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 an automatic hitting device for a soft coal Oya expansion meter. The automatic hitting device comprises a shaping hitting device, a fixed bottom plate, right-angle pieces, an automatic lifting device and an automatic hitting rod replacing device; the automatic lifting device and the automatic hitting rod replacing device are vertically and fixedly arranged on the fixed bottom plate through the right-angle pieces correspondingly, and the shaping hitting device is fixed to the fixed bottom plate; and the automatic lifting device is used for pulling up a hammer block on the shaping hitting device, and the automatic hitting rod replacing device is used for replacing a hitting rod and fixing the position of the hitting rod. The automatic lifting device of the automatic hitting device is driven by a driving device, the driving device drives a lead screw to rotate and drives up-down movement of a fixed platform, thus the hammer block is automatically lifted and falls,it is ensured that the lifting height of the hammer block is stable, the automation degree is high, operation is easy, and the data error is lowered.

Description

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