Elevator shaft mouth protection device for construction site

Abstract

The invention discloses an elevator shaft mouth protection device for a construction site. The elevator shaft mouth protection device comprises a fixing plate and further comprises a fixing frame, a door body and rolling wheels. The fixing frame is slidably connected to the fixing plate, and the rolling wheels are rotatably connected to the lower surface of a bottom plate of the fixing frame and make contact with the fixing plate. The door body is rotatably connected to the bottom of the fixed frame, and protective guards are fixedly connected to the inner side walls of the door body and the fixing frame. According to the elevator shaft mouth protection device, workers can conveniently enter and exit an elevator, the danger caused by the fact that the workers forget to close the door body when entering and exiting the elevator is avoided, meanwhile, the workers can conveniently carry large objects into and out of the elevator, and convenience is brought to the workers.

Description

technical field [0001] The invention relates to an elevator wellhead protection device, in particular to an elevator wellhead protection device for a construction site. Background technique [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 with the tower crane on the construction site. The load capacity is 1-3 tons, and the running speed is 1-63M / min. The construction principle and characteristics of the construction elevator: In order to meet the needs of inclined building construction such as bridges and chimneys, the construction elevator installs the guide rail frame obliquely according to the shape of the building, while the cage remains horizontal and runs up and down along the inclined guide rail frame. [0003] However, the door...

[0003] However, the door body in the existing elevator wellhead protection device for construction sites is generally connected with the building wall through a bolt. If the staff forgets to close the door body because they are in a hurry to leave the elevator, the elevator wellhead will be in an open state. , which can easily lead to accidents, making it difficult to guarantee the personal safety of the staff. At the same time, when the staff is carrying large items, such as carts, it is difficult to completely open the elevator shaft, which brings inconvenience to the staff.
