Abstract
The utility model relates to a concave sheet type friction buffer used for smoothly stopping an object which is out of control. A concave sheet type movable friction sheet, a fixed friction sheet, a concave surface block and a convex surface block are assembled on a shaft supported by two support saddles, wherein steel cylinders on which steel ropes are wound are respectively assembled on the movable friction sheet and on a movable block. The object which is out of control impacts the steel ropes to drive the steel cylinders to rotate, and then, the steel cylinders drive the movable friction sheet to rotate; consequently, friction is generated between the movable friction sheet and the fixed friction sheet to generate larger friction force. Therefore, the utility model performs an excellent buffer function and the object can be smoothly stopped.
Description
The utility model step and a kind of energy disperser that can produce friction force.
At present the friction-type energy disperser is used for the buffering of overrunning of colliery lifting means more, overruns even during disconnected rope pier jar, lifting means is steadily stopped when promoting pulleying or transferring, and is unlikely to violent bump and has an accident a buffer action.The friction buffer relevant with the application is the patent No. 9524077.9 " multi-disc type friction-type energy disperser ".Its structure is, is equipped with somely decide alternately to be equipped with slightly larger in diameter in the movable friction plate of deciding friction lining between friction lining and sheet and the sheet on the axle of two bearings, is equipped with the therewith cylinder of rotation of lay winding wire ropes on the movable friction plate.When the object strikes steel rope of hypervelocity, cylinder rotates to make between fixed, the movable friction plate friction force takes place, and the object of motion steadily stops.The deficiency of this friction buffer is, because friction lining is the plane, its frictional area is fixing limited, and its friction buffer power equals positive pressure and multiply by the gross area that friction coefficient multiply by friction face again.Friction force is less under the identical friction lining number situation identical with overall dimensions (diameter), and buffer action is insufficient.
The application's purpose is to after the above-mentioned technological improvement, improves friction force and then gives full play to bigger buffer action.
The application's scheme is: 1, alternately be equipped with the recessed chip movable friction plate that some recessed chips that do not turn mutually with axle are decided friction lining and can be swayed on the axle of two seat supports; 2, also be respectively fitted with concave surface piece and the convex surface piece that produces friction force with friction lining mutually in the both sides of axle.Be that outermost is when deciding friction lining, concave surface piece or convex surface piece are the motion blocks that can sway; Movable friction plate concave surface piece or convex surface piece when outermost be with axle rotatable mutually decide piece; 3, on movable friction plate, overlap the steel cylinder that is wound with steel rope that plays rotation with last one.
In such scheme, axle two ends outermost can be that movable friction plate also can be to decide friction lining, can an end be that moving plate one end is a stator also, so the concave surface piece and the convex surface piece at axle two ends are according to above-mentioned different situations, can be that motion block also can be to decide piece.When being motion block, put the steel cylinder co-rotation with movable friction plate.
Its good effect is, under the same situation of diameter with the print number, the frictional area of spill friction lining increases, it is relevant with the concave surface angle to increase multiple, and the concave surface angle is littler, and concave surface is long-pending bigger, its friction force is just bigger, therefore good buffer effect is under the situation of original profile diameter size, obviously effective than prior art.Below in conjunction with embodiment of description of drawings.
Fig. 1, Fig. 2 are the front view (analysing and observe) and the left views of general assembly drawing;
Fig. 3, Fig. 4 are the front view (analysing and observe) and the left views of movable friction plate;
Fig. 5, Fig. 6 are front view (analysing and observe) and the left views of deciding friction lining.Omit right elevation among the above-mentioned figure.
Marginal data: 1-steel cylinder; The 2-right support abutment; 3-concave surface piece; 4-convex surface piece; The 5-movable friction plate; 6-decides friction lining; The 7-castellated shaft; The 8-left support abutment; The 9-belleville spring; The 10-pressing plate; The 11-nut; 12-steel wire fly
From Fig. 3-Fig. 6, find out movable friction plate 5 and to decide friction lining 6 be that the concave surface angle is the recessed sheet about α=60 °; Wherein the neighboring of movable friction plate 5 has the male splines that cooperates with steel cylinder 1, and the inner periphery sideband of deciding friction lining 6 has the female splines that cooperates with castellated shaft 7; The concrete mounting structure of Fig. 1 is, castellated shaft 7 is supported on right support abutment 2 and the left support abutment 8, axle is with the convex surface piece 4, the movable friction plate 5 that cooperate with 7 spline on 7 successively, decides friction lining 6 and concave surface piece 3 between two bearings, moving plate and stator be assembling alternately, assembling slice is several to be decided according to particular case, thereby forms a plurality of spill friction faces.Show ten friction faces among the figure.Right-hand member at right support abutment 2 inner shafts 7 has shoulder in addition, puts butterfly spring 9 and pressing plate 10 on the left support abutment outer shaft 7 again, and tightens with nut 11; The steel cylinder inwall also has spline, is enclosed within during assembling on the movable friction plate 5 that cooperates with its spline.During use, steel rope 12, one ends are fixed on the energy disperser body in the winding, and the other end consolidates in suitable place according to the specific requirement of using the scene or the steel rope two ends respectively are separately fixed on two energy disperser bodies.
Its principle of work is, when thing out of control impacts steel rope, and the rotation of steel rope pulling steel cylinder, steel cylinder drives moving plate 5 simultaneously and rotates together, with stator 6 concave surface pieces 3 that do not rotate and convex surface piece 4 generation relative friction forces, reaches the purpose of buffering.
