The invention relates to a corridor
elevator and a safety protection device thereof. The corridor
elevator comprises a guide device, a driving
system, a roller
assembly, a carrier platform and a baffle. The guiding device is fixed on the corridor through the upper end plate and the lower end plate on the guiding device, the guiding device is of a truss structure composed of the upper guide rail, the lower guide rail and the supporting piece, the overall rigidity is improved, the middle position of the guide rail is not fixed to the step through a bolt, damage to the corridor step is reduced, and the field installation efficiency is improved. The speed
reducer of the driving
system is preferably fixed to the lower end plate, the motor is arranged above the speed
reducer, the seat plate of the carrier platform is arranged above the guiding device, the transverse width of the corridor
elevator is reduced, and the overall arrangement space is saved. A transmission chain connecting plate of the roller
assembly is connected with a transmission chain of the driving
system, and a roller of the roller
assembly rotates in a guide rail roller groove of the guide device. The platform connecting plate of the carrier platform is fixed to the roller fixing plate of the roller assembly and moves up and down along the guide rail roller groove along with the rolling assembly. The speed
reducer is preferably a
turbine speed reducer, and when accidental power failure occurs, due to the fact that the
turbine speed reducer has a self-locking function, the carrier platform cannot move accidentally. The roller assembly is provided with a shoe block locking assembly, when the accelerated speed of accidental descending of the carrier platform exceeds a
limit value, the shoe block locking assembly can prevent the carrier platform from accelerating descending, and personnel or objects are prevented from being damaged. The rolling wheel assembly is provided with an anti-toppling plate, when the rolling wheels fall off accidentally, the anti-toppling plate prevents the rolling wheel assembly and the carrier platform from toppling over, and personnel or objects are prevented from being damaged.
