Description

Technical Field

[0001] The present invention relates to the technical field of bridge bearing height adjustment, and in particular to an integrated height adjustment bearing and method. Background Art

[0002] In the existing technology, bridge bearings are divided into ordinary bearings and functional bearings. Functional bearings have shock absorption and energy dissipation functions, while ordinary bearings mainly have simple supporting capabilities. For ordinary bearings, the height of the ordinary bearings needs to be adjusted according to the elevation of the bridge main beam and the pier top. For example, Chinese patent application with publication number CN107447652A discloses a spherical bearing with an adjustable height, which consists of a bearing body system, a bridge deck height monitoring system, a height adjustment system and a control system. The bridge deck height monitoring system is connected to the control system, and the control system controls the height adjustment system to adjust the bridge deck height raised by the bearing body system. The height adjustment system is arranged below the bearing body system and consists of a stepped block, a wedge block, a plurality of vertical pushing devices arranged on the lower surface of the corresponding lower seat plate, a horizontal pushing device connected to the wedge block, and a base plate. When the bridge deck height monitored by the bridge deck height monitoring system reaches the required height adjustment, the vertical height adjustment amount of the bearing is first set, then the control system and the vertical pushing device are started to lift the lower seat plate to a preset height, and then the horizontal pushing device is started to adjust the wedge block to a set horizontal position so that the stepped block falls completely onto the wedge block. Then the vertical force of the vertical pushing device of the control system is unloaded, and the vertical height adjustment of the bearing is completed. Among them, a guide device is provided between the support body system and the base plate, and the support body system moves up and down in the vertical direction through the guide device. The guide device adopts the form of a guide column and a guide groove. The guide column is a cylinder, one end of which is fixedly connected to the base plate, and the other end is inserted into the guide groove. No matter how the height of the step block changes, one end of the guide column is always in the guide groove, which plays the role of transmitting the horizontal force of the support and has good horizontal stiffness.

[0003] The above-mentioned technical solution for adjusting the height of the spherical bearing has the following disadvantages: (1) Considering the effects of manufacturing accuracy, on-site temperature, dust, rust, etc., the guide groove is about 3 mm larger than the guide column diameter. This results in relative displacement between the lower seat plate and the base plate under normal construction conditions, especially under live load, which has an adverse effect on the formation of high-speed railways. (2) There are two wedge blocks, which are symmetrically arranged on both sides of the longitudinal bridge, which affects its vertical bearing capacity. Moreover, the wedge blocks on both sides of the longitudinal bridge are used for height adjustment, so that under the same height adjustment capacity, the overall structure of the support will be larger and higher, which is not conducive to use. (3) The control system and the vertical jacking device are started to lift the lower seat plate to the preset height (slightly higher by 1mm), and then the horizontal jacking device is started to adjust the wedge block to the set horizontal position. Then the vertical jack in the vertical jacking device of the control system is controlled to perform the jacking and lowering operation so that the step block falls completely onto the wedge block. However, it is difficult to judge whether to adjust the wedge block to the set horizontal position during actual construction, which may lead to the horizontal position being not adjusted in place, and the wedge block does not support the step block well, affecting the vertical support capacity. Summary of the Invention

[0004] The purpose of the present invention is to overcome the shortcomings of the prior art in which ordinary supports are adjusted in height using guide columns for guidance in guide grooves.

[0037] The top of the height-adjustable upper seat plate 4 is anchored to the bottom of the standard finished product support 1; and Figure 5 As shown, the central longitudinal cross-section of the top plate 41 is a downward-facing isosceles trapezoid. Upper anchor bolts 2 securely connect the top of the adjustable upper base plate 4 to the bottom of the standard finished support 1, facilitating the anchoring of the top of the fixed step block 5 to the bottom of the adjustable upper base plate 4 via fixing screws 3. The upper anchor bolts 2 and fixing screws 3 are symmetrically arranged in the longitudinal direction, facilitating balanced force distribution. In this embodiment, the top of the fixed step block 5 is anchored to the center bottom of the adjustable upper base plate 4, enhancing vertical support capacity.

The top of the movable step block 6 is supported on the bottom of the fixed step block 5, so that the fixed step block 5 and the step surface of the movable step block 6 are tightly engaged with each other to ensure the stability of the vertical support and realize vertical load-bearing; the inverted step-like structure 51 at the bottom of the fixed step block 5 is adapted to the positive step-like structure 61 at the top of the movable step block 6. Specifically, the inverted step-like structure 51 and the positive step-like structure 61 are both continuous stepped structures, and the steps are vertical steps. Each step includes alternating vertical and horizontal surfaces, and from Figure 5 As can be seen from the figure, the length of the positive step structure 61 is greater than that of the inverted step structure 51, and the inverted step structure 51 can be used at different positions of the positive step structure 61 to achieve the change in height of the inverted step structure 51, thereby changing the height of the fixed step block 5. The sizes of the inverted step structure 51 and the positive step structure 61 are adapted. The length direction of the inverted step structure 51 and the positive step structure 61 is the same, which can be in the horizontal bridge direction or the vertical bridge direction.

[0040] The top of the height-adjustable lower seat plate 8 is supported below the movable step block 6, and the top of the height-adjustable lower seat plate 8 can be used to provide force for the movable step block 6. The bottom of the height-adjustable lower seat plate 8 is used to anchor to the bridge pier; Figure 5 As shown, several anchor bolt assemblies 9 can be used to anchor the bottom of the raised lower seat plate 8 to the supporting pad stone or the top surface of the pier, using the pier top to provide force. Among them, the arrangement of the anchor bolt assemblies 9 also adopts a symmetrical arrangement form to make the force more balanced.

[0041] In an optional embodiment, a second polytetrafluoroethylene slide 14 is provided between the movable step block 6 and the height-adjusting lower seat plate 8, which facilitates the horizontal transmission device 7 to adjust the movable step block 6 to move on the height-adjusting lower seat plate 8. Furthermore, a sliding groove can be provided on the height-adjusting lower seat plate 8, and the bottom of the movable step block 6 is placed in the sliding groove, so that the movable step block 6 can move along the sliding groove, and the sliding groove is used for limiting and guiding. Furthermore, a second polytetrafluoroethylene slide 14 is provided on the bottom surface of the movable step block 6 and the top surface of the height-adjusting lower seat plate 8. The friction between the second polytetrafluoroethylene slide 14 on the bottom surface of the movable step block 6 and the second polytetrafluoroethylene slide 14 on the top surface of the height-adjusting lower seat plate 8 is small, which facilitates the adjustment of the horizontal movement of the movable step block 6 when adjusting the height of the height-adjusting integrated support. Furthermore, the second polytetrafluoroethylene slide 14 on the top surface of the height-adjusting lower seat plate 8 is provided in the sliding groove.

[0042] The horizontal transmission device 7 can adjust the horizontal position of the movable step block 6 in the length direction of the positive step structure 61; in an optional embodiment, as Figure 4 and Figure 5 As shown, the horizontal transmission device 7 includes a mounting seat 71 and a screw 72. The mounting seats 71 are provided on both sides of the length direction of the positive step structure 61 of the movable step block 6. The bottom of the mounting seat 71 is connected to the height-adjusting lower seat plate 8. The screw 72 is arranged along the length direction of the positive step structure 61. The screw 72 is threaded through the movable step block 6 and the two mounting seats 71. One of the mounting seats 71 is provided with a motor 73, and the rotating shaft of the motor 73 is coaxially connected to the screw 72. The adjustment method of the motor-driven screw makes the adjustment accuracy of the horizontal position of the movable step block 6 in the length direction of the positive step structure 61 higher and easier to control.

[0043] The vertical lifting device 13 can lift the fixed step block 5; the vertical lifting device 13 includes two jacks, which are symmetrically arranged on both sides of the width direction of the positive step structure 61 of the movable step block 6, the lower ends of the jacks are arranged on the height-adjusting lower seat plate 8, and the upper ends are used to abut the height-adjusting upper seat plate 4, and the jacks can lift the height-adjusting upper seat plate 4 in the vertical direction; the height of the fixed step block 5 is adjusted by adjusting the height of the height-adjusting upper seat plate 4, which facilitates the arrangement of the vertical lifting device 13; wherein, Figure 2 As shown, the height of the lower seat plate 8 on both sides of the transverse bridge is smaller than the height in the middle of the transverse bridge, so that it is convenient to set jacks on both sides of the movable step block 6, avoiding the need for the jacks to directly support the bottom of the fixed step block 5, which causes the size of the fixed step block 5 to need to be set larger, and can minimize the size of the height-adjusting integrated support.

[0044] The upper end of the guide column 12 passes through the reserved hole on the height-adjusting upper seat plate 4, and the lower end passes through the reserved hole on the height-adjusting lower seat plate 8; the guide column 12 serves as a guide device for the vertical jacking device 13 to jack up the fixed step block 5, so that the rise and fall of the fixed step block 5 are relatively stable; and the guide column 12 can provide horizontal rigidity between the height-adjusting lower seat plate 8 and the height-adjusting upper seat plate 4. Figure 3 As shown, the height-adjustable upper seat plate 4 includes a top plate 41 and lower bosses 42 below the longitudinal bridge sides of the top plate 41, and the height-adjustable lower seat plate 8 includes a bottom plate 81 and upper bosses 82 arranged on the longitudinal bridge sides of the bottom plate 81. Reserved holes are set through the upper bosses 82 and the lower bosses 42, so that the guide columns 12 can be inserted into the height-adjustable upper seat plate 4 and the height-adjustable lower seat plate 8 to a deeper depth, providing greater horizontal rigidity and vertical guiding ability, and reserved holes are set at the corresponding positions of the four corners of the height-adjustable upper seat plate 4 and the height-adjustable lower seat plate 8. Four guide columns 12 are set, and the upper ends of the guide columns 12 pass through the reserved holes of the height-adjustable upper seat plate 4 and the lower ends pass through the reserved holes of the height-adjustable lower seat plate 8. The four guide columns 12 are arranged in a rectangular row, forming symmetry in both the transverse and longitudinal bridge directions.

[0045] In an optional embodiment, the height-adjusting integrated support further includes a transport protection device, which is arranged on both sides of the width direction of the positive step-shaped structure 61 of the movable step block 6. The transport protection device includes a connecting plate 11 and a plurality of connecting bolts 10. The connecting plate 11 is arranged vertically, and the upper end of the connecting plate 11 is connected to the height-adjusting upper seat plate 4 through part of the connecting bolts 10, and the lower end is connected to the height-adjusting lower seat plate 8 through the remaining part of the connecting bolts 10. Figure 4 As shown, the upper seat plate 4 includes a top plate 41 and lower bosses 42 below the longitudinal bridge on both sides of the top plate 41, and the lower seat plate 8 includes a bottom plate 81 and upper bosses 82 provided on both sides of the longitudinal bridge on the bottom plate 81. Figure 3 As shown, the vertically arranged connecting plate 11 is an L-shaped structure. The vertical plate of the L-shaped structure is arranged close to the outer side of the lower boss 42 and is connected to the lower boss 42 via connecting bolts 10. The horizontal plate of the L-shaped structure is connected to the bottom plate 81 via connecting bolts 10. The setting of the upper boss 82 facilitates the connecting plate 11 to connect the height-adjustable upper seat plate 4 and the height-adjustable lower seat plate 8 to achieve height limiting. During transportation, the upper end of the vertically arranged connecting plate 11 is connected to the height-adjustable upper seat plate 4 via some of the connecting bolts 10, and the lower end is connected to the height-adjustable lower seat plate 8 via the remaining connecting bolts 10. This can prevent problems such as bumps and damage caused by height changes between the movable step block 6 and the fixed step block 5.

[0046] The transverse bridge of the raised upper seat plate 4 is provided with retaining walls 22 on either side. These retaining walls 22 can be constructed of concrete or other structures that provide rigid positioning. The bottom of the retaining walls 22 is anchored to the bridge piers, utilizing the piers for stable load bearing. Anchoring methods such as anchor bolts can be used. The longitudinal bridge of the upper portion of the retaining wall 22 is connected to the limit stops 21 via shear members 23. These shear members 23 are positioned transversely, providing longitudinal positioning for the limit stops 21. The limit stop 21 is located on the outer side of the raised upper seat plate 4 and abuts against the side of the corresponding retaining wall 22 toward the raised upper seat plate 4. The limit stop 21 contacts the raised upper seat plate 4 and limits the transverse and longitudinal movement of the raised upper seat plate 4. Since the transverse direction is directly limited by the abutment relationship between the retaining wall 22 and the limit stop 21, and the longitudinal direction is limited by the force-bearing relationship between the retaining wall 22, the shear member 23 and the limit stop 21, the limiting strength in the transverse direction is greater than the limiting strength in the longitudinal direction. Under normal use conditions, especially under live load, the limit stop can be used to limit the horizontal displacement of the raised upper seat plate 4, ensuring the stability of the normal use state of the raised integrated support; and under earthquake conditions, the shear member 23 on which the limit stop is installed is sheared in the longitudinal direction, and the guide column plays a role of horizontal stiffness, limiting the horizontal displacement between the raised upper seat plate and the raised lower seat plate, bearing strong earthquake horizontal forces, and ensuring the safety of the bridge main beam.

[0047] In an optional embodiment, the shear member 23 is a mounting bolt, which can connect the limit block 21 and the retaining wall, and can simultaneously provide longitudinal bridge limiting capacity, and the longitudinal bridge limiting capacity is smaller than the transverse bridge limiting capacity.

[0048] In an optional embodiment, a first tetrafluoroethylene slide plate 213 is provided at the position where the limit block 21 contacts the upper seat plate 4 to reduce damage caused by friction. Figure 1 As shown, the corresponding positions where the limit stopper 21 contacts the height-adjusting upper seat plate 4 are respectively provided with first tetrafluoroethylene slide plates 213 .

[0049] In an optional embodiment, if Figure 2-Figure 3 As shown, the cross-section of the retaining wall 22 is a right-angled trapezoid, the transverse dimension of the top of the retaining wall 22 is smaller than the transverse dimension of the bottom of the retaining wall 22, and the side surface of the retaining wall 22 away from the height-adjustable upper seat plate 4 is an inclined surface, which can provide better resistance for the height-adjustable upper seat plate 4.

[0050] When the height-adjustable integrated support of this embodiment is raised, the vertical jack first lifts and raises the upper seat plate 4 to a predetermined position, and the contact surface of the movable step block 6 and the fixed step block 5 are separated; Figure 5For reference, the horizontal transmission device 7 pushes the movable step block 6 to the left until the vertical surface of the movable step block 6 is pressed against the vertical surface of the fixed step block 5; the vertical jack is completely unloaded, and the movable step block 6 is in contact with the fixed step block 5 and pressed against it.

[0051] When the height-adjustable integrated support of this embodiment is lowered, the vertical jack first lifts and raises the upper seat plate 4 so that the movable step block 6 is separated from the contact surface of the fixed step block 5. The lifting height can be half the step height. The step height refers to the height of the vertical surface of the step, which can be set according to needs, such as 2mm-10mm; Figure 5 For reference, the horizontal transmission device 7 pushes the movable step block 6 to the right until the requirements are met; the vertical jack is partially unloaded until the upper seat plate 4 is lowered to the designed height; the horizontal transmission device 7 pushes the movable step block 6 to the left until the vertical surface of the movable step block 6 is pressed against the vertical surface of the fixed step block 5; the vertical jack is completely unloaded, and the movable step block 6 is in contact with the fixed step block 5 and pressed tightly.

[0052] The integrated height adjustment support described in this embodiment is provided with a limit stop 21. Under normal operating conditions, particularly when subjected to live loads, the limit stop 21 limits the horizontal displacement of the upper height adjustment plate 4, ensuring the stability of the integrated height adjustment support during normal operation. During earthquake conditions, the mounting bolts of the limit stop 21 shear, allowing the guide post 12 to function, limiting the horizontal displacement between the upper height adjustment plate 4 and the lower height adjustment plate 8, thus absorbing the strong horizontal forces of the earthquake.

[0053] Example 2 A height adjustment method for adjusting the height adjustment integrated support described in Example 1, comprising the following steps: S01. Adjust the height of the fixed step block 5 to a level higher than a preset elevation by means of the vertical lifting device 13. The difference between the actual elevation of the fixed step block 5 and the preset elevation is less than one step height. S02. Horizontally adjust the movable step block 6 by the horizontal transmission device 7 until the vertical surface of the horizontally adjusted movable step block 6 abuts the vertical surface of the step of the fixed step block 5; wherein, the movable step block 6 is judged to abut against the fixed step block 5 by detecting the change in the force of the horizontally adjusted movable step block 6; a force sensor can be set on the motor to judge whether the movable step block 6 abuts against the fixed step block 5 by judging the change in the force provided by the motor, and then judge whether the horizontal displacement of the movable step block 6 is in place; S03. Lower the height of the fixed step block 5 to a preset elevation through the vertical lifting device 13.

[0054] The height adjustment method described in this embodiment adjusts the height of the fixed step block 5 to a level higher than the preset elevation and makes the actual elevation of the fixed step block 5 less than the height difference of the preset elevation by less than one step height, so that when the movable step block 6 is adjusted horizontally to a specified position, the vertical surface of the movable step block 6 will definitely abut the corresponding vertical surface of the fixed step block 5. Then, by detecting the change in the force of the horizontal adjustment of the movable step block 6, it is possible to determine whether the movable step block 6 abuts against the fixed step block 5 and whether the movable step block 6 is raised to the correct position. This judgment method is simple and makes the adjusted movable step block 6 have the strongest support capacity for the fixed step block 5. Example 3 like Figure 6 As shown, an intelligent height adjustment system includes a height monitoring subsystem, a height adjustment control subsystem and a height adjustment mechanical subsystem.

[0055] The elevation monitoring subsystem can monitor the elevation changes of the bridge main beam or the pier top, and send the monitoring results to the height control subsystem in the form of electrical signals; wherein, the elevation monitoring points of the elevation monitoring subsystem are generally set at intervals in the longitudinal direction of the entire bridge. The elevation monitoring subsystem mainly realizes the changes in the elevation of the beam or the pier top through the static level and the satellite monitoring system, so as to achieve the purpose of multi-channel and multi-level data monitoring and improve the reliability of the data; the satellite positioning elevation monitoring collects the elevation monitoring data of the beam and the pier through the on-site monitoring points, and the on-site monitoring points then transmit the data to the data storage terminal through 2 / 3 / 4G wireless. The terminal supports MQTT, HTTP, TCP / IP and other Internet of Things communication protocols, and also has an open data interface, which can easily realize the docking of data and third-party platforms. The data acquisition terminal set up in the elevation monitoring system has the function of communicating with the storage terminal of the satellite positioning monitoring system. First, the data acquisition terminal and the storage terminal are interconnected through a specific communication protocol. Then, the satellite elevation monitoring data is obtained in real time according to the data acquisition instructions. Finally, the elevation data collected by the static level is fused with the elevation data monitored by satellite positioning. The two verify each other and improve the reliability of the data monitoring system.

[0056] The height adjustment control subsystem can determine whether the height of the height adjustment integrated support needs to be adjusted based on the monitoring results and the preset threshold. The height adjustment control subsystem consists of a master station and a substation. Each pier is equipped with a substation. The master station controls the substation and communicates with the elevation monitoring subsystem. The master station adjusts the height of the height adjustment integrated support by controlling the horizontal movement of the jack and the movable step block 6. The functions of the master station mainly include the following aspects: (1) Receive data from each measuring point and receive Beidou positioning system data in real time; (2) Communicate with the remote server; (3) Monitoring the entire bridge elevation and determining whether adjustment is required and the amount of adjustment; (4) Communicate with substations and be responsible for sending and receiving control commands of each substation.

[0057] The functions of the substation are as follows: (1) Adjust the support height according to the control target of the communication station; (2) Report the real-time displacement of the screw caused by the extension and contraction of the hydraulic cylinder and the rotation of the motor of the jack; (3) Fault diagnosis: real-time determination of the current operating status of the height adjustment support and emergency response plan.

[0058] The height adjustment mechanical subsystem includes the height adjustment integrated support, and the horizontal transmission device 7 and the vertical jacking device 13 of the height adjustment integrated support are both automatic adjustment devices; when the height adjustment control subsystem determines that the height of the height adjustment integrated support needs to be adjusted, the height adjustment control subsystem sends the adjustment plan in the form of a height adjustment instruction to the horizontal transmission device 7 and the vertical jacking device 13 of the height adjustment mechanical subsystem, and the horizontal transmission device 7 and the vertical jacking device 13 adjust the height of the height adjustment integrated support according to the height adjustment instruction.

[0059] The intelligent height adjustment system provided by the present invention can intelligently adjust the height of the integrated support according to the changes in the elevation of the bridge main beam or the pier top. It has higher real-time performance and is conducive to ensuring the safety of the bridge.

[0060] Example 4 An intelligent height adjustment method, using the intelligent height adjustment system described in Example 3 to adjust the height, includes the following steps: S1: Start the intelligent height adjustment system to determine whether the height adjustment control subsystem and elevation monitoring subsystem are abnormal; if there is no abnormality, proceed to the next step; S2: The height adjustment control subsystem reads the elevation monitoring subsystem to monitor the elevation change of the bridge main beam or pier top, verifies the deformation data, and determines whether the height adjustment integrated bearing needs to be raised; if so, proceeds to the next step; S3: The height adjustment control subsystem determines whether it is within the adjustment time window according to the preset time node; if so, proceed to the next step; S4: The height adjustment control subsystem sends a height adjustment command to the horizontal transmission device 7 and the vertical lifting device 13 of the height adjustment mechanical subsystem. The horizontal transmission device 7 and the vertical lifting device 13 adjust the height of the height adjustment integrated support according to the height adjustment command. The height adjustment process controlled by the height adjustment instruction can be a one-time height adjustment method, such as the height adjustment method in Example 2; or a repeated single-step adjustment method can be used. When the repeated single-step adjustment method is used, in step S4, the height adjustment instruction includes a total height increase instruction or a total height decrease instruction for the integrated support. The vertical lifting device 13 is used to lift the fixed stair block 5, so that the height difference between the stair elevation of the inverted stair structure 51 and the stair elevation of the positive stair structure 61 is greater than one stair height and less than two stair heights. The horizontal transmission device 7 is then used to adjust the movable stair block 6 horizontally until the vertical surface of the horizontal movable stair block 6 abuts against the vertical surface of the stair block 5. The vertical lifting device 13 is then used to unload the fixed stair block 5 so that the fixed stair block 5 sits on the movable stair block 6, thus completing the single-step lifting. After the ladder is raised, the integrated height-adjusting support is safety-checked; for example: the fixed step block 5 is lifted by the vertical jacking device 13 by 1.5 steps, so that the horizontal adjustment of the movable step block 6 by the horizontal transmission device 7 is not affected, and then the movable step block 6 is horizontally adjusted by the horizontal transmission device 7 until the vertical surface of the step of the horizontally adjusted movable step block 6 abuts against the vertical surface of the step of the fixed step block 5, which can achieve guidance, and then the vertical jacking device 13 is unloaded to make the fixed step block 5 drop by 0.5 steps and sit on the movable step block 6, completing the single-step raising; the integrated height-adjusting support is safety-checked after the single-step raising, and if it is safe, the next repetition is performed until the height of the fixed step block 5 is adjusted to the preset elevation.

[0061] Total lowering instruction: Repeat the single-step lowering instruction and the lowering detection instruction until the height of the fixed step block 5 is adjusted to the preset elevation; wherein the single-step lowering instruction is: lift the fixed step block 5 by the vertical lifting device 13 so that the height difference of the step elevation of the inverted step structure 51 after lifting is less than one step height than the height difference of the step elevation of the positive step structure 61 directly below; then horizontally adjust the movable step block 6 by the horizontal transmission device 7 until the distance between the step vertical surface of the movable step block 6 and the step vertical surface corresponding to the horizontal level of the fixed step block 5 is adjusted. The distance is greater than one step width and less than two step widths; then the vertical jacking device 13 is used to unload and the fixed step block 5 is lowered to one step height; then the movable step block 6 is horizontally adjusted through the horizontal transmission device 7 until the vertical surface of the horizontally adjustable movable step block 6 abuts against the horizontal vertical surface of the fixed step block 5; finally, the vertical jacking device 13 is unloaded and the fixed step block 5 is seated on the horizontally adjustable movable step block 6 to complete the single-step lowering; wherein, the lowering detection instruction: perform a safety detection on the height-adjusting integrated support after the single-step lowering. For example, the fixed step block 5 is lifted by the vertical lifting device 13 by 0.5 step height, so that the horizontal transmission device 7 horizontally adjusts the movable step block 6 without being affected; then the horizontal transmission device 7 horizontally adjusts the movable step block 6 until the distance between the step vertical surface of the horizontally adjusted movable step block 6 and the step vertical surface corresponding to the fixed step block 5 is 1.5 step widths, so that the fixed step block 5 is not affected by the unloading of the vertical lifting device 13; then the fixed step block 5 is lowered by one step height through the vertical lifting device 13 to facilitate the judgment of the lowering height. At the same time, the horizontal transmission device 7 can be used to horizontally adjust the movable step block 6 by half the step width, until the vertical surface of the horizontally adjustable movable step block 6 abuts against the horizontal vertical surface of the fixed step block 5. After abutting, vertical guidance can be achieved, and finally the fixed step block 5 is unloaded by the vertical jacking device 13 to lower the fixed step block 5 by 0.5 step height and sit on the horizontally adjustable movable step block 6, completing the single-step lowering; the height adjustment integrated support is safety tested after the single-step lowering, and if it is safe, the next step is repeated until the height of the fixed step block 5 is adjusted to the preset elevation. By testing after the single-step raising or lowering, the height adjustment operation can be made safer and is conducive to matching the operation window. The above-mentioned single-step raising and lowering method is also a method for adjusting the height of the integrated support, and compared with the one-time adjustment method of Example 2, its adjustment process is safer. In addition, a force sensor can also be set on the motor for the single-step raising and lowering method. By judging the change in the force provided by the motor, it can be determined whether the movable step block 6 is in contact with the fixed step block 5, and then whether the horizontal displacement of the movable step block 6 is in place.

[0062] S5: After the height of the integrated support is adjusted into place, the height control subsystem reads the elevation monitoring subsystem to monitor the elevation changes of the bridge main beam or pier top, and conducts elevation review. If the elevation review meets the requirements, the height adjustment is completed.

[0063] The intelligent height adjustment method described in this embodiment can ensure the correctness of the subsequent judgment on whether to increase the height by judging whether the height adjustment control subsystem and the elevation monitoring subsystem are abnormal; and after determining that the height adjustment is required, the height adjustment control subsystem judges whether it is in the adjustment time window according to the preset time node, which can ensure the safety of the subsequent height adjustment operation; after the height adjustment is completed, the height adjustment control subsystem reads the elevation monitoring subsystem to monitor the elevation changes of the bridge main beam or the pier top, and performs elevation review, which can ensure the accuracy of whether the height adjustment operation is completed. It can quickly and orderly intelligently adjust the height of the integrated height adjustment support in real time through the sequence, which has high timeliness, high safety and high accuracy, and is conducive to ensuring the safety of the bridge.

[0064] Furthermore, in step S2, the engineering department verifies the deformation data to determine whether the integrated support needs to be raised; In step S4, the engineering department fills in the height adjustment data, and the height adjustment control subsystem verifies whether the height adjustment amount is within the travel range. After confirmation, the height adjustment control subsystem sends a height adjustment instruction to the horizontal transmission device 7 and the vertical jacking device 13 of the height adjustment mechanical subsystem. The horizontal transmission device 7 and the vertical jacking device 13 adjust the height of the integrated height adjustment support according to the height adjustment instruction.

[0065] By having the engineering department verify the deformation data, determine whether the integrated bearing needs to be raised and fill in the raising data, the accuracy and safety of the raising can be further improved.

[0066] 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 and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
