Description

Technical Field

[0001] This utility model belongs to the field of monitoring equipment technology, and more specifically, it relates to a monitoring device for the jacking construction of a frame bridge. Background Technology

[0002] In areas where highways intersect with existing railways, to ensure uninterrupted railway operations, a frame bridge with a U-shaped three-dimensional frame structure is used as an underpass. The constructed frame bridge allows vehicles to pass through its interior, while the roof supports the normal operation of railway traffic.

[0003] During the jacking construction of existing frame bridges, it is necessary to monitor the structural stress points of the bridge during the construction process to ensure the safety of construction and the safety of use after completion. Current construction monitoring relies on manual on-site duty, especially during the jacking operation, which requires technicians to be continuously exposed to the dangerous construction area, increasing labor costs and posing significant safety hazards. Utility Model Content

[0004] This utility model provides a monitoring device for the jacking construction of a frame bridge, which can monitor the frame bridge in all directions without blind spots by moving the monitoring components in the lateral and longitudinal directions. No manual on-site duty is required, which not only saves manpower but also eliminates safety hazards.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A monitoring device for the jacking construction of a frame bridge is provided, comprising two sets of hook seats, two tracks, two sets of traveling components, and a monitoring component. The two sets of hook seats are respectively disposed on two opposite inner sidewalls of the frame bridge, and each hook seat has an upwardly bent hook. The two tracks are respectively disposed in one-to-one correspondence with the two sets of hook seats, and each track has a hook sleeve that engages with the hook. The tracks extend along the direction of the frame bridge. The two sets of traveling components are respectively in one-to-one rolling engagement with the two tracks, and the two sets of traveling components are connected by a mounting frame. The monitoring component is slidably connected to the mounting frame along the interval direction of the two tracks for monitoring the frame bridge.

[0006] In one possible implementation, the track has an upward-opening travel groove, and the travel assembly includes two drive wheels spaced apart along the track. The drive wheels are rotatably connected to the end of the mounting frame and roll in cooperation with the travel groove along the track. A drive member for driving the drive wheel is connected to one side of the drive wheel.

[0007] In one possible implementation, the end of the mounting bracket is provided with a guide member, and the end of the guide member near the track is rotatably connected to a guide wheel that abuts against the inner wall of the track and is in rolling engagement.

[0008] In some embodiments, the guide includes a receiving cylinder, an elastic element, and a clamping platform. The receiving cylinder is connected to the end of the mounting bracket and has its opening facing the track. The elastic element is connected to the inner bottom wall of the receiving cylinder and extends toward the track. The clamping platform is connected to the extended end of the elastic element and is slidably connected to the receiving cylinder. A guide wheel is rotatably connected to the end of the clamping platform near the track.

[0009] In some embodiments, the end of the clamping platform away from the track is connected to a guide post that extends away from the track and penetrates the bottom wall of the receiving cylinder, and an elastic element is sleeved on the outer periphery of the guide post.

[0010] In some embodiments, two guide wheels are spaced apart along the vertical direction.

[0011] In one possible implementation, the mounting frame is provided with a slide bar extending along the interval direction of the two tracks, the monitoring component is slidably sleeved on the outer periphery of the slide bar and slidably connected to the slide bar, and the mounting frame is provided with a sliding drive assembly for driving the monitoring component.

[0012] In some embodiments, the sliding drive assembly includes a lead screw and a drive motor. The lead screw is rotatably connected to the mounting bracket along the interval of the two tracks and is threadedly connected to the monitoring element. The drive motor is connected to one end of the lead screw.

[0013] In one possible implementation, the hook seat is connected to the frame bridge via a connector.

[0014] In one possible implementation, each set of hook seats includes several hook seats spaced apart along the direction of the frame bridge.

[0015] Compared with the prior art, the frame bridge jacking construction monitoring equipment provided in this embodiment forms a stable suspension system through the cooperation of hooks and rail hooks, ensuring that the rail is firmly installed and the force is balanced, avoiding rail deviation or detachment caused by construction vibration. Two sets of traveling components are placed on two rails respectively, and the two sets of traveling components are rigidly connected by the mounting frame and roll synchronously along the rails, ensuring the synchronicity and stability of the monitoring component when it moves, reducing the risk of equipment tilting or jamming due to uneven resistance on one side.

[0027] Please see Figures 1 to 6 The monitoring equipment for jacking construction of a frame bridge provided by this utility model is described below. The monitoring equipment includes two sets of hook seats 10, two tracks 20, two sets of traveling components 30, and a monitoring element 50. The two sets of hook seats 10 are respectively disposed on two opposite inner sidewalls of the frame bridge 1, and each hook seat 10 has an upwardly bent hook 11. The two tracks 20 are respectively disposed in a one-to-one correspondence with the two sets of hook seats 10, and each track 20 has a hook sleeve 21 that engages with the hook 11. The tracks 20 extend along the direction of the frame bridge 1. The two sets of traveling components 30 are respectively in a rolling engagement with the two tracks 20, and the two sets of traveling components 30 are connected by a mounting frame 40. The monitoring element 50 is slidably connected to the mounting frame 40 along the interval direction of the two tracks 20, and is used to monitor the frame bridge 1.

[0028] Furthermore, the hook sleeve 21 is located on the side of the track 20 near the inner wall of the frame bridge 1, and the hook sleeve 21 is provided with a through cavity for accommodating the hook 11 in the vertical direction.

[0029] Furthermore, track 20 is made of lightweight materials.

[0030] This application provides a monitoring device for the jacking construction of a frame bridge. In actual use, the hook seat 10 is first installed at a predetermined position on the frame bridge 1, and two rails 20 are hooked onto the corresponding hook seats 10. The hook 11 and the hook sleeve 21 of the rail 20 cooperate to form a stable suspension system, ensuring that the rail 20 is firmly installed and the force is balanced, avoiding the deviation or fall of the rail 20 caused by construction vibration. Two sets of walking components 30 are respectively placed on the two rails 20. The two sets of walking components 30 are rigidly connected by the mounting frame 40 and roll synchronously along the rails 20, ensuring the synchronicity and stability of the movement of the monitoring component 50, reducing the risk of equipment tilting or jamming due to uneven resistance on one side. The monitoring component 50 can slide along the interval direction of the two rails 20. Combined with the longitudinal movement of the walking components 30, the monitoring component 50 can monitor the frame bridge 1 in all directions without blind spots, without the need for manual on-site duty, which not only saves manpower but also eliminates safety hazards.

[0031] Compared with the prior art, the frame bridge jacking construction monitoring equipment provided in this embodiment forms a stable suspension system through the cooperation of the hook 11 and the hook sleeve 21 of the track 20, ensuring that the track 20 is firmly installed and the force is balanced, avoiding the deviation or fall of the track 20 caused by construction vibration. The two sets of walking components 30 are respectively placed on the two tracks 20. The two sets of walking components 30 are rigidly connected by the mounting frame 40 and roll synchronously along the track 20, ensuring the synchronicity and stability of the movement of the monitoring component 50, reducing the risk of equipment tilting or jamming due to uneven resistance on one side. The monitoring component 50 can slide along the interval direction of the two tracks 20. Combined with the longitudinal movement of the walking components 30, the monitoring component 50 can monitor the frame bridge 1 in all directions without blind spots, without the need for manual on-site duty, which not only saves manpower, but also eliminates safety hazards.

[0032] In one possible implementation, the aforementioned orbital 20 adopts the following... Figures 2 to 5 The structure shown is described in the following document. Figures 2 to 5 The track 20 has an upward-opening travel groove 22. The travel assembly 30 includes two drive wheels 31 spaced apart along the track 20. The drive wheels 31 are rotatably connected to the end of the mounting frame 40 and roll in cooperation with the travel groove 22 along the track 20. A drive member 32 for driving the drive wheel 31 is connected to one side of the drive wheel 31.

[0033] Specifically, the upward-opening travel groove 22 of the track 20 forms a closed guide channel, with the drive wheel 31 embedded in the groove and rolling, effectively limiting the lateral displacement of the travel assembly 30 and avoiding the risk of derailment due to construction vibration, making it particularly suitable for high-vibration environments. The two drive wheels 31 are spaced apart along the track 20, distributing the equipment weight and driving force, reducing single-point contact pressure, decreasing local wear on the track 20, and extending its service life. The drive component 32 (such as a servo motor or hydraulic motor) is directly connected to the drive wheel 31, providing controllable power output, supporting speed change, start / stop, and reverse movement, meeting the monitoring needs of different speed ranges during jacking construction, and facilitating remote control.

[0034] In one possible implementation, the aforementioned mounting bracket 40 adopts, as shown in... Figures 2 to 5 The structure shown is described in the following document. Figures 2 to 5 The end of the mounting bracket 40 is provided with a guide member 60, and the end of the guide member 60 near the track 20 is rotatably connected to a guide wheel 61 that abuts against the inner side wall of the track 20 and is in rolling cooperation.

[0035] Specifically, the guide wheel 61 rolls against the inner wall of the track 20, correcting the deviation of the traveling direction of the walking component 30 in real time, ensuring that the monitoring component 50 moves in a straight line along the predetermined trajectory, avoiding path deviation caused by installation errors or deformation of the track 20, and improving data positioning accuracy. The guide wheel 61 transfers the lateral load of the walking component 30 to the inner wall of the track 20, reducing frictional loss between the drive wheel 31 and the side wall of the walking groove 22, reducing running resistance, improving driving efficiency and reducing energy consumption.

[0036] In some embodiments, see Figure 2 , Figure 3 , Figure 5 and Figure 6 The guide member 60 includes a receiving cylinder 62, an elastic member 63, and a clamping platform 64. The receiving cylinder 62 is connected to the end of the mounting bracket 40 and its opening faces the track 20. The elastic member 63 is connected to the inner bottom wall of the receiving cylinder 62 and extends toward the track 20. The clamping platform 64 is connected to the extended end of the elastic member 63 and is slidably connected to the receiving cylinder 62. The guide wheel 61 is rotatably connected to one end of the clamping platform 64 near the track 20.

[0037] Specifically, the elastic element 63 (such as a spring or rubber damper) applies continuous pressure through the clamping platform 64, ensuring that the guide wheel 61 remains firmly against the inner wall of the track 20. Even if the track 20 experiences slight deformation or vibration due to construction loads, stable contact is maintained, preventing the guide wheel 61 from detaching and causing guidance failure. The elastic element 63 absorbs impact loads generated during construction (such as instantaneous vibrations of the jacking equipment), reducing the vibration amplitude transmitted to the monitoring element 50, protecting the monitoring element 50 from high-frequency vibration interference, and ensuring data accuracy. Furthermore, the receiving cylinder 62 and the clamping platform 64 are connected by a separate sliding connection, facilitating the disassembly and replacement of worn guide wheels 61 or elastic elements 63, reducing downtime for maintenance, and improving equipment availability.

[0038] In some embodiments, see Figure 2 , Figure 3 , Figure 5 and Figure 6 The end of the clamping platform 64 away from the track 20 is connected to a guide post 65 that extends away from the track 20 and penetrates the bottom wall of the receiving cylinder 62. The elastic element 63 is sleeved on the outer periphery of the guide post 65.

[0039] Specifically, the guide post 65 penetrates the bottom wall of the receiving cylinder 62, restricting the clamping platform 64 to move only along the axial direction, preventing radial swaying when the elastic element 63 is compressed, and ensuring that the guide wheel 61 is always aligned with the inner wall of the track 20, thus improving guiding accuracy. The elastic element 63 is sleeved on the outer periphery of the guide post 65 to prevent plastic deformation or breakage due to lateral torsion or shear force, extending the service life of the elastic element 63. By adjusting the stiffness of the elastic element 63, the clamping force of the guide wheel 61 on the track 20 can be flexibly set to adapt to different track 20 materials (such as steel rails, aluminum rails) or construction environment requirements.

[0040] In some embodiments, see Figure 2 and Figure 5 Two guide wheels 61 are spaced apart along the vertical direction.

[0041] Specifically, the two guide wheels 61 share the lateral load, reducing the contact stress of a single guide wheel 61, decreasing the wear rate, and increasing system redundancy. Even if a single guide wheel 61 fails, the basic guiding function can still be maintained. The distance between the upper and lower guide wheels 61 forms a lever arm to resist the torsional torque generated by uneven driving force or external interference in the walking assembly 30, maintaining the overall stability of the equipment.

[0042] In some embodiments, see Figure 5 The mounting bracket 40 is provided with a slide rod 41 extending along the interval direction of the two tracks 20. The monitoring element 50 is slidably sleeved on the outer periphery of the slide rod 41 and slidably connected to the slide rod 41. The mounting bracket 40 is provided with a sliding drive assembly 70 for driving the monitoring element 50.

[0043] Specifically, the slide bar 41 extends along the interval of the track 20, allowing the monitoring component 50 to slide laterally. Combined with longitudinal movement, it forms a two-dimensional monitoring grid, enabling comprehensive data collection without manual intervention and significantly improving monitoring efficiency. The slide bar 41, as a sliding reference axis, provides high-rigidity support for the monitoring component 50, avoiding positioning errors caused by deflection during lateral movement. This is particularly suitable for the high-precision monitoring requirements of long-span frame bridges 1.

[0044] Optionally, the sliding drive assembly 70 is an electric push rod mounted on the mounting bracket 40, which extends along the extension direction of the two rails 20, and the telescopic end of the electric push rod is connected to the monitoring component 50.

[0045] Optionally, the sliding drive assembly 70 includes a lead screw 71 and a drive motor 72. The lead screw 71 is rotatably connected to the mounting bracket 40 along the interval direction of the two rails 20 and is threadedly connected to the monitoring element 50. The drive motor 72 is connected to one end of the lead screw 71.

[0046] In some embodiments, see Figure 5 The sliding drive assembly 70 includes a lead screw 71 and a drive motor 72. The lead screw 71 is rotatably connected to the mounting bracket 40 along the interval direction of the two rails 20 and is threadedly connected to the monitoring element 50. The drive motor 72 is connected to one end of the lead screw 71.

[0047] Specifically, the lead screw 71 transmission has micron-level repeatability, ensuring that the position of the monitoring element 50 is precisely controllable during lateral scanning, making it suitable for scenarios requiring high-resolution data acquisition. The mechanical self-locking characteristic of the lead screw 71 can fix the position of the monitoring element 50 when power is off or the machine is stopped, preventing accidental displacement caused by gravity or vibration.

[0048] In one possible implementation, the hook holder 10 adopts the following... Figures 1 to 4 The structure shown is described in the following document. Figures 1 to 4 The hook seat 10 is connected to the frame bridge 1 via the connector 12.

[0049] Specifically, the connector 12 is an expansion bolt. The expansion bolt forms a strong engagement with the concrete or steel structure of the frame bridge 1 through the principle of mechanical expansion. Its tapered sleeve expands radially when tightened, generating extremely high radial pressure, which gives the connection between the hook seat 10 and the bridge body excellent pull-out resistance.

[0050] In one possible implementation, the hook holder 10 adopts the following... Figure 1 and Figure 3 The structure shown is described in the following document. Figure 1 and Figure 3 Each set of hook seats 10 includes several hook seats 10 spaced apart along the direction of the frame bridge 1.

[0051] Specifically, multiple hook supports 10 are spaced apart along the direction of the frame bridge 1, forming multi-point suspension support to distribute the weight of the track 20 and equipment, preventing deformation or detachment of the hook supports 10 due to single-point overload, which is especially suitable for long-distance jacking construction. The densely distributed hook supports 10 reduce the span of the track 20, reduce the deflection deformation of the track 20 due to its own weight or load, ensure the straight running trajectory of the traveling component 30, and reduce monitoring data errors. If a single hook support 10 is damaged due to accident, adjacent hook supports 10 can still provide support, ensuring basic equipment operation and improving system reliability.

[0052] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
