Description

Izum se odnosi na jedan uređaj za polaganje pragova kolosijeka s najmanje jednom portalnom dizalicom s uzdužnim nosačem, pomičnom dužinom kopirnih tračnica, uređajem za držanje pragova, koji bočno naliježu na oba kraja pragova, a prilagodiv je po visini, i jednim u stražnjem dijelu uređaja, na uzdužnom nosaču postavljenim uređajem za odlaganje pragova. The invention relates to a device for laying track sleepers with at least one gantry crane with a longitudinal support, a movable length of copying rails, a device for holding the sleepers, which lie laterally on both ends of the sleepers, and is adjustable in height, and one in the rear part of the device, on a longitudinal support with a device for placing sleepers.

Takav jedan uređaj je od prije poznat iz spisa DE-AS 1 117 627. Kod njega su međusobno povezane dvije portalne dizalice koje imaju jedan zajednički središnji uzdužni nosač, koji se pruža u uzdužnom smjeru kolosijeka. Ovaj je povezan s uređajem za držanje pragova, izvedenim od po visini prilagodivih kolotura, koji za nalijeganje na krajeve pragova ima L oblikovane tračnice. Kod svakog kraja središnjeg uzdužnog nosača postavljen je jedan, u uzdužnom smjeru istog pomičan, od kolotura izveden uređaj za odlaganje pragova, opremljen jednim nosivim kutnikom koji naliježe na donju stranu praga. Ovaj poznati uređaj za polaganje pragova ima malu efikasnost, pogotovo stoga što odlaganje pragova zahtijeva relativno visoko postavljanje i ne omogućava točno postavljanje pragova s konstantnim razmakom između pragova. Such a device is already known from the file DE-AS 1 117 627. In it, two gantry cranes are interconnected and have a common central longitudinal support, which extends in the longitudinal direction of the track. This is connected to a device for holding thresholds, made of height-adjustable pulleys, which has L-shaped rails to rest on the ends of the thresholds. At each end of the central longitudinal support, there is one device, movable in the longitudinal direction, made of pulleys, for placing sleepers, equipped with one load-bearing angle that rests on the lower side of the sleeper. This known device for placing thresholds has low efficiency, especially since the placement of thresholds requires relatively high placement and does not allow accurate placement of thresholds with a constant distance between thresholds.

Iz AT-PS 258 337 poznat je jedan jači uređaj za uklanjanje i odlaganje kolosijeka koji se sastoji od tračnica i pragova. Ovaj se uređaj sastoji od dvije portalne dizalice koje se mogu pomicati po kopirnim tračnicama, koje su pomoću U oblikovanih transportnih traka povezane s nosivim valjcima okomitim na njihovu uzdužnu os. Ove se transportne trake oslanjaju na, pomoću hidraulički pokretanog uređaja po visini prilagodive konzole. Na taj se način mogu transportne trake prilagoditi svakoj utovarnoj ravnini zbog predaje dopremljenih pragova. Na jednom uzdužnom kraju uređaja postavljene su okomite vodilice, koje imaju visinski prilagodive kukaste hvatače za zahvaćanje donje strane pragova koji leže na tucaničkom zastoru i trebaju se ukloniti. Ovim hvatačem podignuti pragovi se sakupljaju u dvije međusobno paralelne ravnine na spomenutim transportnim putanjama i odvode na jedan vagon za odlaganje pragova. Ovaj poznati uređaj ipak nije namijenjen za polaganje pragova. From AT-PS 258 337, a stronger device for removing and depositing tracks consisting of rails and sleepers is known. This device consists of two gantry cranes that can be moved along copying rails, which are connected by means of U-shaped conveyor belts to bearing rollers perpendicular to their longitudinal axis. These conveyor belts rest on, by means of a hydraulically actuated device, a height-adjustable console. In this way, the conveyor belts can be adapted to each loading plane due to the delivery of the delivered thresholds. At one longitudinal end of the device, vertical guides are placed, which have height-adjustable hook grippers for gripping the underside of the thresholds that lie on the tucanic curtain and need to be removed. The sleepers lifted by this catcher are collected in two mutually parallel planes on the aforementioned transport paths and taken to one wagon for the disposal of the sleepers. However, this well-known device is not intended for laying thresholds.

Konačno, iz DE-AS 1 203 811 poznat je uređaj za polaganje pragova, pomičan po kopirnim tračnicama, s jednom vodoravnom transportnom trakom za uskladištavanje pragova koji se polažu. Na tu se transportnu traku nadovezuju, u poprečnom smjeru međusobno razdvojeni, transporteri s valjcima, koji se mogu okretati oko jedne osi koja se pruža u uzdužnom smjeru kolosijeka, odnosno uređaja. Prag koji sa sabirne transportne trake prebaci transportere s trakama, zahvaća se s obje čelne strane okretnim zahvatnim mehanizmom, poslije čega se s donje strane praga postavljen transporter s valjcima uklanja. To, međutim, ima nedostatak da će se zahvatnim uređajem zahvaćeni prag, zbog prostora koji je potreban za zakretanje transportera s valjcima, postaviti relativno visoko iznad razine tucaničkog zastora i slobodno će padati s relativno velike visine. Osim toga je postavljanje na transportnu traku pragova koji se nalaze na vagonu za pretovar pragova komplicirano. Finally, from DE-AS 1 203 811 a device for laying thresholds is known, movable on copying rails, with one horizontal conveyor belt for storing the thresholds to be laid. Conveyors with rollers are connected to this conveyor belt, separated from each other in the transverse direction, which can rotate around one axis that extends in the longitudinal direction of the track, that is, the device. The threshold that transfers the belt conveyors from the collecting conveyor belt is gripped on both front sides by a rotating gripping mechanism, after which the roller conveyor placed on the lower side of the threshold is removed. This, however, has the disadvantage that the threshold affected by the gripping device, due to the space required to rotate the conveyor with rollers, will be placed relatively high above the level of the tucanic curtain and will fall freely from a relatively high height. In addition, the installation of sleepers on a wagon for transshipment of sleepers is complicated.

Zadatak je prikazanog izuma ostvariti uređaj opisane vrste za polaganje pragova kolosijeka, kojim bi se moglo vršiti poboljšano preuzimanje i odlaganje pragova. The task of the presented invention is to realize a device of the described type for laying track sleepers, which could be used to carry out improved pickup and placement of sleepers.

Ovaj je zadatak, prema izumu, riješen tako, što je predviđen jedan vučni uređaj za pragove, izveden da nalegne na jednu uzdužnu stranu jednog praga koji se nalazi na uređaju za držanje pragova, koji je pomoću jednog pogonskog uređaja uzdužno pomičan cijelom dužinom uređaja za držanje u smjeru na sa stražnje strane postavljenom uređaju za odlaganje pragova. Kombiniranjem u uzdužnom smjeru pomičnog vučnog uređaja za pragove s jednim na kraju postavljenim uređajem za odlaganje pragova postiže se posebno efikasno odlaganje pragova pri kontinuiranom kretanju uređaja za polaganje pragova. Pri tome se na posebno prikladan način može izvesti, paralelno za zahvaćanje i odlaganje prvom, na uređaju za zahvaćanje pragova postavljenom pragu, uzdužno pomicanje pragova zadržanih na uređaju za držanje pragova, a pomoću vučnog uređaja. Na taj način leži prvi po redu da bude za držanje pragova, a pomoću vučnog uređaja. Na taj način leži prvi po redu da bude zahvaćen i položen prag uvijek u istom položaju, tako da je, na primjer, putanja pomicanja uređaja za zahvaćanje pragova za izvođenje polaganja pragova uvijek konstantna, i što je moguće kraća. Druga posebna prednost uređaja za polaganja pragova prema ovom izumu je to, što se nakon polaganja posljednjeg praga može izvršiti izuzetno brzo dopremanje slijedećeg sloja pragova, pri čemu se portalne dizalice kreću iznad postojećeg vagona za pretovar pragova, a uzdužni nosač se ujedno s uređajem za držanje pragova spušta za preuzimanje najgornjeg sloja pragova. U daljnjem razvoju izuma, uređaj za vuču pragova izveden je s najmanje jednim povlakačem, predviđenim za nalijeganje na jednu uzdužnu stranu pragova postavljenim na uređaju za držanje pragova, koji je povezan s jednim beskrajnim lancem, postavljenim na uzdužni nosač, a koji je pomoću jednog pogonskog uređaja uzdužno pomičan u uzdužnom smjeru. Ovako izveden uređaj za vuču pragova osigurava pouzdano i brzo pomicanje pragova postavljenih na uređaj za držanje pragova u smjeru prema uređaju za polaganje pragova, pri čemu se uz kratkotrajno postavljanje povlakača na gornju stranu uzdužnog nosača omogućava neometano zahvaćanje gornjeg sloja pragova s vagona za pretovar pragova. This task, according to the invention, is solved by providing a pulling device for thresholds, made to rest on one longitudinal side of a threshold located on a threshold holding device, which is longitudinally movable along the entire length of the holding device by means of a drive device in the direction of the device for placing the sills on the rear side. By combining in the longitudinal direction a movable sleeper traction device with a sleeper placement device placed at the end, a particularly efficient sleeper placement is achieved during the continuous movement of the sleeper placement device. At the same time, in a particularly convenient way, the longitudinal movement of the sleepers held on the sleeper holding device can be performed, parallel to the first one, on the sleeper gripping device placed on the sleeper, using a traction device. In this way, it lies first in order to be used to hold the thresholds, and with the help of a traction device. In this way, the first in line to be gripped and laid down the sleeper is always in the same position, so that, for example, the movement path of the sleeper gripper to perform sleeper laying is always constant, and as short as possible. Another special advantage of the device for laying sleepers according to this invention is that, after laying the last sleeper, the next layer of sleepers can be delivered extremely quickly, whereby the gantry cranes move above the existing wagon for transshipment of the sleepers, and the longitudinal support is simultaneously connected to the holding device of sleepers lowers to download the uppermost layer of sleepers. In a further development of the invention, the device for pulling thresholds is made with at least one puller, designed to rest on one longitudinal side of the thresholds, placed on the device for holding the thresholds, which is connected to one endless chain, placed on a longitudinal support, which is by means of one drive of the device longitudinally movable in the longitudinal direction. The sleeper pulling device designed in this way ensures reliable and fast movement of the sleepers placed on the sleeper holding device in the direction towards the sleeper laying device, whereby with a short-term placement of the puller on the upper side of the longitudinal support, the upper layer of sleepers can be unhindered from the sleeper transshipment wagon.

Jedno daljnje razvojno rješenje izuma ostvareno je tako što je iza uređaja za vuču pragova postavljen uređaj za polaganje pragova izveden od jednog, pomoću jednog pogonskog uređaja poprečno na uzdužni smjer uzdužnog nosača u obliku kliješta pomičnog, uređaja za zahvaćanje pragova, koji je pomoću jednog pogonskog uređaja pomično uležišten u jednoj uzdužnoj vođici. Ovako izvedenim uređajem za zahvaćanje pragova može se izvesti brzo i precizno hvatanje pragova i postavljanje pragova. Na taj način je moguće u obliku kliješta zahvaćanje pragova u oba njegova čelna područja s prednošću neometanja za položaj praga bez utjecaja otvaranja uređaja za zahvaćanje. A further development solution of the invention was achieved by placing a device for laying sleepers behind the sleeper pulling device, made of one, by means of one drive device transverse to the longitudinal direction of the longitudinal support in the form of movable pliers, a sleeper gripping device, which is by means of one drive device movable in one longitudinal guide. With the threshold gripping device designed in this way, quick and precise threshold gripping and threshold setting can be performed. In this way, it is possible in the form of pliers to grip the sills in both of its front areas with the advantage of not interfering with the position of the sill without the influence of the opening of the gripping device.

Slijedeći razvoj izuma sastoji se u tome, što je uzdužna vođica uređaja za zahvaćanje pragova preko dijela dužine, u obliku L profiliranih tračnica izvedenog uređaja za držanje pragova izvedena u obliku konzole. Zbog ove konzolaste konstrukcije potrebno je samo jedno jedino, brzo izvedivo, uzdužno pomicanje uređaja za zahvaćanje radi brzog i točnog polaganja pragova. The following development of the invention consists in the fact that the longitudinal guide of the threshold gripping device over part of the length, in the form of L-shaped profiled rails of the derived threshold holding device, is made in the form of a console. Due to this cantilever construction, only a single, quick, longitudinal movement of the gripping device is required for fast and accurate laying of sleepers.

Jedan daljnji razvoj izuma predstavlja jedan s portalnim dizalicama povezani kotač za mjerenje pređenog puta, za pokretanje pogona za poprečno pomicanje za istodobno postavljanje na oba čelna dijela predviđenog uređaja za zahvaćanje pragova. Pomoću mjerača pređenog puta, može se preko kontinuiranog voženja uređaja za polaganje pragova točno odrediti povratna putanja, tako da se prag koji drži uređaj za zahvaćanje pragova nakon odašiljanja upravljačkog impulsa od strane mjerača pređenog puta pušta da padne u pravilnom, željenom rastojanju pragova. A further development of the invention is a distance measuring wheel connected to the gantry cranes, to actuate the transverse movement drive for simultaneous placement on both fronts of the intended threshold gripping device. With the distance meter, the return path can be accurately determined through the continuous driving of the sleeper device, so that the sleeper held by the sleeper device after the transmission of the control pulse by the travel meter is allowed to fall at the correct, desired distance of the sleepers.

U prijelazno području pragova koji se postavlja s uređaja za držanje pragova na uređaj za zahvaćanje pragova, može se, prema jednoj daljnjoj varijanti izvođenja, za nalijeganje na prag smješten na obje tračnice za držanje pragova, preko daljinski upravljanog impulsa uklonivi graničnik povezati s uređajem za držanje pragova. Ovim se graničnikom može postići točno ograničavanje uzdužnog pomicanja koje izvodi uređaj za vuču na pragovima postavljenim na uređaj za držanje pragova. Preklopnim izvođenjem graničnika omogućeno je neometano prenošenje prvog po redu praga pomoću uređaja za zahvaćanje pragova. In the transitional area of the thresholds, which is placed from the threshold holding device to the threshold gripping device, according to a further variant of the embodiment, in order to abut the threshold located on both threshold holding rails, a removable limiter can be connected to the holding device via a remotely controlled pulse thresholds. With this limiter, it is possible to achieve an accurate limitation of the longitudinal movement performed by the traction device on sleepers mounted on the sleeper holding device. The switchable design of the limiter enables unhindered transfer of the first threshold by means of the device for grasping the thresholds.

Jedno drugo prikladno izvođenje izuma sastoji se u tome, što je između uzdužnog nosača i uređaja za vuču brodova, odnosno uređaja za držanje pragova postavljena jedna granična letva, odnosno letva za amortizaciju, koja je povezana s na uzdužnom nosaču postavljenim pogonom za promjenu rastojanja u odnosu na tračnice za držanje uređaja za držanje pragova. Pomoću takve jedne amortizacijske odnosno granične letve, koja naliježe na gornju stanu praga od uzimanja sloja pragova s vagona za dopremu pragova i u tijeku prenošenja pragova do mjesta polaganja, može se izvesti bez smetnji transport pomoću uređaja za držanje pragova zahvaćenog sloja pragova. Pored toga je ova amortizacijska, odnosno granična šipka zbog neometanog uzdužnog pomicanja pragova pomoću uređaja za vuču, malo pomična u odnosu na gornju površinu pragova, tako da se pouzdano izbjegava podizanje praga izazvano neravnomjernim djelovanjem sila. Another suitable embodiment of the invention consists in the fact that between the longitudinal support and the device for towing ships, i.e. the device for holding thresholds, a boundary bar, i.e. a cushioning bar, is placed, which is connected to a drive installed on the longitudinal support for changing the distance in relation to to the rails to hold the threshold holding device. By means of such a cushioning or boundary batten, which rests on the top floor of the sleeper from the removal of the sleeper layer from the sleeper delivery wagon and during the transfer of the sleepers to the place of laying, the transportation of the affected sleeper layer can be carried out without interference using the sleeper holding device. In addition, due to the undisturbed longitudinal movement of the thresholds by means of a traction device, this cushioning or border bar is slightly movable in relation to the upper surface of the thresholds, so that raising the threshold caused by uneven forces is reliably avoided.

Prema jednom slijedećem izvođenju izuma, napravljen je uređaj za polaganje pragova, koji je neposredno iza uređaja za vuču pragova, od dvije oslanjajuće letve za nalijeganje krajeva praga koji se postavlja, koje su postavljene kod krajeva L oblikovanih tračnica za držanje i koje se pomoću jednog pogona mogu zakretati oko jedne osi koja se pruža u uzdužnom smjeru uzdužnog nosača. Takav uređaj za polaganje pragova karakterističan je po vrlo jednostavnom konstrukcijskom rješenju. According to a further embodiment of the invention, a device for laying thresholds, which is directly behind the device for pulling thresholds, is made of two supporting slats for abutting the ends of the threshold to be installed, which are placed at the ends of the L-shaped holding rails and which are moved using one drive they can rotate around an axis that extends in the longitudinal direction of the longitudinal support. Such a device for laying thresholds is characterized by a very simple design solution.

Izum se, konačno, sastoji od postupka za kontinuirano polaganje pragova na tucanički zastor, kod kojeg se jedan broj, u jednoj vodoravnoj ravnini na pretovarnom vagonu postavljenih pragova zahvaća i, u tijeku transporta do mjesta polaganja, spušta neposredno do iznad razine tucaničkog zatvora, poslije čega se tijekom kontinuiranog kretanja uređaja za polaganje pragova pragovi redaju na dijeljenoj udaljenosti pragova i istodobno se na uređaju za držanje pragova preostali pragovi periodično pomiču u smjeru mjesta polaganja. Posebna prednost postupka prema izumu sastoji se u tome, što se može ostvariti polaganje pragova, zbog vrlo jednostavno ostvarivog skladištenja pragova s jedne strane, i pojednostavljenog odlaganja pragova s vrlo kratkim pomicanjem s druge strane, vrlo efikasno i u kontinuiranom radnom procesu. Finally, the invention consists of a procedure for the continuous laying of sleepers on the tucanic curtain, in which a number of sleepers placed in one horizontal plane on the transshipment wagon are caught and, during transport to the place of laying, lowered immediately above the level of the tucanic prison, after during the continuous movement of the device for laying the thresholds, the thresholds are arranged at a shared distance of the thresholds and at the same time, the remaining thresholds on the device for holding the thresholds are periodically moved in the direction of the place of laying. A special advantage of the process according to the invention is that it is possible to lay the sleepers, due to the very easily achievable storage of the sleepers on the one hand, and simplified placement of the sleepers with a very short movement on the other hand, very efficiently and in a continuous work process.

U slijedećem dijelu će izum biti detaljnije objašnjen preko dva primjera izvođenja. In the next part, the invention will be explained in more detail through two examples of execution.

Na slici 1 prikazan uređaj 1 za polaganje pragova sastoji se od jedne portalne dizalice 2, s njom povezanog, središnje postavljenog, uzdužnog nosača 3, jednog s njime povezanog uređaja 4 za odlaganje pragova i jednog s donje strane uzdužnog nosača 3 postavljenog uređaja 5 za držanje pragova. Dvije bočne strane 8 portalne dizalice 2, koja se može kretati preko kotača 6 s vijcima po kopirnim tračnicama 7, međusobno su povezane poprečnim nosačem 9, koji se pruža poprečno na kopirne tračnice 8, odnosno na bočne zidove 8. Na njemu je postavljena pogonska centrala 10. Za aktiviranje pogonskog uređaja 11 za vožnju i drugih pogonskih uređaja, postavljen je upravljački stol 12 sa sjedištem za rukovatelja. Mjerenje na kopirnim tračnicama 7 izvedenog povratnog hoda u tijeku polaganja pragova vrši se pomoću kotača 13 za mjerenje pređenog puta. Poprečni nosač 9 podesiv je po visini pomoću u bočnim zidovima 8 postavljenih pogonskih uređaja 14, a kod prikazanog primjera njegova visina podizanja iznosi 1,7 m. Pomoću jednog poznatog mehanizma ugrađenog u bočne zidove, ukupna visina portalne dizalice 2, odnosno poprečnog nosača 9, iznosi 3,4 m. The device 1 shown in Figure 1 for laying sleepers consists of one gantry crane 2, connected to it, centrally placed, longitudinal support 3, one connected to it device 4 for laying sleepers and one device 5 placed on the underside of the longitudinal support 3 for holding thresholds. The two sides 8 of the gantry crane 2, which can be moved via wheels 6 with screws along the copying rails 7, are connected to each other by a transverse support 9, which extends transversely to the copying rails 8, i.e. to the side walls 8. The drive unit is placed on it 10. To activate the driving device 11 for driving and other driving devices, a control table 12 with a seat for the operator is installed. The measurement on the copier rails 7 of the performed return stroke during the laying of sleepers is done using the wheel 13 for measuring the distance traveled. The cross beam 9 is adjustable in height using drive devices 14 placed in the side walls 8, and in the example shown, its lifting height is 1.7 m. Using a known mechanism built into the side walls, the total height of the gantry crane 2, i.e. the cross beam 9, is 3.4 m.

Središnji dio poprečnog nosača 9 portalne dizalice 2 povezan je s jednim uzdužnim nosačem 3, paralelnim kopirnim tračnicama 3. Ovaj ima na svojoj donjoj strani dvije međusobno paralelne L profilirane tračnice 15 za držanje, koje se pružaju duž uzdužnog nosača 3, i koje oblikuju uređaj 5 za držanje pragova. One su preko poprečnih vođica 16 i pogona 17 poprečno pomično povezane s uzdužnim nosačem 3. Vodoravni krak 18 obje tračnice za držanje, paralelan kopirnim tračnicama 7 predviđen je za oslanjanje krajeva pragova. Vodoravan krak 9 tračnica 15 za držanje ima u području uređaja 4 za odlaganje pragova manju visinu radi oblikovanja područja 20 za predaju pragova. The central part of the transverse support 9 of the gantry crane 2 is connected to one longitudinal support 3, parallel copying rails 3. This has on its lower side two mutually parallel L profiled rails 15 for holding, which extend along the longitudinal support 3, and which form the device 5 for holding thresholds. They are transversely connected to the longitudinal support 3 via the transverse guides 16 and the drive 17. The horizontal arm 18 of both holding rails, parallel to the copy rails 7, is designed to support the ends of the thresholds. The horizontal arm 9 of the holding rail 15 has a lower height in the area of the device 4 for placing sleepers in order to shape the area 20 for handing sleepers.

S uzdužnim nosačem 3 povezan je uređaj za vučenje pragova. On je izveden s dva povlakača 23, predviđena za nalijeganje na jednu uzdužnu stanu pragova 22 uskladištenih na uređaju 5 za držanje pragova. Povlakači 23 su povezani s beskrajnim lancima 25, postavljenim na uzdužni nosač 3 i pomičnim pomoću pogona 24 u njegovom uzdužnom smjeru. A device for pulling the sleepers is connected to the longitudinal support 3. It is made with two pullers 23, designed to rest on one longitudinal flat of sleepers 22 stored on device 5 for holding sleepers. The pullers 23 are connected to the endless chains 25, placed on the longitudinal support 3 and movable by means of the drive 24 in its longitudinal direction.

Kako je prikazano na slikama 1 i 2, na kraju uzdužnog nosača 3 postavljen je uređaj 4 za odlaganje pragova, koji se u obliku konzole pruža preko uzdužnog nosača 3 i uređaja 5 za držanje pragova, a koji je oblikovan od jednog uređaja 27 za zahvaćanje pragova, koji se pomoću pogona 25 pomiče, u obliku kliješta poprečno na uzdužnu os uzdužnog nosača 3. Uređaj 27 za zahvaćanje pragova je pomoću pogona 28 pomično uležišten u uzdužnoj vođici 29. U prijelaznom području je u ravnini koju oblikuje okomit krak 19 preklopni graničnik 30, koji je načinjen da naliježe na bočnu površinu praga i okreće se putem daljinskog impulsa, povezan s uređajem 5 za držanje pragova. Između uzdužnog nosača 3 i uređaja 5 za držanje pragova postavljena je jedna granična, odnosno amortizacijska letva, koja nije detaljnije prikazana, i koja je povezana s na uzdužnom nosaču 3 pričvršćenim pogonima za promjenu rastojanja u odnosu na tračnicu 15 za držanje. As shown in Figures 1 and 2, at the end of the longitudinal support 3 is placed a device 4 for placing sleepers, which extends in the form of a console over the longitudinal support 3 and device 5 for holding sleepers, and which is formed by one device 27 for engaging sleepers , which is moved by the drive 25, in the form of pliers transversely to the longitudinal axis of the longitudinal support 3. The device 27 for gripping the sills is movably seated in the longitudinal guide 29 by means of the drive 28. In the transition area, in the plane formed by the vertical arm 19, there is a folding stop 30, which is made to rest on the side surface of the threshold and rotates by means of a remote impulse, connected to the device 5 for holding the thresholds. Between the longitudinal support 3 and the device 5 for holding thresholds, one boundary or cushioning bar is placed, which is not shown in detail, and which is connected to the drives attached to the longitudinal support 3 for changing the distance in relation to the rail 15 for holding.

Kako je na slici 3 prikazano crtama crta-točka, uzdužni nosač 3 je izveden tako da može spustiti tračnice 15 za držanje neposredno iznad razine 31 tucaničkog zastora na koji se postavljaju pragovi 22, odnosno do oko gornjeg ruba kopirne tračnice 7. As shown in Figure 3 by dash-dot lines, the longitudinal support 3 is designed so that it can lower the holding rails 15 just above the level 31 of the tucanic curtain on which the thresholds 22 are placed, i.e. up to around the upper edge of the copying rail 7.

U daljnjem tekstu će detaljnije biti objašnjen način rada uređaja 1 za polaganje pragova prema izumu. In the following text, the mode of operation of device 1 for laying thresholds according to the invention will be explained in more detail.

Portalna dizalica 2 će se po aktiviranju voznog postolja 11 odvesti za prijem pragova 22 preko jednog vagona za pretovar pragova koji nije prikazan. Zatim će uzdužni nosač 3 biti toliko spušten dok ne dostigne najviši položaj pragova. Odgovarajućim zajedničkim pomicanjem obiju tračnica 15 za držanje pomoću pogona 17, bit će svi pragovi 22, uskladišteni u jednoj ravnini paralelnoj kopirnim tračnicama 7, zahvaćeni pomoću pogona 14 podignuti i preneseni u smjeru strelice 32 prema području polaganja. U tijeku tog kretanja će se uzdužni nosač 3 zajedno s uređajem 5 za držanje spuštati sve dok donji kraj praga ne bude na udaljenosti od oko 5 do 8 cm od razine 31 tucaničkog zastora. Uređaj 27 za zahvaćanje zahtijeva u smjeru strelice 32 prvi prag 22 u prijelaznom području 20, tako što se obje okomite poluge za zahvaćanje pod djelovanjem pogona 26 pritisnu na čelne površine praga. Graničnik 30 se prevrne u stranu, tako da se zahvaćeni pragovi 22 mogu nesmetano pomaknuti pod djelovanjem pogona 28 preko tračnica 15 za držanje prema van u smjeru strelice 32, u prednji krajnji položaj (vidjeti crtama crta-točka prikazani položaj uređaja 4 za polaganje pragova na slici 1). Portalna dizalica će se kontinuirano kretati u smjeru strelice 33, sve dok mjerač 13 pređenog puta određuje željeni razmak između pragova i odašilje odgovarajući upravljački impuls pogonu 26. Ovo izaziva razmicanje spomenutih zahvatnih poluga uređaja 27 za zahvaćanje, tako da će zahvaćeni prag 23 pasti sa spomenute male visine od oko 5 do 8 cm u pravilan položaj u odnosu na susjedne, već postavljene pragove na tucaničkom zastoru. After activating the undercarriage 11, the gantry crane 2 will be driven to receive sleepers 22 via a wagon for transshipment of sleepers, which is not shown. Then the longitudinal support 3 will be lowered until it reaches the highest position of the sills. By appropriate joint movement of both holding rails 15 by drive 17, all thresholds 22, stored in one plane parallel to the copy rails 7, will be picked up by drive 14 and transferred in the direction of arrow 32 towards the laying area. In the course of this movement, the longitudinal support 3 together with the holding device 5 will be lowered until the lower end of the threshold is at a distance of about 5 to 8 cm from the level 31 of the tucanic curtain. The gripping device 27 requires the first threshold 22 in the transition area 20 in the direction of the arrow 32, so that both vertical gripping levers are pressed against the front surfaces of the threshold under the action of the drive 26. The limiter 30 is turned to the side, so that the affected thresholds 22 can be moved smoothly under the action of the drive 28 over the rails 15 for holding outwards in the direction of the arrow 32, to the front end position (see the position of the device 4 for laying thresholds on Figure 1). The gantry crane will continuously move in the direction of the arrow 33, until the travel meter 13 determines the desired distance between the thresholds and sends the corresponding control pulse to the drive 26. This causes the aforementioned engagement levers of the engagement device 27 to move apart, so that the engaged threshold 23 will fall from the aforementioned of a small height of about 5 to 8 cm in the correct position in relation to the adjacent, already installed thresholds on the Tucan curtain.

U međuvremenu će se graničnik 30 okrenuti nazad, preko vodoravnog kraka 18 tračnice 15 za držanje i aktivirati pogon 24. Ovaj će izvršiti uzdužno pomicanje povlakača 23 uređaja 21 za povlačenje, tako da će svi na tračnicama 15 za držanje uskladišteni pragovi 22 biti uzdužno pomaknuti u smjeru prijelaznog područja do graničnika 30. Čim s njime dođe u dodir prvi prag 22, slijedi upravljački impuls za isključenje pogona 24 uređaja 21 za povlačenje. Pri daljnjem kontinuiranom kretanju portalne dizalice 2 u smjeru 33 ponavlja se opisani postupak polaganja, pri čemu se sada prvi prag 22 zahvaćen uređajem 27 za zahvaćanje, uzdužno pomaknut, i nakon dostizanja pravilnog razmaka između pragova pušten da padne. Nakon polaganja posljednjeg na uređaju 5 za držanje pragova uležištenih pragova 22, portalna dizalica će se odvesti ponovno nad ranije postavljen vagon za pretovar pragova i podići najgornji sloj pragova za daljnje polaganje. In the meantime, the stop 30 will turn back, over the horizontal arm 18 of the holding rail 15 and activate the drive 24. This will perform a longitudinal movement of the puller 23 of the pulling device 21, so that all the thresholds 22 stored on the holding rails 15 will be moved longitudinally in in the direction of the transition area to the limiter 30. As soon as the first threshold 22 comes into contact with it, a control impulse follows to switch off the drive 24 of the pulling device 21. During further continuous movement of the gantry crane 2 in the direction 33, the described laying procedure is repeated, whereby the first sleeper 22 is now grasped by the gripping device 27, moved longitudinally, and after reaching the correct distance between the sleepers, is allowed to fall. After laying the last one on the device 5 for holding sleepers 22, the gantry crane will drive again over the previously placed sleeper transshipment wagon and raise the uppermost layer of sleepers for further laying.

Na slikama 4 i 5 je prikazan u pojednostavljenom jedan sljedeći primjer izvođenja uređaja 34 za polaganje pragova. Na krajnjim dijelovima tračnica 35 za držanje postavljene su, za nalijeganje oba krajnja dijela pragova 36 koji se polažu, oslone letve 37, koje se pomoću pogona 38 mogu zakrenuti oko jedne osi 39 koja se pruža u smjeru tračnice 35 za držanje, odnosno uzdužnog nosača. Na tračnicama 35 za držanje uskladišteni pragovi 36 će se pomoću jednog uređaja za povlačenje prema izumu pomicati do graničnika 40. Nakon dostizanja pravilnog razmaka među pragovima, a pri kontinuiranom kretanju portalne dizalice, dobiva se preko mjerača pređene udaljenosti odgovarajući impuls na pogonu 38, nakon kojeg se obje letve za oslanjanje 37 prevrnu u položaj prikazan crtama crta-točka. U sljedećoj fazi zakretanja unazad obiju letvi za oslanjanje 37, pomaknut će se sakupljeni pragovi 36 na tračnicama 35 za držanje do graničnika 40. Figures 4 and 5 show a simplified example of the next embodiment of the device 34 for laying thresholds. On the end parts of the holding rails 35, support slats 37, which can be rotated by means of the drive 38 around an axis 39 extending in the direction of the holding rail 35, i.e. the longitudinal support, are placed on the end parts of the holding rails 35, for the abutment of both end parts of the thresholds 36 that are being laid. The sleepers 36 stored on the holding rails 35 will be moved to the stop 40 by means of a pulling device according to the invention. After reaching the correct distance between the sleepers, and with the continuous movement of the gantry crane, a corresponding impulse is obtained on the drive 38 via the distance traveled meter, after which both support slats 37 are turned over to the position shown by the dash-dot lines. In the next stage of backward rotation of both support bars 37, the collected sleepers 36 on the support rails 35 will move to the stops 40.
