Description

Technical Field

[0001] The utility model relates to a device for quickly measuring the engagement depth of a sliding block of an elevator floor door, and belongs to the technical field of elevator inspection and testing equipment. Background Art

[0002] During regular elevator inspections, the main problems with landing door guide shoes include missing guide shoes, missing sliders, missing metal connector nuts, improperly installed guide shoes, and severely worn sliders. If the slider engagement depth is shallow, the contact surface between the guide shoe and the chute is small, significantly reducing the door's holding force and impact resistance. Therefore, measuring the engagement depth of elevator landing door sliders is a key aspect of elevator inspections. Existing techniques require measuring the engagement depth of the slider and its chute, then measuring the gap between the slider bottom and the chute bottom, and then subtracting the gap between the slider bottom and the chute bottom from the chute depth. This method is very inconvenient.

[0003] In order to conveniently measure the engagement depth of elevator floor door sliders, a Chinese invention patent application with application publication number CN115655070A discloses an elevator floor door slider engagement depth measuring ruler, which includes a main body for being horizontally arranged in the floor door sill slide groove, a wedge-shaped measuring slider and a wedge-shaped measuring slider are arranged parallel to each other in the main body, the wedge-shaped measuring slider and the wedge-shaped measuring slider are fixedly connected by a connecting piece, a ruler frame is vertically arranged above the wedge-shaped measuring slider on the main body, a vernier ruler with a liftable scale is provided in the ruler frame, one end of the vernier ruler passes through the main body and contacts the upper surface of the wedge-shaped measuring slider, and the contour figures formed by the wedge-shaped measuring slider and the wedge-shaped measuring slider on the longitudinal section are congruent. This type of elevator floor door slider engagement depth measuring ruler has a complex structure and is not suitable for on-site measurement. If the on-site slider is installed to the side, the measuring instrument is not easy to place.

[0004] To simplify the structure, a Chinese invention patent application, publication number CN114291708A, discloses a device for detecting the engagement depth of the lower guide and retaining device of an elevator landing door. The device comprises a detection body having a connecting abutment portion and a measuring portion. When the detection body is inserted into the sill groove, the abutment portion can abut the lower bottom surface of the slider of the guide and retaining device. The measuring portion has a scale marking area for the user to read the vertical distance from the lower bottom surface of the slider to the upper surface of the sill groove. When in use, the abutment portion of this detection device is in surface contact with the bottom surface of the slider. Ideally, when measuring on-site, the bottom of the slider is flat. However, if the bottom of the slider is partially worn or missing, the measurement will be inaccurate. The detection device disclosed in the aforementioned patent needs to be lifted upward during measurement to allow the abutment portion to fit the slider, making measurement more inconvenient.
