摘 要:石油鉆機剎車系統(tǒng)機構(gòu)是絞車的關(guān)鍵部件，針對使用鉆機帶式剎車系統(tǒng)帶來的許多安全問題，設(shè)計制動系統(tǒng)工作可靠且具有良好的工藝特性的盤式剎車系統(tǒng)。盤式剎車系統(tǒng)主要有剎車盤、鉗架，剎車塊，制動鉗、鉗臂、液壓控制系統(tǒng)組成，制動鉗則由油缸、活塞、調(diào)節(jié)螺母、彈簧等主要零件構(gòu)成,工作原理為油口進油剎車松開，卸油壓剎車，剎車大小由剎把調(diào)節(jié)剎車閥來改變油缸壓大小來實現(xiàn)，從而提高剎車力，增強剎車系統(tǒng)的可靠性和安全性。 論文開頭介紹了設(shè)計此絞車的目的和意義，絞車的發(fā)展、研究現(xiàn)狀以及絞 車的發(fā)展趨勢，再對絞車的參數(shù)進行設(shè)計計算，主要有滾筒的直徑、纏繩層數(shù)、滾筒纏繩的平均直徑，以及絞車游動系統(tǒng)的分析。之后進行絞車結(jié)構(gòu)設(shè)計，包括鉗架結(jié)構(gòu)，液壓缸的結(jié)構(gòu)和剎車鉗的結(jié)構(gòu)等。再對絞車的零部件進行了強度校核，保證其滿足強度要求。 關(guān)鍵詞：鉆機 絞車 剎車系統(tǒng) 設(shè)計
ABSTRACT:Drilling rig brake system mechanism is a key part of hoist, many security problems according to use drilling with brake system, disc brake system design process characteristics is reliable and has good braking system. Disc brake system mainly has the brake disc, clamp frame, brake block, brake clamp, the clamp arm, hydraulic control system, brake clamp is composed of the main parts of cylinder, piston, a regulating nut, spring, the working principle for the oil into the oil unloading hydraulic brake, brake release, brake size by brake adjusting brake valve to change the cylinder pressure is realized, thereby improving the braking force, enhance the reliability and safety of the brake system. This paper first introduces the purpose and significance of the research design of the winch, winch, the development present situation as well as the cutter Development tendency of car, and parameters to the winch design calculations, mainly has the diameter of the drum, drum rope layer, the average diameter of rope wrapped around, as well as the analysis of traveling system of the winch. After the winch structure design, including the clamp frame structure, hydraulic cylinder structure and the brake clamp structure. Parts of the winch of strength check, to ensure that they meet the strength requirements. Keywords: drill winch brake system design |
