Description

Technical Field

[0001] The present invention relates to the technical field of wire rope tensile force detection, and particularly to a wire rope tensile force detection device and a detection method thereof. Background Art

[0002] A wire rope is composed of steel wires, a rope core and grease. The manufacturing process of a wire rope is to twist steel wires that meet the requirements of mechanical properties and geometric dimensions together according to certain rules to form a spiral structure. Wire ropes are widely used in fields such as metallurgy, mining, oil and gas drilling, machinery, chemical industry, aerospace, etc. When detecting the strength of a wire rope, a wire rope tensile force detection device is used.

[0003] A Chinese patent with the publication number CN113588424B discloses a wire rope tensile force detection device. The key points of its technical solution are: a clamping cylinder is arranged at one end of a fixing hammer for limiting and fixing the wire rope. When fixing the wire rope, the rope body can be directly inserted into the clamping cylinder and then the collar is rotated to make the collar move on the clamping cylinder. During the movement, the abutting blocks are continuously squeezed, so that the two abutting blocks abut against both ends of the wire rope inserted into the clamping cylinder for fixation. At the same time, the three clamping blocks on the fixing hammer can be inserted into the clamping cavities at the side ends of the fixing grooves in a limited way to adjust the angles of the clamping cylinders on the two fixing hammers, so as to detect the tensile force of the wire rope from multiple angles.

[0004] In the above-mentioned prior art, when detecting and processing a wire rope, the two ends of the wire rope are respectively clamped and limited by using a limiting clamping method. However, the existing clamping and limiting method has a poor clamping effect, which is likely to cause the wire rope to fall off during the subsequent tensile force detection and processing of the wire rope, affecting the normal detection and processing of the wire rope, resulting in deviation of the data detected subsequently, and the overall practicability is poor. Summary of the Invention

[0005] In order to overcome the deficiencies of the prior art, the present invention provides a wire rope tensile force detection device and a detection method thereof, which can solve the technical problem that when the current wire rope tensile force detection device detects and processes a wire rope, the two ends of the wire rope are respectively clamped and limited by using a limiting clamping method, but the existing clamping and limiting method has a poor clamping effect, which is likely to cause the wire rope to fall off during the subsequent tensile force detection and processing of the wire rope, affecting the normal detection and processing of the wire rope, resulting in deviation of the data detected subsequently, and the overall practicability is poor.

[0006] To solve the above technical problems, the present invention provides the following technical solutions: A wire rope tensile force detection device, including a machine body, a controller is fixedly installed on one side of the front end of the machine body, a first motor is fixedly installed on the side wall of the machine body, and the output end of the first motor is connected to a threaded rod. A threaded sleeve is sleeved outside the threaded rod, and one side of the threaded sleeve is fixedly connected to a stretching seat. A second motor is installed inside the stretching seat, and the output end of the second motor is connected to a driving gear. One side of the driving gear is connected to a driven gear, and a clamping pipe is fixedly provided in the middle of one end of the driven gear. Meshing teeth are fixedly provided on the inner side wall of the clamping pipe. A clamping sleeve is sleeved outside one end of the clamping pipe, and a guiding block is fixedly provided on the surface of one end of the clamping sleeve. A clamping structure is fixedly provided on the top end of the stretching seat.

[0007] As a preferred technical solution of the present invention, the clamping structure includes an extension plate, a first cylinder, a lower pressing plate and a conical head. The extension plate is fixedly installed on one side of the top end of the stretching seat, and a first cylinder is fixedly installed on the top of one end of the extension plate. The output end of the first cylinder is connected to the lower pressing plate, and a conical head is fixedly installed at the bottom of the lower pressing plate.

[0008] As a preferred technical solution of the present invention, a hydraulic cylinder is fixedly provided in the middle of the inner cavity of the machine body, and the top end of the hydraulic cylinder is fixedly connected to a lifting seat. A guiding rod is fixedly installed on one side of the bottom of the lifting seat.

[0009] As a preferred technical solution of the present invention, a clamping rail is provided on the front surface of the machine body, and a positioning hole is communicated with one end of the clamping rail.

[0010] As a preferred technical solution of the present invention, a protective frame is distributed above the machine body, and a clamping bar is fixedly provided on the inner side of the bottom of the protective frame. A second cylinder is fixedly installed in the inner cavity of the clamping bar, and the output end of the second cylinder is connected to a positioning rod.

[0011] As a preferred technical solution of the present invention, the threaded rod and the threaded sleeve form a threaded connection through the threaded groove provided on its outer surface, and the threaded rod is along the vertical center line of the machine body.

[0012] As a preferred technical solution of the present invention, the driving gear and the driven gear are meshed through teeth, and the driven gear and the stretching seat are rotationally connected through a bearing seat.

[0013] As a preferred technical solution of the present invention, the clamping sleeve and the stretching seat form a sliding connection through the guiding block, and the guiding blocks are symmetrically distributed along the transverse center line of the clamping sleeve.

[0014] As a preferred technical solution of the present invention, the conical heads are equidistantly distributed along one end surface of the lower pressing plate, and one end of the conical head is provided with a conical surface.

[0015] A method for using a wire rope tensile testing device includes the following steps: Step 1: When in use, first open the protective frame and place the wire rope to be detected and processed inside the machine body. Then, pass one end of the wire rope through the hole opened on the side wall of the clamping sleeve so that it extends inside the clamping pipe. At this time, the second motor works and the driving gear connected to its output end rotates accordingly. The rotation of the driving gear and the meshing connection with the driven gear are used to realize the rotation of the clamping pipe. At this time, the rotation of the clamping pipe drives the clamping sleeve threadedly connected to its surface to move towards one side of the stretching seat, so that the meshing teeth arranged inside the clamping pipe tightly limit one end of the wire rope. Then, the first cylinder works to longitudinally push the lower pressing plate, so that it drives the conical head to move longitudinally. Combining the symmetrically arranged conical heads on both sides can further realize the tight limiting process of one end of the wire rope. Step 2: After both ends of the wire rope are limited, the protective frame is clamped and connected to the machine body through the clamping strips. Then, the first motor works and the threaded rod connected to its output end rotates accordingly. At this time, the rotation of the threaded rod drives the threaded sleeve threadedly connected to its surface to move horizontally, so as to realize the horizontal movement of the stretching seat by using the horizontal movement of the threaded sleeve. And because the threaded rod is a bidirectional threaded rod, when the threaded rod rotates, the stretching seats on both sides move towards each other, which is convenient for subsequent tensile testing of the wire rope. Step 3: During the detection process, the hydraulic cylinder works to longitudinally push the lifting seat fixedly connected to its top end, so as to realize the longitudinal movement of the lifting seat. At this time, the longitudinal movement of the lifting seat drives the guide rod to move longitudinally along the bottom of the machine body, so as to improve the stability of the longitudinal movement of the lifting seat. At the same time, the longitudinal movement of the lifting seat will longitudinally push the wire rope, so as to change the force direction of the wire rope, so that the directional tensile force of the wire rope can be detected.

[0016] Compared with the prior art, the beneficial effects that the present invention can achieve are: 1. Through structures such as the second motor, driving gear, driven gear, and clamping pipe, it is convenient to effectively clamp and limit one end of the wire rope subsequently, ensuring the stability of the wire rope during subsequent tensile testing, preventing it from falling off during the tensile testing process, with higher overall practicality and better limiting effect. When one end of the wire rope is input into the inner side of the clamping pipe, the second motor operates to drive the driving gear connected to its output end to rotate. At this time, the driving gear rotates to drive the driven gear meshed on one side to rotate accordingly. At this time, the rotation of the driven gear causes the clamping pipe to rotate. Since there is a threaded connection between the clamping pipe and the clamping sleeve, the clamping sleeve will move horizontally along the clamping pipe. When the clamping sleeve moves horizontally, it will squeeze the clamping pipe, so that multiple meshing teeth arranged on the inner side wall of the clamping pipe clamp and limit one end of the wire rope to ensure the stability of the clamping; 2. Through structures such as the first cylinder, lower pressing plate, and conical head, it is convenient to further press and limit the wire rope subsequently, which can further prevent falling off and ensure the stability of the wire rope during subsequent tensile testing. When the first cylinder operates, it will longitudinally push the lower pressing plate fixedly connected to its bottom. At this time, the longitudinal movement of the lower pressing plate drives multiple conical heads arranged at its bottom to move longitudinally accordingly. Under the action of the first cylinders on both sides, the lower pressing plates on both sides move towards each other. At this time, the movement of the lower pressing plate will cause the conical heads to also move towards each other, and then use the symmetrically arranged conical heads on both sides to further bite and limit the wire rope to ensure the stability of the wire rope; 3. Through structures such as the hydraulic cylinder, lifting seat, and guide rod, it is convenient to longitudinally move the middle part of the wire rope during subsequent testing of the wire rope, which can change the force direction of the wire rope during testing, and then improve the diversity of testing, with higher overall practicality. When the hydraulic cylinder operates, it will longitudinally push the lifting seat fixedly connected to its top. At this time, the longitudinal movement of the lifting seat drives the guide rod fixedly connected to its bottom to move longitudinally accordingly. Then, use the longitudinal movement of the guide rod to improve the stability of the lifting seat during longitudinal movement. At the same time, an arc-shaped groove is arranged in the middle of the top of the lifting seat, which is convenient to better contact the lifting seat with the wire rope subsequently and longitudinally push it.

[0019] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments. However, the following embodiments are only the preferred embodiments of the present invention, not all of them. Based on the embodiments in the embodiments, other embodiments obtained by those skilled in the art without creative efforts all fall within the protection scope of the present invention.

[0020] Please refer to Figures 1-8 As shown in the figure, the present invention is a wire rope tensile force detection device and its detection method, including a body 1, a controller 2 is fixedly installed on one side of the front end of the body 1, a first motor 3 is fixedly installed on the side wall of the body 1, and the output end of the first motor 3 is connected to a threaded rod 4. A threaded sleeve 5 is sleeved on the outer side of the threaded rod 4, and a tensile seat 6 is fixedly connected to one side of the threaded sleeve 5. A second motor 7 is installed inside the tensile seat 6, and the output end of the second motor 7 is connected to a driving gear 8. One side of the driving gear 8 is connected to a driven gear 9, and a clamping pipe 10 is fixedly provided in the middle of one end of the driven gear 9. Engaging teeth 11 are fixedly provided on the inner side wall of the clamping pipe 10. A ferrule 12 is sleeved on the outer side of one end of the clamping pipe 10, and a guide block 13 is fixedly provided on the surface of one end of the ferrule 12. A clamping structure is fixedly provided at the top of the tensile seat 6; During operation, one end of the wire rope to be detected and processed is input into the inner side of the clamping pipe 10 through the hole opened at one end of the ferrule 12. At this time, the second motor 7 operates, causing the driving gear 8 connected to its output end to rotate. Since the driving gear 8 and the driven gear 9 are meshed, when the driving gear 8 rotates, the driven gear 9 will rotate accordingly. At this time, the rotation of the driven gear 9 drives the clamping pipe 10 to rotate. Since the clamping pipe 10 is threadedly connected to the ferrule 12 through the threads provided on its surface, when the clamping pipe 10 rotates, the ferrule 12 will move horizontally towards the inner side of the stretching seat 6. Then, under the extrusion of the ferrule 12, the separated parts of the clamping pipe 10 will gradually gather. Subsequently, a plurality of meshing teeth 11 equidistantly arranged on the inner side wall of the clamping pipe 10 are used to bite one end of the wire rope, so as to improve the effective limiting treatment of one end of the wire rope and ensure that the wire rope will not fall off during the subsequent tensile test. During the subsequent test, the first motor 3 operates, causing the threaded rod 4 connected to its output end to rotate. Since the threaded rod 4 is a double-threaded screw, the rotation of the threaded rod 4 can be used to make the threaded sleeves 5 symmetrically arranged on both sides of the machine body 1 move horizontally, and then the horizontal movement of the threaded sleeves 5 is used to realize the opposite movement of the stretching seats 6 on both sides, which is convenient for the subsequent tensile test of the wire rope.

[0021] The clamping structure includes an extension plate 14, a first cylinder 15, a lower pressing plate 16 and a tapered head 17. The extension plate 14 is fixedly installed on one side of the top of the stretching seat 6, and a first cylinder 15 is fixedly installed at the top of one end of the extension plate 14. The output end of the first cylinder 15 is connected to the lower pressing plate 16, and a tapered head 17 is fixedly installed at the bottom of the lower pressing plate 16. During operation, when one end of the wire rope is initially clamped, the first cylinder 15 operates to longitudinally push the lower pressing plate 16 fixedly connected to its bottom. At this time, the longitudinal movement of the lower pressing plate 16 drives a plurality of tapered heads 17 equidistantly distributed at its bottom to move longitudinally accordingly. Then, by combining the tapered heads 17 moving towards each other on both sides, the clamping and limiting treatment of one end of the wire rope can be further realized, ensuring the stability of the wire rope during the subsequent tensile test.

[0022] A hydraulic cylinder 18 is fixedly installed in the middle of the inner cavity of the machine body 1, and the top of the hydraulic cylinder 18 is fixedly connected to a lifting seat 19. A guide rod 20 is fixedly installed on one side of the bottom of the lifting seat 19. During operation, the hydraulic cylinder 18 operates to longitudinally push the lifting seat 19 fixedly connected to its top, and then the longitudinal movement of the lifting seat 19 is used to drive the wire rope to move longitudinally, which is convenient for adjusting the force direction of the wire rope during the test subsequently, and then better performing the tensile test on the wire rope. At the same time, when the lifting seat 19 moves longitudinally, it will drive the guide rod 20 to move longitudinally along the machine body 1, so as to improve the stability of the lifting seat 19 during the longitudinal movement.

[0023] A clamping rail 21 is provided on the front end surface of the machine body 1, and a positioning hole 22 is communicated with one end of the clamping rail 21; During operation, since the clamping rails 21 are symmetrically distributed along the vertical center line of the machine body 1, when the protection frame 23 slides along the clamping rails 21, the preliminary connection between the protection frame 23 and the machine body 1 can be realized. Subsequently, when the positioning rod 26 is input into the inner side of the positioning hole 22, the stable connection between the protection frame 23 and the machine body 1 can be realized.

[0024] A protection frame 23 is distributed above the machine body 1, and a clamping strip 24 is fixedly installed on the inner side of the bottom of the protection frame 23. A second air cylinder 25 is fixedly installed in the inner cavity of the clamping strip 24, and a positioning rod 26 is connected to the output end of the second air cylinder 25; During operation, the protection frame 23 is slidably connected to the clamping rail 21 provided on the surface of one end of the machine body 1 through the clamping strip 24 fixedly installed on the inner side wall of its bottom. When the clamping strip 24 is completely engaged with the clamping rail 21, the second air cylinder 25 works to push the positioning rod 26 connected to its output end, and then one end of the positioning rod 26 is input into the inner side of the positioning hole 22, so as to realize the quick connection between the protection frame 23 and the machine body 1, which is convenient for subsequent debris to fly when the steel wire rope breaks, reducing the existence of potential safety hazards.

[0025] The threaded rod 4 is threadedly connected to the threaded sleeve 5 through the thread groove provided on its outer surface, and the threaded rod 4 is along the vertical center line of the machine body 1; During operation, the first motor 3 works to drive the threaded rod 4 connected to its output end to rotate, and then the threaded rod 4 rotates to drive the threaded sleeve 5 threadedly connected to its outer surface to move horizontally, which is convenient for subsequent realizing the horizontal movement of the stretching seat 6 by using the horizontal movement of the threaded sleeve 5.

[0026] The driving gear 8 is meshed with the driven gear 9 through teeth, and the driven gear 9 is rotatably connected to the stretching seat 6 through a bearing seat; During operation, when the driving gear 8 rotates under the rotation action of the second motor 7, the driven gear 9 meshed with one side of it will move synchronously, which is convenient for subsequent realizing the rotation of the clamping pipe 10 by using the rotation of the driven gear 9.

[0027] The clamping sleeve 12 is slidably connected to the stretching seat 6 through the guide block 13, and the guide blocks 13 are symmetrically distributed along the horizontal center line of the clamping sleeve 12; During operation, since the guide blocks 13 are symmetrically distributed along the horizontal center line of the clamping sleeve 12, when the clamping sleeve 12 moves horizontally, it will drive the guide blocks 13 to slide along the slot openings provided on the surfaces of both ends of the stretching seat 6, so as to improve the stability of the clamping sleeve 12 during the horizontal movement process.

[0028] The conical heads 17 are evenly distributed along one end surface of the lower pressing plate 16, and one end of each conical head 17 is provided with a conical surface; During operation, since the conical heads 17 are evenly distributed along one end surface of the lower pressing plate 16 and the lower pressing plates 16 are symmetrically distributed, when the two side lower pressing plates 16 move longitudinally to drive the conical heads 17 to move towards each other, the conical heads 17 can be used to perform biting and limiting treatment on one end of the steel wire rope, ensuring the stability of the steel wire rope during subsequent tensile testing.

[0029] Specific working principle: One end of the wire rope to be detected and processed is input into the inner side of the clamping pipe 10 through the hole opened at one end of the ferrule 12. At this time, the second motor 7 works, and the driving gear 8 connected to its output end rotates accordingly. Since the driving gear 8 and the driven gear 9 are meshed with each other, when the driving gear 8 rotates, the driven gear 9 will rotate accordingly. At this time, the rotation of the driven gear 9 drives the clamping pipe 10 to rotate accordingly. Since the clamping pipe 10 is threadedly connected to the ferrule 12 through the threads provided on its surface, when the clamping pipe 10 rotates, the ferrule 12 will move horizontally towards the inner side of the stretching seat 6. Then, under the extrusion of the ferrule 12, the separated parts of the clamping pipe 10 will gradually gather. Subsequently, a plurality of meshing teeth 11 arranged at equal intervals on the inner side wall of the clamping pipe 10 are used to bite one end of the wire rope, so as to improve the effective limiting treatment of one end of the wire rope and ensure that the wire rope will not fall off during the subsequent tensile test. When one end of the wire rope is initially clamped, the first cylinder 15 works to longitudinally push the lower pressing plate 16 fixedly connected to its bottom. At this time, the longitudinal movement of the lower pressing plate 16 drives a plurality of tapered heads 17 evenly distributed at its bottom to move longitudinally accordingly. Then, in combination with the tapered heads 17 moving towards each other on both sides, the clamping and limiting treatment of one end of the wire rope can be further realized, ensuring the stability of the wire rope during the subsequent tensile test. After the two ends of the wire rope are fixed, the protective frame 23 is slidably connected to the clamping rail 21 opened on the surface of one end of the machine body 1 through the clamping strip 24 fixedly installed on the inner side wall of its bottom. When the clamping strip 24 is completely engaged with the clamping rail 21, the second cylinder 25 works to push the positioning rod 26 connected to its output end, and then one end of the positioning rod 26 is input into the positioning hole 22, so as to realize the rapid connection between the protective frame 23 and the machine body 1, which is convenient for debris to fly when the wire rope breaks during the subsequent test, reducing the existence of potential safety hazards. During the subsequent test, the first motor 3 works to drive the threaded rod 4 connected to its output end to rotate. Since the threaded rod 4 is a double-threaded rod, the rotation of the threaded rod 4 can be used to make the threaded sleeves 5 symmetrically arranged on both sides of the machine body 1 move horizontally accordingly. Then, the horizontal movement of the threaded sleeves 5 is used to realize the opposite movement of the stretching seats 6 on both sides, which is convenient for the subsequent tensile test of the wire rope. When the hydraulic cylinder 18 works, it will longitudinally push the lifting seat 19 fixedly connected to its top. Then, the longitudinal movement of the lifting seat 19 is used to drive the wire rope to move longitudinally, which is convenient for adjusting the force direction of the wire rope during the test subsequently, and thus better for the tensile test of the wire rope. At the same time, when the lifting seat 19 moves longitudinally, it will drive the guide rod 20 to move longitudinally along the machine body 1, so as to improve the stability of the lifting seat 19 during the longitudinal movement process.
