Safety interlocking control system for crane position loading

Abstract

The invention relates to a safety interlocking control system for crane positioning loading. The safety interlocking control system comprises a human body electrostatic elimination module for realizing safety discharge of static electricity of a human body, a vehicle electrostatic elimination module for realizing safety discharge of static electricity of a vehicle, a crane pipe homing detection module for detecting a crane pipe position, an oil overflow alarm module for detecting the liquid level of an oil product, a control module for receiving signals from all the modules and making judgment processing on the signals and an actuating mechanism which is controlled by the control module and is used for controlling whether to carry out an oil filling operation. The safety interlocking control system is applicable to oil distribution crane positions of all gasoline and diesel oil in the petrochemical industry; a large number of electrostatic charges carried by a driver and the vehicle are eliminated through eliminating the static electricity of the human body and eliminating the static electricity of the vehicle, and thus a great potential safety hazard in the whole oil distribution process is eliminated. Pollution and waste caused by overflowing of the oil product are avoided through crane pipe homing detection and oil overflow alarm detection.

Description

technical field [0001] The invention relates to a safety interlock control system, in particular to a safety interlock control system for crane loading of oil and chemical products. Background technique [0002] When the company's vehicles are loaded with oil at the loading crane, most drivers wear chemical fiber clothes that are prone to electrostatic charge, and the vehicle is running at high speed on the road. When filling gasoline, diesel or liquefied petroleum gas, if the accumulated large amount of electrostatic charge is not removed in time, if the concentration of combustible gas on the scene is high when the driver performs fuel delivery operation at the loading crane position, the electrostatic charge generated by the driver or the vehicle will not be released. Eliminate, cause very big potential safety hazard to whole filling oil process. In addition, when the crane tube deviates from the normal working position or cannot be found in time after filling up, seriou...
