Description

Safety protection device for object hanging opening of cabin of wind generating set

Technical Field

The utility model relates to the technical field of wind generating set cabin hanging safety, in particular to a safety protection device for a wind generating set cabin hanging opening.

Background

In the prior art, a hanging opening of a large-scale wind generating set cabin is also a passage for personnel to get out of the cabin, so that the hanging opening is required to have no obstacle when the personnel get out of the cabin, and the obstacle or the warning is required to be arranged for protecting the safety of the personnel when the personnel get out of the cabin. Therefore, it is necessary to provide a safety device with warning and blocking functions, when hanging objects, the safety device is in an open position, so that warning personnel do not get close to the safety device and can block personnel from entering a dangerous area, and when the safety device is taken out of a cabin, the safety device is in a retracted state, the warning function of a hanging object opening is cancelled, a handrail is removed, and the personnel can be ensured to smoothly pass through the position and go out of the cabin for operation. As shown in the simplified diagram of fig. 1, a large wind turbine generator system nacelle 01 is generally designed with a crane 02 to facilitate replacement of components in the nacelle 01, a hole for the crane 02 to enter and exit is formed at the tail of the nacelle 01, and a tower is shown as 05 in the diagram; as shown in a schematic view of fig. 2, when lifting an object, the crane 02 moves to a lifting port outside the nacelle 01 through a fixed guide rail 03 above the crane 02 to perform a lifting operation, and when the object is not lifted, the crane 02 cannot stand on the lifting platform 04, and when the object is not lifted, the crane moves to a predetermined position inside the nacelle 01, and at the same time, a worker can enter and exit the nacelle 01 through the lifting platform 04 to perform operations such as material transportation and equipment maintenance inside and outside the nacelle 01.

SUMMERY OF THE UTILITY MODEL

The utility model aims to overcome the defects of the prior art and provides a safety protection device for a hanging opening of a cabin of a wind generating set, which is simple and reliable in structure and convenient to operate.

In order to achieve the purpose, the technical scheme provided by the utility model is as follows: the utility model provides a wind generating set cabin hangs thing mouth safety device, includes panel, first pivot, second pivot, limiting plate and blocks the piece, wherein, the limiting plate is installed on the thing platform guardrail that hangs in cabin, the one end of panel is articulated on the limiting plate through the first pivot that is on a parallel with the limiting plate, can carry out the free swing around first pivot, the other end of panel is cantilever end, block the second pivot that passes through the perpendicular to limiting plate and articulate on the limiting plate, can carry out 360 rotations around the second pivot, it has the interval that can hold panel thickness to reserve between piece and the limiting plate, treat that the panel swings back in this interval, will block rotatory position to down of piece, can restrict the panel and can not take place the swing in this interval to block personnel through the panel and go out the cabin.

Further, the second rotating shaft is designed to be a hollow structure.

Furthermore, the word of 'no pass is hung when being hoisted' is carved on the panel and is used for reminding people of danger of hanging objects in front.

Compared with the prior art, the utility model has the following advantages and beneficial effects:

through the cooperation that stops between piece and the spacing board, can realize can not taking place the swing with the panel restriction in the regulation position to stop personnel to go out the cabin, personnel's safety when in order to ensure to hang the thing, and be carved with "hoist and mount and forbid current" the typely on the panel, also can effectively remind operating personnel place ahead to hang the thing dangerous, then remove the restriction to the panel, can allow personnel to go out the cabin. In a word, the device has the advantages of simple and reliable structure, convenient operation, light weight (for example, the second rotating shaft is designed into a hollow structure) and the like, has practical application value and is worth popularizing.

Detailed Description

The present invention will be described in further detail with reference to examples and drawings, but the present invention is not limited thereto.

As shown in fig. 3 to 5, the embodiment discloses a safety protection device for a hanging object opening of a cabin of a wind generating set, which includes a panel 1, a first rotating shaft 2, a second rotating shaft 3, a limiting plate 4 and a blocking member 5, wherein the limiting plate 4 is installed on a guardrail 6 of a hanging object platform of the cabin, one end of the panel 1 is hinged on the limiting plate 4 through the first rotating shaft 2 parallel to the limiting plate 4 and can swing freely around the first rotating shaft 2, the other end of the panel 1 is a cantilever end, the blocking member 5 is hinged on the limiting plate 4 through the second rotating shaft 3 perpendicular to the limiting plate 4 and can rotate 360 degrees around the second rotating shaft 3, in order to reduce weight, the second rotating shaft 3 is designed to be a hollow structure, a space capable of accommodating the thickness of the panel 1 is reserved between the blocking member 5 and the limiting plate 4, after the panel 1 swings into the space, the blocking member 5 is rotated to a downward position, can will not take place the swing with panel 1 restriction in this interval to block personnel through panel 1 and go out the cabin, and still be carved with "hoist and mount forbidding the current" word on panel 1, also can remind personnel the place ahead to hang the thing dangerous.

When the object is hung, the limiting panel 1 is in the position shown in fig. 3, so that the personnel can be warned and stopped from getting out of the cabin during the object hanging operation, and the danger is avoided; when the object hanging operation is completed, the crane is moved to a specified position in the cabin through the guide rail, at the moment, under the condition that safety measures are prepared, the limitation on the panel 1 can be removed, the panel 1 is swung to a position parallel to the object hanging platform guardrail 6, and the passing of personnel is not influenced.

The above embodiments are preferred embodiments of the present invention, but the present invention is not limited to the above embodiments, and any other changes, modifications, substitutions, combinations, and simplifications which do not depart from the spirit and principle of the present invention should be construed as equivalents thereof, and all such changes, modifications, substitutions, combinations, and simplifications are intended to be included in the scope of the present invention.
