长臂挖掘机大小臂开裂的修复方法

日期:2022-05-09   来源:http://www.dyqicheng.com/
  大小臂,作为主要的长臂挖掘机主要的工作部件,起到的作用很大,但问题也存在,比如说开裂,这个时候应该及时进行修复。
  The big arm, as the main working part of the main long arm excavator, plays a great role, but there are also problems, such as cracking, which should be repaired in time at this time.
  大小臂在作业状态基本每个动作都要受力,虽然钢铁冶炼技术在如今已经非常发达,但每个产品都有它的使用寿命,因此在经过一段时间的使用后,长臂挖掘机大小臂都会一定几率出现裂开的情况,只是开裂的情况各有千秋。
  The big and small arms have to be stressed in every action in the working state. Although the iron and steel smelting technology has been very developed now, each product has its service life. Therefore, after a period of use, the big and small arms of the long arm excavator will have a certain chance of cracking, but the cracking situation varies.
  出现开裂问题时,大家一般都会到修理厂进行裂开部分的修复工作,但是,各修理厂师傅技术参差不齐,有些修好能顶住,有些修不好顶不住。其实除了跟本身的技术有关外,更重要的是修复的方案问题。
  When the cracking problem occurs, we generally go to the repair shop for the repair of the cracked part, but the repair shop master technology is uneven, some repair can withstand, some repair can not stand. In fact, in addition to its own technology, more important is the solution of the problem.
  由于断裂的情况不一,但是大小臂都是焊结构件,修补无非都是焊接。如果断裂部分在大臂油缸耳座前面一点,不建议继续工作,防止继续撕裂,产生安全事故。针对这个开裂情况该用何种修复方法?
  Because the fracture situation is different, but the arms are welded structural parts, repair is nothing more than welding. If the broken part is a little in front of the big arm cylinder ear seat, it is not recommended to continue working to prevent further tearing and safety accidents. What kind of repair method should be used for this cracking situation?
  我们应该切割一部分,由断裂处左右各割去侧板180-200,下面的盖板以侧板割去的180-200往左右再多割去约150。接下来,在断裂的盖板下面打好衬板,焊好,盖板裂缝也一并焊好。(如图3)焊接过程应该平整无气泡产生。
  We should cut part of it, and cut the side plates 180-200 from the left and right sides of the fracture, and cut the lower cover plates 180-200 from the side plates and then cut about 150 more from the left and right sides. Next, the lining plate is played under the broken cover plate, and the cracks in the cover plate are also welded. (FIG. 3) The welding process should be smooth and free of bubbles.
  焊好后,根据切去的青色部分侧板,按尺寸重新切割一块铁板焊接上去,且在里面打上衬板。衬板要比封上去的侧板长点。
  After welding, according to the cut cyan part of the side plate, according to the size of a new cut iron plate welding, and in the lining board. The backing plate is longer than the sealing side plate.
  完成这步后,就差底盖板没有封上了,在封底盖板之前,还是先打衬板,为了增加焊接接触面积,巩固焊接的牢固性,打完衬板及封好底板后,修补工作基本完成。接下来可以打磨,补腻子上油漆了。
  After completing this step, the bottom cover plate is not sealed. Before sealing the bottom cover plate, the lining plate is first played. In order to increase the welding contact area and consolidate the welding firmness, the repair work is basically completed after the lining plate and the bottom plate are sealed. Next you can polish and paint the putty.
  长臂挖掘机租赁人员认为修复的关键除了修复方法,焊接技术因素,与焊接采用的气体也有很大关系。一般普通的修理厂都是用普通二氧化气体焊。在这里建议采用二保焊焊接比较好,结实不容易开焊,因为二保焊温度高焊接面积比较大,能使钢板有效的结合。
  Long arm excavator leasing personnel believe that the key to repair in addition to repair method, welding technology factors, and welding gas is also very related. Ordinary repair shops are welded with common dioxide gas. Here it is recommended to use two welding welding is better, strong is not easy to open welding, because two welding temperature is high welding area is larger, can make the steel plate effective combination.
