【摘要】：在液壓鑿巖機(jī)進(jìn)行鑿巖作業(yè)時(shí),雖然鑿巖機(jī)具有自動(dòng)防卡釬功能,但由于存在巖石質(zhì)地不均、裂隙或熔巖等原因,卡釬事故經(jīng)常發(fā)生。一旦發(fā)生卡釬事故,鉆頭和釬桿將會(huì)被卡在孔壁中而無(wú)法拔出,只能放棄已經(jīng)鉆進(jìn)孔內(nèi)的釬桿和鉆頭,從而大幅降低鑿巖開(kāi)孔速度和鑿巖效率。為提高鑿巖機(jī)自動(dòng)防卡釬系統(tǒng)的響應(yīng)速度和穩(wěn)定性,降低卡釬率,對(duì)其動(dòng)靜態(tài)特性進(jìn)行了分析及改進(jìn)。主要工作如下:(1)搭建仿真模型。利用AMESim仿真軟件對(duì)鑿巖機(jī)防卡釬液壓系統(tǒng)進(jìn)行了建模;根據(jù)實(shí)際液壓元件結(jié)構(gòu)參數(shù)及系統(tǒng)工作參數(shù),對(duì)模型仿真參數(shù)進(jìn)行了設(shè)置;并通過(guò)靜態(tài)試驗(yàn)驗(yàn)證了仿真模型的準(zhǔn)確性,為動(dòng)態(tài)特性分析奠定了基礎(chǔ)。(2)系統(tǒng)動(dòng)態(tài)特性分析。利用鑿巖機(jī)自動(dòng)防卡釬液壓系統(tǒng)AMESim仿真模型,對(duì)不同工況下的防卡釬閥、推進(jìn)系統(tǒng)、轉(zhuǎn)釬系統(tǒng)及防卡釬系統(tǒng)動(dòng)態(tài)特性進(jìn)行了分析。(3)系統(tǒng)動(dòng)態(tài)特性改進(jìn)。基于仿真模型,探索了影響防卡釬系統(tǒng)動(dòng)態(tài)特性的敏感結(jié)構(gòu)參數(shù);采用多因素正交試驗(yàn)法,分析出了各敏感結(jié)構(gòu)參數(shù)對(duì)系統(tǒng)動(dòng)態(tài)特性的影響程度,確定了最佳參數(shù)組合。(4)實(shí)車(chē)試驗(yàn)。完成了液壓鑿巖機(jī)實(shí)車(chē)試驗(yàn),結(jié)果表明,敏感結(jié)構(gòu)參數(shù)改進(jìn)后的防卡釬系統(tǒng),可有效的提高系統(tǒng)的穩(wěn)定特性,降低卡釬率。
[Abstract]:Although the drilling machine has the function of preventing the rock drill automatically, the rock drill often occurs because of the uneven texture of the rock, the crack or the lava and so on. Once the drill bit accident occurs, the drill bit and the drill rod will be stuck in the hole wall and cannot be pulled out, so the drill rod and bit already drilled in the hole can only be abandoned, thus greatly reducing the drilling speed and drilling efficiency. In order to improve the response speed and stability of the drill system and reduce the drill bit rate, the dynamic and static characteristics of the drill are analyzed and improved. The main work is as follows: (1) build the simulation model. The hydraulic system of rock drilling machine is modeled by AMESim software, and the simulation parameters are set according to the structure parameters and system working parameters of the actual hydraulic components. The accuracy of the simulation model is verified by static test, which lays a foundation for dynamic characteristic analysis. (2) system dynamic characteristic analysis. Based on the AMESim simulation model of hydraulic system of rock drill, the dynamic characteristics of drill valve, propulsion system, rotary brazing system and anti-drill system under different working conditions are analyzed. (3) the dynamic characteristics of the system are improved. Based on the simulation model, the sensitive structural parameters which affect the dynamic characteristics of the brazing system are explored. By using the method of multi-factor orthogonal test, the influence degree of each sensitive structural parameter on the dynamic characteristic of the system is analyzed, and the best parameter combination is determined. (4) the actual vehicle test. The actual test of hydraulic rock drill has been completed. The results show that the system with improved sensitive structure parameters can effectively improve the stability of the system and reduce the drill bit rate.
