It is detached from.Fixed briquetting 12 and lower fixed briquetting 14 are steel material.Soil is supported, test pipe 10 is embedded in soil
In earth basis 13, different depth is buried according to different experiment demands.
Part III is junk and hangs a liter relieving mechanism.As shown in fig. 7, junk group 9 hangs lift, hanger rope 5 by the offer of hanger rope 5
It ties in suspention button 95, is welded on fixed press strip 94.Fixed press strip 94, multilayer Weight plate 96 and guide plate with holes are by fixing
Stud 92 and fixing nut 93, which are anchored on junk contact 97, forms junk group 9, wherein the junk contact can have not similar shape
Shape can form the different contact shapes such as plane contact, line contact, sphere-contact, cusp contact.Guide rod 4 passes through guide plate
91 hole carries out junk group 9 limit in horizontal plane, to control posture when 9 bump test pipeline 10 of junk group.Guide rod
And hang liter structure and extended from guide ring 41 to both sides as shown in figure 4, being oriented to crossbeam 42, guide rod 4 is connected, the guide ring 41 is outstanding
It is hung on suspention block 6 and can rotate about to different angle.Suspention block is fixed on 3 top of test tower, and lower part is connected with fixed pulley 71.
3 top corners of test tower are provided with another pulley chunking 7, including are fixed on 3 link block 72 of test tower and its underpart fixed pulley
71.Hanger rope 5 is connected to junk group 9 and lifting spool 8 by two fixed pulleys 71 respectively.Shaft 8 is lifted by crane as shown in fig. 6, shaft
82 suspended spans can drive shaft 82 at 81 both ends of fixed frame by rotating handle 86.Conventional baffles 83 and gear baffle 84 are fixed on
Shaft 82,5 one end of hanger rope bolt in shaft 82, rotate tightening with shaft 82 or loosen hanger rope 5.85 one end of strip is articulated with examination
Tower 3 is tested, the other end can be at any time stuck in when shaking rotating handle 86 on gear baffle 83, fixed hanger rope current location.Hanger rope 5 is released
Lock is put as shown in figure 5, being arranged at 5 predetermined length of hanger rope.Hanger rope 5 is connected on upper lift ring 51 and lower lift ring 53, spiral shell
Nail 52 is each passed through two hanging rings, is fastened by nut 54.By the way that multiple releasable catch are arranged, change lock releasing position, it can be with
Effectively 9 height of drop of control junk group.
Illustrate the implementation process for hitting simulation experiment system than ruler submarine pipeline junk entirely below in conjunction with the accompanying drawings:
(1) test pipe 10 is positioned in scheduled experimental basis, is fixed by different positioning attachments, such as schemed
Shown in 2.Above nigration tower 3 to targeted test pipeline 10.Assembled junk group 9, selects junk of different shapes as required
Contact 97 adds the Weight plate 96 of different number, and be tightened stud 92 and fixing nut 93, and guide rod 4 is inserted into guide plate
In 91 hole.It checks the releasable catch on hanger rope 5, ensures that it is in tightening state.Fasten 5 one end of knot hanger rope to suspention button 95, separately
Lifting spool 8 is fixed in one end.It is appropriate to shake rotating handle 86, so that hanger rope 5 is lifted junk group 9 slightly.Finely tune test tower 3
Position, junk contact 97 is placed in right over test pipe 10, guide rod 4 and junk group 9 are adjusted to scheduled by rotation
Deflection angle.
(2) it after the completion of waiting for the above process, shakes rotating handle 86 and rolls hanger rope 5, junk group 9 is promoted to predetermined altitude,
Occurred level face does not rotate guide rod in the process.The releasable catch of corresponding position falls to 8 top of lifting spool in hanger rope 5, stops
Rotating handle 86 is only shaken, blocks gear baffle 84 with strip 85, holding system remains static.
(3) after the completion of waiting for the above process, the connection of screw 52 and nut 54 in releasable catch is unclamped, is pulled out in being buckled from hanging ring
Screw 52 makes upper lift ring be separated with lower lift ring, and the movement of falling object occurs under the effect of gravity for hanging object group 9, along scheduled level
Test pipe 10 below angle bump test tower 3 completes this junk knockout process.
