Description
技术领域
本实用新型涉及阻尼装置，尤其涉及一种用于旋转装置的阻尼机构。
背景技术
在油田设备上，如压裂车、液氮车等，由于方便运输和便于操作的综合考据，对一些部件通常要做成可折叠的形式，如设备上的爬梯，操作平台上的护栏等等。这种折叠结构就是将一个整体件分成可折叠的几段，个段之间一般以销轴铰接连接。在运输中需要折叠起来以节省空间，在使用时需要展开以发挥功能。由于设备比较庞大，这些折叠部件通常也具备较大重量，因此在翻转或回转操作中，比较笨重，并且由于急速翻转还存在安全隐患。
实用新型内容
本实用新型针对上述现有技术的不足，提供一种可以给相互铰接的两个部件在翻转操作时提供一定阻尼缓冲作用的用于旋转装置的阻尼机构。
本实用新型解决上述技术问题的技术方案如下：一种用于旋转装置的阻尼机构，包括相互铰接的转动部件、固定部件及销轴，其特征在于，所述销轴与所述固定部件固定连接，所述销轴上套装有转动组件、扭簧及固定组件，所述转动组件包括固定在所述销轴上的轴承、以及套装在所述轴承外圈上的转动板，所述转动部件与所述转动板固定连接，所述固定部件与所述销轴连为一体，所述扭簧设于所述固定组件和转动组件之间，所述扭簧的一端与所述转动板固定连接，另一端与所述固定组件固定连接。
进一步，所述阻尼机构成对设置。
本实用新型的有益效果是：当转动部件翻转到与固定部件折叠时，所述扭簧在所述转动组件的带动下旋转，在对转动部件起到阻尼作用同时，自身积蓄了扭矩能量；当需要转动部件旋转到打开位置时，在转动前期，扭簧积蓄的能量给转动部件的转动助力，而转动到后期时，扭簧又起到了反向阻尼作用并积蓄扭矩。采用本实用新型使得转动部件翻转更平稳，更安全。
附图说明
图1为本实用新型的结构示意图；
图2为沿图1中A-A向看到的转动部件与固定部件折叠时局部状态图；
图3为沿图1中A-A向看到的转动部件打开时时局部状态图。
在图1到图3中，1、固定部件；2、转动部件；3、销轴；4、转动组件；5、扭簧；6、轴承；7、固定组件；8、转动板。
具体实施方式
以下结合附图对本实用新型的原理和特征进行描述，所举实例只用于解释本实用新型，并非用于限定本实用新型的范围。
如图1所示，一种用于旋转装置的阻尼机构，包括相互铰接的转动部件2、固定部件1及销轴3，所述销轴3与所述固定部件1固定连接，所述销轴3上套装有转动组件4、扭簧5及固定组件7，所述转动组件4包括固定在所述销轴3上的轴承6、以及套装在所述轴承6外圈上的转动板8，所述转动部件2与所述转动板8固定连接，所述固定部件1与所述销轴3连为一体，所述扭簧5设于所述固定组件1和转动组件4之间，所述扭簧5的一端与所述转动板8固定连接，另一端与所述固定组件7固定连接。
所述阻尼机构成对设置。
如图2所示，为沿图1中A-A向看到的转动部件与固定部件折叠时局部状态图，当转动部件2翻转到与固定部件1折叠时，所述扭簧5在所述转动组件4的带动下旋转，在对转动部件2起到阻尼作用同时，自身积蓄了扭矩能量。
如图3所示，当需要转动部件2旋转到打开位置时，在转动前期，扭簧5积蓄的能量给转动部件的转动助力，而转动到后期时，扭簧5又起到了反向阻尼作用并积蓄扭矩能量。
以上所述仅为本实用新型的较佳实施例，并不用以限制本实用新型，凡在本实用新型的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本实用新型的保护范围之内。
