Description

Technical Field

[0001] This utility model relates to the field of hoisting technology for irregular building structures, specifically a hoisting device for irregular building structures. Background Technology

[0002] Lifting refers to the general term for the placement, connection, and installation of equipment, workpieces, etc., using cranes or lifting equipment. In the construction process, after a building is erected to a certain height, lifting equipment is needed to hoist prefabricated building components to facilitate the next round of assembly.

[0003] Besides common building components, there are also many irregularly shaped building components. Most traditional hoisting devices are rigid clamping structures with a narrow range of applications. Special tools need to be designed specifically for these irregular structures, which not only increases the initial preparation and equipment investment costs but also reduces the efficiency of hoisting operations. At the same time, when hoisting irregular building structures, common hoisting equipment is not very effective because the force points of the hoisting equipment are relatively singular, making it difficult to keep the irregular building components stable and resulting in poor overall flexibility.

[0004] Therefore, this application proposes a hoisting device for irregular building structures in order to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this utility model is to provide a hoisting device for irregular building structures, so as to solve the problems mentioned in the background art that the existing devices are difficult to adapt to irregular building structures and are unstable during hoisting.

[0006] This utility model provides the following technical solution: a hoisting device for irregular building structures, including a base plate, on which a hoisting assembly is provided. The hoisting assembly includes multiple electric push rods fixed to the top surface of the base plate, and mounting seats fixed to the top surfaces of the multiple electric push rods. The mounting seats have mounting holes, and ropes are installed in the mounting holes. Lifting rings are installed on the ropes. Multiple L-shaped plates are fixed to the bottom surface of the base plate, and a base plate is fixed to the bottom surface of the multiple L-shaped plates. A clamping assembly is installed between the base plate and the base plate. The clamping assembly includes a toothed plate slidably connected to the top surface of the base plate. A connecting rod is fixed to the end side of the toothed plate, and a mounting box is fixed to the side wall of the connecting rod. An elastic clamping member is installed inside the mounting box.

[0007] Preferably, a plurality of electric actuators are fixed on the top surface of the substrate, and a counterweight is fixed to the output end of each of the plurality of electric actuators.

[0008] Preferably, the electric actuator one, the mounting base, the electric actuator two, and the counterweight are all arranged in a circumferential array about the substrate.

[0009] Preferably, the inner surface of the substrate has two limiting grooves 1, the top surface of the bottom plate has two limiting grooves 2, the toothed plate has two sets, the top of the two sets of toothed plates is fixed with limiting plates, the limiting plates are provided in two sets corresponding to the toothed plates, and the two sets of limiting plates are slidably connected to the limiting grooves 1 and 2 respectively.

[0010] Preferably, a motor is fixed to the top surface of the substrate, and a rotating shaft is fixed to the output end of the motor. Two gears are fixedly sleeved on the outer ring of the rotating shaft, and the two gears mesh with two sets of gear plates respectively.

[0011] Preferably, the elastic clamping member includes a cavity formed in the mounting box, an outer rod fixed to the inner wall of the cavity, a sliding groove formed in the outer rod, a spring slidably connected in the sliding groove, and a clamping rod fixed to the end of the spring.

[0012] Preferably, the outer rod, spring, and clamping rod are arranged in a linear array.

[0013] This utility model has the following beneficial effects:

[0014] This device can effectively adapt to the hoisting needs of various irregular building components, breaking the limitations of traditional rigid clamping structures, greatly improving the clamping stability and operational flexibility of irregular surface structures, avoiding damage to the surface of components caused by rigid clamping, and improving the drawbacks of a single force point by optimizing the clamping method, thus ensuring the integrity and stability of the building structure during hoisting.

[0015] This device can specifically solve the problems of unstable hoisting and easy tilting caused by the single stress point and uneven distribution of the center of gravity of irregular building components. It corrects the hoisting posture through a multi-dimensional adjustment mechanism. First, it offsets part of the eccentricity by adjusting the position of the counterweight, and then completes precise leveling through height fine adjustment. This reduces the risk of falling off due to tilting and shaking during hoisting, and greatly improves the safety and overall stability of hoisting operations.

[0016] This device ensures the accuracy and reliability of clamping and adjustment actions, effectively avoids displacement and misalignment of components during operation, further optimizes the stability of the entire hoisting process, improves the poor flexibility of traditional hoisting equipment, makes the hoisting and transfer of irregular building components smoother, and improves the overall hoisting operation efficiency.

[0017] The device has a wide range of applications and can flexibly handle irregular building components with different contours and center of gravity distributions. It eliminates the need to design special hoisting tools for specific structures, solving the problems of narrow applicability and high investment in special tools of traditional devices. It effectively reduces the pre-hoisting preparation costs and equipment investment costs, and improves the versatility and practicality of the equipment. Attached Figure Description

[0026] 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.

[0027] Example: This example aims to address the problems encountered during the hoisting of irregularly shaped building structures, such as unstable clamping, structural damage, and easy tilting / deviation due to irregular surface contours and uneven center of gravity distribution. It also highlights the poor adaptability and insufficient leveling / correction capabilities of traditional hoisting devices. Please refer to [link / reference needed]. Figure 1 - Figure 7A hoisting device for irregular building structures includes a base plate 1, on which a hoisting assembly 2 is mounted. The hoisting assembly 2 includes multiple electric push rods 21 fixed to the top surface of the base plate 1. A mounting base 22 is fixed to the top surface of the multiple electric push rods 21. A mounting hole 23 is opened on the mounting base 22. A rope 24 is installed in the mounting hole 23. A lifting ring 25 is installed on the rope 24. Multiple L-shaped plates 3 are fixed to the bottom surface of the base plate 1. A base plate 4 is fixed to the bottom surface of the multiple L-shaped plates 3. A clamping assembly 5 is installed between the base plate 1 and the base plate 4. The clamping assembly 5 includes a toothed plate 52 slidably connected to the top surface of the base plate 4. A connecting rod 53 is fixed to the end side of the toothed plate 52. A mounting box 57 is fixed to the side wall of the connecting rod 53. An elastic clamping member 6 is installed in the mounting box 57.

[0028] like Figure 3 As shown, multiple electric actuators 26 are fixed on the top surface of the substrate 1, and counterweights 27 are fixed at the output ends of the multiple electric actuators 26. The electric actuators 21, mounting base 22, electric actuators 26 and counterweights 27 are arranged in a circular array about the substrate 1.

[0029] Two limiting grooves 101 are formed on the inner surface of the substrate 1, and two limiting grooves 401 are formed on the top surface of the base plate 4. Two sets of toothed plates 52 are provided, and limiting plates 51 are fixed to the top of each set of toothed plates 52. The limiting plates 51 are provided in two sets corresponding to the toothed plates 52. The two sets of limiting plates 51 are slidably connected to the first limiting groove 101 and the second limiting groove 401, respectively. A motor 55 is fixed to the top surface of the substrate 1, and a rotating shaft 56 is fixed to the output end of the motor 55. Two gears 54 are fixedly sleeved on the outer ring of the rotating shaft 56, and the two gears 54 mesh with the two sets of toothed plates 52, respectively. It should be noted that the motor 55 has forward and reverse drive functions. When starting in the forward direction, it drives the clamping mechanism to perform clamping action, and when starting in the reverse direction, it provides power for the gears 54 to reset. The above-mentioned forward and reverse drive and reset methods are conventional drive settings in this field, so they will not be described in detail.

[0030] like Figures 5-7 As shown, the elastic clamping member 6 includes a cavity 61 opened in the mounting box 57. An outer rod 62 is fixed to the inner wall of the cavity 61. A sliding groove 63 is opened in the outer rod 62. A spring 64 is slidably connected in the sliding groove 63. A clamping rod 65 is fixed to the end side of the spring 64. The outer rod 62, the spring 64 and the clamping rod 65 are all arranged in a linear array.

[0031] In this embodiment: When using the device, firstly, precisely align and install the lifting ring 25 with the crane hook. During installation, each connection point between the rope 24 and the lifting ring 25 must be checked to ensure there is no looseness or wear at the connection. Simultaneously, ensure that the lifting ring 25 and the crane hook are fully engaged and securely locked to prevent safety issues such as detachment or slippage due to insecure connections during hoisting. The aforementioned method of aligning the lifting ring 25 with the crane is a well-known technique in the field of mechanical hoisting. After installation is completed and confirmed to be correct, start the crane to pull the entire hoisting device and slowly move it directly above the irregularly shaped building structure to be hoisted. During this process, control the crane's operating speed to prevent the device from colliding with the building structure or surrounding obstacles due to inertial swaying.

[0032] Then, precise alignment work begins. By raising and lowering the crane's hoisting ropes, the entire lifting device is lowered smoothly until the elastic clamping parts 6 on both sides of the device approach and lightly touch the corresponding sides of the irregular building structure to be lifted. Next, the clamping assembly 5 is activated. First, the motor 55 fixed on the top surface of the base plate 1 is turned on. After the motor 55 is powered on, it drives the output shaft 56 to rotate synchronously. When the shaft 56 rotates, it drives the two gears 54 fixedly sleeved on the outer ring to rotate together. Since the two gears 54 mesh with the two sets of toothed plates 52 respectively, the rotational force of the gears 54 is converted into the linear driving force of the toothed plates 52, causing the two sets of toothed plates 52 to move closer to each other on the top surface of the base plate 4.

[0033] Because the toothed plate 52 and the limiting plate 51 are fixedly connected, and the two sets of limiting plates 51 are respectively embedded in the limiting groove 101 of the base plate 1 and the limiting groove 401 of the bottom plate 4, during the sliding process of the toothed plate 52, the limiting plate 51 will slide smoothly along the corresponding limiting groove, which not only provides guidance for the toothed plate 52, but also restricts the sliding trajectory of the toothed plate 52 and prevents it from being deviated or misaligned. During this process, the toothed plate 52 drives the mounting box 57 and the elastic clamping member 6 inside to move synchronously through the connecting rod 53 until the two sets of elastic clamping members 6 completely fit against the surface of the irregular building structure from both sides, completing the initial positioning and clamping.

[0034] Considering the irregular and uneven surface contours of irregularly shaped building structures, traditional rigid clamping methods are prone to problems such as insecure clamping or damage to the structural surface. This device, however, achieves adaptive clamping through the elastic clamping element 6. When the clamping rod 65 in the elastic clamping element 6 contacts the surface of the building structure, it is subjected to the compressive force of the surface. The clamping rod 65 retracts inward along the groove 63 of the outer rod 62, compressing the internal spring 64. The compressed spring 64 generates a reverse elastic force, continuously pushing the clamping rod 65 to tightly conform to the surface of the irregularly shaped building structure. Simultaneously, the outer rod 62, spring 64, and clamping rod 65 are arranged in a linear array within the mounting box 57, enabling multi-point elastic clamping of the irregular structure from multiple points. This effectively avoids the impact damage to the building structure surface caused by rigid clamping, and flexibly adapts to irregularly shaped structures with different contours, significantly improving the stability and adaptability of the clamping, ensuring that the building structure does not slip laterally during hoisting.

[0035] After clamping, the crane is slowly lifted, raising the device and the clamped irregular building structure to a suitable height. Due to the uneven distribution of the center of gravity of the irregular building structure, eccentricity is prone to occur after lifting, causing the entire hoisting system to tilt. If the tilt angle is too large, it will compromise the clamping stability and even cause a major safety hazard of the building structure falling off. At this time, eccentricity compensation adjustment is required through the matching components of hoisting component 2. Electric actuator 26 is activated first, driving counterweight 27 to move radially along base plate 1. By changing the position of counterweight 27, the center of gravity distribution of the entire device is adjusted, thereby offsetting part of the tilting effect caused by eccentricity and achieving initial leveling.

[0036] However, the weight of the counterweight 27 has a rated upper limit. If there is still a slight tilt deviation after the counterweight adjustment and the hoisting stability requirement is not met, the electric actuator 21 at the corresponding position can be activated. The extension and retraction of the electric actuator 21 will drive the mounting base 22 and the rope 24 and lifting ring 25 above to make fine adjustments, thereby accurately adjusting the height of the corresponding position of the irregular building structure, realizing tilt correction, and ensuring that the entire hoisting system is in a horizontal and stable state.

[0037] It is worth noting that the electric actuator 21, mounting base 22, electric actuator 26, and counterweight 27 are all arranged in a circular array about the base plate 1. This layout allows for center of gravity adjustment and height fine-tuning from multiple directions and points. Combined with the sliding connection structure between the limiting plate 51 and the limiting grooves 101 and 401, it further ensures the stability and accuracy of the toothed plate 52 during sliding, ultimately achieving the horizontal lifting and transfer of irregularly shaped building structures. Throughout the process, the motor 55 driving the gear 54 and toothed plate 52, the extension and retraction of the electric actuators, and the elastic return of the spring 64 are all conventional power transmission and reset methods in the mechanical field, falling within the scope of known technology, and will not be elaborated upon here.

[0038] To better explain the above embodiments, this utility model proposes another implementation method: a hoisting method for an irregularly shaped building structure hoisting device, comprising the following steps:

[0039] Step 1: Device docking and installation. Precisely dock the lifting ring 25 of the device with the crane hook. Check each connection node between the rope 24 and the lifting ring 25 to ensure that there is no looseness or wear at the connection. Ensure that the lifting ring 25 and the crane hook are fully fitted and locked together to complete the stable connection between the lifting device and the crane.

[0040] Step 2: Position the device and start the crane to pull the hoisting device. Move it to the top of the irregular building structure to be hoisted. Control the crane's running speed to avoid the device from swaying due to inertia. Lower the hoisting device by raising and lowering the crane rope until the elastic clamp 6 approaches and lightly touches the corresponding side of the structure to be hoisted.

[0041] Step 3: Clamping of irregular structure. Start motor 55 drives shaft 56 to rotate gear 54. Through the meshing transmission between gear 54 and toothed plate 52, the two sets of toothed plates 52 move closer to each other along the top surface of base plate 4. The toothed plates 52 drive the mounting box 57 and elastic clamping parts 6 to move synchronously through connecting rod 53 until the two sets of elastic clamping parts 6 are in contact with the two sides of the irregular structure. The clamping rod 65 is squeezed by the structure surface and contracts along the slide groove 63 of the outer rod 62 to compress the spring 64. The spring 64 generates a reverse elastic force to push the clamping rod 65 to fit tightly against the surface of the irregular structure at multiple points, realizing adaptive elastic clamping.

[0042] Step 4: Adjust the center of gravity of the hoisting. Control the crane to slowly lift the device and the irregular structure to the specified height. If eccentricity or tilting occurs, first start the electric push rod 26 to drive the counterweight block 27 to move radially along the base plate 1. By adjusting the position of the counterweight, some of the eccentricity effect can be offset, and the initial leveling can be completed.

[0043] Step 5: Lifting posture correction. If there is still a tilting deviation after the counterweight adjustment, start the electric actuator 21 at the corresponding position. The extension and retraction of the electric actuator 21 will drive the mounting base 22, rope 24 and lifting ring 25 to make fine adjustments to the height, accurately correct the height of the corresponding position of the irregular structure, and ensure that the lifting system is in a horizontal and stable state.

[0044] Step Six: Lifting and Transfer. After confirming that the lifting posture is stable, control the crane to move along the preset path and transfer the irregular building structure to the target installation position. During the transfer, monitor the operation status of the device and the clamping status of the structure in real time to avoid displacement or damage to the structure due to shaking or collision.

[0045] Step 7: Structure in place. After reaching the target position, the irregular building structure is precisely aligned with the installation benchmark by the precise release and retraction of the crane rope and the auxiliary fine adjustment of the electric push rod. After the structure is stably placed and initially fixed, the control motor 55 is started in reverse, and the drive gear 54 is rotated in reverse to drive the toothed plate 52 and the elastic clamping part 6 to reset and release, thus releasing the clamping of the structure.

[0046] Step 8: Finish the hoisting operation. Control the crane to move the hoisting device away from the installed irregular structure and to a safe area. Check the operating status of each component of the device, clean any residual impurities on the surface of the clamping parts, and perform maintenance on key components such as rope 24, gear 54, and electric push rod to prepare for subsequent hoisting operations.

[0047] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations.

[0048] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
