Further, rolling door is in the complete opening state during limit switch of said limited block above triggering it, and rolling door is in buttoned-up status during the limit switch of said limited block below triggering it.
Further; Said tensioned portion, limit switch are installed on the lateral surface of said rolling door doorframe; Also be provided with vertical hollow guide rail on the rolling door doorframe lateral surface; Have vertical chute on one side of the corresponding limit switch of said hollow guide rail, said limited block is provided with the T shape connecting portion that embeds in the said chute, and said fly rope is wire-wrapped in and drives described limited block on the T shape connecting portion and slide up and down along chute.
Further, described tensioned portion is the fixed pulley of being located on the rolling door doorframe.
Further, be shaped on screw thread on the said power transmission shaft, said fly rope solderless wrapped connection is in screw thread.Can not skid when adopting threaded power transmission shaft can guarantee the fly rope transmission.
Further, said limit switch is the travel switch of point contact type.
Further, said limit switch be induction type near switch.
Beneficial effect of the present invention: rolling door rotating shaft of the present invention drives limited block through power transmission shaft and fly rope and slides up and down; And the rising or the decline of rolling door are being controlled in the rolling door rotating shaft simultaneously; Power transmission shaft and rolling door spool have unequal angular velocity; But the linear velocity of rolling door spool is greater than power transmission shaft, and limited block and rolling door not only can synchronized movement, and rolling door complete opening or to close required time fully just in time identical with the coasting time of limited block between two limit switches; Thereby control mode of the present invention is more directly perceived, and Stroke Control is convenient, accurate; In addition, the installation of limit switch, limited block does not receive the restriction of rolling door structure, can be installed in the higher position of rolling door doorframe, with this influence that reduces extraneous factor, makes the more stable work of controlling organization reliable.
Description of drawings
Below in conjunction with accompanying drawing the present invention is further described:
Fig. 1 is the structural representation of electric rolling door of the present invention;
Fig. 2 is the structural representation of range controlling mechanism of the present invention;
Fig. 3 is the A-A sectional drawing among Fig. 2.
The specific embodiment
With reference to Fig. 1, shown in Figure 2; The present invention is a kind of range controlling mechanism of electric rolling door; Comprise rolling door doorframe 1, be located at the rolling door rotating shaft 11 at rolling door doorframe 1 top and drive the motor 10 of rolling door rotating shaft 11; Said rolling door rotating shaft 11 ends extend outward the power transmission shaft 2 of one section diameter less than rolling door rotating shaft 11, are wound with end to end fly rope 3 on the said power transmission shaft 2, and said power transmission shaft 2 belows are provided with the tensioned portion 4 that said fly rope 3 is tightened; Said fly rope 3 is provided with the limited block 7 with its interlock; On the straight-line trajectory of limited block 7, be provided with two relative limit switches 5, said limit switch 5 is electrically connected with the control circuit of motor 10, and the upper and lower displacement of said limited block 7 triggers the break-make of corresponding limit switch 5 control machine operation circuit.
Rolling door is in the complete opening state during limit switch 5 of limited block 7 above triggering it, and rolling door is in buttoned-up status during the limit switch 5 of said limited block 7 below triggering it; Described tensioned portion 4, limit switch 5 all are installed on the lateral surface of said rolling door doorframe; On rolling door doorframe lateral surface, also be provided with vertical hollow guide rail 6; As shown in Figure 3; Have vertical chute 61 on one side of said hollow guide rail 6 corresponding limit switches 5, said limited block 7 is provided with the T shape connecting portion 71 that embeds in the said chute 61, and said fly rope 3 is wire-wrapped in and drives described limited block 7 on the T shape connecting portion 71 and slide up and down along chute 61; Because of fly rope 3 limited block 7 easy shaking when driving limited block 7 and slide, have influence on and the contacting of limit switch 5, above-mentioned guide rail is set can makes limited block 7 interior orientation slides in the path of guide rail appointment, guarantee that limited block 7 can well contact with limit switch 5; Be shaped on screw thread on the power transmission shaft 2, said fly rope 3 solderless wrapped connections can not be skidded when adopting threaded power transmission shaft 2 can make fly rope 3 transmissions in screw thread; Described tensioned portion 4 is for being located at the fixed pulley on the rolling door doorframe.
Limit switch 5 of the present invention can adopt the travel switch of point contact type, and limited block 7 must contact with it and could trigger the control circuit that it breaks off motor 10; Perhaps adopt induction type near switch; Through approaching limited block 7 is carried out perception; To break off the control circuit of motor 10, the characteristics that have reliable operation, long, low in energy consumption, multiple positioning accuracy of life-span is high, operating frequency is high and adapts to bad working environment.
During practical application; The rolling door rotating shaft drives the limited block upstream or downstream through power transmission shaft and fly rope; And the rising or the decline of rolling door are being controlled simultaneously in the rolling door rotating shaft, and power transmission shaft is extended by the rolling door rotating shaft, thereby power transmission shaft and rolling door spool have unequal angular velocity; The power transmission shaft diameter is less than the rolling door rotating shaft; Thereby the linear velocity of rolling door spool is greater than power transmission shaft, and limited block and rolling door not only can synchronized movement, and rolling door complete opening or to close required time fully just in time identical with the coasting time of limited block between two limit switches; Rolling door is in the complete opening state when that is to say the limit switch of limited block above triggering it, and rolling door is in buttoned-up status during the limit switch of said limited block below triggering it; For traditional control mode and tube shaped electric machine, control mode of the present invention is more directly perceived, and Stroke Control is convenient, accurate; In addition, the installation of limit switch, limited block does not receive the restriction of rolling door structure, can be installed in the higher position of rolling door doorframe, with this influence that reduces extraneous factor, makes the more stable work of controlling organization reliable.
