Abstract
The utility model provides a closed railway single line lining cutting formworking jumbo of portal, includes, top mould, platform hang, portal, side forms, hydraulic system, formwork support, traveling system and landing stage, the bottom of portal be equipped with the horizontal supporting beam in bottom, the horizontal supporting beam's in bottom horizontal component be located the below of landing stage, the closed railway single line formworking jumbo of a portal, the horizontal supporting beam in bottom makes the portal form confined atress support ring, fundamentally has solved railway single line platform truck portal lower extreme and has easily inwards convergeed the problem, has improved formworking jumbo's the stress situation, has increased the rigidity and the stability of platform truck. The utility model discloses both the effectual horizontal supporting beam in bottom that has avoided made the structure of platform truck be unlikely to to influence the current of vehicle again, had avoided the interference of construction process. Examine the calculation through finite element analysis, intensity, economy is suitable for under the condition that satisfies site operation user demand, the assurance enough intensity of product structure and rigidity.
Description
technical field:
The utility model relates to a kind of railway single lining template trolley for baffle, the closed railway single lining template trolley for baffle of especially a kind of door frame.
background technology:
During the construction of railway single tunnel double-lining, the construction machineries such as current large-scale excavator, loader are needed in hole, traditional lining template trolley for baffle door frame need reserve vehicle passage, thus cause lining template trolley for baffle door frame can not close into ring, the easy toe-in in door frame lower end (being commonly called as leg soft), affects two lining construction qualities.During particularly less section, owing to crossing the restriction of car headroom, design strength is more vulnerable to space constraints, and this just proposes higher requirement to the headroom that is open to traffic of lining template trolley for baffle.During two lining constructions, traditional method adopts in bottom manually to perform earth anchor support bar, and process is numerous and diverse, efficiency is low, constrains on-the-spot speed of application.Therefore provide the new type formwork lining trolley of a kind of applicable single-track railway tunnel lining, Stability Analysis of Structures, saving human assistance necessary.
utility model content:
In order to solve the problem, the utility model provides the closed railway single lining template trolley for baffle of a kind of door frame.
The utility model solves the technical scheme that its technical problem adopts:
The enclosed railway single lining template trolley for baffle of a kind of door frame, comprise, backform, platform hang, door frame, Bian Mo, hydraulic system, shuttering supporting, running gear and trestle, and the bottom of described door frame is provided with bottom bolster, and the horizontal component of described bottom bolster is positioned at the below of trestle.
Door frame is surrounded enclosed construction by described bottom bolster.
Described trestle and door frame pass through HYDRAULIC CONTROL SYSTEM.
Owing to adopting technical scheme as above, the utility model has following superiority:
The closed railway single formwork jumbo of a kind of door frame described in the utility model, bottom bolster makes door frame form closed stressed support ring, fundamentally solve the easy toe-in problem in railway single chassis door frame lower end, improve the overall force-bearing situation of formwork jumbo, add rigidity and the stability of chassis.The utility model had both effectively avoided bottom bolster, made again the structure of chassis be unlikely to affect the current of vehicle, avoided the interference of working procedure.Through finite element analysis, intensity inspection calculate, when meet site operation user demand, ensure product structure sufficient intensity and rigidity economic and practical.
accompanying drawing illustrates:
Fig. 1 is this chassis front view;
Fig. 2 is this chassis right view;
Fig. 3 is this chassis top view;
In figure: 1, backform; 2, platform hangs; 3, translation system; 4, door frame; 5, Bian Mo; 6, hydraulic system; 7, shuttering supporting portion; 8, running gear; 9, trestle; 10, bottom bolster.
detailed description of the invention:
Can explain the utility model in more detail by the following examples, open the purpose of this utility model is intended to protect all changes and improvements within the scope of the utility model, and the utility model is not limited to the following examples;
The closed railway single formwork jumbo of a kind of door frame described by reference to the accompanying drawings, comprise: backform 1, platform hang 2, door frame 4, limit mould 5, hydraulic system 6, touch plate support portion 7, running gear 8 and trestle 9, the bottom of described door frame 4 is provided with bottom bolster 10, the horizontal component of described bottom bolster 10 is positioned at the below of trestle 9, make chassis door frame 4 close into ring, well adapt to the construction characteristic in light section railway single tunnel.
Door frame 4 is surrounded enclosed construction by described bottom bolster 10.
Described trestle 9 is controlled by hydraulic system 6 with door frame 4.
When this chassis lining cutting, first operating hydraulically operated backform 1 and Bian Mo 5 adjust to suitable position, then to be horizontally slipped the center making platform hang 2 adjustment chassis profiles by translation system 3, make chassis in place, and put down trestle 9, to facilitate vehicle pass-through in hole, when lining cutting completes, after concrete curing sufficient intensity, chassis sloughs backform 1 and Bian Mo 5, lifting trestle 9, start line walking system 8, carries out the concrete lining of next group.
Carefully do not state part in upper content for prior art, therefore do not run business into particular one and state.
