为确保煤矿职工的健康及提高煤矿安全水平,安全规程规定:垂深超过50米的上下人员的主要斜巷,都必须采用机械运送人员,并设置在人车运行中随时能与绞车司机进行信号联系的可靠装置。由于井下环境条件很差,现行的斜井人车信号在适用性,可靠性方面都存在一些问题,本文通过对几种人车信号的逐一分析,提出一种新的低压触线式斜井人车信号。 一、几种人车信号系统的分析 1.我矿东风井斜井信号原设计的电气原理图(图1),人车信号部分是由一般煤位信号晶体管继电器改制而成,用转换开关
In order to ensure the health of coal mine workers and improve the safety level of coal mines, the safety regulations stipulate that the main inclined roadway for the ascending and descending personnel with a depth of more than 50 meters must be transported by mechanical personnel and be set to signal the winch drivers at any time during the operation of the vehicle Contact the reliable device. Due to the poor underground environmental conditions, the current inclinometer signals have some problems in applicability and reliability. In this paper, by analyzing the signals of several types of vehicles and vehicles, a new type of low-voltage inclinometer Car signal First, the analysis of several kinds of people and vehicles signal system 1. I mine mine shaft incision signal original design of the electrical schematic (Figure 1), the signal part of the car by the general coal level signal transistor relay restructuring, with the transfer switch
