Description

TECHNICAL FIELD

[0001] The utility model relates to the construction hoisting platform system of assembly type floating body for hydroelectric generation. BACKGROUND

[0002] The crane is arranged on the water platform in the water hoisting operation. The existing horizontal hoisting operation platform mainly comprises a ship type hoisting operation platform, a steel pipe frame type platform and an inflatable boat type platform, but these operation platforms have respective limitations. For example, the ship type hoisting operation has served as the main equipment for water hoisting and construction for a long time, but the moving conditions and flexibility are limited, and the ship type hoisting operation can only be used in deep water environment, otherwise the ship type hoisting operation cannot be moved to the position, thus the ship type hoisting operation cannot play a role in shallow water area or shore operation, and the cost is high, and many operation technical personnel are required. In addition, when the platform is completely stationary, there is no matching landing support to realize stability. The steel pipe frame type platform is also a commonly used operation platform, but the operation needs to be matched with a transport ship, and since the transport ship has the risk of colliding with or hitting the platform when the transport ship is close to the platform, the operation difficulty is increased; when the water bottom is relatively soft sandy soil, the sandy soil with water is unstable, the bearing capacity is poor, and it is difficult to ensure the stability and safety of the platform. In addition, since the river water level rises and falls, the platform cannot adapt to such changes. The inflatable boat is also used in the water hoisting operation, but since the inflatable boat is generally small, the load is difficult to meet the use requirement, and thus the inflatable boat has limited adaptation occasions.

DETAILED DESCRIPTION

[0033] Reference Figures 1-4 The utility model relates to a kind of water power generation with assembled floating body construction hoisting platform system, including air bag (for example, rubber air bag) 3, top beam 4, top beam connecting beam 5, cantilever type lifting hoisting frame 12, heavy lifting car 9, lifting trolley (lifting translation trolley) 11, lifting driving device (lifting driving for short), large car translation driving device 16, trolley translation driving device 17, horizontal plate protection 13, hydraulic driving device (hydraulic driving for short), landing support, safety rail 7 and anchoring cylinder 18 etc.

[0034] The air bag is longitudinally (in the extension direction of air bag) extended cylindrical in the inflated state, and one end of the air bag is provided with an inflator 2 and a gas pressure stabilizing alarm device. The number of air bags is three or more than three. Each air bag is parallel to each other and is sequentially and spacedly distributed transversely (in the direction perpendicular to the longitudinal direction on the platform plane). The outer edge of the air bags on both sides is located inside and close to the corresponding side edge of the platform (the specific distance is set according to the actual use requirement) to form a stable support for the platform and avoid damage to the edge of the air bag. The longitudinal ends of the air bags can be exposed from the corresponding side (or end) edge of the platform to obtain a more stable support effect. The buoyancy can be adjusted by cooperatively adjusting the air pressure of each air bag to adjust the size and distribution of the buoyancy, so as to stably support the platform at an appropriate height. At the same time, since multiple air bags are provided, when a certain air bag suddenly breaks, the other air bags can still bear the force without overturning the platform, so as to ensure the overall safety. The buoyancy of the air bag (the maximum buoyancy that the air bag can generate) should generally be greater than 2 times the load to ensure safety.

[0035] The platform frame is located above each air bag and is mainly composed of a top beam, a top beam connecting beam and two side beams (or end beams) 6. Each air bag is provided with a top beam located directly above the corresponding air bag for fixing the air bag and receiving the buoyancy of the air bag.

[0036] The top beam itself is a hollow structure seal body, has a larger self-floating function, and 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-shaped structure 19, which is generally a longitudinally extending column, and the bottom surface is arc-shaped (cylindrical), which is in close contact with the top surface of the air bag below, for bearing / transferring the buoyancy of the air bag. The bottom surface of the arc-shaped structure is consistent with the surface curvature of the air bag (in the inflated state), so that the top surface of the air bag is in close contact with the bottom surface of the arc-shaped structure at the bottom of the top beam, and the contact area (the area of the region where the two are in contact) should meet the allowable yield strength of the air bag rubber (or other air bag materials). The top beam itself bears the top force of the floating body and the pressure of the crane truck, and the deformation should be within the allowable range. The end of the top beam is welded with an equipment connecting plate, and is provided with screw holes for installing the top beam connecting beam and water drive machine, etc. The arc-shaped structure at the bottom of the top beam is welded with a plurality of pairs of tight banders (or called binding rope devices) 15 on both sides (transverse sides). The spacing (longitudinal spacing) of the tight banders can be 80 cm, and the binding belt for binding the air bag is wound around the bottom surface of the air bag, and the two ends are connected to the tight banders on both sides, respectively, and the binding belt is moderately tightened / tied, so that the air bag is bound together with the arc-shaped structure / top beam.

[0037] According to actual needs, lifting rings can be welded on the top beam or the arc-shaped structure, and auxiliary facilities such as anchor cylinders (or anchor rope columns) and safety rail connecting columns can be provided according to actual needs.

[0038] The top beam connecting beam is arranged at both ends of the top beam and fixedly connected (for example, threaded connection, or welding, etc.) with the corresponding end of each top beam, so that the force of each floating body forms a planar support force, and the top beam connecting beam is uniformly provided with support steel pipes of wooden beams, which facilitates the force transmission and fixation of the wooden beams parallel to the floating body. The top beam, connecting beam and wooden beam are connected together to form a wooden board (flat plate) bracket and a mortise fixed point, so that the whole platform is safe and stable.

[0039] The crane preferably adopts a single-column single-arm structure cantilever crane, and the base of the crane is fixed on the top beam of the middle floating body. The arm can rotate 360 0The crane can also be a portal crane, the two side girders of which are arranged on the top beams of the two air bags at the outermost lateral sides, and can be used to hoist larger weights. The crane of either type is designed with mechanisms for trolley movement, cart movement and lifting, the trolley rails 10 and the cart rails 14 are arranged on the platform (platform frame) according to the operation requirements, and are provided with stops 8 and the like according to the actual requirements, and these mechanisms are provided with electric driving devices, such as electric motors for driving the cart and trolley to move. The crane frame upright columns are provided with a screw connection according to the prior art, and can be manually or electrically laid flat at any time when not used for hoisting, and can be manually erected for use again. The power of the crane is applied to the footings to reduce the center of gravity and improve stability. The trolley movement and the lifting of the hook are driven by steel wires, and the relevant steel wires are wound and released by setting appropriate winches.

[0040] The hydraulic drive is arranged at the end of the middle top beam, and is driven by a methanol internal combustion engine. When the platform is stopped, the generator supplies power for other operations, achieving one machine with multiple uses, without oil leakage pollution, and without the need to pull a line from the power grid, reducing safety hazards.

[0041] The platform frame is provided with a trapezoidal screw column 1 at each corner, which forms a floor support. Specifically, the trapezoidal screw columns are arranged at the ends of the top beams of the two floating bodies at the outer lateral sides (the outermost lateral sides). The height (or length) of the trapezoidal screw column can be adjusted by rotation, so that the column falls to the ground, and the lower end (the falling end) of the column is provided with a flat plate for expanding the contact area. When the column may be suspended and not under stress, the torque motor will automatically compensate for the force, thereby ensuring that the four columns (trapezoidal screw columns at the corners) of the platform are always under stress, thereby achieving constant stability.

[0042] Anchor rope columns are designed in four directions. When it is predicted that there may be a large lateral force, a rope can be tied on the anchor rope columns in multiple directions, and the outer end of the rope is pulled tight with a pre-buried anchor pile or a distant tree pile, etc., to facilitate the stability of the platform.

[0043] The horizontal boards are made of wooden boards, which are laid on the platform frame to form the floor of the platform. The covered area of the wooden boards can be set according to actual needs, and part of the wooden boards can be removed at will.

[0044] Mechanical operations can be performed at any position in the middle.

[0045] Due to the large self-provided buoyancy of the platform, excavators, pile drivers and materials can also be placed on the platform and transported to the target position on the water.

[0046] The utility model discloses each preferred and optional technical means, except special explanation and one preferred or optional technical means is another technical means's further limitation, can be arbitrary combination, forms several different specific embodiment.
