Description

Technical Field

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

[0002] In modern construction engineering, modular construction has become an important development direction for steel structure applications due to its advantages of high efficiency, precision, and environmental friendliness. The efficiency of modular production and on-site installation of steel structures directly determines the overall construction progress and quality. The hoisting and positioning process, as a key step in the transfer of modular steel structures from factory prefabrication to on-site assembly, is the core technical support for ensuring the construction effect of modular steel structures and has a significant impact on the safety and economy of construction projects.

[0003] Currently, the equipment used for steel structure hoisting and positioning mainly consists of a support base as the basic frame, with a hanging structure at the top of the base for connecting the hoisting equipment, and is also equipped with fixing plates. Its working principle is as follows: the equipment is fixed to a designated position on the construction platform or ground via the support components at the bottom of the base, and then the hoisting equipment is used to move the entire device and the steel structure module to be hoisted. After the steel structure module is placed on the base, the temporary fixing structure is mostly a bolted fixing plate. After the steel structure is adjusted to the target position, the fixing plate is connected to the steel structure and surrounding fixing bases to achieve temporary fixation of the steel structure.

[0004] In actual operation, existing equipment encounters various steel structures with differing dimensions and shapes, requiring different temporary fixing locations and specifications of fixing plates. When hoisting and positioning steel structures of different sizes, operators must first select a matching fixing plate based on the specific dimensions of the steel structure, and then manually install the fixing plate at the preset fixing points. Simultaneously, they must ensure the fit between the fixing plate and the steel structure and surrounding fixing bases to guarantee the stability of the temporary fixation. This process not only consumes significant manpower and time but is also prone to operational errors during manual installation, leading to insufficient tightness between the fixing plate and the steel structure, thus affecting the temporary fixation effect and increasing the risk of displacement of the steel structure during subsequent construction. Therefore, a modular steel structure hoisting and positioning device is proposed to address these issues. Utility Model Content

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0038] A modular steel structure hoisting and positioning device, referring to Figure 1 , Figure 2 and Figure 4 It includes a base plate 1, a clamping and positioning mechanism 2 installed at the top of the base plate 1, a hoisting and connecting mechanism 3 installed at the top of the base plate 1, and a fixing and supporting mechanism 4 installed at the bottom of the base plate 1.

[0039] The clamping and positioning mechanism 2 includes a fixed plate 21, the bottom end of which is fixedly connected to the top end of the base plate 1, serving as a reference component for clamping and positioning and providing stable support for clamping. Two support plates 22 are fixedly connected to the rear end of the fixed plate 21, symmetrically distributed to further enhance the structural stability of the fixed plate 21. A pair of buffer components 23 are provided at the front end of the fixed plate 21 to reduce hard impacts when clamping steel structures. Two guide rails 24 are fixedly connected inside the base plate 1, and sliding plates 25 are slidably connected to the outside of the two guide rails 24. To guide the movement of the sliding plate 25, another pair of buffer components 23 are provided at the rear end of the sliding plate 25, which cooperate with the buffer components 23 on the fixed plate 21 to form bidirectional buffer protection. A motor 26 is fixedly connected to the top of the base plate 1. The motor 26 provides a power source for the adjustment of the clamping and positioning mechanism 2. A screw 27 is fixedly connected to the drive end of the motor 26. When the motor 26 is running, it can directly drive the screw 27 to rotate synchronously. A ball nut 28 is rotatably connected to the outside of the screw 27. When the screw 27 rotates, it can drive the ball nut 28 to move along the axial direction of the screw 27.

[0040] The buffer assembly 23 includes a rotating shaft 231, which is externally fixedly connected to the front end of the fixed plate 21, providing axial support for the rotation of the buffer plate 232. The buffer plate 232 is rotatably connected to the external side of the rotating shaft 231. The buffer plate 232 can rotate around the rotating shaft 231 to adapt to the surface shape of the steel structure. A spring 233 is fixedly connected to the bottom end of the buffer plate 232 to provide elastic restoring force for the buffer plate 232. The hoisting connection mechanism 3 includes four telescopic rods 31. The bottom ends of the four telescopic rods 31 are all threadedly connected to the top end of the base plate 1. The four telescopic rods 31 are distributed at the four corners of the base plate 1. The threaded connection method facilitates the disassembly, assembly, and maintenance of the telescopic rods 31. A lifting lug plate 32 is fixedly connected to the top end of the telescopic rod 31. The lifting lug plate 32 provides a reliable force point for the connection of the rope 33. A rope 33 is fixedly connected to the top end of the lifting lug plate 32. A hook 34 is sleeved on the top end of the rope 33 for connecting with external hoisting equipment to achieve overall hoisting.

[0041] The bottom end of the support plate 22 is fixedly connected to the top end of the base plate 1. The double fixation further enhances the connection strength between the fixed plate 21 and the base plate 1. The rear end of the spring 233 is fixedly connected to the front end of the fixed plate 21, so that the spring 233 can maintain stable elastic support when the buffer plate 232 rotates. The base plate 1 has a sliding groove inside, and the sliding plate 25 is slidably connected inside the sliding groove. The sliding groove and the guide rail 24 cooperate to provide a more stable moving space for the sliding plate 25. The rear end of the screw 27 is rotatably connected to the inside of the base plate 1. The base plate 1 provides rear end support for the screw 27 to ensure its rotation stability. The outside of the screw 27 is rotatably connected to the inside of the sliding plate 25. The rear end of the ball nut 28 is fixedly connected to the front end of the sliding plate 25. When the ball nut 28 moves, it can directly drive the sliding plate 25 to move synchronously.

[0042] Specifically, when clamping and positioning the steel structure is required, the motor 26 starts and drives the screw 27 to rotate. The rotation of the screw 27 is converted into the axial movement of the ball nut 28, which in turn drives the sliding plate 25 to move along the guide rail 24. During this process, the buffer assembly 23 at the rear end of the sliding plate 25 and the buffer assembly 23 at the front end of the fixed plate 21 will first contact the surface of the steel structure. The buffer plate 232 rotates around the pivot 231 and compresses the spring 233. The elasticity of the spring 233 alleviates the clamping impact force and adapts to the subtle morphological differences on the surface of the steel structure, ultimately achieving a stable and gentle clamping and positioning of the steel structure.

[0043] Reference Figure 1 and Figure 3The fixed support mechanism 4 includes a base 41, which serves as the core load-bearing support component and bears the load transmitted by the base plate 1. The top of the base 41 is threaded to the bottom of the base plate 1, which facilitates the quick assembly and disassembly of the base 41 and the base plate 1. Two diagonal braces 42 are fixedly connected to the bottom of the base 41. The triangular support structure formed by the diagonal braces 42 enhances the anti-tipping ability of the base 41. A connecting plate 43 is fixedly connected to the bottom of the two diagonal braces 42. The connecting plate 43 is in direct contact with the fixing point for fixed installation. Bolts 44 are threaded to the four corners of the connecting plate 43. The bolts 44 distributed at the four corners can achieve uniform fixation of the connecting plate 43. The top of the connecting plate 43 is fixedly connected to the bottom of the base 41. Through the double connection with the base 41, the stability of the overall structure is improved.

[0044] Specifically, the base 41 is tightly fixed to the bottom plate 1 via a threaded connection at its top, transferring the weight load of the bottom plate 1 and the steel structure above it to itself. Through the cooperation of the connecting plate 43 and the diagonal brace 42, the base 41 provides stable bottom support. The coordinated action of each component forms a complete force transmission path, ensuring the stability of the entire device and steel structure, and providing a safe and reliable support foundation for subsequent construction operations.

[0045] The implementation principle of this application embodiment is as follows: When in use, the steel structure is fixed by activating the clamping and positioning mechanism 2. The motor 26 drives the screw 27 to rotate, and the ball nut 28 converts the rotational motion into axial movement, which drives the sliding plate 25 to move closer to the fixed plate 21 along the guide rail 24 and the slide groove of the base plate 1. During the process, the sliding plate 25 and the buffer assembly 23 on the fixed plate 21 first contact the steel structure. The buffer plate 232 rotates around the rotating shaft 231 and compresses the spring 233, which not only relieves the clamping impact force, but also adapts to the shape of the component, and finally achieves stable clamping of the steel structure. The support plate 22 helps to enhance the stability of the fixed plate 21.

[0046] The hoisting operation is then completed through the hoisting connection mechanism 3. According to the center of gravity and height of the steel structure, the lengths of the four telescopic rods 31 at the top of the base plate 1 are adjusted so that the lifting lug plate 32 is in a horizontal stress state. The external hoisting equipment connects the rope 33 through the hook 34 to drive the clamped and fixed steel structure to be lifted smoothly.

[0047] Finally, the device foundation is fixed using the fixed support mechanism 4. The connecting plate 43 is placed on the side of the construction platform and secured with four-corner bolts 44. The base 41, through its fixation to the connecting plate 43 and the triangular support of the diagonal brace 42, forms a stable support foundation. Simultaneously, the base 41 is threadedly connected to the base plate 1, thus connecting the fixed support mechanism 4 with the main body of the device. Throughout the process, the three mechanisms work in concert to ensure precise positioning, stable hoisting, and reliable support, achieving efficient installation of the modular steel structure.

[0048] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
