The invention discloses a gantry type self-walking automatic folding and unfolding awning. The awning comprises a folding and unfolding mechanism installed on a carriage and awning cloth covering thefolding and unfolding mechanism. The folding and unfolding mechanism is driven by vertical plates symmetrically arranged on the left side and the right side. A driving chain wheel is arranged on the inner side of each vertical plate; the driving chain wheels on the left side and the right side are driven by the same power assembly, a driven chain wheel is arranged below each driving chain wheel, the driving chain wheels are connected with the corresponding driven chain wheels through chains, idler wheels are coaxially installed beside the driven chain wheels, the idler wheels are matched withrails in a rolling mode, and the rails are fixed to the outer side of the carriage. The folding and unfolding mechanism is driven in a gear and chain transmission self-walking mode, the structure is simple and compact, mounting and operation are easy, the production cost is low, the operation reliability is good, the movement synchronism of the left vertical plate and the right vertical plate is good, the clamping stagnation defect is not likely to happen, it is guaranteed that the awning cloth can be normally folded and unfolded all the time, safety is good, and the folding and unfolding mechanism is suitable for various trucks.

    本发明公开了一种龙门式自行走自动收展篷,包括在车厢上安装的收展机构以及覆盖在收展机构上的篷布,收展机构由左右两侧对称设置的立板带动,在每块立板的内侧均设有主动链轮,左右两边的主动链轮由同一个动力总成驱动,在每个主动链轮的下方均设置从动链轮,主动链轮通过链条与对应的从动链轮连接,在从动链轮的旁边同轴安装滚轮,该滚轮与轨道滚动配合,轨道固定于车厢的外侧。本发明采用齿轮+链传动的“自行走”形式来带动收展机构,结构简单、紧凑,安装操作容易,生产成本低,运转的可靠性好,并且左右两边立板运动的同步性好,不易产生卡滞的弊病,确保了篷布始终能正常收展,安全性好,适合于各种货车安装使用。
