Detailed Description
The technical solution of the present invention will be described in detail by the following specific examples.
As shown in fig. 1, the elevator flat bed anti-induction disappearance device comprises a plurality of baffle plates 5 arranged at intervals according to floors, a first inductor 6 and a second inductor 7, wherein the flat bed inductor is provided with a U-shaped notch, any baffle plate 5 is installed on an elevator car guide rail through a baffle plate support 4, the first inductor 6 and the second inductor 7 are installed on the inductor support through an inductor installation seat 3, and when the elevator is in a flat bed, the baffle plates 5 are positioned in the notches of the flat bed inductors. The inductor support comprises an adjusting plate 8, an inductor mounting seat 3, an inductor fixing frame 2 and an inductor fixing plate 1, the inductor fixing frame is mounted on the side face of the car frame upright post, a plurality of long round holes are formed in the inductor adjusting plate 8, and the flat inductor is connected to the long round holes through bolts. Inductor mount pad 3 swing joint is on inductor mount 2, and inductor fixed plate 1 is including consecutive inductor regulating plate 8, inductor mount pad 3, inductor mount 2 and inductor 6 and 7. In this embodiment, the inductor bracket is provided with a first planar inductor 6 and a second planar inductor 7, the distance between the first planar inductor 6 and the second planar inductor 7 is smaller than the length of the magnetic shield, and the length of the magnetic shield 5 can simultaneously cover the two planar inductors.
The elevator flat bed induction device has the working principle as follows:
the first sensor 6 and the second sensor 7 set the following logic program. The first inductor 6 is blocked by the magnetic-blocking plate 5 to generate a blocking signal A, and the control cabinet controls the second inductor 7 to be invalid; the first inductor 6 is not blocked by the magnetic-isolating plate 5 to generate a blocking signal A, and the control cabinet controls the second inductor 7 to become effective. Similarly, the second inductor 7 is blocked by the magnetic-blocking plate 5 to generate a blocking signal B, and the control cabinet controls the first inductor 6 to be invalid; the second inductor 7 is not blocked by the magnetic-isolating plate 5 to generate a blocking signal B, and the control cabinet controls the first inductor 6 to become effective. The control cabinet receives the blocking signal A or the blocking signal B to control the elevator to be flat, and the elevator does not receive the blocking signal A or the blocking signal B to control the elevator to run.
The action process is as follows:
after the elevator installation finishes, when the elevator down operates from last, when magnetic shield 5 went to first inductor 6, as shown in fig. 3, first inductor 6 sent separation signal A to the switch board, and the flat bed of switch board control elevator, and 7 response effects of switch board control second inductor are closed simultaneously. The magnetic isolation plate 5 continues to descend, the magnetic isolation plate 5 simultaneously isolates the first inductor 6, the second inductor 7 and the signals received by the control cabinet, if the signals are the isolation signals A, the elevator continues to level, and the method is shown in figure 4; when the elevator continues to move downwards, the magnetic isolation plate 5 is separated from the first inductor 6 and not separated from the second inductor 7, as shown in fig. 5, the first inductor 6 does not send a blocking signal a, the control cabinet does not receive the blocking signal a, the second inductor 7 is controlled to recover the induction effect, the second inductor 7 sends a blocking signal B, the control cabinet receives the blocking signal B, the elevator leveling is controlled, meanwhile, the control cabinet controls the first inductor 6 to close the induction effect, and the elevator continues to level; when the magnetic isolation plate is completely separated from the two sensors, as shown in fig. 6, the control cabinet does not receive the isolation signal B, the control cabinet controls the elevator to operate, and meanwhile, the control cabinet controls the first sensor 6 to recover the sensing effect.
When the elevator operates from bottom to top, the working principle operates from top to bottom.
When either the first sensor 6 or the second sensor fails, the operation results are as follows, taking the first sensor 6 as an example of failure.
When the magnetism isolating plate 5 runs to the first inductor 6, the first inductor 6 does not respond in time or the induction fails, the elevator does not respond and continues to run, when the magnetism isolating plate 5 isolates the second inductor 7, a separation signal B is generated, the control cabinet receives the separation signal B to control the elevator leveling, and when the magnetism isolating plate 5 completely breaks away from the second inductor 7, the elevator continues to run.
I.e. to single level inductor control.
So, when two responses are all effective, can not influence elevator normal work yet. When any one of the flat bed sensors fails, the normal operation of the elevator can be maintained.
In the embodiment, the distance between the two leveling inductors is smaller than the length of the magnetic isolation plate 5, and the magnetic isolation plate is an important characteristic for maintaining stable leveling work of the elevator. If the distance between the two leveling inductors is greater than the length of the magnetism isolating plate 5, a state inevitably exists, the magnetism isolating plate 5 is located between the first inductor 6 and the second inductor 7, the original figure 4 state is changed into that the magnetism isolating plate 5 is separated from the first inductor 6 but does not reach the second inductor 7, the elevator should continue to level and be immobile, and the movement of leveling, running and leveling is changed, so that bad riding experience is brought to passengers.
