Abstract
The invention relates to a method for rapidly determining bolt loosening, and especially relates to a rapid point inspection fastening bolt A mark line is drawn on a fastened bolt, and when the mark line is deviated, it is determined that the bolt is loosened. According to the invention, through drawing a continuous line on a point inspection bolt, when equipment runs, the continuous line drawn on the bolt is deviated, it indicates that the bolt is loosened, and then rapid and efficient point inspection can be performed on the equipment, such that the equipment downtime is reduced, repeated operation is reduced, the service life of the bolt is prolonged, the equipment operation time is increased, the production cost is effectively decreased, and cost reduction and efficiency improvement are realized.
Description
Technical field
The present invention relates to a kind of method of quick judgement bolt looseness, particularly relate to the holding bolt of some inspection fast.
Background technology
When at present holding bolt is carried out some inspection fast, mostly adopt spanner fastening point inspection method of operation.
Concrete operation steps: scene needing the screw of some inspection observe, selects spanner after observation in time, after regulating moment of torsion, carry out fastening by ox rice one by one to the screw being selected inspection, the inspection of fastening complete rear just point is complete.
Easy like this cause that screw repeated fastening, it is possible to the damage of bolt, nut can be caused, it is easy to cause bolt to be elongated and deformed, or even the fracture of bolt. The method of such operation had both been lost time, cost of idleness again; Usually also can increase fault handling time, also affect the platform effect of equipment.
Summary of the invention
It is an object of the invention to provide a kind of method of quick judgement bolt looseness, whether the method can loosen by the Timeliness coverage bolt of having put inspection, avoids fault to occur.
Technical solution:
A kind of method of quick judgement bolt looseness, it is characterised in that, fastening bolt draws mark line, when marking line and dislocation occurs, judges that bright bolt loosens.
One embodiment of this invention:
When fastening piece is connected with bolt thread, fastening piece and bolt draw mark line, when equipment is in operational process, when mark line occurs to misplace, illustrate that bolt loosens.
Another embodiment of the present invention:
When fastening piece is fastening by screw rod, nut, screw rod and nut draw mark line, when equipment is in operational process, when dislocation occurs mark line, illustrate that bolt loosens.
To needing, the bolt fastened marks one by one in the present invention.
Described mark line is straight line.
The present invention by drawing continuous linear on a bolt of inspection, when the apparatus is in operation, the continuous linear drawn on bolt misplaces, and bolt looseness is described, equipment can be put inspection fast and efficiently, the minimizing equipment off-time, reduce and repeat operation, extend the work-ing life of bolt, it is to increase operation hours, effectively reduce production cost, it is achieved cost efficiency. Therefore, more than examine marking method and it is worth further applying, it is possible to be applied in every field.
In safety in production effect after utilization: some inspection speed and a quality can be ensured on the one hand, guarantee equipment runs, reduce the number of times that loosened screw phenomenon (causing the tight loosened screw of equipment significant points owing to personnel do not have some inspection to put in place) occurs, avoid equipment due to the loss of the loosening of some screw or screw, cause the overall damage of certain parts or mechanism, avoid cost to waste, reduce the labour intensity of workman, the efficiency of raising equipment, guarantee company completes the production task that group company assigns smoothly; The job safety of equipment and personnel can also be ensured on the other hand, effectively prevent equipment due to the generation of occurring of causing the accident of bolt loosening and other safety problems.
The useful effect of method of this fastening a kind of quick judgement bolt looseness of utilization is: can saving the time on the one hand, save spare part, improve plant efficiency, minimizing is on the impact of other equipment, thus reduces production cost further, it is to increase platform is imitated; Can adequately and reasonably save a time of inspection person's point inspection equipments on the other hand, once inspection can save about 10 minutes, some inspection 2 times every day, cost-saving as follows:
KW-20 power shovel 33156.4 yuan/h �� 0.333h �� 365 day �� 11=44329941 yuan
172 mine truck 15466 yuan/h �� 0.333h �� 365 day �� 40=75192598.8 yuan
12000 yuan, dozer (D10T) platform class calculates (1500 yuan/h-oil expense 480 yuan/h) 2479518 yuan, �� 0.333h �� 365 day �� 11
It it is just 122002058 yuan by the raising operation efficiency creation of value by the above equipment calculating 1 year basic stope.
This labelling method is simple and convenient, invest little, have high repayment, focus on practicality, principle is succinctly understandable, especially has unusual effect in enterprise's cost efficiency, has very strong utilization.
Accompanying drawing illustrates:
Fig. 1 is one embodiment of the present invention schematic diagram;
Fig. 2 is another embodiment of the present invention schematic diagram;
1 screw in figure, 2. marks line.
Embodiment
Embodiment 1
Need the screw 1 select inspection to be undertaken fastening by ox rice one by one at scene, to one by one by standard ox rice fastening complete after screw 1 carry out selection screw rod plane and nut plane. Selection plane will towards outside, mainly in order to convenient mark and the inspection of convenient point, after choosing screw rod plane and nut plane, being marked by the bolt after fastening with red paint or marker pen in screw rod plane and nut plane, we are generally with the position of red paint mark significant points, red paint quick-drying. Marking not significant points with marker pen, label symbol generally adopts the mark line 2 of evenly " one " font, or adopts other symbols. During point inspection next time, we are with regard to the directly red paint of inspection mark, see whether the red paint of " one " font of screw rod plane and nut plane marker line 2 is shifted: mark line 2 is not shifted and illustrates that bolt is fastening; If finding that mark line 2 is shifted to illustrate that bolt has loosening phenomenon, it is necessary to we carry out fastening process in time, to ensure the operation of our equipment high efficiency.
Embodiment 2
Need the screw 1 select inspection to be undertaken fastening by ox rice one by one at scene, to one by one by standard ox rice fastening complete after bolt and fastening piece on draw continuous linear as mark line 2, during point inspection continuous linear no displacement explanation bolt be fastening; If continuous linear finds that displacement illustrates that bolt has loosening phenomenon, it is necessary to we carry out fastening process in time, to ensure the operation of our equipment high efficiency.
