Mining roller cage shoe strain pressure test bench

Abstract

The present invention discloses a mining roller cage shoe strain pressure test bench. The test bench comprises a foundation slab, wherein a left side of an upper part of the foundation slab is fixed to a first box body, a fixed seat is fixed on the first box body, the fixed seat is provided with an expandable arm, a rotating wheel is disposed on the expandable arm, the rotating wheel is driven torotate by a motor fixed inside the first box body, a right side of the upper part of the foundation slab is provided with a second box body that can rise and fall by using a lifting apparatus, severaltransverse H-shaped slideways are disposed on the second box body, a mining roller cage shoe is fixed in the slideway by using a bolt, a top pressure seat with a top pressure contact is disposed in the slideway and on a right side of the mounting base, an electric push rod base is disposed on a right side wall of the second box body, the electric push rod base is provided with an electric push rod that makes contact with the top pressure contact, and an outer edge of the roller makes contact with an outer edge of the rotating wheel. The foregoing structure can be used for detecting quality and service life of each batch of mining roller cage shoes through experiments.

Description

technical field [0001] The invention relates to a mine-used roller tank lug fatigue pressure test bench. Background technique [0002] At present, the standard "Rectangular Steel Can Road Roller Ears" issued by the State Administration of Work Safety, the standard number is MT236-2011, which specifies the product classification, technical requirements, test methods, inspection rules, signs, transportation and For storage, the roller tank ears that meet this standard include a bottom frame, a swing frame, rollers and buffer devices. The swing frame is connected to the bottom frame through a hinge, and the rollers are connected to the swing frame through a rotating pair. There is a buffer device between the swing frame and the bottom frame. Under the action of the buffer device, the rubber wheel is always close to the steel tank road in the horizontal direction, and has a horizontal thrust on the steel tank road. When the steel tank road is not straight up and down, When ther...

AI Technical Summary

Problems solved by technology

On the one hand, it is used as a guide wheel for the lifting container to run along the tank road, and on the other hand, it can be connected to the lifting container. However, the quality of the roller lug manufacturers currently used is quite different, and the roller lugs produced by various manufacturers are also different. Similarly, good quality has a longer life span, and poor quality is prone to various problems

There is a large difference in service life, and there are potential safety hazards
