Abstract
The utility model provides a general type hoisting accessory of wind -powered electricity generation gear box planetary gear, is including lifting by crane support, slider, base, the crossbeam both sides of lifting by crane the support be equipped with spacing bolt, lift by crane the base of support on the trompil be connected with connecting bolt, connecting bolt connects base and the planetary gear who lifts by crane the support, the slider be located on the crossbeam that lifts by crane the support between the two spacing bolts, the slider top is connected with the lug, is equipped with fastening bolt in the middle of the slider. The utility model discloses the commonality is strong, and application scope is wide, can link together not unidimensional planetary gear through the model specification that changes connecting bolt, is applicable to different dimensions's the lifting by crane and the leveling of NGW gear box planetary gear. The operation requirement had both been satisfied in the use of spacing bolt, had also reduced the manufacturing cost of device.
Description
Technical field
This utility model belongs to hanging apparatus technical field, particularly relates to a kind of universal boom hoisting of wind turbine gearbox planetary gear.
Background technology
Gear-box in wind power generating set is an important mechanical part, and its main function is to be passed to electromotor and make it obtain corresponding rotating speed by wind wheel produced power under wind-force effect. Most commonly seen with fixing parallel-axes gears transmission and Planetary Gear Transmission in wind-powered electricity generation field horizontal axis wind-driven generator group, the wind turbine gearbox of NGW structure is typically mounted in the small space of tower top, and the planetary gear within gear-box is once break down, repair difficulty very big, along with wind power generating set keeps the large-scale development, the wind turbine gearbox planetary gear of the NGW structure for breaking down, disassembling, assembling and replacing must be carried out, in order to enable more quickly the planetary gear of different structure to be installed and leveling, it is necessary for designing a kind of planetary gear boom hoisting.
Summary of the invention
This utility model is for achieving the above object, it is provided that a kind of highly versatile, wide accommodation, it is adaptable to the lifting of the NGW gearbox planetary gear of different size specification and levelling device.
Technical solution adopted in the utility model is:
A kind of universal boom hoisting of wind turbine gearbox planetary gear, including hoisting bracket, slide block, base, the crossbeam both sides of described hoisting bracket are provided with caging bolt, and on the base of hoisting bracket, perforate is connected to connecting bolt, and connecting bolt connects base and the planetary gear of hoisting bracket; Described slide block is on the crossbeam of hoisting bracket between two caging bolts, and slider top is connected to hanger, is provided with fastening bolt in the middle of slide block.
The diameter of described caging bolt, fastening bolt and hanger is 16mm.
The beneficial effects of the utility model: this device highly versatile, applied widely, various sizes of planetary gear can be linked together by changing the model specification of connecting bolt, it is adaptable to the lifting of the NGW gearbox planetary gear of different size specification and leveling;The use of caging bolt, had both met instructions for use, also reduced the manufacturing cost of device.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein: 1-hanger; 2-slide block; 3-fastens bolt; 4-left limit bolt; 5-right limit bolt; 6-hoisting bracket; 7-connecting bolt; 8-planetary gear; 9-crossbeam; 10-base.
Detailed description of the invention
A kind of universal boom hoisting of wind turbine gearbox planetary gear, including hoisting bracket 6, slide block 2, base 10, crossbeam 9 both sides of described hoisting bracket 6 are provided with left limit bolt 4 and right limit bolt 5, on the base 10 of hoisting bracket 6, perforate is connected to connecting bolt 7, and connecting bolt 7 connects base 10 and the planetary gear 8 of hoisting bracket 6; Described slide block 2 is between the upper left caging bolt 4 of crossbeam 9 and the right limit bolt 5 of hoisting bracket 6, and slide block 2 top is connected to hanger 1, is provided with fastening bolt 3 in the middle of slide block 2.
In the specific implementation, hanger 1 is connected this device with overhead traveling crane, and connecting bolt 7 is connected with planetary gear 8 to be lifted, realizes the single-point lifting of planetary gear 8 with this. Slide block 2 can slide on the crossbeam 9 of hoisting bracket 6, and sliding scale is the distance between caging bolt 4 and caging bolt 5. When slide block 2 slides into correct position (by planetary gear 8 center of gravity), the planetary gear 8 of overhead traveling crane lifting keeps level, tightened by fastening bolt 3 and slide block 2 can be fixed on correct position (by planetary gear 8 center of gravity), it is prevented that slide block 2 continues to slide on the crossbeam 9 of hoisting bracket 6 in lifting and transportation. Lifting by crane and leveling by the arrangement achieves the single-point of planetary gear 8, facilitating operator and planetary gear 8 from dismounting planet carrier and is assembled on planet carrier by gearbox planetary gear.
