Technical Field
[0001] This utility model relates to the field of corrugated pipe technology for box girders, and specifically to a positioning and detection tooling. Background Technology
[0002] Corrugated pipes for box girders are components specifically used in prestressed concrete box girders to provide ducts for prestressed steel strands. Traditionally, during the installation and inspection of corrugated pipes, both the box girder reinforcement and the corrugated pipes are installed and positioned on a jig. After the foundation is completed, they are hoisted to the box girder platform formwork for detailed binding. Current methods for positioning corrugated pipes mostly involve setting positioning coordinates on the box girder jig. Construction workers then use a grid or U-shaped reinforcement welded to the positioning. Once the bottom web steel is installed and ready for inspection, quality inspectors typically use a measuring tape and welding rods, or short reinforcing bars, to verify the corrugated pipe position. However, deviations in the verticality of the measuring tape and the horizontality of the welding rods or reinforcement bars cannot completely eliminate the impact of these errors on the quality of prestressed construction, significantly reducing construction efficiency and potentially leading to structural safety issues. Utility Model Content
[0003] (i) The technical problem solved by this utility model is: the installation and inspection of corrugated pipes for box girders in the prior art cannot completely eliminate the impact of errors on the quality of prestressed construction, which will significantly reduce construction efficiency and may even lead to structural safety problems.
[0004] (II) Technical Solution To solve the above-mentioned technical problems, embodiments of this utility model provide a positioning and detection fixture, including a base, a vertical plate, a horizontal telescopic rod, a leveling mechanism, and a distance measuring mechanism; The base is placed on a fixed surface, the vertical plate is connected to the base, and the vertical plate is perpendicular to the base; The horizontal telescopic rod is connected to the vertical plate. The horizontal telescopic rod can slide along the extension direction of the vertical plate. The horizontal telescopic rod is perpendicular to the vertical plate. The horizontal telescopic rod can also extend and retract along its own extension direction to abut or release the corrugated pipe. Both the leveling mechanism and the distance measuring mechanism are installed on the horizontal telescopic rod. The leveling mechanism is used to keep the horizontal telescopic rod horizontal, and the distance measuring mechanism is used to measure the distance between the horizontal telescopic rod and the end of the box girder.
[0005] Furthermore, the end of the horizontal telescopic rod facing the telescopic bellows is provided with a retaining ring, which abuts against the bellows.
[0006] Furthermore, the horizontal telescopic rod includes a first rod body, a second rod body, and a third rod body connected in sequence; The first rod is slidably mounted on the vertical plate, and a first spring bolt is provided at the connection between the first rod and the second rod, and a second spring bolt is provided at the connection between the second rod and the third rod; The second rod can slide in the opposite direction of the extension of the first rod, and the third rod can slide in the extension direction of the second rod.
[0007] Furthermore, a connecting rod 7 is connected to the side of the retaining ring facing away from the bellows, and the connecting rod 7 is detachably installed on the end of the third rod body facing the bellows.

[0014] The beneficial effects of this utility model are as follows: This utility model provides a positioning and detection fixture, including a base, a vertical plate, a horizontal telescopic rod, a leveling mechanism, and a distance measuring mechanism. In use, the base is placed on a fixed surface. Since the vertical plate is perpendicular to the base and the horizontal telescopic rod is perpendicular to the vertical plate, the horizontal telescopic rod slides along the extension direction of the vertical plate to the corresponding position. Simultaneously, the leveling mechanism and the distance measuring mechanism are installed on the horizontal telescopic rod. The leveling mechanism keeps the horizontal telescopic rod horizontal, monitoring disturbances generated during construction. The distance measuring mechanism measures the distance between the horizontal telescopic rod and the end of the box girder. In other words, the vertical plate, horizontal plate, and distance measuring mechanism correspond to the actual three-dimensional coordinates required for the corrugated pipe. Finally, the horizontal telescopic rod extends and retracts along its own extension direction to hold the corrugated pipe in place, thereby accurately locating the coordinates of the corrugated pipe within the box girder. This fixture can be used in construction positioning and subsequent inspection processes, effectively eliminating errors and significantly improving construction efficiency and quality.

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the connection within two components.

Furthermore, in the description of this utility model, unless otherwise stated, "a plurality of" means two or more.
[0021] Example 1 like Figures 1 to 2 As shown, this utility model provides a positioning and detection fixture, including a base 100, a vertical plate 200, a horizontal telescopic rod 300, a leveling mechanism, and a distance measuring mechanism; The base 100 is placed on a fixed surface, and the vertical plate 200 is connected to the base 100, with the vertical plate 200 and the base 100 being perpendicular to each other; The horizontal telescopic rod 300 is connected to the vertical plate 200. The horizontal telescopic rod 300 can slide along the extension direction of the vertical plate 200. The horizontal telescopic rod 300 and the vertical plate 200 are perpendicular to each other. The horizontal telescopic rod 300 can also extend and retract along its own extension direction to abut or release the corrugated pipe 500. Both the leveling mechanism and the distance measuring mechanism are installed on the horizontal telescopic bar 300. The leveling mechanism is used to keep the horizontal telescopic bar 300 horizontal, and the distance measuring mechanism is used to measure the distance between the horizontal telescopic bar 300 and the end of the box girder.
[0022] In this embodiment, the positioning and detection fixture includes a base 100, a vertical plate 200, a horizontal telescopic rod 300, a leveling mechanism, and a distance measuring mechanism. In use, the base 100 is placed on a fixed surface. Since the vertical plate 200 is perpendicular to the base 100 and the horizontal telescopic rod 300 is perpendicular to the vertical plate 200, the horizontal telescopic rod 300 is slid along the extension direction of the vertical plate 200 to the corresponding position. Simultaneously, a leveling mechanism and a distance measuring mechanism are also installed on the horizontal telescopic rod 300. The leveling mechanism ensures that the horizontal telescopic rod 300 remains level. The system maintains a horizontal position and monitors disturbances during construction. A distance measuring mechanism can measure the distance between the horizontal telescopic rod 300 and the end of the box girder. In other words, the vertical plate 200, horizontal plate, and distance measuring mechanism correspond to the actual three-dimensional coordinates of the corrugated pipe 500. Finally, the horizontal telescopic rod 300 extends and retracts along its own extension direction to hold the corrugated pipe 500 in place, thus accurately positioning the corrugated pipe 500 within the box girder. This system can be used in construction positioning and subsequent inspection processes, effectively eliminating errors and significantly improving construction efficiency and quality.
[0023] According to one embodiment provided by this utility model, such as Figure 1 and Figure 2 As shown, the end of the horizontal telescopic rod 300 facing the telescopic corrugated pipe 500 is provided with a retaining ring 301, which abuts against the corrugated pipe 500.
[0024] In this embodiment, a retaining ring 301 is provided at the end of the horizontal telescopic rod 300 facing the telescopic corrugated pipe 500. During positioning or testing, the retaining ring 301 abuts against the corrugated pipe 500, and the retaining ring 301 can position the corrugated pipe 500 to spatially constrain it. At the same time, since there may be vibrations at the construction site, the use of the retaining ring 301 to constrain the corrugated pipe 500 can resist the interference caused by construction vibrations.
[0025] Preferably, the retaining ring 301 is in the shape of a semi-circular ring, that is, the retaining ring 301 is a semi-circular arc-shaped clamping piece, and the size of the retaining ring 301 is directly adapted to the corresponding corrugated pipe 500 model, so that the retaining ring 301 can be fully adapted to the corrugated pipe 500 and can adaptively wrap around the corrugated pipe 500.
[0026] According to one embodiment provided by this utility model, such as Figure 1 and Figure 2 As shown, the horizontal telescopic pole 300 includes a first pole body 302, a second pole body 303, and a third pole body 304 connected in sequence; The first rod 302 is slidably mounted on the vertical plate 200. A first spring bolt 305 is provided at the connection between the first rod 302 and the second rod 303, and a second spring bolt 306 is provided at the connection between the second rod 303 and the third rod 304. The second rod 303 can slide in the opposite direction of the extension of the first rod 302, and the third rod 304 can slide in the extension direction of the second rod 303.
[0027] In this embodiment, the first rod 302 has a connecting hole, and the first rod 302 is slidably sleeved on the outside of the vertical plate 200 through the connecting hole, so that the first rod 302 can slide along the extension direction of the vertical plate 200, thereby driving the second rod 303 and the third rod 304 to move synchronously. Since the second rod 303 can slide in the opposite direction of the extension of the first rod 302, and the third rod 304 can slide along the extension direction of the second rod 303, when the horizontal telescopic rod 300 slides along the vertical plate 200 to a specified height, the corresponding length of the second rod 303 and the third rod 304 can be pulled out according to the usage requirements. In order to facilitate intuitive reading of the length value, scale lines 201 are provided on the outer walls of the first rod 302, the second rod 303 and the third rod 304, and the first rod 302 and the second rod 304 are also provided with scale lines 201. A first spring bolt 305 is provided at the connection point 03, and a second spring bolt 306 is provided at the connection point between the second rod 303 and the third rod 304. Preferably, both the first spring bolt 305 and the second spring bolt 306 are push-type spring bolts. The push-ends of the first spring bolt 305 and the second spring bolt 306 protrude from the side wall of the horizontal telescopic rod 300. In use, by pressing the first spring bolt 305 and the second spring bolt 306 into the horizontal telescopic rod 300, the corresponding lengths of the second rod 303 and the third rod 304 can be pulled out or retracted. When the required value is reached, the push-ends are released, and the first rod 302, the second rod 303, and the third rod 304 can be relatively fixed by the first spring bolt 305 and the second spring bolt 306, so that the three can be rigidly locked and always remain horizontal, which facilitates the accuracy of positioning and detection.
[0028] Of course, in order to facilitate the sliding of the horizontal telescopic rod 300 along the extension direction of the vertical plate 200, a third spring bolt 308 is provided at the connection between the horizontal telescopic rod 300 and the vertical plate 200. When it is necessary to slide the horizontal telescopic rod 300 along the extension direction of the vertical plate 200, press and slide the third spring bolt 308. When it slides to the corresponding position, release the third spring bolt 308 so that the first rod body 302 can be fixed relative to the vertical plate 200.
[0029] According to one embodiment provided by this utility model, such as Figure 1 and Figure 2 As shown, the side of the retaining ring 301 facing away from the bellows 500 is connected to a connecting rod 307, which is detachably installed on the end of the third rod 304 facing the bellows 500.
[0030] In this embodiment, in order to ensure that the retaining ring 301 abuts and constrains the bellows 500 while keeping it at the same horizontal height as the horizontal telescopic rod 300, a connecting rod 307 is connected to the side of the retaining ring 301 away from the bellows 500. Correspondingly, an installation hole is provided at the end of the third rod 304 facing the bellows 500. The assembly of the connecting rod 307 and the third rod 304 can be completed by directly inserting the connecting rod 307 into the installation hole.
[0031] By equipping multiple connecting rods 307 with retaining rings 301 of different sizes at the ends of the multiple connecting rods 307, it can be adapted to different models of bellows 500. When using it, you can simply replace the corresponding connecting rod 307 and retaining ring 301, which is very convenient and has high applicability.
[0032] According to one embodiment provided by this utility model, such as Figure 1 and Figure 2 As shown, the leveling mechanism includes a leveling component, which is installed on the first rod 302.
[0033] In this embodiment, in order to ensure that the horizontal telescopic rod 300 is always in a horizontal position, that is, kept horizontal with the horizontal plane, a leveling component is installed on the first rod body 302. The operator can confirm whether the horizontal telescopic rod 300 is in a horizontal state by observing the leveling component, so as to ensure the accuracy of positioning and detection.
[0034] According to one embodiment provided by this utility model, such as Figure 1 and Figure 2 As shown, the leveling component is an electronic angle ruler 400.
[0035] In this embodiment, preferably, to facilitate the operator's intuitive judgment of whether the horizontal telescopic rod 300 is horizontal, an electronic angle gauge 400 is used as the leveling component. Of course, to make it easier for the electronic angle gauge 400 to be installed on the first rod 302, a magnetic electronic angle gauge 400 is selected. At the construction site, the horizontal telescopic rods 300 are all made of metal, so the magnetic electronic angle gauge 400 can be directly attached to the first rod 302, making installation very convenient.
[0036] Of course, the leveling component can also be a spirit level, a leveling bubble, or other instruments that facilitate intuitive judgment of whether it is level. The purpose of these instruments is to deviate from the design concept of this utility model and they should fall within the protection scope of this utility model.
[0037] According to one embodiment provided by this utility model, such as Figure 1 and Figure 2 As shown, the ranging mechanism includes an infrared rangefinder 401, which is installed on the first rod 302. A reflector is provided at the end of the box girder, and the infrared rangefinder 401 cooperates with the reflector to measure distance.
[0038] In this embodiment, an infrared rangefinder 401 is installed on the first rod 302. The infrared rangefinder 401 can move synchronously with the first rod 302. That is, when the first rod 302 moves to a specified height position along the extension direction of the vertical plate 200, the infrared rangefinder 401 moves to the specified height accordingly. At this time, a reflector plate is provided at the end of the box girder to cooperate with the infrared rangefinder 401. By measuring the distance between the corrugated pipe 500 and the end of the box girder through the cooperation of the infrared rangefinder 401 and the reflector plate, the distance can be determined. The distance measurement by the infrared rangefinder 401 and the reflector plate has very high accuracy, thereby effectively eliminating errors and ensuring construction accuracy and efficiency.
[0039] According to one embodiment provided by this utility model, such as Figure 1 and Figure 2 As shown, an infrared emitter 402 is installed on the top wall of the third rod 304.
[0040] In this embodiment, in order to cooperate with the leveling mechanism, an infrared emitter 402 is installed on the top wall of the third rod 304. The infrared rays emitted by the infrared emitter 402 directly irradiate the corrugated pipe 500, so as to ensure that the construction personnel can intuitively judge the height of the horizontal telescopic rod 300 and the position of the corrugated pipe 500, which can effectively ensure construction efficiency.
[0041] Of course, the infrared emitter 402 can also be replaced by a laser emitter or other devices capable of emitting horizontal light. The purpose of these devices is not different from the design concept of this utility model, and they should be included in the protection scope of this utility model.
[0042] According to one embodiment provided by this utility model, such as Figure 1 As shown, the base 100 has three legs 101 at its bottom, and the three legs 101 are evenly spaced along the bottom surface of the base 100.
[0043] In this embodiment, three support legs 101 are provided at the bottom of the base 100. The three support legs 101 are distributed in a dispersed manner and are evenly spaced along the circumference of the bottom surface of the base 100. That is, the included angle between the projections of the three support legs 101 perpendicularly falling on the base 100 is 120°, which can ensure the stability of the base 100. In order to further ensure the stability of the base 100, a support column 102 is also provided at the center of the base 100. The end face of the support column 102 facing away from the base 100 is in contact with the fixed surface, and works with the support legs 101 to support the entire positioning and detection fixture.
[0044] Of course, the base 100 can also be sleeved on the outside of the vertical plate 200, and the base 100 can slide along the extension direction of the vertical plate 200, which can effectively increase the maximum height of the vertical plate 200. Preferably, a fourth spring bolt is provided at the connection between the base 100 and the vertical plate 200. When it is necessary to adjust the relative position of the vertical plate 200 and the base 100, the base can be slid along the extension direction of the vertical plate 200 by pressing the fourth spring bolt, so as to change the length of the vertical plate 200 above the base 100, thereby increasing the overall applicability of the positioning and detection fixture.
[0045] According to one embodiment provided by this utility model, such as Figure 1 and Figure 2 As shown, the vertical plate 200 has scale lines 201 along its own extension direction.
[0046] In this embodiment, scale lines 201 are arranged on the side wall of the vertical plate 200 along its extension direction. In order to ensure the height position accuracy of the corrugated pipe 500 to the greatest extent, the scale lines 201 are set to the millimeter level, that is, the minimum span of the scale lines 201 is millimeters. During use, the horizontal telescopic rod 300 is slid up and down according to the scale lines 201, and the construction personnel can directly observe the scale lines 201 to read the value to determine the height value of the corresponding corrugated pipe 500.
[0047] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
