Description

Technical Field

[0001] This invention belongs to the field of metal wire rope and its products manufacturing technology, specifically a stainless steel wire rope testing device. Background Technology

[0002] Stainless steel wire rope is a high-strength rope made of multiple strands of stainless steel wire. It has excellent corrosion resistance, high strength, and long-term durability, and is widely used in many fields. During the manufacturing process of stainless steel wire rope, it is necessary to test the corrosion resistance of the stainless steel wire rope through a testing device to determine whether the stainless steel wire rope is qualified. Therefore, the corrosion resistance testing of stainless steel wire rope is an indispensable part of the production and processing, and the testing device is an essential piece of equipment in the manufacturing process of stainless steel wire rope.

[0003] Patent CN117686412A discloses a test device and method for testing the alkali resistance of steel wire ropes, including a base, support legs, a top frame, a water tank, an adjustment mechanism, a pressure application mechanism, and a controller. In this solution, a telescopic cylinder is used to push a pressure sensor downward. The downward movement of the pressure sensor can drive a gate to move downward. Then, a drive electric motor is used to tighten the steel rope. The pressure provided by the telescopic cylinder drives the gate to squeeze the steel rope, thus testing the overall tensile strength of the steel rope. At this time, the tensile strength of the steel rope can be quickly observed by observing the pressure value detected by the pressure sensor. Compared with the method of observing corrosion with the naked eye, this device can directly test the tensile strength of the steel rope under alkaline corrosion.

[0004] Stainless steel wire ropes are used in marine environments. In actual use, stainless steel wire ropes are generally immersed in seawater, and the stainless steel wires are subjected to tensile forces. Therefore, the stainless steel wires are simultaneously subjected to the corrosive force of seawater and the tensile force exerted by the external environment. In the above-mentioned solutions, the wire rope is first placed in an alkaline solution for corrosion resistance testing, and then the tensile strength test is performed after the alkaline solution on the wire rope is dried. Therefore, the corrosion resistance test and the tensile strength test are carried out separately, which differs from the actual use environment and reduces the accuracy of the test. To address this, the present invention provides a stainless steel wire rope testing device. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0006] The technical solution adopted by the present invention to solve its technical problem is as follows: The stainless steel wire rope detection device of the present invention includes a frame, a liquid storage tank is installed on the frame, clamping mechanisms for fixing the ends of steel wire ropes are symmetrically arranged on both sides of the upper end of the liquid storage tank, an L-shaped support frame is arranged between the two sets of clamping mechanisms, a cylinder is fixedly installed on the L-shaped support frame, a pressure sensor is installed at the output end of the cylinder, a mounting frame is connected to the lower end of the pressure sensor, a gate plate is installed at the lower end of the mounting frame, the clamping mechanism includes two sets of fixed columns, the fixed columns are fixedly installed on the frame, a linear bearing is slidably fitted on the fixed columns, the linear bearing is fixedly installed on a movable plate, a first spring is arranged below the movable plate, a first clamping plate is fixedly connected to one end of the movable plate, a bolt is rotatably installed on the first clamping plate, a second clamping plate is screwed to the bolt, an opening for the steel wire rope to pass through is provided on the upper end face of the liquid storage tank, two sets of through holes are opened on the second clamping plate, the through holes are slidably connected to guide columns, and one end of the guide columns is fixedly connected to the first clamping plate;

[0007] This method involves immersing the wire rope in an alkaline solution while simultaneously bending and compressing it. This allows for simultaneous corrosion resistance and tensile strength testing, which not only better reflects the actual operating environment but also improves testing accuracy.

[0008] Preferably, the mounting frame includes a main frame body, a pressure sensor fixedly connected to the upper end of the main frame body, a rotating shaft rotatably mounted on the main frame body, a gate plate fitted on the rotating shaft, a limit rod movably mounted above one end of the rotating shaft, a second spring fitted on the limit rod, a lever plate fixedly mounted at the upper end of the limit rod, the limit rod movably inserted into one side of the main frame body, four sets of limit holes equally spaced at one end of the rotating shaft, and a set of limit holes inserted into the lower end of the limit rod;

[0009] The gate is turned, causing the swivel shaft to rotate 90 degrees, positioning the next set of limit holes directly below the limit rod. Releasing the gate causes the limit rod to automatically insert into the next set of limit holes under the rebound force of the second spring, thus limiting the swivel shaft. This changes the contact position between the gate and the wire rope, extending the gate's service life, reducing the frequency of gate replacement, and saving material resources.

[0010] Preferably, the mounting frame further includes a pre-positioning mechanism, which includes a rectangular shaft, one end of which is fixedly connected to the other end of a screw-in shaft, a chuck movably mounted on the rectangular shaft, a third spring mounted on the rectangular shaft, four sets of slots equally spaced on the outer ring of the chuck, the four sets of slots respectively engaging four sets of blocks, the four sets of blocks being fixedly mounted on the other side of the main frame, one end of the third spring being fixedly connected to the chuck, and the other end of the third spring being fixedly connected to the main frame.

[0011] The engagement between the slot and the block causes the rotating shaft to rotate exactly 90 degrees, and the next set of limit holes is located directly below the limit rod. This eliminates the need for staff to manually check the positions of the limit rod and the limit holes, improving the efficiency of staff in changing the contact position between the gate and the wire rope.

[0012] Preferably, the mounting frame is symmetrically provided with opening and closing mechanisms for sealing the opening on both the front and rear sides. The opening and closing mechanism includes a cover plate located on the opening, a receiving plate fixedly installed on the cover plate, a guide groove opened on the receiving plate, the guide groove being composed of an oblique groove and a vertical groove, a pin set in the guide groove, the pin being fixedly installed on the receiving frame, one end of the receiving frame being fixedly connected to the main frame, and two sets of guide grooves symmetrically opened on the frame, with the two ends of the cover plate being slidably connected to the two sets of guide grooves respectively.

[0013] The main frame on the mounting bracket moves the receiving frame downwards. The receiving frame drives the pin to slide along the inclined groove first. Guided by the inclined groove, the two sets of cover plates move in opposite directions along the corresponding guide grooves until the pin slides to the intersection of the inclined groove and the vertical groove. At this point, the opening is fully opened. As the pin continues to move downwards along the vertical groove, the wire rope enters the liquid storage tank through the opening. Conversely, when the receiving frame returns to the initial position, the two sets of cover plates merge again and close the opening, thereby preventing the alkaline solution from evaporating from the opening and achieving the purpose of protecting the surrounding environment and conserving resources.

[0014] The beneficial effects of this invention are as follows:

[0015] 1. This method involves immersing the wire rope in an alkaline solution and simultaneously bending and compressing the wire rope while it is immersed in the alkaline solution. This allows for simultaneous corrosion resistance and tensile strength testing, which not only better reflects the actual operating environment but also improves the accuracy of the testing.

[0016] 2. Move the lever upwards. The lever causes the limit rod to disengage from the current limit hole, and the limit rod compresses the second spring, releasing the limit on the rotary joint shaft. Then, rotate the gate. The gate rotates the rectangular shaft through the rotary joint shaft, which in turn rotates the chuck. This causes the chuck's groove to be pressed by the chuck block. The chuck will slide along the rectangular shaft away from the chuck block, and the chuck will stretch the third spring until, under the rebound force of the third spring, the chuck's groove engages with the chuck block again. Under the engagement of the groove and the chuck block, the rotary joint shaft rotates exactly 90 degrees, and the next set of limit holes is directly below the limit rod. Release the lever. Under the rebound force of the second spring, the limit rod automatically inserts into the next set of limit holes, achieving the limit on the rotary joint shaft. This changes the contact position between the gate and the wire rope, improving the gate's service life, reducing the frequency of gate replacement, and saving material resources.

[0017] 3. When the mounting frame moves downward, the main frame on the mounting frame drives the receiving frame downward. The receiving frame drives the pin to slide along the inclined groove first. Guided by the inclined groove, the two sets of cover plates move in opposite directions along the corresponding guide grooves until the pin slides to the intersection of the inclined groove and the vertical groove. At this time, the opening is fully opened. As the pin continues to move downward along the vertical groove, the wire rope enters the liquid storage tank through the opening. Conversely, when the receiving frame returns to the initial position, the two sets of cover plates merge again and close the opening, thereby preventing the alkaline solution from evaporating from the opening, achieving the purpose of protecting the surrounding environment and saving resources.

[0028] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0029] Example 1: As Figure 1 and Figure 2 As shown in the embodiment of the present invention, a stainless steel wire rope testing device includes a frame 1, on which a liquid storage tank 2 is mounted. Clamping mechanisms 3 for fixing the ends of steel wire ropes 9 are symmetrically arranged on both sides of the upper end of the liquid storage tank 2. An L-shaped support frame 4 is arranged between the two clamping mechanisms 3. A cylinder 5 is fixedly mounted on the L-shaped support frame 4. A pressure sensor 51 is installed at the output end of the cylinder 5. A mounting frame 6 is connected to the lower end of the pressure sensor 51. A gate plate 7 is installed at the lower end of the mounting frame 6. The clamping mechanism 3 includes two sets of fixing columns 301, which are fixedly mounted on the frame 1 and slidably fitted onto the frame 1. A linear bearing 302 is fixedly mounted on a movable plate 303. A first spring 304 is provided below the movable plate 303. A first clamping plate 305 is fixedly connected to one end of the movable plate 303. A bolt 306 is rotatably mounted on the first clamping plate 305. A second clamping plate 307 is screwed onto the bolt 306. An opening 201 for the passage of a wire rope 9 is provided on the upper surface of the liquid storage tank 2. Two sets of through holes 3071 are provided on the second clamping plate 307. The through holes 3071 are slidably connected to a guide post 3072. One end of the guide post 3072 is fixedly connected to the first clamping plate 305.

[0030] Specifically, all components of this device have undergone anti-corrosion treatment. The storage tank 2 contains an alkaline solution. The pressure sensor 51 is electrically connected to an external controller. The length of the detection wire rope 9 is equal to the distance between the two sets of clamping mechanisms 3. Initially, the mounting bracket 6 and the gate 7 are located directly above the opening 201. When it is necessary to detect the wire rope 9, one end of the wire rope 9 is placed between the first clamping plate 305 and the second clamping plate 307 of the clamping mechanism 3. Then, the bolt 306 is turned with a hex wrench to move the second clamping plate 305. 7. Move along the guide post 3072 towards the first clamping plate 305 until one end of the wire rope 9 is clamped between the first clamping plate 305 and the second clamping plate 307, thus fixing one end of the wire rope 9 to a set of clamping mechanisms 3. Then, through the same operation, fix the other end of the wire rope 9 to another set of clamping mechanisms 3. Next, start the cylinder 5. The output end of the cylinder 5 pushes the pressure sensor 51, along with the mounting bracket 6 and the gate 7, to move downwards, causing the gate 7 to press against the middle of the wire rope 9. The wire rope 9 pulls the clamping mechanisms 3 at both ends, causing the live wire rope 9 to move downwards. The movable plate 303, the first clamping plate 305, and the second clamping plate 307 move downwards along the wire rope 9. The movable plate 303 slides along the fixed column 301 via the linear bearing 302, compressing the first spring 304. The wire rope 9 then enters the storage tank 2 through the opening 201, coming into contact with the alkaline solution. When the movable plate 303 can no longer slide along the fixed column 301, the wire rope 9 is completely submerged in the alkaline solution. At this point, the cylinder 5 continues to press down, and the pressure sensor 51 detects and responds to the feedback. The pressure value is maintained for a certain period of time to detect the tensile strength of the wire rope 9 in the alkaline solution. After the test is completed, the cylinder 5 is withdrawn, and under the rebound force of the first spring 304, the wire rope 9 is pulled out of the liquid storage tank 2 along with the gate 7 until it returns to the initial position. Compared with the existing technology, this solution immerses the wire rope 9 in the alkaline solution and simultaneously bends and squeezes the wire rope 9 immersed in the alkaline solution, so that corrosion resistance testing and tensile strength testing are carried out at the same time. This not only more closely reflects the actual operating environment, but also improves the accuracy of the test.

[0031] like Figures 3 to 5 As shown, the mounting frame 6 includes a main frame 601, with a pressure sensor 51 fixedly connected to the upper end of the main frame 601, a rotating shaft 602 rotatably mounted on the main frame 601, a gate 7 fitted onto the rotating shaft 602, a limit rod 603 movably mounted above one end of the rotating shaft 602, a second spring 604 fitted onto the limit rod 603, and a lever 605 fixedly mounted at the upper end of the limit rod 603. The limit rod 603 is movably inserted into one side of the main frame 601, and four sets of limit holes 6021 are equally spaced at one end of the rotating shaft 602. One set of limit holes 6021 is inserted into the lower end of the limit rod 603.

[0032] Specifically, the pressure of the gate plate 7 on the wire rope 9 generates friction, which damages the anti-corrosion coating on the gate plate 7. After long-term use, the anti-corrosion coating in the contact area between the gate plate 7 and the wire rope 9 will be completely destroyed. If the gate plate 7 continues to be used, the wear in the contact area between the gate plate 7 and the wire rope 9 will increase significantly, affecting the accuracy of detection. Therefore, the gate plate 7 needs to be replaced. However, replacing the entire gate plate 7 is time-consuming, labor-intensive, and wasteful of materials. In the initial state, the limit rod 603 is inserted into the limit hole 6021. When a large area of ​​wear occurs in the contact area between the gate plate 7 and the wire rope 9, the lever 605 is moved upwards. The lever 605 drives the limiting rod 603 to disengage from the current limiting hole 6021, and the limiting rod 603 compresses the second spring 604, releasing the limiting of the rotating shaft 602. Then, the lever 7 rotates, causing the rotating shaft 602 to rotate 90 degrees, so that the next set of limiting holes 6021 is directly below the limiting rod 603. The lever 605 is released, and under the rebound force of the second spring 604, the limiting rod 603 automatically inserts into the next set of limiting holes 6021, realizing the limiting of the rotating shaft 602. This changes the contact position between the lever 7 and the wire rope 9, improves the service life of the lever 7, reduces the replacement frequency of the lever 7, and achieves the purpose of saving material resources.

[0033] Furthermore, the mounting frame 6 also includes a pre-positioning mechanism 606, which includes a rectangular shaft 6061. One end of the rectangular shaft 6061 is fixedly connected to the other end of the screw-in shaft 602. A chuck 6062 is movably mounted on the rectangular shaft 6061. A third spring 6064 is mounted on the rectangular shaft 6061. Four sets of slots 6065 are equally spaced on the outer ring of the chuck 6062. The four sets of slots 6065 respectively engage four sets of blocks 6063. The four sets of blocks 6063 are all fixedly mounted on the other side of the main frame 601. One end of the third spring 6064 is fixedly connected to the chuck 6062, and the other end of the third spring 6064 is fixedly connected to the main frame 601.

[0034] Specifically, when the aforementioned gate 7 is rotated, the gate 7 drives the rectangular shaft 6061 to rotate via the rotating shaft 602. The rectangular shaft 6061 drives the chuck 6062 to rotate, causing the slot 6065 on the chuck 6062 to be squeezed by the locking block 6063. The chuck 6062 will slide along the rectangular shaft 6061 away from the locking block 6063, and the chuck 6062 stretches the third spring 6064 until the third spring 6064, under the action of the rebound force, causes the slot 6065 on the chuck 6062 to engage with the locking block 6063 again. Under the engagement action of the slot 6065 and the locking block 6063, the rotating shaft 602 rotates exactly 90 degrees, and the next set of limit holes 6021 is located directly below the limit rod 603. There is no need for the staff to manually check the position of the limit rod 603 and the limit hole 6021, which improves the efficiency of the staff to change the contact position between the gate 7 and the wire rope 9.

[0035] Example 2: Figures 6 to 8 As shown in the comparative embodiment one, another embodiment of the present invention is as follows: the mounting frame 6 is symmetrically provided with opening and closing mechanisms 8 for sealing the opening 201 on both the front and rear sides. The opening and closing mechanism 8 includes a cover plate 801, which is located on the opening 201. A receiving plate 802 is fixedly installed on the cover plate 801. A guide groove 803 is opened on the receiving plate 802. The guide groove 803 is composed of an oblique groove 8031 ​​and a vertical groove 8032. A pin 804 is set in the guide groove 803. The pin 804 is fixedly installed on the receiving frame 805. One end of the receiving frame 805 is fixedly connected to the main frame 601. Two sets of guide grooves 101 are symmetrically opened on the frame 1. The two ends of the cover plate 801 are slidably connected to the two sets of guide grooves 101 respectively.

[0036] Specifically, because the alkaline solution is volatile, the opening 201 remains open whether in use or not, causing the alkaline solution to evaporate from it. This not only pollutes the surrounding environment but also wastes the solution. Initially, the two sets of cover plates 801 are closed, sealing the opening 201. When the mounting frame 6 moves downward, the main frame 601 on the mounting frame 6 drives the receiving frame 805 downward. The receiving frame 805 then drives the pin 804 to slide along the inclined groove 8031, guiding the pin through the inclined groove 8031. The two sets of cover plates 801 move backward along the corresponding guide grooves 101 until the pin 804 slides to the intersection of the inclined groove 8031 ​​and the vertical groove 8032. At this time, the opening 201 is fully opened. As the pin 804 continues to move downward along the vertical groove 8032, the wire rope 9 enters the liquid storage tank 2 through the opening 201. Conversely, when the receiving frame 805 returns to the initial position, the two sets of cover plates 801 merge again and close the opening 201, thereby preventing the alkaline solution from evaporating from the opening 201, achieving the purpose of protecting the surrounding environment and saving resources.

[0037] Working principle: One end of the wire rope 9 is placed between the first clamping plate 305 and the second clamping plate 307 of a set of clamping mechanisms 3. Then, the bolt 306 is turned with a hex wrench, causing the second clamping plate 307 to move along the guide post 3072 towards the first clamping plate 305 until one end of the wire rope 9 is clamped between the first clamping plate 305 and the second clamping plate 307, thus fixing one end of the wire rope 9 to a set of clamping mechanisms 3. Then, the other end of the wire rope 9 is fixed to another set of clamping mechanisms 3 through the same operation. Then, the cylinder 5 is activated. The output end of the cylinder 5 pushes the pressure sensor 51, along with the mounting bracket 6 and the gate plate 7, to move downwards, causing the gate plate 7 to press against the middle of the wire rope 9. The wire rope 9 pulls the clamping mechanisms 3 at both ends, causing the movable plate 303 and the first clamping plate 307 to move downwards. 05. The second clamping plate 307 moves downward with the wire rope 9, and the movable plate 303 slides along the fixed column 301 through the linear bearing 302. The movable plate 303 compresses the first spring 304, and the wire rope 9 will enter the storage tank 2 through the opening 201. The wire rope 9 will come into contact with the alkaline solution. When the movable plate 303 can no longer slide along the fixed column 301, the wire rope 9 will be completely submerged in the alkaline solution. At this time, the cylinder 5 will continue to press down, and the pressure sensor 51 will detect the feedback pressure value. The pressure will be maintained for a certain period of time to detect the tensile strength of the wire rope 9 in the alkaline solution. After the test is completed, the cylinder 5 will be withdrawn. Under the action of the rebound force of the first spring 304, the wire rope 9 will exit the storage tank 2 with the gate 7 until it returns to the initial position.

[0038] When a large area of ​​wear occurs in the contact area between the gate plate 7 and the wire rope 9, the lever plate 605 is moved upwards. The lever plate 605 causes the limit rod 603 to disengage from the current limit hole 6021, and the limit rod 603 compresses the second spring 604, releasing the limit on the rotary joint shaft 602. Then, the gate plate 7 is rotated, and the gate plate 7 drives the rectangular shaft 6061 to rotate through the rotary joint shaft 602. The rectangular shaft 6061 drives the chuck 6062 to rotate, causing the slot 6065 on the chuck 6062 to be squeezed by the locking block 6063. The chuck 6062 will slide along the rectangular shaft 6061 away from the locking block 6063, and the chuck 6062 will stretch the third spring 6064 until... Under the rebound force of the third spring 6064, the slot 6065 on the chuck 6062 engages with the block 6063 again. Under the engagement of the slot 6065 and the block 6063, the rotary shaft 602 rotates exactly 90 degrees. The next set of limiting holes 6021 is located directly below the limiting rod 603. When the lever 605 is released, under the rebound force of the second spring 604, the limiting rod 603 automatically inserts into the next set of limiting holes 6021, thereby limiting the rotary shaft 602 and changing the contact position between the gate 7 and the wire rope 9.

[0039] When the mounting frame 6 moves downward, the main frame 601 on the mounting frame 6 drives the receiving frame 805 to move downward. The receiving frame 805 drives the pin 804 to slide along the inclined groove 8031 ​​first. Under the guidance of the inclined groove 8031, the two sets of cover plates 801 move in opposite directions along the corresponding guide groove 101 until the pin 804 slides to the intersection of the inclined groove 8031 ​​and the vertical groove 8032. At this time, the opening 201 is fully opened. As the pin 804 continues to move downward along the vertical groove 8032, the wire rope 9 enters the liquid storage tank 2 through the opening 201. Conversely, when the receiving frame 805 returns to the initial position, the two sets of cover plates 801 merge again and close the opening 201.
