accompanying drawing 1 is schematic diagram of the present invention.
?
The specific embodiment
further set forth structure of the present invention below in conjunction with accompanying drawing.
shown in Figure 1, the real-time detection architecture of band-type brake arm position on elevator traction machine, comprise engine base of traction machine 1, be arranged on a pair of band-type brake arm 2 on support 1, elevator rotationally and control the mainboard (not shown), all be connected electrically in elevator and control a pair of the first feedback switch 5 and a pair of the second feedback switch 6 on mainboard, a pair of band-type brake arm 2 is oppositely arranged, for holding the braking traction sheave tightly.Each band-type brake arm 2 all has open mode and closure state, and opening of band-type brake arm 2 is to coordinate realization by the electromagnet 8 of towing machine and the electromagnetism of push rod 9, and the closure of band-type brake arm 2 realizes by elastic component 3.In Fig. 1, elastic component 3 adopts spring, this spring is set on screw rod 10 compressedly, screw rod 10 is fixed on engine base of traction machine 1, a pair of band-type brake arm 2 can be set in the two ends of screw rod 10 respectively movably, all be fixed with push rod 9 on a pair of band-type brake arm 2, can be pushed at the electromagnetic action lower push-rod 9 of the electromagnet 8 of towing machine, make band-type brake arm 2 in open mode.Two independently-powered coils are arranged in electromagnet 8, coordinate with the push rod 9 phase electromagnetism on a pair of band-type brake arm 2 respectively, promote independently 9 actions of two push rods.In Fig. 1, be arranged with respectively first switch bracket 4 that can move on the two ends of screw rod 10, first feedback switch 5 is housed on each first switch bracket 4, be provided with elastic component 3 between one side of each the first switch bracket 4 and corresponding band-type brake arm 2, the spring compressed, for providing the band-type brake arm 2 elastic-restoring forces.Give the coil power supply in electromagnet 8, the electromagnetic action lower push-rod 9 at electromagnet 8 is pushed, and makes band-type brake arm 2 in open mode; After coil blackout, the electromagnetic action of electromagnet 8 disappears, and, under the elastic-restoring force effect of elastic component 3, band-type brake arm 2, in closure state, is held the braking traction sheave tightly.All kept out setting nut 11 on the relative opposite side of each the first switch bracket 4, these setting nut 11 screws thread fit, on screw rod 10, turn setting nut 11, compressive force that can regulating spring, thus regulate the braking force of 2 pairs of traction sheaves of band-type brake arm.On the shell of electromagnet 8 or support 1, second switch support 7 is housed, the second feedback switch 6 is housed on this second switch support 7.
in Fig. 1, give electromagnet 8 energisings, push rod 9 is pushed outwards moving, make band-type brake arm 2 in open mode, band-type brake arm 2 touches the first feedback switch 5, between this band-type brake arm 2 and the second feedback switch 6, distance is arranged, and does not touch the second feedback switch 6, the first feedback switch 5, the second feedback switch 6 all access elevator and control mainboard, and elevator is controlled mainboard and the open mode of band-type brake arm 2 can be detected by the first feedback switch 5; After giving electromagnet 8 outages, under the elastic-restoring force effect of elastic component 3, band-type brake arm 2 is inwardly promoted together with push rod 9, make band-type brake arm 2 in closure state, band-type brake arm 2 touches the second feedback switch 6, between band-type brake arm 2 and the first feedback switch 5, distance is arranged, do not touch the first feedback switch 5, elevator is controlled mainboard can detect the closure state of band-type brake arm 2 by the second feedback switch 6; When due to fault, enter band-type brake arm 2 if any foreign matter, make band-type brake arm 2 both not in open mode during also not in closure state, between band-type brake arm 2 and the first feedback switch 5 and the second feedback switch 6, distance is all arranged, this band-type brake arm 2 does not all touch the first feedback switch 5 and the second feedback switch 6, now this first feedback switch 5 and the second feedback switch 6 are controlled mainboard by elevator and are forbidden elevator operation, and report an error, and prevent the generation that elevator causes the accident because of the fault of braking.
to sum up, in the real-time detection architecture of this band-type brake arm position, by the first feedback switch and the second feedback switch are set, detect the opening of band-type brake arm, closure state and both do not opened also not closed faulty condition, eliminate the potential safety hazard that elevator exists because of the brake system fault.Furthermore, can also make the real-time detection architecture of this band-type brake arm position there is the correct function of mode of operation of guaranteeing the band-type brake arm, as when to electromagnet, energising makes the band-type brake arm open, must guarantee that the band-type brake arm correctly opens, the first feedback switch is touched by the band-type brake arm, the second feedback switch is not touched, and closure is also like this.In Fig. 1, by turning setting nut 11, can not only regulate the braking force of 2 pairs of traction sheaves of band-type brake arm, can also regulate the position of the first switch bracket 4, the first feedback switch 5 can move when realizing that band-type brake arm 2 is opened, and the second feedback switch 6 can action when band-type brake arm 2 is closed.
