The bottom drives electric door
Technical field
The utility model relates to electric door, relates in particular to that to can be applicable to aerial suspension be the electric door in the coating equipment of mode of movement.
Background technology
At present, the electric door structure that in coating equipment, generally adopts is combined by top-drive device, door body and bottom guiding device.Owing to contain heavier elements such as reductor, strainer in the drive unit; Can increase the difficulty of installing and keeping in repair so it is installed on a body top, in addition, be in the coating equipment of mode of movement with aerial suspension; Drive unit is installed on a body top; Must two cover symmetries install, thereby complex structure, cost is higher.
The utility model content
The purpose of the utility model is to propose a kind of bottom and drives electric door, to solve existing coating equipment with electric door installation and maintenance difficult, complex structure, problem that cost is high.
For reaching this purpose, the utility model adopts following technical scheme:
A kind of bottom drives electric door, comprises a body, drive unit and guiding device, and the bottom of said door body is provided with drive unit, and the top is provided with guiding device.
Preferably, said bottom drives electric door and also comprises track, rail wheel and junction plate, and said rail wheel is installed in the bottom of a body; Said door body places on the said track; And contact with track through said rail wheel, said drive unit comprises decelerator, drive sprocket, chain and strainer, said drive sprocket is installed on the power output shaft of said decelerator; Said chain is arranged on drive sprocket and the strainer, and said door body is connected with said chain through junction plate.
Preferably, said guiding device comprises installation shaft, guide bearing and guide rail, and said installation shaft vertically is arranged on the upper end of a body, and said guide bearing is installed in the upper end of said installation shaft, and stretches in the gathering sill of guide rail.
Preferably, said decelerator and strainer are separately positioned on the two ends of said track.
Preferably, said track is an angle steel, and Open Side Down is arranged on the track support.
The operating principle of the utility model is: through will heavier drive unit placing the bottom of a body, guiding device is placed the top of a body, install and the difficulty of maintenance activity thereby reduce; Eliminate safe hidden trouble, improve the steadiness and the safety of electric door structure simultaneously, in addition; Owing to will heavier drive unit have placed the bottom of door body, no longer need two cover drive units symmetries to install, only overlapping drive unit with one can meet the demands; Thereby simplify the structure, reduced cost.
The beneficial effect of the utility model is: more simple, the firm and safety of structure, easy to installation and maintenance, cost is low.
