The invention relates to the technical field of hoists, in particular to a construction hoist cage door and a construction hoist cage. Two first motors are connected with a door frame, two first gears are connected with the output ends of the two first motors, two racks are connected with a door plate, two limiting plates are connected with the door frame, and two connecting plates are connected with the door plate. Two outer cylinders are connected with the two connecting plates, two buffer springs are connected with the two outer cylinders, two first limiting blocks are connected with the two buffer springs, two inner cylinders are connected with the two first limiting blocks, and when the connecting plates on the door plate make contact with the limiting blocks on the door frame, the maximum value that the door plate slides out of the door frame is achieved. The buffer springs between the limiting plates and the connecting plates buffer the pressure applied to the limiting plates when the motors excessively drive the racks to drive the connecting plates, the limiting plates are protected, and the problem that the door and the racks are separated from the door frame due to the fact that the motors of the construction hoist cage door drive the first gears to excessively rotate is solved.
Description
technical field [0001] The invention relates to the technical field of elevators, in particular to a construction elevator cage door and a construction elevator cage. Background technique [0002] As a vertical transportation tool for materials during construction, construction elevators are widely used, and cages are an important part of construction elevators; [0003] The cage door of the existing construction elevator drives the rack through the first gear at the output end of the motor on the door frame to drive the door panel to go up and down so as to realize the process of opening and closing the door; [0004] However, when the motor drives the first gear to over-rotate, the door panel and rack will be separated from the door frame. Contents of the invention [0005] The purpose of the present invention is to provide a construction elevator cage door and a construction elevator cage, aiming to solve the problem that the motor of the construction elevator cage doo...
