摘 要
大型工件、物品的搬运常采用助推器辅助搬运完成作业，主要有机械式、气动式、电动式、液压式等，其工作性能各有优劣，有特定的适用场合。铁路机车或车辆检修维护时的移动一直采用牵引机车或牵车机构牵引，而牵引机车一般为内燃机车，不适合在机车或车辆检修要求越来越高的库内牵引机车用，而牵车机构一般为链式传输机构，其安装空间需要利用轨道中间的部分空间，且建造成本高、运行不稳定、维护成本较高和驱动电机的防水防潮功能要求较高，使用效果一直不理想。
本文拟在综合分析比较现有搬运助推器的工作原理、组成结构的基础上，通过分析机车转向架与助推器的受力作用情况，运用ADAMS软件对助推器的执行机构进行建模和运动仿真，确定了执行杆件的运作方式和受力作用情况，进一步校核各部件，设计出一种用于搬运不同规格机车转向架、适合机车车间工作条件的低耗高效便携式助推器。结构简单，方便组装，方便工人操作的便携式机车牵车装置，为机车检修时方便进出检修库用。

Abstract
Large workpiece and goods' transport often use boosters to help to finish the work.The main means are mechanical, pneumatic, electric, hydraulic.Every means has its own advantages and disadvantages and every means is used in its special appropriate occasion . When the railway locomotive and vehicle are in maintenance,it has often been using traction locomotives or traction mechanism for moving. But the traction locomotive is usually a kind of diesel locomotives.It is not suitable for the traction of locomotive,with the request more and more high in locomotive and vehicle maintenance. The traction mechanism is usually a kind of chain transmission mechanism.The middle part of the space of the orbit is required for the installation space , with high construction costs,unstable operation,high maintenance costs and the higher requirements for drive motors' waterproof function.So the using effect has not been ideal.
This article is on the comprehensive analysis of the working principle and existing boosters' structure. By analyzing the force condition of the locomotive bogie and the booster,using the Adams software for modeling and motion simulation of the executive mechanism of the booster. So the executive members' operation mode and the force function are determined, further checking other parts, designing a kind of portable booster with high efficiency and low consumption for the transport of different specifications of bogies. And it is suitable for the locomotive workshops' working conditions. It is a kind of portable traction device with simple structure, convenient assembly and convenient operation ,for convenient in or out of the maintenance bases when the railway locomotive and vehicle is in maintenance.
Key words: Booster; High Efficiency; Portable; Adams; Motion Simulation
