Description

Technical Field

[0001] The utility model relates to the technical field of bridge construction, in particular to a falling-block preventing block which is easy to position. Background Technique

[0002] When natural disasters such as earthquakes occur, the bridge may be subjected to strong vibrations and impacts, resulting in displacement, inclination or even falling of the beam body, thus endangering the safety and normal use of the bridge. In order to prevent this situation, devices such as falling-block preventing blocks need to be arranged in the bridge structure to increase the seismic resistance of the bridge. Anti-falling beam devices such as bridge seismic blocks, beam-beam, beam-pier tie rods (cables) are important measures for bridges to prevent beam falling in the case of "unexpected seismic loads". The seismic design concept of modern bridges has incorporated ductility design and seismic isolation and vibration reduction design technologies, allowing the bridge to have local damage and large displacements during strong earthquakes. At the same time, it is required to set up "fuse" components to protect the superstructure of the structure from destructive damage under "unexpected seismic loads" and not seriously affect traffic. Bridge blocks and anti-falling beam devices are such "fuse" structures. Publication No.: CN211973070U discloses a falling-block preventing block, which includes a block top plate. Small holes convenient for installation are arranged around the block top plate. Block bending-resistant steel plates perpendicular to the block top plate are arranged at both ends of the block top plate. A block shear-resistant steel plate is arranged between the block bending-resistant steel plates. The block shear-resistant steel plate is perpendicular to both the block top plate and the block bending-resistant steel plates. T-shaped installation grooves are arranged in both the block bending-resistant steel plates and the block shear-resistant steel plates. A pressure buffer assembly is detachably arranged in the T-shaped installation groove through a connecting component. The pressure buffer assembly is detachably connected to both the block shear-resistant steel plate and the block bending-resistant steel plate through a locking component. The utility model realizes the detection of the beam body offset through the elastic deformation of the buffer spring in the pressure buffer assembly. However, for the above-mentioned device, during the use of the device, the device cannot be quickly positioned, the installation of the device is more cumbersome, and at the same time, the working intensity and working time of the staff are increased, which needs to be improved.

Then, the movement of the slider 19 drives the fixed arc block 20 to move. Then, the movement of the slider 19 drives the third spring 18 to be squeezed. Then, one end of the lifting rope is connected to the fixed arc block 20 and then separated from the surface of the pull block 21. Through the rebound movement of the third spring 18, the device can be fixedly connected to the lifting rope. Then, the sliding block 4 is in contact with the surface of the reserved groove, and then the surface of the device is pushed. Subsequently, the movement of the device drives the sliding plate 6 to move towards the outer surface of the device. Then, when the sliding plate 6 moves to be separated from the fixed hole 3, the second spring 12 performs a reset movement. The reset movement of the second spring 12 drives the elastic block 13 to move. Then, the movement of the elastic block 13 drives the limiting rod 14 to move. When the elastic block 13 moves to be in contact with the inner surface of the reserved groove, the device can be positioned. Then, the lifting rope is separated from the fixed arc block 20.
