Description
Technical Field
[0001] This utility model belongs to the field of vehicle engine exhaust emission purification technology and energy saving and consumption reduction technology, and specifically relates to a U-shaped vertically arranged off-road after-treatment structure. Background Technology
[0002] To reduce the emission of harmful substances in engine exhaust, non-road machinery must have an after-treatment system installed behind the engine.
[0003] Most existing off-road reprocessors are arranged vertically in a straight line or horizontally in a U-shape. However, in some cases, the limited height and lateral space make it difficult to arrange the reprocessor and its supporting pipelines. Furthermore, vertically arranged reprocessors are too tall to be effectively fixed by bottom connection alone, so side bracing is usually added. However, in some scenarios, there is no side bracing to fix the position. Summary of the Invention
[0004] This utility model provides a U-shaped vertically arranged off-road post-processing structure, the purpose of which is to overcome the shortcomings of the existing technology, and is superior to the existing post-processor structure in terms of space utilization and structural protection function.

The right cylinder contains, from bottom to top, a selective catalytic reduction unit and an air outlet. The mixer and the selective catalytic reduction unit are connected by a pipeline in the middle of the cylinder. The left and right cylinders are connected by a connector and a clamp.
[0008] The wrap-around bracket is a frame structure composed of several square steel bars connected together;
[0009] The lower part of the wrap-around bracket is a square frame, and L-shaped support plates are welded to the front and rear square steel bars of the square frame.

The tops of the two square steel bars at the back are connected to the horizontal square steel bars. The middle of the two square steel bars at the front are connected to the horizontal square steel bars.
[0011] The main body of the post-processor is placed inside a wrap-around bracket and connected to each other;
[0012] The lower part of the cylinder of the post-processor body is placed on the L-shaped support plate; there is an L-shaped connecting plate at the front and back of the lower part of each cylinder. One side of the L-shaped connecting plate is an arc surface that is welded to the cylinder. The other side of the L-shaped connecting plate has a through hole and is fastened to the corresponding through hole on the L-shaped support plate using a combination of bolts and nuts.
[0013] The upper part of the cylinder is connected to the wrap-around bracket by a side-pull bracket;
[0014] The side tension bracket consists of a clamp and a connecting bracket, the connecting bracket being a U-shaped body with a U-shaped groove;
[0015] The upper part of the hoop is inserted into the U-shaped groove of the connecting bracket, and the hoop and the connecting bracket are connected by a pin;
[0016] The lower part of the hoop grips the cylinder and is secured by T-bolts passing through the two ends of the lower part of the hoop.
[0017] Nuts are welded inside the bottom of the U-shaped groove of the connecting bracket. Bolts are screwed into the nuts after passing through the through holes of the square steel and the connecting bracket, and the connecting bracket and the square steel are fastened together.
[0018] Furthermore, the adjacent square steels of the wrap-around bracket are connected to each other, and the two vertical sides of the L-shaped plate abut against the adjacent square steels respectively. The square steels and the L-shaped plates that abut against them are connected by a combination of bolts and nuts, thereby connecting the adjacent square steels.
[0019] Furthermore, the front and rear square steel bars of the lower square frame of the wrap-around bracket each have several through holes for connecting to the corresponding positions in the engine compartment.
[0020] Furthermore, the two sides of the stiffening plate abut against the two adjacent sides of the L-shaped support plate and are welded together.
[0021] Furthermore, lifting lugs are installed on the front and rear square steel for easy hoisting. Beneficial effects
[0022] This invention is superior to the vertically arranged post-processor in terms of height space utilization and superior to the U-shaped horizontally arranged post-processor in terms of lateral space utilization.

[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0030] like Figure 2 As shown:
[0031] The main body 1 of the post-processor is arranged vertically and has two cylinders. The left cylinder contains, from top to bottom, an air inlet 11, an oxidation catalyst 12, a particle collector 13, and a mixer 14. The right cylinder contains, from bottom to top, a selective catalytic reduction unit 16 and an air outlet 17. The mixer 14 and the selective catalytic reduction unit 16 are connected by a pipeline in the middle of the cylinder. The left and right cylinders are connected by a joint and clamp.
[0032] In use, the airflow enters from the inlet 11 and flows downwards through the oxidation catalyst 12, the particulate collector 13, and the mixer 14, then enters the selective catalytic reducer 16 through the middle pipe of the cylinder, and finally exits upwards from the outlet 17.
[0033] like Figure 3 As shown:
[0034] The wrap-around bracket 2 is a frame structure composed of several square steel bars 21. The square steel bars used for the wrap-around bracket can be selected from different materials and sizes according to requirements, and can be 40mm or 50mm wide, and 3mm or 2mm thick;
[0035] Adjacent square steel bars 21 are connected to each other, and the two vertical sides of the L-shaped plate 22 abut against the adjacent square steel bars 21 respectively. The square steel bars 21 and the L-shaped plate 22 abutting against them are connected by bolt and nut combination, thereby connecting the adjacent square steel bars 21.
[0036] The lower part of the wrap-around bracket 2 is a square frame composed of four square steel bars 21. Each of the front and rear square steel bars 21 of the square frame has three through holes 24, for a total of six through holes 24 for connection with the corresponding position in the engine compartment.
[0037] Two square steel bars 21 are connected to two L-shaped trays 26, and each L-shaped tray 26 has a through hole 27 for connecting the post-processor.
[0038] like Figure 4 As shown: The welding edge 261 of the L-shaped pallet 26 is welded to the square steel 21.
[0039] The two sides 281 of the stiffening plate 28 abut against the two adjacent sides of the L-shaped support plate 26 and are welded together. The function of the stiffening plate 28 is to strengthen the L-shaped support plate 26 to bear the weight of the post-processor body 1.
[0040] The lower part of the wrap-type bracket 2 has a square frame composed of four square steel bars 21. The four corners are connected to the vertical square steel bars 21 respectively. The tops of the left and right square steel bars 21 are connected to the front and back square steel bars 21. Lifting lugs for easy hoisting are installed on the front and back square steel bars.
[0041] The tops of the two rear square steel bars 21 are connected by a transverse square steel bar 21.
[0042] The two front square steel bars 21 are connected in the middle by a horizontal square steel bar 21, which has four through holes 23 for connecting to the rear processor side pull bracket.
[0043] The connection between adjacent square steel bars 21 can be either the prefabricated type described above or a welded connection.
[0044] like Figure 1 As shown:
[0045] The post-processor body 1 is placed inside the wrap-around bracket 2 and connected to each other.
[0046] The connection structure is as follows:
[0047] like Figure 4 , Figure 5 As shown:
[0048] The post-processor body 1 has two cylinders A.
[0049] The lower part of cylinder A is placed on two L-shaped support plates 26 at the front and rear.
[0050] Each cylinder A has an L-shaped connecting plate 31 at the front and back of its bottom. One side of the L-shaped connecting plate 31 is curved and welded to the cylinder A. The other side of the L-shaped connecting plate 31 has a through hole and is fastened to the corresponding through hole 27 on the L-shaped support plate 26 using a bolt and nut combination 32 to ensure that the bottom is securely installed.
[0051] In this way, the lower part of the cylinder A is fixed on the wrap-around bracket 2.
[0052] like Figure 6 As shown:
[0053] The upper half of each of the two cylinders A is connected to the wrap-around bracket 2 by a side-pull bracket.
[0054] The side-pull bracket consists of a clamp 42 and a connecting bracket 41, the connecting bracket 41 being a U-shaped body with a U-shaped groove.
[0055] The upper part of the clamp 42 is inserted into the U-shaped groove of the connecting bracket 41, and the pin 44 passes through the corresponding through holes of the clamp 42 and the connecting bracket 41, so that the clamp 42 and the connecting bracket 41 are connected.
[0056] The lower part of the hoop 42 hugs the cylinder A and is secured by T-bolts 43 passing through the two ends of the lower part of the hoop 42.
[0057] A nut (not shown in the figure) is welded inside the U-shaped groove of the connecting bracket 41. After the bolt passes through the through hole 23 of the square steel 21 and the corresponding through hole of the connecting bracket 41, the nut is screwed in. The connecting bracket 41 and the square steel 21 are fastened together to ensure that the side pull bracket is securely installed on the wrap-around bracket 2.
[0058] Thus, the upper part of cylinder A is connected to the wrap-around bracket 2.
[0059] The connection between cylinder A and the side support can be either the assembly method described above or a direct welding connection.
[0060] In this way, the present invention is superior to the vertical arrangement of the post-processor in terms of height space utilization and superior to the U-shaped horizontal arrangement of the post-processor in terms of horizontal space utilization. Moreover, the wrap-around bracket structure not only provides a fixed position for the side pull bracket, but also provides structural protection for the post-processed products, ensuring stability and safety.
