Description
Technical field
The utility model belongs to tower crane apparatus field, especially relates to a kind of tower crane bearing.
Background technology
The main power source of tower machine and hydraulic lifting power supply are directly connected to operator's compartment switch case by cable, and cable is through undersetting, swing type mechanism and upper bracket.Because part more than swing type mechanism is rotary operation mode centered by tower body line of centers, therefore cable can produce torsion.And the cable in undersetting wire conduit also and then can rotate along with the rotation of tower crane in wire conduit, cable and wire conduit upper end rub.Because long-term the coming and going of cable is reversed, there will be cable and rubbed by wire conduit, cause the electro-insulating rubber on cable to break, thus cause cable premature aging, fracture, short circuit etc.After long-time use, there is serious potential safety hazard in operation field.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of tower crane bearing being provided with cable protecting device, causes to overcome due to long-term round torsion of cable the problem that the electro-insulating rubber of cable breaks.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of tower crane bearing, comprise undersetting, gear ring backing plate and fender guard, described protection-gear comprises cable anti-cutting cover and deep groove ball bearing, described undersetting is box stand, on it, lower surface is respectively provided with a manhole, described two manhole centers of circle on the same line, described gear ring backing plate is annular, outside the manhole being enclosed within described undersetting upper surface, and be bolted with described undersetting upper surface, the manhole of described undersetting lower surface is provided with expanded metal lath, described expanded metal lath lower surface is provided with wire guide plate, cable runs through described wire guide plate and described expanded metal lath by wire successively pipe, the open end that described wire conduit passes described expanded metal lath overlaps through being connected with described cable anti-cutting, described deep groove ball bearing be fixed on be positioned at described wire conduit open end inside.
Further, described cable anti-cutting cover is back taper.
Further, described expanded metal lath is provided with open channel, and described open channel is connected with climbing support.
Further, also reinforced rib is provided with between the upper and lower surface of described undersetting.
The advantage that the utility model has and good effect are: a kind of tower crane bearing; structure is simple; easy to use; pass through cable protecting device; friction between cable and wire conduit is converted to the pivoting friction with deep groove ball bearing, reduces friction coefficient, effectively use cable to protect to tower crane; improve the service life of cable, and reduce the potential safety hazard of operation field.

Detailed description of the invention
Below in conjunction with accompanying drawing, specific embodiment of the utility model is elaborated.
As Figure 1-3, a kind of tower crane bearing, comprise undersetting 1, gear ring backing plate 2 and fender guard, described protection-gear comprises cable anti-cutting cover 4 and deep groove ball bearing 5, described undersetting 1 is box stand, on it, lower surface is respectively provided with a manhole, described two manhole centers of circle on the same line, described gear ring backing plate 2 is annular, outside the manhole being enclosed within described undersetting 1 upper surface, and fixed by bolt 3 with described undersetting 1 upper surface, the manhole of described undersetting 1 lower surface is provided with expanded metal lath 8, described expanded metal lath 8 lower surface is provided with wire guide plate 6, cable runs through described wire guide plate 6 and described expanded metal lath 8 successively by wire conduit 7, the open end that described wire conduit 7 passes described expanded metal lath 8 and described cable anti-cutting overlap 4 and to be throughly connected, described deep groove ball bearing 5 be fixed on be positioned at described wire conduit 7 open end inside.Cable is through the center of described deep groove ball bearing 5.
Described cable anti-cutting cover 4 is back taper.
Described expanded metal lath 8 is provided with open channel 9, and described open channel 9 is connected with climbing support.
Also reinforced rib is provided with between the described upper and lower surface of undersetting 1.
A kind of tower crane bearing, by arranging cable protecting device, namely cable anti-cutting cover 4 and deep groove ball bearing 5, make the friction of cable and wire conduit 7 change the pivoting friction of cable and described deep groove ball bearing 5 into, significantly reduce friction coefficient, reduce frictional influence.The cable anti-cutting that wire conduit 7 end connects simultaneously overlaps 4, and it is expand design to the periphery relative to wire conduit 7, and this changes wire conduit 7 and the friction Impact direction of cable, increases the area of contact of cable and workpiece.Therefore, cable when tower crane works and wire conduit 7 and cable anti-cutting overlap 4 the stressed change of friction, actv. extends the service life of cable, to a greater extent improve the safety factor caused because of cable failure.
Above an embodiment of the present utility model has been described in detail, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to the utility model application range change and improve, and all should still belong within patent covering scope of the present utility model.
