The invention discloses an elevator car top maintenance safety protection device. The device comprises a protection net, a left hydraulic cylinder and a right hydraulic cylinder. Both the left hydraulic cylinder and the right hydraulic cylinder are fixed to the lower end of an elevator car, and the left and right ends of the elevator car are in sliding connection with a left sliding rail and a right sliding rail correspondingly. A PLC is fixed to the inner wall of the elevator car, and an output end of the PLC is electrically connected with input ends of the left hydraulic cylinder and the right hydraulic cylinder correspondingly. A left stop bar and a right stop bar are mounted on the left and right inner walls of the elevator car correspondingly. Third through holes are formed in the left and right ends of the elevator car correspondingly. An elevator car body is arranged on the elevator car, and the upper end of the elevator car body is fixedly connected with the protection net. A safety belt is arranged at the upper end of the elevator car body. According to the elevator car top maintenance safety protection device, by arranging the protection net, the left stop bar, the PLC, the right stop bar, the left hydraulic cylinder, the right hydraulic cylinder and the safety belt, the problems that a safety protection device is poor in protection effect, consequentially, safety accidents are prone to occurring, operation is difficult, and time and labor are consumed are solved.
Description
technical field [0001] The invention relates to the technical field of elevator car top inspection safety protection, in particular to an elevator car top inspection safety protection device. Background technique [0002] Elevator is a kind of vertical elevator powered by electric motor, equipped with box-shaped gondola, which is used for multi-storey buildings to take people or carry goods. There is also a step type, and the tread plate is installed on the crawler belt to run continuously, commonly known as an escalator or a moving walk. Fixed lifting equipment serving specified floors. For the sake of safety, regular maintenance is usually required, and safety protection devices need to be installed during maintenance to protect the safety of maintenance personnel. [0003] But existing technology has following deficiency: [0004] 1. Traditional safety protection devices have poor protection effect and are prone to safety accidents; [0005] 2. When the traditional sa...
