Description

Technical Field

[0001] This invention belongs to the field of bridge technology, specifically relating to a bridge load monitoring support. Background Technology

[0002] As is well known, the rapid development of bridge engineering has powerfully promoted the coordinated development of regional economies and the integration of cultural exchanges. During bridge construction and operation, accurately obtaining the load at the bridge's support locations is of paramount importance for the bridge's operational safety and maintenance. During construction, load measurements on the superstructure allow for monitoring the stress state of the bridge structure at each stage. When uneven loading or overloading occurs, timely adjustments can be made to ensure construction safety and progress. During operation, long-term monitoring of bridge loads can provide early warning signals for bridges in cases of special weather, traffic conditions, or abnormal operational status, providing a basis and guidance for bridge maintenance, repair, and management decisions.

[0003] However, most current bridge force measurement bearings are pot bearings, which measure the lateral pressure of the rubber plate inside the bearing under different vertical pressures, and then convert the compressive stress into an electrical signal output through a pressure transmitter. This force measurement method of the bearing will have the following problems:

[0004] (1) The lateral compressive stress of the same bearing rubber sheet will vary greatly when it is subjected to pressure at different temperatures. This method is greatly affected by temperature, and the accuracy of the measured force value is not high.

[0005] (2) This method requires on-site calibration. The laboratory environment differs greatly from the project site environment. Therefore, the error of the pot-type force measuring support after laboratory calibration will still be large during on-site measurement.

[0006] (3) The force measuring support only needs to measure the vertical pressure. However, in actual operation, the displacement, rotation angle, horizontal shear resistance, vertical tensile resistance and other functions of the support need to be considered. Therefore, the force measuring support structure will inevitably become more complicated and costly. Summary of the Invention

[0007] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide an improved bridge load monitoring support that is simple in structure, clear in force transmission, accurate in force measurement, and cost-saving.

[0008] To solve the above technical problems, the present invention adopts the following technical solution: a bridge load monitoring support, comprising an anchoring assembly, an upper support, a lower support, a force measuring component, a middle support, a middle support pull ring, and an elastic basin block, wherein an upper basin ring is formed on one of the lower part of the upper support and the upper part of the middle support, and an upper plug is formed on the other; a lower basin ring is formed on one of the lower part of the middle support and the upper part of the lower support, and a lower plug is formed on the other; the upper plug cooperates with the inner wall and / or outer wall of the upper basin ring to form an upper cavity, and the lower plug cooperates with the inner wall and / or outer wall of the lower basin ring to form a lower cavity; the force measuring component is a spoke-type force sensor, one of the spoke-type force sensor and the elastic basin block is located in the upper cavity, and the other is located in the lower cavity; the middle support pull ring connects the middle support to the upper support or the lower support on which the spoke-type force sensor is installed.

[0009] Preferably, the middle seat includes a middle seat plate, with an upper plug and a lower plug located at the top and bottom of the middle seat plate, respectively, and integrally formed; the upper basin ring is integrally formed with the upper seat, and the lower basin ring is integrally formed with the lower seat. This facilitates the assembly and forming of the support and reduces production costs.

[0010] According to a specific embodiment and preferred aspect of the present invention, the upper and lower plugs are symmetrically arranged, each including a first plug body and a second plug body extending outward from the surface of the middle seat plate and concentrically. The outer diameter of the second plug body is larger than that of the first plug body, and the outer diameter of the second plug body is smaller than that of the middle seat plate. When forming the upper and lower cavities, the second plug body is attached to the inner wall of the upper and lower basin rings from its outer wall surface. This design not only meets the requirement of stability of the formed upper and lower cavities, but also ensures that when the support is subjected to a horizontal force, the horizontal force is limited by the basin ring and plug of the support, ensuring that the force sensor installed in the support cavity is only subjected to pressure and not horizontal shear force. Therefore, it not only protects the force sensor but also ensures the measurement accuracy of the force sensor.

[0011] Preferably, the spoke-type force sensor is installed in the upper cavity and abuts against the top and bottom of the upper cavity. The elastic basin block fills the lower cavity and abuts against the top and bottom of the lower cavity. The elastic basin block forms a notch around its circumference from its top edge, and a sealing ring is placed at the notch. A middle seat pull ring connects the middle seat plate to the upper seat. In this example, the sealing ring is made of brass. The notch design facilitates the placement of the sealing ring, effectively preventing deformation that could cause it to become stuck between the plug and the cavity, thus affecting the movement of the plug relative to the cavity when the elastic basin block is under force. Furthermore, brass has a long service life.

[0012] The spoke-type force sensor is placed inside the cavity of the upper plate. The vertical bearing capacity is determined by the design load. The design load range of a single force sensor is 500KN~10000KN; the temperature range of the sensor is -30~+70℃; the overall accuracy of the sensor is 0.5%FS; and the safe overload range is 120%FS.

[0013] In this example, the force sensor has bolt holes on its upper side for bolting to the upper support plate, preventing the sensor from undergoing horizontal displacement or rotation inside the support during bridge operation.

[0014] The elastic pot block is a hyperelastic body. When the lower bearing plate of the support constrains the rubber pot block horizontally and radially, the vertical load-bearing capacity of the pot block is greatly improved, while also meeting the requirements of bridge deformation for rotation and displacement. Therefore, the bearing and rotation functions of the support are fully utilized.

[0015] Preferably, an upper hook is formed on the outer periphery of the upper basin ring, and a lower hook is formed on the middle seat ring to cooperate with the upper hook, and the upper hook and lower hook are hooked together. The lower part of the middle seat ring is connected to the middle seat plate. The purpose is to form an interlocking structure to resist accidental overturning moments and protect the support and internal force sensor.

[0016] According to another specific embodiment and preferred aspect of the present invention, an upper basin ring is formed at the upper part of the middle seat, and a lower plug is formed at the lower part of the middle seat; the upper seat includes an upper seat plate and an upper plug; the lower seat includes a lower seat plate and a lower basin ring, an elastic basin block is filled in the upper cavity, and the elastic basin block forms a notch around its circumference from its top edge, a sealing ring is placed at the notch, and a spoke-type force sensor is installed in the lower cavity. Specifically, the sealing ring is made of brass. In this example, the sealing ring is made of brass. Here, the notch design facilitates the placement of the sealing ring, thus effectively preventing the elastic basin block from getting stuck between the plug and the cavity due to deformation when subjected to force, thereby affecting the movement of the plug relative to the cavity. At the same time, brass has a long service life.

[0017] Preferably, the lower plug head includes a first plug body extending downward from the bottom of the upper basin ring and a second plug body continuing downward from the first plug body. The outer diameter of the upper basin ring is larger than the outer diameter of the second plug body, and the outer diameter of the second plug body is larger than the outer diameter of the first plug body, forming an upper hook. A middle seat pull ring is installed on the top of the lower basin ring and forms a lower hook with the lower basin ring. When the lower cavity is formed, the upper hook and lower hook cooperate to form an interlocking structure, resisting accidental overturning moments and protecting the support and internal force sensor.

[0018] Furthermore, the upper plug head includes a concentric third plug body and a fourth plug body, wherein the outer diameter of the fourth plug body is larger than the outer diameter of the third plug body, the third plug body is fixedly connected to the bottom of the upper seat plate and is integrally formed; or the third plug body is unidirectionally or bidirectionally slidably connected to the upper seat plate through a linear sliding connector to form the upper cavity, and the fourth plug body fits against the inner wall surface of the upper basin ring from the outer wall surface.

[0019] In addition, there is one spoke-type force sensor, and its center is aligned with the center of the lower cavity or the upper cavity; or there are multiple spoke-type force sensors, which are evenly distributed around the lower cavity or the upper cavity with the center of the lower cavity or the upper cavity as a reference.

[0020] Preferably, the bridge load monitoring bearing also includes a signal port connected to the spoke-type force sensor and a data display instrument connected to the signal port.

[0021] Due to the implementation of the above technical solutions, the present invention has the following advantages compared with the prior art:

[0022] This invention not only meets the requirements of bridge bearings for load-bearing capacity, displacement, and rotation angle, but also accurately measures the superstructure load of bridges under only vertical pressure, providing a basis and guidance for bridge maintenance, repair, and management decisions. Furthermore, the spoke-type force sensor, which can directly read data, has a wide applicable temperature range, does not require on-site calibration, and is highly practical.

[0038] Example 1

[0039] like Figure 1 and Figure 2 As shown, the bridge load monitoring support in this embodiment includes an anchoring component 1, an upper support 2, a lower support 3, a force measuring component 4, a middle support 5, a middle support pull ring 6, and an elastic basin block 7.

[0040] Specifically, the anchoring component 1 includes anchor bolts 10 and pre-embedded anchors 11. The function of the anchoring component 1 is to connect the support with the bridge structure and the substructure of the bridge piers.

[0041] Combination Figure 3 As shown, the upper seat 2 includes an upper seat plate 20 and an upper basin ring 21 located at the bottom of the upper seat plate 20, wherein the upper seat plate 20 and the upper basin ring 21 are integrally formed.

[0042] In this example, an upper hook 210 is formed on the outer periphery of the upper basin ring 21, and a lower hook 60 is formed on the middle seat ring 6 to cooperate with the upper hook 210, and the upper hook 210 and the lower hook 60 are hooked together. The purpose is to form an interlocking structure to resist accidental overturning moments and protect the support and internal force sensor.

[0043] The middle seat 5 includes a middle seat plate 50, and the top and bottom of the middle seat plate 50 form an upper plug 51 and a lower plug 52, respectively.

[0044] In this example, the middle seat plate 50, the upper plug 51, and the lower plug 52 are integrally formed.

[0045] Meanwhile, the upper plug 51 and the lower plug 52 are arranged symmetrically, one above the other.

[0046] Specifically, the upper plug head 51 includes a first plug body 511 and a second plug body 512 extending outward from the surface of the middle seat plate 50 and concentrically, wherein the outer diameter of the second plug body 512 is larger than the outer diameter of the first plug body 511, and the outer diameter of the second plug body 512 is smaller than the outer diameter of the middle seat plate 50.

[0047] Based on symmetry, the structure of the lower plug 52 is also very clear.

[0048] The lower seat 3 includes a lower seat plate 30 and a lower basin ring 31 formed on the lower seat plate 30, wherein the lower basin ring 31 is integrally formed with the lower seat plate 30.

[0049] In this example, during support assembly, the upper basin ring 21 and the upper plug 51 form the upper cavity S1, and the lower basin ring 31 and the lower plug 52 form the lower cavity S2. The force-measuring component 4 is located in the upper cavity S1, and the elastic basin block 7 is installed in the lower cavity S2. When forming the upper and lower cavities, the second plug 512 adheres to the inner walls of the upper basin ring 21 and the lower basin ring 31 from its outer wall surface. This design not only meets the stability requirements of the formed upper and lower cavities, but also ensures that when the support is subjected to horizontal force, the horizontal force is limited by the basin rings and plug of the support, guaranteeing that the force sensor installed in the support cavity is only subjected to pressure and not horizontal shear force. Therefore, it not only protects the force sensor but also ensures the measurement accuracy of the force sensor.

[0050] The spoke-type force sensor is installed in the upper cavity S1 and abuts between the top and bottom of the upper cavity S1.

[0051] In this example, the force sensor has bolt holes on its upper side for bolting to the upper support plate, preventing the sensor from undergoing horizontal displacement or rotation inside the support during bridge operation.

[0052] There is one spoke-type force sensor, and its center is aligned with the center of the cavity.

[0053] Of course, combined Figure 4 As shown, there can be multiple spoke-type force sensors, which are evenly distributed around the circumference of the cavity, with the center of the cavity as the reference. In other words, when the vertical design load is large, two, three, four, or even more force sensors can be configured inside the support, arranged evenly and symmetrically, so that each force sensor can work together to bear the load.

[0054] Meanwhile, the spoke-type force sensor is placed inside the cavity of the upper plate. The vertical bearing capacity is determined by the design load. The design load range of a single force sensor is 500KN~10000KN; the temperature range of the sensor is -30~+70℃; the overall accuracy of the sensor is 0.5%FS; and the safe overload range is 120%FS.

[0055] The elastic basin 7 fills the lower cavity S2 and abuts between the top and bottom of the lower cavity S2, wherein the elastic basin 7 forms a notch 70 around itself from the top edge.

[0056] In other words, the elastic pot block 7 is a hyperelastic body. After the lower seat plate 20 constrains the rubber pot block horizontally and radially, the vertical bearing capacity of the pot block is greatly improved. At the same time, it can meet the requirements of bridge deformation for rotation and displacement. Therefore, the bearing and rotation functions of the support are brought into play.

[0057] In this example, a sealing ring 71 is placed at the notch 70, and the sealing ring 71 is made of brass. The notch 70 design facilitates the placement of the sealing ring 71, thus effectively preventing deformation of the elastic basin block 7 from causing it to become stuck between the plug and the cavity, affecting the movement of the plug relative to the cavity when force is applied. Furthermore, brass has a long service life.

[0058] Meanwhile, the upper part of the middle seat pull ring 6 is hooked with the upper basin ring 21, and the lower part is fixedly connected to the middle seat plate 50 by connecting bolts.

[0059] In addition, a through hole is provided on one side of the upper basin ring 21, and the bridge load monitoring support also includes a signal port 8 connected to the spoke-type force sensor and a data display instrument 9 connected to the signal port 8.

[0060] Specifically, signal port 8 is installed in the through hole and is connected to the data display instrument 9 via a data transmission line.

[0061] In this example, the data display unit 9 is used to provide intuitive feedback on the measured load data. The data display unit 9 can be designed with DC power or battery power for convenient field operations.

[0062] In summary, this embodiment has the following advantages:

[0063] 1. Compared to traditional pot bearings, this type of bearing has a simpler structure, more direct force transmission, and clearly defined functions for each component, ensuring no interference between them. The force measurement system is only subjected to vertical pressure, while the displacement and rotation requirements of the bearing are met by the traditional pot bearing.

[0064] 2. Through structural design, the sensor is only subjected to vertical pressure when operating on the support, and is not subjected to horizontal shear force, rotation, or bending moment, thus ensuring measurement accuracy and safe operation of the sensor.

[0065] 3. Force sensors do not need to sense changes in the properties of rubber materials, have a wide applicable temperature range, and do not require on-site calibration. After calibration at the factory, accurate force measurement can be achieved on-site.

[0066] Example 2

[0067] like Figure 5 As shown, the structure of the bridge load monitoring support in this example is basically the same as that in Example 1. The difference is that this example is a fixed force measuring support.

[0068] Specifically, the upper seat 2 includes an upper seat plate 20 and an upper plug head 51 located at the bottom of the upper seat plate 20, wherein the upper seat plate 20 and the upper plug head 51 are integrally formed.

[0069] An upper basin ring 21 is formed on the upper part of the middle seat 5, and a lower plug head 52 is formed on the lower part of the middle seat 5. The lower plug head 52 includes a first plug body 521 extending downward from the bottom of the upper basin ring and a second plug body 522 extending downward from the first plug body 521. The outer diameter of the upper basin ring 21 is larger than the outer diameter of the second plug body 522, and the outer diameter of the second plug body 522 is larger than the outer diameter of the first plug body 521, and it forms an upper hook.

[0070] The lower seat 3 includes a lower seat plate 30 and a lower basin ring 31 located on the lower seat plate 30.

[0071] In this example, the upper plug 51 is inserted into the upper basin ring 21 to form the upper cavity S1, and the lower plug 52 is inserted into the lower basin ring 31 to form the lower cavity S2. When the support is subjected to a horizontal force, the horizontal force is transmitted through the support frame and the piston. This ensures that the force sensor installed in the support cavity is only subjected to pressure and not to horizontal shear force, thus protecting the force sensor and ensuring its measurement accuracy. The bottom plane of the plug and the force sensor are in vertical hard contact, and the contact surfaces can be separated.

[0072] The elastic basin block 7 is installed inside the upper cavity S1 to perform the bearing and rotation functions of the support.

[0073] The spoke-type force sensor is installed in the lower cavity S2 with the center aligned.

[0074] The middle seat pull ring 6 is positioned on the lower basin ring 31 by bolts and forms a lower hook. When the lower cavity S2 is formed, the upper hook and the lower hook cooperate to form an interlocking form, which is used to resist accidental overturning moment and protect the support and internal force sensor.

[0075] Meanwhile, in this example, a through hole is formed on the lower basin ring 31, and the signal port 8 is installed in the through hole. The data transmission wire connects the signal port 8 and the data display instrument 9.

[0076] Example 3

[0077] like Figure 6 As shown, the structure of the bridge load monitoring support in this example is basically the same as that in Example 2. The difference is that this example is a unidirectional sliding force measuring support.

[0078] Specifically, a sliding member h is formed between the upper seat plate 20 and the upper plug head 51.

[0079] In this example, the sliding component h includes a sliding pair h1 and a guide bar h2. The sliding pair h1 includes a mirror stainless steel h10 located on the bottom surface of the upper seat plate 20 and a sliding plate h11 set on the upper stopper head 51.

[0080] There are two guide bars h2, which are respectively set on the bottom surface of the upper seat plate 20 on opposite sides in the sliding direction.

[0081] Meanwhile, a mirror-finished stainless steel h10 and a sliding plate h11 are installed on the upper plug head 51 and the guide strip h2 that are in contact with it. The purpose of this is to enable smooth sliding of the support.

[0082] In other words, in this example, the sliding pair consists of a sliding plate and mirror-finished stainless steel. The sliding plate is typically made of materials such as polytetrafluoroethylene (PTFE) or ultra-high molecular weight polyethylene (UHMWPE). The surface of the sliding plate usually has an oil reservoir, which is filled with lubricating silicone grease. The mirror-finished stainless steel is welded to the support components, and the sliding plate material is connected to the support components using an embedded anchoring method.

[0083] Specifically, the upper plate 20 is equipped with guide bars along the direction of the designed displacement of the support, and a sliding plate material is embedded on its inner side. The piston head sidewall is welded with mirror-finished stainless steel. This is a sliding pair set along the direction of the designed displacement of the support. Its purpose is to achieve smooth sliding of the support.

[0084] The lower plug head 52 of the middle seat 5 is located inside the lower basin ring 31 on the lower seat plate 30. When the support is subjected to a horizontal force, the horizontal force is transmitted through the outer frame of the support and the piston. This ensures that the force sensor installed in the support cavity is only subjected to pressure and not to horizontal shear force, thus protecting the force sensor and ensuring its measurement accuracy. The bottom plane of the piston head makes vertical hard contact with the force sensor, and the contact surfaces can be separated.

[0085] The lower plug 52 of the middle seat 5 also serves as a tension plate, interlocking with the inner tension plate of the lower basin ring 31 on the lower seat plate 30 to resist accidental overturning moments and protect the support and internal force sensor.

[0086] In addition to transmitting vertical force, the force sensor can also provide real-time feedback on the vertical load at the support.

[0087] The lower surface of the lower bearing plate 30 is provided with countersunk bolt through holes to anchor the force sensor inside the bearing, preventing the sensor from undergoing horizontal displacement or rotation inside the bearing during bridge operation.

[0088] The lower basin ring 31 has through holes on its side wall for routing data transmission wires.

[0089] Example 4

[0090] like Figure 7 As shown, the structure of the bridge load monitoring support in this example is basically the same as that in Example 3. The difference is that this example is a bidirectional sliding force measuring support.

[0091] The sliding pair h1 used in the bidirectional sliding force measuring support plays the role of displacement of the support.

[0092] Specifically, the sliding pair h1 consists of a sliding plate h11 and a mirror-finished stainless steel h10. The sliding plate h11 is typically made of polytetrafluoroethylene (PTFE), ultra-high molecular weight polyethylene (UHMWPE), etc. The surface of the sliding plate usually has an oil reservoir, which is filled with lubricating silicone grease. The mirror-finished stainless steel h10 is welded to the support component, and the sliding plate material is connected to the support component using an embedded anchoring method.

[0093] In this example, the mirror-finished stainless steel h10 is fixed to the bottom surface of the upper seat plate 20, and the sliding plate h11 is installed on the top surface of the upper plug head 51.

[0094] The present invention has been described in detail above, but the present invention is not limited to the embodiments described above. All equivalent changes or modifications made according to the spirit and essence of the present invention should be covered within the protection scope of the present invention.
