Description
Technical field
The present invention relates to a kind of load-carrying properties test device and method, annular that especially a kind of mine suitable for coal mine is mining
Wirerope load-carrying properties test device and method.
Background technique
Annular wire rope, also referred to as closing endless steel cable, are usually applied to the overhead manned equipment of coal mine, belong to electrodeless
Restrict transportation system, is the most frequently used equipment of the oblique transport personnel in mine or more.Annular wire rope is led as the power of transportation system
Draw unit, is the key that can endless-rope system steadily be safely operated.Under motor or hydraulic motor effect, open in advance
Tight annular wire rope recycles winding constantly between driving wheel and return sheave, this also results in annular wire rope and is prone to break
The failures such as silk, diameter diminution." safety regulations in coal mine " regulation, for preventing steel wire rope of overhead passenger at least inspection 1 time weekly, when
The ratio between fracture of wire basal area and steel wire total basal area are more than 10% in 1 lay pitch or wirerope diameter compares steel wire for wirerope
When nominal diameter of restricting reduces 10%, then wirerope is scrapped, it is necessary to more change steel rope.Before the new rope of installation, new rope, which should be avoided, reduces fortune
Defeated system hauling ability, causes great security risk.In addition, overhead manned equipment is set as the coal mine of long-term continuous operation
It is standby, it changes rope and needs to interrupt personnel's transport.If changing discovery after rope to need to reprocess, it will result in significant economic losses.Therefore, In
Before renewing rope, need to carry out wirerope stringent load-carrying properties test.
Currently, annular wire rope production firm is numerous, the manufacturing process and production standard of use are not quite similar, and load
It can test one unified device of shortage.Due to coal mine output difference, tunnel form of diverse, the personnel amount of miner and flowing frequency
Rate is different, produces different demands to tractive force size and hauling speed, thus generates the overhead man-riding dress of different winding radius
It sets, causes to be difficult to take unified device to the performance test of annular wire rope, and be directed to the ring like steel wire of different winding radius
Rope builds test device respectively, it will generates higher construction and operation cost, is unsatisfactory for cost-effectiveness requirement.Currently, wirerope
Factory testing, it is main to carry out straight line tension-torsion test using to wirerope, or steel wire is broken, bending and torsion are surveyed
Examination, and load-carrying properties test of the wirerope under different winding radius cannot be effectively carried out, it not can accurately reflect wirerope
Bearing capacity.
Active Service is detected currently, being concentrated mainly on to the detection research of annular wire rope, such as Patent No.
Mine overhead passenger device wirerope line flaw detection device disclosed in ZL201410480749 sequentially passes through flaw detection using wirerope
Magnetizer and flaw detection sensor detect annular wire rope failure；Continuous rope quality disclosed in Patent No. ZL201520030246
Can comprehensive measurement device be to bear maximum tightening force by detection wirerope to judge Quality of Steel Wire Rope quality.However, at present
The studies above can not detect the annular wire rope of different winding diameters, and it is compacted to simulate the wirerope enclosed in packet arc
Dynamic process, can not accurately test the load-carrying properties such as wirerope tension, fatigue life.Thus, it is necessary to study a kind of test dress
Set, can the annular wire rope load-carrying properties to different winding radius test, the tensile capacity of accurate evaluation wirerope and
It is fatigue life, unified before being installed at the scene so as to the different model wirerope produced to each manufacturer to check, ensure mine continuous rope
The safety of transportation system, and lack corresponding test device at present.
