慢动卷扬机的井下安装主要包括两部分,一是卷筒和电器等的机座安装,一是天轮安装。前者比较简单,只需在基岩上打一些锚杆眼,插入锚杆并注浆,待砂浆凝固达到要求时,将锚杆与机座连接即可。后者比较复杂,它有多种形式,要求我们从实际出发,因地置宜,兴利除弊,以达预期的效果。 1.钢井架安装天轮如图1所示,这种方法是将矩形天轮支架焊接在5米高(这个高度主要根据通过井口的设备和自制罐笼等的要求确定)左右的凳子形钢井架上。在地表这种方法应用比较普遍,而在井下一般只用在岩石结构不太
Downhole installation of slow winch mainly includes two parts, one is the base of the drum and electrical installation, the installation of the day wheel. The former is relatively simple, just hit the bedrock anchor bolt, insert bolt and grouting, mortar to be solidified to meet the requirements, the bolt can be connected with the base. The latter is more complex, it has many forms, requires us to proceed from reality, due to the location, interest and disadvantages, in order to achieve the desired results. 1. Steel derrick installation Celestial wheel as shown in Figure 1, this method is the rectangular day wheel bracket welded to 5 meters high (mainly based on the height of the wellhead through the equipment and homemade cage and other requirements to determine) around the stool steel derrick on. The application of this method in the surface is more common, but generally only used in the underground rock structure is not too
