Description
本发明涉及振动棒技术领域，具体为一种便携式无刷电机振动棒。
振动棒是在工程建设中常用的一种设备，其主要作用是通过振动来使得浇筑的混凝土密室紧合，消除混凝土中蜂窝麻面和内部气泡等现象，提高混凝土成型后的强度，现有的振动棒根据振动分类可分为内部振捣器、外部振捣器和表面振捣器，其中内部振捣器主要用于振压厚度较深的混凝土层，而这种内部振捣器的主要工作原理是通过内部设置的质量分布不均匀的转轴在驱动转动后产生的离心力使得转轴高速且不断地与外部壳体进行摩擦撞击而产生震动，进而对混凝土层进行振动紧实操作，但是现有的振动棒在使用过程中还存在一些问题，具体如下：
现有的内部振捣器类型的振动棒在使用时由于是依靠内部的轴承在质量分布不均匀的情况下高速旋转与外部壳体进行摩擦碰撞产生震动，而由于内部的转轴质量分布不均匀，其在旋转过程中会与外壳内表面产生强烈的摩擦和撞击，这样会严重夹具外壳的磨损，从而会导致可能在振捣的过程中发生振动棒损坏，这样混凝土浆就会灌入到内部，进而导致整个振动棒报废，大大降低了振动棒的使用寿命，同时快速旋转的内部转轴会与外壳内表面不断摩擦，导致外壳上温度不断升高，进而加速外壳的形变以及降低了外壳的刚性，进一步导致外壳的更加容易破损，同时内部的转轴在使用过程中也存在极大的磨损消耗，导致整体振动棒的使用寿命大幅度缩短。

请参阅图1、图2、图3和图4所示的一种便携式无刷电机振动棒，包括套管1，所述套管1的底端可拆卸固定安装有震动外壳2，所述震动外壳2的底端活动安装有底盖3，所述震动外壳2内部中部固定安装有内环轨4，所述震动外壳2内部位于内环轨4的上方活动设置有底座5，所述底座5上表面中部活动安装有连接转轴6，所述连接转轴6上固定套接安装有主动齿轮7，所述底座5的两端分别固定安装有震动发生结构8，所述震动发生结构8的底端与内环轨4的顶端活动接触连接，所述底座5的下表面中部固定安装有转动驱动结构9，所述连接转轴6的顶端可拆卸连接有软轴10，所述软轴10与外部的无刷电机的输出轴固定连接；
与现有技术相比，本申请通过将现有的质量不均匀转轴改为利用震动发生结构8实现敲击产生震动的方式来使得振动棒震动，这样不仅可以利用敲击头86对震动外壳2进行敲击产生强烈的震动，同时也能够避免内部的震动发生结构8与震动外壳2内表面的剧烈的摩擦，大大降低了震动发生结构8以及震动外壳2在使用过程中的损耗情况，进而提高了振动棒整体的使用寿命，降低了工程作业中的投入成本，同时通过转动驱动结构9的设置，使得该振动棒在使用前可以转动连接端头96而带动弹簧93产生扭曲内应力，并且通过锁定螺杆97固定在底盖3上，同时两个敲击头86与震动外壳2内表面之间抵压接触，使得敲击头86和震动外壳2保持相对静止，而在主动齿轮7转动过程中使得从动齿轮82转动时，会带动敲击头86收缩再撞击抵压到套管1内表面，进而实现在敲击头86收缩在伸出的这个短暂的过程中借助弹簧93内存储的扭曲内应力带动震动发生结构8整体小幅度转动，进而实现在敲击头86收缩撞击震动外壳2内表面过程中可以自行进行旋转，进而保证该振动棒可以进行全方面震动紧实效果，保证了混凝土成型后的强度。
请参阅图2和图3所示的一种便携式无刷电机振动棒，包括底盖3，所述底盖3的一端通过转轴与震动外壳2的底部活动密封连接，所述底盖3的中部开设有贯穿设置的螺纹槽；
在本实施例中，需要说明的是，当需要使用振动棒时，会将弹簧93扭转产生应力后，利用锁定螺杆97将其底端固定在底盖3中部开设的螺纹槽上，这样在震动发生结构8进行旋转时，可以保证套壳91正常带动震动发生结构8旋转进行全方位的敲击，进而保证了该振动棒的振捣效果。
请参阅图3和图5所示的一种便携式无刷电机振动棒，包括内环轨4，所述内环轨4上开设的环轨轨槽截面为半圆形，所述边块81的下表面外环均匀设置有多个滚珠，且该滚珠活动设在内环轨4的轨槽中，所述边块81的外表面与套管1的内表面不接触；
在本实施例中，需要说明的是，当在转动驱动结构9产生的旋转扭力作用下带动震动发生结构8旋转时，通过滚珠与内环轨4的设置大大降低震动发生结构8与内环轨4之间的摩擦力，进而保证震动发生结构8可以非常顺畅地进行快速的间歇性转动，保证了该振动棒的振捣效果的全面性。
请参阅图3、图4、图5和图6所示的一种便携式无刷电机振动棒，包括震动发生结构8，所述震动发生结构8包含两个边块81，两个所述边块81的相对面的中部活动安装有从动齿轮82，且在所述从动齿轮82的一侧位于边块81侧面固定安装有定位扣83，两个所述从动齿轮82的相对面上活动安装有第一连杆84，所述第一连杆84远离从动齿轮82的一端活动安装有第二连杆85，所述第二连杆85的端部固定安装有敲击头86；
在本实施例中，需要说明的是，两个所述边块81与底座5的两端固定连接，所述从动齿轮82与主动齿轮7垂直设置且从动齿轮82与主动齿轮7啮合连接，所述第一连杆84是偏圆心活动安装在从动齿轮82的表面，所述第二连杆85穿过定位扣83内活动连接，所述敲击头86的外表面设置有橡胶层垫，且所述第二连杆85的形状与震动外壳2内表面的形状相契合，所述震动外壳2内表面为粗糙设置，这样在主动齿轮7的转动作用下会带动两个从动齿轮82转动，进而带动第一连杆84产生不断的往复运动，第一连杆84的往复运动会带动第二连杆85在定位扣83的限制作用下横向不断做往复运动，从而使得敲击头86不断撞击震动外壳2的内表面，并且由于敲击头86外表面的橡胶层垫设置以及震动外壳2内表面的粗糙结构设置使得两者之间在相互抵压接触时可以产生强大的摩擦力保证两者之间相对静止，而在敲击头86收缩过程中脱离与震动外壳2内表面接触时利用弹簧93使得震动发生结构8整体进行短暂的旋转，直到敲击头86重新抵触到震动外壳2内表面停止转动，这样能够保证震动发生结构8可以自动进行转动以达到全面振捣的效果，进而保证混凝土后期成型的质量可靠性。
请参阅图5、图7和图8所示的一种便携式无刷电机振动棒，包括转动驱动结构9，所述转动驱动结构9包含套壳91，所述套壳91的内部活动安装有内杆92，所述内杆92和套壳91的内部之间固定设置有弹簧93，所述套壳91的底端活动安装有连接螺纹环94，所述连接螺纹环94的底端固定安装有转动把手95，所述内杆92的底端固定安装有连接端头96，所述连接端头96的底端活动连接有锁定螺杆97；
在本实施例中，需要说明的是，所述套壳91的顶端与底座5的底端固定连接，所述套壳91的内部以及内杆92位于套壳91内部的底端部分均设置有挡块，所述弹簧93的两端在套壳91和内杆92上设置的挡块之间卡接设置，所述连接端头96的底端中部设置有螺纹槽，且该螺纹槽与底盖3中部螺纹槽的总高度小于锁定螺杆97的有螺纹部分的杆的高度，且所述连接端头96底部的螺纹槽与连接端头96内部之间可伸缩但不可旋转活动设置，所述震动外壳2的内部位于连接螺纹环94所在位置设置有支撑圆环，且该圆环的中部设置有与连接螺纹环94契合的内螺纹，所述转动把手95的外径小于连接螺纹环94的外径，这样由于挡块的设置配合锁定螺杆97的定位效果，使得弹簧93内存储的扭曲应力在进行释放时只会带动套壳91转动，进而带动震动发生结构8转动，从而保证了敲击头86在撞击震动外壳2内表面时不发生转动，而在敲击头86收缩时发生旋转，保证了该振动棒的全面振捣效果，并且该振动棒内部的结构与震动外壳2之间的连接仅通过连接螺纹环94进行固定，所以在需要进行拆卸时，只要将连接螺纹环94从圆环上取下，并且将套管1和震动外壳2以及软轴10和连接转轴6之间断开连接即可将震动外壳2内部除了内环轨4之外的所有结构全部提出而完成装置的拆分，保证了该振动棒在检修或者更换时的便捷性。
工作原理，使用前，将底部的底盖3关闭，然后将锁定螺杆97拧入到底盖3中部的螺纹槽中，并且直到锁定螺杆97的顶端完全拧入到连接端头96底部的螺纹槽中，并且继续拧锁定螺杆97，此时通过连接端头96的转动带动内杆92转动，进而带动套壳91内部的弹簧93发生扭转，弹簧93扭转后内部存储有扭转力，然后将震动外壳2插入到浇筑的混凝土浆中，启动无刷电机，电机带动软轴10转动，软轴10则带动连接转轴6转动，连接转轴6带动主动齿轮7转动，主动齿轮7带动两个从动齿轮82转动，从动齿轮82则带动第一连杆84绕轴偏心旋转，进而带动第二连杆85和敲击头86快速地伸缩移动，此伸缩过程中，当敲击头86伸出与震动外壳2内表面抵触接触时，敲击头86不与震动外壳2内表面产生相对移动，而当敲击头86收缩时，在弹簧93内存储的扭转力作用下，会使得底座5转动，进而带动震动发生结构8整体在敲击头86收缩过程中快速的转动，直到敲击头86重新与震动外壳2内表面抵触接触停止旋转，这样会使得震动发生结构8在伸出敲击的过程中自动配合转动，从而使得该振动棒能够更加全面地进行振捣。
