Description

Technical Field

[0001] The present invention relates to the field of installation of giant acrylic plates, and particularly to a hoisting construction method for huge acrylic plates in a deep diving pool. Background Art

[0002] Due to its excellent optical transparency, pressure resistance and forming ability, acrylic materials have been widely used in special scenarios such as large underwater structures, ocean engineering display windows and deep diving pools. Among them, in deep diving pool projects, acrylic plates not only undertake key functions such as water isolation, pressure bearing and perspective, but also directly affect the structural safety and service life of the pool body.

[0003] With the expansion of the project volume, the requirements for the size and strength of acrylic plates in deep diving pools are increasing day by day. Traditional medium and small-sized acrylic plates can no longer meet the structural requirements. Therefore, giant acrylic plates with a single large size, large thickness and heavy weight are beginning to be used in projects. In a certain deep diving pool project, the height of a single acrylic A plate reaches 13.4 meters and the mass exceeds 21.5 tons, and the weight of B plate reaches 24 tons, which belongs to typical giant acrylic structural components; However, current conventional hoisting methods are mainly developed based on medium and small-sized plates, and a systematic process adapted to the complex hoisting requirements of giant plates has not been formed. Most of the existing hoisting technologies are mainly "direct hoisting - in-place", which cannot meet the refined operation requirements of giant acrylic plates in the special structure and extreme working conditions of deep diving pools, and there are problems such as low efficiency, poor safety and uncontrollable construction. Summary of the Invention

[0004] The purpose of the present invention is to provide a hoisting construction method for huge acrylic plates in a deep diving pool. The present invention constructs an integrated process flow such as multi-point flexible bundling, track sliding, attitude control, buffer protection, etc. for the hoisting problem of super-large volume and overweight acrylic plates in a limited structural space, significantly improving the safety, stability and accuracy of hoisting operations, and being applicable to the high-difficulty installation requirements of giant transparent components in special scenarios such as similar deep diving pools and large underwater windows, and having good engineering adaptability.

[0005] The present invention is achieved by the following measures: A hoisting construction method for huge acrylic plates in a deep diving pool, characterized by including: S1. Transportation preparation: Transport the acrylic plates in blocks to the construction site of the deep diving pool by transport vehicles, and place them on multiple tracked vehicles to move along the transport route to the hoisting platform position; S2. Hoisting platform construction: Build a steel structure hoisting platform around the central giant column. Install track beams and trolleys around the central giant column on the hoisting platform, and 3 electric hoists are arranged on the trolleys; S3. Sling Binding: Use standard lifting nylon straps to bind the acrylic board. Place rubber cushions at the bottom of the bottom sling, and at the same time, cooperate with the horizontally surrounding slings arranged up and down for positioning. At the same time, arrange lifting slings front and back. The rear lifting sling is connected to the corresponding electric hoist through a first manual hoist. At the same time, set a pair of second manual hoists on the ground that are connected to the upper horizontally surrounding sling. S4. Hoisting Process Control: The electric hoist slowly raises the hook, and the tank car synchronously pushes. The first manual hoist and the second manual hoist control the attitude in real time. S5. Gear Engagement and Installation Positioning: After the acrylic board is hoisted, the acrylic board moves along the circumferential direction to the predetermined position through the track beam, and is lowered to the base provided with a lifting air cushion. Then, use internal and external brackets for positioning and fixing. S6. Sling Removal: After confirming that the acrylic board is fixed, gradually release the hook and remove the bottom sling and the horizontal sling. S7. Hoisting in Place: Place 100-mm-high acrylic pads on the base under the acrylic board. After gradually removing the bottom lifting pads of the acrylic, the acrylic falls onto the acrylic pads.

[0006] The specific features of the present invention also include: The nylon strap is an orange standard lifting strap with a width of 300 mm.

[0007] Use standard lifting nylon straps to bind the acrylic board, including 3 front and rear lifting slings, 3 bottom slings, and 2 upper and lower horizontally surrounding slings. A rubber cushion is provided at the bottom of the bottom sling.

[0008] The 3 front and rear lifting slings are respectively connected to 3 electric hoists.

[0009] The internal and external brackets include an inner standardized tripod and several adjusting screws on the outer steel frame.

Specific implementation manners

[0024] To clearly illustrate the technical features of this solution, the following elaborates on this solution through specific implementation manners.

[0025] See Figures 1-11 , a construction method for hoisting a huge acrylic board in a deep diving pool, including: S1. Transportation preparation: Transport the acrylic board in blocks to the construction site of the deep diving pool by transport vehicles, and place them on multiple tank trucks 9 to move along the transport route to the position of the hoisting platform 2; According to the construction drawings and the installation sequence, the structural reinforcement treatment is carried out on the access path of the acrylic board 10. The acrylic board 10 enters the site through the construction gate by a transport truck and is horizontally transported by multiple tracked vehicles 9. Since the mass of the giant board is extremely large, the transport path needs to be strengthened to ensure transport safety and structural stability; S2. Erection of the hoisting platform 2: A steel structure hoisting platform 2 is erected around the central giant column 1. A track beam 3 and a pulley are erected around the central giant column 1 on the hoisting platform 2, and 3 electric hoists 4 are arranged on the pulley; The central giant column 1 (filled with concrete inside and with cross ribs added) has been constructed, and the umbrella-shaped main steel frame at its top has been constructed. The hoisting platform 2 is erected around the central giant column 1; The hoisting platform 2 is a steel structure system. A track beam 3 and 3 10t electric hoists 4 are arranged at its top, which are specially used for the hoisting operation of giant plates. The main steel columns of the platform are strengthened by the reaction support of HW300 steel sections to ensure that the platform has sufficient bearing capacity and structural rigidity. In addition, the track beam 3 is fixed on the steel hoop structure on the central giant column 1 and can be arranged in a circular track in the circumferential direction to realize the precise rotary sliding of the plate body from the hoisting port to the periphery; S3. Strapping with slings: The acrylic board 10 is strapped with standard hoisting nylon slings. A rubber soft pad is placed at the bottom of the bottom sling 5, and at the same time, horizontal circumferential slings 6 are arranged up and down for positioning. At the same time, lifting slings 7 are arranged front and back. The rear lifting sling 7 is connected to the corresponding electric hoist 4 through a first chain block 8, and a pair of second chain blocks 12 connected to the upper horizontal circumferential sling 6 are arranged on the ground; S4. Control during the hoisting process: The electric hoist 4 slowly raises the hook, and the tracked vehicle 9 pushes synchronously. The first chain block 8 and the second chain block 12 control the posture in real time to realize the slow hoisting, erection, rotation and gear engagement of the acrylic board 10; At the initial stage of hoisting, the acrylic board 10 is placed horizontally on the tracked vehicle 9. By synchronously controlling the electric hoist 4 to slowly raise the hook, and at the same time, the tracked vehicle 9 slowly follows the movement of the acrylic board 10, the plate body is gradually erected from the horizontal to the vertical posture; During the hoisting process, the first chain block 8 and the second chain blocks 12 installed on both sides of the plate body are used as posture control tools to control the hoisting posture and angle in real time to prevent the plate body from swaying left and right or tilting backward. At the same time, the tracked vehicle 9 slowly follows the movement of the acrylic board 10; S5. Gear engagement and installation positioning: After the acrylic board 10 is hoisted, the acrylic board 10 moves along the circumferential direction to the predetermined position through the track beam 3 and is lowered onto the base 11 provided with a lifting air cushion, and then internal and external supports are used for positioning and fixing; When the board is successfully erected, the pulley on the track beam 3 is used to realize the rotation and sliding of the acrylic board 10 in the horizontal plane. After reaching the target installation port, the electric hoist 4 slowly lowers the hook, and the acrylic board 10 falls into the bottom lifting air cushion. After the board is initially in place, the inner and outer brackets are immediately installed for positioning and fixing; The inner tripod 14 is used to provide rigid support for the lateral stability of the acrylic plate 10. The outer adjustment screw 13 is set on the steel structure beam through actual measurement, and the tail supports the acrylic plate 10 for slow pushing and fitting adjustment. All contact points are provided with cushion layers to prevent damage to the plate body. S6, dismantling the sling: after confirming that the acrylic plate 10 is fixed, gradually loosen the hooks and dismantle the bottom sling 5 and the horizontal sling; S7. Lifting into place: Place a 100 mm high acrylic pad on the base 11 below the acrylic plate 10, remove the acrylic bottom lifting pad step by step, and the acrylic falls onto the acrylic pad.

[0026] The nylon belt is a 300mm wide orange standard lifting belt.

[0027] The acrylic plate 10 is bundled with standard lifting nylon belts, including three lifting straps 7 at the front and back, three bottom straps 5, and two upper and lower horizontal surrounding straps 6, wherein the bottom of the bottom strap 5 is provided with a rubber cushion.

[0028] The three front and rear lifting belts 7 are connected to the three electric hoists 4 respectively.

[0029] The inner and outer brackets include an inner standardized tripod 14 and a plurality of adjustment screws 13 on an outer steel frame.

[0030] The second hand chain hoist 12 is fixed on the expansion bolt on the top of the structural concrete column.

[0031] In order to ensure the structural safety and balanced force of the giant acrylic plate 10 during the hoisting process, a flexible sling strapping method is used for comprehensive protection and support; The sling adopts 300mm wide standard orange nylon lifting belt, which has high tensile strength and good flexibility, and is suitable for 10 types of vulnerable components of acrylic panels. Rubber pads are installed at the bottom of all slings in contact with the panel to prevent scratches from hard objects, increase friction and play a buffering and protective role. The specific bundling methods are as follows: Strap material and specifications: All use 300mm wide standard orange nylon lifting straps, which are highly flexible, have high load-bearing capacity, and do not cause hard damage to the surface of the acrylic plate 10; Rubber pads are added at the contact points between the bottom of the sling and the plate to prevent scratches or indentations caused by sharp corners or sharp edges, while increasing friction and improving lifting stability; Sling Arrangement: The overall arrangement adopts a multi-level and multi-point support method of "six hoists + three underlifts + two horizontals", which is specifically as follows: Hoisting slings (quantity × 6, 3 in the front and 3 in the back); It is arranged above the acrylic plate 10, evenly distributed, with three in each group, and is independently driven by 3 sets of 10t electric hoists 4 respectively to ensure synchronous hoisting. This sling is the main load-bearing structure for the entire hoisting and controls the vertical lifting; Underlift slings (quantity × 3); It is located at the bottom of the plate and directly supports the entire plate body. A rubber soft pad is added between the sling and the plate body to avoid sharp corner wear, playing a dual role of load-bearing support and shape stability; Horizontal circumferential slings 6 (1 set each for the upper and lower parts); It is arranged in the middle and lower part (at 5200mm from the bottom) and the upper part (at 8200mm from the bottom) of the plate body, and is bundled in a ring shape. Its main function is for lateral positioning and positioning of the underlift sling 5, preventing the plate body from swinging, offsetting or the bundling belt from sliding during hoisting. The horizontal sling does not bear the vertical load, but is crucial for the overall stability.

[0032] This bundling structure fully considers the characteristics of high quality and high risk of the giant acrylic plate 10, and realizes the comprehensive goals of "multi-point hoisting, flexible protection, synchronous control, and safe gear shifting". Its core advantage lies in significantly reducing the risk of plate body damage, improving the controllability of hoisting, and providing a good foundation for subsequent attitude control and precise installation.

[0033] The technical features not described in this invention can be realized by or adopted from the prior art, and will not be elaborated here. Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by those of ordinary skill in the art within the scope of the essence of the present invention should also fall within the protection scope of the present invention.
