Description

Technical Field

[0001] This invention relates to the field of steel rope sling inspection technology, specifically to a laser inspection device for steel rope slings. Background Technology

[0002] Steel wire rope slings are ropes made from steel wire ropes and are mainly used for hoisting, traction, tensioning, and load bearing. Steel wire rope slings are characterized by high strength, light weight, stable operation, and resistance to sudden breakage. They are widely used in industries such as steel, chemical, transportation, and ports.

[0003] In the production process of steel rope slings, the final measurement of the finished product length is a key step to ensure that it meets design specifications and safety standards. At present, many production units still generally use traditional measuring tapes for manual measurement of individual slings. This method not only relies on the experience and care of the operators, which can easily introduce human reading errors, but also has low measurement efficiency. Especially when dealing with a large number of slings, a lot of manpower and time are required to repeatedly straighten, align, and record readings, which is very time-consuming and laborious. Its measurement accuracy and repeatability sometimes cannot meet high standards. Summary of the Invention

[0004] The purpose of this invention is to provide a laser inspection device for steel wire rope slings to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a laser detection device for steel rope slings, comprising a worktable and a tensioning assembly. A driving assembly is disposed on one side of the worktable, and the tensioning assembly is disposed on the top of the worktable. The tensioning assembly includes a fixed cover. A fixed cover is disposed at one end of the top of the worktable, and a first limiting rod is slidably connected to the top of the fixed cover. A first pressure plate is fixed to the top of the first limiting rod. A buffer spring abuts against one side of the middle portion of the driving assembly, and a sliding rod abuts against one end of the buffer spring. A connecting rod is fixed to one end of the sliding rod, and a movable cover is sleeved on the outer side of one end of the connecting rod. A second limiting rod is slidably connected to the top of the movable cover, and a second pressure plate is fixed to the top of the second limiting rod. A detection plate is disposed at one end of the top of the movable cover.

[0006] Furthermore, the movable cover is slidably connected to the worktable, and the movable cover is equidistantly distributed along the top surface of the worktable.

[0007] Furthermore, the drive assembly includes a dual-axis motor, which is installed in the middle of one side of the worktable. The output end of the dual-axis motor is connected to a gear commutator, and the output end of the gear commutator is fixed with a screw. The outer side of the screw is threadedly connected to a drive seat.

[0008] Furthermore, the drive seat is slidably connected to the slide rod, and the slide rod is equidistantly distributed along the length direction of the drive seat.

[0009] Furthermore, a linear motor is mounted on the top of the drive seat, and a slide is provided above the linear motor, with a laser rangefinder fixed on the top of the slide.

[0010] Furthermore, an adjustment assembly is provided above the workbench, and the adjustment assembly includes a first limiting block. One end of the connecting rod is fixed to the first limiting block, and a compression spring is abutted inside the first limiting block. The compression spring abuts against the movable cover. A first pulley seat is provided on one side of the first limiting block, and the first pulley seat is fixedly connected to the second limiting rod.

[0011] Furthermore, drive rods are slidably connected to both sides of the worktable, and a return spring is sleeved on the outer side of one end of the drive rod. A synchronization plate is abutted on one side of the return spring, and the synchronization plate is fixedly connected to the drive rod. A second limiting block is arranged on one side of the synchronization plate, and a second pulley seat is provided on one side of the second limiting block. The second pulley seat is fixedly connected to the first limiting rod.

[0012] Furthermore, stabilizing components are provided on both sides of the slide, and the stabilizing components include limiting plates. The limiting plates are symmetrically arranged on both sides of the slide, and guide portions are provided at both ends of the limiting plates.

[0013] Furthermore, a drive plate is slidably connected inside the drive base, and a roller is rotatably connected to one end of the drive plate, while a rotating plate is rotatably connected to the other end of the drive plate. A pressure block is rotatably connected to the lower end of the rotating plate, and an anti-slip pad is provided at the bottom of the pressure block.

[0014] Furthermore, the pressure block is slidably connected to the drive seat, and the pressure block is T-shaped.

[0015] This invention provides a laser inspection device for steel wire rope slings, which has the following advantages:

[0016] 1. The present invention uses a dual-axis motor to drive the movable cover to move through a gear commutator and a screw. The design of multiple fixed covers and movable covers allows for the simultaneous installation of multiple steel rope riggings. With the help of buffer springs, independent tensioning is achieved, ensuring that samples of different lengths remain taut during testing. The alignment design of the laser rangefinder and the testing plate can quickly obtain the benchmark value and compare the deviation. The three limit rod structure effectively reduces the deformation resistance at the ends. Compared with the traditional single hook limit method, it significantly improves the straightening effect and testing accuracy of steel rope riggings, and is suitable for efficient testing of large batches of rigging.

[0017] 2. The composite design of the drive seat linkage drive rod and compression spring in this invention realizes the automatic lifting function of the limit rod, which not only facilitates the quick connection of the steel rope sling, but also enables the synchronous clamping of both ends through the gravity pressure plate. During the testing process, the height of both ends is consistent, avoiding tilting errors. When changing the sample later, the pressure plate will automatically lift and loosen the end of the steel rope sling, which greatly improves the operating efficiency.

[0018] 3. When the slide block moves, the mechanical linkage between the limiting plate and the roller automatically adjusts the frictional resistance of the pressure block on the slide rod. The measurement position is automatically locked to prevent interference from the vibration of the buffer spring. The lock is released immediately after displacement. No manual intervention is required throughout the process, ensuring the stability and reliability of the laser ranging data. Attached Figure Description

Detailed Implementation

[0027] Please see Figures 1 to 4 The present invention provides a technical solution: a laser detection device for steel wire rope slings, comprising a worktable 1 and a tensioning assembly 3. A drive assembly 2 is mounted on one side of the worktable 1. The drive assembly 2 includes a dual-axis motor 201. The dual-axis motor 201 is mounted in the middle of one side of the worktable 1, and the output end of the dual-axis motor 201 is connected to a gear commutator 202. A screw 203 is fixed to the output end of the gear commutator 202, and a drive seat 204 is threaded to the outer side of the screw 203. A linear motor 205 is mounted on the top of the drive seat 204, and a slide 206 is provided above the linear motor 205. A laser rangefinder 207 is fixed to the top of the slide 206. The tensioning assembly 3 is located on the top of the worktable 1 and includes a fixing cover 301. The fixing cover 301 is mounted on one end of the top of the worktable 1 and is fixed to the top of the worktable 1. The top of the fixed cover 301 is slidably connected to a first limiting rod 302, and the top of the first limiting rod 302 is fixed to a first pressure plate 303. A buffer spring 304 is abutted on one side of the middle part of the drive assembly 2, and one end of the buffer spring 304 abuts to a slide rod 305. The drive seat 204 is slidably connected to the slide rod 305, and the slide rod 305 is evenly distributed along the length direction of the drive seat 204. One end of the slide rod 305 is fixed to a connecting rod 306, and a movable cover 307 is sleeved on the outer side of one end of the connecting rod 306. The movable cover 307 is slidably connected to the worktable 1, and the movable cover 307 is evenly distributed along the top surface of the worktable 1. The top of the movable cover 307 is slidably connected to a second limiting rod 308, and the top of the second limiting rod 308 is fixed to a second pressure plate 309. A detection plate 310 is provided at one end of the top of the movable cover 307.

[0028] The specific operation is as follows: The dual-axis motor 201 drives the drive seat 204 to move towards the fixed cover 301 through the gear commutator 202 and the screw 203. The drive seat 204 can indirectly push the movable cover 307 to move synchronously. At this time, through the setting of multiple sets of fixed covers 301 and movable covers 307, multiple steel rope ties can be placed at the same time so that the two ends of the standard sample and multiple test samples are respectively fitted onto the outside of the first limit rod 302 and the second limit rod 308 of each set. Subsequently, the controller causes the dual-axis motor 201 to rotate in the opposite direction, and the drive seat 204 will pull the slide rod 305 through the buffer spring 304, thereby driving all the movable covers 307 to move, straightening the steel rope ties at the top of them, preventing them from slack and affecting the detection accuracy. At the same time, through the setting of multiple buffer springs 304, individual buffering can be performed, so when the sample length deviates, it can also ensure that each sample... All parts are in a tensioned state. Then, the linear motor 205 drives the slide 206 to move so that the laser rangefinder 207 is aligned with the detection plate 310. The distance between them can be quickly measured. Using this distance as a reference, when the laser rangefinder 207 moves to the next detection plate 310, the deviation value between the sample and the standard part can be detected, and the sample can be quickly judged as qualified. Thus, when inspecting a large number of rigging, multiple rigging can be quickly straightened, improving the inspection efficiency of large batches of rigging. Furthermore, the three first limit rods 302 and the second limit rods 308 limit both ends of the steel rope rigging, which helps to reduce the deformation resistance at the ends, making it easier to straighten the ends and keep the shape consistent, thereby reducing errors. Compared with the single hook limit, it can avoid the large deformation resistance at the end of the steel rope due to excessive deformation at the bend, thus making it easier to straighten and inspect.

[0029] Please see Figure 1 , Figure 3 and Figure 5 An adjustment assembly 4 is provided above the workbench 1. The adjustment assembly 4 includes a first limiting block 401. One end of the connecting rod 306 is fixed to the first limiting block 401. The inside of the first limiting block 401 abuts against a compression spring 402. The compression spring 402 abuts against the movable cover 307. A first pulley seat 403 is provided on one side of the first limiting block 401. The first pulley seat 403 is fixedly connected to a second limiting rod 308. Drive rods 404 are slidably connected to both sides of the workbench 1. A return spring 405 is sleeved on the outer side of one end of the drive rod 404. A synchronization plate 406 is abutted on one side of the return spring 405. The synchronization plate 406 is fixedly connected to the drive rod 404. A second limiting block 407 is placed on one side of the synchronization plate 406. A second pulley seat 408 is provided on one side of the second limiting block 407. The second pulley seat 408 is fixedly connected to the first limiting rod 302.

[0030] The specific operation is as follows: During the process of the drive seat 204 indirectly pushing the movable cover 307 towards the fixed cover 301, the drive seat 204 will also contact and push the drive rod 404, causing the synchronous plate 406 to drive the second limiting block 407 to squeeze the second pulley seat 408, which will cause the first limiting rod 302 to move upward, providing a larger operating space around it, thus facilitating the placement of the end of the steel rope rigging on its outside. At the same time, the compression spring 402 will also push the movable cover 307 under the limitation of the first limiting block 401, causing the first pulley seat 403 to squeeze the first limiting block 401. Similarly, the second limiting rod 308 will also move upward. Subsequently, during the return movement of the drive seat 204, since the elastic force of the buffer spring 304 is greater than that of the compression spring 402, the compression spring 402 will be compressed first, and the first limiting block 401 will move downward from the first pulley seat 403. When the first pressure plate 309 is moved away, it will press one end of the steel rope sling under the action of gravity. Then, when the first limit block 401 is in contact with the inner side of the movable cover 307, it can drive the movable cover 307 to move together. At the same time, the drive seat 204 will also separate from the drive rod 404. The return spring 405 will push the synchronous plate 406 under the limit of the worktable 1, so that the second limit block 407 separates from the second pulley seat 408. Similarly, the first pressure plate 303 can press the other end of the steel rope sling under the action of gravity, thereby ensuring that the height of the two ends is consistent during subsequent testing, avoiding the steel rope sling from tilting during tightening and affecting its testing accuracy. When replacing after testing, the above operation is repeated, so that the first pressure plate 303 and the second pressure plate 309 can automatically move up to release the steel rope sling, improving the convenience of replacement.

[0031] Please see Figure 6 and Figure 7 Stabilizing components 5 are provided on both sides of the slide 206, and the stabilizing components 5 include limiting plates 501. Limiting plates 501 are symmetrically arranged on both sides of the slide 206, and guide portions 502 are provided at both ends of the limiting plates 501. A driving plate 503 is slidably connected inside the driving seat 204, and a roller 504 is rotatably connected to one end of the driving plate 503. A rotating plate 505 is rotatably connected to the other end of the driving plate 503. A pressure block 506 is rotatably connected to the lower end of the rotating plate 505, and an anti-slip pad 507 is provided at the bottom of the pressure block 506. The pressure block 506 is slidably connected to the driving seat 204, and the pressure block 506 is T-shaped.

[0032] The specific operation is as follows: During the process of the slide block 206 driving the laser rangefinder 207 to align with the detection plate 310, the slide block 206 will also drive the limiting plate 501 to move synchronously. At this time, the guide part 502 on the limiting plate 501 guides and limits the roller 504, causing it to drive the drive plate 503 to move into the drive seat 204. Then, the rotating plate 505 applies force to the pressure block 506, increasing the frictional resistance between the anti-slip pad 507 and the slide rod 305. When the roller 504 moves to the middle of the limiting plate 501, it can exert force on the drive seat 204. The sliding rod 305 and the buffer spring 304 are locked together to prevent the sliding rod 305 from sliding within the drive seat 204 due to the vibration of the buffer spring 304 during the measurement process. This ensures the stability of the distance between the laser rangefinder 207 and the corresponding detection plate 310 during measurement. When the sliding seat 206 drives the limiting plate 501 to separate from the drive plate 503, the pressure block 506 can no longer apply much pressure, allowing the sliding rod 305 to slide within the drive seat 204. This automatically releases the limiting plate 501, requiring no additional operation and is very convenient.

[0033] In summary, this laser detection device for steel rope slings is used as follows:

[0034] First, the dual-axis motor 201 is started by the controller, which drives the drive seat 204 to move towards the fixed cover 301 via the gear commutator 202 and the screw 203. The drive seat 204 contacts and pushes the drive rod 404, causing the synchronous plate 406 to drive the second limit block 407 to press against the second pulley seat 408. This causes the first limit rod 302 to move upward, providing a larger operating space around it. At the same time, the compression spring 402 also pushes the movable cover 307 under the limitation of the first limit block 401, causing the first pulley seat 403 to press against the first limit block 401. Similarly, this also causes the second limit rod 308 to move upward. At this time, the two ends of the standard sample and multiple test samples are respectively placed on the outside of the first limit rod 302 and the second limit rod 308.

[0035] Next, the controller causes the dual-axis motor 201 to rotate in the reverse direction. During the retraction of the drive seat 204, the drive seat 204 pulls the slide rod 305 through the buffer spring 304. Since the elastic force of the buffer spring 304 is greater than that of the compression spring 402, the compression spring 402 will be compressed first. The connecting rod 306 will then pull the first limit block 401, moving it away from under the first pulley seat 403. The second pressure plate 309 will then press one end of the steel rope rigging under the action of gravity. Subsequently, when the first limit block 401 is in contact with the inner side of the movable cover 307, it can drive the movable cover 307 together. As the movement progresses, the drive seat 204 will separate from the drive rod 404. The return spring 405 will then push the synchronous plate 406 under the limit of the worktable 1, causing the second limit block 407 to separate from the second pulley seat 408. Similarly, the first pressure plate 303 can press the other end of the steel rope under the action of gravity, thereby ensuring that the height of both ends is consistent during subsequent testing, avoiding the impact on the testing accuracy due to the tilt of the steel rope when it is tightened. Furthermore, through the setting of multiple buffer springs 304, when the sample length deviates, it can also ensure that each sample is in a taut state.

[0036] Then, the linear motor 205 drives the slide 206 to move. During the process of the laser rangefinder 207 aligning with the detection plate 310, the slide 206 also drives the limiting plate 501 to move synchronously. At this time, the guide portion 502 on the limiting plate 501 guides and limits the roller 504, causing it to drive the drive plate 503 to move into the drive seat 204. This, in turn, applies force to the pressure block 506 through the rotating plate 505, increasing the frictional resistance between the anti-slip pad 507 and the slide rod 305. When the roller 504 moves to the middle of the limiting plate 501, it can exert force on the drive seat 204 and the slide rod. Locking is performed between 305 to prevent the slide bar 305 from sliding within the drive seat 204 due to the vibration of the buffer spring 304 during measurement. This ensures the stability of the distance between the laser rangefinder 207 and the corresponding detection plate 310 during measurement. The distance between them is then measured and used as a reference. Subsequently, when the slide seat 206 drives the limiting plate 501 to separate from the drive plate 503, the pressure block 506 cannot apply too much pressure, allowing the slide bar 305 to slide within the drive seat 204. This automatically releases the limit of the limiting plate 501 without additional operation, which is very convenient.

[0037] Finally, when the laser rangefinder 207 moves to the next inspection plate 310, it can detect the deviation between the sample and the standard part, quickly determine whether the sample is qualified, and thus quickly perform straightening tests on multiple rigging when inspecting a large batch of rigging, improving the inspection efficiency of large batches of rigging.
