Description

Technical Field

[0001] This utility model relates to the field of building wall hoisting and leveling technology, specifically to a building wall hoisting and leveling device. Background Technology

[0002] In the construction industry, the hoisting and installation of precast walls is one of the core processes, and its installation accuracy and work efficiency directly affect the stability of the overall building structure and the construction progress. With the advancement of building industrialization, precast walls are widely used due to their advantages such as convenient construction and controllable quality, and the corresponding hoisting and leveling equipment has become a key piece of equipment to ensure construction quality.

[0003] In existing technologies, the hoisting and leveling of building walls largely relies on cranes in conjunction with manual adjustments. The leveling accuracy is greatly affected by the skill level of the operators, requiring visual judgment of wall offsets and height differences, which is prone to errors. Such equipment is ill-suited to effectively handle the effects of external factors such as wind interference and improper support of the crane outriggers. During hoisting, walls are prone to lateral, longitudinal, and torsional deviations. Large-scale adjustments using only a crane are not only insufficiently accurate but may also amplify the offset due to improper operation, leading to repeated calibrations and adjustments, thus reducing work efficiency.

[0004] Therefore, we propose a building wall hoisting and leveling device to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this utility model is to provide a building wall hoisting and leveling device to solve the problems mentioned in the background art, such as insufficient accuracy of existing equipment adjustment, and the possibility of amplifying the offset due to improper operation, resulting in repeated calibration and adjustment and reduced work efficiency.

[0006] This utility model provides the following technical solution: a building wall hoisting and leveling device, including a support plate, a sling fixedly connected to the support plate, a leveling component provided on the bottom surface of the support plate, the leveling component including a concave seat one fixedly connected to the bottom surface of the support plate, a convex seat slidably connected inside the concave seat one, a concave seat two fixedly connected inside the convex seat, a slider slidably connected inside the concave seat two, a protective box fixedly connected to the bottom surface of the slider, a drive shaft rotatably connected to the bottom surface of the protective box, a support plate fixedly connected to the bottom of the drive shaft, an electric push rod fixedly connected to the bottom surface of the support plate, a lifting device fixedly connected to the output end of the electric push rod, and a scanning probe installed on the bottom surface of the lifting device.

[0007] Preferably, a motor is fixedly connected to the side wall of the concave seat, a lead screw is fixedly connected to the output end of the motor, and the convex seat is threadedly installed with the lead screw.

[0008] Preferably, a motor is fixedly connected to the side wall of the concave seat, a lead screw is fixedly connected to the output end of the motor, and the slider is threadedly installed with the lead screw.

[0009] Preferably, the protective box has a cavity, and a motor is fixedly connected inside the cavity. The output end of the motor is fixedly connected to the transmission shaft. Multiple support frames are fixedly connected to the outer wall of the transmission shaft, and the support frames are fixedly connected to the support plate.

[0010] Preferably, two sets of electric actuators are symmetrically arranged, and the output ends of both sets of electric actuators are fixedly connected to the top surface of the lifting device.

[0011] Preferably, the scanning probe is electrically connected to motor one, motor two, motor three and electric actuator respectively.

[0012] This utility model has the following beneficial effects:

[0013] This equipment effectively solves problems such as offset, torsion, and height difference during the hoisting, transportation, and positioning of building walls, significantly improving the accuracy of wall hoisting and leveling. Through a real-time detection and collaborative adjustment mechanism, it eliminates the need for operators' visual judgment and large-scale crane adjustments, effectively avoiding the problem of offset amplification caused by improper human operation, reducing reliance on operators' skill levels, decreasing the frequency of repeated adjustments and calibrations, and improving hoisting operation efficiency.

[0014] This equipment can specifically eliminate lateral, longitudinal, and torsional deviations, while precisely compensating for vertical height differences. It ensures that the wall installation position, angle, and levelness all meet preset requirements, guaranteeing wall installation quality and structural stability, and laying a solid foundation for subsequent construction procedures. It effectively resists the effects of external environmental and equipment factors such as wind interference and crane body tilt, making it suitable for complex outdoor operating scenarios and improving the adaptability and reliability of hoisting operations.

[0015] This equipment, through automated adjustment, avoids applying additional inertial or horizontal forces to the wall during manual adjustment, reducing the risk of damage to the wall due to improper stress and protecting the integrity of the wall to be installed. The overall operation process is more efficient and stable, balancing construction efficiency and installation accuracy, and reducing hoisting construction costs. Attached Figure Description

Detailed Implementation

[0022] 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.

[0023] Example: This example aims to address the problems encountered during the hoisting, transportation, and positioning of building walls. These problems arise from external environmental interference, limitations in crane operation, and human error, leading to wall misalignment, torsion, and height differences. Relying solely on crane adjustments results in insufficient precision and can easily amplify misalignment, ultimately causing low hoisting efficiency, poor installation accuracy, and difficulty in ensuring wall installation stability. Please refer to [link / reference]. Figure 1 - Figure 5 A building wall hoisting and leveling device includes a support plate 1, on which a sling 2 is fixedly connected. A leveling component 3 is provided on the bottom surface of the support plate 1. The leveling component 3 includes a concave seat 31 fixedly connected to the bottom surface of the support plate 1, a convex seat 34 slidably connected within the concave seat 31, a concave seat 35 fixedly connected within the convex seat 34, a slider 38 slidably connected within the concave seat 35, a protective box 39 fixedly connected to the bottom surface of the slider 38, a drive shaft 312 rotatably connected to the bottom surface of the protective box 39, a support plate 314 fixedly connected to the bottom of the drive shaft 312, an electric push rod 315 fixedly connected to the bottom surface of the support plate 314, a lifting device 4 fixedly connected to the output end of the electric push rod 315, and a scanning probe 5 installed on the bottom surface of the lifting device 4.

[0024] like Figure 3 - Figure 5As shown, a motor 32 is fixedly connected to the side wall of the concave seat 31, and a lead screw 33 is fixedly connected to the output end of the motor 32. The convex seat 34 is threadedly installed with the lead screw 33. A motor 36 is fixedly connected to the side wall of the concave seat 35, and a lead screw 37 is fixedly connected to the output end of the motor 36. The slider 38 is threadedly installed with the lead screw 37.

[0025] The protective box 39 has a cavity 310 inside, and a motor 311 is fixedly connected inside the cavity 310. The output end of the motor 311 is fixedly connected to the drive shaft 312. Multiple support frames 313 are fixedly connected to the outer wall of the drive shaft 312, and the support frames 313 are fixedly connected to the support plate 314.

[0026] Two sets of electric actuators 315 are symmetrically arranged, and the output ends of both sets of electric actuators 315 are fixedly connected to the top surface of the lifting device 4. The scanning probe 5 is electrically connected to motor 1 32, motor 2 36, motor 3 311 and electric actuators 315 respectively.

[0027] In this embodiment: When using the device, first connect the sling 2 on the support plate 1 to the crane. After confirming a secure connection, lower the crane to drive the entire lifting and leveling equipment to descend synchronously, causing the lifting device 4 below to gradually approach and contact the wall to be lifted. Subsequently, the drive structure of the lifting device 4 is activated, causing the clamping components to move relative to each other, stably clamping and fixing the wall to ensure that the wall does not fall off or loosen during the lifting process. Since the specific clamping drive method and clamping structure of the lifting device 4 are well-known technologies in the art, they will not be described in detail here.

[0028] Once the lifting device 4 has secured the wall, the crane can be started to lift and transport the wall to the preset installation location. During the lifting, transport, and positioning process, the wall is susceptible to positional shifts due to various external factors and operational influences. For example, if the crane's lifting or horizontal movement speed is too fast, the wall will shift in the opposite direction of movement due to inertia. The anti-sway mechanism of the conventional lifting device 4 has a limited response speed and cannot quickly counteract this inertial force, causing the wall to shift in the opposite direction to the crane's running direction, and the amount of shift will gradually increase as the running speed increases. Other factors, such as wind interference during outdoor operations, insufficient padding of the crane's outriggers or ground subsidence causing slight tilting of the crane body, and uneven force distribution when the lifting device 4 is connected to the preset lifting point on the wall, can all cause varying degrees of wall shift. If large-scale adjustments are made solely by cranes, not only is it difficult to guarantee the accuracy of the adjustments, but improper manual control by operators can also apply additional inertial or horizontal forces to the wall, further amplifying the original slight deviation. This can ultimately lead to the wall deviating significantly from the installation reference and becoming difficult to level, requiring repeated adjustments and calibrations, which greatly reduces the efficiency of hoisting operations and the accuracy of wall installation.

[0029] like Figure 3 - Figure 5 As shown, after the crane moves the lifting device 4 and the wall to the preset installation range, the crane's power output and position control stop, and the system enters its own precise micro-adjustment stage. During the adjustment operation, the scanning probe 5 installed on the bottom surface of the lifting device 4 is activated synchronously to detect the current spatial position, offset angle, and deviation data of the wall from the installation baseline and reference surface in real time. At the same time, the detected precise signals are synchronously transmitted to the control terminals of motor 1 32, motor 2 36, motor 3 311, and each electric actuator 315, realizing the coordinated linkage of each drive component and ensuring the precise synchronization of the adjustment action.

[0030] Based on the lateral offset data fed back by the scanning probe 5, motor 32 is started first. After motor 32 starts working, it drives the lead screw 33 at the output end to rotate synchronously. Since the convex seat 34 and the lead screw 33 are connected by a threaded engagement, and the convex seat 34 is limited and slidably connected inside the concave seat 31, the rotational motion of the lead screw 33 can be converted into the linear motion of the convex seat 34, driving the convex seat 34 to slide smoothly horizontally along the length direction of the concave seat 31. This, in turn, drives the concave seat 35, slider 38, protective box 39, support plate 314, lifting device 4 and the wall below the convex seat 34 to adjust their lateral positions together, gradually eliminating the lateral offset of the wall and making the lateral position of the wall fit the installation reference.

[0031] After the lateral offset correction is completed, motor 36 is started to calibrate the longitudinal position. Motor 36 drives lead screw 37 to rotate. Slider 38 is threadedly connected to lead screw 37 and slides within concave seat 35. Driven by lead screw 37, slider 38 slides horizontally along the length of concave seat 35. This sliding direction is perpendicular to the lateral sliding direction of convex seat 34, thereby achieving precise fine-tuning of the longitudinal position of the wall, ensuring that the wall is completely aligned with the installation reference on the horizontal plane, and eliminating horizontal positional deviation.

[0032] After the horizontal position is adjusted to the correct position, motor 311 is started to correct the angle and eliminate the torsional offset of the wall. Motor 311 is fixedly installed in the cavity 310 of the protective box 39, and its output end is rigidly connected to the drive shaft 312. After motor 311 is started, it drives the drive shaft 312 to rotate synchronously. The bottom of the drive shaft 312 is firmly connected to the support plate 314 through multiple support brackets 313, which can synchronously drive the support plate 314 and the hanging device 4 below and the wall to rotate together, thereby adjusting the horizontal installation angle of the wall so that the placement angle of the wall fully meets the preset installation requirements and avoids the impact of torsional offset on the subsequent installation quality.

[0033] After the angle and horizontal position are adjusted, the corresponding electric actuators 315 are activated to perform vertical leveling based on the vertical deviation data fed back by the scanning probe 5. The electric actuators 315 are evenly fixed on the bottom surface of the support plate 314, and their output ends are firmly connected to the hanger 4. By precisely controlling the extension and retraction of each electric actuator 315, the height of different positions of the hanger 4 is adjusted, thereby compensating for the vertical height difference of the wall and achieving the final precise leveling operation of the wall.

[0034] The entire adjustment process relies on real-time feedback data from the scanning probe 5 for dynamic calibration. All drive components work together and move in precise coordination, eliminating the need for operators to make visual judgments or for large-scale adjustments by the crane. This effectively avoids the problem of offset amplification caused by improper human operation, improves the accuracy and efficiency of wall hoisting and leveling, and ensures the structural stability and construction quality of the wall after installation.
