Bridge-type intelligentized car coal sampling machine and sampling method thereof

Abstract

The invention discloses a bridge-type intelligentized car coal sampling machine. The bridge-type intelligentized car coal sampling machine comprises a steel structure room, a cart mechanism, a trolley mechanism, a sampling head, a belt feeder, a crusher, a divider and a sample collector, wherein the upper part of the steel structure room is provided with a crane beam; the crane beam is provided with a track; the cart mechanism is connected to the track in a sliding mode; the trolley mechanism is connected to the cart mechanism in a sliding mode; the sampling head is installed on the trolley mechanism which is provided with a hydraulic lifting system controlling the sampling head to lift; the sampling head is a full-fracture sampling head; the steel structure room is also internally provided with an operation room which is internally provided with a display, an industrial control machine, a PLC cabinet and a power cabinet; the steel structure room is also internally provided with a monitoring device and a wireless radio frequency recognition device; the top of the steel structure room is provided with a photographing and positioning device and an illumination device. The bridge-type intelligentized car coal sampling machine can sample a full fracture, is high in sampling precision, and can sample automatically, thus cheat brought by artificial sampling is eliminated, and the sampling process is rapid.

Description

technical field [0001] The invention relates to a coal mining prototype, in particular to a bridge-type intelligent vehicle coal mining prototype and a sampling method thereof. Background technique [0002] Fuel coal sampling was originally done manually. Due to human factors, sampling is not representative, and manual sampling is very unsafe, labor-intensive and time-consuming, and cannot meet the needs and management requirements of bulk material logistics development. [0003] The development of mechanized sampling machines has gradually replaced manual sampling. Mechanized sampling has reduced the labor intensity and working environment of workers, but it has not yet solved the human operation factor, and has not fundamentally eliminated the risk factors that cause economic losses. [0004] The original car sampling machines are mainly swing arm type, cantilever type and bridge type manual spot sampling. [0005] Swing arm car sampling machine is mainly composed of samp...

Problems solved by technology

[0027] The invention adopts a bridge structure, and the cart walks on the crane beam, which solves the shortcoming that the sampling machine cannot collect long compartments; the trolley walks on the cart beam, which solves the accuracy of sampling point positioning, and does not require angle conversion; The design of the cross-section sampling head solves the defect of low sampling accuracy when coal sampling is prohibited, and increases the sampling volume to improve the sampling precision; the sampling machine adopts radio frequency card reading technology, and various data are connected to the combustion pipe system without manual input. Sampling records are automatically recorded by the upper computer (computer) to eliminate human factors; the monitoring system is perfect, the chain protection is perfect, and the faults and elimination methods are automatically displayed; the samples are automatically packaged and encrypted, and the sampling and delivery personnel cannot read the sample information, only the identification code, The information is uploaded to the management system, and the senior management personnel with authority can view various sampling and testing data and information; the sampling machine program runs automatically, and the sampling personnel can only have the emergency stop function, and cannot artificially select the sampling point, eliminating human factors and ensuring fairness of sampling
