[0036] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are some embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings herein can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed present application, but only represents selected embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative labor are within the scope of protection of the present application.

[0037] It should be noted that: similar labels and letters represent similar items in the following drawings, therefore, once an item is defined in one drawing, it does not need to be further defined and explained in the subsequent drawings. Meanwhile, in the description of the present application, the terms “first”, “second” and the like are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0038] As Figures 1-5 shown, the present embodiment provides a support assembly, comprising: a lower seat plate 100, which is a mounting base of the present application, to mount other components on the support assembly, usually installed at the position of a bridge pier.

[0039] An upper seat plate 200 is movably arranged on the lower seat plate 100 and sequentially arranged with the lower seat plate 100 in a first direction. The upper seat plate 200 is usually used to bear the beam body, and it can be understood that the first direction can be understood as the direction of gravity when the support assembly is installed on the bridge. The movable design of the upper seat plate 200 can achieve buffering and energy absorption at the epicenter, thereby protecting the bridge.

[0040] A fixing member 300 is connected to the lower seat plate 100. The fixing member 300 is a mounting base for the movable stop member 400 and the driving member described below.

[0041] A movable stop member 400 is movably arranged on the lower seat plate 100 and arranged on the same side of the fixing member 300 on the lower seat plate 100. The movable stop member 400 is used to stop and cooperate with the upper seat plate 200 to constrain the freedom of the upper seat plate 200. In this way, under normal working conditions, the position of the upper seat plate 200 can be fixed by stop cooperation to avoid shaking, thereby ensuring the normal work of the bridge.

[0042] A driving member is connected to the fixing member 300 by driving the movable stop member 400. The driving member can provide the driving force required for the movement of the movable stop member 400, so that the driving member can drive the movable stop member 400 to adjust the movement.

[0043] In the present application, the movable stop member 400, the fixing member 300 and the driving member can be regarded as an adjustment driving mechanism. Through the power provided by the driving member, the relative position between the movable stop member 400 and the fixing member 300 is changed, thereby making the support assembly have an adjustable function. The adjustment principle of the support assembly and the effect achieved by the adjustment are described as follows:

[0044] The fixing member 300, the movable stop member 400 and the upper seat plate 200 can be sequentially arranged along a second direction Y, wherein the second direction Y intersects the first direction X. The second direction Y can be understood as the thickness direction of the fixing member 300 and / or the movable stop member 400, and can also be understood as the horizontal transverse direction.

[0045] As described above, the support assembly is usually installed on the bridge, wherein the upper seat plate 200 is used to connect the beam body, and the lower seat plate 100 is used to connect the bridge pier. Under normal circumstances, the movable stop member 400 will keep the stop cooperation with the upper seat plate 200 to limit the movement of the upper seat plate 200, so that it is fixed at the current position to avoid shaking, thereby ensuring the normal use of the bridge.

[0046] When the bridge is subjected to impact load such as earthquake, the bridge as a whole shakes, and then under the force transmission, the upper seat plate 200 extrudes and impacts the movable stop piece 400, causing the connecting bolt 110 and the shear pin shaft 120 to be sheared off, the beam body and the upper seat plate 200 to be displaced in translation and angular deviation, and the movable stop piece 400 and the fixed piece 300 to fail to stop the upper seat plate 200, so that the upper seat plate 200 and the lower seat plate 100 are relatively moved as shown in the following. Figure 5

[0047] Due to the displacement of the beam body and the upper seat plate 200, it is necessary to reset after the earthquake and restore the stop cooperation between the movable stop piece 400 and the upper seat plate 200 to fix the upper seat plate 200.

[0048] Specifically, after reinstalling the connecting bolt 110 and the shear pin shaft 120, the driving piece can be started to drive the movable stop piece 400 to adjust the movement, so that the movable stop piece 400 is again stopped and cooperated with the upper seat plate 200 under the force transmission to fix and position constrain the upper seat plate 200, ensuring the subsequent use of the bridge.

[0049] It can be seen that the adjustable design of the fixed piece 300, the movable stop piece 400 and the driving piece enables the support assembly to have an adjustable function and to realize the repair of the constraint relationship of the support assembly after the earthquake, so that the support assembly does not need to be replaced and maintained as a whole, and the bridge can be quickly restored to work after the earthquake, greatly reducing the operation and maintenance cost of the bridge.

[0050] It should be noted that the stop cooperation of the movable stop piece 400 with the upper seat plate 200 is that a small gap is kept between the movable stop piece 400 and the upper seat plate 200, and the gap value is between 0.5mm and 1mm. This is because in normal use, considering the factors such as the vehicle driving on the bridge and thermal expansion and contraction, there needs to be a certain relative movement amplitude between the upper seat plate 200 and the lower seat plate 100 to make the bridge have a certain flexibility, so that in normal working conditions, the bridge can resist the impact load and deformation, and at the same time, the relative position between the upper seat plate 200 and the lower seat plate 100 can be controlled within the allowable range, so as to comprehensively ensure the reliable operation of the bridge.

[0051] Optionally, the support assembly can further include the connecting bolt 110 and the shear pin shaft 120, one end of the shear pin shaft 120 is inserted into the lower seat plate 100, the other end of the shear pin shaft 120 is inserted into the fixed piece 300 and is positioned and cooperated with the fixed piece 300. The fixed piece 300 is connected with the lower seat plate 100 through the connecting bolt 110.

[0052] ​The reason for selecting the shear pin 120 is that the shear capacity of the shear pin 120 can be improved. Specifically, in normal working conditions or small earthquakes, the impact load can be resisted without deformation, thereby achieving the fixation of the fixing member 300, and ultimately ensuring that the movable stop member 400 stably and reliably stops the upper seat plate 200. In other words, in normal working conditions or small earthquakes, the shear capacity of the shear pin 120 can ensure that the support assembly structure is stable and does not change, thereby maintaining the normal operation of the bridge.

[0053] When a large earthquake occurs, the large impact force brought by the earthquake will cause the connecting bolt 110 and the shear pin 120 to suffer shear force, and the connecting bolt 110 and the shear pin 120 can be sheared or cut, thereby protecting the fixing member 300 and the movable stop member 400 from being damaged. Then, in the post-earthquake repair work, the relevant connecting bolt 110 and shear pin 120 can be replaced, without the need to replace the entire support assembly, which more effectively reduces the operation and maintenance cost of the support assembly.

[0054] It should also be noted that the connecting bolt 110 and the shear pin 120 not only serve to fix and position the fixing member 300, but also serve as a kind of fuse, that is, when the earthquake reaches a certain level and the impact load on the support assembly exceeds the tolerance range, the connecting bolt 110 and the shear pin 120 will be deformed or cut to protect other components of the support assembly from being damaged, thereby reducing the operation and maintenance cost of the support assembly.

[0055] Optionally, for the structure of the driving member, an electric push rod, a piston, or other driving mechanisms can be selected to drive the movable stop member 400. To simplify the design and ensure reliable movement, the driving member can include an adjustable screw 500 and an adjusting wheel 600.

[0056] Specifically, the adjusting wheel 600 is rotatably arranged on the fixing member 300, and the adjusting wheel 600 is provided with a threaded hole, the hole axis of the threaded hole is consistent with the second direction Y, and the rotation direction of the adjusting wheel 600 is around the second direction Y.

[0057] The adjustable screw 500 is movably arranged in the fixing member 300, the adjustable screw 500 is connected to the movable stop member 400, and is threadedly connected to the adjusting wheel 600. It can be understood that the length direction of the adjustable screw 500 is consistent with the second direction Y.

[0058] The fixing member 300 can drive the movable stop member 400 through the adjustable screw 500 and the adjusting wheel 600. In the position repair work after the earthquake, the adjusting wheel 600 will generate a spiral driving effect on the adjustable screw 500 when the adjusting wheel 600 is rotated, so that the adjustable screw 500 can move towards the second direction Y to drive the movable stop member 400 to perform an adjusting movement, and then the movable stop member 400 re-implements the stop cooperation with the upper seat plate 200.

[0059] Optionally, for the specific structure of the adjusting wheel 600, the adjusting wheel 600 can be provided in the form of a roller structure, but in order to facilitate use, the adjusting wheel 600 in the present application can be selected as a nut, such as an outer hexagonal nut, so that it is convenient to obtain materials, and the torque of the adjusting wheel 600 can be increased by adding a torque wrench or the like to the adjusting wheel 600 to realize the rotation of the adjusting wheel 600, so that the movable stop member 400 can transmit greater driving force, and the adjusting movement of the movable stop member 400 can be more conveniently and effectively realized.

[0060] Optionally, the support assembly can also be provided with a gasket 610, which can be sleeved on the adjustable screw 500 and located between the adjusting wheel 600 and the fixing member 300. The design of the gasket 610 can avoid direct contact between the adjusting wheel 600 and the fixing member 300 to cause wear, and in the case of using a spring washer as the gasket 610, the gasket 610 can also play a role in preventing loosening to prevent the adjusting wheel 600 from loosening and moving.

[0061] Optionally, the fixing member 300 can be provided with a through hole, and the adjustable screw 500 can be movably arranged in the through hole in a clearance fit. The clearance fit formed by the reserved gap can make the movement process of the adjustable screw 500 not be disturbed by friction, so as to ensure that the adjusting movement is more smooth, and the support assembly can more effectively and conveniently realize the position repair.

[0062] Optionally, the fixing member 300, the movable stop member 400, the adjustable screw 500 and the adjusting wheel 600 in the present application can form an adjusting mechanism. The adjusting mechanism can be symmetrically arranged on both sides of the upper seat plate 200 towards the second direction Y, so that the movable stop member 400 cooperates with the upper seat plate 200 to stop.

[0063] As can be seen, the adjusting mechanism is arranged on both sides, so that the movable stop member 400 can constrain the position of both sides of the upper seat plate 200, and the position of the upper seat plate 200 can be more effectively and stably limited. Of course, in the position repair work after the earthquake, the movable stop members 400 on both sides need to perform adaptive adjusting movements to re-implement the stop of the upper seat plate 200, which will not be described here.

[0064] Of course, the adjusting mechanism composed of the fixed part 300, the movable stop part 400, the adjustable screw 500 and the adjusting wheel 600 can also be provided on only one side of the movable stop part 400, which will not be described in detail here.

[0065] Optionally, the adjustable screw 500 and the adjusting wheel 600 can be provided in multiple numbers. Specifically, the adjustable screw 500 and the adjusting wheel 600 are grouped one-to-one, and multiple groups of the adjustable screw 500 and the adjusting wheel 600 are provided in the third direction Z.

[0066] Wherein, the third direction Z, the first direction X and the second direction Y intersect with each other. The third direction Z can be understood as the length direction of the fixed part 300 or the movable stop part 400. The design of multiple adjustable screws 500 and multiple adjusting wheels 600 can enrich the adjustment movement mode of the movable stop part 400, and the specific principle is as follows:

[0067] When an earthquake occurs, the movement mode of the upper seat plate 200 relative to the lower seat plate 100 is complex, which is a combination of multiple different movements. For example, the upper seat plate 200 can appear to be translated relative to the lower seat plate 100, or can appear to be angularly offset relative to the lower seat plate 100. Then, in order to adapt to the complex and variable movement mode of the upper seat plate 200 in the epicenter, the movable stop part 400 should also have multiple movement modes to adapt.

[0068] Specifically, in the case that the distance of movement of each adjustable screw 500 in the second direction Y is consistent, the movable stop part 400 performs a translational adjustment movement, such as shown in FIG. 6A. Figure 3 And in the case that the distance of movement of at least two adjustable screws 500 in the second direction Y is inconsistent, the movable stop part 400 performs an angular adjustment movement, such as shown in FIG. 6B. Figure 4

[0069] As can be seen, the adjustment movement includes a translational adjustment movement and an angular adjustment movement; wherein the movement plane of the angular adjustment movement and the movement plane of the translational adjustment movement are both parallel to the second direction Y and parallel to the third direction Z.

[0070] In this way, after an earthquake, through the translational adjustment movement of the movable stop part 400, the impact caused by the translational movement of the upper seat plate 200 in the earthquake can be repaired. And through the angular adjustment movement of the movable stop part 400, the impact caused by the angular offset movement of the upper seat plate 200 in the earthquake can be repaired. More effectively, the movable stop part 400 and the upper seat plate 200 are restored to stop cooperation.

[0071] ​Optionally, the adjustable screw 500 and the adjusting wheel 600 are arranged in three in the third direction Z, and the adjustable screw 500 is arranged at both ends and the middle of the movable stopper 400. In this way, the translational adjustment movement and the angular adjustment movement can be ensured to be effective, especially the effectiveness of the angular adjustment movement, for example, the adjustable screw 500 at one end of the movable stopper 400 moves 5 cm, the adjustable screw 500 at the middle of the movable stopper 400 moves 3 cm, and the adjustable screw 500 at the other end of the movable stopper 400 is fixed, at this time, the movable stopper 400 performs angular offset movement, if the movement distances of the three adjustable screws 500 are consistent, the movable stopper 400 performs translational movement, which will not be described here.

[0072] Optionally, for the specific structure of the fixed part 300 and the movable stopper 400, the fixed part 300 and the movable stopper 400 can be arranged as a baffle structure, so that the third direction Z can be understood as the length direction of the movable stopper 400, and the second direction Y can be understood as the thickness direction of the movable stopper 400. Generally, in order to better realize the adjustment movement of the movable stopper 400, the thickness of the movable stopper 400 can be much smaller than the length of the movable stopper 400, for example, the length to thickness ratio of the movable stopper 400 is between 20 and 24. The thinner thickness facilitates the adjustment movement of the movable stopper 400 after the earthquake, and the longer length of the movable stopper 400 can more effectively realize the stop cooperation with the upper seat plate 200.

[0073] In some embodiments, the support assembly can further include a pad 700 for filling the gap between the fixed part 300 and the movable stopper 400. The use of the pad 700 is as follows:

[0074] As described above, after the earthquake, the adjusting wheel 600 and the adjustable screw 500 can be used to drive the movable stopper 400 to perform adjustment movement until the movable stopper 400 and the upper seat plate 200 restore the stop cooperation. At this time, the driving force of the adjusting wheel 600 and the adjustable screw 500 to the movable stopper 400 keeps the movable stopper 400 and the fixed part 300 relatively fixed, so that the movable stopper 400 performs stop cooperation with the upper seat plate 200 to keep the position of the upper seat plate 200 fixed.

[0075] Subsequently, the pad 700 can be filled in the gap between the movable stopper 400 and the fixed part 300, and after the filling is completed, the movable stopper 400, the filled pad 700 and the fixed part 300 are kept relatively fixed. For example, by welding or bolting the filled pad 700 to the movable stopper 400 and the fixed part 300 respectively, the relative fixation of the three is realized.

[0076] Then the adjusting wheel 600 is loosened, at this time, since the movable stopper 400, the filling pad 700 and the fixed part 300 keep relative fixation, the movable stopper 400 will keep stopper cooperation with the upper seat plate 200, and then the position constraint of the upper seat plate 200 is realized.

[0077] It can be seen that after the filling pad 700 is added, the movable stopper 400 can keep the position fixation between the filling pad 700 and the fixed part 300, and can no longer keep the position fixation between the filling pad 700 and the fixed part 300 through the adjusting wheel 600 and the adjustable screw 500, so that the adjusting wheel 600 and the adjustable screw 500 can be released, so as to protect the service life of the adjusting wheel 600 and the adjustable screw 500.

[0078] Optionally, the pad 700 can include filling pads. The number of filling pads in the pad 700 can be proportional to the size of the gap between the fixed part 300 and the movable stopper 400. Specifically, the larger the gap between the fixed part 300 and the movable stopper 400, the more filling pads need to be added, and the thicker the pad 700, and vice versa. The setting mode of the pad 700 including the filling pads can simplify the structure of the pad 700, and is convenient to use and operate.

[0079] Optionally, the filling pads can be a series of stainless steel plates of different specifications and thicknesses, so as to better adapt to the needs of different gaps.

[0080] Optionally, the support assembly can further include a middle seat plate 800. The middle seat plate 800 is movably supported between the lower seat plate 100 and the upper seat plate 200. The side of the middle seat plate 800 facing the upper seat plate 200 is provided with a first arc surface, the first arc surface protrudes towards the upper seat plate 200, the side of the upper seat plate 200 facing the middle seat plate 800 is provided with a second arc surface, the second arc surface matches the first arc surface and is in close contact with each other. And / or, the side of the middle seat plate 800 facing the lower seat plate 100 is provided with a third arc surface, the third arc surface protrudes towards the lower seat plate 100, the side of the lower seat plate 100 facing the middle seat plate 800 is provided with a fourth arc surface, the fourth arc surface matches the third arc surface and is in close contact with each other.

[0081] It can be seen that the structure formed by the lower seat plate 100, the upper seat plate 200 and the middle seat plate 800 can realize the pendulum reset when subjected to an earthquake. Specifically, when subjected to an earthquake to cause the bridge to be subjected to impact load and other abnormal conditions, through the design of the arc surface, the upper seat plate 200 can more easily realize the shaking relative to the lower seat plate 100, so as to more effectively realize the buffering and energy absorption, and after the earthquake, the design of the arc surface has the automatic centering function similar to the pendulum, and the support assembly can be more easily reset.

[0082] The pendulum reset design reduces the stroke required for the adjustment movement of the movable stop 400, greatly reducing the labor intensity required for the adjustment movement of the movable stop 400.

[0083] Optionally, an adjustable gap 810 can be formed between the lower seat plate 100 and the upper seat plate 200, so that the upper seat plate 200 can move relative to the lower seat plate 100 without interference, and better achieve the shock buffer energy absorption.

[0084] Optionally, the movable stop 400, the adjustable gap 810, and the middle seat plate 800 can be arranged in sequence along the second direction Y, so that the movable stop 400 seals the adjustable gap. In this way, it can prevent dust, accumulated water, and other stains from entering the cavity formed between the lower seat plate 100 and the upper seat plate 200 through the adjustable gap 810, preventing damage to the middle seat plate 800 and the like.

[0085] In some embodiments, the application also discloses a method for using the support assembly, specifically as follows:

[0086] Obtain position adjustment data of the upper seat plate 200 relative to the lower seat plate 100 when the position of the upper seat plate 200 changes.

[0087] Based on the position adjustment data, drive the movable stop 400 to perform an adjustment movement.

[0088] When the movable stop 400 moves to stop cooperating with the upper seat plate 200, stop the adjustment movement.

[0089] Using the above method, the adjustment and position repair of the support assembly can be achieved.

[0090] Optionally, in the case where the driving member includes the adjustable screw 500 and the adjustment wheel 600 described above, the method for using the support assembly is specifically as follows:

[0091] Obtain position adjustment data of the upper seat plate 200 relative to the lower seat plate 100 when the position of the upper seat plate 200 changes. Since the upper seat plate 200 at the epicenter may appear a combination of various movement modes such as translation or angular offset, the position adjustment data here can include translation adjustment data and angular adjustment data.

[0092] Loosen the adjustment wheel 600 to remove the gasket 700 located between the fixed member 300 and the movable stop 400. The position of the movable stop 400 will change after the earthquake, and the size of the gap between the movable stop 400 and the fixed member 300 will also change, so the previous gasket 700 needs to be removed to replace the gasket 700 that is suitable for the size of the gap after the earthquake.

[0093] In the case that the acquired position adjustment data is translation adjustment data, each adjustable screw 500 moves towards the second direction Y, and the movement distance of each adjustable screw 500 is consistent, so that the movable stopper 400 performs a translation adjustment movement. The translation adjustment movement of the movable stopper 400 can adapt to the translation movement of the upper seat plate 200 at the epicenter, so as to re-stop cooperate with the upper seat plate 200, as shown in detail in Figure 3

[0094] In the case that the acquired position adjustment data is angle adjustment data, the distance that at least two adjustable screws 500 move towards the second direction Y is inconsistent, so that the movable stopper 400 performs an angle adjustment movement. The angle adjustment movement of the movable stopper 400 can adapt to the angle offset movement of the upper seat plate 200 at the epicenter, so as to re-stop cooperate with the upper seat plate 200, as shown in detail in Figure 4

[0095] When the movable stopper 400 moves to stop cooperate with the upper seat plate 200, the adjustment movement is stopped, and at this time, through the re-established stop cooperation relationship, the movable stopper 400 will again realize the position constraint and fixation of the upper seat plate 200.

[0096] After the support assembly is reset, the filler block 700 is filled between the fixed part 300 and the movable stopper 400 again. The filling method is as follows: according to the size of the gap between the fixed part 300 and the movable stopper 400 at this time, the filler block 700 is filled into the gap to form a filler block 700 until the gap is filled, so that the movable stopper 400, the filler block 700 and the fixed part 300 are relatively fixed. For example, the filler block 700 is welded or bolted to the movable stopper 400 and the fixed part 300.

[0097] At this time, since the movable stopper 400 has been kept relatively fixed with the fixed part 300 through the filler block 700, the movable stopper 400 is no longer kept relatively fixed with the fixed part 300 through the adjusting wheel 600 and the adjustable screw 500, so the adjusting wheel 600 can be loosened, and the adjusting wheel 600 and the adjustable screw 500 are released, thereby improving the service life of the adjusting wheel 600 and the adjustable screw 500.

[0098] In some embodiments, the application also discloses a bridge, comprising a beam body, a pier and a support assembly. The beam body, the support assembly and the pier are sequentially arranged towards the first direction X, which can be understood as the direction of gravity; the beam body is connected to the upper seat plate 200, and the pier is connected to the lower seat plate 100.

[0099] ​​When affected by impact load such as earthquake, the appearance usually shows the sway between the beam body and the pier, and the sway between the upper seat plate 200 and the lower seat plate 100 is caused by the force transmission, so as to reduce the shock and energy, and protect the safety of the bridge.

[0100] After the earthquake, the movable stopper 400 is adjusted to move, and then the movable stopper 400 and the upper seat plate 200 reestablish the stop cooperation relationship, so as to fix and position the upper seat plate 200 again. In this design, the whole support assembly does not need to be replaced, which greatly saves the operation and maintenance cost.

For those skilled in the art, the present application can have various changes and variations. Any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application should be included in the protection scope of the present application.
