Description

Technical Field

[0001] The present application relates to the technical field of municipal engineering, and in particular to a height limiting device. Background Art

[0002] On municipal engineering roads, in order to reduce the occurrence of traffic accidents and protect road safety, it is necessary to set up height limit devices. Existing road height limit devices generally only include fixed height limit frames, which are composed of two columns and a beam. Both the columns and the beam are steel structures. This type of road height limit device forcibly limits the height of passing vehicles through the beam, and informs the driver of the height limit by affixing a sign on the beam or column.

[0003] A Chinese patent with patent number CN219653599U discloses a height limiting device for municipal engineering. The top end of the screw is connected and fixed to the output shaft of a servo motor arranged at the top end of a movable slot through a coupling. The height limiting rod can be driven to rise through a lifting mechanism, so as to allow vehicles to pass through in some special circumstances.

[0004] During use, the above-mentioned device drives the screw rod to be raised and lowered by a servo motor. However, when installing the device on roads of varying widths, the use of the device is limited, making it inconvenient to use on wider or narrower roads. Utility Model Content
