Description
Technical field
The present invention relates to a kind of spark baffling device, a kind of nuclear power station etc. that is suitable to adapts to the spark baffling device of complex working condition, belongs to safety protection facility technical field.
Background technology
In the Factory Building of the nuclear power station being mounted with various equipment, pipeline or ground, metope, Leak-tight liner surface paint brush etc; for guaranteeing safety; any welding, cut, the fire operation such as polishing is required to carry out protective separation; the generally periphery of getting angry in these regions lays flameproof fabric; to prevent spark from spilling, finished product is caused to destroy or initiation fire.
But, owing under complex working condition, flameproof fabric often cannot on-demand be laid, such as, when periphery has the structural members such as equipment, pipeline, wire casing, it is generally difficult to directly lay flameproof fabric.And for example, it is pointed to hole and faces the steel construction on limit when installing and revise, in place of not accepting flameproof fabric, therefore, it is difficult to reach fire safety demands.
Summary of the invention
It is an object of the invention to: the problem existed for above-mentioned prior art, propose a kind of to dispose flexible spark baffling device, thus be suitable to use under complex working condition, conscientiously meet finished product protection and fire protection requirement.
In order to reach object above, the present invention adapts to the spark baffling device technical scheme of complex working condition: include that two ends have the main chain of fixing device, on described main chain, interval hangs with binding clasp, it is characterized in that: described binding clasp contains upper end and has horizontal support face, lower end forms the clamp of U-shaped draw-in groove, the vertical pull bar of plug-in mounting in the jack in described horizontal support face, described pull bar lower end is connected pressing plate, the inner of described pressing plate is extended and the buckle of described U-shaped draw-in groove make-up clamping flameproof fabric down, it is cased with upper and lower two ends on described pull bar and bears against the stage clip between horizontal support face and pressing plate.
As a further improvement on the present invention, the gib head height of described U-shaped draw-in groove matches with the height of described buckle, is formed and close interval after described buckle and described U-shaped draw-in groove make-up, and the thickness of the described width and described gib head closing interval matches.So, when clamping flameproof fabric, gib head and buckle termination can be distinguished from the bottom to top and from top to bottom pressure holding flameproof fabric, make flameproof fabric form the S-shaped of level and by firm clamping；When the inversion of one of two binding clasps being engaged with another when needs regulation rate of tension, degree of freedom up and down between the two is the most restrained, is the most reliably connected as a single entity.
Further, described main chain two ends connect fixing device by tensioner respectively, and described tensioner includes a pair coaxial sleeve pipe, and described sleeve pipe is by the fixing connection of two root length bars, described sleeve pipe has female thread and is connected with two screw flights respectively, and described screw rod is connected with main chain.Use this structure can carry out tensioning main chain by revoling tube or screw rod.
Further, described fixing device is sucker, and described sucker includes disk, internal stationary annular Magnet.Have magnetic sucker can conveniently adsorb on suitable steel surface near a little of getting angry, if without adsorbable steel surface can by around by this sucker suction on main chain.
Further, described buckle end face and the gib head end face indentation of described U-shaped draw-in groove.Jagged end face can increase the frictional force between binding clasp and flameproof fabric, prevents flameproof fabric landing.
During use, the spark baffling device of the present invention can be conveniently fixed in by sucker and be difficult at hook, when backbone length is slightly rich, suitably regulating by tensioner.Owing to the structure of binding clasp of the present invention can not only reliable retention flameproof fabric, and one of any two binding clasp can engage with another binding clasp after being inverted, therefore when backbone length affluence is more, can be fixed by on-demand rotation any two binding clasp, thus adapt to the use under various complex working conditions flexibly and easily.
In a word, present configuration is reasonable, strong adaptability, more convenient can realize spark isolation reliably, be prevented effectively from mounted finished parts and be destroyed or initiation fire under complex working condition.

Detailed description of the invention
In order to be more fully understood that the present invention, below in conjunction with accompanying drawing, a kind of detailed description of the invention of the present invention is described in detail.
Embodiment one
As it is shown in figure 1, this device includes fixing device 1, main chain 2, tensioner 3, binding clasp 4, on main chain 2, interval hangs with four binding clasps 4.Main chain 2 two ends connect fixing device 1 by tensioner 3 respectively.As shown in Figure 4, fixing device 1 is sucker, including disk 11, and its internal stationary annular Magnet 12.During use, by sucker suction on suitable steel surface near a little of getting angry, if without adsorbable steel surface can by around by this sucker suction on main chain 2.As it is shown on figure 3, tensioner 3 includes a pair coaxial sleeve pipe 31, sleeve pipe 31 is by the two fixing connections of root length bars 32 and has female thread, threadeds with two screw rods 33 respectively.When main chain 2 length is slightly rich, by elongation and the indent of rotary screw 33 adjustable screw, suitably regulate rate of tension.
As shown in Figure 2, binding clasp 4 has horizontal support face 407, the clamp 401 of lower end formation U-shaped draw-in groove 405 containing upper end, the vertical pull bar of plug-in mounting 403 in the jack 406 in horizontal support face 407, pull bar 403 lower end is connected pressing plate 402, the inner of pressing plate 402 is extended and the buckle 409 of described U-shaped draw-in groove 405 make-up clamping flameproof fabric 5 down, and pull bar 403 is cased with the stage clip 404 that upper and lower two ends bear against between horizontal support face 407 and pressing plate 402.The height of U-shaped draw-in groove gib head 410 is identical with the height of buckle 409.During use, as shown in Figure 5 and Figure 6, it is lifted up pull bar 403, flameproof fabric 5 is stretched between U-shaped draw-in groove 405 and buckle 409, releasing lever 403, stage clip 404 promotes buckle 409 to prop up bottom U-shaped draw-in groove 405 thus presses flameproof fabric 5, simultaneously, owing to buckle 409 height is the most identical with gib head 410, pressing plate 402 presses U-shaped draw-in groove gib head 410 under stage clip 404 thrust, so, when clamping flameproof fabric, gib head 410 and buckle 409 termination can be distinguished from the bottom to top and from top to bottom pressure holding flameproof fabric 5, make the S-shaped of flameproof fabric 5 formation level and by firm clamping；Buckle 409 bottom surface and the end face indentation of described U-shaped draw-in groove gib head 410, it is possible to increase frictional force, effectively prevent flameproof fabric 5 landing.
When main chain 2 length is oversize, after one of any two binding clasp 4 can being inverted, engages with another binding clasp 4, to shorten the length of main chain 2, thus adapt to the use under various complex working conditions flexibly and easily.As in figure 2 it is shown, form closing interval 408 after buckle 409 and U-shaped draw-in groove 405 make-up, the thickness of the width and gib head 410 of closing interval 408 matches.As shown in Figure 7 and Figure 8, two U-shaped draw-in groove 405 make-ups, the gib head 410 of each binding clasp 4 snaps in the closing interval 408 of another binding clasp 4 the most just, and the pressing plate 402 of each binding clasp 4 props up bottom the U-shaped draw-in groove 405 of another binding clasp 4.Degree of freedom up and down between two binding clasps is the most restrained, is the most reliably connected as a single entity.
In addition to the implementation, the present invention can also have other embodiments.The technical scheme that all employing equivalents or equivalent transformation are formed, all falls within the protection domain of application claims.
