Description

Technical Field

[0001] The utility model relates to the field of flaw detection of haulage steel ropes in coal mines, and particularly relates to a flaw detection device for the haulage steel rope of an overhead man-riding device in a coal mine. Background Art

[0002] As the main personnel transportation equipment in underground mining mines, the overhead man-riding device is widely used in underground coal mines due to its simplicity, convenience and other characteristics. The haulage steel rope, as an important part of it, plays a decisive role in the safety of personnel transportation. The haulage steel rope of the overhead man-riding device is mainly used to hang the passenger suspension chair. Usually, a suspension beam is arranged on the roadway shed, a tow rope wheel is hung below the suspension beam, and the haulage steel rope is hung above the supporting wheel. Both ends of the haulage steel rope are driven wheels, which drive the haulage steel rope to move through friction to achieve the purpose of personnel transportation. Personnel ride on the suspended passenger suspension chair and directly contact the haulage steel rope, hanging above the haulage steel rope and moving with the haulage steel rope.

[0003] In mines equipped with overhead pedestrian devices, underground workers basically need to use this transportation method for long-distance round trips underground. The haulage steel rope will be subjected to frequent and periodic tension. During long-term use, the haulage steel rope is prone to fatigue failure due to periodic stress. At the same time, due to the characteristics of humid air and water spray underground, the haulage steel rope is prone to lose its stability due to corrosion. The safety of the haulage steel rope is always related to the life safety of underground workers and the safe and efficient production of the mine.

[0004] At present, the safety inspection of the overhead man-riding device mainly relies on manual periodic disassembly inspection, repair, etc. Generally, the inspection period is relatively long, which leads to problems such as large inspection difficulty, low efficiency, and high time cost required for inspection, greatly affecting the safety of the haulage steel rope operation and the operation efficiency of the overhead man-riding device. Content of the Utility Model

[0005] Aiming at the above-mentioned existing technical deficiencies, the purpose of the utility model is to provide a flaw detection device for the haulage steel rope of an overhead man-riding device in a coal mine, which can install the flaw detection device on the tow rope wheel suspension rod and realize real-time detection as the haulage steel rope runs, so as to realize accurate, automatic and efficient flaw detection of the haulage steel rope of the overhead man-riding device.

[0006] To solve the above technical problems, the utility model adopts the following technical solutions:

[0007] The utility model provides a flaw detection device for the traction steel wire rope of an overhead passenger device in a coal mine. The device includes a suspension rod suspended and fixed on a beam body. A rope dragging wheel adapted to the traction steel wire rope is arranged at the bottom of the suspension rod. A probe support is horizontally rotatably connected above the rope dragging wheel on the suspension rod. An ultrasonic flaw detection wheel adapted to the traction steel wire rope and capable of being disassembled is arranged on the probe support. A punctuation marker for aligning with the traction steel wire rope, a coupling liquid sprayer for spraying coupling liquid onto the ultrasonic flaw detection wheel, a cleaning brush for cleaning the traction steel wire rope, and a central processor are also arranged on the probe support. A stabilizing pressure rod is hinged between the probe support and the suspension rod. The stabilizing pressure rod cooperates with the swinging probe support to closely attach the ultrasonic flaw detection wheel to the traction steel wire rope, so that the ultrasonic flaw detection wheel has an elastic vertical free swinging space to adapt to the swing generated by the force on the traction steel wire rope. The ultrasonic flaw detection wheel, the coupling liquid sprayer, and the punctuation marker are electrically connected to the central processor and controlled by it.

[0008] Preferably, the stabilizing pressure rod includes a sleeve and a protruding rod nested together. A spring is fixedly connected to the bottom of the cavity of the sleeve at the end where the protruding rod extends into the sleeve.

[0009] Preferably, the probe support is connected to the suspension rod through a support fixator. The support fixator includes two clamping plates. The two clamping plates are fixedly connected by bolts and clamped on the suspension rod. A cylinder rotatably connected to the probe support is arranged on one of the clamping plates.

[0010] Preferably, the stabilizing pressure rod is connected to the suspension rod through a pressure rod fixator. The pressure rod fixator includes two pressing plates clamped and fixed on the suspension rod by bolts. A rod body limiting plate is arranged on one of the pressing plates. One end of the stabilizing pressure rod is hinged on the rod body limiting plate.

[0011] Preferably, when the probe support is horizontal, the stabilizing pressure rod 8 forms an angle of 30 - 45°.

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0024] As Figures 1 to 3As shown in the figure, a flaw detection device for the traction steel wire rope of an overhead passenger device in a coal mine includes a suspension rod 3 fixedly suspended on a beam 1 through a hanger 2. A rope dragging wheel 7 adapted to the traction steel wire rope is provided at the bottom of the suspension rod 3. A probe support 6 is horizontally rotatably connected above the rope dragging wheel 7 on the suspension rod 3. An ultrasonic flaw detection wheel 9 adapted to the traction steel wire rope and capable of being disassembled is provided on the probe support 6. A punctuation marker 12 for aligning with the traction steel wire rope, a coupling liquid sprayer 11 for spraying coupling liquid onto the ultrasonic flaw detection wheel 9, a cleaning brush 13 for cleaning the traction steel wire rope, and a central processing unit 10 are also provided on the probe support 6. A stable pressure rod 8 is also hinged between the probe support 6 and the suspension rod 3. The stable pressure rod 8 cooperates with the swinging probe support 6 to closely fit the ultrasonic flaw detection wheel 9 and the traction steel wire rope 14, so that the ultrasonic flaw detection wheel 9 has an elastic vertical free swinging space to adapt to the swing generated by the traction steel wire rope 14 under force, effectively ensuring the stability of the flaw detection device during operation. The ultrasonic flaw detection wheel 9, the coupling liquid sprayer 11, and the punctuation marker 12 are electrically connected to the central processing unit 10 and controlled by it.

[0025] The stable pressure rod 8 includes a sleeve 15 and a protruding rod 17 nested together. A spring 16 is fixedly connected to the bottom of the cavity of the sleeve 15 at one end where the protruding rod 17 extends into the sleeve 15.

[0026] The probe support 6 is connected to the suspension rod 3 through a support fixer 5. The support fixer 5 includes two clamping plates. The two clamping plates are fixedly connected by bolts and clamped on the suspension rod 3. A cylinder rotatably connected to the probe support 6 is provided on one of the clamping plates.

[0027] The stable pressure rod 8 is connected to the suspension rod 3 through a pressure rod fixer 4. The pressure rod fixer 4 includes two pressing plates 20 clamped and fixed on the suspension rod 3 by bolts. A rod body limiting plate 22 is provided on one of the pressing plates 20. One end of the stable pressure rod 8 is hinged on the rod body limiting plate 22.

[0028] When the probe support 6 is horizontal, the stable pressure rod 8 forms an angle of 30 - 45°.

[0029] During operation, the traction steel wire rope 14 moves by itself to drive the ultrasonic flaw detection wheel 9 to rotate to achieve in-situ flaw detection. When the overhead pedestrian device is running, the traction steel wire rope 14 rotates to drive the ultrasonic flaw detection wheel 9 to rotate. The distal end sends a flaw detection instruction to the central processing unit 10. The central processing unit controls the ultrasonic flaw detection wheel 9 to start flaw detection and controls the coupling liquid sprayer 11 to spray coupling liquid onto the surface of the ultrasonic flaw detection wheel 9. The central processing unit sends the flaw detection result information to the distal end in real time. When the central processing unit 10 detects an abnormal signal, it sends a punctuation instruction to the punctuation marker 12, and the punctuation marker 12 marks the position on the traction steel wire rope 14 through a spray pipe.

[0030] Environmental factors such as dampness and dust in the mine shaft can easily cause impurities such as dust particles to adhere to the surface of the traction steel wire rope, thus affecting the accuracy of ultrasonic detection. The cleaning brush 13 of this device is designed to be detachable and replaceable. During the operation of the device, the cleaning brush 13 can clean the bottom of the traction steel wire rope in advance. At the same time, in order to further optimize the influence of the air in the isolation gap on the detection accuracy of the ultrasonic flaw detection wheel, a coupling liquid sprayer 11 is arranged on the side of the cleaning brush 13 facing the ultrasonic flaw detection wheel 9 to spray the coupling agent on the ultrasonic flaw detection wheel 9.

[0031] Obviously, those skilled in the art can make various changes and modifications to the present utility model without departing from the spirit and scope of the present utility model. Thus, if these modifications and variations of the present utility model fall within the scope of the claims of the present utility model and its equivalent technologies, the present utility model is also intended to include these changes and modifications.
