Abstract
Disclosed is a flexible lifting door which comprises a door body, an electromechanical device, guide rails, a top beam, a driving shaft, a counterweight bottom beam and lifting belts, wherein the guide rails are arranged on two sides of the door body, the top beam is disposed on the upper portion of the door body, the driving shaft is arranged inside the top beam, the counterweight bottom beam is arranged at the bottom of the door body, and the lifting belts pass through the door body. The upper ends of the lifting belts are fixed onto the driving shaft; the lower ends of the lifting belts are connected with the counterweight bottom beam; a plurality of detecting switches for detecting breakage of the lifting belts are further arranged inside the top beam; each detecting switch is respectively close to each lifting belt; and the detecting switches are electrically connected with the electromechanical device and an alarm. By adopting a plurality of the lifting belts to lift the door body, the door body can be ensured to be opened smoothly, and noise produced in operational process is reduced to the minimum. The detecting switches can timely discover the working condition of each lifting belt, and gives an alarm in the first time when one of the lifting belts is broken, and then the door body can stop running to facilitate timely repairing, thereby preventing other lifting belts from overload work and further prolonging the service life of the lifting door.
Description
Technical field
The utility model relates to a kind of flexible overhead door, particularly a kind of flexible door with multiple spot lift-type structure.
Background technology
Shortcomings such as instability appear promoting in the flexible overhead door of multiple spot lift-type in the market, door body regular meeting in lifting process because of a variety of causes; The quality of its body own is heavier simultaneously, the elevator belt that is mainly used in the lever gear door body is in directly visual detection of a body inside, when wherein an elevator belt ruptures, deflection can take place during the lifting of door body, though perhaps normally lifting of door body, but remaining elevator belt is owing to surpass rated load work, also can rupture very soon, for the user brings potential safety hazard, simultaneously also can this will influence the application life of a body, so the balance gate body weight is for playing very crucial effect the application life of overhead door.
The utility model content
The purpose of this utility model provides a kind of flexible overhead door,
For achieving the above object, the technical solution adopted in the utility model is: a kind of flexible overhead door comprises:
The flexible door body, the internal placement of described door body has many elevator belts, and the bottom of described door body is provided with the counterweight bottom girder;
Electromechanical assembly is used to furl or loosens described elevator belt;
Guide rail be arranged on the both sides of described door body, and the both sides of described door body is slidingly installed in described guide rail;
Back timber is arranged on the top of described door body, and the inside of described back timber is provided with power transmission shaft rotationally, and described power transmission shaft is in transmission connection mutually with described electromechanical assembly;
The upper end of many described elevator belts all is fixed on the described power transmission shaft, and the lower end of many described elevator belts is connected with described counterweight bottom girder;
The inside of described back timber also is provided with a plurality of sense switches that described elevator belt snaps that are used to detect; Each described sense switch is close to each described elevator belt respectively, and described sense switch is electrically connected with described electromechanical assembly.
Preferably, described sense switch is a microswitch, and each described sense switch all comprises contact, and each described contact closely contacts mutually with each described elevator belt respectively.
Perhaps, described sense switch is an optoelectronic switch.
Preferably, many described elevator belts are evenly distributed on the inside of described door body.
Further, described electromechanical assembly also includes alarm, and described alarm is electrically connected with described sense switch.
The utility model compared with prior art has following advantage: the utility model adopts multiple spot lift-type structure lever gear door body, have open smooth and easy, the advantage that noise is low; The situation that sense switch monitors elevator belt at any time is set, in case one of them elevator belt fracture, sense switch can issue a signal to electromechanical assembly immediately, and falls the noise that produces in the running minimum; The warning system of She Zhiing has increased safety factor greatly simultaneously, guarantees the safe operation of door body.
