The specific meaning of the above terms in the present application will be understood in specific cases by those of ordinary skill in the art.
As shown in fig. 1, 2 and 3, an embodiment of the present application provides a belt breakage detection mechanism, which includes an upper mounting arm 101 and an upper connection structure 102. The upper mounting arm 101 is fixed in position, and the upper connection structure 102 can move relative to the upper mounting arm 101, so that the upper connection structure 102 is kept away from the belt breakage detection switch 104 when the magnetic scale 103 is operating normally. When the magnetic grid ruler 103 breaks, the upper connecting structure 102 moves, and the broken belt detection switch 104 can be triggered in the moving process of the upper connecting structure 102, so that the protection mechanism of the elevator is started.
As shown in fig. 4, in the elevator, since the magnetic grating ruler 103 is generally vertically disposed, the upper connection structure 102 is connected to the magnetic grating ruler 103 at the top end of the magnetic grating ruler 103, so as to ensure that the upper connection structure 102 can trigger the belt breakage detection switch 104, and the belt breakage detection switch 104 is disposed above the upper connection structure 102. Further, the upper connection structure 102 can move upward when the magnetic grid ruler 103 breaks, so that the broken belt detection switch 104 is triggered in a striking manner.
The broken belt detection mechanism further comprises a controller, the controller is electrically connected with the broken belt detection switch 104, when the broken belt detection switch 104 is triggered, the broken belt detection switch 104 sends corresponding electric signals to the controller, and the controller starts a protection mechanism of the elevator to avoid elevator faults.
Specifically, in order to make the upper connection structure 102 move upwards against its own weight, an elastic structure 201 is disposed between the upper connection structure 102 and the upper mounting arm 101, i.e. one end of the elastic structure 201 abuts against the upper mounting arm 101, and the other end abuts against the upper connection structure 102. The elastic structure 201 is always in a compressed state when the magnetic grid ruler 103 works normally, stores elastic potential energy, and when the magnetic grid ruler 103 breaks, the elastic structure 201 stretches and converts the stored elastic potential energy into kinetic energy of the upper connecting structure 102, so that the broken belt detection switch 104 is triggered. Specifically, the elastic structure 201 employs a spring.
In some examples, the upper attachment structure 102 is external to the upper mounting arm 101 and a guide structure is additionally provided to ensure that the upper attachment structure 102 can move in a vertical direction to accurately trigger the belt break detection switch 104.
Or the upper attachment structure 102 is slidably coupled to the upper mounting arm 101. The upper mounting arm 101 is provided with a first hollow structure, the shape of the first hollow structure corresponds to the cross-sectional shape of the upper connecting structure 102, and the upper connecting structure 102 is inserted into the upper mounting arm 101 to form sliding connection.
The horizontal positioning of the upper connecting structure 102 is limited by the upper mounting support arm 101, so that the horizontal shaking is avoided, and the upper connecting structure 102 moves smoothly in the vertical direction without being limited by the upper mounting support arm 101. It can be understood that the horizontal position adjustment of the upper connecting structure 102 depends on the movement of the upper mounting arm 101, the upper mounting arm 101 adopts a U-shaped structure, and the two parallel parts of the upper mounting arm 101 are all provided with a first hollow structure.
In some examples, the upper connection structure 102 includes a first mounting portion 203, a working portion 202, the first mounting portion 203 being angled with respect to the working portion 202, in particular, the first mounting portion 203 being approximately perpendicular to the working portion 202. The first installation part 203 is inserted into the first hollow structure, the first installation part 203 guides the movement of the upper connection structure 102 under the limit of the edge of the first hollow structure, the first installation part 203 is connected with the magnetic grid ruler 103, and the working part 202 is used for abutting and extruding the elastic structure 201.
It can be understood that, when the magnetic grating ruler 103 works normally, the magnetic grating ruler 103 provides downward traction force for the upper connecting structure 102, and under the guiding action of the first mounting portion 203 and the first hollow structure, the upper connecting structure 102 presses the elastic structure 201 through the working portion 202, so that the working portion 202 is far away from the broken belt detecting switch 104.
In some examples, the upper connection structure 102 is provided with a trigger 204, the trigger 204 being capable of triggering the belt break detection switch 104, while the trigger 204 is also capable of guiding the elastic structure 201. The trigger portion 204 is disposed on the working portion 202, a first end of the trigger portion 204 extends toward the direction of the belt breakage detection switch 104, and a second end of the trigger portion 204 extends toward the direction of the mounting arm 101, so that the elastic structure 201 can be sleeved on the second end of the trigger portion 204.
Specifically, the first hollow structure on the upper mounting arm 101 includes a portion having approximately the same cross-sectional shape as the trigger portion 204, and the trigger portion 204 can be inserted into the first hollow structure, thereby forming a sliding connection with the upper mounting arm 101. The magnetic scale 103 provides traction to the upper connection structure 102 through the connection with the upper connection structure 102, thereby controlling the compression degree of the elastic structure 201.
As shown in fig. 5, in some examples, the belt break detection mechanism further includes a lower mounting arm 301, a lower attachment structure 302. It can be understood that the lower connection structure 302 is located below the upper connection structure 102, and the lower connection structure 302 is connected with the lower end of the magnetic grating ruler 103, that is, the upper connection structure 102, the magnetic grating ruler 103 and the lower connection structure 302 form a sequentially connected whole, and in the case that the lower connection structure 302 is located in the vertical direction, the vertical direction position of the upper connection structure 102 is also fixed, and accordingly, the compression degree of the elastic structure 201 is fixed.
Further, the position of the lower connecting structure 302 is defined by the lower mounting support arm 301, and when the magnetic grating ruler 103 works normally, the lower connecting structure 302 is clamped with the lower mounting support arm 301, so that the integral upward movement formed by the upper connecting structure 102, the magnetic grating ruler 103 and the lower connecting structure 302 is avoided, and the false triggering of the broken belt detection switch 104 is caused.
Specifically, the lower mounting arm 301 is provided with a second hollow structure, and the lower connecting structure 302 is inserted into the second hollow structure, thereby forming a sliding connection. Wherein, because the shape of the second hollow structure corresponds to the cross-sectional shape of the lower connecting structure 302, the horizontal shaking of the lower connecting structure 302 is prevented, and the stability is improved.
In some examples, the lower connection structure 302 includes a bend 303, a second mount 304. The bending portion 303 is angled with respect to the second mounting portion 304, wherein the bending portion 303 is approximately perpendicular to the second mounting portion 304. The second installation part 304 inserts in the second hollow structure, guarantees sliding connection, and second installation part 304 is connected with magnetic grating chi 103, and kink 303 joint is at the edge of second hollow structure in the bottom of lower connection structure 302, avoids lower connection structure 302 to upwards remove, but does not restrict lower connection structure 302 to drop in lower installation support arm 301.
Specifically, the lower mounting arm 301 adopts a U-shaped structure, and two parallel parts of the lower mounting arm 301 are respectively provided with a second hollow structure.
Normally, the upper mounting arm 101 and the lower mounting arm 301 are fixed on the guide rail through guide rail press codes, so that the positions of the upper mounting arm 101 and the lower mounting arm 301 for mounting the magnetic grid ruler 103 are corresponding in the horizontal direction on the basis of neglecting the errors of the guide rail, and basically no adjustment is needed. In the case of special needs for adjustment, this can be achieved by simply adding or subtracting shims.
In some examples, to fix the magnetic grating ruler 103 to the upper connection structure 102 and the lower connection structure 302, a plurality of connection holes 401 are provided on each of the upper connection structure 102 and the lower connection structure 302, and the top ends of the magnetic grating ruler 103 are sequentially inserted into the connection holes 401 of the upper connection structure 102 from two sides of the upper connection structure 102. When the uppermost connection hole 401 is inserted, the magnetic scale 103 is fixed to the upper connection structure 102 by bending and then folding back to the middle of the magnetic scale 103 along the insertion path.
Similarly, the bottom ends of the magnetic grating ruler 103 are sequentially inserted into the respective connection holes 401 of the lower connection structure 302 from both sides of the lower connection structure 302. When inserted into the lowermost connection hole 401, the magnetic scale 103 is bent and then folded back to the middle of the magnetic scale 103 along the insertion path, thereby fixing the magnetic scale 103 to the lower connection structure 302.
In some examples, the broken belt detection mechanism further includes a fastening structure 402, where the fastening structure 402 fastens the top end of the magnetic grating ruler 103 folded back in the middle and the bottom end of the magnetic grating ruler 103 to the middle of the magnetic grating ruler 103, so as to avoid the magnetic grating ruler 103 from separating from the upper connection structure 102 and the lower connection structure 302. Specifically, the fastening structure 402 adopts the ribbon, and the ribbon sets up two sets of ribbon, and two sets of ribbon correspond to the top and the bottom of magnetic grating chi 103 respectively, all exist in every group and are fixed the ribbon in the middle part of magnetic grating chi 103 with the top or the bottom of magnetic grating chi 103, also exist and are fixed the ribbon jointly with the top or the bottom of magnetic grating chi 103, magnetic grating chi 103 middle part, go up connection structure 102 or lower connection structure 302.
In some examples, the upper connection structure 102 is provided with pin holes 105, the arrangement of the pin holes 105 being capable of facilitating loading of the upper connection structure 102. Wherein the pin bore 105 is at the bottom of the upper mounting arm 101 when the resilient structure 201 is in a compressed state.
When the magnetic scale 103 is installed, the upper pressure connection structure 102 is pressed down, so that the elastic structure 201 is in a compressed state. After the pin hole 105 moves below the upper mounting arm 101, the pin is inserted into the pin hole 105 and engages the upper connecting structure 102, thereby maintaining the elastic structure 201 in a compressed state. After the magnetic grating ruler 103 is installed, the pin is removed to enable the magnetic grating ruler 103 to be in a tight state. Meanwhile, due to the use of the elastic structure 201, even if the magnetic scale 103 is stretched during use, it can be kept in a tight state.
