Description

Technical Field

[0001] This utility model relates to the field of steel structure hoisting technology, and in particular to steel structure hoisting clamps. Background Technology

[0002] Steel structure hoisting clamps are connecting tools specifically designed for hoisting operations of steel structure components. These clamps are widely used in various steel structure engineering fields, and the reliability of hoisting clamps is directly related to construction safety, work efficiency, and installation accuracy.

[0003] Traditional steel structure hoisting clamps consist of four basic parts: lifting rings, fixed clamping arms, adjusting bolts, and anti-slip pads. A lifting hole is located at the top. The fixed clamping arms are made of high-strength steel plates, cut and welded together. A fixed-width clamping cavity is formed between the two clamping arms. The adjusting bolts pass through threaded holes on both sides of the clamping arms. The clamping clamp model must be selected to match the cross-sectional dimensions of the component to be hoisted. The clamping cavity of the clamping arm is aligned with the preset clamping position on the component. The adjusting bolts on both sides are rotated one by one with a wrench to observe the connection status between the clamp and the component. Traditional clamps have fixed clamping cavity dimensions, increasing equipment procurement costs. The adjusting bolts rely on manual tightening, and uneven manual force application can lead to imbalance in the force on both sides of the clamping arms, increasing the risk of high-altitude operations. The fixed clamping arms cannot adapt to non-standard cross-section components, causing the component to sway during hoisting.

[0004] To address the issues of low operating efficiency and poor fastening reliability of traditional clamps, existing technologies have made some improvements, replacing manual fastening bolts with hydraulic drive devices. These devices use hydraulic cylinders to push the clamping arms for automatic clamping, significantly shortening fastening time and ensuring uniform clamping force. Some improvements also include replaceable wear-resistant liners on the inner side of the clamping arms to extend clamp life and adapt to components with different surface hardness. However, existing improvements still fail to solve the core technical pain point of the fixed clamp spacing. Because the clamping arm spacing is fixed, when switching to hoist components of different sizes, the machine must be stopped to replace the corresponding clamp model, directly reducing overall construction efficiency. If the construction site does not have all the required clamp models, the construction party is forced to temporarily purchase or fabricate clamps. The lack of an adjustable spacing mechanism means that the relative distance between the clamping arms cannot be flexibly adjusted according to the component size, requiring the replacement of the entire clamp set for adaptation, thus increasing equipment investment and management costs. Utility Model Content

[0035] Specifically, in the steel structure hoisting fixture, the rotating mechanism 3 at the top of the main board 1 cooperates with the main board 1 to adjust the angles of the main board 1, the sliding mechanism 2 below, the fixing plate 5, and the quick-release assembly 4. The sliding mechanism 2 at the bottom of the main board 1 cooperates with the main board 1 to adjust the clamp spacing to accommodate components of different specifications. The fixing plates 5 on the left and right sides at the bottom of the sliding mechanism 2 cooperate with the sliding mechanism 2 to provide installation support for the quick-release assembly 4. The quick-release assembly 4 at the bottom of the two fixing plates 5 cooperates with the fixing plates 5 to facilitate quick replacement of different types of clamping components to accommodate various components. Inside the sliding mechanism 2, the guide rail 201 is fixed to the middle of the bottom side of the main board 1 and slides in cooperation with the slide groove 202 at the top of the slider 205 to provide sliding guidance for the slider 205. The limiting plates 204 on the left and right sides at the bottom of the main board 1 are fixedly connected to the main board 1, which limits the slider 205. The 05-stroke travel is rotatably connected to the bidirectional threaded rod 203 to support it. The bidirectional threaded rod 203 is rotatably connected to the two limit plates 204, and its left and right sides are threadedly connected to the slider 205, converting the power of the motor 206 into the linear movement force of the slider 205, driving the slider 205 and the lower fixed plate 5 and quick-release assembly 4 to move synchronously to adjust the spacing. The connecting groove 207 on the left side of the bidirectional threaded rod 203 is slidably connected to the right side of the motor 206, realizing the power transmission between the motor 206 and the bidirectional threaded rod 203.

[0036] Reference Figure 1 , Figure 2 and Figure 3 The rotating mechanism 3 includes a housing 301, which provides a protective space for the internal components of the rotating mechanism 3. The housing 301 is rotatably connected to the top center of the main board 1, and the connection method is used to enable the main board 1 to rotate flexibly relative to the housing 301. A lifting ring 302 is fixedly connected to the top of the housing 301, and the lifting ring 302 is used to connect with the lifting equipment to suspend the entire lifting clamp. A second motor 305 is fixedly connected to the top of the inner wall of the housing 301, and the second motor 305 is used to provide a power source for the operation of the rotating mechanism 3. A second gear 304 is fixedly connected to the bottom of the second motor 305, and the second gear 304 is used to transmit the power of the second motor 305 to the first gear 303. The second gear 304 and the first gear 303 are meshed and connected, and the meshing connection method is used to achieve stable power transmission to drive the first gear 303 to rotate. The bottom end of the first gear 303 is fixedly connected to the top of the main board 1, and the fixed connection method is used to make the rotation of the first gear 303 synchronously drive the main board 1 and the components below to rotate to achieve angle adjustment.

[0037] Specifically, in the rotating mechanism 3, the outer shell 301 serves as a basic component, providing installation and protective space for the second motor 305, the second gear 304, and the first gear 303 inside the rotating mechanism 3. The top center of the main board 1 is rotatably connected to the outer shell 301. This connection allows the main board 1 to rotate flexibly relative to the outer shell 301, laying the foundation for subsequent angle adjustment. The top of the outer shell 301 is fixedly connected to the lifting ring 302. The lifting ring 302, through connection with the lifting equipment, suspends the entire lifting clamp, providing support for the lifting operation. The top of the inner wall of the outer shell 301 is fixedly connected to the second motor 305. The second motor 305 provides the power source for the operation of the rotating mechanism 3. The bottom of the second motor 305... The first gear is fixedly connected to the second gear 304. The second gear 304 receives the power output from the second motor 305 and transmits the power to the first gear 303. The second gear 304 and the first gear 303 are meshed together. This meshing connection ensures stable power transmission, so that when the second gear 304 rotates, it can drive the first gear 303 to rotate synchronously. The bottom end of the first gear 303 is fixedly connected to the top of the main board 1. This fixed connection allows the first gear 303 to rotate synchronously and drive the main board 1, thereby driving the sliding mechanism 2, the fixed plate 5, and the quick-release assembly 4 below the main board 1 to rotate together. Finally, the angle adjustment function of the entire clamp is realized to meet the hoisting adaptation requirements of steel structure components with different placement angles.

[0038] Reference Figure 1 , Figure 4 and Figure 6A protective shell 7 is located on the bottom left side of the motherboard 1. This protective shell 7 protects the motor 206 located below the motherboard 1 from external impurities affecting the operation of the component. Guide rails 8 are fixedly connected to the front and rear sides of the top of the protective shell 7. These guide rails 8 cooperate with sliding grooves 9 to achieve sliding adjustment of the protective shell 7. Sliding grooves 9 are provided on the left and right sides of the bottom of the motherboard 1. These sliding grooves 9 provide sliding channels for the guide rails 8. The two guide rails 8 are slidably connected to their corresponding sliding grooves 9. This sliding connection method is used to adjust the position of the protective shell 7 relative to the motherboard 1 to adapt to different body shapes. To meet different protection requirements, infrared rangefinders 6 are fixedly connected to adjacent sides of the two fixed plates 5. These rangefinders 6 are used to monitor the distance between the two fixed plates 5 in real time. The two infrared rangefinders 6 are electrically connected to each other to achieve data synchronization and calibration, thereby improving distance detection accuracy. The quick-release assembly 4 includes a sliding plate 402, which provides a mounting carrier for other components of the quick-release assembly 4. Sliding plates 402 are located at the bottom of the two fixed plates 5, and each sliding plate 402 has a groove 406 on its inner wall. The second slide groove 406 provides sliding guidance for the support plate 401. Support plates 401 are slidably connected to the front and rear sides of the inner walls of both slide grooves 406. These support plates 401 connect the fixed plate 5 and the clamping plate 404 and allow for angle adjustment. The tops of the multiple support plates 401 are rotatably connected to the inner wall of the fixed plate 5. This rotatable connection allows for angle adjustment of the support plates 401 relative to the fixed plate 5 to accommodate different clamping requirements. Bolts 403 are slidably connected to the front and rear sides of the outer walls of both slide plates 402. These bolts 403 are used to connect the clamping plate 404 and the support plate 404. For the fixed connection of 01, clamping plates 404 are slidably connected to the front and rear sides of the outer walls of the two sliding plates 402. The clamping plates 404 are used to install clamping blocks 405 and transmit clamping force. Multiple bolts 403 pass through the top of the corresponding clamping plates 404 and the bottom of the support plates 401 and are threaded together. This threaded connection is used to achieve a stable fixation between the clamping plates 404 and the support plates 401 by tightening the bolts 403. Clamping blocks 405 are fixedly connected to adjacent sides of the multiple clamping plates 404. The clamping blocks 405 are used to directly contact the steel structure components to increase friction and ensure stable clamping.

[0039] Specifically, the protective shell 7 on the bottom left of the motherboard 1 has guide rails 8 on its top front and rear sides that are slidably connected to the sliding grooves 9 on the bottom left and right sides of the motherboard 1. This connection enables the installation and sliding adjustment of the protective shell 7 on the bottom of the motherboard 1, providing protection for the components below. The infrared rangefinders 6 on the adjacent sides of the two fixing plates 5 are electrically connected. This connection is used to detect the distance between the two fixing plates 5 in real time, providing data reference for the sliding mechanism 2 to adjust the distance. In the quick-release assembly 4, the sliding plate 402 at the bottom of the fixing plate 5 provides an installation base for the internal components of the assembly. The sliding groove 406 on the inner wall of the sliding plate 402 is slidably connected to the front and rear sides of the support plate 401. The top of the support plate 401 is connected to the sliding groove 9 on the bottom left of the motherboard 1. The inner wall of the fixed plate 5 is rotatably connected, which enables the sliding and rotational adjustment of the support plate 401. The bolts 403 on the front and rear sides of the outer wall of the slide plate 402 pass through the top of the corresponding clamping plate 404 and the bottom of the support plate 401 and are threaded together. This fit fixes the clamping plate 404 to the support plate 401, thereby fixing the position of the clamping plate 404. The clamping block 405 on the adjacent side of the clamping plate 404 is used to directly contact the steel structure component after the clamping plate 404 is fixed, so as to clamp and fix the component. Each newly added component, through the above fit, realizes the functions of protection, spacing detection, clamping component adjustment and fixing, and helps to improve the safety and adaptability of the fixture.

[0040] Reference Figure 1 , Figure 2 and Figure 6 Anti-collision sleeves 10 are fixedly connected to the front and rear sides of both sliding plates 402. These anti-collision sleeves 10 are used to prevent the sliding plates 402 from directly colliding with other components and causing damage during movement or hoisting operations. All anti-collision sleeves 10 are rounded to eliminate sharp edges and prevent scratches to operators or snagging on components during operation. Anti-slip pads 11 are fixedly connected to the tops of multiple clamping blocks 405. These anti-slip pads 11 increase the friction between the clamping blocks 405 and the steel structure components, preventing damage during clamping. During the process of sliding, the top of each of the multiple anti-slip pads 11 is fixedly connected with a protrusion 12. The protrusion 12 is used to further enhance the anti-slip effect of the anti-slip pad 11 and improve the stability of friction by increasing the pressure at the contact point. The bottom of each of the multiple clamping blocks 405 is provided with a circular groove 14. The circular groove 14 is used to provide installation space for the buffer block 13. The bottom of each of the multiple circular grooves 14 is fixedly connected with a buffer block 13. The buffer block 13 is used to absorb the impact force when clamping the component and avoid rigid contact between the clamping block 405 and the component, which may cause damage to the surface of the component or deformation of the clamping block 405.

[0041] Specifically, the front and rear sides of the two sliding plates 402 are fixedly connected to the anti-collision sleeves 10. During the movement or hoisting operation of the sliding plates 402, the anti-collision sleeves 10 prevent direct collisions between the sliding plates 402 and other components, thus avoiding damage. The rounded edges of the anti-collision sleeves 10 eliminate surface sharp corners, preventing scratches to operators or snagging on components during operation. Together, these two components provide collision protection for the sliding plates 402 and ensure operational safety. The tops of multiple clamping blocks 405 are fixedly connected to anti-slip pads 11. The anti-slip pads 11 increase the friction between the clamping blocks 405 and the steel structure components, preventing slippage during component clamping. The tops of the anti-slip pads 11 are fixedly connected to protrusions 12. The protrusions 12 further enhance the anti-slip effect of the anti-slip pads 11 by increasing the contact point pressure. To enhance frictional stability, the three components work together to achieve stable clamping of the components and prevent slippage risks. Multiple clamping blocks 405 have circular grooves 14 at their bottoms, which provide installation space for buffer blocks 13. The bottom of the circular grooves 14 is fixedly connected to the buffer blocks 13. The buffer blocks 13 absorb impact forces when clamping the components, preventing rigid contact between the clamping blocks 405 and the components, which could lead to surface damage or deformation of the clamping blocks 405. The three components work together to achieve impact buffering and protection of the components and parts during the clamping process. Through the above-mentioned cooperation, each component plays a role in three dimensions: collision protection, anti-slip stability, and impact buffering, which together improve the safety, clamping stability, and protection of the components and its own parts during steel structure hoisting clamping operations.

[0042] Working Principle: The core function of the sliding mechanism 2 is to achieve flexible adjustment of the clamp spacing, thereby solving the problem of fixed clamp spacing in the existing technology, which cannot adapt to steel structure components of different specifications. When it is necessary to adjust the clamp spacing according to the size of the steel structure component to be hoisted, the motor 206 is started. The motor 206 transmits power to the bidirectional threaded rod 203 through a fixed connection with the left end connecting groove 207 of the bidirectional threaded rod 203, causing the bidirectional threaded rod 203 to rotate around its own axis. The left and right sides of the bidirectional threaded rod 203 are respectively threadedly connected to two sliders 205, and the threads on the left and right sides of the bidirectional threaded rod 203 have opposite directions of rotation. During its rotation, it will generate axial driving forces in opposite directions on the two sliders 205. If the bidirectional threaded rod 203 rotates clockwise, the left slider 205 will move to the right along the threaded rod, and the right slider 205 will move to the left along the threaded rod. If the bidirectional threaded rod 203 rotates counterclockwise... The two sliders 205 will separate in opposite directions, thereby achieving relative proximity or distance between the two sliders 205. The groove 202 opened in the middle of the top side of the slider 205 forms a sliding fit with the guide rail 201 fixed in the middle of the bottom side of the main board 1. The guide rail 201 provides a stable sliding guide for the slider 205. The slider 205 can move along the length of the guide rail 201 to ensure the accuracy of the spacing adjustment. The limiting plate 204 set on the left and right sides of the bottom of the main board 1 plays a dual role. The limiting plate 204 is threaded to the left and right sides of the bidirectional threaded rod 203, supporting and fixing the two ends of the bidirectional threaded rod 203 to prevent radial runout of the bidirectional threaded rod 203 when rotating at high speed, ensuring transmission stability. The limiting plate 204 can limit the maximum travel of the slider 205 by its own position, preventing the two sliders 205 from detaching from the bidirectional threaded rod 203 due to excessive proximity or separation, and ensuring the safe operation of the mechanism.

[0043] Furthermore, the core function of the rotating mechanism 3 is to enable the flexible rotation of the main board 1 and the sliding mechanism 2 below it, providing an appropriate angle for the sliding mechanism 2 to adjust the clamp spacing. A housing 301 is rotatably connected to the top center of the main board 1, and a lifting ring 302 is fixedly connected to the top of the housing 301. The lifting ring 302 is used to connect with lifting equipment, providing suspension support for the entire lifting clamp. A second motor 305 is fixedly connected to the top of the inner wall of the housing 301, and a second gear 304 is rotatably connected to the bottom of the second motor 305. The second gear 304 meshes with a first gear 303, and the bottom end of the first gear 303 is fixedly connected to the top of the main board 1, forming a complete power transmission and rotation drive structure. When the sliding mechanism 2 needs to adjust the clamp spacing according to the size of the steel structure component to be lifted, if there is a deviation between the component placement angle and the initial clamp angle, the second motor 305 will be activated. Motor 2 305 drives gear 2 304 at the bottom to rotate around its own axis. Gear 2 304 meshes with gear 1 303. The rotation of gear 2 304 drives gear 1 303 to rotate synchronously. Since the bottom end of gear 1 303 is fixedly connected to the main board 1, the rotation of gear 1 303 drives the main board 1 to rotate around the rotation connection point between the outer shell 301 and the main board 1. This, in turn, drives the sliding mechanism 2 and the clamp below the main board 1 to rotate synchronously. By controlling the rotation direction and speed of motor 2 305, the angle of the main board 1 and the clamp can be adjusted, so that the clamp after the spacing of the sliding mechanism 2 is adjusted can be accurately aligned with the clamping position of the component. This optimizes the adaptability of the clamp to components of different specifications and different placement angles. From the perspective of angle adjustment, it helps to solve the problem of the same clamp spacing and poor adaptability in the existing technology, and improves the flexibility and accuracy of hoisting operations.
