A mechanical floor display device applied to elevator machine room

Abstract

The invention relates to a mechanical floor display device applied to an elevator machine room. The mechanical floor display device applied to the elevator machine room is characterized by comprisinga rope wheel, the rope wheel is connected with a steel wire rope of a traction machine, the rope wheel is driven to rotate through the steel wire rope, a gear set used for decelerating is arranged onthe rope wheel, an output shaft is arranged at the output end of the gear set, an adjusting shaft is connected to the output shaft, the adjusting shaft and the output shaft are arranged in a perpendicular mode and transmitted through a pair of friction wheels perpendicular to each other, an adjusting gear is fixed on the adjusting shaft, the adjusting gear is connected with a sliding gear in a meshed mode, a transmission shaft is fixedly arranged on the sliding gear in a penetrating mode, and a floor display device body is connected to the transmission shaft. According to the mechanical floordisplay device applied to the elevator machine room, the gear transmission principle and the spiral transmission principle are used, a digital wheel on the device can be driven to rotate to display the number of the corresponding floor when an elevator runs, by means of the device, a worker can intuitively determine the current floor position, and then the valuable time for rescuing the trapped personnel and debugging the elevator is saved.

Description

technical field [0001] The invention belongs to the field of elevators, in particular to a mechanical floor display device applied to an elevator machine room. Background technique [0002] At present, with the increase in the number of elevators, the number of maintenance elevators and solving the problem of trapped people in elevators has also increased simultaneously. However, the elevator floor display in the machine room still uses the traditional method of painting on the wire rope to display binary. [0003] In the emergency situation when the elevator is trapped, the staff need to observe the binary number on the wire rope first, and then calculate the position of the floor according to the binary number. This traditional method is difficult to judge the accurate floor due to human reasons, which leads to delays in rescue time, which leads to The most serious thing is not only the contradiction between passengers and rescuers, but even life-threatening in dangerous s...

[0003] In the emergency situation when the elevator is trapped, the staff need to observe the binary number on the wire rope first, and then calculate the position of the floor according to the binary number. This traditional method is difficult to judge the accurate floor due to human reasons, which leads to delays in rescue time, which leads to It is not only the conflict between passengers and rescuers, but even life-threatening in dangerous situations.
