Road transition automatic lifting device for governing bump at bridgehead

Abstract

The invention discloses a road transition automatic lifting device for governing bump at a bridgehead. The device comprises a transition road plate, a control panel, a hydraulic machine, a cylindricalcontactor, a safety alarm lamp and an electromagnetic relay, when sedimentation occurs, the transition road plate is subjected to compressive force and transmits information to the control panel fixed below, meanwhile, the hydraulic machine is started to push the cylindrical contactor to make contact with the control panel and support the transition road plate, the hydraulic machine keeps the original height, the transition road section of the whole road surface and the bridge surface becomes smooth, and the electromagnetic relay is installed in the automatic lifting device and used for controlling signals sent by the safety alarm lamp. The height of the transition road plate is automatically adjusted mainly through the automatic lifting device, the roadbed and the bridgehead are effectively connected in sequence, the problem of bridgehead bumping is effectively solved, and the link of later manual maintenance is reduced.

Description

technical field [0001] The invention relates to the technical field of vehicle jumping at the bridge head, in particular to an automatic lifting device for road transition to control the vehicle jumping at the bridge head. Background technique [0002] Nowadays, the proportion of roads and bridges in the road is increasing, and the disease of vehicle jumping at the bridge head is very common, and it is also an important hidden danger in driving safety. The vehicle jumping at the bridge head directly affects the safety and comfort of driving, resulting in a great safety hazard , for vehicles transporting important items, there is also the possibility of damage to the items. Therefore, the phenomenon of vehicle jumping at the bridge head must be paid attention to, and comprehensive analysis is made to propose effective and reasonable prevention and maintenance measures. The methods of jumping off the vehicle mainly include setting bridge head slabs, geogrids and laying asphalt...

Problems solved by technology

[0002] Nowadays, the proportion of roads and bridges in the highway is increasing, and the disease of vehicle jumping at the bridge head is very common, and it is also an important hidden danger in driving safety. The vehicle jumping at the bridge head directly affects the safety and comfort of driving, resulting in a great safety hazard , for vehicles transporting important items, there is also the possibility of damage to the items. Therefore, the phenomenon of vehicle jumping at the bridge head must be paid attention to, and comprehensive analysis is made to propose effective and reasonable prevention and maintenance measures. The methods of jumping vehicles are currently mainly including setting up the bridge head, geogrid and laying asphalt, etc., which have achieved certain effects, but the effect is not very obvious.
