The distance setting type uses this to realize detection.
Fig. 6 shows the boom in the folded state, because the boom 1 is in the folded state, the infrared light emitted by the light projecting part of the third light projector 13 is reflected to the light receiving part of the third light projector 13 by the boom partition 2, and the signal line 5 feeds back the signal to the pump truck main control system, at this time, the optical sensing system forms a closed loop, and the main control system determines that the boom is in the non-working state (folded state) at this time, and can perform the support leg retraction and other actions.

The embodiment of the utility model provides a pair of photoelectric sensing detection device detects drawing in and the expansion state of cantilever crane through photoelectric signal's conversion and break-make, compares with traditional detection mechanism, has following advantage:
1) the arm itself is not in contact with the detection structure. The traditional detection structure, namely various forms of proximity switches, always contact the arm support, sense mechanical pressure and then convert the mechanical pressure into an electric signal so as to judge the state of the arm support. The embodiment of the utility model provides a then detect through the break-make of light-signal of telecommunication, the cantilever crane does not have any contact with detection device and can reach the purpose, has just so avoided in long-term use, and the cantilever crane influences proximity switch's contact pressure, then influences proximity switch's precision gently, then leads to proximity switch to damage seriously. The device can eliminate the problem that the proximity switch fails due to long-term contact between the arm support and the proximity switch in the traditional device theoretically, and greatly prolongs the service life of the detection device.
2) The use and the maintenance are convenient. The device and the accessory structural parts are simple, and the device and the accessory structural parts are only fixed by screws during installation, and more importantly, the device does not need to be specially debugged. Compared with the traditional detection device, the device only needs to adjust the heights of the light projector and the reflecting plate when being installed for the first time, and does not need to adjust the heights of the light projector and the reflecting plate subsequently; the mechanical pressure type proximity switch needs to perform relatively accurate debugging on the stroke, and along with long-term use and sinking of the arm support, the stroke of the proximity switch needs to be checked and adjusted at intervals, so that the maintenance cost is increased invisibly.
3) Low failure rate. At present, because the traditional mechanical pressure contact type proximity switch has different detection principles, the proximity switch must be in contact with an arm support, and cannot be well protected. The working environment of the pump truck is generally not good, and the pump truck is in the working condition of pollution such as dust, oil stain and concrete for a long time, which is also an important reason for causing the proximity switch to break down and causing damage. This device has then adopted double-deck protection, and the protection level of at first product itself just reaches IP67, has still designed the protection casing in addition, can effectively keep apart dust, greasy dirt, concrete pollution, has reduced the fault rate, has prolonged life indirectly.
4) The application range is wide. The three structural types are different in applicable occasions, and the most suitable structural type can be selected according to needs, so that the economy is better, and the cost is saved.
It should be clear that the embodiments in this specification are described in a progressive manner, and the same or similar parts in the embodiments are referred to each other, and each embodiment focuses on the differences from the other embodiments. The present invention is not limited to the specific steps and structures described above and shown in the drawings. Also, a detailed description of known process techniques is omitted herein for the sake of brevity.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be regarded as the protection scope of the present invention.
