Technical field
The present invention relates to engineering Inspection Technique field, belong to a kind of sensing apparatus that loading shovel can be pointed out to contact to earth especially.
Background technology
Loader is construction machinery conventional in construction project, is mainly used in the bulk materials such as shovel dress soil, sandstone, lime, coal, also can makes slight shovel to ore, pan soil etc. and dig operation, has that operating speed is fast, mobility good, operates the advantages such as light.But, model due to car differ and the qualification of driver different, easily occur loading shovel shovel place scoop bad ground, or loading shovel shovel place shallow remaining to some extent problem, thus cause operating efficiency low, even the bad phenomenon of effect out.
Summary of the invention
Namely object of the present invention is to provide a kind of loading shovel to contact to earth sensing apparatus, the object simplifying procedures to reach, improve operating efficiency, improve working effect.
Loading shovel provided by the present invention contacts to earth sensing apparatus, it is characterized in that, comprises balance sensing unit device, signal generation apparatus and alarming signal device; Balance sensing unit device is fixedly mounted on loader vehicle body, and signal generation apparatus and balance sensing unit device link, and signal generation apparatus is connected by wire with alarming signal device.
Described balance sensing unit device is liquid level equilibrium pipe, and fixed in position, on loader vehicle body, has opaque liquid in liquid level equilibrium pipe.
Described signal generation apparatus is made up of photoelectric tube and light emitting source corresponding with it, and the two is arranged in the side of above-mentioned liquid level equilibrium pipe respectively.
Described alarming signal device is at least one in acoustic signal, optical signal, vibration signal, with electric power generating composition electric power loop.
Loading shovel provided by the present invention contacts to earth sensing apparatus, its balance sensing unit device is fixedly mounted on loader vehicle body, touch the end at scraper bowl cause front-wheel pressure relieve instantaneously and lift, when then causing loader body sway, balance sensing unit device acts on signal generation apparatus, make it to send signal, and then control alarm signal and point out driver with sound, luminescence or the mode that shakes, have that perception is sensitive, easy to use, the simple good effect of structure.
Accompanying drawing explanation
Accompanying drawing part discloses specific embodiments of the invention, wherein,
Fig. 1, operating principle schematic diagram of the present invention;
Fig. 2, A portion of the present invention enlarged drawing;
Fig. 3, A portion of the present invention left view.
Detailed description of the invention
As shown in Figure 1, loading shovel provided by the present invention contacts to earth sensing apparatus, comprises balance sensing unit device, signal generation apparatus and alarming signal device.Balance sensing unit device is fixedly mounted on loader vehicle body, in order to sense the inclination of vehicle body.Signal generation apparatus and balance sensing unit device link, and signal generation apparatus is connected by wire with alarming signal device.
In the present embodiment, described balance sensing unit device is liquid level equilibrium pipe 1, and fixed in position, on loader vehicle body, has opaque liquid in liquid level equilibrium pipe.
Described signal generation apparatus is made up of photoelectric tube 2 and light emitting source 3 corresponding with it, and the two is arranged in the side of above-mentioned liquid level equilibrium pipe respectively;
For making above-mentioned liquid level equilibrium pipe still keep rational liquid level when loader vehicle body tilts up or down, the present invention is also provided with liquid level compensator 6, as shown in Figure 2 and Figure 3, comprises weight 6-1, chuck 6-2, clamp 6-3, electromagnet 6-4 and piston rod; Weight is freely sagging, and chuck is fixed on the upper end of weight; The jaw of clamp aims at the card of chuck, and caliper jaw outer end is placed with electromagnet, and there is back-moving spring clamp junction, and when ensureing that electromagnet is not energized, clamp are in open configuration; Piston rod has cylinder bucket 6-6 and cylinder bar 6-5, cylinder bar and chuck fixed connection, can rotate free push-and-pull in cylinder bucket with chuck; Cylinder bucket has fluid infusion mouth, and the infusion port 7 be provided with above-mentioned liquid level equilibrium pipe is communicated with.
Above-mentioned alarming signal device 4 is at least one in acoustic signal, optical signal, vibration signal, forms electric power loop with power supply 5.
For preventing the above-mentioned volatilization of liquid level equilibrium liquid in pipe and entering of dust, above-mentioned liquid level equilibrium pipe adopts closed structure.
In addition, for preventing liquid acutely rocking in pipe in normal traveling, liquid level equilibrium pipe is provided with electromagnetic valve 8, and its control end is connected in above-mentioned electric power loop.What electromagnetic valve adopted is normally closed type, and when switching on power, rear electromagnetic valve is opened.
In the present embodiment, the contact to earth operating principle of sensing apparatus of loading shovel provided by the present invention is such:
When switch 1 is opened, electromagnetic valve is in the closure state that is not energized, and liquid level equilibrium liquid in pipe is divided into two sections, can prevent liquid from acutely rocking because vehicle body rocks; When switch 2 is opened, electromagnet no power, caliper jaw does not block chuck, and weight is swingable, and when switch 2 closes, electromagnet is energized, and caliper jaw blocks chuck, and weight is fixed with chuck.In normal driving process, rise and fall or vibrations with vehicle body, now liquid level compensator work, when vehicle body rocks, weight swings because of Action of Gravity Field, drives chuck to rotate and cylinder bar promotes liquid in cylinder body and makes liquid level equilibrium liquid in pipe keep balance.When carrying out loading work, shut switch 1, then electromagnetic valve is opened, and liquid level equilibrium liquid in pipe is communicated with, and shuts switch 2, and electromagnet is energized, and caliper jaw blocks chuck, and liquid level compensator quits work; Scraper bowl touches the moment end, and front-wheel pressure relieve and lifting, causes loader body sway, liquid level in liquid level equilibrium pipe rises, trigger photoelectric tube because opaque liquid covers light source, cause alarming signal device action and send information, help driver to judge that scraper bowl is to be in state of the tactile end.
