Abstract

The invention relates to an automobile safety alarming device, in particular to a highway vehicle-mounted alarming machine frame. The highway vehicle-mounted alarming machine frame comprises a base frame fixed to the top of a vehicle, wherein first driving mechanisms are hinged at one ends of the front end or the rear end of the base frame, the first driving mechanisms are connected to sliding module sets along a horizontal shaft and drives the sliding module sets to move, connecting rods are hinged between the sliding module sets and rotary racks, installation racks are arranged on the rotaryrack in a telescopic mode, second driving mechanisms driving the installation racks to stretch and contract are connected on the installation racks, and an alarming device is fixed to the top ends ofthe installation racks. According to the highway vehicle-mounted alarming machine frame, overturning, lifting and lowering of the alarming device are achieved, when alarming is not needed, the wholealarming frame is in a horizontal state, and normal running of an automobile is not influenced; and when alarming is not needed, the alarming device faces downwards, influence of wind and sun is avoided, and the service life is long.

Description

technical field [0001] The invention relates to an automobile safety warning device, in particular to a vehicle-mounted warning frame for expressways. Background technique [0002] The environment of expressway maintenance is dangerous. In order to ensure construction safety, warning frames are indispensable. The existing warning frame has a large volume and has high requirements on the vehicle on which the warning frame is installed, and is usually installed on a pickup truck with a vehicle body. This project designs a liftable folding warning frame, which is small in size and can be installed on the roof of ordinary vehicles. [0003] status quo: [0004] Road construction on expressways is very dangerous. If safety warnings and guidance signs or equipment are not installed, safety accidents are likely to occur. Most of the existing warning and guidance equipment are installed on towed or hand-push vehicles. On the rack, due to the need for manual operation, this rack h...
