摘    要

      路面切槽机作为公路及城市道路养护的专用设备，主要应用于公路、机场、码头、货厂、停车场、车间等沥青混凝土路面的切割修补，伸缩缝切割，施工现场非金属构件的切割，使用于管线电缆沟施工前的破基切割。路面切槽机通过四连杆机构可以调整切割深度，采用切割卡轮，保证锯片不跑偏，保证切割准确。切割轴的端部加调整螺母，通过调整螺母可调整切割宽度。切割刀片采用金属镶焊金刚石结块材料制成，使用寿命长。路面切槽机是由行走系统、升降系统、冷却系统等组成。本设计主要对路面切槽机的整体进行方案设计，对行走部分、切割部分结构及传动等相关设计。此机采用无充气橡胶垫轮胎式行走车轮，驱动力由电机供给。切割系统通过变速器可以实现逆向切割三级变速；行走系统通过变速器实现三级变速，并可实现正反转、慢速切割快速后退。切割系统与行走系统通过不同的速度搭配以适应不同的切割情况要求。本设计创新点：在变速器中采用空套齿轮、花键轴、内摩擦片和外摩擦片组成的离合器来实现传动系统随时分离和接合，在行走系统中采用惰轮和三联滑移齿轮，实现速度要求；切割宽度具体由套筒调节，为增加附着力，安装四个车轮。该机具有良好的动力性能，极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
