Abstract
The utility model discloses a special lifting machine for wind power. The special lifting machine comprises an underframe connected with a self-lifting device, wherein the underframe is provided with a balancing device, the other end of the balancing device is articulated to a bottom beam, the bottom beam is articulated to a gantry, and a lifting mechanism is arranged at the top of the gantry. With the adoption of the technical scheme, the special lifting machine has the advantages that when the special lifting machine is used, the underframe is fixed below a unit installation platform, the self height of a fan tower drum is utilized to carry out lifting operation, and therefore, compared with other ground (overwater) cranes, the special lifting machine is free from restriction of lifting height; and meanwhile, because bearing strength is not needed on the ground (water surface), the special lifting machine is not restricted by the ground (water surface) environment and basically keeps an original environment state, so that damages to the environment are relieved, and the applicability, the reliability and the safety of installation and maintenance of a wind power unit are greatly improved.
Description
Technical field
The utility model relates to a kind of lifting device, specifically relates to a kind of wind power generating set self-lifting hoister specialized equipment based on the blower fan main frame.
Background technology
The existing wind-powered electricity generation lifting unit assembling of ship machinery patterns that adopt based on the ground or the water surface adopt large automobile crane, crawler crane and marine crane barge to accomplish more.Along with the increasing of the continuous increase of wind-powered electricity generation unit weight, blower fan pylon, topography and geomorphology and investor that the fabricating yard is special require to accelerate the requirement that installation rate obtains gain on investments as far as possible; This just requires increasing hanging device, makes equipment investment significantly increase; Along with the continuous operation of equipment, the maintenance of blower fan parts is changed unavoidable, traditional unit assembling of ship machinery detachment mode and is required to accomplish with same large-scale hanging device on the other hand, and expense is high, the cycle is long, poor stability.Therefore, existing lifting mode and hanging device be incompatibility wind-powered electricity generation lifting demand more and more, and the novel hanging device of exploitation adaptation wind-powered electricity generation development tendency is imperative, and important practical sense and essentiality are arranged.
Summary of the invention
The purpose of the utility model provides the special-purpose loop wheel machine of wind-powered electricity generation that a kind of cost is low, safety is good.
For realizing above-mentioned purpose, the utility model adopts following technical scheme:
The utility model comprises the underframe that is connected with from rising device, and balancing device is set on the underframe, the hinged bottom girder of the other end of balancing device, and hinged door frame on the bottom girder, the door frame top is provided with lifting mechanism.
The side of said door frame is provided with luffing device, the hinged door frame of luffing device one end, the hinged bottom girder of the other end.
Described luffing device, balancing device are hydraulic actuating cylinder.
The below of said door frame is provided with lock shaft device.
Adopt the utility model of technique scheme, have the following advantages:
When (1) using, the underframe in the utility model is fixed on unit erecting stage below, utilizes the blower fan tower barrel oneself height to carry out lifting operation, therefore compare, broken away from the restriction that receives the crane hoisting height with other ground (waterborne) hoisting crane; Because the utility model not be used in ground (water surface) load is installed simultaneously; Can not receive the restriction of ground (water surface) environment; Basically keep former ambient condition, reduced, also improved applicability, reliability, the safety of installing and safeguard the wind-powered electricity generation unit greatly environment damage.
(2) adopting door frame to add luffing device makes this equipment availability scope cover whole blower fan; The scope of work all standing, degree of utilization is high, does not stay the dead angle; Can lift the wind impeller hub, change blade; Be specially adapted to modular lifting wind-powered electricity generation unit main parts size gear case, generator set, air-conditioning cooling mechanism etc., the alerting ability of on-the-spot service is strong, is used for the wind field installation and then can effectively reduces delivery period.
(3) be provided with installing/dismounting and use self-hoisting unit of TQ 60/80, can realize going up and down to install voluntarily, avoid the use of large-scale auxiliary erecting equipment, operating costs is low.
(4) because this device has adopted no body of the tower structure; Do not have complicated ground walking device, thereby simple in structure, make, cost of installation is low; Be convenient to the use of repeatedly cutting to; Be used for the wind energy turbine set maintenance and can avoid or reduce the use goliath, efficient is high, can effectively reduce wind energy turbine set production maintenance cost and time.

The specific embodiment
Like Fig. 1, Fig. 2, shown in Figure 3, the utility model comprises the underframe 8 that is connected with from rising device 6, and balancing device 4 is set on the underframe 8, the hinged bottom girder 5 of the other end of balancing device 4, and hinged door frame 2 on the bottom girder 5, door frame 2 tops are provided with lifting mechanism 1.
The side of door frame 2 is provided with luffing device 3, the hinged door frame 2 of luffing device 3 one ends, and the hinged bottom girder 5 of the other end, in Fig. 2, door frame 2 is in the left side and is preceding end position, and door frame 2 is in the right side and is the back end position.And the below of door frame 2 is provided with lock shaft device 7.
Above-mentioned luffing device 3, balancing device 4 are hydraulic actuating cylinder, and hydraulic actuating cylinder all is connected with hydraulic efficiency pressure system.
The method of application of the utility model is: as shown in Figure 3 before the installation, earlier underframe 8 is placed on the ground, and door frame 2 is supported in ground temporarily, and adjustment balancing device 4 oil cylinders make door frame 2 levels, and complete machine is in minimum constructive height, is convenient to transportation and moves.During installation; The steel rope that will rise device 6 is certainly walked around the pulley that is fixed on the blower fan frame; Drive from rising device 6 elevators, the equipment self of slinging is extremely highly approaching with blower fan main frame lower platform, adjustment balancing device 4; Through guide piece the frame in underframe 8 and the blower fan main frame is installed together with bearing pin, is locked.Continue adjustment balancing device 4, pull-up door frame 2 is fallen in the axle bed on the underframe 8 down hinge of door frame 2, through lock shaft device 7 door frame 2 lockings is reached equipment working state.
During equipment work; Door frame 2 is combined into diagram 2 states with underframe 8 through hinge with bottom girder 5 and luffing device 3; Need to install the perhaps blower fan components module of dismounting through jack up unit 1 lifting that is contained in door frame 2 tops, thereby article moves up and down between realization ground and the blower fan height; Lifted by crane the height of needs when article after; Through luffing device 3 telescopic oil cylinders drive door frame 2 around and bottom girder 5 between hinge rotate; Drive institute's article that hang and in horizontal extent, move, thereby realize the blower fan components module that is hung is in place in the correct position dismounting.
Operation finishes, and in the time of need specialized equipment being pulled down, opens lock shaft device 7; Adjustment balancing device 4 oil cylinders are set level door frame 2, return to diagram 3 states, slowly adjust balancing device 4 oil cylinders and cooperate to rise device 6 winch action certainly; Pull down underframe 8 and the interior frame bearing pin of blower fan main frame successively, reversing sense drives from rising device 6 elevators, and special-purpose loop wheel machine is drop to ground from the high-altitude; Put down steel rope from blower fan main frame pulley, pack up.Be used to complete, transition continues to use next time.
