Description
Technical field
The utility model relates to the power engineering wire rope preventive undamaged test system.
Background technology
In the power engineering, wire rope is mainly used in traction overhead stranded conductor, fixedly work such as shaft tower, lifting framework or equipment.It is widely used in the construction, production, maintenance of power engineering, especially in operations such as equipment installation, lifting, dismounting, debugging, uses frequently, and environment of living in is abominable, and it is complicated to bear load.The detection of wire rope is the work of a complexity, often is difficult to accomplish correct damage judgement, and the potential safety hazard that exists is difficult to timely discovery; When serious, wire rope will be in case fracture will jeopardize the person and device security.Engineering with long apart from wire rope one to being regarded as " high-risk member ", the reliability of its carrying will be directly connected to the safety of engineer operation personnel and equipment, safe and reliable state that we can say wire rope enjoys the great attention of administrative authoritys at different levels.Owing to there is not the scientific and reliable checkout equipment, the safe handling of wire rope and operational management problem rest on the primary level all the time but for a long time.Therefore, move applying unit and generally adopt increasing, reduce work efficiency, even the mode of the sacrifice output value ensures the safe operation of wire rope with the rope cost.Nonetheless, sudden rope-broken accident still happens occasionally.Have nearly 35% to cause for wire rope breaking in the engineering construction accident according to statistics.
" power construction trouble free service rules " (DL 5009.1-2002, DL 5009.2-2004, DL5009.3-1997) is the mandatory industry standard of power construction safety in production aspect, it is defined as wire rope--small-sized lifting Work tool, and regulation: the visual examination of engineering steel silk rope, once a day; Internal inspection, every month is once; The preventive trial project is the quiescent load test, and the test period is 1 year.At present, the check of wire rope is all carried out according to the related request of " power construction trouble free service rules ".Make introductions all round below:
1. wire rope visual examination
Every workday all will observe any visible position of wire rope as far as possible, so that find to damage and the situation of being out of shape crucial checkpoint:
A) whether the fracture of wire radical of wire rope in a pitch meets or exceeds the numerical value of setting.
B) cover wire wearing and tearing or corrosion whether reach original steel wire diameter 40% and more than, or whether wire rope burnt by serious annealing or local arc.
C) whether wire rope has wire rope core damage or rope strand to extrude and causes that the rope footpath reduces phenomenon.
D) whether wire rope exists cage shape deformity, seriously twists together or bends phenomenon.
E) whether wire rope has flattening deformation and the serious phenomenon of surperficial burr.
F) steel rope fault quantity is few, but has fracture of wire to increase very fast phenomenon.
G) endless cable of Cha Jieing or rope sling, its grafting length be less than 15 times of diameter, or less than 300mm.
2. wire rope internal inspection
Usually visual examination may can't find the degree of internal damage, so should carry out the internal inspection of wire rope in case of necessity, concrete grammar is:
As shown in Figure 1, be clipped in securely on the wire rope 10 with certain standoff distance, clamp applied a power, make the outer layer strands disengaging wire rope core that scatters towards the direction opposite with cable lay with the clamp 20 of two appropriate sizes.Clamp must not skid around wire rope, and the displacement of rope strand is advisable with visible wire rope core, must not make the rope strand displacement too big.
As shown in Figure 2, will hinder the internal lubrication fat of observation or chip to remove with T type conelet 30 again, observe inner lubricating status, extent of corrosion, fracture of wire situation and because of extruding or the steel wire impression that weares and teares and cause.
After the check, put into an amount of maintenance ointment turning on the position, and rotate clamp with the strength of appropriateness and make rope strand proper reset around wire rope core.Wire rope position behind the removal clamp should be coated with railway grease.
3. wire rope quiescent load test
A) hoisting machinery is installed with the test of wire rope and is seen Fig. 3, will be installed between two voussoirs 40;
Should in the rope sling ring, put into suitable saddle iron (heart type ring) 50 when b) steel wire loop is tested, and be connected with testing machine.
Slowly increase pulling force, make its 2.0 times (wire rope) that reaches rated load or 1.25 times (steel wire loop), keep 10min wire rope (cover).It is qualified that wire rope does not have phenomenons such as breakage, newly-increased fracture of wire, part attenuate.
The safe coefficient that wire rope uses is judged by following items:
A) character of fracture of wire and quantity;
B) end fracture of wire;
C) assemble the part of fracture of wire;
D) increment rate of fracture of wire;
E) rope strand fracture;
F) owing to damaging the rope that causes, wire rope core directly reduces;
G) elasticity reduces;
H) outside and inter deterioration;
I) outside and internal corrosion;
J) distortion;
K) because the damage that heat or electric arc cause.
All checks all should be considered above every factor and follow separately standard.Yet the damage of wire rope is caused by each combined factors accumulation often, and this just should be scrapped or be continued and use by person in charge's differentiation and decision wire rope.
And actual conditions are: three routine inspections of strict enforcement in conjunction with senior reviewer's experience, still can't solve five hang-ups in the wire rope use at present:
Dangerous: wire rope in use lies dormant all the time the danger of rope-broken accident takes place because of loss of intensity.Constitution investigation was once advanced to more than 8000 the wire rope applying unit in the whole world by authoritative research institution of the U.S., and conclusion is: have be in the state of " danger or be in extreme danger " with wire rope 12% or more.
Uneconomical: the periodic replacement wire rope causes great waste.The statistics of the U.S. shows: the wire rope that is forced to more than 70% change seldom or does not basically have loss of intensity.
Inefficient: the efficient that artificial visual, hand are touched inspection is very low.
Unreliable: manual detection can only partly detect the outer damage of wire rope, and to can't with the naked eye detecting wire rope inside, thereby a lot of major accident hidden danger is difficult to find.
Very harmful: rope-broken accident tends to cause great harm, and certain emergency work construction scene causes 2 workers to die at one's post because of the traction steel wire fracture of rope, and adjacent three shaft towers topple.
