摘要： The present invention provides a rope climbing elevator system (30) comprising: an elevator car (110); host upper diverter pulleys (120a, 120b); a tensioner (160); host lower diverter pulleys (150a, 150b); ropes (130a, 130b); and a counter-rotating paired drive pulley (141). A ratio of linear speed of the first drive pulley (141a) and the second drive pulley (141b) to movement speed of the car (110) is about X:1 in the climbing process, wherein X is larger than or equal to 2. The elevator system (30) can achieve a ratio of a linear rotation speed of a drive motor to a movement speed of an elevator car, larger than or equal to about 2:1, can lower the torque requirement for the drive motor, decrease the weight of the drive motor, and reduce the cost of the drive motor.

摘要： A mobile car sheave shield comprises a static shield part 2 sleeved on a car sheave 1, wherein an opening is formed on upper of the static shield part; a dynamic shield part is arranged on the opening; the dynamic shield part comprises a shield bracket 3; an inner side mobile shield 4 and an outer side mobile shield 5 which are synchronously connected are respectively arranged on two sides of a central axis of the shield bracket from inside to outside; the outer side mobile shield and the inner side mobile shield are slidingly connected on the shield bracket. The present invention has the advantages that: by combining the static shield part and the dynamic shield part, the dynamic shield part is moved by the traction rope, to realize mobile protection of the shield, thus offering a clearance constantly meeting safety requirement and guaranteeing safety of a car top worker.
