The guide rail bracket 10 of connection, the vertical guide rail 12 being arranged on guide rail bracket 10, by driving means (not shown) drives edge vertical guide rail
The slide block 14 of 12 lengthwises for moving up and down, the bottom of slide block 14 is fixedly installed a manned platform 16.Manned platform 16 is opened for one
The case structure put, upper surface is used to place driving means, its simple structure, lighter in weight in the people that stands, case, and is easy to work
Personnel can at any time observe wind-power tower；The control driving means of guidance panel 18 being arranged on slide block 14 are reached by, so as to
Lifting is shut down, to carry out overhauling maintenance etc. to wind-power tower.The buttons such as rising, decline, jerk are set on guidance panel 18.
The guardrail 20 being connected with manned platform 16 is provided with the slide block 14 of the top of manned platform 16, driving means drive and carry
People's platform 16 and guardrail 20 are together moved up and down along vertical guide rail 12.The both sides of slide block 14 are provided with friction lever 22, guardrail 20
It is the loop configuration of a side opening, two sides of guardrail 20 are slidably fixed on friction lever 22, and the surface of friction lever 22 has
The larger top layer of one frictional force, guardrail 20 need to overcome frictional force to slide up and down along friction lever 22 under outer power push-and-pull action, make shield
Relative altitude between hurdle 20 and manned platform 16 is apart from adjustable；When guardrail 20 is acted on without external force, it is between friction lever 22
Frictional force can overcome gravity suffered by it, keep geo-stationary between guardrail 20 and friction lever 22 fricton-tight.As work people
When member enters manned platform 16, guardrail 20 can be pushed to top and enter manned platform 16, and need not bend over to enter；As work people
When member stands on manned platform 16, then guardrail 20 is drawn down from above, the height of guardrail 20 can be adjusted according to oneself height, made
Guardrail 20 is located at around above the waist, is easy to protect staff itself, and guardrail 20 adjusts simple, convenient, fast.
The block of the extreme lower position that a restriction guardrail 20 glides relative to manned platform 16 is also set up between manned platform 16 and guardrail 20
（It is not shown）, during preventing guardrail 20 because of unexpected unlimited downslide protective action is lost.
In the present embodiment, driving means are hoist engine 38, and the main body of hoist engine 38 is arranged in the casing of manned platform 16.Volume
Raise the traction drive that the steel wire rope 24 that machine 38 is connected by folding and unfolding with manned platform 16 is realized to manned platform 16.Manned platform 16
On be also associated with safety rope 26, steel wire rope 24 fracture etc. fortuitous event occur when, prevent manned platform 16 from falling.Steel wire rope 24
With the top that one end of safety rope 26 is both secured to tower, to guarantee the lifting height of manned platform 16.
