Description

Technical Field

[0001] This invention relates to the field of tower crane technology, specifically to a multifunctional tower crane foundation conversion and installation mechanism and its installation and leveling method. Background Technology

[0002] Because tower cranes need to meet anti-overturning requirements for safe operation, their foundations are generally made of large-volume concrete with pre-embedded foundation sections that connect to the tower body for subsequent overall installation. However, in some long-term construction projects requiring conversion between different tower crane specifications, the traditional approach is to pre-embed foundation sections matching multiple specifications simultaneously to accommodate the installation of various tower crane sizes. Existing technology uses conversion sections to accommodate the installation of multiple tower crane sizes, such as a tower crane conversion section disclosed in Chinese Patent No. CN116750667A. This patent technology includes a mounting base, an outer casing, fixed legs, and an upper mounting plate. The mounting base connects to the anchor piles in the tower crane mounting base. The legs of the standard section at the bottom of the tower crane are vertically mounted on the upper mounting plate and connected to the fixed legs with bolts. The device is installed on an adjustment unit, which includes an upper mounting structure for mounting fixed legs. The upper mounting structure includes two parallel first slides and two second slides perpendicular to the first slides below them. Fixed legs are installed at the intersection of the first and second slides, and the fixed legs can slide on the first and second slides. The fixed legs can swing, thus better fitting with the standard section at the bottom of the tower crane. They can move freely along the horizontal plane, thus adapting to a wider range of tower crane sizes. However, the structure of this patent is relatively complex, and the stress distribution is poor. In addition, during a long construction period, the tower crane foundation may tilt due to uneven settlement of the underlying pad layer caused by the excessive weight of the large volume of concrete, or soil disturbance caused during basement construction. This patented technology cannot compensate for the levelness. Summary of the Invention

[0003] The technical problem to be solved by this invention is that the existing tower crane conversion mechanism is relatively complex, has poor force distribution, and cannot compensate for the level deviation of the tower crane foundation.

[0004] To solve the above-mentioned technical problems, the first part of the present invention adopts the following technical solution: a multifunctional tower crane foundation conversion and installation mechanism, including a first connecting seat for connecting with several standard sections of various specifications, a second connecting seat for connecting with corresponding foundation sections, and a connecting bracket for connecting the first connecting seat and the second connecting seat. The connecting bracket is provided with several radially arranged connecting arms. The top surface of each connecting arm is provided with several connecting seat mounting positions arranged sequentially along its extension direction. Several first connecting seats are provided and fixedly installed at the top of the end of their respective connecting arms. Several second connecting seats are provided and fixedly installed at the bottom of the end of their respective connecting arms. The middle part of the end of each connecting arm is provided with a leveling mechanism for adjusting the distance between the corresponding first connecting seats and the second connecting seats. After the distance between the corresponding first connecting seats and the second connecting seats is adjusted at the control end of the driving leveling mechanism, the several first connecting seats are kept in the same horizontal plane.

[0005] When in operation, this invention is applicable to the conversion and installation of tower cranes of various specifications, facilitating tower crane turnover configuration. It can configure tower cranes of appropriate specifications for different stages of construction requirements, reducing resource waste and saving construction costs. At the same time, the leveling mechanism can realize timely correction of level deviations, making it suitable for use in scenarios with long construction cycles and avoiding work stoppages or even accidents caused by tower crane foundation tilting due to external factors.

[0006] Preferably, the connecting bracket includes a first connecting plate, a second connecting plate, and a support plate. The first connecting plate has a plurality of radially arranged first arm plates, and the second connecting plate has second arm plates corresponding one-to-one with the plurality of first arm plates. The first and second connecting plates are arranged vertically at intervals, and the middle portions of the first and second connecting plates are connected as one unit by the support plate. The leveling mechanism includes a first leveling seat, a second leveling seat, a leveling wedge, and a leveling screw. The first leveling seat is fixedly installed on the bottom surface of the first arm plate, and the second leveling seat is fixedly installed on the top surface of the second arm plate. The bottom surface of the first leveling seat is recessed with a first leveling groove, and the second leveling... The top surface of the seat is recessed with a second leveling groove. The first and second leveling grooves cooperate with each other to form a funnel-shaped leveling space. The leveling wedge is slidably installed in the leveling space. The outer surface of the leveling wedge is provided with a leveling inclined surface that cooperates with the inner wall surface of the first and second leveling grooves. The leveling wedge is provided with a threaded hole extending along its length. The leveling screw is threadedly connected in the threaded hole. One end of the leveling screw extends outward to the outside of the connecting arm and is connected to the output end of the corresponding leveling drive device through a transmission assembly. The other end of the leveling screw extends inward and is rotatably limited between the first and second arm plates.

[0007] Preferably, the cross-sectional shape of the first leveling groove and the second leveling groove is set to V-shape, and the cross-sectional shape of the leveling wedge is set to a corresponding rectangle or rhombus.

[0008] When the present invention is working, the distance between the first connecting seat and the second connecting seat is adjusted by moving the leveling block in the leveling space. At the same time, the screw self-locking method is used to prevent the displacement of the leveling block during use, which is safe, reliable and has a strong load-bearing capacity. The control accuracy is improved by the cooperation between the leveling inclined surface and the first and second leveling grooves, the adjustment effect is high and the levelness consistency among the several first connecting seats after adjustment is good.

[0009] Preferably, the top surface of the middle part of the first connecting seat is provided with several lifting rings protruding upwards.

[0010] Preferably, a pressure sensor is also provided between the first connecting seat and the second connecting seat.

[0011] The second part of this invention adopts the following technical solution: an installation and leveling method for a multifunctional tower crane foundation conversion and installation mechanism, applied to the aforementioned multifunctional tower crane foundation conversion and installation mechanism, comprising the following steps:

[0012] S1: Measure the levelness of the tower crane foundation. Then, hoist the multi-functional tower crane foundation conversion installation mechanism to the top of the tower crane foundation and fix it to the tower crane foundation by connecting it to the foundation section embedded in the tower crane foundation through several second connecting seats.

[0013] S2: Install the first connecting seat of the corresponding specification in sequence according to the specifications of the tower crane standard section to be installed. Then, according to the measured level deviation, drive the leveling mechanism to adjust several first connecting seats to the same horizontal plane.

[0014] S3: Install the standard tower crane sections and the tower crane lifting and slewing mechanism in sequence, and enter the tower crane usage stage;

[0015] S4: Real-time monitoring of pressure changes between several sets of corresponding first and second connecting seats, and recording of pressure data;

[0016] S5: The pressure data recorded by the pressure distribution measurement system is processed to establish a pressure distribution model. The center of gravity offset data of the tower crane is obtained through the pressure distribution model, and a correction equation is established based on the center of gravity offset data. When the tower crane is working, the leveling mechanism is driven to adjust the spacing between several sets of first and second connecting seats according to the correction equation, the weight of the hoisted material and the displacement distance, thereby adjusting the center of gravity position of the tower crane, optimizing the force distribution of the tower crane and suppressing the overturning tendency of the tower crane.

[0017] Preferably, in step S5, when adjusting the spacing between several sets of first and second connecting seats according to the corrected equation, the weight of the hoisted material, and the displacement distance, thereby adjusting the center of gravity of the tower crane, optimizing the force distribution of the tower crane, and suppressing the overturning tendency of the tower crane, the following sub-steps are adopted:

[0018] A1: The center of gravity deviation value is obtained by calculating the weight and displacement distance of the suspended material using a modified equation;

[0019] A2: Before hoisting materials, the leveling mechanism is driven to adjust the spacing between several sets of first and second connecting seats according to the center of gravity deviation value, so that the pressure distribution model established by the adjusted pressure distribution data can compensate for the pressure distribution model of the tower crane during operation, thereby correcting the deviation.

[0020] When this invention is in operation, it can achieve leveling of several first connecting seats. By processing the pressure data through the pressure distribution measurement system, the center of gravity position of the tower crane is adjusted to optimize the force distribution of the tower crane, which can suppress the overturning tendency of the tower crane and prevent further tilting of the tower crane foundation. This greatly improves the safety factor of construction and avoids personal and property losses caused by tower crane overturning.

[0021] The beneficial technical effects of this invention include:

[0022] 1. This invention is applicable to the conversion and installation of tower cranes of various specifications, facilitating tower crane turnover configuration. It can configure tower cranes of appropriate specifications for different stages of construction requirements, reducing resource waste and saving construction costs. At the same time, the leveling mechanism can realize timely correction of level deviations, making it suitable for use in scenarios with long construction cycles and avoiding work stoppages or even accidents caused by tower crane foundation tilting due to external factors.

[0023] 2. This invention adjusts the distance between the first and second connecting seats by moving the leveling block within the leveling space. At the same time, it uses a screw self-locking method to prevent displacement of the leveling block during use, which is safe, reliable, and has a strong load-bearing capacity. The cooperation between the leveling inclined surface and the first and second leveling grooves improves the control accuracy, has a high adjustment effect, and the levelness consistency among the several first connecting seats after adjustment is good.

[0024] 3. This invention can achieve leveling of several first connecting seats. By processing the pressure data through the pressure distribution measurement system, the center of gravity position of the tower crane is adjusted to optimize the force distribution of the tower crane, which can suppress the overturning tendency of the tower crane and prevent further tilting of the tower crane foundation. This greatly improves the safety factor of construction and avoids personal and property losses caused by tower crane overturning.
