Abstract
The utility model discloses a rope bending fatigue tester comprising a testing bracket (1) as well as a motor B (3), an upper drive screw (6), an upper testing pulley (4), a motor A (2), a lower testing pulley (5), a testing chuck (7) and a counter (9) which are arranged on the testing bracket (1). The tester is simple in structure, a rope sample is driven to bend forward and backward by mainly utilizing the rotation of the testing pulleys, the counter is used for counting the cycle index, the breaking strength reduction rate is used as an evaluation value of the rope bending fatigue, the operation is convenient, the sample test for two rope samples can be preformed once, the testing efficiency is improved, the cost is low and the testing effect is accurate.
Description
Technical field
The utility model relates to rope performance testing device, specifically a kind of rope bending fatigue tester.
Background technology
At present, for rope series products people, be more to pay close attention to its brute force, breaking elongation, impact property etc., and the fatigue property of rope product is paid attention to not.But bending is in use occurring rope almost everywhere, and this just relates to the bending fatigue of rope, but evaluating apparatus and the method for unified rope bending fatigue are not also set up and formed to the testing standard of domestic rope key property.Along with the variation of rope kind and function and the expansion of range of application, as the application in fields such as fire-fighting, first aid, military affairs, explorations, the complicacy of applied environment, the requirement of rope is not only confined to powerful grade for basic index again, therefore, to the fatigue property of rope, test significant.But, current domestic method of testing and the device that is not directed to rope bending performance, the relevant method of testing in other field is also not suitable with the test of rope product bending property.
Summary of the invention
For solving the technical matters of above-mentioned existence, the utility model provides a kind of rope bending fatigue tester, and simple in structure, testing efficiency is high, easy to use, and cost is low.
For achieving the above object, the technical scheme that the utility model adopts is:
A kind of rope bending fatigue tester, comprise test bracket and be arranged at the motor B on test bracket, upper drive screw, test top sheave, motor A, test lower sheave, test cartridge sum counter, described motor B is arranged at test bracket top and is connected with upper drive screw, described test top sheave is fixed on the bottom of drive screw, described motor A is arranged at the bottom of test bracket and is connected with test lower sheave, described test lower sheave be arranged at test top sheave under, described counter is fixedly installed on a side of test bracket, during test, rope sample is through test top sheave, test lower sheave is also fixed by test cartridge.
On described test bracket, be provided with guide rail pole, connecting test chuck on described guide rail pole, described test cartridge can slide up and down along guide rail pole.
Described test cartridge is set to two of left and right, and described guide rail pole is set to be fixed on the both sides of test bracket.
The utility model is simple in structure, mainly utilize the rope sample that rotarily drives of test sheave to do cyclic bending motion, utilize counter computation cycles number of times, evaluation of estimate by disrumpent feelings powerful reduced rate as rope bending fatigue degree, easy to operate, can once carry out two sections of rope sample tests, improved testing efficiency, cost is low, and test effect is accurate.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is transmission schematic diagram of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail:
As Fig. 1, shown in 2, this rope bending fatigue tester, comprise test bracket 1 and be arranged at the motor B3 on test bracket 1, upper drive screw 6, test top sheave 4, motor A2, test lower sheave 5, test cartridge 7 sum counters 9, described motor B3 is arranged at test bracket 1 top and is connected with upper drive screw 6, described test top sheave 4 is fixed on the bottom of drive screw 6, described motor A2 is arranged at the bottom of test bracket 1 and is connected with test lower sheave 5, described test lower sheave 5 be arranged at test top sheave 4 under, described counter 9 is fixedly installed on a side of test bracket 1, during test, rope sample is through test top sheave 4, test lower sheave 5 is also fixing by test cartridge 7.
Preferably, on described test bracket 1, be provided with guide rail pole 8, connecting test chuck 7 on described guide rail pole 8, described test cartridge 7 can slide up and down along guide rail pole 8, the movement locus of steady testing rope sample.
Preferably, described test cartridge 7 is set to two of left and right, and described guide rail pole 8 is set to be fixed on the both sides of test bracket 1, can to two sections of rope sample, carry out bending fatigue test simultaneously, improves testing efficiency.
As shown in Figure 2, the utility model is when work, first start motor B3, in driving, drive screw 6 and then drive test top sheave 4 decline, get two sections of test rope sample, they are added respectively and be held in two test cartridge 7 also through in test top sheave 4 and test lower sheave 5, and then start drive screw 6 drive test lower sheaves 5 in motor B3, driving and rise, make rope sample tensioning.
Start motor A2 and drive test lower sheave 4 to rotate, and then drive specimen motion, after specimen enters pulley, enter case of bending.Guide rail pole 8 is used for the movement locus of steady testing rope sample, and counter 9 records bend cycles number of times, and after the reversed bending of certain number of times, the disrumpent feelings brute force of test rope sample, is used disrumpent feelings powerful reduced rate as the evaluation of estimate of rope bending fatigue.
Certainly; above-mentioned explanation is not to restriction of the present utility model; the utility model is also not limited in above-mentioned giving an example, and the variation that those skilled in the art make in essential scope of the present utility model, remodeling, interpolation or replacement, also should belong to protection domain of the present utility model.
