The invention provides a road surface lifting beam, and relates to the field of road surface winding and unwinding. The road surface lifting beam comprises a U-shaped lifting beam, a driving motor structure, a heightening frame structure, a plug-in type bearing seat structure and a winding drum. The driving motor structure is fixedly connected to the U-shaped lifting beam, and the heightening frame structure is inserted into the U-shaped lifting beam. When the height of the winding drum is increased, double-pin connection at the lower end of the plug-in type bearing seat structure is removed, the winding drum and the plug-in type bearing seat structure are lifted, the plug-in type bearing seat structure is pulled out along the U-shaped lifting beam, the heightening frame structure is inserted into the U-shaped lifting beam, the lower side of the heightening frame structure is connected through double pins, and the plug-in type bearing seat structure falls down again. The lower end of the plug-in type bearing seat structure is connected with the upper side of the heightening frame structure through double pins, so that the driving motor structure is meshed with the winding drum again, and the maximum lifting height of the winding drum continues to be increased by increasing or decreasing the heightening frame structure in the U-shaped lifting beam.
本申请提供一种路面举升梁,涉及路面卷绕收放领域。路面举升梁包括:U形举升梁、驱动马达结构、增高架结构、插接式轴承座结构和卷筒。所述驱动马达结构固定连接于所述U形举升梁上,所述增高架结构插入所述U形举升梁内部。增加卷筒高度时,解除插接式轴承座结构下端的双销连接,吊起卷筒和插接式轴承座结构,插接式轴承座结构沿U形举升梁抽出,将增高架结构插入U形举升梁内,增高架结构下侧通过双销连接,重新落下插接式轴承座结构,插接式轴承座结构下端和增高架结构上侧通过双销连接,使驱动马达结构重新啮合于卷筒,通过在U形举升梁内增减增高架结构,以此继续提高卷筒的最大升高高度。
