Translated fromChinese技术领域technical field
本发明涉及带式输送机技术领域，尤其涉及一种煤矿带式输送机集中自动润滑装置。The invention relates to the technical field of belt conveyors, in particular to a centralized automatic lubricating device for belt conveyors in coal mines.
背景技术Background technique
针对井下皮带机滚筒的轴承润滑，目前主要是靠人工定期的加注润滑脂来实现轴承的润滑，由此带来的问题有：每次加注润滑脂，为了保险起见也是加注的标准指标，将润滑脂加注到轴承室中直至新的干净润滑脂溢出为止。由此带来的负面影响有两个：一个是每次加注的润滑脂均超量，造成润滑脂的巨大浪费，也给环境带来巨大的污染；加注的过量的润滑脂阻碍了轴承内部滚动体和保持架的运动-轴承当中，滚动体和保持架也有速度的概念-导致和润滑脂过度摩擦生热，影响了散热造成轴承的温度升高。手动加注润滑脂过程中，由于井下的环境的实际情况和粉尘工况，极易造成润滑脂的污染，导致粉尘颗粒进入到轴承室中，对轴承造成提前失效。据理论计算，大约有56％的轴承失效是因为润滑油污染造成的。井下皮带机部位，空间局促，皮带运转时危险性较大。对维保人员的要求相对比较高。若思想松懈，极易造成人员的伤害。人工加注油脂的不及时也会造成轴承的寿命缩短导致轴承提前失效。For the bearing lubrication of the pulley of the underground belt conveyor, at present, the lubrication of the bearing is mainly achieved by manual and regular filling of grease. The problems caused by this are: every time the grease is added, it is also a standard indicator for filling for the sake of safety. , fill the bearing chamber with grease until new clean grease overflows. There are two negative effects brought about by this: one is that the amount of lubricating grease added each time is excessive, resulting in a huge waste of lubricating grease, and also brings huge pollution to the environment; the excessive amount of lubricating grease added hinders the bearing The movement of the internal rolling elements and the cage - among the bearings, the rolling elements and the cage also have the concept of speed - leads to excessive friction and heat generation with the grease, which affects the heat dissipation and causes the temperature of the bearing to rise. During the manual grease filling process, due to the actual conditions of the downhole environment and dust conditions, it is very easy to cause grease pollution, causing dust particles to enter the bearing chamber, causing early failure of the bearing. According to theoretical calculations, about 56% of bearing failures are caused by lubricating oil pollution. The space of the underground belt conveyor is cramped, and the belt is more dangerous when it is running. The requirements for maintenance personnel are relatively high. If the thinking is lax, it is very easy to cause personal injury. Untimely manual grease filling will also shorten the life of the bearing and lead to premature failure of the bearing.
综上，现有技术中仍缺少一种能够根据带式输送机的输送速度精准和轴承温度进行润滑工作，并实时调整润滑速度，提高加注效率的自动润滑装置。To sum up, the prior art still lacks an automatic lubricating device capable of lubricating according to the precise conveying speed and bearing temperature of the belt conveyor, adjusting the lubricating speed in real time, and improving the filling efficiency.
