Abstract
The utility model is a device for replacing bridge rubber supporting seat belonging to the bridge maintenance equipment field. The utility model consists of a gas bag, a gas-filling device and a controllable gas valve connected between the gas bag and the gas-filling device. The gas-filling device inflates to the gas bag and the gas bag is expanded after inflating to lift the wall plate upwards from the rubber bearing; the gas released from the gas bag after replacing the rubber bearing puts the wall plate down on a new rubber bearing; the rubber bearing replacing is finished after the gas bag is taken out. The utility model has a simple structure, convenient operation, high efficiency and low producing and using cost; the utility model is suitable for the rubber bearing replacing in various bridges.
Description
Technical field
The utility model relates to the device that a kind of replacing is installed in the bridge pad between bridge beam slab and the bent cap.Belong to the bridge maintenance apparatus field.
Background technology
Chinese patent ZL00108445.3 has proposed a kind of " method for maintaining of bridge pad and device ", its device connects into whole fixed mount by upper and lower brake holding by strut, through jack with by joist, junction plate by straight, tiltedly connecting rod connects into integral body, is fixed on and constitutes omnipotent adjustable shelf on the base plate, and be close to by omnipotent adjustable shelf lower end base plate and embrace on the straight line portion of holder two ends, pass a through hole of embracing in the holder with bolt and be fixedly connected into whole carriage with nut and form.During use fixed mount is fixed on the bridge pier column, on fixed mount,, by carriage the bridge board jack-up of integral body is changed then with the direct jack-up carriage of jack.The shortcoming of this method is employed apparatus structure complexity, the load bearing requirements height, thereby cost of manufacture is big; Installation procedure is many during use, and operation easier is big, time-consuming consumption power and cause the use cost height.
The utility model content
The purpose of this utility model is the above-mentioned shortcoming that overcomes prior art, and a kind of device of changing bridge rubber bearing is provided.This replacing apparatus structure is simple, easy to use and be easy to control.
The device of this replacing bridge rubber bearing by air bag, charger and be connected in air bag and charger between the controllable type valve constituted.At first the air bag of unaerated is placed on during work in the gap on the bridge rubber bearing next door that the desire between beam slab joint and the bent cap changes, then by charger to airbag aeration, air bag is filled with air expansion, beam slab upwards is raised up to stops to airbag aeration when leaving neoprene bearing, close the controllable type valve, keep the swelling state of air bag, promptly keep beam slab to be in the position of leaving neoprene bearing, take out the neoprene bearing that desire is changed, insert new bearing, operation controllable type valve slowly discharges the gas in the air bag, beam slab is transferred to new neoprene bearing under the effect of deadweight, continue to open the controllable type valve and discharge gas, treat to take out the replacing that air bag is promptly finished neoprene bearing after the air bag volume-diminished.
Described air bag can be one, be placed on the centre of the neoprene bearing of the both sides beam slab under each beam slab joint from laterally running through of bridge, partly lift on the whole together with shop bridge floor thereon the beam slab end that air bag will dock in twos during inflation, in the replacing that guarantees to finish under the intact situation of bridge floor part neoprene bearing.
Described air bag can also be several, and the controllable type valve of each air bag is controlled by a central controller.Vertically each air bag is placed on respectively under the beam slab joint of butt joint in twos from bridge during use, control by central controller, all keep synchronous consistent when making each airbag aeration with venting, also just make the lifting height of each beam slab of institute's jack-up keep synchronous unanimity, kept the falling head of each beam slab consistent synchronously during venting.Can under the intact situation of bridge floor that guarantees to be laid on the beam slab, finish the replacing of neoprene bearing equally.Another benefit of this practice is in the time only need changing other neoprene bearing, only needs the indivedual air bags of single use, makes operation more easy.
Compared with the aforementioned existing similar products, the utility model has the advantages that easy work simple in structure, easy to operation, the work efficiency height, making and use cost are all low.Be applicable to the neoprene bearing replacing in the different types of rridges.
Content of the present utility model further illustrates with the following Examples, but content of the present utility model is not limited only to content related among the embodiment.

Fig. 1 is a structural representation of the present utility model
Fig. 2 is that air bag is from being placed on the user mode schematic diagram under each beam slab joint laterally running through of bridge
Fig. 3 is with the beam slab top station schematic diagram when the neoprene bearing behind the airbag aeration
Fig. 4 is the structural representation of a plurality of air bags
Fig. 5 is the user mode schematic diagram of a plurality of air bags
The specific embodiment
Referring to Fig. 1, the device of this replacing bridge rubber bearing by air bag 1, charger 3 and be connected in air bag and charger between controllable type valve 2 constituted.The controllable type valve 2 optional electromagnetic valves of using.Charger 3 can be selected air compressor for use.Air bag 1 can be made into the device of shifting block type air bag with rubber type of material, and the benefit of doing like this is to make things convenient for putting into of air bag, can guarantee also simultaneously behind the airbag aeration that being good ground with the upper surface of the soffit of beam slab and bent cap contacts stressed.What Fig. 2 provided is that air bag 1 is from being placed on the user mode schematic diagram under each beam slab joint laterally running through of bridge.Fig. 3 provides is with the station schematic diagram of beam slab top when the neoprene bearing behind the airbag aeration.4 is beam slab among the figure, and 5 is bent cap, and 6 is neoprene bearing, and 7 is bridge floor.
Described air bag 1 can also be several, and referring to Fig. 4, the controllable type valve 2 of each air bag is controlled by a central controller 8.Central controller 8 can be used existing sensors and add the electronic controller that single chip machine controlling circuit constitutes, by sensor the inflated condition of each air bag is passed to single chip machine controlling circuit, control each electromagnetic valve by single chip machine controlling circuit, thereby assurance all keeps synchronous consistent when making each airbag aeration and venting.Fig. 5 provides is a plurality of air bags user mode schematic diagrames under the beam slab joint that vertically is placed on butt joint in twos of bridge respectively.
Claims (4)
1, a kind of device of changing bridge rubber bearing, it is characterized in that described more changing device by air bag, charger and be connected in air bag and charger between the controllable type valve constituted.
