Problems solved by technology

This method of installing the door is cumbersome, and the opening and closing of the platform door must be completed by the people in the elevator cage, especially after the people in the elevator cage are gone, the elevator driver must complete the closing of the platform door, which affects work efficiency
Because the workers are busy at work or it is cumbersome to close the door with a steel bar bolt, they will be negligent in locking the bolt, leaving a safety hazard

Abstract

The invention discloses a construction elevator protective door capable of automatically closing. The protective door comprises two steel tube stand column fixed onto a construction elevator. A steel fence door body capable of opening and closing is arranged between two steel tube stand columns. A rotating mechanism capable of driving the steel fence door body to open and then automatically back to close is arranged between one of the two steel tube stand columns and the steel fence door body and connected with the latter. The rotating mechanism comprises a locating shaft mounted between one of the steel tube stand column and the steel fence door body. The locating shaft is sleeved with a sleeve. The sleeve is connected with the steel fence door body and capable of rotating relative to the locating shaft. Two ends of the sleeve are respectively fixed to the steel tube stand column. A spiral curve notch is formed on the outer wall of the sleeve along the axis of the sleeve. A locking device capable of opening and closing the steel fence door body is arranged between the steel fence door body and the other steel tube stand column. The open steel fence door body can automatically close by means of the turning force produced by torsional deformation of the sleeve during opening.

Description

technical field [0001] The patent of the present invention relates to a construction machine, in particular to a protective door of a construction elevator that can be automatically closed during construction. technical background [0002] The construction elevator is also called the construction elevator for construction. It is a manned and cargo-carrying construction machine often used in construction. Because of its unique box structure, it is comfortable and safe to ride. The construction elevator is usually used in conjunction with the tower crane on the construction site. With the advancement and development of science and technology, there are more and more high-rise buildings, construction elevators have also become a common vertical transportation tool in the construction industry, and are widely used in construction such as industrial and civil buildings, bridge construction, underground construction, large chimney construction and It is suitable for vertical trans...
