The invention discloses a span-adjustable beam lifter which comprises a cross beam. An adjusting structure is arranged on one side face of the cross beam, a fixing block is fixedly connected to the lower surface of the adjusting structure, a supporting frame is fixedly connected to the lower surface of the fixing block, and a box body is fixedly connected to the lower surface of the supporting frame. A transmission structure is arranged in the box body, and the adjusting structure comprises a sliding clamping ring, a rack, a limiting box, a gear, a screw rod and a first-stage servo motor. According to the span-adjustable beam lifter, through cooperation of rolling wheels and the transmission structure, the span-adjustable beam lifter has the effects of being capable of moving transverselyand vertically, so that the effect that movement is convenient is achieved; and through cooperative arrangement of the adjusting structure and the cross beam, in the using process, the supporting frame can be indirectly driven to move through the first-stage servo motor, then the effect of improving the applicability is achieved, and the purpose of adjusting the span is achieved.

    本发明公开了一种跨度可调整的提梁机,包括横梁,横梁的一侧面设置有调节结构,所述调节结构的下表面固定连接有固定块,所述固定块的固定块的下表面固定连接有支撑框架,所述支撑框架的下表面固定连接有箱体,所述箱体的内部设置有传动结构,所述调节结构包括滑动卡环、齿条、限位箱、齿轮、螺杆和一级伺服电机。该跨度可调整的提梁机,通过滚轮、传动结构的配合,使该跨度可调整的提梁机具备了既可以横向移动,也可以竖向移动的效果,从而起到了便于移动的作用,通过调节结构和横梁的配合设置,在使用的过程中可以通过一级伺服电机间接的带动支撑框架移动,进而起到了提高适用性的作用,达到了可调节跨度的目的。
