Background technology
Horizontal axis wind-driven generator, when adopting three cylinder wheel hubs to be connected with blade, three of wheel hubs and sharf are 93 ° to the angle of the coaxial face of cylinder and slow-speed shaft.For making things convenient for the blower fan on-site maintenance, climbing ladder apparatus need be installed in wheel hub.Climbing ladder apparatus of the present utility model comprises: three supports 2 that are connected with 1 three inwalls of wheel hub, with three described supports 2 by fixing three the cat ladder 3(of connector referring to Fig. 1).
The climbing ladder apparatus of prior art is two bottoms at each cat ladder, is the inclined-plane steel plate of 3 ° of angles and angle steel welding with the bottom surface, realizes in the wheel hub (see figure 7) that is connected between three supports and the cat ladder.This structure, not only the making of connector need be processed the inclined-plane of steel plate, and welding angle steel and inclined-plane steel plate are wasted time and energy, and the site assembly difficulty, and simultaneously, the device overall dimensions is bigger, can not effectively utilize the space.
The utility model content
The purpose of this utility model is to overcome the shortcoming of prior art, and the climbing ladder apparatus in a kind of wind generator unit wheel hub is provided, and solves existing climbing ladder apparatus complex manufacturing technology, and difficulty is installed, and overall dimensions is big, the technical problem of Heavy Weight.
The utility model is achieved through the following technical solutions:
Climbing ladder apparatus in a kind of wind generator unit wheel hub comprises: three supports that are connected with three inwalls of wheel hub, three cat ladders fixing by connector with three described supports; Each described cat ladder is made of two longitudinal rods and several transverse bars, and two described longitudinal rods are welded as a whole for 120 ° with angle by long rectangular tube and short rectangular tube respectively, and described transverse bar is square tube; It is characterized in that: and the connector between described support and the described cat ladder, comprise: 93 ° of bending steel plates, 87 ° of bending steel plates, and steel plate, weld described steel plate respectively in described long rectangular tube and two bottoms of short rectangular tube, the one side of described 93 ° of bending steel plates is connected with described steel plate on the short rectangular tube by the described long rectangular tube of bolt and main shaft side, and described 93 ° of bending steel plate another sides are by being bolted on the described support; The one side of described 87 ° of bending steel plates is connected with described steel plate on the short rectangular tube by the described long rectangular tube of bolt and wind wheel side, and the another side of described 87 ° of bending steel plates is by being bolted on the described support.
When described 93 ° of bending steel plates and 87 ° of bending steel plates are installed, be placed on the inboard of two described longitudinal rods.
The utility model compared with prior art because the connector between support and the cat ladder, has adopted the bending steel plate of two kinds 93 ° and 87 °, and use bolted structure, when not only having saved machine and Welder, and made things convenient for installation, simultaneously, reduce the gross weight of device, reduced cost.The utility model is used for adopting three horizontal axis wind-driven generators that the cylinder wheel hub is connected with blade, has the processing of being easy to, and convenient on-the-spot the installation saved man-hour, the advantage that cost is low.
