[0026] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0027] Example 1: Figures 1 to 3 As shown, a wire rope diameter laser detection device described in an embodiment of the present invention includes a protective shell 1, which is formed by two groups of shells 101 fastened together by bolts, and a lifting ring 2 is fixedly installed on the outside of the two groups of shells 101, a laser emitting end 4 is fixedly installed in one group of shells 101, and a laser receiving end 5 is fixedly installed in the other group of shells 101, and the laser emitting end 4 and the laser receiving end 5 are directly opposite to each other. Two groups of guide wheels 6 are symmetrically rotated in the two groups of shells 101, and an oil scraper ring 3 is provided at one end of the protective shell 1. The oil scraper ring 3 is formed by two groups of semi-ring bodies 301 fastened together by bolts, and an oil scraper groove 302 for engaging the groove on the wire rope 7 is provided in the semi-ring body 301.

[0028] Specifically, the laser emitting end 4 and the laser receiving end 5 are connected to an external signal receiver through a wire. In the initial state, the two groups of semi-ring bodies 301 are in a separated state, and the two groups of shells 101 are in a separated state. When the diameter of the wire rope 7 needs to be measured, the two combined shells 101 are first combined onto the wire rope 7 to be measured, so that the wire rope 7 passes between the laser emitting end 4 and the laser receiving end 5, and the wire rope 7 is clamped between the two groups of guide wheels 6. Then, the two groups of semi-ring bodies 301 are merged onto the wire rope 7, and the oil scraping groove 302 on the semi-ring body 301 is completely engaged with the groove on the wire rope 7. Then, by fixing one end of the two groups of ropes to the two groups of lifting rings 2 and the other end of the rope to the fixed object, the entire protective shell 1 is limited, and then the wire rope 7 is driven to move. Figure 1 The direction indicated by the middle arrow is the moving direction of the wire rope 7. At this time, the oil scraper ring 3 will move with the wire rope 7 until the end of the oil scraper ring 3 is unable to move by the protective shell 1. The wire rope 7 will pass through the oil scraper ring 3, and the oil scraper groove 302 slides along the groove on the wire rope 7, causing the oil scraper ring 3 to rotate. At the same time, the oil scraper groove 302 scrapes off the oil stains on the wire rope 7. After the oil stains are scraped off, the wire rope 7 moves along the two sets of guide wheels 6 to between the laser emitting end 4 and the laser receiving end 5. The laser emitting end 4 emits an infrared laser, and the laser beam irradiates the surface of the wire rope 7 and is reflected. The laser receiving end 5 receives the reflected beam. The external signal receiver calculates the diameter of the wire rope 7 through the geometric relationship between the positions of the laser emitting end 4, the wire rope 7 and the laser receiving end 5. Compared with the existing technology, the oil scraper ring 3 can fit tightly with the groove on the wire rope 7 through the oil scraper groove 302, thereby scraping off the oil stains on the wire rope 7 more cleanly, thereby improving the accuracy of wire rope 7 diameter detection.

[0029] like Figures 4 to 6 As shown, a docking mechanism 8 is provided between the protective housing 1 and the oil scraper ring 3. The docking mechanism 8 comprises two groups of semicircular sleeves 801, one end of the two groups of semicircular sleeves 801 is fixedly connected to the two groups of housings 101, two groups of sliding sleeves 804 are symmetrically mounted on the other end of the semicircular sleeves 801, an outer semi-rotary ring 805 fixedly connected to the sliding sleeves 804, and a plurality of groups of rollers 806 are installed in the outer semi-rotary ring 805 for rotation at equal angles. The semi-ring body 301 is fixedly connected to the inner semi-rotary ring 303, and the structure formed by the two groups of inner semi-rotary rings 303 is rotatably connected to the two groups of outer semi-rotary rings. The structure formed by the connecting ring 805 is that an arc groove 304 for limiting the roller 806 is provided on the inner half rotating ring 303, and the roller 806 is connected to the arc groove 304 in a rolling manner. A rectangular groove 802 is provided on the semicircular sleeve 801, and the rectangular groove 802 is slidably connected to the L-shaped clamping rod 803 for limiting the outer half rotating ring 805. Two sets of guide grooves 807 are symmetrically provided on the other end of the semicircular sleeve 801, and a guide column 808 is fixedly installed in the guide groove 807. The sliding sleeve 804 is slidably connected to the guide column 808, and a spring 809 is sleeved on the guide column 808.

[0030] Specifically, as the oil scraping ring 3 scrapes the oil dirt on the steel wire rope 7, a large amount of oil dirt will be attached to the oil scraping ring 3, so when the oil scraping ring 3 is disassembled, the oil dirt on the oil scraping ring 3 must be cleaned first, and then the fastening bolt can be found. Secondly, after the fastening bolt on the oil scraping ring 3 is attached to the oil dirt, the wrench will slip when it is rotated, which makes it more difficult for the worker to disassemble the oil scraping ring 3. In the initial state, the two groups of outer half rotary connecting rings 805 are in a merged state, so when the oil scraping ring 3 is installed, first separate the two groups of outer half rotary connecting rings 805, and the spring 809 is in a compressed state. Then place the half ring body 301 together with the inner half rotary connecting ring 303 on the steel wire rope 7, and at the same time make one end of the inner half rotary connecting ring 303 abut against the inner wall of one group of semicircular sleeves 801. Then adjust the position of the half ring body 301 until the oil scraping groove 302 on the half ring body 301 can tightly fit the groove on the steel wire rope 7. Then place another group of half ring bodies 301 on the steel wire rope 7 in the same way, loosen the two groups of outer half rotary connecting rings 805, and under the rebounding force of the spring 809, make the sliding sleeve 804 slide along the guide column 808, and at the same time the sliding sleeve 804 drives the two groups of outer half rotary connecting rings 805 to move towards each other until the two groups of outer half rotary connecting rings 805 are merged. The two groups of inner half rotary connecting rings 303 are located inside the two groups of outer half rotary connecting rings 805, and the rollers 806 are located in the arc-shaped grooves 304. Then push the two groups of L-shaped clamping rods 803 to slide along the corresponding rectangular grooves 802, and make one end of the L-shaped clamping rod 803 limit the outer half rotary connecting ring 805, so as to realize the installation of the oil scraping ring 3. When scraping oil, the steel wire rope 7 drives the oil scraping ring 3 together with the two groups of merged inner half rotary connecting rings 303 to rotate, and the several groups of rollers 806 roll along the arc-shaped grooves 304. When the oil scraping ring 3 needs to be disassembled, push the two groups of L-shaped clamping rods 803 to release the limiting of the two groups of L-shaped clamping rods 803 on the two groups of outer half rotary connecting rings 805, and separate the two groups of outer half rotary connecting rings 805 by pulling them up. The two groups of half ring bodies 301 can be separated directly from the steel wire rope 7, so as to facilitate the disassembly of the oil scraping ring 3 by the worker.

[0031] Embodiment two: as Figure 7 With Figure 8As shown, the comparative example one, wherein another embodiment of the application is: the upper end of the guide column 808 is symmetrically provided with two sets of limiting mechanisms 810, the limiting mechanism 810 includes two sets of limiting blocks 8101, the limiting block 8101 is fixedly installed on the guide column 808, the unlocking block 8102 is movably installed between the two sets of limiting blocks 8101, two sets of stop blocks 8103 are fixedly installed on both sides of the unlocking block 8102, two sets of sliding grooves 8081 are symmetrically formed on the upper end of the guide column 808, the sliding groove 8081 is slidingly connected with the guide rail 8104, the guide rail 8104 is fixedly connected with the unlocking block 8102, two sets of elastic steel strips 8041 are symmetrically fixedly installed on the sliding sleeve 804, the upper end of the elastic steel strip 8041 is welded with a clamping head 8042 for clamping the two sets of limiting blocks 8101, the limiting block 8101 is provided with a first inclined surface 11, and the unlocking block 8102 is provided with a second inclined surface 21.

[0032] Specifically, when installing the oil scraper ring 3, on the one hand, the two sets of outer half-rotating connecting rings 805 need to be kept separate, and on the other hand, the half-ring body 301 needs to be installed, so two people need to cooperate and operate, and the two people need to be skilled, which increases the difficulty of installing the oil scraper ring 3. Secondly, the working environment of the steel wire rope 7 is generally suitable for one person to operate. In the initial state, the unlocking block 8102 is combined with the two sets of limiting blocks 8101, and the height of the unlocking block 8102 is greater than the height of the limiting block 8101, so the two sets of outer half-rotating connecting rings 805 can be separated first. In this process, the outer half-rotating connecting ring 805 drives the sliding sleeve 804 to slide along the guide column 808, and the sliding sleeve 804 compresses the spring 809. At the same time, the sliding sleeve 804 drives the two sets of elastic steel bars 8041 together with the corresponding clamping heads 8042 to move towards the limiting mechanism 810. Until the clamping head 8042 is pressed onto the first inclined surface 11 of the limiting block 8101, and the clamping head 8042 slides along the first inclined surface 11, at the same time, the first inclined surface 11 pushes the clamping head 8042 to make the elastic steel bar 8041 bend. In this process, the clamping head 8042 pushes the unlocking block 8102, which drives the guide rail 8104 to slide along the sliding groove 8081, so that the unlocking block 8102 is separated from the two sets of limiting blocks 8101. Until the clamping head 8042 clamps the two sets of limiting blocks 8101 under the rebounding force of the elastic steel bar 8041, the sliding sleeve 804 is limited, so that the two sets of outer half-rotating connecting rings 805 cannot be combined. After the two sets of half-ring bodies 301 together with the inner half-rotating connecting ring 303 are combined on the steel wire rope 7, one hand of the worker keeps the two sets of half-ring bodies 301 combined, and the other hand continues to pull up one set of outer half-rotating connecting rings 805. At this time, the unlocking block 8102 is blocked by the inner wall of the sliding groove 8081 and cannot continue to move. The outer half-rotating connecting ring 805 that continues to move makes the clamping head 8042 continue to move towards the unlocking block 8102, and the clamping head 8042 is pressed by the second inclined surface 21 on the unlocking block 8102. Until the clamping head 8042 is blocked by the inner wall of the sliding groove 8081 and cannot move. At this time, under the rebounding force of the elastic steel bar 8041, the clamping head 8042 is tightly attached to the unlocking block 8102, and the outer half-rotating connecting ring 805 is loosened. Under the rebounding force of the spring 809, the clamping head 8042 drives the unlocking block 8102 to move towards the limiting block 8101, until the unlocking block 8102 is combined with the two sets of limiting blocks 8101 again. At the same time, the blocking block 8103 on both sides of the unlocking block 8102 is blocked by the two sets of limiting blocks 8101, so that the clamping head 8042 is instantaneously offset from the unlocking block 8102 and the two sets of limiting blocks 8101, thereby releasing the limitation of the sliding sleeve 804. According to the same method, the other set of outer half-rotating connecting rings 805 is pulled up, and the installation of the oil scraper ring 3 is realized. The cooperation of the limiting mechanism 810, the clamping head 8042, and the elastic steel bar 8041 makes the installation of the oil scraper ring 3 only need one person to operate, saves manpower, is simple and convenient to operate, and improves the practicality of the device.
