Abstract

The invention belongs to the field of forest winches, more precisely, to the filed of devices for winding and unwinding of a wire rope and enabling a reliable stoppage. The essence of the device for controlled winding and unwinding of a wire rope/a spun wire cable via a pulley is in that a sensor for monitoring the position of an end-piece/ending or adjustable stop/washer of the pulling end of the wire rope enables the switch-off of the winch in the case when the pulling end of the wire rope approaches a rope guiding mouth for a certain distance. The spatial or three-dimensional adaptation of the rope wire travel over the pulley and the sheave into the mouth and the end-piece is controlled by a swinging carrier of guiding/compression sheaves which are pressed by two springs adjustable by means of two bolts of the swinging carrier. Beside a hydraulic motor, the hydraulic drive features a damper valve and a non-return valve placed on a return flow pipe of the hydraulic motor.

Description

Naprava za kontrolirano navijanje in odvijanje žične vrvi-pleteniceControl for winding and unwinding of wire rope-braid

Področje tehnikeThe field of technology

Izum sodi v področje gozdarskih vitlov, bolj natančno v področje naprav za navijanje ali odvijanje žične vrvi in omogočanje zanesljivega ustavljanja.The invention belongs to the field of forestry winches, more specifically to the field of devices for winding or unwinding wire rope and allowing reliable stopping.

Tehnični problemA technical problem

Tehnični problem je konstrukcijska rešitev naprave za odvijanje žične vrvi-pletenice gozdarskega vitla, ki bo omogočala kontrolirano, enakomerno in prednapeto navijanje vrvi kot tudi možnost avtomatske prekinitve pogona žične vrvi, če je senzor preblizu končnika za vpetje hloda.A technical problem is the design solution of the rope-rope wire rope unwinding device, which will allow a controlled, even and prestressed winding of the rope, as well as the possibility of automatic interruption of the wire rope drive if the sensor is too close to the log clamp.

Znano stanje tehnikeThe prior art

Poznana je rešitev, kjer je vodilno-potisno kolo nameščeno na ročico, ki je lahko prednapeto s tlačno vzmetjo. Ta rešitev ima lahko eno, dve ali več ročic z vodilnopotisnimi kolesi. Bistvena slabost omenjene rešitve je nesorazmerno povečanje potisne sile v primeru odmika vodilnega kolesa zaradi spremenljivega prereza pletenice. Posledica tega je povečano trenje med pletenico, potisnim kolesom in vrvenico škripca. Pri tem se pletenica mehansko preoblikuje, oziroma se nekoliko spremeni prerez, ki vodi v prekomerno utrujanje pletenice in s tem bistveno krajše življenjske dobe pletenice. Po izumu je spreminjanje potisne sile vodilnih koles na pletenico zaradi pritrditve vodilnih koles na nihajni nosilec koles praktično zanemarljivo.There is a known solution where the guide-thrust wheel is mounted on a lever which can be prestressed by a pressure spring. This solution can have one, two, or more levers with guide wheels. A major disadvantage of this solution is the disproportionate increase in the thrust force in the event of a misalignment of the guide wheel due to the variable cross section of the braid. This results in increased friction between the braid, the thrust wheel and the pulley string. In this case, the braid is mechanically transformed, or slightly modified, which leads to excessive fatigue of the braid and thus significantly shorter life of the braid. According to the invention, changing the driving force of the guide wheels to the braid is practically negligible due to the attachment of the guide wheels to the swinging wheel carrier.

Prav tako znane rešitve ne nudijo prostorskega prilagajanja vodilnih koles in pletenice med navijanjem in odvijanjem pletenice z bobna vitla. Z dušilnim elementom s proti povratnim ventilom na povratnem vodu motorja hidravlične črpalke se doseže kontrolirano vrtenje vrvenice škripca pri navijanju in odvijanju vrvi. Proti povratni ventil omogoča nemoten pretok olja skozi hidravlični motor med navijanjem pletenice, kjer deluje hidravlični motor kot hidravlična črpalka. Pri znani rešitvi je funkcija nadzora obratovanja hidravličnega motorja opravljena z dodatnim razvodnim ventilom, ki hkrati nadzira aktivnost akumulatorja v hidravličnem sistemu. Slabost tega je začasno prekinjena funkcija hidravličnega akumulatorja in dodatni razvodni ventil.Also known solutions do not offer spatial adjustment of the guide wheels and braid during winding and unrolling of the winch braid. The throttle element with anti-return valves on the return line of the hydraulic pump motor achieves a controlled rotation of the pulley rope as the rope is wound and unwound. The non-return valve allows the oil to flow smoothly through the hydraulic motor while winding the braid, where the hydraulic motor acts as a hydraulic pump. In the known solution, the control function of the hydraulic motor is performed with an additional distribution valve, which simultaneously controls the activity of the battery in the hydraulic system. The downside of this is the suspended battery function and the additional manifold valve.

Opis rešitveDescription of the solution

Bistvo naprave za kontrolirano navijanje in odvijanje žične vrvi-pletenice preko škripca je v tem, da tipalo za nadzor položaja končnika-zaključka ali nastavljivega omejevala-podložke vlečnega konca pletenice omogoča izklop vitla v primeru, če se vlečni konec pletenice s končnikom približa na določeno razdaljo k vodilnem ustju pletenice. Prostorsko oziroma tridimenzionalno prilagoditev žične vrvi, ki potuje preko škripca in vrvenice v ustje in končnik, uravnava nihajni nosilec vodilnih-potisnih koles, ki ju pritiskata dve vzmeti na vijakoma nihajnega nosilca. Hidravlični pogon ima poleg hidravličnega motorja, dušilni ventil in proti povratni ventil na povratnem vodu hidravličnega motorja.The crux of the device for controlled winding and unwinding of a wire rope-braid via a pulley is that the sensor for controlling the position of the end-end or adjustable stop-washer of the pulling end of the braid allows the winch to be switched off if the pulling end of the braid with the end approaches a certain distance to the guide mouth of the braid. The spatial or three-dimensional adjustment of the wire rope, which travels over the pulley and the cord into the mouth and the end, is governed by the swing arm of the guide-thrust wheels, which are pressed by two springs on the screws of the swing arm. In addition to the hydraulic motor, the hydraulic drive has a throttle valve and a non-return valve on the return line of the hydraulic motor.

Naprava za kontrolirano navijanje in odvijanje žične vrvi-pletenice po izumu bo v nadaljevanju podrobneje opisan s pomočjo slik, ki kažejo:The device for controlled winding and unwinding of the wire rope-braid according to the invention will now be described in further detail by means of the figures showing:

Naprava za kontrolirano, enakomerno in prednapeto navijanje in odvijanje žične vrvi je konstruirana tako, da je žična vrv 3 iz škripca 1 napeljana skozi sklop 2 v vodilno ustje 19, na katerem je nameščeno tipalo 4. Žična vrv 3 je iz ustja 19 speljana v končnik 5 za vpetje tovora. Med končnikom 5 in ustjem 19 je nameščen nastavljiv omejevalnik 18 gibanja žične vrvi 3. Pletena žična vrv 3 je iz škripca 1 skozi polkrožni utor 13a vrvenice 13 in polkrožnima utoroma koles 7 in 8 vodena skozi ustje 19. Kolesi 7 in 8 sta nameščeni na nihajnem nosilcu 6 in sta vpeta s vijakoma 9 in 10, ki sta vzmetena s parom vzmeti 11 in 12. Kolo 7, ki je po obliki enako kolesu 8, je oblikovano tako, da je v srednjem delu kolesa 7, kjer je prečnik največji, polkrožni utor za žično vrv 3. Od polkrožnega utora kolesa 7 ali kolesa 8 se prečnik koles zmanjšuje do ojačitve za os koles. Oblika kolesa 7 ali 8 spominja na debelejši disk, ki ima vbočen polkrožni utor po sredini. Vrvenica 13 je oblikovana tako, da je v sredini utor 13a med dvema krožnima stranicama, ki sta na zunanji strani ravni, na notranji pa se ožita proti dnu utora 13a. Ko hidravlični motor poganja žično vrv 3 po utoru 13a vrvenice 13, je le-ta na zgornji strani pritisnjena v utora kolesa 7 in kolesa 8, ki zaradi vzmeti 11 in 12 enakomerno pritiskata žično vrv 3 v utor 13a vrvenice. Ker je pritisk koles 7 in 8 na vrv 3 in utor 13a vrvenice 13 reguliran z vzmetmi 11 in 12 pritrjenih z vijakoma 9 in 10 na nihajni nosilec 6, je zagotovljen siguren in stabilen položaj vrvi 3 pri obratovanju škripca. To zagotavlja tridimenzionalno prilagajanje vrvenice 13, koles 7 in 8 položaju vrvi 3 v utoru 13a.A device for controlled, even and prestressed winding and unwinding of a wire rope is constructed such that the wire rope 3 from the pulley 1 is guided through the assembly 2 into the guide mouth 19 on which the sensor 4 is mounted. The wire rope 3 is guided from the mouth 19 to the end. 5 to secure the load. An adjustable wire rope movement limiter 18 is mounted between the end piece 5 and the mouth 19. The braided wire rope 3 is guided from the pulley 1 through a semi-circular groove 13a of the rope 13 and the semi-circular grooves of the wheels 7 and 8 through the mouth 19. The wheels 7 and 8 are mounted on a swinging brackets 6 and are fixed with screws 9 and 10, which are suspended by a pair of springs 11 and 12. The wheel 7, which is identical in shape to the wheel 8, is shaped such that in the middle part of the wheel 7, where the diameter is the largest, semicircular wire rope groove 3. From the semicircular groove of wheel 7 or wheel 8, the wheel diameter is reduced to the reinforcement for the wheel axis. The shape of the wheel 7 or 8 is reminiscent of a thicker disc having a convex semicircular groove in the middle. The row 13 is formed in such a way that in the center there is a groove 13a between the two circular sides, which are on the outside of the level, and on the inside, they are narrowed towards the bottom of the groove 13a. When the hydraulic motor drives the wire rope 3 through the groove 13a of the rope 13, it is pressed on the upper side into the grooves of the wheel 7 and the wheels 8, which, due to the springs 11 and 12, press the wire rope 3 evenly into the groove 13a of the rope. As the pressure of the wheels 7 and 8 on the rope 3 and the groove 13a of the rope 13 is regulated by springs 11 and 12 secured by screws 9 and 10 to the swing arm 6, a secure and stable position of the rope 3 is ensured during the pulley operation. This provides a three-dimensional adjustment of rope 13, wheels 7 and 8 to the position of rope 3 in groove 13a.

Tipalo 4 vrši nadzor položaja končnika 8 ali nastavljivega omejevalnika 18 vlečnega konca žične vrvi 3. Prednapet nihajni nosilec 6 potisne vodilni kolesi 7 in 8 na žično vrv 3 in vrvenico 13 škripca 1. Hidravlični motor 14 poganja vrvenico 13 in ker je med žično vrvjo 3, vodilnima kolesoma 7 in 8 ter vrvenico 13 tlak, nastalo trenje omogoča nemoteno kontrolirano, enakomerno in prednapeto navijanje in odvijanje žične vrvi 3. Nihajni nosilec 6 omogoča nemoteno prilagajanje vodilnih koles 7 in 8 na žično vrv 3 in skoraj konstanten pritisk vodilnih koles 7 in 8 na žično vrv 3. Povratni vod 17 hidravličnega motorja 14 je opremljen z dušilnim ventilom 15 in povratnim ventilomThe sensor 4 controls the position of the end 8 or the adjustable limiter 18 of the towing end of the wire rope 3. The prestressing swing arm 6 pushes the guide wheels 7 and 8 onto the wire rope 3 and the pulley 13. 1. The hydraulic motor 14 drives the rope 13 and because it is between the wire rope 3 , the guide wheels 7 and 8 and the pulley 13 pressure, the resulting friction allows for a smoothly controlled, even and prestressed winding and unwinding of the wire rope 3. The swinging carrier 6 allows for the smooth adjustment of the guide wheels 7 and 8 to the wire rope 3 and the almost constant pressure of the guide wheels 7 and 8 to wire rope 3. The return line 17 of the hydraulic motor 14 is equipped with a throttle valve 15 and a check valve

16. V primeru odvijanja žične vrvi 3 dušilni ventil 15 in proti povratni ventili 16 kontrolirata gibanje žične vrvi 3 tako, da se nastavi hitrost gibanja žične vrvi 3 z nastavitvijo dušilnega ventila 15.16. In the case of unwinding of wire rope 3, the throttle valve 15 and the non-return valves 16 control the movement of the wire rope 3 by adjusting the speed of movement of the wire rope 3 by adjusting the throttle valve 15.

Na sliki 1 je prikazan škripec 1 s sklopom 2 za kontrolirano navijanje in odvijanje žične vrvi 3. Tipalo 4 nadzira položaj končnika 5 skupaj z omejevalnikom 18, ki je nastavljiv vzdolž vrvi 3 in z nastavljeno točko za izvršitev izklopa pogona žične vrvi. V primeru dotika končnika 5 in tipala 4, omejevalnik 18 sproži izklop tokokroga oziroma pogona 14 za navijanje žične vrvi vitla in s tem prekine vlek pletene žične vrvi 3. Na ta način ne pride do poškodbe vitla, škripca ali celo roke, v kolikor delavec ni pozoren in drži za žično vrv.Figure 1 shows a pulley 1 with assembly 2 for controlled winding and unwinding of the wire rope 3. The sensor 4 controls the position of the terminal 5 together with the stop 18, which is adjustable along the rope 3 and with a set point for executing the trip of the wire rope drive. In the case of contacting the end piece 5 and the sensor 4, the restraint 18 triggers the disconnection of the winch wire rope 14 or actuator 14, thereby interrupting the pull of the braided wire rope 3. In this way, the winch, pulley or even the hand is not damaged unless the worker is pay close attention to the wire rope.

Z napravo za kontrolirano navijanje in odvijanje žične vrvi-pletenice po izumu je omogočena varnostna funkcija samodejnega izklopa vleka vitla in kontrolirano, tridimenzionalno zagotavljanje pravilne lege in posledično enakomerno porazdeljene vlečne sile v žični vrvi, ki se enakomerno navija na boben vitla. Slika 2 prikazuje prerez nihajnega nosilca 6 vodilnih koles 7 in 8, kjer je prednapetost vzmeti 11 in 12 nastavljena s pomočjo vijakov 9 in 10. Po izumu nihajni nosilec 6 vodilnih koles 7 in 8 zagotavlja skoraj konstantno potisno silo le-teh na žično vrv 3 in omogoča tridimenzionalno prilagajanje vodilnih koles glede na žično vrv 3 in vrvenico škripcaThe device for controlled winding and unwinding of the wire rope-braid according to the invention enables the safety function of automatic shut-off of the winch winch and the controlled, three-dimensional provision of correct position and consequently evenly distributed pulling force in the wire rope, which is evenly supported on the winch drum. Figure 2 shows a cross-sectional view of the swing arm 6 of the guide wheels 7 and 8, where the pre-tension of the springs 11 and 12 is adjusted by screws 9 and 10. According to the invention, the swing arm 6 of the guide wheels 7 and 8 provides an almost constant thrust of these on the wire rope 3 and allows three-dimensional adjusting of the guide wheels with respect to wire rope 3 and pulley string
