Abstract
The utility model discloses an adjustable blade tip sheath. The adjustable blade tip sheath comprises a sheath body and fixed pieces. The sheath body is sleeved with clamping parts which are reserved at the two rear ends of a blade tip and used for clamping the fixed pieces. The fixed pieces enable the sheath body and a blade to be closely attached to each other, and the two ends of the sheath body are respectively provided with a rope penetrating hole for a mooring rope to penetrate through. The adjustable blade tip sheath can be compatible with various machines, the width of the adjustable blade tip sheath can be adjusted according to different specifications and models of blades, so that the adjustable blade tip sheath is applicable to hoisting of different blades, and the serviceable range of the adjustable blade tip sheath is broadened; besides, the adjustable blade tip sheath is simple in manufacturing process, convenient to operate, and capable of saving materials and lowering cost, and the width of the adjustable blade tip sheath can be adjusted quickly.
Description
Technical field
The utility model relates to a kind of sheath, is specifically related to a kind of adjustable blade tip sheath, guarantees the stability of blade in lifting process.
Background technique
In the lifting operation of wind-powered electricity generation industry blade, because wind field wind-force is larger, generally need to and fasten rope and control as ground at the tip of blade cover upper jacket, by ground staff, drawn, guarantee blade stablizing in lifting process.
At present, wind-powered electricity generation industry generally adopts fixing blade tip sheath, and sheath is directly overlapped to the suspension centre on blade; This fixed blade tip sheath can only corresponding a kind of specification blade, and wind field may have the blower fan of different types of machines, just has some limitations like this on sheath is used, can not compatible different types of machines.In order to raise the efficiency, reduce costs, design a kind of can the adjustable blade tip sheath of width extremely urgent.
Model utility content
For solving the deficiencies in the prior art, the purpose of this utility model is to overcome the defect of prior art, and the blade tip that a kind of width is adjustable, applied widely, cost is low sheath is provided.
In order to realize above-mentioned target, the utility model adopts following technological scheme:
A kind of adjustable blade tip sheath, comprise sheath body and fixed block, after above-mentioned sheath body is set in blade tip, two ends are left for gripping the clamping part of part, and above-mentioned fixing piece is by sheath body and blade is close to and the clamping part at sheath body two ends is all formed for the lacing hole through cable wind rope.
Aforementioned sheath body is made by rectangular terylene flame retardant waterproof canvas.
Aforementioned fixed block is clip, by light-duty aluminium, is made.
The thickness of aforementioned sheath bulk material is 1-2mm.
Aforementioned sheath body is installed on apart from leaf with 40-50cm place.
The width of aforementioned sheath body is 20cm.
Adjustable blade tip sheath of the present utility model, can compatible different types of machines, can carry out width adjustment for the blade of different size model, be applicable to the lifting of different leaves, increased using scope, and preparation process is simple, save material, reduce costs, easy to operate, can realize quickly the adjustment of sheath width.
Accompanying drawing explanation
Fig. 1 is the plan view of a kind of adjustable blade tip sheath of the present utility model;
Fig. 2 is the side view of a kind of adjustable blade tip sheath of the present utility model.
The implication of reference character in figure: 1, sheath body, 2, fixed block, 3, clamping part, 4, lacing hole.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is done to concrete introduction.
Referring to Fig. 1 and Fig. 2, a kind of adjustable blade tip sheath of the present utility model, comprise sheath body 1 and fixed block 2, wherein, sheath body 1 is preferably made by rectangular terylene flame retardant waterproof canvas, material thickness is 1-2mm, during use, be set within the scope of the suspension centre of blade tip, two ends are all left for gripping the clamping part 3 of part 2, fixed block 2 is close to sheath body 1 and blade and guarantee and do not slide, so, the clamping part 3 at the two ends of sheath body 1 has all formed for the lacing hole 4 through cable wind rope, lacing hole 4 is for stationary rope, be convenient to ground staff's traction, thereby guarantee the stability of blade in lifting process.
As a kind of concrete structure, fixed block 2 is clip, and quantity is two, is symmetrical arranged, by light-duty aluminium, made, and can people be manually-operable, realize clamping and loose unloading easy and conveniently.
In practical operation, preferably, sheath body 1 is installed on apart from leaf with 40-50cm place, and its width d is 20cm.
To sum up, adjustable blade tip sheath of the present utility model, can compatible different types of machines, can carry out width adjustment for the blade of different size model, be applicable to the lifting of different leaves, increased using scope, and preparation process is simple, save material, reduce costs, easy to operate, can realize quickly the adjustment of sheath width.。
More than show and described basic principle of the present utility model, major character and advantage.The technician of the industry should understand, and above-described embodiment does not limit the utility model in any form, and all employings are equal to replaces or technological scheme that the mode of equivalent transformation obtains, all drops in protection domain of the present utility model.
