Description
Technical field
The utility model relates to lorry vent gas treatment technical fields, and in particular to the connection for After-treatment technics structure
Frame.
Background technique
With the continuous development of industry, also higher and higher for the requirement of environment, need various industries to improve, with it
Low emission, this three big feature of dependence for inhibiting greenhouse effects and getting rid of to petroleum are objective.Wherein, lorry is as a kind of carrier
, it needs to be effectively treated motor exhaust, to reduce pollution.Meanwhile natural gas vehicle has become Vehicle Industry
Development trend, although the pollution level of the motor exhaust of natural gas vehicle relative to gasoline or diesel engine significantly
It reduces, but with the raising of environmental requirement, it is still necessary to natural gas engine tail gas is handled.
Chinese patent notification number is that CN203296892U discloses a kind of heavy automobile integral LNG engines tail gas disposal
System, including exhaust gas treating device, silencer, exhaust compensator, exhaust brake butterfly valve and connecting pipe, wherein exhaust gas treating device
It is built in silencer front, silencer is built in silencer assembly rear portion；Exhaust pipe leading portion is L shape and guides pipeline into vehicle frame
On the outside of left stringer, exhaust pipe back segment is L shape and guides pipeline into vehicle frame left stringer forward, exhaust compensator, exhaust pipe back segment and
Silencer assembly passes through band respectively and hanger is fixed on the outside of the left stringer of vehicle frame.The advantageous effects of the utility model are
Being not required to change existing structure can be fixed on LNG engines tail gas processing system on vehicle frame, and exhaust gas treating device is with silencer
One, also, it is not necessarily to urea supply, control and spraying system, cost is relatively low.But above scheme has the following problems: should
In exhaust treatment system, silencer assembly is fixed on the left stringer of vehicle frame by band and hanger, since silencer combines
Body itself needs to connect with other components such as exhaust pipes, thus have between silencer assembly and the left stringer of vehicle frame it is certain away from
From distance between the two immobilizes at present, increases to the improved difficulty of engines tail gas processing system.
Utility model content
The utility model is intended to provide the connection frame for being used for After-treatment technics structure, so that silencer assembly and vehicle frame
The distance between left stringer is adjustable, reduces to the improved difficulty of engines tail gas processing system.
In order to achieve the above objectives, the utility model adopts the following technical solution: the connection for After-treatment technics structure
Frame, including L-shaped hanger, transition frame and band, hanger include vertical plate and level board, and at least two peaces are offered in vertical plate
Hole is filled, level board is fixedly connected with transition frame, and band is fixedly connected with transition frame；The vertical cavity offered in vertical plate erects
The upper end of cavity is provided with opening, slide plate is slidably connected in vertical cavity, offered on slide plate multiple limit holes and with peace
The corresponding fixation hole in hole is filled, limit hole is staggered with fixation hole, and the aperture of limit hole is less than the aperture of fixation hole, limit hole
It circumferentially opens up fluted, annular slab is connected with by the first spring in groove, the upper end edge of annular slab is fixedly connected flexible
Pad, the width of elastic cushion are greater than the width of groove, and vertical plate is equipped with the pushing mechanism for pushing skateboarding.
The utility model has the advantages that
1, connection frame is divided into three parts in the utility model, hanger for connect with vehicle frame left stringer, band for
Silencer connection, transition frame is for connecting hanger and band.Meanwhile using transition frame increase the left stringer of vehicle frame and silencer it
Between distance, avoid in vehicle travel process, silencer impinges upon on the left stringer of vehicle frame, reduce vehicle post-processing structure in damage
Wound.
2, vertical cavity is opened up in the utility model in the vertical plate of hanger, slidably connects slide plate in vertical cavity,
It is provided with limit hole on slide plate, when needing to lengthen the length of vertical plate, pushes slide plate sliding to opening direction by pushing mechanism
Dynamic, vertical plate is stretched out in the upper end of slide plate, when limit hole and the position of adjacent mounting hole on slide plate to it is corresponding when limit hole circumferential direction
Annular slab moved under the action of the first spring into mounting hole, the elastic cushion in compressive state start release elasticity, bullet
Property pad is stuck in the outboard end of mounting hole.By the way that slide plate is arranged, fixation hole corresponding with mounting hole is set on slide plate, is increased
The vertical length of hanger reduces engines tail gas processing system convenient for adjusting the distance between silencer and the left stringer of vehicle frame
Improved difficulty.Meanwhile limit hole is set on slide plate, the circumferential setting annular slab of limit hole, using mounting hole and limit hole it
Between relationship increase lockable mechanism without additional convenient for being fixed and limiting to slide plate.Wherein, the upper end edge of annular slab
It is fixedly connected with elastic cushion, the width of elastic cushion is greater than the width of groove, so that locking better effect of the annular slab to slide plate.
3, simultaneously, be staggered on slide plate limit hole and fixation hole so that slide plate both can timely locking, will not shadow
The installation in later period is rung, regardless of whether adjusting the length of vertical plate, the mounting hole in vertical plate is not plugged up.When needing to adjust
When vertical plate length, the part stretched out on slide plate is equipped with fixation hole or limit hole, increases the connection of hanger Yu the left stringer of vehicle frame
Point keeps the connection of the two stronger.
Further, the cross-sectional shape of transition frame is U-shaped, and the both ends of transition frame are fixedly connected with fixed block, the structure ratio
It is stronger, and transition frame connect with band it is more convenient.
Further, adjustment hole is offered on the level board of hanger, adjustment hole is strip-shaped hole, and the upper surface of transition frame is fixed to be connected
It is connected to fixed link, the upper end of fixed link passes through adjustment hole, and the diameter of fixed link is less than the length of adjustment hole, and the structure is adjustable to hang
The distance between frame and transition frame, convenient for being carried out to the horizontal distance between the left stringer of vehicle frame and silencer according to design requirement
It adjusts.
Further, limit hole is located among two neighboring fixation hole.Slide plate slides in and out, the position of limit hole and mounting hole
It is certain to the distance of slide plate slides each when corresponding to, it is measured without additional graduated scale, the distance that slide plate skids off is than calibrated
Really, this is relatively simple for structure.
Further, pushing mechanism includes the adjusting rod for being fixedly connected on slide plate side, and the side of vertical plate offers vertically
Vertical slot is stretched out in the end of slot, adjusting rod, convenient for artificial on the outside by pushing adjusting rod, so that skateboarding, operation side
Just.
Further, one end that adjusting rod is located on the outside of vertical cavity is fixedly connected with elasticity layer, holds convenient for people's hand, increases
Add the comfort level of adjusting rod.
