Detailed Description

Referring to fig. 2, the present invention discloses an exhaust aftertreatment package 100, which includes an air inlet flange 1, an air inlet pipe 2 connected to the air inlet flange 1, a hook assembly 3, a catalyst assembly 4, an air outlet end cone 5 connected to the catalyst assembly 4, and an air outlet pipe 6 connected to the air outlet end cone 5.

Referring to fig. 3 to 5, the hook assembly 3 includes an air inlet end cone 30, and a first hook 31 and a second hook 32 mounted on the air inlet end cone 30. The inlet end cone 30 is connected between the inlet pipe 2 and the catalyst assembly 4.

In addition, the exhaust aftertreatment package 100 further includes a sensor mount 21 welded and fixed to the intake pipe 2.

In one embodiment of the present invention, the catalyst assembly 4 includes three-way catalyst packages 41 and particle trap packages 42 disposed at intervals. The exhaust aftertreatment package 100 further includes a differential pressure pipe 43, one end of the differential pressure pipe 43 is welded to the intake pipe 2, and the other end of the differential pressure pipe 43 is welded between the three-way catalyst package 41 and the particle trap package 42. Of course, both ends of the differential pressure pipe 43 extend into the exhaust aftertreatment package 100 to measure the pressure difference of the exhaust gas.

The tapered surface of the inlet end cone 30 is formed with a first welding plane 301 and a second welding plane 302. The first hook 31 and the second hook 32 are welded to a fixture as a whole, and then welded to the inlet end cone 30. Specifically, the first hook 31 is provided with a first welding portion 311 welded and fixed to the first welding plane 301, and the second hook 32 is provided with a second welding portion 321 welded and fixed to the second welding plane 302. So set up, avoided because the contact surface is the poor problem of welding quality that the cambered surface leads to. Such a process sequence is simple, so that the first hook 31 and the second hook 32 can be welded to the inlet end cone 30 conveniently, and the production efficiency can be improved.

In the illustrated embodiment of the present invention, the first welding plane 301 is a boss formed by pressing the tapered surface of the inlet end cone 30 outward, and the second welding plane 302 is a boss formed by pressing the tapered surface of the inlet end cone 30 outward.

The first hook 31 is provided with a first bending portion 312 formed by bending two ends of the first welding portion 311, and a first welding rod 313 formed by bending the first bending portion 312.

The second hook 32 is provided with second bent portions 322 respectively bent from two ends of the second welding portion 321, and a suspension rod 323 for being engaged with a lifting lug 7 (see fig. 2) is formed at a distal end of the second bent portions 322.

The first welding rod 313 is welded and fixed to the second bent portion 322.
