我单位1台卡特彼勒844H型轮胎式推土机,因推土铲动臂产生严重弯曲变形,无法正常工作。该机工作质量为70815kg,总功率为512kW,推土铲土方容量为15.9~30.7m~3。为了恢复该机性能,我们根据动臂损坏的具体情况,制定出一套切实可行的修复工艺,并圆满完成修复工作。1.动臂变形原因该机推士铲两侧动臂弯曲变形情况如图1所示。推土铲动臂弯曲变形的直接原因是石块卡滞,间接原因是
A Caterpillar 844H wheel-type bulldozer for my unit caused serious bending deformation of the dozer blade and failed to work properly. The working quality of the machine is 70815kg, the total power is 512kW, the earthwork capacity of the bulldozer is 15.9 ~ 30.7m ~ 3. In order to restore the aircraft performance, according to the specific circumstances of boom damage, we developed a set of feasible repair process and successfully completed the repair work. 1. Boom deformation reasons Boom shovel on both sides of the arm bending deformation shown in Figure 1. Bulldozer boom bending deformation is the direct cause of rock block, the indirect reason is
