DETAILED DESCRIPTION
[0023] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.
[0024] like Figure 1 to Figure 4 As shown, an adjustable bridge bearing device includes an upper bearing plate 1, and a lower bearing plate 2 is provided at the bottom of the upper bearing plate 1. A group of pressure sensors 11 are circumferentially fixed to the top of the upper bearing plate 1, and the number of pressure sensors 11 is at least four. The design of the pressure sensor 11 is convenient for real-time detection of the pressure borne by the bearing, and at least four pressure sensors 11 are convenient for detection and comparison of the pressure borne by the bearing at multiple angles. A steel lining plate 3 is provided at the bottom of the upper bearing plate 1, a fixing ring 4 is fixed to the top of the lower bearing plate 2, and an adjustment mechanism 5 is provided inside the lower bearing plate 2.
[0025] The adjustment mechanism 5 includes a pouring hole 51, a connecting hole 52, a circular groove 53 and a distribution groove 54. A pouring hole 51 is provided on one side of the lower support plate 2. The end of the pouring hole 51 away from the connecting hole 52 faces upward, and a plug 12 is provided at the end of the pouring hole 51 away from the connecting hole 52. A wear-resistant plate 13 is provided at the portion where the upper support plate 1 and the steel liner plate 3 are connected. The plug 12 is convenient for sealing the pouring hole 51, and the wear-resistant plate 13 is helpful for reducing friction during rotation. A connecting hole 52 is provided at the end of the pouring hole 51, and a circular groove 53 is provided at the top of the connecting hole 52, and the circular groove 53 is located in the middle of the top of the lower support plate 2. A group of distribution grooves 54 are circumferentially provided at the top of the lower support plate 2, and the distribution grooves 54 are all connected to the circular groove 53. A set of sealing rings 14 are fixed to the bottom end of the outer side of the steel liner 3, and a sealing plate 15 is fixed to the bottom end of the steel liner 3. The design of the sealing ring 14 and the sealing plate 15 prevents the slurry from seeping into the gap between the steel liner 3 and the movable ring 61 when filling the slurry.
[0026] When the height needs to be adjusted, the pouring pipe is used to pour the slurry under high pressure. The slurry enters the pouring hole 51, flows into the connecting hole 52, and then enters the circular groove 53. At this time, the slurry will flow evenly to each distribution groove 54, fill the distribution groove 54, and then gradually prop up the steel lining plate 3 and the upper support plate 1 to achieve height adjustment. Furthermore, the device sets a plurality of distribution grooves 54, so that the slurry can flow evenly to each distribution groove 54, so that after the height of the support is adjusted, the force degree at each position is uniform, and there will be no local force unevenness.
[0027] A detection mechanism 6 is provided in the fixed ring 4, and the detection mechanism 6 includes a movable ring 61, an active cavity 62, a displacement sensor 63, a detection slot 64, a battery box 65 and a wireless signal transmitter 66. A movable ring 61 is provided on the top of the lower support plate 2, and the movable ring 61 is located on the inner side of the fixed ring 4. The part between the fixed ring 4 and the movable ring 61 is provided with an active cavity 62. A displacement sensor 63 is fixedly connected to one side of the movable ring 61. A detection slot 64 is provided at the top of the front side of the steel lining plate 3. A battery box 65 and a wireless signal transmitter 66 are respectively fixedly connected in the detection slot 64. A group of springs 7 are fixedly connected to both sides of the movable ring 61, and the other ends of the springs 7 are fixedly connected to the fixed ring 4. Dampers 8 are fixedly connected to both ends of the inner side of the fixed ring 4. The design of the springs 7 and the dampers 8 buffers the deformation of the support. A set of limiting shafts 9 are fixedly connected on both sides of the movable ring 61, and buffer pads 10 are fixedly connected to the ends of the limiting shafts 9. The design of the limiting shafts 9 further limits the movable space of the support deformation so that it will not undergo a large deformation. The buffer pads 10 protect against collisions generated during the deformation process.
[0028] During operation, when an earthquake or other vibration occurs, causing the bridge to move, the design of the movable cavity 62 allows the upper support plate 1 and the steel lining plate 3 to have a certain deformation space, and the movable ring 61 moves in the movable cavity 62. The displacement sensor 63 can detect the moving distance of the upper support plate 1 and the steel lining plate 3 in real time, and send a signal to the wireless signal transmitter 66. The wireless signal transmitter 66 transmits the received signal, which is beneficial for the staff to receive the status and position data of the support in the first time, and is convenient for the staff to maintain.
[0029] Working principle: When the height needs to be adjusted, the pouring pipe is used to pour the slurry under high pressure. The slurry enters the pouring hole 51, flows into the connecting hole 52, and then enters the circular groove 53. At this time, the slurry will flow evenly to each distribution groove 54, fill the distribution groove 54, and then gradually prop up the steel lining plate 3 and the upper support plate 1 to achieve height adjustment. In addition, the device sets a plurality of distribution grooves 54, so that the slurry can flow evenly to each distribution groove 54, so that after the height of the support is adjusted, the force degree at each position is uniform, and there will be no local force unevenness.
[0030] When an earthquake or other vibration occurs, causing the bridge to move, the design of the movable cavity 62 allows the upper support plate 1 and the steel lining plate 3 to have a certain deformation space. The movable ring 61 moves in the movable cavity 62, and the displacement sensor 63 can detect the movement distance of the upper support plate 1 and the steel lining plate 3 in real time, and send a signal to the wireless signal transmitter 66. The wireless signal transmitter 66 transmits the received signal, which is beneficial for the staff to receive the status and position data of the support in the first time, which is convenient for the staff to maintain.
[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
