Problems solved by technology

[0003] For the coal mine field, the mechanical performance requirements of the belt 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 mining belt.

Embodiment 1

[0031] Embodiment one: see figure 1 , figure 2 , image 3 . A full-width belt stretching fixture, vertically fixing two vertical plates 1 on the bottom plate, the outer surfaces of the two vertical plates 1 are not limited but the inner surfaces are inclined and symmetrical, and the angle between the inner surfaces of the two vertical plates 1 is α, And 13°≤α≤23°.

[0032] Two symmetrical wedge-shaped slide plates 2 are respectively matched and attached to the inner surfaces of the two vertical plates 1, so that the angle between the outer surfaces of the two wedge-shaped slide plates 2 is also α, and 13°≤α≤23°. The inner surfaces of the two wedge-shaped slide plates 2 are parallel to each other.

[0033] The inner surface of each wedge-shaped sliding plate 2 and the clamping block 3 are connected together through a vertically arranged dovetail groove and a dovetail strip 31 matching structure. The inner surface of the clamping block 3 is a friction surface 32 with reti...

Embodiment 2

[0035] Embodiment two: see figure 1 , figure 2 , image 3 . A full-width belt stretching jig, the jig is the same as the first embodiment, and will not be repeated, the difference is that the angle between the inner surfaces of the two vertical plates 1 is α, and 15°≤α≤20°. Therefore, the angle between the outer surfaces of the two wedge-shaped slide plates 2 is also α, and 15°≤α≤20°. The range of the width L of the rubbing surface 31 is 300mm, or 340mm, or 350mm, etc.

Embodiment 3

[0036] Embodiment three: accompanying drawing is not drawn. A fixed-installed full-width belt tensile jig, the jig is the same as in Embodiment 1, and will not be repeated, the difference is that the two vertical plates 1 are directly fixed on the base plate 4 of the tensile testing machine.

Abstract

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 a, and 13° = a = 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.

Description

technical field [0001] The invention relates to the technical field of a mining integral belt testing equipment, in particular to a full-width belt tensile fixture and a horizontal belt 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. Existing clamps have the following disadvantages: [0003] For the coal mine field, the mechanical performance requirements of the belt 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 mining belt. . Contents of the invention [0004] Aiming at the deficiencies in the prior art, the object of...
