Description

Technical Field

[0001] This invention relates to the field of giant acrylic panel installation, and more particularly to a method for hoisting and constructing a giant acrylic panel for a deep-sea diving pool. Background Technology

[0002] Acrylic materials, due to their excellent optical transparency, pressure resistance and molding ability, have been widely used in special scenarios such as large underwater structures, marine engineering display windows and deep-sea diving pools. In deep-sea diving pool projects, acrylic sheets not only undertake key functions such as water isolation, pressure bearing and transparency, but also directly affect the safety and service life of the pool structure.

[0003] As the scale of the project expands, the requirements for the size and strength of acrylic sheets in deep-sea pools are increasing. Traditional small and medium-sized acrylic sheets can no longer meet the structural requirements. Therefore, giant acrylic sheets with huge size, thickness and weight have begun to be used in the project. In a certain deep-sea pool project, a single acrylic sheet A is 13.4 meters high and weighs more than 21.5 tons, while sheet B weighs 24 tons. They are typical giant acrylic structural components.

[0004] However, current conventional hoisting methods are mainly based on the development of small and medium-sized panels, and a systematic process has not yet been formed to meet the complex needs of hoisting giant panels. Most existing hoisting technologies are based on "direct hoisting and positioning", which cannot meet the needs of precise operation of giant acrylic panels in the special structure and extreme working conditions of deep-sea diving pools. This results in problems such as low efficiency, poor safety, and uncontrollable construction. Summary of the Invention

[0005] The purpose of this invention is to provide a method for hoisting giant acrylic panels in confined structural spaces, addressing the challenge of hoisting ultra-large and ultra-heavy acrylic sheets. This method integrates multi-point flexible binding, track sliding, attitude control, and buffer protection, significantly improving the safety, stability, and precision of hoisting operations. It is suitable for the challenging installation of giant transparent components in special scenarios such as deep-sea diving pools and large underwater windows, and has good engineering adaptability.

[0006] This invention is achieved through the following measures:

[0007] A method for hoisting and installing a giant acrylic panel in a deep-sea diving pool, characterized by comprising:

[0008] S1. Transportation preparation: The acrylic sheets are divided into sections and transported to the deep-sea pool construction site by transport vehicles, and then placed on multiple tank vehicles and moved along the transport route to the hoisting platform position.

[0009] S2. Lifting Platform Construction: A steel structure lifting platform is erected around the central mega-column. Track beams and trolleys are erected around the central mega-column on the lifting platform, and three electric hoists are installed on the trolleys.

[0010] S3. Lifting slings: Use standard lifting nylon slings to tie the acrylic sheet. The bottom of the bottom sling is padded with rubber pads. At the same time, use the horizontal wraparound slings set above and below for positioning. Lifting slings are set at the front and back. The rear lifting sling is connected to the corresponding electric hoist through the first manual hoist. At the same time, a pair of second manual hoists connected to the upper horizontal wraparound slings are set on the ground.

[0011] S4. Lifting process control: The electric hoist slowly raises the hook, the tank pushes synchronously, and the first and second manual hoists control the attitude in real time.

[0012] S5. Advancement and Installation Positioning: After the acrylic sheet is lifted, it is moved to the predetermined position along the circumference via the track beam, and then placed on the base equipped with a lifting air cushion. The inner and outer supports are then used for positioning and fixing.

[0013] S6. Sling Removal: After confirming that the acrylic plate is fixed, gradually loosen the hooks and remove the bottom sling and horizontal sling;

[0014] S7. Lifting and positioning: Place a 100mm high acrylic pad on the base under the acrylic sheet. After removing the bottom lifting pad of the acrylic sheet step by step, the acrylic sheet will fall onto the acrylic pad.

[0015] The invention also has the following specific features:

[0016] The nylon strap is a 300mm wide orange standard lifting strap.

[0017] The acrylic sheet is secured using standard lifting nylon straps, including three lifting straps at the front and back, three bottom straps, and two horizontal wrapping straps at the top and bottom. The bottom straps are padded with rubber.

[0018] The three lifting slings at the front and rear are respectively connected to three electric hoists.

[0019] The inner and outer supports include a standardized tripod on the inner side and several adjusting screws on the outer steel frame.

[0020] The second hand chain hoist is fixed to the expansion bolt at the top of the structural concrete column.

[0021] The beneficial effects of this invention are as follows: This invention addresses the challenge of hoisting ultra-large and ultra-heavy acrylic sheets in confined structural spaces by constructing an integrated process flow that includes multi-point flexible binding, track sliding, attitude control, and buffer protection. This significantly improves the safety, stability, and precision of hoisting operations and is suitable for the challenging installation requirements of giant transparent components in special scenarios such as deep-sea diving pools and large underwater windows, demonstrating good engineering adaptability.

[0034] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0035] See Figure 1-11 A method for hoisting and installing a giant acrylic panel in a deep-sea diving pool, comprising:

[0036] S1. Transportation preparation: The acrylic sheets are divided into sections and transported to the deep-sea pool construction site by transport vehicles, and placed on multiple tank vehicles 9 and moved along the transport route to the position of the hoisting platform 2.

[0037] According to the construction drawings and installation sequence, the acrylic sheet 10 is reinforced on the way to the site. The acrylic sheet 10 is transported by transport truck through the construction gate and transported horizontally by multiple tank vehicles 9. Due to the extremely large mass of the giant sheet, the transportation route needs to be reinforced to ensure transportation safety and structural stability.

[0038] S2, Lifting Platform 2 Construction: A steel structure lifting platform 2 is erected around the central mega-column 1. A track beam 3 and a trolley are erected around the central mega-column 1 on the lifting platform 2. Three electric hoists 4 are installed on the trolley.

[0039] The construction of the central mega-column 1 (with internal concrete filling and internal cross ribs) has been completed, and the construction of its top umbrella-shaped main steel frame has been completed. The hoisting platform 2 is being built around the central mega-column 1.

[0040] The hoisting platform 2 is a steel structure system. The top of the platform is equipped with a track beam 3 and three 10t electric hoists 4, which are specially used for hoisting giant plates. The main steel column of the platform is reinforced by HW300 steel reaction support to ensure that the platform has sufficient load-bearing capacity and structural rigidity. In addition, the track beam 3 is fixed on the steel clamp structure on the central giant column 1 and can be arranged into a ring track in the circumferential direction to realize the precise rotation and sliding of the plate from the hoisting port to the periphery.

[0041] S3. Lifting straps: Use standard lifting nylon straps to tie the acrylic sheet 10. The bottom of the bottom sling 5 is padded with rubber pads. At the same time, it is positioned in conjunction with the horizontal wraparound slings 6 set above and below. Lifting slings 7 are set at the front and back. The rear lifting sling 7 is connected to the corresponding electric hoist 4 through the first manual hoist 8. At the same time, a pair of second manual hoists 12 connected to the upper horizontal wraparound sling 6 are set on the ground.

[0042] S4. Lifting process control: Electric hoist 4 slowly raises the hook, tank 9 pushes synchronously, first hand hoist 8 and second hand hoist 12 control the posture in real time to realize the slow lifting, erection, rotation and gear shifting of acrylic plate 10;

[0043] In the initial stage of hoisting, the acrylic sheet 10 is placed horizontally on the tank vehicle 9. The electric hoist 4 is slowly raised by synchronous control, while the tank vehicle 9 slowly follows the acrylic sheet 10 to gradually lift the sheet from a horizontal to a vertical position.

[0044] During the lifting process, the first hand chain hoist 8 and the second hand chain hoist 12 installed on both sides of the plate body serve as attitude control tools to control the lifting attitude and angle in real time, preventing the plate body from swaying left and right or tilting backward. At the same time, the tank 9 slowly follows the acrylic plate 10.

[0045] S5. Advancement and Installation Positioning: After the acrylic sheet 10 is lifted, it moves along the circumferential direction to the predetermined position via the track beam 3 and is lowered onto the base 11 equipped with a lifting air cushion. Then, it is positioned and fixed using inner and outer supports.

[0046] After the plate is successfully erected, the acrylic plate 10 is rotated and slid in the horizontal plane with the help of the trolley on the track beam 3. After reaching the target installation opening, the electric hoist 4 slowly lowers the hook, and the acrylic plate 10 falls into the bottom lifting air cushion. After the plate is initially in place, the inner and outer brackets are immediately installed for positioning and fixation.

[0047] The inner tripod 14 provides rigid support for the lateral stability of the acrylic sheet 10. The outer adjusting screw 13 is set on the steel structure beam through actual measurement. Its tail is pressed against the acrylic sheet 10 for slow pushing and fitting adjustment. All contact points are padded to prevent damage to the sheet.

[0048] S6. Sling Removal: After confirming that the acrylic plate 10 is fixed, gradually loosen the hooks and remove the bottom sling 5 and the horizontal sling;

[0049] S7. Lifting and positioning: Place a 100mm high acrylic pad on the base 11 below the acrylic sheet 10. After removing the bottom lifting pad of the acrylic sheet step by step, the acrylic sheet will fall onto the acrylic pad.

[0050] The nylon straps are 300mm wide and are standard orange type lifting straps.

[0051] The acrylic sheet 10 is secured using standard lifting nylon straps, including three lifting straps 7 at the front and rear, three bottom-supporting straps 5, and two horizontal wrapping straps 6 at the top and bottom. The bottom-supporting straps 5 have rubber pads at the bottom.

[0052] The three lifting slings 7 are connected to three electric hoists 4 respectively.

[0053] The inner and outer supports include the inner standardized tripod 14 and several adjusting screws 13 on the outer steel frame.

[0054] The second hand chain hoist 12 is fixed to the expansion bolt at the top of the structural concrete column.

[0055] To ensure the structural safety and stress balance of the giant acrylic panel 10 during the hoisting process, flexible slings were used for comprehensive protection and support.

[0056] The slings are made of 300mm wide standard orange nylon slings, which have high tensile strength and good flexibility. They are suitable for use on 10 types of vulnerable components of acrylic sheets. Rubber pads are provided at the bottom of all slings that come into contact with the sheet to prevent scratches from hard objects, increase friction and provide cushioning protection.

[0057] The specific binding method is as follows:

[0058] Lifting sling material and specifications: All 300mm wide standard orange nylon lifting slings are used. The lifting slings are flexible, have high load-bearing capacity, and do not cause hard damage to the surface of the acrylic sheet.

[0059] Rubber pads are added to the bottom of the slings where they contact the plate to prevent scratches or indentations caused by sharp corners or edges, while also increasing friction and improving lifting stability.

[0060] Sling arrangement: The overall arrangement adopts a multi-layered, multi-point support method of "six lifting points + three bottom supports + two horizontal supports", as detailed below:

[0061] Lifting slings (6 in total, 3 in the front and 3 in the back);

[0062] Set on the upper part of the acrylic plate 10, evenly distributed, with three in each group, each driven independently by three 10t electric hoists 4 to ensure synchronous lifting. This sling is the main load-bearing structure of the entire hoisting process, controlling vertical lifting.

[0063] Bottom suspenders (quantity x 3);

[0064] Located at the bottom of the board, it directly supports the entire board. Rubber pads are placed between the slings and the board to prevent wear on sharp corners, thus playing a dual role of load-bearing support and shape stability.

[0065] Six horizontal wrap-around slings (one set for the top and one for the bottom);

[0066] Located at the lower part (5200mm from the bottom) and upper part (8200mm from the bottom) of the plate, the horizontal straps are arranged in a ring. Their main functions are to limit the horizontal movement and position the bottom sling 5, preventing the plate from swinging, shifting, or the straps from sliding during lifting. The horizontal straps do not bear vertical loads, but they are crucial to the overall stability.

[0067] This binding structure fully considers the high quality and high risk characteristics of the giant acrylic sheet 10, and achieves the comprehensive goals of "multi-point hoisting, flexible protection, synchronous control, and safe advancement". Its core advantages are that it greatly reduces the risk of damage to the sheet, improves the controllability of hoisting, and provides a good foundation for subsequent attitude control and precise installation.

[0068] The technical features of this invention not described can be implemented by or using existing technology, and will not be repeated here. Of course, the above description is not a limitation of this invention, and this invention is not limited to the examples above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of this invention should also be within the protection scope of this invention.
