Abstract
The utility model provides an integrated high exhaust pipe comprising a muffler. Two ends of the muffler are connected with an intake pipe and an exhaust pipe respectively, a support used for installation and fixation is arranged at the tail end of the intake pipe, and a reinforcing rib is arranged between the support and the muffler. High-temperature loud-noise exhaust gas generated by a forklift engine flows to certain height via guidance of the intake pipe, then enters the muffler to be subjected to denoising treatment and then is exhausted to upper atmosphere through the exhaust pipe, so that influence of noise on environment and human bodies is reduced, and volume of the muffler is increased while muffling effect of the same is enhanced.
Description
Technical field
The utility model relates to the high outlet pipe of a kind of fork truck, is specifically related to a kind of integrated high outlet pipe.
Background technique
When diesel fork lift truck work, air and fuel oil are mixed into after engine combustion, produce the gas push piston movement of High Temperature High Pressure, and after gas energy discharges, these gases just become waste gas and give off outside motor.Wherein the effect of vent systems is exactly by the high temperature high noisy waste gas producing after engine combustion work done, after its sound-deadening and noise-reducing, is discharged in atmosphere and goes, and reduces the noise pollution to environment.At present diesel fork lift truck high-order exhausting system comprises high outlet pipe, silencing apparatus, tail pipe, the waste gas that motor produces enters silencing apparatus after high outlet pipe is guided to certain height reduce noise after again by tailpipe in atmosphere.Its silencing apparatus is generally arranged in the dead astern of fork truck radiator, because the profile of present fork truck is more and smaller and more exquisite, interior layout is also relative more and more compacter, make the gap between silencing apparatus and radiator only have 20mm left and right, seriously increase the exhaust resistance of radiator, thereby the heat dissipation potential of radiator is significantly reduced, finally cause the faults such as motor, transmission device be overheated.Meanwhile, be subject to the volume of limitation silencing apparatus of inner space generally less, it is limited that it reduces noise, and cause diesel fork lift truck exhaust sound still larger, affects working environment.
Model utility content
The utility model, in order to solve the problems of the technologies described above, provides a kind of integrated high outlet pipe, and the high temperature high noisy waste gas that integrated function of exhaust and noise elimination realization is produced motor discharges, and reduces the impact on radiator.
The technical solution of the utility model is: a kind of integrated high outlet pipe, comprise silencing apparatus, the two ends of described silencing apparatus are connected with respectively suction tude and outlet pipe, and the tail end of described suction tude is provided with for fixing support is installed, and between described support and silencing apparatus, is provided with stiffening rib.
Further, for fear of the temperature of silencing apparatus internal high temperature waste gas, on environment and personnel's impact around, the periphery of described silencing apparatus is arranged with the first heat insulation guard shield.
Further, the suction tude periphery between silencing apparatus and support is arranged with the second heat insulation guard shield.
In the utility model, silencing apparatus is selected oval tubular, and its concrete length can be selected according to soundproof effect; The first heat insulation guard shield is identical with the structure of the second heat insulation guard shield, and only boundary dimension difference is all the long cartridge type of porous.
The utility model device is arranged in the balancer weight of fork truck afterbody by support, then suction tude is connected with the relief opening of forklift engine by a segment pipe.The high temperature high noisy waste gas that forklift engine produces enters in silencing apparatus and carries out noise reduction process after suction tude is guided to certain height, then enters in upper atmosphere by outlet pipe, reduces the impact of its NOISE ON ENVIRONMENT and human body.
So the utlity model has following beneficial effect:
1, due to silencing apparatus be the balancer weight of assembling fork tailstock seat, thereby avoid its wind effect that goes out to radiator, significantly reduce the wind resistance that of radiator, significantly reduced the gentle transmission oil temperature of engine water, significantly improved the working life of motor and the each component of transmission system.
2, silencing apparatus is integrated in the balancer weight of high outlet pipe assembling fork tailstock portion, its boundary dimension can not be subject to fork truck body size restrictions and suitably increase, thereby can make the expansion cavity of silencing apparatus and resonant cavity volume increase, significantly strengthen the reduction effect to forklift engine exhaust noise, improve forklift operator personnel travelling comfort.
3, by verification experimental verification, adopt integrated high outlet pipe of the present utility model, after diesel fork lift truck thermal equilibrium, water temperature can reduce by 2 ℃ of left and right, and transmission oil temperature can reduce by 4 ℃ of left and right, and driver in one's ear noise can reduce 1dB left and right.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is that the utility model removes the structural representation after heat insulation guard shield;
Fig. 3 is the heat insulation shroud structure schematic diagram in the utility model;
Fig. 4 is the utility model scheme of installation.
In figure: 1-suction tude, 2-support, 3-stiffening rib, 4-silencing apparatus, the heat insulation guard shield of 5-1 first, the heat insulation guard shield of 5-2 second, 6-outlet pipe.
Embodiment
As shown in Figure 1, 2, 3, a kind of integrated high outlet pipe, comprises silencing apparatus 4, and the two ends of described silencing apparatus 4 are connected with respectively suction tude 1 and outlet pipe 6, the tail end of described suction tude 1 is provided with for fixing support 2 is installed, and between described support 2 and silencing apparatus 4, is provided with stiffening rib 3.Impact for fear of the temperature of silencing apparatus internal high temperature waste gas on environment, reduce the impact on silencing apparatus such as dust in environment simultaneously, the periphery of described silencing apparatus 4 is arranged with the first heat insulation guard shield 5-1, and the suction tude periphery between silencing apparatus 4 and support 2 is arranged with the second heat insulation guard shield 5-2.
This device is arranged in the balancer weight of fork truck afterbody by support 2, the high temperature high noisy waste gas that forklift engine produces enters and in silencing apparatus 4, carries out noise reduction process after suction tude 1 is guided to certain height, then enter in upper atmosphere by outlet pipe 6, reduce the impact of its NOISE ON ENVIRONMENT and human body.
As shown in Figure 4, this integrated high comb is fixed in fork truck afterbody balancer weight 7 by support 2, engine exhaust port is connected with the suction tude 1 of this integrated high outlet pipe by a segment pipe, and this connecting tube trend mainly changes according to the relief opening position of motor.High temperature high noisy waste gas enters in silencing apparatus 4 and carries out noise reduction process, then enters in upper atmosphere by outlet pipe 6, reduces the impact of its NOISE ON ENVIRONMENT and human body.
Above embodiment is not limited only to protection domain of the present utility model, all modify based on basic thought of the present utility model or change all belong to protection domain of the present utility model.
