The invention discloses an automobile roof unfolding device for transportation, which comprises a carriage. Two sides of the carriage are opened; the four corners of the bottom face of the inner wallof the carriage are provided with lower ends of screws through bearings respectively;the thread directions of the upper sides and the lower sides of the center lines of the screws are opposite;the upper ends of the screws are fixedly provided with lower ends of connecting shafts respectively, the upper ends of the connecting shafts are connected with bearings on the top face of the inner wall of the carriage, and threaded sleeves are installed on the upper sides and the lower sides of the screws. In the process of unfolding the roof, under match among the screws, the threaded sleeves, worm wheels, worms and other structures, when the side plate isunfolded, the thread sleeve can draw close to the middle of the screw along the screw, therefore, the included angle between the hydraulic cylinder and the carriage is continuously changed along with the unfolding of the side plate; after the included angle between the hydraulic cylinder and the carriage is correspondingly increased, more pressure borne by the hydraulic cylinder can be dispersed to the connecting point of the hydraulic cylinder and the threaded sleeve, the pressure borne by the hydraulic cylinder is correspondingly reduced, and therefore the hydraulic cylinder is protected, is not prone to bending and is prevented from being damaged.
一种交通运输用汽车顶棚展开装置,包括车厢,车厢的两侧开口,车厢内壁的底面四角分别轴承安装螺杆的下端,螺杆中心线上侧、下侧的螺纹方向相反,螺杆的上端分别固定安装连接轴的下端,连接轴的上端均与车厢的内壁顶面轴承连接,螺杆的上侧和下侧均螺纹安装螺套。本发明在顶棚展开的过程中,在螺杆,螺套,蜗轮,蜗杆等结构的配合下,当侧板展开时,螺套能够沿螺杆向螺杆的中间靠拢,从而使液压缸与车厢之间的夹角随侧板的展开不断发生变化,液压缸与车厢之间的夹角相应增加后,液压缸所受到的压力会更多的分散到液压缸与螺套的连接点处,使液压缸所承受的压力相应的减小,从而保护液压缸,使液压缸不易发生弯曲,避免损坏。
