Description

Technical Field

[0002] Chemical fiber rope net is a mesh product made of chemical fiber. It has the characteristics of light weight, durability, corrosion resistance, and strong weather resistance. It is often used in transportation, construction, agriculture, fisheries, outdoor sports and other fields. However, chemical fiber rope nets in different usage scenarios require different tensile properties. Therefore, it is necessary to test the tensile properties of chemical fiber rope nets to ensure that they can meet the usage scenarios.

[0003] Products in the prior art generally use a stretching machine to monitor their tensile properties. The working principle of the stretching machine is mainly to apply external force to the test product to cause it to produce strain, and then various sensors collect the tensile deformation and force of the product during the test process.

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0022] like Figures 1 to 5As shown, a tensile performance testing device for a chemical fiber rope net according to an embodiment of the present invention comprises a base 1; a fixed seat 2 is fixedly connected to one side of the top surface of the base 1; a traction seat 3 is slidably connected to the side of the top surface of the base 1 away from the fixed seat 2, and the traction seat 3 is driven by a hydraulic system; a connecting seat 4 is installed on the surface of the side where the fixed seat 2 and the traction seat 3 are close to each other; a tension sensor is installed between the connecting seat 4 located at the traction seat 3 and the traction seat 3, and the connecting seat 4 located at the fixed seat 2 is fixedly connected to the fixed seat 2; a clamping assembly is installed on the side where the two connecting seats 4 are close to each other; The clamping assembly includes a lower clamping plate 5 and an upper clamping plate 6; a driving assembly is installed at the upper clamping plate 6; the driving assembly is used to drive the upper clamping plate 6 to press the lower clamping plate 5; the lower clamping plate 5 is fixedly connected to the bottom of the connecting seat 4; the upper clamping plate 6 is slidably connected to the surface of the connecting seat 4; a mounting groove 7 is provided on the side where the upper clamping plate 6 and the lower clamping plate 5 are close to each other; a scissor-type telescopic frame 8 is provided in the mounting groove 7, and one end of the scissor-type telescopic frame 8 is fixedly connected to the bottom of the mounting groove 7; the middle hinge point of the scissor-type telescopic frame 8 is fixedly connected with an extrusion block 9; during operation, in order to ensure that the tested sample can be better To reflect the tensile performance of the entire chemical fiber rope net, the embodiment of the present invention can be used. First, the user needs to cut off a part of the chemical fiber rope net with a complete woven structure and use it as a sample. Then, the user moves the upper clamp 6 to move it away from the lower clamp 5. Then, the user pulls the scissor-type telescopic frame 8 in the installation groove 7, so that it drives the extrusion blocks 9 on its surface to move synchronously and keeps the spacing between each extrusion block 9 equal, thereby adapting to the knot spacing of different sample chemical fiber rope nets. After that, the user can place the knot of the chemical fiber rope net on the extrusion block 9 at the lower clamp 5, and then the user drives the connection The driving assembly at the seat 4 presses the upper clamping plate 6 toward the lower clamping plate 5 through the driving assembly, so that the extrusion blocks 9 at the upper clamping plate 6 and the lower clamping plate 5 clamp the knot of the sample. When the knots at both ends of the sample are clamped by the upper clamping plate 6 and the lower clamping plate 5 at the fixed seat 2 and the traction seat 3 respectively, the user starts the hydraulic system to drive the traction seat 3 away from the fixed seat 2, thereby stretching the sample, and obtains specific data through the tension sensor at the traction seat 3, and then obtains the tensile properties of the sample. Since the sample has the same weaving structure as the complete chemical fiber rope net, it can better reflect the tensile properties of the entire chemical fiber rope net.

[0023] like Figures 4 to 5As shown, the bottom of the mounting groove 7 is provided with a rotation groove 10; a threaded rod 11 is rotatably connected in the rotation groove 10; a slider 12 is threadedly connected to the surface of the threaded rod 11; the slider 12 is fixedly connected to the movable end of the scissor-type telescopic frame 8; the same end of the upper clamping plate 6 and the lower clamping plate 5 is rotatably connected to a connecting rod 13; the connecting rod 13 is fixedly connected to the end of the threaded rod 11, and the end of the connecting rod 13 away from the threaded rod 11 is a hexagonal prism; during operation, when the user needs to adjust the scissor-type telescopic frame 8, the user can screw the connecting rod 13, and the connecting rod 13 drives the threaded rod 11 to move. The rod 11 rotates, and the rotating threaded rod 11 drives the slider 12 thereon to slide, and the slider 12 is fixed to the end of the scissors-type telescopic frame 8 that is not fixed to the mounting groove 7, so the slider 12 can pull the scissors-type telescopic frame 8 to extend and contract, thereby realizing the adjustment of the scissors-type telescopic frame 8. At the same time, the slider 12 will only move when the threaded rod 11 rotates, so the threaded cooperation between the threaded rod 11 and the slider 12 can also play a locking role, thereby preventing the user from adjusting the spacing of the extrusion blocks 9 on the scissors-type telescopic frame 8 and causing the scissors-type telescopic frame 8 to extend or retract due to shaking or accidental touch.

[0024] like Figures 4 to 6 As shown, the ends of the upper splint 6 and the lower splint 5 away from the connecting rod 13 both rotate the transmission rod 14, and the transmission rod 14 is fixedly connected to the threaded rod 11; the ends of the transmission rod 14 away from the threaded rod 11 are fixedly connected to the bevel gear 15; the ends of the bevel gear 15 away from the threaded rod 11 are meshed and connected with the bevel gear 2 16; the bevel gear 2 16 located at the top is rotationally connected to the upper splint 6; the bevel gear located at the bottom is rotationally connected to the lower splint 5; the top surface of the bevel gear 2 16 located at the bottom is fixedly connected to the sliding rod 17, and the bevel gear 2 16 located at the top is slidably connected to the sliding rod 17; during operation, when the user needs to synchronously adjust the extrusion blocks 9 at the upper splint 6 and the lower splint 5, the user only needs to screw the connecting rod 13 at the end of the upper splint 6 or the lower splint 5, and When rod 13 drives threaded rod 11 to rotate, threaded rod 11 also drives transmission rod 14 to rotate, and transmission rod 14 in turn drives slide rod 17 to rotate through bevel gear 15 and bevel gear 2 16, and finally slide rod 17 transmits power to another transmission rod 14 through the cooperation of another set of bevel gear 15 and bevel gear 2 16, so that the transmission rod 14 on upper splint 6 and lower splint 5 can rotate synchronously, and transmission rod 14 is fixedly connected to threaded rod 11, so the user only needs to rotate threaded rod 11 at one of upper splint 6 or lower splint 5 to realize synchronous rotation of threaded rod 11 at both ends of upper splint 6 and lower splint 5, and then realize synchronous and equal adjustment of extrusion block 9, thereby reducing the operation difficulty of the user and improving the usability of the embodiment of the present invention.

[0025] like Figures 4 to 5As shown, the extrusion block 9 located at the upper clamping plate 6 and the extrusion block 9 located at the lower clamping plate 5 are arranged in a one-to-one correspondence; a baffle 18 is installed at the end of the extrusion block 9 away from the connecting plate; a through groove 19 is opened on the surface of the baffle 18; a baffle rod 20 is fixedly connected to the side of the upper clamping plate 6 and the lower clamping plate 5 that are close to each other; the baffle rod 20 is located on the side of the baffle 18 away from the extrusion block 9; when working, when the paired extrusion blocks 9 clamp the knot at the end of the sample, the chemical fiber rope connecting the knot and the other knots can pass through the through groove 19 on the surface of the baffle 18, and the knot itself will be blocked by the baffle 18, so as to prevent the knot at the end of the sample from coming out from between the two extrusion blocks 9 when the traction seat 3 pulls the sample again, and at the same time, the baffle rod 20 on one side of the baffle 18 can play a role in strengthening the baffle 18, so as to prevent the knot at its end from squeezing and deforming the baffle 18 when the sample is pulled.

[0026] like Figures 4 to 5 As shown, the baffle 18 is slidably connected to the extrusion block 9; the surfaces of the upper clamping plate 6 and the lower clamping plate 5 on one side close to each other are provided with a receiving groove 21 at the corresponding position of the baffle 18; a plurality of springs 22 evenly arranged are fixedly connected between the bottom of the receiving groove 21 and the baffle 18; a plurality of the springs 22 are commonly fixedly connected to a support plate 23 at one end close to the baffle 18; when working, when clamping knots of different thicknesses, the upper clamping plate 6 first presses against the lower clamping plate 5, and during the movement of the upper clamping plate 6, the baffle 18 at the upper clamping plate 6 will also squeeze Press down the baffle 18 at the clamping plate 5. At this time, if the thickness of the knot is small, a part of the two baffles 18 will be pressed into the receiving groove 21, thereby squeezing the support plate 23 and the spring 22. When the clamped knot is thicker, the spring 22 and the support plate 23 will squeeze the baffle 18, so that the part of the baffle 18 located in the receiving groove 21 is squeezed out of the receiving groove 21. In this way, it can be ensured that when clamping knots of different thicknesses, the top and bottom baffles 18 can be buckled together, thereby preventing the knot from escaping from between the squeezing blocks 9.

[0027] like Figure 4 As shown, a pair of symmetrically arranged buckle plates 24 are fixedly connected on both sides of the extrusion block 9 located at the bottom, and the buckle plates 24 are made of elastic material; the buckle plates 24 are arranged at an angle, and the ends of the paired buckle plates 24 that are close to each other are higher than the ends that are far away from each other; during operation, when the user places the end of the sample to be clamped on the extrusion plate, the user can also insert the ropes on both sides of the knot into the gap between the two buckle plates 24, and make the ropes finally restricted by the two buckle plates 24 and the extrusion block 9, thereby playing a role in fixing the end of the sample, preventing the upper clamp 6 from driving the extrusion block 9 to press the lower clamp 5, and preventing the knot of the sample from escaping from the extrusion block 9 at the lower clamp 5, resulting in the sample not being fixed properly.

[0028] like Figures 1 to 3As shown, the driving assembly includes a connecting frame 25; the connecting frame 25 is fixedly connected to the top surface of the connecting seat 4; a lower pressing block 26 is fixedly connected to the surface of one side of the upper clamping plate 6 close to the connecting frame 25, and the cross section of the lower pressing block 26 is wedge-shaped; the end of the connecting frame 25 away from the lower pressing block 26 is fixedly connected to a mounting plate 27; a moving block 28 is provided at the bottom of the connecting frame 25; the cross section of the moving block 28 is wedge-shaped and adapted to the lower pressing block 26; the end of the moving block 28 close to the mounting plate 27 is rotatably connected to a threaded rod 29, and the threaded rod 29 is threadedly connected to the mounting plate 27; when working, when the user needs to drive the upper clamping plate 6 When pressing the lower pressure plate, the user needs to screw the threaded rod 29 at the mounting plate 27 at the end of the connecting frame 25, and the threaded rod 29 pushes the moving block 28 to squeeze the lower pressure block 26, thereby driving the upper clamping plate 6 placed on the lower clamping plate 5 to continue to press the lower clamping plate 5, so that the top and bottom squeezing blocks 9 clamp the knot, and because the moving block 28 and the lower pressure block 26 are adapted to each other, the moving block 28 can evenly squeeze the lower pressure block 26, and then the lower pressure block 26 can evenly squeeze the upper clamping plate 6, so that the pressure on the top surface of the upper clamping plate 6 can be more uniform, avoiding uneven force at both ends of the upper clamping plate 6 due to the excessive length of the upper clamping plate 6.

[0029] like Figures 2 to 3 As shown, a plurality of evenly arranged limit grooves 30 are provided on the top surface of the moving block 28; limit rods 31 are slidably connected in the limit grooves 30; the limit rods 31 are fixedly connected to the connecting frame 25; during operation, when the moving block 28 moves, the limit grooves 30 on the top of the moving block 28 will cooperate with the limit rods 31 to prevent the moving block 28 from tilting when moving, thereby causing the force on the pressing block 26 to be no longer uniform.

[0030] like Figure 1 , Figure 7 and Figure 8 As shown, a strip groove 32 is provided on the top surface of the base 1; a movable seat 33 is slidably connected in the strip groove 32; a hydraulic rod 34 is fixedly connected to the top surface of the movable seat 33 and the side of the strip groove 32 close to the fixed seat 2; a receiving plate 35 is slidably connected to the telescopic end of the hydraulic rod 34; during operation, when the user needs to clamp the sample between the upper clamping plate 6 and the lower clamping plate 5, the user can first slide the movable seat 33, thereby driving the hydraulic rod 34 and the receiving plate 35 to move, so that the two receiving plates 35 can support the sample, and then the hydraulic rod 34 is started to lift the sample, thereby facilitating the user to fix the knot of the sample on the extrusion block 9.

[0031] like Figures 7 and 8As shown, a fixed column 36 is fixedly connected to one end of the receiving plate 35 close to the connecting rod 13; a sliding groove 37 is provided on the top surface of the receiving plate 35 away from the fixed column 36; a movable column 38 is arranged in the sliding groove 37; a magnet block 39 is fixedly connected to the bottom surface of the movable column 38; a metal plate 40 is fixedly connected to the bottom surface of the sliding groove 37, and the metal plate 40 is made of magnetizable metal; during operation, when the user places the sample on the receiving plate 35, the user can insert the fixed column 36 and the movable column 38 into the mesh holes on both sides of the sample, and then move the movable column 38, and then fix the position of the movable column 38 through the attraction of the magnet block 39 at the bottom of the movable column 38 and the metal plate 40, so that the movable column 38 cooperates with the fixed column 36 to support the sample, so as to avoid the middle part of the sample being too heavy, causing the sample on the receiving plate 35 to slide between the two receiving plates 35, thereby causing the sample to slide off the receiving plate 35.

[0032] During operation, in order to ensure that the tested sample can better reflect the tensile properties of the entire chemical fiber rope net, the embodiment of the present invention can be used. First, the user needs to cut off a part of the chemical fiber rope net with a complete woven structure and use it as a sample. Then the user moves the upper clamping plate 6 to move it away from the lower clamping plate 5. Then the user pulls the scissor-type telescopic frame 8 in the installation groove 7, so that it drives the extrusion blocks 9 on its surface to move synchronously and keeps the spacing between each extrusion block 9 equal, thereby adapting to the knot spacing of different sample chemical fiber rope nets. After that, the user can place the knot of the chemical fiber rope net on the extrusion block 9 at the lower clamping plate 5. Then the user drives the driving component at the connecting seat 4, and presses the upper clamping plate 6 toward the lower clamping plate 5 through the driving component, so that the extrusion blocks 9 at the upper clamping plate 6 and the lower clamping plate 5 clamp the knot of the sample. When the knots at both ends of the sample are clamped by the upper clamping plate 6 and the lower clamping plate 5 at the fixed seat 2 and the traction seat 3 respectively, the user starts the hydraulic system to drive the traction seat 3 away from the fixed seat 2, thereby stretching the sample, and obtains specific data through the tension sensor at the traction seat 3, and then obtains the tensile properties of the sample. Since the sample has the same weaving structure as the complete chemical fiber rope net, it can better reflect the tensile properties of the entire chemical fiber rope net.

[0033] When the user needs to adjust the scissors-type telescopic frame 8, the user can screw the connecting rod 13, and the connecting rod 13 drives the threaded rod 11 to rotate, and the rotating threaded rod 11 will drive the slider 12 thereon to slide, and the slider 12 is fixed to the end of the scissors-type telescopic frame 8 that is not fixed to the mounting groove 7, so the slider 12 can pull the scissors-type telescopic frame 8 to extend and contract, thereby realizing the adjustment of the scissors-type telescopic frame 8. At the same time, the slider 12 will only move when the threaded rod 11 rotates, so the threaded cooperation between the threaded rod 11 and the slider 12 can also play a locking role, thereby preventing the scissors-type telescopic frame 8 from extending or retracting due to shaking or accidental touch after the user has adjusted the spacing of the extrusion blocks 9 on the scissors-type telescopic frame 8.

[0034] When the user needs to synchronously adjust the extrusion blocks 9 at the upper clamping plate 6 and the lower clamping plate 5, the user only needs to screw the connecting rod 13 at the end of the upper clamping plate 6 or the lower clamping plate 5. When the connecting rod 13 drives the threaded rod 11 to rotate, the threaded rod 11 will also drive the transmission rod 14 to rotate, and the transmission rod 14 will drive the sliding rod 17 to rotate through the bevel gear 15 and the bevel gear 2 16, and finally the sliding rod 17 will transmit the power to the other transmission rod 14 through the cooperation of another set of bevel gear 15 and bevel gear 2 16, so that the transmission rod 14 on the upper clamping plate 6 and the lower clamping plate 5 can rotate synchronously, and the transmission rod 14 is fixedly connected with the threaded rod 11, so the user only needs to rotate the threaded rod 11 at one of the upper clamping plate 6 or the lower clamping plate 5, so as to realize the synchronous rotation of the threaded rod 11 at the upper clamping plate 6 and the lower clamping plate 5, and then realize the synchronous and equal adjustment of the extrusion block 9, thereby reducing the user's operating difficulty and improving the ease of use of the embodiment of the present invention.

[0035] When the paired extrusion blocks 9 clamp the knot at the end of the sample, the chemical fiber rope connecting the knot and the other knots can pass through the through groove 19 on the surface of the baffle 18, and the knot itself will be blocked by the baffle 18, so as to prevent the knot at the end of the sample from slipping out from between the two extrusion blocks 9 when the traction seat 3 pulls the sample again. At the same time, the baffle rod 20 on one side of the baffle 18 can strengthen the baffle 18, so as to prevent the knot at its end from squeezing and deforming the baffle 18 when the sample is pulled.

[0036] When clamping knots of different thicknesses, the upper clamp 6 first presses against the lower clamp 5, and during the movement of the upper clamp 6, the baffle 18 at the upper clamp 6 will also squeeze the baffle 18 at the lower clamp 5. At this time, if the thickness of the knot is small, a part of the two baffles 18 will be pressed into the receiving groove 21, thereby squeezing the support plate 23 and the spring 22. When the clamped knot is thicker, the spring 22 and the support plate 23 will squeeze the baffle 18 again, so that the part of the baffle 18 located in the receiving groove 21 is squeezed out of the receiving groove 21. This ensures that when clamping knots of different thicknesses, the top and bottom baffles 18 can be buckled together, thereby preventing the knot from falling out from between the squeezing blocks 9.

[0037] When the user places the end of the sample to be clamped on the extrusion plate, the user can also insert the ropes on both sides of the knot into the gap between the two buckle plates 24, and make the ropes finally restricted by the two buckle plates 24 and the extrusion block 9, thereby fixing the end of the sample and preventing the knot of the sample from escaping from the extrusion block 9 at the lower clamp plate 5 when the upper clamp plate 6 drives the extrusion block 9 to press against the lower clamp plate 5, thereby causing the sample to not be fixed properly.

[0038] When the user needs to drive the upper clamping plate 6 to press the lower pressure plate, the user needs to screw the threaded rod 29 at the mounting plate 27 at the end of the connecting frame 25, and the threaded rod 29 will push the moving block 28 to squeeze the lower pressure block 26, thereby driving the upper clamping plate 6 placed on the lower clamping plate 5 to continue to press the lower clamping plate 5, so that the top and bottom squeezing blocks 9 clamp the knot, and because the moving block 28 and the lower pressure block 26 are adapted to each other, the moving block 28 can evenly squeeze the lower pressure block 26, and then the lower pressure block 26 can evenly squeeze the upper clamping plate 6, so that the pressure on the top surface of the upper clamping plate 6 can be more uniform, avoiding uneven force at both ends of the upper clamping plate 6 due to the excessive length of the upper clamping plate 6.

[0039] When the moving block 28 moves, the limiting groove 30 on the top of the moving block 28 will cooperate with the limiting rod 31 to prevent the moving block 28 from tilting during movement, thereby causing the force on the pressing block 26 to be uneven.

[0040] When the user needs to clamp the sample between the upper clamping plate 6 and the lower clamping plate 5, the user can first slide the movable seat 33, thereby driving the hydraulic rod 34 and the receiving plate 35 to move, so that the two receiving plates 35 can support the sample, and then the hydraulic rod 34 is started to lift the sample, thereby making it convenient for the user to fix the knot of the sample on the extrusion block 9.

[0041] When the user places the sample on the receiving plate 35, the user can insert the fixed column 36 and the movable column 38 into the mesh holes on both sides of the sample, and then move the movable column 38, and then fix the position of the movable column 38 through the attraction of the magnet block 39 at the bottom of the movable column 38 and the metal plate 40, so that the movable column 38 cooperates with the fixed column 36 to support the sample, thereby preventing the middle part of the sample from being too heavy, causing the sample on the receiving plate 35 to slide between the two receiving plates 35, and then causing the sample to slide off the receiving plate 35.
