Description

Technical Field

[0001] The invention relates to the technical field of building construction, and in particular to a hoisting system for a heavy-weight pre-buried rigid steel column and a construction method thereof. Background Art

[0002] In the field of modern construction engineering, embedded rigid steel columns play a vital role as the core components of structural support. They not only lay a solid foundation on the ground, but also are closely connected to other steel bars through the connecting parts on both sides to build a solid foundation together. Especially for those large and heavy embedded rigid steel columns, their hoisting operation is undoubtedly the top priority in the entire construction process. Traditional hoisting methods, such as rotation and sliding methods, are powerless when facing super-heavy steel columns. This is mainly because the implementation of these methods is highly dependent on the lifting capacity of the lifting equipment. When the weight of the steel column exceeds the maximum load limit of a single lifting equipment, traditional hoisting methods are difficult to use.

[0003] In order to meet this challenge, the delivery method or double-machine lifting, which is a method of lifting by two lifting devices, is used. Although these methods solve the problem of overweight lifting to a certain extent, they put forward extremely high requirements on the coordination and technical proficiency of the operators. Double-machine lifting not only requires the precise cooperation of the two lifting devices, but also requires a high degree of synchronization during the operation, which undoubtedly increases the risk and complexity of construction. Therefore, it is urgent to develop a lifting system that can not only meet the needs of heavy lifting, but also simplify the operation process and reduce the difficulty of operation. Summary of the invention

After the transport vehicle 10 is lifted based on the mark of the reversing image, the rigid steel column body 50 is flipped over and just docked. This method simplifies the operation process and reduces the difficulty of operation for the driver.

The first load-bearing frame 24 is a retractable and movable load-bearing frame, and the preliminary calibration module 30 on its top can be controlled to move forward and backward through the third hydraulic cylinder, thereby finally controlling the movement of the rigid steel column body 50.

[0042] As a preferred embodiment, there are two flip modules 20, which are arranged side by side on the bottom wall of the placement groove 11. The two combinations can increase the stability of the device and ensure its operational stability when carrying heavy steel columns. The maximum flip angle of the flip module 20 is 90 degrees.

[0043] like Figure 4-5 As shown, the lifting assembly 32 includes a side connecting base plate 3201, which is fixedly arranged on the side of the second load-bearing frame 31, and two longitudinal main rods 3202 are arranged side by side on the top of the side connecting base plate 3201 close to the second load-bearing frame 31, and a lifting frame 3203 is slidably arranged between the two longitudinal main rods 3202, and a reinforcement plate is connected to the top of the two longitudinal main rods 3202, and a reinforcing plate is arranged on the side of the reinforcing plate away from the second load-bearing frame 31.

Combined with the front and rear movement effect of the first load-bearing frame 24 and the up and down movement effect of the lifting assembly 32, when the rigid steel column body 50 is placed on the third load-bearing plate, it is first ensured to be in the middle of the third load-bearing plate through the hydraulic clamping assembly 34, and based on the subsequent aiming module 35, its front and rear and up and down movements can be controlled to ensure that it is in the preset position.

[0046] like Figure 1 As shown, the aiming module 35 includes a distance detection unit and a lifting control unit 3502. The distance detection unit is arranged at the top of the third load-bearing plate near the tail side, and is used to detect the distance of the bottom plate of the steel column and the position of the mounting hole. The lifting control unit 3502 is used to control the coordinate position of the third load-bearing frame 33 and display the data detected by the distance monitoring unit 3501.

[0048] Embodiment 2

[0049] The embodiment of the present invention also discloses a method for hoisting and installing a heavy-weight pre-buried rigid steel column. Figure 7 , including the following steps:

[0050] S1. Preset calibration information and system initialization

[0051] The initial calibration information is accurately set in the proofreading control unit 43. This step requires that the electric telescopic rod 41 is in a fully extended state, and after the flip module 20 completes a 90-degree flip, its target area must accurately coincide with the detection range of the detection head 42. This setting provides a precise reference point for subsequent operations, ensuring the accuracy of the lifting operation.

[0052] S2. Lifting and initial clamping of rigid steel columns

[0053] Use lifting equipment to lift the rigid steel column body 50 steadily and place it accurately on the third load-bearing frame 33 of the transport vehicle 10. During this process, ensure that the docking portion 51 on the rigid steel column body 50 is in close contact with the front edge of the hydraulic clamping assembly 34. Then start the hydraulic clamping assembly 34 to firmly clamp the rigid steel column to prevent displacement in subsequent operations.

[0054] S3. Accurate detection and position calibration

[0055] Activate the aiming module 35 and use its high-precision sensor to detect the actual distance to the bottom of the rigid steel column body 50 and the precise position of the bottom docking hole. This information will be displayed in real time on the lifting control unit 3502 to provide intuitive visual feedback to the operator.

[0056] S4. Position fine-tuning and precise positioning

[0057] The operator accurately controls the first load-bearing frame 24 and the lifting assembly 32 through the operation buttons according to the display information on the lifting control unit 3502. This step involves fine adjustment of the rigid steel column in the front-to-back direction and the up-and-down direction to ensure that the initial position of the rigid steel column is completely consistent with the preset position, laying a solid foundation for subsequent docking work.

[0058] S5. Ground detection and virtual marking line generation

[0059] The detection head 42 is extended to its longest position, and the high-precision sensor mounted thereon is used to conduct a detailed detection of the ground directly below. The detection data will be processed in real time to form a virtual marking line, providing the operator with the precise position information of the ground bolt foundation. At the same time, through the display interface of the reversing radar, the operator can intuitively see the position of the ground bolt foundation, providing strong support for subsequent reversing alignment operations.

[0060] S6, hydraulic support unit 12 deployment and stable support

[0061] Once the exact position of the ground bolt foundation is found, the hydraulic support unit 12 is immediately deployed to form a stable support structure. This step is crucial to ensure stability and safety during the lifting operation.

[0062] S7, flip module 20 starts and rigid steel column rotates

[0063] The flip module 20 is started, and the coordinated action of the first hydraulic rod 22 and the second hydraulic rod 23 is precisely controlled to make the rigid steel column body 50 rotate smoothly by 90 degrees until it is perpendicular to the ground.

[0064] S8. Lowering and docking of rigid steel columns

[0065] Finally, by controlling the precise movement of the first hydraulic rod 22 and the second hydraulic rod 23 on the first load-bearing frame 24, the rigid steel column body 50 is slowly lowered until it is precisely docked with the ground bolt foundation. During the docking process, the position and state of the docking part 51 need to be continuously monitored to ensure the accuracy and firmness of the docking.
