Problems solved by technology

During the engine test, due to the large vibration of the engine, the connection stress of the exhaust device increases, which causes the exhaust elbow to loosen and cause an accident, or the high-temperature exhaust elbow falls off and causes a fire accident on the bench. security is not guaranteed
In addition, loose exhaust pipes and exhaust elbows are prone to wear and tear, which increases the cost of test tooling
At present, the traditional exhaust device can no longer meet the increasing test tasks and the production requirements of high efficiency, safety and low cost

Embodiment Construction

[0028] The present invention will be further described below in conjunction with the specific embodiments in the accompanying drawings.

[0029] refer to Figure 1-8 , a flexible exhaust connection device of the present invention includes an axially telescopic and bendable flexible pipe body 1 connected to the bench exhaust main pipe, and the main body of the flexible pipe body 1 adopts a corrugated pipe with foldable corrugated sheets. When installing, stretch the foldable corrugated sheet to both ends of the bellows to extend the exhaust pipe; compress the foldable corrugated sheet to both ends of the bellows to compress the exhaust pipe; stretch the folded corrugated sheet to one side of the connection position and compress the other The generated displacement difference can make the bellows bend to the direction of compression; it can realize stretching and elongation at any position of the exhaust connection device as a whole and change the angle, and the dynamic adjustme...

Abstract

The invention discloses a flexible exhaust connection device, which comprises an axially telescopic and bendable flexible pipe body connected to the main exhaust pipe of the platform, and a rigid elbow connected to the exhaust outlet of the engine. The elbow It is connected with the flexible pipe body through an adjustment mechanism, which can be rotated and adjusted by 360°. The flexible exhaust connection device of the present invention has a simple structure, can realize dynamic adjustment in three-dimensional space, is convenient for installation, and is convenient for real-time monitoring of engine tests, and has a wide range of applications.

Description

technical field [0001] The invention relates to the field of engine testing devices, more specifically, it relates to a flexible exhaust connection device. Background technique [0002] The traditional exhaust device is a connection device that connects the exhaust elbow tooling to the corresponding engine exhaust manifold, and the other end of the exhaust elbow is directly inserted into the exhaust pipe of the bench. Since the exhaust pipe of the bench is installed from the top of the bench and hangs upside down in the bench, when installing the exhaust elbow on the engine bench, it often takes a lot of effort to insert the exhaust elbow into the exhaust pipe. , and its fixing method is exactly to support with support, then binds with iron wire, and the labor intensity of operator is very big. During the engine test, due to the large vibration of the engine, the connection stress of the exhaust device increases, which causes the exhaust elbow to loosen and cause an acciden...
