Description

Technical Field

[0001] The utility model belongs to the technical field of stereo garages, and in particular relates to a wire rope loosening and breaking detection device for stereo garages. Background Art

[0002] At present, in high-rise multi-story parking garages, most of the lifting systems use wire rope lifting. The loosening and breaking of wire ropes during use directly affects the safe operation of the multi-story parking garage. Existing means of detecting loose and broken wire ropes usually include photoelectric detection, mechanical detection, etc. However, photoelectric detection may lead to misjudgment due to sensitivity issues, and mechanical detection usually uses a heavy hammer or a pressure wheel to act directly on the wire rope. Since the tension of different parts of the wire rope is different, the pressure wheel cannot adjust its preset force, resulting in inaccurate detection and misjudgment, affecting the normal operation of the multi-story parking garage. Therefore, how to accurately detect and correctly judge looseness and breaking has always been the focus of attention and research of technical personnel in this field.

[0003] Therefore, in the field of stereo garage technology, there is still a need for research and improvement on the stereo garage wire rope loosening detection device, which is also a research hotspot and focus in the current stereo garage technology field, and is also the starting point for the completion of the present utility model. Utility Model Content

[0004] Therefore, the technical problem to be solved by the utility model is to provide a device for detecting the loosening and breaking of steel wire ropes in a stereo garage, so as to solve the technical problem of misjudgment caused by inaccurate detection of the loosening and breaking of steel wire ropes.

[0005] To solve the above technical problems, the technical solution of the utility model is: a wire rope loosening detection device for a three-dimensional parking garage, comprising a mounting seat, a swing arm is rotatably mounted on the mounting seat through a first hinge shaft, a second hinge shaft is fixedly mounted on the swing arm, the second hinge shaft passes through the swing arm, a pressure wheel is rotatably mounted on one end of the second hinge shaft, the pressure wheel is located on a side of the swing arm away from the mounting seat, a connecting rod is provided at the other end of the second hinge shaft, the axis of the connecting rod is perpendicular to the axis of the second hinge shaft, an elastic element is provided between the connecting rod and the mounting seat, a touch rod is installed on the swing arm at one side of the mounting seat, a travel switch is provided on the mounting seat, and the travel switch corresponds to the position of the touch rod.

[0006] As an improvement, the connecting rod has a threaded section, the threaded section of the connecting rod penetrates the second hinge shaft in a radial direction of the second hinge shaft, and locking nuts are provided on both sides of the connecting rod at the second hinge shaft.

[0007] As a further improvement, the elastic element is a tension spring, one end of which is fixed to the end of the connecting rod, and the other end of which is fixed to the mounting seat.

[0008] After adopting the above technical solution, the beneficial effects of the utility model are:

[0009] The utility model provides a three-dimensional garage wire rope loosening detection device, which changes the traditional structure of only detecting by pressure wheel gravity, uses a balanced wire rope tension elastic element to adapt to different wire rope tensions, and greatly improves the detection accuracy.

[0010] Since the length of the connecting rod can be adjusted by the locking nut, the elongation of the tension spring is changed, thereby changing the preload force of the tension spring, thereby satisfying the force balance of steel wire ropes with different tensions and expanding the application scope of the utility model.
