Abstract
The method of wire rope core fusing, comprises the following steps that when filling head the present invention relates to prevent overall breaking force of steel wire rope from testing：1) hemp core in head of steel wire rope after breaking is cut short to the steel wire rope root scattered；2) steel wire scattered around hemp core is surrounded coniform；3) hemp core that will be seen that is wrapped up with exotic material, is filled in the coniform cavity that steel wire is surrounded；4) circular steel plate pad is clamped between the steel wire on the outside of exotic material；5) immersing in liquid zinc head of steel wire rope carries out filling head.Wire rope core is still complete after the method for the present invention makes steel wire rope fill head, and tensile strength is greatly improved when the whole rope of steel wire rope is disrumpent feelings, and the problem from head fracture because wire rope core melts no longer occurs, and breaking force of rope experiment accuracy improves more than 50%.
Description
Technical field
The present invention relates to overall breaking force of steel wire rope experiment, more particularly to one kind prevents overall breaking force of steel wire rope from trying
The method for testing wire rope core fusing when filling head.
Background technology
Steel wire rope is being done when whole rope rupture pull force is tested, it is necessary to two ends be broken, by steel wire one piece, one separates, into circular cone
Shape, is shown in Fig. 1.It is then placed in the liquid zinc of molten state, solidifies it, sees Fig. 2.Whole rope tension machine is then placed in be stretched
Experiment.When steel wire rope is put into liquid zinc, wire rope core is hemp core, and wire rope core would generally melt because of non-refractory, make
Steel wire rope can cause steel cable unbalance stress in the whole rope drawing after filling head because of head wire rope core missing, and accent portion disconnects, and influences steel
The result of the whole rope rupture pull force experiment of cord.
The content of the invention
The technical problems to be solved by the invention are to provide one kind prevents overall breaking force of steel wire rope from testing rope when filling head
The method of core fusing, when solving overall breaking force of steel wire rope experiment, the problem that wire rope core melts during head is filled.Make steel wire rope
Wire rope core is still complete after filling head, with the accuracy of guarantee test result.
To achieve the above object, the present invention is realized using following technical scheme：
The method for preventing overall breaking force of steel wire rope from testing wire rope core fusing when filling head, comprises the following steps that：
1) hemp core in head of steel wire rope after breaking is cut short to the steel wire rope root scattered；
2) steel wire scattered around hemp core is surrounded coniform；
3) hemp core that will be seen that is wrapped up with exotic material, is filled in the coniform cavity that steel wire is surrounded；
4) circular steel plate pad is stuck between the steel wire on the outside of exotic material；
5) immersing in liquid zinc head of steel wire rope carries out filling head.
Compared with prior art, the beneficial effects of the invention are as follows：
Wire rope core is still complete after the method for the present invention makes steel wire rope fill head, and tensile strength is significantly carried when the whole rope of steel wire rope is disrumpent feelings
, no longer there is the problem from head fracture because wire rope core melts in height, breaking force of rope experiment accuracy improves more than 50%.
Brief description of the drawings
Fig. 1 broken for head of steel wire rope after structural representation.
Fig. 2 is the structural representation after head of steel wire rope fills head.
Fig. 3 is the structural representation after wire rope core protection.
In figure：Steel wire rope 1, hemp core 2, steel wire 3, filling zinc first 4, high temperature cloth 5, metal mat 6.
Specific embodiment
Specific embodiment of the invention is further illustrated below in conjunction with the accompanying drawings：
Embodiment 1：
Such as Fig. 3, so that structure 6 × 36WS+IWR diameters 42mm is twisted with the fingers to ZS lay pitch 500mm intensity 1770MPa steel wire ropes as an example,
The method for preventing overall breaking force of steel wire rope from testing wire rope core fusing when filling head, comprises the following steps that：
1) hemp core in head of steel wire rope after breaking is cut short to the steel wire rope root scattered, shorter as far as possible；
2) steel wire scattered around hemp core is surrounded coniform, space formation cavity；
3) hemp core that will be seen that is wrapped up with high temperature cloth, is filled in the coniform cavity that steel wire is surrounded；
4) circular steel plate pad is stuck between the steel wire on the outside of high temperature cloth, the hemp core of parcel is hedged off from the outer world；
5) immersing in liquid zinc head of steel wire rope carries out filling head.
Hemp core is protected and is shown in Table 1 with unprotected whole rope rupture pull force result of the test；
Table 1：
| Tested number | Minimum breaking force standard value | Actual rupture pull force value | Disrumpent feelings position |
| 1 (hemp core is unprotected) | 1110KN | 1052.60 | Rope fills head |
| 2 (hemp core has been protected) | 1110KN | 1118.80 | Rope middle part |
Embodiment 2：
So that structure 6 × 36WS+IWR diameters 36mm is twisted with the fingers to ZS lay pitch 500mm intensity 1600MPa steel wire ropes as an example, steel is prevented
The method of wire rope core fusing, comprises the following steps that when the whole rope rupture pull force experiment of cord fills head：
1) hemp core in head of steel wire rope after breaking is cut short to the steel wire rope root scattered, shorter as far as possible；
2) steel wire scattered around hemp core is surrounded coniform, space formation cavity；
3) hemp core that will be seen that is wrapped up with flameproof fabric, is filled in the coniform cavity that steel wire is surrounded；
4) circular steel plate pad is stuck between the steel wire on the outside of flameproof fabric, the hemp core of parcel is hedged off from the outer world；
5) immersing in liquid zinc head of steel wire rope carries out filling head.
Hemp core is protected and is shown in Table 2 with unprotected whole rope rupture pull force result of the test；
Table 2：
| Tested number | Minimum breaking force standard value | Actual rupture pull force value | Disrumpent feelings position |
| 1 (hemp core is unprotected) | 1000KN | 990.80 | Rope fills head |
| 2 (hemp core has been protected) | 1000KN | 1025.60 | Rope middle part |
