The cover shifting device comprises stand columns, a lifting seat, a rotating seat, a shifting fork assembly and a tension adjusting assembly, the stand columns are perpendicularly installed on the two sides of a rail, the rotating seat is installed at the top ends of the stand columns, the lifting seat is installed on the rotating seat, and the shifting fork assembly is hinged to the lifting seat; the lifting seat drives the shifting fork assembly to vertically ascend and descend on the stand column and is used for blocking the telescopic ceiling shifting column so as to open or close the telescopic ceiling. The lock catch piece is arranged on the shifting fork rod of the cover shifting device, and the shifting fork rod is locked through the lock catch piece. When the cover shifting force of the shifting fork rod exceeds a set value, the locking piece is unlocked, so that the shifting fork rod can deflect and is separated from the telescopic ceiling shifting column, and the shifting fork rod or the telescopic ceiling shifting column is prevented from being damaged. And meanwhile, a tension adjusting assembly is arranged to control the cap shifting force of the cap shifting device.

    本发明公开了一种敞口车伸缩顶棚拨盖力控制方法及拨盖装置,包括:立柱、升降座、旋转座、拨叉组件及张力调节组件,立柱垂直安装在铁轨两侧,旋转座安装在立柱顶端,升降座安装在旋转座上,拨叉组件铰接在升降座上,升降座带动拨叉组件在立柱上垂向升降,用来阻挡伸缩顶棚拨柱,以打开或关闭伸缩顶棚。通过在拨盖装置的拨叉杆上设置锁扣件的方式,利用锁扣件锁定拨叉杆。当拨叉杆的拨盖力超过设定值时,锁扣件解锁,使得拨叉杆能够偏转,从而与伸缩顶棚拨柱脱离,避免拨叉杆或伸缩顶棚拨柱被损坏。同时设置有张力调节组件,以控制拨盖装置的拨盖力。
