Description
Technical field
The present invention relates to the engineering Inspection Technique field, belong to especially a kind of sensing apparatus that can point out loading shovel to contact to earth.
Background technology
Loader is construction machinery commonly used in the construction project, is mainly used in the bulk materials such as shovel dress soil, sandstone, lime, coal, also can slightly shovel work such as ore, pan soil and dig operation, has that operating speed is fast, mobility good, operates the advantages such as light.But, because the qualification difference that the model of car differs and drives the driver, occur easily loading shovel shovel place bad ground of scoop, perhaps loading shovel shovel place shallow remaining to some extent problem, thereby cause operating efficiency low, even the bad phenomenon of effect out.
Summary of the invention
Purpose of the present invention namely is to provide a kind of loading shovel sensing apparatus that contacts to earth, and simplifies procedures, improves operating efficiency to reach, improves the purpose of working effect.
The loading shovel provided by the present invention sensing apparatus that contacts to earth is characterized in that, comprises balance sensing unit device, signal generation apparatus and alarming signal device; The balance sensing unit device is fixedly mounted on the loader vehicle body, signal generation apparatus and the interlock of balance sensing unit device, and signal generation apparatus is connected by wire with alarming signal device.
Described balance sensing unit device is the liquid level equilibrium pipe, and fixed in position has opaque liquid in the liquid level equilibrium pipe on the loader vehicle body.
Described signal generation apparatus by photoelectric tube and with it corresponding light emitting source consist of, the two is arranged in respectively a side of above-mentioned liquid level equilibrium pipe.
Described alarming signal device is at least a in acoustic signal, optical signal, the vibration signal, with the electric power generating composition electric power loop.
The loading shovel provided by the present invention sensing apparatus that contacts to earth, its balance sensing unit device is fixedly mounted on the loader vehicle body, touching the moment end at scraper bowl causes the front-wheel pressure relieve and lifts, when then causing the loader body sway, the balance sensing unit device acts on signal generation apparatus, make it to send signal, and then the control alarm signal points out the driver with sound, mode luminous or vibrations, have perception sensitivity, good effect easy to use, simple in structure.
Description of drawings
Accompanying drawing partly discloses specific embodiments of the invention, wherein,
Fig. 1, operating principle schematic diagram of the present invention;
Fig. 2, A of the present invention section enlarged drawing;
Fig. 3, A of the present invention section left view.
The specific embodiment
As shown in Figure 1, the loading shovel provided by the present invention sensing apparatus that contacts to earth comprises balance sensing unit device, signal generation apparatus and alarming signal device.The balance sensing unit device is fixedly mounted on the loader vehicle body, in order to the inclination of sensing vehicle body.Signal generation apparatus and the interlock of balance sensing unit device, 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 has opaque liquid in the liquid level equilibrium pipe on the loader vehicle body.
Described signal generation apparatus by photoelectric tube 2 and with it corresponding light emitting source 3 consist of, the two is arranged in respectively a side of above-mentioned liquid level equilibrium pipe;
For making above-mentioned liquid level equilibrium pipe still keep rational liquid level when the loader vehicle body tilts up or down, the present invention also is provided with liquid level compensator 6, such as Fig. 2, shown in 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 is aimed at the card of chuck, and the caliper jaw outer end is placed with electromagnet, and there is back-moving spring the clamp junction, and clamp were not in open configuration when the assurance electromagnet was switched on; Piston rod has cylinder bucket 6-6 and cylinder bar 6-5, and cylinder bar and chuck fixed connection can rotate free push-and-pull in the cylinder bucket with chuck; The cylinder bucket has the fluid infusion mouth, and the infusion port 7 that is provided with above-mentioned liquid level equilibrium pipe is communicated with.
Above-mentioned alarming signal device 4 is at least a in acoustic signal, optical signal, the vibration signal, consists of electric power loops 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 middle liquid acutely the rocking in pipe of normally travelling, be provided with electromagnetic valve 8 at the liquid level equilibrium pipe, its control end is connected in the above-mentioned electric power loop.What electromagnetic valve adopted is normally closed type, when the plugged 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 was opened, electromagnetic valve was in the closure state of not switching on, and the liquid level equilibrium liquid in pipe is divided into two sections, can prevent that liquid from rocking because vehicle body rocks acutely; When switch 2 is opened, the electromagnet no power, caliper jaw does not block chuck, and weight can freely swing, during switch 2 closure, the electromagnet energising, caliper jaw blocks chuck, and weight is fixed with chuck.In normal driving process, rise and fall or vibrations with vehicle body, liquid level compensator work this moment, weight swings because of Action of Gravity Field when vehicle body rocks, and drives the chuck rotation and the cylinder bar promotes that liquid makes the liquid level equilibrium liquid in pipe keep balance in the cylinder body.When loading work, shut switch 1, then electromagnetic valve is opened, and the liquid level equilibrium liquid in pipe is communicated with, and shuts switch 2, the electromagnet energising, caliper jaw blocks chuck, and liquid level compensator quits work; Scraper bowl touches the moment end, and front-wheel pressure relieve and lifting causes the loader body sway, liquid level in the liquid level equilibrium pipe rises, trigger photoelectric tube because opaque liquid covers light source, cause alarming signal device and move and send information, help the driver to judge that scraper bowl is to be in state of the tactile end.
