Embodiment

[0025] This embodiment provides a vehicle control system for metallurgy-specific crawler loaders, such as figure 1 As shown, the system includes hydraulic transmission and control system and electrical control system.

[0026] The hydraulic transmission and control system includes a hydraulic closed travel drive system and a load sensitive variable open working hydraulic system, such as figure 2 shown.

[0027] 【Hydraulic closed travel drive system】

[0028]After the mechanical energy (torque and speed) output by the engine passes through the transfer case, a part of the mechanical energy is converted into hydraulic energy (flow and pressure) through the proportional variable pump, and the hydraulic energy is transmitted to the hydraulic motor through the pipeline, and the hydraulic motor converts the hydraulic energy into mechanical energy (torque and rotational speed), the mechanical energy acts on the drive sprocket of the final drive, thereby driving the track to rotate...

Abstract

The invention discloses an entire-vehicle control system for a special metallurgical crawler loader and a control method thereof. The system comprises a hydraulic transmission and control system and an electric appliance control system, wherein the hydraulic transmission and control system comprises a closed traveling hydraulic drive system and an open load sensitive variable working hydraulic system; an engine is connected with a transfer case; a proportional variable pump is arranged at a power take off (PTO) opening of the transfer case, and is connected with a hydraulic motor which is connected with a final transmission drive chain wheel; an open load sensitive variable pump is arranged at the PTO opening of the transfer case, and is connected with a proportional multiway valve; a movable arm oil cylinder and a shovel loader oil cylinder are connected with the proportional multiway valve respectively; and the electric appliance control system comprises an engine controller and an intelligent terminal display which are connected with a programmable logic controller (PLC) by a controller area network (CAN) bus respectively. The entire-vehicle control system and the control method thereof can greatly optimize power matching between the engine and a power train, greatly improve the working efficiency and are safe and reliable.

Description

technical field [0001] The invention belongs to the technical field of electric appliance control, and relates to a complete vehicle control system and a control method of a metallurgical crawler loader. Background technique [0002] In iron and steel plants, due to the harsh working environment, high temperature, high dust, and high work intensity in steelmaking production, furnace bottom slag cleaning operations in domestic iron and steel plants all use the ZY-65 crawler type produced by Huanghe Engineering Machinery Factory. Loader to complete. The ZY-65 crawler loader adopts hydraulic driving and mechanical linkage operating device, and the driver must drive the vehicle into the dangerous area of ​​the furnace bottom for operation; it has caused a huge safety hazard to the driver's personal safety. Crawler loaders are mainly used for shoveling and loading work in steel mills, mines, etc., which need to meet the requirements of high operating power, short working cycle t...
