Currently, engine exhaust pipes use ribs to inhibit deformation. The blast pipe structure weight after setting up the strengthening rib is big, and intensity is too high, under the condition of being heated, excessively restraines the horizontal extension of blast pipe, makes the blast pipe produce moulding deformation easily, leads to the blast pipe bolt to receive shear stress and fracture even, causes the gasket dislocation of blast pipe flange department simultaneously, and is sealed not tight, causes the leakage, influences dynamic property and outward appearance. In addition, the reinforcing ribs are added to cause difficulty in assembling the heat shield, and the heat insulation effect is poor.
Therefore, how to provide a novel exhaust pipe reinforcing structure to reduce the deformation of the exhaust pipe and increase the reliability of the exhaust pipe is a problem to be solved urgently by those skilled in the art.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide an exhaust pipe additional strengthening and vehicle can reduce the blast pipe and warp, increases the blast pipe reliability.
In order to solve the technical problem, the utility model provides a blast pipe additional strengthening, including the take-up plate that is used for connecting adjacent a plurality of blast pipe flanges, the take-up plate with the bolt hole has been seted up on blast pipe flange joint's the relative position.

Detailed Description
The core of the utility model is to provide an exhaust pipe additional strengthening and vehicle can reduce the blast pipe and warp, increases the blast pipe reliability.
In order to make those skilled in the art better understand the technical solutions provided by the present invention, the present invention will be further described in detail with reference to the accompanying drawings and specific embodiments.
Referring to fig. 1-3, the present invention provides an exhaust pipe reinforcing structure, which includes a tension plate 201 for connecting a plurality of exhaust pipe flanges, the tension plate 201 is provided with bolt holes at positions opposite to the exhaust pipe flanges, and bolts 3 connect the tension plate 201 and the exhaust pipe flanges together through the bolt holes of the tension plate 201.
Tensioning plate 201 and bolt cooperation can provide the horizontal tension who overcomes the material thermal expansion, restrain the blast pipe flange and warp to replaced the traditional mode that adopts strengthening rib increase intensity, solved 1 back of removing the strengthening rib of blast pipe, the blast pipe flange that causes after weakening of the flange intensity between blast pipe and the cylinder cap warp, blast pipe gasket dislocation, the blast pipe bolt receives shear stress's problem.
Under the prerequisite that does not change 1 self structural internal stress of blast pipe in this scheme, through increasing taut board 201, supplementary taut blast pipe flange reaches and reduces blast pipe and blast pipe flange deformation, increases the purpose of blast pipe reliability.
The exhaust pipe reinforcing structure can be an integrated structure, and all exhaust pipe flanges on the same side of the exhaust pipe 1 can be connected to one tensioning plate 201 at the same time.
The exhaust pipe reinforcing structure may also be formed by overlapping a plurality of tension plates 201 end to end. Each tension plate 201 may connect at least two adjacent exhaust pipe flanges. Two adjacent tensioning plates 201 are overlapped at the bolt holes of the connecting ends and connected through bolts 3. For the exhaust pipe 1 having a large size, a plurality of small-sized tension plates 201 may be overlapped to form one large-sized tension plate 201.
In a preferred embodiment, in order to increase the connection strength of the bolt 3 and the exhaust pipe reinforcing structure and increase the force-bearing area, the present scheme further includes a reinforcing cylinder 202 disposed on the tension plate 201, and the through hole of the reinforcing cylinder 202 is communicated with the bolt hole. The bolts 3 pass through bolt holes on the tensioning plate 201 and through holes of the reinforcing cylinder 202 to be connected with the exhaust pipe flange.
Specifically, when the bolt holes on the tension plate 201 correspond to the bolt holes on the exhaust pipe flange one by one, the reinforcement cylinder 202 is provided at each of the bolt holes on the tension plate 201. When there are more bolt holes in the tension plate 201 than in the exhaust pipe flange, the reinforcement cylinder 202 is provided only at the bolt holes in the tension plate 201 to be connected using the bolts 3.
The reinforcing cylinder 202 and the tension plate 201 are integrally formed, so that the manufacturing is easy and the connection is stable. Of course, the reinforcing cylinder 202 and the tension plate 201 can be in a split structure, and are easy to repair and replace.
The purpose of this scheme is through increasing blast pipe additional strengthening, restraines the deformation of blast pipe flange, and the main technical problem who solves lies in can increasing the reliability of blast pipe, can reduce the gas leakage risk again, has compromise when having guaranteed blast pipe intensity and leakproofness, and then the protective properties alleviates complete machine weight.
