LI DALI / WANG CHUNGE / SHI JIANGUO / TANG WEIDONG / ZHOU ZHENGGANG

The invention provides a liftable shaped hoistway protection device which comprises a lifter fixing platform and a protection platform and is characterized in that a motor is arranged above the lifter fixing platform, a gear box is arranged on one side of the motor, a steel cable fixing pulley is arranged below the gear box, and a steel cable is arranged below the steel cable fixing pulley. The protection platform is arranged below the elevator fixing platform, hoisting blocks are arranged on the two sides of the protection platform and connected with the steel cables, a fixing plate is arranged on one side of the protection platform, damping fixing blocks are arranged on the other side of the protection platform, and connecting blocks are arranged below the protection platform and on the side close to the damping fixing blocks. And a supporting rod is arranged below the connecting block. The protective platform has the advantages that the protective platform can stably ascend and descend by arranging the gear box and the steel cable fixing pulleys, the protective platform can be more conveniently fixed and reinforced by using the two fixing plates and the damping fixing blocks, the production cost is reduced by using the net-shaped supporting plate, and meanwhile the structural strength is enhanced.

本发明提供的一种可提升式定型化井道防护装，包括升降机固定平台和防护平台，其特征在于，所述升降机固定平台的上方设有电机，所述电机的一侧设有齿轮箱，所述齿轮箱的下方设有钢缆固定滑轮，所述防护平台设于升降机固定平台的下方，所述防护平台的两侧设有吊装块，并与钢缆相连，所述防护平台的一侧设有固定板，另一侧设有减震固定块，所述防护平台的下方和靠近减震固定块的一侧设有连接块，所述连接块的下方设有支撑杆。本发明的优点：通过设置齿轮箱与钢缆固定滑轮可以使防护平台进行平稳升降，通过使用两个固定板与减震固定块可以更方便固定防护平台，同时加固，通过使用网状支撑板减少了生产成本，同时加强了结构强度。
