Abstract
Description
Technical Field
[0001] This utility model relates to the field of bridge inspection technology, and specifically discloses a device for measuring the inclination angle of large-diameter long piles. Background Technology
[0002] When constructing a bridge, the first step is to pour a long pile foundation. Measuring the inclination angle of the long pile is crucial. As the foundation, the long pile needs to withstand vertical forces. When the long pile is significantly tilted, it will be difficult to withstand the various loads required by the design. Therefore, it is necessary to measure and correct the long pile to ensure its safety during use.
[0003] Existing long pile testing devices typically use straightedges or angle measuring instruments to directly measure the inclination angle during testing. The measuring tools are limited, and because long piles are circular, workers need to take repeated measurements to find the correct reference. This makes it difficult to accurately know whether there is a deviation in the benchmark during measurement, which leads to a decrease in the accuracy of long pile measurements. Utility Model Content
[0004] In view of this, the purpose of this utility model is to provide a large-diameter long pile inclination angle measuring device to solve the technical problem that existing long pile detection devices usually use a straightedge or angle measuring instrument to directly measure the inclination angle, resulting in low measurement accuracy.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a device for measuring the inclination angle of a large-diameter long pile, comprising a connecting frame, a rectangular block fixedly connected to the connecting frame, an angle adjuster mounted on the rectangular block, a fixed end of the angle adjuster fixedly connected to the rectangular block, a movable plate mounted on the output end of the angle adjuster, and a level mounted on the movable plate; both ends of the connecting frame are provided with clamping mechanisms for fixing the device to the long pile. In use, the operator uses the angle adjuster in conjunction with the level to measure the inclination angle of the long pile, ensuring the accuracy of the measurement results.
[0006] Furthermore, the clamping mechanism includes two sets of first arc-shaped frames, one set of which is fixedly connected to the connecting frame, with the centers of both sets of first arc-shaped frames facing the long pile. One set of first arc-shaped frames has first mating blocks at both ends, and the other set has second mating blocks at both ends. The first mating blocks are respectively inserted into the second mating blocks. The clamping mechanism is fitted onto and clamped onto the long pile using the two sets of first arc-shaped frames. The two sets of clamping mechanisms are located at two points on the long pile, ensuring that the connecting block between the two sets of clamping mechanisms remains parallel to the long pile. This facilitates subsequent measurement of the pile's inclination angle while ensuring measurement accuracy.
[0007] Furthermore, each of the two sets of second mating blocks has a fixing sleeve fitted at one end. The fixing sleeve is fixedly connected to the second mating block by fastening bolts, and a fixing block is provided between the two sets of fixing sleeves. A rotatable threaded post is provided on the fixing block. A handwheel is fixedly connected to one end of the threaded post, and a rotatable movable block is provided at the other end. The movable block is engaged with one of the first arc-shaped frames. By cooperating with the fixing block, the threaded post, and the movable block, the distance between the two sets of first arc-shaped blocks can be adjusted, thereby achieving the purpose of fixing the two sets of first arc-shaped blocks on the long pile. At the same time, the threaded post and the movable block are rotatably connected, and the threaded post can also push the first arc-shaped frame to move while pushing the movable block.
[0008] Furthermore, the first arc-shaped frame is equipped with several sets of auxiliary positioning components, which are respectively located on both sides of the first arc-shaped frame. Each auxiliary positioning component includes a fixed column with a rotatable fitting sleeve. Second arc-shaped frames are fixedly connected to both sides of the fitting sleeve. Each of the two sets of second arc-shaped frames has a rotatable movable column at one end, which contacts the long pile. The auxiliary positioning components enable line contact between the clamping mechanism and the long pile, thereby reducing the impact of unevenness on the surface of the long pile on the clamping mechanism, ensuring that the connecting frame and the long pile remain parallel, and improving the accuracy of the operator's measurement of the long pile angle.
[0009] Furthermore, both the first and second mating blocks have rectangular cross-sections, and there is no relative rotation between the second and first mating blocks. The first and second mating blocks cooperate with each other, ensuring that the two sets of first arc-shaped frames are always located in the same horizontal plane without relative rotation, thereby guaranteeing that the connecting frame remains horizontal with the long pile.
[0010] Furthermore, several sets of auxiliary positioning components located on the same horizontal plane are situated at the four corners of the rectangle, with both sets of second arc-shaped frames facing the long pile. The contact between the auxiliary positioning components and the long pile is line contact, thereby ensuring the accuracy of the worker's inspection.
[0011] The working principle and beneficial effects of this solution are as follows:
[0012] In use, the connecting frame is fixed to the long pile by two sets of clamping mechanisms. At the same time, several sets of auxiliary positioning components are oriented towards the long pile. The connecting frame is fixed by the line contact between the auxiliary positioning components and the long pile. The line contact between the auxiliary positioning components and the long pile can reduce the impact of unevenness on the surface of the long pile on the clamping mechanism. At the same time, the several sets of auxiliary positioning components can increase the friction between the clamping mechanism and the long pile, ensuring that the clamping mechanism can be firmly fixed to the long pile and always keep the fixing frame parallel to the long pile to ensure measurement accuracy.
[0013] Workers adjust the angle of the movable plate using an angle adjuster. When the level on the movable plate shows horizontal, they stop adjusting the angle adjuster and observe the angle displayed on it. By observing the angle, workers can determine the inclination angle of the long pile. Workers can quickly determine the inclination angle of the long pile, and the measurement results are accurate, eliminating the need for multiple measurements and thus improving measurement efficiency.

[0021] The following detailed description illustrates the specific implementation method:
[0022] Example
[0023] like Figures 1 to 5As shown, a large-diameter long pile inclination angle measuring device is disclosed, including a connecting frame 15, a rectangular block 16 fixedly connected to the connecting frame 15, an angle adjuster 17 provided on the rectangular block 16, the fixed end of the angle adjuster 17 being fixedly connected to the rectangular block 16 by bolts, a movable plate 18 provided at the output end of the angle adjuster 17, and a level 19 provided on the movable plate 18; wherein the angle adjuster 17 and the level 19 are both technical means commonly used by those skilled in the art, and their structure, usage and connection methods are well known to those skilled in the art. The angle adjuster 17 can adjust the angle of the movable plate 18 and record the adjusted angle.
[0024] Clamping mechanisms are provided on both sides of the connecting frame 15. Each clamping mechanism includes two sets of first arc-shaped frames 2, the radius of which is larger than the radius of the long pile 1. One set of first arc-shaped frames 2 has first mating blocks 3 fixedly connected to both ends, and the other set of first arc-shaped frames 2 has second mating blocks 4 fixedly connected to both ends. The two sets of second mating blocks 4 are respectively fitted onto the two sets of first mating blocks 3. Both the first mating blocks 3 and the second mating blocks 4 have rectangular cross-sections. The contact area between the second mating blocks 4 and the first mating blocks 3 is large, ensuring that the second mating blocks 4 do not wrap around the first mating blocks. 3. Rotate, the two sets of first arc-shaped frames 2 are located on both sides of the long pile 1 and are in contact with the long pile 1. The first arc-shaped frame 2 and the long pile 1 are in line contact. The other end of the two sets of first mating blocks 3 is fitted with a fixing sleeve 6. The fixing sleeve 6 is fixedly connected to the fixing block 5 by fastening bolts 7. A fixing block 5 is set between the two sets of fixing sleeves 6. The two ends of the fixing block 5 are fixedly connected to the two sets of fixing sleeves 6 respectively. A threaded column 8 is installed inside the fixing block 5. A handwheel 9 is set at one end of the threaded column 8, and a rotatable movable block 10 is set at the other end. The movable block 10 is snapped onto the first arc-shaped frame 2. Figures 2 to 4 As shown.
[0025] The first arc-shaped frame 2 is equipped with several sets of auxiliary positioning components, which are located on both sides of the first arc-shaped frame 2. Each auxiliary positioning component includes a fixed column 11, which is fixedly connected to the first arc-shaped frame 2. A mating sleeve 12 is fitted onto the fixed column 11, and the mating sleeve 12 is rotatably connected to the fixed column 11. Second arc-shaped frames 13 are fixedly connected to both sides of the mating sleeve 12. Each of the two sets of second arc-shaped frames 13 is equipped with a rotatable movable column 14, and both sets of movable columns 14 are in contact with the long pile 1. Figure 5 As shown.
[0026] In use, the operator first moves the connecting frame 15 and the corresponding two sets of first arc-shaped frames 2 onto the long pile 1, while adjusting the position of the auxiliary positioning components so that the two sets of movable columns 14 contact the long pile 1. At this time, the movable columns 14 and the long pile 1 are in line contact. Then, the operator moves the other set of first arc-shaped frames 2 so that the two sets of second mating blocks 4 are aligned with the two sets of first mating blocks 3 respectively. Then, the operator moves the first arc-shaped frame 2 horizontally, driving the two sets of second mating blocks 4 to move. At this time, the two sets of second mating blocks 4 slide within the two sets of first mating blocks 3 respectively. Because the contact surface between the first mating block 3 and the second mating block 4 is relatively large, the two sets of first arc-shaped frames 2 located on the same horizontal plane always remain parallel, and the two sets of first arc-shaped frames 2 will not tilt, thus ensuring the accuracy of subsequent measurements. Then, the operator moves the fixing block 5 so that the two sets of fixing sleeves 6 are respectively fitted onto the corresponding two sets of first mating blocks 3. Then, the fixing sleeves 6 are fixedly connected to the corresponding first mating blocks 3 by fastening bolts 7. At this time, the fixing block 5 is fixedly connected to the first mating block 3. On the first mating block 3, the worker rotates the handwheel 9, which drives the threaded column 8 to rotate. While rotating within the fixed block 5, the threaded column 8 moves towards the first arc frame 2. Simultaneously, the threaded column 8 drives the movable block 10 to move until the movable block 10 moves to the vicinity of the first arc frame 2. Then, the worker adjusts the angle of the movable block 10 so that it is horizontal with the first arc frame 2. The worker continues to rotate the handwheel 9. At this time, the threaded column 8 rotates within the movable block 10, driving the movable block 10 to move, so that the movable block 10 is locked onto the first arc frame 2. Then, the threaded column 8 pushes the first arc frame 2 and the second mating block 4 to move. The second mating block 4 moves within the first mating block 3. When the first arc frame 2 approaches the long pile 1, the worker adjusts the mating sleeve 12 and the second arc frame 13 so that the movable column 14 faces the long pile 1. Then, the worker continues to rotate the handwheel 9 until the movable column 14 on the first arc frame 2 contacts the long pile 1. At this time, the two sets of first arc frames 2 located on the same horizontal plane clamp the long pile 1.
[0027] At this time, the connecting frame 15 is parallel to the long pile 1. Then, the staff activates the angle adjuster 17 and adjusts the angle of the movable plate 18 until the level 19 on the movable plate 18 shows horizontal. At this time, the level 19 is kept still. The staff can determine the inclination angle of the long pile 1 by observing the angle displayed by the angle adjuster 17. Since the connecting frame 15 is parallel to the long pile 1 at this time, the level 19 is in a horizontal state when the movable plate 18 is perpendicular to the connecting frame 15, so the accuracy of the inclination angle measurement of the long pile 1 can be guaranteed.
[0028] When the staff completes the measurement, the measuring device needs to be disassembled. At this time, the staff only needs to remove the fastening bolt 7, which releases the fixation between the fixing sleeve 6 and the first mating block 3. Then, the staff moves the fixing block 5 horizontally to separate the fixing sleeve 6 from the first mating block 3. At this time, the fixation between the two sets of first arc-shaped frames 2 is released. Then, the staff removes one set of first arc-shaped frames 2, which causes the second mating block 4 to slide inside the first mating block 3 until the first mating block 3 and the second mating block 4 are separated. At this time, the connecting frame 15 can be separated from the corresponding two sets of first arc-shaped frames 2 and the long pile 1, completing the disassembly of the measuring device. The disassembly process is simple and easy, thus improving the efficiency of disassembling the measuring device.
[0029] The above description is merely an embodiment of this utility model, and common knowledge such as specific structures and characteristics in the solution is not described in detail here. It should be noted that those skilled in the art can make several modifications and improvements without departing from the structure of this utility model, and these should also be considered within the protection scope of this utility model. These modifications and improvements will not affect the effectiveness of the implementation of this utility model or its practicality.
