Description
Technical field
The invention belongs to steel wire properties detection device field, it is related to detection fixture, and in particular to a kind of rope cramp
Hold method.
Background technology
Steel wire rope has good bending pliability and bearing capacity, thus is widely used as the tracting cable of Transport Machinery
Rope, the lifting hawser of mining machinery, support hawser, the bearer cable of cable-stayed bridge of manned ropeway etc., the bearing strength of steel wire rope
It is all extremely important for the safe operation of these application equipments with service life.In the running of these equipments, steel wire rope
Stretching and bending and dynamic load repeatedly is subjected to, makes inside steel wire rope between each stock, be subjected to not between steel wire and steel wire
With the fretting wear of fretting amplitude, and still suffer from alternate stress.Less fretting amplitude often causes steel wire fretting to connect
Crack initiation, extension and the fracture in area are touched, fretting fatigue is formed, aggravates the fatigue rupture of steel wire rope.Fretting fatigue is used as fine motion
One of Three models of damage, are the fatigue ruptures under the influence of fretting damage, are compounded with fretting wear and axial fatigue, seriously
Influence the fatigue strength of steel wire in steel wire rope.
Therefore, need to carry out steel wire rope performance one preliminary test test when steel wire rope is used for into all kinds of industries, and
Wire cable clamp then plays the key factor of influence steel wire rope performance in test process.
Step up degree in the prior art in order to improve steel wire rope, to the research of fixture retrieval section achievement.
In patent（CN 201120404556.9）In disclose a kind of overall breaking force of steel wire rope experiment coiling fixture；
Including the big rope sheave being fixed between the left and right clamping plate for clamping panel assembly, lacing hole is provided between big rope sheave and clamping device,
Clamp panel assembly one end and the steady pin being connected with tensile testing machine, the cylindrical tangent line of the wiring trench bottom of big rope sheave and fixation are housed
Pin on the same axis, small rope sheave is connected with big rope sheave edge, and small rope sheave wiring groove bottom land is cylindrical and big rope sheave is around grooving
Bottom it is cylindrical in same cambered surface.But the fixture is only suitable for one section of steel wire rope of interception and carries out rupture pull force experiment, it is impossible to
Realize that whole spooling takes section to carry out nondestructive safety on line experiment at random, and steel wire rope whole must enclose and be wrapped in rope sheave
On, especially for generous wire-diameter steel rope, test operation is complicated.
In patent（CN 201120541577.5）Disclosed in come a kind of breaking force of rope test fixture, the patent
In process of the test by wirerope-winding in winding groove, steel wire rope head is compressed by artificial screwing bolts, nut, fixation is reached
The purpose of steel wire rope, and then carry out the rupture pull force experiment of steel wire rope.The patent is equally only suitable for intercepting one section of steel wire rope
Carry out rupture pull force experiment, it is impossible to realize that whole spooling takes section to carry out nondestructive safety on line experiment at random, and twine
Around with clamping by artificial operation, less efficient, clamping is not sufficiently stable.
In patent（CN 201210297986.4）In disclose a kind of clamp of steel wire rope tension test machine, the patent passes through
Expanding force when guide pad arc-shaped slot on upper and lower fixture undertakes steel wire rope sample tensile test, makes steel wire rope sample fracture exist
Centre position, it is to avoid the problem of steel wire rope broken end appears in retaining part and makes test failure.The patent is still simply adapted to
Rupture pull force experiment is carried out in one section of steel wire rope of interception, is primarily adapted for the pull test of micro-, thin shaped steel wire rope.
In patent（CN201310348103.2）In disclose a kind of Zero damage multifunctional steel wire rope tension tester fixture,
Including a base, at least one dynamic clamping claw being driven by the cylinder is installed on described base and fixed with least one
Clamp tool jaw on base, described dynamic clamping claw and determine to form the tubular of confession steel wire penetrating between clamping claw
S types space.But it is only applicable to 15-30mm steel wire rope.
