Abstract
The utility model relates to a plug-in type bellows mounting structure, which comprises a bushing. One port of the bushing is circumferentially provided with a plurality of elongated gaps. An intubation tube is inserted into the inner wall surface of the bushing. The outer wall surface of the bushing is provided with a clamp. The bottom of the intubation tube is welded with a bellows. The bottom of the bellows is welded with an inlet adapter. The plug-in type bellows mounting structure is compact in structure and convenient in installation and placement. The adapter is large in telescopic compensation amount. Meanwhile, the problem in the prior art that due to the special spatial structure and the special assembly process of a silent-type internal combustion generator, the manufacture of a smoke exhaust pipe can only be realized through the assembly welding process and is time-consuming and difficult in standardization can be solved. The production efficiency of the smoke exhaust pipes of silent-type internal combustion generators is improved and the product quality is stabilized. The assembly process of silent-type internal combustion generators is improved and the adjusting capability of the axial displacement of smoke exhaust pipes is enhanced.
Description
Technical field
The utility model relates to internal combustion engine generator group supplementary equipment technical field, especially a kind of inserting type bellows installation structure for internal combustion engine generator group purging system.
Background technique
Modern society is more and more stronger to the dependence of electric power, and various electric equipments need to have stablizes lasting power supply, especially business, bank, hospital facility.But due to energy scarcity and peak of power consumption undersupply, often have and stop powering-off state.Now internal combustion engine generator group power supply in support, has ensured the normal operation of equipment.But it is very large when the work of internal combustion engine generator group, to produce noise, has directly affected people's work and life.Market is in the urgent need to the as far as possible little mute chamber type internal combustion engine generator group of noise.
Because the baffler in internal combustion engine generator group is often fixed on chassis or casing, when internal combustion engine, produce fierce vibration, subdue by the vibration damper being arranged on chassis, therefore must between internal-combustion engine and baffler, there is individual dampening apparatus---bellows, subdue the compensation of expanding with heat and contract with cold from judder and the smoke-ejecting pipe of diesel engine.
In the market bellows in internal combustion engine generator, apply very general, but most of bellowss adopt flanged connection scheme.But due to silencing type internal combustion engine generator group special structure and mounting process, the smoke-exhaust pipeline of internal-combustion engine can only manufacture weldering, length consuming time, is difficult to standardization.Separately due to the distortion of silencing case, bellows is subject to extra pressure or pulling force and loses or weaken and subdue the compensate function that vibration and smoke-ejecting pipe expand with heat and contract with cold, thereby internal-combustion engine is damaged.
Model utility content
The applicant installs inconvenience, takes over the shortcomings such as flexible compensation amount is little for the oil-electric engine group smoke-ejecting pipe bellows in above-mentioned existing production technology, a kind of inserting type bellows installation structure rational in infrastructure is provided, take over flexible compensation amount thereby increase, simple installation, enhances productivity.
The technological scheme that the utility model adopts is as follows:
A kind of inserting type bellows installation structure, comprises sleeve pipe, and described sleeve pipe one end opening's edge circumferencial direction has the elongated gap of multiple tracks, and described internal surface of sleeve pipe face is inserted with intubate, and the outer wall that is positioned at sleeve pipe is provided with clip; Described intubate bottom welding bellows, described bellows bottom welding entrance sleeve.
Further improvement as technique scheme:
Described sleeve pipe becomes cylindric, and described sleeve pipe adopts Stainless Sheet Steel.
Described sleeve pipe welded top has the first flange.
Described entrance sleeve bottom welding has the second flange.
Described entrance sleeve becomes cylindric, and described entrance sleeve adopts sheet metal.
Distance between described cover infratubal port and bellows seam is a, and the distance between described intubate upper end-hole and sleeve pipe upper end-hole is b, and the distance between described intubate upper end-hole and clip is c, and above-mentioned three's distance equates between two.
The beneficial effects of the utility model are as follows:
The utility model compact structure, install that to put just, take over flexible compensation amount large.Spatial structure and the assembly technology special due to silencing type internal combustion engine generator group are solved, smoke-exhaust pipeline can only manufacture weldering, length consuming time, be difficult to a standardized difficult problem, improve the manufacturing efficiency of mute generator group smoke-exhaust pipeline, stablize quality of product, improve the assembly technology of mute generator group, strengthened the regulating power of smoke-exhaust pipeline axial displacement.
The utility model can be widely used in the vent systems of silencing type internal combustion engine generator group.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Wherein: 1, sleeve pipe; 2, intubate; 3, clip; 4, bellows; 5, entrance sleeve; 6, the first flange; 7, the second flange.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described.
As shown in Figure 1, the inserting type bellows installation structure of the present embodiment, comprises sleeve pipe 1, and sleeve pipe 1 one end opening's edge circumferencial direction has the elongated gap of multiple tracks, and sleeve pipe 1 internal face is inserted with intubate 2, and the outer wall that is positioned at sleeve pipe 1 is provided with clip 3; Intubate 2 bottom welding bellowss 4, bellows 4 bottom welding entrance sleeves 5.
1 one-tenth of sleeve pipe is cylindric, and sleeve pipe 1 adopts Stainless Sheet Steel.Being rolled into cylinder welding by thin plate forms.
Sleeve pipe 1 welded top has the first flange 6.The first flange 6 can be installed according to actual conditions, also can not install.
Entrance sleeve 5 bottom weldings have the second flange 7.The second flange 7 can be installed according to actual conditions, also can not install.
5 one-tenth of entrance sleeves are cylindric, and entrance sleeve 5 adopts sheet metal.Being rolled into cylinder welding by thin plate forms.
Distance between sleeve pipe 1 lower end mouth and bellows 4 seams is a, and the distance between intubate 2 upper end-hole and sleeve pipe 1 upper end-hole is b, represents the axial non-shrinkage maximum collapse regulated quantity of smoke-exhaust pipeline; Distance between intubate 2 upper end-hole and clip 3 is c, represents the axial non-heat expansion maximum extension regulated quantity of smoke-exhaust pipeline, and above-mentioned three's distance equates between two.
Intubate 2 described in the utility model adopts welded pipe, and its cylindrical reaches certain degree of finish and circularity through gold machining.
In actual using process, as shown in Figure 1, the direction of arrow is depicted as exhaust gases of internal combustion engines and flows to, and the second flange 7 places connect internal-combustion engine, and the first flange 6 places are connected with baffler, when pipe arrangement, need to make to equate apart from a, b.When the transport of mute chamber type internal combustion engine generator group, unclamp the clip 3 on grafting bellows 4, when unit is in place, then tighten clip 3.Improve like this manufacturing efficiency of mute generator group smoke-exhaust pipeline, when transport, make bellows 4 avoid extra pressure or pulling force and lose or weaken and subdue the compensate function that vibration and smoke-ejecting pipe expand with heat and contract with cold, thereby internal combustion function is normally moved, extended the working life of internal-combustion engine.
More than describing is to explanation of the present utility model, is not the restriction to model utility, and the utility model limited range, referring to claim, within protection domain of the present utility model, can be done any type of amendment.
