Description
Technical field
The present invention relates to a kind of support means, particularly to a kind of tension test for anchor support means for horizontal tensile testing machine,
Belong to horizontal tensile testing auxiliary device technical field.
Background technology
Along with boats and ships increasingly keep the large-scale development, the performance of craft tug is more and more excellent, and the tugboat condition that harbour is equipped with more is come
The most perfect, captain and pilots rely primarily on tugboat and have assisted to lean on from pool operation, and anchor is the important tool in Ship Controling,
Being the key element of safety operation boats and ships indispensability substantially, anchor also has purposes widely in the most medium and small Ship Controling of Ship Controling.
Anchor purposes in Ship Controling is broadly divided into: pool anchor, port wife's behaviour's anchor and emergency maneuver anchor three major types.Therefore,
Can the intensity of anchor reach requirement, and the safety for boats and ships is most important.
Pull test is the experiment that anchor have to be carried out before dispatching from the factory.According to the requirement of national standard, draw when carrying out pull test
Power is respectively acting on a certain ad-hoc location unloading buckle and anchor fluke of anchor, additionally to measure anchor pole end before and after drawing examination respectively and arrive
The distance of anchor point.Existing research technique is prefabricated anchor hole on ground, is hooked in by the anchor fluke of anchor to be tried in anchor hole, then uses
Puller system applies required pulling force to anchor.It is variant by angle, the shape of various anchors, it is therefore desirable to prefabricated different specification anchor hole,
And this set assay device can only carry out the test of anchor, thus utilization ratio of device is low, and experimentation cost is high；Additionally due to cannot realize
Measure the anchor pole end distance to anchor point while pull test, therefore need to mark a little on present anchor pole and anchor point before the test,
And by manually distinguishing the distance between measurement markers point after before the test, therefore test efficiency is low, hand labor intensity is big.

Embodiment
Due to the anchor of dissimilar anchor pointed shape size shape difference, power effect position difference, therefore positioning fixture needs according to these
Difference carries out suitable replacing.Between different positioning fixtures 5, shape is much the same, and difference is that the size of entirety can be along with anchor
The point difference of size and different, the boss of location-plate 5-1 can along with anchor point with or without boss difference, and the arc of location-plate 5-1
The position of shape groove adjusts according to power effect position difference.
Below for the SC/T 8009-2000 test requirements document to two fluke anchors, anchor testing support means is operated.
Anchor testing support means is placed in (see figure 1) on the guide rail 9 of horizontal tensile testing machine, adjusts examination by roller 8
Experiment device is in the position of tensile testing machine.According to the length of anchor 10 to be measured, by boss seat 2 and the second lowering or hoisting gear 4 in T-slot
Move in 8, make the distance between first, second lowering or hoisting gear 3,4 be suitable for the length of anchor 10 to be measured.Anchor 10 to be measured is placed on
In anchor testing support means, wherein anchor bill is placed on the first lowering or hoisting gear 3, unloads end of thread and is placed on the second lowering or hoisting gear 4, will
Positioning fixture 5 is placed on the anchor point of anchor 10 to be measured, and is fixed on anchor point by tightening clamping screw secondary 5-2.Adjustment first,
The height of the second lowering or hoisting gear 3,4, makes the arcuate groove in the location-plate 5-1 of positioning fixture 5 with shackle in the same horizontal line,
At 1/3rd of the anchor fluke of anchor 10 the most to be measured and shackle in the same horizontal line.The anchor pole of anchor shackle end disposes range unit
6, and laser range sensor 6-3 is installed in adjusting means 6-2 of magnetic bases 6-1, the angle adjusting adjusting means 6-2 makes
The laser alignment anchor point of laser range sensor 6-3.In the arcuate groove steel loading cord of the location-plate 5-1 upper surface of positioning fixture 5,
Simultaneously load onto steel wire rope unloading end of thread.Tensile testing machine starts steel wire rope imposed load.
Tensile testing machine applies the test load of 10% to steel wire rope, protects and carries 5min, more gradually applies to 100% test load,
Protect and carry 5min, then be offloaded to value record, the root of laser range sensor 6-3 in the 10% test load whole process of the test of reading
According to requiring that judgement anchor 10 is the most qualified.
Anchor 10 is revolved turnback, repeats a upper process of the test.
In above-mentioned process of the test, in order to make anchor testing support means only play a supportive role, and tension test for anchor is not produced impact,
First, second lowering or hoisting gear 3,4 need to be finely adjusted, make slightly below to unload at the arcuate groove in the location-plate 5-1 of positioning fixture 5
The shackle of end of thread.When tensile testing machine is to anchor 10 imposed load, the front end of anchor 10 can slightly be lifted, and makes support means not be subject to
Power, thus do not affect result of the test.
