【摘要】：針對目前進口鉆機的維護費用較高和周期較長,以及國產鉆機的移動性不強等問題,在借鑒了國外同類鉆機的成功經驗的基礎上,本文設計了一種全液壓動力頭式鉆機。整臺鉆機能夠在短時間內拆分為9個相對獨立的模塊。這種模塊化設計降低了鉆機的運輸要求,解決了現(xiàn)有的國產液壓鉆機移動性不強的問題。整機的電氣系統(tǒng)和液壓系統(tǒng)元件大部分采用國產元件,降低了鉆機的維護費用,縮短了鉆機維修保養(yǎng)周期。本設計完成了如下的設計內容:(1)鉆機的主要結構件塔架的結構設計和材料選擇。在確定塔架的總體結構后為焊接式桁架結構后,初步選擇了構成塔架的鋼材型號。分析塔架的兩種危險狀況下的受力情況。選擇然后通過計算機模擬仿真,找出塔架系統(tǒng)的薄弱環(huán)節(jié)并強化。(2)動力系統(tǒng)的選擇。通過對工程機械常用動力輸出系統(tǒng)的特點分析,確定本機原動機的為柴油機。而后通過柴油機負載特性曲線及其實際帶載測試結果劃分出了“柴油機—液壓泵”動力系統(tǒng)的穩(wěn)定工作區(qū)域,并確定了實際工作中的柴油機允許轉速范圍。(3)液壓動力頭的選擇。計算出液壓馬達的輸出參數(shù)。而后根據鉆探工況和施工要求確定液壓動力頭的輸出參數(shù)。選擇合適的減速箱、變速箱和液壓卡盤,完成液壓動力頭的選型和搭建。(4)電氣系統(tǒng)設計。電氣系統(tǒng)包括發(fā)動機的監(jiān)測回路和整機的安全保護回路兩部分。發(fā)動機監(jiān)測回路通過發(fā)動機的ECM系統(tǒng)和多功能顯示器實現(xiàn)。整機安全保護回路以邏輯元件低壓繼電器為核心。針對不同的安全保護情況,制定不同的安全保護措施;最后繪制了整機的電氣原理圖。(5)液壓系統(tǒng)分管路的設計。分析鉆機在部署和施工過程中所需的各個動作。選擇能夠實現(xiàn)鉆機所需的動作的液壓執(zhí)行元件。然后以選定的執(zhí)行元件為核心搭建各個液壓分管路,繪制各個分管路液壓原理圖。
[Abstract]:Aiming at the problems of high maintenance cost and long period of imported drilling rigs, and the low mobility of domestic rigs, a full hydraulic power head drilling rig is designed based on the successful experience of the same kind of drilling rigs abroad. The whole rig can be split into 9 relatively independent modules in a short time. This modular design reduces the transportation requirements of drilling rigs and solves the problem that the mobility of existing domestic hydraulic drilling rigs is not strong. The electric and hydraulic system components of the whole machine are mostly made of domestic components, which reduce the maintenance cost of drilling rig and shorten the maintenance period of drilling rig. This design has completed the following design contents: 1) the structure design and material selection of the main structure tower of drill rig. After determining the overall structure of the tower as a welded truss structure, the steel model of the tower is preliminarily selected. The stress of the tower under two dangerous conditions is analyzed. The weak link of tower system is found and the selection of power system is strengthened by computer simulation. By analyzing the characteristics of common power output system of construction machinery, it is determined that the prime mover of this machine is a diesel engine. Then, the stable working area of the diesel engine hydraulic pump power system is divided by the load characteristic curve of diesel engine and the test results with actual load, and the selection of the hydraulic power head of the diesel engine with allowable speed range of 3) is determined. The output parameters of the hydraulic motor are calculated. Then the output parameters of hydraulic power head are determined according to drilling conditions and construction requirements. Select suitable deceleration box, gearbox and hydraulic chuck, complete the type selection of hydraulic power head and build the electrical system design. The electrical system includes two parts: the monitoring circuit of engine and the safety protection circuit of the whole machine. The engine monitoring loop is realized through the engine ECM system and multi-function display. The whole machine safety protection circuit takes the logic element low-voltage relay as the core. According to different safety protection conditions, different safety protection measures are worked out. Finally, the electrical schematic diagram of the whole machine is drawn. Analysis of the rig in the deployment and construction of the required actions. Select the hydraulic actuator that can perform the required movement of the rig. Then take the selected actuator as the core to build each hydraulic pipeline, draw the hydraulic schematic diagram of each pipeline.
