Abstract
The utility model discloses a kind of tower crane arm head anti-twisting equipment, comprise and draw ear, fixing anti-ly turn round pedestal and slewing arrangement, the described ear that draws comprises otic placode and upper axle, and otic placode has one and can, through the hole of bearing pin, draw the upper axle of ear to be provided with a captive nut through the anti-end turning round pedestal.Described slewing arrangement is a bearing set, along direction laid out in parallel two bearings drawing axle on ear in described bearing set.The beneficial effects of the utility model are: draw ear to be integrated with the function of ear plate base and bolt, and otic placode to be monaural plate not yielding, adopt the bearing set be made up of two bearings, one for bearing axial force, one for bearing side force, so not only can bear and drawn the pulling force of ear but also can freely rotate, and certain side force can have been born, thus not fragile.
Description
Technical field
The utility model relates to a kind of anti-twisting equipment, particularly relates to a kind of tower crane arm head anti-twisting equipment.
Background technology
Anti-twisting equipment is the necessary component of tower crane.When tower machine uses ordinary steel rope, steel rope can produce very large torsion, at this moment need the torsion on steel rope to discharge.During torsion release, steel rope can rotate a few even tens circles.Anti-twisting equipment is exactly a kind of a kind of device discharging steel wire rope torsion, and its one end connects with steel rope, and one end can freely be rotated by bearing, and when steel rope producing torsion, steel rope just can be rotated freely by this device and discharge torsion.General steel cord ends can be connected with anti-twisting equipment by wire clips or cover of wedge.
Summary of the invention
For above-mentioned existing issue, the utility model provides a kind of tower crane arm head anti-twisting equipment, and sound construction is not fragile.
To achieve these goals, the technical solution adopted in the utility model is: a kind of tower crane arm head anti-twisting equipment, comprise and draw ear, fixing anti-ly turn round pedestal and slewing arrangement, the described ear that draws comprises otic placode and upper axle, otic placode has one and can, through the hole of bearing pin, draw the upper axle of ear to be provided with a captive nut through the anti-end turning round pedestal.
Described slewing arrangement is a bearing set, along direction laid out in parallel two bearings drawing axle on ear in described bearing set.
Bearing pin is equipped with in the described hole of the end of ear of drawing.
Described bearing set is thrust baring and radial bearing, is also provided with spacer between thrust baring and radial bearing.
Back-up ring is also equipped with in the outside of described bearing set.
The beneficial effect that the utility model plays is: draw ear to be integrated with the function of ear plate base and bolt, and otic placode to be monaural plate not yielding, adopt the bearing set be made up of thrust baring and radial bearing, one for bearing axial force, one for bearing side force, so not only can bear and drawn the pulling force of ear but also can freely rotate, and certain side force can have been born, thus not fragile.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the constructional drawing drawing ear.
Fig. 3 is the birds-eye view of Fig. 2.
In figure: 1, otic placode, 2, bearing set, 3, upper axle, 4, anti-ly turn round pedestal, 5, captive nut, 6, bearing pin, 7, spacer, 8, back-up ring, 21, thrust baring, 22, radial bearing.
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 and draws ear, fixing anti-ly turns round pedestal 4 and slewing arrangement, the described ear that draws comprises otic placode 1 and upper axle 3, and otic placode 1 has one and can, through the hole of bearing pin 6, draw the upper axle 3 of ear to be provided with a captive nut 5 through the anti-end turning round pedestal 4.
Described slewing arrangement is a bearing set 2, along direction laid out in parallel two bearings drawing axle 3 on ear in described bearing set 2.
Bearing pin 6 is equipped with in the hole of the end of described otic placode 1.
Described bearing set 2 is thrust baring 21 and radial bearing 22, is also provided with spacer 7 between thrust baring and radial bearing.
Back-up ring 8 is also equipped with in the outside of described bearing set 2.
Function of drawing ear to be integrated with ear plate base and bolt of the present utility model, and otic placode to be monaural plate not yielding, adopt the bearing set be made up of two bearings, one for bearing axial force, one for bearing side force, so not only can bear and drawn the pulling force of ear but also can freely rotate, and certain side force can have been born, thus not fragile.
