The stroke control device is simple in structure, has low cost, and can adapt to non-alternating-current power supply occasions effectively.
Description
Technical field
The utility model relates to travel control device.
Background technology
Common, travel control device adopts alternating current control usually, needs a whole set of complicated circuit element and stable alternating voltage.But for the Stroke Control of mini-plant with under the condition that AC power is not provided, above-mentioned Stroke Control mode has very big drawback.
Summary of the invention
For complex structure, the cost height that overcomes existing travel control device, the deficiency that can not adapt to the AC-less power occasion, the utility model provide a kind of simple in structure, cost is low, can effectively adapt to the direct current motor type trigger-type travel control device of AC-less power occasion.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of direct current motor type trigger-type travel control device, comprise the direct current machine of the object action that drives drive cycle linear reciprocating motion and in order to be installed in the frizzen on the object, described direct current machine is connected with elevating mechanism, above described frizzen, be provided with first travel switch, the below of described frizzen is provided with second travel switch, described first travel switch and the interlock of second travel switch, described first travel switch and second travel switch include normally-closed contact and normally opened contact, one end of the normally-closed contact of described first travel switch and normally opened contact all is connected with the first input end of direct current machine, one end of the normally-closed contact of described second travel switch and normally opened contact all is connected with second input of direct current machine, the other end of the other end of the normally-closed contact of described first travel switch and the normally opened contact of second travel switch all is connected with the positive pole of DC power supply, and the other end of the other end of the normally opened contact of described first travel switch and the normally-closed contact of second travel switch all is connected with the negative pole of DC power supply.
Further, the controlled bar of the controlled bar of described first travel switch and second travel switch is connected by connecting line.Certainly, also can adopt other modes to link.
Further again, described controlled bar is the magnetic metal bar, is provided with the top set magnet in order to the position-sensing switch state above described first travel switch.
Further, described elevating mechanism is the pinion and-rack elevating mechanism, on the output shaft of described direct current machine gear is installed, described gear and tooth bar engagement, and described tooth bar is fixedlyed connected with described object.Certainly, also can adopt other elevating mechanisms.
Technical conceive of the present utility model is: described frizzen at preceding two travel switches of the baton of stirring lower stroke switch all in the raw.Under this state, two described object and frizzens that carry out the cycle linear reciprocating motion of travel switch control move to the direction of stirring the motion lower stroke switch.
During initial condition, motor changes (supposing it is forward) to a direction, makes object move up; After touching upper stroke switch (being assumed to be travel switch 1), by this circuit motor reverse rotation, object moves down.Simultaneously, because top set magnet sucks the rod that touches of upper stroke switch, make that object continues to move downward, make circuit be returned to reset condition up to touching lower stroke switch, motor just changes once more, finishes a period of motion.
Value of the present utility model mainly shows: the utility model is simple and reasonable, and production cost is low, can finish the Stroke Control of mini-plant and the Stroke Control of equipment under the condition that AC power is not provided.
Description of drawings
Fig. 1 is the schematic diagram of direct current motor type trigger-type travel control device.
Fig. 2 is the circuit connection diagram of two travel switches.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
See figures.1.and.2, a kind of direct current motor type trigger-type travel control device, comprise in order to the direct current machine 6 of the object of drive cycle linear reciprocating motion action with in order to be installed in the frizzen 2 on the object, described direct current machine 6 is connected with elevating mechanism, above described frizzen 2, be provided with first travel switch 4, the below of described frizzen 2 is provided with second travel switch 1, described first travel switch 4 and 1 interlock of second travel switch, described first travel switch 4 and second travel switch 1 include normally-closed contact and normally opened contact, one end of the normally-closed contact of described first travel switch 4 and normally opened contact all is connected with the first input end of direct current machine 6, one end of the normally-closed contact of described second travel switch 1 and normally opened contact all is connected with second input of direct current machine 6, the other end of the other end of the normally-closed contact of described first travel switch 4 and the normally opened contact of second travel switch 1 all is connected with the positive pole of DC power supply, and the other end of the other end of the normally opened contact of described first travel switch 4 and the normally-closed contact of second travel switch 1 all is connected with the negative pole of DC power supply.
The controlled bar of described first travel switch 4 is connected by connecting line with the controlled bar of second travel switch 1.Certainly, also can adopt other modes to link.
Described controlled bar is the magnetic metal bar, is provided with the top set magnet 5 in order to the position-sensing switch state above described first travel switch 4.
Described elevating mechanism is the pinion and-rack elevating mechanism, on the output shaft of described direct current machine gear is installed, described gear and tooth bar engagement, and described tooth bar is fixedlyed connected with described object.Certainly, also can adopt other elevating mechanisms.
The course of work of present embodiment is: described frizzen at preceding two travel switches of the baton of stirring upper stroke switch 4 all in the raw.Under this state, two described object and frizzens that carry out the cycle linear reciprocating motion of travel switch control move to the direction of stirring motion upper stroke switch 4.
During initial condition, direct current machine changes (supposing it is forward) to a direction, makes object move up; After touching first travel switch 4, the controlled bar of first travel switch 4 and second travel switch 1 is upwards swing all, the wherein controlled bar of first travel switch 4 and 5 adhesives of top set magnet, the operating state of two travel switches of maintenance; Please refer to accompanying drawing 2, after the controlled bar action, normally-closed contact originally becomes off state, and normally opened contact originally becomes closure state, according to the control procedure of this circuit diagram, has realized the motor reverse rotation, and object begins to move down.Simultaneously, because top set magnet 5 sucks the rod that touches of upper stroke switch 4, make that object continues to move downward, touch lower stroke switch 1 up to frizzen 2, the controlled bar of lower stroke switch 1 moves down, and the controlled bar that drives upper stroke switch 4 separates with top set magnet 5, makes circuit return to reset condition, motor just changes once more, finishes a period of motion.
