Description

Technical Field

[0001] The utility model relates to the technical field of mining vehicles, in particular to a supporting device for a post-processing system of a mining vehicle. Background Art

[0002] With the acceleration of urbanization and the continuous enhancement of people's environmental awareness, my country's environmental protection supervision has become increasingly stringent, and the exhaust gas treatment standards for non-road mobile machinery have been gradually improved, extending from the automotive field to sub-sectors such as ships, power generation, and non-road machinery. On December 28, 2020, the Ministry of Ecology and Environment issued the "Technical Requirements for Pollutant Emission Control of Non-road Diesel Mobile Machinery" (HJ 1014-2020), which clearly stipulates that "from December 1, 2022, all non-road mobile machinery below 560kW (including 560kW) produced, imported and sold and the diesel engines installed therein shall comply with the requirements of this standard." This standard applies to non-road machinery such as excavators, tractors, and combine harvesters. The fourth stage standard (hereinafter referred to as "National IV") in the "Emission Limits and Measurement Methods of Exhaust Pollutants from Diesel Engines for Non-road Mobile Machinery (China Phase III and IV)" will be officially implemented.

[0003] The primary challenge posed by the implementation of the "National IV" emission standard is emission reduction, including both basic and post-treatment emission reduction. Basic emission reduction technologies primarily improve engine performance, including optimizing the phase difference and sealing of the intake and exhaust valves, optimizing carburetor performance, and optimizing ECU execution performance. To meet the "National IV" emission standard, the engine requires an additional exhaust after-treatment system. Due to the large size of the after-treatment system, the heavy load, long continuous operation time, poor road conditions, and complex working environment of mining vehicles, the vibration generated by the vehicle during operation can easily damage the after-treatment system, thus shortening its service life. Utility Model Content

[0004] In view of the defects in the prior art, the utility model provides a supporting device for a post-processing system of a mining vehicle, which is used to solve the problem of fixed installation of the post-processing system.

[0005] The utility model provides a support device for a post-processing system of a mining vehicle, comprising a bracket, wherein the brackets are symmetrically arranged, and the post-processing system is arranged between two of the brackets, and the brackets include:

[0006] A bottom plate, which is vertically arranged and used to be connected to the frame;

[0007] A longitudinal beam connected to the bottom plate, wherein the longitudinal beam is connected to a post-processing system;

[0008] The first reinforcing plate has one end connected to the bottom plate and the other end arranged along the longitudinal beam, and the bottom of the first reinforcing plate is connected to the longitudinal beam.

[0009] It can be seen from the above technical solution that the utility model provides a support device for the post-processing system of a mining vehicle. By symmetrically arranging two brackets, the post-processing system is arranged between the two brackets, and the post-processing system and the vehicle frame can be fixed, thereby meeting the support requirements of the post-processing system and ensuring the reliability of the structure.

[0010] Optionally, the longitudinal beam includes an integrally formed horizontal section and an inclined section, and the other end of the first reinforcing plate extends to the horizontal section. To adjust the height of the aftertreatment system relative to the vehicle frame after installation, the integrally formed horizontal section and inclined section ensure that the aftertreatment system is positioned at an appropriate height after installation, avoiding interference with the layout of other structures.

[0011] Optionally, a second reinforcement plate is provided on the inner side of the horizontal section, positioned at the junction of the horizontal section and the inclined section. The two ends of the second reinforcement plate are bent in the same direction and arranged perpendicularly to the longitudinal beam. To strengthen the connection between the horizontal and inclined sections and prevent vibration of the after-treatment system during vehicle operation, which could cause the horizontal and inclined sections to separate and affect the reliability of the support device, the second reinforcement plate is used to provide structural reinforcement, thereby improving the installation reliability of the after-treatment system.

[0012] Optionally, a third reinforcing plate is provided on the bottom surface of the base plate, and the third reinforcing plate is provided in contact with the bottom surface of the inclined section. The third reinforcing plate is used to support the bottom of the inclined section, strengthen the connection strength between the base plate and the longitudinal beam, and prevent the longitudinal beam from being separated from the base plate.

[0013] Optionally, a plurality of fourth reinforcing plates are arranged at intervals on the inner side of the horizontal section, and the fourth reinforcing plates are arranged perpendicular to the horizontal section.

[0014] Optionally, the bottom plate and the longitudinal beam are welded together, and a first plug welding hole is provided on the bottom plate, and the first plug welding hole facilitates welding between the bottom plate and the longitudinal beam.

[0015] Optionally, the first reinforcing plate includes an integrally formed welding section, a bent section, and a reinforcing section, the welding section being welded to the bottom plate, and the bottom surface of the reinforcing section being welded to the longitudinal beam. The bent section provides a gap between the first reinforcing plate and the bottom plate, thereby increasing the connection strength between the longitudinal beam and the bottom plate and ensuring structural reliability.

[0016] Optionally, a second plug welding hole is opened on the welding section, and the second plug welding hole is convenient for strengthening the welding between the first reinforcing plate and the bottom plate.

[0017] By adopting the above technical solution, this application has the following technical effects:
