Description

Technical Field

[0001] This utility model relates to the field of steel rope technology, specifically a steel rope broken wire deformation detection device. Background Technology

[0002] Steel ropes are the main load-bearing components in engineering projects and are widely used in major industries and sectors of the national economy, such as coal, metallurgy, transportation, construction, and tourism. Their safe use is of great concern. At present, electromagnetic non-destructive testing of steel ropes can detect the leakage magnetic field of the metal cross-sectional area loss of steel ropes, and can detect internal broken wires and wear, the degree of corrosion, and steel rope deformation, which affect the service life of steel ropes.

[0003] According to Chinese Patent Publication No. CN217739074U, a non-destructive testing instrument for steel wire rope is disclosed. This instrument detects the degree of damage to the steel wire using a magnetic induction detector and uses two electric guide wheels in conjunction with a periodic correction component to periodically straighten the steel wire. Straightening the steel wire improves the detection effect. Because the correction is periodic, it does not affect the traction and recovery of the steel wire, ensuring continuous operation of the equipment, improving efficiency, and adapting to different specifications of steel wire surfaces, thus broadening its applicability. This solves the problem of traditional equipment lacking periodic correction functions when testing steel wire, causing the steel wire to easily deviate and bend, resulting in decreased test results. Furthermore, in this technical solution, when the steel wire rope passes through the magnetic induction detector, metal or other foreign objects may adhere to the rope, affecting the magnetic field distribution and leading to the risk of misjudgment or missed detection by the magnetic induction detector, thus affecting the accuracy of steel wire testing. Therefore, we propose a steel wire breakage and deformation detection device. Utility Model Content

[0006] Preferably, a rotating shaft is fixedly installed at the output end of the motor, and a gear is fixedly installed at the top end of the rotating shaft. The gear meshes with a gear ring. By setting the rotating shaft, the motor can drive the gear to rotate through the rotating shaft, and the gear can drive the gear ring to rotate, thereby realizing transmission.

[0007] Preferably, a T-shaped ring plate is fixedly installed at the top of the toothed ring, and a T-shaped ring groove is provided at the bottom of the outer shell. The T-shaped ring plate and the T-shaped ring groove are rotatably connected. By setting the T-shaped ring plate and the T-shaped ring groove, the toothed ring can be limited, so that the toothed ring can be fixedly rotated at the bottom of the outer shell.

[0008] Preferably, a slider is fixedly installed at the bottom of the card frame, and a groove is opened at the top of the cleaning ring. The slider is slidably connected to the groove. A limit rod is fixedly installed on the inner wall of the groove. The limit rod moves through the slider.

[0011] This invention provides a device for detecting broken wire deformation in steel ropes. This device offers the following advantages:

[0012] (1) The steel rope broken wire deformation detection device enables the wire brush to sweep off any metal or other foreign matter that may be attached to the surface of the steel rope, preventing the attached metal or other foreign matter from following the steel rope through the magnetic induction detector, affecting the magnetic field distribution, and causing the magnetic induction detector to misjudge or miss detection, thus ensuring the accuracy of steel rope detection. Furthermore, by setting a magnetic ring, the iron filings attached to the surface of the steel rope can be further adsorbed, further improving the accuracy of steel rope broken wire deformation detection.

[0013] (2) The steel rope broken wire deformation detection device makes it easy for personnel to disassemble the cleaning ring and magnetic ring, thereby facilitating the cleaning of the cleaning ring and magnetic ring after long-term use, ensuring the quality of subsequent steel rope treatment by the steel wire brush and magnetic ring on the cleaning ring.

[0021] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0022] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In addition, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] like Figure 1-6 As shown, this utility model provides a technical solution: a steel rope broken wire deformation detection device, including a fixed bracket 1, a shell 2 fixedly installed on the outside of the fixed bracket 1, a magnetic induction detector 3 installed inside the shell 2, openings at both the top and bottom of the shell 2, a toothed ring 8 rotatably connected to the bottom of the shell 2, a support plate 4 fixedly installed on the outside of the fixed bracket 1, a motor 5 fixedly installed at the top of the support plate 4, the toothed ring 8 being drivenly connected to the motor 5, a fixed connecting rod 11 fixedly rotated at the bottom of the toothed ring 8, a cleaning ring 24 provided below the toothed ring 8, a wire brush 18 fixedly installed inside the cleaning ring 24, a rod groove 12 opened at the top of the cleaning ring 24, the fixed connecting rod 11 being inserted into the rod groove 12, a retaining frame 13 slidably connected to the top of the cleaning ring 24, a retaining groove 23 opened on the outer wall of the fixed connecting rod 11, and the retaining frame 13 being engaged in the retaining groove 23.

[0025] Among them, the magnetic detector 3 is the disclosed technology in the announcement number CN217739074U, entitled "A Non-destructive Testing Instrument for Steel Wire Rope", so it is not described or drawn in detail in this article and in the accompanying drawings.

[0026] Specifically, in the above technical solution, the steel rope broken wire deformation detection device, during use, passes the steel rope sequentially from the bottom opening of the outer casing 2 through the magnetic induction detector 3 and the top opening of the outer casing 2. Then, the steel rope is conveyed upwards by the unwinding and traction equipment. When the steel rope passes through the magnetic induction detector 3, because the steel wire rope is made of high-quality carbon steel, a ferromagnetic material, it will be magnetized under the influence of an external magnetic field. When defects such as broken wires, wear, corrosion, or deformation occur on the steel wire rope, the magnetic field distribution and magnetic flux at the defect location will change. Therefore, this characteristic can be utilized to monitor various defects on the steel wire rope through the magnetic induction detector 3. Before the steel wire rope passes through the magnetic induction detector 3, the motor 5 is started. The motor 5 drives the rotating shaft 6 to rotate, the rotating shaft 6 drives the gear 7 to rotate, and the gear 7 drives the gear ring 8 to rotate. Ring 8 drives cleaning ring 24 to rotate via fixed connecting rod 11. Cleaning ring 24 drives wire brush 18 to rotate, allowing wire brush 18 to sweep off any metal or other foreign matter that may be attached to the surface of the steel rope. This prevents attached metal or other foreign matter from following the steel rope through magnetic detector 3, affecting the magnetic field distribution, and causing the magnetic detector 3 to misjudge or miss detection, thus ensuring the accuracy of steel rope detection. Furthermore, by setting magnetic ring 19, iron filings attached to the surface of the steel rope can be further adsorbed, further improving the accuracy of steel rope wire breakage and deformation detection. When it is necessary to clean wire brush 18, the clamping frame 13 can be pulled outward, causing the clamping frame 13 to drive slider 15 to compress spring 17, causing the clamping frame 13 to disengage from the clamping slot 23, so that the clamping frame 13 no longer limits the cleaning ring 24. At this time, the cleaning ring 24 can be detached from fixed connecting rod 11.

[0027] Furthermore, a rotating shaft 6 is fixedly installed at the output end of the motor 5, and a gear 7 is fixedly installed at the top of the rotating shaft 6, which meshes with the gear ring 8;

[0028] In this system, by setting a rotating shaft 6, the motor 5 can drive the gear 7 to rotate, and the gear 7 can drive the gear ring 8 to rotate, thereby realizing transmission.

[0029] Furthermore, a T-shaped ring plate 9 is fixedly installed on the top of the toothed ring 8, and a T-shaped ring groove 10 is opened at the bottom of the outer shell 2. The T-shaped ring plate 9 and the T-shaped ring groove 10 are rotatably connected.

[0030] The T-shaped ring plate 9 and T-shaped ring groove 10 can limit the toothed ring 8, allowing the toothed ring 8 to rotate in a fixed position at the bottom of the outer shell 2.

[0031] Furthermore, a slider 15 is fixedly installed at the bottom of the card frame 13, and a groove 14 is opened at the top of the cleaning ring 24. The slider 15 is slidably connected to the groove 14. A limit rod 16 is fixedly installed on the inner wall of the groove 14. The limit rod 16 moves through the slider 15. A spring 17 is fixedly connected between one side of the slider 15 and the inner wall of the groove 14.

[0032] The limiting rod 16 can limit the movement of the slider 15 and the spring 17, ensuring the stability of the slider 15 when moving and the spring 17 when compressed.

[0033] Furthermore, a magnetic ring 19 is engaged inside the toothed ring 8, and a positioning block 21 is fixedly installed on the outer wall of the magnetic ring 19. A positioning groove 20 is opened at the bottom end of the toothed ring 8, and the positioning block 21 is engaged in the positioning groove 20. A bolt 22 is threadedly connected to the positioning block 21, and the positioning block 21 is fixedly connected to the toothed ring 8 by the bolt 22.

[0034] The magnetic ring 19 can further adsorb iron filings attached to the surface of the steel rope, thereby improving the accuracy of detecting broken wire deformation of the steel rope. The magnetic ring 19 can be removed from below the toothed ring 8 by unscrewing the bolt 22 on the positioning block 21.

[0035] Furthermore, there are two positioning blocks 21 and two positioning slots 20, and the positioning blocks 21 and the positioning slots 20 are compatible.

[0036] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
