The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
The utility model comprises anchor cable 8 and the jack 4 that is run through by anchor cable 8 activities, anchor beam 9, tension ground tackle 6, locks ground tackle 1, limiting plate 3.Wherein lock ground tackle 1 and be positioned on anchor beam 9, limiting plate 3 is positioned on locking ground tackle 1, withstands limiting plate 3 by jack 4, and tension ground tackle 6 is on jack 4, and dial gage 7 is arranged on tension ground tackle 6.Limiting plate 3 is the cylindrical-shaped structure that a side has a groove, is provided with some diameters in groove greater than the anchor cable hole of single anchor cable diameter, and the internal diameter of groove is less than the external diameter of locking ground tackle 1.The anchor cable hole that arranges on locking ground tackle 1 is corresponding with the anchor cable hole on limiting plate 3.Anchor clipper 2 is the thin thick conical structure below in top, and the end that anchor clipper 2 is thin is arranged in the anchor cable hole of locking ground tackle 1, and a thick end is arranged in limiting plate 3 upper grooves, and depth of groove is slightly less than the length of anchor clipper 2.Demountable i iron 5 is set between anchor beam 9 and jack 4, and i iron 5 length directly are not pressed on limiting plate jack 4 greater than the length sum of limiting plate 3 and locking ground tackle 1.
Anchor clipper 2 is the thin thick conical structure below in top, and when anchor cable 8 stretch-draw, because frictional force anchor cable intermediate plate 2 moves to the limiting plate direction with anchor cable, anchor cable intermediate plate 2 can not clamp.When stopping stretch-draw, anchor cable 8 retractions, because frictional force anchor cable intermediate plate 2 moves to locking ground tackle direction with anchor cable, anchor cable intermediate plate 2 clamps anchor cables, moves very little displacement anchor cable is clipped in the anchor cable hole of locking ground tackle 1.
I iron 5 is selected the ribbing i iron, and i iron distortion and stressing conditions when then calculating in stretching process maximum pressure according to the mechanics of materials are selected quantity and the intensity of i iron rib steel.Jack is the punching jack, and forming compression system by jack, oil pump and pressure meter is that anchor cable pressurizes.
As shown in Figure 1 and Figure 2, in stretching process, jack 4 is positioned on limiting plate 3 for the first time, and anchor clipper 2 can move freely in limiting plate 3 grooves, guarantees that anchor cable 8 is not locked.For the second time in stretching process, i iron 5 is between anchor beam 9 and jack 4, jack 4 directly is not pressed on limiting plate 3, making limiting plate 3 and lock ground tackle 1 can be freely movable on anchor beam 9, anchor cable 8 is not locked when stretch-draw release for the second time, guarantees that jack 4 equipment such as grade can be easy to dismounting.
Record anchor cable 8 by pressure meter stressed in stretch-draw for the first time, record anchor cable 8 displacements by dial gage 7.When jack 4 reaches stroke, as long as a pressure relief anchor rope 8 gets final product locked ground tackle 1, limiting plate 3 and anchor clipper 2 lockings.Before stretch-draw, then jack 4, tension ground tackle 6 and dial gage 7 dismountings are installed i iron 5 for the second time, i iron 5 one ends are connected with anchor beam 9, the other end contacts with jack 4.Then jack 4, tension ground tackle 6 and dial gage 7 are installed, carry out stretch-draw for the second time after installation, after anchor cable 8 is removed the locking of limiting plate and locking ground tackle, carry out stretch-draw until reach the test requirements document load by code requirement, and when removing the lock pressure of anchor cable the frequent numerical value of recording manometer and dial gage 7.
Carry out in accordance with the following steps the test of long anchor cable tensioning equipment:
A. erection equipment: the locking ground tackle 1 that is passed by anchor cable 8 is placed on anchor beam 9, and anchor clipper 2 is installed, and makes the thin end of anchor clipper 2 be arranged on the anchor cable hole the inside of locking ground tackle 1.Limiting plate 3 passes anchor cable 8 and is placed on locking ground tackle 1, and the fluted end of limiting plate 3 contacts with locking ground tackle 1, makes the thick end of anchor clipper 2 be positioned at groove.Jack 4 passes anchor cable and is connected with limiting plate 3 contacts; Tension ground tackle 6 passes anchor cable and is connected with jack 4 contacts, and anchor clipper 2 is arranged on inside tension ground tackle; Dial gage 7 is arranged on tension ground tackle 6, monitoring anchor cable displacement.
B. anchor cable stretch-draw for the first time: by jack 4 stretch-draw anchors 8,11 oil-feeds of stretch-draw this moment oil cylinder promote stretch-draw piston 12 and move, and record the anchor cable displacement by dial gage 7.In the limiting plate groove, anchor clipper 2 can be freely movable, guarantees that anchor cable is not locked, when the jack stroke reaches near range, stops pressurization, records pressure.Then release, as long as the beginning release, limiting plate 3, locking ground tackle 1 and anchor clipper 2 can lock anchor cable.
C., i iron is installed: dismounting dial gage 7, tension ground tackle 6 and jack 4 after release, then i iron 5 is installed, i iron 5 one ends are contacted with anchor beam 9, the other end contacts with jack 4.Then jack 4, tension ground tackle 6, anchor clipper and dial gage 7 are installed successively.During stretch-draw for the second time, jack directly is not pressed on limiting plate, and limiting plate 3 and locking ground tackle 1 can be freely movable, and when making release, anchor cable is not locked, and equipment can be dismantled.
D. anchor cable stretch-draw for the second time: pressurize after installation, until reach trial load.Will frequently observe in pressure process, record anchor cable bearing pressure and displacement, reach before the locking load, displacement is very little, reaches the displacement change suddenly later on of locking load large.
