Definitions

  • the present invention belongs to the field of forestry winches, more precisely to the field of constructional details of forestry winches, which are related to winding of a rope onto a drum.
  • the present invention relates to an electro-hydraulic winder for winding a wire rope and a winch with said winder.
  • the technical problem which is solved by the present invention, is construction of a system that will enable even winding of the wire or the pulling rope on the drum.
  • Mechanical assemblies that track the winding action and ensure approximately even winding are known, however, also these assemblies face deviations, as during tilting of the winch the weight of the winder affects the quality of rope winding.
  • the disadvantage of mechanical winders are large dimensions consequently leading to challenging installation or reduced compactness of the construction.
  • Patent US2662703 describes an automatic mechanism for leading rope during winding, said mechanism comprising mechanical components.
  • This solution differs from the present invention in its design.
  • Patent US2424380 discloses a winch with a guide or a rope winder, wherein the guide is slidably installed on a drive shaft, so as to allow rotation of the drum during rope winding, while the guide travels back and forth in parallel to the drum, thus guiding the rope which is being wound on the drum.
  • This solution prevents entanglement of the rope and prevents clustering of the rope (several layers of rope on one end of the drum, while the other parts of the drum have no or few rope layers).
  • a disadvantage of this solution is that it is not resistant to side loads.
  • the invention differs from the solution described in US2424380 in the mechanical components.
  • Document CN101700859 describes a winch with an automatic rope winder, winch comprises a steel wire rope pulley, a rope releaser sliding block and a winch roller which are sequentially connected by a steel wire rope.
  • the steel wire rope pulley is placed on a disc rope releaser through a positioning shaft; the rope releaser sliding block is arranged on parallel slideways which are parallel vertically, and a rope release jack and a rope release positioning block are sequentially connected and arranged at one end of the rope releaser sliding block; the rope release jack is communicated with an electric hydraulic pump.
  • This winder differs from the present invention in its construction.
  • a winder for uniform winding of a wire rope onto a drum said winder comprising a mechanical assembly of the winder and an electrohydraulic assembly.
  • the mechanical assembly is directly connected to the drum, onto which wire rope is wound, and comprises a cross spindle with a nut and a drive assembly for translation of torque from the drum to the cross spindle.
  • Left and right movement of the nut imitates the path and speed of movement of the wire rope during winding on the drum.
  • a rotational angle sensor is attached to the nut, wherein the sensor is connected to a controller of the winch and measures deviation of the winder with regards to the nut.
  • the controller corrects the pathway of the winder based on the measured deviations (angles) in order to harmonize movement of the nut and a holder for cylinders and consequently the wire rope.
  • the present invention does not have the mechanical assembly, thus having a simpler construction.
  • the essence of the electric-hydraulic winder for uniform winding of the wire rope onto a drum of a winch is in that the winder comprises:
  • the drum has attached rings with suitably distributed grooves, preferably evenly (uniformly) or unevenly distributed grooves along the circumference. Alternatively, grooves may be made, cut or milled, directly in the side of the drum. These grooves are counted with the inductive sensor, which is preferably mounted on the housing of the winch in a fixed manner.
  • the controller can calculate the rotation speed of the drum and consequently the speed of movement of the wire rope left and/or right with regards to the pipe of the drum (on which the wire rope is wound). Thus, the controller knows the current position of the wire rope on the drum.
  • the direction of drum rotation is known to the controller on the basis of signal caused by the user selecting either activation of pulling or opening of the brake.
  • the preferred option for movement of the holder with redirecting cylinders is the hydraulic cylinder, as winches are usually equipped with a hydraulic system and because forces for movement are large. However, it is also possible to achieve movement with a linear electromotor, but this solution is expensive. In addition, a strong electricity source is needed and further optimization of the winder and winch construction would be necessary.
  • the preferred embodiment of the winder with the angle sensor and forks on the holder of redirecting cylinders can also be replaced with a linear measuring rod or any other element that is suitable to measure or detect the position of the holder with redirecting cylinders.
  • a suitable crankshaft mechanism could be used, said crankshaft mechanism being arranged to move the rope as it is wound along the width of the drum.
  • the controller is arranged to sense:
  • the winch with the winder according to the invention may be any suitable winch, provided with one or two drums, wherein the winder enables optimal winding of the rope in even layers, thus significantly decreasing the possibility of rope damage.
  • the winder is mounted on the winch in any known manner from the side where the wire rope exits or runs towards the drum.
  • Figure 1 shows a drum B provided with rings B1 with evenly distributed grooves B2 along the circumference of the drum or the grooves are made directly on the side of the drum. Said grooves are counted by the inductive sensor 2, which is preferably mounted on the housing of the winch in a fixed manner.
  • Figure 2 depicts the winder for uniform winding of the wire rope onto the drum according to a possible embodiment for a double-drum winch, said winder comprising:
  • the holder 5 with redirecting cylinders 5a has transverse redirecting cylinders 5a for leading the wire rope as shown in figure 2 .
  • FIG. 3 A schematic view of control of the winder according to the invention is shown in figure 3 , wherein the controller based on the calculated position of the wire rope on the drum (tracking data from both sensors) opens the electrohydraulic valve and tracks the angle with the angle sensor 1a.
  • the hydraulic oil causes movement of the cylinder of the winder 5c and thus movement of repositioning cylinders 5 into a suitable direction and with a suitable speed, until the angle sensor reaches a neutral position.
  • a minimum angle of the rope running between the cylinders 5a on the holder with redirecting cylinders 5 and the rope on the drum is thus achieved, which consequently leads to proper winding of the wire rope onto the drum.
