Description

Shockproof structure for diesel engine cylinder cover stud

Technical Field

The utility model belongs to the technical field of diesel engine accessories, and particularly relates to a shockproof structure for a diesel engine cylinder cover stud, which is applied to the diesel engine cylinder cover stud and is connected with the cylinder cover stud in series to prevent the stud from cracking caused by vibration during the running of a diesel engine.

Background

Diesel engines are a huge host that is operated continuously as a motive power for providing sailing of ships. However, a huge engine needs a huge explosion force to start, and a cylinder head stud is a device which is installed on a cylinder head of a diesel engine and is connected to a cylinder body to fix a cylinder head of the engine.

With the continuous upgrading of the performance of the diesel engine host, the requirements on parts of various parts of the diesel engine are higher. The new diesel engine main engine has a certain degree of improvement on the explosion pressure requirement. Under the condition of 5% -10%, the stud is broken at the lower end, and the energy is released by pushing the stud upwards, so that when the stud moves upwards or descends again rapidly, the stud can hit a person to cause injury.

Patent document CN203050904U discloses a connection structure on engine cylinder cover, including the connecting portion of engine cylinder cover border department and run through in the connecting hole of connecting portion, connecting hole department has linked firmly and has been cylindric sheath, and the sheath is used for the cover to be in the fastener outside that makes cylinder body and cylinder cover link to each other, has advantages such as the internal thread wearing and tearing in the cylinder cover connecting hole and cylinder cover long service life of reduction. However, each cylinder head stud is still stressed independently, and the breakage of each stud caused by stress concentration cannot be avoided.

Disclosure of utility model

In order to overcome the defects in the prior art, the utility model provides the shockproof fixing support which is suitable for the stud of the cylinder cover of the diesel engine, can effectively improve the problem of stress concentration caused by vibration, works in a long-term high-pressure environment, and avoids the possibility of stud breakage.

In order to achieve the above object, the technical solution of the present utility model is as follows:

A shockproof structure for a diesel engine cylinder cover stud is characterized by comprising a plurality of connecting pieces and connecting plates; each connecting piece comprises a pipe clamp, a flat plate and a gasket, wherein the pipe clamp is in an inverted U shape, the flat plate is positioned below the pipe clamp, threaded holes are formed in two ends of the flat plate, and the flat plate is connected with the pipe clamp through nuts and bolts; the gasket is positioned in the U-shaped opening of the pipe clamp and used for wrapping the cylinder cover stud;

Waist-shaped holes are respectively formed at two ends of the connecting plate and are connected with the flat plate through nuts and bolts;

the connecting pieces of the adjacent two cylinder cover studs are connected through the connecting plates, so that all the cylinder cover studs are stressed simultaneously, and stress concentration is avoided.

Further, the connecting plate is in a bent shape and is matched with the shape of the cylinder cover of the diesel engine.

Compared with the prior art, the utility model has the beneficial effects that when the stud moves upwards or descends again, the stress release can be greatly reduced, and the high-pressure severe working environment can be well satisfied.
