Abstract
The utility model relates to a hydraulic equipment detecting device, which comprises a signal processor, a sensor A, a sensor B, and a human-machine interface, wherein the sensor A and the sensor B are respectively arranged in two different positions of a piston rod of a hydraulic cylinder; and one end of the signal processor is respectively connected with the sensor A and the sensor B, and the other end of the signal processor is connected with the human-machine interface. The hydraulic equipment detecting device disclosed by the utility model has a simple structure and is convenient to use, and the failure rate of equipment is effectively reduced.
Description
Technical field
The utility model relates to a kind of supervisory device, particularly relates to a kind of hydraulic equipment detection device.
Background technique
Steel pull-out machine in the large-scale factory walking beam furnace is hydraulic proportion valve control, oil hydraulic cylinder action drive external agency with the hot continuous casting blank movement to step rate, hydraulic cylinder travel detects with the external position transducer, testing signal turns back in the control system, form the closed loop control of steel pull-out machine operating position, present oil hydraulic cylinder detection device generally adopts single-sensor, sensor just is installed on the piston rod of steel pull-out machine oil hydraulic cylinder, because the work on the spot environment is more abominable, sensor needs continuous operation, in case sensor breaks down, will influence the accuracy that detects data, serious meeting causes steel billet adhesion on the step rate, more need stop during emat sensor producing, and has influenced manufacturing efficiency greatly.
Summary of the invention
The utility model has overcome deficiency of the prior art, provides a kind of simple in structure, easy to use, the hydraulic equipment detection device of being convenient to safeguard.
In order to address the above problem, the utility model by the following technical solutions:
A kind of hydraulic equipment detection device comprises signal processor, sensors A, sensor B and man-machine interface, and sensors A and sensor B are installed in respectively on two diverse locations of hydraulic cylinder piston rod; Signal processor one end is connected with sensor B with sensors A respectively, and an end is connected with man-machine interface.
Compared with prior art, the beneficial effects of the utility model are:
The utility model reasonable in design is installed two sensors on oil hydraulic cylinder, two sensors can be standby each other, in case one of them breaks down, another sensor can normally detect, and guarantees carrying out smoothly of production, has reduced the security incident rate.
Description of drawings
Fig. 1 is the utility model structured flowchart.
Embodiment
A kind of hydraulic equipment detection device as shown in Figure 1, comprises signal processor, sensors A, sensor B and man-machine interface, and sensors A and sensor B are installed in respectively on two diverse locations of hydraulic cylinder piston rod; Signal processor one end is connected with sensor B with sensors A respectively, and an end is connected with man-machine interface.
During production, signal processor reads the detection data of two sensors and outputs to the enterprising line number value of man-machine interface and shows.2 position transducers of design are selected window on man-machine interface.Two sensors can be selected arbitrarily, switch in the picture, and selecteed sensor participates in oil hydraulic cylinder control as master reference, and another sensor is a backup sensors, does not participate in steel pull-out machine control, only participates in the sensor values comparing function; Signal processor can continuous uninterrupted the detection numerical value of two sensors relatively; when 2 absolute values that detect numerical difference between during greater than 10mm; output alarm flicker on man-machine interface; remind operator and attendant to note; have a sensor to go wrong, the operator can switch on another sensor by the man-machine interface window hydraulic cylinder travel is still carried out position closed loop control, and equipment is not shut down; save the accident treatment time, satisfy and produce actual demand.
