Elevator over-speed governor checking device capable of remotely monitoring and monitoring and checking method thereof

Abstract

The invention provides an elevator over-speed governor checking device capable of remotely monitoring. The checking device comprises a driving speed adjusting module, a first action detecting module, a second action detecting module, a data remote sending module, a data remote receiving module, a data processing module, a first speed detecting module, a second speed detecting module and a displaying module, wherein the second speed detecting module is used for being compared with the first speed detecting module to remotely monitor the state of maintenance unit personnel over detecting of an elevator over-speed governor. According to the checking device, checking parameters of the over-speed governor can be remotely obtained, and through the checking parameters, the state of the maintenance unit personnel can be remotely monitored to detect the elevator over-speed governor so as to ensure that the maintenance unit personnel complete checking for the elevator over-speed governor on a site. The invention further provides a monitoring and checking method of the checking device, the method can reduce the time consumed by the institution personnel of the both sides in the checking process to improve the working efficiency of the personnel of the both sides and can meet the national checking requirements, so that the accuracy of qualified checking data of the elevator over-speed governor is ensured.

Description

technical field [0001] The invention relates to the technical field of elevator detection, and more specifically, to a remote-monitorable elevator overspeed governor verification device and a monitoring and verification method thereof. Background technique [0002] As an important part of modern infrastructure supporting projects, elevators are closely related to national economic construction, especially the development of real estate and the improvement of people's quality of life. Elevator speed limiter-safety gear linkage system is the most critical protection when the elevator stalls. Among them, the speed limiter is the safety component of the elevator. Its function is to monitor and control the speed of the car at any time and to issue protection instructions when the elevator is overspeed. . Therefore, whether the speed limiter can give correct protection instructions when an accident occurs is directly related to the safety of people's lives and property. The spee...

Problems solved by technology

[0006] The inspection requirements after the revision put more emphasis on the inspection of the inspection items of the speed limiter, and paid more attention to the process quality of the inspection of the speed limiter, and strengthened the supervision of the inspection quality. At the same time, it was more clear and reduced the implementation of inspection The main body increases the on-site observation and confirmation, which will greatly affect the work efficiency of both the calibration and inspection agencies, and poses new challenges to the workload of the maintenance unit and the inspection time of the inspection agency

[0007] With the development of elevators, the number of elevators is increasing rapidly, and the speed limiter is one of the necessary safety components for each traction elevator (the current mainstream type). the amount is huge

Secondly, the speed limiter forms one of the important safety protection systems of the elevator through the steel wire rope, the tensioner and the safety gear. When checking, the elevator must be stopped first, and tools are used to separate the speed limiter from the steel wire rope. Many, the verification time is longer

Finally, the installation position of the elevator speed limiter is different. Generally, the traction elevator is installed on the machine room. For machine room-less elevators, the speed limiter is installed in the elevator shaft and pit. Due to the different installation positions, the difficulty of on-site calibration is difficult to estimate , the time required for calibration is quite different

Therefore, according to the inspection method of the revised inspection regulations, the maintenance unit and the inspection personnel confirmed on site must be on site at the same time, and neither party can perform other regular inspection and test work during the whole process. Therefore, this work requires a lot of manpower and time, it poses a very big challenge to the human resources of maintenance units and inspection agencies
