Attached drawing 2 is steel wire rope of the present invention and the ram speed graph of the repeated bend test system of trailing cable.
Specific embodiment
Attached drawing 1 is the repeated bend test system structure diagram of steel wire rope of the present invention and trailing cable, and in figure, 1 is electric
Machine, 2 be driving wheel, and 3 be driven wheel, and 4 be crank, and 5 be connecting rod, and 6 be sliding block, and 7 be line slideway, and 8 be outer fixed pulley, and 9 be interior
Fixed pulley, 10 be counterweight, and 11 be counter.The repeated bend test system of steel wire rope and trailing cable of the present invention includes system frame
Frame, transmission mechanism, slider-crank mechanism, balance weight mechanism and counter 12；The transmission mechanism include motor 1, driving wheel 2 and from
Driving wheel 3, driving wheel 2 are fixed on motor 1, and motor 1 and the interval of driven wheel 3 are fixed on the right side of system framework, driving wheel 2, from
Belt or chain are provided between driving wheel 3；The slider-crank mechanism includes crank 4, connecting rod 5, sliding block 6 and line slideway 7；Directly
Line guide rail 7 is fixed on middle part, sliding block 6 on system framework and is sleeved on line slideway 7, and one end and 3 shaft of driven wheel of crank 4 are consolidated
Fixed connection, one end of the other end and connecting rod 5 are hinged, and the other end and sliding block 6 of connecting rod 5 are hinged；It is outer fixed that the balance weight mechanism includes
Pulley 8, interior fixed pulley 9 and counterweight 10；Two outer fixed pulleys 8 are separately positioned on the system framework of 7 both sides of line slideway, two
Interior fixed pulley 9 is separately positioned on the system framework of two outer 8 insides of fixed pulley, and counterweight 10 is placed on the lower section of interior fixed pulley 9；
The counter 11 is arranged on the upper left side of line slideway 7.
During experiment, the steel wire rope or cable to be detected of appropriate length are first sheared, by one of steel wire rope to be detected or cable
End is connected in the counterweight of left side, another end of steel wire rope to be detected or cable is passed through left inside fixed pulley from inside, around
It is wound on after left fixed pulley half-turn from outside on left outside fixed pulley, continuation pulls to the right steel wire rope or cable to be detected until fixed outside the right side
Pulley top installs around steel wire rope or cable to be detected by the way of identical with left side balance weight mechanism, finally, right side is matched somebody with somebody reconnection
It is connected on another end of steel wire rope or cable to be detected, also, left and right side counterweight is made to have the height of setting from the ground.
Steel wire rope or cable to be detected directly over sliding block with sliding block is linked together, opens motor, driving wheel is in the drive of motor
Lower rotation, driven wheel rotates under the drive of driving wheel, and so as to which crank be driven to rotate, one end of crank handle turns connecting rod turns with crank
Dynamic, the other end of connecting rod does linear slide on slide.So as to drive steel wire rope or cable to be detected are left and right to move in parallel, together
When, the also bending motion between inside and outside fixed pulley.The upper left counter of slide is arranged on then to steel wire rope to be detected or electricity
The mobile number of cable is counted namely the number of bends of steel wire rope to be detected or cable is counted.
In order to preferably achieve the purpose that deceleration, the master of the repeated bend test system of steel wire rope and trailing cable of the present invention
The diameter of driving wheel is less than the diameter of driven wheel.
Attached drawing 2 is the ram speed graph of the repeated bend test system of steel wire rope of the present invention and trailing cable, transverse axis
For time shaft, vertical pivot is speed axis, and as seen from the figure, when the angle of crank 4 and connecting rod 5 is 0 ° or 180 °, the speed of sliding block 6 is
0；When the angle of crank 4 and connecting rod 5 is 90 °, the speed of sliding block 6 is maximum.Whole experiment process medium velocity can good shape
Into excessive, detecting system is impacted it is small, so the repeated bend test system stability of this steel wire rope and trailing cable is good.
The experimental subjects of the fatigue test system of steel wire rope and trailing cable of the present invention can be elevator traction steel-cable
Or elevator is with traveling flat cable or the steel wire rope or cable in other fields.The outer fixed pulley of this fatigue test system
It can be formed with interior fixed pulley for multiple fixed pulleys of 1 or more, the fatigue test system of steel wire rope and trailing cable of the present invention
Counterweight amount of substance can change different quality according to testing requirements.
The advantageous effects of the fatigue test system of steel wire rope and trailing cable of the present invention are simple in structure, detection sides
Just, stability is good, and low-power machine can reach testing requirements.
The foregoing is only a preferred embodiment of the present invention, is not intended to limit the invention, for the skill of this field
