Description

Technical Field

[0001] The utility model belongs to the technical field of engineering machinery, and in particular relates to a post-processing mounting bracket. Background Art

[0002] At present, with the implementation of the fourth stage emission regulations for non-road engineering machinery, most non-road engineering machinery must be equipped with exhaust gas after-treatment equipment. Some require the after-treatment device to be fixed separately by the whole machine factory. Compared with integration on the engine, this arrangement has the characteristics of less vibration and more stability. However, the strength requirements of the bracket are relatively high, and the designed bracket will have problems such as poor lightweight, difficult assembly, and poor stability.

[0003] In the existing structure, it is difficult to realize the post-processing interface and the interface fixed to the frame with one frame under the consideration of the overall layout. Most of them are realized by welding a 10mm thick steel plate on the frame to achieve the requirements of fixing the post-processing and installing it on the frame. However, the disadvantages caused by this layout are: the structure is heavy, the strength is low, the lightweight is not good, and the stability is low.

[0004] For example, a Chinese utility model patent with authorization announcement number CN 213627758 U discloses a post-processor mounting bracket assembly, in which the post-processor 2 is installed below the connecting bracket 3 in a suspended manner, resulting in the other end of the connecting bracket 3 having no support. When the construction machinery vibrates during long-term work, it is easy to fall and damage other equipment, so its strength is low and stability is poor. Utility Model Content

[0005] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a post-processing mounting bracket.

[0006] In order to achieve the above purpose, the utility model is implemented by adopting the following technical solutions:

[0007] A post-processing mounting bracket comprises a top frame and N legs, wherein the top frame is connected to the upper ends of the legs via a mounting seat, the lower ends of the legs are provided with brackets for assembly and connection with a rear frame, the top frame is provided with fasteners for mounting a post-processing device, and the mounting seat is a box-type structure, wherein N is a positive integer greater than or equal to 2.

[0008] Preferably, the top frame comprises two longitudinal beams and two transverse beams which are embedded and welded to each other, and the two longitudinal beams and the two transverse beams form a rectangular frame structure.

[0009] Preferably, the longitudinal beam is a U-shaped plate, and the transverse beam is a square tube profile.

[0010] Preferably, the mounting seat comprises side blocking plates, a top plate and a short square tube, the side blocking plates, the top plate and the short square tube are welded to form a box-type structure, and the short square tube is welded to the crossbeam through a fully threaded thread seat.

[0011] Preferably, the bracket is provided with an elongated hole, and the bracket is assembled and connected to the rear frame via the elongated hole and bolts.

[0012] Preferably, N=4.

[0013] Preferably, the fastener is a welding nut or a wire seat.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. The four legs and the top frame are assembled, which is easy to assemble;

[0016] 2. Two longitudinal beams and two cross beams are embedded and welded together, and the two longitudinal beams and two cross beams form a rectangular frame structure, forming a core frame to support the post-processing equipment. The profiles are used to bear the force instead of the steel plates, and the structure has high strength. The 10mm thick welded steel plate is cancelled, which can achieve a weight reduction of more than 25Kg;

[0017] 3. Drill holes on the longitudinal beams to weld nuts and install post-processing equipment. The processing accuracy is easy to ensure, and the use requirements can be met through pre-welding processing;

[0018] 4. The mounting base adopts short square tubes and beams welded together to form a box-type structure. The position of the four legs can be realized by changing the length and position of the short square tubes, making the layout flexible and the structural application range wide;

[0019] 5. The mounting base is made of short square tubes and welded with three steel plates to form a whole with the top frame, so that the overall weld is stressed and the structure has high strength.

[0020] In summary, the utility model has a simple structure, high structural strength, good lightness, and is easy to process and assemble. BRIEF DESCRIPTION OF THE DRAWINGS
