Description

Cabin hoist and mount swift current rope protection device

Technical Field

The utility model relates to a jack-up lifting device's technical field especially relates to a cabin hoist and mount swift current rope protection device.

Background

In the existing hoisting project of the wind driven generator in China, the cabin of the wind driven generator is installed at the top of a fan, the height of the top of the fan is generally more than 90m, and the high-altitude wind power greatly affects the opposite installation of the cabin. In order to ensure that the cabin can be quickly and stably positioned in a facing mode, a sliding rope is usually tied to the cabin, and ground personnel stabilize the orientation of the cabin by dragging the sliding rope so as to quickly align the cabin in a positioning mode. When the engine room is hoisted, high-altitude wind power is high, the dragging force required by the ground sliding rope is increased, the position where the sliding rope is fastened is often in contact friction with sharp corners of the engine room, the sliding rope is easily cut off, the effect of the sliding rope is failed, and great potential safety hazards are caused to the hoisting.

Disclosure of Invention

The utility model discloses aim at solving prior art's not enough, prevent that the swift current rope from being cut off and causing serious consequence, and provide a cabin hoist and mount swift current rope protection device, this protection device installs simply, the fastening is reliable, plays effectual guard action to the swift current rope, has prolonged the life of swift current rope, has improved the security performance of swift current rope.

The utility model discloses a realize above-mentioned purpose, adopt following technical scheme:

the utility model provides a cabin hoist and mount swift current rope protection device, includes the protective sheath of demountable installation in one of them bolt hole of cabin butt joint face circumference range, is equipped with the through-hole that supplies the swift current rope to pass in the protective sheath, and the swift current rope is tied after passing the through-hole and is hung on the inside fixed point in cabin, and the one end of through-hole back to the inside fixed point in cabin is the tubaeform opening.

The protective sheath is the T shape structure of constituteing by dog and a grafting section of thick bamboo, and the dog laminating is installed the backstop ring after passing the bolt hole at one side of cabin inside fixed point dorsad in the cabin butt joint face at the grafting section of thick bamboo.

The flared opening is located inside the stopper.

The outer wall of the inserting cylinder is provided with external connecting threads, the inner wall of the stop ring is provided with internal connecting threads, and the stop ring is detachably mounted with the inserting cylinder through the internal connecting threads and the external connecting threads.

The utility model has the advantages that: the utility model discloses changed the using-way of swift current rope in the past, with swift current rope and the direct friction conversion of metal edges and corners in the past smooth rope and protection device's flexible friction, play the effect of protection swift current rope, prolonged the life of swift current rope, improved the security.

the following detailed description will be made in conjunction with embodiments of the present invention with reference to the accompanying drawings.

Detailed Description

The invention will be further explained with reference to the following figures and examples:

as shown in fig. 1 to 4, a device for protecting a hoisting sling of a nacelle comprises a protective sleeve 1 which is detachably mounted in one of bolt holes 5 circumferentially arranged on a butt joint surface 4 of the nacelle, wherein a through hole 2 for the sling 6 to pass through is arranged in the protective sleeve 1, the sling 6 is tied and hung on a fixed point 7 inside the nacelle after passing through the through hole 2, and one end of the through hole 2, which is back to the fixed point 7 inside the nacelle, is a horn-shaped opening 3.

The protective sleeve 1 is a T-shaped structure consisting of a stop dog 11 and an insertion tube 12, the stop dog 11 is attached to one side of the butt joint surface 4 of the cabin, which is back to the fixed point 7 in the cabin, and the insertion tube 12 penetrates through the bolt hole 5 and then is provided with a stop ring 13.

The flared opening 3 is located inside the stop 11.

An external connecting thread is arranged on the outer wall of the plug-in cylinder 12, an internal connecting thread is arranged on the inner wall of the stop ring 13, and the stop ring 13 is detachably mounted with the plug-in cylinder 12 through the internal connecting thread and the external connecting thread.

In the hoisting construction operation of a certain wind generating set cabin, after the sliding rope 6 is frequently used, the strand of the outer layer is broken, the high-altitude operators are relieved from checking the sliding rope 6, and ground personnel have the accident that the whole sliding rope 6 is broken when dragging the sliding rope 6 hard, so that the dragging personnel are damaged by falling. And because the engine room shakes under the action of inertia, the engine room opposite-opening installation work cannot be completed smoothly, and a new sliding rope 6 needs to be tied and hung after the lifted engine room descends to the ground again, so that the construction period is delayed, the construction safety cannot be guaranteed, and unnecessary negative effects are caused. In the subsequent hoisting operation process, the occurrence of the breakage event of the sliding rope 6 can be avoided by adopting the nacelle hoisting sliding rope protection device, so that the safety of personnel and equipment in the nacelle hoisting process is ensured. The sliding rope 6 penetrates through the cabin hoisting sliding rope protection device to be tied and hung on a fixed point 7 in the cabin, and the direction of the cabin during hoisting is adjusted by dragging the sliding rope 6. The trumpet-shaped opening 3 is beneficial to protecting the sliding rope 6, avoids being separated by sharp parts, converts the direct friction between the sliding rope 6 and the metal edges and corners into the flexible friction between the sliding rope 6 and a protecting device in the past, plays a role in protecting the sliding rope 6 and ensures that the engineering construction is safer.

The present invention has been described above with reference to the accompanying drawings, and it is obvious that the present invention is not limited by the above embodiments, and various improvements made by the method concept and technical solution of the present invention or directly applied to other occasions without improvement are all within the protection scope of the present invention.
