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.
本发明涉及升降机技术领域,具体涉及一种施工升降机吊笼门及施工升降机吊笼,通过两个第一电机与门框连接,两个第一齿轮与两个第一电机输出端连接,两个齿条与门板连接,两个限位板与门框连接,两个连接板与门板连接,两个外筒与两个连接板连接,两个缓冲弹簧与两个外筒连接,两个第一限位块与两个缓冲弹簧连接,两个内筒与两个第一限位块连接,当门板上的连接板与门框上的限位块接触时为门板滑出门框的最大值,限位板与连接板之间的缓冲弹簧对电机过度驱动齿条带动连接板对限位板施加的压力进行缓冲,对限位板提供保护,解决了施工升降机吊笼门的电机带动第一齿轮过度旋转会导致门和齿条与门框分离的问题。
