Abstract
The invention relates to bridge construction equipment, in particular to a movable bridge support replacing device which conducts bridge support replacement work. The movable bridge support replacing device comprises a portable frame which can stretch across two adjacent bridge floors, walking wheels are arranged at the bottoms of the two sides of the portable frame, a winch is arranged on a transverse beam of the top of the portable frame, the winch drives a steel wire rope and a lifting hook to ascend and descend, a middle beam parallel to the transverse beam is arranged in the middle of the portable frame, a vertical lifting frame is fixedly connected with the middle of the middle beam, a horizontal transverse track which can be dismounted is arranged at the bottom of the lifting frame, and the transverse track can extend to the top positions of bridge beam piers of the two sides. A sliding flat car which can move in the transverse track is arranged on the transverse track. The device can move along the bridge floor, continuous replacement work can be conveniently carried out on the bridge beam support along the line, operation is flexible and convenient, the replacement efficiency of the support is greatly improved, the construction period is shortened, and the work cost is reduced.
Description
Technical field
The present invention relates to equipment for bridge construction, specifically a kind of for carrying out the movable type bridge bearing replacement device of Bridge Support Replacement operation.
Background technology
In the construction of highway viaduct, before not being placed on pier shaft, bridge floor can bridge pad be placed in to Dun Ding by conventional lifting appliance.Carrying out in bridge inspection and maintenance process, need to change bridge pad time, conventionally by oil pressure Lifting Equipment, bridge floor is propped up, take out old bearing, again new bearing is put between pier shaft and bridge floor, this Renewal process is difficult to, by conventional lifting appliance, bearing is carried out to operation, conventionally need to build complicated fixing feet hand is fixed lifting appliance and carries out operation, its operating efficiency is extremely low, particularly when in the time need to carrying out the bearing replacement of multiple bridge piers along the line, greatly extend construction period, improved construction cost.
Summary of the invention
Technical problem to be solved by this invention is, provides one can carry out Bridge Support Replacement operation, and flexible operation, convenience, movable type bridge bearing replacement device that operating efficiency is high.
Movable type bridge bearing replacement device of the present invention includes one can be across the portal frame between adjacent two width bridge floors, and portal frame two side bottoms are provided with road wheel, in portal frame top cross beam, hoist engine are installed, and hoist engine drives wire rope and hook lifting; Described portal frame middle part is provided with the central sill parallel with crossbeam, and central sill middle part is fixedly connected with vertical suspension bracket, and suspension bracket bottom is provided with the cross track of dismountable level, and cross track can extend to bridge pier top position, both sides; On described cross track, be mounted with the sliding plate car that can move along cross track, hoist engine can be hung bridge pad to sliding plate car or by the bridge pad on sliding plate car and sling by suspension hook.
Described hoist engine is arranged on also can be along cross slide way transverse shifting on the cross slide way on crossbeam.
Described cross track is through the laterally steering cover and suspension bracket socket of suspension bracket lower end, cross track can be regulated and suspension bracket between horizontal installation site.
The present invention can move along bridge floor, easily bridge pad along the line is changed to operation continuously, and its flexible and convenient operation has improved the replacing efficiency of bearing greatly, has shortened construction period, has reduced operating cost.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention in bridge end face direction.
The specific embodiment
As shown in the figure, this movable type bridge bearing replacement device includes one can be across the portal frame 1 between adjacent two width bridge floor L, portal frame two side bottoms are provided with road wheel 2, and hoist engine 4 is installed in portal frame top cross beam 3, and hoist engine drives wire rope 5 and suspension hook 6 liftings; Described portal frame 1 middle part is provided with the central sill parallel with crossbeam 7, and central sill middle part is fixedly connected with vertical suspension bracket 8, and suspension bracket bottom is provided with the cross track 9 of dismountable level, and cross track 9 can extend to bridge pier top position, both sides; On described cross track 9, be mounted with the sliding plate car 10 that can move along cross track, hoist engine 4 can be hung bridge pad Z to sliding plate car or by the bridge pad Z on sliding plate car and sling by suspension hook.Described hoist engine 4 is arranged on also can be along cross slide way transverse shifting on the cross slide way on crossbeam.Described cross track 9 is through the laterally steering cover 11 and suspension bracket socket of suspension bracket 8 lower ends, cross track 9 can be regulated and suspension bracket 8 between horizontal installation site.
As shown in Figure 1, the present invention is in the time carrying out Bridge Support Replacement operation, first pass through oil pressure Lifting Equipment S by the bridge floor L at bridge pier D place jack-up from old bearing, then portal frame is placed between the two two width road surfaces that walk abreast, sliding plate car 10 is moved to Dun Ding place along cross track 9 to be moved to old bearing on sliding plate car, in the middle of sliding plate car being moved to, sling and shifted out by hoist engine in suspension hook below again, then packs new bearing into Dun Ding by inverse process.After the bearing replacement of a bridge pier completes, sliding plate car and cross track can be pulled down, then portal frame be longitudinally moved to next bridge pier place along bridge floor, carry out the replacing of next bearing.
