Problems solved by technology

Based on the experimental standard of coal Aoya dilatometer (GB5450-85), if the number of strikes is not enough or the hammer block of the forming striker is not stretched to a height of 505mm and falls, it will affect the experimental data; and so repeatedly during the test Pull the hammer to the highest point, and repeatedly tighten and loosen the rope on the pulley. This operation is cumbersome, inconvenient, and prone to data errors

Abstract

The invention discloses a bituminous coal Oya dilatometer automatic striking device. The device comprises a forming striker, a fixed bottom plate, a right-angle part, an automatic lifting device and astriking rod automatic changing device; the automatic lifting device and the striking rod automatic changing device are fixedly arranged on the fixed bottom plate through the right-angle part; the forming striker is fixed on the fixed bottom plate; the automatic lifting device is used for pulling up a hammer block on the forming striker; the striking rod automatic changing device is used for changing a striking rod and fixing a location of the striking rod. The automatic lifting device is driven through the driving device, so that the driving device drives a lead screw to rotate and drives afixed plate to move up and down, thereby realizing the automatic lifting and falling of the hammer block, the lifting height of the hammer block is stable, the automation degree is high, the operationis simple, and the data error is reduced.

Description

technical field [0001] The invention relates to the field of bituminous coal detection equipment, in particular to an automatic striking device for a bituminous coal Aoya dilatometer. Background technique [0002] The degree of expansion of bituminous coal is an important performance parameter in the analysis of coal quality of bituminous coal, and the degree of expansion of coal is widely used in the study of coal coking mechanism, coal quality identification and coal classification, guidance of coking coal and coke strength prediction, etc. . It is recorded in GB5450-85 "Bituminous Coal Aurora Dilatometer Test" that when performing Aurya expansion analysis on bituminous coal, the most important thing is to make a shaped coal pen first. The preparation process of the coal pen is as follows: Weigh 4g of the prepared sample, put In a small evaporating dish, lubricate the sample with 0.4ml of water, mix quickly, and prevent the existence of air bubbles, then place the small-d...
