Abstract
Small portal cranes in the prior art have no vertical walk locking devices, and can be blown by high-altitude wind power. The running mechanisms of the portal cranes are arranged at the lower potion, so the rigidity during walking is small, and the shake is large when a chain hoist hang with an object transversely walks. The positioning of a wind power generation built-in crane disclosed in the invention in the stopping case is more accurate than that of cranes using widely known technologies. The connection stability between a column and a shell is good, so the running of the traveling crane occupies a small space and is safe. The running of the traveling crane does not interfere below workers, so the efficacy is improved. The use of the crane in an aerogenerator is safe. The crane has a good economic benefit. After the shell of a fan is opened, driving gear racks control the walking of the traveling crane, and the traveling crane cannot be blown by wind, so a good positioning locking function is realized under a working or non-working condition.
Description
One, technical field
The built-in hoisting crane of wind-power electricity generation is used for: the maintenance small-scale bridge hoisting crane in wind-power electricity generation casing.
Two, background technology
Existing technology aerogenerator weight-lifting equipment by weights such as the material in shell 0.35 ton, accessory, electrical equipment, cables by longitudinally walking of a kind of small portal crane carrying, the not longitudinal walking latching device of this small portal crane, high-level wind-force can blow small portal crane greatly.Below, when walking, rigidity is little for trestle crane running gear, and ring-chain hoist plays and rocks greatly when object is laterally walked.Installation in position is not easy.Transfer crane walking and below installation personnel are wanted to interfere, and engaged position is large.
Three, summary of the invention
1. the built-in hoisting crane major part of wind-power electricity generation comprises: the built-in hoisting crane of the composition wind-power electricity generation such as column, driving, driven wheel, upper junction plate, motor-driven carrier, ring-chain hoist, bolt pair 1, bolt pair 2, tooth bar, lower connecting plate, bolt pair 3, pressing plate, Blower Housing, track, change speed gear box, electrical controller.
2. the object of the invention is to design the built-in hoisting crane of a kind of wind-power electricity generation.It is characterized in that: lifting altitude is below 130 meters, and vehicular longitudinal direction is walked on built on stilts track, longitudinally walking is by the combination of driving gear wheel and rack, driven wheel is walked before and after rotating and driving vehicular longitudinal direction, and the drg of driving is that length is closed state, just brake after power-off, after brake, driven wheel can not rotate, and driving can not be longitudinal, front and back walking, wind blows driving motionless, the load of wind to driving when that is to say driving operation and stopping, driving can be walked, can be accurately in place in the situation that stopping.Column and housing connective stability are good, the face walking in orbit of driving a vehicle., safety little with space are bored in driving in the above operation.The staff who gets along well below when driving operation interferes, and improves effect.The welding of lower connecting plate and column, 4 are connected with Blower Housing with bolt pair 3 with above column, when column installation with instrument levelling, look for vertically, parallel dimension limit is at positive and negative 2 millimeters.The certain distance in the symmetrical interval of column in wind turbine equipment not interference apparatus install, column has the position of installation, installation and maintenance personnel can pass through, column composition two rows install.Lower connecting plate on column is connected with Blower Housing bolt hole through the hole of lower connecting plate with bolt pair 3.Upper junction plate and column are welded on column upper end, and column is linked together.Bolt pair 1 tooth bar is connected with upper junction plate screw through rack bore.Tooth bar is installed at grade, and plane tolerance is bolt pair 2 for 0.6mm, passes pressing plate, and pressing plate one end contacts one end and contacts with upper junction plate with track, and bolt pair 2 is connected with upper junction plate screw, and track is pressed in the upper plane of upper junction plate.The horizontal tolerance 1mm of track installation requirement, parallel tolerance 2mm.With crane traveling crane get up install in orbit.Driving gear wheel and rack in driving combines.Motor-driven carrier is arranged on the single-beam of driving, and ring-chain hoist is arranged on motor-driven carrier, and driven wheel is arranged on the output shaft of change speed gear box.Electrical controller is arranged on motor-driven carrier.After driving, motor-driven carrier, ring-chain hoist install, will carry out commissioning test, vehicular longitudinal direction running is wanted steadily, nothing sound of movement extremely, and motor-driven carrier laterally running is wanted steady, the abnormal sound of movement of nothing.Ring-chain hoist will carry out zero load, rated load, 25% overloading experiment before using.Driving, motor-driven carrier will be with the load on ring-chain hoist in length and breadth to walking.Whether the steel structure that unloads the built-in hoisting crane of load check wind-power electricity generation has permanent deformation, and weld seam has flawless, and bolt pair has non-loosening, in the situation that the built-in hoisting crane of wind-power electricity generation is intact.Carry out record of survey, after security staff checks, could use.
3. the present invention is compared with known technology, vehicular longitudinal direction is walked on built on stilts track, longitudinally walking is by the combination of driving gear wheel and rack, driven wheel is walked before and after rotating and driving vehicular longitudinal direction, the drg of driving is that length is closed state, and just brake after power-off, after brake, driven wheel can not rotate, can be accurately in place in the situation that stopping.Column and housing connective stability are good, and, safety little with space are bored in driving in the above operation.The staff who gets along well below when driving operation interferes, and improves effect.Be used on aerogenerator, use safety.There is better economic benefit.After Blower Housing is opened, have the walking of driven wheel tooth bar control driving, the motionless driving of wind has good positioning and locking function in the time working and do not work.
Four, accompanying drawing explanation
