Description
Technical Field
The utility model relates to a product detection equipment technical field especially relates to a hydraulic pressure dish outage of stopping and low alarm device of oil pressure.
Background
The medium hydraulic disc brake device consists of three parts: the brake actuator, the hydraulic station and the operating platform are connected by hydraulic pipelines. The hydraulic station is a power source and provides necessary hydraulic power for the actuator. The hydraulic station has two plunger pumps, one for use and one for standby, and the plunger pumps are connected with a motor. The motor starting switch is of a self-resetting type, when the hydraulic station is powered off suddenly, the hydraulic station stops working, and even if the hydraulic station is powered on again, if an operator does not start a motor button, the hydraulic station still cannot work. The instable field voltage often causes instantaneous power failure of the power grid. After the power failure, an operator cannot find the failure in time, and the brake failure accident is easy to cause.
At present, a system pressure of a hydraulic station is not provided with a real-time monitoring alarm device, an operator cannot find that the oil pressure is low in time, the braking force is reduced, and production accidents are easy to happen.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome the not enough of above-mentioned technique, and provide a hydraulic pressure dish outage and low alarm device of oil pressure.
The utility model discloses a realize above-mentioned purpose, adopt following technical scheme: the utility model provides a hydraulic pressure dish power off and low alarm device of oil pressure which characterized in that: a first explosion-proof control box is fixed on the outer side of the hydraulic station shell, a wireless transmitting circuit board and a wireless transmitter connected with the wireless transmitting circuit board are arranged in the first explosion-proof box, and current transformers are respectively installed at the lower ports of main contactors of two motors in the hydraulic station shell and connected with the wireless transmitting circuit board through leads;
a wireless pressure sensor is arranged on a pressure pipeline of a hydraulic station system, and is used for detecting a system pressure signal in real time and sending the signal outwards;
the second explosion-proof control box is arranged on the driller's stand, a display screen, a receiving circuit board, a control button, a wireless receiver and an audible and visual alarm are arranged on the second explosion-proof control box, the wireless receiver receives two motor quantity signals and a hydraulic station system pressure signal, the display screen displays a system pressure value and a motor start-stop signal in real time, and when the hydraulic station system pressure is lower than an alarm set value, oil pressure low alarm information is sent; when two motors stop simultaneously, the default system is powered off, power-off alarm information is sent out, and the control button is used for eliminating the alarm information.
The beneficial effects of the utility model are that overcome through this device because the incident that the outer net outage can not in time discover to cause, the low alarm device of system pressure further ensures hydraulic means's security simultaneously, even the outer net outage probably causes hydraulic pressure station system pressure low because the oil pump motor damages. The added oil pressure monitoring device of the wireless system further ensures the safety of a brake system and avoids major safety accidents caused by brake failure.

Detailed Description
Spatially relative terms such as "above … …", "above … …", "above … …", "above", and the like, may be used herein for ease of description to describe the spatial relationship of one feature or characteristic to another feature or characteristic as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, devices described as "above" or "on" other devices or configurations would then be oriented "below" or "under" the other devices or configurations. Thus, the exemplary term "above … …" can include both an orientation of "above … …" and "below … …". The device may be otherwise variously oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.
As shown in figure 1, a hydraulic pressure disc braking and power-off and oil pressure low alarm device is characterized in that a first explosion-proof control box 4 is fixed on the outer side of a hydraulic station shell, and a circuit board 5 and a wireless transmitter are arranged in the explosion-proof control box 4. A current transformer 9 is respectively installed at the lower ports of main contactors of two motors 8 in an electric cabinet 7 of the hydraulic station, and the wiring of the current transformer 9 is led to an explosion-proof control box circuit board 5. When the motor is started, the current transformer 9 detects a current signal and sends the current signal to the circuit board 5, and the circuit board 5 converts an analog quantity signal into a digital quantity signal through the programming of the single chip microcomputer and sends the signal through the wireless transmitter.
A wireless pressure sensor 6 is arranged on a pressure line of a hydraulic station system, and is used for detecting a system pressure signal in real time and sending the signal outwards.
As shown in fig. 2, the driller's stand is provided with a second explosion-proof control box 11, which is composed of a display screen 3, a circuit board 10, a control button 12, a wireless receiver 1 and an audible and visual alarm 2. The wireless receiver 1 receives signals of the number of the two motors and pressure signals of a hydraulic station system, and the display screen displays the pressure value of the system and the start and stop signals of the motors in real time. When the system pressure of the hydraulic station is lower than the alarm set value, sending out oil pressure low alarm information; when the two motors 8 stop simultaneously, the default system is powered off, and power-off alarm information is sent out. If the hydraulic station is normally closed manually, power-off alarm information can be sent out, and the driller can perform silencing only by pressing a silencing button. The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
