The invention relates to the technical field of tunnel construction, in particular to a lining trolley.
Background
The existing tunnel lining trolley template assembly, bracket assembly, portal assembly, sideslip mechanism, jacking mechanism, running mechanism, stay bar assembly, ladder platform, hydraulic and electric system and the like. The top template is connected with the bracket assembly through the connecting seat, the design of side form bottom plate extension 10mm directly overlaps with the inverted arch face, and bottom template support jack directly supports in side form bottom plate department. The bracket assembly is an assembled structure and consists of a plurality of cross beams, longitudinal connecting beams, diagonal braces, vertical supports and the like. The bracket assembly is in direct contact with the portal longitudinal beam through the bracket cross beam between the bracket assembly and the portal. The transverse moving mechanism is arranged between the bracket cross beam and the portal longitudinal beam to realize the relative displacement of the template and the portal. A lateral oil cylinder is arranged between the bracket beam and the stay bars, and three groups of lateral oil cylinders are longitudinally arranged on the stay bar assemblies on the left side and the right side respectively. The inner side of the side die is welded with the ear seat and the supporting tube through a pin shaft, the other end of the supporting rod is connected with the bracket cross beam through a pin shaft, the folding structure adopted by the supporting rod is divided into an upper supporting rod and a lower supporting rod, the upper supporting rod and the lower supporting rod are positioned through a positioning pin shaft and a wedge block device, a fine adjustment device is designed at the bottom of the lower supporting rod, a group of supporting rods are designed in the middle of each ring of the die plate, and all the supporting rods are connected into a whole through a longitudinal beam. When the trolley is used for setting up the mould, the lateral oil cylinder is retracted to the minimum value, the upper supporting rod and the lower supporting rod are in a straight line, and a wedge block device is arranged. The bracket, the side mould and the stay bar form a triangle structure, thereby meeting the stress requirement of the trolley during lining. When the trolley is demolded, the positioning wedge blocks of the upper brace rod and the lower brace rod are taken out, the lateral oil cylinder extends to the longest, the brace rods are in a folded state, and the lateral mould is separated from the concrete surface.
The portal structure comprises portal longitudinal beams, portal stand columns, guide sleeves, jacking cylinders and the like. The plurality of portal stand columns are arranged on the portal longitudinal beam through bolts, the guide sleeve is arranged or welded at the end part of the portal longitudinal beam through bolts, one end of the jacking cylinder is connected with the guide sleeve, and the other end of the jacking cylinder is connected with the guide post.
The prior art trolley has the defects of complex integral structure, large number of parts, multiple connecting links, high processing difficulty, low manufacturing efficiency and large error, and the connecting positions of the top die and the bracket assembly all need to be additionally provided with mounting seats. The side forms are directly overlapped with the lined inverted arch surface, so that the overlapping difficulty is high, the construction efficiency is influenced, and the concrete molding surface is easy to generate annular dislocation. The stay bar lug plate at the sealing plate of the side die protrudes out of the sealing plate surface of the arc-shaped connecting plate, and occupies the space of a truck when in delivery, so that the truck is inconvenient to load and transport. The arc-shaped connecting plates at the supporting positions of the side mold and the bottom template supporting jack are too thick, so that the loading and the transportation are inconvenient. The number of the bracket parts is large, the number of the connecting nodes is large, and the structural strength and the rigidity stability are poor. The transverse moving mechanism has the advantages that the contact surfaces of the bracket cross beam and the longitudinal beam are steel surfaces, more contact points and larger friction force are provided; the transverse movement is asynchronous, the transverse movement positioning of the trolley is affected, and the bracket and the template are distorted and deformed when serious. The vertical stay bar subassembly is vertically owing to indulge and link the pipe and link into an entirety, and has 3 groups side direction hydro-cylinders, and when the platform truck stand with transfer the mould, 3 point atress leads to indulging the stay bar and appears the uneven bending deformation's of atress condition easily, and vertical each stay bar length is non-unification and leads to stay bar connecting hole and template ear seat connecting hole to be not aligned, hardly adjusts, the condition that the voussoir hardly installs. And the die receiving space of the side die is small.
Therefore, the lining trolley which has the advantages of simple structure, modularized design, good stability and convenient construction is designed.
