Detailed Description
The following is further detailed by way of specific embodiments: as shown in fig. 1 to 4, the present invention provides a reinforced bridge reinforcing support structure, which is disposed at the bottom of a bridge and includes a base plate 10, a frame 20, an installation plate 30, a reinforcing mechanism 40, a driving mechanism 50, and a pressing member 60.
The frame 20 is fixedly mounted on the base plate 10.
The mounting plate 30 is transversely disposed in the frame 20, and both ends of the mounting plate are fixedly connected to the inner wall of the frame 20. The bottom of the mounting plate 30 is fitted with a motor 53 button 31.
The reinforcing mechanisms 40 have two, and the two reinforcing mechanisms 40 are respectively disposed on both sides of the base plate 10. The reinforcing mechanism 40 includes a limiting plate 41, a tension spring 42, a guide rod 43, a slider 44, a first compression spring 45, and a first wire rope 46. The limiting plate 41 is longitudinally arranged on one side of the bottom plate 10, and the bottom of the limiting plate 41 is hinged with the bottom plate 10. A first end of the tension spring 42 is connected to the stopper plate 41, and a second end of the tension spring 42 is connected to the frame 20. The guide rod 43 is transversely disposed in the frame 20 and located below the mounting plate 30, a first end of the guide rod 43 is fixedly connected to the bottom plate 10, and a second end of the guide rod 43 is fixedly connected to the inner wall of the frame 20. The slider 44 is mounted on the guide bar 43 and is slidably connected to the guide bar 43. The first pressure spring 45 is sleeved on the guide rod 43, a first end of the first pressure spring 45 is connected with the inner wall of the frame body 20, a second end of the first pressure spring 45 is connected with the sliding block 44, and the sliding block 44 has a tendency of being close to the middle of the bottom plate 10 due to the first pressure spring 45. A first end of the first wire rope 46 is connected to the stopper plate 41, and a second end of the first wire rope 46 is connected to the slider 44. When the limit plate 41 is displaced, the slider 44 slides back and forth on the guide rod 43 by the first compression spring 45.
The drive mechanism 50 includes a rotating shaft 51, a drum 52, a motor 53, and two second wire ropes 54. The rotating shaft 51 is disposed in the transverse direction and both ends thereof are rotatably connected to the mounting plate 30. The drum 52 is mounted on the rotating shaft 51. The motor 53 is mounted on the mounting plate 30 for driving the rotating shaft 51 to rotate, and the motor 53 is preferably a motor 53 with a power-off self-locking function, i.e. after power-off, the output shaft of the motor 53 cannot continue to rotate under the action of external force. Two second wire ropes 54 are respectively arranged on two sides of the bottom plate 10, a certain length is reserved in the second wire ropes 54, a first end of each second wire rope 54 is connected with the limiting plate 41 on the same side, and a second end of each second wire rope 54 is connected with the winding drum 52.
And the pressing component 60 is arranged on the slide block 44 and used for pressing the button 31 of the motor 53.
In a normal state, the acting force of the tension spring 42 on the first wire rope 46 is larger than the acting force of the first compression spring 45 on the first wire rope 46. Whether the automobile passes through or the slight earthquake can cause the bridge 80 to slightly shake in the normal range, at the moment, the two tension springs 42 respectively generate tension to the two limiting plates 41, so that the two limiting plates 41 clamp the two sides of the bridge 80, and the primary reinforcing effect is achieved.
When external factors such as an earthquake and the like cause great shaking of the bridge 80, the limiting plate 41 can shift outwards due to shaking and impact of the bridge 80, at the moment, the sliding block 44 can move towards the middle of the bottom plate 10 under the action of the first pressure spring 45, and then the pressing component 60 can press the button 31 of the motor 53. When the motor 53 is powered on to work, the winding drum 52 winds the two second steel wire ropes 54 at the same time, and then under the pulling action of the second steel wire ropes 54, the two limiting plates 41 further clamp the bridge 80 to reinforce the primary reinforcing effect, so that the shaking of the bridge 80 is reduced. The whole structure is simple and convenient to install.
In one embodiment, pressing assembly 60 includes a pressing plate 61 and two connecting rods 62. The pressing plate 61 is disposed right below the button 31 of the motor 53 in the lateral direction, and the two connecting rods 62 are disposed below the pressing plate 61, respectively. The first end of the connecting rod 62 is rotatably connected to the pressing plate 61, and the second end of the connecting rod 62 is rotatably connected to the slider 44 on the same side.
When the sliding block 44 moves towards the middle of the bottom plate 10, the two connecting rods 62 push the pressing plate 61 to move upwards, and further, when the bridge 80 shakes greatly, all the parts can be linked quickly, and the pressing plate 61 can press the button 31 of the motor 53 even.
In one embodiment, the telescopic device further comprises a first telescopic rod 21 arranged in the frame body 20 along the longitudinal direction, the upper end of the first telescopic rod 21 is fixedly connected with the pressing plate 61, and the lower end of the first telescopic rod 21 is fixedly connected with the bottom plate 10. The first telescopic rod 21 plays a role in guiding the movement of the pressing plate 61, so that the upward movement of the pressing plate 61 is more stable.
In one embodiment, the second cable 54 must be reserved for a certain length due to the offset of the retainer plate 41, but this may cause the second cable 54 to be wound with other objects, thereby affecting the operation of the whole support structure.
In order to solve the above problem, the pressing assemblies 70 are disposed on both sides of the base plate 10, and the pressing assemblies 70 are located in the frame 20. Specifically, the compressing assembly 70 includes a second telescopic rod 71, a first guide wheel 72 and a second compression spring 73. The second telescopic rod 71 is disposed along the longitudinal direction, and a first end of the second telescopic rod 71 is fixedly connected to the frame 20 or the mounting plate 30 through a connecting plate 74. The first guide pulley 72 is installed at the second end of the second telescopic rod 71, and the second wire rope 54 is wound around the first guide pulley 72. The second compression spring 73 is sleeved on the second telescopic rod 71, a first end of the second compression spring 73 is connected with the connecting plate 74, and a second end of the second compression spring 73 is connected with the lower end of the second telescopic rod 71. Therefore, the pressing component 70 can keep the second steel wire rope 54 on the same side always tight, and the risk that the second steel wire rope 54 is wound with other objects is avoided.
In one embodiment, there are at least two hold-down assemblies 70 on each side of the base plate 10, and two adjacent hold-down assemblies 70 are mounted to the frame 20 and the mounting plate 30, respectively. Two hold-down assemblies 70 can better increase the reserved length of the second wire rope 54.
In one embodiment, the second guide wheels 11 are installed on both sides of the base plate 10, and the first wire rope 46 is wound around the second guide wheels 11. Due to the design of the second guide wheel 11, the second steel wire rope 54 can be prevented from directly contacting the bottom plate 10, and further, when the limiting plate 41 deviates, abrasion between the second steel wire rope 54 and the bottom plate 10 is avoided.
The above are merely examples of the present invention, and common general knowledge of known specific structures and characteristics in the schemes is not described herein. It should be noted that, for those skilled in the art, without departing from the structure of the present invention, several changes and modifications can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicability of the present invention.
