Embodiment
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present invention are described in a schematic way, and therefore it only shows the formation relevant with the present invention.
The specific embodiment of the rolling open and close machine gate height detection device for winding of the present invention as shown in Fig. 1 ~ 4, a kind of rolling open and close machine gate height detection device for winding, comprise reduction gear 1, display device 2 and the coupling shaft 3 be coaxially arranged on the gear shaft of rolling open and close machine, the input shaft of reduction gear 1 is fixedly connected with coupling shaft 3 one end, coupling shaft 3 other end is also provided with absolute type photoelectric encoder, display device 2 is arranged on the output shaft of reduction gear 1, reduction gear 1 comprises worm gear 11, worm screw 12, outer cover 13, support 14, flange 15 and installation shaft 16, reduction gear 1 is arranged in outer cover 13, outer cover 13 is arranged on support 14, two ends and the outer cover 13 of worm screw 12 are rotationally connected, one end that worm screw 12 exposes outer cover 13 is fixedly connected with by flange 15 with coupling shaft 3, worm gear 11 engages with worm screw 12, worm gear 11 is fixedly mounted in installation shaft 16, installation shaft 16 and support 14 are rotationally connected.Select suitable ratio of gear; make rotational angle≤350 ° of Upper-lower Limit switch contact actuating arm installation shaft 16; and according to the angle of the limit with the protection point that transfinites; regulate the position of actuating arm in installation shaft 16, corresponding contact, reach the object that headstock gear moves to limit position and the shutdown of super spacing alarm.
In order to facilitate, see intuitively the data of gate height, display device 2 comprises display disc 21 and pointer 22, the end suit display disc 21 of installation shaft 16, the arranged outside of display disc 21 is fixedly connected on the pointer 22 of installation shaft 16 end, just on the outer cover 13 of display disc 21, there is opening, opening is provided with the transparent panel 23 being convenient to observed reading.
In order to play the effect of spacing alarm, over travel when preventing from opening and closing, the both ends of installation shaft 16 are all provided with collision block 4, and the upper and lower of collision block 4 all has the microswitch 5 for spacing alarm be arranged on support 14.
According to required keying elevation carrection scope and the installation site determined, the number of moving part of calculation code device 6, after electric-control system process, output detections precision is ± 1mm, and display resolution is the keying height value of 10mm.When rolling open and close machine operates; gate rises; the worm screw 12 that the rotating band of rolling open and close machine gear shaft is dynamically connected on it is rotated; to be engaged with worm screw 12 by worm gear 11 and slow down; the pointer 22 be fixedly connected in worm gear 11 installation shaft 16 makes coaxial rotation; thus gate lifting height can be read intuitively on display disc 21; when gate height rises to the highest; the collision block 4 be connected in installation shaft 16 will press microswitch 5; at this moment rolling open and close machine quits work, thus reaches the object that headstock gear runs to limit position and the shutdown of super spacing alarm.
With above-mentioned according to desirable embodiment of the present invention for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this invention technological thought, can carry out various change and amendment completely.The technical scope of this invention is not limited to the content on instructions, must determine its technical scope according to right.
