Material-paving track tracker

Abstract

The invention relates to a material-paving track tracker, which is used for tracking and adjusting the paving track during paving materials. The material-paving track tracker comprises a sensor and a controller, wherein the sensor part comprises a terminal and a laser sensor which can distinguish great color difference; and the controller part comprises a CPU, a power-switching circuit, an optically coupling isolating circuit, a filter circuit, a relay driving circuit, a relay output circuit and a transducer. The material-paving track tracker is characterized in that: the material-paving track tracker can automatically track according to the track of the paved materials and automatically adjust the deflection caused by paving; the optically coupling isolating circuit and the filter circuit can effectively reduce the shaking frequency of a construction vehicle in the process of paving a water-proof material; and the adjustable speed of the steering system of the construction vehicle can be adjusted by the transducer.

Description

technical field [0001] A material laying trajectory tracker is based on the optical principle, collects the optical characteristic information of the laying material trace, transmits the signal to the CPU, and outputs the output to change the steering of the three-phase motor to automatically adjust the steering system, so that the laying equipment automatically moves along the trace. This system can be installed on construction machinery running at low speed (3-5m / min) to realize automatic tracking of the laying track of paving materials. This system is suitable for material laying trajectory tracking in two situations 1, materials with continuous or intermittent artificial marking 2, and situations where the color depth of the material and the laying environment have a large contrast. Background technique [0002] The track tracker is rarely used in domestic material laying, especially in the application of road and bridge waterproof material laying in my country. Its char...

Problems solved by technology

[0003] As far as the laying of road and bridge waterproof materials is concerned, the current domestic road and bridge waterproof materials are still mainly laid manually. Although there are also some hot-melt construction vehicles for road and bridge waterproof materials independently developed by our country, they are not very satisfactory. There are the following disadvantages: 1. The laying speed is slow, the work efficiency is low, the laying effect is average, and the energy consumption is relatively high

2. Low degree of automation

The construction process not only wastes manpower, but also adds many unsafe factors to the construction work.
