Description

A kind of special maintenance crane of Portable wind-driven generator cabin
Technical field
This utility model belongs to wind-driven generator service technique field, more particularly, to a kind of Portable wind-driven generator machine The special maintenance crane in cabin.
Background technology
Modern asynchronous double-fed wind power generator, cabin are up to 80m, and in cabin, electromotor, gear-box, driftage driving etc. are each is System parts are all heavier, and generally weigh more than 100kg.Once aircraft compartment interiors break down, as which is in height in the air, and machine Cabin bulk is narrow and small, and various pipelines, cable gather wherein, and personnel are difficult to keep a foothold.During maintenance, heavy parts are dismantled, are removed Fortune problem, becoming affects the greatest difficulty of service work, and the main unstable factor for affecting maintenance person's personal safety.
Traditional cabin maintenance mode, if changing heavy parts, it is necessary to made a concerted effort using many people, with prizing, push away, remove, lift Simple manpower mode, due to cabin space compact conformation, personnel are difficult to keep a foothold, and slightly mishap will be broken and parts or even be made Into personal injury, take a lot of work laborious and dangerous.Maintenance duration prolongation is ultimately resulted in, the cost of overhaul is used and production loss is high.Therefore It is badly in need of one kind to can solve the problem that in the narrow cabin in wind turbine high-altitude, the engine rooms of wind power generators of the problem that weight safty hoisting is carried is special With maintenance crane.
Utility model content
In order to solve the above problems, this utility model provides a kind of special maintenance of Portable wind-driven generator cabin and hangs Car, this utility model can effectively solve the problem that in the narrow cabin in wind turbine high-altitude, the problem that weight safty hoisting is carried.
Technical solution of the present utility model is:A kind of special maintenance crane of Portable wind-driven generator cabin, including Bearing, pivot pin, column and swing arm, are connected by pivot pin between the column and swing arm, crane can be disintegrated by plugging pivot pin, Dispersion deadweight and overall dimension, the column are fixed on the bearing, and the bearing, column, three part of swing arm adopt split Transport, field-installed mounting means, can pass through the slypes such as cabin hole for hoist, improve portability.
It is further preferred that triangle reinforcement is provided with the inside of the swing arm.
It is further preferred that the special crane outward appearance of overhauling of the Portable wind-driven generator cabin is in " 7 " font.
This maintenance crane, can jail by hole for hoist screw pivot pin by the use of fan engine room base hole for hoist as bearing fixing point Admittedly fixed engine room foundation and bearing, this maintenance crane can be installed to the multiple positions of cabin, chain block is coordinated to use, it is actual to survey Institute within the 180kg such as examination, yaw motor of can slinging, box bearing, liquid braking device, braking deep bid, wind turbine shaft coupling There is weight.
This utility model is had the advantages that compared with the prior art:
(1)The special maintenance crane of this blower fan, solves in the narrow cabin in wind turbine high-altitude, and what weight safty hoisting was carried asks Topic.Maintainer's quantity can be greatly reduced using this jenny;Reduce personnel labor intensity;Improve safety inspection coefficient.
(2)This special mobile crane can lift yaw motor, box bearing, brake, braking deep bid, wind turbine connection Axle device etc., nearly all common heavy parts, greatly reduces maintainer's quantity;Reduce personnel labor intensity;Improve peace Full inspection repaiies coefficient.
Description of the drawings
Fig. 1 is a kind of special maintenance crane overall structure diagram of Portable wind-driven generator cabin of this utility model;
In figure:1 is swing arm, and 2 is column, and 3 is bearing, and 4 is pivot pin, and 5 is triangle reinforcement, and 6 is engine room foundation, and 7 are Hole for hoist screw pivot pin.
Specific embodiment
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out Clearly and completely describe.
Embodiment:Such as Fig. 1, a kind of special maintenance crane of Portable wind-driven generator cabin, including it is bearing 3, pivot pin 4, vertical Post 2 and swing arm 1, are connected by pivot pin 4 between the column 2 and swing arm 1, crane can be disintegrated by plugging pivot pin 4, and dispersion is certainly Weight and overall dimension, the column 2 are fixed on the bearing 3, and the bearing 3, column 2,1 three part of swing arm are transported using split Defeated, field-installed mounting means, can pass through the slypes such as cabin hole for hoist, improve portability.
It is further preferred that triangle reinforcement 5 is provided with the inside of the swing arm 1.
It is further preferred that the special crane outward appearance of overhauling of the Portable wind-driven generator cabin is in " 7 " font.
This maintenance crane by the use of 6 hole for hoist of fan engine room base as 3 fixing point of bearing, by hole for hoist screw pivot pin 7 Engine room foundation 6 and bearing 3 can be fixedly secured, this maintenance crane can be installed to the multiple positions of cabin, coordinate chain block to use, The 180kg such as actual test, yaw motor of can slinging, box bearing, liquid braking device, braking deep bid, wind turbine shaft coupling Within all weights.
This utility model is had the advantages that compared with the prior art:
(1)The special maintenance crane of this blower fan, solves in the narrow cabin in wind turbine high-altitude, and what weight safty hoisting was carried asks Topic.Maintainer's quantity can be greatly reduced using this jenny;Reduce personnel labor intensity;Improve safety inspection coefficient.
(2)This special mobile crane can lift yaw motor, box bearing, brake, braking deep bid, wind turbine connection Axle device etc., nearly all common heavy parts, greatly reduces maintainer's quantity;Reduce personnel labor intensity;Improve peace Full inspection repaiies coefficient.
Although the above-mentioned accompanying drawing that combines is described to specific embodiment of the present utility model, not to utility model The restriction of protection domain, one of ordinary skill in the art should be understood that on the basis of the technical solution of the utility model, this area Various modifications or deform still in protection domain of the present utility model that technical staff is made by need not paying creative work It is interior.
