Description
Technical field
The utility model relates to a kind of mechanical clamp, is specifically related to a kind of for detection of the whether qualified elevator wire rope rupture test fixture of wire rope tensile strength.
Background technology
Wire rope tensile test is to weigh a whether qualified important indicator of wire rope intensity, but WAW-300KN type microcomputer controlled electro-hydraulic servo universal testing machine its from carrying jig because the frequent retaining part wear phenomenon that uses is serious, the phenomenon that there will be wire rope to skid in carrying out wire rope tensile test process or rupture from retaining part, can not make accurate judgement to test findings like this, also impact test and manufacturing schedule.For these phenomenons need a set of accurately, practical, safety, test fixture easily.
Utility model content
The purpose of this utility model is to provide a kind of elevator wire rope rupture test fixture, and it is simple in structure, practical.
For achieving the above object, the technical solution of the utility model is a kind of elevator wire rope rupture test fixture of design, by same material, same specification, form being much of part, lower mutually; Upper, lower include large rope sheave, little rope sheave, clamping plate device and fixed pin; Described large rope sheave is fixed between the left and right clamping plate of clamping plate device, between large rope sheave and clamp device, be provided with lacing hole, the fixed pin being connected with tension tester is equipped with in clamping plate device one end, the cylindrical tangent line of the wiring trench bottom of large rope sheave and fixed pin are on same axis, at large rope sheave edge, be connected with little rope sheave, and the cylindrical of marline wheel wiring groove bottom land cylindrical and large rope sheave wiring trench bottom is in same cambered surface.
Preferably, the large rope sheave diameter of odds ratio of described large rope sheave diameter and wirerope diameter and the ratio large 1 of wire rope nominal diameter.
Preferably, when described wire rope minimum breaking force is less than 125kN, the ratio of described large rope sheave diameter and wirerope diameter equals 20.
Preferably, when described wire rope minimum breaking force is more than or equal to 125kN, the ratio of described large rope sheave diameter and wirerope diameter equals 16.
Preferably, the difference of described large rope sheave wiring groove radius and wire rope nominal radius is more than or equal to 0.25 millimeter.
Preferably, the difference of described marline wheel wiring groove radius and wire rope nominal radius is more than or equal to 0.25 millimeter.
During sample, by upper and lower respectively the fixed pin by be separately assemblied on elevator wire rope rupture test machine, adjust crossbeam height, distance adjustment between upper and lower is suitable, wire rope sample on the large rope sheave of upper around Liang Quan, then on the little rope sheave of upper around a circle, then fag end is extracted from wire rope.With same manner on the large rope sheave at lower wire rope sample around Liang Quan, then on the little rope sheave of lower around a circle, then another fag end is extracted from wire rope.Experiment starts front tension two fag ends, hands taut to unclamping non-slip just can the beginning of hand and tests.Along with the increase of pulling force, the wire rope being clipped in large rope sheave wiring groove is drawn tighter and tighter, until last wire rope is pulled off, completes test.
The cylindrical tangent line of large rope sheave wiring trench bottom and fixed pin are on same axis, and the cylindrical of marline wheel wiring groove bottom land cylindrical and large rope sheave wiring trench bottom is in same cambered surface.Center of effort's line of wire rope is overlapped with testing machine center line, thereby guaranteed the accurate, reliable of test findings.
Advantage of the present utility model and beneficial effect are: a kind of elevator wire rope rupture test fixture is provided, and it is simple in structure, practical.
This breaking force of rope test fixture is wrapped in wire rope sample to be wound around and to compress on test fixture and reaches the fixedly object of wire rope in process of the test, this damages wire rope in clamping process to avoid fixture, and the wire rope phenomenon of skidding, thereby reliability and the accuracy of test have been improved, greatly shorten test period, there is larger using value.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of part or lower on the utility model.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is further described.Following examples are only for the technical solution of the utility model is more clearly described, and can not limit protection domain of the present utility model with this.
The concrete technical scheme of implementing of the utility model is:
As shown in Figure 1, a kind of elevator wire rope rupture test fixture, by same material, same specification, form being much of part, lower mutually; Upper, lower include large rope sheave A, marline wheel B, clamping plate device C and fixed pin D; Described large rope sheave A is fixed between the left and right clamping plate of clamping plate device C, between large rope sheave A and clamp device, be provided with lacing hole, clamping plate device C is equipped with one end the fixed pin D being connected with tension tester, the cylindrical tangent line of the wiring trench bottom of large rope sheave A and fixed pin D are on same axis, at large rope sheave A edge, be connected with marline wheel B, and the cylindrical of marline wheel B wiring groove bottom land cylindrical and large rope sheave A wiring trench bottom is in same cambered surface.
The odds ratio large rope sheave A diameter of described large rope sheave A diameter and wirerope diameter and the ratio large 1 of wire rope nominal diameter.
When described wire rope minimum breaking force is less than 125kN, the ratio of described large rope sheave A diameter and wirerope diameter equals 20.
