Description

Technical Field

[0001] This utility model relates to the field of bridge construction technology, specifically to a monitoring device for bridge construction. Background Technology

[0002] During bridge construction, deformation monitoring is required. There are generally three monitoring methods: first, geodetic control surveying, also known as conventional ground surveying, which is the main means of deformation observation; second, special surveying methods, including tilt measurement and laser collimation measurement; and third, ground stereophotogrammetry.

[0003] The existing monitoring equipment and its reference detection points are subject to slight changes due to environmental influences, which can affect the accuracy of the data measured by the equipment and mislead monitoring personnel. This necessitates frequent manual calibration to ensure accuracy, which places a burden on monitoring personnel. Furthermore, the construction process of multiple devices is easily affected by the work of installation workers, resulting in different reference errors between devices, which ultimately affects the accuracy of monitoring and jeopardizes the normal construction of the bridge.

[0004] To overcome the aforementioned deficiencies, existing technology (Chinese patent publication number: CN112985287B, publication date: 2021-10-26) discloses a bridge construction deformation monitoring device, belonging to the field of bridge construction technology. It includes a detection device, a laser monitoring device, an upper support platform, a lower support platform, an adjustment mechanism, a liquid level control mechanism, a lifting mechanism, a laser detection mechanism, and a laser alignment mechanism. This invention provides a bridge construction deformation monitoring device that selects multiple reference surfaces. It detects changes in the detection device associated with each reference surface using laser alignment, selects the reference surface with the smallest range of change, divides the reference surface into multiple regions, and embeds a liquid level control mechanism in each region. Through the principle of liquid interconnection, the liquid level control mechanism pushes the monitoring device to adjust its position accordingly when multiple regions change, ensuring the monitoring device maintains a state of minimal change. The monitoring device automatically straightens itself through gravity straightening and uses laser alignment, making installation between multiple devices easier and avoiding excessive errors.

[0005] While the above design can solve the aforementioned problems, the display design for when the bridge experiences downward settlement is not direct enough, which can lead to deviations in the bridge detection results, hinder the recording of detection results, and reduce the efficiency of use. At the same time, when the bridge tilts, the existing design lacks sufficient warning features and cannot accurately and quickly respond to changes in the bridge, resulting in insufficient intelligence in the use of the equipment. Utility Model Content

[0006] The purpose of this utility model is to provide a monitoring device for bridge construction, in order to solve the problems mentioned in the background art, which are that the display design when the bridge is sinking is not direct enough, which leads to deviations in the detection results of the bridge, is not conducive to the recording of detection results and reduces the efficiency of use. At the same time, when the bridge tilts, the existing design is not good enough to respond to the changes in the bridge accurately and quickly, which makes the device less intelligent.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a monitoring device for bridge construction, comprising a stable support base, a rotating connecting plate mounted above the stable support base, and a sliding mechanism for moving a mating display rod downwards inside the rotating connecting plate. The sliding mechanism includes a hollow mating frame, which is fixedly mounted on the upper surface of the rotating connecting plate. The mating display rod is nested inside the hollow mating frame, and inclined connecting rods are mounted on the left and right sides of the mating display rod. A pressing and abutting frame is mounted on the inner surface of the stable support base, and an elastic abutting mechanism for rotating an inwardly recessed mating plate is mounted inside the pressing and abutting frame.

[0008] Furthermore, the elastic abutment mechanism includes a fixed rotating frame, which is fixedly installed on the lower surface of the rotating connecting plate. An integral rotating rod is installed on the inner surface of the stable support base, and the fixed rotating frame is rotatably installed on the outer surface of the integral rotating rod.

[0009] Furthermore, a compression abutment frame is installed on the inner surface of the stable support base, and a start / stop abutment rod is installed inside the compression abutment frame. A compression return spring is installed on the outer surface of the start / stop abutment rod, and the end of the compression return spring abuts against the side of the compression abutment frame.

[0010] Furthermore, the end of the inclined connecting rod is slidably mounted on the upper surface of the rotating connecting plate, and a contraction and extension spring is installed on the inner surface of the inclined connecting rod. The other end of the contraction and extension spring is fixedly mounted on the side of the hollow fitting frame, and a vertical sliding frame is installed on the back of the hollow fitting frame.

[0011] Furthermore, a downward pressing abutment rod is installed inside the vertical sliding frame, and the end of the downward pressing abutment rod's movement trajectory abuts against the top of the fitting display rod. A scale is installed on the outer surface of the hollow fitting frame, and the outer surface of the fitting display rod is in contact with the side of the scale.

[0012] Furthermore, the top of the inclined connecting rod is rotatably mounted on the left and right sides of the embedded display rod, and two sets of inclined connecting rods and retractable extension springs are symmetrically installed about the center point of the hollow embedded frame. The inner surface of the vertical sliding frame contacts the outer surface of the pressing contact rod to form a sliding structure, and the inner surface of the inclined connecting rod contacts the top of the retractable extension spring to form an elastic structure.

[0013] Furthermore, an indicator light is installed on the upper surface of the stable support base, and the movement trajectory of the start / stop contact rod abuts against the switch of the indicator light. A semi-circular swing rod is installed on the lower surface of the rotating connecting plate, and the rotation trajectory of the semi-circular swing rod abuts against the end of the start / stop contact rod.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: When the bridge settles, the bridge will directly press down the mating display rod vertically through the downward pressing abutment rod. The movement of the mating display rod will continuously keep in contact with the scale, so that the descent dimension can be accurately recorded. In addition, the cooperation between the inclined connecting rod and the contraction and extension spring provides overall buffering for the device. This design makes the display design when the bridge settles downward more direct, will not cause deviation in the bridge detection results, facilitates the recording of detection results and improves the efficiency of use.

[0015] Furthermore, during installation, the concave fitting plate is kept in close contact with the bridge's support column. When the column deviates, the hollow fitting frame will rotate the semi-circular swing rod, causing the start / stop contact rod to slide accordingly and directly activating the warning light. This design makes the reminder effect better, enabling accurate and rapid alerts of changes to the bridge and improving the intelligence of the equipment.

[0016] Furthermore, the rotating connecting plate is designed with multiple sets of flexible support components below the corresponding installation position inside the stable support base, which ensures improved placement stability of the hollow fitting frame and allows the equipment to achieve better stability.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1: Please refer to Figure 1 , Figure 3 and Figure 4 This utility model provides the following technical solution: a monitoring device for bridge construction, including a stable support base 1, a rotating connecting plate 2 installed above the stable support base 1, and a sliding mechanism for moving a display rod 7 downwards installed inside the rotating connecting plate 2. The sliding mechanism includes a hollow fitting frame 4, and the hollow fitting frame 4 is fixedly installed on the upper surface of the rotating connecting plate 2. Figure 1 As shown, the embedded display rod 7 is nested inside the hollow embedded frame 4, and inclined connecting rods 3 are installed on the left and right sides of the embedded display rod 7. The inner surface of the stable support base 1 is equipped with a pressing contact frame 15, and the inside of the pressing contact frame 15 is equipped with an elastic contact mechanism that rotates the concave bonding plate 11.

[0026] like Figure 1 , Figure 3 and Figure 4 The technical solution shown, in order to solve the problem of inconvenient manual maintenance in case of malfunction, discloses that: the end of the inclined connecting rod 3 is slidably mounted on the upper surface of the rotating connecting plate 2, and a contraction and extension spring 6 is installed on the inner surface of the inclined connecting rod 3. The other end of the contraction and extension spring 6 is fixedly mounted on the side of the hollow fitting frame 4, and a vertical sliding frame 8 is installed on the back of the hollow fitting frame 4. A downward pressing contact rod 9 is installed inside the vertical sliding frame 8, and the end of the moving trajectory of the downward pressing contact rod 9 abuts against the top of the fitting display rod 7, such as... Figure 3 As shown, a scale 5 is installed on the outer surface of the hollow fitting frame 4, and the outer surface of the fitting display rod 7 is in contact with the side of the scale 5. The top of the inclined connecting rod 3 is rotatably installed on the left and right sides of the fitting display rod 7. Two sets of inclined connecting rods 3 and retraction extension springs 6 are symmetrically installed about the center point of the hollow fitting frame 4. The inner surface of the vertical sliding frame 8 contacts the outer surface of the downward pressing contact rod 9 to form a sliding structure, and the inner surface of the inclined connecting rod 3 contacts the top of the retraction extension spring 6 to form an elastic structure.

[0027] When monitoring and recording the settlement depth of a bridge is required, the stabilizing support 1 is placed entirely around the bridge pier. During settlement, the bridge pier slides downwards and simultaneously presses against the top of the downward-pressing contact rod 9, causing it to move. The interlocking display rod 7 slides downwards due to this pressing motion. Simultaneously, the sliding of the interlocking display rod 7 adheres to the inner surface of the hollow interlocking frame 4, resulting in a stable nesting motion and improved equipment stability. Furthermore, the sliding of the interlocking display rod 7 ensures that its lower end remains in contact with the scale 5 fixedly installed on the outer surface of the hollow interlocking frame 4, providing a clear and intuitive display of the settlement depth for easy data analysis. According to the records, during the downward movement of the display rod 7, the inclined connecting rods 3, which are rotatably mounted on the left and right sides, will be driven to move downward accordingly. Since the end of the inclined connecting rod 3 is slidably mounted on the upper surface of the rotating connecting plate 2, the end of the inclined connecting rod 3 will extend outward accordingly. As the inclined connecting rod 3 slides outward, the contraction and extension spring 6, which is fixedly mounted on the inner surface of the inclined connecting rod 3, will be extended outward accordingly. Since the other end of the contraction and extension spring 6 is fixedly mounted on the side of the hollow fitting frame 4, the cooperation between the inclined connecting rod 3 and the contraction and extension spring 6 makes the whole equipment vertically buffered and improves the stability of the equipment.

[0028] Example 2: Figure 2 , Figure 5 and Figure 6 The technical solution shown, in order to solve the problem of inconvenient manual maintenance in case of malfunction, discloses: an elastic abutment mechanism including a fixed rotating frame 13, which is fixedly installed on the lower surface of the rotating connecting plate 2; an integral rotating rod 14 is installed on the inner surface of the stable support 1; and the fixed rotating frame 13 is rotatably installed on the outer surface of the integral rotating rod 14. Figure 6As shown, a compression contact frame 15 is installed on the inner surface of the stable support base 1, and a start / stop contact rod 16 is installed inside the compression contact frame 15. A compression return spring 17 is installed on the outer surface of the start / stop contact rod 16, and the end of the compression return spring 17 abuts against the side of the compression contact frame 15. An indicator alarm light 12 is installed on the upper surface of the stable support base 1, and the movement trajectory of the start / stop contact rod 16 abuts against the switch of the indicator alarm light 12. A semi-circular swing rod 10 is installed on the lower surface of the rotating connecting plate 2, and the rotation trajectory of the semi-circular swing rod 10 abuts against the end of the start / stop contact rod 16.

[0029] During the overall installation of the equipment, the inner surface of the concave fitting plate 11, which is rotatably mounted on the back of the hollow fitting frame 4, is kept in close vertical contact with the outer surface of the bridge column. When the bridge column tilts left or right, it will push the hollow fitting frame 4 back and forth in a corresponding manner through the concave fitting plate 11. Since the fixed rotating frame 13 is fixedly mounted on the lower surface of the rotating connecting plate 2, and the fixed rotating frame 13 is rotatably mounted on the outer surface of the integrated rotating rod 14, the entire hollow fitting frame 4 will rotate stably in a circular motion along the outside of the integrated rotating rod 14. Figure 5 As shown, the two ends of the integrated rotating rod 14 are fixedly installed on the inner surface of the stable support base 1. Therefore, the rotating connecting plate 2 and the fixed rotating frame 13 will swing stably along the inside of the stable support base 1. During the swinging process of the rotating connecting plate 2, the semi-circular swing rod 10 fixedly installed on the lower surface will swing synchronously. The swinging of the semi-circular swing rod 10 will correspondingly abut against the end of the start-stop abutment rod 16 and push it outward. The start-stop abutment rod 16 will slide outward along the inside of the compression abutment frame 15 fixedly installed inside the stable support base 1. During the sliding process, the front end of the start-stop abutment rod 16 will abut against the indicator alarm light 12 and trigger it to start the alarm. The compression return spring 17 nested on the outer surface of the start-stop abutment rod 16 will contact the compression abutment frame 15 and contract after mutual contact. After the contact is broken, the compression return spring 17 will make the start-stop abutment rod 16 quickly complete the reset, making the alarm function of the device more sensitive and faster.
