Examples

Referring to fig. 1-2, the present embodiment provides a comb detection system 1000 for a comb plate 600. The comb detection system 1000 includes an electrical signal detection device 100, a power source 200, and an inductive wire 300 electrically connected in sequence to form a closed loop. The sensing wire 300 is disposed at the teeth 610 of the comb plate 600.

In use, if the teeth 610 of the comb plate 600 are damaged, the sensing wire 300 is directly damaged, and thus the circuit is broken, and the electrical signal received by the electrical signal detecting apparatus 100 is changed. In other words, it is possible to directly judge whether or not the teeth 610 of the comb plate 600 are defective by monitoring the change of the electric signal detection device 100.

By this design, a unified monitoring and management of the integrity of the comb plate 600 of the escalator can be achieved, and once the tooth 610 defect occurs, it can be found at the first time, facilitating a quick process.

In general, the comb detection system 1000 has a simple structure, is easy to implement and apply, can detect the defect problem of the comb plate 600 very sensitively and accurately, and has high response rate, safety and reliability.

In the present embodiment, the sensing wire 300 includes a first wire 310, a second wire 320, and a third wire 330 sequentially disposed along an arrangement direction of the teeth 610 of the comb plate 600. The first wire 310, the second wire 320 and the third wire 330 are arranged in parallel. That is, along the arrangement direction of the teeth 610 of the comb plate 600 (i.e., the length direction of the comb plate 600), the first wire 310 is engaged with the teeth 610 of the previous stage, the second wire 320 is engaged with the teeth 610 located at the middle, and the third wire 330 is engaged with the teeth 610 of the next stage.

With the above design, the tooth 610 of the entire comb plate 600 is divided into three parts, which are monitored by the first wire 310, the second wire 320, and the third wire 330, respectively. If the tooth 610 of any one of the first wire 310, the second wire 320 and the third wire 330 is defective, the electrical signal is changed. If the teeth 610 of the corresponding portion of any one of the first wire 310, the second wire 320, and the third wire 330 are defective, the degree of change in the electrical signal is different. If the teeth 610 of the corresponding portions of the first wire 310, the second wire 320, and the third wire 330 are defective, the electrical signal is changed to the greatest extent. By monitoring the degree of change in the electrical signal, the number of defective portions can be determined. Another advantage of this structural design is: when a defect occurs in one area, the normal monitoring of the other two areas is not affected.

Further, referring to fig. 3, the sensing wire 300 has V-shaped wire segments 340 for mating with the teeth 610 and a connecting segment 350 for connecting two adjacent wire segments 340 (the first wire 310, the second wire 320 and the third wire 330 all have V-shaped wire segments 340 for mating with the teeth 610 and a connecting segment 350 for connecting two adjacent wire segments 340). Each tooth 610 is embedded with wire segments 340, and the wire segments 340 are arranged in parallel and at intervals. The wire segment 340 and the connection segment 350 are both made of conductive material.

The plane of the central axis of the wire segment 340 is perpendicular to the plate surface of the comb plate 600, and the wire segment 340 extends along the extending direction of the upper and lower sidewalls of the tooth 610. The connection sections 350 are each disposed along the arrangement direction of the teeth 610 of the comb plate 600.

Specifically, the wire segment 340 has a V-shape corresponding to the structure of the tooth 610, and the wire segment 340 is embedded in the tooth 610. Two adjacent wire segments 340 are connected by a connecting segment 350, and if any group of connecting segments 350 between two adjacent wire segments 340 are connected between the upper ends of the wire segments 340, the connecting segments 350 adjacent to the connecting segments are connected between the lower ends of the wire segments 340, and the upper ends and the lower ends are alternately arranged in sequence.

With the above design, the arrangement of the sensing wires 300 is more orderly, and the sensing wires 300 are also more saved. The structural design of the V-shaped wire segment 340 also makes it more sensitive to the defection of the tooth 610. Even if the tooth 610 is only damaged at the upper or lower portion or the front end, the sensing wire 300 is damaged, thereby greatly improving the detection sensitivity.

It should be noted that, in other embodiments of the present invention, the first wire 310, the second wire 320 and the third wire 330 may be matched with the electrical signal detecting device 100, so as to quickly and accurately locate the defect area, as shown in fig. 4.

Further, in the present embodiment, referring to fig. 5 to 11, the sensing wire 300 is disposed on the comb plate 600, and the electrical signal detecting device 100 and the power source 200 are disposed on the elevator end cover 700. The sensing wire 300 is detachably and electrically connected with the detection circuit through a mating terminal.

The mating terminals include a first terminal 400 and a second terminal 500.

The first terminals 400 are disposed on the comb plate 600 and have a hemispherical shape, and the first terminals 400 protrude from the surface of the comb plate 600.

The second terminal 500 is provided to the elevator end deck board 700, and the second terminal 500 includes a base 510 and an abutment piece 520.

The abutment 520 has one end connected to the base 510 and the other end bent toward one side of the base 510 (the side where the first side wall 511 is located), and further bent toward the side wall of the base 510, and further bent toward itself to form a curved shape. The plurality of abutment pieces 520 are distributed in an annular array along the edge of the base sheet 510 to enclose an abutment for abutment with the first terminal 400.

The base sheet 510 is in the shape of a cake, and the abutment sheet 520 is attached to the annular side wall of the base sheet 510. The thickness of the base sheet 510 is twice the thickness of the abutment sheet 520. At the connection portion between the abutment 520 and the base 510, a side wall surface of the abutment 520 near the first side wall 511 is connected to the first side wall 511.

One end (trailing end) of the abutment piece 520 remote from the base sheet 510 is bent to be parallel to the first side wall 511.

In the present embodiment, the number of the abutment pieces 520 is three, and the three abutment pieces 520 enclose a structure for abutting against the first terminal 400.

When the first terminal 400 is electrically connected to the second terminal 500, the first terminal 400 abuts against the second terminal 500. The first terminal 400 is fitted to an annular region surrounded by the abutment 520, and the first terminal 400 is in contact with the abutment 520.

Through above structural design, the butt piece 520 has sufficient elasticity, and when first terminal 400 and second terminal 500 electricity are connected, first terminal 400 accomplishes the cooperation through extrusion butt piece 520, can guarantee like this that first terminal 400 and second terminal 500 fully cooperate, guarantees that the circuit is unobstructed.

In use, even if the contact piece 520 is disassembled and reassembled a plurality of times, the contact piece 520 has sufficient resetting capability, so that the first terminal 400 and the second terminal 500 can be fully attached in the long-term use process.

In addition, the stability after the above structural cooperation is completed is very high, and the first terminal 400 is not easily detached.

Further, the first side wall 511 of the substrate 510 is further connected to a rubber gasket 530, and the tail end of the abutment piece 520 is embedded in the rubber gasket 530. Wherein a portion of the trailing end of the abutment piece 520 remains exposed to the outside of the rubber gasket 530.

By this design, the rubber gasket 530 can not only further provide a supporting force to the abutting piece 520, enhance the restoring ability and elastic ability of the abutting piece 520, but also prevent the trailing end of the abutting piece 520 from contacting the first side wall 511 of the base sheet 510, avoid the generation of local mess, and also avoid damage to the abutting piece 520 and the base sheet 510.

Specifically, after the rubber gasket 530 is disposed, when the first terminal 400 presses the abutment piece 520 to be matched with the second terminal 500, the rubber gasket 530 can play a role in stabilizing the tail end of the abutment piece 520, so that the tail end of the abutment piece 520 is prevented from being excessively displaced, and the overall structural stability of the abutment piece 520 is ensured.

The present embodiment also provides a comb tooth detection method using the comb tooth detection system 1000, which includes: with the power supply 200 for voltage stabilization, when a change in the electrical signal of the electrical signal detecting device 100 is detected, the integrity of the comb plate 600 is detected. The specific operation manner is described in detail above, and will not be repeated here.
