Background technique
Urban waterway is often designed as cast-in-place shape due to meet the required Clearance requirement of preventing waterlogging that drains off floodwaters, superstructure
Formula, structure construction need to remove cast-in-place support after the completion, and due to the limitation of bridge headroom, lower section is creek again, Large Construction
Machinery is difficult into dismounting operation, brings biggish trouble to the construction of engineering.
Under above situation, there are mainly two types of conventional method for dismounting: method one is removed using pontoon, and worker stands in pontoon
On bracket is hung onto piecewise transport to designated position again on ship and put well；Method two is set up before cast-in-situ bridge Superstructure Construction
Steel pipe platform in water, in the steel platform both as bracket set up platform and meanwhile as platform is removed, worker station will be propped up in platform
Frame transports to bridge side, is then hung away with crane.But both methods respectively has disadvantage, the former is removed using ship, due to ship
It shakes, constructing operation is inconvenient, and since bracket is from great and be located at korneforos operation, the personal safety of operator cannot be protected
Barrier；The latter increases with respect to the former construction efficiency, but the steel pipe being located in bridge drop shadow spread, due to bridge superstructure
Obstruction, can not directly extract, can only imderwater cutting, steel pipe more than riverbed can recycle, but the steel under being imbedded in riverbed
Pipe can only waste, and required expense is larger, and economic benefit is bad.
Utility model content
In order to overcome the deficiencies of the prior art, the utility model provides a kind of dismounting device of bridge construction bracket, guarantees
The construction safety of striking improves working efficiency, avoids wasting, save the cost.
The technical scheme adopted by the utility model to solve the technical problem is as follows:
A kind of dismounting device of bridge construction bracket, including Screw arbor with nut at both-ends, guide rail, trolley and hand for slinging bracket
Cucurbit is drawn, one end of the Screw arbor with nut at both-ends connects bridge, and the other end connects the guide rail, and the chain block is connected to described small
Che Shang, the trolley are slided along the guide rail, and the bracket is mobile.
Preferably, the trolley includes vehicle frame and bearing, and the bearing is four, and four bearings are one two-by-two respectively
Group is symmetricly set on the two sides of the inside of the vehicle frame.
Preferably, the bearing is arranged on the vehicle frame by round steel, the fixed bearing in one end of the round steel
Middle part, the other end is fixed on the vehicle frame.
Preferably, the bottom end of the trolley is equipped with the connecting plate for connecting the chain block, sets in the middle part of the connecting plate
There is connecting hole.
Preferably, one end that the Screw arbor with nut at both-ends is connect with the bridge passes through the bridge, and is fixed by nut.
Preferably, gasket is equipped between the nut and the bridge.
Preferably, the guide rail is H profile steel.
Preferably, the both ends of the guide rail are equipped with locating part.
The beneficial effects of the utility model are: will first pull calabash when needing to remove bridge construction bracket by setting trolley
Reed is suspended on trolley, then connecting bracket, then trailer wagon along guide rail be moved to bridge edge after by crane for hoisting branch
Frame is the dismounting for realizing bracket, not only ensure that the construction safety of striking, also improves working efficiency.Simultaneously as
Without cutting support, waste is avoided, cost has been saved.The utility model structure is simple, and using effect is good, easy to spread to make
With.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the dismounting device of the bridge construction bracket of the utility model.
Wherein: 1- Screw arbor with nut at both-ends, 2- guide rail, 3- trolley, 31 vehicle frames, 32- bearing, 33- round steel, 4- chain block, 5- bridge
Beam, 6- connecting plate, 61- connecting hole, 7- nut, 8- gasket, 9- locating part.
Specific embodiment
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below
Embodiment is not intended to limit the scope of the present invention for illustrating the utility model.Based on the implementation in the utility model
Example, every other embodiment obtained by those of ordinary skill in the art without making creative efforts belong to
The range of the utility model protection.
Please refer to attached drawing 1, a kind of dismounting device of bridge construction bracket of the present embodiment, including Screw arbor with nut at both-ends 1, guide rail
2, trolley 3 and the chain block 4 for slinging bracket, one end of the Screw arbor with nut at both-ends 1 connect bridge 5, described in other end connection
Guide rail 2, the chain block 4 are connected on the trolley 3, and the trolley 3 is slided along the guide rail 2, and the bracket is mobile.
The dismounting device of bridge construction bracket based on above-mentioned technical characteristic needs to remove bridge by the way that trolley 3 is arranged
First chain block 4 is suspended on trolley 3 when construction bracket, then connecting bracket, then trailer wagon 3 is moved to bridge along guide rail 2
The dismounting for realizing bracket behind 5 edge of beam by crane for hoisting bracket, not only ensure that the construction safety of striking,
It improves work efficiency.Simultaneously as not having to cutting support, waste is avoided, cost has been saved.The utility model structure letter
Single, using effect is good, use easy to spread.
In the present embodiment, the trolley 3 includes vehicle frame 31 and bearing 32, and the bearing 32 is four, four bearings
