(1) built-in guiding carriage is oriented to bottom beam: directive wheel includes the first directive wheel 17.31 and second to wheel 17.34, for being oriented to bottom beam, and the first directive wheel 17.31, second is rolling friction between 17.34 and bottom beam to taking turns, favorably It is moved in bottom beam.First directive wheel 17.31, the first support wheel 17.32, the second support wheel 17.33 and the second directive wheel 17.34 dress Into the support guide cavity 19 of the second bottom beam 19, bracket 17.35 is set to opening, and 18 bottom of the first bottom beam is caught in guide plate In 17.2, the first bottom beam 18 is fixedly connected with guide plate 17.2, because between guide plate 17.2 and support guide wheel assembly 17.3 Distance it is constant, therefore, the spacing of the first bottom beam 18 and the second bottom beam 19 remains unchanged, and realizes to the base beam section Support and guiding, it is ensured that the base beam section can stablize movement, and, it can be ensured that the base beam section is moved along straight line It is dynamic, it is unlikely to stuck.

(2) new work transmission adjusts speed of the bottom beam to neighbouring bottom beam conveying power:

Motor drives driving wheel 5.1 to rotate, and driving wheel 5.1 drives the first bottom beam 18 mobile by straight chain 2.1；Driving wheel 22.3 obtain power by circulation link chain, and driving wheel 22.3 drives drive sprocket 22.5, drive sprocket by driving shaft 22.4 22.5 drive drive sprocket 22.7 by driving chain 22.8, and drive sprocket 22.7 drives driving wheel by transmission shaft 22.2 22.6, driving wheel 22.6 is set in the second bottom beam 19, and the straight chain 2.1 being arranged in driving wheel 22.6 and the second bottom beam 19 engages, To realize the second bottom beam 19 and the equidirectional synchronizing moving of the first bottom beam 18, completes to open the door and close the door.Built-in guiding carriage 16 ensure that the first bottom beam 18 and 19 spacing of the second bottom beam remain unchanged, and driving wheel 5.1 and straight chain 2.1 in the first bottom beam 18 and follow The back lash of loop chain item remains unchanged, and meshing relation is stablized；Driving wheel 22.3 is remained unchanged with circulation link chain back lash, is nibbled Conjunction relationship is stablized；Therefore, driving wheel 22.6 is remained unchanged with 2.1 back lash of straight chain in the second bottom beam 19, meshing relation Stablize；Power transmitting keeps stablizing, and the first bottom beam 18 and the second bottom beam 19 can stablize transmission power, moreover, being able to maintain the One bottom beam 18 is remained with the second bottom beam 19 and is moved in parallel, and is unlikely to mutual clamping in moving process.

If the second bottom beam 19 also needs the third bottom beam to neighbouring setting to convey power, needed in the second bottom beam 19 corresponding Circulation link chain is set, and 22.6 bottom of driving wheel is meshed with circulation link chain bottom chain 6.1 in the second bottom beam 19, the second bottom beam 19 New work transmission 24 described in interior corresponding inserting, the driving wheel 22.3 of the new work transmission 24 in the second bottom beam 19 In the circulation link chain of the second bottom beam 19, the driving wheel 22.6 of the new work transmission in the second bottom beam 19 is set to In third bottom beam, the circulation link chain in the second bottom beam is corresponded to, circulation link chain bottom is equipped with engagement supporting bar 7.1 in the second bottom beam, really The second bottom beam inner driving wheel 22.6 is protected to engage with circulation link chain.Similarly, if third bottom beam does not need to convey power outward, only Straight chain 2.1 is set in third bottom beam, if necessary to conveying power outward, then circulation is accordingly set in third bottom beam Chain, and the new work transmission is set in third bottom beam, and so on, it can be set according to actual needs right quantity Bottom beam.Because the second bottom beam is on the basis of the first bottom beam is mobile, therefore, it is necessary to appropriate adjustment transmission ratios, adjust Movement speed of whole second bottom beam with respect to the first bottom beam, it is ensured that in the same time, the first bottom beam and the second bottom beam are all completed to close the door Mobile distance is needed with opening the door.

3, be oriented to: the first bottom beam 18 and the second bottom beam 19 are arranged side by side, and side guiding cavity 12 is provided with side directive wheel, and side is led The second bottom beam 19 is connected to wheel, for being oriented to the second bottom beam 19, it is ensured that the second bottom beam 19 and the opposite edge of the first bottom beam 18 Linear motion avoids mutually stuck in 19 motion process of the first bottom beam 18 and the second bottom beam.

4, dust-break is antifreeze: the first block brush slot 4 and the second block brush slot 14, inserts the first block brush 20 and the second block brush 21 Afterwards, it can prevent dust and rain, snow etc. from entering inside base beam section, avoid icing or dirt accumulation in base beam section, influence Base beam section inner driver and guiding device operate normally, and transmission device includes driving wheel and new work transmission；Guiding device It further include the support guide sliding dress of the adjustable hanging device of the external driving device of electrically operated gate including built-in guiding carriage It sets.The especially cold districts such as northeast, winter, rainwater or snow are easily accessible the driving wheel cavity or side guiding cavity of opening setting It is interior, cause to freeze, influences electrically operated gate normal operation.

To the description in the direction of structure and relative positional relationship in the utility model, such as all around above and below description, Limitations of the present invention are not constituted, only for convenience of description.
