挖掘机加长臂内部缓冲板起到的作用是什么?

加长臂挖掘机通过先进的电脑辅助设计系统,各类加工设备,熟练员工技能和实际应用知识和经验,从应力分析、材质选择、技术和工艺、设计制作等方面保证了挖掘机加长大小臂的结构强度、使用性能和质量。挖掘机加长臂内安装有内部缓冲板以承受张力负载,延长了挖掘机加长大小臂、挖掘机加长臂的使用寿命。
Through the advanced computer aided design system, all kinds of processing equipment, skilled staff skills and practical application knowledge and experience, the long arm excavator ensures the structural strength, service performance and quality of the added long arm from stress analysis, material selection, technology and technology, design and production, etc. An internal buffer plate is installed in the extension arm of the excavator to bear the tension load, which prolongs the service life of the extension arm and the extension arm of the excavator.
如果以上3项检查全部正常,检查钢绳伸缩系统,拆去伸臂和缩臂拉索,单独靠伸缩缸带动伸缩臂,若伸缩臂伸缩自由且无抖动或响声,当装上伸臂和缩臂拉索后再次试验伸缩时,如果伸臂出现抖动或发出响声,则原因可能出在钢绳伸缩系统。平衡阀有故障或油管中有空气也是伸臂不能回缩的主要原因,如果因进油管产生泄漏而进气,可先排除泄漏,然后反复拉推操纵杆,使气体沿回油路回油箱;若平衡阀有故障,
If all the above three checks are normal, finally check the steel cable expansion system, remove the boom extension and boom retraction cables, and drive the boom by the expansion cylinder alone. If the boom expansion is free and there is no shaking or noise, when the boom extension and boom retraction cables are installed and tested for expansion again, if there is shaking or noise in the boom extension, the reason may lie in the steel cable expansion system. Failure of balance valve or air in oil pipe is also the main reason why the boom can't be retracted. If the air enters due to the leakage of oil inlet pipe, the leakage can be eliminated first, and then the control rod can be pulled repeatedly to make the gas return to the oil tank along the oil return path; if the balance valve is faulty,

平衡阀到下腔进油口的空心螺栓,让伸缩缸下腔液压油从接头缝隙中慢慢流出,这时伸缩臂在自重作用下会自动缩回,然后再检查平衡阀控制油口小孔是否堵塞。 钢板桩围堰方案在一些水深及地质较软的地基施工中具有独特的优势钢板桩围堰的主要形式有矩形,多边形及圆形等,当前钢板桩围堰设计及施工主要靠经验算法,
Slowly unscrew the hollow bolt from the balance valve to the oil inlet of the lower chamber to let the hydraulic oil in the lower chamber of the expansion cylinder flow out of the joint gap slowly. At this time, the expansion arm will automatically retract under the self weight, and then check whether the small hole in the control oil inlet of the balance valve is blocked. The scheme of steel sheet pile cofferdam has unique advantages in the construction of some deep water and soft geological foundation. The main forms of steel sheet pile cofferdam are rectangle, polygon and circle. At present, the design and construction of steel sheet pile cofferdam mainly rely on experience algorithm,
但此种算法往往会与实际出现较大的偏差,为围堰埋下不稳定的因素,而若从理论算法上来求解围堰的实际受力状况,就可以合理的布设内横撑,从而维持钢板桩围堰的稳定性。在进行钢板桩围堰施工作业时,必须先做好施工准备工作,主要包括复查钢板桩,检查振动锤及处理钢板桩等。
However, this algorithm often has a big deviation from the actual situation, which is the factor of the instability of the cofferdam. If we solve the actual stress condition of the cofferdam from the theoretical algorithm, we can reasonably arrange the internal transverse brace, so as to maintain the stability of the steel sheet pile cofferdam. During the construction of steel sheet pile cofferdam, the construction preparation must be done first, mainly including rechecking steel sheet pile, checking vibration hammer and handling steel sheet pile, etc.
本工程采用DZ-60Y型振动桩锤及15吨吊车作业,为保证工程能顺利进行,在打桩之前对振动锤进行了一系列作业测试,结果表明该振动捶功能正常,为剔除那些因装卸运输而导致磨损的变形钢板桩,在钢板桩拼组之前对钢板桩进行了详细的检查,并对锁口破裂及表面有焊接残瘤的钢板桩进行处理,保证单独的围堰钢板桩具有相同的锁口,并在锁口内涂抹适量黄油以减少钢板桩之间的摩损。
In this project, dz-60y vibro hammer and 15t crane are used for operation. In order to ensure the smooth operation of the project, a series of operation tests are carried out on the vibro hammer before driving. The results show that the vibro hammer function is normal. In order to remove the deformed steel sheet piles that are worn due to loading and unloading transportation, the steel sheet piles are inspected in detail before assembling, and the lock opening fracture and surface are also inspected The steel sheet piles with welding residues shall be treated to ensure that the separate steel sheet piles of cofferdams have the same lock mouth, and appropriate butter shall be applied in the lock mouth to reduce the friction between the steel sheet piles.
