Abstract

The aim of the invention is to provide the concept of a driving device for unwinding the rope on a forestry winch from the drum, with a rope, located between the rotating rope pulley and at least one rotating driving disk in such a way that the torque of the driving engine (17) under a freely-rotating rope pulley (8) drives the driving disks (12, 13) via a drive (19, 20).

Description

Pogonska naprava za odvijanje vrvi na gozdarskem vitluDrive rope unwinding device on a forestry winch

Predmet izuma je pogonska naprava za odvijanje vrvi, ki bo vlekla vrv z bobna gozdarskega vitla in zmanjšala napor vlečenja vrvi, ki jo gozdarski delavec opravlja od vitla do hlodovine. Odvijanje vrvi pogonske naprave mora biti usklajen s hitrostjo hoje gozdarskega delavca. Ne sme delovati sunkovito, da prepreči nenamerno sprostitev vrvi v področju bobna in zgornje vrvenice gozdarskega vitla v vseh fazah procesa delovanja gozdarskega vitla.The subject of the invention is a propulsion device for unwinding a rope that will pull the rope from the drum of the forestry winch and reduce the effort of pulling the rope that the forestry worker performs from the winch to the log. The unwinding of the drive gear rope must be coordinated with the walking speed of the forestry worker. It must not act in a jerk manner to prevent the rope from being accidentally released in the area of the winch and the top rope of the forestry winch at all stages of the operation of the forestry winch.

Podobna rešitev je opisana v DE 202005020694, ki obravnava gozdarski vitel z bobnom na katerem je navita vrv, ki poteka z bobna preko zgornje vrvenice in naprej do hlodovine.A similar solution is described in DE 202005020694, which deals with a forestry winch with a drum on which a rope extending from the drum across the top rope and forward to the log is wound.

Na vrv na zgornji vrvenici potiska najmanj en kolut, vrvenica je gnana neposredno s hidravličnim motorjem. Pritisk koluta ustvariti silo trenja med vrvjo ter kontaktno površino vrvenice, da vrteča gnana zgornja vrvenica vleče vrv z bobna.At least one reel is thrust onto the top rope, the rope is driven directly by a hydraulic motor. Press the reel to create a friction force between the rope and the contact surface of the rope so that the rotating driven upper rope pulls the rope from the drum.

Pritisk na vrv deformira vrv oziroma slabo vpliva na strukturo pletenih žic vrvi in zmanjšuje njeno življenjsko dobo.The pressure on the rope deforms the rope or badly affects the structure of the braided wire ropes and reduces its life span.

Po izumu je pogonska naprava za odvijanje vrvi gozdarskega vitla rešena s pogonom najmanj dveh potisnih kolutov. Vlek vrvi izvajajo vrteči gnani potisni koluti. Motnjo zaradi nepredvidenih potegov vrvi pogonska naprava za odvijanje vrvi na gozdarskem vitlu po izumu prepreči in ostaja napeta vrv med bobnom in pogonsko napravo za odvijanje vrvi na gozdarskem vitlu.According to the invention, the drive device for unrolling the rope of the forest winch is solved by the drive of at least two thrust reels. The rope is driven by rotary driven thrust reels. According to the invention, the propulsion device for unwinding the rope on the winch according to the invention prevents the interruption due to unforeseen pulling of the rope and the tension rope between the drum and the rope unrolling drive on the forest winch remains.

Verižnika 22 in 23 v vertikalni ravnini povezuje veriga 21 in tvorijo pogon 19.In the casing 7, a pivot 8 is mounted pivotally on the axis of the casing 10. The casing 16 is pivotally mounted on the casing 16 in the casing 16. a reel 12 and a chain 22 adjacent thereto, and a pusher disk 13 and a chain sprocket 23 fixed on the thrust roller shaft 18 and a chain 21 connecting them in a vertical plane to form a drive 19.

K tej ravnini vzporedno potekajo v vertikalni ravnini vrvenica 8 in potisna kolut 12 in 13 ter so v stalnem kontaktu s vrvjo 4.To this plane, in a vertical plane, rope 8 and thrust reel 12 and 13 extend in continuous contact with rope 4.

Ohišje vrvenice 7 in ohišje potisnih kolutov 11 je sklenjeno s napenjalnim vijakom z vzmetjo 15 na poznan način.The housing of the rope 7 and the housing of the thrust reels 11 are locked in a known manner by a tensioning bolt with a spring 15.

V tem izvedbenem primeru je pogonski motor 17 nameščen ali na gred potisnega koluta 14 ali na gred potisnega kolutal8.In this embodiment, the drive motor 17 is mounted either on the thrust shaft 14 or on the thrust shaft8.

Pogon 20 tvorijo z verigo 25 povezani verižnik 24 vrtljivo nameščen na osi vrvenice 10, verižnik 22 fiksno nameščen na gredi potisnega koluta 14 ter verižnik 23 fiksno nameščen na gredi potisnega koluta 18.Figure 4 shows the rope puller - a drive motor solution on the rope axis. The actuator 20 is formed by a chain 25 connected by a chain 24 rotatably mounted on the axis of the line 10, a chain 22 fixedly mounted on the thrust shaft 14 and a chain 23 fixedly mounted on the thrust shaft 18.

V tem izvedbenem primeru je pogonski motor 17 nameščen na verižnik 24, ki je na osi vrvenice 10, in na ohišje vrvenice 7.In this embodiment, the drive motor 17 is mounted on the sprocket 24, which is on the axis of the rope 10, and on the housing of the rope 7.

V izvedbenih primerih lahko verigo zamenja ustrezen jermen verižnike pa jermenice.In embodiments, the chain may be replaced by a suitable pulley and pulleys.

Pogonski motorje lahko elektromotor priključen na električno energijo traktorja ali hidravlični motor v hidravličnem tokokrogu gozdarskega vitla. Zagon in zaustavitev delovanja pogonskega motorja mora biti skladna s krmilnim sistemom delovanja gozdarskega vitla.Propulsion motors can be an electric motor connected to the tractor's electrical energy or a hydraulic motor in the hydraulic circuit of the forestry winch. The starting and stopping of the drive motor must be in accordance with the control system of the winch winch.

Pogonski motor vrtilni moment prenaša na izbrano gred potisnega koluta ali na verižnik 24. Pogon 19, 20 vrtilni moment prenese na potisna koluta 12 in 13. S primemo silo potisnega koluta 12 in 13, ki ga ustvari napenjalni vijak z vzmetjo 15, je ustvarjena sila trenja med vrvjo 4 ter med kontaktno površino potisnega koluta 12 in 13 in med vrvjo in prosto vrtečo vrvenico 8 , da vrteča potisna koluta 12 in 13 vlečeta vrv z bobna 3. Hitrost vleka prilagodimo hitrosti hoje gozdarskega delavca, kije odvisna od terena.The drive motor transmits the torque to the selected thrust shaft or to the sprocket 24. A drive 19, 20 transfers the torque to the thrust wheels 12 and 13. By applying the force of the thrust wheel 12 and 13 created by the tensioning bolt with a spring 15, a force is created. friction between the rope 4 and between the contact surface of the thrust reel 12 and 13 and between the rope and the free rotating rope 8 so that the rotating thrust reels 12 and 13 pull the rope from the drum 3. The speed of the tow is adapted to the walking speed of the forest worker, which depends on the terrain.
