Abstract
The utility model relates to an engine exhaust pipe for an exterior of a heavy-type forklift body. A protective pipe is sleeved outside an exhaust pipe body, heat dissipation holes are evenly distributed in the protective sleeve, the upper end of the protective pipe is fixedly communicated with the exhaust pipe body through an upper circular-ring plate, and the lower end of the protective pipe is an impending end. A guiding short pipe is sleeved on the exhaust pipe body corresponding to the lower end of the protective pipe, the lower end of the guiding short pipe is fixedly connected with the exhaust pipe body through a lower circular-ring plate, a ring-shaped space is formed between the upper end of the guiding short pipe and the exhaust pipe body, and the lower end of the protective pipe is arranged in the guiding short pipe. The engine exhaust pipe enables the lower end of the protective pipe to be suspended in the air and to freely stretch in the guiding short pipe through structural improvement, the deformation condition of the protective pipe is effectively improved, and the protective pipe can effectively exert a function of safe protection. The engine exhaust pipe is simple in structure, good in manufacturability and easy to produce and manufacture.
Description
Technical field
The utility model belongs to heavy fork truck technical field, is specifically related to the engine exhaust pipe of heavy fork truck.
Background technique
Vent systems is as important and indispensable system in the vehicle power parts, its main function be exhaust emissions with motor in atmosphere, can reduce the vehicle exhaust noise effectively in addition, improve the human engineering travelling comfort.While to installation and the high temperature protection of gas exhaust piping, has all proposed strict requirement and restriction according to relevant criterion in vent systems.The gas exhaust piping of car body inside generally adopts thermal-protective material to wrap up now, and the outlet pipe pipeline in the car body outside generally adopts the method that increases heat-insulating shield to carry out safety protection.Because the exhaust temperature of engine emission is higher, the position of the heat-insulating shield on the outlet pipe in the car body outside is fixed simultaneously, in the effect of effect that is subjected to expanding with heat and contract with cold for a long time, the boundary dimension of himself is in continuous variation, and cause its dimensional changes can't obtain timely discharging owing to be subjected to the restriction of structure, cause it to produce distortion, even when serious, can damage whole gas exhaust piping, influence proper functioning and its function of safety protection of vehicle, produce potential safety hazard.
Summary of the invention
For the problem that produces in the long-time use of the heat-insulating shield on the outlet pipe that solves the car body outside, the utility model provides a kind of engine exhaust pipe that is used for heavy fork truck car body outside that improves structure.
The engine exhaust pipe that is used for heavy fork truck car body outside comprises outlet pipe, and the outlet pipe outer cover is provided with protecting tube, the uniform radiation hole that offers on the described protecting tube; The upper end of protecting tube fixedly is being communicated with outlet pipe by upper ring plate, and the lower end of protecting tube is free end; Be arranged with the guiding short tube on the outlet pipe corresponding with the protecting tube lower end, the lower end of described guiding short tube by following Circular Plate fixedly connected outlet pipe, form the space of ring-type between the upper end of guiding short tube and the outlet pipe, the lower end of protecting tube is positioned at the guiding short tube.
Distance under the protecting tube between the fixed end of end distance guiding short tube is 40～50 ㎜.
Useful technique effect of the present utility model embodies in the following areas:
1. the utility model makes the lower end of protecting tube unsettled by architecture advances, and can freely stretch in the guiding short tube, has effectively improved the distortion situation of protecting tube, makes its effectively performance function of safety protection;
2. the utility model is simple in structure, and good manufacturability is easy to manufacture.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the partial enlarged drawing of Fig. 1.
Sequence number among the last figure: outlet pipe 1, upper ring plate 2, protecting tube 3, guiding short tube 4, following Circular Plate 5.
Embodiment
Following structure accompanying drawing, the utility model is further described by embodiment.
Referring to Fig. 1, the engine exhaust pipe that is used for heavy fork truck car body outside comprises outlet pipe 1, and outlet pipe 1 outer cover is equipped with protecting tube 3, the uniform radiation hole that offers on the protecting tube 3, the upper end of protecting tube 3 fixedly is being communicated with outlet pipe 1 by upper ring plate 2, and the lower end of protecting tube 3 is free end.Referring to Fig. 2, be set with guiding short tube 4 on the outlet pipe 1 corresponding with protecting tube 3 lower ends, the length of guiding short tube is 45 ㎜.The lower end of guiding short tube 4 by following Circular Plate 5 fixedly connected outlet pipe 1, form the space of ring-type between the upper end of guiding short tube 4 and the outlet pipe 1, the lower end of protecting tube 3 is positioned at guiding short tube 4, and the distance under the protecting tube between the fixed end of end distance guiding short tube is 45 ㎜.When expanding with heat and contract with cold effect, can freely stretch vertically in the lower end of protecting tube 3; 4 effects of guiding short tube are to limit the motion of the direction of protecting tube 3.
Claims (2)
1. the engine exhaust pipe that is used for heavy fork truck car body outside, comprise outlet pipe, the outlet pipe outer cover is provided with protecting tube, the uniform radiation hole that offers on the described protecting tube, it is characterized in that: the upper end of described protecting tube fixedly is being communicated with outlet pipe by upper ring plate, and the lower end of protecting tube is free end; Be arranged with the guiding short tube on the outlet pipe corresponding with the protecting tube lower end, the lower end of described guiding short tube by following Circular Plate fixedly connected outlet pipe, form the space of ring-type between the upper end of guiding short tube and the outlet pipe, the lower end of protecting tube is positioned at the guiding short tube.
2. the engine exhaust pipe for heavy fork truck car body outside according to claim 1 is characterized in that: the distance under the protecting tube between the fixed end of end distance guiding short tube is 40～50 ㎜.
