Coal mine connecting pin and connecting chain horizontal tensile machine

This equipment is a horizontal tensile testing machine developed by our company for testing the tension of connecting pins and connecting chains of narrow-gauge vehicles in coal mines.It complies with the industry standard "AQ1112-2014" monitoring specifications for the connection chain of narrow-gauge vehicles in use in coal mines and the industry standard "AQ1113-2014" monitoring specifications for the connection pins of narrow-gauge vehicles in use in coal mines.

The mine car pin chain horizontal tensile testing machine is mainly composed of the main machine (frame structure), the mine car entering mechanism, pin chain tensioning aids, loading cylinder, servo oil source, servo controller, as well as related test software and other necessary accessories.

The testing machine adopts a four-column horizontal frame structure, an automatic mine car entry and exit mechanism, a single rod and a double-acting piston cylinder to apply the test force, and automatically controls the test process. The load sensor measures the force, and the microcomputer displays the test force and test curve.

The main engine part is mainly composed of the rear beam, double columns, cylinder base, cylinder piston, pin chain auxiliary equipment, load sensor and other components.The cylinder base, double columns and rear beam form a stress-bearing frame. The single-rod double-acting low-friction piston cylinder generates a test force of 2000kN under the action of high-pressure oil.

When doing chain stretch testing, use the front and rear clamps and use Undo to stretch.

When doing the pin stretch test, connect the pin stretch auxiliary tool to the rear clamp, and perform the stretch test on the pin together with the front clamp.

This part is the execution component of the test.The two ends of the sample are installed in the fixtures on the fixed beam and the movable beam respectively, and then the thrust cylinder drives the movable beam to apply test force to the sample.Automatically control the loading speed until the end of the test.
