Description

Technical Field

[0002] The rudder stock mechanism refers to a mechanical device used to control the rotation of the rudder blade, which is usually composed of a rudder stock, a tiller, a steering device, etc. The function of the rudder stock mechanism is to convert the driver's operating instructions into the rotation of the rudder blade, thereby realizing the steering of the ship; when the driver turns the tiller, the tiller drives the rudder stock to rotate through the steering device, and the rudder stock then drives the rudder blade to rotate, thereby changing the course of the ship; the quality of the rudder stock mechanism is very important, and it is necessary to conduct simulation tests based on the use of different ships in different environments, such as driving a ship in an extremely cold environment. Therefore, it is necessary to repeatedly test and analyze the tensile force, low-temperature resistance and other characteristics of the ship rudder stock mechanism material under low-temperature conditions in an extremely cold environment, providing a platform for material research.

The test module performs a tensile test through a unit to be buffered and a test unit. In the tensile testing machine of the present application, the test module uses the unit to be buffered and the test unit to achieve tensile and thrust tests, which on the one hand reduces the probability of injury incidents during manual testing, and on the other hand reduces the impact that may be caused by rebound at the end of the tensile test, thereby improving the safety of the test. Moreover, the carrier module further cooperates with the auxiliary fixing unit and the clamp provided therein to achieve fixation of a variety of different samples, so that the tensile testing machine can test a variety of different samples to improve work efficiency;
