| 摘 要： | 助力装置是非开挖钻机上选配的辅助装置中非常重要的装置，有时直接决定着非开挖工程的成败。分析现有的主流马达助力装置的不足，设计了一种油缸助力装置。利用双自由度机构，实现在助力时齿形部件自动先啮合钻架齿条再达到油缸助力的目的，远程就能实现助力装置自动切换状态，减少人工，缩减成本。

| Abstract: | The auxiliary back pulling device is a very important one among the optional auxiliary devices on the trenchless drilling rig, which directly determines the success of the trenchless project sometimes. Based on the analysis of the current mainstream motor-assisted device, a hydro-cylinder assisted device was designed. A two-degree-of-freedom mechanism is used to allow the tooth-shaped part automatically to engage the rack of the drill mast first and then the cylinder to provide assistance. Automatic switching can be realized remotely; thus reducing labor and costs. |
