Description

The special-purpose detachable lifting-point device of double-feedback aerogenerator group base
Technical field
The utility model relates to a kind of detachable lifting-point device, is specifically related to the special-purpose detachable lifting-point device of a kind of double-feedback aerogenerator group.
Background technology
At present, mostly wind power generating set after engine room base is weldment, and mostly the hanger on the base is welded type, promptly is welded as a whole with base.Though convenient like this lifting has tangible deficiency.After blower fan was installed end, hanger no longer worked, and because the position basic fixed of hanger on the one hand, has influenced the opening angle of master control cabinet door, caused electric maintenance inconvenience relatively.On the other hand, caused inconvenient walking to a certain extent.
The utility model content
The utility model technical matters to be solved is the deficiency to above-mentioned prior art; Provide a kind of double-feedback aerogenerator group after engine room base special-purpose detachable lifting-point device; It is characterized in that: comprise hanger and bolt, said detachable hanger is installed on the base top panel of double-feedback aerogenerator group after engine room through bolt.Described hanger is detachable; Detachable hanger can be dismantled with high strength bolt through the dismounting steel structure and remove after the installation; Thereby master control cabinet door can be opened bigger angle, and convenient electric service personnel is safeguarded, has also made things convenient for the walking in the cabin to a certain extent.In addition, detachable hanger can be transported to ground through lifting machine in the cabin, can use in all the other base cocycles again, has saved material, has reduced productive costs.
As the further improved technical scheme of the utility model, also comprise reinforced plate, said reinforced plate is fixedly mounted on the base top panel of double-feedback aerogenerator group after engine room.Through reinforced plate is set, make the base top panel can bear enough big bearing capacity.
As the further improved technical scheme of the utility model, said reinforced plate is welded on the lower surface of the base top panel of double-feedback aerogenerator group after engine room.Through the reinforcement of weld plate, reinforced plate is fully captiveed joint, with the base top panel so that the base top panel can bear enough big bearing capacity.
As the further improved technical scheme of the utility model, said hanger is provided with the screw suitable with bolt.
As the further improved technical scheme of the utility model, the panel and the reinforced plate of said double-feedback aerogenerator group after engine room base are provided with the screw suitable with bolt.Bolt passes the screw on base top panel and the reinforced plate, and and screw be between screw thread fit, can hanger be fixed on the base top panel on the one hand, on the other hand,, realized the detachable function of hanger through demounting bolt.
As the further improved technical scheme of the utility model, said bolt is that steel structure is used high strength bolt.
The utility model adopts detachable hanger, and hanger is detachably removed after the installation; Said base top panel makes the base top panel can bear enough big bearing capacity through the reinforcement of weld plate; Described base top panel and reinforced plate have been provided with screw, and hanger and base top panel and reinforced plate pass through bolted connection.Said bolt is that steel structure is used high strength bolt, and utilizes reinforcing sheet material that the base top panel of double-feedback aerogenerator group is reinforced, and connects hanger and engine room foundation through steel structure with high strength bolt.Earlier hanger is contained on the after engine room base before the lifting, treat to take off bolt after lifting is accomplished, and hanger is removed, thereby master control cabinet door can be opened bigger angle, convenient electric service personnel is safeguarded, has also made things convenient for the walking in the cabin to a certain extent.In addition, hanger can be transported to ground through lifting machine in the cabin, can use in all the other base cocycles again, has saved material, has reduced productive costs.
Description of drawings
Fig. 1 is the structural representation of the special-purpose detachable lifting-point device of this double-feedback aerogenerator group after engine room base.
Among the figure: 1 detachable hanger, 2 steel structures are with high strength bolt, 3 base top panels, 4 reinforced plates.
Further specify below in conjunction with the specific embodiment of accompanying drawing the utility model.
The specific embodiment
Referring to Fig. 1; The special-purpose detachable lifting-point device of this double-feedback aerogenerator group after engine room base; Comprise hanger 1 and bolt 2; Said bolt 2 is used high strength bolt for steel structure, and said hanger 1 is fixedly mounted on the base top panel 3 of double-feedback aerogenerator group after engine room with high strength bolt through steel structure.Described hanger 1 is detachable; Detachable hanger 1 can be dismantled with high strength bolt through the dismounting steel structure and remove after the installation; Thereby master control cabinet door can be opened bigger angle, and convenient electric service personnel is safeguarded, has also made things convenient for the walking in the cabin to a certain extent.In addition, detachable hanger 1 can be transported to ground through lifting machine in the cabin, can use in all the other base cocycles again, has saved material, has reduced productive costs.Also comprise reinforced plate 4, said reinforced plate 4 is fixedly mounted on the base top panel 2 of double-feedback aerogenerator group after engine room.Through reinforced plate 4 is set, make base top panel 3 can bear enough big bearing capacity.Said reinforced plate 4 is welded on the lower surface of the base top panel 3 of double-feedback aerogenerator group after engine room.Through reinforcement of weld plate 3, reinforced plate 4 is fully captiveed joint, with base top panel 3 so that base top panel 3 can bear enough big bearing capacity.The base top panel 3 of said hanger 1, double-feedback aerogenerator group after engine room and reinforced plate 4 be provided with steel structure with the suitable screw of high strength bolt.Steel structure passes screw and the screw on the hanger 1 on base top panel 3 and the reinforced plate 4 with high strength bolt; And with screw be screw thread fit; Under the cooperation of nut, can detachable hanger 1 be fixed on the base top panel 3, on the other hand on the one hand simultaneously; Use high strength bolt through the dismounting steel structure, realized the detachable function of hanger 1.
