Description
Technical field
The utility model relates to environmentally friendly gas sampling technical fields, and in particular to a kind of Pneumatic extension exhaust gas capturing device.
Background technique
The local improvement side for capturing the weld fumes exhaust gas for manufacturing that workshop generates during welding etc. domestic at present
Method mainly has: 1, air suction arm: will welding by the way of the capture of flexible air air suction arm in the place for generating weld fumes pollution sources
Flue dust is taken away, but restricted artificial often according to limits such as bond pad locations adjustment flexible air air suction arm positions with place, air quantity, needs
System, effect are bad；2, fixed top draft hood: will in such a way that the place for generating weld fumes pollution sources is captured using fixed top draft hood
Weld fumes is taken away, but there is the deficiency for influencing large-scale workpiece lifting；3, weld fumes pollution sources fixed side-draught hood: are being generated
Place takes weld fumes away in such a way that fixed side-draught hood captures, but be limited by flue dust diffuse up naturally, the shadows such as wild wind
It rings, effect is bad.
Utility model content
In view of this, making it have structure the purpose of the utility model is to provide a kind of Pneumatic extension exhaust gas capturing device
Simply, the advantages of at low cost, exhaust gas trapping effect is good and will not interfere with work piece hoisting adapts to need to hang for spaces compact
Fill the weld job place of workpiece.
The utility model is solved the above problems by following technological means: a kind of Pneumatic extension exhaust gas capturing device, including
The mobile cover and fixed enclosure being slidably socketed are provided with moving beam on the mobile cover, are provided with cunning on the moving beam
Block, Dust-proof air cylinder, suction opening, interface flange and guide rail are provided in the fixed enclosure, and the piston rod of the Dust-proof air cylinder is logical
It crosses floating junction to connect with mobile cover, the sliding block is slidably connected with guide rail.
Further, the two sides of the mobile cover are provided with moving beam, and sliding block is provided on every moving beam, described
The two sides of fixed enclosure are also respectively arranged with the guide rail being slidably connected with corresponding sliding block.
Further, each sliding block is arranged at the bottom of corresponding moving beam.
Further, centered position is arranged at the top of fixed enclosure in the suction opening.
Further, the exterior contour of the mobile cover is matched with the in-profile of fixed enclosure is slidably socketed.
The utility model has the beneficial effects that the Pneumatic extension exhaust gas capturing device of the application, including the movement being slidably socketed
Cover and fixed enclosure are provided with moving beam on the mobile cover, sliding block, the fixed enclosure are provided on the moving beam
On be provided with Dust-proof air cylinder, suction opening, interface flange and guide rail, the piston rod of the Dust-proof air cylinder passes through floating junction and movement
Cover connection, the sliding block are slidably connected with guide rail.The Pneumatic extension exhaust gas capturing device of the structure, have structure it is simple, at
The advantages of this is low, exhaust gas trapping effect is good and will not interfere with work piece hoisting adapts to be used for spaces compact, needs to lift workpiece
Weld job place.
Detailed description of the invention
The utility model is further described with reference to the accompanying drawings and examples.

Specific embodiment
The utility model is further described below by drawings and examples.Illustrated by these, this is practical new
The characteristics of type and advantage will become more apparent from clear.Obviously, described embodiment is only that a part of the utility model is real
Example is applied, instead of all the embodiments.
Such as Fig. 1-5, shown in Pneumatic extension exhaust gas capturing device, including the mobile cover 1 being slidably socketed and fixed enclosure
5, the exterior contour of the mobile cover is matched with the sealing of the in-profile of fixed enclosure to be slidably socketed, and the two sides of mobile cover are equal
It is provided with moving beam 6, the bottom of every moving beam is provided with sliding block 8, is provided with Dust-proof air cylinder at the top of the fixed enclosure
2, the piston rod of suction opening 3 and interface flange 4, the Dust-proof air cylinder is connect by floating junction with mobile cover, the exhausting
Centered position is arranged at the top of fixed enclosure in mouth, and fixed enclosure is connect by interface flange with extraneous dust collect plant, fixed
The two sides of cover are provided with guide rail 7, and each sliding block is slidably connected with corresponding guide rail respectively, and mobile cover 1 is in sliding block 8 and moves
It under the support of dynamic beam 6, is pushed by Dust-proof air cylinder 2, carries out flexible linear motion along guide rail 7.
During specifically used, when needing to trap exhaust gas, Dust-proof air cylinder 2 pushes the mobile edge out of fixed enclosure of cover 1
Guide rail straight line skids off, and mobile cover is made to be in stretching state, since mobile cover does not block suction opening 3, suction opening 3 again
Naturally it opens, starts to trap exhaust gas by dust collect plant, during trapping exhaust gas, mobile cover and fixed enclosure Ren Ranbao
It stays and partly overlaps or the two is just docked, avoid generating gap therebetween and exhaust gas being caused to leak out from gap, specific shape
State is as shown in Figure 1.When weld job is completed, and is not needed to collect exhaust gas, and is needed to lift workpiece, mobile cover 1 is in anti-dust and gas
Under cylinder 2 acts on, under the support of sliding block 8 and moving beam 6, collapses along 7 straight line of guide rail into fixed overhead guard body, avoid interference with lifting
Operation, particular state are as shown in Figure 2.
In conclusion the Pneumatic extension exhaust gas capturing device of the structure, exhaust gas trapping effect simple, at low cost with structure
The advantages of fruit is good and will not interfere with work piece hoisting adapts to be used for spaces compact, needs to lift the weld job place of workpiece.
Finally, it is stated that above embodiments are merely intended for describing the technical solutions of the present application, but not for limiting the present application, although ginseng
The utility model is described in detail according to preferred embodiment, those skilled in the art should understand that, it can be to this
The technical solution of utility model is modified or replaced equivalently, without departing from the objective and model of technical solutions of the utility model
It encloses, should all cover in the scope of the claims of the utility model.
