[0002] Bridge bearings are common supporting components in the field of bridge engineering. They are generally used between upper and lower components to transmit loads downward. The upper component generally refers to the beam, and the lower component refers to the pier. In order to adapt to the translation and rotation of the beam, the bearings generally use tensile ball steel bearings or ordinary ball steel bearings. A sliding body assembly is provided inside the bearing. The sliding body assembly mainly includes sliding friction materials. It is the key for the bearing to adapt to the repeated sliding deformation of the upper structure due to temperature changes, shrinkage creep, dynamic loads, etc. The sliding body assembly is the weakest component in the bearing and is easily damaged during frequent sliding of the bearing. The sliding body assembly in the traditional bearing is an integrated structure with the bearing. When replacement is needed, the bearing can only be taken out and replaced together. This method is time-consuming and labor-intensive, and also requires the closure of the bridge to interrupt traffic, causing traffic jams and a bad social impact. Utility Model Content

[0032] Example 1

[0033] A support that can replace a sliding body in situ includes a support installed between an upper component 26 and a lower component 27. A mounting groove 18 with an opening is provided inside the support. An adaptive sliding body assembly 17 is provided in the mounting groove 18. The sliding body assembly 17 is detachably connected to the support by fasteners. The sliding body assembly 17 includes a fixed plate 6 and a wear-resistant slide 7. The fixed plate 6 is installed in the mounting groove 18. The wear-resistant slide 7 is installed in the groove on the top surface of the fixed plate 6. The sliding body assembly 17 is used to adapt to the relative sliding of the upper component 26 and the support.

[0034] In this embodiment, Figure 1 and Figure 2 As shown, when the sliding body assembly 17 inside the support needs to be replaced, temporary support mechanisms 23 are first installed on both sides of the support. The upper and lower ends of the temporary support mechanism 23 are respectively tightly attached to the bottom surface of the upper component 26 and the top surface of the lower component 27. The upper component 26 is the beam body and the lower component 27 is the pier. Temporary support mechanisms 23 are arranged on both sides of the support to ensure the force balance of the beam body. The temporary support mechanism 23 adopts a hydraulic jack, and then adjusts the force state of the support so that the support no longer feels the load of the upper component 26. At the same time, the temporary support mechanism 23 feels the entire load of the upper component 26 and plays a role of temporary support. Remove the fasteners, and then you can directly take out the sliding body assembly 17 to be replaced from the support along the opening direction of the installation groove 18. The installation groove 18 is open at both ends. The structure is then pushed into the installation groove 18 from the opening of the installation groove 18. After the installation is completed, the fasteners are reassembled and the force state of the support is adjusted again. At this time, it is adjusted to the force state where the support feels the entire load of the upper member 26. At this time, the temporary support mechanism 23 no longer feels the load of the upper member 26, and it is removed to complete the replacement of the sliding body assembly 17. During the entire replacement process, there is no need to take out the support together, and the support will not be moved. The replacement of the sliding body assembly 17 can be achieved in the original position of the support. During the replacement, only the force state of the support needs to be adjusted, which saves time and effort. During the replacement, since there is a temporary support mechanism 23 supporting the beam body, there is no need to close the bridge to interrupt traffic, and basically no social impact or traffic congestion will be caused.

[0035] Furthermore, the support includes an upper seat plate 4, a lower seat plate 5 and a support body 1 located between the upper seat plate 4 and the lower seat plate 5. An upper embedded plate 2 connected to the bottom surface of the upper component 26 is provided above the upper seat plate 4, and a lower embedded plate 3 connected to the top surface of the lower component 27 is provided on the bottom surface of the lower seat plate 5. The sliding body assembly 17 is provided on the top surface of the upper seat plate 4 to adapt to the relative sliding of the upper component 26 and the support, and the adjustment mechanism is provided between the lower seat plate 5 and the bottom surface of the support body 1.

[0036] Further, such as Figure 8 As shown, the sliding body assembly 17 includes a fixed plate 6 and a wear-resistant slide plate 7. The fixed plate 6 is installed on the top surface of the upper seat plate 4, and the wear-resistant slide plate 7 is installed on the top surface of the fixed plate 6. The top surface of the wear-resistant slide plate 7 is in flat contact with the bottom surface of the upper embedded plate 2. The upper seat plate 4 is circumferentially detachably connected with a sealing plate 11.

[0037] Furthermore, the bottom surface of the upper embedded plate 2 is provided with a mounting plate 8 located outside the upper seat plate 4, and the bottom surface of the mounting plate 8 is detachably connected to a tensile plate 9. The side surface of the upper seat plate 4 protrudes outward to form a protrusion 19, and one end of the tensile plate 9 extends to below the protrusion 19.

[0038] Furthermore, the adjustment mechanism includes a driving device 12 and two adjusting blocks 14. The two adjusting blocks 14 are symmetrically distributed between the bottom surface of the support body 1 and the top surface of the lower seat plate 5. The top surface of the adjusting block 14 is in oblique straight contact with the bottom surface of the support body 1, and the bottom surface of the adjusting block 14 is in flat straight contact with the top surface of the lower seat plate 5. The driving device 12 is a hydraulic cylinder and is arranged on both sides of the support body 1 of the adjusting block 14. One end of the driving device 12 is connected to the end of one of the adjusting blocks 14, and the telescopic end of the driving device 12 is connected to the other adjusting block 14.

[0039] In this embodiment, taking the tensile-type ball steel bearing as an example, the bearing includes an upper seat plate 4, a lower seat plate 5 and a rotating body 1 located between the upper seat plate 4 and the lower seat plate 5. The rotating body 1 includes a spherical crown lining plate 101 and an intermediate plate 102. The bottom surface of the spherical crown lining plate 101 and the bottom surface of the intermediate plate 102 are connected by a spherical rotation. This is a conventional setting of the ball steel bearing. The ball steel bearing is an existing bearing, and its translational and rotational functions belong to well-known technologies, which will not be elaborated here. An upper embedded plate 2 connected to the bottom surface of the upper member 26 is provided above the upper seat plate 4, and a lower embedded plate 3 connected to the top surface of the lower member 27 is provided on the bottom surface of the lower seat plate 5. The sliding body assembly 17 is arranged in the mounting groove 18 on the top surface of the upper seat plate 4 to adapt to the relative sliding of the upper member 26 and the support. The adjustment mechanism is arranged between the lower seat plate 5 and the bottom surface of the intermediate plate 102. The upper embedded plate 2 is fixed to the bottom surface of the beam body, and the lower embedded plate 3 is fixed to the top surface of the pier column. The rotating body 1, the lower seat plate 5, and the lower embedded plate 3 are connected. It is fixedly connected to the pier column through the anchor bolt 13. When the height of the support needs to be adjusted, the anchor bolt 13 needs to be removed first. The tensile plate 9 is detachably connected to the bottom end of the fixed plate 6 through the tensile bolt 20. The tensile plate 9 extends toward the side of the upper seat plate 4 to below the protrusion 19. The protrusion 19 and the upper seat plate 4 are integrally formed. An L-shaped assembly groove 16 is formed between the protrusion 19 and the upper seat plate 4. The tensile plate 9 extends into the assembly groove 16, and the tensile plate 9 and the protrusion 19 are assembled in reverse to form a tensile structure. The cam 11 is provided with two fastening bolts 10 on the top, and the fastening bolts 10 on the top connect the cam 11 and the fixing plate 6, and the fastening bolts 10 on the bottom connect the cam 11 and the upper seat plate 4. The wear-resistant slide plate 7 made of polytetrafluoroethylene is provided on the top surface of the fixing plate 6, and the wear-resistant slide plate 7 contacts the flat surface of the upper embedded plate 2. The fixing plate 6 and the wear-resistant slide plate 7 together constitute a sliding body assembly 17. Before replacing the sliding body assembly 17, it is necessary to remove the fastening bolts 10 on both sides of the sealing plate 11 first, and then reinstall it after replacement. The mounting plate 8 on the bottom surface of the upper embedded plate 2 forms a pelvic structure, which can restrict the upper seat plate 4. Since the ball steel bearing has the function of adapting to the rotation of the beam body, the existing ball steel bearing has an integral mounting block 15 on the bottom surface of its upper seat plate 4. The mounting block 15 constitutes a pelvic structure. The upper end of the rotating body 1 is located in the pelvic structure. The bottom surface of the mounting block 15 is connected to the shear block 21 through the shear bolt 22. Outward protrusions 25 are provided on both sides of the rotating body 1. The bottom surface of the protrusion 25 is an inclined surface. One end of the shear block 21 extends under the protrusion 25. The end surface of the shear block 21 located under the protrusion 25 is also an inclined surface. When the rotation amplitude of the beam body is large, the rotating body 1 can break the shear block 21, and the shear block 21 can play a buffering role. Of course, the shear block 21 is not a necessary component and is selectively set according to the area where the bridge is located.

[0040] like Figure 3 As shown, when the sliding body assembly 17 inside the support needs to be replaced, temporary support mechanisms 23 are first installed on both sides of the support. The upper and lower ends of the temporary support mechanisms 23 are respectively in close contact with the bottom surface of the upper component 26 and the top surface of the lower component 27. The upper component 26 is the beam body and the lower component 27 is the pier. The temporary support mechanisms 23 are arranged on both sides of the support to ensure the force balance of the beam body. The temporary support mechanisms 23 use hydraulic jacks, as shown in FIG. Figure 4 and Figure 5 As shown, if there is a tensile plate 9, first remove the tensile plate 9, as shown in Figure 6 As shown, the fastening bolts 10 on the sealing plate 11 are then removed, the sealing plate 11 is removed, and then the anchor bolts 13 between the rotating body 1 and the lower seat plate 5 are removed. Then, the stress state of the support of the adjusting device is adjusted so that the support no longer feels the load of the upper member 26. At the same time, the temporary support mechanism 23 feels the entire load of the upper member 26 and plays a temporary support role. Figure 7 As shown, the telescopic end of the driving device 12 (hydraulic cylinder) is retracted. At this time, the two adjustment blocks 14 are relatively close to each other, and the height of the rotating body 1 will drop, thereby separating the upper seat plate 4 from the upper embedded plate 2, leaving space for the removal of the sliding body assembly 17. Figure 8 As shown, at this time, the sliding body assembly 17 to be replaced can be directly taken out from the upper seat plate 4 along the opening direction of the mounting groove 18, and then the new sliding body assembly 17 can be pushed into the opening of the mounting groove 18. After installation, the sealing plate 11 is assembled, and the sealing plate 11 is connected to the upper seat plate 4 and the fixing plate 6 respectively by two fastening bolts 10, so that the sliding body assembly 17 is fixed in the mounting groove 18, and then the force state of the support is adjusted again by the adjustment mechanism. Specifically, the telescopic end of the driving device 12 is extended, the two adjustment blocks 14 are relatively separated, and the height of the rotating body 1 rises, so that the wear-resistant slide plate 7 contacts the bottom surface of the upper embedded plate 2. At this time, the force state of the support is adjusted to the full load of the upper component 26. In order to ensure accurate adjustment, a sensor 24 can be set between the two adjustment blocks 14. After the rotating body 1 is subjected to vertical load, the wedge-shaped adjustment block 14 converts and produces horizontal squeezing on the sensor 24. The sensor 24 will generate a reading, and the reading can be used to confirm whether the support feels the full vertical load of the beam. At this time, the temporary support mechanism 23 no longer feels the load of the upper component 26, so it is removed to complete the replacement of the sliding body assembly 17. During the entire replacement process, there is no need to remove the support. The sliding body assembly 17 can be replaced at the original position of the support. During the replacement, only the stress state of the support needs to be adjusted, which saves time and effort. During replacement, since there is a temporary support mechanism 23 supporting the beam body, there is no need to close the bridge to interrupt traffic, and basically no social impact or traffic congestion will be caused.

[0041] Example 3

[0042] Furthermore, the support is an ordinary ball steel support, which includes an upper seat plate 4, a lower seat plate 5 and a rotating body 1 located between the upper seat plate 4 and the lower seat plate 5. The rotating body 1 includes a spherical crown lining plate 101 and an intermediate plate 102. The bottom surface of the spherical crown lining plate 101 is rotatably connected to the top surface of the intermediate plate 102. The mounting groove 18 is opened on the top surface of the spherical crown lining plate 101. The mounting groove 18 is U-shaped with one end open or open at both ends. The fastener includes a fastening bolt 10 and a sealing plate 11. The sealing plate 11 is arranged at the opening of the mounting groove 18. The fastening bolt 10 connects the sealing plate 11 with the fixed plate 6 and the spherical crown lining plate 101.

[0043] In this embodiment, Figure 9 and Figure 10As shown, the support adopts an ordinary ball steel support, and the installation groove 18 is opened on the top surface of the ball crown lining 101. The installation groove 18 adopts a structure with two ends open. When the sliding body assembly 17 inside the support needs to be replaced, a temporary support mechanism 23 is first installed on both sides of the support. The upper and lower ends of the temporary support mechanism 23 are respectively closely attached to the bottom surface of the upper member 26 and the top surface of the lower member 27. The upper member 26 is the beam body and the lower member 27 is the pier column. The temporary support mechanism 23 is arranged on both sides of the support to ensure the force balance of the beam body. The temporary support mechanism 23 adopts Hydraulic jack, then remove the fastening bolts 10 on the sealing plate 11, remove the sealing plate 11, and then remove the anchor bolts 13 between the rotating body 1 and the lower seat plate 5, and then adjust the stress state of the support of the device so that the support no longer feels the load of the upper member 26. At the same time, the temporary support mechanism 23 feels the entire load of the upper member 26 and plays a temporary support role. Specifically, the telescopic end of the driving device 12 is retracted. At this time, the two adjustment blocks 14 are relatively close, and the height of the rotating body 1 will drop, so that the upper seat plate 4 and the spherical crown lining plate are 101 is disengaged to leave space for the removal of the sliding body assembly 17. At this time, the sliding body assembly 17 to be replaced can be directly taken out from the upper seat plate 4 along the opening direction of the mounting groove 18, and then the new sliding body assembly 17 can be pushed into the opening of the mounting groove 18. After the installation is completed, the sealing plate 11 is reassembled. The sealing plate 11 is connected to the spherical crown lining plate 101 and the fixing plate 6 respectively through two fastening bolts 10, so that the sliding body assembly 17 is fixed in the mounting groove 18. The force state of the support is adjusted again by the adjustment mechanism, specifically the driving device The telescopic end of the mounting 12 extends, the two adjustment blocks 14 move away from each other, and the height of the rotating body 1 rises, allowing the wear-resistant slide plate 7 to contact the bottom surface of the upper embedded plate 2. At this point, the support is adjusted to a load state in which the support senses the entire load of the upper member 26. To ensure accurate adjustment, a sensor 24 can be installed between the two adjustment blocks 14. When the rotating body 1 is subjected to a vertical load, the wedge-shaped adjustment block 14 shifts and exerts a horizontal pressure on the sensor 24, which generates a reading. This reading can be used to confirm whether the support senses the entire vertical load of the beam. At this point, the temporary support mechanism 23 no longer senses the load of the upper member 26 and can be removed, completing the replacement of the sliding body assembly 17. The entire replacement process does not require the support to be removed; the sliding body assembly 17 can be replaced in its original position. During the replacement, only the force state of the support needs to be adjusted, saving time and effort. Because the temporary support mechanism 23 supports the beam during replacement, there is no need to close the bridge and interrupt traffic, resulting in virtually no social impact or traffic congestion.

Based on the technical essence of the present invention and within the spirit and principles of the present invention, any simple modification, equivalent replacement and improvement of the above embodiment shall still fall within the scope of protection of the technical solution of the present invention.
