[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. By setting a tensioning mechanism, when the cover plate and the placement plate are in the process of mold closing, the cover plate drives the L-shaped trapezoidal block to move downward synchronously while pressing down. When the inclined surface at one end of the L-shaped trapezoidal block contacts the spherical rod, the spherical rod is pushed by the action of the inclined surface to drive the first roller to move forward through the sliding plate, so that the first roller and the second roller are misaligned. When the sliding plate moves forward, since the rack 2 is fixed, the rack 2 drives the gear 1 to drive the first roller to rotate in the direction of the wire rope, thereby squeezing the wire rope. The tensioning mechanisms set at both ends of the placement plate are staggered. Under the action of the staggered tensioning mechanisms, the wire rope can be offset to the right at one end of the placement plate and to the left at the other end, so that the wire rope entering the inner side of the placement plate can be in a taut state, thereby improving the accuracy of wire rope detection;

[0017] 2. By setting a clamping mechanism, the elastic coefficient of the second spring is greater than the elastic coefficient of the third spring. When the lower abutting wheel squeezes the second spring, the lower abutting wheel moves downward inside the groove of the placement plate, so that the pressure on the rack 1 is gradually reduced, so that the rack 1 moves in the direction of the gear 2 under the action of the third spring, thereby driving the bidirectional screw rod to rotate, and then driving the movable plate and the fixed seat 2 to move relative to each other, so that the upper abutting wheel and the lower abutting wheel can adaptively press the wire rope. At the same time, the first roller and the second roller can synchronously and adaptively abut on both sides of the wire rope, so as to facilitate the subsequent tightening operation of the wire rope, thereby improving the overall practicality of the device;

[0018] 3. By setting up the cooperation of components such as bidirectional screw rods, multiple balls can be embedded in the outer walls of the upper abutment wheel and the lower abutment wheel, and the balls can be distributed around, so that when the upper abutment wheel and the lower abutment wheel abut against the outer wall of the wire rope to move, the friction between them and the wire rope is reduced. When the wire rope needs to be inspected, the lower abutment wheel inside the groove of the placement plate is first abutted against the bottom of the wire rope, and then the staff aligns the cover plate with the placement plate and presses it down. At this time, the upper abutment wheel and the lower abutment wheel clamp the wire rope, so that the wire rope can be in the middle position between the cover plate and the placement plate, so that the non-destructive flaw detection head can better detect the surface of the wire rope. When non-destructive testing is performed, when it is necessary to test steel wire ropes of different thicknesses, when the staff presses the cover plate down and closes the mold with the placement plate, the upper abutment wheel and the lower abutment wheel are respectively subjected to resistance, and the first spring and the second spring are squeezed at the same time, so that the upper abutment wheel and the lower abutment wheel can adaptively press the steel wire rope, so that the upper abutment wheel and the lower abutment wheel can clamp the steel wire ropes of different thicknesses. No matter how the thickness of the steel wire rope changes, the upper abutment wheel and the lower abutment wheel can maintain a stable clamping of the steel wire rope, preventing the steel wire rope from sliding or deflecting during the testing process, thereby improving the accuracy of subsequent testing;

[0019] 4. By setting up the connection components, when the wire rope needs to be tested, the staff will first arrange the wire ropes that need to be tested one by one, and then take out the corresponding number of wire rope detection devices according to the number of wire ropes, and then splice the connecting rods into the appropriate length, align the slots at the bottom of the corresponding number of detection devices with the connecting rods and slide them in. After moving to the appropriate position, insert the card block into the slot to fix the detection device, thereby realizing the simultaneous detection of multiple wire ropes, thereby improving the overall detection efficiency, and then improving the overall practicality of the device.

[0036] A plurality of balls can be embedded in the outer walls of the upper abutment wheel 14 and the lower abutment wheel 18, and the balls can be distributed in a circumferential manner, so that when the upper abutment wheel 14 and the lower abutment wheel 18 abut against the outer wall of the wire rope for movement, the friction between them and the wire rope is reduced.

[0037] Example 3

[0038] The tensioning mechanism is located at both ends of the placement plate 1. When the steel wire rope is tested, the steel wire rope inside the placement plate 1 and the cover plate 2 is tightened to facilitate better detection of the damaged part of the steel wire rope. The tensioning mechanism includes a movable plate 9 and a fixed seat 28 arranged at the front and rear ends of the placement plate 1. The top of the fixed seat 28 is rotatably connected to the second roller 7. The top of the movable plate 9 is slidably connected to the sliding plate 10. The top of the sliding plate 10 is rotatably connected to the fixed seat 13. A fourth spring 29 is installed between the sliding plate 10 and the movable plate 9. The top of the fixed seat 13 is rotatably connected to the first roller 6. The inner part of the placement plate 1 is provided with a spring 29.

The L-shaped trapezoidal blocks 4 are located above the spherical rod 11. One end of the fixed seat 13 is fixedly connected to a gear 12, and the gear 12 is rotatably connected to the sliding plate 10 through a rotating shaft. One side of the movable plate 9 is fixedly connected to a rack 2 30 meshing with the gear 12. The bottom of the L-shaped trapezoidal block 4 is provided with an inclined surface. The top of the movable plate 9 is provided with a through groove having a diameter greater than that of the L-shaped trapezoidal block 4. The width of the trapezoidal block 4 is greater than the diameter of the spherical rod 11. The transverse drive includes a fixed seat 31 fixedly connected to both ends of the placement plate 1. The inner side of the fixed seat 31 is rotatably connected with a bidirectional screw 8. The inner side of the fixed seat 31 is located above the bidirectional screw 8 and is fixedly connected to a limit plate 27. The movable plate 9 and the fixed seat 28 are respectively slidably connected to the outer wall of the limit plate 27. The outer wall of the bidirectional screw 8 is provided with a positive thread and a negative thread. The movable plate 9 and the fixed seat 28 are respectively threadedly connected to the outer wall of the positive thread and the negative thread.

The connecting rope 2 2 is fixedly connected to a rack 26, a docking groove 36 communicating with the slide groove 35 is provided on the inner side of the placement plate 1, and the diameter of the docking groove 36 matches the width of the rack 26, the interior of the docking groove 36 is fixedly connected to the limit plate 24, a third spring 25 is installed between the rack 26 and the limit plate 24, the connecting rope 22 passes through the lower limit plate 21 and the limit plate 24 and is fixedly connected to one end of the rack 26, the interior of the placement plate 1 is rotatably connected to the limit wheel 23, the limit wheel 23 is attached to the inner side of the connecting rope 22, and the outer wall of the bidirectional screw rod 8 is fixedly connected to a gear 2 33 meshing with the rack 26;

[0039] The elastic coefficient of the second spring 20 is greater than the elastic coefficient of the third spring 25. When the lower abutting wheel 18 squeezes the second spring 20, the lower abutting wheel 18 moves downward inside the groove of the placement plate 1, so that the pressure on the rack 1 26 is gradually reduced, so that the rack 1 26 moves in the direction of the gear 2 33 under the action of the third spring 25, thereby driving the bidirectional screw rod 8 to rotate, and then driving the movable plate 9 and the fixed seat 2 28 to move relative to each other, so that the upper abutting wheel 14 and the lower abutting wheel 18 can adaptively press the wire rope. At the same time, the first roller 6 and the second roller 7 can synchronously and adaptively abut on both sides of the wire rope, so as to facilitate the subsequent tightening operation of the wire rope, thereby improving the overall practicality of the device;

[0040] When the cover plate 2 and the placement plate 1 are in the process of mold closing, the cover plate 2 drives the L-shaped trapezoidal block 4 to move downward synchronously while being pressed down. When the inclined surface at one end of the L-shaped trapezoidal block 4 contacts the spherical rod 11, the spherical rod 11 is pushed by the action of the inclined surface to drive the first roller 6 to move forward through the sliding plate 10, so that the first roller 6 and the second roller 7 are misaligned. When the sliding plate 10 moves forward, since the rack 2 30 is fixed, the gear 1 12 is driven by the rack 2 30 to drive the first roller 6 to rotate in the direction of the wire rope, thereby squeezing the wire rope. The tensioning mechanisms arranged at both ends of the placement plate 1 are staggered. Under the action of the staggered tensioning mechanisms, the wire rope can be offset to the right at one end of the placement plate 1 and to the left at the other end, so that the wire rope entering the inner side of the placement plate 1 can be in a taut state, thereby improving the accuracy of wire rope detection;

[0041] When the cover plate 2 and the placement plate 1 are fitted together, the two can be fixed by a bolt assembly, and then the non-destructive flaw detection head 3 is started. The steel wire rope in a straight state is more easily scanned by the non-destructive flaw detection head 3 to find the damaged part, making the data detected by the non-destructive flaw detection head 3 more accurate.

[0042] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
