我队改制自动提引器在某千米钻孔试用成功.它能减少操作人员,避免塔上高空作业及减轻体力劳动.其构造和使用分两部份:一、上升提引器的构造及操作上升提引器的构造如图1所示,是由外壳⑤、两组活动(凸出)抱瓦⑧、弹簧⑩、滑动揣圈⑦以及滑动扁铁⑥和提引轴①等所构成.为支持抱瓦活动,外壳下部有法蓝盘和固定螺钉;为便利提引器正常工作,在每个立根上接一提引卡头,如图2所示,其长为130公厘.最大直径为90公厘,最小直径为70公厘.装配 My team restructuring automatic lifting device in a kilometer drilling trial success.It can reduce the operator, to avoid the tower at high altitude and reduce manual labor.Its construction and use of two parts: First, the structure of lifting device and The structure of the operating riser is shown in Fig.1. The housing is composed of a housing (5), two movable (protruding) covers (8), a spring (10), a sliding collar (7), a sliding flat iron (6) and a lift shaft (1). In order to support the tile activity, the lower part of the shell has a blue plate and a fixing screw; in order to facilitate the normal operation of the lifter, a snap chuck is attached on each vertical root, which is 130 mm long as shown in Figure 2. The maximum Diameter of 90 mm, minimum diameter of 70 mm. Assembly
