Detailed Description
The following is further detailed by way of specific embodiments: as shown in fig. 1 to 7, the present invention provides a bridge reinforcing and anti-girder-dropping integrated structure, which is disposed between a bridge pier 10 and a bridge slab 20, and includes two clamping mechanisms 30, wherein the two clamping mechanisms 30 are respectively disposed on two sides of the bridge slab 20. The top of the pier 10 is provided with a sliding chute 15 extending downwards, the two clamping mechanisms 30 are respectively located at two ends of the sliding chute 15, and each clamping mechanism 30 comprises a bottom plate 31, a longitudinal plate 32, a transverse plate 33, a first spring 34, a guide rail 35, a sliding block 36, a driving rod 37, a rotating shaft 38, a pawl assembly 40 and a first steel wire rope 39.
The bottom plate 31 is disposed in the slide groove 15 and slidably connected to an inner wall of the slide groove 15. The bottom plate 31 is movable in the slide groove 15 in the lateral direction, and a receiving cavity 311 is formed inside the bottom plate 31.
The vertical plate 32 is disposed along the longitudinal direction, and the lower end of the vertical plate 32 is located in the accommodating cavity 311 and is connected with the inner wall of the accommodating cavity 311 in a sliding manner. The longitudinal plate 32 is movable in the longitudinal direction in the receiving cavity 311, and the upper end of the longitudinal plate 32 passes through the bottom plate 31 and then continues to protrude upward. The longitudinal plate 32 has a through groove 321 formed in the middle thereof and extending in the transverse direction.
The transverse plate 33 is transversely disposed directly above the bridge plate body 20 and is fixedly connected to the longitudinal plate 32.
The first spring 34 is longitudinally disposed between the cross plate 33 and the bridge plate 20, and both ends of the first spring are connected to the bridge plate 20 and the cross plate 33. For some earthquakes with lower grades, the first spring 34 can play a role in buffering and energy consumption on one hand, so that part of energy of small earthquakes is consumed, the vibration of the bridge plate body 20 is reduced, and the vibration resistance of the bridge is increased; on the other hand, rigid contact between the bridge plate body 20 and the longitudinal plate 32 can be avoided, and damage caused by rigid contact is reduced.
The guide rail 35 is fixedly mounted on the outer wall of the longitudinal plate 32 in the longitudinal direction. The slider 36 is disposed on the guide rail 35 and slidably connected to the guide rail 35, and the slider 36 is movable on the guide rail 35 in the longitudinal direction. The slider 36 is provided with a limiting groove 361 running through along the transverse direction, and the size of the limiting groove 361 is smaller than that of the through groove 321.
The first end of the driving rod 37 is connected with the bridge plate body 20, the second end of the driving rod 37 transversely penetrates through the through groove 321 and the limiting groove 361 and then extends outwards, and the size of the driving rod 37 is matched with that of the limiting groove 361.
When an earthquake occurs, the propagation speed of longitudinal waves is faster than that of transverse waves, a certain time interval exists between the longitudinal waves and the transverse waves, and the destructive power of the transverse waves to surface buildings is stronger. When an earthquake with a higher grade occurs, the size of the driving rod 37 is matched with that of the limiting rod, and the size of the limiting groove 361 is smaller than that of the through groove 321, so that after longitudinal waves reach the ground, the bridge plate body 20 can vibrate up and down, the driving rod 37 can move up and down in the through groove 321, and the sliding block 36 is driven to slide up and down on the guide rail 35 under the action of the limiting groove 361.
The rotating shaft 38 is fixedly mounted on the outer wall of the longitudinal plate 32 in the transverse direction and is rotatably connected with the longitudinal plate 32. The first reel 381 and the ratchet wheel 382 are fixedly mounted on the rotating shaft 38.
A first end of the first wire rope 39 is connected to the first reel 381, and a second end of the first wire rope 39 passes downward through the bottom plate 31 and then is connected to a lower end of the vertical plate 32.
The slide 36 slides up and down the guide rail 35 to operate the pawl assembly 40. When the pawl assembly 40 works, the ratchet wheel 382 and the rotating shaft 38 are driven to rotate, the rotating shaft 38 drives the first reel 381 to wind the first steel wire rope 39, so that the longitudinal plate 32 and the transverse plate 33 move downwards until the transverse plate 33 presses the top of the bridge plate 20, and at this time, the bridge plate 20 and the pier 10 are temporarily integrated. Therefore, when the transverse wave really arrives, the bridge plate 20 does not greatly shake on the bridge pier 10 because the bridge plate 20 and the bridge pier 10 are integrated, thereby reinforcing and preventing the bridge from falling.
It should be noted that the pawl assembly 40 and the ratchet wheel 382 are matched to have a self-locking function, so that when the ratchet wheel 382 drives the rotating shaft 38 to rotate, the first reel 381 only winds the first steel wire rope 39 more and more tightly, the first steel wire rope 39 is not loosened, and the transverse plate 33 only presses the top of the bridge plate body 20 more and more tightly.
In one embodiment, the pawl assembly 40 includes a first pawl 41, a second pawl 42, and a tension spring 43. The first pawl 41 and the second pawl 42 are respectively disposed on both sides of the ratchet wheel 382. A first end of the first pawl 41 is rotatably coupled to the slider 36 and a second end of the first pawl 41 abuts a first side of the ratchet wheel 382. preferably, the second end of the first pawl 41 is of a conventional pawl configuration. A first end of the second pawl 42 is rotatably coupled to the slider 36 and a second end of the second pawl 42 abuts a second side of the ratchet wheel 382. preferably, the second end of the second pawl 42 is in a hook configuration. A tension spring 43 is disposed in the transverse direction and has both ends connected to the first pawl 41 and the second pawl 42, respectively, and the tension spring 43 makes the first pawl 41 and the second pawl 42 have a tendency to approach each other, so that the first pawl 41 and the second pawl 42 can cooperate with each other.
In this embodiment, the pawl assembly 40 has at least two operating states, in the first operating state, the slider 36 slides up the guide rail 35, the first pawl 41 slides on the ratchet wheel 382, and the hook structure of the second pawl 42 pulls the ratchet wheel 382 to rotate. In the second operating state, the slider 36 slides down on the guide rail 35, the second pawl 42 slides on the ratchet wheel 382, and the first pawl 41 pushes the ratchet wheel 382 to rotate. The cooperation of the first pawl 41 and the second pawl 42 enables the ratchet wheel 382 to drive the rotating shaft 38 and the first reel 381 to rotate in one direction, so as to wind the first cable 39. The up-and-down sliding of the slider 36 on the guide rail 35 is caused by longitudinal waves.
In one embodiment, a second spring 50, a drive mechanism 60, a shock sensor 11, a power source 12, and a controller 13 are also included. The second spring 50 is laterally disposed between the cross plate 33 and the bridge plate 20, and has two ends connected to the bridge plate 20 and the cross plate 33, respectively, and functions similarly to the first spring 34.
The driving mechanism 60 is disposed at a middle portion of the chute 15, and specifically, the driving mechanism 60 includes a motor 61, a rotating lever 62, a worm 63, a worm wheel 64, a second drum 65, and a second wire rope 66. The motor 61 and the rotating rod 62 are both fixedly mounted on the inner wall of the chute 15. A worm 63 is mounted on an output shaft of the motor 61, and a worm wheel 64 is mounted on the rotating lever 62 and engaged with the worm 63. The second reel 65 is mounted on the turning rod 62. The number of the second wire ropes 66 is two, first ends of the two second wire ropes 66 are both connected to the second winding drum 65, second ends of the two second wire ropes 66 are respectively connected to the bottom plates 31 of the two clamping mechanisms 30, and the two second wire ropes 66 can be wound by the second winding drum 65. The vibration sensor 11, the power source 12, and the controller 13 are installed on the pier 10. The controller 13 is electrically connected to the motor 61, the shock sensor 11 and the power source 12.
When an earthquake occurs, the earthquake can cause the vibration of the bridge pier 10, when the vibration detected by the vibration sensor 11 exceeds a safety value, the controller 13 controls the motor 61 to work, the motor 61 drives the worm wheel 64 and the rotating rod 62 to rotate through the worm 63, and the rotating rod 62 drives the second winding cylinder to wind the second steel wire rope 66, so that the longitudinal plate 32 and the transverse plate 33 move along the transverse direction until the longitudinal plate 32 compresses the side wall of the bridge plate body 20. After the longitudinal plates 32 and the transverse plates 33 are tightly pressed on the bridge plate body 20, the integrity between the bridge plate body 20 and the bridge pier 10 is better, the shaking of the bridge plate body 20 on the bridge pier 10 is further reduced, and the reinforcing and anti-beam-falling effects on the bridge are better.
In one embodiment, a torsion spring 383, a first electromagnet 44, and a second electromagnet 45 are also included. The torsion spring 383 is sleeved on the rotating rod 62, a first end of the torsion spring 383 is connected with the outer wall of the longitudinal plate 32, a second end of the torsion spring 383 is connected with the first winding drum 381, and the torsion spring 383 enables the first winding drum 381 to have a reverse rotation trend. The first electromagnet 44 and the second electromagnet 45 are arranged between the first pawl 41 and the second pawl 42, the first electromagnet 44 is fixedly connected with the first pawl 41, the second electromagnet 45 is fixedly connected with the second pawl 42, and the first electromagnet 44 and the second electromagnet 45 are both electrically connected with the controller 13.
When the first electromagnet 44 and the second electromagnet 45 need to be reset after the earthquake is ended, the worker energizes the controller 13 to enable the first electromagnet 44 and the second electromagnet 45 to repel each other, at this time, the first pawl 41 and the second pawl 42 leave the ratchet wheel 382, under the action of the first spring 34 and the torsion spring 383, the first winding drum 381 automatically winds the first steel wire rope 39, and then the controller 13 powers off the first electromagnet 44 and the second electromagnet 45 to complete automatic reset.
In one embodiment, the bottom of the lateral plate 33 is formed with a first receiving groove 331 for receiving the first spring 34, and the inner wall of the longitudinal plate 32 is formed with a second receiving groove 322 for receiving the second spring 50. Thus, when the pawl assembly 40 and the motor 61 are operated, the first spring 34 and the second spring 50 are compressed into the first receiving groove 331 and the second receiving groove 322, so that the transverse plate 33 and the longitudinal plate 32 can be completely pressed against and attached to the top and the side walls of the bridge plate 20, and the bridge can be reinforced and prevented from falling.
In one embodiment, the size of the driving rod 37 is smaller than the size of the limiting groove 361, so that a certain gap exists between the driving rod 37 and the sliding block 36, and an excess space is left, so as to prevent the driving rod 37 from driving the sliding block 36 to slide up and down in an earthquake with a lower grade. Thereby ensuring that only a high level of earthquake will cause operation of the pawl assembly 40.
In one embodiment, a plurality of rubber pads 14 are laid between the bridge slab 20 and the bridge pier 10, so as to reduce the abrasion between the bridge slab 20 and the bridge pier 10 and further enhance the shock resistance of the bridge.
