Abstract

一种可连续调节倾斜高度或角度的斜面支架,其包括斜面部分和可升降支架部分。其中升降支架部分由中部共轴的剪叉式支撑杆A(4)和支撑杆B(3)构成,通过螺杆的推动使两根支撑杆A/B(4、3)绕轴转动,并带动上导轨(2)升降运动,上导轨(2)再通过转轴或铰链和斜面板(10)的顶端连接,从而在上导轨(2)连续升降时带动斜面板(10)的高度或角度也跟着连续变化。该斜面支架只采用两组转动臂,稳固性好,升降范围大。

Description

可连续调节倾斜高度或角度的斜面支架 技术领域
本发明渉及一种可连续调节倾斜高度或角度的斜面支架,属于台阶斜坡垫,马路牙子斜坡垫,登车桥斜坡支架,太阳能斜面支架等领域。
背景技术
目前,开车上马路边上的台阶或从台阶上下来时,人们常会使用斜坡垫,这种斜坡垫一般高度是固定的,而现实中人们会遇到各种高度不同的台阶,所以固定高度的斜坡垫是不适用于不同地段不同高度的地况。现在还有一种剪式千斤顶斜面支架(申请号:201310097208 .5),虽可连续调节倾斜高度且承重力强,但是千斤顶式的是点支撑,平衡性及稳固性差,需至少二个以上的点位支撑才稳,而且通常一个千斤顶有4个转动支撑臂,二个千斤顶需要8个转动臂,所以很复杂,不实用;另外,千斤顶的转动臂偏短,不适合升降范围大的应用场合。
技术问题
为了解决应对不同高度台阶的情况,需用一种可连续调节倾斜高度或角度的斜面支架,且承重强,升降范围大。
技术解决方案
本发明所采用的技术方案是:采用剪叉式升降机的升降原理,使用一对(两组)剪叉式转动支撑杆(支撑臂),剪式转动支撑杆的中部装有公共转动轴,两根同方向的支撑杆A的一端和下导轨通过转轴连接固定在下导轨的一端,另一端通过转轴连接滑轮或滑块,其滑轮或滑块可在上导轨上滚动或滑动;两根同方向的支撑杆B的一端(和A的固定转轴端同侧)和上导轨通过转轴连接固定在上导轨的一端,另一端通过转轴连接滑轮或滑块,其滑轮或滑块可在下导轨上滚动或滑动;支撑杆B连接的滑轮或滑块上有螺母孔,有螺杆和该螺母孔及下导轨上的固定转动支座孔(螺杆只在孔内转动而无轴向位移)或螺纹孔机械连接,通过转动螺杆可推动滑轮或滑块在下导轨上移动,也就连续性的推动支撑杆B在导轨上移动,这样支撑杆B和支撑杆A就会绕公共轴转动,与此同时两根支撑杆上的上导轨就会升降运动,上导轨再通过转轴或铰链和斜面板的一侧的顶端连接,这样,在上导轨连续升降时,斜面高度或角度也跟着连续变化。
进一步的,螺杆的转动部分可加入电机驱动,通过控制电机的正反转动来控制调节斜面支架的倾斜高度或角度。
进一步的,加入遥控装置,来控制电机的正反转动。
进一步的,上导轨可采用圆柱结构,该圆柱直接作为斜面板或铰链的转动轴。
进一步的,斜面板采用弧度不大的“凸”形或弧形结构,增加强度。
进一步的,支架上面加上用于定位的指示灯或警示灯,引导斜面板的方位,或起警示作用。
进一步的,两组支撑杆是嵌入结构,一组支撑杆嵌入在另一组支撑杆中间,这样结构更紧凑,支撑的上导轨也便于在同一中心线上。
进一步的,把斜面板换成圆弧形且凹行的面结构,可用于阻止车轮的滚动,或阻止其它圆状物的滚动,可叫阻滚器,也可叫阻车器。
进一步的,与支撑杆的移动端相连接的滑轮或滑块,其在导轨上的移动部分,可采用和轨道面贴合的面与面接触的结构,移动时靠滑动,而不是圆与平面或圆柱与平面的点接触或线接触结构,以增加承受力,为此,要通过带转轴的滑动块作中间连接。
有益效果
本方案只需采用两个转动臂,比千斤顶式的简单很多,因为支撑杆更长,使的升降范围更大。方案中的螺杆也可以采用液压推杆或机械卡位等方式来调节。

本发明的最佳实施方式
图1是本发明的一个的示意图,图1中的3支撑杆B和4支撑杆A都有左右两个支撑片且两个支撑片通过横相结构连接在一起,3支撑杆B是嵌入在4支撑杆A的两个支撑片中间的,两支撑杆的中部通过公共转动轴连接。4支撑杆A的一端和1下导轨座通过转轴连接,4支撑杆A的另一端通过转轴和7上滑动块连接,7上滑动块可在2上导轨上滑动或移动。3支撑杆B的一端通过转轴和8上固定块连接,8上固定块是固定在2上导轨上的,3支撑杆B的另一端通过转轴和5下滑动块连接,5下滑动块可以在1下导轨上面的15承压板上面位移滑动。5下滑动块上有螺母孔,该螺母孔上有螺杆穿过,螺杆的转动由与之连接一体的11手柄控制。11手柄与螺杆的中间部位有6圆盘,6圆盘处在9后阻挡板和12前阻挡板的中间,只能在中间转动而不会有轴向位移。这样,11手柄在转动时,带动螺杆转动,通过转动可使5下滑动块在15承压板上面位移滑动,通过5下滑动块上转轴的推动作用,驱动3支撑杆B的下端移动,3支撑杆B再通过支撑杆的公共轴驱动4支撑杆A也跟着移动,这样就带动2上导轨产生了升或降的运动,2上导轨是圆轴结构,装置在10斜面板的两个轴孔中,这样,2上导轨在升降运动时,通过转轴使 10斜面板的上端升降运动,这样就实现了倾斜高度或角度的调节,因为11手柄上的螺杆所驱动的位移是连续的,所以使的最后相应升降的10斜面板的倾斜高度或角度也是在一范围内连续可调节的。为了使螺杆的端头固定,用16轴支撑座上的孔支撑螺杆的端头部位。为了不使10斜面板的下端自由活动并形成一个整体,在10斜面板的下端通个轴孔和13连接杆的一端连接,13连接杆的另一端和14底盘上的孔相机械连接,这样就形成一个整体结构。有些部件是焊接固定在1下导轨座上的,如9后阻挡板,12前阻挡板,16轴支撑座,15承压板。
另外,6圆盘在在9后阻挡板和12前阻挡板的中间转动的结构,也可改成螺杆在螺母孔里转动的结构,但是该段螺杆和螺母孔要做成反丝(反牙)结构,就是和5下滑动块上的螺母和其内的螺杆互为反丝(反牙)结构。
图2是为了把各部件的结构分的更清楚的一个简单拆分图。
图3是一个局部图,主要是为了把6圆盘,9后阻挡板,12前阻挡板,5下滑动块,16轴支撑座,11手柄,1下导轨座,15承压板,都画的更清楚一些。
