Description

Technical Field

[0001] This invention relates to the field of vertical rotation and lifting construction technology, and in particular to an adaptive vertical rotation and lifting system and its construction process and control method. Background Technology

[0002] In the construction of spatial steel structures, current main methods include high-altitude in-situ installation, sliding, and lifting. The lifting method involves installing lifting equipment on structural columns or lifting frames to raise the pre-assembled spatial steel structure to its designed position. However, the lifting devices used in this method can only achieve single vertical lifting and cannot achieve angled lifting. Therefore, this invention patent proposes an adaptive, self-balancing lifting system for vertical rotation construction to meet the technological requirements of vertical rotation construction of large-span steel structures.

[0003] In addition, the lifting mechanism required for vertical rotation and lifting of large-span and long-length structures is also stronger, and traditional vertical lifting and single vertical rotation construction methods are difficult to meet the needs of such construction. Summary of the Invention

[0004] To address the above problems, this invention provides an adaptive vertical rotation and lifting system, its construction process, and control method. This invention is implemented as follows:

[0005] An adaptive vertical rotation and lifting system, applied to the vertical rotation and lifting construction process in building structures, lifts the structure to be lifted from the ground to mid-air via vertical rotation and lifting, including:

[0006] A pair of vertical rotating lifting beams are arranged in parallel and spaced apart. Each vertical rotating lifting beam is fixedly mounted on two lifting platforms of the same height on the vertical rotating lifting frame. Several opposing hydraulic cylinders are provided on the surface of the two vertical rotating lifting beams facing each other. Several lifting hydraulic cylinders are hinged to the lower surface of the two vertical rotating lifting beams. Opposing steel strands are pulled between the opposing hydraulic cylinders.

[0007] A plurality of bottom anchor brackets are respectively hinged to the surface of the vertical rotating structure to be lifted facing the lifting cylinder. Lifting steel strands are pulled between the bottom anchor brackets and the opposite lifting cylinders. When the vertical rotating structure to be lifted is in the initial state, the lifting steel strands form an angle of 30 to 50° with the horizontal plane, and the two sets of lifting steel strands on the two vertical rotating lifting beams are inclined in a direction that is separated from top to bottom.

[0008] The control module includes a control module, an alarm module, a tension sensor installed in the lifting cylinder, an angle sensor installed on the vertical lifting beam for monitoring the angle of the lifting cylinder, and a tension sensor installed in the counter-tension cylinder. The control module is communicatively connected to the lifting cylinder, the tension sensor, the angle sensor, the tension sensor, and the alarm module. The control module sends corresponding control signals to the alarm module or the lifting cylinder based on the monitoring information collected by the tension sensor, the angle sensor, and the tension sensor.

[0009] As a further improvement, the counter-pull cylinder is hinged to one side surface of the two vertical rotating lifting beams via a counter-pull bracket, and the lifting cylinder is hinged to the lower end surface of the two vertical rotating lifting beams via a lifting bracket.

[0010] The lifting support includes a support body. One end of the support body away from the vertical rotating lifting beam extends perpendicularly to the side away from / closer to the tie steel strand to form a mounting platform. The lifting cylinder is mounted on the mounting platform, and a protective cage covering the outer periphery of the lifting cylinder is also provided on the mounting platform.

[0011] As a further improvement, the bottom anchor bracket includes several hinge seats disposed on the side surface of the vertical rotating structure to be lifted facing the lifting cylinder. The bottom anchor body is hinged to the hinge seat by a locking pin. The end of the bottom anchor body near the vertical rotating lifting beam extends perpendicularly to the bracket body to form a fixed seat on the side away from / near the tie steel strand. The lifting steel strand extends into the fixed seat and is fixed in the fixed seat.

[0012] As a further improvement, the pull-out cylinder and the lifting cylinder are through-hole hydraulic jacks.

[0013] As a further improvement, several reinforcing ribs are provided between the two opposing and separating side surfaces of the two vertical rotating lifting beams and the lifting platform.

[0014] This invention also provides a construction process for an adaptive vertical rotation and lifting system, applicable to any of the adaptive vertical rotation and lifting systems described above, comprising the following steps:

[0015] S1. Complete the installation of the lifting frame and lifting platform;

[0016] S2. Assemble the vertical rotating lifting beam on the ground, install the lifting cylinder on the lower end surface of the vertical rotating lifting beam, and install the counter-pull cylinder on the opposite side surface of the two vertical rotating lifting beams.

[0017] S3. The assembled vertical rotating lifting beam is lifted onto the lifting platform, and the vertical rotating lifting beam is welded and fixed, and the tie steel strands are threaded through it;

[0018] S4. Fix a bottom anchor bracket on the vertical rotating structure to be lifted, and thread the lifting steel strand through it;

[0019] S5. System debugging;

[0020] S6. The lifting cylinder pulls the lifting steel strand, causing the vertical rotating structure to be lifted to rotate vertically and be lifted to the installation height.

[0021] As a further improvement, S5 also includes the following steps:

[0022] S501, The angle sensor acquires the angle between the current traction direction of each lifting cylinder and the horizontal plane and records it as angle information;

[0023] S502. Drive the lifting cylinder to tension the lifting steel strand, and the control module compares whether the current included angle information of each lifting cylinder is consistent. If they are inconsistent, manual adjustment is performed.

[0024] S503. Drive the lifting cylinder to pull the lifting steel strand so that the lifting cylinder rotates by 0.5 to 1.5°, and the control module compares whether the included angle information of each lifting cylinder is consistent after lifting. If they are inconsistent, manual adjustment is performed.

[0025] The present invention also provides a control method for an adaptive vertical rotation lifting system, applied to any of the adaptive vertical rotation lifting systems described above, comprising the following steps:

[0026] A1. The angle sensor acquires the angle between the current traction direction of each lifting cylinder and the horizontal plane and records it as angle information; the tension sensor acquires the current tension information of each lifting cylinder; and the tension sensor acquires the tension information of the opposing cylinders and sends it to the control module.

[0027] A2. The control module sends a corresponding lifting signal or stop signal to the lifting cylinder according to the included angle information;

[0028] A3. The control module sends a corresponding alarm signal to the alarm module based on the traction force information or the tension force information;

[0029] Specifically, when the included angle is no greater than 90°, the control module sends a lifting signal to the lifting cylinder. When the included angle is greater than or equal to 90°, the control module sends a stop signal to the lifting cylinder. The control module has preset tension force thresholds and tension force thresholds. When the tension force or tension force exceeds the preset tension force threshold or tension force threshold, the control module sends an alarm signal to the alarm module and simultaneously sends a descent signal to the lifting cylinder. The lifting cylinder releases the lifting steel strand until the vertical rotating structure to be lifted falls back to the ground, and the faulty components are then manually inspected.

[0030] The beneficial effects of this invention are as follows:

[0031] The vertical rotating structure rotates around a hinge. Therefore, the trajectory of the steel strand anchor end during vertical rotation and lifting is an arc. To prevent the steel strand from bending and breaking, the connection points of the lifting device, tie rod device, and bottom anchor support are designed as pin connections. This allows for adaptive adjustment of the connection points, ensuring that the force direction of the steel strand and the connection points at both ends is always consistent. Simultaneously, two parallel and spaced vertical lifting beams are used, allowing for simultaneous vertical rotation and lifting of the structures on both sides. This divides the long-span beam-column structure into two segments, reducing the overall strength required for a single vertical rotation structure.

[0032] Furthermore, by setting up counter-pull cylinders and counter-pull steel strands, the horizontal component force generated during the vertical rotation and lifting process can be borne. When the vertical rotation and lifting construction is carried out simultaneously on both sides, the horizontal component force can be mutually pulled. Compared with the traditional single-support vertical rotation and lifting construction, it can bear a larger weight of the structure to be lifted and is also safer. Attached Figure Description
