The utility model further is set to: described guide rod pivot bush unit also is axially fixed on the body of retarder, make it to have only a rotational freedom, described action is transmitted head and is provided with the slope with the foxy side that contacts of micro-switch, this slope cooperates with micro-switch is foxy, being provided with like this makes guide rod be subjected to the collision of steel rope, thereby drive action and transmit head, impel the unlatching and the closure of micro-switch.
Below in conjunction with accompanying drawing the utility model is further described:
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the A-A cutaway view of Fig. 1;
Fig. 3 is the canoe scheme drawing of reel and steel rope among the utility model embodiment.
The specific embodiment
As shown in Figure 1 and Figure 2, a kind of suspension transferring machine includes 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 and lower caging device 8 on the reel 2; Described lower caging device 8 includes micro-switch 81, micro-switch slippery fellow 82, action and transmits 83 and cooperates the guide rod 84 of controlling motor 4 rotations with the micro-switch assembly, guide rod 84 places an end of reel 2 to extend to reel dividing plate 21 corresponding positions at the close housing 1 end wall place of reel 2, and the other end of guide rod 84 transmits 83 flexible connection with action; Described reel 2 correct positions are provided with a through hole 22, and steel rope 6 passes this through hole 22, and twine 1 to 5 again and enclose on reel 2, the fixing end of steel rope 6 then, as shown in Figure 3; Described motor 4 is that magnetic brake formula asynchronous dynamo is close in single-phase two-capacitance capacitive running, utilizes the running of higher value capacitor start when suspension transferring machine promotes weight, utilizes the running of smaller value capacitor start when transferring weight, has improved the work system of motor relatively.Said apparatus is provided with lower caging device 8 with suspension transferring machine, like this benefit of She Zhiing be actv. disappear except when suspension transferring machine 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 suspension transferring machine to damage; Reel 2 correct positions are provided with a through hole 22, also keep 1 to 5 after the steel rope 6 when making suspension transferring machine transfer weight on the reel 2 drains and enclose on reel 2, the potential safety hazard of having avoided the power that tightens up because of steel rope 6 ends to cause weight to fall inadequately; Can increase substantially the safety of operation coefficient of suspension transferring machine by said apparatus.
In the utility model embodiment, described guide rod 84 pivot bush units also are axially fixed on the body of retarder 3, 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, when suspension transferring machine is transferring that the steel rope on the reel 26 reduces as far as possible in the weight process, reel 2 is subjected to the propulsive effort of motor 4 can not stop rotation, thereby cause steel rope 6 from another direction revolution, the time conflict in revolution and to be located at an end of the other guide rod 84 of reel 2, the collision that guide rod 84 is subjected to steel rope 6 rotates, thereby guide rod 84 drives action and transmits 83, make it to rotate, micro-switch slippery fellow 82 just can transmit under the promotion on 83 slope 831 to micro-switch 81 sliding going in action, makes micro-switch 81 actions, motor 4 shuts down immediately, thereby plays the effect of lower limit.
