Abstract

本实用新型公开了一种夹桩油缸,包括缸筒、活塞杆、导向套、密封圈、设于活塞杆内的两油路,其特征在于导向套设有与缸筒端口配合的台肩,缸筒端口与导向套的台肩通过数个螺钉固联。本实用新型具有导向套稳定性好的优点,提高了油缸的可靠性。

Description

夹桩油缸
技术领域
   本实用新型涉及一种用于静压桩机的夹桩油缸。
背景技术
目前用于静压桩机上的夹桩油缸,如图1所示,包括缸筒1、活塞杆2、导向套3、密封圈、设于活塞杆内的两油路,在导向套3外侧的缸筒1内设有环槽,环槽内设有分段式的卡键8,再通过与导向套3固联的端盖9对导向套3和卡键8定位;夹桩油缸的使用工况较为特殊,其长度尺寸受到限制,结构十分紧凑,但该结构的夹桩油缸由于卡键8和端盖9的存在,使得导向套3的长度偏短,导向套3受力时的稳定性较差,导致导向套3损坏或漏油,难以保证油缸的可靠性。
实用新型内容
本实用新型的目的在于针对现有技术的上述不足,提供一种夹桩油缸,它具有导向套稳定性好的优点,提高了油缸的可靠性。
  为达到上述目的,本实用新型的夹桩油缸,包括缸筒、活塞杆、导向套、密封圈、设于活塞杆内的两油路,其特征在于导向套设有与缸筒端口配合的台肩,缸筒端口与导向套的台肩通过数个螺钉固联。
本实用新型通过螺钉将导向套与缸筒固联,取消了卡键和端盖,不仅增加了导向套的长度,而且导向套与缸筒联接其稳定性增强,避免了导向套损坏或漏油,提高了油缸的可靠性。
附图说明
图1为现有夹桩油缸的结构简图。
图2为本实用新型实施例的结构简图。
具体实施方式
下面结合附图对本实用新型作进一步详细的说明。
  由图2所示,该压桩油缸,包括缸筒1、活塞杆2、导向套3、密封圈、设于活塞杆2内的两油路4和5,导向套3设有与缸筒端口配合的台肩,缸筒端口与导向套3的台肩通过数个螺钉6固联。
本实用新型通过螺钉6将导向套3与缸筒1固联,取消了原有的卡键和端盖,不仅增加了导向套3的长度,而且导向套3与缸筒1联接其稳定性增强,避免了导向套3损坏或漏油,提高了油缸的可靠性。
