[0002] A wire rope detection device is a digital non-destructive testing instrument that quantitatively detects wire rope damage through the principle of magnetic flux leakage. The wire rope detection device has the function of online detecting defects such as internal and external broken wires, wear, corrosion, loose strands, and wire skipping in the wire rope.

[0003] In the related art, common mine wire rope detection devices usually target single ropes or multiple ropes used for conventional mine transportation and load, and detect the surface or internal damage of their wire ropes. Such wire ropes are always in a state of single-head towing load during application, and there are no wire knots, slings, or other hanging loads on the wire ropes. For mine suspension wire ropes, due to obstacles such as wire rope knots, slings, or hanging tools on the mine suspension wire ropes, common mine wire rope detection devices are often difficult to detect due to the obstruction of the obstacles and need to be improved urgently.

[0013] As a further preference, the guiding structure includes a guiding plate, the guiding plate is fixedly arranged on the side surface of the probe body, and a guiding channel with a flared guiding inlet is formed between the guiding plates on two probe bodies.

[0014] As a further preference, the detection mechanism further includes a self-preloading clamping roller assembly arranged at the end of the probe body, which is used to apply a pre-tightening force to the wire rope entering and leaving the detection channel.

Detailed implementation manners

[0027] In order to make the objectives, technical solutions, and advantages of the present application clearer and more understandable, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0028] The following combines the attached Figures 1-4 to further describe the present application in detail.

[0029] An embodiment of the present application discloses a wire rope detection mechanism for mine hanging applications. Referring to Figures 1-4 , the wire rope detection mechanism for mine hanging applications includes two probe bodies 1 that can be opened and closed relative to each other, and a detection channel for the wire rope 2 to pass through is formed between the two probe bodies 1; guiding structures for guiding the obstacles 2-1 on the wire rope 2 are respectively arranged on the same side of the two probe bodies 1. When the guiding structures guide the obstacles 2-1, the guiding structures drive the two probe bodies 1 to open relative to each other under the extrusion force of the obstacles 2-1, so that the obstacles 2-1 can pass through the detection mechanism.

[0030] Further, in some embodiments, the guiding structure includes a rolling member 4 rotatably disposed on the side of the probe body 1, and the rolling member 4 has a guiding surface for fitting against the surface of the obstacle 2-1. Among them, the rolling members 4 can be individually installed on the side of the probe body 1 through components such as shaft rods and bearings; alternatively, a support base 5 can be fixedly provided on the side of the probe body 1, and the support base 5 is used as the overall installation foundation for multiple rolling members 4. In addition, the rolling member 4 can be a roller, a ball, a ball bearing, etc., and its rotation axis is preferably perpendicular to the opening direction of the detection channel.

[0031] Further, a plurality of rolling members 4 in the guiding structure are arranged in a row on one side of the probe body 1, and some of the rolling members 4 are arranged at the front end of the inlet of the detection channel to facilitate the smooth entry of the obstacle 2-1 between the two guiding structures.

[0032] Further preferably, among the plurality of rolling members 4 arranged in a row, some of the rolling members 4 are located in front of the side of the probe body 1 (i.e., the rolling member 4 is located on the side of the probe body 1 and at the same time in front of the inlet of the detection channel), and some of the rolling members 4 are located behind the side of the probe body 1 (i.e., the rolling member 4 is located on the side of the probe body 1 and at the same time behind the outlet of the detection channel). In addition, the plurality of rolling members 4 arranged in a row can be arranged in a straight line, a curve, a combination of a curve and a straight line, etc., and can be selected according to actual needs.

[0033] Further, a plurality of rows of rolling members 4 are arranged along the thickness direction of the probe body 1, and adjacent rows of rolling members 4 are arranged in a staggered manner. The rolling members 4 arranged in a plurality of rows in a staggered manner can provide multiple rolling support points for the obstacle 2-1.

[0034] Further, when the guiding structure includes a plurality of rolling members 4, the guiding structure can further include an anti-jamming member 6. The anti-jamming member 6 is disposed on the side of the probe body 1, and preferably, the anti-jamming member 6 is located between two adjacent rolling members 4 in the same row. The anti-jamming member 6 has a guiding surface for fitting against the obstacle 2-1 to prevent the obstacle 2-1 from getting stuck in the gap between adjacent rolling members 4.

[0035] Among them, the anti-jamming member 6 is preferably a rolling member such as a needle roller or a ball, and the rolling member is rotatably disposed on the side of the probe body 1 to assist in supporting and conducting the obstacle 2-1 through rolling contact. In other embodiments, the anti-jamming member 6 can also be a fixing member fixed to the side of the probe body 1, and the surface of the fixing member can also fit against and support the obstacle 2-1.

[0036] Specifically, referring to Figures 1-3, in some embodiments, a support base 5 is mounted on the side of the probe body 1. The support base 5 protrudes from both ends of the probe body 1, and a rolling member 4 and an anti-blocking member 6 are mounted on the support base 5. Among them, the rolling member 4 is a roller, and two sets of rollers are arranged side by side along the thickness direction of the probe body 1 (i.e., Figure 1 the direction indicated by arrow h in

[0037] ). The rollers in the same group are linearly arranged at the edge of the support base 5, so that a rolling guide channel is formed between the multiple rollers on the two probe bodies 1. To smoothly guide the obstacle 2-1, the inlet and outlet of the rolling guide channel are flared. The anti-blocking member 6 is a needle roller, which is rotatably mounted on the support base 5 and is spaced between the double rows of rollers.

[0038] Further, as Figure 4 shown, in some embodiments, the guiding structure includes a guiding plate 3. The guiding plate 3 is fixedly arranged on the side of the probe body 1, and a guiding channel with a flared guiding inlet is formed between the guiding plates 3 of the two probe bodies 1.

[0039] In this implementation scheme, when detecting the hanging steel wire rope 2, as the relative displacement between the steel wire rope 2 and the detection mechanism, the obstacles 2-1 such as the hanging tool on the steel wire rope 2 first enter the guiding channel along the flared guiding inlet. As the guiding channel gradually narrows, the obstacle 2-1 forms a sliding contact with the surface of the guiding plate 3, and then the obstacle 2-1 gradually presses the guiding plate 3. The pressed guiding plate 3 drives the two probe bodies 1 to open each other, so that the steel wire rope 2 can carry the obstacle 2-1 and pass through the detection mechanism smoothly.

[0040] Of course, in some embodiments, the above-mentioned rolling member 4 can also be mounted on the guiding plate 3, and the guiding plate 3 serves as the support base.

[0041] Further, a self-preloading roller assembly is also arranged at the end of the probe body 1, which is used to apply a preloading force to the steel wire rope 2 entering and exiting the detection channel, so as to position and guide the steel wire rope 2.

[0042] Further, in some embodiments, the self-preloading clamping roller assembly includes a clamping roller 7 and an elastic member 8. The clamping roller 7 is rotatably arranged at the end of the probe body 1. Under the elastic force of the elastic member 8, the clamping roller 7 approaches the detection channel to fit the steel wire rope 2. Of course, in other embodiments, the self-preloading clamping roller assembly may also include a plurality of support rollers rotatably installed at the end of the probe body 1, and the circumferential surface of the support rollers has an elastic layer for abutting against the steel wire rope 2.

[0043] Specifically, as Figures 1-3 , in this embodiment, supports 9 are fixed at both the detection inlet end and the detection outlet end of the probe body 1. A cantilever seat 10 is rotatably installed on the support 9. The clamping roller 7 is rotatably arranged at one end of the cantilever seat 10, and a push rod 11 is hinged at the other end of the cantilever seat 10.

[0044] The elastic member 8 includes, but is not limited to, a spring. One end of the spring is fixed to the support 9, and an annular seat 12 is fixed to the other end of the spring. The end of the push rod 11 away from the cantilever seat 10 penetrates through the spring and extends out of the annular seat 12, and a limit head 13 is connected to the end extending out of the annular seat 12. The limit head 13 preferably uses a nut. Among them, the size of the limit head 13 is larger than the central through hole of the annular seat 12, and the push rod 11 and the central through hole of the annular seat 12 are in clearance fit.

[0045] In this layout, the spring is in a compressed state. The elastic force of the spring is transmitted to the limit head 13 through the annular seat 12, so that the limit head 13 forms a pushing force on the push rod 11. Then, the push rod 11 pulls the cantilever seat 10 under the action of the force, driving the other end of the cantilever seat 10 to drive the clamping roller 7 to approach the detection channel.

[0046] Further, as Figure 2 shown, among the two probe bodies 1, the clamping roller 7 at the end of one probe body 1 is a grooved roller, and the clamping roller 7 at the end of the other probe body 1 is a flat roller. The grooved roller is a roller with grooves formed on its circumferential surface.

[0047] In other embodiments, the end of the probe body 1 is connected with a rotating seat through a telescopic rod. The telescopic rod is fixedly connected to the probe body 1, and the telescopic rod can be telescoped in the direction towards the detection channel. The clamping roller 7 can be rotatably installed on the rotating seat, and the elastic member 8 is connected to / abuts against the probe body 1 and the rotating seat, applying an elastic force to the rotating seat so that the clamping roller 7 approaches the detection channel.

[0048] Further, as Figures 1-3As shown, in some embodiments, the detection mechanism further includes a mounting base 14. A guide rod 15 is fixedly arranged in the mounting base 14. The two probe bodies 1 are slidably and adjustably mounted on the mounting base 14 through the guide rod 15. Through the guiding action of the guide rod 15, the two probe bodies 1 can approach and move away from each other to achieve opening and closing operations.

[0049] In addition, a driving structure (not shown in the figure) is also mounted on the mounting base 14. The driving structure can be a power source such as a cylinder or an electric push rod 11 for driving the position adjustment of the probe body 1; in some embodiments, the driving structure can be an elastic member such as a spring for applying an elastic force that makes the two probe bodies 1 approach each other.

[0050] It should be noted that a flaw detection component for magnetic flux leakage detection of the steel wire rope 2 is provided in the two probe bodies 1. The flaw detection component is a prior art and will not be elaborated here.
