The invention discloses a pier column lifting device for road and bridge construction and a lifting method of the pier column lifting device, and belongs to the technical field of road and bridge construction. Comprising a bearing unit and a positioning clamping unit, when a first clamping mechanism makes contact with a second clamping mechanism, an upper assembling block and a lower assembling block are directly connected in series through a rope, and a pier column carrying piece is clamped through a thermal expansion attaching clamping piece and the inner end face of a second assembling frame; the side end face of the thermal expansion fitting clamping piece is a component made of a metal material, one end of the thermal expansion fitting clamping piece is heated through an external motor, so that the temperature of the outer surface of the thermal expansion fitting clamping piece rises to a rated height, and thermal expansion fitting is performed on the inner end face of the second assembly frame through heat generated by the surface of the thermal expansion fitting clamping piece; and the pier column carrying piece clamped between the first clamping mechanism and the second clamping mechanism is subjected to thermal expansion fitting clamping.
本发明公开了一种路桥建筑用墩柱起吊装置及其起吊方法,属于路桥建筑技术领域。包括承载单元和定位夹持单元,当第一夹持机构与第二夹持机构二者之间互相接触时,上组装块与下组装块直接进行绳索串联,通过热胀贴合夹持片与第二组装架内端面的对墩柱携带件进行夹持,且因热胀贴合夹持片的侧端面为金属材质制成的构件,通过外接电机向热胀贴合夹持片的一端进行加热处理,使其外表面的温度上升至一个额定高度,通过其表面产生的热量对第二组装架的内端面进行热胀贴合,至使夹持在第一夹持机构与第二夹持机构之间的墩柱携带件进行热胀贴合夹持。
