Description

Technical Field

[0001] The present application relates to the field of settlement observation technology, and specifically to a settlement observation device for a pedestrian bridge and a method for using the same. Background Art

[0002] In the field of bridge engineering, especially in the construction and maintenance of pedestrian bridges, settlement observation is a vital task. Settlement observation aims to regularly monitor the vertical deformation of the bridge structure and promptly detect potential safety hazards to ensure the stability and safety of the bridge, thereby protecting the safety of pedestrians.

[0003] Traditional settlement observation methods often rely on manual operation and simple measuring tools, such as using a level in combination with a ruler to measure height differences. However, these methods have many limitations in practical applications. Currently available devices perform poorly in terms of support stability and adjustment flexibility, making it difficult to meet complex and changing measurement needs. Unstable support may cause the device to shake or shift during the measurement process, thereby affecting the accuracy of the measurement results; and inflexible adjustment may limit the measurement angle and height, making it difficult to conduct observations comprehensively and accurately. Therefore, a settlement observation device for pedestrian bridges is proposed. Summary of the Invention

[0004] In order to solve the above problems, the present application proposes a settlement observation device for a pedestrian bridge and a method of using the same.

[0005] A settlement observation device for a pedestrian bridge comprises a level and a placement platform. The bottom of the level is provided with a through hole, the surface of the placement platform is provided with an adjustment hole, a sliding rod is slidably connected in the adjustment hole, and an adjustment assembly is provided on the sliding rod.

[0006] The sliding rod moves vertically within the adjustment hole, directly changing the height of the level mounting base, reducing the number of steps required. This allows for quick raising and lowering of the entire level without the need for repeated tripod height adjustments.

[0007] Furthermore, the adjustment assembly includes a placement block fixedly connected to the top of the sliding rod. A fixed rod is fixedly connected to the placement block, and a bidirectional threaded rod is rotatably connected to the fixed rod. The two ends of the bidirectional threaded rod are respectively threadedly connected to the side clamping plates. The threads at the two ends of the bidirectional threaded rod are opposite, and the threads in the middle are the same as the threads at either end.

[0008] Rotate the two-way threaded rod to drive the two side clamps to move toward each other, clamping the bottom of the level to prevent the device from shaking.

[0009] Furthermore, a sliding rod is inserted into the through hole to allow the instrument to rotate around the sliding rod as the axis, so that the direction can be adjusted without disassembling and reassembling the instrument, allowing the level to rotate 360 ​​degrees freely and flexibly adjust the observation angle; rotating the two-way threaded rod drives the two side clamps to move toward each other, clamping the bottom of the level to prevent the level angle from deviating;

[0010] Furthermore, the adjustment assembly also includes a sliding plate threadedly connected to the bidirectional threaded rod, and a positioning plate is fixedly connected to the sliding plate; the sliding plate moves on the bidirectional threaded rod, pushing the positioning plate against the inner wall of the placement table, and at the same time, the lower surface of the other positioning plate abuts against the upper surface of the placement table to lock the height of the sliding rod.

[0011] Furthermore, a limit rod is fixedly connected to one side of the sliding rod, and a limit groove is provided on one side of the adjustment hole. The limit rod slides in the limit groove, constraining the sliding rod to move only vertically, preventing accidental deflection of the level and ensuring lifting stability.

[0012] Furthermore, a threaded column is fixedly connected to the bottom of the placement table, a support rod is hinged to the bottom of the placement table, and a support adjustment component is also included, and the threaded column and the support rod are connected through the support adjustment component.

[0013] Furthermore, the support adjustment assembly includes a threaded sleeve threadedly connected to the threaded column, the middle part of the threaded sleeve is rotatably connected to a rotating ring, the rotating ring is rotatably connected to a connecting rod, and the bottom of the support rod is fixedly connected to a support block; rotating the threaded sleeve drives the rotating ring to move downward, and the connecting rod pushes the three groups of support rods to unfold synchronously, so that the staff can operate with one hand and unfold the three support legs synchronously, thereby improving deployment efficiency.

[0014] Furthermore, the support block is shaped like a truncated cone, with the threaded column located directly below the adjustment hole. The bottom surface of the cone increases the contact area and disperses pressure, and is provided with an anti-slip texture, which can adapt to various surfaces, enhance grip, and reduce vibration interference.

[0015] Furthermore, three groups of support rods are provided and evenly distributed at the bottom of the placement table. The sliding rod is located inside the threaded column, and the end of the connecting rod away from the rotating ring is hinged to the support rod; the symmetrical layout can offset the unbalanced load and prevent the level from shaking.

[0016] Furthermore, the top of the sliding rod passes through the through hole, the top of the placement block fits into the bottom of the through hole, and the side clamping plates are slidably connected in the fixed rod and are located on both sides of the placement block.

[0017] Furthermore, the sliding plate is slidably connected to the bidirectional threaded rod, the sliding plate is located inside the sliding rod, and the positioning plates are provided in a plurality of groups and penetrate and slide on one side of the sliding rod.

[0018] A method for using a settlement observation device for a pedestrian bridge is as follows: a worker first manually rotates a threaded sleeve on a threaded column to drive a rotating ring to move downward. At this time, the rotating ring rotates on the threaded sleeve and drives a connecting rod to rotate on the rotating ring and a support rod, thereby driving the support rod to rotate and open at the bottom of the placement platform until the bottoms of the three sets of support blocks are horizontal to the ground. The device can then be supported and placed at a settlement observation point on the pedestrian bridge.

[0019] Then insert the through hole at the bottom of the level into the sliding rod and fit it on the top of the placement block. Then, you can rotate the level on the sliding rod to adjust the observation angle of the level. Then push the sliding rod to slide in the adjustment hole to make the limit rod slide in the limit groove.

[0020] After adjustment, manually rotate the two-way threaded rod to drive the two sets of side clamps to slide toward the middle on the fixed rod at the same time until they fit on both sides of the bottom of the level. When the two-way threaded rod rotates, the positioning plate will be pushed through one side of the sliding rod through the sliding plate to fix the height of the sliding rod. Finally, fine-tune and precisely adjust through the level to observe the settlement of the pedestrian bridge.

[0021] Compared with the prior art, the present application has the following beneficial effects: by placing the level on the placement block, the level can be quickly installed, and the level can be directly rotated on the placement block, and the sliding rod can slide in the adjustment hole, thereby quickly adjusting the height and angle of the level, and rotating the two-way threaded rod can drive the two sets of side clamps to move in relative directions and at the same time drive the positioning plate to move through the sliding plate to adjust the height and angle of the level.

[0022] The distance between the positioning plates is consistent with the thickness of the placement table, which ensures the stability of the sliding rod during use. By rotating the threaded sleeve to push the support rod to rotate under the action of the connecting rod, the support rod can be opened to support the device through the support block. While it can be opened quickly, the stability of the support can be guaranteed. The support block is frustum-shaped and made of rubber, which can avoid damage to the bridge pavement when used on a pedestrian bridge. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] The sliding plate 306 is driven by the bidirectional threaded rod 304 to move axially, and pushes the positioning plate 307 through the inclined surface to make it extend radially and press against the inner wall of the placement table 2 to fix the height.

[0044] One side of the sliding rod 301 is fixedly connected to a limiting rod 308 , and one side of the adjusting hole 201 is provided with a limiting groove 309 .
