Description

Technical Field

[0001] The invention relates to an improvement of a suspension bridge cable clamp inner hole measurement technology, belongs to the cable clamp inner hole measurement field, and in particular relates to a suspension bridge cable clamp inner hole measurement device. Background Art

[0002] In a suspension bridge structure, a cable clamp is a connector between the main cable and the bridge deck suspender cable. It is used to transfer the load of the bridge deck to the main cable and clamp the main cable. It is one of the important load-bearing structures in the suspension bridge structure. The cable clamp is generally divided into two halves, which are bolted together to clamp the main cable and ensure that the cable clamp does not slip with the main cable under the tensile load of the steel beam and the bridge deck. Therefore, the processing accuracy of the cable clamp inner hole diameter is an important indicator to measure the cable clamp processing quality. At present, there are two main methods for measuring the inner hole diameter of the cable clamp: one is to measure with a vernier caliper, and the other is to measure with an inside micrometer. The accuracy of the results of these two measurement methods mainly depends on the operator's experience, feel and reading angle. Due to the different feel and experience of the measurement personnel and the different angles when reading (when measuring with a vernier caliper, its inner measuring claw relies on manual labor to make it close to the inner wall of the cable clamp to be measured; when measuring with an inside micrometer, the tightness of the measuring knob and the fine-adjustment knob depends on manual feel and experience to judge; different measurements by the same measurement personnel and the angles of view when different measurement personnel take measurements will be different), resulting in deviations in the measurement data and readings, causing deviations and inaccuracies in the measurement results.

[0003] A Chinese patent application with application number CN202410086051.4, filed on January 22, 2024, discloses a method for spatial positioning and measurement of cable clamps for suspension bridges. The method comprises the following steps: Step 1: Calculating layout data for cable clamp construction and conducting on-site data measurements; Step 2: Installing the cable clamp based on the layout data and measured data in Step 1. Using a vernier universal angle ruler and a spirit level, the lateral inclination of the cable clamp is measured to determine and adjust the angle of the lug plate for final installation. After the main cable is laterally displaced and before the sling is installed, the lateral inclination of the cable clamp is measured using a vernier universal angle ruler and a spirit level according to monitoring instructions, and the angle of the lug plate is finally adjusted for final installation. This solution offers safe and reliable construction, high installation efficiency, and significantly shortens the construction period for cable clamp installation at the bridge site. However, it does not address the issue of inaccurate measurements of the cable clamp's inner hole.

The value is directly displayed on the scale on the measuring device, allowing for intuitive, efficient, and accurate measurement of the cable clamp's inner hole diameter. The first and second probes abut the left and right sides of the cable clamp's inner wall, respectively, measuring the cable clamp's inner hole from two directions.

Therefore, the cable clamp's inner hole measurement results are accurate.

Therefore, the present invention is easy to adjust and simple to operate.

[0018] 3. In a suspension bridge cable clamp inner bore measurement device according to the present invention, a measuring rod comprises a first measuring shaft and at least one second measuring shaft.

The length of the measuring rod 3 includes specifications such as 1000mm, 500mm, 200mm, 100mm, 50mm, 20mm, and 10mm. During actual measurement, the selection and combination are based on the basic size of the inner hole diameter of the rope clamp 1 to be measured.

[0045] Example 1: A device for measuring the inner hole of a cable clamp of a suspension bridge, comprising a clamping assembly 2, a measuring rod 3, a first probe 5, a second probe 51, a connecting seat 6, a sliding column 9 and a measuring column 10; the second probe 51 and the first probe 5 are respectively abutted against the left and right sides of the inner wall of the cable clamp 1, the end of the first probe 5 away from the inner wall of the cable clamp 1 is connected to one end of the measuring rod 3, the other end of the measuring rod 3 is connected to one end of the connecting seat 6, a spring 7 is provided in the inner cavity 63 of the connecting seat 6, and one end of the spring 7 is connected to the measuring column 10. The other end of the rod 3 is connected, the other end of the spring 7 is connected to the side of the sliding column 9, the sliding column 9 is movably cooperated with the inner cavity 63, and the end of the second measuring head 51 away from the inner wall of the cable clamp 1 is embedded in the sliding column 9; the top of the connecting seat 6 is plugged with a measuring column 10 with one end passing through the sliding column 9, and the side of the measuring column 10 contacts the end of the second measuring head 51 away from the inner wall of the cable clamp 1, and a scale 8 is installed on the measuring column 10, and the scale 8 is set on the top of the connecting seat 6; the clamping assembly 2 is sleeved on the outer side of the measuring rod 3.

[0046] During use: first hold the clamping assembly 2 and place the first measuring probe 5 against one side of the inner wall of the cable clamp 1. Then, under the compression force of the spring 7, the sliding column 9 slides along the connecting seat 6 to place the second measuring probe 51 against the other inner wall of the cable clamp 1. Then the spring 7 rebounds to fix the entire measuring assembly in the cable clamp 1. Then, the inner hole diameter of the cable clamp 1 measured by the second measuring probe 51 is fed back to the scale 8 through the measuring column 10, thereby obtaining the inner hole diameter of the cable clamp 1.

[0047] Example 2: Example 2 is basically the same as Example 1, except that: The clamping assembly 2 includes a clamping seat 21, a connecting rod 23 and a handle 24. The slot 211 of the clamping seat 21 is engaged with the outer side of the measuring rod 3, the top of the clamping seat 21 is connected to the bottom of the connecting rod 23, and the top of the connecting rod 23 is provided with a handle 24; the bottom of the clamping seat 21 is provided with a first buffer groove 212 connected to the top of the slot 211, and the bottom of the clamping seat 21 is provided with a second buffer groove 213 connected to the bottom of the slot 211, and the second buffer groove 213 is open; the side of the clamping seat 21 is threadedly fitted with a bolt 22 through the second buffer groove 213; the interior of the connecting rod 23 is provided with a longitudinally movable adjustment rod 231, and the upper end of the adjustment rod 231 is connected to the handle 24.

[0048] During use, the measuring rod 3 is placed in the slot 211 of the clamping seat 21, so that the outer side of the measuring rod 3 is engaged with the slot 211. At this time, the measuring rod 3 is initially fixed by the clamping seat 21. By tightening the bolt 22, the bolt 22 moves in the second buffer groove 213 toward the slot 211, thereby squeezing the measuring rod 3, so that the measuring rod 3 is further clamped and firmly fixed. The open setting of the second buffer groove 213 facilitates the screwing in and out operation of the bolt 22, and also provides a certain space for the movement of the bolt 22, so that it can better apply the clamping force to the measuring rod 3. When the measuring rod 3 needs to be fixed, first place the measuring rod 3 into the slot 211 of the clamping seat 21, and then tighten the bolt 22 so that the measuring rod 3 is firmly clamped in the clamping seat 21. At this time, the position of the measuring rod 3 is fixed and will not shake or move, providing stable conditions for subsequent measurements or other operations. If the position of the clamping assembly needs to be adjusted, the operator holds the handle 24 and moves the handle 24 up or down. The handle 24 drives the adjusting rod 231 to move up and down in the connecting rod 23, thereby changing the overall height position of the clamping assembly.

[0049] Example 3: Example 3 is basically the same as Example 1, except that: The measuring rod 3 includes a first measuring shaft 31 and at least one second measuring shaft 32. A first measuring head 5 is inserted into the right side of the first measuring shaft 31, and the first measuring head 5 and the first measuring shaft 31 are fixed by a locking nut 4. The left side of the first measuring shaft 31 is inserted into the right side of the second measuring shaft 32; the adjacent second measuring shafts 32 are inserted, and the left side of the leftmost second measuring shaft 32 is inserted into the right side of the connecting seat 6; a first thread groove 312 is provided on the right side of the first measuring shaft 31, and the first thread groove 312 is threadedly matched with the first measuring head 5; a clamping block 311 is provided on the left side of the first measuring shaft 31, and a fixing groove 322 adapted to the clamping block 311 is provided on the right side of the second measuring shaft 32, and the clamping block 311 is engaged with the fixing groove 322; a fixing block 321 adapted to the fixing groove 322 is provided on the left side of the second measuring shaft 32, and the adjacent second measuring shafts 32 are fixed by clamping the fixing block 321 with the fixing groove 322, and the fixing block 321 is inserted into the right side of the connecting seat 6.

[0050] During use: align the threaded portion of the first measuring head 5 with the first thread groove 312 on the right side of the first measuring shaft 31, then screw in the first measuring head 5 so that it is threadedly engaged with the first measuring shaft 31, and further secure the connection between the first measuring head 5 and the first measuring shaft 31 by tightening the locking nut 4 to ensure that the first measuring head 5 does not loosen during the measurement process, and then align the clamping block 311 on the left side of the first measuring shaft 31 with the fixing groove 322 on the right side of the second measuring shaft 32, and then insert the first measuring shaft 31 into the second measuring shaft 32 so that the clamping block 311 is engaged with the fixing groove 322, thereby achieving the connection between the first measuring shaft 31 and the second measuring shaft 32. This clamping connection method can ensure that the connection between the two measuring shafts is firm and stable; During use, the first measuring axis 31 can be used alone or together with an appropriate number of second measuring axes 32 according to the size of the actual measured object and the measurement range requirements, so as to adjust the overall length of the measuring rod 3. The retractable design enables the measuring rod 3 to adapt to measurement requirements of different lengths, thereby improving the versatility and flexibility of the measuring rod 3.

[0051] Example 4: Example 4 is basically the same as Example 1, except that: The connecting seat 6 includes a base 61 and a side seat 62.

A positioning piece 101 is provided in the oblong groove 64, and the bottom of the positioning piece 101 is clamped with the top of the sliding column 9.

[0052] During application: one end of the measuring column 10 is passed through the through groove 65 at the top of the base 61, and then plugged into the sliding column 9. This plug-in method allows the measuring column 10 to move axially in the through groove 65 while maintaining a stable connection with the sliding column 9. After the measuring column 10 is installed, the positioning piece 101 is installed in the oblong groove 64 so that the bottom of the positioning piece 101 is engaged with the top of the sliding column 9. The function of the positioning piece 101 is to limit the position of the sliding column 9 in the oblong groove 64 to prevent the sliding column 9 from unnecessary movement or shaking during the measurement process.
