Description

Invenţia se referă la construcţie, în particular la poduri telescopice mobile, şi poate fi utilizată la instalarea construcţiei de pod peste un obstacol. The invention relates to construction, in particular to mobile telescopic bridges, and can be used in the installation of the bridge construction over an obstacle.

Este cunoscut un complex de poduri mecanizat, care constă din construcţii de poduri detaşabile, maşină de asamblat poduri pentru asamblarea şi montarea peste un obstacol a construcţiei de pod şi transportator pentru transportarea elementelor construcţiei de pod. Maşina de asamblat poduri este dotată cu o macara oscilantă (cu braţ mobil în plan vertical). Construcţia de pod include o grindă portantă de montare secţionată şi o suprastructură secţionată, care poate fi asamblată din blocuri de pod, ce constau din două secţiuni de ecartament [1]. A mechanized bridge complex is known, which consists of removable bridge structures, a bridge assembly machine for assembling and mounting the bridge structure over an obstacle, and a conveyor for transporting the bridge structure elements. The bridge assembly machine is equipped with an oscillating crane (with a movable arm in the vertical plane). The bridge structure includes a sectioned mounting load-bearing girder and a sectioned superstructure, which can be assembled from bridge blocks, consisting of two gauge sections [1].

Complexul este destinat asamblării şi montării peste un obstacol a trecerilor din poduri cu lungimea de 41 m capabile să asigure trecerea tehnicii grele, de exemplu, a tancurilor. Ca urmare, complexul şi construcţia de pod necesită o mare cantitate de materiale şi de energie. The complex is intended for assembling and installing over an obstacle 41 m long bridge crossings capable of ensuring the passage of heavy equipment, for example, tanks. As a result, the complex and the construction of the bridge require a large amount of materials and energy.

Problema pe care o rezolvă prezenta invenţie constă în crearea unui pod telescopic mobil simplu în ceea ce priveşte construcţia, montarea şi exploatarea pentru a asigura posibilitatea organizării sau restabilirii rapide a legăturii pentru pietoni şi/sau pentru transportul de mic tonaj peste obstacole înguste. The problem solved by the present invention consists in creating a simple mobile telescopic bridge in terms of construction, assembly and operation to ensure the possibility of organizing or quickly re-establishing the connection for pedestrians and/or for light tonnage transport over narrow obstacles.

Problema se soluţionează prin aceea că podul telescopic mobil conţine un şasiu mobil, pe care este instalată o platformă, pe marginile căreia transversal podului în proces de instalare sunt instalaţi stâlpi verticali; o macara oscilantă, amplasată pe platformă; două grinzi paralele telescopice portante, fixate articulat de marginea platformei, capetele secţiunilor terminale ale cărora sunt unite cu o grindă transversală, pe care, sub secţiunile terminale, sunt instalate suporturi telescopice hidraulice. Pe grinzi este fixată o podină, care cu ajutorul unor cilindri hidraulici de execuţie este unită cu stâlpii. Pe platformă este amplasat un complet de plăci în benzi în formă de U, distanţa interioară dintre poliţele cărora corespunde distanţei dintre marginile exterioare ale secţiunilor grinzilor. The problem is solved by the fact that the mobile telescopic bridge contains a mobile chassis, on which a platform is installed, on the edges of which vertical pillars are installed transversely to the bridge during the installation process; an oscillating crane, located on the platform; two parallel telescopic load-bearing beams, hingedly fixed to the edge of the platform, the ends of the end sections of which are connected to a transverse beam, on which, under the end sections, hydraulic telescopic supports are installed. A platform is fixed on the beams, which is connected to the pillars with the help of hydraulic execution cylinders. A set of U-shaped strip plates is placed on the platform, the inner distance between the shelves of which corresponds to the distance between the outer edges of the beam sections.

Avantajele invenţiei constau în următoarele. Executarea grinzilor portante telescopice dă posibilitate de a efectua prelungirea acestora cu o mărime ce corespunde lăţimii obstacolului care urmează a fi acoperit. Unirea prin articulaţie a grinzilor cu platforma şi unirea podinii lor cu stâlpii dă posibilitate de a micşora gabaritele de transport ale podului mobil. Prezenţa macaralei oscilante dă posibilitate de a efectua montarea pe secţiuni a grinzilor portante amplasate pe platforma plăcilor în benzi, forma şi gabaritele cărora exclud deplasările laterale ale acestora faţă de grinzi, ceea ce măreşte siguranţa podului construit. Unirea capetelor secţiunilor terminale ale grinzilor cu grinda transversală măreşte rigiditatea şi stabilitatea tridimensională a construcţiei transversale a podului. Prezenţa suporturilor hidraulice telescopice sub capetele secţiunilor terminale ale grinzilor dă posibilitate de adaptare la relieful localităţii şi de instalare a podului de trecere fără înclinare transversală, ceea ce sporeşte calitatea şi siguranţa trecerii în ansamblu. The advantages of the invention are as follows. The execution of telescopic load-bearing beams makes it possible to extend them by a size corresponding to the width of the obstacle to be covered. The articulation of the beams with the platform and the connection of their deck with the pillars makes it possible to reduce the transport dimensions of the mobile bridge. The presence of the oscillating crane makes it possible to mount the load-bearing beams placed on the platform of the strip plates in sections, the shape and dimensions of which exclude their lateral displacements relative to the beams, which increases the safety of the constructed bridge. The connection of the ends of the terminal sections of the beams with the transverse beam increases the rigidity and three-dimensional stability of the transverse construction of the bridge. The presence of telescopic hydraulic supports under the ends of the terminal sections of the beams allows for adaptation to the locality's relief and installation of the overpass without transverse inclination, which increases the quality and safety of the crossing as a whole.

Astfel, soluţia constructivă a podului mobil propusă dă posibilitate de a rezolva problema în cauză. Thus, the proposed constructive solution of the drawbridge makes it possible to solve the problem in question.

Urmează un exemplu de executare concretă a invenţiei, care în niciun mod nu reduce aria drepturilor, reflectată în revendicările invenţiei. În calitate de obstacol a fost ales un râu. Şasiul mobil este executat remorcabil, suspendat, autopropulsat, etc. The following is an example of a concrete implementation of the invention, which in no way reduces the scope of the rights reflected in the claims of the invention. A river was chosen as an obstacle. The mobile chassis is made towable, suspended, self-propelled, etc.

Invenţia se explică prin desenele din fig. 1-3, care reprezintă: The invention is explained by the drawings in Fig. 1-3, which represent:

- fig. 1, vederea de sus (planul) a podului prelungit; - Fig. 1, top view (plan) of the extended bridge;

- fig. 2, vederea dintr-o parte (vederea A din Fig. 1) a podului în proces de montare (a trecerii în construcţie); - Fig. 2, side view (view A in Fig. 1) of the bridge in the assembly process (going into construction);

- fig. 3, secţiunea plăcilor în benzi în formă de U. - Fig. 3, section of U-shaped strip plates.

Podul telescopic mobil conţine un şasiu mobil 1, pe care este instalată o platformă 2, pe marginile căreia transversal podului în proces de instalare sunt instalaţi stâlpi verticali 3. Pe platformă este amplasată o macara oscilantă 4, care poate avea braţ telescopic şi/sau se poate deplasa pe platformă, iar în exemplul concret de realizare a invenţiei prezentat ea este instalată pe unul dintre stâlpii verticali 3. De marginea platformei 2 sunt fixate articulat două grinzi 5 paralele telescopice portante, capetele secţiunilor 6 terminale ale cărora sunt unite cu o grindă transversală 7, pe care, sub secţiunile 6 terminale, sunt instalate suporturi 8 telescopice hidraulice. Pe grinzile 5 este fixată o podină 9, care cu ajutorul unor cilindri 10 hidraulici de execuţie este unită cu stâlpii 3. Pe platforma 2 este amplasat un complet de plăci 11 în benzi în formă de U, distanţa interioară dintre poliţele cărora corespunde distanţei dintre marginile exterioare ale secţiunilor grinzilor 5. Pentru asigurarea planităţii în direcţie longitudinală a plăcilor 11 instalate pe secţiunile prelungite ale ambelor grinzi 5 pot fi puse piese de legătură în formă de U, executate de înălţime diferită, sau grinzile de suport 12 pentru plăcile 11 ale fiecărei secţiuni se pot executa de diferite înălţimi (în figuri nu este indicat). Plăcile 11 conţin elemente de construcţie cunoscute pentru unirea lor una cu cealaltă şi/sau întărirea de secţiunile grinzilor 5, care nu constituie obiectul invenţiei. Este evident că pentru asigurarea lucrului mecanismelor de execuţie ale podului mobil este nevoie de echipament suplimentar, cu care acesta este înzestrat. Dar acestea sunt oricare soluţii tehnice cunoscute şi aplicabile, care nu constituie obiectul invenţiei. The mobile telescopic bridge contains a mobile chassis 1, on which a platform 2 is installed, on the edges of which vertical pillars 3 are installed transversely to the bridge during installation. An oscillating crane 4 is placed on the platform, which may have a telescopic arm and/or may move on the platform, and in the concrete embodiment of the invention presented it is installed on one of the vertical pillars 3. Two parallel telescopic load-bearing beams 5 are articulatedly fixed to the edge of the platform 2, the ends of the terminal sections 6 of which are joined with a transverse beam 7, on which, under the terminal sections 6, hydraulic telescopic supports 8 are installed. A platform 9 is fixed on the beams 5, which is connected to the pillars 3 by means of hydraulic execution cylinders 10. A set of plates 11 in U-shaped strips is placed on the platform 2, the inner distance between the shelves of which corresponds to the distance between the outer edges of the sections of the beams 5. To ensure the flatness in the longitudinal direction of the plates 11 installed on the extended sections of both beams 5, U-shaped connecting pieces can be placed, made of different heights, or the support beams 12 for the plates 11 of each section can be made of different heights (not shown in the figures). The plates 11 contain known construction elements for their connection with each other and/or reinforcement of the sections of the beams 5, which do not constitute the subject of the invention. It is obvious that to ensure the operation of the execution mechanisms of the mobile bridge, additional equipment is needed, with which it is equipped. But these are any known and applicable technical solutions, which do not constitute the subject matter of the invention.

Podul telescopic mobil se utilizează în modul următor. The mobile telescopic bridge is used in the following way.

El se aduce la locul trecerii alese. Totodată, în poziţie de transportare grinzile 5 sunt în stare strânsă şi cu ajutorul cilindrilor 10 hidraulici de execuţie sunt ridicate în poziţie verticală. Podul mobil telescopic se instalează pe o parte a sectorului de trecere ales. În funcţie de relieful părţii opuse a trecerii, care urmează a fi instalată cu ajutorul cilindrilor 10, se efectuează coborârea grinzilor 5 sub un unghi anumit. Se efectuează prelungirea secţiunilor 6 grinzilor 5 de lungimea necesară şi cu ajutorul suporturilor 8 telescopice hidraulice se efectuează rezemarea secţiunilor 6 terminale ale grinzilor 5. Pentru evitarea înclinării transversale a trecerii, care se află în construcţie, în funcţie de relief se reglează mărimea prelungirii fiecărui suport 8. Pe şasiul mobil 1 sau platforma 2 cu suportul 13, precum şi pe grinda transversală 7, care uneşte capetele secţiunilor 6 terminale, se instalează lespezi-scări de intrare-ieşire 14, care în afară de funcţiile lor mai au rol de contragreutate în timpul montării construcţiei de pod. It is brought to the chosen passage place. At the same time, in the transport position the beams 5 are in a compressed state and with the help of the hydraulic cylinders 10 of execution are raised to a vertical position. The telescopic mobile bridge is installed on one side of the chosen passage sector. Depending on the relief of the opposite side of the passage, which is to be installed with the help of the cylinders 10, the beams 5 are lowered at a certain angle. The sections 6 of the beams 5 are extended to the required length and the terminal sections 6 of the beams 5 are supported by hydraulic telescopic supports 8. In order to avoid the transverse tilt of the passage under construction, the size of the extension of each support 8 is adjusted depending on the relief. On the mobile chassis 1 or platform 2 with the support 13, as well as on the transverse beam 7, which connects the ends of the terminal sections 6, entrance-exit stair slabs 14 are installed, which, in addition to their functions, also have the role of counterweight during the assembly of the bridge structure.

Astfel, prin prezenta invenţie este rezolvată problema pusă de creare a unui pod telescopic mobil peste obstacole înguste simplu în ceea ce priveşte construcţia, montarea şi exploatarea. Thus, the present invention solves the problem of creating a mobile telescopic bridge over narrow obstacles that is simple in terms of construction, assembly and operation.
