Oil shortage monitoring mechanism of rocker arm oil cylinder of drilling machine

Abstract

The invention discloses an oil shortage monitoring mechanism of a rocker arm oil cylinder of a drilling machine. The oil shortage monitoring mechanism comprises an oil cylinder consisting of a rocker arm body, a spherical pull rod, a piston rod and an oil cylinder, wherein a monitoring probe is arranged on the upper surface of the oil cylinder, and is connected with an infrared monitoring emitter and an infrared monitoring receiver; the infrared monitoring receiver is respectively connected with a monitoring display and a PLC; and the PLC is respectively connected with a signal lamp and a speaker.

Description

technical field [0001] The invention relates to an oil shortage monitoring mechanism for an oil cylinder, in particular to an oil shortage monitoring mechanism for a rocker arm oil cylinder of a drilling machine, and belongs to the technical field of machine tool equipment monitoring. Background technique [0002] The rocker cylinder of the drilling machine is an important lubricating part for the oil supply of the rocker. In the existing structure of the rocker cylinder of the drilling machine, it is generally adopted when the hydraulic oil enters the lower abdominal cavity of the cylinder, the clearance of the rocker increases, and the clamping state of the rocker is released. Conversely, when the hydraulic oil enters the large abdominal cavity of the oil cylinder, the running gap of the rocker arm is eliminated. From the above mechanism, it can be seen that if the oil cylinder of the rocker arm is short of oil, the entire mechanical rocker arm cannot work normally. If the ...

Problems solved by technology

[0005] Beneficial effect of the present invention: since the present invention is provided with the monitoring probe in the inner chamber of the oil cylinder, once the oil in the rocker arm oil cylinder is short of oil or the oil in the oil cylinder is less than the set value oil level data in the PLC programmable controller, the monitoring probe will immediately The signal is transmitted to the infrared monitoring transmitter, and the infrared monitoring transmitter is about to transmit the signal to the infrared monitoring receiver, and the infrared monitoring receiver transmits the signal to the monitoring display, signal lamp and speaker respectively. At this time, the display displays data, the signal lamp lights up, and the speaker alarms Inform the rocker arm oil cylinder of oil shortage; the present invention has the advantages of simple structure, convenient disassembly, safety and reliability, good monitoring performance, signal and alarm integration, and effectively overcomes all the existing problems of the existing rocker arm oil cylinder without a monitoring mechanism. Lack of oil in the oil cylinder causes the machine to fail to work normally, and is more likely to cause serious damage to other components
