Steel wire rope tensile fixture and horizontal steel wire rope tensile testing machine thereof

Abstract

The invention discloses a steel wire rope tensile fixture and a horizontal steel wire rope tensile testing machine thereof. The steel wire rope tensile fixture comprises frame bodies, wedged sliding plates and friction blocks which are arranged symmetrically, wherein each frame body comprises two vertical plates of which the inner surfaces are arranged by forming an included angle alpha; the inclination angle of each wedged sliding plate is matched with the included angle alpha; the inner surface of each wedge sliding plate is connected with each friction block through a vertical dovetail groove structure; the included angle alpha is more than or equal to 13 degrees and less than or equal to 23 degrees; and the width L of each friction block is 190-340 millimeters. The horizontal steel wire rope tensile testing machine comprises a pressure sensor, a power device, a fixed steel wire rope tensile fixture and a movable steel wire rope tensile fixture, wherein the pressure sensor is arranged horizontally; the fixed steel wire rope tensile fixture comprises an upper fixture; and the power device is connected with the movable steel wire rope tensile fixture through a pull rod. The horizontal steel wire rope tensile testing machine has a simple structure, and is convenient to operate; the horizontal steel wire rope tensile testing machine is only required to be fixed on the ground, and the operation of the entire test process can be completed by one person, so that the labor intensity of detection test can be reduced greatly; and compared with the conventional testing machine, the horizontal steel wire rope tensile testing machine has the advantages of energy-saving test process, safety, environmental friendliness, mobility, low manufacturing cost and low test cost.

Description

technical field [0001] The invention relates to the technical field of mine steel wire rope testing equipment, in particular to a steel wire rope tensile fixture and a horizontal steel wire rope tensile testing machine. Background technique [0002] In the field of material tensile testing, the sample must be reliably clamped to prevent slipping, so that the technical parameters such as tensile strength, yield strength, elongation, residual stress, and elastic modulus of the material can be accurately obtained. [0003] For the coal mine field, the mechanical performance requirements of the steel wire rope are relatively high, and the existing testing machine is difficult to cope with it. Due to its own design defects, the existing testing machine basically cannot do the breaking test and cannot complete the complete inspection of the mine steel wire rope. . [0004] For the mining field, as the mine goes deeper, the diameter of the hoisting wire rope used is getting th...

Problems solved by technology

From the perspective of energy saving, safety, and environmental protection, the traditional casting method breaks the mine wire rope, and the molten metal wastes a lot of electric energy, causing many unsafe hidden dangers during casting; molten metals such as lead and zinc are harmful to the human body and are not environmentally friendly. It is not high. Before casting, the two ends of the tested steel wire rope are split, broken up, and bent. It takes a lot of time. The breaking stretch is not only expensive. Larger, it is difficult to guarantee the accuracy requirements
