[0032] The following will be combined with the attached Figures 1 to 3 The embodiments of the technical solution of the present application will be described in detail. The following embodiments are only used to more clearly illustrate the technical solution of the present application, so they are only used as examples and cannot be used to limit the protection scope of the present application. In addition, the technical features involved in the various embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.
[0033] As Figure 1 Figure 0 schematically shows a support device for a bridge construction stage integrating stress and strain monitoring functions. The support device for the bridge construction stage includes: a support bottom plate 1, an adjustment mechanism 2 provided at the lower end of the support bottom plate 1, and a stress and strain monitoring unit 3 connected to the support bottom plate 1; the adjustment mechanism 2 includes a horizontal adjustment mechanism 20 and a vertical adjustment mechanism 21 provided at the upper end of the horizontal adjustment mechanism 20; wherein, the horizontal adjustment mechanism 20 includes an X-axis adjustment bench 22 and a Y-axis adjustment bench 23 provided at the upper end of the X-axis adjustment bench 22; the horizontal adjustment mechanism 20 is driven by a first hydraulic transmission mechanism 24 provided in the horizontal direction to move in the horizontal direction; the vertical adjustment mechanism 21 includes a Z-axis adjustment bench 25 and a second hydraulic transmission mechanism 26 provided on the Z-axis adjustment bench 25 in the vertical direction; the support bottom plate 1 is driven by the second hydraulic transmission mechanism 26 to move in the vertical direction.
[0034] Specifically, in this embodiment, the horizontal adjustment mechanism 20, the vertical adjustment mechanism 21, and the support bottom plate 1 are connected in the order from low to high. Among them, during the driving of the horizontal adjustment mechanism 20 by the first hydraulic transmission mechanism 24, the vertical adjustment mechanism 21 and the support bottom plate 1 connected above the horizontal adjustment mechanism 20 are driven to move in the horizontal direction to adjust the horizontal position of the bridge on the support bottom plate 1. The support bottom plate 1 is driven by the second hydraulic transmission mechanism 26 to move in the vertical direction to adjust the height of the bridge.
[0035] The stress and strain monitoring unit 3 is used to directly or indirectly monitor the two parameters of stress and strain of the bridge, so as to timely adjust the position and direction of the bridge on the support bottom plate 1 according to the parameters to ensure the safety during the bridge construction or maintenance process.
[0036] The horizontal adjustment mechanism of the present application, which includes an X-axis adjustment bench, a Y-axis adjustment bench, and a first hydraulic drive mechanism, realizes the precise horizontal adjustment of the bridge on the support base plate in the horizontal direction under the drive of the first hydraulic drive mechanism. Also, by providing a vertical adjustment mechanism including a Z-axis adjustment bench and a second hydraulic drive mechanism, the height of the bridge on the support base plate can be precisely adjusted in the vertical direction under the drive of the second hydraulic drive mechanism, effectively solving the problem that the bridge cannot be precisely adjusted in different directions and positions during bridge construction or maintenance. Moreover, by integrating a stress-strain monitoring unit, the present application enhances the real-time monitoring ability of the bridge structural health status, ensuring the safety and reliability of the construction and maintenance processes.
[0037] Figure 4 shows a structural block diagram of the stress-strain detection unit, as Figure 4 shown, in one implementation, the stress-strain monitoring unit 3 includes a measurement unit 31, a data acquisition system 32, and a controller 33; the measurement unit 31 includes at least one of a microwave measuring instrument or a laser scanner; the data acquisition system 32 is electrically connected to the measurement unit 31, the controller 33, and a strain gauge provided on the bridge respectively; the controller 33 is electrically connected to the adjustment mechanism 2.
[0038] Specifically, during the bridge construction and maintenance processes, strain gauges are generally used to detect the stress and strain data of the bridge. However, a strain gauge is a contact measurement tool, usually pasted on the surface of the bridge measurement points for measurement. In this embodiment, the measurement unit 31 includes at least one of a microwave measuring instrument or a laser scanner. The microwave measuring instrument and the laser scanner are non-contact measurement tools, which can be connected to the support base plate 1 to remotely and non-contactedly measure the minute deformation of the bridge structure without contacting the bridge surface, thereby evaluating the stress and strain of the bridge, which is particularly useful for bridge parts that are difficult to access or have a contact risk in the bridge structure. And in this embodiment, the data acquisition system 32 is electrically connected to the measurement unit 31 and the strain gauge provided on the bridge respectively, combining the contact and non-contact measurement results to obtain more comprehensive bridge stress-strain data, which helps to more accurately evaluate the actual state of the bridge.
[0039] Furthermore, in this embodiment, the data acquisition system 32, the controller 33, and the adjustment mechanism 2 are electrically connected, enabling the controller 33 to analyze the data of the stress, strain, and other key parameters of each monitoring point of the bridge uploaded by the data acquisition system 32 and issue control instructions to start the adjustment mechanism to make corresponding adjustments to the support position, angle, or force of the bridge, etc., to adapt to the actual stress state of the bridge and ensure the safety and stability of the bridge structure.
[0040] Optionally, the above electrical connection includes at least one of a wired connection or a wireless connection.
[0041] Continue to refer to Figure 1 In a further embodiment, the first hydraulic transmission mechanism 24 includes an X-axis linear guide 241 disposed on the X-axis adjustment bench 22, an X-direction slider 242 mounted on the X-axis linear guide, and a first X-axis hydraulic cylinder 243 and a second X-axis hydraulic cylinder 244 that push the X-direction slider 242 to slide in the X-axis direction.
[0042] Specifically, the X-axis adjustment bench 22 is arranged as a U-shaped bench. The X-axis linear guide 241 is connected between the two side walls of the X-axis adjustment bench 22, facilitating the lateral sliding of the X-direction slider 242 along the X-axis linear guide 241. The Y-axis adjustment bench 23 is connected to the upper end surface of the X-direction slider 242. The sliding of the X-direction slider 242 can drive the Y-axis adjustment bench 23 to move in the same direction. The first X-axis hydraulic cylinder 243 is connected between the left side wall of the X-axis adjustment bench 22 and the X-direction slider 242, and the second X-axis hydraulic cylinder 244 is connected between the right side wall of the X-axis adjustment bench 22 and the X-direction slider 242. When the X-direction slider 242 slides to the left, the piston rod of the first X-axis hydraulic cylinder 243 shortens, and at the same time, the piston rod of the second X-axis hydraulic cylinder 244 extends to the same length as the shortening of the first X-axis hydraulic cylinder 243.
[0043] Optionally, in order to improve the support strength of the X-axis adjustment bench 22, two parallel X-axis linear guides 241, two X-direction sliders 242, two first X-axis hydraulic cylinders 243 on the left side of the X-direction slider 242, and two second X-axis hydraulic cylinders 244 on the right side of the X-direction slider 242 can be arranged in the X-axis adjustment bench 22.
[0044] Continue to refer to Figure 1 In a further embodiment, the first hydraulic transmission mechanism 24 further includes a Y-axis linear guide 245 disposed above the Y-axis adjustment bench 23, a Y-direction slider 246 mounted on the Y-axis linear guide, and a first Y-axis hydraulic cylinder 247 and a second Y-axis hydraulic cylinder 248 that push the Y-direction slider 246 to slide in the Y-axis direction.
[0045] Specifically, the arrangement of the Y-axis adjustment bench 23 in this embodiment can refer to the arrangement method of the X-axis adjustment bench 22 in the previous embodiment, with the difference that the upper end surface of the Y-direction slider 246 is connected to the Z-axis adjustment bench 25, which will not be elaborated here.
[0046] Continue to refer to Figure 1 In an implementation manner of the present application, the second hydraulic transmission mechanism 26 includes a first Z-axis hydraulic cylinder 251, a second Z-axis hydraulic cylinder 252, a third Z-axis hydraulic cylinder 253, and a fourth Z-axis hydraulic cylinder 254 that are sequentially arranged at the four top corners of the upper end surface of the Z-axis adjustment bench 25.
[0047] Specifically, the first Z-axis hydraulic cylinder 251, the second Z-axis hydraulic cylinder 252, the third Z-axis hydraulic cylinder 253, and the fourth Z-axis hydraulic cylinder 254 act together on the lower end surface of the support base plate 1 through the asynchronous or synchronous telescoping of their respective piston rods, enabling the support base plate 1 to not only achieve uniform vertical movement but also be finely adjusted as needed to adapt to minor changes and uneven settlements in the bridge structure. By precisely controlling the oil pressure of each Z-axis hydraulic cylinder, smooth, graded, and multi-point support adjustment of the support base plate 1 can be achieved, thus ensuring the reliability and adaptability of the support device during the bridge construction stage.
[0048] Based on the previous embodiment, please refer to Figure 2 , in one implementation, the support base plate 1 includes a first support base plate 11 with its lower end surface connected to the first Z-axis hydraulic cylinder 251 and the second Z-axis hydraulic cylinder 252, and a second support base plate 12 with its lower end surface connected to the third Z-axis hydraulic cylinder 253 and the fourth Z-axis hydraulic cylinder 254.
[0049] In this embodiment, by providing the first support base plate 11 and the second support base plate 12 and performing graded support in a manner where two Z-axis hydraulic cylinders in the same direction control one support base plate, higher flexibility is provided for the support device during the bridge construction stage, enabling the support device during the bridge construction stage to adapt to more complex or irregular support surfaces.
[0050] Based on the previous embodiment, please refer to Figure 3 , in another implementation, the support base plate 1 includes a third support base plate 13 with its lower end surface connected to the first Z-axis hydraulic cylinder 251, a fourth support base plate 14 with its lower end surface connected to the second Z-axis hydraulic cylinder 252, a fifth support base plate 15 with its lower end surface connected to the third Z-axis hydraulic cylinder 253, and a sixth support base plate 16 with its lower end surface connected to the fourth Z-axis hydraulic cylinder 254.
[0051] In this embodiment, by providing the third support base plate 13, the fourth support base plate 14, the fifth support base plate 15, and the sixth support base plate 16 and performing multi-point support in a manner where each Z-axis hydraulic cylinder controls one support base plate, higher flexibility is provided for the support device during the bridge construction stage, enabling the support device during the bridge construction stage to adapt to more complex or irregular support surfaces.
[0052] In one implementation, right-angle baffles 4 are arranged vertically at the top corners of the upper end surface of the support base plate 1.
[0053] Specifically, the right-angled baffle 4 can serve as a limiting device for the support base plate 1 to prevent the bridge supported by the support base plate 1 from moving or shifting excessively in extreme cases. For example, when the moving speed of the first hydraulic mechanism 24 is too fast or at least one Z-axis hydraulic cylinder in the second hydraulic transmission mechanism 26 extends or retracts excessively, etc., resulting in the bridge on the support base plate 1 moving due to inertia. By setting the right-angled baffle 4 in this embodiment, the safety performance of the support device during the bridge construction stage can be enhanced.
[0054] In one implementation, the bridge construction stage support device further includes: a vehicle frame 51 disposed below the adjustment mechanism 2 and moving wheels 52 connected to the periphery of the vehicle frame 51. Specifically, the combined use of the vehicle frame 51 and the moving wheels 52 enables the bridge construction stage support device to move and position conveniently at the construction site. Optionally, the moving wheels 52 may include a locking mechanism to ensure that the bridge construction stage support device of the present application can be firmly fixed in place after positioning, preventing displacement during the bridge support process.
[0055] To prevent displacement during the bridge support process, based on the previous embodiment, continue to refer to Figure 1 , in one implementation, the bridge construction stage support device further includes: a parking support rod 6 connected to the lower part of the horizontal adjustment mechanism 20. Specifically, the parking support rod 6 is used for rapid deployment in the parking state to provide a supporting force in the vertical or horizontal direction for the bridge construction stage support device. Optionally, the parking support rod 6 can be telescopic, so that the operator can adjust it according to the actual support height or length requirements to achieve a flexible support configuration.
[0056] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
