliding block 5 is fixed on the bottom plate of the second buckle plate 2. A perforation 6 is formed at one end of the guiding groove 4. One end of the screw rod 7 is fixed on the surface of the sliding block 5. The other end of the screw rod 7 penetrates through the perforation 6. The nut 8 is sleeved and screwed on the other end of the screw rod 7; the guiding groove 4 is a "convex"-shaped groove, the length of the long side of the guiding groove 4 is less than the length of the long side of the bottom plate of the first buckle plate 1. The sliding block 5 is a "convex"-shaped plate-like structure. The sliding block 5 is inserted into the guiding groove 4, and the plate length of the sliding block 5 is equal to the length of the long side of the guiding groove 4; there are two groups of guiding grooves 4, and the two groups of guiding grooves 4 are symmetrically distributed with respect to the embedding groove 9. After the nut 8 and the screw rod 7 are locked, the rubber gaskets 10 on the inner sides of the first buckle plate 1 and the second buckle plate 2 tightly clamp both sides of the first buckle plate 1.

[0031] During use, when the first buckle plate 1 and the second buckle plate 2 are respectively sleeved on the steel structure cross beam 3 from both sides and pushed forward, the sliding block 5 is inserted into the first buckle plate 1. As the sliding block 5 continues to be pushed along the guiding groove 4, the screw rod 7 passes through the perforation 6. When one end of the screw rod 7 exposes from the perforation 6, the nut 8 is sleeved on the corresponding screw rod 7 and screwed and locked. In this way, the first buckle plate 1 and the second buckle plate 2 clamp the steel structure cross beam 3, and the two rubber gaskets 10 tightly clamp both sides of the first buckle plate 1 to generate elastic deformation.

[0032] The assembled limiting part includes a side groove 11, an elastic hanging plate 12 and a clamping strip 13. The side groove 11 is opened on the top plate of the first buckle plate 1. There are two side grooves 11, and the two side grooves 11 are symmetrically distributed with respect to the first buckle plate 1. The elastic hanging plates 12 and the side grooves 11 correspond one by one. The elastic hanging plate 12 is fixed on the surface of the second buckle plate 2. After the first buckle plate 1 and the second buckle plate 2 are assembled, the elastic hanging plate 12 is inserted into the side groove 11. The clamping strip 13 is fixed on the surface of the elastic hanging plate 12. And after the elastic hanging plate 12 passes through the corresponding side groove 11, the clamping strip 13 is on the side of the elastic hanging plate 12 away from the second buckle plate 2; The clamping strip 13 is in the shape of a right-angled trapezoidal strip, and the inclined surface of the clamping strip 13 faces away from the second buckle plate 2. A pull ring 14 is fixed on the surface of the elastic hanging plate 12, and the pull ring 14 and the clamping strip 13 are symmetrically distributed with respect to the elastic hanging plate 12.

[0033] During use, when the slider 5 is pushed along the guiding groove 4, the elastic hanging plate 12 aligns with the corresponding side groove 11. As the elastic hanging plate 12 is pushed, the top plate of the first buckle plate 1 squeezes the clamping strip 13 along the inclined surface. The clamping strip 13 tenses the elastic hanging plate 12 to deform. The elastic hanging plate 12 is pushed along the corresponding side groove 11 until the clamping strip 13 passes over the side groove 11, and then the elastic hanging plate 12 rebounds. The clamping strip 13 is stuck on the side of the top plate of the first buckle plate 1 away from the second buckle plate 2, realizing the top limit when the first buckle plate 1 and the second buckle plate 2 are connected; When disassembling the first buckle plate 1 and the second buckle plate 2, it is necessary to first unscrew and remove the nut 8 from the screw rod 7, and then pinch the pull ring 14 to tense the elastic hanging plate 12 to deform. When the elastic hanging plate 12 pulls the clamping strip 13 and is not blocked by the top plate of the first buckle plate 1, the elastic hanging plate 12 is pushed out of the side groove 11, and the second buckle plate 2 and the first buckle plate 1 are separated.

[0034] And lifting parts are provided at the tops of both the first buckle plate 1 and the second buckle plate 2 for hanging a lifting rope. The lifting part includes a lifting tool 15, an assembling groove 16 and a reserved hole 17. There are two lifting tools 15, and the two lifting tools 15 are respectively fixed at the tops of the first buckle plate 1 and the second buckle plate 2. The assembling groove 16 is in the shape of an "L" - shaped groove, and the assembling groove 16 is opened on the surface of the lifting tool 15. After the first buckle plate 1 and the second buckle plate 2 are assembled, the two lifting tools 15 are spliced in a staggered manner through the two assembling grooves 16. A reserved hole 17 is opened on the surface of the lifting tool 15; A reinforcing sleeve ring 18 is inserted and fixed inside the reserved hole 17, and the reinforcing sleeve ring 18 is in the shape of a "T" - shaped round tube.

[0035] During use, when the first buckle plate 1 and the second buckle plate 2 are buckled on both sides of the steel structure cross - beam 3 and are limited by the assembled limiting part and the connecting and reinforcing part, the two lifting tools 15 are spliced in a staggered manner, and the reserved holes 17 of the two lifting tools 15 are opposite. The lifting rope or hook is passed through the reserved hole 17 and the reinforcing sleeve ring 18 for lifting work.

[0036] The detailed usage process is as follows:

[0037] Working of the connection and reinforcement component: When the first buckle plate 1 and the second buckle plate 2 are respectively sleeved and pushed from both sides of the steel structure cross beam 3, the slider 5 is inserted into the guiding groove 4. With the pushing, the screw rod 7 passes through the perforation 6, and after being exposed, the nut 8 is screwed on and locked. After locking, the first buckle plate 1 and the second buckle plate 2 tightly clamp the steel structure cross beam 3 through the rubber gasket 10 (located in the embedding groove 9 and elastically deformed under pressure), preventing side slip.

[0038] Working of the assembly limiting part: During the pushing process, the elastic hanging plate 12 is aligned with the corresponding side groove 11. The top plate of the first buckle plate 1 squeezes and pushes along the inclined surface of the clamping strip 13, deforming the elastic hanging plate 12. When the clamping strip 13 passes over the side groove 11, the elastic hanging plate 12 rebounds, and the clamping strip 13 is stuck on the top plate of the first buckle plate 1 to achieve top limiting. During disassembly, pinch the pull ring 14 to tension and deform the elastic hanging plate 12, so that the clamping strip 13 is not blocked by the top plate of the first buckle plate 1, and then push out the elastic hanging plate 12.

[0039] Working of the hoisting part: When the first buckle plate 1 and the second buckle plate 2 are fixed, the two lifting tools 15 are misaligned and spliced through the assembly groove 16. The reserved holes 17 are opposite, and the hoisting rope body or hook is passed through the reserved holes 17 and the reinforcement collar 18 for hoisting work.

[0040] Through the above working principle, the steel structure lifting and fixing device of the present invention can effectively fix the steel structure cross beam 3, prevent side slip or falling off during the hoisting process, and at the same time facilitate the hoisting operation through the hoisting part.

[0041] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
