Abstract
The utility model relates to the technical field of flexible door and especially indicates a railless automatic flexible door which is applied to be used at various kinds of entrances and exits. A technical proposal of the utility model is that a flexible frame is connected between a fixing unit and a machine head and is mutually articulated with the fixing unit and the machine head; the bottoms of the flexible frame and the machine head are provided with a plurality of idler wheels; an infrared receiver is installed at the fixing unit; an infrared emitter is installed at the machine head and is connected with an infrared emitting circuit; the machine head is provided with a motor which is controlled by a motor control system; the motor drives a left idler wheel and a right idler wheel at same side of the bottom of the machine head by a gear transmission mechanism. After the device is adopted, an infrared detecting system can be used to correct the deviation of the machine head in time during the course of running to ensure that the machine runs along the straight line and according to really realize the purpose of the railless flexible door.
Description
Technical field:
The utility model relates to the retractable door technical field, refers in particular to a kind of automatic retractable door of trackless that is suitable in various import and exports uses.
Background technology:
At present, all used automatic retractable door at the place, gate of many offices, enterprises and institutions.Thisly mainly replaced original plug-type gate gradually with electric motor driven retractable door, it is not only easy to operate, and when the use advantage such as little that takes up room is arranged.At present in order to ensure retractable door close with opening process in move along a straight line, below retractable door, all be equipped with fixing track, make its close or opening process in the middle of orbital motion.So, not only make retractable door complex structure, make loaded down with trivial detailsly, and also make troubles to its installation.Designed trackless extensible door at this situation people, for example the disclosed patent No. is the utility model patent of " 97240967.x " in the Chinese patent manual, it mainly utilizes flexible guide rod to control the rectilinear motion of retractable door, but this mechanism is easy to occur deviation, and retractable door can't be made timely deviation automatically and correcting, and is difficult to guarantee the rectilinear motion of trackless extensible door.
Summary of the invention:
The purpose of this utility model is to provide a kind of infrared detection system control gate body that utilizes to keep rectilinear motion, and is suitable for the automatic retractable door of trackless in various import and exports uses.
The utility model is achieved by the following technical solution: expansion bracket is connected between fixture and the head, and is hinged with it, and the bottom of expansion bracket and head is equipped with some rollers, and infrared receiver is installed on the fixture; RF transmitter is installed on the head, and is connected with infrared transmitter; Motor by electric machine control system control is installed on the head, and motor drives the left and right roller of head bottom homonymy by gear drive.
After adopting this device, though utilize the infrared detection system can the correction head deviation of being expert at and occurring in the middle of sailing, guarantee it along straight-line travelling, thus from truly having realized the purpose of retractable door trackless.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1 is a systematic schematic diagram of the present utility model;
Fig. 2 is the cut-away view of head in the utility model;
Fig. 3 is the front view of the utility model one specific embodiment;
Fig. 4 is the vertical view of the utility model one specific embodiment.
The specific embodiment:
See accompanying drawing 1,2,3,4, the utility model comprises: fixture 1, expansion bracket 2 and head 3, expansion bracket 2 are connected between fixture 1 and the head 3, and are hinged with it, and the bottom of expansion bracket 2 and head 3 is equipped with some rollers 4.Infrared receiver 51 is installed on the fixture 1; RF transmitter 52 is installed on the head 3, and is connected with infrared transmitter; Motor 31,32 by electric machine control system control is installed on the head 3, and motor 31,32 drives the left and right roller 41,42 of head 23 bottom homonymies by gear drive 34.
Described electric machine control system comprises signal processing circuit, control circuit, frequency changer circuit composition.
When using the utility model, in the process of closing the door, infrared transmitter sends infrared light beam by being installed in the RF transmitter 52 on head 3 tops in head 3 runnings.When head 3 straight-line travellings, the infrared rays that RF transmitter 42 is launched will be received by the infrared receiver 512 of centre, after the signal processing circuit processing, the signal of normally operation is outputed to control circuit, export mains supply to left and right sides motor 31,32 by control circuit, make left and right sides motor 31,32 with same frequency, rotation speed operation, keep left and right sides roller 41,42 with fast straight-line travelling.When head 3 is taken back when travelling, the infrared rays that RF transmitter 52 is launched will be received by right infrared receiver 513, signal is after signal processing circuit is handled, the signal of output head 3 left avertences is to control circuit, control circuit will carry out frequency conversion (frequency reducing) to the power supply of importing right motor 32 then, the power supply of left side motor 31 inputs is constant, the rotating speed of so right motor 32 reduces, the speed of right roller 42 reduces, and left motor 31 keeps original frequency, and the travel speed of left wheel 42 is constant, makes left and right sides roller 41,42 travel speed produces speed difference, to correct the deflection of head 3, until head 3 straight-line travellings.When head 3 takes over when travelling, the infrared rays that RF transmitter 52 is launched will be received by left infrared receiver 511, signal is after signal processing circuit is handled, the signal of output head 3 right avertence is to control circuit, control circuit will carry out frequency conversion (frequency reducing) to the power supply of importing left motor 31 then, the power supply of right motor 32 inputs is constant, the rotating speed of so left motor 31 reduces, the speed of left wheel 41 reduces, and right motor 32 keeps original frequency, and the travel speed of right roller 42 is constant, makes left and right sides roller 41,42 travel speed produces speed difference, to correct the deflection of head 3, until head 3 straight-line travellings.And so forth, head 3 will remain straight-line travelling.In the process of opening the door, the infrared detection system will be closed, and the power supply of control system output same frequency makes it keep identical speed to travel to left and right sides motor 31,32, and head 3 relies on the traction of expansion bracket 2 to realize straight-line travelling.Head 3 will remain straight-line travelling in whole process like this, thereby make the utility model realize the purpose of trackless.
