Operation board control device capable of achieving automatic power off

Abstract

The invention relates to an operation board control device capable of achieving automatic power off. The operation board control device comprises a box body, card plug-in cases, an operation board and outer interfaces. A plurality of card plug-in cases are arranged on the front side of the box body, each card plug-in case is provided with a plurality of plug-in slots, and the back side of the box body is provided with a plurality of outer interfaces corresponding to the card plug-in cases on the front side. A plurality of powering-off devices are connected in series and connected with the outer interfaces. A sliding mechanism comprises a horizontal slide block, a horizontal slide way, a horizontal cushion block, a longitudinal slide way, a longitudinal cushion block, a connecting rod, spring pads and a push rod. The horizontal cushion block with the spring pad and the horizontal slide block are arranged in the horizontal slide way in sequence, the longitudinal cushion block with the spring pad and the push rod are arranged in the longitudinal slide way in sequence, and two ends of the connecting rod are respectively and movably connected with the horizontal slide block and the push rod. The operation board control device has the advantages of achieving the automatic power off without the operation board, fundamentally achieving the possibility that the device can not be operated again without the operation board and reducing the possibility of safety accidents caused by errors.

Description

technical field [0001] The invention relates to a safety control device, in particular to an operation card control device capable of realizing automatic power-off. Background technique [0002] The "Safety Sign Operation Card Management Rules" stipulates that the operation card is a mechanical (such as lifting, pressure, heat treatment, shearing, conveyor belt (beam, chain), hydraulic, welding, packaging, etc.) equipment operation, maintenance, etc. A unique credential that a device has control over. In the maintenance operation, the principle of "whoever operates, who holds the license" must be adhered to, and the separation of people and licenses is strictly prohibited (excluding one license for multiple purposes); the operation license is for the post and maintenance personnel to perform equipment operation or maintenance, and check personnel to enter the equipment The only work certificate for maintenance, point inspection and other operations in the operating area.

[0003] At present, it is placed in the form of a visual board and regulated in the form of a system. Only licensed personnel can operate equipment. This method cannot completely restrain the behavior of staff, that is, once someone does not understand the system, they will operate without a license , endangering personal safety

[0004] Under the current background, only the system stipulates that the operation license must be held to have the authority to operate the equipment, and the phenomenon of "unlicensed operation" cannot be completely eliminated, that is, it can only be avoided by relying on people's compliance with rules and regulations. The occurrence of an accident poses a great safety hazard
