Abstract

The invention discloses a lifting control structure and a mining dump truck, and belongs to the field of machine manufacturing. The lifting control structure comprises an input unit, a calculation and logical judgment unit, an output unit and an execution unit which are connected in order, wherein the input unit comprises a plurality of button switches, the calculation and logical judgment unit comprises a controller 1, the output unit comprises a plurality of proportional solenoid valves, and the execution unit comprises a lifting cylinder 2; and the plurality of the button switches comprise a lifting switch 3 and a lowering switch 4, and the plurality of the proportional solenoid valves comprise a lifting proportional valve 5 and a lowering proportional valve 6 which are respectively connected with the lifting switch 3 and the lowering switch 4 through the controller 1. The lifting control structure is characterized in that the button switches with simple structure and low cost are used for replacing operating handles and are combined with the proportional solenoid valves to control the action of the lifting cylinder, so that the intelligence is improved and the cost can be effectively reduced.

Description

technical field

[0001] The invention belongs to the field of mechanical equipment control, and relates to a lifting control, in particular to a lifting control structure and a mining dump truck. Background technique

[0002] One of the main functions of mining dump trucks is to transport materials (such as coal, soil, stones, etc.). With the continuous development of technology, more and more users are more concerned about its intelligence, cost, reliability and safety.

[0003] The traditional lifting control method of the existing mining dump truck is to use the expensive and complex operating handle as the control input device, and the controller controls the ordinary solenoid valve to realize the simple lifting, lowering, floating and maintaining functions; Or a limit switch will be added to indicate whether the carriage is raised or lowered in place. This control method is a full manual control method, which cannot effectively prevent or reduce the collision between th...
