Description
Technical field
The utility model relates to scraper technical field, is specifically related to a kind of scraper hydraulic reservoir depth alarm device.
Background technology
Scraper is the one of mine trackless equipment, is widely used in the digging of underground mine, transport.With the trackless excavating equipment that scraper and self-tipping type fortune ore deposit truck are core, become the main flow of mining technique development at home and abroad.
When after scraper work certain hour, driver all needs regularly to get off to check the oil mass of fuel tank, to ensure the normal work of scraper.Because nothing on this fuel tank is provided with relevant oil level detecting device, when oil pipe, oil pump leakage of oil, scraper driver not easily find, still continuous operation, until when the oil mass in hydraulic reservoir can not meet scraper work, just know fuel tank inner oil shortage, at this moment just start to search leakage of oil point, waste a large amount of hydraulic oil like that, caused unnecessary hydraulic oil waste, also substantially reduce the serviceable life of equipment simultaneously.
Utility model content
For above-mentioned deficiency, the purpose of this utility model is, provides a kind of smart structural design, rationally, simple to operate, and driver can be allowed to learn the scraper hydraulic reservoir depth alarm device whether hydraulic oil leaks in time, easily.
For achieving the above object, technical scheme provided by the utility model is:
A kind of scraper hydraulic reservoir depth alarm device, it comprises power supply, disconnect, warning device, cylindrical shell, upper armature contact, lower fixed contact and float, described cylindrical shell is arranged on the madial wall of fuel tank, and the bottom of this cylindrical shell is positioned at the oil level early warning position of described fuel tank, described lower fixed contact is arranged on the bottom in described cylindrical shell, described float is movably arranged in cylindrical shell, described upper armature contact is arranged on the bottom surface of described float, first electrode of described power supply, disconnect, warning device and being connected successively by wire, second electrode of described power supply is connected with described lower fixed contact by wire.When the non-leakage of oil of fuel tank, float is under the upwards effect of the buoyancy of hydraulic oil, in corresponding drive, armature contact moves up, and then be separated with lower fixed contact, namely armature contact is gone up and lower fixed contact is off state, warning device does not work, when hydraulic fluid leak, namely when the hydraulic oil oil level in fuel tank drops to the oil level early warning position preset, float declines with the decline of hydraulic oil oil level, armature contact is made to contact with lower fixed contact accordingly, namely armature contact is gone up and lower fixed contact is closure state, circuit is path, now warning device, remind operation driver to stop immediately and search leakage of oil point, thus reach the object decreasing hydraulic oil loss.
Improve as one of the present utility model, the bottom surface of described cylindrical shell and fuel tank is perpendicular.
Improve as one of the present utility model, the top and bottom of described cylindrical shell are enclosed construction, and this cylindrical shell is provided with and allows the hydraulic oil in fuel tank flow into oilhole in it.
Improve as one of the present utility model, described disconnect is DC circuit breaker.
Improve as one of the present utility model, described warning device is direct current audible-visual annunciator.
The beneficial effects of the utility model are: the utility model smart structural design, rationally, when leakage of oil causes the hydraulic oil oil level in fuel tank to drop to the oil level early warning position preset, circuit automatic switching on makes warning device work, realize reminding operation driver to stop immediately in time and search the object of leakage of oil point, and then decrease hydraulic oil loss, not only avoid unnecessary waste, save cost, also the stability and safety contributing to scraper is run, and increases the service life; And one-piece construction is simple, simple, convenient, be easy to realize, be beneficial to wide popularization and application.
Below in conjunction with accompanying drawing and embodiment, the utility model is further illustrated.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Embodiment, see Fig. 1, a kind of scraper hydraulic reservoir depth alarm device that the present embodiment provides, it comprises power supply 1, disconnect 2, warning device 3, cylindrical shell 4, upper armature contact 5, lower fixed contact 6 and float 7, described cylindrical shell 4 is arranged on the madial wall of fuel tank 8, and the bottom of this cylindrical shell 4 is positioned at the oil level early warning position of described fuel tank 8, described lower fixed contact 6 is arranged on the bottom in described cylindrical shell 4, described float 7 is movably arranged in cylindrical shell 4, described upper armature contact 5 is arranged on the bottom surface of described float 7, first electrode of described power supply 1, disconnect 2, warning device 3 and being connected successively by wire, second electrode of described power supply 1 is connected with described lower fixed contact 6 by wire.Preferably, make described cylindrical shell 4 perpendicular with the bottom surface of fuel tank 8, to promote the degree of accuracy detecting hydraulic oil oil level, also promote the smoothness that lifting action made by float 7 in cylindrical shell 4 simultaneously.
In the present embodiment, the top and bottom of described cylindrical shell 4 are enclosed construction, and this cylindrical shell 4 is provided with and allows the hydraulic oil in fuel tank 8 flow into oilhole in it.In other embodiment, the top and bottom of this cylindrical shell 4 also can be open structure, the support for arranging lower fixed contact 6 only need be provided with in the lower end of cylindrical shell 4, and the corresponding upper end at cylindrical shell 4 be provided with prevent float 7 from its in the divider that drops out, at this moment, hydraulic oil in fuel tank 8 can from support or and gap between divider and cylindrical shell 4 enter in cylindrical shell 4, same realization makes the inner space of cylindrical shell 4 be connected with the inner space of fuel tank 8.
In the present embodiment, power supply 1 is accumulator, and this power supply 1 can add setting in addition, also can substitute by the accumulator on direct scraper.Preferably, described disconnect 2 is DC circuit breaker.Described warning device 3 is direct current audible-visual annunciator, and have luminescence and sounding effect, alarming effect is more obvious simultaneously.
When fuel tank 8 non-leakage of oil, float 7 is under the upwards effect of the buoyancy of hydraulic oil, in corresponding drive, armature contact 5 moves up, and then be separated with lower fixed contact 6, namely armature contact 5 is gone up and lower fixed contact 6 is off state, warning device 3 does not work, when hydraulic fluid leak, namely when the hydraulic oil oil level in fuel tank 8 drops to the oil level early warning position preset, float 7 declines with the decline of hydraulic oil oil level, armature contact 5 is made to contact with lower fixed contact 6 accordingly, namely armature contact 5 is gone up and lower fixed contact 6 is closure state, circuit is path, now warning device 3, realize reminding operation driver to stop immediately in time and search the object of leakage of oil point, and then decrease hydraulic oil loss, not only avoid unnecessary waste, save cost, also the stability and safety contributing to scraper is run, increase the service life.
The announcement of book and instruction according to the above description, the utility model those skilled in the art can also change above-mentioned embodiment and revise.Therefore, the utility model is not limited to embodiment disclosed and described above, also should fall in the protection domain of claim of the present utility model modifications and changes more of the present utility model.In addition, although employ some specific terms in this instructions, these terms just for convenience of description, do not form any restriction to the utility model.As described in the utility model above-described embodiment, adopt structure same or analogous with it and other device obtained, all in the utility model protection domain.
