Description

Technical Field

[0001] This utility model relates to the field of bridge construction technology, and in particular to a steel anchor beam levelness detection device. Background Technology

[0002] Steel anchor beams are crucial load-bearing components of cable-stayed bridges, and their installation is a key step in ensuring the safety and stability of the bridge structure. In traditional cable-stayed bridge anchor beam positioning, construction workers need to repeatedly measure to ensure the anchor beams are level.

[0003] Traditional measurement methods include external control measurement and internal control measurement. External control measurement involves setting control points on the ground and using a total station to measure the coordinates of these points on the steel anchor beam. Internal control measurement involves first transmitting the control points to the tower column, and then setting up a station at the tower column control point to measure the coordinates. These methods are complex and reduce construction difficulty. Furthermore, traditional measurement methods are easily affected by lighting, moisture, and platform sway, making it difficult to meet the accuracy requirements for steel anchor beam construction.

[0035] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0036] The steel anchor beam levelness detection device provided by this utility model can simplify the measurement process of steel anchor beam levelness, improve construction efficiency, and reduce the influence of light, water vapor and measurement platform shaking, thus meeting the construction accuracy requirements of steel anchor beams.

[0037] See Figures 1 to 5The steel anchor beam levelness detection device includes a connecting member 1, a connecting pipe 2, and at least three sets of fixing components 4. At least three connecting pipes 2 are interconnected through the connecting member 1. A transparent detection pipe 3 is fixedly connected to the end of each connecting pipe 2 away from the connecting member 1. The detection pipe 3 is connected to the connecting pipe 2 and can extend in the vertical direction. The outer surface of the detection pipe 3 is provided with scale lines 31. Each set of fixing components 4 includes a locking ring 41 and a clamping member 42. The locking ring 41 and the clamping member 42 are fixedly connected. Each detection pipe 3 can be fixedly connected to a locking ring 41. One set of fixing components 4 can fix one detection pipe 3 to one side of the steel anchor beam 100, and the other sets of fixing components 4 can fix the remaining detection pipe 3 to the other side of the steel anchor beam 100.

[0038] The steel anchor beam levelness detection device provided by this utility model includes a connecting member 1, a connecting pipe 2, and a fixing component 4. In use, the locking ring 41 locks the detection pipe, and the clamping member 42 clamps the steel anchor beam 100. This ensures that the connecting pipes 2 are distributed on both sides of the steel anchor beam 100, and the scale line 31 is flush with the top surface of the steel anchor beam 100. Water is injected into the connecting pipes 2, and the transparent detection pipe 3 facilitates observation of the water interface within the detection pipe 3. Observing the water interfaces in the detection pipes 3 on both sides of the steel anchor beam 100, if the water interface is flush with the scale line 31, it indicates that the steel anchor beam 100 is level along its width direction; if not, the steel anchor beam 100 is rotated until the water interface in the detection pipes 3 on both sides of the steel anchor beam 100 is flush with the scale line 31. Next, observe the water interface in the detection tube 3 on the same side of the steel anchor beam 100. If the water interface is flush with the scale line 31, it indicates that the steel anchor beam 100 is horizontal along its length. If it is not flush, rotate the steel anchor beam 100 until the water interface in the detection tubes 3 on both sides of the steel anchor beam 100 is flush with the scale line 31. The steel anchor beam levelness detection device provided by this utility model has a simple measurement process, improves construction efficiency, and can reduce the influence of light, water vapor, and measurement platform shaking, thus meeting the construction accuracy requirements of the steel anchor beam 100.

[0039] The number of channels in connector 1 needs to be selected based on the number of connecting pipes 2. If there are three connecting pipes 2, connector 1 only needs three channels; if there are four connecting pipes 2, connector 1 needs four channels.

[0040] Optionally, three connecting pipes 2 are provided, and three sets of fixing components 4 are provided. One set of fixing components 4 can fix one of the connecting pipes 2 to one side of the steel anchor beam 100, and the other sets of fixing components 4 can fix the remaining connecting pipes 2 to the other side of the steel anchor beam 100. The three connecting pipes 2 form a plane. By observing whether the water interface and the scale line 31 are aligned, it can be determined whether the steel anchor beam 100 is horizontal, and then the steel anchor beam 100 can be adjusted to a horizontal state.

[0041] Preferably, the steel anchor beam levelness detection device includes four connecting pipes 2 and four sets of fixing components 4. Two sets of fixing components 4 fix two of the connecting pipes 2 to one side of the steel anchor beam 100, and the other two sets of fixing components 4 fix the other two connecting pipes 2 to one side of the steel anchor beam 100. The connecting pipes 2 on the same side of the steel anchor beam 100 are spaced apart. By observing the alignment of the water interface and scale line 31 in the two connecting pipes 2 from any side of the steel anchor beam 100, the levelness of the steel anchor beam 100 along its length can be corrected, thus improving construction efficiency.

[0042] Optionally, the connecting part 1 is a four-way pipe fitting made of polyvinyl chloride, which is inexpensive and can reduce construction costs.

[0043] For example, the connecting tube 2 is a flexible tube, and the detection tube 3 is a rigid tube. The flexible tube is deformable, which improves the connection flexibility, while the rigid tube can improve the stability of the measurement and reduce measurement errors. Optionally, the connecting tube 2 can be a rubber tube, and the rigid tube can be a transparent plastic tube.

[0044] Specifically, the connecting pipe 2 is fitted onto the connecting member 1, and a first sealing element is sandwiched between the connecting member 1 and the connecting pipe 2. The connecting pipe 2 is a flexible hose, and its fitting onto the connecting member 1 is convenient, reducing construction difficulty. The first sealing element improves the sealing performance of the steel anchor beam level detection device, and improves the measurement accuracy by utilizing the principle of communicating vessels to measure the levelness of the steel anchor beam 100. The first sealing element can be an existing rubber ring, which is readily available and easy to install.

[0045] Specifically, the connecting pipe 2 is fitted onto the detection pipe 3, and a second sealing element is installed between the connecting pipe 2 and the detection pipe 3. The connecting pipe 2 is a flexible tube, which facilitates its connection to the detection pipe 3 and reduces construction difficulty. The second sealing element improves the sealing performance of the steel anchor beam leveling detection device, and improves the measurement accuracy by utilizing the principle of communicating vessels to measure the levelness of the steel anchor beam 100. The second sealing element can be an existing rubber ring, which is readily available and easy to install.

[0046] The fixing component 4 includes a locking ring 41 and a clamping member 42. The locking ring 41 can lock the detection tube 3, so that the fixing component 4 can drive the detection tube 3 to move. The detection tube 3 drives the connecting tube 2 to move, which makes it easier for the clamping member 42 to clamp onto the steel anchor beam 100 and improves the connection flexibility.

[0047] Clamping member 42 is used to fix the connecting pipe 2 and the steel anchor beam 100. In this embodiment, see Figure 1 and Figure 3The clamping member 42 includes a clamping part 421 and a pushing part 422. The clamping part 421 is fixedly connected to the locking ring 41 and can clamp the steel anchor beam 100. The pushing part 422 is connected to the clamping part 421 and can press the steel anchor beam 100 to fix the clamping member 42 and the steel anchor beam 100. The pushing part 422 presses the steel anchor beam 100 to fix the steel anchor beam 100 and the clamping member 42, so that the clamping member 42 is applicable to steel anchor beams 100 of different thicknesses, thus improving the applicability of the clamping member 42.

[0048] Specifically, the clamping part 421 has a receiving groove 4211 for receiving the steel anchor beam 100. The groove wall of the receiving groove 4211 has a threaded hole, and the pushing part 422 is a push screw that is screwed into the threaded hole. The receiving groove 4211 can coarsely position the steel anchor beam 100 by receiving it, and the threaded connection has a self-locking effect, which improves the clamping effect.

[0049] Each of the two side walls of the receiving groove 4211 can be provided with a set screw. The two set screws are close to each other to clamp the steel anchor beam 100. The set screws are threaded to the clamping part 421, thereby fixing the clamping part 42 to the steel anchor beam 100.

[0050] Preferably, see Figure 1 and Figure 3 A set screw is provided on one side wall of the receiving groove 4211. The set screw is rotated and pressed so that the set screw and the other side wall of the receiving groove 4211 clamp the steel anchor beam 100. This eliminates the need for two set screws, reducing processing difficulty and lowering processing costs.

[0051] In use, the locking ring 41 is fitted onto the outer wall of the detection tube 3, and the locking ring 41 is tightened to fix the locking ring 41 and the detection tube 3. The clamping member 42 is moved so that the steel anchor beam 100 is placed in the receiving groove 4211, and the set screw is rotated so that the set screw presses the steel anchor beam 100 into the receiving groove 4211. The locking ring 41 can be an existing clamp.

[0052] Optionally, the clamping part 421 has a receiving groove 4211, and elastic elements are provided on the inner walls of both sides of the receiving groove 4211. The elastic elements can clamp the steel anchor beam 100. In use, the locking ring 41 is sleeved on the outer wall of the detection tube 3, compressing the elastic elements on both sides of the receiving groove 4211. The clamping member 42 is moved so that the steel anchor beam 100 is placed in the receiving groove 4211. The elastic elements are then released, and the elastic elements clamp the steel anchor beam 100. The buffering effect of the elastic elements can absorb external vibration or impact loads, reduce the relative displacement between the steel anchor beam 100 and the clamping part 421, ensure the positional relationship between the detection tube 3 and the steel anchor beam 100, and improve the accuracy of levelness detection.

[0053] Existing springs can be used as the elastic element.

[0054] To improve the efficiency of leveling the steel anchor beam 100, in this embodiment, see... Figures 1 to 3 The detection tube 3 is equipped with multiple scale lines 31, each marked with a scale value, which increases sequentially from bottom to top. By observing the difference in scale values ​​between the lower interface of the steel anchor beam 100 and the water interface inside the detection tube 3, the rotation range of the steel anchor beam 100 can be adjusted based on this difference, thus improving adjustment efficiency.

[0055] The scale values ​​of the scale line 31 increase sequentially from bottom to top, which facilitates quick positioning by construction personnel, reduces the time spent scanning back and forth, and allows for rapid acquisition of the difference between the scale values ​​of the water interface of the detection pipe 3 and the steel anchor beam 100, thereby adjusting the steel anchor beam 100 and improving construction efficiency.

[0056] Furthermore, the accuracy of the scale line 31 is not less than 0.5mm, ensuring that the levelness of the steel anchor beam 100 meets the construction accuracy requirements of the steel anchor beam 100.

[0057] The steel anchor beam levelness detection device provided by this utility model involves connecting four connecting pipes 2 to a connecting member 1 during use, ensuring that the four connecting pipes 2 are in a connected state. Correspondingly, a detection pipe 3 is inserted into the end of each connecting pipe 2 away from the connecting member 1, ensuring that the four detection pipes 3 are in a connected state and that there is a good seal between the detection pipes 3, the connecting pipes 2, and the connecting member 1. Then, a set of fixing components 4 is fixed to each detection pipe 3, with a locking ring 41 locking onto the detection pipe 3. A clamping member 42 moves the detection pipe 3 and the connecting pipe 2 to clamp them onto the steel anchor beam 100, ensuring that there are two spaced detection pipes 3 on each opposite side of the steel anchor beam 100, and that the scale line 31 of the detection pipe 3 is aligned with the upper surface of the steel anchor beam 100. Then, water is injected into one of the detection pipes 3; according to the principle of communicating vessels, the water interface in each detection pipe 3 is flush. Observe the difference between the scale value of the water interface and the scale line 31 corresponding to the upper surface of the steel anchor beam 100, and adjust the steel anchor beam 100 accordingly so that the scale value of the interface and the scale line 31 corresponding to the upper surface of the steel anchor beam 100 are equal. This indicates that the steel anchor beam 100 is in a horizontal state, and the precise horizontal adjustment of the steel anchor positioning is completed.

[0058] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here.
