Mine diesel locomotive protection monitoring meter mainframe

Abstract

The invention discloses a mine diesel locomotive protection monitoring meter mainframe, and relates to the technical field of coal mine equipment. The mine diesel locomotive protection monitoring meter mainframe comprises a mainframe body and a plurality of interfaces arranged on the mainframe body, and a connecting plate for fixing the mainframe body on a diesel locomotive is arranged on one sideof the mainframe body, and the connecting plate and the side wall of the diesel locomotive are fixedly connected through a connecting mechanism. The mine diesel locomotive protection monitoring metermainframe can monitor driving parameters such as the exhaust temperature and the rotating speed of the diesel locomotive, provides a sound and light alarm function when the relevant parameters exceedthe allowable range, and can connect the switch quantity output of the monitoring meter to an electromagnetic valve on a diesel locomotive oil way, and opening and closing of the electromagnetic valve are accordingly controlled; and when the concentration of methane in wind flow in a monitored area reaches a preset power-off point or when a sensor happens faults such as power or signal line opencircuits and short circuits to enable a methane concentration signal value of a power breaker to exceed the measurement range, the monitoring meter mainframe is locked.

Description

technical field [0001] The invention relates to the technical field of coal mine equipment, in particular to a host of a mine diesel locomotive protection monitor. Background technique [0002] Mining electric locomotives are mainly used for long-distance transportation in underground transportation lanes and on the ground. It is equivalent to the electric locomotive in railway transportation. It pulls a train composed of mine cars or people's cars on the track, and the electric locomotive that completes the transportation of coal, gangue, materials, equipment, and personnel is called a mining electric locomotive. [0003] Mining electric locomotives are composed of mechanical parts and electrical parts. The mechanical part includes: frame, wheel set, bearing box, spring bracket, brake device, sand spreading device, connection buffer device, etc. The electrical part includes DC series motor, controller, resistance box, pantograph, air automatic switch or flameproof plug, b...

AI Technical Summary

Problems solved by technology

[0006] Among them, the camera monitor is disclosed. Although this vehicle-mounted coal mine underground environmental warning device can be used in conjunction with mine electric locomotives, the detection of temperature, humidity and methane concentration is accurate, and the video monitoring is clear, which can realize all-round real-time monitoring of transportation roadways. environment, but it cannot monitor parameters such as exhaust temperature and rotational speed on the diesel locomotive. At the same time, if the diesel locomotive fails, the monitor host on it can only be idle or repaired together with the diesel locomotive. This is a waste of resources for the monitor host ; And the monitor host is fixed on the diesel locomotive, once the monitor breaks down, its disassembly and maintenance are inconvenient, and the overall maintenance process consumes a long time
