Abstract
For an outlet pipe for fork truck, comprise a straight tube, one end of described straight tube is stand in channel pipe, and the other end is for going out tunnel tube; Described stand in channel pipe and going out for intervalve between tunnel tube, the diameter of described stand in channel pipe is identical with the diameter going out tunnel tube, and the diameter of described intervalve had both been less than stand in channel pipe, and diameter is less than again the diameter of tunnel tube; The outlet end of described stand in channel pipe is communicated with the entrance point going out tunnel tube and is provided with bypass tube; The inner circle sectional area of bypass tube is equal with the inner circle sectional area of intervalve, and the inner circle sectional area of bypass tube is 1/2 of stand in channel pipe inner circle sectional area, and the length of bypass tube and the length difference of intervalve are the scope of L, L is 50mm-100mm.
Description
Technical field
The utility model belongs to fork truck technical field, is specifically related to a kind of outlet pipe for fork truck.
Background technique
At present, along with user improves constantly the requirement of forklift operator comfort level, the noise problem of fork truck has become an industry difficult problem, especially the noise of vent systems.The vent systems of fork truck is primarily of outlet pipe and silencing apparatus composition: (1), due to the restriction of car load arrangement space, causes muffler volume limited, and acoustical absorptivity is not enough, is difficult to the soundproof effect reaching expectation; (2) the current single steel-pipe construction of the many employings of Domestic Forklift Industry outlet pipe, its structure function is single, only plays air-flow leading role, does not possess noise elimination function.
Model utility content
For solving the large problem of existing forklift truck exhaust system noise, the utility model devises a kind of outlet pipe for fork truck with noise elimination function.
For an outlet pipe for fork truck, comprise a straight tube, one end of described straight tube is stand in channel pipe 1, and the other end is for going out tunnel tube 4; Described stand in channel pipe 1 and going out for intervalve 3 between tunnel tube 4, the diameter of described stand in channel pipe 1 is identical with the diameter going out tunnel tube 4, and the diameter of described intervalve 3 had both been less than the diameter of stand in channel pipe 1, is less than again the diameter of tunnel tube 4;
The outlet end of described stand in channel pipe 1 is communicated with the entrance point going out tunnel tube 4 and is provided with bypass tube 2; The inner circle sectional area of bypass tube 2 is equal with the inner circle sectional area of intervalve 3, and the inner circle sectional area of bypass tube 2 is 1/2 of stand in channel pipe 1 inner circle sectional area, and the length of bypass tube 2 and the length difference of intervalve 3 are the scope of L, L is 50mm-100mm.
Described stand in channel pipe 1, bypass tube 2, intervalve 3 are metal with the material going out tunnel tube 4, and are and are welded to connect.
The entrance point of described stand in channel pipe 1 is communicated with front exhaust pipe assembly 10 by the first clip 9; Described go out the outlet end of tunnel tube 4 be communicated with connecting tube 6 by the second clip 5; Described connecting tube 6 is bend pipe, and its another port is connected with silencing apparatus 8 by the 3rd clip 7.
Advantageous Effects of the present utility model:
(1) the utility model structure is simple, safety easy to use, and is easy to manufacture, be applicable to batch production;
(2) the utility model install on fork truck convenient, and with install not there is noise elimination function outlet pipe vent systems compared with, forklift truck exhaust system of the present utility model is installed and can reduces noise about 5dB;
(3) the length difference L of bypass tube of the present utility model and center-aisle pipe is 1/2 of noise wavelength, thus make phase 1/2 wavelength and interfering when going out tunnel tube and converging of the noise in subchannel pipe and center-aisle pipe, reach the object of noise elimination, both air-flow leading role had been played, the reduction of noise can be realized again, and do not produce any pollution;
(4) the utility model has noise elimination function, thus can replace silencing apparatus, about can reducing fork truck cost 150 yuan/platform.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is Fig. 1 is generalized section.
Fig. 3 is the utility model mounting structure schematic diagram.
Sequence number in upper figure: stand in channel pipe 1, bypass tube 2, intervalve 3, go out tunnel tube 4, second clip 5, connecting tube 6, the 3rd clip 7, silencing apparatus 8, first clip 9, front exhaust pipe assembly 10.
Embodiment
See Fig. 1, Fig. 2, a kind of outlet pipe for fork truck, comprises a straight tube, and one end of described straight tube is stand in channel pipe 1, and the other end is for going out tunnel tube 4; Described stand in channel pipe 1 and going out for intervalve 3 between tunnel tube 4, the diameter of described stand in channel pipe 1 is identical with the diameter going out tunnel tube 4, and the diameter of described intervalve 3 had both been less than the diameter of stand in channel pipe 1, is less than again the diameter of tunnel tube 4.
The outlet end of described stand in channel pipe 1 is communicated with the entrance point going out tunnel tube 4 and is provided with bypass tube 2; The inner circle sectional area of bypass tube 2 is equal with the inner circle sectional area of intervalve 3, and the inner circle sectional area of bypass tube 2 is 1/2 of stand in channel pipe 1 inner circle sectional area, and the length of bypass tube 2 and the length difference of intervalve 3 are the scope of L, L is 50mm-100mm.
Described stand in channel pipe 1, bypass tube 2, intervalve 3 are metal with the material going out tunnel tube 4, and are and are welded to connect.
See Fig. 3, the entrance point of described stand in channel pipe 1 is communicated with front exhaust pipe assembly 10 by the first clip 9; Described go out the outlet end of tunnel tube 4 be communicated with connecting tube 6 by the second clip 5; Described connecting tube 6 is bend pipe, and its another port is connected with silencing apparatus 8 by the 3rd clip 7.
