Description
Technical field
The present invention relates to a kind of fan blade maintenance unit more particularly to a kind of fan blade surface ice sheet removal devices.
Background technique
Fan blade accounts for about the 15%-20% of blower totle drilling cost, at present the blade of large-scale wind driven generator substantially by
Composite material is constituted, and composite material content is usually more than 90%.According to statistics, fan blade size is every increases 6%, the wind energy of capture
12% can be increased.The original design intention of blade is to obtain the balance of aerodynamic efficiency and structure design.The selection of material and technique is determined
The final actual (real) thickness of blade and cost are determined.Structure designer is in the work how to combine design principle and manufacturing process
Play key player in work, it is necessary to find out guarantee performance and reduce the optimal case between cost.Blade stress analysis: blade
The thrust driving blade of upper receiving rotates.The distribution of thrust is not distribution uniform but proportional to length of blade, leaf tip
The thrust of receiving is greater than blade root.The north or high mountain wind power plant one are easy to freeze or snow to winter, it will the shape on blade
At coating, such as cleaning can make blade loading be more than design load not in time, will will cause blade fault when severe or fracture, and make
At heavy economic losses.
Summary of the invention
According to the above technical problem, the present invention provides a kind of fan blade surface ice sheet removal device, it is characterised in that packet
Lifting bottom plate, the outer guardrail of lifting are included, guardrail, elastic ring in lifting, cloth is accepted, heating device, telescopic cylinder, spring, removes crampon,
The lifting bottom plate generally rectangular-ambulatory-plane, the lifting plate outer side, which is equipped with, lifts outer guardrail, is equipped on the inside of the lifting bottom plate
Interior guardrail is lifted, guardrail middle position is equipped with elastic ring, the fixed company in the elastic ring periphery and undertaking cloth one end in the lifting
It connects, the undertaking cloth other end is fixedly connected with interior guardrail bottom is lifted, and is equipped with heating device, institute in the lifting at the top of guardrail
Stating heating device quantity is N number of, N >=2, and the heating device bottom is equipped with telescopic cylinder, the telescopic cylinder top and spring
One end is fixedly connected, and the spring other end is equipped with except crampon.
Preferably, heating device quantity is 4.
The heating device is made of several heater strips, uses heating method for electric heating.
The telescopic cylinder quantity is identical as heating device quantity.
The elastic ring is the spring that outside is coated with rubber layer.
The claw except crampon is coated with rubber layer.
The invention has the benefit that the present invention is fan blade surface ice sheet removal device, lifting bottom plate and lifting are outer
The surrounded region of guardrail is walked about in guardrail, lifting for staff, elastic ring is directed at fan blade blade tip position, using hanging
Vehicle slings device, makes elastic ring along the slowly friction upwardly of fan blade appearance, and the rubber layer of cladding can avoid scratching blower
The gel coat of blade surface opens heating device in device uphill process, after being heated to the ice sheet on fan blade surface,
Slight thawing occurs for the ice sheet on fan blade surface, when device runs to the root of fan blade, starts telescopic cylinder, makes it most
The crampon that removes of front end is contacted with ice sheet, and ice sheet is isolated into fritter and is fallen off from fan blade surface, the undertaking cloth of bottom will be crushed
Ice cube catch, prevent its fall to the ground accidentally injure staff trash ice is uniformly processed when device drop to ground.This hair
It is bright quickly and effectively to remove the ice sheet on fan blade surface, the feelings for preventing ice sheet from damaging or fractureing to fan blade
Condition avoids economic loss.
Detailed description of the invention
Fig. 1 is main structure chart of the present invention；
Such as figure, lifting bottom plate -1, the outer guardrail -2 of lifting lift interior guardrail -3, elastic ring -4, accept cloth -5, heating device -
6, telescopic cylinder -7, spring -8, remove crampon -9.
Specific embodiment
Shown in reference to the accompanying drawing, invention is further explained: the present invention is the removal of fan blade surface ice sheet
Device, including lifting bottom plate 1, the outer guardrail 2 of lifting, the interior guardrail 3 of lifting, elastic ring 4, undertaking cloth 5, heating device 6, telescopic cylinder
7, spring 8, remove crampon 9, lifting bottom plate 1 generally rectangular-ambulatory-plane lifts to be equipped on the outside of bottom plate 1 and lifts outer guardrail 2, lifting bottom plate 1
Inside, which is equipped with, lifts interior guardrail 3, lifts interior 3 middle position of guardrail and is equipped with elastic ring 4, elastic ring 4 is that outside is coated with rubber layer
Spring, 4 periphery of elastic ring is fixedly connected with 5 one end of cloth is accepted, accept 5 other end of cloth and lift in 3 bottom of guardrail is fixed connects
It connects, lifts and be equipped with heating device 6 at the top of interior guardrail 3,6 quantity of heating device is N number of, N >=2, preferably, the number of heating device 6
Amount is 4, and heating device 6 is made of several heater strips, uses heating method for electric heating, and 6 bottom of heating device, which is equipped with, stretches
Contracting cylinder 7,7 quantity of telescopic cylinder is identical as 6 quantity of heating device, and 7 top of telescopic cylinder is fixedly connected with 8 one end of spring, bullet
