摘　　要：对某型踏面制动单元停放制动状态及手动缓解原理进行介绍,包括制动缸不同状态下的作用原理及作用方式。针对目前采用单侧缓解的停放制动缸,分析其存在的劣势并提出改造要求。根据停放制动缸周围安装位置的不同提出三种将单侧缓解改为双侧缓解的方案,并对三种方案进行详细对比分析,包括改动范围、所需空间尺寸及改造费用等。结合某项目的实际需要,综合分析对比后给出拟采用的改造方案,并对该改造方案进行详细阐述,从而为踏面制动单元手动缓解改造需求提供参考。In this thesis,the braking state of a certain tread brake unit and the principle of manual relief is introduced,including the principle and mode of action of the brake cylinder in different states.In view of the current parking brake cylinder with unilateral relief,the disadvantages are analyzed,and the conclusion is drawn that it needs to be reformed.According to the different installation positions around the parking brake cylinder,three schemes of changing unilateral relief to bilateral relief are proposed;then the three schemes are compared and analyzed in detail,including the scope of change,the required space size and the renovation cost.Combined with the actual needs of a project,the proposed transformation scheme is given after comprehensive analysis and comparison,and the scheme is elaborated in detail to provide a reference for the manual mitigation transformation needs of tread brake unit.
