Description

Technical Field

[0001] The utility model relates to the technical field of freight elevators, in particular to a gap detection device for freight elevator monitoring. Background Art

[0002] Freight elevator is a kind of vertical lift powered by electric motor, equipped with box-shaped pod, used for multi-storey buildings to carry people or goods. Freight elevator is a large-scale electromechanical equipment with high degree of automation. Freight elevator has been widely used in factories, warehouses, shopping malls, hotels, airports, stations. Freight elevator needs to be inspected and maintained regularly. The detection of gaps in freight elevator is a very important part of daily maintenance of freight elevator. The size of the gap directly affects the safety performance of freight elevator operation.

[0003] The gap detection device used for freight elevators in the prior art is not easy to adjust, so when the detection device is needed to detect the gap of the freight elevator, the detection effect is not good. When the detection device is used to detect the gap of the freight elevator, it is not effective for people to perform depth detection of the gap of the freight elevator, thereby reducing the accuracy of the detection device. For this reason, we propose a gap detection device for freight elevator monitoring. Utility Model Content
