Abstract

The utility model relates to a reversing wire winch which is used for the coal separating plant. In the utility model, the end part of the existing winch is provided with a clutch, the passive slice 2 of the clutch is fixed with the end face of a roller 1, and the end face of the roller 1 is provided with a taper hole A which is used to position a steel ball 3. An active piece 11 is connected with a main shaft 7 through a key 8, and the main shaft 7 is provided with an axial hole which is used to arrange the steel ball 3, a pressure spring 4 and a top pillar 5. A plate 6 which is used to regulate the centrifugal force is connected with the main shaft 7 through screws. The end part of the wire cable of the reversing wire winch is connected with the end part of the wire cable of the traction winch together. When the traction winch pushes the wire cable, the reversing wire winch pulls the wire cable. The utility model has the advantages of simple structure, and convenient operation. Besides, the utility model is not only suitable for the coal separating plant, but also for the mine and the lumbering field.

Description

Reversing wire winches

The utility model is the end face fit on power-transfer clutch at the cylinder of existing winch, is applicable to mine, coal preparation plant and traction compartment, harvesting of wood field.

Need after duff that coal preparation plant selects or the gangue entrucking by pulling out in the factory, the traction of wait railway locomotive is transported, and transports the empty wagons railway carriage or compartment to vacate the place, continues entrucking; At present, the coal preparation plant of home and abroad all transports factory with the compartment that winch will be filled duff or gangue; Transport, at first traction winch is put rope at every turn, moves steel rope to as ready compartment place by manpower simultaneously, promptly returns rope; And is hung on steel rope on the compartment, for the traction winch traction is prepared; Each rope that returns needs seven people to spend half an hour.It is the manual labor of the heaviness of a not only time-consuming but also effort.

The utility model has designed the rope winch a kind of time, with the traction winch logotype, returns the rope that returns that rope has replaced present manpower La Fiber mode with machinery.

The utility model is to install power-transfer clutch at an end of winch drum, recalls the rope winch; Its steel cord ends and traction winch steel cord ends connect together; Because the rotating speed of traction winch is certain, rope speed changes with its radius size apart from the winch drum axis, and steel rope can not contact with ground when restricting in order to return, and the minimum velocity of returning the rope winch need be greater than the maximum speed of traction winch; Return on the rope winch end face power-transfer clutch is housed, the strength of adjusting clutch transmits is to guarantee that steel rope can not rupture; The power-transfer clutch that returns the rope winch is by rotating plate 11, formed by moving plate 2, steel ball 3, pressure spring 4, fore-set 5 and plate 6; Be fixed together by the end face of moving plate 2, be shaped on taper hole A on it for steel ball location and transfer torque with winch drum 1; Rotating plate 11 is connected with main shaft 7 by key 8, is shaped on the axial hole that steel ball 3, pressure spring 4 and fore-set 5 are installed on it; The plate 6 of regulating power-transfer clutch strength size is by being threadedly connected on the main shaft 7 size of scalable clutch transmission torque when rotor plate 6.

The power-transfer clutch accent power assembly that is made of steel ball 3, pressure spring 4 and fore-set 5 is 4～24.

Advantage of the present utility model, returning the rope winch is to install power-transfer clutch at the end face of the cylinder that has winch now, the moment of transmission can be regulated, and is simple in structure, easy to use, improved workman's labor condition.

Description of drawings:

Fig. 1 is back the rope winch,

Fig. 2 is back rope winch work scheme drawing,

Accompanying drawings the utility model embodiment: the drum spindle 8 that will move through back rope winch 18 through belt transmission (electrical motor is 4.5 kilowatts, 735 rev/mins), drop-gear box 13, coupler 12 by electrical motor 15 is seen Fig. 1 through the cylinder 1(that power-transfer clutch drives back the rope winch again); Steel rope (diameter phi 12.5) end that returns the rope winch is connected with traction winch steel rope (diameter phi 24.5) end; Steel rope kiss the earth when returning rope, the minimum rope speed that returns the rope winch is 11.23 meters/minute; The maximum speed of traction winch is 10.5 meters/minute; When returning the work of rope winch (Volume rope), traction winch is put rope; Owing to return rope winch speed greater than traction winch speed, steel rope is subjected to open (drawing) power, so steel rope can not relax or sagging kiss the earth, has avoided mechanical damage; When the tension force (pulling force) that bears when steel rope was excessive, when promptly tension force surpassed back rope winch clutch setting, the steel ball 3 of power-transfer clutch was pushed away taper hole A; It is led, is skidded by moving plate 11,2; Cylinder does not change; When tension force reduced, the steel ball 3 of power-transfer clutch entered taper hole A again, returned the rope winch and worked on.Be operated in the strength scope of setting so return the rope winch cable, steel rope can not broken, and has guaranteed safety.Coupler is equipped with two dowels for 12 li; dowel middle part diameter is thinner; it is to consider what suitable safety factor was set according to the maximum allowable Zhi And that returns the rope winch cable; the rope winch clutch is malfunctioning when returning; when its strength surpasses above-mentioned setting value; to cut off dowel, make the left alone without help commentaries on classics of cylinder, and promptly return rope winch second protection and work.When returning the work of rope winch, when steel rope rope sling 17 arrives compartment 19,, rope sling 17 is hung on the compartment 19 the left alone without help car of two winches.Return the rope end-of-job.Start traction winch, draw the compartment on the one hand, also drive back the rope winch simultaneously and put rope,, drive whole transmission device and rotate because of not self-locking of retarder.

The end face that returns rope winch drum 1 is equipped with the power-transfer clutch (see figure 1), being fixed on by moving plate on the end face of cylinder 1 of power-transfer clutch is shaped on 12 taper hole A by moving plate 2 end face upper edge circumference are equidistant, for easily manufactured, make the small cylindrical opening coaxial earlier, can process taper hole accurately with taper hole A; Guarantee to contact with the good of steel ball 3; The rotating plate 11 of power-transfer clutch is contained on the main shaft 7, by key 8 transfer torques, power-transfer clutch axially by nut 9 locking, be shaped on the rotating plate 11 12 with by the corresponding axial hole of taper hole A on the moving plate 2, steel ball 3, pressure spring 4 and fore-set 5 are installed; Plate 6 is contained on the main shaft 7 by screw thread; 12 power-transfer clutch strength of transferring the power assembly to constitute that swivel mount 6 scalable are made up of steel ball 3, pressure spring 4 and fore-set 5.Stable in order to guarantee the power-transfer clutch setting, adopts 11 fore-sets 5 and a step pin axle 10, after power-transfer clutch is set up, the microcephaly of step pin axle is inserted among the hole B of plate 6, prevent the commentaries on classics of plate 6 screw threads pine.When adjusting power-transfer clutch, earlier step pin axle 10 is ejected in the B of hole.Return simple, the easy to operate work of restricting of returning that has replaced " manpower La Fiber " mode with machinery of rope winch structure.
