1971年我国从西德引进了3米、3.5米单绳缠绕式绞车23台,其中10台分配在冶金系统,13台分配在煤炭系统,作为建井时提升运输用。煤炭系统比冶金系统使用较早。安装操作维护经验亦比较丰富。所以,我们于1979年7月间对煤炭系统的兖州、淮北、邯郸、开滦四矿共9台引进绞车进行了调查。调查结果表明,与国产绞车相比,西德绞车有不少特点。本文从几个方面对其基本特点予以介绍。安全性能 1.闸控制系统制动闸为气动瓦块绞型抱闸,与国产仿苏绞车相似,但控制系统无级可调,轻便可靠,远较仿苏设备为好。其主要控制元件及作用原理如图1。
In 1971, China imported 23 sets of 3-meter and 3.5-meter single rope winches from West Germany, of which 10 were allocated to the metallurgical system and 13 to the coal system for transportation improvement. The coal system is used earlier than the metallurgical system. Installation operation and maintenance experience is also abundant. Therefore, in July 1979, we conducted a survey on the introduction of 9 winches into the four coal mines of Yanzhou, Huaibei, Handan and Kailuan of the coal system. The survey results show that compared with domestic winches, West Germany winch has many features. This article introduces its basic characteristics from several aspects. Safety 1. Brake brake control system for the pneumatic braid brakes, and imitation Soviet winch similar, but the control system stepless adjustable, lightweight and reliable, far better than the imitation of the Soviet Union equipment. The main control components and the role of principle shown in Figure 1.
