The invention discloses an automatic ceiling lifting mechanism for a paver in the technical field of paver transportation machinery, and aims to solve the problem of difficult transportation caused by overhigh height of the paver in the transportation process in the prior art, and the automatic ceiling lifting mechanism comprises a middle connecting frame and a telescopic oil cylinder, the telescopic oil cylinder is arranged in the middle connecting frame in a penetrating mode and connected with the peripheral side portions of the ceiling stand columns, the tail end portions of the ceiling stand columns are rotationally connected with the middle connecting frame, the two-hand journal sticking shafts are arranged above the ceiling stand columns in a penetrating mode, and the end portions of the two-hand journal sticking shafts are provided with zipper assemblies; the zipper assembly can control the freedom degree of the two-hand journal sticking shaft through opening and closing, so that the two-hand journal sticking shaft is in a fastened state or a loosened state. When the two-hand journal sticking is in a loose state, the telescopic oil cylinder can drive the ceiling stand column to rotate around the end of the telescopic oil cylinder till the ceiling stand column reaches the horizontal position. The height of the paver can be reduced during transportation, the transportation operation is convenient, the operation is simple, and the use experience of a user is greatly improved.

本发明公开了一种摊铺机运输机械技术领域的摊铺机用顶棚自动升降机构，旨在解决现有技术中摊铺机在运输过程中高度过高，导致运输困难的问题，其包括中间连接架和伸缩油缸，伸缩油缸穿设于中间连接架内部与顶棚立柱外周侧部连接，顶棚立柱末端端部与中间连接架转动连接，且其上方穿设有双手抱轴，双手抱轴的端部均设有拉锁组件；拉锁组件能够通过开合控制所述双手抱轴的自由度，使得双手抱轴处于紧固状态或松动状态；当双手抱轴处于松动状态时，伸缩油缸能够带动顶棚立柱绕其端部转动，直至顶棚立柱到达水平位置。本发明可以在运输时降低摊铺机的高度，方便运输操作，操作简单，极大提高了用户使用体验。
