The hydraulic lifting platform with the self-locking structure is characterized in that a lifting platform body is installed at the top end of a shear type lifting frame, limiting sliding grooves are symmetrically formed in the left end and the right end of the lifting platform body, limiting pieces are slidably installed in the limiting sliding grooves, and stand columns are symmetrically fixed to the left side face and the right side face of a base; a door plate is installed between the two stand columns on the front side, the left end of the door plate is rotationally connected with the stand column on the left front side through a pin shaft, a locking mechanism is installed in the stand column on the right front side, the locking mechanism is arranged in the stand columns, a locking piece in the locking mechanism can lock the door plate, and a fixing piece can lock a limiting piece. When the door plate is in an open state, the fixing piece locks the limiting piece so that the lifting table can not ascend and descend, and when the lifting table is not located at the highest position, the locking piece can automatically lock the door plate so that the door plate can not be opened.

    本发明公开了一种具有自锁结构的液压升降台,所述剪式升降架的顶端安装有升降台,所述升降台左右两端对称开设有一个限位滑槽,所述限位滑槽内滑动安装有限位件,所述底座左右两侧面对称固定有一个立柱,前侧两根所述立柱之间安装有门板,所述门板的左端通过销轴与左前侧的立柱转动连接,右前侧所述立柱内部安装有锁紧机构,通过在立柱内部设置锁紧机构,锁紧机构中的锁紧件能够对门板进行锁定,固定件能够对限位件进行锁定,当门板处于开启状态时,固定件则会对限位件进行锁定,从而使得升降台无法升降,当升降台不处于最高处时,则锁紧件将会自动对门板进行锁定,使门板无法开启。
