The hydraulic cylinder jacking device comprises a jacking oil cylinder, a scraping lantern ring is installed at the top end of the jacking oil cylinder, an oil cavity is formed in the jacking oil cylinder, a piston is installed in the center of the oil cavity, four sets of hydraulic rods are connected to the top end of the piston, and the top end of the hydraulic rod is connected with a hydraulic cylinder. And the hydraulic rod penetrates through the scraping lantern ring and extends to the outer side of the hydraulic cylinder. In addition, through the arrangement of a hydraulic rod and a piston, in the using process, gas in the jacking oil cylinder can be extruded through the piston, so that gas flow can flow through a heat dissipation pipe, heat dissipation is conducted on the piston, and residual gas flow can be discharged through a guide pipe, a main pipe and a ventilation pipe; and if the piston moves downwards, the space in the jacking oil cylinder is increased, external air is sucked into the jacking oil cylinder through the ventilation pipe, the main pipe, the guide pipe and the heat dissipation pipe, heat dissipation is further conducted on the piston, and the heat dissipation effect is improved.
本发明公开了一种便于散热的液压缸顶升装置,涉及液压缸领域,包括顶升油缸,所述顶升油缸的顶端安装有刮除套环,所述顶升油缸的内部开设有油腔,所述油腔的中央位置安装有活塞,所述活塞的顶端连接有四组液压杆,且液压杆贯穿刮除套环延伸至液压缸外侧。本发明还通过设置的液压杆以及活塞,能够在使用过程中,通过活塞对顶升油缸内部的气体进行挤压,使得气流会通过散热管进行流动,从而对活塞进行散热,剩余的气流会通过导向管、总管以及换气管排出,当液压杆回位时,则活塞向下移动增加顶升油缸内的空间,将外界空气通过换气管、总管、导向管、散热管吸入到顶升油缸内,从而进一步对活塞进行散热,提高散热效果。
