Description
Technical Field
The invention belongs to the technical field of wind driven generators, and particularly relates to a nacelle hanging opening structure of a wind driven generator set and application of the nacelle hanging opening structure.
Background
The center of the nacelle drop opening is typically located at the rear end of the nacelle, offset from the tower centerline. A crane for the interior of the engine room is arranged right above the object hanging opening, a cover plate capable of being opened is arranged at the object hanging opening, and a guide chain of the crane hoists objects from the object hanging opening.
The inventor knows that in the existing generator set cabin, one object hanging opening is arranged on a machine frame, a second object hanging opening is arranged on a cabin cover bottom plate below the machine frame, and the projections of the two object hanging openings in the vertical direction are overlapped. When hoisting is needed, the operation steps are as follows: sequentially opening the cover plates at two object hanging openings from top to bottom, lowering a guide chain from the object hanging openings, lifting objects, closing the cover plate below the objects after entering the cabin, and closing the cover plate above the objects after reaching the rack.
A certain height is formed between the rack and the bottom plate of the cabin cover, and in the hoisting process, each complete hoisting process requires an operator to hoist the rack twice to complete the opening and closing of the upper cover plate and the lower cover plate. Although in safety regulations the cover plate below must be closed after lifting the object into the nacelle cover to reduce the risk of falling. However, in practical engineering, an operator generally moves on the upper surface of the machine frame, and under the motivation of saving time, the operator can put the cover plate at the position of the cabin cover in a long-time opening state, and when the cover plate does not need to be hoisted, the operator can forget to close the lower cover plate.
In the lifting process, a worker stands beside a lifting port of the rack all the time, constantly observes the conditions that the guide chain is lowered and the object is lifted, and risks that the worker falls from the lifting port exist.
Therefore, the inventor believes that the structural arrangement of the object hanging opening at the existing frame can not ensure the safety when an operator does not close the object hanging opening at the cabin cover for a long time due to time saving.
Disclosure of Invention
The invention aims to provide a wind generating set cabin lifting opening structure and application thereof, which can reduce the falling risk caused by the fact that an operator does not close a lifting opening cover plate at a cabin cover.
In order to achieve the purpose, the scheme provides a wind generating set cabin lifting opening structure which comprises a base frame, wherein a lifting opening is formed in the base frame, a cover plate is arranged at the lifting opening and is hinged to the base frame, and the cover plate can rotate along a hinge joint of the cover plate and the base frame to complete opening and closing of the lifting opening.
The object lifting port is provided with a horizontal guardrail which can slide in a reciprocating manner along a set horizontal direction so as to realize the opening and closing of the object lifting port.
The horizontal guardrail is arranged below the cover plate, a lifting appliance opening is formed in the horizontal guardrail, and the lifting appliance opening is used for allowing a steel wire rope and a lifting appliance to pass through.
Furthermore, one end of the cover plate is hinged with the frame through a hinge.
Furthermore, a fixed frame is arranged on the side wall of the object hanging opening, the fixed frame and the object hanging opening are the same in outer contour shape, and the outer contour size of the fixed frame is the same as the size of the object hanging opening;
the fixed frame is internally provided with a guide groove which is matched with a guide piece in the horizontal guardrail for use so as to realize the guide of the horizontal guardrail during sliding.
Furthermore, the fixed frame comprises two U-shaped plates with opposite openings, the two U-shaped plates are fixedly connected through a connecting plate, the U-shaped plates and the connecting plate are combined to form a square frame structure, and the openings of the U-shaped plates form the guide grooves.
Furthermore, a guide bearing is arranged in the guide groove, the rotating axis direction of the guide bearing is perpendicular to the extending direction of the guide groove, and the rotating axis direction of the guide bearing is horizontally arranged.
Further, horizontal guardrail includes the grid net, the both sides of grid net are passed through the backup pad and are supported, the extending direction of backup pad is parallel with horizontal guardrail's direction of advance, the screw rod is installed to the lower extreme of backup pad, the outside cover of screw rod is equipped with the bearing
Furthermore, the lifting appliance port penetrates through the grid net in the vertical direction, and the lifting appliance port penetrates through one side wall of the grid net in the horizontal direction.
The invention also provides a wind generating set, which comprises the wind generating set cabin hanging opening structure.
The invention has the beneficial effects that:
the opening and closing of the object hanging opening are completed by pushing and pulling the horizontal guardrail in a mode that the horizontal guardrail is arranged at the object hanging opening on the rack; meanwhile, the sling opening arranged on the horizontal guardrail can ensure the steel wire rope and the sling to pass through when the horizontal guardrail is closed, and the sling opening is in a closed state before articles pass through the sling opening at the rack.
Even if the operator enables the object lifting opening at the cabin cover to be in a long-time opening state for the reason of saving time, the object lifting opening at the rack is in an opening state only when objects pass through the object lifting opening, and the object lifting opening is completely in a closing state at other times; the risk of workers caused by not closing the hanging opening below is greatly reduced.
The openings of the two U-shaped plates are used as guide grooves, so that the support of the fixed frame on the horizontal guardrail can be realized while the guide function of the fixed frame is completed.
The grid net is used as the horizontal guardrail, so that the monitoring of operators on the lifted objects outside the cabin can be realized under the condition that the horizontal guardrail closes the object lifting opening.
