[0002] Safety rope nets have a wide range of applications in many fields such as construction, mining, power, and fire protection. In construction, they are used to prevent people and objects from falling; in mining operations, they ensure the safety of miners working at heights; in power maintenance, they provide safety protection for workers; and in fire rescue, they can serve as a rescue channel or buffer device.

[0003] Patent CN219842266U discloses a device for testing the tensile strength of braided yarn. The device includes a base plate, a positioning plate fixedly connected to the left side of the top of the base plate, a tension sensor disposed on the right side of the positioning plate, a vertical plate fixedly connected to the right side of the top of the base plate, a threaded rod threadedly connected to the right side of the vertical plate, a connecting plate rotatably connected to the left side of the threaded rod via a bearing, and a concave frame fixedly connected to the left side of the connecting plate. A through hole is formed at the top of the concave frame. The device comprises a tension sensor, a vertical plate, a threaded rod, a connecting plate, a concave frame, a through hole, a pin, and a pin hole. When used in conjunction with other devices, the tensile strength of braided ropes can be tested. By setting up a protective cover, the outer perimeter of the braided rope can be protected to prevent accidental injury to workers in the event of a breakage. With the above structure, it has the advantage of protecting the braided rope and preventing accidental injury to workers in the event of a breakage. However, during the testing process, the safety rope net needs to be manually fixed before testing can be carried out, which leads to a long preparation time and affects the testing efficiency. Therefore, a safety rope net braiding tensile strength testing device with intelligent sensors is proposed to solve the above-mentioned problems. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a safety rope net weaving tensile strength testing device with intelligent sensor, which addresses the shortcomings of the prior art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a safety rope net weaving tensile strength testing device with intelligent sensors, comprising: a support platform fixedly connected to the top of the workbench; a dual-axis motor fixedly connected to the inner wall of the workbench; a threaded rod fixedly connected to the output end of the dual-axis motor; a movable plate threadedly connected to the circumferential surface of the threaded rod; a hollow plate fixedly connected to the left side of the support platform; a guide rail fixedly connected to the inner wall of the workbench; and a pull plate fixedly connected to the inner wall of the movable plate. When testing is required, the dual-axis motor drives the pull plate to move, thereby gradually increasing the tension on the safety rope net until the rope net breaks or exhibits a specified damage phenomenon, enabling accurate measurement of its tensile strength to ensure the rope net can protect personnel safety in the event of danger. A straight rod is fixedly connected to the inner wall of the pull plate by a spring. The top of the support platform is equipped with a protective mechanism for personnel during testing. The inner wall of the workbench is equipped with an auxiliary mechanism to improve the fixing effect. A pressure plate is slidably connected to the circumferential surface of the straight rod, and a pulley block is fixedly connected to the top of the pressure plate. During testing, the pull plate drives the pulley block to move downward, thereby automatically fixing the safety rope, saving the tedious steps of manual fixing, and improving the testing efficiency of safety ropes in batch testing. The circumferential surface of the threaded rod is rotatably connected to the inner wall of the workbench. The bottom of the pull plate is slidably connected to the inner wall of the guide rail, and the guide rail is used to limit the pull plate to ensure that the pull plate can operate normally. A sensor is installed on the inner wall of the pull plate to detect the firmness of the safety rope. The bottom of the perforated plate is in contact with the circumferential surface of the pulley block, and the pulley block is subjected to the squeezing force from the perforated plate during operation.

[0006] Preferably, the protective mechanism includes a chamfered block fixedly connected to the top of the support platform. An L-shaped plate is fixedly connected to the left side of the pull plate, and a half-screw is movably connected to the inner wall of the L-shaped plate. A rotating plate is fixedly connected to the circumferential surface of the half-screw, and a protective plate is fixedly connected to the rear of the rotating plate. A collection groove is fixedly connected to the inner wall of the workbench. During testing, the pull plate drives the protective plate to rotate, thus protecting the testing personnel after placement. This prevents the safety rope net from breaking under high tension, prevents fragments from flying, and avoids injury to the testing personnel. A shaking plate is rotatably connected to the inner wall of the workbench via a torsion spring, and the top of the shaking plate is fixedly connected to... A fixed connection with a protrusion is provided. A pulley plate is fixedly connected to the left side of the pull plate. During the testing process, the movement of the pull plate causes the shaking plate to swing at a high frequency, thereby shaking off the broken safety rope nets that fall onto the workbench surface into the collection trough, preventing them from accumulating on the workbench, affecting the normal operation of the testing device and the operator's line of sight, and ensuring that each test is not interfered with by previous debris, thus guaranteeing the accuracy of the test results. The circumferential surface of the half-screw is rotatably connected to the inner wall of the chamfer block. The bottom of the protective plate is in contact with the top of the support platform, and the support platform is used to support the protective plate. The top of the shaking plate is in contact with the bottom of the pulley plate, and the pulley plate will contact the protrusion and apply pressure to the protrusion during operation.

[0007] Preferably, the auxiliary mechanism includes a U-shaped plate one, which is fixedly connected to the top of the shaking plate. A connecting plate is rotatably connected to the inner wall of the U-shaped plate one, and a second U-shaped plate is rotatably connected to the inner wall of the connecting plate. During the collection process, the shaking plate pulls the push plate to move, thereby pushing the piled-up rope netting at the edge of the workbench into the shaking area. This further improves the rope netting collection effect and reduces residue, improving the overall cleaning effect of the equipment and saving maintenance time and costs. A push plate is fixedly connected to the front of the second U-shaped plate, a self-locking block is fixedly connected to the left side of the pressure plate, and an L-shaped plate is fixedly connected to the left side of the pull plate. The inner wall of the second part is slidably connected to a sliding rod via a spring. A ramp is fixedly connected to the right side of the sliding rod. During the fixing process, the ramp is locked in the inner wall of the self-locking block, thereby strengthening the fixation of the rope net and ensuring that the rope net will not fall off during the testing process. This improves the safety of the equipment during use, further enhances the stability of the equipment during testing, extends the service life of the equipment parts, and makes the testing safer for the staff. The top of the workbench is slidably connected to the bottom of the push plate, and the right side of the ramp is in contact with the left side of the pull plate. The self-locking block will contact the ramp during operation and limit the self-locking block.

[0008] The present invention, by adopting the above technical solution, can bring the following beneficial effects:

[0009] 1. This safety rope net weaving tensile strength testing device with intelligent sensors operates through the coordinated operation of a workbench, support platform, dual-axis motor, threaded rod, moving plate, perforated plate, guide rail, pull plate straight rod, pressure plate, and pulley block. When testing is required, the dual-axis motor drives the pull plate to move, gradually increasing the tension on the safety rope net until the rope net breaks or exhibits the specified damage phenomenon, accurately measuring its tensile strength to ensure the rope net can protect personnel safety in the event of danger. During testing, the pull plate drives the pulley block to move downwards, automatically fixing the safety rope, saving the tedious manual fixing steps, and thus improving the testing efficiency of safety ropes in batch testing.

[0010] 2. This safety rope net weaving tensile strength testing device with intelligent sensors works by coordinating the chamfered block, L-shaped plate, half-screw, rotating plate, protective plate, and collection trough. During testing, the pull plate drives the protective plate to rotate, thus protecting the testing personnel after placement. This prevents the safety rope net from breaking under great tension, prevents broken rope net fragments from flying, and prevents injury to the testing personnel.

[0011] 3. This safety rope netting tensile strength testing device with intelligent sensors works in coordination with a shaking plate, a protrusion, and a pulley plate. During the testing process, the moving pull plate causes the shaking plate to swing at a high frequency, which shakes the broken safety rope netting that falls onto the workbench surface into the collection trough, preventing it from accumulating on the workbench and affecting the normal operation of the testing device and the operator's line of sight. It also ensures that each test is not affected by previous debris, guaranteeing the accuracy of the test results.

[0012] 4. This safety rope net weaving tensile strength testing device with intelligent sensors works in coordination between U-shaped plate one, connecting plate and U-shaped plate two. During the collection process, the shaking plate pulls the push plate to move, thereby pushing the broken rope net accumulated on the edge of the workbench to the shaking area. This can further improve the collection effect of the rope net and reduce residue, improve the overall cleaning effect of the equipment, and save maintenance time and costs.

[0013] 5. This safety rope net weaving tensile strength testing device with intelligent sensors works in conjunction with a push plate, self-locking block, L-shaped plate, sliding rod, and inclined plate. During the fixing process, the inclined plate is locked in the inner wall of the self-locking block, which strengthens the fixation of the rope net and ensures that the rope net will not fall off during the testing process. This improves the safety of the equipment during use, further enhances the stability of the equipment during testing, extends the service life of the equipment parts, and makes the testing safer for the staff.

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Please see Figures 1-9 One embodiment of the present invention is: a safety rope net weaving tensile strength testing device with intelligent sensor, comprising: a support platform 2 fixedly connected to the top of the workbench 1; a dual-axis motor 3 fixedly connected to the inner wall of the workbench 1; a threaded rod 4 fixedly connected to the output end of the dual-axis motor 3; a movable plate 5 threadedly connected to the circumferential surface of the threaded rod 4; a hollow plate 6 fixedly connected to the left side of the support platform 2; a guide rail 7 fixedly connected to the inner wall of the workbench 1; a pull plate 8 fixedly connected to the inner wall of the movable plate 5; a straight rod 9 fixedly connected to the inner wall of the pull plate 8 by a spring; a protective mechanism 12 for protecting personnel during testing provided at the top of the support platform 2; an auxiliary mechanism 13 for improving the fixing effect provided on the inner wall of the workbench 1; a pressure plate 10 slidably connected to the circumferential surface of the straight rod 9; and a pulley block 11 fixedly connected to the top of the pressure plate 10.

[0026] When testing is required, the safety rope net is placed on the inner wall of the pull plate 8. At this time, the dual-axis motor 3 starts and drives the threaded rod 4 to rotate. The rotation of the threaded rod 4 drives the moving plate 5 to move through the threads on its surface. The movement of the moving plate 5 drives the pull plate 8 to move, thereby gradually increasing the tension on the safety rope net until the rope net breaks or exhibits the specified damage phenomenon. Only by accurately measuring its tensile strength can we ensure that the rope net can protect personnel safety in the event of danger.

[0027] The circumferential surface of the threaded rod 4 is rotatably connected to the inner wall of the workbench 1, the bottom of the pull plate 8 is slidably connected to the inner wall of the guide rail 7, and the guide rail 7 is used to limit the pull plate 8 to ensure that the pull plate 8 can operate normally. The inner wall of the pull plate 8 is equipped with a sensor to detect the firmness of the safety rope. The bottom of the hollow plate 6 is in contact with the circumferential surface of the pulley block 11, and the pulley block 11 will be subjected to the squeezing force from the hollow plate 6 during operation.

[0028] During the stretching process, the pull plate 8 moves to the right, causing the straight rod 9 to move. The straight rod 9 moves, causing the pressure plate 10 to move. The pressure plate 10 moves to the right, causing the pulley block 11 to move. During the movement, the pulley block 11 contacts the bottom of the hollow plate 6. During the movement, the pulley block 11 is squeezed by the inclined surface of the hollow plate 6, causing the pulley block 11 to move downward, thereby automatically fixing the safety rope. This saves the tedious steps of manual fixing and improves the testing efficiency of safety ropes in batch testing. After the safety rope is fixed, the pull plate 8 continues to move. At this time, the pulley block 11 will move to the horizontal position of the hollow plate 6, so as not to affect the stretching of the pull plate 8.

[0029] Overall working principle: When testing is required, the dual-axis motor 3 drives the pull plate 8 to move, thereby gradually increasing the tension on the safety rope net until the rope net breaks or exhibits the specified damage phenomenon, which can accurately measure its tensile strength; during testing, the pull plate 8 drives the pulley block 11 to move downward, thereby automatically fixing the safety rope, saving the tedious steps of manual fixing, and thus improving the testing efficiency of safety ropes in batch testing.

[0030] The protective mechanism 12 includes a chamfered block 121, which is fixedly connected to the top of the support platform 2. An L-shaped plate 122 is fixedly connected to the left side of the pull plate 8. A half-screw 123 is movably connected to the inner wall of the L-shaped plate 122. A rotating plate 124 is fixedly connected to the circumferential surface of the half-screw 123. A protective plate 125 is fixedly connected to the rear of the rotating plate 124. A collection trough 126 is fixedly connected to the inner wall of the workbench 1.

[0031] During testing, the pull plate 8 moves to the left, causing the L-shaped plate 122 to move to the left as well. During this movement, the L-shaped plate 122 contacts the groove on the inner wall of the half-lead screw 123, which in turn causes the half-lead screw 123 to rotate. The rotation of the half-lead screw 123 causes the rotating plate 124 to rotate, which in turn causes the protective plate 125 to rotate. This provides protection for the testing personnel after they are placed, preventing the safety rope net from breaking under great tension. It also prevents fragments of the broken rope net from flying and causing injury to the testing personnel.

[0032] The inner wall of the workbench 1 is rotatably connected to a vibrating plate 127 via a torsion spring. A protrusion 128 is fixedly connected to the top of the vibrating plate 127. A pulley plate 129 is fixedly connected to the left side of the pull plate 8. The circumferential surface of the half-lead screw 123 is rotatably connected to the inner wall of the chamfer block 121. The bottom of the protective plate 125 is in contact with the top of the support platform 2, and the support platform 2 is used to support the protective plate 125. The top of the vibrating plate 127 is in contact with the bottom of the pulley plate 129, and the pulley plate 129 will contact the protrusion 128 and apply a squeezing force to the protrusion 128 during operation.

[0033] During the testing process, the pull plate 8 moves, causing the pulley plate 129 to rotate. As the pulley plate 129 moves, it comes into contact with the protrusion 128 and exerts a downward squeezing force on the protrusion 128, forcing the protrusion 128 to move downward. The downward movement of the protrusion 128 causes the shaking plate 127 to rotate downward. At the same time, the pulleys on the inner wall of the pulley plate 129 reduce the friction between the pulley plate 129 and the shaking plate 127. After the pulley plate 129 passes the protrusion 128, it no longer exerts a squeezing force on the protrusion 128. At this time, the shaking plate 127 is reset and rotated by the torsion spring. Through the arrangement of multiple protrusions 128, the shaking plate 127 can swing at a high frequency, thereby shaking the broken safety rope net that has fallen on the surface of the workbench 1 into the collection tank 126, preventing it from accumulating on the workbench 1, affecting the normal operation of the testing device and the operator's working line of sight, and ensuring that each test is not affected by previous debris, thus ensuring the accuracy of the test results.

[0034] Overall working principle: During testing, the pull plate 8 drives the protective plate 125 to rotate, thereby protecting the testing personnel after they are placed in the equipment. This prevents the safety rope net from breaking under great tension and avoids injury to the testing personnel. During the testing process, the movement of the pull plate 8 causes the shaking plate 127 to swing at a high frequency, which shakes the broken safety rope net that falls on the surface of the workbench 1 into the collection tank 126, preventing it from accumulating on the workbench 1 and ensuring the accuracy of the test results.

[0035] Please see Figures 1-9 Based on the above embodiments, in another embodiment of the present invention, the auxiliary mechanism 13 includes a U-shaped plate 131, which is fixedly connected to the top of the shaking plate 127. A connecting plate 132 is rotatably connected to the inner wall of the U-shaped plate 131, and a U-shaped plate 133 is rotatably connected to the inner wall of the connecting plate 132.

[0036] During the collection process, the shaking plate 127 rotates, causing the U-shaped plate 131 to rotate. The rotation of the U-shaped plate 131 causes the connecting plate 132 to move. The movement of the connecting plate 132 pulls the U-shaped plate 133 to move, and the movement of the U-shaped plate 133 pulls the push plate 134 to move. This pushes the shredded rope net accumulated on the edge of the workbench 1 to the shaking area, which can further improve the collection effect of the rope net and reduce residue, improve the overall cleaning effect of the equipment, and save maintenance time and costs.

[0037] A push plate 134 is fixedly connected to the front of the U-shaped plate 133. A self-locking block 135 is fixedly connected to the left side of the pressure plate 10. An L-shaped plate 136 is fixedly connected to the left side of the pull plate 8. A sliding rod 137 is slidably connected to the inner wall of the L-shaped plate 136 via a spring. An inclined plate 138 is fixedly connected to the right side of the sliding rod 137. The top of the worktable 1 is slidably connected to the bottom of the push plate 134. The right side of the inclined plate 138 is in contact with the left side of the pull plate 8. The self-locking block 135 will contact the inclined plate 138 during operation and limit the self-locking block 135.

[0038] During the fixing process, the pressure plate 10 moves downward, causing the self-locking block 135 to move downward as well. As the self-locking block 135 moves downward, it comes into contact with the inclined plate 138 and applies a force to the left, causing the inclined plate 138 to move to the left. This movement of the inclined plate 138 causes the sliding rod 137 to move. As the sliding rod continues to move, once the hole in the self-locking block 135 coincides with the inclined plate 138, the sliding rod 137 is reset by a torsion spring. This causes the inclined plate 138 to lock into the inner wall of the self-locking block 135, thus strengthening the fixation of the rope net and ensuring that the rope net will not fall off during testing. This improves the safety of the equipment during use, further enhances its stability during testing, extends the service life of equipment parts, and makes testing safer for personnel.

[0039] Overall working principle: During the collection process, the shaking plate 127 pulls the push plate 134 to move, thereby pushing the piled-up rope netting on the edge of the workbench 1 into the shaking area, which can further improve the collection effect of the rope netting and reduce residue; during the fixing process, the inclined plate 138 is locked in the inner wall of the self-locking block 135, which can strengthen the fixing of the rope netting and ensure that the rope netting will not fall off during the detection process, thereby improving the safety of the equipment during use.

[0040] This invention provides a device for detecting the tensile strength of safety rope netting weave with an intelligent sensor. Many methods and approaches exist for implementing this technical solution; the above description is merely a preferred embodiment of the invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this invention, and these improvements and modifications should also be considered within the scope of protection of this invention. All components not explicitly stated in this embodiment can be implemented using existing technologies.
