Multifunctional intrinsic safety type miner lamp applied to underground hydraulic support

Abstract

The invention discloses a multifunctional intrinsic safety type miner lamp applied to an underground hydraulic support and belongs to the technical field of intrinsic safety type miner lamps of underground hydraulic supports. A technical problem to be solved is to provide the improvement of the hardware structure of the multifunctional intrinsic safety type miner lamp applied to the underground hydraulic support. A lampshade is movably installed at the bottom of a miner lamp shell through a first screw, a plug seat is arranged at the top of the miner lamp shell, a fixing plate is movably installed at the top of the plug seat through a second screw, hanging blocks are welded to the two ends of the fixing plate, and screw holes are formed in the hanging blocks; the mine lamp shell is fixed on the top beam of the hydraulic support by the hanging block through a bolt; a control circuit board is installed in the miner lamp shell through a first isolation column, the first isolation column fixes the control circuit board through a third screw, and the control circuit board fixes an illuminating lamp panel to the outer side of the bottom of the miner lamp shell through a second isolation column. The device is installed and applied to the underground hydraulic support.

Problems solved by technology

[0002] In terms of signal indication and lighting in coal mines, mine intrinsically safe lamps play an important role. This type of miner's lamp is required to be suitable for explosive environments such as gas and coal dust; currently, intrinsically safe miner's lamps mostly use LED light source lamps Design, low power consumption, high safety, high brightness, long life, with the function of prompting the locomotive ahead, pay attention to safety, warning pedestrians or passing vehicles, etc., can effectively avoid the occurrence of underground accidents; and the existing LED intrinsically safe type When the miner's lamp is used for the indicator light controlled by the hydraulic support, it can no longer meet the needs of its underground operations. The main defects are:

[0003] 1. When the coal mine industry chooses mining lights, most of them are limited to single-function lights, which cannot show variable indication states. Lighting lights and warning lights are often independent individuals. If you need to set variable alarm signs, Stable lighting sources may require extra financial and manpower to customize. The existing signal lights always flash with a fixed color at one frequency, and have a single function, which cannot reflect the changeable attitude status of the hydraulic support controller;

[0004] 2. The personnel in the underground working face need lights with sufficient brightness for equipment maintenance, and a single signal light cannot provide an effective light source;

[0005] 3. The signal lights traditionally used for hydraulic support controllers are only passively controlled by the controller, and cannot automatically sense whether there is equipment or personnel entering;

[0006] 4. This type of miner's lamp needs to be connected to a separate power supply device. In a narrow space, if additional equipment is added, the installation will be very inconvenient and time-consuming.
