Described girder 105 is a rectangular frame structure, and its soffit is connected with the upper surface of rotation wing erection loop, hangs the rotation wing on the soffit owing to rotation wing erection loop, therefore when rotating under the driving of girder 105 at driving wheel, can rotate by the driven rotary wing.
The number of described driving wheel 101 is two, is positioned at two relative on the girder 105 angles, is used for rolling at the control lower edge of drive unit circular guideway, drives girder 105 rotations.
The number of described driven pulley 102 is two, is positioned at two angles in addition relative on the girder 105, is used for rolling along circular guideway, and girder 105 is played a supporting role.
Described intermediate transverse girder 103 is positioned on the axis of symmetry of girder 105, by two independently beam form, the structure of girder 105 is played a supportive role.
103 one-tenth oblique angles of described level and smooth door brace summer 104 and intermediate transverse girder are mainly used in the bottom and hang level and smooth.
As seen, the rotating beam assembly of prior art automatic revolving door, because girder is a rectangular frame structure, four fulcrums can only be arranged on circuit orbit, i.e. two driving wheels and two driven pulleys, if hang larger-size rotation wing peace slide, can make girder produce bigger flexible deformation, thereby limit the size of the door body that is hung; On the other hand, four the fulcrum discontinuity of girder on circuit orbit with the rotation of girder is stablized inadequately, easily produce noise.
The utility model content
In view of this, the purpose of this utility model is to provide a kind of rotating beam assembly of automatic revolving door, and it is less that this rotating beam assembly produces the flexible deformation, to hang the door body of large-size; On the other hand, the fulcrum on this rotating beam assembly is stressed evenly, makes to be difficult for producing noise by spin stabilization.
The technical solution of the utility model is achieved in that
A kind of rotating beam assembly of automatic revolving door, key are that this rotating beam assembly comprises: girder, driving wheel, support wheel and intermediate transverse girder;
Described girder is a quadrilateral structure, and two wherein relative limits are the arc beam, and two relative in addition limits are linear shape beam;
On every arc beam of described girder a driving wheel is installed, and this driving wheel is positioned at the position of centre of gravity of arc beam; On every arc beam of described girder at least two support wheels are installed also, these support wheels are distributed in the both sides of driving wheel;
The two ends of described intermediate transverse girder are connected on two arc beams of girder.
Preferably, described intermediate transverse girder is two, and is arranged in parallel, and wherein the cross section of every intermediate transverse girder all is the I font.
Preferably, be connected with at least two junction plates between two intermediate transverse girders; Also be hung with level and smooth door brace summer on the soffit of described junction plate.
Preferably, also comprise four spokes in this rotating beam assembly, an end of every spoke connects the arc beam of girder, and the other end connects intermediate transverse girder, and per two spokes are one group and are positioned on the straight line.
Preferably, two of described girder linear shape beams are realized by spoke.
As seen, in the rotating beam assembly in the utility model, girder has at least six fulcrums, will produce less flexible deformation, can hang larger-size door body.On the other hand,, therefore driving wheel is installed in this position, again support wheel is installed in the position of driving wheel both sides because the position of centre of gravity of arc beam is the position of stressed maximum, can make that each takes turns stressed evenly, thereby make spin stabilization, be difficult for producing noise.
Description of drawings
Fig. 1 is the structural representation of the rotating beam assembly of automatic revolving door in the prior art;
Fig. 2 is the structural representation of the rotating beam assembly of automatic revolving door in the utility model.
The specific embodiment
For making objects and advantages of the present invention clearer, the utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 2 is the structural representation of the rotating beam assembly of automatic revolving door in the utility model, comprising: girder, driving wheel 201, support wheel 202 and intermediate transverse girder 205.
Above-mentioned girder is a quadrilateral structure, and wherein relative two is arc beam 203, and two relative in addition limits are linear shape beam 204.
On above-mentioned every arc beam 203 driving wheel 201 is installed all, the installation site of driving wheel 201 is positioned at the center of gravity of place arc beam 203.On above-mentioned every arc beam 203 two support wheels 204 are installed also, lay respectively at the both sides of driving wheel 201.
Therefore in the rotating beam assembly in the utility model, girder has six fulcrums, will produce less flexible deformation, can hang larger-size door body.On the other hand, because the position of centre of gravity of arc beam 203 is positions of stressed maximum, therefore driving wheel 201 is installed in this position, calculate the position that support wheel 202 is installed in driving wheel 201 both sides according to general mechanics principle again, can make that each takes turns stressed evenly, thereby make spin stabilization, be difficult for producing noise.The number of above-mentioned support wheel also can be greater than two.
Above-mentioned every linear shape beam 204 all adopts spoke to realize, this is because the main effect of linear shape beam 204 is to support, spoke simple in structure, but can well play the effect of support, therefore adopt spoke to realize that linear shape beam 204 can be on the basis of realizing support function, save material, install also very convenient.
