Description
The technical field is as follows: the utility model relates to a drive door-hinge system of electrically operated gate.
Background art: the driving motors of a plurality of electric rotating doors are all installed in the door leaves, the main transmission part is also arranged in the door leaves, although the installation space is large, the transmission route is easy to arrange, the whole universality is not strong, the structure is not compact, and the electric rotating doors cannot be naturally applied to door frames of various different door leaves and are not beneficial to the transformation and maintenance of the electric doors.
The invention content is as follows: not enough to prior art, the utility model provides an electrically operated gate axle system that the commonality is strong.
The utility model discloses a vertical rotatable pivot of arranging in side door frame department, the door leaf uses the pivot to be rotation center and connect with pivot transmission, be fixed with the motor on the door frame of side, the vice input of worm gear is connected to the motor, the vice output of worm gear is connected to vertical intermediate rotating shaft, the outside clearance cover of intermediate rotating shaft has the axle sleeve, through the vice transmission cooperation of damping friction between axle sleeve and the intermediate rotating shaft, the end connection of axle sleeve has drive gear, connect the door shaft gear and the drive gear meshing transmission at the pivot tip, constitute door leaf actuating mechanism.
The utility model provides a motor and transmission part are all in the vertical arrangement of side door frame department, and the structure is very compact, and holistic commonality is strong, and various door leafs all can connect and be suitable for. In the electric opening and closing process, if the door leaf is blocked, the damping friction pair can immediately slip, the motor can not drive the door leaf to open and close any more in idle running, and the door leaf can be pushed and stopped randomly and can be manually opened and closed like a common door. When the block is eliminated, the damping friction pair immediately restores the transmission without slipping, and the door leaf continues to be electrically opened and closed. The whole design is reasonable, the safety is good, no circuit control needs to be added, and the reliability is high.
The invention is further described with reference to the following figures and examples.
Description of the drawings: FIG. 1 is a schematic view of the installation and use state of the embodiment.
Fig. 2 is an enlarged schematic view of a-a section of fig. 1.
Fig. 3 is an enlarged schematic view of a section B-B of fig. 2.
The specific implementation mode is as follows: as shown in fig. 1 to 3, the rotatable pivot 3 is vertically disposed at the side doorframe 1, the door leaf 2 takes the pivot 3 as the rotation center and is in transmission connection with the pivot 3, in this embodiment, the door leaf 2 is in transmission connection with the pivot 3 through the bracket mechanism 13. A motor 4 is fixed on the door frame 1 on the side edge, the motor 4 is connected with the input end of a worm gear pair 5, and a vertical middle rotating shaft 6 is connected with the output end of the worm gear pair 5. The outer clearance cover of middle pivot 6 has axle sleeve 7, and through the vice 8 transmission cooperation of damping friction between axle sleeve 7 and the middle pivot 6, the end connection of axle sleeve 7 has drive gear 9, connects the meshing transmission of door shaft gear 10 and drive gear 9 at pivot 3 tip, constitutes door leaf actuating mechanism.
When the motor 4 works, the middle rotating shaft 6 is rotated through the transmission of the worm gear pair 5, the shaft sleeve 7 rotates together with the driving gear 9 under the driving action of the damping friction pair 8, the door shaft gear 10 rotates together with the pivot shaft 3, and the linked support mechanism 13 drives the door leaf 2 to rotate around the pivot shaft 3 for opening and closing.
If the door leaf 2 is blocked and stopped in the opening and closing process, the pivot 3 is forced to be relatively stopped, but the motor 4 is still working, the middle rotating shaft 6 rotates due to the fact that the transmission torque of the worm and gear pair 5 is larger, the damping friction pair 8 between the shaft sleeve 7 and the middle rotating shaft 6 is forced to immediately slip, and the motor 4 idles, namely the door leaf 2 can be pushed to stop freely by hand, and can be manually opened and closed like a common door. When the block is eliminated, the damping friction pair 8 immediately restores the transmission without slipping, and the door leaf 2 continues to be electrically opened and closed.
The damping friction pair 8 actually consists of friction plates fixed on the shaft sleeve 7 and the intermediate rotating shaft 6 respectively, a pressing sleeve 11 and a pressure spring 12 are arranged in a gap between the shaft sleeve 7 and the intermediate rotating shaft 6 in the embodiment, and the pressing sleeve 11 presses and contacts the damping friction pair 8 to form a damping adjusting mechanism. Therefore, the friction resistance between the friction plates can be adjusted by changing the pressure on the damping friction pair 8, namely the damping force of the damping friction pair 8.
In order to make the layout more reasonable, the motor 4 is also vertically arranged, the worm gear pair 5 of the embodiment contains two pairs of worm gears which are mutually driven, and the axial directions of the input end and the output end of the worm gear pair 5 are the same, so that the motor 4, the middle rotating shaft 6 and the pivot shaft 3 are vertical, and the whole body can be assembled into a vertical electric door shaft which is more compact and beautiful when being arranged on the door frame 1 at the side edge.
