摘要
介绍了一种可增力的油缸对顶式夹持器。采用对称结构布置,两边各设置一组增力装置,可将油缸产生的夹持力通过杠杆增力原理作用于钻杆上,具有外形尺寸小、夹紧力大等优点。对夹持器主要设计参数的选择和计算过程做了详细介绍。
This paper introduces a boosting type cylinder clamp with symmetrical arrangement of force increasing device on both sides.The clamping force produced by cylinder acts on the drill rod based on lever boosting principle.This clamp has the advantages of small size and high clamping ability.The selection of the main design parameters and the calculation process are introduced in detail.
