Description

Technical Field

[0001] This utility model relates to the field of detection device technology, and in particular to a detection device for lifting slings. Background Technology

[0002] During the manufacturing process, lifting slings need to undergo tensile testing under simulated tensile loads in real-world usage scenarios to assess their ultimate load-bearing capacity and safety, thereby ensuring their proper use.

[0003] In actual production, various lengths of lifting slings will be produced according to specific needs. As the length of the lifting sling increases, the length used for testing will also increase, which will increase the requirements for the length of the testing equipment's operating space. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a detection device for lifting slings.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a detection device for a lifting sling, comprising a detection platform, on which two sliding seats are symmetrically arranged about the middle of the detection platform are slidably disposed, and each sliding seat is provided with a positioning seat. The detection platform is provided with a displacement mechanism for driving the two sliding seats to move closer or further apart from each other. Two mounting seats are slidably disposed on the top of the detection platform, and both mounting seats are located between the two sliding seats. One mounting seat is rotatably mounted with two first limiting posts, and the other mounting seat is rotatably mounted with a second limiting post. The detection platform is provided with a moving mechanism for adjusting the distance between the two mounting seats.

[0006] By adopting the above technical solution, during the testing of lifting slings, the lifting sling is first passed between two first limiting posts and two second limiting posts in sequence, and both ends of the lifting sling are respectively placed on positioning seats. Then, the distance between the two sets of mounting seats is adjusted by the moving mechanism, and the first and second limiting posts move away from each other until the lifting sling is taut. Finally, the displacement mechanism drives the two sliding seats away from each other until the two sliding seats move to the maximum distance. If the lifting sling does not break, it can be said that the lifting sling is qualified. By adjusting the two sets of mounting seats, it can adapt to the testing of lifting slings of various lengths, reducing the requirements for the length of the testing site.

[0007] Furthermore, the displacement mechanism includes an annular frame fixed to the top of the detection platform, a bidirectional threaded rod rotatably installed in the annular frame, two limiting blocks slidably disposed in the annular frame, and a displacement motor fixed to the detection platform and driving the bidirectional threaded rod to rotate. Both limiting blocks are threadedly connected to the bidirectional threaded rod, and the two limiting blocks are respectively fixed to two sliding seats. The bidirectional threaded rod is provided with two threaded grooves with opposite directions of rotation and equal pitch, and the two threaded grooves are respectively threadedly connected to the two bidirectional threaded rods.

[0008] By adopting the above technical solution, after the displacement motor works, it drives the ring frame to rotate. Since both limit blocks are threadedly connected to the bidirectional threaded rod, and the two limit blocks are fixed to the two sliding seats respectively, the bidirectional threaded rod is provided with two threaded grooves with opposite directions and equal pitch. The two threaded grooves are threadedly connected to the two bidirectional threaded rods respectively, so that the two limit blocks, the sliding seats connected to the two limit blocks, and the positioning seats connected to the two sliding seats all move away from each other until the side walls of the two limit blocks move away from each other and fit against the side walls on both sides of the ring frame. At this point, it can be determined whether the lifting belt is qualified.

[0009] Furthermore, the top of the testing platform is provided with a sliding groove. The moving mechanism includes a threaded column rotatably installed in the sliding groove, the threaded column passing through the testing platform and rotatably connected. The moving mechanism also includes a moving motor fixed to the testing platform and driving the threaded column to rotate, a gear fixedly sleeved on the threaded column, and a moving block slidably disposed in the sliding groove and threadedly connected to the threaded column. The moving block is fixed to the mounting base. The number of sliding grooves, the number of threaded columns, the number of gears, the number of moving blocks, and the number of mounting bases are equal and their positions correspond one-to-one. Two of the gears mesh.

[0010] By adopting the above technical solution, after the mobile motor works, it drives the threaded column connected to its output end to rotate. Due to the meshing of the two sets of gears, the two sets of threaded columns rotate synchronously in opposite directions, causing the moving block threadedly connected to the two sets of threaded columns and the mounting seat connected to the two moving blocks to move closer or further away from each other, thereby realizing the distance between the first limit column and the second limit column.

[0011] Furthermore, the sliding seat is provided with an adjustment mechanism. The number of adjustment mechanisms is equal to the number of sliding seats and their positions correspond one-to-one. The adjustment mechanism includes an adjustment component, which includes an electro-hydraulic push rod fixed on the sliding seat and an L-shaped mounting bracket fixed to the end of the push rod of the electro-hydraulic push rod. The positioning seat is fixed on the mounting bracket. The adjustment mechanism also includes a clamping component for clamping the lifting sling.

[0012] By adopting the above technical solution, during the process of putting the lifting sling on the positioning seat, the electric hydraulic push rod first works and its push rod end extends, so that the mounting bracket connected to the push rod end of the electric hydraulic push rod and the positioning seat connected to the mounting bracket both move, thereby changing the distance between the two sets of positioning seats, making it easier for a shorter lifting sling to be put on the positioning seat.

[0013] Furthermore, the clamping assembly includes a fixing block fixed to the top of the sliding seat, and the horizontal end of the mounting bracket is provided with a limiting through hole that slides with the fixing block. The number of limiting through holes is equal to the number of fixing blocks and their positions correspond one-to-one. The clamping assembly also includes a movable clamping block fixed to the top of the fixing block.

[0014] By adopting the above technical solution, as the two sets of positioning seats approach each other, the positioning seats gradually move away from the moving clamp until the moving clamp fits against the vertical section of the mounting frame. At this point, the lifting sling can be placed on the positioning seat. Then, the push rod end of the electric hydraulic push rod retracts and resets, the two sets of positioning seats move away from each other, the positioning seats move closer to the mounting seat, and finally the positioning seat and the mounting seat clamp the lifting sling, which improves the stability of the lifting sling during testing.

[0015] Furthermore, the detection platform is provided with limiting components. The number of limiting components is equal to the number of sliding seats and their positions correspond one-to-one. The limiting components include a fixed seat fixed to the top of the detection platform and two third limiting columns of the detection platform rotatably mounted on the fixed seat.

[0016] By adopting the above technical solution, after the hoisting sling passes through the first and second limiting posts in sequence, the side walls at both ends of the hoisting sling are then passed between the third limiting posts of the two detection platforms on the same side, which improves the stability of the hoisting sling during detection.

[0017] Furthermore, the movable clamping block is fixed with a plug plate, and the positioning seat is provided with a through hole that engages with the plug plate. The number of plug plates, the number of plug holes, and the number of movable clamping blocks are equal and their positions correspond one-to-one.

[0018] By adopting the above technical solution, as the positioning seat approaches the mounting seat, the insert plate is gradually inserted into the insertion hole. The insert plate limits the lifting sling, reducing the probability of the lifting sling falling off during the test.

[0019] Furthermore, the bottom of the sliding seat is rotatably mounted with multiple rollers that are all rolledly connected to the top of the detection platform.

[0020] By adopting the above technical solution, the friction between the positioning seat and the detection platform during movement is reduced.

[0021] In summary, the present invention has the following beneficial effects: In this application, by setting up an installation base, a first limiting post, a second limiting post, and a sliding groove, the required length of the testing device's operating space is reduced.

[0027] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0028] like Figure 1-4As shown in the illustration, this application discloses a detection device for a lifting sling, including a detection platform 1, a displacement mechanism 4, a moving mechanism 9, an adjusting mechanism 10, and a limiting component 11. Two sliding seats 2 are symmetrically arranged about the center of the detection platform 1. A groove 8 is formed on the top of the detection platform 1, and positioning seats 3 are provided on the sliding seats 2. Two mounting seats 5 are slidably arranged on the top of the detection platform 1. Both mounting seats 5 are located between the two sliding seats 2. Two first limiting posts 6 are rotatably mounted on one mounting seat 5, and a second limiting post 7 is rotatably mounted on the other mounting seat 5. During the testing of the lifting sling, the lifting sling is first passed between two first limiting posts 6 and two second limiting posts 7, and both ends of the lifting sling are respectively placed on the positioning seats 3. Then, the distance between the two sets of mounting seats 5 is adjusted by the moving mechanism 9, and the first limiting posts 6 and the second limiting posts 7 move away from each other until the lifting sling is taut. Finally, the displacement mechanism 4 drives the two sliding seats 2 to move away from each other until the two sliding seats 2 move to the maximum distance. If the lifting sling does not break, it can be said that the lifting sling is qualified. By adjusting the two sets of mounting seats 5, it can adapt to the testing of lifting slings of various lengths, reducing the requirements for the length of the testing site.

[0029] A displacement mechanism 4 is mounted on the detection platform 1. The displacement mechanism 4 drives the two sliding seats 2 to move closer together or further apart. The displacement mechanism 4 includes a ring frame 41, a bidirectional threaded rod 42, limiting blocks 43, and a displacement motor 44. The ring frame 41 is fixed to the top of the detection platform 1. The bidirectional threaded rod 42 is rotatably mounted within the ring frame 41 and has two threaded grooves with opposite directions and equal pitch. The two threaded grooves are threadedly connected to the two bidirectional threaded rods 42 respectively. Two limiting blocks 43 are slidably mounted within the ring frame 41. Two limiting blocks 43 are provided, and both are threadedly connected to the bidirectional threaded rods 42. The two limiting blocks 43 are fixed to the two sliding seats 2 respectively. The displacement motor 44 is fixed to the detection platform 1 and drives the bidirectional threaded rods 42 to rotate. After the displacement motor 44 starts working, it drives the ring frame 41 to rotate. Since both limit blocks 43 are threadedly connected to the bidirectional threaded rod 42, and the two limit blocks 43 are fixed to the two sliding seats 2 respectively, the bidirectional threaded rod 42 is provided with two threaded grooves with opposite directions and equal pitch. The two threaded grooves are threadedly connected to the two bidirectional threaded rods 42 respectively, so that the two limit blocks 43, the sliding seats 2 connected to the two limit blocks 43 and the positioning seats 3 connected to the two sliding seats 2 all move away from each other until the side walls of the two limit blocks 43 move away from each other and fit against the side walls on both sides of the ring frame 41. Then it can be determined whether the lifting belt is qualified.

[0030] A moving mechanism 9 is mounted on the detection platform 1 and is used to adjust the distance between the two mounting seats 5. The moving mechanism 9 includes a threaded column 91, a gear 92, a moving motor 93, and a moving block 94. The threaded column 91 is rotatably mounted within a slide groove 8. The threaded column 91 passes through the detection platform 1 and is rotatably connected. The moving motor 93 is fixed to the detection platform 1 and drives the threaded column 91 to rotate. The gear 92 is fixedly sleeved on the threaded column 91. The moving block 94 is slidably mounted within the slide groove 8 and threadedly connected to the threaded column 91. The moving block 94 is fixed to the mounting seat 5. The number of slide grooves 8, threaded columns 91, gears 92, moving blocks 94, and mounting seats 5 are equal and their positions correspond one-to-one. The two gears 92 mesh. After the mobile motor 93 starts working, it drives the threaded column 91 connected to its output end to rotate. Due to the meshing of the two sets of gears 92, the two sets of threaded columns 91 rotate synchronously in opposite directions, causing the moving block 94 threadedly connected to the two sets of threaded columns 91 and the mounting seat 5 connected to the two moving blocks 94 to move closer or further away from each other, thereby realizing the distance between the first limiting column 6 and the second limiting column 7.

[0031] An adjustment mechanism 10 is mounted on the sliding seat 2. The adjustment mechanism 10 includes an adjustment component 101 and a clamping component 102. The number of adjustment mechanisms 10 is equal to the number of sliding seats 2, and their positions correspond one-to-one. The adjustment component 101 includes an electro-hydraulic push rod 1011 and a mounting bracket 1012. The electro-hydraulic push rod 1011 is fixed to the sliding seat 2, and the mounting bracket 1012 is fixed to the push rod end of the electro-hydraulic push rod 1011 and has an L-shaped structure. The positioning seat 3 is fixed to the mounting bracket 1012. During the process of placing the lifting sling onto the positioning seat 3, the electro-hydraulic push rod 1011 first works, causing its push rod end to extend. This causes both the mounting bracket 1012 connected to the push rod end of the electro-hydraulic push rod 1011 and the positioning seat 3 connected to the mounting bracket 1012 to move, thereby changing the distance between the two sets of positioning seats 3, making it easier for a shorter lifting sling to be placed onto the positioning seat 3.

[0032] The clamping assembly 102 is used to clamp the lifting sling. The clamping assembly 102 includes a fixed block 1021 and a movable clamping block 1022. The fixed block 1021 is fixed to the top of the sliding seat 2. The horizontal end of the mounting frame 1012 is provided with a limiting through hole 12 that slides with the fixed block 1021. The number of limiting through holes 12 is equal to the number of fixed blocks 1021 and their positions correspond one-to-one. The movable clamping block 1022 is fixed to the top of the fixed block 1021. As the two sets of positioning seats 3 approach each other, the positioning seats 3 gradually move away from the movable clamping block 1022 until the movable clamping block 1022 is in contact with the vertical section of the mounting frame 1012. At this time, the lifting sling can be put on the positioning seat 3. Then, the push rod end of the electro-hydraulic push rod 1011 retracts and resets, the two sets of positioning seats 3 move away from each other, and the positioning seats 3 move closer to the mounting seat 5. Finally, the positioning seats 3 and the mounting seat 5 clamp the lifting sling, which improves the stability of the lifting sling during testing.

[0033] Limiting components 11 are mounted on the detection platform 1. The number of limiting components 11 is equal to the number of sliding seats 2, and their positions correspond one-to-one. Each limiting component 11 includes a fixed seat 111 and a third limiting post 112. The fixed seat 111 is fixed to the top of the detection platform 1. The third limiting post 112 of the detection platform 1 is rotatably mounted on the fixed seat 111, and there are two third limiting posts 112 on the detection platform 1. After the lifting sling passes through the first limiting post 6 and the second limiting post 7 in sequence, the sidewalls at both ends of the lifting sling pass between the two third limiting posts 112 on the same side of the detection platform 1, improving the stability of the lifting sling during detection.

[0034] A plate 13 is fixed on the movable clamping block 1022, and a socket 14 is provided through the positioning seat 3 to engage with the plate 13. The number of plates 13, the number of sockets 14, and the number of movable clamping blocks 1022 are equal and their positions correspond one-to-one. As the positioning seat 3 approaches the mounting seat 5, the plate 13 is gradually inserted into the socket 14. The plate 13 limits the movement of the lifting sling, reducing the probability of the lifting sling falling off during testing.

[0035] The bottom of the sliding seat 2 is rotatably mounted with multiple rollers 15, all of which are rolledly connected to the top of the detection platform 1. This reduces the friction between the positioning seat 3 and the detection platform 1 when they move.
