Problems solved by technology

During the milling operation, if the transmission belt slips, it will reduce the transmission efficiency of the milling drum and affect the working efficiency of the milling machine. If it is not handled in time, it will even cause damage to the transmission belt and cause the milling machine to stop.
Existing milling machines can only determine the state of the transmission belt when the milling drum is out of operation. There is a lag, and the milling machine must be shut down for maintenance, which affects construction efficiency and progress.

Embodiment 1

[0061] In this embodiment, a milling machine transmission detection system 1 is provided, which is used in the milling machine 2 to detect whether the transmission belt 243 of the milling machine 2 is in a slipping state. like figure 1 and figure 2 As shown, the milling machine transmission detection system 1 includes a first detector 11 , a second detector 12 and a controller 13 .

[0062]The first detector 11 serves to detect the rotational speed of the milling drum 23 . Wherein, the first detector 11 may be a rotational speed sensor or other equipment capable of detecting the rotational speed of the milling drum 23 , specifically, it may be provided at the pulley or the reducer of the milling machine 2 so as to detect the rotational speed of the milling drum 23 . The second detector 12 is used to detect the load state of the milling drum 23 , that is, to detect whether the milling drum 23 is loaded or unloaded, so as to determine whether the milling drum 23 is performing...

[0067] like image 3 and Figure 4 As shown, the milling machine transmission detection system 1 also includes a third detector 14 . The third detector 14 is arranged on the tensioning oil cylinder 25 of the milling machine 2, and is used for detecting whether the piston of the tensioning oil cylinder 25 is in the working position. Specifically, the third detector 14 can detect the piston position of the tensioning oil cylinder 25, and can also detect the oil pressure of the tensioning oil cylinder 25, and determine whether the piston is in the working position through the oil pressure of the piston at different positions. Simultaneously detect the piston position and oil pressure, so as to use the two parameters of the piston position and oil pressure to determine whether the piston is in the working position. The third detect...

Abstract

The invention provides a milling transmission detection system, a milling machine and a milling machine transmission detection method. Wherein, the milling transmission detection system includes: a first detector, used to detect the rotating speed of the milling drum; a second detector, used to detect the load state of the milling drum; a controller, connected with the first detector and the second detector The controller and the engine of the milling machine are electrically connected, and the controller determines whether the transmission belt of the milling machine is in a slipping state according to the transmission ratio of the milling drum when it is no-load and the transmission ratio when it is loaded. The technical scheme of the present invention can detect whether the transmission belt is slipping during the construction process of the milling machine, so that the operator can handle and maintain the slipping transmission belt in time, so as to prevent the loss from expanding and affect the milling operation, which is beneficial to improve Milling machine reliability and construction efficiency. In addition, the transmission detection system of the milling machine is simple, easy to assemble, and has strong versatility.

Description

technical field [0001] The present application relates to the technical field of milling machine transmission detection, in particular, to a milling machine transmission detection system, a milling machine and a milling machine transmission detection method. Background technique [0002] At present, the milling drum of the milling machine is mostly driven by a pulley mechanism to drive the rotation of the milling drum to realize the milling operation. During the milling operation, if the transmission belt slips, it will reduce the transmission efficiency of the milling drum and affect the working efficiency of the milling machine. If it is not handled in time, it will even cause damage to the transmission belt and cause the milling machine to malfunction and stop. Existing milling machines can only determine the state of the transmission belt when the milling drum is out of operation, and there is a hysteresis, and the milling machine must be shut down for maintenance, which...
