Pushing device for assembling subway overline fully-prefabricated bridge
The pushing device comprises a bearing seat, a first sliding groove, a first sliding seat and a longitudinal oil cylinder, the first sliding groove is formed in the bearing seat, the first sliding seat is installed in the first sliding groove, the longitudinal oil cylinder is arranged on one side wall of the first sliding seat, and the longitudinal oil cylinder is arranged on the other side wall of the first sliding seat. Bearing boxes are arranged on the two sides of the upper end of the first sliding base, and second sliding grooves are formed in the bearing boxes. The device has the beneficial effects that by arranging the oil storage tank, the lubricating oil pipe, the electromagnetic valve and the pressurizing pump, in the pushing process, the electromagnetic valve opens the lubricating oil pipe, the pressurizing pump pressurizes lubricating oil in the oil storage tank, and then the lubricating oil flows into a gap between the sliding groove and the sliding seat through the lubricating oil pipe to lubricate the gap between the sliding groove and the sliding seat; the friction force between the sliding seat and the sliding groove is reduced, the situation that dust falls into the sliding groove to affect the smoothness and the moving speed of the sliding seat in the moving process is avoided, and the practicability and the pushing efficiency of the device are improved.
本申请公开了一种地铁跨线全预制桥梁拼装用顶推装置，包括承载座、滑槽一、滑座一和纵向油缸，所述承载座内设置有所述滑槽一，所述滑槽一内安装有所述滑座一，所述滑座一一侧壁上设置有所述纵向油缸，所述滑座一上端两侧均设置有承载箱，所述承载箱内设置有滑槽二。有益效果在于：通过设置储油罐、润滑油管、电磁阀和加压泵，在顶推过程过程中，电磁阀将润滑油管打开，加压泵对储油罐内的润滑油进行加压，进而使其通过润滑油管流入到滑槽与滑座的间隙中，对两者之间进行润滑，不仅减小两者之间的摩擦力，而且避免因灰尘落在滑槽内而影响滑座移动时的顺畅性以及移动速率，提高装置实用性和顶推效率。
