Embodiment Construction

[0028] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0029] Such as figure 1 , figure 2 (a), (b), shown in (c), the nacelle self-unloading device of the present invention comprises two jacking devices 10 with the same structure, separated on the left and right sides of the nacelle car and two jacks for connecting both sides. The connector (movable beam) 7 of the lifting device 10, the front and rear ends of the nacelle base 6 are connected with the two connectors 7 respectively.

[0030] Such as image 3 (a), (b) and Figure 4 (a), (b), (c), shown in (d), the jacking device 10 is made of two jacking units 11, a connecting beam 12 connecting the two jacking units 11, a drive motor 24, a jaw-type electromagnetic The clutch 28, the connecting shaft 27 and the shaft coupling 26 constitute. The jacking unit 11 is composed of an outer cover 23 , an inner cover 22 , a screw jack 17 , a lift support 18 and ...

Abstract

The invention relates to a cabin self-unloading apparatus. A jacking device is composed of two jacking units, a connection beam that helps adapt the two jacking units, a driving motor, a toothed electromagnetic clutch, a connection shaft and a coupling. Each jacking unit is composed of an outer sleeve, an inner sleeve, a screw lift, a lift support and a base; the screw lift, within the inner sleeve, is hinged to the base via the lift support; a screw nut screwed to a spiral screw of the screw lift is hinged to the inner sleeve; a jacking arm is fixed to the lower end of one side of the inner sleeve; a hook portion arranged at the lowermost end of the jacking arm is extended out of the outer sleeve from an opening of the outer sleeve, and a slide rail and a slider are arranged between the inner sleeve and the outer sleeve. Two longitudinal ends of the connection beam are connected with the outer sleeves of the two jacking units; the openings of the outer sleeves face the longitudinal outer side of the jacking device; the driving motor is disposed in the connection beam; output shafts at the two ends of the driving motor are connected with input shaft on the two sides of the screw lift via the couplings, connection shafts and the toothed electromagnetic clutch.

Description

technical field [0001] The invention relates to a mechanical jacking device, in particular to a self-unloading device for a mechanical wind power generator cabin. Background technique [0002] The construction of wind farms is usually carried out by the transportation company using special large-scale transport vehicles to transport the assembly or parts of wind power equipment to the stand, and then the tower, nacelle, hub, blades, etc. are assembled on the prefabricated wind turbine foundation by a large crane . However, due to the high price and small number of large cranes, the price of each shift is not a small amount. Therefore, owners often rent less hoisting equipment to maximize the use of large hoisting equipment. However, for transport vehicles, considering the long distance of transport and many unpredictable events, they are often shipped in advance and enter the site in advance. For the engine room, a large crane of 220t or 260t must be used to load and unloa...
