Roller temperature control system for bituminous-pavement thermal regeneration maintenance vehicle

Abstract

The invention discloses a roller temperature control system for a bituminous-pavement thermal regeneration maintenance vehicle. The system includes a roller and a man-machine interface. A plurality of temperature sensors are arranged at an opening of the roller. The temperature sensors are connected with input ports of a PLC controller. The man-machine interface is connected an input port of the PLC controller. An output port of the PLC controller is connected with a solenoid valve. An entrance of the solenoid valve is connected with a fuel-gas tank through a pipe. An exit of the solenoid valve is connected with a combustion chamber through a pipe. A heating plate is arranged at the upper side of the combustion chamber. The roller temperature control system for the bituminous-pavement thermal regeneration maintenance vehicle has the characteristics of being high in automation degree, capable of realizing procedural, intermittent and precise automatic control of heating and temperature measurement of mixed materials in the roller and the pavement, high in operation quality, stable in performance and long in service life.

Description

Technical field [0001] The invention belongs to the technical field of maintenance machinery, and relates to a temperature control system, in particular to a temperature control system for a roller of an asphalt road thermal regeneration maintenance vehicle. Background technique [0002] Small area diseases of asphalt concrete pavement (such as cracks, potholes, cracks, etc.) are the most common in the road maintenance process. The repair methods for these small area diseases mainly include cold repair and hot repair. The cold repair method is a traditional method. This method requires a lot of manpower and mechanical equipment, is time-consuming and expensive. In addition, a weak joint will be formed between the hot mixture and the surrounding cold material. The heavy load rolling, the weak joint between the old and the new will separate, forming a water seepage channel, and the water infiltrates and destroys the road base layer, reducing the service life of the road. The hot r...

AI Technical Summary

Problems solved by technology

[0003] The temperature of the material in the drum of the asphalt pavement thermal regeneration maintenance vehicle needs to be measured in time to keep the material in it at an appropriate temperature. This requires the installation of a suitable temperature control system on the asphalt pavement thermal regeneration maintenance vehicle. The existing temperature control The system has problems such as high cost and inaccurate measurement data
