Embodiment Construction

[0043] The section adaptive cutting database of the present invention is constructed on the monitoring system to monitor the state parameters and alarm information of the roadheader in real time, and provide the man-machine interface for setting the roadheading section for the operators. The database development software adopts SQL Server 2008 (server version), and stores the operating state parameters, alarm information and roadway section forming control parameters of the roadheader.

[0044] The specific database construction fields cover:

[0045] (1) Status data: Mainly include the current and voltage signals of the roadheader cutting motor; the roadheader's pose parameters (heading angle, left boundary of the car body, right boundary of the car body); cylinder pressure parameters; cylinder stroke parameters.

[0046] (2) Alarm data: Generate an alarm data table for the overload, short circuit, current leakage, and phase failure of the tunneling machine oil pump motor, cutting m...

Abstract

The invention relates to a tunnel self-adaptation cutting system and a self-adaptation remote control method for a roadheader and belongs to the technical field of coal mining equipment application. The method includes building a tunnel cross section self-adaptation cutting database, using a software application system to monitor moving trajectory of the roadheader, and storing poses and operating data of a cutter and the whole roadheader; using a remote monitoring system to display work condition of a tunneling cross section in real time, and combining with a PLC (programmable logic unit) of the field roadheader to finish remoter wired control of tunnel self-adaptation cutting operations. The poses of the cutter and the whole roadheader can be displayed in real time, adjusting of poses of the whole roadheader and cross section circulating cutting are finished automatically, tunneling efficiency is high, and reliability is high. By remoter control of cross section cutting by the roadheader, an operator is far away from a dangerous sectional operation environment, working environments for the operator is improved, injury accidents of the operator is reduced, and safety is high.

Description

Technical field: [0001] The invention relates to a roadway adaptive cutting system and an adaptive remote control method of a roadheader, belonging to the technical field of coal mining equipment application. Background technique: [0002] The tunneling working environment of the roadheader is harsh, with large dust, insufficient lighting, and high gas concentration. In the traditional manual tunneling mode, the operator's tunneling efficiency is low, the labor intensity is high, and there is a certain degree of danger. For a long time, the safety of tunneling machine operation and tunneling efficiency have always been the focus of the industry. Therefore, it is necessary to provide a roadway section self-adaptive cutting remote control method to overcome the above shortcomings, remotely operate the roadheader to improve the driving efficiency, improve the labor hygiene environment of the operators, and reduce the injury accidents. Summary of the invention: [0003] The purpose o...
