Um vagão de transporte 1 que pode ser deslocado numa linha 3 por meio de veículos sobre carris 2 apresenta um chassi 4 com uma superfície para transporte de carga 5. Esta serve para o acondicionamento de carris a transportar 6, que são depositados em várias camadas sobrepostas. Num lado longitudinal do chassi 4 - na direção longitudinal do veículo e distanciados entre si - estão dispostos dois guindastes sobre carris 7, que na Fig. 2 são apresentados com maior detalhe.A transport wagon 1 that can be moved in a line 3 by means of rail vehicles 2 has a chassis 4 with a cargo transport surface 5. This is used for the packaging of rails to be transported 6, which are deposited in several overlapping layers . On one longitudinal side of the chassis 4 - in the longitudinal direction of the vehicle and spaced apart from each other - two cranes are arranged on rails 7, which in Fig. 2 are shown in more detail.
Cada guindaste sobre carris 7 é essencialmente constituído por uma coluna de guindaste vertical 8 disposta sobre a superfície de transporte para carga 5 e por uma lança de guindaste fixada sobre esta e horizontalmente giratória 9. Um carro de guindaste 10 - mais evidente na Fig. 3 - está alojado de forma deslocável na direção longitudinal da lança de guindaste 9 e para este efeito apresenta tambores 11, que são concebidos de modo a deslizar sobre carris de lança 12. Além disso está prevista uma roda dentada de acionamento 14 que é ativada por meio de um dispositivo de acionamento 13, que está engrenada numa cremalheira 15 montada na lança de guindaste 9 e serve para o deslocamento do carro de guindaste 10 ao longo da lança de guindaste 9.Each rail crane 7 is essentially constituted by a vertical crane column 8 disposed on the load carrying surface 5 and by a crane boom fixed thereto and horizontally rotatable 9. A crane carriage 10 - most evident in Fig. 3 is housed displaceably in the longitudinal direction of the crane boom 9 and for this purpose has drums 11, which are designed to slide on lance rails 12. In addition there is provided a drive sprocket 14 which is activated by means of a drive device 13, which is meshed with a rack 15 mounted on the crane boom 9 and serves for the displacement of the crane carriage 10 along the crane boom 9.
Uma corrente de carga 16 para a elevação de um carril 6 está posicionada numa extremidade dianteira 17 do carro de guindaste 10 relativamente à referida direção longitudinal distanciada da coluna de guindaste 8 e equipada com uma garra para carris 25 ajustável em altura por meio de dispositivos de acionamento 19. A roda dentada de acionamento 14 pelo contrário está disposta numa extremidade traseira 18 do carro de guindaste 10 na proximidade da coluna de guindaste 8. 4A load chain 16 for lifting a rail 6 is positioned at a forward end 17 of the crane carriage 10 relative to said longitudinal direction spaced apart from the crane column 8 and equipped with a height adjustable rail grip 25 by means of The drive sprocket 14 instead is disposed at a rear end 18 of the crane carriage 10 in the vicinity of the crane 8.
Conforme representado na Fig. 4 numa extremidade 20 da lança de guindaste 9 distanciada da coluna de guindaste 8 está fixada uma lança de guindaste auxiliar 21 que está alojada de forma deslocável na direção longitudinal da lança de guindaste 9 e é ajustável de uma modo fora de serviço para um modo de trabalho. A referida lança de guindaste auxiliar telescópica 21 pode ser retida ou bloqueada em diferentes posições de deslocamento por meio de um dispositivo de retenção 27. Na forma de realização aqui apresentada, construtivamente particularmente fácil a lança de guindaste auxiliar 21 é constituída por dois carris em U (dos quais o dianteiro é suprimido), que estão dispostos de ambos os lados da lança de guindaste 9 e aparafusados a esta. Para este efeito serve um parafuso 22, disposto num orifício oblongo 23 da lança de guindaste 9, de modo a evitar, que a lança de guindaste auxiliar 21 é demasiado extraída despropositadamente. A parte inferior, horizontal do carril em U que forma a lança de guindaste auxiliar 21 além disso tem a função de um carril de rolamento 26. Por conseguinte a lança de guindaste auxiliar 21 apresenta dois carris de rolamento 26 posicionados paralelamente relativamente aos carris de lança 12 da lança de guindaste 9, sobre os quais - que para este efeito são concebidos com um perfil escalonado - podem deslizar tambores 11. A conceção telescópica da lança de guindaste auxiliar 21 proporciona a possibilidade vantajosa de uma adaptação simples, rápida e exata do guindaste sobre carris 7 a espaços, por exemplo no caso da utilização num túnel. Neste sentido a disposição da corrente de carga 16 na extremidade dianteira 17 do carro de guindaste 10 também é 5 particularmente conveniente no caso de atividades de carga e de descarga em túneis. Uma outra vantagem reside no posicionamento da roda dentada de acionamento 14 na extremidade traseira 18 do carro de guindaste 10, considerando que devido a isso a cremalheira 15 não tem de penetrar na secção telescópica da lança de guindaste auxiliar 21 (ver Fig. 4), para assegurar o deslocamento do carro de guindaste 10 até à extremidade dianteira da lança de guindaste 9. Neste âmbito é igualmente significativa a caracteristica, de a distância entre a corrente de carga 16 e a roda dentada de acionamento 14 corresponder a deslocamento s da lança de guindaste auxiliar 21 entre o modo fora de serviço e o modo de trabalho. A Fig. 5 apresenta uma variante de uma lança de guindaste auxiliar 21, que está disposta no interior da lança de guindaste 9 - concebida como tubo moldado 24 - e é telescopicamente extraível. Os carris de lança 12 para os tambores 11 do carro de guindaste 10 neste caso encontram-se na parte superior da lança de guindaste 9.As shown in Fig. 4 at an end 20 of the crane boom 9 spaced from the crane column 8 is secured an auxiliary crane boom 21 which is displaceably housed in the longitudinal direction of the crane boom 9 and is adjustable in a manner outside service for a way of working. Said telescopic auxiliary crane jib 21 can be retained or locked in different displacement positions by means of a holding device 27. In the embodiment shown here, constructively particularly easy the auxiliary crane boom 21 is constituted by two U-rails (of which the front is suppressed), which are arranged on both sides of the crane boom 9 and bolted to it. For this purpose, a screw 22 is disposed in an oblong hole 23 of the crane boom 9, so as to avoid that the auxiliary crane boom 21 is too unplanned. The lower, horizontal part of the U-rail forming the auxiliary crane boom 21 furthermore has the function of a roller rail 26. The auxiliary crane boom 21 therefore has two roller rails 26 positioned parallel to the boom rails 12 of the crane lance 9, on which - which for this purpose are designed with a stepped profile - drums 11 are slidable. The telescopic design of the auxiliary crane lance 21 provides the advantageous possibility of simple, fast and accurate adaptation of the crane on rails 7 through spaces, for example in the case of use in a tunnel. In this regard the arrangement of the load chain 16 at the forward end 17 of the crane carriage 10 is also particularly convenient in the case of loading and unloading activities in tunnels. A further advantage lies in the positioning of the drive sprocket 14 at the rear end 18 of the crane carriage 10, considering that because of this the rack 15 does not have to penetrate the telescopic section of the auxiliary crane lance 21 (see Fig. to ensure the displacement of the crane carriage 10 to the forward end of the crane boom 9. In this context, it is also significant that the distance between the load chain 16 and the drive sprocket 14 corresponds to the displacement s of the crane boom auxiliary crane 21 between the out-of-service mode and the working mode. Fig. 5 shows a variant of an auxiliary crane boom 21, which is arranged inside the crane boom 9 - designed as a molded tube 24 - and is telescopically withdrawable. The jib rails 12 for the drums 11 of the crane carriage 10 in this case are in the upper part of the crane boom 9.
Na Fig. 6 além da lança de guindaste auxiliar 21 a cremalheira 15 para o ajuste do carro de guindaste 10 é igualmente concebida de forma telescópica.In Fig. 6, in addition to the auxiliary crane lance 21, the rack 15 for adjusting the crane carriage 10 is also telescopically designed.
