Description of drawings
Fig. 1 is the structural representation of the embodiment of the invention;
Fig. 2 is the upward view of Fig. 1;
Fig. 3 is the right elevation of Fig. 1.
The specific embodiment
As Fig. 1, Fig. 2 and shown in Figure 3, a kind of single-phase electric gourd with lower bound range stop, include housing 1, place housing 1 inboard reel 2, retarder 3, drive reel 2 motor rotating 4, operating element 5, be wound in steel rope 6, upper limit device 7, lower caging device 8 and range limiter 9 on the reel 2.Described lower caging device 8 includes micro-switch 81, micro-switch slippery fellow 82, action transmits 83, the guide rod 84 that cooperates control motor 4 to rotate with the micro-switch assembly, spring 85, described guide rod 84 1 ends place the respective side of range limiter 9, and extend near memory cam 91 corresponding positions, 2 liang of dividing plate 21 corresponding positions of interlude and reel extend near between reel two dividing plates 21, the other end and action are transmitted 83 and are in transmission connection, here need to prove that guide rod 84 and action transmit the relation of being in transmission connection of 83, guide rod 84 can transmit 83 with action captives joint, also can be flexible connection, described captive joint can transmit 83 with guide rod 84 and action by the mode of screw or riveted joint or welding and be connected, described flexible connection is meant after 83 pivot bush unit is transmitted in guide rod 84 and action and tightens up by screw, described these be the technical scheme that is equal to all with the present invention; Described range limiter 9 is arranged on the outside of housing 1 end wall 11, comprise memory cam 91, reduction gearing mechanism between input shaft 92 and memory cam 91 and the input shaft 92, described reduction gearing mechanism is by sun wheel 93, planetary wheel carrier 94, planet wheel spindle 95, satellite gear 96, moving inner gear 97, quiet inner gear 98 constitutes, sun wheel 93 is captiveed joint with input shaft 92, input shaft 92 is captiveed joint with drum shaft 22, satellite gear 96 is arranged on sun wheel 93 peripheries, and with sun wheel 93 engagement, moving inner gear 97 and quiet inner gear 98 are arranged on the periphery of satellite gear 96, it is poor that moving inner gear 97 and quiet inner gear 98 have tooth, and mesh with satellite gear 96 respectively, transmitting ratio is wound in number of total coils on the reel 2 greater than steel rope 6, in embodiments of the present invention, the number of the satellite gear 96 that is provided with is two, moving inner gear 97 is 2 with the tooth difference of quiet inner gear 98, and memory cam 91 is fixedly installed on moving inner gear 97 outer rings, and memory cam 91 can be regulated arbitrarily with the circumference relative position of moving inner gear 97; In embodiments of the present invention, described guide rod 84 pivot bush units also axially are fixed on the body of retarder 3 by the elastic compression of spring 85, make it to have only a rotational freedom, described action is transmitted 83 and is provided with slope 831 with micro-switch slippery fellow 82 sides that contact, this slope 831 cooperates with micro-switch foxy 82, the unlatching and the closure of control micro-switch 81, this action main effect of 83 of transmitting is in order to touch and compress micro-switch slippery fellow 82, so action is transmitted on 83 and not only is confined to be provided with slope 831, setting thereon compresses projection and also can reach same effect, can be used as a technical scheme that is equal to the present invention; Described micro-switch 81 is installed in the connection box 10, and setting not only has the effect of protection switch like this, and attractive in appearance.Said apparatus is provided with lower caging device 8 and range limiter 9 with single-phase electric gourd, like this benefit of She Zhiing be actv. disappear except when single-phase electric gourd when dropping to nadir because of not stopping immediately, and make steel rope 6 reversing senses on reel 2, the potential safety hazard that causes weight to rise once more or cause the upper limit device 7 of single-phase electric gourd to damage or cause weight to fall inadequately because of the power that tightens up of steel rope 6 ends; Can increase substantially the safety of operation coefficient of single-phase electric gourd by said apparatus.
Concrete principle of work of the present invention is: the position that at first must regulate lower limit, the decline button of promptly operating operating element 5 makes single-phase electric gourd descend gradually from eminence, steel rope 6 progressively winds from reel 2, when steel rope 6 drops to the lower-limit point of wanting, regulate the circumferential position of memory cam 91 on moving inner gear 97 when for example making steel rope 6 on reel 2, keep 3 circles, make memory cam 91 guide rod 84 of just conflicting, lower caging device 8 works, the other end of guide rod 84 just can order about action and transmit 83 rotation, promote micro-switch slippery fellow 82 and make micro-switch 81 actions, single-phase electric gourd can not continue to descend when at this moment operating the decline button of operating element 5, and can only operate the rising button of operating element 5, at this moment drum shaft 22 is rotated, drive the input shaft 92 of captiveing joint with drum shaft 22, the sun wheel 93 of captiveing joint with input shaft 92 is rotated, pass to satellite gear 96, satellite gear 96 is at planetary wheel carrier 94, planet wheel spindle 95, under the effect of quiet inner gear 98, circumference rotates to make inner gear 97 do at a slow speed, remember cam 91 simultaneously and also break away from guide rod 84 at a slow speed, so just the straight-line displacement with steel rope 6 has changed into the angular transposition of memory cam 91, when steel rope 6 rises to the optional position and stops, the decline button of operating operating element 5 again descends steel rope 6 gradually, at this moment drum shaft 22 backward rotation, drive the input shaft 92 of captiveing joint with drum shaft 22, make sun wheel 93 backward rotation of captiveing joint with input shaft 92, pass to satellite gear 96, satellite gear 96 is at planetary wheel carrier 94, planet wheel spindle 95, under the effect of quiet inner gear 98, making inner gear 97 do the slow reverse circumference rotates, remember cam 91 simultaneously also at a slow speed near guide rod 84, reducing to the lower position that at first regulates up to steel rope 6 is that steel rope 6 kept for 3 whens circle on reel 2, memory cam 91 guide rod 84 of just conflicting, lower caging device 8 works, the other end of guide rod 84 just can order about action and transmit 83 rotation, promote micro-switch slippery fellow 82 and make micro-switch 81 actions, thereby single-phase electric gourd can not continue to descend and plays the effect of lower limit when at this moment operating the decline button of operating element 5.
