【摘要】 随着工业化进程的快速发展,能源浪费现象已引起世界各国的广泛关注,再加上能源紧缺和油价上涨,节能也就成为科技人员的主要研究方向。在工程机械中,占路面机械市场的绝大部分的沥青混合料搅拌设备就存在能源浪费现象。而沥青混合料搅拌设备是沥青路面施工的关键设备,为此,研究沥青搅拌设备的节能是很有必要的。本文以J4000型集装箱式沥青混合料搅拌设备为基础,以基于系统势能和系统动能节能方法为依据,对沥青搅拌设备成品料提升机构所消耗的能量及功率进行分析研究,提出增加配重体的方法,力求使该机构所输入功率降低和能量得到充分发挥,以达到节能的目的。首先对配重节能进行可行性分析,经分析可知,配重节能是完全可行的。其次通过设计多种配重节能方案,分析其优点及不足,最后确定最优配重节能方案。为了使节能达到最理想效果,本文采用了机械配重和液压配重的有效结合方法,通过动滑轮组,使钢丝绳一端与料斗连接,另一端与配重块连接。动滑轮组可以很好的解决钢丝绳长度问题。配重块做成液压升降机形式,这样就可以避免因钢丝绳断裂而伤及人员的现象。为了充分利用空载料斗下降时所具有的势能,在料斗上安装一个发电机构,当料斗下降时,势能转换为电能,电能又通过转换机构转换为液压能,储存到蓄能器中,而蓄能器可以提供一部分能量给配重支架。为了避免飞车事故和生产需要,需要把料斗放置在某一位置,可以通过增加阻车器解决此类问题。该阻车器是一种自动闭锁装置,处于常开状态。当阻车器上的传感器感应到料斗上的电磁感应器时,则活塞杆自动回收,该阻车器还具有手动功能。为了检验本设计是否满足生产要求,在ADAMS仿真软件中,对配重节能进行仿真与分析。经过仿真分析,我们可以看出,配重节能可以很好的达到节能效果。基于增加配重体设计成功用于生产,将大大提升搅拌设备的性能,可以广泛地被推广到电梯、塔吊、升降机、起重机等机器。故本课题的研究有广泛的应用前景。更多还原

【Abstract】 With the rapid development of industrialization, energy waste has caused widespread concern around the world. Coupled with energy shortages and rising oil prices, it has become the main concern for researchers in the field. In engineering machinery, the asphalt mixing plant which occupies the largest section in the road machinery market constitutes a major source for energy waste. Given the indispensible status of the asphalt mixing plant in road construction equipment, it is necessary to investigate the energy saving strategies for the asphalt mixing equipment.The present research is based on the J4000-type container type asphalt mixing plant exploring the feasible methods for system potential energy saving as well as system kinetic energy saving. is based on the asphalt mixing plant finished materials enhance the body the energy consumption and power analysis and study, proposed to increase the weight the body of the method In effort to reduce the agency and the energy input power into full play in order to achieve energy saving.First, a feasibility analysis of weight saving, the analysis showed that the weight saving is entirely feasible. Second, by listing a variety of weight saving program, analyze the advantages and disadvantages, and finally to determine the final weight saving program.In order to achieve the best energy-saving effect, the paper finally adopted hydraulic mechanical weight and weight of the effective combination of methods, through the moving pulley blocks, wire rope connected at one end with the hopper, the other end and connected with weights. Moving pulley rope length can solve the problem. Weight block made of hydraulic lift in the form, so you can avoid injuries to personnel due to wire fracture of the phenomenon. To take advantage of no-load potential energy contained in the hopper drops, to install a power generation sector hopper when the hopper falls, potential energy is converted to electrical energy, electrical energy is converted to another institution by converting the hydraulic energy stored in the accumulator. Accumulator can provide some of the energy to weight bracket。In order to avoid runaway accident, or to production needs, should be placed in a position hopper can be resolved by increasing the car stop the problem。The car stop is an automatic locking device, is normally open state. When sensors on the car stop to the hopper of electromagnetic induction sensors, then the rod automatic recovery. The car stop there manual function.。To test whether the design meets the requirements in the ADAMS simulation software, with emphasis on energy efficiency for the simulation and analysis. The simulation analysis can be drawn, the weight saving can be very good to save energy.Increase in body weight based on the design used successfully in production, will greatly enhance the performance of mixing equipment can be widely extended to the elevators, cranes, lifts, cranes and other machines. Therefore, the subject of a wide range of applications.更多还原
