Description

Foreliggende oppfinnelse angår løpekatt for taubaner med wire ført via en endetrinse via løpekatten tilbake til vinsjen, idet trekkwiren henholdsvis returwiren er ført en gang rundt to respektive nokker, og den ene nokken er drivkoblet med en løfte/senke-anordning for last. The present invention relates to a running cat for cableways with a wire led via an end pulley via the cat back to the winch, the pull wire and the return wire being led once around two respective cams, and one cam is drive-coupled with a lifting/lowering device for loads.

Ved tidligere kjente anordninger med løpekatt har det vært nødvendig å låse løpekatten fast til en baerewire samtidig som løpehjulet brukes som kraftuttak for heving og senking av lasten. Denne konstruksjonen er unødvendig komplisert og kostbar. In previously known devices with a trolley, it has been necessary to lock the trolley to a carrier wire at the same time as the trolley is used as a power take-off for raising and lowering the load. This construction is unnecessarily complicated and expensive.

Foreliggende oppfinnelse har til formål å gjøre det mulig å fastholde løpekatten på et vilkårlig sted mens en løfter og senker en last uten at det er nødvendig å foreta en låsing til en baerewire. Samtidig løper wiren stram hele tiden. The purpose of the present invention is to make it possible to hold the trolley in an arbitrary place while lifting and lowering a load without it being necessary to lock to a carrier wire. At the same time, the wire runs taut all the time.

Videre er det et formål med foreliggende oppfinnelse å oppnå samme fordeler som ved bruk av en løpekatt for taubane med tre løpende liner eller to løpende og en fast bærekabel. Furthermore, it is an object of the present invention to achieve the same advantages as when using a trolley for a ropeway with three running lines or two running lines and a fixed carrying cable.

Ved tradisjonelt utstyr med to liner må banen slakkes ned for å kunne trekke ut heiselinene. In the case of traditional equipment with two lines, the track must be relaxed in order to be able to pull out the hoist lines.

Fra NO-PS 37316 og US-PS 2 601 228 er det kjent utstyr med en løpekatt hvor trekkwiren og returwiren er ført rundt hver sine nokker. Den ene nokken er drivkoblet med en heiseanord-ning. From NO-PS 37316 and US-PS 2 601 228 there is known equipment with a running cat in which the traction wire and the return wire are led around separate nocks. One cam is drive-connected with a lifting device.

Ifølge oppfinnelsen foreslås det en anordning av innlednings-vis nevnte art hvis karakteristiske trekk fremgår av krav 1. Ytterligere trekk ved oppfinnelsen fremgår av de øvrige uselvstendige kravene. According to the invention, a device of the type mentioned at the outset is proposed, the characteristic features of which appear in claim 1. Further features of the invention appear in the other independent claims.

Ved at oljemotorene er koblet sammen på hydraulikksiden vil disse styre hverandres hastighet. Dette medfører at lik mengde wire passerer begge nokkene samtidig. Da nokken på vinsj sidens inntrekksside er koblet til heisetrommelen via f.eks. kjededrift, kan heiselinen kjøres ut eller inn ved bare å bytte vinsjretning. As the oil motors are connected together on the hydraulic side, these will control each other's speed. This means that an equal amount of wire passes through both cams at the same time. As the cam on the winch's retracting side is connected to the hoist drum via e.g. chain drive, the hoist line can be run out or in by simply changing the direction of the winch.

Kjøringen av løpekatten langs banen foregår ved at en radiostyrt ventil mellom oljemotorene stenger oljestrømmen til begge løpene på oljemotoren, tilkoblet nokk/heise-linjetrommelen, og samtidig frikobler den andre motoren slik at denne kan løpe fritt. Driving the trolley along the track takes place by a radio-controlled valve between the oil motors shutting off the oil flow to both runners on the oil motor, connected to the cam/hoist line drum, and at the same time disconnecting the other motor so that it can run freely.

I det påfølgende skal oppfinnelsen beskrives nærmere med henvisning til tegningene, hvor: In what follows, the invention will be described in more detail with reference to the drawings, where:

Fig. 1 viser skjematisk løpekatten. Fig. 1 schematically shows the running cat.

Fig. 2 viser skjematisk koblingen mellom oljemotorene. Fig. 2 schematically shows the connection between the oil motors.

Fig. 1 viser skjematisk løpekatten for taubaner med trekkwiren 7 ført en gang rundt en nokk 1 med returwiren (6) ført over en nokk 2. Nokken 2 er vist koblet med en oljemotor 9 som via hydraulikkledninger 3 er koblet med en oljemotor 10 forbundet med nokken 1. Nokken 1 er vist koblet via et kjededrev 5 med en heisetrommel 4. Heisetrommelen kan imidlertid være forbundet på andre måter med nokken 1, som f.eks. via tannhjulsoverføring, henholdsvis kan heisetrommelen være direkte koblet med nokken 1. Ved forflytting av løpekatten langs linen vil nokken 1 være faststående, dvs. oljeforbindelsen mellom oljemotoren 10 og 9 via ledningen 3 er stengt og nokken 2 kunne løpe fritt slik at når det trekkes i henholdsvis wiren 7 eller 6 vil løpekatten beveges. Ved løfting av last henholdsvis senking av last ved hjelp av heisetrommelen 4 er oljemotorene 9 og 10 koblet sammen på hydraulikksiden, og disse vil styre hverandres hastighet slik at ved trekk i wirene 6 og 7 vil nokken 1 og 2 dreies i samme retning med lik hastighet, og løpekatten vil da stå rolig mens heisetrommelen 4 beveges for løfting henholdsvis senking av en last 8. Fig. 1 schematically shows the catenary for cableways with the traction wire 7 led once around a cam 1 with the return wire (6) led over a cam 2. Cam 2 is shown connected to an oil motor 9 which via hydraulic lines 3 is connected to an oil motor 10 connected to the cam 1. The cam 1 is shown connected via a chain drive 5 with a hoisting drum 4. The hoisting drum can, however, be connected in other ways to the cam 1, such as e.g. via gear transmission, respectively the hoisting drum can be directly connected with the cam 1. When moving the cat along the line, the cam 1 will be fixed, i.e. the oil connection between the oil motor 10 and 9 via the line 3 is closed and the cam 2 could run freely so that when it is pulled wire 7 or 6 respectively, the running cat will move. When lifting a load or lowering a load using the hoisting drum 4, the oil motors 9 and 10 are connected together on the hydraulic side, and these will control each other's speed so that when the wires 6 and 7 are pulled, the cams 1 and 2 will turn in the same direction at the same speed , and the trolley will then stand still while the hoist drum 4 is moved to lift or lower a load 8.

Ventilene mellom oljemotorene 9 og 10 kan stenges henholdsvis åpnes ved hjelp av en radiostyring. The valves between the oil motors 9 and 10 can be closed or opened using a radio control.

Koblingen av hydraulikken mellom oljemotorene 9 og 10 er skjematisk antydet på fig. 2, hvor den styrbare ventilen er antydet med henvisningen 13. Med henvisningen 11 er antydet en oljetank, og med henvisningen 12 er vist tilbakeslags-ventiler. The connection of the hydraulics between the oil motors 9 and 10 is schematically indicated in fig. 2, where the controllable valve is indicated by the reference 13. An oil tank is indicated by the reference 11, and non-return valves are shown by the reference 12.
