Description

Predmetom vynálezu je zariadenie na uchytenie břemena, najmS podvalu železničného zvršku, ktoré sa m8že použit pri výměně podvalov a inej manipulécie s nimi.The object of the invention is a device for attaching a load, in particular a railway superstructure, which can be used in the replacement and other handling of the sleepers.

Doposial sa podvaly pri vymieňaní uchytávajú čelusťami, ktoré slúžia len na vyvodenie sily potrebnej na vysunutie, alebo vsunutie podvalu, nie sú schopné podval držať v požadovanej polohe, v dSsledku čoho nie je možné podval strojom na výměnu podvalov uchytit z miesta uloženia a premiestnit ho na iné vhodné miesto. Na premiestňovanie podvalov sa musia používat zdvíhacie prostriedky.So far, the sleepers have been interchanged with jaws which only serve to exert the force necessary to extend or insert the sleeper, are unable to hold the sleeper in the desired position, as a result of which the sleeper can not be fastened from the storage location and moved to another suitable place. Lifting equipment must be used to move the sleepers.

VySSie uvedené nedostatky sú odstránené zariadením na uchytenie břemena podlá vynálezu, ktoré má čeluste otočné voči skříni chápadla, naklépajúcej sa okolo čapu uchytenie, pričom pohyblivé čelusť je ovládaná priamočiarym hydromotorom, do ktoréhe sa privádza ovlédacie médium cez otočný prevédzač a na přívod média je napojený hydraulický akumulátor. čeluste sú opatřené antifrikčnou vrstvou a jedna z nich samostavitelne upevněné voči povrohu podvalu. Toto usporiadanie umožňuje dokonalé uchytenie podvalu, jeho premiestňovanie z dopravného prostriedku priamo do miesta uloženia pri vsúvanl a opačné pri vysúvaní vadného podvalu a počas přemiestňovania zaručuje požadovanú polohu podvalu, čo má zs následok zvýSenie tempa výměny podvalov.The above drawbacks are overcome by a load-holding device according to the invention having jaws pivotable relative to the gripper housing tilting around the pivot pin, the movable jaw being actuated by a linear hydraulic motor to which the viewing medium is fed via a rotary guide and connected to a fluid supply battery. the jaws are provided with an anti-friction layer and one of them is self-adjustingly fastened to the surface of the sleeper. This arrangement allows the sleeper to be perfectly gripped, moved from the vehicle directly to the stowed position when inserted and vice versa when the defective sleeper is pulled out and guarantees the desired sleeper position during relocation, resulting in increased sleeper replacement rate.

Příklad uaporiadania zariadenia na uchytenie podvalov podlá vynálezu je schématicky znázorněný na priloženom obrázku v řeze rovinou predchédzajúcou osou symetrie chápadla.An example of an arrangement of a sleeper fastening device according to the invention is shown schematically in the attached figure in cross section through a plane preceding the axis of symmetry of the gripper.

Zariadenie je upevněné na výškovo přestavitelnom ramene χ výložníka stroja na výměnu podvalov pomooou čapov 2, okolo ktorých sa mfiže naklápať pomocou priamočiareho h.ydromotora χ, ktorého oko piestnice je spojené čapom 4. s ramenom skrine 6 chápadla.The device is mounted on the height-adjustable boom arm χ of the sleeper replacement machine by means of pins 2 around which it can be tilted by means of a linear motor χ, whose piston rod eye is connected by a pin 4 to the arm of the gripper housing 6.

V skrini 6 je otočné uložená nosná rúra 2 na ložiskách 8. Otáčanie rúry 2 lubovolným smerom sa deje skrutkovým kolesom £, ktoré je spojené s rúrou 2 pomocou pera 10. Skrutkové koleso £ je v zábere so skrutkou 11, ktorá je poháňaná rotačným hydromotorom 12. Poloha rúry 2 7 sniere svojej osi je zaistené deleným krúžkom 13 a poistným prstencom 11·The support tube 2 is rotatably mounted in the housing 6 on the bearings 8. The rotation of the tube 2 in any direction is effected by a screw wheel 6 which is connected to the pipe 2 by means of a tongue 10. The screw wheel 6 engages a screw 11 which is The position of the pipe 2 7 of its axis is secured by a split ring 13 and a retaining ring 11 ·

Pracovně kvapalina sa privádza do priamočiareho hydromotora 15. ktorý ovládá pohyblivú čelusť 16 chápadla prívodmi 17 cez rotačný prevádzač 18. K přívodu 17 praoovnej kvapaliny do hydromotora 15 pri uchytení podvalu 2 Je napojený hydraulický akumulátor 27. ktorý zabezpečuje stály přítlak pohyblivej čeluste i po ukončení dodávky kvapaliny do hydromotora 15. Hydromotor 15 je na jednej straně upevněný čapom 19 a na druhej straně je čapom 20 spojený s pohyblivou čelusťou 16 chápadla. K rúre 2 Je 7 tvare strmeňa upevněná pevná čelusť 21 chápadla, v ktorej sa naohádza přítlačné doska 22. Na konci pevnej čeluste 21 chápadla je na čapě 23 upevněný jazyk 24. ktorý sa m8že vyklepiť pri zasúvaní pevnej čeluste 21 chápadla pod podval 2 tlakom Strku do čiarkovanej polohy až po spodnú plochu podvalu a takto ho očísluje od Strku před jeho uchytením.Operatively liquid is supplied to the linear hydraulic motor 15 which controls the movable jaw 16 of the gripper 17 through the inlets 18 to the rotary transducer 17 praoovnej supply of liquid to the hydraulic motor 15 is fitted into the sleeper 2 I t is connected to a hydraulic accumulator 27, which ensures a constant contact pressure of the movable jaw and the end The hydraulic motor 15 is fixed on one side by a pin 19 and on the other side by a pin 20 connected to the movable jaw 16 of the gripper. The tube 2 and 7 J-shaped yoke, a stationary gripper jaw 21, which naohádza pressure plate 22. At the end of the fixed jaw 21 of the gripper 23 is mounted on the pin 24, which is a language m8že knocked out during the insertion of the fixed jaw 21 of the gripper clip tie 2 pressure The shot into the dashed position up to the bottom of the sleeper and thus numbering it from the shot before it is attached.

Uchytenie podvalu 2 sa uskutoční pohybom pohyblivej čeluste 16 chápadla, ktoré sa otéča okolo čapu 25 a zovretím podvalu 2 aamostavitelnou doakou 26, uloženou v pohyblivej čelusti 16 chápadla na valcovej ploché.The fastening of the sleeper 2 is effected by moving the movable jaw 16 of the gripper, which rotates around the pin 25 and grips the sleeper 2 with an adjustable dock 26 mounted in the movable jaw 16 of the gripper on a cylindrical flat.

Přítlačné došky 22 a 26 sú vyměnitelné. Ich dotykové plochy s podvalom sú opatřenéThe pressure plates 22 and 26 are replaceable. Their contact surfaces with sleeper are provided

198 511 vhodným antifrikčným materiálom. Po uchopení podvalu pohybom zariadenia vo vyznačenou! smere sa podval vysúve, alebo vsúva.198 511 suitable antifriction material. After grasping the sleeper by moving the device in the marked! the direction of the sleeper extends or retracts.
