Abstract
The utility model discloses a gas rail installation device of a gas engine, belonging to the technical field of the gas engine. The gas rail installation device of the gas engine mainly comprises a fixed bracket used for connecting a gas engine body, and a gas rail mounting bracket used for connecting a gas rail, wherein the fixed bracket and the gas rail mounting bracket are fixedly installed together; the gas rail mounting bracket is provided with two parallel side plates which are opposite to each other; a gas rail mounting plate is arranged between the two parallel side plates, and is parallel to a mounting plane of the fixed bracket; the gas rail mounting plate and the fixed bracket are respectively provided with a connecting rib plate; and the connecting rib plates are parallel to the two parallel side plates. The gas rail installation device of the gas engine solves the technical problem that the service life of an injection valve is short because of large vibration amplitude of a straight gas rail, and can be widely applied to manufacture and use of the natural gas engine.
Description
Technical field
The utility model relates to the gas engine technical field, relates in particular to a kind of gas rail erecting device that is used for the rock gas gas engine.
Background technique
For gas engine, the function of injection valve is that the control fuel gas injection burns in suction tude or firing chamber, and existing mounting structure normally is distributed on injection valve on the gas rail, the gas rail is fixed on the engine body by fixed support again.Like this, just do not have the space to increase the constraint point that is connected with body between four air valves, rely on simply that two bolts hole are connected with body on the fixed support, the connection span is excessive, can cause whole system rigidity very low, thereby cause the fixed support fracture failure.The gas engine that China utility model patent CN201568161U discloses the claimant is with gas rail in upright arrangement, improved support bracket fastened working life to a certain extent, but, in the process of injection valve vibration test, find that gas rail Oscillation Amplitude is big, injection valve is bigger in the gas engine transverse vibration, can not satisfy the vibration usage requirement of injection valve, causes injection valve short working life.
The model utility content
Technical problem to be solved in the utility model is: a kind of gas engine gas rail erecting device is provided, causes injection valve short technical problem in working life greatly to solve gas rail Oscillation Amplitude in upright arrangement.
For solving the problems of the technologies described above, the technical solution of the utility model is: gas engine gas rail erecting device, comprise the fixed support and the air track mounting bracket that is used to be connected the gas rail that are used to connect the gas engine body that are fixedly installed togather, described air track mounting bracket has two relative parallel side plates, be provided with gas rail mounting plate between the described two parallel side plates, described gas rail mounting plate is parallel to described support bracket fastened mounting plane, and described gas rail mounting plate is provided with fixed support and is connected gusset.
As a kind of improvement, described connection gusset is parallel to described two parallel side plates.
After having adopted technique scheme, the beneficial effects of the utility model are: because fixed support and air track mounting bracket are fixedly installed togather, and gas rail mounting plate is provided with fixed support and is connected gusset, it is more firm to make that fixed support is connected with air track mounting bracket, increased the rigidity of air track mounting bracket, reduced the vibration between air track mounting bracket and the fixed support, thereby made injection valve reduce, prolonged the working life of injection valve in the gas engine transverse vibration.
Be parallel to two parallel side plates owing to connect gusset, from the mechanics angle analysis, the connection span of air track mounting bracket reduced, further increased air track mounting bracket rigidity, thereby it is more firm that air track mounting bracket is connected with fixed support, Oscillation Amplitude is littler.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the utility model embodiment's a structural representation;
Fig. 2 is the plan view of Fig. 1;
Among the figure: 1, fixed support, 11, the support mounting hole, 2, air track mounting bracket, 21, gas rail mounting hole, 22, parallel side plate, 23, gas rail mounting plate, 3, connect gusset.
Embodiment
As depicted in figs. 1 and 2, a kind of gas engine gas rail erecting device, mainly comprise the fixed support 1 and the air track mounting bracket 2 that is used to be connected the gas rail that are used to connect the gas engine body that are fixedly installed togather, fixed support 1 is provided with support mounting hole 11, described air track mounting bracket 2 has two relative parallel side plates 22, be provided with gas rail mounting plate 23 between the described two parallel side plates 22, air track mounting bracket 2 is provided with gas rail mounting hole 21, described gas rail mounting hole 21 is positioned on the described gas rail mounting plate 23, described gas rail mounting plate 23 is parallel to the mounting plane of described fixed support 1, and described gas rail mounting plate 23 is provided with fixed support 1 and is connected gusset 3, for the rigidity that makes air track mounting bracket 2 improves, described connection gusset 3 is parallel to described two parallel side plates 22, according to conventional design, according to the span between the two parallel side plates 22, connect gusset 3 and can design one or polylith, to satisfy the actual needs that use.
The utility model is not limited to above-mentioned concrete mode of execution, and those of ordinary skill in the art is from above-mentioned design, and without performing creative labour, all conversion of having done all drop within the protection domain of the present utility model.
Claims (2)
1. gas engine gas rail erecting device, comprise the fixed support and the air track mounting bracket that is used to be connected the gas rail that are used to connect the gas engine body that are fixedly installed togather, described air track mounting bracket has two relative parallel side plates, be provided with gas rail mounting plate between the described two parallel side plates, it is characterized in that: described gas rail mounting plate is parallel to described support bracket fastened mounting plane, and described gas rail mounting plate is provided with fixed support and is connected gusset.
