Abstract

The invention discloses a rotatable soffit formwork structure of a bridging machine. The soffit formwork structure is characterized in that: the rotatable soffit formwork structure is designed into three sections, namely, a left soffit formwork, an intermediate rotatable formwork and a right soffit formwork; a rotatable oil cylinder is connected to a bottom portion of the right soffit formwork; the rotatable oil cylinder has a piston rod connected to a bottom portion of the intermediate rotatable formwork; the left soffit formwork, the intermediate rotatable formwork and the right soffit formwork are dismountably connected by pin shafts; after one pin shaft is dismounted, the intermediate rotatable formwork rotates in a vertical plane to be in a vertical state with another pin shaft as a center and under the driving of the piston rod, as a result, the distance of outward movement of main beams is shortened, so is the time of the movement of the main beams, thereby, the soffit formwork structure can assist in improving work efficiency of the bridging machine, reducing load of a loading support, and facilitating construction in a site where the distance for a bridging machine to stretch a formwork to both sides is limited.

Description

The turning bed die structure of bridge fabrication machine

Technical field

The present invention relates to the turning bed die structure of bridge fabrication machine

Background technology

In bridge construction, after a joint bridge cast finished, bridge fabrication machine needed vertical shift to construct to next joint bridge place, when the bridge fabrication machine vertical shift; In order to let bed die avoid bridge pier, the bridge fabrication machine girder will drive bed die direction motion laterally and open, and existing bridge fabrication machine, bed die are divided into two sections designs; Separate from the middle when opening, during the bridge fabrication machine vertical shift, the bridge fabrication machine girder needs to open to both sides the distance of half length of bed die; In the time of guaranteeing just that bed die is crossed bridge pier not can with the bridge pier interference that bumps, increased the carriage load like this, influenced the stability of bridge fabrication machine; On the massif or when dense population areas is constructed, bridge fabrication machine is restricted to the die sinking distance of both sides, and construction is inconvenience very; Simultaneously, move laterally time of cost of girder is longer, has influenced the efficient of bridge fabrication machine work

Summary of the invention

the purpose of this invention is to provide minimizing to the die sinking of both sides distance, reduce the turning bed die structure of the higher bridge fabrication machine of carriage load, operating efficiency.

are for achieving the above object; The present invention provides the turning bed die structure of bridge fabrication machine; Said bridge fabrication machine comprise the bilateral symmetry fixed mount be located at a pair of carriage that rise to support whole loadings on the bridge pier, can be at a pair of propelling dolly that said a pair of carriage top left moves right, be seated in and be used to support whole a pair of girder of striding bridge on the said a pair of propelling dolly, be used for the crossbeam that colligation can be carried out the bed die of the reinforcing bar of concrete-bridge cast, be connected the said bed die of supporting between the said a pair of girder; The turning bed die structure of said bridge fabrication machine comprises left bed die that left and right sides relative fixed is provided with and right bed die, is connected the turning template in centre of said left bed die and said right bed die; The turning template of said left bed die and said centre, the turning template of said right bed die and said centre link together through dismountable bearing pin; Have the state of closing up and open mode according to the said bed die of detachable connection; When said bed die is in when closing up state; Said left bed die, said right bed die, the turning template in said centre link together; It is inboard that said a pair of girder is positioned at said a pair of carriage; When said bed die was in open mode, a said bearing pin between said left bed die, said right bed die, the turning template in said centre was disassembled, and the turning template in said centre turns to vertical state downwards around another said bearing pin; Said a pair of girder deviates from each other under the drive of said a pair of propelling dolly and moves to the said a pair of carriage outside, forms one section lateral separation space between said left bed die, the said right bed die.

preferably; The turning bed die structure of said bridge fabrication machine also comprises the overturning oil cylinder that is fixedly connected on said right bed die bottom, said overturning oil cylinder have be connected with the turning template in said centre be used to promote the piston rod that the turning template in said centre is rotated on vertical plane around said bearing pin.

Because technique scheme is used, the present invention compared with prior art has advantage and effect: bed die is divided into three sections, and left bed die and middle turning template, right bed die and middle turning template link together through dismountable bearing pin ; After a bearing pin dismounting; Middle turning template is that the center of circle rotates to vertical state in vertical direction with another bearing pin, and then during the bridge fabrication machine vertical shift, the bridge fabrication machine girder only needs open 1/3rd of bed die length to both sides; When bed die is crossed bridge pier just not can with the bridge pier interference that bumps; Reduce the carriage load like this, made things convenient for the construction in the both sides die sinking distance workplace that is restricted, simultaneously; The reduced distances girder run duration that girder moves laterally reduces, and has improved the efficient of bridge fabrication machine work.

Description of drawings:

Accompanying drawing 1 master during for separated position of the present invention looks sketch map;

Master when accompanying drawing 2 closes up state for the present invention looks sketch map;

The specific embodiment:

are referring to shown in Figure 1; A pair of carriage 1 bilateral symmetry of bridge fabrication machine is fixed on the bridge pier both sides and is used to support whole load, but at a pair of carriage 1 top the travelling car 2 of a pair of side-to-side movement is set, and a pair of girder 3 is seated in the top of a pair of travelling car 2; And can move along left and right directions with a pair of travelling car; Between a pair of girder 3, be connected with crossbeam 4, be used for colligation and can carry out the bed die of the reinforcing bar of concrete-bridge cast and be supported on a pair of girder 3 and crossbeam 4, bed die is designed to 7 three sections of left bed dies 5, right bed die 6, middle turning template; Left side bed die 5 is connected through bearing pin 9 with middle turning template 7 through bearing pin 10, right bed die 6 with middle turning template 7; Bearing pin 9,10 is detachable, is fixed with overturning oil cylinder 8 in right bed die 6 bottoms, and overturning oil cylinder 8 has the telescopic piston rod 11 that connects middle turning template 7; During bridge construction; Bed die is in and closes up state, and piston rod 11 extend out to long status, and left bed die 5, right bed die 6, middle turning template 7 link together.

Referring to shown in Figure 2, during bridge fabrication machine vertical shift via hole, bed die is in open mode; Pull down pin 10; Untie being connected of left bed die 5 and middle turning template 7, overturning oil cylinder 8 piston rod 11 shorten, and turning template 7 turns to plumbness around bearing pin 9 in the middle of driving on vertical plane; A pair of girder 3 deviates from the outside that moves to a pair of carriage 1 each other under the drive of a pair of propelling dolly 2; At this moment, form the segment distance space that the tolerable bridge pier passes through between left bed die 5 and the right bed die 6, but bridge fabrication machine vertical shift via hole
