摘 要
礦井提升設(shè)備是沿井筒提升礦石、廢石、升降人員和設(shè)備、下放材料的大型機械設(shè)備。它是礦山井下生產(chǎn)系統(tǒng)和地面工業(yè)廣場相連接的樞紐、是礦山運輸?shù)难屎?。因此，礦井提升設(shè)備在礦井生產(chǎn)全過程中占有及其重要的地位。
隨著科學(xué)技術(shù)的發(fā)展及生產(chǎn)的機械化和集中化，目前，世界上經(jīng)濟比較發(fā)達的一些國家，提升機的運輸速度已達，一次提升量達到，電動機容量已經(jīng)超過，其安全可靠性尤為突出。在礦井生產(chǎn)過程中，如果提升設(shè)備出現(xiàn)了故障，必然會造成停產(chǎn)。輕者，影響礦石產(chǎn)量，重者，則會危及人身安全。
此外，礦山提升設(shè)備是一大型的綜合機械－電氣設(shè)備，其成本和耗電量比較高，所以，在新礦井的設(shè)計和老礦井的改建設(shè)計中，確定合理的提升系統(tǒng)時，必須經(jīng)過多方面的技術(shù)經(jīng)濟比較，結(jié)合礦井的具體條件，保證提升設(shè)備在選型和運轉(zhuǎn)兩個方面都是合理的，即要求礦井提升設(shè)備具有經(jīng)濟性。
液壓系統(tǒng)主要由動力元件、執(zhí)行元件、控制元件、輔助元件及傳動介質(zhì)五大部分組成。具有以下特點：通過能量的相互轉(zhuǎn)換在運行過程中具有平穩(wěn)無間隙傳動功能，以實現(xiàn)大范圍的無級變速，簡化傳動；可自動循環(huán)工作、自動過載保護；在同等功率輸出情況下，液壓傳動裝置具有體積小、質(zhì)量輕、運動慣性小、動態(tài)性能好等特點；由于油作為傳動介質(zhì)，液壓元件具有自我潤滑作用，壽命延長，且液壓元件都是標準化、系列化產(chǎn)品，便于互換和推廣應(yīng)用。

ABSTRACT
Mine is along the shaft upgrade equipment upgrade ore, waste rock, the movements of personnel and equipment, the decentralization of large-scale machinery and equipment. It is mine and mine production systems connected to the ground at the industrial hub of the transport is mine throat. Therefore, upgrading equipment in the mine shaft in the whole process of production and occupy an important position.
With the development of science and technology and production mechanization and decentralization, at present, the world economy is relatively developed in some countries, upgrading the transport plane has speed, the first upgrade of reach, the motor has exceeded capacity, particularly in its security and reliability. Mine production in the process of upgrading equipment if a fault, will inevitably cause shutdown. Light, the impact of ore production, weight, will endanger their personal safety.
In addition, the mine is a major upgrade of equipment and Machinery - electrical equipment, the cost and power consumption is relatively high, therefore, the design of the new and old mine shaft into the design, determine a reasonable upgrade system, must go through various technical Economy, with the specific conditions of the mine to ensure that upgrading equipment in the selection and operation of the two aspects are reasonable, which called for mine equipment upgrade of an economic nature.
The main driving force from the hydraulic system components, the implementation of components and control devices, components and auxiliary transmission medium five major components. Has the following characteristics: the conversion of energy in the process of running a smooth seamless transmission functions, in order to achieve a wide range of CVT, simplifying transmission; automatically cycle work, automatic overload protection; power output in the same circumstances, the hydraulic Transmission device with small size, light weight, small movement of inertia, good dynamic performance characteristics as a transmission medium because of oil, hydraulic components are self-lubricating, life extension, and hydraulic components are standardized, and serialization of products, facilitate inter - For the promotion and application.
Key words: mine upgrade equipment; hydraulic system
