A strengthening pipe sleeves the corrugated pipe, two ports of the strengthening pipe are respectively buckled on the adapter pipe and the regulating pipe, and a shake absorption device is connected between the adapter pipe and the regulating pipe. The regulated type exhaust pipe assembly is reasonable in structure, torsion connection of a whole exhaust pipe can be achieved through the tail pipe and the regulating pipe which are adjustable in angle, segmented installation can be performed to meet the requirement of the installing position, and the installation and regulation time can be shortened. Tail gas entering the corrugated pipe provides resonance buffering through the elasticity performance, the influence of engine shake on the exhaust pipe is reduced through a shake absorption plate spring, noise produced by an engine during running is reduced, the firmness of the exhaust pipe under the severe driving condition is ensured, a structure is stable and reasonable, and the material cost is saved.
Description
Technical field
The present invention relates to fork truck accessory technical field, particularly adjustment type outlet pipe assembly.
Background technique
Fork truck refer to member pallet cargo load and unload, the various wheeled carrying vehicle of stacking and short distance transportation, weight transport operation.Being widely used in station, harbour, airport, factory, warehouse Deng Ge sector of the national economy, is the high-efficiency appliance of mechanized handling, stacking and short distance transportation.Along with social development, the Environmental Conditions of fork truck is also day by day complicated, in order to adapt to the diversity demand of fork truck function, to fork truck Design and manufacture is also corresponding, has produced higher requirement.
Fork truck is divided into diesel fork lift truck, electri forklift and warehousing forklift, and common diesel fork lift truck has fuel oil or natural gas engine to drive, and its front fork drives by hydraulic system, so in fork truck, is provided with a lot of pipelines and carries out power transmission.And fork truck often need to operation under the narrow and small complex environment of passage, so the layout of its structure of fork truck requires flexibly compactly, and the mounted inside space of fork truck is therefore also very limited.Cause existing fork truck outlet pipe when installing and using, to have dismounting inconvenience, outlet pipe self noise is larger, under complex environment, because the resonance of motor produces, get loose and the problem such as structural strength deficiency, be therefore necessary to make improvements design and install and use performance to improve it.
Summary of the invention
The object of the invention is to defect and deficiency for prior art, a kind of rational in infrastructure, easy accessibility, adjustment type outlet pipe assembly that reliable and stable noise is little are provided.
For achieving the above object, the present invention is by the following technical solutions:
Adjustment type outlet pipe assembly of the present invention, comprise transfer tube and tail pipe, described transfer tube 1 front end is provided with adapter flange 11, adapter flange 11 is provided with conversion adapter 12, transfer tube rear end is connected with the bellows of noise reduction, bellows rear end is connected with the adjutage that can turn to, and adjutage rear end is connected with tail pipe; On described bellows, be arranged with reinforcing pipe, the two-port of reinforcing pipe is detained respectively and is located on transfer tube and adjutage, and is connected with vibration absorber between transfer tube and adjutage.
Further, described vibration absorber comprises arc weakening leaf spring, and the two ends of weakening leaf spring are connected respectively with adjutage with transfer tube by larynx hoop.
Further, described adjutage front end sleeve is located on the rear end of bellows, and adjutage is fixedly connected with bellows by larynx hoop.
Further, described tail pipe front end sleeve is located on the rear end of adjutage, and tail pipe is fixedly connected with adjutage by larynx hoop
Further, described transfer tube front end is provided with adapter flange, and adapter flange is provided with conversion adapter.
Beneficial effect of the present invention is: the present invention is rational in infrastructure, tail pipe and the adjutage by angle adjustable make outlet pipe whole realize reversing is connected, sectional installs to meet the requirement of mounting point, reduces the installation adjustment time; Tail gas provides resonance buffering by its stretchability after entering bellows, by weakening leaf spring, reducing engine vibration affects outlet pipe, reduces the noise that motor operation produces, and guarantees the fastness of outlet pipe under severe driving conditions, structural stability is reasonable, has saved cost of material.
Accompanying drawing explanation
Fig. 1 is whole interior structural representation of the present invention.
In figure:
1, transfer tube; 11, adapter flange; 12, conversion adapter; 2, tail pipe;
3, bellows; 4, adjutage; 5, reinforcing pipe; 6, weakening leaf spring;
7, larynx hoop.
Embodiment
Below in conjunction with accompanying drawing, the present invention is further illustrated.
Adjustment type outlet pipe assembly of the present invention, comprise transfer tube 1 and tail pipe 2, described transfer tube 1 rear end is connected with the bellows 3 of noise reduction, bellows 3 rear ends are connected with the adjutage 4 that can turn to, adjutage 4 rear ends are connected with tail pipe 2, the outlet pipe of multistage combination is by adjusting the connection angle between transfer tube 1 and adjutage 4, tail pipe 2, and then meets the outlet pipe segmentation quick mounting of the interior small space of fork truck; On described bellows 3, be arranged with reinforcing pipe 5, the two-port of reinforcing pipe 5 is detained respectively and is located on transfer tube 1 and adjutage 4, tail gas enters bellows 3 via transfer tube 1, tail gas is cushioned and is eliminated the impact of tail gas in bellows 3 by himself extensibility, and bellows 3 can absorb the vibrations that a part of motor produces; Because bellows 3 is flexible structure, and then the connection of supporting between transfer tube 1 and adjutage 4 by reinforcing pipe 5, between transfer tube 1 and adjutage 4, be connected with vibration absorber, the vibrations that motor produces are delivered on outlet pipe by transfer tube 1, when transfer tube 1 transmits to adjutage 4, by connecting the vibration absorber at two ends, eliminate and weaken.
Above-mentioned vibration absorber comprises arc weakening leaf spring 6, the two ends of weakening leaf spring 6 are connected respectively with adjutage 4 with transfer tube 1 by larynx hoop 7, the two ends of weakening leaf spring 6 are attached on transfer tube 1 and adjutage 4, by larynx hoop 7, connect fixing, and the relative position of the two ends of weakening leaf spring 6 between transfer tube 1 and adjutage 4 is adjustable, and then adjust weakening intensity by changing the curvature of weakening leaf spring 6.
