【摘要】:隨著我國現(xiàn)代化進(jìn)程的發(fā)展,煤炭資源的需求量不斷加大,對立井提升系統(tǒng)的安全、高效生產(chǎn)提出了更高的要求。調(diào)繩作業(yè)是立井提升系統(tǒng)維護(hù)必須進(jìn)行的一項(xiàng)重要工作。調(diào)繩作業(yè)的安全、快速進(jìn)行是依靠可靠的調(diào)繩裝置及調(diào)繩工藝來保證的,F(xiàn)有的調(diào)繩裝置功能單一、只能調(diào)節(jié)安裝側(cè)鋼絲繩、松繩困難、不能實(shí)現(xiàn)對提升系統(tǒng)的安全保護(hù),已經(jīng)無法滿足使用需求。 本課題通過對現(xiàn)有國內(nèi)外調(diào)繩裝置的對比分析,針對其不足,充分考慮現(xiàn)場實(shí)際使用需求,提出了多功能調(diào)繩裝置的總體方案,使其能夠?qū)崿F(xiàn)調(diào)繩功能、安全保護(hù)功能和卡繩功能。本文設(shè)計(jì)了該裝置的機(jī)械、液壓、電控部分,介紹了各部分的組成以及各功能的實(shí)現(xiàn)。 通過分析多功能調(diào)繩裝置的各工況和現(xiàn)有的楔形鎖繩裝置,本文設(shè)計(jì)了新的齒輪齒條式鎖繩部件,并對其抓捕動(dòng)態(tài)鋼絲繩及夾緊靜態(tài)鋼絲繩進(jìn)行了力學(xué)分析,指出安全保護(hù)抓捕時(shí)鋼絲繩受到的摩擦力應(yīng)小于鋼絲繩最小破斷拉力以及鎖繩部件的自鎖條件。應(yīng)用ADAMS軟件對齒輪齒條式鎖繩部件的鎖繩過程進(jìn)行了動(dòng)力學(xué)仿真,仿真結(jié)果表明齒輪齒條式鎖繩部件能夠在不同工況時(shí)安全可靠的鎖緊鋼絲繩,為多功能調(diào)繩裝置各功能的實(shí)現(xiàn)提供了基礎(chǔ)。 安全保護(hù)功能的抓捕響應(yīng)時(shí)間與抓捕同步性是安全保護(hù)抓捕的關(guān)鍵參數(shù)。使用蓄能器作為安全保護(hù)抓捕時(shí)的動(dòng)力源,在AMESim軟件中仿真研究蓄能器對抓捕響應(yīng)時(shí)間的影響。在AMESim軟件中仿真研究液壓同步分流馬達(dá)對抓捕同步性的影響,仿真結(jié)果表明使用液壓同步分流馬達(dá)后,,安全保護(hù)抓捕的抓捕同步性誤差不超過3%,能夠滿足實(shí)際使用需求。 多功能調(diào)繩裝置工作時(shí)載荷最終都會傳遞到承載部件上,多功能調(diào)繩裝置的承載部件主要由移動(dòng)鎖繩器和下鎖繩器的主板、移動(dòng)鎖繩器的移動(dòng)承載組件以及承載底座組成。本文分析了主板、移動(dòng)承載組件和短承載梁的受力情況,做出初步結(jié)構(gòu)設(shè)計(jì)。應(yīng)用Solidworks軟件對主板、移動(dòng)承載組件和短承載梁進(jìn)行了三維實(shí)體參數(shù)化建模,并利用ANSYS Workbench軟件對其進(jìn)行了靜力學(xué)分析和結(jié)構(gòu)優(yōu)化設(shè)計(jì),得到較為合理的結(jié)構(gòu),為其設(shè)計(jì)提供了理論依據(jù)。
[Abstract]:With the development of China's modernization process, the demand for coal resources is increasing, and the safety and efficient production of the antithetical well hoisting system has put forward higher requirements. Rope adjustment is an important task in the maintenance of shaft hoisting system. The safety and speed of rope adjusting operation are guaranteed by reliable rope adjusting device and rope adjusting technology. The existing rope adjusting device has a single function and can only adjust the installation side of the wire rope. It is difficult to loose the rope and can not realize the safety protection of the lifting system and can no longer meet the needs of use. Based on the comparative analysis of the existing domestic and foreign rope regulating devices and considering their shortcomings, the overall scheme of the multi-function rope adjusting device is put forward in order to realize the rope adjusting function. Safety protection function and rope clamp function. In this paper, the mechanical, hydraulic and electronic control parts of the device are designed, and the composition of each part and the realization of each function are introduced. Based on the analysis of the various working conditions of the multi-function rope adjusting device and the existing wedge-shaped locking rope device, a new gear and rack type locking rope component is designed, and the mechanical analysis of its capture of dynamic wire rope and clamping static wire rope is carried out. It is pointed out that the friction force of wire rope should be less than the minimum breaking force of wire rope and the self-locking condition of lock rope. The dynamic simulation of the lock rope process of the gear rack type lock rope component is carried out by using ADAMS software. The simulation results show that the gear rack type lock rope component can secure and reliable lock steel wire rope under different working conditions. It provides the foundation for the realization of the various functions of the multifunctional rope adjusting device. The capture response time and synchronization of security protection function are the key parameters of security protection arrest. The accumulator is used as the power source of safety protection and capture. The effect of accumulator on the capture response time is simulated in AMESim software. The effect of hydraulic synchronous shunt motor on catching synchronicity is studied by simulation in AMESim software. The simulation results show that after using hydraulic synchronous shunt motor, the catch synchronicity error of safety protection arrest is less than 3 parts, which can meet the need of practical use. The load of the multi-function rope adjusting device will be transferred to the bearing part when it works. The bearing part of the multi-function rope adjusting device is mainly composed of the main board of the moving-rope locking device and the lower locking device, the moving load-carrying component of the moving-rope latching device and the bearing base of the moving-rope latching device. In this paper, the stress of main plate, moving bearing component and short bearing beam is analyzed, and the preliminary structural design is made. The 3D solid parametric modeling of the main board, moving load-bearing component and short load-bearing beam is carried out by using Solidworks software, and the statics analysis and structural optimization design are carried out by using ANSYS Workbench software, and a more reasonable structure is obtained. It provides a theoretical basis for its design.
