一、結構这种活动工作台是江苏省地质局試驗站机設計制造的。它以钻杆作导軌,使滾輪在导軌上滾动,实現活动工作台的升降运动。其結构如图1所示。导向钻杆1,共有三根:两根在下,一根在上,使滾輪2分别在三根导向钻杆上滾动(图2)。为使工作台能在所需高度上固定,設有鎖卡4。鎖卡是用螺杆旋紧在导向钻杆上做成的。 First, the structure This activity table is designed and manufactured by Jiangsu Provincial Bureau of Geology Experimental Station. It uses the drill rod as the guide rail to make the roller roll on the guide rail to realize the lifting movement of the movable workbench. The structure shown in Figure 1. Guided drill pipe 1, a total of three: two in the next, one on the roller 2, respectively, in three guided drill pipe rolling (Figure 2). In order to make the worktable can be fixed at the required height, a lock 4 is provided. Lock the card is screwed on the guide drill rod made of.
