Abstract
The utility model relates to a double-rotation preventing sleeve which prevents steel wires from wringing and twisting. The double-rotation preventing sleeve includes two sets of rotating shafts and rotary nuts; the rotary nuts can be rotatably sleeved on the rotating shafts; the two sets of rotating shafts and rotary nuts are respectively and reversely assembled at the two ends of a barrel; and the rotary nuts are connected with the end part of the barrel by threads. The double-rotation preventing sleeve is provided with two sets of rotating shafts and rotary nuts; if one set is damaged, the other set can still run, which greatly improves the reliability. The double-rotation preventing sleeve separates the stators of the current single-rotation preventing sleeve into two parts which include the rotating shafts and the barrel, thus being very simple and convenient to replace and overhaul parts.
Description
Technical field
The utility model relates to the annex that is used for the elevator machinery suspender, relates in particular to a kind of two commentaries on classics that prevents that steel rope is hinged, twines and prevents pivoted housing.
Background technology
Anti-pivoted housing is usually used on some hoisting device of harbour, harbour, power plant, especially be usually used in the suspension hook assembly, main purpose is to discharge the moment of torsion that steel rope in use produces, thereby hinged, the winding that prevent steel rope are avoided steel rope and are ruptured because of the increase of moment of torsion, and can play the effect of counterweight.When being used in combination, to guarantee to change faster the safety performance and the commercial efficiency of speed, the best with the quick shackle of C shape, high strength shackle etc.
Anti-pivoted housing connection mode commonly used has: 1, anti-pivoted housing+shackle+steel rope; 2, socket+shackle+anti-pivoted housing+steel rope (perhaps elevator chain); 3, socket+shackle+anti-pivoted housing; 4, pyriform rope sling+quick shackle of the C shape+anti-pivoted housing+quick shackle of C shape+pyriform rope sling; 5, rope rig+high strength shackle+anti-pivoted housing+high strength shackle+socket.
Anti-rotation is enclosed within and has wearing and tearing during pyriform rope sling, shackle etc. are connected, and flies upward and rugged environment such as moist coastal uses down through the Iron Ore Powder of being everlasting, coal dust again, it is required just very high.
A kind of anti-pivoted housing of the prior art, as shown in Figure 1, it mainly comprises parts such as stator 1, circular nut 2, thrust ball bearing 3, the nut 4 of turning, deep groove ball bearing 5, rotating shaft 6.Should anti-pivoted housing be a kind of single anti-pivoted housing that changes, bearing 3,5 be in case occur downright badly, and it does not just have this effect that has, and just can't discharge and can cause steel rope to be twisted off thereby steel rope reverses the power that is produced, and causes unnecessary loss, poor reliability; And when in use, personnel can't go to check, maintenance inconvenience.
Summary of the invention
The utility model provides a kind of two anti-pivoted housing that changes at the problems referred to above, and this anti-pivoted housing can two-wayly rotate, the reliability height, and maintenance is convenient.
According to the technical solution of the utility model: a kind of two anti-pivoted housings that change, comprise rotating shaft and the nut of turning, the described nut of turning is sleeved in the described rotating shaft rotationally, described rotating shaft and the described nut of turning have two covers, oppositely be assemblied in the two ends of cylindrical shell respectively, the described nut thread of turning is connected the end of described cylindrical shell.
Described cylindrical shell is fixed on the described nut of turning by holding screw.Described turning is equipped with radial bearing between nut and the described rotating shaft.Be equipped with thrust baring between described cylindrical shell and the described rotating shaft, an end of described thrust baring is resisted against on the described nut of turning, and its other end is compressed by the circular nut that is threaded in described rotating shaft the inner.The junction of described circular nut and described rotating shaft is provided with stop screw.Described cylindrical shell is provided with the lubricating cup that communicates with described thrust baring.Be embedded with steel bushing in the through hole of described rotating shaft outer end.
Technique effect of the present utility model is: 1, the utility model is provided with the two cover rotating shaft and the nuts of turning, if a damage, running can also be continued in the other end, and reliability improves widely.2, the utility model is split into rotating shaft and cylindrical shell two parts with single divided stator that changes anti-pivoted housing of the prior art, and it is very easy to change the maintenance part.3, be embedded with steel bushing in the through hole of rotating shaft, after steel bushing may wear to a certain degree, a needs is changed a new steel bushing and just can be continued to use, and was simple in structure, prolonged the service life of anti-pivoted housing, also saved resource.
Description of drawings
Fig. 1 is the structural representation of a kind of anti-pivoted housing of the prior art;
Fig. 2 is a structural representation of the present utility model;
Fig. 3 is the structural representation of the another kind of embodiment of the rotating shaft in the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is further described.
As shown in Figure 2, the utility model is a kind of two anti-pivoted housing that changes, and is to improve to form on as shown in Figure 1 single changes the basis of anti-pivoted housing.It comprises rotating shaft 11 and the nut 13 of turning, and the nut 13 of turning is sleeved in the rotating shaft 11 rotationally.Characteristics of the present utility model are: the rotating shaft 11 and the nut 13 of turning have two covers, oppositely are assemblied in the two ends of cylindrical shell 15 respectively, and the nut 13 of turning is threaded in the end of cylindrical shell 15.After adopting this structure, reliability of the present utility model improves widely, and the anti-pivoted housing of two commentaries on classics becomes single anti-pivoted housing use of changeing if a damage also has the other end continuation to operate at least, how has been equivalent to layer insurance, and safety performance improves greatly.In addition, the utility model is equivalent to the single stator 1 that changes anti-pivoted housing among Fig. 1 is separated into rotating shaft 11 and cylindrical shell 15 two parts, and it is very easy to change the maintenance part.
Nut 13 is loosening in order to prevent to turn, and cylindrical shell 15 is fixed on the nut 13 of turning by holding screw 19.
Be equipped with radial bearing 12 between nut 13 and the rotating shaft 11 turning.Be equipped with thrust baring 3 between cylindrical shell 15 and the rotating shaft 11, an end of thrust baring 3 is resisted against on the nut 13 of turning, and its other end is compressed by the circular nut 16 that is threaded in rotating shaft 11 the inners.Radial bearing 12 is used to bear radial weight, and thrust baring 3 is used to bear axial load.Radial bearing 12 can adopt ball-bearing casing with thrust baring 3, also can adopt coro bearng.
Circular nut 16 is provided with stop screw 17 with the junction of rotating shaft 11, prevents that circular nut 16 from getting loose from the inner of rotating shaft 11.
