A wheel-type cold milling machine factory inspection device

Abstract

The invention discloses a factory inspection device for a wheeled cold milling planer, which includes a walking system dynamometer and a milling drum dynamometer, and the walking system dynamometer includes a frame, a torque speed sensor, a magnetic powder brake and a first roller , the second drum, the third drum and the fourth drum, one end of the second central shaft on the second drum is connected to one end of the fourth central shaft on the fourth drum, and one end of the first central shaft on the first drum is connected to the third drum. One end of the third central shaft is connected, the other end of the third central shaft is connected to one end of the rotating shaft of the torque speed sensor, and the other end of the rotating shaft of the torque speed sensor is connected to the output shaft of the magnetic powder brake; the milling drum dynamometer includes an eddy current dynamometer One end of the connecting plate is connected with the rotating shaft of the eddy current dynamometer, and the other end of the connecting plate is connected with the rotating shaft of the milling drum. The detection device can quickly obtain the speed parameters and torque parameters of the traveling system, the milling drum speed and torque parameters, and carry out the factory inspection of the wheel 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
