Description
Technical field
The present invention relates to railway tunnel construction mechanical field, particularly relate to a kind of multi-platform railway tunnel Mobile workbench.
Background technology
In Concerning Railway Tunnel Construction construction and railway tunnel Disease Treatment process, usually need Mobile workbench to carry out constructing and renovating process.This Mobile workbench majority adopts welding manner, according to specific tunnel contour size, utilizes the Mobile workbench of the integrally welded formulas of section bar such as angle steel, channel-section steel, i iron.When railway tunnel Disease Treatment, require that speed wants fast, do not affect the normal pass of railway as far as possible, and the Mobile workbench of this integral type is too heavy, mobile inconvenient, operating efficiency is also lower, cause tunnel to renovate cycle stretch-out, the demand of regulation fast can not be met.And this industrial chassis is arranged according to particular tunnel overall size, the boom truck for a tunnel possibly cannot be applied to another tunnel.In addition, the disease position in tunnel is not fixed, thus when carrying out regulation operation, single industrial platform cannot meet the demands.。
Summary of the invention
It is simple and have the Mobile workbench of multilayer working platform that main purpose of the present invention is to provide a kind of structure.
For realizing above-mentioned main purpose, the invention provides multi-platform railway tunnel Mobile workbench, comprise at least two-layer working platform, every layer of working platform all has support frame.Wherein support frame comprises: two crossbeams arranged in parallel to each other; Be arranged between crossbeam and two ends all with the dowel of at least two of crossbeam gun iron link; The column of supporting traverse, and be provided with at least two root posts below every root crossbeam.Column lower end is provided with the draw-in groove that can be connected on its lower floor's working platform crossbeam; The crossbeam of lower floor's working platform is provided with position limiting structure, and restriction draw-in groove is along the movement of bearing of trend on crossbeam of crossbeam.
From above scheme, the support frame supports that working platform is formed by column, crossbeam and dowel, simple and the location that can realize on three-dimensional of structure, the crossbeam utilizing the draw-in groove of upper strata working platform to be connected to lower floor's working platform realizes the splicing of multilayer working platform, method is simple, all more for convenience, the setting of position limiting structure makes upper strata working platform can not move relative to lower floor's working platform, safe and reliable for splicing and dismounting.Different working platformes can be selected to carry out being spliced to form multi-platform boom truck according to dissimilar tunnel structure, meet the needs of practical application.
More concrete scheme is, position limiting structure is trapezoidal protrusion, and trapezoidal protrusion is arranged on the outside of outermost column, and the inclined plane of trapezoidal protrusion is in the face of column.
From above scheme, when upper strata working platform is arranged on lower floor's working platform, draw-in groove can move along inclined plane and utilize trapezoidal protrusion to realize the automatic location of upper strata working platform, and the splicing of working platform is flexibly convenient.
Another more concrete scheme is, along the bearing of trend of crossbeam, the column of upper strata working platform is between outermost two columns of its lower floor's working platform.From above scheme, along the bearing of trend of crossbeam, the column of orlop working platform has maximum span, and the column span of upper strata working platform is all less than the column span of its lower floor's working platform, makes boom truck more firm.
Scheme is more specifically, and on the column of orlop working platform, the bottom of the two side of draw-in groove is all provided with scroll wheel, scroll wheel be axially parallel to bearing of trend.From above scheme, orlop working platform has scroll wheel, boom truck can be moved along the direction perpendicular to crossbeam bearing of trend, namely facilitate boom truck to move along direction, tunnel.
Scheme is more specifically further, and the column of every layer of working platform is all provided with scroll wheel.From above scheme, when upper strata working platform is mounted to lower floor's working platform, scroll wheel can play and guide upper strata working platform along the effect of installing perpendicular to crossbeam direction, further facilitates splicing.
Further scheme is, crossbeam is formed by i iron, and when draw-in groove is stuck on crossbeam, scroll wheel abuts with the lower floor of i iron.From above scheme, utilize scroll wheel to abut with i iron lower floor and can realize working platform edge perpendicular to the location on crossbeam direction, thus the width of draw-in groove can be greater than the width of crossbeam, makes the splicing of working platform flexibly simple and easy further.
Preferably, working platform arranges steel mesh reinforcement, steel mesh reinforcement is welded on crossbeam.As seen from the above, operationally, staff can step down on steel mesh reinforcement and carry out operation, makes construction safer.
Preferably, also comprise side ladder, ladder upper end, side is provided with hook, and hook can hang on the crossbeam of the superiors' working platform.As seen from the above, utilize side ladder staff can climb up the working platform of random layer easily, and side ladder can be installed from boom truck and dismantle easily.
Preferably, along the bearing of trend of crossbeam, the column of upper strata working platform is arranged in the outermost dowel of its lower floor's working platform.As seen from the above, there is when working platform is stitched together dowel to be located thereon the outside of the column of layer working platform, make crossbeam more firm, not yielding to the support of its upper strata working platform.
Preferably, multilayer working platform is three layers or more.As seen from the above, the working platform of more than three layers makes construction operation convenient.
