Technical Field

[0001] The utility model relates to the technical field of elevator detection equipment, in particular to a stability detection device for elevator operation. Background Art

[0002] An elevator is a permanent transportation device that serves several specific floors in a building. Its car runs on at least two rows of rigid tracks that are perpendicular to the horizontal plane or have an inclination angle of less than 15° to the plumb line. There are also stepped types, with treads mounted on tracks and running continuously, commonly known as escalators or moving walkways, which are fixed lifting equipment that serve specified floors.

[0003] The prior art has the following deficiencies; in the prior art, the publication number CN215160053U states, "A stability detection device for elevator trial operation" comprises a base plate, a plurality of corresponding support leg assemblies are installed on the side of the base plate, a first plug-in tube is fixedly provided on the upper surface of the base plate, a plug-in rod is inserted and fixed in the first plug-in tube, an iron disc is fixed on the top of the plug-in rod, a transparent cylinder is placed on the iron disc, a magnetic attraction is fixed on the top of the transparent cylinder, a barrel cover is threadedly installed on the top of the transparent cylinder, liquid is contained in the transparent cylinder, a hollow floating plate is provided above the liquid, a plurality of guide rods arranged parallel to the transparent cylinder are fixedly installed on the hollow floating plate, the top ends of the guide rods all extend upward until they pass through the barrel cover, a top plate is fixedly installed between the top ends of the guide rods, a second plug-in tube is fixedly installed on the top plate, a marker pen is inserted in the second plug-in tube, a writing board corresponding to the marker pen is provided on one side, a vertical rod is fixedly installed on the bottom end of the writing board, and the vertical rod is fixedly connected to the iron disc."

[0004] When in use, the above-mentioned device observes the horizontal surface of the liquid in the transparent cylinder to determine whether the elevator is tilted. During the operation of the elevator, the length of the line drawn on the writing board with a marker is used to intuitively reflect the smoothness of the elevator operation. The structure is simple and the cost is low. However, during the inspection, the smoothness of the elevator can only be detected by observing the changes in the lines on the writing board with the naked eye. The tilt angle of the elevator during operation cannot be detected, and the accuracy is low. Utility Model Content

The writing end of the writing pen 602 is in contact with the writing paper 701. When the elevator shakes during operation, the bottom of the swing arm 601 will swing with the shaking of the elevator, and drive the writing pen 602 to swing around the support rod 502, draw lines on the writing paper 701, and observe in conjunction with the angle line 702, so that the specific tilt angle can be obtained.
