Technical Field
[0001] This invention relates to the field of rope strength testing technology, and in particular to a strength testing device for safety ropes based on a new material. Background Technology
[0002] Safety ropes made of new materials must undergo strength testing. The core purpose is to ensure that they can withstand extreme loads in actual use and prevent breakage that could lead to personal injury or property damage. However, the design concept and testing methods of traditional safety rope strength testing devices are mainly based on the mechanical properties of homogeneous materials such as early nylon and steel wire ropes. Their core function is limited to unidirectional static tensile testing under normal temperature and dry conditions. However, with the widespread application of new materials such as ultra-high molecular weight polyethylene, carbon fiber composite ropes, and aramid-resin hybrid ropes, the limitations of traditional equipment have been exposed in multiple dimensions, seriously hindering the scientific assessment of the full life-cycle strength of safety ropes. Therefore, single-type testing devices, due to deficiencies such as lack of environmental simulation, insufficient multi-factor coupling capability, and coarse testing dimensions, can no longer meet the needs of full life-cycle strength assessment for safety ropes made of new materials. Summary of the Invention

Absorbent sponges are fixedly mounted on the inner walls of the upper and lower openings of the outer half-tube. Rings are fixedly mounted on the upper and lower inner walls of the outer half-tube. An arc-shaped slider is movably mounted between the ring and the inner wall of the outer half-tube. A movable slider is movably mounted between the ring and the inner wall of the outer half-tube near the arc-shaped slider. A return spring is fixedly mounted between the arc-shaped slider and the movable slider. A corrugated spring is fixedly mounted on one side of the arc-shaped slider. Two sets of baffles are fixedly mounted between the two sets of arc-shaped sliders.
[0006] Preferably, limit plates are fixedly installed near the upper and lower sides of the outer half tube and the inner half tube, two sets of mounting rods are fixedly installed on the inner wall of the outer half tube, a heating tube frame is fixedly installed between the two sets of mounting rods, an electric wire is fixedly installed on one side of the heating tube frame, threaded sleeves are fixedly installed on the upper and lower sides of the outer half tube, bolts are threadedly connected to the inner side of the threaded sleeves, and a positioning groove is opened on one side of the arc-shaped slider.
[0007] Preferably, the outer side of the threaded rod is provided with two opposite helical lines, and the two sets of bevel gears are meshed.
[0008] Preferably, the movable rod is threadedly connected to the threaded rod and slidably connected to the slide rod.
[0009] Preferably, one of the two sets of environment switching components is set to rotate 180 degrees around the safety rope as the center. A certain gap is provided between the inner half-tube and the ring to allow the baffle to move. Several sets of atomizing nozzles are evenly arranged on the water supply frame. The water inlet pipe passes through the inside of the outer half-tube. The water inlet pipe is made of high-temperature resistant material. The arc-shaped slider and the movable slider are slidably set between the ring and the inner wall of the outer half-tube.
[0010] Preferably, a notch is provided on one side of the movable slider corresponding to the position of the return spring, the movable slider partially protrudes into the inner side of the outer half-tube, the baffle is attached to the outer wall of the inner half-tube, and the elastic force of the corrugated spring is less than the elastic force of the return spring.
[0011] Preferably, the conductive wire passes through the inside of the outer half-tube, the conductive wire is made of a high-temperature resistant material, the bolt passes through the inside of the threaded sleeve into the outer half-tube, and the lower side of the bolt is adapted to the positioning groove.
[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. The safety rope is clamped by the fixture of the tensile testing machine, which can be used to test the tensile strength of the safety rope. By turning the handwheel, the transmission rod and a set of bevel gears connected to it are rotated. The rotating bevel gears drive another set of bevel gears and threaded rods to rotate. The rotating threaded rod drives two sets of movable rods, fixed rods and environmental switching components connected by threads to move along two sets of sliding rods. They move closer to each other until the two sets of environmental switching components are closed together. After the safety rope is covered, the environmental switching components work together to perform environmental switching, which accelerates the change of the safety rope in a certain space.
[0013] 2. After the two sets of outer tubes are closed, the partially protruding movable sliders in the two sets of outer tubes are restricted by the limiting plates, pushing the movable slider and the arc-shaped slider back into the interior of the outer tubes, compressing the corrugated spring. At the same time, the two sets of baffles are driven by the arc-shaped sliders to adhere to the outer wall of the inner tube, blocking the two sets of vents and closing the gap between the outer and inner tubes. At this time, with the help of an external water pump, water is drawn into the water inlet pipe and water passage frame, and sprayed onto the safety rope by several sets of atomizing nozzles to wet the safety rope, simulating the strength test of the new material safety rope in rainy weather. The wet test accurately evaluates the strength retention rate and reliability of the safety rope after absorbing water by simulating a real humid environment. The baffles also have less impact on the heating tube frame, and the water-absorbing sponge can absorb the dripping water stains to prevent them from falling onto the clamps of the tensile testing machine.
[0014] 3. When simulating the strength test of the safety rope under high temperature environment, when the arc-shaped slider is pushed, the bolt connected to the threaded sleeve is tightened. The lower part of the bolt moves into the outer half tube and inserts into the positioning groove. After positioning and controlling the positioning groove and the two sets of baffles, the two sets of outer half tubes will only push the movable slider to squeeze the return spring after each closure. The movable slider retracts, and the two sets of vents are always in the open state. With the help of the power cord and the heating tube rack, the internal environment is kept at a high temperature. The strength test of the safety rope is then carried out. By reproducing the real high temperature environment, the thermal stability and high temperature strength retention rate of the safety rope can be accurately evaluated. Attached Figure Description

[0019] Please see Figures 1-6An embodiment of the present invention provides a strength testing device for a safety rope based on a new material, comprising a tensile testing machine 1, a safety rope 2 disposed in the middle of the tensile testing machine 1, a control component 3 disposed between the two side columns of the tensile testing machine 1, and two sets of environment switching components 4 disposed between the control components 3. The control component 3 includes two sets of U-shaped frames 31 fixedly installed between the two side columns of the tensile testing machine 1. A transmission rod 32 is rotatably disposed on the inner side of each of the two sets of U-shaped frames 31. A handwheel 33 is fixedly disposed on the front side of the transmission rod 32. A threaded rod 34 is rotatably disposed between the two sets of U-shaped frames 31 near the rear side. A bevel gear 35 is fixedly disposed on one end of the threaded rod 34 near the inner side of one set of U-shaped frames 31 and on the outer side of one set of transmission rods 32. A sliding rod 36 is fixedly disposed on the opposite side of each of the two sets of U-shaped frames 31 near the front side. Two sets of movable rods 37 are sleeved on the outer side of the threaded rod 34 and the two sets of sliding rods 36. A fixed rod 38 is fixedly disposed on the opposite side of each of the two sets of movable rods 37.
[0020] The outer side of the threaded rod 34 is provided with two opposite spiral patterns, the two sets of bevel gears 35 are meshed, and the movable rod 37 is threadedly connected to the threaded rod 34 and slidably connected to the slide rod 36.
[0021] After connecting the water inlet pipe 46 and the power supply wire 417 to the pump and power supply respectively, the safety rope 2 is clamped by the clamp of the tensile testing machine 1 to perform a tensile strength test on the safety rope 2. By rotating the handwheel 33, the transmission rod 32 and a set of bevel gears 35 connected to it are rotated. The rotating bevel gears 35 drive another set of bevel gears 35 and threaded rods 34 to rotate. The rotating threaded rods 34 drive the two sets of movable rods 37, fixed rods 38 and environmental switching components 4 connected by threads to move along the two sets of sliding rods 36 and move closer to each other until the two sets of environmental switching components 4 are closed together. After covering the safety rope 2, the environmental switching components 4 are used to perform environmental switching, which accelerates the change of the safety rope 2 in a certain space.
[0022] The environment switching component 4 includes two sets of outer half-tubes 41 fixedly mounted at one end of two sets of fixed rods 38. An inner half-tube 42 is fixedly mounted inside the outer half-tube 41. Two sets of air vents 43 are opened on the inner side of the inner half-tube 42. A water-passing frame 44 is fixedly installed on the inner half-tube 42 near the rear. Several sets of atomizing nozzles 45 are fixedly mounted at one end of the water-passing frame 44. A water inlet pipe 46 is fixedly mounted at the other end of the water-passing frame 44. Water-absorbing sponges 4 are fixedly mounted on the inner walls of the upper and lower openings of the outer half-tube 41. 7. A ring 48 is fixedly installed on the inner wall of both the upper and lower sides of the outer half tube 41. An arc-shaped slider 49 is movably installed between the ring 48 and the inner wall of the outer half tube 41. A movable slider 410 is movably installed between the ring 48 and the inner wall of the outer half tube 41 near the arc-shaped slider 49. A return spring 411 is fixedly installed between the arc-shaped slider 49 and the movable slider 410. A corrugated spring sheet 412 is fixedly installed on one side of the arc-shaped slider 49. Two sets of baffles 413 are fixedly installed between the two sets of arc-shaped sliders 49.
[0023] One of the two sets of environment switching components 4 is set to rotate 180 degrees around the safety rope 2. A certain gap is provided between the inner half-tube 42 and the ring 48 to allow the baffle 413 to move. Several sets of atomizing nozzles 45 are evenly arranged on the water supply frame 44. The water inlet pipe 46 passes through the inside of the outer half-tube 41. The water inlet pipe 46 is made of high-temperature resistant material. The arc-shaped slider 49 and the movable slider 410 are slidably set between the ring 48 and the inner wall of the outer half-tube 41. A notch is opened on one side of the movable slider 410 corresponding to the position of the return spring 411. The movable slider 410 protrudes partially from the inner side of the outer half-tube 41. The baffle 413 is attached to the outer wall of the inner half-tube 42. The elastic force of the corrugated spring 412 is less than the elastic force of the return spring 411.
[0024] After the two sets of outer half-tubes 41 are closed, the partially protruding movable sliders 410 in the two sets of outer half-tubes 41 are restricted by the limiting piece 414, pushing the movable sliders 410 and the arc-shaped sliders 49 back into the interior of the outer half-tubes 41, compressing the corrugated spring pieces 412. At the same time, the two sets of baffles 413 are driven by the arc-shaped sliders 49 to adhere to the outer wall of the inner half-tube 42, blocking the two sets of vents 43, thus closing the gap between the outer half-tubes 41 and the inner half-tubes 42. At this time, in conjunction with an external water pump, the pump can be used to draw water. Water enters the inlet pipe 46 and the water flow rack 44, and is sprayed onto the safety rope 2 by several sets of atomizing nozzles 45, wetting the safety rope 2. This simulates the strength test of the new material safety rope 2 in rainy weather. The wet test accurately evaluates the strength retention rate and reliability of the safety rope after absorbing water by simulating a real humid environment. The baffle 413 also minimizes the impact on the heating tube rack 416. At the same time, the water-absorbing sponge 47 can absorb the dripping water stains and prevent them from falling onto the clamps of the tensile testing machine 1.
[0025] Limiting plates 414 are fixedly installed near the upper and lower sides of the outer half tube 41 and the inner half tube 42. Two sets of mounting rods 415 are fixedly installed on the inner wall of the outer half tube 41. A heating tube bracket 416 is fixedly installed between the two sets of mounting rods 415. A power wire 417 is fixedly installed on one side of the heating tube bracket 416. Threaded sleeves 418 are fixedly installed on the upper and lower sides of the outer half tube 41. Bolts 419 are threadedly connected to the inner side of the threaded sleeves 418. A positioning groove 420 is opened on one side of the arc-shaped slider 49.
[0026] The power cable 417 passes through the inside of the outer half-tube 41. The power cable 417 is made of high-temperature resistant material. The bolt 419 passes through the inside of the threaded sleeve 418 into the outer half-tube 41. The lower side of the bolt 419 is matched with the positioning groove 420.
[0027] When the strength test of the safety rope 2 needs to be simulated under high temperature environment, when the arc-shaped slider 49 is pushed, the bolt 419 connected to the threaded sleeve 418 is screwed. The lower part of the bolt 419 moves into the outer half tube 41 and inserts into the positioning groove 420. After positioning and controlling the positioning groove 420 and the two sets of baffles 413, the two sets of outer half tubes 41 will only push the movable slider 410 to squeeze the reset spring 411 after each closure. The movable slider 410 retracts, and the two sets of vents 43 are always in the open state. With the help of the power cord 417 and the heating tube frame 416, the internal environment is heated to a high temperature state, so that the strength test of the safety rope 2 can be carried out. By reproducing the real high temperature environment, the thermal stability and high temperature strength retention rate of the safety rope can be accurately evaluated.
[0028] Working principle: First, connect the inlet pipe 46 and the power cord 417 to the pump and power supply respectively. During use, the safety rope 2 is clamped by the clamps of the tensile testing machine 1 to perform a tensile strength test on the safety rope 2. By rotating the handwheel 33, the transmission rod 32 and a set of bevel gears 35 connected to it rotate. The rotating bevel gears 35 drive another set of bevel gears 35 and the threaded rod 34 to rotate. The rotating threaded rod 34 drives the two sets of movable rods 37, fixed rods 38, and environmental switching components 4 connected by threads to move along the two sets of sliding rods 36, and move closer to each other until the two sets of environmental switching components 4 are closed. Together, after the safety rope 2 is covered, the environment switching component 4 is used to switch the environment, accelerating the change of the safety rope 2 within a certain space. Additionally, after the two sets of outer half-tubes 41 are closed, the partially protruding movable sliders 410 in the two sets of outer half-tubes 41 are restricted by the limiting plate 414, pushing the movable sliders 410 and the arc-shaped slider 49 back into the interior of the outer half-tubes 41, compressing the corrugated spring 412. Simultaneously, the two sets of baffles 413 are driven by the arc-shaped slider 49 to adhere to the outer wall of the inner half-tube 42, blocking the two sets of vents 43, thus closing the gap between the outer half-tube 41 and the inner half-tube 42. At this time, an external water pump is used. Water is pumped into the inlet pipe 46 and the water frame 44, and sprayed onto the safety rope 2 by several sets of atomizing nozzles 45, wetting the safety rope 2. This simulates the strength test of the new material safety rope 2 in rainy weather. The wet test accurately evaluates the strength retention rate and reliability of the safety rope after water absorption by simulating a real humid environment. The baffle 413 also minimizes the impact on the heating tube frame 416. At the same time, the water-absorbing sponge 47 can absorb the dripping water stains and prevent them from falling onto the clamps of the tensile testing machine 1. Secondly, when it is necessary to simulate the strength test of the safety rope 2 under high temperature environment, when the arc-shaped slider 49 is pushed, the threaded connection on the threaded sleeve 418 is turned. Bolt 419 moves its lower side into the outer half-tube 41 and inserts into the positioning groove 420. After positioning and controlling the positioning groove 420 and the two sets of baffles 413, the two sets of outer half-tubes 41 will only push the movable slider 410 to squeeze the reset spring 411 after each closure. The movable slider 410 retracts, keeping the two sets of vents 43 in the open state. With the help of the power cord 417 and the heating tube frame 416, the internal environment is heated to a high temperature, so that the strength test of the safety rope 2 can be carried out. By reproducing the real high temperature environment, the thermal stability and high temperature strength retention rate of the safety rope can be accurately evaluated.
[0029] The tensile testing machine 1, safety rope 2, atomizing nozzle 45, heating tube frame 416, and power cord 417 electrical components in this invention are existing structures in the field, and their usage and connection methods are common knowledge in the field. Their working principles are already known technologies, and the appropriate model is selected according to actual use, so they will not be explained in detail.
