Description

Technical Field

[0001] The present invention relates to the technical field of elevator detection, and in particular to an elevator bottom space measurement and video recording device. Background Art

[0002] The elevator is a device that runs along a rigid guide rail in a closed or semi-closed shaft. The shaft space below the ground of the elevator terminal station is the pit. According to the relevant requirements for the pit space in Article A1.2.2.12 of TSG T7001-2023 "Rules for Elevator Supervision Inspection and Periodic Inspection", the bottom space of the car when it is at the lowest position of the shaft should be measured during the elevator supervision inspection, including: there is a space of not less than 0.50m×0.60m×1.00m in the pit, the free vertical distance between the pit floor and the lowest part of the car is not less than 0.50m, and the free vertical distance between the highest fixed part in the pit and the lowest part of the car is not less than 0.30m. At the same time, Article A1.3 of TSG T7001-2023 "Rules for Elevator Supervision Inspection and Periodic Inspection" stipulates that the entire process of the pit buffer compression test needs to be recorded by audio and video during the elevator supervision inspection and periodic inspection.

[0003] At present, the bottom space is mainly measured by the indirect method, that is, the inspector enters the pit to measure the relevant data when the car is leveled at the lowest floor station, minus the distance the car moves from the leveling position to the buffer is fully compressed. This method requires multiple measurements and has large measurement errors. The buffer compression audio and video recording is carried out by the inspector entering the pit to record by hand or using a bracket to fix the audio and video equipment in the pit for recording. Since there are at least two buffers in the pit, the inspector needs to go in and out of the pit repeatedly, and it often takes a lot of time to install the camera and adjust the camera angle. In addition, the pit space of some elevators (such as elevators installed in old residential buildings) is small, and there are moving parts and electrical equipment in the pit. It is very dangerous for personnel to enter the pit to work. At the same time, once there is water in the pit, the work will be obstructed and cannot be carried out. Summary of the invention
