[0039] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0040] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0041] As a fulcrum for drivers or maintenance personnel, pedals require sufficient support area to ensure stable support for the human body. This necessitates a large installation space for pedals. Due to the demand for large-capacity fuel tanks in heavy vehicles such as engineering equipment, as well as the assembly requirements of various chassis accessories, the space available for pedal placement on the rear side of the vehicle chassis is limited. Consequently, it is difficult to install pedals on the rear side of the chassis, making it difficult to form a fulcrum structure for personnel to step on in the rear side of vehicles such as engineering equipment. This causes inconvenience for the maintenance of accessories such as the rear side frame, hydraulic station, and wiring harness.

[0042] To address the technical problem of the difficulty in placing pedals on the middle and rear sides of the vehicle body, which causes inconvenience to the maintenance of the equipment, this application provides an aftertreatment system and engineering equipment. By setting a pedal structure at the aftertreatment point, the aftertreatment system can serve as a fulcrum for maintenance personnel to step on, thereby facilitating vehicle maintenance.

[0043] It should be noted that the post-processing system described in this application is used in, but not limited to, cranes, and can also be applied to other engineering equipment such as tractors and excavators. For ease of explanation, this application only uses the application of the post-processing system to crane engineering equipment as an example. The principle of the post-processing system applied to other engineering equipment is essentially the same as that applied to cranes, and will not be described in detail here.

[0044] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0045] To better understand this application, the following is combined with... Figures 1 to 5 The technical solution of this application is described in detail below:

[0046] This application provides a post-processing system, such as... Figure 1 As shown, the aftertreatment system includes an aftertreatment device 10, which can be connected to the turbocharger outlet or exhaust manifold. Through chemical reactions and physical filtration, it converts toxic and harmful substances in engine exhaust into harmless components, ensuring the vehicle meets environmental regulations. Its core components include, but are not limited to, a urea tank, a urea pump, urea injectors, an SCR catalytic converter, and a diesel particulate filter. The urea tank stores a 32.5% urea aqueous solution; the urea pump pressurizes and delivers urea; the urea injectors spray urea into the exhaust pipe; the SCR catalytic converter catalytically reduces urea; and the diesel particulate filter filters particulate matter, thus treating the exhaust gas to meet emission standards.

[0047] In this embodiment, as Figure 1 As shown, the aftertreatment device 10 includes an intake component 11 and an exhaust component 12. The exhaust component 12 purifies the pollutants that have been generated and is equipped with an SCR catalyst (Selective Catalytic Reduction Catalyst), a urea injection system, etc., to purify the exhaust gas. The intake component 11 reintroduces some of the exhaust gas into the cylinder to reduce the combustion temperature of the fuel and reduce the amount of nitrogen oxides generated.

[0048] like Figure 1 and Figure 2 As shown, the post-processing system provided in this application embodiment also includes a support component 20 and a pedal assembly 30. One end of the support component 20 is fixed to the post-processing device 10, and the other end of the support component 20 extends away from the post-processing device 10. The pedal assembly 30 is installed at the end of the support component 20 away from the post-processing device 10.

[0049] Specifically, by providing a support assembly 20 and a pedal assembly 30, the aftertreatment device 10 can not only perform the function of exhaust gas purification, but also serve as a foot pedal structure for personnel to step on. Specifically, the aftertreatment device 10 is mounted on the chassis and supported by the chassis. The support assembly 20 allows the pedal assembly 30 to be installed on the aftertreatment device 10 and provides support for the pedal assembly 30, so that personnel can step on the aftertreatment device 10 through the pedal assembly 30, thereby facilitating maintenance work near the vehicle body where the aftertreatment device 10 is located.

[0050] Understandably, the post-processing device 10 is typically installed in the middle and rear sections of the engineering equipment to provide footholds and facilitate maintenance of these sections. Of course, the post-processing device 10 can also be installed in any location other than the middle and rear sections of the engineering equipment. For example, it can be installed in the front, mid-front, and rear sections of the engineering equipment. When installed in these locations, it provides footholds and facilitates maintenance of these sections.

[0051] Understandably, the support assembly 20 can be connected to the side of the pedal assembly 30 to provide support for the pedal assembly 30, or connected to the bottom surface of the pedal assembly 30 to provide support for the pedal assembly 30.

[0052] In some embodiments, such as Figure 2 As shown, the support assembly 20 includes a top support frame 21, which is fixed to the top of the post-processing device 10, and the pedal assembly 30 includes a foot pedal 31, which is fixed to the top support frame 21.

[0053] Specifically, the top of the aftertreatment device 10 is the part of the aftertreatment device 10 located near the roof of the vehicle. The pedal assembly 30 has a pedal section 31 that forms a pedal structure for people to step on. The pedal section 31 can be supported by the top support frame 21 and is arranged on one side of the top of the aftertreatment device 10. This makes full use of the top space of the aftertreatment device 10, facilitates the installation and layout of the pedal assembly 30, and ensures that the force on the top support frame 21 is in the extension direction of the top support frame 21, thus avoiding deformation of the top support frame 21.

[0054] To enhance the strength of the foot pedal 31, in some embodiments, such as Figure 5As shown, the pedal assembly 30 also includes a transverse reinforcing beam 32 and a longitudinal reinforcing beam 33, which are arranged crosswise and fixed to the side of the foot pedal 31 near the top support frame 21. Specifically, by being provided on the foot pedal 31, the transverse reinforcing beam 32 and the longitudinal reinforcing beam 33 can effectively strengthen the foot pedal 31 and prevent deformation of the foot pedal 31.

[0055] In this embodiment, when the foot pedal 31 is connected to the top support frame 21, the transverse reinforcing beam 32 and the longitudinal reinforcing beam 33 abut against the top support frame 21 to prevent the foot pedal 31 from being suspended where it is not connected to the top support frame 21, thereby preventing the foot pedal 31 from deforming.

[0056] Understandably, the top support frame 21 can be any frame structure capable of providing support for the footrest 31.

[0057] In some embodiments, such as Figure 2 and Figure 3 As shown, the top support frame 21 includes a support member 211 and a support plate 212. The support member 211 is fixed to the top of the post-processing device 10, and the support plate 212 is fixed to the support member 211. The foot pedal 31 is fixed to the support plate 212. Specifically, the support member 211 can fix the top support frame 21 to the post-processing device 10. It will serve as the main load-bearing component of the top support frame 21, providing support for the support plate 212. The support plate 212 converts the point support of the support member 211 on the foot pedal 31 into surface support, thereby preventing deformation of the foot pedal 31.

[0058] Since the top surface of the post-processing device 10 is an uneven surface, in order to achieve the mounting layout of the support member 211 on the top of the post-processing device 10, in some embodiments, such as Figure 4 As shown, the support member 211 includes a first bracket 2111, a second bracket 2112 and several third brackets 2113. The first bracket 2111 is installed on the air intake member 11 and fixed to the air intake member 11. The second bracket 2112 is fixed to the exhaust member 12. The third brackets 2113 are distributed on the air intake member 11 and the exhaust member 12. The support plate 212 is fixed to the first bracket 2111, the second bracket 2112 and the third brackets 2113. Specifically, since accessories are provided on the top surfaces of both the intake component 11 and the exhaust component 12, the support component 211 is disassembled into a frame structure including a first bracket 2111, a second bracket 2112, and several third brackets 2113. This allows the support component 211 to be distributed on both the intake component 11 and the exhaust component 12. The first bracket 2111, the second bracket 2112, and each of the third brackets 2113 can be adapted to be placed on the top of the intake component 11 and the exhaust component 12 where no accessories are provided, thereby facilitating the placement of the support component 211 on the top of the aftertreatment device 10.

[0059] Understandably, the shape and arrangement of the first support 2111, the second support 2112, and each of the third supports 2113 can be adjusted adaptively according to actual needs. The end face heights of the first support 2111, the second support 2112, and each of the third supports 2113 should be consistent to keep the support plate 212 horizontal.

[0060] In this embodiment, as Figure 4 As shown, the first bracket 2111 and the second bracket 2112 are respectively fixed to the middle parts of the air intake component 11 and the exhaust component 12, and the third brackets 2113 are located on both sides of the first bracket 2111 and the second bracket 2112. The first bracket 2111 and the second bracket 2112 have a "U" shaped structure. The open sides of the first bracket 2111 and the second bracket 2112 are fixed to the top of the air intake component 11 and the exhaust component 12 by bolts. The first bracket 2111 and the second bracket 2112 form a planar support, and the third bracket 2113 is a single-point support. The support plate 212 is fixed to the ends of the first bracket 2111, the second bracket 2112 and the third bracket 2113 by bolts.

[0061] In some embodiments, such as Figure 2 As shown, the support member 211 extends away from the post-processing device 10 to form a first heat dissipation space 10a between the foot pedal 31 and the post-processing device 10. Specifically, the support member 211 extends away from the post-processing device 10 so that the foot pedal 31 can be moved away from the post-processing device 10, thereby reserving a first heat dissipation space 10a below for the post-processing device 10 to dissipate heat, and avoiding the foot pedal 31 affecting the heat dissipation of the post-processing device 10.

[0062] In some embodiments, such as Figure 3 As shown, the support plate 212 includes a first plate body 2121 and a second plate body 2122. The first plate body 2121 is fixed to the first bracket 2111, and the second plate body 2122 is fixed to the second bracket 2112 and each of the third brackets 2113. Specifically, by dividing the support plate 212 into the first plate body 2121 and the second plate body 2122, the arrangement of the support plate 212 becomes more flexible, and it can be adaptively adjusted according to the arrangement of the first bracket 2111, the second bracket 2112 and each of the third brackets 2113, thus facilitating the installation of the support plate 212.

[0063] In this embodiment, the area of ​​the first plate 2121 is larger than the area of ​​the second plate 2122. Since the top of the air intake 11 needs to be arranged with accessories such as wiring harnesses, the large area of ​​the first plate 2121 can provide protection for the accessories.

[0064] Understandably, the area of ​​the first plate 2121 can also be configured to be less than or equal to the area of ​​the second plate 2122, as long as it can support the foot pedal 31.

[0065] In this embodiment, as Figure 3 As shown, the first plate 2121 and the second plate 2122 are each provided with four threaded holes, and the stepping part 31 is connected to the four threaded holes of the first plate 2121 and the second plate 2122 by bolts.

[0066] In some embodiments, such as Figure 5 As shown, the pedal assembly 30 also includes two opposing fixed crossbeams 34. The two fixed crossbeams 34 are fixed to the side of the foot pedal 31 near the top support frame 21 and are fixedly connected to the top support frame 21. Specifically, the fixed crossbeams 34, through their connection with the top support frame 21, fix the foot pedal 31 to the top support frame 21. The strength of the fixed crossbeams 34 is greater than the strength of the foot pedal 31. Since the connection between the pedal assembly 30 and the top support frame 21 is subjected to greater force, the connection between the fixed crossbeams 34 and the top support frame 21 can effectively prevent deformation of the connection between the pedal assembly 30 and the top support frame 21.

[0067] In this embodiment, one side of the fixed crossbeam 34 is fixed to the bottom surface of the foot pedal 31, and the other side of the fixed crossbeam 34 is away from the foot pedal 31, so that while being fixed to the foot pedal 31, a certain distance can be maintained between them. The side of the fixed crossbeam 34 away from the foot pedal 31 is fixed to the threaded hole on the first plate 2121 and the second plate 2122 by bolts.

[0068] In some embodiments, such as Figure 2 , Figure 3 and Figure 4 As shown, the support assembly 20 also includes two sets of side support frames 221, which are fixed to both sides of the post-processing device 10. The pedal assembly 30 also includes lateral support portions 35 connected to both sides of the pedal portion 31. The lateral support portions 35 are arranged at an angle to the pedal portion 31 and are respectively connected to the two sets of side support frames 221. Specifically, in addition to being supported by the top support frame 21, the pedal assembly 30 can also be supported by the connection between the side support frames 221 and the lateral support portions 35, thereby assisting in the support of the pedal assembly 30. In addition to assisting the top support frame 21 in the vertical direction, the side support frames 221 can also provide support for the pedal assembly 30 in the horizontal direction, thereby preventing deformation of the top support frame 21.

[0069] In some embodiments, to strengthen the connection between the lateral support 35 and the foot pedal 31, such as... Figure 5As shown, the pedal assembly 30 also includes a reinforcing rib 36, the middle portion of which is connected to the foot pedal 31, and both ends of which are connected to the lateral support portion 35. Specifically, by connecting the foot pedal 31 and the lateral support portion 35, the reinforcing rib 36 can strengthen the connection between the lateral support portion 35 and the foot pedal 31, thereby preventing deformation of the lateral support portion 35.

[0070] Understandably, the side support frame 221 can be threaded through the side support part 35, or connected to the side support part 35 by means of snap-fitting, etc.

[0071] In some embodiments, such as Figure 2 , Figure 3 and Figure 4 As shown, the side support frame 221 includes a fourth bracket 2211 arranged opposite to each other, and the lateral support part 35 is fixed to the fourth bracket 2211. Specifically, both sides of the side support frame 221 can be connected to the lateral support part 35 through two oppositely arranged fourth brackets 2211, so as to limit and support the lateral support part 35.

[0072] In this embodiment, the lateral support 35 is fixed to the end of the lateral support frame 221 by bolts.

[0073] Understandably, the side support frame 221 can also be any frame structure that can connect to the side support part 35.

[0074] In some embodiments, such as Figure 2 As shown, the side support frame 221 extends away from the post-processing device 10, so that a second heat dissipation space 10b is formed between the side support portion 35 and the post-processing device 10. Specifically, the side support frame 221 extends away from the post-processing device 10, so that the side support portion 35 can be moved away from the post-processing device 10, thereby reserving a first heat dissipation space 10a between the side support portion 35 and the post-processing device 10 for heat dissipation of the post-processing device 10, and avoiding the side support portion 35 affecting the heat dissipation of the post-processing device 10.

[0075] In some embodiments, such as Figure 5 As shown, the pedal assembly 30 is provided with a plurality of spaced-apart heat dissipation holes 37. Specifically, the first heat dissipation space 10a, the second heat dissipation space 10b, and the heat dissipation holes 37 can all provide heat dissipation for the post-processing device 10. With the cooperation of the first heat dissipation space 10a, the second heat dissipation space 10b, and the heat dissipation holes 37, the arrangement of the pedal assembly 30 can be effectively prevented from affecting the heat dissipation of the post-processing device 10, and the wire harness ablation caused by heat accumulation can be avoided.

[0076] In this embodiment, the shape of the heat dissipation hole 37 can be any shape, such as circular, square or irregular, and this embodiment does not impose any specific limitation.

[0077] In some embodiments, such as Figure 1 , Figure 2 and Figure 4 As shown, the post-processing system also includes a sensing module 40, which is integrated into the post-processing device 10. Specifically, by integrating the sensing module 40, it can be placed inside the pedal assembly 30, thereby being protected by the pedal assembly 30 and effectively preventing damage to the sensing module 40.

[0078] In this embodiment, the sensing module 40 includes sensing components such as a differential pressure sensor, an exhaust temperature sensor, and an integrated wiring harness, which are integrated and arranged in the air intake component 11.

[0079] In this embodiment, the pedal assembly 30, in addition to being stepped on by personnel, can also serve as a protective cover to block foreign objects such as weeds and stones, providing protection for the post-processing device 10, the sensing module 40 and related wiring harnesses, thereby preventing external foreign objects from impacting the post-processing device 10 and related accessories.

[0080] In some embodiments, such as Figure 1 and Figure 2 As shown, the after-processing system also includes a bottom support frame 50, which is connected to the bottom of the after-processing device 10. Specifically, the bottom support frame 50 is fixedly connected to the chassis, enabling the after-processing system to be installed on the chassis. After the bottom support frame 50 is fixed to the chassis, it can provide support for the after-processing device 10.

[0081] In this embodiment, the air intake component 11 and the exhaust component 12 of the post-processing device 10 are respectively provided with an air intake section and an exhaust section. The air intake section and the exhaust section are respectively provided with an air inlet and an exhaust outlet. The air intake section and the exhaust section are rotatably connected to the air intake component 11 and the exhaust component 12 respectively. The post-processing device 10 can form a mirror structure by rotating the air intake section and the exhaust section around the air intake component 11 and the exhaust component 12, and can adjust the angle of the air inlet and the air outlet by rotating the air intake section and the exhaust section to meet the installation requirements of different types of engineering equipment.

[0082] This application embodiment also provides an engineering device, including a chassis and the aforementioned post-processing system, with a foot pedal 31 mounted on the chassis. Specifically, by setting the post-processing system on the chassis, the engineering device forms a foot pedal structure at the location of the post-processing system, allowing personnel to step on it and facilitating the maintenance of the engineering device.

[0083] In this embodiment, the post-processing system of the engineering equipment forms a stepping structure, which not only allows personnel to step on it but also provides protection for the post-processing system, preventing damage from impacts by foreign objects. Furthermore, the angles of the air inlet 11 and exhaust outlet 12 of the post-processing device 10 can be adjusted as needed, thereby enabling the post-processing system of the engineering equipment to be more compatible with the engineering equipment.

[0084] In this embodiment, the engineering equipment may include engineering vehicles, heavy trucks, trailers, excavators, roadheaders, bulldozers, road rollers, and concrete pump trucks, etc.
