A seamless telescopic gangway ladder comprises a fixed section and a movable section, the movable section is connected with the fixed section in a reciprocating sliding fit mode, a telescopic transmission device is arranged below the fixed section and the movable section and comprises a small transmission chain wheel set and a large transmission chain wheel set, and the small transmission chain wheel set is connected with the movable section and drives the movable section to slide in a reciprocating mode. The large transmission chain wheel set and the small transmission chain wheel set rotate synchronously in the reverse direction, one end of a conveying belt is fixed to the large transmission chain wheel set and drags the conveying belt to reciprocate, and the other end of the conveying belt bypasses the far end of the movable section to extend and is fixed to one end of the fixed section. In application, the conveying belt is arranged on the working face to form a whole, gaps and relative sliding of the movable section of the gangway ladder are covered, the conveying belt with the redundant length is dragged to the bottom to be hidden through synchronous reverse rotation of the large transmission chain wheel set, the problem of redundancy of the conveying belt caused by stretching is solved, meanwhile, the size is reduced, and cost is reduced. And potential safety hazards are reduced. Therefore, the safety of the design is high.
一种无缝伸缩式舷梯,包括固定段与活动段,活动段与固定段往复滑动配合连接,固定段与活动段的下方设有伸缩传动装置,伸缩传动装置包括小传动链轮组与大传动链轮组,小传动链轮组与活动段相连,驱动活动段往复滑动,大传动链轮组与小传动链轮组反向同步转动,大传动链轮组上固定有传送带的一端,并牵引其进行往复移动,另一端绕过活动段的远离端延伸,并固定于固定段的一端;在应用中,在工作面上设置有传送带,使其成为一个整体,遮盖了舷梯活动段的缝隙与相对滑动,并且通过大传动链轮组的同步反向转动,将多余长度的传送带牵引至底部隐藏,解决了伸缩带来的传送带冗余问题,同时减小了体积,减少了安全隐患。因此,本设计的安全性较高。
