Abstract
The utility model discloses a turn round the rope device, especially a turn round rope device that is used for swing arm formula tower machine to become a width of cloth rope system. The utility model provides a release torsional stress prevents that wire rope from beating a turn round rope device that is used for swing arm formula tower machine to become a width of cloth rope system who twists, including casing, deep groove ball bearing, thrust ball bearing, connecting axle and nut, being provided with mounting structure on the outer wall of casing, being provided with bearing installation space in the casing, the casing bottom is provided with intercommunication bearing installation space's shaft hole, deep groove ball bearing and thrust ball bearing install in bearing installation space, and deep groove ball bearing coaxial arrangement is on thrust ball bearing, the connecting axle is fixed through the nut after passing shaft hole, thrust ball bearing, deep groove ball bearing in proper order. Owing to adopted deep groove ball bearing and thrust ball bearing simultaneously, this makes the rotation that the connecting axle can be free to can also bear great tensile stress, wire rope torsional stress is above that connected in the release that the rotation of connecting axle can be little.
Description
Technical field
The utility model relates to one and turns round rope device, especially a kind ofly turns round rope device for movable arm type tower machine variable amplitude rope system.
Background technology
For whip-typed tower crane, in the city of building dense, there is very large advantage.But the multiplying power of variable amplitude rope system is large, rope is grown up, and steel rope is wound around on reel, during turnover assembly pulley, all can produce tersional stress, and the steel wire rope entering or go out assembly pulley is long larger, and accumulative tersional stress is larger.
Therefore need to set up at variable amplitude rope end to turn round rope device, to discharge tersional stress, prevent wire rope twisting, improve the service life of steel rope.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of release tersional stress, and what prevent wire rope twisting turns round rope device for movable arm type tower machine variable amplitude rope system.
What the utility model solved that its technical matters adopts turns round rope device for movable arm type tower machine variable amplitude rope system, comprises housing, deep groove ball bearing, thrust ball bearing, adapter shaft and nut;
The outer wall of described housing is provided with mounting structure, is provided with bearing installing space in described housing, housing bottom is provided with the axis hole being communicated with bearing installing space;
Described deep groove ball bearing and thrust ball bearing are arranged in bearing installing space, and described deep groove ball bearing is coaxially arranged on thrust ball bearing;
Described adapter shaft is fixed by nut through after axis hole, thrust ball bearing, deep groove ball bearing successively.
Further, also comprise cover of dust, the top of described housing is provided with placement mouth, and described cover of dust sealing is arranged on places on mouth.
Further, also comprise seal ring, described seal ring sealing is arranged between thrust ball bearing and housing bottom.
Further, lower gasket is provided with between described thrust ball bearing and deep groove ball bearing.
Further, upper gasket is provided with between described nut and deep groove ball bearing.
Further, also comprise spring cotter, described nut is hexagon slotted nut, and the top of described adapter shaft is provided with pin-and-hole, and described spring cotter is through pin-and-hole and hexagon slotted nut.
The beneficial effects of the utility model are: owing to have employed deep groove ball bearing and thrust ball bearing simultaneously, this makes adapter shaft be free to rotate, and larger tensile stress can be born, the rotation of adapter shaft can be little release connection steel rope tersional stress thereon, prevent wire rope twisting, improve the service life of steel rope.Housing can actv. impact protection, avoids inner bearing to sustain damage.
Accompanying drawing explanation
Fig. 1 is exploded perspective view of the present utility model;
Fig. 2 is the schematic diagram after the utility model is installed;
Parts, position and numbering in figure: cover of dust 1, nut 2, upper gasket 3, deep groove ball bearing 4, lower gasket 5, thrust ball bearing 6, seal ring 7, housing 8, spring cotter 9, adapter shaft 10.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, the utility model comprises housing 8, deep groove ball bearing 4, thrust ball bearing 6, adapter shaft 10 and nut 2;
The outer wall of described housing 8 is provided with mounting structure, in described housing 8, is provided with bearing installing space, bottom housing 8, be provided with the axis hole being communicated with bearing installing space;
Described deep groove ball bearing 4 and thrust ball bearing 6 are arranged in bearing installing space, and described deep groove ball bearing 4 is coaxially arranged on thrust ball bearing 6;
Described adapter shaft 10 is fixed by nut 2 through after axis hole, thrust ball bearing 6, deep groove ball bearing 4 successively.One end of adapter shaft 10 is thread end, and one end is provided with steel rope coupling end.When assembling, thrust ball bearing 6, deep groove ball bearing 4 being arranged in the bearing installing space in housing 8, then adapter shaft 10 being fixed by nut 2 through after axis hole, thrust ball bearing 6, deep groove ball bearing 4 successively.After having assembled, adapter shaft 10 can rotate freely.Then rope device will originally be turned round be installed to the end of variable amplitude rope system, concrete erection plan as shown in Figure 2, originally turning round rope device is installed on bearing by the mounting structure on housing 8 outer wall, mounting structure is generally axle, the two ends displacement of clamp restriction housing two ends vertical direction, bottom pin connects a cover of wedge, and cover of wedge is for installing steel rope, and whole device is quick and easy for installation.
Originally turning round structure that the thrust ball bearing 6 of rope device and deep groove ball bearing 4 form, to have rotational resistance little, can bear the feature of larger tensile stress.Be highly suitable on whip-typed tower crane.
In order to avoid dust enters in housing 8, as shown in Figure 1, also comprise cover of dust 1, the top of described housing 8 is provided with placement mouth, and described cover of dust 1 sealing is arranged on places on mouth.Also comprise seal ring 7, between described seal ring 7 sealing is arranged on bottom thrust ball bearing 6 and housing 8.Lower gasket 5 is provided with between described thrust ball bearing 6 and deep groove ball bearing 4.Upper gasket 3 is provided with between described nut 2 and deep groove ball bearing 4.Also comprise spring cotter 9, described nut 2 is hexagon slotted nut, and the top of described adapter shaft 10 is provided with pin-and-hole, and described spring cotter 9 is through pin-and-hole and hexagon slotted nut.
