The invention relates to a roller type crane roll-on roll-off jig frame setting process. The process is characterized by comprising the following specific size control steps: S1, jig frame arrangement; s2, operation before turning over of the rotary chassis; s3, assembling a jig frame on the reaction wheel assembly; s4, assembling a jig frame on the rotary chassis structure; s5, folding and welding the reaction wheel and the rotary chassis; s6, assembling a jig frame on the weight box and grouting; s7, installing a winch base and arranging mechanisms; s8, mounting a slewing mechanism; according to the method, the mounting size precision of each component is controlled from the arrangement of the jig frame of the roller crane, the precision needs to be controlled within a reasonable range in each step, and when the crane rotary structure is finally mounted, the size precision control of the rotary structure is realized; compared with a final detection and installation mode, the installation step of gradually detecting and controlling the precision has the advantages that the assembly efficiency is reduced, but the precision requirement is ensured, so that the probability of reworking and finishing is reduced.
本发明涉及一种滚轮式起重机滚装胎架设置工艺,其特征在于:包括具体尺寸控制如下:S1:胎架布置;S2:回转底盘翻身前操作;S3:反滚轮组件上总装胎架;S4:回转底盘结构上总装胎架;S5:反滚轮与回转底盘合拢焊接;S6:配重箱上总装胎架并灌浆;S7:绞车基座安装和机构排装;S8:回转机构的安装;本发明中从滚轮式起重机的胎架布置开始控制各部件的安装尺寸精度,每一步中均需要将精度控制在合理的范围内,在最终安装起重机回转结构时,实现回转结构的尺寸精度控制;这种逐步检测控制精度的安装步骤,相比于最终进行检测安装的方式,虽然降低了装配效率,但是保证了精度的要求,从而降低了返工修整的概率。
