Abstract
The utility model provides an elevator hoistway horizontal protection device which comprises an upper protection net rack and a bottom support net rack, an upper protection plate is arranged on the top of the upper protection net rack, side protection net racks are hinged to the four sides of the upper protection net rack respectively, side protection plates are arranged on the side protection net racks, telescopic mechanisms are arranged on the four sides of the bottom support net rack respectively, and the bottom support net rack is hinged to the bottom support net rack. The telescopic mechanisms are in one-to-one correspondence with the side protection net frames, anchoring grooves allowing the side protection net frames to be inserted therein are formed in the tops of the telescopic mechanisms, and the ends, away from the upper protection net frame, of the side protection net frames are inserted into the anchoring grooves of the corresponding telescopic mechanisms. The elevator shaft horizontal protection device can solve the problems existing in existing elevator shaft horizontal protection measures mentioned in the background technology.
