Problems solved by technology

It provides a motor grader electric control method to solve the technical problems of inconvenient installation, low transmission efficiency, low service life, high operating noise and low reliability caused by the existing loader drive system
The disadvantage of this solution is that there is an error between the motor drive and the arm reaching the exact position, and it is impossible to accurately judge whether the arm or the dump is in place

Embodiment 1

[0031] like figure 1 As shown, a dual-motor control system for an electric loader includes a controller 40 in addition to a pilot handle 10, a boom mechanism 20, and a bucket mechanism 30. The controller 40 is connected to the pilot handle 10 to receive information from the pilot handle. 10 movement commands, such as lifting, lowering, bucket lifting, bucket unloading, etc.

[0032] The controller 40 is also connected with two motors, and the two motors are respectively connected with a mechanical transmission mechanism to drive the boom mechanism 20 and the dump mechanism 30 to move. Specifically in this embodiment, the controller 40 is connected to the boom motor 21, the boom motor 21 is connected to the mechanical transmission mechanism I22, and the mechanical transmission mechanism I22 is connected to the boom mechanism 20, so as to drive the mechanical transmission mechanism through the motor and then drive the boom mechanism 20. Compared with the traditional hydraulic t...

Embodiment 2

[0039] A dual-motor control method for an electric loader, using the above system, and including:

[0040] Receive movement instructions from the pilot handle 10, such as movement instructions such as lifting, lowering, lifting buckets, and unloading buckets.

[0041] Control the operation of the corresponding motor according to the movement command, that is, control the operation of the boom motor 21 or the bucket motor 31 .

[0042] The position signals of the two position sensors in the corresponding position sensor group are collected in real time. For example, when the boom motor 21 is started, the position signals of the position sensor I51 and the position sensor II52 are collected in real time, so as to judge according to the position signal difference of the position sensors in the corresponding group Whether the electric loader is running normally, if the difference is not greater than 0.2V, the electric loader is running normally, otherwise the electric loader is no...

Abstract

The invention discloses an electric loader dual-motor control system and method and belongs to the technical field of electric loader control. The system comprises a pilot handle, a big arm mechanism and a tipping bucket mechanism, and further comprises a controller, wherein the controller is connected with the pilot handle, the controller is further connected with two motors and two position sensor sets; the two motors are connected with transmission mechanisms respectively to drive the big arm mechanism and the tipping bucket mechanism to move; each position sensor set comprises two position sensors; and one position sensor set is used for respectively detecting the moving position of the big arm mechanism and the moving position of the transmission mechanism corresponding to the big arm mechanism, and the other position sensor set is used for detecting the moving position of the tipping bucket mechanism and the moving position of the transmission mechanism corresponding to the tipping bucket mechanism. The motors are used for pushing the mechanical transmission mechanisms, so that compared with hydraulic transmission, the efficiency is improved, and the response speed is increased, whether the large arm or the tipping bucket is in place or not is accurately judged, errors are avoided, and the operation accuracy and safety of the electric loader are improved.

Description

technical field [0001] The invention relates to the technical field of electric loader control, in particular to a dual-motor control system and method for an electric loader. Background technique [0002] A traditional loader consists of a pilot handle, a hydraulic control valve body, an oil pump motor, a lifting arm mechanism, and various oil pipes. The pilot handle control controls the small oil circuit to control the large oil circuit of the valve body, and generates huge pressure to complete various mechanical linkage mechanisms, such as lifting, lowering, unloading bucket, lifting bucket, etc., but there is a conversion of hydraulic pressure during the conversion process. The efficiency is low, and the sensitivity of lifting cannot reach the real-time effect. [0003] Corresponding improvements have been made in response to the above problems. For example, the Chinese patent application with the publication date of 2012-07-11 and the publication number CN102561429A di...
