Fig. 1 is a structural representation of the present invention.
Fig. 2 is that the K on drum wheels edge is to view.
Fig. 3 is the partial enlarged drawing of frictional disk and ring flange connected mode in the friction electromagnetic clutch.
Specific implementation
As shown in Figure 1, the middle part of reducing rotating shaft 5 is installed with reel 4, and fixing by nut 6.The right-hand member of rotating shaft 5 connects the friction electromagnetic clutch.Be fixed with drive unit 20 on fixed mount 11, this drive unit can be a motor, also can be the form that motor combines with decelerator, and its output shaft is connected on the another side of friction electromagnetic clutch.The friction electromagnetic clutch reaches the frictional disk 25 that joins with ring flange elasticity by electromagnet 1, clutch rotating disk 27, ring flange 3 and forms.Clutch rotating disk 27 connects the form of card for axle sleeve, and its axle sleeve is in order to connect driving shaft, and its card is in order to connect magnetism-isolating loop 26 and friction plate 2, and friction plate is relative with frictional disk 25.Ring flange 3 also connects the form of card for axle sleeve, its axle sleeve is in order to connect rotating shaft 5, and its card is in order to fixedly connected frictional disk 25.Ring flange 3 with a kind of connected mode of frictional disk 25 is, between ring flange 3 and the frictional disk 25 spring leaf 24 arranged, and rivet 23 is riveted on spring leaf 24 respectively on ring flange 3 and the frictional disk 25 (as shown in Figure 3).Frictional disk 25 has certain interval with clutch rotating disk 27, when electromagnet 1 energising, because magnetism-isolating loop 26 has cut off the magnetism guiding access of clutch rotating disk 27 card edges and middle part axle sleeve, force the magnetic line of force to walk around frictional disk 25 and form magnetic loop, thus frictional disk 25 is inhaled to clutch rotating disk 27.Under the frictional resistance of friction plate 2 and frictional disk 25 drives, make ring flange 3 and rotating shaft 5 rotations.The suction-combining force of frictional disk 25 and clutch rotating disk 27 has been determined the size of the lifting force of the safety rope of winding on reel 4 thus by the number of turn decision of solenoid in the electromagnet 1.So the coil in the electromagnet 1 preferably has more than two groups, so that regulate.When electromagnet 1 outage, spring leaf 24 restores, and with frictional disk 25 ring flange 3 one sides of pulling back, makes it to disengage with clutch rotating disk 27.
On the ring flange 3 of friction electromagnetic clutch, also be connected to sensor stand 10,, form the reel rotation direction sensor, to detect the rotating situation of reel 4 in order to infrared sensor to be installed.Rotating shaft 5 two ends in reel 4 both sides are socketed with bearing 13 and bearing bracket stand 12 respectively, promptly by support and bearing stable support rotating shaft 5, make rotating shaft 5 and reel 4 smooth operations.
The brake that connects at rotating shaft 5 left ends can be existing all kinds of shaft brakes such as external contracting brake, and for simplifying and cramped construction, the present invention has adopted a kind of friction-disc electromagnetic brake.Its structure is made up of electromagnet 8, ring flange 7 and frictional disk 9 as shown in Figure 1, and spring leaf 16 is arranged between ring flange and the frictional disk, and rivet 14 is riveted on spring leaf 16 respectively on ring flange 7 and the frictional disk 9.Electromagnet 8 is fixing by fixed mount 15, between frictional disk 9 and the electromagnet 8 certain interval is arranged, and ring flange 7 rotates with rotating shaft 5 with frictional disk 9.When this brake regulated brake, electromagnet 8 electric adhesive, with the frictional disk 9 that rotates tightly adhesive on fixing electromagnet 8, the pulling force of safety rope when its adhesive brake force should be greater than single tenesmus, thereby the purpose that reaches braking, protects.The use of friction-disc electromagnetic brake; can realize reel and rotating shaft under normal conditions normal rotation and the brake hard of training when unexpected appears; and the structure that makes brake has reached simple and direct, compact; dwindled the overall volume of this protective device; reduce manufacturing cost, and overcome the translation relatively of traditional electrical magnetic brake, technological deficiency in relative rotation.
Among Fig. 1, the electromagnetic brake that plays the auxiliary braking protective effect is a kind of common towed electromagnet, is made up of electromagnet 22 and armature 21, and a wheel that is positioned at reel 4 is along the outside.Have unidirectional draw-in groove (shown in Figure 2) on this drum wheels edge, the dop on the armature 21 can snap in this unidirectional draw-in groove.The electromagnet 22 of electromagnetic brake is fixed on the location-plate 17, and the front end of spring 18 passes location-plate, joins with the armature 21 of electromagnetic brake, and the rear end support and connection of spring 18 are on fixed mount 19.In the moment that the energising of this device starts, electromagnet 22 is also switched on, and with armature 21 adhesives, the spring 18 that joins with armature is compressed, and the dop on the armature withdraws from drum wheels along last unidirectional draw-in groove simultaneously, and reel 4 is run well.When this electromagnetic brake regulated brake, electromagnet 22 dead electricity, armature 21 protracts under the elastic force effect of spring 18, make dop withstand the wheel edge of reel 4, along between the process that turns around, dop can snap in wheel automatically along in the last unidirectional draw-in groove, and reel 4 is thoroughly braked at wheel.
The course of work of this device is, presses start button, and forward rotation is made in motor 20 energisings, the electromagnetic clutch that rubs simultaneously energising, and clutch rotating disk 27 and frictional disk 25 adhesives, thus drive reel 4 forward rotation, the safety rope that twines on it is risen.This moment, electromagnetic brake was also finished the work of energising withdrawal armature dop, and the friction-disc electromagnetic brake is finished the work that outage discharges frictional disk 9, makes device present no lock attitude.Because trainer's the speed of climbing is all less than hoisting velocity, so safety rope keeps lifting state constantly, the friction electromagnetic clutch then is the operation that throws switch.Accidentally drop or step on sky and when falling if any the trainer, reel 4 reversings, the reel rotation direction sensor sends signal to control circuit, and the control circuit action makes friction-disc electromagnetic brake energising braking, auxiliary selenoid brake power-off brake.If the friction-disc electromagnetic brake breaks down or installs whole outage, then Fu Zhu electromagnetic brake is owing to be the outage action, so still can rely on the elastic force of spring 18, make the armature dop snap in drum wheels smoothly, can prevent thus because of the unsafe factor that has a power failure or the fault of device own is caused along in the last unidirectional draw-in groove.When the trainer need drop to ground halfway, by the action button instruction, remove double brake, drive unit 20 is able to backward rotation, the trainer slowly can be settled out.
The control circuit of this device can be made up of single-chip microcomputer and conventional control element overlap joint, to realize above-mentioned control function.Also can utilize single-chip microcomputer and counter etc. simultaneously, each training achievement of every trainer be added up printed.Because this statistical report mode has stronger objectivity and accuracy, thereby helps promoting the trainer, improve training achievement.
