Description

Technical Field

[0001] The invention belongs to the technical field of other special equipment manufacturing, in particular to a laser detection device for the diameter of a steel wire rope. Background Art

[0002] Wire ropes will wear out during use, which will reduce their diameter. Since the diameter of the wire rope directly affects its carrying capacity, it is necessary to regularly inspect the wire rope diameter to detect the reduction in diameter in time and take appropriate measures, such as replacing the wire rope or adjusting the conditions of use. This will help prevent accidents caused by wire rope breakage or excessive deformation, and ensure the safety of personnel and equipment.

[0003] Patent publication number CN120101667A discloses an infrared laser diameter detection device and detection method for a wire rope, including a mounting base, to which is connected a measuring component for measuring the diameter of the wire rope, the measuring component including a housing, a limit roller, a laser emitting end, a laser receiving end, a limit ring plate, a connecting guide plate, an arc plate, and a limit slider; this scheme automatically drives the laser emitting end and the laser receiving end on the arc plate to rotate circumferentially relative to the wire rope through the cooperation between the wire rope, the driven slide rod and the cleaning arc block, while cleaning the oil stains adhering to the outside of the wire rope, thereby effectively improving the accuracy of measuring the diameter of the wire rope.

[0004] In the above scheme, before measuring the wire rope, it is necessary to scrape off the oil and dirt on the wire rope through the cleaning arc block and the driven slide rod. The cleaning arc block scrapes off the oil and dirt on the surface of the wire rope, and the driven slide rod scrapes off the oil and dirt in the grooves on the wire rope. Since the wire rope has many grooves and this scheme only designs two sets of driven slide rods, it is impossible to clean the oil and dirt on the wire rope. Secondly, the driven slide rod, the cleaning arc block and the wire rope are not closely enough, so the oil and dirt are not cleaned cleanly, which affects the accuracy of the wire rope diameter detection. For this reason, the present invention provides a wire rope diameter laser detection device. Summary of the Invention

[0005] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0006] The technical solution adopted by the present invention to solve its technical problem is as follows: a wire rope diameter laser detection device according to the present invention includes a protective housing, which is formed by fastening and merging two groups of housings by bolts, with hanging rings fixedly installed on the outside of the two groups of housings, a laser emitting end fixedly installed in one group of housings, and a laser receiving end fixedly installed in the other group of housings, the laser emitting end and the laser receiving end facing each other, two groups of guide wheels symmetrically rotating in the two groups of housings, an oil scraper ring provided at one end of the protective housing, the oil scraper ring formed by fastening and merging two groups of semi-ring bodies by bolts, and an oil scraping groove provided in the semi-ring body for engaging with the groove on the wire rope; The oil scraper ring can fit tightly with the groove on the wire rope through the oil scraper groove, thereby scraping off the oil stains on the wire rope more cleanly and improving the accuracy of wire rope diameter detection.

[0007] Preferably, a docking mechanism is provided between the protective shell and the oil scraper ring, the docking mechanism includes two groups of semicircular sleeves, one end of the two groups of semicircular sleeves are fixedly connected to the two groups of shells, two groups of sliding sleeves are symmetrically movably installed on the other end of the semicircular sleeves, an outer half rotating ring fixedly connected to the sliding sleeve, and several groups of rollers are rotatably installed in the outer half rotating ring at equal angles, the semi-ring body is fixedly connected to the inner half rotating ring, and the structure formed by the combination of the two groups of inner half rotating rings is rotatably connected to the structure formed by the combination of the two groups of outer half rotating rings, an arc groove for limiting the roller is provided on the inner half rotating ring, and the roller rolls in the arc groove, a rectangular groove is provided on the semicircular sleeve, and an L-shaped clamping rod for limiting the outer half rotating ring is slidably connected in the rectangular groove, and two groups of guide grooves are symmetrically provided on the other end of the semicircular sleeve, a guide post is fixedly installed in the guide groove, the sliding sleeve is slidably connected to the guide post, and a spring is provided on the guide post; When the oil scraper ring needs to be removed, push the two sets of L-shaped clamping rods to release the limit of the two sets of outer half rotating rings by the two sets of L-shaped clamping rods, and pull up the two sets of outer half rotating rings to separate them, and directly separate the two sets of half rings from the wire rope, so as to facilitate the staff to remove the oil scraper ring.

[0008] Preferably, two groups of limit mechanisms are symmetrically provided on the upper end of the guide post, and the limit mechanisms include two groups of limit blocks, the limit blocks are fixedly mounted on the guide post, an unlocking block is movably mounted between the two groups of limit blocks, and two groups of stoppers are fixedly mounted on both sides of the unlocking block. Two groups of slide grooves are symmetrically provided on the upper end of the guide post, the slide grooves are slidably connected to the guide rails, and the guide rails are fixedly connected to the unlocking blocks. Two groups of elastic steel bars are symmetrically fixedly mounted on the sliding sleeve, and a clamping head for clamping the two groups of limit blocks is welded on the upper end of the elastic steel bars. A first inclined surface is provided on the limit block, and a second inclined surface is provided on the unlocking block. The coordinated setting of the limiting mechanism, the clamping head and the elastic steel strip enables the installation of the oil scraper ring to be performed by only one person, thus saving manpower, making the operation simple and convenient, and improving the practicability of the device.

[0009] The beneficial effects of the present invention are as follows: 1. The oil scraper ring can fit closely with the groove on the wire rope through the oil scraper groove, thereby scraping off the oil stains on the wire rope more cleanly and improving the accuracy of wire rope diameter detection.

[0010] 2. When scraping oil, the wire rope drives the oil scraper ring together with the two combined sets of inner half-swivel rings to rotate, and several sets of rollers roll along the arc groove. When the oil scraper ring needs to be removed, push the two sets of L-shaped clamping rods to release the two sets of L-shaped clamping rods from limiting the two sets of outer half-swivel rings, and pull up the two sets of outer half-swivel rings to separate them. The two sets of half rings can be directly separated from the wire rope, which makes it easier for the staff to disassemble the oil scraper ring.

[0011] 3. After the two sets of half rings and the inner half rotating ring are combined onto the wire rope, the staff keeps the two sets of half rings closed with one hand and continues to pull up a set of outer half rotating rings with the other hand. At this time, the unlocking block is blocked by the inner wall of the slideway and cannot move further. The outer half rotating ring that continues to move makes the chuck continue to move toward the unlocking block, and the chuck is squeezed by the second inclined surface on the unlocking block until the chuck is blocked by the inner wall of the slideway and cannot move. At this time, under the action of the rebound force of the elastic steel bar, the chuck is close to the unlocking block, loosening the outer half rotating ring. Under the action of the spring rebound force, the clamping head drives the unlocking block to move toward the limit block until the unlocking block is merged with the two sets of limit blocks again. At the same time, the blocks on both sides of the unlocking block are blocked by the two sets of limit blocks, so that the clamping head instantly staggers the unlocking block and the two sets of limit blocks, thereby releasing the limit on the sliding sleeve. According to the same method, pull up the other set of outer half rotating rings to realize the above-mentioned installation of the oil scraper ring. The coordinated setting of the limit mechanism, the clamping head and the elastic steel bar allows the installation of the oil scraper ring to be operated by only one person, saving manpower, simple and convenient operation, and improving the practicality of the device.

[0022] 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.

[0023] 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.

[0024] 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.

[0025] 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.

[0026] Specifically, as the oil scraper ring 3 scrapes the oil dirt on the wire rope 7, a large amount of oil dirt will adhere to the oil scraper ring 3. Therefore, when disassembling the oil scraper ring 3, the oil dirt on the oil scraper ring 3 must be cleaned off before the fastening bolts can be found. Secondly, when the fastening bolts on the oil scraper ring 3 are attached to the oil dirt, the wrench will slip when the bolt is tightened with a wrench, making it difficult for the staff to disassemble the oil scraper ring 3. In the initial state, the two sets of outer half rotating rings 805 are in a combined state. Therefore, when installing the oil scraper ring 3, First, separate the two sets of outer half rotating rings 805, and put the spring 809 in a compressed state. Then, place the half ring body 301 together with the inner half rotating ring 303 on the wire rope 7, and at the same time make one end of the inner half rotating ring 303 rest against the inner wall of a set of semi-circular 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 fit tightly with the groove on the wire rope 7. Then, place the other set of half ring bodies 301 on the wire rope 7 in the same way, and loosen the two sets of outer half rotating rings 80 5. Under the rebound force of the spring 809, the sliding sleeve 804 slides along the guide post 808. At the same time, the sliding sleeve 804 drives the two sets of outer half rotating rings 805 to move toward each other until the two sets of outer half rotating rings 805 are merged. The merged two sets of inner half rotating rings 303 are located inside the merged two sets of outer half rotating rings 805, and the roller 806 is located in the arc groove 304. Then, the two sets of L-shaped clamping rods 803 are pushed to slide along the corresponding rectangular grooves 802, so that one end of the L-shaped clamping rod 803 limits the outer half rotating ring 805. Thus, the oil scraper ring 3 is installed. When scraping oil, the wire rope 7 drives the oil scraper ring 3 together with the two combined sets of inner half rotating rings 303 to rotate, and several sets of rollers 806 roll along the arc groove 304. When the oil scraper ring 3 needs to be disassembled, the two sets of L-shaped clamping rods 803 are pushed to release the limit of the two sets of L-shaped clamping rods 803 on the two sets of outer half rotating rings 805, and the two sets of outer half rotating rings 805 are pulled up to separate them, and the two sets of half ring bodies 301 can be directly separated from the wire rope 7, thereby facilitating the staff to disassemble the oil scraper ring 3.

[0027] Example 2: Figure 7 and Figure 8As shown, compared with Example 1, another embodiment of the present invention is: two groups of limiting mechanisms 810 are symmetrically arranged on the upper end of the guide column 808, the limiting mechanism 810 includes two groups of limiting blocks 8101, the limiting blocks 8101 are fixedly installed on the guide column 808, the unlocking block 8102 is movably installed between the two groups of limiting blocks 8101, and two groups of blocking blocks 8103 are fixedly installed on both sides of the unlocking block 8102, two groups of sliding grooves 8081 are symmetrically opened on the upper end of the guide column 808, the sliding grooves 8081 are slidingly connected to the guide rails 8104, and the guide rails 8104 are fixedly connected to the unlocking blocks 8102, and two groups of elastic steel bars 8041 are symmetrically fixedly installed on the sliding sleeve 804, and a clamping head 8042 for clamping the two groups of limiting blocks 8101 is welded on the upper end of the elastic steel bar 8041, a first inclined surface 11 is provided on the limiting block 8101, and a second inclined surface 21 is provided on the unlocking block 8102.

[0028] Specifically, when installing the oil scraper ring 3, on the one hand, it is necessary to keep the two groups of outer semi-rotary rings 805 separated, and on the other hand, it is necessary to install the semi-ring body 301. Therefore, two people are required to cooperate in the operation, and the two people are required to cooperate skillfully, which increases the difficulty of installing the oil scraper ring 3. Secondly, the working environment of the wire rope 7 is generally only suitable for one person to operate. In the initial state, the unlocking block 8102 is merged with the two groups of limit blocks 8101. The height of the unlocking block 8102 is greater than the height of the limit block 8101. Therefore, the two groups of outer semi-rotary rings 805 can be separated first. During this process, the outer semi-rotary 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 groups of elastic steel bars 8041 together with the corresponding clamping head 8042 moves toward the limiting mechanism 810 until the clamping head 8042 is squeezed onto the first inclined surface 11 on the limiting block 8101, and the clamping head 8042 slides along the first inclined surface 11, and at the same time, the first inclined surface 11 pushes the clamping head 8042 to bend the elastic steel bar 8041. During this process, the clamping head 8042 will push the unlocking block 8102, so that the unlocking block 8102 drives the guide rail 8104 to slide along the slide groove 8081, so that the unlocking block 8102 is separated from the two sets of limiting blocks 8101, until the clamping head 8042 is clamped with the two sets of limiting blocks 8101 under the action of the rebound force of the elastic steel bar 8041, thereby limiting the sliding sleeve 804, so that the two sets of outer semi-rotating rings 805 cannot be After the two groups of semi-ring bodies 301 and the inner semi-rotary ring 303 are merged onto the wire rope 7, the staff member keeps the two groups of semi-ring bodies 301 closed with one hand and continues to pull up a group of outer semi-rotary rings 805 with the other hand. At this time, the unlocking block 8102 is blocked by the inner wall of the slide groove 8081 and cannot move further. The outer semi-rotary ring 805 that continues to move causes the clamping head 8042 to continue to move toward the unlocking block 8102, and the clamping head 8042 is squeezed by the second inclined surface 21 on the unlocking block 8102 until the clamping head 8042 is blocked by the inner wall of the slide groove 8081 and cannot move. At this time, under the rebound force of the elastic steel bar 8041, the clamping head 8042 is close to the unlocking block 8102, loosening the outer semi-rotary ring 805. Under the action of the rebound force of the spring 809, the clamping head 8042 drives the unlocking block 8102 to move toward the limit block 8101 until the unlocking block 8102 merges with the two groups of limit blocks 8101 again, and at the same time, the blocks 8103 on both sides of the unlocking block 8102 are blocked by the two groups of limit blocks 8101, so that the clamping head 8042 instantly staggers the unlocking block 8102 and the two groups of limit blocks 8101, thereby releasing the limit on the sliding sleeve 804. According to the same method, pull up the other group of outer half rotating rings 805 to realize the above-mentioned installation of the oil scraper ring 3. The coordinated setting 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 require one person to operate, saving manpower, simple and convenient operation, and improving the practicality of the device.

[0029] Working principle: First, put the two combined shells 101 together on the steel wire rope 7 to be measured, so that the steel wire rope 7 passes between the laser emitting end 4 and the laser receiving end 5, and the steel wire rope 7 is clamped between the two sets of guide wheels 6, then merge the two sets of semi-ring bodies 301 onto the steel wire rope 7, and the oil scraping groove 302 on the semi-ring body 301 is completely engaged with the groove on the steel wire rope 7, and then fix one end of the two sets of ropes to the two sets of rings 2, and fix the other end of the rope to the fixed object, so that the entire protective shell 1 is limited, and then drive the steel wire rope 7 to move, and attach 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 protected by the protective shell 1 and cannot move. 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 the oil stains on the wire rope 7. The wire rope 7 after scraping the oil stains moves along the two sets of guide wheels 6 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 light beam. The external signal receiver calculates the diameter of the wire rope 7 through the geometric relationship between the laser emitting end 4, the wire rope 7 and the laser receiving end 5. When installing the oil scraper ring 3, first separate the two groups of outer half rotating rings 805, and the spring 809 is in a compressed state. Then, place the half ring body 301 together with the inner half rotating ring 303 on the wire rope 7, and at the same time make one end of the inner half rotating ring 303 rest against the inner wall of a group of semicircular sleeves 801, then adjust the position of the half ring body 301 until the oil scraper groove 302 on the half ring body 301 can fit tightly with the groove on the wire rope 7, and then place the other group of half ring bodies 301 on the wire rope 7 in the same way, loosen the two groups of outer half rotating rings 805, and under the action of the rebound 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 rotating rings 805 to move toward each other until the two groups of outer half rotating rings 805 merge. The two combined inner half swivel rings 303 are located in the two combined outer half swivel rings 805, and the rollers 806 are located in the arc grooves 304. Then, the two groups of L-shaped clamping rods 803 are pushed to slide along the corresponding rectangular grooves 802, so that one end of the L-shaped clamping rod 803 limits the outer half swivel ring 805, thereby realizing the installation of the oil scraper ring 3. When scraping oil, the wire rope 7 drives the oil scraper ring 3 to rotate together with the two combined inner half swivel rings 303, and several groups of rollers 806 roll along the arc grooves 304. When the oil scraper ring 3 needs to be removed, the two groups of L-shaped clamping rods 803 are pushed to release the two groups of L-shaped clamping rods 803 from limiting the two groups of outer half swivel rings 805, and the two groups of outer half swivel rings 805 are pulled up to separate, and the two groups of half ring bodies 301 can be directly separated from the wire rope 7. The two sets of outer half rotating rings 805 can be separated first. During this process, the outer half rotating rings 805 drive 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 strips 8041 together with the corresponding clamping heads 8042 to move toward the limiting mechanism 810 until the clamping heads 8042 are squeezed onto the first inclined surface 11 on the limiting block 8101, and the clamping heads 8042 slide along the first inclined surface 11. At the same time, the first inclined surface 11 pushes the clamping heads 8042 to bend the elastic steel strips 8041 During this process, the clamping head 8042 will push the unlocking block 8102, so that the unlocking block 8102 drives the guide rail 8104 to slide along the slide groove 8081, so that the unlocking block 8102 is separated from the two sets of limit blocks 8101, until the clamping head 8042 is clamped with the two sets of limit blocks 8101 under the rebound force of the elastic steel bar 8041, so as to limit the sliding sleeve 804, so that the two sets of outer half rotating rings 805 cannot be combined. After the two sets of half ring bodies 301 together with the inner half rotating ring 303 are combined onto the wire rope 7, the staff keeps the two sets of half ring bodies 301 together with the inner half rotating ring 303. The ring body 301 is closed, and the other hand continues to pull up a set of outer half rotating rings 805. At this time, the unlocking block 8102 is blocked by the inner wall of the slide groove 8081 and cannot move further. The outer half rotating ring 805 that continues to move causes the clamping head 8042 to continue to move toward the unlocking block 8102, and the clamping head 8042 is squeezed by the second inclined surface 21 on the unlocking block 8102 until the clamping head 8042 is blocked by the inner wall of the slide groove 8081 and cannot move. At this time, under the action of the rebound force of the elastic steel bar 8041, the clamping head 8042 is close to the unlocking block 8102, and the outer half rotating ring 805 is released. The semi-rotary ring 805, under the action of the rebound force of the spring 809, causes the clamping head 8042 to drive the unlocking block 8102 to move toward the limit block 8101 until the unlocking block 8102 is merged with the two groups of limit blocks 8101 again. At the same time, the blocks 8103 on both sides of the unlocking block 8102 are blocked by the two groups of limit blocks 8101, so that the clamping head 8042 is instantly offset from the unlocking block 8102 and the two groups of limit blocks 8101, thereby releasing the limit on the sliding sleeve 804. According to the same method, pull up another group of outer semi-rotary rings 805 to realize the above-mentioned installation of the oil scraper ring 3.
