Abstract
The utility model relates to a double-track electric flexible door, comprising a frame 4, a power unit arranged on the frame 4, a flexible door body connected with the power unit, a plurality of active traveling wheels 7 and a plurality of traveling wheel 3 arranged on the bottoms of the frame 4 and the flexible door body; wherein, a plurality of wheel flanges 6 are arranged on the edges of the active traveling wheel 7 and the traveling wheel 3. The utility model has the advantages of low noise, performing on a straight line, no running deviation, all the traveling wheels always landing and long service life.
Description
Technical field: the utility model belongs to a kind of door, particularly a kind of double track electric extendable door, i.e. the outdoor use gate of factory, office and other units.
Background technology: the gate mouth at factory, office or other unit is equipped with Power-driven gate at present, when pedestrian or vehicle turnover, is opened or closed by door position personnel control.Its structure is: a telescopic door body is arranged, and the door body moves frame by several and the plurality of portable rod hinge connection constitutes.Road wheel is equipped with in bottom at mobile frame.In a termination frame of door body, dynamic device is connected with the positive transport wheel of frame bottom on the frame.During installation one side of door body is fixed on one side of big doorframe, the opposite side of door body is promptly met sb. at the airport a side of frame and power set for moving freely end.When the power set energising, the positive transport wheel of frame bottom is rotatable under the driving of power set, the road wheel that drives mobile frame bottom simultaneously rotates, all road wheel all is located in ground, because door folded body connecting rod is the quadrangle hinge-like, the door body can reach flexible purpose with the road wheel left-right rotation, makes the gate close or open.The retractable door of this structure has following shortcoming: because the road wheel outside is the flat cylinder of light, directly be located in ground, big, the easy sideslip of noise during walking, time is long slightly, and uneven phenomenon appears in ground, causes the part road wheel not land, move not steadily, application life is short.
Summary of the invention: the purpose of this utility model provides that a kind of noise is little, linear running, not sideslip, whole road wheel double track electric extendable doors that can land simultaneously all the time.
Technical solution of the present utility model is: a kind of double track electric extendable door, it comprises frame 4, frame 4 is provided with power set, and connect the retractable door body, described frame 4, retractable door body bottom are provided with positive transport wheel 7 and road wheel 3, and it is characterized in that: the edge of positive transport wheel 7 and road wheel 3 is provided with wheel rim 6.
The utility model has compared with prior art that noise is little, linear running, not sideslip, all road wheel can land simultaneously all the time, operates steadily, the life-span is long advantage.
Description of drawings: Fig. 1 is the utility model specific embodiment structural representation;
Fig. 2 is that A-A shown in Figure 1 amplifies cross-sectional schematic;
Fig. 3 is that D-D shown in Figure 1 amplifies cross-sectional schematic.
The specific embodiment: following the utility model is further described:
As shown in the figure: a telescopic door body is arranged, and the door body is moved by several that frame 1 and plurality of portable connecting rod 2 are hinged to be constituted.In the bottom of mobile frame 1 road wheel 3 is housed.In a termination frame 4 of door body, dynamic case 5 on the frame 4, power set are positioned at headstock 5.Power set are connected with positive transport wheel 7 chains of frame 4 bottoms.On the edge of positive transport wheel 7, road wheel 3, be provided with a wheel rim 6, wheel rim 6 and road wheel 3, positive transport wheel 7 all be structure as a whole (referring to Fig. 2).During installation one side of door body is fixed on one side of big doorframe, the opposite side of door body is promptly met sb. at the airport a side of frame 4 and power set for moving freely end.Be equipped with the track 8 that matches with positive transport wheel 7, road wheel 3 on the ground.Mobile frame 1 adopts axle to be connected with folding connecting rod 2, and with overlapping 9 as sliding bearing, the material of cover 9 is: polyvinyl chloride between axle and the folding connecting rod 2.Door integral body can orbit during work, reach that noise is little, linear running, not sideslip, all road wheel all the time simultaneously land, operate steadily, purpose that the life-span is long.
