Abstract

The invention provides a safety rope breaking strength detection fixture and a tester. The fixture comprises a base, a winding wheel, a connector and a pin. The base comprises a horizontal part and a vertical part, and the vertical part is vertically fixed to one side of the bottom surface of the horizontal part. The winding wheel is provided with a spiral winding groove, and one end of the winding wheel is fixed to the vertical part and is parallel to the horizontal part. The connector is fixed to the upper surface of the horizontal part, the pin is fixed to the side face, opposite to the vertical part, of the horizontal part and is parallel to the horizontal part, one end of a test rope is wound in the winding groove of the winding wheel, and the end of the test rope is fixed to the pin. According to the safety rope breaking strength detection fixture, the end of the test rope is fixed to the base through the pin instead of being fixed to the winding wheel, so that stress is more scientific; besides, the fixture can be miniaturized.

Description

technical field [0001] The invention relates to the technical field of mechanical property detection and test equipment, in particular to a safety rope fracture strength detection fixture and a testing machine. Background technique [0002] The breaking strength of the safety rope (safety flat (vertical) net, safety belt) is an important index to measure its safety, which directly affects the bearing capacity of the safety rope and the life safety of the construction personnel, so it must be tested for its breaking strength performance. For a long time, wedge-shaped fixtures and pin-fixed eye-ring fixtures are mainly used to test on the testing machine. The clamping part of the wedge-shaped fixture test device to detect the sample needs to be reinforced, and often slips or the sample breaks outside the marked range, resulting in test results. If it is invalid, the sample production of the pin-fixed eye ring fixture test requires the assistance of the manufacturer, which is n...
