Description

Technical Field

[0001] This utility model belongs to the field of building engineering technology, and in particular relates to an auxiliary mechanism for overall lifting deformation control of large-span steel structures. Background Technology

[0002] As modern buildings and industrial facilities develop towards larger spans and higher precision, large-span steel structures are widely used in various projects, such as large stadiums, airport terminals, and bridges. Due to their large weight and long span, large-span steel structures face many challenges during installation and construction.

[0003] During the lifting process of steel structure, due to the uneven distribution of lifting points in various parts of the steel structure, some parts are greatly affected by their own weight, resulting in overall deformation. Therefore, we propose an auxiliary mechanism for controlling the overall lifting deformation of large-span steel structures. Utility Model Content

[0004] The purpose of this utility model is to provide an auxiliary mechanism for controlling the deformation of a large-span steel structure during overall lifting. The support block provides support force to prevent deformation of the part that exceeds the fixed plate. The fixed plate is manually pulled to move the slider in the groove, thereby moving the support block. This allows the support block to provide support for the excessively long part of the steel structure, thus solving the problem of overall deformation during the lifting process of the steel structure.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is an auxiliary mechanism for controlling the deformation of a large-span steel structure during overall lifting, including a support frame, an anti-deformation mechanism on the outer wall of the support frame, and a fixing mechanism on the top of the support frame;

[0007] The anti-deformation mechanism includes a motor fixedly connected to the outer wall of the bracket. The output shaft of the motor is fixedly connected to a rotating shaft via a coupling. A gear is fixedly connected to the outer wall of the rotating shaft. A gear rack meshes with the outer wall of the gear. A fixing block is fixedly connected to the top of the gear rack. A connecting block is fixedly connected to the outer wall of the gear rack. A connecting column is fixedly connected to the inner wall of the connecting block. A support block one is fixedly connected to the end of the connecting column away from the connecting block. A fixing plate is fixedly connected to the outer wall of the connecting block. A support plate is fixedly connected to the top of the fixing plate. A sliding groove is formed inside the support plate. A slider is slidably connected to the inner wall of the sliding groove. A fixing block two is slidably connected to the end of the slider away from the sliding groove. A support plate two is fixedly connected to the top of the fixing block two. A support block two is fixedly connected to the top of the support plate two. A connecting column two is fixedly connected to the outer wall of the support block two.

[0008] Furthermore, the outer wall of the rotating shaft is rotatably connected to the inner wall of the bracket, and the outer wall of the gear rack is slidably connected to the inner wall of the bracket.

[0009] Furthermore, the outer wall of the support plate is fixedly connected to the outer wall of the support block one, and the end of the connecting column two away from the support block two is fixedly connected to the outer wall of the fixing block two.

[0010] Furthermore, the fixing mechanism includes a second fixing plate fixedly connected to the outer wall of the fixing block, a fixing frame fixedly connected to the outer wall of the second fixing plate, and a telescopic rod fixedly connected to the inner wall of the fixing frame.

[0011] Furthermore, a limiting plate is fixedly connected to the outer wall of the telescopic rod, and a spring is fixedly connected to the side of the limiting plate near the telescopic rod. The end of the spring away from the limiting plate is fixedly connected to the inner wall of the fixed frame.

[0012] Furthermore, the telescopic rod is located inside the spring, and the second fixed plate has a second sliding groove inside, with a clamping plate slidably connected inside the second sliding groove.

[0013] Furthermore, the inner wall of the clamping plate is threaded with a reverse threaded rod, and the outer wall of the reverse threaded rod is fixedly connected with a worm gear.

[0014] Furthermore, a fixing block three is fixedly connected to the outer wall of the fixing frame, and a worm is rotatably connected to the inner wall of the fixing block three, with the outer wall of the worm meshing with the outer wall of the worm wheel.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model, by setting up support block one and support block two, starts a motor to drive the rotating shaft to rotate. When the rotating shaft rotates, it drives the gear to rotate, and when the gear rotates, it drives the gear rack to move, thereby lifting the fixed block. The part of the steel structure that exceeds the fixed plate two is supported by support block one to prevent deformation of the part exceeding the fixed plate two. The support plate and connecting column provide support for support block one. When the steel structure is too long, the fixed block two is manually pulled to move the slider in the slide groove, thereby moving the support plate two, and then moving the support block two, so that the support block two provides support for the part of the steel structure that is too long. When the length of the steel structure is still too long, extra fixed blocks two can be installed to continue to provide support for the excessively long steel structure. This mechanism can prevent the suspended part of the steel structure from deforming when it is lifted, effectively ensuring the stability and safety of the steel structure during lifting.

[0017] 2. This utility model, by setting a reverse threaded rod, first places the steel structure above the second fixed plate and below the limiting plate, which will drive the limiting plate to move upward. As the limiting plate moves, it will compress the spring and the telescopic rod. The reaction force provided by the spring will also compress the limiting plate, thereby compressing the steel structure. Then, the worm gear is manually rotated, which drives the worm wheel to rotate. As the worm wheel rotates, it drives the reverse threaded rod to rotate, thereby causing the two clamping plates to move closer together and clamp the steel structure. This mechanism can fix the steel structure above the second fixed plate, preventing the steel structure from shaking during the lifting process and causing deformation.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0028] Please see Figure 1-5As shown, this utility model is an auxiliary mechanism for controlling the deformation of a large-span steel structure during overall lifting. It includes a support 101, an anti-deformation mechanism 2 on the outer wall of the support 101, and a fixing mechanism 3 on the top of the support 101. The anti-deformation mechanism 2 includes a motor 201 fixedly connected to the outer wall of the support 101. The motor 201 drives a rotating shaft 202 to rotate. The output shaft of the motor 201 is fixedly connected to the rotating shaft 202 via a coupling. A gear 203 is fixedly connected to the outer wall of the rotating shaft 202. A gear rack 204 meshes with the outer wall of 203. A fixing block 205 is fixedly connected to the top of the gear rack 204. By setting the gear rack 204, when the gear rack 204 rises, it will drive the fixing block 205 to rise together. A connecting block 206 is fixedly connected to the outer wall of the gear rack 204. A connecting post 207 is fixedly connected to the inner wall of the connecting block 206. A support block 208 is fixedly connected to the end of the connecting post 207 away from the connecting block 206. A fixing plate 209 is fixedly connected to the outer wall of the connecting block 206. By setting the support block... 208. Support plate 210 is fixedly connected to the top of fixed plate 209, and a groove 211 is formed inside the support plate 210. A slider 212 is slidably connected to the inner wall of the groove 211. A fixed block 213 is slidably connected to the end of the slider 212 away from the groove 211. The fixed block 213 provides support for the support block 215. A support plate 214 is fixedly connected to the top of the fixed block 213. A second support block 215 is fixedly connected, and a second connecting column 216 is fixedly connected to the outer wall of the second support block 215. The outer wall of the rotating shaft 202 is rotatably connected to the inner wall of the bracket 101. By setting the second support block 215, the steel structure extending beyond the second fixed plate 301 is supported. The outer wall of the gear rack 204 is slidably connected to the inner wall of the bracket 101. The outer wall of the support plate 210 is fixedly connected to the outer wall of the first support block 208. The end of the second connecting column 216 away from the second support block 215 is fixedly connected to the outer wall of the second fixed block 213.

[0029] The fixing mechanism 3 includes a fixing plate 301 fixedly connected to the outer wall of the fixing block 205. A fixing frame 302 is fixedly connected to the outer wall of the fixing plate 301. A telescopic rod 303 is fixedly connected to the inner wall of the fixing frame 302. A limit plate 305 is fixedly connected to the outer wall of the telescopic rod 303. By setting the limit plate 305, the steel structure is compressed. A spring 304 is fixedly connected to the side of the limit plate 305 near the telescopic rod 303. The end of the spring 304 away from the limit plate 305 is fixedly connected to the inner wall of the fixing frame 302. The telescopic rod 303 is located inside the spring 304. A sliding groove 306 is provided inside the fixing plate 301. By setting the sliding groove 306, the clamping plate 307 can slide in the sliding groove 306. The clamping plate 307 is slidably connected inside the sliding groove 306.

[0030] The inner wall of the clamping plate 307 is threaded with a reverse threaded rod 308, and the outer wall of the reverse threaded rod 308 is fixedly connected with a worm gear 309. The outer wall of the fixing frame 302 is fixedly connected with a fixing block 310, and the inner wall of the fixing block 310 is rotatably connected with a worm 311. By setting the worm 311, the worm gear 309 is driven to rotate, and the outer wall of the worm 311 meshes with the outer wall of the worm gear 309.

[0031] One specific application of this embodiment is:

[0032] First, the steel structure is placed above the fixed plate 301 and below the limiting plate 305. This causes the limiting plate 305 to move upwards. As the limiting plate 305 moves, it compresses the spring 304 and the telescopic rod 303. The reaction force provided by the spring 304 further compresses the limiting plate 305, thus compressing the steel structure. Then, the worm gear 311 is manually rotated, causing the worm wheel 309 to rotate. Simultaneously, the worm wheel 309 rotates, causing the reverse threaded rod 308 to rotate, thereby bringing the two clamping plates 307 closer together to clamp the steel structure. This mechanism secures the steel structure above the fixed plate 301, preventing swaying and deformation during lifting. Then, the motor 201 is started, driving the rotating shaft 202 to rotate. Simultaneously, the rotating shaft 202 rotates, driving the gear 203 to rotate. As gear 203 rotates, it drives rack 204 to move, thereby lifting fixed block 205. The portion of the steel structure that extends beyond fixed plate 201 is supported by support block 208 to prevent deformation. Support plate 210 and connecting column 207 provide support to support block 208. When the steel structure is too long, manually pulling fixed block 213 causes slider 212 to slide in groove 211, thereby moving support plate 214 and then support block 215, providing support for the excessively long portion of the steel structure. If the steel structure is still too long, additional fixed blocks 213 can be added to continue supporting it. This mechanism prevents deformation of the suspended portion of the steel structure during lifting, effectively ensuring the stability and safety of the steel structure during lifting.
