Description

平移传动结构
技术领域：
本实用新型涉及一种平移传动结构。
背景技术：
目前，原有的手术床的平移结构存在一定的局限性：占用安装范围较大，对手术床的紧凑运动空间安排有困难；平移行程较短，难以满足手术过程中对病人进行无遮挡透视要求（平移功能就是为了能让出床体立柱的位置来实现全身的透视，行程偏小就让不出立柱位置，影响全身透视的效果）；电动推杆的平移结构，遇到故障损坏易发生自脱现象。
实用新型内容：
本实用新型的目的是为了克服以上的不足，提供了一种更合理、更实用、更安全可靠的实用新型平移传动结构。
本实用新型的目的通过以下技术方案来实现：一种平移传动结构，包括座架，座架上的平移轨道组件上连接有方架，方架下方通过固定板连接有螺母，螺母中有平移丝杆穿过，平移丝杆一端连接在同步轮上并通过固定搭子固定，同步轮同步带带动旋转，同步带内的另一个同步轮连接在直流电机上，同步带带动同步轮及丝杆和螺母的传动结构。
本实用新型与现有技术相比具有以下优点：通过丝杆螺母的结构应用可以防止自脱，安全性能得以增强；隐藏式的安装占用空间较小；而且能满足多种平移行程的需求。
附图说明：
图1是本实用新型的主视图；
图2是本实用新型的右视图；
图中标号：1-座架、2-方架、3-直流电机、4-平移丝杆、5-螺母、6-平移轨道组件、7-轨道固定板、8-同步轮、9-同步带、10-固定搭子、11-固定板。
具体实施方式：
为了加深对本实用新型的理解，下面将结合实施例和附图对本实用新型作进一步详述，该实施例仅用于解释本实用新型，并不构成对本实用新型保护范围的限定。
如图1、2所示的一种新型平移传动结构的实施方式，包括座架1、方架2、直流电机3、平移丝杆4、螺母5、平移轨道组件6、轨道固定板7、同步轮8、同步带9、固定搭子10、固定板11；所述直流电机3固定在座架1内侧板上，伸出侧板部分安装有同步轮8；在所述平移丝杆4的一端通过固定搭子10固定，并在超出固定搭子10的部分安装同步轮8；在上述两个同步轮8之间由同步带9相连接；在上述平移丝杆4的另一端，通过螺入螺母5的孔内，来达到相对固定的作用；在上述座架1与方架2之间通过平移轨道组件连接，位置要与平移丝杆4相对平行；
平移传动结构中直流电机的设计安装在座架内部，不占用床面运动的空间，在直流电机3通电运动下，通过同步轮8、同步带9的传动，带动平移丝杆4在螺母5中转动，节省了安装空间，方便了平移行程的调节，螺母5是固定在方架2上的，平移丝杆4一端是固定在座架1上，另一端通过与螺母5间的运动，来实现座架1与方架2之间的移动，达到手术床平移的功能效果（行程可根据手术床立柱尺寸调节）；方便了手术过程中仪器设备对病人全身透视的操作需要。
