Technical solution：The circumferential direction in order to solve the above technical problems, large-scale steel bridge cable member Double-layer flexible of the invention explodes
Cutter device, including semicircular first shell and second shell, first shell and second shell are equipped with attachment device, pass through
First shell and second shell are connected into a full circle by attachment device, and half is mounted in the first shell and second shell
Circular first cutter is equipped with detonator hole on the first cutter, is equipped with detonator in detonator hole year；First cutter is put
Enter in first shell and second shell, first shell and second shell are fixed on cable body by attachment device, and ignite detonator, thunder
Pipe ignites the first cutter, and the first cutter generates jet stream and cuts cable body.
Preferably, being additionally provided with semicircular second cutter, the second cutter in the first shell and second shell
Between the first cutter be equipped with limit plate, by limit plate by the first cutter and the second cutter be fixed on first shell and
In second shell, it also is provided with detonator hole on the second cutter, detonator is installed in detonator hole, detonator selects digital electric detonator.
1 piece of digital electric detonator being respectively provided in two cutters, the burst time is set as 1ms, it is ensured that two layers of cutter detonates simultaneously, and two
Layer cutter jet stream is formed simultaneously, and since the distance apart from cable is different, is successively cut to cable, is considerably increased and cut
Cut depth, at least the 1.5 of single layer cut depth times.
Preferably, the attachment device is the first boss and second boss extended in first shell and second shell,
First boss and second boss, first boss and second boss include the folder platform of semicircular ontology and the extension of ontology both ends,
It presss from both sides platform and is equipped with through-hole, bolt is installed in through-hole, first shell and second shell are clamped on cable body by bolt.
Beneficial effect：The circumferential cutter device of large-scale steel bridge cable member Double-layer flexible explosion of the invention, is gathered using linear
Energy cutter carries out Cut blasting to cable member, and the explosive needed is relatively fewer, and blasting cut is regular, powder charge setting letter
Just, secondary harm effect is small.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention.
Fig. 2 is the overlooking structure diagram of Fig. 1.
Specific embodiment
The present invention will be further explained with reference to the accompanying drawing.
As depicted in figs. 1 and 2, the circumferential cutter device of large-scale steel bridge cable member Double-layer flexible of the invention explosion, including
Semicircular first shell 1 and second shell, first shell 1 and second shell are equipped with attachment device, will by attachment device
First shell 1 and second shell connect into a full circle, and semicircular is mounted in the first shell 1 and second shell
One cutter 2 is equipped with detonator hole on the first cutter 2, is equipped with detonator in detonator hole year；First cutter 2 is put into
In one shell 1 and second shell, first shell 1 and second shell are fixed on cable body 5 by attachment device, and ignite detonator, thunder
Pipe ignites the first cutter 2, and the first cutter 2 generates jet stream and cuts cable body 5.
In the present invention, it is additionally provided with semicircular second cutter 4 in the first shell 1 and second shell, second cuts
It is equipped with limit plate 3 between cutter 4 and the first cutter 2, is fixed on the first cutter 2 and the second cutter 4 by limit plate 3
In first shell 1 and second shell, it also is provided with detonator hole, detonator being installed in detonator hole on the second cutter 4, when in use,
Two root detonators ignite simultaneously, and two cutters work at the same time.
In the present invention, the attachment device is that the first boss extended in first shell 1 and second shell and second are convex
Platform, first boss and second boss, first boss and second boss include semicircular ontology and the folder that ontology both ends extend
Platform, folder platform are equipped with through-hole, are equipped with bolt in through-hole, first shell 1 and second shell are clamped in cable body 5 by bolt
On.
In the present invention, cable body is the parallel wire unit of slightly twisting, and small torsional angle makes performance of the drag-line with Self-fastening, together
When be convenient for again be bent sabot transport.One or more layers HDPE sheath of outside hot extrusion, both ends are cold cast upset head anchor.Cable member structure
Complexity, but main composition has steel strand wires cable body and sheath.Steel strand wires cable body belongs to flexible structure, has high intensity, high resiliency mould
The characteristics of amount and anti-fatigue performance；Sheath belongs to rigid structure, has the features such as high intensity, good corrosion resistance.It utilizes
The device of the invention, the first cutter 2 and the second cutter 4, which are usually pressed or are cast by high explosive, dresses up type.Metal cap is by wedge
Shape or the semicircle materials such as steel or red copper are stamped to form.Linear Matrix Inequality approach uses end detonation mode, and detonation product squeezes gold
Belong to cavity liner, forms " blade " shape jet stream, tip speed is up to 4000m/s or more.It is cut when using the first cutter 2 and second
After cutter 4, the first cutter 2 first generates " blade " shape jet stream, acts on cable first, cuts to cable, and rear second
Cutter 4 generates " blade " shape jet stream, is further cut to the steel wire in no thorough cable of cutting.First cutting
The depth of cut of device 2 and the second cutter 4 is mainly related with the performance of explosive in the first cutter 2 and the second cutter 4, no
To explosive payload number it is directly proportional, after explosive determines, the depth of cut range of cutter has been determined, in identical explosive payload
In the case of, using the first cutter 2 and the second cutter 4, action cables, depth of cut are at least the 1.5 of same explosive payload together
Times, considerably increase the depth of cut of cutter device.
