during concrete enforcement, described support is fixed with screw rod, described brake arm can be set on described screw rod movably, this screw rod is also arranged with can the first switch bracket of movement, this first switch bracket is equipped with described first feedback switch, be provided with between the side of this first switch bracket and described brake arm and this brake arm elastic-restoring force can be provided to make this brake arm be in the elastic component of closure state, the relative opposite side of described first switch bracket has kept out setting nut, this setting nut screw thread fit is on described screw rod, described brake arm is fixed with and can be pushed to make described brake arm be in the push rod of open mode under the electromagnetic action of the electromagnet of towing machine, the shell of described electromagnet or described support are equipped with second switch support, this second switch support is equipped with described second feedback switch.
described elastic component adopts spring, and this spring is set on described screw rod compressively.
preferably, described brake arm has a pair, accordingly, described first switch bracket, described first feedback switch, described second switch support, described second feedback switch, described push rod, described elastic component, described setting nut also have a pair respectively, and brake arm described in a pair is set in the two ends of described screw rod respectively.
further, in described electromagnet, there is the coil that two independently-powered, respectively with the push rod phase electrical cooperation in brake arm described in a pair.
due to the utilization of technique scheme, the present invention compared with prior art has following advantages: in the real-time detection structure of this brake arm position, when brake arm is in open mode, detects by the first feedback switch; When brake arm is in closure state, detect by the second feedback switch; When brake arm be in not only do not open but also not closed state time, brake arm does not touch the first feedback switch and the second feedback switch, now by elevator controlling mainboard, this first feedback switch and the second feedback switch forbid that elevator runs, and effectively prevent the generation that elevator causes the accident because of the fault of braking.
Detailed description of the invention
structure of the present invention is set forth further below in conjunction with accompanying drawing.
shown in Figure 1, the real-time detection structure of brake arm position on elevator traction machine, comprise engine base of traction machine 1, be arranged on a pair brake arm 2 on support 1, elevator controlling mainboard (not shown) rotationally, be all connected electrically in a pair first feedback switch 5 on elevator controlling mainboard and a pair second feedback switch 6, a pair brake arm 2 is oppositely arranged, for holding braking traction sheave tightly.Each brake arm 2 all has open mode and closure state, and opening of brake arm 2 is realized by the electromagnet 8 of towing machine and the electrical cooperation of push rod 9, and the closed of brake arm 2 is realized by elastic component 3.In FIG, elastic component 3 adopts spring, this spring is set on screw rod 10 compressively, screw rod 10 is fixed on engine base of traction machine 1, a pair brake arm 2 can be set in the two ends of screw rod 10 respectively movably, a pair brake arm 2 is all fixed with push rod 9, can be pushed at the electromagnetic action lower push-rod 9 of the electromagnet 8 of towing machine, make brake arm 2 be in open mode.There is the coil that two independently-powered in electromagnet 8, respectively with the push rod 9 phase electrical cooperation in a pair brake arm 2, promote the action of two push rods 9 independently.In FIG, the two ends of screw rod 10 are arranged with respectively can first switch bracket 4 of movement, first feedback switch 5 each first switch bracket 4 is equipped with, elastic component 3 is provided with between the side of each first switch bracket 4 and corresponding brake arm 2, namely the spring compressed, for providing brake arm 2 elastic-restoring force.To the coil power supply in electromagnet 8, be then pushed at the electromagnetic action lower push-rod 9 of electromagnet 8, make brake arm 2 be in open mode; After coil blackout, the electromagnetic action of electromagnet 8 disappears, then under the elastic-restoring force effect of elastic component 3, brake arm 2 is in closure state, namely holds braking traction sheave tightly.The relative opposite side of each first switch bracket 4 has all kept out setting nut 11, and this setting nut 11 screw thread fit, on screw rod 10, turns setting nut 11, can the compressive force of regulating spring, thus regulates the braking force of brake arm 2 pairs of traction sheaves.The shell of electromagnet 8 or support 1 are equipped with second switch support 7, this second switch support 7 are equipped with the second feedback switch 6.
in FIG, be energized to electromagnet 8, then push rod 9 is pushed outwards dynamic, brake arm 2 is made to be in open mode, brake arm 2 touches the first feedback switch 5, has distance, namely do not touch the second feedback switch 6 between this brake arm 2 and second feedback switch 6, first feedback switch 5, second feedback switch 6 all accesses elevator controlling mainboard, then elevator controlling mainboard can detect the open mode of brake arm 2 by the first feedback switch 5; After giving electromagnet 8 power-off, under the elastic-restoring force effect of elastic component 3, brake arm 2 is pushed inwardly together with push rod 9, brake arm 2 is made to be in closure state, brake arm 2 touches the second feedback switch 6, have distance between brake arm 2 and the first feedback switch 5, namely do not touch the first feedback switch 5, elevator controlling mainboard can detect the closure state of brake arm 2 by the second feedback switch 6; When due to fault, brake arm 2 is entered if any foreign matter, brake arm 2 is made both not to be in open mode when not also being in closure state, all distance is had between brake arm 2 and the first feedback switch 5 and the second feedback switch 6, namely this brake arm 2 does not all touch the first feedback switch 5 and the second feedback switch 6, now by elevator controlling mainboard, this first feedback switch 5 and the second feedback switch 6 forbid that elevator runs, 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 structure of this brake arm position, by arranging the first feedback switch and the second feedback switch, detecting the opening of brake arm, closure state and both not opened also not closed faulty condition, eliminating the potential safety hazard that elevator exists because of braking system faults.Furthermore, the function that the real-time detection structure of this brake arm position can also be made to have guarantee that the mode of operation of brake arm is correct, as when making brake arm open to electromagnet energising, must guarantee that brake arm is correctly opened, first feedback switch is touched by brake arm, second feedback switch is not touched, closed also like this.In FIG, by turning setting nut 11, the braking force of brake arm 2 pairs of traction sheaves can not only be regulated, the position of the first switch bracket 4 can also be regulated, can action to realize when brake arm 2 is opened the first feedback switch 5, the second feedback switch 6 can the action when brake arm 2 closes.
