滩海沼泽工程施工车辆的辅助液压蟹爪机构

The auxiliary hydraulic crab mechanism for vehicles in the beach-shallow-swamp area

在沼泽、滩涂、浅水域，运输人员、物资和从事工程作业的车辆，必须具有对地比压低的特点，为此分析了软弱地基对车辆通过性能的影响，提出在不改变机型参数的条件下，采用易于装卸的辅助液压蟹爪机构，克服普通工程机械对地比压高的问题，以提高设备的机动性和应急能力，并探讨了液压机构形式和在软地基中防干扰问题。

The vehicles transporting persons and goods in the beach-shallow-swamp area must havethe characteristics of low specific pressure to the ground. This paper analyzes the affection 0f softfoundation to the performance of vehicles passing through, and provides the addption of auxiliaryhydraulic crab mechanismtto solve the problem of high specific pressure to the ground created bythese vehicles without changing their machine type and basic parameters. This paper also discuss-es the form of hydraulic mechanism and the way to eliminate disturbance of soft foundati0n. Thisstudy shows that the crab mechanism has wide applying prospects.
