Abstract

The utility model discloses a digital electric-hydraulic pusher. The digital electric-hydraulic pusher comprises a hydraulic cylinder, a bidirectional combination pump is arranged at the rear end of the hydraulic cylinder, the hydraulic cylinder is communicated with the bidirectional combination pump through an oil inlet pipe and an oil outlet pipe, the hydraulic cylinder and the bidirectional combination pump are both arranged inside an oil tank, the front end of the hydraulic cylinder stretches out of the oil tank, the bidirectional combination pump is connected with a coupler, the coupler is connected with a servo motor, and the servo motor is connected with a driving device and then is connected with a PLC. According to the digital electric-hydraulic pusher, the PLC outputs a signal to the stepping driving device through a program, the output signal of the PLC is converted by the stepping driving device and then is transmitted to the stepping motor, the stepping motor converts the received electric pulse signal into angular displacement, the stepping motor rotates together with the bidirectional combination pump through the coupler, the pressure energy generated by the rotation of the bidirectional combination pump is transmitted to the hydraulic cylinder, and then the movement of the hydraulic cylinder is achieved. The digital electric-hydraulic pusher has the advantages that the digitization of a traditional hydraulic cylinder is achieved and the improvement of the traditional hydraulic technique is promoted.

Description

A kind of digital electro-hydraulic push rod
Technical field
The utility model relates to a kind of digital electro-hydraulic push rod, belongs to the hydraulic equipment technical field.
Background technique
The electric current push rod is a kind of straight journey actuator of mechanical-electrical-hydraulic integration, and being applicable to needs the reciprocating sliding campaign, and can carry out concentrating or program control of remote high-altitude and dangerous area, is widely used in industries such as metallurgy, electric power mine, building.Because the electric current pusher structure is complicated, it is fragile that existing Electrohydraulic push rod exists the control valve member, thus the defective that causes whole Electrohydraulic push rod to break down even damage.
The model utility content
The purpose of this utility model is to provide a kind of digital electro-hydraulic push rod, reduces the use amount of various control valve members in the Electrohydraulic push rod, and the simplification system forms, and improves reliability, and realizes digitizing, the automation of conventional cylinder promoting the conventional hydraulic development of technology.
To achieve these goals, the technical solution of the utility model is: a kind of digital electro-hydraulic push rod, comprise oil hydraulic cylinder, described oil hydraulic cylinder rear end arranges two-way combined pump, there is the turnover oil pipe to be connected, described oil hydraulic cylinder and two-way combined pump arrange fuel tank outward, oil hydraulic cylinder and two-way combined pump all are coated in the fuel tank, the front end of oil hydraulic cylinder stretches out fuel tank, described two-way combined pump connects coupling, described coupling is connected with actuating motor, and described actuating motor is connected with driver, and described driver meets PLC can compile controller.
Further, described fuel tank front end arranges guide sleeve, is the guiding of oil hydraulic cylinder, and locking nut is set on the guide sleeve, guide sleeve is locked on the flange of fuel tank front end.
Further, described coupling arranges coupling guard outward, is fixed on the flange of fuel tank rear end.
Further, described coupling guard can fall in the oil-feed tank.
Further, described actuating motor is step-servo motor, and described driver is step actuator.
Digital electro-hydraulic push rod of the present utility model, PLC can compile controller and output signal to step actuator by programming, step actuator is passed to stepper motor after the output signal of PLC is transformed, stepper motor is converted into angular displacement to the electrical pulsing signal that receives, stepper motor rotates with two-way combined pump by coupling like this, and two-way combined pump rotates and has produced pressure and can be transported to oil hydraulic cylinder, realizes the action of oil hydraulic cylinder; Stepper motor can be compiled controller by PLC and can realize rotating and reverse, and two-way combined pump can realize also that under the drive of stepper motor oil inlet and outlet exchanges, thereby realize the to-and-fro motion of oil hydraulic cylinder, but also can realize the stepless speed regulation performance of any position of oil hydraulic cylinder by the different operation programming of PLC.Digital electro-hydraulic push rod of the present utility model has reduced the use amount of various control valve members in traditional Electrohydraulic push rod, has simplified system's composition, has improved reliability, and realizes conventional cylinder digitizing, automation, has promoted the conventional hydraulic development of technology.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
The utility model is further described below in conjunction with accompanying drawing and specific embodiment.
As shown in Figure 1, digital electro-hydraulic push rod of the present utility model, comprise oil hydraulic cylinder 6, described oil hydraulic cylinder 6 rear ends arrange two-way combined pump 5, there is turnover oil pipe 9 to be connected, described oil hydraulic cylinder 6 and the two-way combined pump 5 outer fuel tanks 8 that arrange, oil hydraulic cylinder 6 and two-way combined pump 5 all are coated in the fuel tank 8, the front end of oil hydraulic cylinder 6 stretches out fuel tank 9, described two-way combined pump 5 connects coupling 4, described coupling 4 is connected with actuating motor 3, and described actuating motor 3 is connected with driver 2, and described driver 3 connects PLC and can compile controller 1.
Described fuel tank 8 front ends arrange guide sleeve 10, for oil hydraulic cylinder 6 guiding, locking nut 11 are set on the guide sleeve 10, and guide sleeve 10 is locked on the flange of fuel tank 8 front ends.
Outside the described coupling 4 coupling guard 7 is set, is fixed on the flange of fuel tank 8 rear ends.
Described coupling guard 7 can fall in the oil-feed tank 8.
Described actuating motor 3 is step-servo motor, and described driver 2 is step actuator.
The technical solution of the utility model is not limited to the restriction of above-mentioned specific embodiment, and every technology distortion of making according to the technical solution of the utility model all falls within the protection domain of the present utility model.
