Description

Technical Field

[0001] The invention relates to an assembled floating body construction hoisting platform system for hydroelectric power generation. Background Art

[0002] The water hoisting operation sets the crane on the water platform. The existing horizontal hoisting operation platform mainly consists of ship-type hoisting operation platform, steel pipe frame platform and inflatable boat platform, but these operation platforms have their own limitations. For example, the ship-type hoisting operation has served as the main equipment for water hoisting and construction for a long time, but its movement conditions and flexibility are limited. It must be used in a deep water environment, otherwise it cannot be moved into place, so it cannot play a role in shallow water or shore operations, and the cost is high, so many operating technicians are required. In addition, when the platform is completely stationary, there is no matching ground support to achieve stability. The steel pipe frame platform is also a commonly used operation platform, but it often requires transport ships to cooperate with the operation. Since there is a risk of collision or collision with the platform when the transport ship approaches the platform, the difficulty of the operation is increased; when the bottom of the water is relatively soft sandy soil, it is difficult to ensure the stability and safety of the platform because the sand with water is unstable and has poor bearing capacity. In addition, since the river water elevation will fluctuate, the platform cannot adapt to such changes. Inflatable boats are also used in water lifting operations, but because inflatable boats are generally small and their loads are difficult to meet the requirements of use, their adaptability is limited. Summary of the invention

[0003] The present invention provides an above-water hoisting operation platform which can be well adapted to operations in shallow water areas.

[0004] The technical solution of the present invention is: an assembled floating construction hoisting platform system for hydropower generation is provided with a plurality of air bags, the tops of the air bags are supported by top beams, and the top beams are connected by top beam connecting beams to form a frame structure constituting a platform frame (the main part of the platform frame).

[0005] Lifting equipment for lifting operations may be arranged on the platform / platform frame.

[0006] Furthermore, the extension direction of the top beam is consistent with the extension direction of the airbag, and both extend longitudinally. When in use, the extension direction of the airbag can be consistent with the direction of the river (or river bank) to reduce the impact of water flow and facilitate the stability of the platform.

[0007] Preferably, an arc structure (airbag connecting structure) for connecting the airbag is provided at the bottom of the top beam, the bottom surface of the arc structure is an arc surface consistent with the top surface of the airbag, and the top surface of the airbag is attached to the bottom surface of the arc structure.

[0008] Preferably, the airbag is tied to the arc-shaped structure by means of straps, and belt tighteners for fixing the straps are provided (for example, welded) on both sides of the component (integrated structure) consisting of the top beam and the arc-shaped structure.

[0009] Furthermore, the belt tighteners located on both sides of the component consisting of the top beam and the arc-shaped structure are distributed at intervals in the longitudinal direction over the entire longitudinal area of ​​the top beam.

[0010] Preferably, both longitudinal ends of the airbag extend from corresponding ends of the platform frame to facilitate stability.

[0011] Furthermore, the number of the top beam connecting beams is at least two, and the two top beam connecting beams are respectively located at the two ends of the top beam and connected to the corresponding ends of each top beam. Both ends of the top beam connecting beam are connected to side beams, and the side beams are parallel to the top beam and located on the outside of all the top beams on the corresponding sides.

[0012] Preferably, all the airbags are located laterally inside the platform frame (the side beams on the corresponding sides).

[0013] Preferably, an end portion (usually one end) of the airbag is provided with (connected with) an inflation device.

[0014] Furthermore, the end of the airbag may be connected to an air pressure stabilization alarm device.

[0015] Preferably, the number of airbags is not less than 3, so as to prevent the platform from overturning when a single airbag is damaged.

[0016] Preferably, the top beam adopts a hollow structure sealing body.

[0017] Furthermore, a lifting ring is welded on the component consisting of the top beam and the arc structure.

[0018] Furthermore, the side beams and the top beam connecting beam are provided with (for example, welded with, or threaded with) anchor rope columns and safety railings (or connecting columns of safety railings).

[0019] Wooden beam support structures are evenly distributed (for example, welded) on the top beam connecting beam, so that the wooden beams can be installed on the platform frame through the corresponding wooden beam support structures. The top beam, the top beam connecting beam and the wooden beam are connected as a whole to form a wooden board (or a flat board of other materials) bracket and anchor points, and a waterproof flat board (for example, a wooden board treated with waterproofing) can be laid on the platform according to actual needs.

[0020] Preferably, a plurality of adjustable columns are installed on the platform frame.

[0021] Preferably, a flat plate for expanding the supporting area is provided at the bottom end of the adjustable column.

[0022] The number and distribution of the columns are set according to actual needs, and can be distributed at intervals on each frame of the platform frame. Usually, columns should be provided at the four corners of the platform frame.

[0023] Preferably, a hydraulic driving device for driving the platform to move on water is installed on the platform frame.

[0024] Preferably, the hydraulic drive device is arranged at the end of the top beam located in the middle.

[0025] Furthermore, the lifting equipment may be a cantilever crane with a single-column and single-arm structure.

[0026] Furthermore, the lifting equipment may also be a gantry crane.

[0027] The beneficial effects of the present invention are as follows: since a plurality of airbags are supported below the platform frame, the platform system can float stably on the water surface; since an arc structure is provided at the bottom of the top beam, the contact area is enlarged, which helps to ensure stability and reliability, and helps to extend the service life; since the airbags are fixed on the arc structure by means of strapping, it is adapted to the characteristics of the airbags and ensures that they are still effective when the airbag volume changes; since the airbag inflation volume can be adjusted according to the actual state, the balance between the airbags can be achieved, and the total buoyancy can be adjusted to adapt to different load conditions; since the platform frame is prepared using steel beams, the structural strength of the platform is guaranteed, and the platform can be moved on water by a hydraulic drive device, which facilitates the platform setting and position adjustment, and facilitates on-site operations; since adjustable columns are provided and a large-area flat plate support is provided at the bottom of the columns, it helps to stabilize the platform and can adapt to different underwater geological conditions.

[0028] The invention can be well adapted to water hoisting operations in shallow water areas, and can be used for hydroelectric power generation hoisting or other suitable occasions. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] See also Figure 1-Figure 4 The present invention relates to an assembled floating construction hoisting platform system for hydropower generation, comprising an air bag (for example, a rubber air bag) 3, a top beam 4, a top beam connecting beam 5, a cantilever lifting and hoisting frame 12, a lifting trolley 9, a lifting trolley (lifting translation trolley) 11, a lifting drive device (referred to as lifting drive), a trolley translation drive device 16, a trolley translation drive device 17, a waterproof flat plate 13, a hydraulic drive device (referred to as hydraulic drive), a ground support, a safety railing 7 and an anchoring cylinder 18, etc.

[0032] The airbag is in a cylindrical shape extending longitudinally (the extension direction of the airbag is the longitudinal direction) when inflated. An inflating device 2 and an air pressure stability alarm device are provided at one end of the airbag. The number of airbags is 3 or more than 3. The airbags are parallel to each other and are spaced in sequence in the transverse direction (the direction perpendicular to the longitudinal direction on the platform plane is the transverse direction). The outer edges of the airbags on both sides of the transverse direction are located inside the corresponding side edges of the platform and close to the corresponding side edges of the platform (the specific distance is set according to actual use requirements) to form a stable support for the platform and avoid external damage to the edge of the airbag. The longitudinal ends of the airbag can be exposed from the corresponding side (or corresponding end) edge of the platform to obtain a more stable support effect. The buoyancy size and buoyancy distribution can be adjusted by coordinating the air pressure of each airbag to stably support the platform in a horizontal state at an appropriate height. At the same time, since multiple airbags are provided, when a certain airbag suddenly ruptures, the other airbags still bear the force without causing the platform to overturn, which can ensure overall safety. The buoyancy of the airbag (the maximum buoyancy that the airbag can generate) should usually be greater than 2 times the load to ensure safety.

[0033] The platform frame is located above each airbag, and is mainly connected by a top beam, a top beam connecting beam, and side beams (or end beams) 6 on both sides. Each airbag is provided with a top beam, which is located directly above the corresponding airbag and is used to fix the airbag and receive the buoyancy of the airbag.

[0034] The top beam itself is a hollow structure sealed body with a large self-buoyancy function. It can supplement the buoyancy in extreme cases to facilitate the floating and stability of the platform. The bottom of the top beam is provided with (connected with) an arc structure 19. The arc structure is generally in the shape of a longitudinally extending column, and the bottom surface is arc-shaped (cylindrical), which fits the top surface of the airbag below it and is used to bear / transmit the buoyancy of the airbag. The curvature of the bottom surface of the arc structure is consistent with the curvature of the surface of the airbag (inflated state), so that the top surface of the airbag and the bottom surface of the arc structure at the bottom of the top beam are closely attached to each other, and the size of the contact area (the area of ​​the area where the two are attached together) should meet the allowable yield strength of the airbag rubber (or other airbag materials). The top beam itself must bear loads such as the top force of the floating body and the pressure of the crane vehicle, and the deformation should be within the allowable range. The end of the top beam is welded with an equipment connecting plate, which is equipped with screw holes for installing the top beam connecting beam and water-driven equipment. Several pairs of belt tighteners (or rope tieers) 15 for tying up the airbag are welded on both sides (lateral sides) of the arc-shaped structure at the bottom of the top beam. The spacing of the belt tighteners (longitudinal spacing) can be 80cm. The straps for tying up the airbag go around the bottom of the airbag, and the two ends are respectively connected to the belt tighteners on both sides. The straps are appropriately tightened / fastened, thereby tying up the airbag and the arc-shaped structure / top beam.

[0035] According to actual needs, lifting rings can be welded on the top beam or the arc-shaped structure, and ancillary facilities such as anchoring columns (or anchoring rope columns) and connecting columns for safety railings can be set according to actual needs.

[0036] The top beam connecting beam is set at both ends of the top beam and fixedly connected with the corresponding ends of each top beam (for example, threaded connection, or welding, etc.), so that the force of each floating body forms a plane bearing force. The top beam connecting beam is evenly distributed with supporting steel pipes of wooden beams, which is convenient for transmitting force and fixing wooden beams parallel to the floating body. The top beam, connecting beam and wooden beam are connected together to form a wooden board (flat board) bracket and mortise points, making the overall platform safe and stable.

[0037] The crane is preferably a cantilever crane with a single-column and single-arm structure. The base of the crane is fixed on the top beam of the middle floating body, and the arm can be moved 360 degrees. 0Rotation, small footprint, large operating area. The crane can also use a gantry crane. The ground beams on both sides of the gantry crane (the gantry) are respectively arranged on the top beams of the two air bags on the outermost side in the horizontal direction, which can be used to lift heavier objects. Both types of cranes are designed with mechanisms for trolley operation, large vehicle operation and lifting. The trolley rails 10 and large vehicle rails 14 are arranged on the platform (platform frame) according to the operating requirements, and the stoppers 8 are set according to actual needs. These mechanisms are all equipped with electric drive devices, for example, motors used as large vehicle translation drive devices and trolley translation drive devices. The crane frame columns are provided with twisted connections according to the existing technology. When not used for lifting, they can be manually or electrically laid flat at any time, and can be manually raised and used when used again. The power of the crane is applied to the ground feet to help lower the center of gravity and improve stability. The movement of the trolley and the lifting and lowering of the hook are driven by wire ropes, and the winding and release of the relevant wire ropes are achieved by setting a suitable winch.

[0038] The hydraulic drive device is at the end of the middle top beam, and is driven by a methanol internal combustion engine. When the platform stops, the generator supplies power for other work, achieving multiple uses of one machine without causing oil leakage pollution, and without having to pull wires from the power grid, reducing safety hazards.

[0039] Trapezoidal screw columns 1 are provided at the four corners of the platform frame to form a ground support. Specifically, the trapezoidal screw columns are respectively arranged at the two ends of the top beams of the two floating bodies on the transverse outer side (outermost side). Therefore, the height (or length) of the trapezoidal screw column can be adjusted by rotation to make the column land, and the lower end (ground end) of the column is equipped with a flat plate for expanding the contact area. When the column may be suspended in the air without force, the torque motor will automatically compensate for the force, thereby ensuring that the four columns of the platform (the trapezoidal screw columns at the four corners) are always under force, so as to achieve stability.

[0040] Anchoring rope columns are designed in four directions. If it is predicted that a large lateral force may occur, ropes can be tied to the anchoring rope columns in multiple directions, and the outer ends of the ropes can be tightened to pre-buried anchor piles or distant tree stumps to facilitate the stability of the platform.

[0041] The waterproof flat plate is made of wooden boards, which are laid on the platform frame to form the floor of the platform. The area covered by the wooden boards is set according to actual needs, and some of the wooden boards can be removed at will.

[0042] Any position in the middle can cooperate with mechanical operation.

[0043] Since this type of platform has great self-contained buoyancy, excavators, pile drivers, and materials can also be placed on the platform and transported to the target location on the water.

[0044] Unless otherwise specified or when one preferred or optional technical means is a further limitation of another technical means, the preferred and optional technical means disclosed in the present invention can be arbitrarily combined to form several different specific implementation methods.
