Wheel type cold milling machine pre-delivery detection device

Abstract

The invention discloses a wheel type cold milling machine pre-delivery detection device, comprising a running system dynamometer and a milling drum dynamometer; the running system dynamometer comprises a rack, a torque and seed sensor, a magnetic powder brake, a first roller, a second roller, a third roller and a fourth roller, wherein one end of a second central shaft on the second roller is connected with one end of a fourth central shaft on the fourth roller, one end of a first central shaft on the first roller is connected with one end of a third central shaft on the third roller, the other end of the third central shaft is connected with one end of a rotation shaft of the torque and speed sensor, and the other end of the rotation shaft of the torque and speed sensor is connected with an output shaft of the magnetic powder brake; the milling drum dynamometer comprises an electric eddy current dynamometer and a connection disc, wherein one end of the connection disc is connected with a rotation shaft of the electric eddy current dynamometer while the other end of the connection disc is connected with a rotation shaft of a milling drum. The detection device can rapidly obtain the speed parameter and torque parameter of the running system and the rotation speed and torque parameter of the milling drum, and can be applied to performing pre-delivery detection to the wheel type cold milling machine.

Description

technical field [0001] The invention belongs to the technical field of detection of wheel-type cold milling planers, and in particular relates to a delivery detection device for wheel-type cold milling planers. Background technique [0002] In recent years, my country's highway traffic industry has developed vigorously, and highway construction has made great progress. Graded highways will enter a new period where construction is the main focus, and gradually shift to construction and maintenance, and then transition to a new era where maintenance is the main focus. At the same time, there are many road quality problems, coupled with overloading and a sharp increase in traffic volume, road maintenance and regeneration tasks will increase year by year. As the main model of asphalt pavement maintenance, the cold milling machine, the performance of the whole machine, especially the operating performance, has become the core content of the manufacturing process and factory inspe...

AI Technical Summary

Problems solved by technology

However, the working conditions of the road surface cold milling machine are complicated, and there are many types of asphalt pavement materials. Especially in recent years, a large number of modification technologies have been adopted, and the strength of the asphalt pavement has been greatly improved, which makes the cutter on the milling drum bear more during the milling process. Large load impact, and this cyclic load fluctuates periodically from zero to maximum, especially when milling with large width and depth

Severe slippage and insufficient milling power often occur during the working process of the wheel milling machine, which leads to a decrease in the quality and efficiency of the work. Often only the working parameters can be changed, which will inevitably affect the reasonable matching between the parameters, resulting in increased tool wear and machine Increased maintenance costs and frequent breakdowns

Due to the particularity of the structure of the milling machine, there is no special factory inspection device, so that the parameters matching and manufacturing assembly related problems of the milling machine cannot be found and dealt with in time during the parameter design and manufacturing process
