Abstract
The utility model discloses a device for testing the friction resistant performance of a rope, which comprises an upper clamp, a lower clamp, a bottom plate, support arms and a rotating shaft; upper clamp longitudinal guide rails are respectively arranged on opposite surfaces above the two support arms; the lower clamp is arranged in a lower clamp horizontal guide rail of the bottom plate; and the rope bypasses the rotating shaft with an abrasive layer and is fixedly arranged on the upper clamp and the lower clamp. According to the device for testing the friction resistant performance of the rope, the scope of application is wide, horizontal and longitudinal friction tests under different tensions can be realized, a whole test process is convenient and quick, the automation degree is high, and test data is accurate and intuitive.
Description
Technical field
The utility model belongs to netting detection technique field, especially relates to a kind of proving installation of rope crocking resistance.
Background technology
Find the performance test of still unmatchful rope rub resistance at present through consulting relevant patent.Only wearability test that is UIAA (international alpinist club) to the dynamic ropes of mountain-climbing usefulness; Concrete device is to lie on the climbing rope with 10 kilograms weight; Vertically friction on the husky wheel of rotation; The outer net that directly causes rope is ground away, and the time that rope is ground away has directly been reflected vertical antiwear property of rope.In actual use, rope also receives side-friction except receiving vertical friction, so this method has limitation.The testing standard of domestic rope key property also not to be set up; Do not form influential unified proving installation; And expansion along with rope functional diversities and range of application; Like application, except strength property, also should pay attention to performances such as rope friction resistant, rub resistance to the performance requirement of rope in military affairs, first aid, fire-fighting, exploration field.Therefore, the security for guaranteeing that rope is used in each field is necessary the rub resistance of rope is tested, and sets up scientific and reasonable crocking resistance characterization apparatus.At present, UIAA rub resistance usable range has limitation, and domestic relevant method of testing incompatibility is restricted, the test of carries product rub resistance.
Summary of the invention
The purpose of the utility model is: a kind of easy and simple to handle, rope crocking resistance proving installation that test data is accurate and visual is provided.
The technical scheme of the utility model: comprise clamper, lower gripper, base plate, sway brace, turning axle; Two sway braces are installed on the base plate; Last clamper is installed on the movement arm, and movement arm and turning axle are installed between two sway braces, on the top opposite face of two sway braces the clamper longitudinal rail are set respectively; The two ends of movement arm are arranged in the clamper longitudinal rail; Abrasive material is housed on the turning axle, and lower gripper is installed in the lower gripper cross slide way of base plate, and rope is walked around the turning axle that abrasive material is housed and is fixed on clamper and the lower gripper; Control knob is housed on the base plate, and control knob connects goes up clamper, lower gripper, movement arm and turning axle.
The beneficial effect of the utility model: rope to be tested is walked around the turning axle that abrasive material is housed and is fixed on the upper and lower holder, when abrasive material rotates with turning axle, begins the rope that weares and teares, and realizes vertical friction of rope.Have last clamper longitudinal rail on two sway braces, movement arm can be applied to the pre-tension on the rope with adjusting along moving up and down in the last clamper longitudinal rail certain limit.Lower gripper is positioned on the base plate, and it can move back and forth along the lower gripper cross slide way in the horizontal direction, realizes the side-friction of rope.The utility model is applied widely, can realize the horizontal and vertical friction test under the differential tension, and whole test process is easy, quick, automaticity is high.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Mark explanation among the figure: 1. control knob; 2. base plate; 3. sway brace; 4. abrasive material; 5. go up clamper; 6. force transducer; 7. movement arm; 8. go up the clamper longitudinal rail; 9. electrooptical device; 10. turning axle; 11. lower gripper; 12. lower gripper cross slide way; 13. display screen.
Embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Can find out from the structural representation of Fig. 1 the utility model; The utility model comprises clamper 5, lower gripper 11, base plate 2, sway brace 3, turning axle 10; Two sway braces 3 are installed on the base plate 2; Have display screen 13 and control knob 1 on the base plate, abrasive material 4 is installed on the turning axles 10, and rope is walked around abrasive material 4 and is clamped between last clamper 5 and the lower gripper 11.On two sway brace 3 opposite faces last clamper longitudinal rail 8 is arranged, movement arm 7 and turning axle 10 are installed between two sway braces 3, and movement arm 7 can move up and down along last clamper longitudinal rail 8, and last clamper 5 is installed on the movement arm 7 with force transducer.Lower gripper 11 is installed on the base plate 2, and it can move back and forth along lower gripper cross slide way 12 in the horizontal direction, and then realizes the side-friction of rope.Electrooptical device 9 is housed on sway brace 3; Electrooptical device 9 place horizontal lines are tangent with mill part external diameter, and it can detect the friction level on rope surface, when rope to be detected reaches preset friction level; Then can stop friction automatically, and then realize detection the rope frictional behaviour.Different according to actual operating position, abrasive material 4 can be selected normal sand paper, standard polyurethane plastics base fabric and standard gauze for use.The tension force of rope can be regulated through moving up and down of last clamper, and the size of tension force is confirmed according to rope diameter and operating position.Whole device links to each other with computing machine, can realize that through pre-set programs the robotization of whole testing process is carried out.
The concrete operations of the utility model are: according to actual operating position, select suitable abrasive material 4 to be fixed on the turning axle 10, the position of adjustment movement arm 7 in last clamper longitudinal rail makes it reach suitable rope tension.Prepare sample then, the intercepting sufficient length gets rope, and the one of which end is fixed on the clamper 5, and the other end is fixed on the lower gripper 11 after through abrasive material 4, and in this process, abrasive material 4 edges and last clamper 5 edges are on same perpendicular line.Select friction mode, radial friction or axial rub are pressed the control corresponding button.Press control knob 1, electrooptical device 9 is opened, and abrasive material 4 begins the rope that weares and teares, and when rope showed money or valuables one carries unintentionally, electrooptical device 9 was tested its surface hairiness sudden change friction and stopped automatically, writes down the friction number of times and exports the result through computer system.
