Abstract
The utility model discloses a stand column of an arch frame dragging track. The stand column comprises a stand column body formed by universal bars and connecting plates in an assembled mode, wherein a supporting platform is arranged on the top of the stand column body, rolling wheels are installed on the top of the supporting platform, and the bases of the rolling wheels are firmly fixed to the supporting platform. According to the stand column of the arch frame dragging track, the stand column body is formed by universal bars and connecting plates in the assembled mode, installation is flexible and convenient, influences on station yard operation are small, disassembly and assembly are convenient, reuse is achieved, and environmental protection performance is good. In addition, due to the rolling wheels arranged on the top of the stand column body, and a guide beam can conveniently slide on the top of the stand column; when the guide beam is erected, only one end of the guide beam needs to be hoisted to the upper portion of the stand column, then, the guide beam is pushed to move above the station yard piecewise by moving on the stand column, the whole guide beam can be conveniently installed, the stand column makes installation of the guide beam of the dragging track more convenient, and erection of the dragging track is facilitated.
Description
Technical field
The utility model relates to across dilatory runway, the particularly pillar construction of dilatory runway in the steel pipe arch bridge construction of station.
Background technology
When construct in field, long-span steel pipe arch bridge spanning existing railway junction, required and railway operation condition restriction by railway electrification safety regulation, cannot move into large-scale hoisting machinery equipment.For solution must not be used the problem of large-scale hoisting machinery, we have adopted above station and have set up dilatory runway, and bracket is placed on dilatory runway, along dilatory runway, pull mode mobile in place.Its bow member does not need to use crane while constructing above field, station, can not exert an influence to railway operation, has well solved the problems referred to above.
Build dilatory runway, need to two rows be set for supporting the column of dilatory runway in field, station.Therefore, provide that a kind of rational in infrastructure to be easy to the pillar construction that dilatory runway builds very necessary.
Utility model content
The utility model is intended to provide a kind of column of being convenient to the dilatory runway of bow member that the dilatory runway of bow member builds.
The column of the dilatory runway of bow member described in the utility model, comprise, pile foundation and by universal rod body and the assembled column body of junction plate, column body bottom is connected with the built-in fitting that pile foundation top arranges by bolt, the support platform arranging at the top of column body, roller is installed in the top of support platform, and base and the support platform of roller fixedly secure.
The column of the dilatory runway of bow member described in the utility model, its column body is assembled by universal rod body and junction plate, flexible for installation, the convenience of column body, little to a station Influence to operation, column dismounting is simultaneously also convenient, after dismounting, universal rod body and junction plate are reusable, have reduced cost, good environmental protection.
In addition, column top braces platform top is provided with roller, and while building dilatory runway, the bottom of nose girder that only need to be above column arranges the track matching with roller, and nose girder just can slide above column easily.While laying nose girder, nose girder, above end is lifted into column, then by the mode of sliding on column, is passed to the overhead of the field of arriving at a station piecemeal, can realize easily the installation of whole nose girder.When it sets up dilatory runway and is positioned at the nose girder in an overhead, station, do not need to use crane, can not exert an influence to a station operation.The pillar construction of the described dilatory runway of bow member makes the easier for installation of dilatory runway nose girder, thereby has facilitated building of dilatory runway.
Accompanying drawing explanation
Fig. 1 is the pillar construction schematic diagram of the dilatory runway of bow member described in the utility model;
Fig. 2 is the lateral view of Fig. 1;
Fig. 3 is the column schematical top view of the dilatory runway of bow member described in the utility model.
The specific embodiment
The column of the dilatory runway of a kind of bow member, as shown in Figure 1, Figure 2, comprise, pile foundation 10 and by universal rod body and the assembled column body 1 of junction plate, column body bottom is connected with the built-in fitting that pile foundation top arranges by bolt, the support platform 2 arranging at the top of column body, roller 3 is installed in the top of support platform, and base 4 and the support platform 2 of roller fixedly secure.
The roller of installing in support platform has four, as Fig. 3, lays respectively at four corners of support platform.By four rolling is set, it can coordinate with nose girder base track by four rolling simultaneously when nose girder moves, and makes nose girder by more stable support, move more steady.
The support platform of column body top can be divided into former and later two, as Fig. 2, Fig. 3, is connected respectively with the universal rod body of side before and after column bodies top, and the top of two support platforms fixedly mounts respectively two rollers.
The universal rod body of column bodies top can bend laterally, and as Fig. 2, the universal rod body of outward expands outwardly the column bodies top strong point, thereby support is more stable, and the area of support platform also can be larger.
In order to strengthen the support strength of support platform pair roller, support platform can arrange upper and lower two block plates, upper steel plate 21 is being arranged side by side plural i iron 23 with lower steel plate 22 with roller position opposite position, by the i iron pair roller being arranged side by side, support, thus the support strength of reinforcement support platform pair roller.
The bearing of trend of steel pipe arch bridge and direction the out of plumb of the extension of field wire road, station due to field, leap station, the restriction of field wire road bearing of trend and the direction of column is often arrived at a station, therefore, the bearing of trend of nose girder may upright supports platform direction become angle, in order to adapt to this needs, the axis of the hard-wired roller in support platform top becomes angle with support platform, make the roller can be consistent with the direction that bridge extends as for the glide direction of nose girder on roller, thereby adapt to better the needs of building of dilatory runway.
