Description

The wind-power tower hatch door

Technical field

The utility model relates to a kind of door, refers in particular to the hatch door that is installed in the wind-power generating system on the pylon cylindrical shell.

Background technique

In the wind-power generating system, electric power facility and being used to is constructed and the cat ladder safeguarded is arranged in the generator pylon cylindrical shell usually, enter in the pylon for ease of operator the miscellaneous equipment in electric power facility and the power generation system is carried out M R, pylon bottom shell ring is provided with the hatch door that is comprising doorframe and door-plate usually.

The hatch door doorframe of existing application on the wind tower is an overall structure, this overall structure doorframe is with the square plate of steel plate cut growth, after the pre-bending of plate bending rolls roll bending, re-use press machine press-bending setting, the door opening place that opened in advance to the shell ring body of pylon bottom of integral solder then, this overall structure doorframe manufacture difficulty in manufacturing process is bigger, often needing to set up some special-purpose operations and frock can finish, so just increased manufacture cost, and it is more because of operation in manufacture process, produce cumbersome, seriously restricting the raising of manufacturing efficiency, the obviously this mode that doorframe is carried out whole manufacturing exists the manufacture cost height, the defective that manufacturing efficiency is low, and make good overall structure doorframe because of volume, weight is all bigger, brought suitable trouble to installation, existed inconvenient defective is installed; And the door-plate that matches with the hatch door doorframe on the wind tower is the individual layer steel plate, this single layer board structure door-plate is difficult to install additional anti-theft device, the anti-theft feature fragility, facility is subject to artificial destruction in the tower, and in case there is the layman to enter in the wind tower, electric power facility also can constitute a threat to layman's life in the tower, and therefore this single layer board structure door-plate exists anti-theft feature poor, uses unsafe defective.

The model utility content

Technical problem to be solved in the utility model provides a kind of easy for installation, wind-power tower hatch door that Safety performance is good.

In order to solve the problems of the technologies described above, wind-power tower hatch door of the present utility model comprises doorframe, door-plate, and described doorframe is a splicing construction, and described door-plate flexibly connects mutually with doorframe,

After adopting said structure, because doorframe is set to splicing construction, the doorframe make is changed, be that doorframe is become the splicing construction that is combined by the multistage doorframe by original overall structure, the corresponding doorframe machining manufacture is also become by original integral body processing processed separately the difference of each section doorframe, so not only reduced difficulty of processing, and saved special-purpose operation and the frock of being used when integral production is made, saved cost of production, reduced the production time, it is simple and convenient to have manufacturing, advantage of high production efficiency; When this splicing construction doorframe is assembled, only need each section doorframe spliced successively along door opening edge on the cylindrical shell and weld, because of each section doorframe volume less, lighter weight, then operation is very easy, obviously has advantage easy for installation; Because door-plate is set to flexibly connect mutually with doorframe, then made things convenient for open and close again, had advantage easy to use hatch door.

Preferred implementation of the utility model is, described splicing construction doorframe is at least two sections, existingly when this setup has been avoided whole doorframe processing is difficult to process, the defective of complex procedures, have make simple and convenient, advantage of high production efficiency; And the doorframe sectional shape is set to snap ring shape, directly bayonet socket is connected in the edge of door opening during installation, and welding back doorframe intensity obtains increasing, and the pick-proof performance of hatch door is improved, and has good Security.

Another preferred implementation of the utility model is, door-plate is set to the box like structure of hollow, make the linkage mechanism that the pulling dead bolt is installed in the door-plate become possibility by this set, overcome the existing defective that is difficult to install anti-theft device of original single layer structure door-plate, had the high advantage of Safety performance.

Description of drawings

Below in conjunction with the drawings and specific embodiments welding of the present utility model is described further with the operational window door device.

Fig. 1 is the work structuring schematic representation of a kind of embodiment of the utility model hatch door;

Fig. 2 is along the cross section view at A-A place in the structure shown in Figure 1.

Among the figure, 1-cylindrical shell, 2-doorframe, 3-door-plate, 4-linkage mechanism, 5-dead bolt, 6-handle, 7-cipher lock.

Embodiment

At Fig. 1, in the hatch door shown in Figure 2, hatch door is made of doorframe 2 and door-plate 3, doorframe 2 is four sections, the sectional shape of doorframe 2 is a snap ring shape, doorframe 2 is connected in the door opening edge and joins end to end successively, door opening is arranged on the cylindrical shell 1, doorframe 2 is fixedly connected by welding and cylindrical shell 1, the doorframe 2 that this segmentation is provided with, not only overcome original whole doorframe 2 add man-hour existing be difficult to processing, the defective of complex procedures, it is simple and convenient to have obtained manufacturing, advantage of high production efficiency, and overcome original whole doorframe 2 because of volume, the all bigger defective that is not easy to install that produces of quality has obtained to make things convenient for the effect of installing; And doorframe 2 is connected in the door opening edge and fixes with cylindrical shell 1, doorframe 2 intensity are enhanced, the pick-proof performance of hatch door is improved, and has obtained good Security.Door-plate 3 matches with doorframe 2 and flexibly connects mutually by hinge 8 and doorframe 2, door-plate 3 is one to be set to the box like structure of hollow, on door-plate 3 outer surfaces, cipher lock 7 is installed, handle 6 also is not installed on door-plate 3 outer surfaces, handle 6 is installed on cipher lock 7 tops, linkage mechanism 4 is installed in door-plate 3, this linkage mechanism 4 flexibly connects mutually with cipher lock 7 dead bolts 5, dead bolt 5 inserts under working condition on the doorframe 2 in the default jack, this hatch door that installs cipher lock 7 on door-plate 3 additional has been realized high safe antitheft performance.

When doorframe 2 is installed, doorframe 2 is connected in the door opening edge also to join end to end successively, each section doorframe 2 is fixedly connected by welding and cylindrical shell 1, simultaneously the splicing seam of 2 on each section doorframe is welded, then splicing place weld seam is carried out polishing, with cipher lock 7 and shake hands 6 to be installed on door-plate 3 surfaces, linkage mechanism 4 is installed in the door-plate 3, and cipher lock 7 dead bolts 5 are flexibly connected mutually with linkage mechanism 4, when hatch door is closed, dead bolt 5 is inserted in the jack of opening in advance on the doorframe 2 by linkage mechanism 4, when need are opened hatch door, by linkage mechanism 4 dead bolt 5 is pulled out from doorframe 2 jacks, the handle 6 of holding with a firm grip outwards firmly can be opened hatch door.

Above-mentionedly only enumerated some preferred implementations of the utility model hatch door, but be not limited to this,, also can do some conversion and improvement under the situation of the utility model basic principle.For example, the segmentation of doorframe is not limited only to four sections, also can be greater than or less than four sections, and so on.So long as the hatch door doorframe is set at least two sections, the box-like layout that door-plate is set to hollow all is considered as falling into protection domain of the present utility model.
