An automatic lifting device for road transition to control bridge head jumping

Abstract

The invention discloses a road transition automatic lifting device for controlling vehicle jumping at the bridge head, which comprises: a transition road board, a control panel, a hydraulic press, a cylindrical contactor, a safety alarm lamp, and an electromagnetic relay. Compressive force, transmit information to the control panel fixed below, at the same time start the hydraulic machine to push the cylindrical contactor to contact the control panel, and support the transition road plate, while the hydraulic machine maintains the original height, so that the entire road surface and bridge The transition road section on the surface becomes smooth, and the electromagnetic relay is installed inside the automatic lifting device to control the signal sent by the safety alarm light. The present invention mainly automatically adjusts the height of the transition road board by using the automatic lifting device, effectively Connecting the subgrade to the bridge head effectively solves the problem of car jumping at the bridge head and reduces the manual maintenance in the later stage.

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...

[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.
