The specific embodiment
The present invention is further described below in conjunction with drawings and Examples.
The disconnected anchor clamps that expand of part natural section faying face, comprise the disconnected beam 2 that expands, the following disconnected beam 9 that expands, go up the disconnected beam 2 that expands, be provided with the disconnected pull bar 6 that expands between the bloated disconnected beam 9 down, go up the disconnected beam 2 that expands, be respectively equipped with the fault block 3 that expands on the bloated disconnected beam 9 down, the both sides of bloated disconnected pull bar 6 are provided with the disconnected platform 17 that expands, the end face I 16 of bloated fault block 3 is tangent with the end face II of the disconnected platform 17 that expands, and end face I 16 all has inclination angle and relative with the end face II.
The fault block 3 that expands is fixed on expand disconnected beam 2 and the disconnected beam 9 that expands down by bolt 5 and nut 4;
The disconnected beam 2 that upward expands is decided slip-knot bearing pin 11 with a following bloated end utilization of breaking beam 9 and is concluded that with expanding slip-knot 10 links to each other, and the effect that anti-fastening slip-knot bearing pin 11 comes off is played in split pin 12.The disconnected pull bar 6 that expands is connected with the disconnected moving slip-knot 7 that expands by moving slip-knot bearing pin 8.
The disconnected method that expands of the disconnected anchor clamps that expand of above-mentioned natural section faying face, the whole processing parts 1 of elder generation, treat the welded flange of both sides up and down 14 of bloated section at part 1, treating bloated section part processing spalling groove 13, in the left and right sides of part 1 the disconnected anchor clamps that expand are installed again then, are spurred the disconnected pull bar 6 that expands, make that an end of part 1 is first along 13 spallings of spalling groove, form crackle and expand to the other end along the spalling groove, finally expand disconnectedly, form two parts that have the concavo-convex section faying face 15 of nature.
Expand when breaking, spur the disconnected pull bar 6 that expands, the effect of disconnected platform 17 and bloated fault block 3 owing to expand, make and go up the disconnected beam 2 that expands, the following disconnected beam 9 that expands away from the other side, because the end face angle difference of each bloated fault block 3, the distending speed of feasible disconnected beam one end that expands has promoted the disconnected efficient that expands greater than the other end, makes part along 13 spallings of spalling groove.
Concrete steps are, at first at the relevant position of one-piece parts 1 welding mounting flange 14, flange 14 is welded in the both sides for the treatment of bloated section, the welding position is as the criterion can put into the disconnected anchor clamps that expand, and is waiting the disconnected position processing spalling groove 13 that expands then, and spalling groove 13 is waited one week of section faying face of expanding along part, use the disconnected anchor clamps that expand subsequently, form crackle and expansion along spalling groove 13, final spalling makes part 1 form two parts of the concavo-convex section faying face 15 of nature.
The disconnected anchor clamps that expand comprise the disconnected beam that expands, the disconnected beam that expands is divided into expand disconnected beam 2 and the disconnected beam 9 that expands down, go up on expand disconnected beam 2 and the disconnected beam 9 that expands down and be respectively arranged with the fault block 3 that expands, wherein the end face I 16 inclination angle angles of each bloated fault block 3 have nothing in common with each other, be mounted on the disconnected beam that expands according to the fault block 3 end face inclination angle size orders that expand, the minimum end face inclination angle of the fault block 3 that wherein expands is 2 °, and maximum end face inclination angle is 5 °, the quantity of the fault block 3 that expands rationally is set, evenly arranges installation.
Embodiment referring to Fig. 1-Fig. 9, is waiting the disconnected part 1 processing spalling groove 13 that expands, and at the welded flange 14 on the disconnected part 1 of waiting to expand of spalling groove 13 both sides, the distance between the flange 14 is as the criterion can put into the disconnected anchor clamps that expand.The bloated anchor clamps that break mainly are made up of the last disconnected beam 2 and following bloated disconnected beam 9 and the disconnected pull bar 6 that expands of expanding.The disconnected anchor clamps that expand are installed respectively in part 1 both sides, end utilization that to go up expand disconnected beam 2 and the disconnected beam 9 that expands down after installing is decided slip-knot bearing pin 11 and is concluded that with bloated slip-knot 10 links to each other, expand and conclude that slip-knot 10 is provided with through hole, be convenient to fix, the disconnected pull bar 6 that expands is arranged in the middle of expand disconnected beam 2 and the disconnected beam 9 that expands down, the bloated fault block 3 and the disconnected platform 17 that expands on the disconnected pull bar 6 that expands that go up to expand on disconnected beam 2 and the disconnected beam 9 that expands down are corresponding one by one, and it is consistent to be mainly reflected in the break end face II inclination angle of platform 17 of expanding of end face I 16 inclination angles of the fault block 3 that expands and its correspondence.
During spalling, to expand and conclude that slip-knot 10 is fixed on the operate outside platform, spur the disconnected pull bar 6 that expands, fault block 3 and the disconnected platform 17 that expands have the inclination angle owing to expand, therefore feasible bloated disconnected beam 2 and the following bloated beam 9 that breaks move in opposite directions, can form a power that outwards expands, because each bloated fault block 3 and bloated fault block end face I 16 inclination angles have nothing in common with each other, conclude that from bloated slip-knot 10 1 ends to bloated fault block end face I 16 inclination angles of the bloated fault block 3 of disconnected moving slip-knot 7 one ends that expands increase successively, making waits to expand breaks part 1 near the first spalling of disconnected moving slip-knot 7 one sides of expanding, form the concavo-convex section faying face 15 of nature, the part of having no progeny that expands wants strict pairing to use, the disconnected faying face part that expands can be applicable to complex environment, can reduce shear stress, and the antivibration ability is stronger.
The bloated naturally disconnected section faying face of the present invention is formed by spalling, is concavo-convex naturally state, and effectively bonded area is big, good seal performance.
The bloated naturally disconnected section faying face of the present invention is rough and uneven in surface, and it is tight to fit, and can stop faying face to produce relative slippage, has reduced bolt clippers shear force.
The bloated naturally disconnected section faying face of the present invention can be resisted local small deformation, reduces moisture and enters, and has overcome the faying face generation corrosion phenomena that prior art exists, but the service life of elongated component.
