最近我們在学习关門山自动提引器的基础上,根据前一阶段实践中发现的問題,結合冶金部系統的实际情况新设计一种自动提引器,經过在实际中試驗証明,这种自动提引器不仅具备操作方便、結构簡单、加工容易的特点,同时适用于不同角度的斜孔和包箍鑽杆,提高了升降鑽具的效率,保证了操作安全。一、結构: 自动提引器結构如图1所示。由提引器本体(1),提梁(2),滾輪軸(3),滾輪(4),滾轮挡板(5),开口銷(6),弹簧(7),滾轮轴穿釘(8),挡板
Recently, based on the study of the Guanmenshan Automatic Extractor, based on the problems found in the practice of the previous stage, a new automatic extractor was designed in conjunction with the actual conditions of the Ministry of Metallurgical Department. The automatic feeder not only has the characteristics of convenient operation, simple structure and easy processing, but also applies to inclined holes and hoop drill rods in different angles, which improves the efficiency of the lifting drilling tool and ensures the operation safety. First, the structure: Automatic extractor structure shown in Figure 1. Lifter body (1), Lifting beam (2), Roller shaft (3), Roller (4), Roller baffle (5), Cotter pin (6), Spring (7), Roller shaft screw (8) )
