Abstract
The invention relates to a built-in engineering machinery slewing bearing structure, which comprises seat rings, upper shaft washers, lower shaft washers, and column rolling bodies, wherein each seat ring is provided with two upper rolling paths, two lower rolling paths, and a side rolling path; the column rolling bodies are placed in the upper rolling paths, the lower rolling paths, and side rolling paths. The structure has the innovation points that an upper cavity and a lower cavity are formed in the upper surface and the lower surface of each seat ring respectively, upper cavities are communicated with lower cavities through through-holes, emitters of photoelectric sensors are embedded in the upper cavities, and connection ports of the photoelectric sensors are mounted inside the lower cavities; a plurality of reflecting plates corresponding to positions of the emitters are distributed on the upper shaft washers; each seat ring is provided with a circle of ring-shaped dustproof bulges, and a dustproof seal ring matched with the ring-shaped dustproof bulges is embedded in each upper shaft washer. The structure can utilize signals to conduct control or software limitation on engineering machinery position; the using is more convenient; dustproof structures improve the dustproof effect, and meanwhile, limit the photoelectric sensors in spaces not affected by light disturbance, so that the photoelectric sensors are ensured to be able to work normally.
Description
Technical field
The present invention relates to a kind of bearing, particularly a kind of built-in engineering machinery pivoting support structure.
Background technique
Engineering machinery is the important component part of Chinese equipment manufacturing industry.Put it briefly, the necessary mechanized equipment of comprehensive mechanized construction engineering that all restoration in earth-rock construction engineerings, pavement construction and maintenance, flowing type lifting handling operation and various construction engineering are required, be called engineering machinery.It is mainly used in national defense construction engineering, communications and transportation construction, the fields such as the raw and semifinished materials industries construction such as energy industry construction and production, mine and production, agriculture, forestry, water conservancy construction, industry and civil building, urban construction, environmental protection.
Pivoting support is the nearly 40 years novel mechanical component that worldwide rise gradually, in engineering machinery, be widely used, it has the formations such as Internal and external cycle, rolling element, and along with developing rapidly of engineering machinery, its various performances, functional requirement to bearing is also more and more higher.

Summary of the invention
The technical problem to be solved in the present invention be to provide a kind of can be to the seat ring of pivoting support, the built-in pivoting support of engineering machinery that the blowout patche relative position detects.
For solving the problems of the technologies described above, technological scheme of the present invention is: a kind of built-in engineering machinery pivoting support structure, comprise seat ring, upper blowout patche, lower blowout patche and cylinder rolling element, on seat ring, evenly be drilled with the seat ring mounting hole that distributes ringwise and connect the upper and lower end face of seat ring; Upper and lower blowout patche is the ladder tubular structure with large and small end, between upper blowout patche and seat ring, forms raceway on twice, between lower blowout patche and seat ring, forms raceway under twice, between the outer side surface of seat ring side and upper and lower blowout patche, forms one and sidewinders; Described upper and lower, place the cylinder rolling element in sidewindering; Its innovative point is: the upper and lower surface of described seat ring has a upper plenum and cavity once, between upper and lower cavity, be communicated with by through hole, the transmitter of the embedded light point sensor of upper plenum, the photoelectric sensor Wiring port is installed in lower cavity, and this photoelectric sensor Wiring port is connected with the photoelectric sensor transmitter by the datawire that passes through hole; The large end lower end surface of described upper blowout patche is evenly distributed with some tapped holes ringwise, and the tapped hole internal thread connects reflecting plate, and this reflecting plate is the hexagon lag bolt that an end has reflective surface; The centre distance of described tapped hole and upper blowout patche axis equals the centre distance of upper plenum and seat ring axis; The upper-end surface that described seat ring is positioned at the upper plenum outside has the dustproof projection of a ring shape, and a dust-proof seal ring is inlayed in the large end outer ring of described upper blowout patche, and the outer end of this dust-proof seal ring props up the upper-end surface of seat ring and is positioned at the dustproof protruding radial outside of annular.
The invention has the advantages that: the photoelectric sensor transmitter is installed on seat ring, and reflecting plate is set on upper blowout patche, utilizing light source that transmitter sends to be launched plate reflects and is received by the light receiving device in built-in transmitter, in case reflecting plate leaves directly over transmitter, light receiving device can not receive the light time, photoelectric sensor is switch controlling signal of action output just, upper blowout patche constantly drives emitting board and moves and then make the continuous output pulse signal of photoelectric sensor, and then can utilize this signal to carry out the control of engineering machinery position, perhaps soft spacing as engineering machinery, use convenient.
The dustproof projection of annular is set on seat ring, and coordinates with the dust-proof seal ring on upper blowout patche, when improving dust-proof effect, photoelectric sensor is limited in a space that is not subjected to the light interference, guarantee that photoelectric sensor can work.
