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

Za zmanjšanje pritiska na vrv, to je posebno pomembno pri vrvi iz polietilenski in drugih vlaken, je po izumu pogonska naprava za odvijanje vrvi na gozdarskem vitlu rešena s pogonom vrvenice in pogonom najmanj enega potisnega koluta. Vlek vrvi izvajajo vrteča gnana vrvenica in vrteči gnani potisni koluti. Motnjo zaradi nepredvidenih potegov vrvi pogonska naprava za odvijanje vrvi na gozdarskem vitlu po izumu prepreči, da ostaja napeta vrv med bobnom in pogonsko napravo za odvijanje vrvi na gozdarskem vitlu.In order to reduce the pressure on the rope, which is particularly important for ropes made of polyethylene and other fibers, according to the invention, the rope drive device on the forestry winch is solved by rope drive and drive of at least one thrust reel. The rope pull is performed by a rotating driven rope and rotating driven thrust reels. According to the invention, the disturbance due to unforeseen pulling of the rope by the drive rope unwinding device on the forestry winch prevents the tensioned rope between the drum and the rope driving device on the forestry winch.

Izum bo opisan na izvedbenem primeru in sliki, ki prikazujeThe invention will be described in the embodiment and in the drawing
