Fig. 2 is the back view of windmill service elevator one preferred embodiment of the present invention;
Fig. 3 is the structural representation of the friction winding mechanism of windmill service elevator of the present invention.
Wherein accompanying drawing is designated: 1, terraced rail; 2, car; 3, driving steel wire rope; 4, roller guide assembly; 5, friction winding motor; 6, steel rope connecting gear; 7, control housing; 8, velocity limiter; 9, safety tongs; 10, braking rail; 11 energy dispersers.
The specific embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present invention is set forth in detail, thereby protection scope of the present invention is made more explicit defining so that advantage of the present invention and characteristic can be easier to it will be appreciated by those skilled in the art that.
Windmill service elevator of the present invention is directed against the special construction of wind tower and highly innovates, and is different from conventional lift.One of difference of windmill service elevator of the present invention and conventional lift is: type of drive is different.Concrete, windmill service elevator of the present invention is through the operation on the driving steel wire rope of friction winding driven by motor car.Another some difference part is that the particularity of wind tower has determined windmill service elevator of the present invention to install and to use in the open, does not have hoistway.At innovative point simultaneously, windmill service elevator of the present invention has also kept the structure and the safety system of conventional lift.Specifically describe as follows.
See also Fig. 1 and Fig. 2.Windmill service elevator of the present invention comprises terraced rail 1, the car 2 along terraced rail 1 operation, driving steel wire rope 3, friction drive hoist system, control system and safety system, and said friction drive hoist system drives said car 2 along terraced rail 1 operation.
Car 2 comprises envelope, framework and roller guide assembly 4.Wherein, framework is provided with along terraced rail 1, and roller guide assembly 4 connects this framework and envelope.During normal the use, car 2 moves along terraced rail 1 through roller guide assembly 4.
See also Fig. 3, the friction drive hoist system comprises friction winding motor 5 and rope grip mechanism.The friction winding system comes clamping driving steel wire rope 3 through tribology principle, moves up or down thereby drive car 2.Specifically; This friction winding system promotes through 6 pairs of driving steel wire ropes 3 of the steel rope connecting gear on the friction winding motor 5; This driving steel wire rope 3 is connected with car 2, thereby it is mobile on terraced rail 1 through roller guide assembly 4 to drive car 2, the operation up or down of realization car 2.
Usually the friction drive hoist system is fixed in the top of car 2, also can be installed on other suitable positions.
Control system comprises the control housing 7 and the electric control system of control friction winding motor 5 operations.Control housing 7 is fixed on car 2 tops usually, is used to control the operation of friction winding motor 5, also can be installed in other positions.
Electric control system comprises that this cable continues to the power devices on the car 2 with the car 2 common supply cables of falling that rise.
When unexpected stall or disconnected rope appearred in the windmill service elevator, safety system worked.Safety system comprises velocity limiter 8, safety tongs 9 and energy disperser 11.When speed surpasses the speed limit of velocity limiter 8 of hypervelocity monitoring device, velocity limiter 8 actions, 9 actions of pulling safety tongs are stuck in car 2 on the braking rail 10, make car 2 stops.If windmill service elevator stall whereabouts but all surpass the action speed limit of velocity limiter 8 in the dropping process, when perhaps velocity limiter 8 was with safety tongs 9 system downs, the energy disperser 11 that is positioned at terraced rail 1 lowest part played a protective role, and slowed down the injury that produces at the bottom of car 2 crouchings.
If the windmill service elevator stops in midair, can't fall, trapped personnel also can swash from terraced rail 1, reaches the purpose of saving oneself.
In sum, windmill service elevator of the present invention adopts the friction winding motor to reach the purpose that the pulling car moves up and down through the lifting to the driving steel wire rope.This windmill service elevator compact conformation, safe and reliable both can use on the wind tower of wind-power electricity generation, also can use on the high tower of similar structures as safeguarding accessory equipment, had played positive effect to improving maintenance work efficient.
The above; It only is the specific embodiment of the present invention; But protection scope of the present invention is not limited thereto; Any those of ordinary skill in the art are in the technical scope that the present invention disclosed; Variation or the replacement that can expect without creative work all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claims were limited.
