Description

Technical Field

[0001] This invention relates to the field of engineering surveying technology, and in particular to bridge deformation monitoring equipment installed in subway tunnels passing under high-speed railway bridges. Background Technology

[0002] With economic development and the continuous acceleration of urban three-dimensional construction, many elevated bridges and tunnel projects have emerged. Many tunnel projects inevitably face the problem of crossing existing bridges. Crossing under a bridge can affect the foundation, potentially causing foundation subsidence, pier drop, and bridge deformation. Therefore, it is necessary to monitor the bridge's condition in real time during such construction.

[0003] The existing monitoring method is to set up monitoring points on the bridge body and monitor the deformation of the bridge during construction and use. For a specific example, see the bridge deformation monitoring method in patent application number CN201811601704.9.

[0004] By setting the benchmark points for measurement inside or outside the girder box girder, it is possible to measure the irregular deformation caused by uneven settlement at different locations of the bridge. However, for projects such as underpass tunnels, if no monitoring points are pre-set before the bridge construction, the needs for temporary monitoring cannot be met. Moreover, due to the characteristics of underpass tunnel projects, the piers directly above the tunnel and the bridge may settle synchronously, causing the benchmark points and monitoring points to drop synchronously, making it inconvenient to monitor the displacement of the monitoring points. This results in all the monitoring benchmarks set inside or on the piers becoming unusable or producing incorrect monitoring data, creating construction safety hazards. Summary of the Invention

[0022] In order to make the purpose, technical scheme and advantages of the present application more clear, the present application will be further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the present application and do not limit the present application.

[0023] Example 1

[0024] As shown in Figures 1-6 , the subway tunnel underpass high-speed rail bridge engineering bridge deformation monitoring installation equipment provided by the present application comprises a square tube 1 and a square rod 2, the square rod 2 is slidingly connected in the square tube 1, one end of the square tube 1 is fixedly connected with a blind plate, a first spring is fixedly connected between the blind plate and the extending end of the square rod 2, the square rod 2 is fixedly connected with an arc-shaped guide rail 3 at the end away from the square tube 1, a moving seat 4 is slidingly connected on the upper side of the arc-shaped guide rail 3, a level 5 is arranged on the upper side of the moving seat 4, one support rod 6 is fixedly connected at each end of the inner arc surface of the arc-shaped guide rail 3, a support wheel 61 is rotatably connected at the end of the support rod 6, a driving motor 62 is fixedly connected on one side of the support rod 6, and the main shaft of the driving motor 62 is fixedly connected with the support wheel 61.

[0025] A suspension device 7 is arranged on the square tube 1 or the square rod 2, so that when the arc-shaped guide rail 3 is raised in place, a suspension support is formed by the suspension device 7, avoiding the entire device from sliding down due to power failure of the driving motor 62, and improving safety.

[0026] An installation hole is arranged at one end of the arc-shaped guide rail 3, a tie is fixedly connected in the installation holes of the two arc-shaped guide rails 3, and the two arc-shaped guide rails 3 can be tied together to form a whole, avoiding the square tube 1 and the square rod 2 on one side from being too heavy, causing insufficient support force of the two support wheels 61 of the arc-shaped guide rail 3, and avoiding falling.

[0027] When using this invention, monitoring points are set up on the bridge body of the high-speed railway bridge, and monitoring points can be set on the side of the arc-shaped guide rail 3. The level instrument 5 remotely monitors the elevation of the monitoring points, thereby obtaining the deformation of the bridge body. The subway tunnel of this invention is set on the piers of the bridge body above it. At the same time, multiple installation devices of this invention can be set on the piers at a distance. Taking advantage of the fact that the piers at a distance do not settle, the position of the level instrument 5 can be calibrated one by one, thereby avoiding the monitoring inaccuracy caused by the benchmark change of the level instrument 5 and ensuring the accuracy of the monitoring.

[0028] During installation, two hydraulic jacks are used to widen the gap between the two arc-shaped guide rails 3, allowing them to enter the pier. After the hydraulic jacks are removed, the support wheel 61 on the inner arc surface of the arc-shaped guide rail 3 is supported on the side of the pier by the rebound action of the first spring. Then, the drive motor 62 drives the support wheel 61 to climb on the pier, raising the arc-shaped guide rail 3 to a high position with an unobstructed field of view. Guided by the arc-shaped guide rail 3, the level instrument 5 can be moved to different positions on the pier to monitor the bridge between the two piers. The level instrument 5 can also be moved to the side of the pier to monitor the side of the bridge above the adjacent pier that is easily obstructed, thus facilitating a comprehensive inspection of the bridge deformation from different positions and ensuring sufficient monitoring coverage.

[0029] The upper side of the arc-shaped guide rail 3 is provided with a guide groove 31. The cross section of the movable seat 4 is inverted "T" shape. The movable seat 4 is fixedly connected to the walking motor 41 on one side. The main shaft of the walking motor 41 is fixedly connected to the walking wheel 42. The walking wheel 42 presses against the upper side of the arc-shaped guide rail 3.

[0030] The movable seat 4 is internally fixedly connected to a steering motor, the main shaft of which is fixedly connected to a six-degree-of-freedom platform 43. The level 5 is fixedly connected to the upper side of the six-degree-of-freedom platform 43. The angle and orientation of the level 5 are electrically adjustable to adapt to measuring the monitoring point at different positions.

[0031] Example 2

[0032] like Figures 1-6 As shown, a suspension device 7 is disclosed in the embodiment. The suspension device 7 includes a sliding frame 71, which is slidably connected to a square tube 1 or a square rod 2. A vertical rod 72 is fixedly connected to the upper side of the sliding frame 71. A horizontal rod 73 is slidably connected to the upper end of the vertical rod 72. A slope 74 is provided on the upper side of one end of the horizontal rod 73. A vertical plate 75 is fixedly connected to the other end of the horizontal rod 73. A round rod 76 is fixedly connected to the lower end of the vertical plate 75. The vertical rod 72 is provided with a round hole. The round rod 76 passes through the round hole and is slidably connected. The round rod 76 is provided with a boss 77. A support spring 78 is fixedly connected between the boss 77 and the vertical rod 72.

[0033] The round rod 76 is rotatably connected with the circular column 79 at the end away from the vertical rod 72, the round rod 76 is provided with a insertion hole 761, the vertical rod 72 is provided with a sliding hole 762 on one side, the sliding hole 762 is communicated with the round hole, the insertion rod 763 is slidably connected in the sliding hole 762, the insertion rod 763 is correspondingly arranged with the insertion hole 761, the outer end of the insertion rod 763 is fixedly connected with the baffle 764, and the baffle 764 is fixedly connected with the vertical rod 72 and the tension spring 765.

[0034] When the suspension device 7 is in use, the sliding frame 71 is adjusted on the square rod 2 to avoid the support frame 20 of the existing pier support platform 10, and is lifted through the arc-shaped guide rail 3, when the inclined surface 74 of the cross rod 73 contacts the edge of the support platform 10, the cross rod 73 is caused to slide and avoid through the action of the inclined surface 74, and when the cross rod 73 is higher than the support platform 10, the cross rod 73 is reset through the rebound force of the support spring 78, and the cross rod 73 is arranged on the upper side of the support platform 10, so that the device can stably stay at a high place through the consecutive actions in the climbing process.

[0035] After the tunnel is completed and the deformation of the bridge does not need to be monitored, the support wheel 61 is further lifted through the driving motor 62, so that the circular column 79 acts on the inclined beam of the support frame 20, with the continuous lifting of the device, the circular column 79 pushes away the round rod 76, correspondingly, the cross rod 73 is away from the support platform 10, and finally the insertion hole 761 on the round rod 76 is inserted into the round hole of the vertical rod 72, and is coaxial with the insertion rod 763, the insertion rod 763 on the side of the round rod 76 is pulled out and inserted into the insertion hole 761 through the tension spring 765, the round rod 76 is locked on the vertical rod 72, and then during the whole descending process of the device, the round rod 76 remains relatively stationary, so that the cross rod 73 is away from the support platform 10, and the device can stably descend to the ground, so that the device can be conveniently installed and disassembled, and can be quickly monitored in different projects.

[0036] When there is no support platform 10 on the pier, the top surface and the slope surface on the upper end of the pier can play the same role, so that the device has a wide application range and can be installed on piers of different sizes, and the deformation of bridges of different specifications can be monitored.

[0037] Although the embodiments of the present application have been shown and described, it should be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirits of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
