Description

Sikringsanordning ved linetrekkdrevne vogner for skråbaner. Safety device for cable traction-driven carriages for inclined tracks.

Foreliggende oppfinnelse angår en sikringsanordning ved linetrekkdrevne vogner for skråbaner. En sånn sikringsanordning består av en bremsemekanisme, som er forbundet med trekklinen på en slik måte at den står i uvirksom stilling så lenge det utøves trekk i linen, men som når trekket opphører, f. eks. ved linebrudd, automatisk føres til virksom stilling. The present invention relates to a safety device for cable traction-driven carriages for inclined tracks. Such a safety device consists of a braking mechanism, which is connected to the pulling line in such a way that it remains in an inactive position as long as the line is being pulled, but which when the pull ceases, e.g. in the event of a line break, automatically moved to active position.

I norsk patent nr. 79 203 er angitt en In Norwegian patent no. 79,203, a

slik sikringsanordning som i første rekke er karakterisert ved at vognens bæreplan er forbundet med trekklinen samt lagret forskyvbart på vognrammen véd skråfør-inger på en slik måte at det, så lenge det utøves trekk i linen, holdes forskjøvet til en i forhold til rammen løftet stilling, men som når nevnte trekk opphører automatisk vir føres i motsatt retning og senkes og herved forårsake en avbremsing av vognen. Foreliggende oppfinnelse angar en modifikasjon av en sikringsanordning such a safety device which is primarily characterized by the fact that the carriage's support plane is connected to the draw line and stored displaceably on the carriage frame via inclined guides in such a way that, as long as the line is being pulled, it is held offset to a position raised in relation to the frame , but which when said move ceases automatically will be guided in the opposite direction and lowered, thereby causing a deceleration of the carriage. The present invention relates to a modification of a safety device

ifølge norsk patent nr. 79 203. Istedetfor skråføringer utvirkes ifølge foreliggende oppfinnelse hevningen og senkningen av vognens bæreplan ved anvendelse av vinkelformete to-armete vektstenger som fra det på bæreplanet monterte omdreiningspunkt har et horisontaltgående ben, hvorpå vognens hjullagre er montert og et nærmest vertikaltgående ben som står i forbindelse med vognens trekkline. Videre består according to Norwegian patent no. 79 203. According to the present invention, instead of inclined guides, the raising and lowering of the carriage's support plane is effected by the use of angular two-armed weight rods which, from the pivot point mounted on the support plane, have a horizontally extending leg, on which the carriage's wheel bearings are mounted and an almost vertically extending leg which is connected to the trolley's draw line. Furthermore consists

For å klargjøre oppfinnelsen skal den To clarify the invention, it must

beskrives detaljert i forbindelse med ved-lagte tegninger. Figur 1 og .2 viser henholdsvis et side-og grunnriss av en vogn utstyrt med sik-ringsanordningen ifølge en utførelsesform for oppfinnelsen. Figur 3 viser bremseanordningen ifølge oppfinnelsen i åpen stilling. Figur 4 viser den samme i virksom stilling. is described in detail in connection with the attached drawings. Figures 1 and 2 respectively show a side and ground plan of a carriage equipped with the safety device according to an embodiment of the invention. Figure 3 shows the brake device according to the invention in the open position. Figure 4 shows the same in active position.

Ved den følgende henvisning til tallene på tegningene benyttes entallsform, men der skal forstås at hvert hjul på vognen er utstyr med en anordning ifølge oppfinnelsen. In the following reference to the numbers in the drawings, the singular form is used, but it should be understood that each wheel on the cart is equipped with a device according to the invention.

På figur 1 betegner 1 vognen med til-hørende hjul 2 med hjulaksler 3. Vognens trekkline festes til skiven 5 som er plant anordnet på midten av forbindelsesstangen 4. Denne stang er i endene festet til to langsgående koplingsstenger 6 som strekker seg bakover og ender i koplingsstykket 7, som ved hjelp av tappene 9 er dreibart forbundet med den øvre ende av det vertikale ben 8 på den vinkelformete, toarmete In Figure 1, 1 denotes the wagon with associated wheels 2 with wheel axles 3. The wagon's draw line is attached to the disk 5 which is arranged flat on the middle of the connecting rod 4. This rod is attached at the ends to two longitudinal connecting rods 6 which extend backwards and end in the connecting piece 7, which by means of the pins 9 is rotatably connected to the upper end of the vertical leg 8 of the angular two-armed

vektstang 8, 10,'. Denne vektstang er dreibart forbundet med bæreplanet ved tappen barbell 8, 10,'. This weight rod is rotatably connected to the bearing plane at the pin

10, mens det nevnte horisontale ben på vektstangen utgjøres av vognhjulets aksellager, som således kan betraktes som vekt-stangens omdreiningspunkt, idet tappen 10 (med bæreplanet) og tappen 9 faktisk vil svinge om' hjullagret. 10, while the aforementioned horizontal leg of the weight rod is made up of the carriage wheel's axle bearing, which can thus be regarded as the pivot point of the weight rod, as the pin 10 (with the bearing plane) and the pin 9 will actually swing around the wheel bearing.

Til koplingsstykkene 7 er dreibart festet to langsgående koplingsstenger 6,, som strekker seg bakover til det bakerste hjulsett på vognen og forøvrig står i forbindelse med et vektstangsarrangement identisk med det for det forreste hjulsett. Two longitudinal connecting rods 6 are rotatably attached to the coupling pieces 7, which extend backwards to the rear wheelset of the carriage and are otherwise connected to a lever arrangement identical to that for the front wheelset.

Claims

1. Modification of the safety device as specified in patent no. 79 203, characterized in that the raising and lowering of the carriage's support plane instead of by using

The division of inclined guides is effected by the use of angular weight rods (8-10') arranged one at each end of each wheel axle, which weight rods each have a leg (10') which extends approximately horizontally and carries an axle bearing, while the other leg

(8) extends vertically or at an angle upwards and at its upper end is rotatably connected to a connecting rod (6,) running in the longitudinal direction of the carriage, which is connected to the draw line, the carriage frame on which the support plane is fixed being mounted on pins (10) arranged on the weight bars at their top points behind the wheel axles.

2. Safety device as stated in claim 1, characterized in that the carriage frame or rail clamps are attached to the support plane, each comprising a clamp sleeve (13) attached to the underside of the support plane which expands downwards and is open at the bottom, as well as clamp jaws (16) stored in the clamp sleeve, the upper end of which is pivotally attached to a pin (15 ), which are displaceably stored in vertical grooves (14) in the walls of the klein sleeves and whose lower ends protrude from the clamping sleeve so that they can grip the rail (11) and are clamped to this when the support plane is lowered from the raised position so that the clamping sleeve forces the clamping jaws against the rail during swing about the pin (15).

3. Safety device as stated in claim 2, characterized in that the lower ends of the clamps (16) are made with inclined surfaces designed to rest against and slide on the rail foot during the clamping movement.

4. Safety device as stated in claims 2 and 3, characterized in that two pins (17) or the like are arranged at the lower end of the clamping sleeve (13) which serve to swing the clamping jaws apart when the support plane is lifted. Cited publications:
