Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of engineering machinery, and more particularly, to a high exhaust pipe. BACKGROUND

[0002] Internal combustion forklifts usually adopt mid or high exhaust systems to adapt to different working environments. In the application scenario with more dust, the high exhaust system is the first choice, aiming to effectively avoid the problem of dust raising.

[0004] However, due to the slight error in the manufacturing process, the air inlet pipe of the high exhaust pipe and the exhaust tail pipe of the muffler often appear assembly tension phenomenon, not only increasing the installation difficulty, but also in the vibration environment, the change of internal stress is easy to cause the air inlet pipe to break, affecting the overall performance and service life.

[0018] Various exemplary embodiments of the present application will now be described in detail with reference to the accompanying drawings. Note that the relative arrangement, numerical expressions, and numerical values of components and steps set forth in these embodiments are not limiting to the scope of the present application unless otherwise specifically stated.

[0019] The following description of at least one exemplary embodiment is merely exemplary in nature and is in no way intended to limit the application or its application or uses.

[0020] Techniques, methods, and apparatus known to those of ordinary skill in the relevant art can not be discussed in detail herein. However, where appropriate, the techniques, methods, and apparatus should be considered as part of the description of the present application.

[0021] In all of the examples shown and discussed herein, any specific values should be interpreted as merely exemplary, and not as a limitation. Thus, other examples of the exemplary embodiments can have different values.

[0022] The present application provides a high exhaust pipe, which is provided with a deformation pipe section in the middle of the intake pipe, significantly reducing the installation difficulty and improving the assembly flexibility, and reducing the risk of intake pipe breakage in the vibration environment.

[0023] As shown in Figure 1 and 2 The high exhaust pipe provided in the present application includes a main body 1 and an intake pipe connected to the lower end of the main body 1, the intake pipe including a first fixed pipe section 3 located in the lower part and a deformation pipe section 2 between the first fixed pipe section 3 and the lower end of the main body 1. The deformation pipe section can be adaptively deformed as needed during installation to facilitate installation.

[0024] Preferably, a second fixed pipe section 8 is further provided between the deformation pipe section 2 and the lower end of the main body 1. The second fixed pipe section 8 is an inclined pipe section, so that the main body 1 and the lower end of the intake pipe have a certain lateral distance, so that the lower end of the intake pipe is longitudinally aligned with the exhaust tail pipe of the muffler, while meeting the positioning and installation of the high exhaust pipe on the vehicle and the good connection of the intake pipe and the exhaust tail pipe of the muffler.

[0025] As an embodiment, the deformation pipe section 2 is a corrugated pipe, which can realize expansion and deformation, and can meet the requirements of lengthening the intake pipe during installation and shortening the intake pipe after installation.

[0026] Preferably, the corrugated pipe is a metal woven corrugated pipe, which is carefully woven by high-temperature-resistant metal wires, and has good high-temperature resistance and a certain deformation range, ensuring stable work in a high-temperature environment.

[0027] As shown in Figure 1 and 2 , the outer side of the main body 1 is wrapped with a heat shield 4, which is fixed on the main body 1 by bolts 6.

[0028] As shown in Figure 1 and 2 , the upper end of the main body 1 is provided with a snow cap 5 to prevent wind and snow from entering the main body 1.

[0029] As shown in Figure 1 and 2 , the lower end of the main body 1 is fixedly connected with a connecting plate 7. As shown in Figure 3 , the connecting plate 7 is fixed on the top surface of the counterweight 11 of the vehicle (for example, a forklift 10). At the same time, the lower end of the intake pipe is connected with the exhaust tail pipe of the muffler.

[0030] During installation, the deformation pipe section can effectively absorb and compensate manufacturing errors by its moderate deformation ability, greatly simplifying the assembly process between the exhaust tail pipe of the muffler, the intake pipe of the high exhaust pipe, and the connecting plate of the high exhaust pipe, ensuring smooth and accurate installation, and significantly improving production efficiency. At the same time, the vibration stress is effectively relieved by the deformation pipe section, greatly prolonging the overall service life of the high exhaust pipe, and providing users with a more economical and reliable solution.

[0031] Although some specific embodiments of the present application have been described in detail through examples, those skilled in the art should understand that the above examples are only for illustration, not for limiting the scope of the present application. Those skilled in the art should understand that the above embodiments can be modified without departing from the scope and spirit of the present application. The scope of the present application is defined by the appended claims.
