A steel wire rope tensile grip and a horizontal steel wire rope tensile tester machine thereof. The steel wire rope grip comprises a symmetrically arranged frame, a wedge-shaped slide, and a friction block (3). The frame comprises two upright plates (1) arranged such that inner surfaces thereof have therebetween an angle, α. An inclination angle of the wedge-shaped slide (2) matches α of the grip. An inner surface of the wedge-shaped slide (2) and the friction block (3) are connected therebetween by a dovetail groove structure. For angle α, 13°≤α≤23°. The width, L, of the friction block (3) is between 190 mm to 340 mm. The horizontal steel wire rope tensile tester machine comprises in a horizontal arrangement a pressure sensor (8), a power apparatus (6), and, comprising the grip, a fixed steel wire rope tensile grip and a mobile steel wire rope tensile grip. The power apparatus (6) and the mobile steel wire rope tensile grip are connected therebetween by a pull rod (5). The present invention is structurally simple and convenient to operate, requiring only for the machine to be fixed on the ground to allow one person to complete operations of the entire testing process, thereby reducing greatly the amount of labor of testing. Compared to existing tester machines, the machine allows for an energy-saving testing process, is safe, environmentally friendly, movable, and has both low manufacturing costs and testing costs.

Abrégé

A hydraulic horizontal steel wire rope bending fatigue tester machine and an annular composite pad. A base (1) of the fatigue tester machine has fixedly arranged at one end a driving wheel (3), and movably arranged at the other end a testing wheel (5). A rotating shaft of the driving wheel is connected to an output shaft of a retraction driver apparatus via a shaft coupler (14). An input shaft of the retraction driver apparatus is connected to a power machine. The power machine also has connected thereto a photoelectric counter and an electrical control box (9). The machine matches polyester friction pads on the basis of rope diameter to perform bending fatigue tests on steel wire ropes of different diameters, the arc radius of the polyester friction pads matches the sectional radius of the steel wire rope being tested, and allows, on the basis of need, at will removal and installation from a noose of the driving wheel and of the testing wheel. A set load of the machine is implemented via a power apparatus, a pressure sensor, and a spring among other framework structures, departing from the unwieldy method of hanging weights for load employed by other similar apparatus.

Abrégé

Disclosed are a whole width belt tensile fixture and a horizontal belt tensile testing machine containing the fixture. The fixture comprises a bracket, wedge-shaped slide plates (2) and holding blocks (3); the bracket comprises two vertical plates (1) fixed perpendicular to the bottom plate, with the angle between the inner surface of the two vertical plates being α, and 13° ≤ α ≤ 23°; the two symmetrical wedge-shaped slide plates (2) are respectively mated with the inner surface of the two vertical plates, with the inner surface of the two wedge-shaped slide plates being parallel to each other; the inner surface of wedge-shaped slide plate and the holding block (3) are connected together via a dovetail slot and a dovetail strip; each inner surface of the holding blocks has a friction surface with net-shaped friction grain, a belt is clamped between the two holding blocks, the width of the belt is equivalent to the height of the friction surface, and the range of the width of the friction surface L is 240mm to 410mm. The testing machine has a simple structure and easy operation. It only needs to be fixed on the ground, and one person is able to complete the operation of the entire test process, which enables the amount of labour for a detection test to be reduced significantly. In addition, it has the advantages of energy-saving, environment protection, safety and mobility, and low production and experimentation costs.
