Bridge support displacement self-compensation monitoring device

Abstract

This utility model discloses a bridge bearing displacement self-compensating monitoring device, belonging to the technical field of bridge monitoring equipment. It includes a bearing pile collar, with a bearing pile body fixed to the inner wall of the collar. An upper bearing plate is tightly fitted to the top of the bearing pile body, and vertical support rods are fixed to the corners of the bottom surface of the upper bearing plate. The monitoring device uses four sets of high-precision resistance displacement gauges connected to the center of the four perimeters of the upper and lower bearing plates to simultaneously monitor the angles around the bearing. Combined with a connected intelligent control unit, it promptly captures changes in force and displacement of the upper bearing plate. When monitoring information in one direction is insufficient, it can simultaneously monitor changes in other directions to accurately determine whether the bearing has indeed shifted. This allows for adjustment and upgrading of the support compensation using hydraulic jacking piles in the corresponding direction, providing temporary support and reinforcement for subsequent repairs, and improving safety while monitoring.

Description

Technical Field

[0001] This utility model relates to the technical field of bridge monitoring equipment, specifically a bridge bearing displacement self-compensation monitoring device. Background Technology

[0002] Bridge bearings generally consist of an upper steel plate fixed to the upper part of the bridge, such as the main beam; a bearing body made of rubber located at the mid-height; and a lower steel plate fixed to the lower part of the bridge, such as the pier. In actual use, due to various objective factors such as upper loads, structural self-weight, and material aging, bridge bearing displacement often occurs. Essentially, bridge bearing displacement is a relative displacement between the upper and lower steel plates. Specifically, it manifests as displacement of the upper steel plate, such as bearing detachment, excessive bearing compression, and horizontal misalignment. This increases the pressure on certain components, impairing the bridge's performance and potentially damaging the main beam. Therefore, once bridge bearing displacement exceeds a predetermined value, it must be detected as early as possible and an alarm triggered immediately to facilitate timely manual resetting. In recent years, many monitoring structures have emerged that remotely alarm when bridge bearing displacement exceeds a predetermined value, or exceeds the limit. Upon receiving the alarm signal, a receiving terminal, such as a computer, allows for timely manual resetting.

[0003] A Chinese patent website (patent publication number CN218443816U) discloses a bridge bearing condition monitoring device, including a main housing fixedly installed on the top of a pier. A threaded column is rotatably connected inside the main housing, and a threaded block is threadedly connected to the outside of the threaded column. The threaded block slides within the main housing and is limited in position. An adjusting plate is fixedly installed at the front end of the threaded block, and a support column is fixedly connected to the top end of the adjusting plate. The top end of the support column slides through the top end of the main housing, extends to the outside, and is fixedly connected to a support seat. A displacement sensor is fixedly installed at the top end of the support seat.

[0004] The aforementioned bridge monitoring equipment provides users with real-time data to monitor the real-time condition of the bridge structure, thereby detecting whether the overall device has failed and replacing it in time, thus extending the service life of the bridge structure. However, such monitoring devices cannot perform comprehensive detection and alarms around the entire structure. For example, in cases of excessive compression displacement, i.e., local displacement of the upper steel plate, a monitoring device with only one direction cannot determine whether there is displacement of the entire support. Furthermore, such monitoring devices still require manual on-site repair after detecting displacement, and cannot provide pre-compensation measures, exhibiting periodicity. Therefore, we propose a bridge support displacement self-compensation monitoring device. Utility Model Content

[0005] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.

[0006] The purpose of this invention is to provide a bridge bearing displacement self-compensation monitoring device to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a bridge bearing displacement self-compensating monitoring device, comprising a bearing pile collar, a bearing pile body fixed to the inner wall of the bearing pile collar, an upper bearing plate tightly fitted to the top of the bearing pile body, vertical support rods fixed to the corners of the bottom surface of the upper bearing plate, a lower bearing plate fixed to the bottom surface of the support rods, hydraulic jacking piles fixed to the center of the edges of the top surface of the lower bearing plate, a high-precision resistance displacement meter aligned with the side with the hydraulic jacking pile, movable frames axially connected to the upper and lower ends of the high-precision resistance displacement meter, an installation frame fixed to one side of the movable frame, fixing bolts passing through the inner two sides of the installation frame, and a control cabinet fixed to one side of the top surface of the lower bearing plate.

[0008] Furthermore, the center of the bottom surface of the upper seat plate is connected to the center of the top surface of the lower seat plate through the support pile, and the four corners of the bottom surface of the upper seat plate are supported by the support rods around the top surface of the lower seat plate.

[0009] Furthermore, the high-precision resistance displacement gauge and the hydraulic jacking pile are arranged at equal intervals around the center of the upper and lower base plates, and the hydraulic jacking pile maintains support between the upper and lower base plates.

[0010] Furthermore, the two ends of the high-precision resistive displacement gauge are connected to the mounting frame via a movable bracket, and the mounting frame is fixed to the center of the four perimeters of the upper and lower base plates by fixing bolts.

[0011] Furthermore, the control cabinet is electrically connected to a high-precision resistance displacement meter, and the control cabinet is also connected to a hydraulic jacking pile.

[0012] Furthermore, the control cabinet includes a cabinet housing, a display panel is fixed to one side of the top of the cabinet housing, a hydraulic power unit is fixed to the display panel, an intelligent control unit is distributed on one side of the hydraulic power unit, and the hydraulic power unit is connected to the hydraulic jacking pile oil circuit.

[0013] Furthermore, the hydraulic power unit and the intelligent control unit are fixed to the cabinet housing, and the intelligent control unit is electrically connected to the display panel.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] The monitoring device uses four sets of high-precision resistance displacement gauges connected to the center of the four perimeters of the upper and lower support plates to simultaneously monitor the angles around the support. Each set of high-precision resistance displacement gauges is connected between the upper and lower support plates by a mounting bracket. Together with the connected intelligent control unit, it can capture the force changes and displacement phenomena of the upper support plate in a timely manner. When the monitoring information in a single direction is insufficient, it can combine the changes in the monitoring information in other directions to accurately determine whether the support has indeed displaced. Then, the hydraulic jacking piles in the corresponding direction can be used to adjust and upgrade the support compensation, providing temporary support and reinforcement for subsequent repairs, and improving safety while monitoring.

[0016] The hydraulic power unit of this monitoring device consists of a hydraulic pump station, an oil tank, a solenoid valve group, and an oil circuit system. The oil circuit system is connected to the hydraulic jacking pile to adjust the oil pressure and drive the jacking force to adjust and compensate the support. The intelligent control unit is equipped with a PLC controller that executes synchronous algorithms, such as PID control, to process high-precision resistance displacement gauge data and output commands for regulation.

[0023] It should also be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings. Unless otherwise specified, the embodiments and features described in this disclosure can be combined with each other.

[0025] It should be noted that the terms "a" and "a plurality of" used in this disclosure are illustrative rather than restrictive, and those skilled in the art should understand that, unless otherwise expressly indicated in the context, they should be understood as "one or more".

[0026] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0027] This utility model provides, for example Figure 1-4 The bridge bearing displacement self-compensation monitoring device shown includes a bearing pile collar 1, a bearing pile body 2 fixed to the inner wall of the bearing pile collar 1, an upper bearing plate 3 tightly attached to the top of the bearing pile body 2, vertical support rods 4 fixed at the corners of the bottom surface of the upper bearing plate 3, a lower bearing plate 5 fixed to the bottom surface of the support rods 4, hydraulic jacking piles 6 fixed at the center of the edges of the top surface of the lower bearing plate 5, a high-precision resistance displacement meter 7 aligned with one side of the hydraulic jacking pile 6, a movable frame 8 axially connected to both the upper and lower ends of the high-precision resistance displacement meter 7, an installation frame 9 fixed to one side of the movable frame 8, fixing bolts 10 passing through the inside two sides of the installation frame 9, and a control cabinet 11 fixed to one side of the top surface of the lower bearing plate 5.

[0028] To provide this monitoring device with high-precision monitoring and auxiliary support compensation functions for bridge bearings, such as Figure 1-4 As shown, this monitoring device can simultaneously monitor the angles around the support by connecting four sets of high-precision resistance displacement gauges 7 distributed around the four perimeters of the upper support plate 3 and the lower support plate 5. Each set of high-precision resistance displacement gauges 7 is connected between the upper support plate 3 and the lower support plate 5 by a mounting bracket 9. In conjunction with the connected intelligent control unit 1104, the device can capture the force changes and displacement phenomena of the upper support plate 3 in a timely manner. When the monitoring information in a single direction is insufficient, it can cooperate with the changes in the monitoring information in other directions to accurately determine whether the support has indeed displaced. Thus, the hydraulic jacking piles 6 in the corresponding direction can be used to adjust and upgrade the support compensation, providing temporary support and reinforcement for subsequent repairs.

[0029] like Figure 3-4As shown, the control cabinet 11 includes a cabinet housing 1101. A display panel 1102 is fixed to one side of the top of the cabinet housing 1101. A hydraulic power unit 1103 is fixed to the display panel 1102. An intelligent control unit 1104 is distributed on one side of the hydraulic power unit 1103. The hydraulic power unit 1103 is connected to the hydraulic lifting pile 6 by an oil circuit.

[0030] To facilitate the adjustment and compensation operation of the hydraulic jacking pile 6, such as Figure 3-4 As shown, the control cabinet 11 of this monitoring device is equipped with a hydraulic power unit 1103 and an intelligent control unit 1104. The hydraulic power unit 1103 consists of a hydraulic pump station, an oil tank, a solenoid valve group and an oil circuit system. It is connected to the hydraulic jacking pile 6 through the oil circuit system to adjust the oil pressure and drive the jacking force to adjust and compensate the support. The intelligent control unit 1104 is equipped with a PLC controller that executes synchronous algorithms, such as PID control, processes the data of the high-precision resistance displacement gauge 7 and outputs commands for regulation.

[0031] In summary, when using this monitoring device, firstly, four sets of high-precision resistance displacement gauges 7 are attached to the middle positions of the corresponding upper and lower base plates 3 and 5 via mounting brackets 9 connected at both ends, and fixed with fixing bolts 10. At the same time, hydraulic jacking piles 6 are placed on the device, with their tops in contact with the bottom surface of the upper base plate 3. During the monitoring process, if displacement occurs in a certain direction of the upper base plate 3, the processor will simultaneously collect data from the high-precision resistance displacement gauges 7 in that direction and data from the high-precision resistance displacement gauges 7 in other directions to determine whether displacement has indeed occurred. Subsequently, the control cabinet 11 is adjusted to control the hydraulic jacking piles 6 to assist in lifting or lowering in the direction of displacement, maintaining the stability of the horizontal support force of the support seat and providing monitoring and compensation functions.

[0032] The above description is merely a selection of preferred embodiments of this disclosure and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the utility model involved in the embodiments of this disclosure is not limited to the technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the above-described inventive concept. For example, technical solutions formed by substituting the above features with (but not limited to) technical features with similar functions disclosed in the embodiments of this disclosure.
