Abstract
The utility model belongs to the technical field of be the equipment technique of bridge construction and specifically relates to a device that falls is prevented in bridge construction. It has the connection anchor rope that runs through in bridge inside, the one end of connection anchor rope be provided with fixed turnplate, one side of fixed turnplate is provided with stretch -draw end buffer, fixed turnplate's opposite side is provided with the diverter, one side of stretch -draw end buffer is provided with elastic mechanism and lock nut, the other end of connecting the anchor rope is provided with the stiff end buffer, one side of stiff end buffer is connected with lock nut. After adopting above -mentioned structure, install simple and convenient, through resilient means can be fine the absorption and bear the big displacement volume that huge shock wave caused, can carry out effectual direction to various bending forces through the diverter and alleviate, through effectual absorbed energy of buffer and absorb power, improve the factor of safety of bridge, reduce the loss that the secondary dropped and causes.
Description
Technical field
The utility model relates to the equipment technical field of bridge construction, especially a kind of bridge construction anti-drop device.
Background technology
Bridge, as the multi-purpose project in traffic lines, because natural causes such as earthquakes, can cause the danger that beam destroys.Thus whole traffic system is paralysed state, also can cause great loss to the people's lives and property, cause the significant impact of each side, and after the beam that falls, the repair of bridge also can become complexity extremely.
Bridges in Our Country mainly adopts a girder falling equipment and the devices such as crab-bolt, block, steel bracket at present, does not substantially all arrange the second time anti-fall girder apparatus dropped under bridge macroseism.
In view of the badly damaged property of the beam that falls that bridge causes because of disasters such as earthquakes, necessary device anti-fall girder apparatus being appointed as important beam bridge or earthquake district occurred frequently bridge has been set about in countries and regions a lot of at present.
Utility model content
The technical problems to be solved in the utility model is: in order to solve the prior art Problems existing in above-mentioned background technology, providing a kind of bridge construction anti-drop device, installing simple and convenient, can effectively prevent secondary falling beam, reduce bridge drop produce damage.
The utility model solves the technical scheme that its technical problem adopts: a kind of bridge construction anti-drop device, there is the connection anchor cable through bridge inside, one end of described connection anchor cable is provided with fixing rotating disk, the side of described fixing rotating disk is provided with stretching end snubber, the opposite side of described fixing rotating disk is provided with deflector, and the side of described stretching end snubber is provided with elastic mechanism and locking nut; The other end of described connection anchor cable is provided with fixed end snubber, and the side of described fixed end snubber is connected with locking nut.
Further, in technique scheme, described elastic mechanism is pyramid type spring.When such design can bear earthquake or the big displacement quantity that causes of huge explosion wave rope, also can absorb the lax of steel strand.
Further, in technique scheme, described deflector is fixedly connected on the both sides connecting anchor cable by trip bolt.Such design can be led to the multi-directional bending that earthquake or enormous impact ripple rope cause, alleviate the local buckling stress occurring in connecting strand, make the anchoring position connecting anchor cable can not produce flexural stress and shear stress, reduce to destroy, improve intensity.
Further, in technique scheme, the locking nut at described connection anchor cable two ends divides the distance of taking leave of connection anchor cable head to be 10 ~ 20mm.Such design is the installation handling of conveniently anti-drop device.
The beneficial effects of the utility model are: install simple and convenient, can well absorb and bear by elastic device the big displacement quantity that huge shock wave causes, effectively can be led alleviation to various bending force by deflector, energy is effectively absorbed and the power that withstands shocks by snubber, improve the safety factor of bridge, reduce secondary and to drop the loss caused.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
In figure: 1, connect anchor cable, 2, fixing rotating disk, 3, stretching end snubber, 4, deflector, 5, elastic mechanism, 6, locking nut, 7, fixed end snubber, 8, trip bolt.
Detailed description of the invention
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
A kind of bridge construction anti-drop device as shown in Figure 1, there is the connection anchor cable 1 through bridge inside, the one end connecting anchor cable 1 is provided with fixing rotating disk 2, the side of fixing rotating disk 2 is provided with stretching end snubber 3, the opposite side of fixing rotating disk 2 is provided with deflector 4, the side of stretching end snubber 3 is provided with elastic mechanism 5 and locking nut 6, and the other end connecting anchor cable 1 is provided with fixed end snubber 7, and the side of fixed end snubber 7 is connected with locking nut 6.
Wherein, elastic mechanism 5 is pyramid type spring.Deflector 4 is fixedly connected on the both sides connecting anchor cable 1 by trip bolt 8.It is 10 ~ 20mm that the locking nut 6 points at connection anchor cable 1 two ends takes leave of the distance connecting anchor cable 1 head.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this utility model technological thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on manual, must determine its technical scope according to right.
