Description

Technical Field

[0001] The invention relates to the technical field of engine exhaust and muffler, and in particular to an exhaust muffler component for a high-power engine. Background Art

[0002] High-power engines are generally used in the fields of ships, mining, surveying, etc., where the road conditions are generally bad and the degree of bumps is generally large. The exhaust system is the part of the entire engine that handles the exhaust gas. Due to the particularity of its function, it is generally installed at a high position on the engine, and the installation method is often stacked on the engine through multiple parts such as brackets. During the use of the engine, the vibration of the engine is generally large, and the exhaust system is at a high position, which leads to the exhaust system often vibrating due to excessive vibration, loosening of installation parts, and even falling off. Previously, there were also multi-angle reinforcement solutions that tried to solve this problem. Although it can solve the reinforcement problem, the increase in weight not only brings an increase in cost, but also affects the installation of exhaust system parts, resulting in low installation efficiency and difficult operation. The installation accuracy of the entire exhaust system cannot be guaranteed. At the same time, with the increasing integration of current engines, the space is getting smaller and smaller, and the required space utilization rate is higher. When designing an engine, the low space utilization also poses challenges to the vibration resistance, firmness and reliability of exhaust system parts such as brackets. How to significantly improve the stability and reliability of parts such as brackets while meeting the current compression of engine space is a major technical problem that the current engine industry urgently needs to solve. Although there are some bracket structures currently used in the market, the force distribution of the brackets is not reasonable enough, so the vibration resistance, service life and reliability cannot meet the requirements. At the same time, during assembly, most of the adjustments and installations are based on the experience of technicians, and the use of existing measuring tools for installation is not only unable to be used normally due to limited space, but also cumbersome and not conducive to industrial assembly operations. Summary of the invention

[0003] In view of the above technical problems, the present invention provides an exhaust silencer assembly for a high-power engine with reliable structure and scientific assembly.

[0004] To achieve the above object, the present invention adopts the following technical solution:

[0005] An exhaust silencer assembly for a high-power engine comprises a silencer bracket, an L-shaped exhaust pipe semicircular clamping piece and an L-shaped exhaust pipe support seat; the silencer bracket comprises a support plate, a plurality of silencer fixing holes are formed on the support plate, and an L-shaped exhaust pipe clearance opening is also formed at the front end thereof; a support fixing plate is vertically combined with a support fixing plate on the lower left side of the support plate, and a plurality of fixing holes are formed on the support fixing plate; waist-shaped holes are formed on both sides of the L-shaped exhaust pipe clearance opening, the L-shaped exhaust pipe semicircular clamping piece is correspondingly distributed on one side of the L-shaped exhaust pipe clearance opening and is clamped on the L-shaped exhaust pipe, and is tightened to the waist-shaped hole by bolts; the L-shaped exhaust pipe support seat is supported and fixed on the lower part of the L-shaped exhaust pipe.

[0007] Furthermore, a support hole is provided on the right side of the support plate, and a support column is provided corresponding to the support hole, and the lower end of the support column is connected and fixed to the engine cylinder body.

[0008] Furthermore, it also includes a precision installation tool, which includes a bracket bonding plate, and the bracket bonding plate is also provided with a plurality of bracket fixing holes, and the bracket fixing holes correspond to the fixing holes of a certain type of muffler; a U-shaped groove is provided in the middle of the right side of the bracket bonding plate corresponding to the L-shaped exhaust pipe; an L-shaped exhaust pipe cap is also provided corresponding to the U-shaped groove, and the exterior of the L-shaped exhaust pipe cap is a rectangular structure, and a circular recessed hole is provided from the lower part thereof corresponding to the L-shaped exhaust pipe, and a handle is also provided on the top; the U-shaped groove matches the yield opening of the L-shaped exhaust pipe, and the size of the U-shaped groove is larger than the size of the exterior of the L-shaped exhaust pipe cap.

[0009] Furthermore, a verticality distance detector is respectively provided on the rear side and the left side of the U-shaped groove; the verticality distance detector comprises a connecting seat, on which connecting bolts are distributed; one side of the connecting seat is connected to a telescopic arm support rod, and a telescopic arm slot is provided inside the telescopic arm support rod; a spring and a telescopic arm are distributed in the telescopic arm slot; the spring presses the telescopic arm outward, and a tightening bolt is correspondingly distributed at the outer end of the telescopic arm slot, and the tightening bolt is used to press and fix the telescopic arm; the outer end of the telescopic arm is rotatably connected to a verticality detection block through a rotating shaft.

[0010] Furthermore, the verticality detection block is in the form of a rectangular column structure, and a transparent angle ruler is provided on the inner side thereof.

[0011] Furthermore, the telescopic arm is provided with a scale line corresponding to the transparent angle ruler, and the telescopic arm is also provided with a telescopic degree scale.

[0012] The beneficial effects of the present invention compared with the prior art are as follows:

[0013] (1) The present invention uses a support plate and a support fixing plate to form an L-shaped structure, which greatly saves the space occupied by the bracket in the engine. Then, the support fixing plate and the support column are used to achieve stable support, and the L-shaped exhaust pipe semicircular clamping piece is used to clamp and fix it onto the L-shaped exhaust pipe as the vibration reduction support point at the other end, that is, a triangular support structure is formed by using a surface + point. This not only greatly reduces the space occupancy rate, but also significantly improves the stability and support rigidity of the entire support structure. The support point of the L-shaped exhaust pipe semicircular clamping piece is pressed onto the L-shaped exhaust pipe, which can effectively reduce the vibration of the entire muffler bracket and the L-shaped exhaust pipe after the muffler is installed, thereby improving reliability.

[0014] (2) To solve the problem of installation accuracy, this precision installation tool is provided with a bracket bonding plate to simulate the assembly of the muffler installation body, and then the L-shaped exhaust pipe cap and the verticality distance detector are used to achieve accurate alignment of the L-shaped exhaust pipe, the muffler bracket and the muffler, so as to prevent excessive local stress due to inaccurate installation after the traditional installation torque is tightened, and the phenomenon of loose bolts, large vibration or partial shell tearing due to long-term bumpy operation on mining, surveying and other road conditions can be achieved. During assembly, it can achieve rapid, efficient and intuitive measurement of the verticality and spacing between the muffler bracket, the muffler and the L-shaped exhaust pipe (round pipe), which is convenient for the compression installation of the L-shaped exhaust pipe in combination with the L-shaped exhaust pipe semicircular clamp. For the assembly components of the special muffler bracket and the L-shaped exhaust pipe semicircular clamp, the traditional problems such as elimination of local stress after assembly, low vibration during operation, and less prone to partial shell tearing can be eliminated, and the use effect is good.
