摘  要

斜坡壓實(shí)在道路安全中扮演著十分重要的角色。在道路的施工過程中，往往施工的環(huán)境十分惡劣，因此，對(duì)相關(guān)機(jī)械的要求很高。與此同時(shí)，很多使用小型手動(dòng)壓實(shí)機(jī)、自重或者其他的夯實(shí)方法，這些在斜坡壓實(shí)方面就顯得十分無力了，很難實(shí)現(xiàn)?？紤]到這些后，本文借鑒機(jī)器人手臂原理，可以較好地實(shí)現(xiàn)斜坡壓實(shí)。

本文的設(shè)計(jì)中，主要是參考機(jī)器人手臂的連桿原理，設(shè)計(jì)方案以TY220推土機(jī)為主牽引機(jī)，在TY220推土機(jī)一側(cè)連接壓實(shí)裝置。經(jīng)過相關(guān)結(jié)構(gòu)的運(yùn)動(dòng)分析后，了解到振動(dòng)輥和壓實(shí)機(jī)構(gòu)的大臂是壓實(shí)機(jī)的重要部件。在本設(shè)計(jì)中，嚴(yán)格的對(duì)振動(dòng)輥、和相關(guān)液壓缸以及大臂進(jìn)行了選型和計(jì)算，并且根據(jù)材料力學(xué)所學(xué)的知識(shí)進(jìn)行了相關(guān)的校核。由于設(shè)計(jì)要求主要是對(duì)機(jī)械系統(tǒng)的設(shè)計(jì)，所以液壓系統(tǒng)只是進(jìn)行了液壓缸的設(shè)計(jì)和選型。

ABSTRACT

The roadbed side slope compaction has the vital significance in road safety. Because the work surfaces in construction of the side slope is very narrow, it always has a high request to the construction machinery.t At the same time, because of the slope question, it is very difficult to control and achieve the perfect effect compactness for self-possessed or other ways to the majority of uses in the plane construction compacting plant. Based on these, this paper designed a robot at the same time can well realize the subgrade slope compaction operation of subgrade slope compactor.

The design of this article is a reference link principle of robot arm, using arm, forearm, scaling mechanism, design of various institutions such as the appearance and combining TPZ5 subgrade slope type roller TY220 bulldozer as adopted by the host, in the side of the bulldozer linkage rigid connection design scheme of the compaction mechanism. According to the kinematic analysis of the structure,vibrating roller and big arm are key components in the device, so the scheme selection, in this paper, the dynamics analysis, kinematics analysis and strength check were described in detail and in strict accordance with the calculation and analysis mathematical logic and principle of material mechanics. Due to the requirement of design is mainly to the design of mechanical system, so the design of the hydraulic system is hydraulic cylinder and selection.

Key words: vibration roller;Subgrade slope;The hydraulic cylinder;The big arm
