摘   要

     路面切槽機作為公路及城市道路養護的專用設備，主要應用于公路、機場、碼頭、貨廠、停車場、車間等瀝青混凝土路面的切割修補，伸縮縫切割，施工現場非金屬構件的切割，使用于管線電纜溝施工前的破基切割。路面切槽機通過四連桿機構可以調整切割深度，采用切割卡輪，保證鋸片不跑偏，保證切割準確。切割軸的端部加調整螺母，通過調整螺母可調整切割寬度。切割刀片采用金屬鑲焊金剛石結塊材料制成，使用壽命長。路面切槽機是由行走系統、升降系統、冷卻系統等組成。本設計主要對路面切槽機的整體進行方案設計，對行走部分、切割部分結構及傳動等相關設計。此機采用無充氣橡膠墊輪胎式行走車輪，驅動力由電機供給。切割系統通過變速器可以實現逆向切割三級變速；行走系統通過變速器實現三級變速，并可實現正反轉、慢速切割快速后退。切割系統與行走系統通過不同的速度搭配以適應不同的切割情況要求。本設計創新點：在變速器中采用空套齒輪、花鍵軸、內摩擦片和外摩擦片組成的離合器來實現傳動系統隨時分離和接合，在行走系統中采用惰輪和三聯滑移齒輪，實現速度要求；切割寬度具體由套筒調節，為增加附著力，安裝四個車輪。該機具有良好的動力性能，極高的工作效率和可靠性。

Abstract     Road cutting slot machines as highways and urban roads conservation of     special equipment, mainly used in highways, airports, terminals and cargo plants, car parks, workshops and so on the cutting asphalt concrete pavement repair, cutting the expansion joints, non-metallic components of the construction site cutting, For use in cable ditch pipeline construction before the break-cutting. Road cutting through the slot machines four linkage cutting depth can be adjusted by cutting card round, saw no guarantee that deviation, and ensure accurate cutting. Cutting the end of the shaft and nut adjustment, by adjusting the nut adjustable cutting width. Insert a metal cutting blade of Diamond caking material, long life. The road is cut by the slot machines operating system, the take-off and landing systems, cooling systems and other components. The design of the main road cutting slot machines on the overall programme design, the walking part of the structure and cutting drive, and other related design. The machine adopts the inflatable rubber pad tire-running wheels, driven by the electrical supply. Cutting through the transmission system can achieve reverse cutting three transmission; operating system through the realization of three transmission speed, and achieving positive and, Slow rapid cutting back. Cutting through the system and the operating system with different speeds to adapt to different circumstances require cutting. The design innovations: the use of space in the transmission sets of gears, spline shaft, friction within the film and the film composed of friction clutch drive system at any time to achieve separation and joint, walking in the system used in lazy round and triple sliding gear, And speed; cutting width of the specific regulation by the sleeve, in order to increase adhesion to install four wheels. The aircraft has a good dynamic performance, high efficiency and reliability.     Key words:  cutting;  walk;  three speed
