[0019] Furthermore, when the detection device 1 and the detection device 2 are in use, the two guide grooves 33 are arranged on the outside of the steel wire rope, and the detection device 1 and the detection device 2 are fixed by the fixing assembly 4 to detect the steel wire rope.

[0020] The guide frame 11 includes a guide base frame 111 and a guide wheel fixing plate 112; the guide base frame 111 is a U-shaped structure, and the opening of the U-shaped structure is set upward; one end of the guide wheel fixing plate 112 is set on both sides of the guide base frame 111 through a fixed axis, and the other end of the guide wheel fixing plate 112 is rotatably set with a guide wheel part 12.

[0024] Furthermore, the buckle plate 131 is an arc-shaped structure bent toward the buckle portion 133 , and the buckle portion 133 is an arc-shaped structure bent toward the buckle plate 131 , and the buckle portion 133 and the buckle plate 131 are adapted to each other.

[0025] Furthermore, the buckling portion 133 and the buckling plate 131 are not limited to arc-shaped structures, but can also be structures such as curved surface structures that can buckle with each other.

[0026] The guide assembly 1 of the present invention is arranged at the upper and lower ends of the detection assembly 2 . Specifically, the bottom plate 132 is fixed to the upper end of the detection frame 24 or the lower end of the detection frame 24 .

[0027] The magnet body 1 21 , the magnet body 22 and the magnetic circuit 23 are arranged in contact with each other, and the detection frame 24 is arranged outside the magnet body 1 21 , the magnet body 22 and the magnetic circuit 23 .

[0028] The chimera 1 25 and the chimera 2 26 are respectively arranged at the upper and lower ends of the detection frame 24 , and the chimera 1 25 and the chimera 2 26 are respectively located outside the magnet 1 21 and the magnet 2 22 .

[0029] The magnetic circuit 23 is arranged in the detection frame 24, and a magnet body 21 and a magnet body 22 are arranged at the front end of the magnetic circuit 23. The magnet body 21 and the magnet body 22 are respectively arranged at the upper and lower ends of the magnetic circuit 23; an annular magnetic circuit is formed between the magnet body 21, the magnet body 22, the magnetic circuit 23 and the wire rope.

[0030] Furthermore, the magnet body 1 21 and the magnet body 2 22 can be permanent magnets or electromagnets, and the magnetic circuit 23 is a material with high magnetic permeability. The magnet body 1 21 and the magnet body 2 22 adhere to the magnetic circuit 23 through their own magnetic force, and the positions of the magnet body 1 21 and the magnet body 2 22 relative to the magnetic circuit 23 can remain unchanged.

[0031] Specifically, the rear sides of the magnet body 1 21 and the magnet body 2 22 are arranged at the front end of the magnetic circuit 23 , and the remaining parts of the magnet body 1 21 and the magnet body 2 22 are covered by the guide body 31 .

[0032] In the embodiment of the present invention, two groups of magnetic bodies 32 are disposed in the guide groove 33 . The rear ends of the two groups of magnetic bodies 32 are connected to a detection unit 38 . The detection unit 38 is located between the two groups of magnetic bodies 32 .

[0033] When the wire rope with a broken part passes through the magnetic body 32, the magnetic flux passes through the magnetic body 32 to the detection unit 38, so that the detection unit 38 can detect the magnetic flux leaking from the broken part, thereby detecting the broken part of the wire rope. The detection unit 38 is arranged between the two groups of magnetic bodies 32, so that the detection unit 38 can detect the leakage magnetic flux from the wire rope.

[0034] The magnetic body 32 includes a plurality of magnetic sensors 321 arranged at gaps. The magnetic sensors 321 are arranged to surround the outer surface of the wire rope when in use, and the leakage magnetic flux of the wire rope is measured by the magnetic sensors 321.

[0035] The detection unit 38 uses the leakage flux data measured by the magnetic body 32 to check the abnormal structure of the wire rope. When in use, the magnetic body 32 can detect the leakage of the wire rope and measure the magnetic flux over the entire length. After the detection is completed, it can be connected to an external signal processing device by wire or wirelessly to detect and process the detected data.

[0036] Furthermore, in order to facilitate the connection between the detection unit 38 and an external signal processing device, the detection unit 38 is provided with a storage unit, an interface unit, a data input and output unit, a communication unit, and other structures for transmitting and storing data. For example, the storage unit stores the detection data, the interface unit is connected to the external processing device, the data input and output unit is connected to the magnetic body 32 to receive or transmit information, and the communication unit has the function of connecting to the network to send the inspection results such as the number of disconnections to the processing device.

[0037] After the steel wire rope detection device with such a configuration is installed in the elevator, the magnetic body 32 can measure the leakage magnetic flux over the entire length of the steel wire rope by moving from the bottom layer to the top layer or from the top layer to the bottom layer. Then, using the measured leakage magnetic flux data, the detection unit 38 can detect abnormal conditions of the steel wire rope.

[0038] Furthermore, the steel wire rope is often composed of multiple strands of wires twisted around a fiber core. The magnetic sensors 321 in the magnetic body 32 can be arranged radially and axially along the steel wire rope, that is, two groups of magnetic bodies 32 are arranged in directions perpendicular to the outer surface of the steel wire rope. Therefore, the radial leakage magnetic flux and the longitudinal leakage magnetic flux at each position of the steel wire rope can be measured separately.

[0039] Furthermore, the number of the magnetic sensors 321 is twice the number of steel wire rope strands.

[0040] Furthermore, the present invention is not limited to setting two groups of magnetic bodies 32. When the width of the magnetic sensor 321 in the Z direction is larger than the diameter of the wire rope, when all the magnetic sensors 321 are arranged in a row, the magnetic sensors 321 will interfere with each other, and the magnetic sensors 321 will move along the longitudinal direction of the wire rope and increase the number of rows.

[0041] Furthermore, the detection component 2 and the guide component 3 are electrically connected during installation, so that the detection component 2 and the magnetic body 32 are electrically connected.

[0042] The guide groove 33 is in contact with the steel wire rope and is used to guide the steel wire rope when in use, so that the magnetic body 32 in the guide groove 33 can detect the steel wire rope.

[0043] Furthermore, the guide groove 33 is a U-shaped groove. Since the smaller the contact area between the steel wire 3 and the groove, the greater the surface pressure of the contact part, the tension on the U-shaped groove is smaller than that on the V-shaped groove, making it easier for the steel wire rope to move in the guide groove 33.

[0044] Furthermore, the size and structure of the embedding groove 1 34 , the embedding groove 2 35 and the magnet body 1 21 , the magnet body 2 22 are the same. During installation, the magnet body 1 21 , the magnet body 22 are placed in the embedding groove 1 34 , the embedding groove 2 35 .

[0045] The card block 1 36 and the card block 2 37 are both provided with card slots that are compatible with the chimera 1 25 and the chimera 2 26. During installation, the chimera 1 25 and the chimera 2 26 are placed in the card slots of the card block 1 36 and the card block 2 37, so that the guide component 3 and the detection component 2 are engaged and fixed.

[0046] The guide assembly 1, the detection assembly 2 and the guide assembly 3 of the present invention are detachably arranged. By replacing new detachable components, the maintenance and replacement of the detection device can be completed, and the elevator wire rope can be detected.

[0047] The fixing components 4 are provided on both sides of the device of the present invention, and are used to fix the detection devices on the left and right sides.

[0048] One side of the fixed plate 41 is fixed to the detection frame 24 on the detection device 1 through a fixed block 413. There is a gap between the fixed plate 41 and the detection device. A sliding groove 411 and a card slot 412 are provided on the fixed plate 41; the card slot 412 is located at one end of the sliding groove 411, and the card slot 412 is provided at one end close to the fixed block 413.

[0049] The fixing member 42 includes a head 421 , an end 422 and a sliding portion 423 ; the sliding portion 423 is provided with the head 421 at one end and with the end 422 at the other end, and the end 422 is matched with the fixing groove 43 .

[0050] The diameter of the slot 412 is between the head 421 and the end 422, ensuring that the end 422 can be placed in the slot 412 and the head 421 does not pass through the slot 412. When in use, the sliding portion 423 slides in the sliding slot 411 to the fixing slot 43 to fix the detection device 1 and the detection device 2 on the left and right sides.

[0051] A method for detecting an elevator wire rope comprises the following steps: S1. Put the elevator in maintenance state, ensure that the wire rope is in a stationary state, and prepare the elevator wire rope detection device; S2. Use the elevator wire rope detection device to detect the entire wire rope breakage situation; S3. The detected signals are collected and identified by an external computer to determine the specific situation and the corresponding position.

[0052] In step S1 , the guide component 3 is installed to the detection component 2 , and the guide component 1 and the detection component 2 at the upper and lower ends of the guide component 3 are fixed.

[0053] In step S2, the guide groove 33 is brought close to the surface of the wire rope and moved along the length direction of the wire rope. The magnetic sensor 321 collects the change signal of the leakage magnetic field, and the detection unit 38 performs detection.

[0054] In step S3, the collected signal can be amplified and filtered before being collected and identified by a computer. The computer counts the pulse signals sent by the position encoder and obtains the specific situation of the equivalent broken wire number and equivalent wear amount of the wire rope and the corresponding position through calculation and processing.

[0055] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
