Between top holding groove and bottom holding groove, also be provided with at least one middle part holding groove.
Described support slot group is provided with at least one support slot, and the support slot height is between adjacent two holding grooves, and is and suitable with strut lengths.
The elevating method of wind-driven generator tower frame of the present invention is: elevate a turnable ladder may further comprise the steps:
1), lowering or hoisting gear is hinged on the pylon engaging lug, the motion end of lowering or hoisting gear is positioned in the bottom holding groove of bearing frame, and the action of operation lowering or hoisting gear to the design runlength height, stops;
2), the lower end that will be hinged on the pole on the pylon, be positioned in the support slot, the operation lowering or hoisting gear shortens stroke, the motion end of lowering or hoisting gear is withdrawed from from the holding groove of bottom, at this moment, the mediate pylon of state of pole support;
3), the motion end of lowering or hoisting gear is inserted in the adjacent holding groove, the action of operation lowering or hoisting gear to the design runlength height, when pylon is upright, is fixedly connected pylon with base, and elevate a turnable ladder finishes;
Falling down step is reversed by the elevate a turnable ladder step.
The present invention changed the pattern that hoist cylinder in the past fixedly installs, adopted can the mobile position lowering or hoisting gear and support, through lowering or hoisting gear elongation stage by stage, realized the rise of large-scale pylon.Lowering or hoisting gear of the present invention can adopt less oil hydraulic cylinder, Electrohydraulic push rod, mechanic jacks etc., is convenient for carrying, and is easy and simple to handle, reduced installation cost.In lift work, safe, labor intensity is little.

Embodiment
Wind-driven generator tower frame of the present invention is as shown in Figure 1; Comprise and be fixed in ground base 1, the pylon 4 hinged with base 1; Pylon 4 is hinged through hinge 2 and base 1, and pylon 4 can be done the motion of level to erectility with respect to base 1 through lowering or hoisting gear 7, and base 1 is provided with bearing frame 8 towards a side of pylon 4; Pylon 4 is hinged with pole 6 near the articulating point place through pole hinge pin 5, on the pylon below the pole 64, also is provided with the engaging lug 3 that is used to be hinged lowering or hoisting gear 7; The lower end of corresponding pole 6 is provided with support slot group 60 on the bearing frame 8, and the motion end of corresponding lowering or hoisting gear 7 is provided with holding groove group 70.
As shown in Figure 2; Holding groove group 70 on the base 1 one side bearing frames 8 comprises subaerial bottom holding groove 701 and the top holding groove 703 that is positioned at bearing frame 8 tops, the range height of the distance≤lowering or hoisting gear 7 between the engaging lug 3 on the pylon 4 of top holding groove 703 and erectility; The range height of the distance≤lowering or hoisting gear 7 between the engaging lug 3 on the pylon 4 of bottom holding groove 701 and level.Between top holding groove 703 and bottom holding groove 701, also be provided with at least one middle part holding groove 702.Support slot group 60 on the base 1 one side bearing frames 8 is provided with support slot 1, support slot 2 602, and being provided with highly of support slot 1, support slot 2 602 is: between adjacent two holding grooves, and suitable with the length of pole 6.
The elevating method of wind-driven generator tower frame of the present invention is shown in Fig. 3～8, and the elevate a turnable ladder operation may further comprise the steps:
1), as shown in Figure 3, this moment, pylon 4 levels were the original state of elevate a turnable ladder operation, oil cylinder 71 were hinged on the engaging lug 3 of pylon 4, the motion end of oil cylinder 71 is positioned in the bottom holding groove 701 of bearing frame, pole 6 is a free state; Operating cyloinder 71 actions to the design runlength height, stop;
2), as shown in Figure 4, start the oil station and be oil cylinder 71 oilings, oil cylinder 71 begins elongation, pylon 4 is raised.When support slot one 601 places are dropped in the lower end that oil cylinder 71 is elongated to pole 6, a small amount of oil return in process oil station, the lower end of pole 6 can be dropped on one 601 li of support slots automatically; As can not get into smoothly, then with the lower end of pole 6, being positioned in the support slot 1, operating cyloinder 71 shortens strokes, and the motion end of oil cylinder 71 is withdrawed from from bottom holding groove 701, and at this moment, pole 6 is supported the pylon 4 of the state that mediates;
3), as shown in Figure 5; Continuing the process oil station shortens oil cylinder 71; Because oil cylinder 71 is connected on the pylon 4, so breaking away from, its movable end can break away from bottom holding groove 701, when oil cylinder 71 shortens to the position of middle part holding groove 702 by the time; The process oil station is oil cylinder 71 oilings, is that oil cylinder 71 movable end automatic or manuals fall into middle part holding groove 702.(because pole 6 is being supported pylon 4 in this process, so oil cylinder 71 off-load smoothly, shortening)
Then, as shown in Figure 6, the process oil station is oil cylinder 71 oilings, and oil cylinder 71 continues elongation, and pylon 4 is raised.When oil cylinder 71 is elongated to 6 a bar lower end correspondence at support slot 2 602 places, a small amount of oil return in process oil station, the lower end of pole 6 can be dropped on 2 602 li of support slots automatically.
Then, as shown in Figure 7, continue the process oil station oil cylinder 71 is shortened, with the movable end entering top holding groove 703 of oil cylinder 71, operating cyloinder 71 elongations, upright until pylon 4, as shown in Figure 8, pylon 4 is fixedly connected with base 1, the elevate a turnable ladder operation finishes.
The step of falling down pylon 4 is reversed by the elevate a turnable ladder step.
