The following provides some embodiments of aftertreatment mounting platform, work machine auxiliary system and work machine among the technical scheme of the utility model.
In an embodiment of the first aspect of the present invention a post-processing mounting platform 1 is provided. As shown in fig. 1 and 2, the aftertreatment mounting platform 1 includes a frame assembly 11 and a mounting bracket assembly 12. The frame assembly 11 is used as a main body structure of the post-processing mounting platform 1, mainly provides mounting space for the mounting frame assembly 12 and related devices, and supports the related devices; meanwhile, during assembly, the frame assembly 11 is connected to the vehicle body of the working machine. The frame assembly 11 includes a first frame part 111 and a second frame part 112 arranged in the transverse direction, and the first frame part 111 is connected to the second frame part 112.
The mounting rack assembly 12 includes a post-processor mounting rack 121, a urea tank mounting rack 122, an air filter mounting rack 123, a urea pump mounting rack 124, and an oil-water separator mounting rack 125; wherein the post-processor mounting frame 121 is provided on the first frame part 111, the first frame part 111 alone is used to mount the post-processor 21 due to the large volume of the post-processor 21, to provide sufficient space for the post-processor 21; the urea tank mounting rack 122 and the air filter mounting rack 123 are arranged on the second frame portion 112 and located at the top of the second frame portion 112, and the urea pump mounting rack 124 and the oil-water separator mounting rack 125 are arranged at the bottom of the second frame portion 112, so that the three-dimensional space above and below the second frame portion 112 is fully utilized, and the spatial layout is optimized. Wherein the top of the second frame portion 112 corresponds to the upper portion in the height direction, and the bottom of the second frame portion 112 corresponds to the lower portion in the height direction.
In the assembly, the post-processor 21, the urea tank 22, the air filter 23, the urea pump 24, and the oil-water separator 25 may be mounted on the corresponding mounting brackets, respectively, as shown in fig. 2, and then the above-described device and the post-processing mounting platform 1 may be integrally mounted on the vehicle body of the working machine.
It can be understood that some existing integrated mounting platforms or supporting structures can also achieve integrated mounting of multiple devices, but the structural layout is still unreasonable, the space between multiple devices is small, assembly and post-maintenance operations are inconvenient, and it is difficult to integrate auxiliary devices related to post-processing on one platform, and the individual auxiliary devices also need to be provided with mounting structures on the working machine, so that the pipeline connection between the auxiliary devices is not simplified enough, and the overall assembly efficiency is affected.
The post-treatment installation platform 1 in this embodiment is improved and optimized in structure and spatial layout, and can integrate the post-treatment device 21, the urea tank 22 related to post-treatment, the air filter 23, the urea pump 24, the oil-water separator 25 and other auxiliary devices on the same installation platform to form a modular structure, so that the one-time integral assembly operation can be realized in the assembly process with the vehicle body of the operation machine, and the assembly efficiency can be greatly improved. Meanwhile, the limited space is fully utilized, so that the post-processor 21 and the auxiliary devices are mutually matched in position relation, and the post-processor can be well matched with devices such as an engine of a working machine (such as a land scraper) and the like, the mutual position interference can be reduced, and the pipeline connection and the later maintenance operation can be facilitated.
It should be noted that the work machine described in the present embodiment and the following embodiments includes, but is not limited to, a motor grader.
In a further embodiment of the present invention, as shown in fig. 1 to 3, in the post-treatment mounting platform 1, the urea tank mounting bracket 122 and the air filter mounting bracket 123 are both disposed at the top of the second frame portion 112, and in the longitudinal direction, the urea tank mounting bracket 122 is located in front of the air filter mounting bracket 123, so that after the assembly, the urea tank 22 and the air filter 23 can be kept in a suitable arrangement in the longitudinal direction, which is advantageous for improving the space utilization rate and facilitating the pipeline connection.
In the lateral direction of the second frame part 112, a urea pump mount 124 is provided at one end of the second frame part 112 close to the first frame part 111 to facilitate connection between the urea pump 24 and the urea tank 22; the oil-water separator mounting bracket 125 is provided at an end of the second frame portion 112 remote from the first frame portion 111 so that the oil-water separator 25 is located at a position close to the vehicle body outer side after being integrally assembled to the vehicle body of the working machine, for the convenience of maintenance operation. It can be understood that, during normal use, the oil-water separator 25 needs relatively frequent maintenance operations, and the arrangement manner in this embodiment can greatly improve the convenience of the maintenance operations of the oil-water separator 25.
In a further embodiment of the present invention, as shown in fig. 1 to 3, in the aftertreatment mounting platform 1, the first frame section 111 includes a first main frame 1111 and a first sub-bracket 1115. In the longitudinal direction, the first sub-bracket 1115 is attached to the rear end of the first main frame 1111 to increase the size of the first frame section 111 in the longitudinal direction to fit the shape of the post-processor 21. Wherein, post processor mounting bracket 121 sets up to a plurality ofly, sets up respectively on first frame and first sub-support 1115, and post processor mounting bracket 121 all sets up along horizontal to be connected with aftertreatment ware 21, specifically, at least one post processor mounting bracket 121 among a plurality of post processor mounting brackets 121 locates on first main frame 1111, and remaining post processor mounting bracket 121 locates on first sub-support 1115.
It is understood that most of the conventional post-processors are cylindrical structures or structures close to cylindrical structures, and have relatively large dimensions in the axial direction, and when the post-processor mounting platform 1 is assembled, the axial direction of the post-processor can be arranged along the longitudinal direction of the first frame part 111 to connect and support the post-processor at multiple points in the longitudinal direction through the plurality of post-processor mounting brackets 121.
Further, as shown in fig. 3, the first main frame 1111 includes a plurality of first main longitudinal beams 1112 and a plurality of first main transverse beams 1113, the first sub-bracket 1115 includes a plurality of first sub-longitudinal beams 1116 and at least one first sub-transverse beam 1117, and the post-processor mounting brackets 121 are disposed on the first sub-transverse beam 1117 at the rear end and the first main transverse beam 1113 at the front end in the longitudinal direction. For example, in the example shown in fig. 3, the first main frame 1111 is specifically formed by connecting two first main longitudinal beams 1112 and two first main transverse beams 1113 to form a quadrilateral frame structure, and the first sub-bracket 1115 is formed by connecting two first sub-brackets 1115 and one first sub-transverse beam 1117, and is connected with the first main transverse beam 1113 at the rear end of the first main frame 1111 to form the quadrilateral frame structure. Specifically, the two post-processor mounting brackets 121 are provided, one is disposed on the first main cross beam 1113 located at the front end of the first main frame 1111, and the other is disposed on the first sub cross beam 1117 of the first sub-bracket 1115, so that connection points of the post-processor 21 and the first frame portion 111 are located at the front end and the rear end of the first frame portion 111, respectively, which is beneficial to improving connection stability. Of course, the number of the post-processor mounts 121 may be other numbers than two, depending on the specific structure of the post-processor 21. In addition, the force distribution and stability of the quadrilateral frame structure are excellent, and the post-processor mounting frame 121 is convenient to arrange. Specifically, the post-processor mount 121 may take a shape as shown in fig. 1 and 4, that is, a structure having bent-down portions at both ends, so that when mounted on the frame assembly 11, the connection surface of the post-processor mount 121 to the post-processor 21 is higher than the top surface of the first frame section 111 to reserve an operation space for the assembly operation.
In a further embodiment of the present invention, as shown in fig. 1 to 3, in the post-processing installation platform 1, the second frame portion 112 includes a second main frame 1121 and a second sub-bracket 1125, and the second sub-bracket is connected to the front end of the second main frame 1121 in the longitudinal direction, on one hand, the size of the second frame portion 112 in the longitudinal direction can be increased, and on the other hand, the second frame portion 112 and the first sub-bracket can also be formed 1115 in a staggered arrangement, so as to reduce the possibility of mutual interference. The second main frame 1121 includes a plurality of second main longitudinal beams 1122 and a plurality of second main cross beams 1123, and the second sub-bracket 1125 includes a plurality of second sub-longitudinal beams 1126, for example, as shown in fig. 3, the second main frame 1121 may be connected by two second main longitudinal beams 1122 and two second main cross beams 1123 to form a quadrilateral frame structure, and the second sub-bracket 1125 may include two second sub-longitudinal beams 1126, and the two second sub-longitudinal beams 1126 are respectively disposed corresponding to the two second main longitudinal beams 1122.
The urea tank mounting brackets 122 are disposed in a plurality of numbers and are all disposed along the transverse direction, at least one urea tank mounting bracket 122 of the plurality of urea tank mounting brackets 122 is disposed on the second main longitudinal beam 1122, and the rest of the urea tank mounting brackets 122 are disposed on the second auxiliary longitudinal beam 1126, for example, two urea tank mounting brackets 122 illustrated in fig. 3 are disposed on the second main longitudinal beam 1122 and the second auxiliary longitudinal beam 1126, respectively, that is, one urea tank mounting bracket 122 is disposed above the second main frame 1121 along the transverse direction, and both ends of the one urea tank mounting bracket are connected with the two second main longitudinal beams 1122, and the other urea tank mounting bracket 122 is disposed above the second auxiliary bracket 1125 along the transverse direction, and both ends of the other urea tank mounting bracket 122 are connected with the two second auxiliary longitudinal beams 1126, so as to connect different positions on the urea tanks 22 through the two urea tank mounting brackets 122, so as to improve stability when being connected with the urea tanks 22, and to provide a sufficient mounting space for the air filter 23 behind the urea tanks 22. Specifically, the urea tank mount 122 may take a shape as shown in fig. 1 and 4, that is, a structure having bent-down portions at both ends, so that the connection surface of the urea tank mount 122 to the urea tank 22 is higher than the top surface of the second frame portion 112 when mounted on the frame assembly 11, to reserve an operation space for the assembly operation.
Further, as shown in fig. 3 and 4, the number of the air filter mounting brackets 123 is plural, for example, two as shown in fig. 3 and 4. The air filter mounting brackets 123 are connected to the second main cross beam 1123 at the rear end of the second main frame 1121, and each air filter mounting bracket 123 is disposed along the longitudinal direction and extends from the rear end to the front end of the second main frame 1121. A position on the air filter mounting bracket 123 near the rear end of the second main frame 1121 is provided with a connection hole for connecting the air filter 23, so that the air filter 23 is positioned at the rear of the second main frame 1121 after being assembled, and is offset from the installation position of the urea tank 22, so that the air filter 23 is positioned at the rear of the urea tank 22.
Further, as shown in fig. 3 and 4, the plurality of air filter mounts 123 includes at least one air filter first mount 1231. The first mounting rack 1231 of the air filter is located near the lateral outer side of the second main frame 1121 and extends from the rear end to the front end of the second main frame 1121, that is, both ends of the first mounting rack 1231 of the air filter are respectively connected with the two second main beams 1123 of the second main frame 1121, so as to increase the connection strength. Here, the laterally outer side of the second main frame 1121 refers to a side of the second main frame 1121 which is away from the first main frame 1111 in the lateral direction. As shown in fig. 3, the plurality of air filter mounts 123 specifically includes an air filter first mount 1231 and an air filter second mount 1232, wherein the air filter second mount 1232 is located between the air filter first mount 1231 and the first main frame 1111, and the rear end of the air filter second mount 1232 is connected to the corresponding second main beam 1123, and the front end of the air filter second mount 1232 is suspended to connect and support the air filter 23 through the air filter first mount 1231 and the air filter second mount 1232. In addition, in practical applications, according to different bearing requirements, the second mounting rack 1232 of the air filter can also be configured to have a structure similar to that of the first mounting rack 1231 of the air filter, that is, two ends of the second mounting rack are respectively connected to the two second main beams 1123, so as to further increase the connection strength.
It will be appreciated that conventional urea tanks are typically bulky and take up a relatively large amount of space, while air filters are typically of a relatively horizontally narrow configuration and may be arranged in a transverse direction (as in the example of figure 2) to reduce the space taken up in a longitudinal direction. Therefore, the urea tank mounting bracket 122 and the air filter mounting bracket 123 in the embodiment can be adapted to the structures of the urea tank and the air filter, which is beneficial to optimizing the space layout.
Correspondingly, as shown in fig. 4 to 6, the oil-water separator mounting frame 125 is connected to the first mounting frame 1231 of the air filter, and the oil-water separator mounting frame 125 extends below the first mounting frame 1231 of the air filter, so that the oil-water separator 25 is located below the first mounting frame 1231 of the air filter and laterally close to the lateral outer side of the first main frame 1111 after being connected to the oil-water separator 25, so as to facilitate the maintenance operation of the oil-water separator 25. The urea pump mount 124 is connected to a second secondary longitudinal beam 1126 adjacent the first main frame 1111 and the urea pump mount 124 extends below the second secondary longitudinal beam 1126 such that, when connected to the urea pump 24, the urea pump 24 is positioned below the second secondary longitudinal beam 1126 and adjacent the aftertreatment 21 and urea tank 22 for facilitating plumbing connections therebetween.
As shown in fig. 4 and 5, the urea pump mounts 124 and the oil-water separator mounts 125 are disposed in a staggered manner in the longitudinal direction and the transverse direction, and the urea pump mounts 124 are disposed at the front portion of the second frame portion 112, so that the urea pump 24 can be maintained in front of the second frame portion 112, and convenience of maintenance operation is further improved.
In further embodiments of the present invention, as shown in fig. 3-6, the frame assembly 11 further comprises a first stiffener 1131, and/or a second stiffener 1132, and/or a water pipe bracket mounting bracket 1133, and/or a wiring structure 1134 in the aftertreatment mounting platform 1.
A first reinforcement 1131 is disposed at the connection between the first secondary support 1115 and the first main frame 1111, for example, the first reinforcement 1131 may be located inside the first secondary support 1115, and both ends of the first reinforcement are connected to the first secondary longitudinal beam 1116 and the first main transverse beam 1113 respectively; alternatively, the first stiffener 1131 may be located outside the first subframe 1115, and both ends of the first stiffener 1116 and the second main beam 1123 are connected to the first sub-longitudinal beam 1116 and the second sub-lateral beam 1123, respectively. Of course, the number of the first reinforcements 1131 may also be multiple, and the first reinforcements 1131 may also be disposed at other positions of the first secondary support 1115 according to the strength requirement, for example, at the connection between the first secondary longitudinal beam 1116 and the first secondary cross beam 1117 shown in fig. 3.
Similarly, a second reinforcement 1132 is provided at the connection of the second frame part 112 and the first frame part 111, such as in the example of fig. 3, the second reinforcement 1132 is provided at the connection of the second sub-longitudinal beam 1126 and the corresponding first main transverse beam 1113 to increase the connection strength; of course, the number of the second reinforcements 1132 may also be multiple, and the second reinforcements 1132 may be arranged between the second sub-longitudinal beam 1126 and the second main cross beam 1123 or at other joints according to the strength requirement.
The first reinforcement 1131 and the second reinforcement 1132 include, but are not limited to, a plate-like structure and a rod-like structure, and may have other shapes and structures capable of reinforcing the connection operation.
Water tube bracket mounts 1133 are provided at the rear end of first secondary bracket 1115, such as in the example of FIG. 3. Water tube bracket mounts 1133 may specifically be located on first secondary cross member 1117 and extend rearwardly to facilitate mounting of water tube brackets for securing water tubes.
A wiring structure 1134 is provided on the second frame portion 112 near the first main frame 1111, for example, as in the example of fig. 3, and the wiring structure 1134 is located on the second main longitudinal beam 1122 on the second frame portion 112 near the first main frame 1111. The number of the wiring structures 1134 may be plural, and the wiring structures are arranged at intervals along the longitudinal direction for fixing the cables; in addition, a wiring structure 1134 may also be correspondingly disposed on the second sub longitudinal beam 1126.
Further, in any of the above embodiments, as shown in fig. 3, the first main frame 1111 and the second main frame 1121 may be an integrated structure, that is, the first main cross beam 1113 and the corresponding second main cross beam 1123 are different parts on the same cross beam, and the first main longitudinal beam 1112 and the second main longitudinal beam 1122 at the connection point of the first main frame 1111 and the second main frame 1121 share the same longitudinal beam, that is, the longitudinal beam is both the first main longitudinal beam 1112 and the second main longitudinal beam 1122. The arrangement can reduce the connection points between the first main frame 1111 and the second main frame 1121, which is beneficial to simplifying the processing process and improving the overall strength.
