Title:
PROTECTION DEVICE FOR TELESCOPIC COLD CUTTING MACHINE FOR COAL MINE, AND METHOD OF USE
Document Type and Number:
WIPO Patent Application WO/2023/115867
Kind Code:
A1
Abstract:
A protection device for a telescopic cold cutting machine for a coal mine, and a method of use. The protection device comprises a handheld device and a protection support (1), wherein the protection support (1) is internally provided with a pressure sensor (2) and an infrared sensor (4); and the protection support (1) is mounted in front of a spray head (7) of a cold cutting machine. The protection device further comprises a first single-chip microcomputer (20), a second single-chip microcomputer (30) and a main controller (40), wherein an input interface of the first single-chip microcomputer (20) is connected to the pressure sensor (2), and an output interface of the first single-chip microcomputer (20) is connected to the main controller (40); and an input interface of the second single-chip microcomputer (30) is connected to the infrared sensor (4), and an output interface of the second single-chip microcomputer (30) is connected to the main controller (40). Firstly, the application range can be expanded by extending and shortening a handheld telescopic rod (6); secondly, a position in front of the spray head (7) is effectively protected by means of a top plate (12), so that casualties can be avoided; and finally, the infrared sensor (4) and the pressure sensor (2) are combined to achieve the automatic stopping of cutting, thereby achieving dual protection of a cold cutting device.
