Abstract
The utility model discloses a PLC control device for a gearbox adopting an electric control gear-shifting gearbox. The PLC control device comprises the electric control gear-shifting gearbox connected with a gear control solenoid valve group, and is characterized in that the gear control solenoid valve group is connected with a PLC through a program control module; each solenoid valve in the gear control solenoid valve group is controlled by the program control module to be switched on or off; the input terminal of the PLC is connected with a control button comprising a gear-increasing button '+', a neutral gear button '0' and a gear-reducing button '-'; and the control button is connected with a power supply V. The PLC control device has a simple structure; the direction and the gear of the gearbox can be controlled by three buttons integrated on a handle; and the PLC control device is convenient for operation and control and is safe and reliable.
Description
Technical field
The utility model relates to a kind of down-hole trackless mining vehicle, specifically a kind of gearbox PLC control gear.
Background technique
Gearbox is crucial parts in the down-hole trackless mining vehicles such as scraper, underground car, at present, adopting is manual dynamic power shift gear box the most widely, vehicle heading and gear are respectively by directional selecting valve and two manually operated valve controls of gear selector valve, be that the directional selecting valve handle is a neutral when being in meta, the directional selecting valve handle is respectively forward gear " F " and retreats retaining " R " when pushing or extracting; In like manner, gear selector valve handle rests on diverse location corresponding I, II, the different gears of III respectively.That is to say; finish vehicle driving control; must control two handles of control gearbox; gas pedal or clutch pedal; brake petal; steering wheel a series of mechanisms such as (or steering tillers); because the down-hole trackless vehicle runs in the relatively narrow and small tunnel usually; its working environment is relatively more abominable, and (dust is big; bend is many; low visibility; the ground inequality); and handle that operator need control and pedal ratio are more (except that the mechanism of above-mentioned control walking; also has tipping bucket; operation mechanisms such as lifting control); usually be in a rush; tired exhausted some misoperations that also occur of getting off of class: as pull wrong handle or step on wrong pedal; cause vehicle to knock the generation of accidents such as miscellaneous equipment or wall; may occur when serious overturning crisis workman life safety.
Summary of the invention
The purpose of this utility model provides a kind of gearbox PLC control gear that adopts automatically controlled manual transmission.
The utility model is to adopt following technological scheme to realize its goal of the invention, a kind of gearbox PLC control gear, it comprises the automatically controlled manual transmission that is connected with gear control electromagnetic valve group, gear control electromagnetic valve group is connected with the PLC controller by program controling module, break-make by each solenoid valve in the program controling module control gear control electromagnetic valve group, the input end of PLC controller is connected with by adding retaining button "+", neutral button " 0 " and subtracting the control knob that retaining button "-" is formed, and control knob is connected with power supply V.
Gear control electromagnetic valve group described in the utility model comprises solenoid valve I, solenoid valve II, solenoid valve III, solenoid valve IV.
Because adopt technique scheme, the utility model has been realized goal of the invention preferably, it is simple in structure, and gearbox direction and gear control can easily realize by 3 buttons that are integrated on the handle, control convenience, safety, reliable.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
As shown in Figure 1, a kind of gearbox PLC control gear, it comprises the automatically controlled manual transmission that is connected with gear control electromagnetic valve group, gear control electromagnetic valve group is connected with the PLC controller by program controling module, break-make by each solenoid valve in the program controling module control gear control electromagnetic valve group, the input end of PLC controller is connected with by adding retaining button "+", neutral button " 0 " and subtracting the control knob that retaining button "-" is formed, and control knob is connected with power supply V.
Gear control electromagnetic valve group described in the utility model comprises solenoid valve I, solenoid valve II, solenoid valve III, solenoid valve IV.
The utility model at first set 3 retainings that advance, 2 retainings that advance, 1 retaining that advances, neutral, reversing 1 retaining, reversing 1 retaining, seven kinds of situations of reversing 1 retaining respectively with gear control electromagnetic valve group in each solenoid valve the work corresponding relation and by the command control of PLC controller by program controling module output.
All must not when electricity when solenoid valve I, solenoid valve II, solenoid valve III, solenoid valve IV, be neutral; Solenoid valve I, solenoid valve II, solenoid valve III get electric 1 retaining that advances that is; Solenoid valve II, solenoid valve III get electric 2 retainings that advance that are; Having only the solenoid valve III to get when electric is 3 retainings that advance.Solenoid valve I, solenoid valve II, solenoid valve IV simultaneously electric for retreat 1 the retaining; Solenoid valve II, solenoid valve IV simultaneously electric for retreat 2 the retaining; Have only the solenoid valve IV to get when electric to retreating 3 retainings.
During use, when the operator touches neutral button " 0 ", the PLC controller write down these data and by program controling module to gear control electromagnetic valve group output order " 0 ", at this moment, solenoid valve I, solenoid valve II, solenoid valve III, solenoid valve IV all must not be electric, correspond to neutral.When operator's shake-up adds retaining button "+", the output order of PLC controller adds 1 again for the instruction of storage before, as being " 0 " before, then output "+1 " this time, and write down these data (cover before data), at this moment, solenoid valve I, solenoid valve II, solenoid valve III get electric, correspond to 1 retaining that advances.So analogize.The output order of PLC controller "+3 ", "+2 ", "+1 ", " 0 ", " 1 ", " 2 ", " 3 " correspond to 3 retainings that advance, 2 retainings that advance, 1 retaining that advances, neutral, reversing 1 retaining, reversing 2 retainings, reversing 3 retainings.And it is corresponding with the work relationship of each solenoid valve in the gear control electromagnetic valve group.
Claims (2)
