介绍了新研制的TJ41-SY井架底座设计要求与结构特点。该型井架底座的现场拖运试验分为五个步骤进行:第一,用一部上海120拖拉机强拖试验;第二,用四部拖拉机挂接井架底座中部拖运试验;第三,用四部拖拉机强行牵引井架底座的一侧拖运试验;第四,用十四部拖拉机进行整体拖运试验;第五,底座原地拖动旋转180度试验。试验结果均未发现联接部位松动和底座变形等现象。 Introduced the newly developed TJ41-SY derrick base design requirements and structural features. The on-site haulage test of the derrick base is divided into five steps: first, a strong drag test is carried out on a Shanghai 120 tractor; secondly, four tractors are used to haul the middle haulage test on the derrick base; thirdly, four tractors Forced traction derrick base side of the haulage test; Fourth, with 14 tractors for the overall haulage test; Fifth, the base in situ drag rotation 180 degrees test. The test results did not find the joints loose and the base deformation and so on.
