經(jīng)過計(jì)算分析,活塞桿彎曲的原因是動(dòng)臂油缸的兩端與機(jī)架和動(dòng)臂一起傾斜,支撐寬度過小,表明裝配調(diào)整間隙不合適?;騻?cè)面磨損嚴(yán)重,應(yīng)增加支撐寬度;沉積物在缸體下端的積累和動(dòng)臂缸下端的磨損表明,沉積物已嚴(yán)重積累,旋轉(zhuǎn)摩擦較大。
Through calculation and analysis, the reason of piston rod bending is that both ends of boom cylinder incline together with the frame and boom, and the support width is too small, which indicates that the assembly adjustment clearance is not appropriate. The accumulation of sediment in the lower end of the cylinder block and the wear of the lower end of the boom cylinder show that the deposit has accumulated seriously and the rotary friction is large.
改進(jìn)措施包括:
Improvement measures include:
1.增加支撐寬度。通常,支撐寬度是活塞桿直徑的1.2到1.5倍。
1. Increase the support width. Generally, the support width is 1.2 to 1.5 times the diameter of the piston rod.
2.在組裝過程中,請(qǐng)充分利用調(diào)節(jié)墊,以確保動(dòng)臂油缸兩端與機(jī)架和動(dòng)臂之間的間隙和對(duì)齊,并提高調(diào)節(jié)墊材料的耐磨性。
2. In the assembly process, make full use of the adjusting pad to ensure the clearance and alignment between the two ends of the boom cylinder and the frame and boom, and improve the wear resistance of the adjusting pad material.
3.完善排放結(jié)構(gòu);增加開孔距離H1和出料板的傾斜角度α,減少毛坯的堆積,有利于物料的順利出料。增加動(dòng)臂油缸下端對(duì)主機(jī)的排放。距離H2是為了促進(jìn)大尺寸石頭的排出。
3. Improve the discharge structure; increase the opening distance H1 and the inclined angle α of the discharge plate to reduce the accumulation of blanks, which is conducive to the smooth discharge of materials. Increase the discharge of the lower end of boom cylinder to the main engine. The distance H2 is to facilitate the discharge of large-sized stones.
4.說明手冊(cè)規(guī)定了定期積聚的物料的要求。改進(jìn)后,活塞桿不再彎曲。
4. The instruction manual specifies the requirements for periodic removal of accumulated materials. After improvement, the piston rod is no longer bent.
