Abstract
A loading safety braking device of an electric wheel mining dump vehicle is characterized in that two signal output ends of a ganged switch are in electric connection with an on-off input end of a controller, the control is special for the electric wheel mining dump vehicle, the on-off input end of the controller is simultaneously in electric connection with one ends of two identical electromagnetic valves and the negative electrode of a fly-wheel diode, and the other ends of the two electromagnetic valves are simultaneously in electric connection of the positive electrode of the fly-wheel diode and are connected to the ground at the same time. The loading safety braking device of the electric wheel mining dump vehicle has the function of achieving loading braking, and has the advantage of being good, safe and reliable in braking effect.
Description
Technical field
The utility model relates to mining dump truck with electric wheels, is specifically related to mining dump truck with electric wheels loading safety brake equipment, belongs to the mining dump truck with electric wheels technical field.
Background technology
mining dump truck with electric wheels is the main tool of nation, the working environment of mining dump truck with electric wheels is generally: the time of lade is generally shorter, but larger from impulsive force to mining dump truck with electric wheels of goods during lade, so, in the course of the work, navigating mate does not generally need engine off, and the pedal brake system that arranges by mining dump truck with electric wheels self simultaneously brakes, to prevent that impulsive force that Container Loading is from causing the displacement of mining dump truck with electric wheels, and other safety misadventure that causes thus, obviously, long period is carried out pedal brake, easily cause the fatigue of navigating mate, the impact of human element in addition, easily cause braking unreliable, thereby and cause corresponding safety misadventure.although also have in the prior art for the existing defects of mining dump truck with electric wheels and do corresponding improvement, for example: China Patent No. 201120172879.X patent name is " the loading brake system device of mining dump truck with electric wheels ", this patented technology is by arranging a cover by switch, controller, and electromagnetic valve, the independent operatorless device that flywheel diode forms, solve the existing defective of pedal brake, but, to be in coal dust more due to switch and electromagnetic valve, impact under larger harsh environment and work, easily damage and work unreliable, in case above-mentioned situation occurs, inevitably can cause corresponding safety misadventure.
Summary of the invention
The purpose of this utility model is: for the existing defects of brake equipment of existing mining dump truck with electric wheels, the utility model provides a kind of novel mining dump truck with electric wheels loading safety brake equipment, overcomes existing defects in prior art.
the technical scheme that the above-mentioned purpose that realizes the utility model adopts is: described mining dump truck with electric wheels loading safety brake equipment, it comprises: coupled twin switch, controller, electromagnetic valve, flywheel diode, it is characterized in that: two signal output parts of coupled twin switch and the switching value input end of controller electrically connect, described controller is mining dump truck with electric wheels self nonshared control unit, described coupled twin switch is arranged on the gauge panel position of operator's compartment front end, the switching value mouth of controller connects with an end of two same solenoid and the negative electricity of flywheel diode simultaneously, an other end while of two electromagnetic valves electrically connects and while ground connection with the positive pole of flywheel diode.
principle of work of the present utility model is: on the instrument carrier panel of the front end of operator's compartment or near the coupled twin switch of described setting, when vehicle stops lade, press the button of coupled twin switch, two coupled twin switches with identical function are worked simultaneously, the switching value signal that loads braking enters in controller, switching value electric signal of controller output is given two identical electromagnetic valves simultaneously, and the brake activation valve group of control hydraulic efficiency pressure system, from but vehicle enters braking mode, due to two switch and electromagnetic valves with identical function being set simultaneously, when any one element work mal wherein, other element still can be realized normal work, according to principle of probability, two simultaneous possibilities of event are less, in the utility model, two identical events are exactly two switches and out-of-run event of electromagnetic valve while.
Beneficial effect: can be found out by principle schematic of the present utility model and principle of work, the utility model not only has the function that realizes loading braking, simultaneously, have advantages of that braking effect is safe and reliable, thereby and avoid due to the unreliable defective that causes safety misadventure to occur of braking.
Description of drawings
Accompanying drawing 1 is principle schematic of the present utility model;
Shown in figure: 1, coupled twin switch; 2, controller; 3, electromagnetic valve; 4, flywheel diode.
