Abstract
The utility model relates to a protection system for a hydraulic system of a heading machine. The system comprises an oil temperature and oil level integrated sensor, a controller, a display, a contactor and an oil pump motor; the oil temperature and oil level integrated sensor is connected with the controller; the controller is connected with the display; at the same time the controller is also connected with the contactor; and the contactor is connected with the oil pump motor. The oil temperature and oil level integrated sensor transmits an acquired and converted oil temperature and oil level signal to the controller and the controller converts the signal into oil temperature and oil level values and then transmits the values to the display to display. When the oil temperature is high or the oil level is low, the display gives an alarm; and when the oil temperature is excessively high or the oil level is excessively low, the controller outputs a signal to switch off the contactor and a power supply of the oil pump motor is switched off by the contactor to enable the oil pump motor to stop working, so that the hydraulic system stops operating and the aim of protecting the hydraulic system is fulfilled.
Description
Technical field
The utility model relates to the protection of various machinery hydraulic systems, particularly for the protection of tunneling machine hydraulic system.
Background technique
At present, for the machinery that contains hydraulic system, the situation that oil temperature in hydraulic system is too high, oil mass is very few can occur, if in this case, hydraulic system is still moved, and then can cause the major injury to hydraulic system.
Existing solution is, an oil temperature sensor is installed in hydraulic oil container is responsible for detecting oil temperature, a fuel level sensor is installed again is responsible for detecting oil level, with data transmission to a programmable controller, programmable controller is again with data transmission to a liquid crystal display, demonstrate current oil temperature and oil level at display device, thereby reach the purpose of the oil temperature oil level of monitoring hydraulic system.
Problem is, the first, and the means that gather the oil temperature oil level are too complicated.The second, for the monitoring of the oil temperature oil level of hydraulic system, can not determine the operation of stop solution pressing system, and if hydraulic system is not out of service, monitoring does not have the effect of protection hydraulic system so.
The model utility content
The means that gather the oil temperature oil level are too complicated, oil temperature is too high or oil level is crossed deficiency that can not determine the operation of stop solution pressing system when hanging down in order to remedy, and the utility model provides a kind of protective system of tunneling machine hydraulic system.
The utility model is achieved in that this system is comprised of oil temperature oil level integral sensor, controller, display device, contactor and Oil pump electrical machinery.Oil temperature oil level integral sensor is installed in the hydraulic oil container in the hydraulic system, the signal output part of oil temperature oil level integral sensor is connected with controller by shielded cable, controller is connected with display device by shielded cable, be connected with contactor by shielded cable with Time Controller, then contactor is connected with Oil pump electrical machinery by cable.Oil temperature oil level integral sensor detects oil temperature and the oil level of the hydraulic oil container in the hydraulic system, then be converted to signal and transfer to controller through its signal output part, controller is converted to oil temperature oil level numerical value with this signal, then these numerical value is transferred to display device and shows.When higher or oil level was on the low side when oil temperature, display device was reported to the police; Too high or oil level is crossed when low when oil temperature, and controller output signal disconnects contactor, cuts off the power supply of Oil pump electrical machinery by contactor, Oil pump electrical machinery is quit work, thereby make hydraulic system out of service.
The beneficial effects of the utility model are, have adopted oil temperature oil level integral sensor, and are simpler, quick than traditional approach; Simultaneously can be in oil temperature higher or oil level alarm on the low side, the too high or oil level of oil temperature is crossed the operation of stop solution pressing system real when low, thereby reaches the purpose of protection hydraulic system.
Description of drawings
Accompanying drawing is the control structure figure of the protective system of a kind of tunneling machine hydraulic system of the utility model.
Among the figure, 1, oil temperature oil level integral sensor; 2, controller; 3, display device; 4, contactor; 5, Oil pump electrical machinery.
Embodiment
In this system, oil temperature oil level integral sensor (1) links to each other with controller (2) by cable, controller (2) links to each other with display device (3) by cable, same Time Controller (2) links to each other with contactor (4) by cable, and contactor (4) links to each other with Oil pump electrical machinery (5) by cable.
Oil temperature oil level signal after oil temperature oil level integral sensor will gather, change transfers to controller, and controller is converted to oil temperature oil level numerical value with this signal, then these numerical value is transferred to display device and shows.When higher or oil level was on the low side when oil temperature, display device was reported to the police; Too high or oil level is crossed when low when oil temperature, and controller output signal disconnects contactor, cuts off the power supply of Oil pump electrical machinery by contactor, Oil pump electrical machinery is quit work, thereby make hydraulic system out of service.This system has adopted oil temperature oil level integral sensor, and is simpler, quick than traditional approach; Simultaneously can be in oil temperature higher or oil level alarm on the low side, the too high or oil level of oil temperature is crossed the operation of stop solution pressing system real when low, thereby reaches the purpose of protection hydraulic system.
Claims (1)
