Protective device for high-altitude object lifting hole of wind turbine generator

Abstract

The utility model discloses a protective device for a high-altitude object hanging hole of a wind turbine generator system. The protective device comprises an object hanging hole cover plate, a slide way and a traction device, the number of the sliding ways is two, the two sliding ways are arranged outside the object lifting hole in parallel, the two sliding ways are obliquely arranged, and notches are formed in the opposite sides of the two sliding ways. The object hanging hole cover plate is arranged between the two slideways, and the first opposite two ends of the object hanging hole cover plate are in sliding fit with the slideways respectively; the traction device is connected with the object lifting hole cover plate so as to pull the object lifting hole cover plate to slide upwards along the slide way; due to the fact that the sliding way is obliquely arranged, when the traction device is loosened, the lifting hole cover plate can automatically slide downwards along the sliding way under the action of gravity so as to seal the lifting hole, the high-altitude lifting hole of the wind turbine generator can be automatically closed after a lifted object passes through the lifting hole, and passing of a lifting chain is not affected; and objects falling from high altitudes or workers are effectively prevented from slipping and falling.

Description

Technical Field

[0001] The utility model relates to the technical field of wind power generation, in particular to a protective device for high-altitude hanging holes of a wind turbine set. Background Art

[0002] At present, the high-altitude lifting holes of wind turbines are protected by cover plates, that is, they are covered by hinges. When high-altitude lifting is required, the cover plate is manually lifted (similar to opening a door) to open the lifting hole for lifting operations. At this time, the cover plate is in an open state, which is prone to falling objects and even endangering personal safety. At the same time, the lifting hole is manually closed. If the lifting hole is not actively closed after the lifting is completed, there are also hidden dangers in the operation. Utility Model Content

[0017] Here, it should be noted that the functions and methods involved in the present invention are merely conventional adaptive applications of the prior art. Therefore, the improvement of the present invention on the prior art is essentially the connection relationship between the hardware, rather than the functions and methods themselves. That is, although the present invention involves some functions and methods, it does not include improvements to the functions and methods themselves. The description of the functions and methods in the present invention is to better illustrate the present invention so as to better understand the present invention.

[0018] The following embodiments of the technical solution of the utility model are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the protection scope of the utility model.

[0019] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by technicians in the field to which the utility model belongs.

[0020] See also Figure 1-2 The present application discloses a protective device for high-altitude hanging holes of a wind turbine, comprising a hanging hole cover plate 1, a slide 2 and a traction device; the slides 2 are two, the two slides 2 are arranged in parallel outside the hanging hole, and the two slides 2 are arranged at an angle, and notches are provided on opposite sides of the two slides 2; the hanging hole cover plate 1 is placed between the two slides 2, and its first opposite ends are respectively slidably matched with the slides 2; the traction device is connected to the hanging hole cover plate 1 to pull the hanging hole cover plate 1 to slide upward along the slide 2.

[0021] The present application sets a hanging hole cover plate 1, a slide 2 and a traction device, and the first two opposite ends of the hanging hole cover plate 1 are slidably fitted in the slide 2. Since the slide 2 is set outside the hanging hole, the hanging hole cover plate 1 can close the hanging hole after being installed on the slide 2, and can slide upward along the slide 2 to open the hanging hole through the traction of the traction device, and since the slide 2 is set inclined, when the traction device is released, the hanging hole cover plate 1 can automatically slide downward along the slide 2 under the action of gravity to close the hanging hole, so that the high-altitude hanging hole of the wind turbine set is automatically closed after the hanging object passes through the hanging hole without affecting the passage of the lifting chain, thereby effectively preventing falling objects from high altitude or workers from falling due to slipping.

[0022] The slideway 2 is installed outside the hanging hole, so that the hanging hole cover plate 1 can cover the hanging hole after installation to close the hanging hole; a notch is provided along the length direction of the slideway 2, so that the cross-sectional shape of the slideway 2 is C-shaped.

[0023] The hanging hole cover plate 1 is a flat plate structure, and pulleys are installed at its first two opposite ends, and the pulleys are slidably matched with the slideway 2 to realize the movement of the hanging hole cover plate 1 along the slideway 2. The pulleys can be installed on the lower sides of the first two opposite ends of the hanging hole cover plate 1, and can also be installed on the side walls of the first two opposite ends of the hanging hole cover plate 1.

[0024] In order to facilitate the passage of the lifting chain, a first through hole 11 for the passage of the lifting rope is provided on the lifting hole cover plate 1. When the lifting hole cover plate 1 covers the lifting hole, the lifting chain can still pass through the first through hole 11. The lifting hole cover plate 1 is provided with a second through hole 12 parallel to the slideway 2. One end of the second through hole 12 is connected to the first through hole 11, and the other end extends in the direction opposite to the traction direction. The second through hole 12 is an avoidance hole. When the lifting hole cover plate 1 slides upward under the action of the traction device, the lifting hole cover plate 1 is prevented from interfering with the lifting chain.

[0025] In order to connect the traction device, a traction hole 13 is provided on the hanging hole cover plate 1, and the traction device is connected to the traction hole 13.

[0026] In order to prevent the hanging hole cover plate 1 from drawing out the slideway 2 , an upper limit portion 21 is provided at the upper end of the slideway 2 , and a lower limit portion 22 is provided at the lower end of the slideway 2 .

[0027] During assembly, the lower end of the slide 2 is limited by the lower limit part 22, and the upper end is open. The hanging hole cover plate 1 can be slid into the slide 2 from the upper end of the slide 2, so that the hanging hole cover plate 1 and the slide 2 are slidably matched, and then the upper limit part 21 is installed on the upper end of the slide 2.

[0028] The upper limit portion 21 and the lower limit portion 22 may be any structure that can limit the hanging hole cover plate 1 from sliding out.
