[0002] Precast box girder diaphragms are transverse connecting components installed in precast box girder structures. They are mainly used to enhance the transverse stiffness and overall stability of the box girder. The reinforcing bars in the precast box girder diaphragms usually need to be fixed by electric welding during installation.

[0003] Currently, electric welding is used to fix and install the reinforcing bars of precast box girder diaphragms quickly. However, it is inconvenient to limit the spacing between the reinforcing bars during the fixing and installation process, resulting in a large spacing between the reinforcing bars after welding. To solve this problem, a precast box girder diaphragm reinforcing bar installation device is needed to assist in limiting the spacing of the reinforcing bars during electric welding. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that when fixing and installing reinforcing bars, it is inconvenient to limit the spacing between the reinforcing bars of the precast box girder diaphragm, resulting in a large spacing between the reinforcing bars after electric welding. Therefore, a precast box girder diaphragm reinforcing bar installation device is proposed.

[0006] The limiting component includes a rotating block, one end of which is fixedly connected to a first bevel gear. One side of the first bevel gear is rotatably connected to the inner wall of the mounting housing. A second bevel gear is provided on the side wall of the first bevel gear. A bidirectional threaded rod is rotatably connected inside the mounting housing. A moving block is threadedly connected to the side wall of the bidirectional threaded rod. The bottom end of the moving block passes through a sliding groove. A limiting plate is fixedly connected to the bottom end of the moving block. A fixing frame is fixedly connected to the top end of the limiting plate. A cleaning rubber is fixedly connected in the fixing frame. A scale strip is provided on the top surface of the mounting housing. A transparent protective plate is fixedly connected to the top surface of the mounting housing.

[0011] As a further description of the above technical solution:

[0012] One end of the protective shell is provided with a round hole, and a rubber ring is fixedly connected in the round hole of the protective shell.

[0013] As a further description of the above technical solution:

[0021] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0022] 1. In this utility model, by setting a limiting component, during use, two steel bars are placed on one side of two limiting plates respectively. The rotating block is rotated according to the required spacing between the two steel bars, referring to the scale strip. The rotating block drives the first bevel gear, which in turn drives the second bevel gear, which drives the bidirectional threaded rod. The bidirectional threaded rod drives the moving block, thereby driving the limiting plates and adjusting the spacing between the two limiting plates. The adjusted limiting plates then limit the spacing between the two steel bars, preventing a large spacing after welding. After the limiting plates are in place, the limiting plates drive the fixing frame, which in turn drives the cleaning rubber. The cleaning rubber cleans the transparent protective plate, preventing impurities from adhering to the top surface of the transparent protective plate and affecting the visibility of the scale strip. This design, utilizing the bidirectional threaded rod, the moving block, and the limiting plates, facilitates the adjustment and limiting of the steel bar distance as needed, preventing a large spacing after welding. The cleaning rubber further cleans the transparent protective plate, preventing impurities from adhering to the top surface and affecting the visibility of the scale strip.

[0023] 2. In this utility model, by setting a fixing component, after adjusting the limiting plate, the electric push rod is activated. The electric push rod drives the clamping plate, which clamps and positions the rotating block, preventing the rotating block from rotating due to external factors, thus affecting the use of the limiting plate. After the device is used, when it is necessary to move the clamping plate back to its original position, the electric push rod drives the clamping plate back to its original position. The output shaft of the electric push rod is cleaned using a rubber ring to prevent impurities from adhering to the output shaft, thus avoiding additional cleaning work. Through this design, the electric push rod drives the clamping plate to clamp and position the rotating block, preventing the rotating block from rotating due to external factors, thus affecting the use of the limiting plate. The rubber ring is then used to clean the output shaft of the electric push rod to prevent impurities from adhering to the output shaft, thus avoiding additional cleaning work.

Detailed Implementation

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figures 1-4This utility model provides a technical solution: a precast box girder transverse diaphragm reinforcement installation device, including an installation shell 1 and a sliding groove 4. The bottom surface of the installation shell 1 is provided with the sliding groove 4, the middle of the installation shell 1 is provided with a limiting component 2, and the side of the installation shell 1 is provided with a fixing component 3.

[0032] The limiting component 2 includes a rotating block 21, one end of which is fixedly connected to a first bevel gear 22. One side of the first bevel gear 22 is rotatably connected to the inner wall of the mounting shell 1. A second bevel gear 23 is provided on the side wall of the first bevel gear 22. A bidirectional threaded rod 28 is rotatably connected inside the mounting shell 1. A moving block 24 is threadedly connected to the side wall of the bidirectional threaded rod 28. The bottom end of the moving block 24 passes through a sliding groove 4. A limiting plate 25 is fixedly connected to the bottom end of the moving block 24. A fixing frame 27 is fixedly connected to the top end of the limiting plate 25. A cleaning rubber 26 is fixedly connected in the fixing frame 27. A scale strip 29 is provided on the top surface of the mounting shell 1. A transparent protective plate 210 is fixedly connected to the top surface of the mounting shell 1. The limiting plate 25 is square. A groove is provided in the bidirectional threaded rod 28. A second bevel gear 23 is fixedly connected in the groove of the bidirectional threaded rod 28.

[0033] The specific implementation method is as follows: In use, two steel bars are placed on one side of the two limiting plates 25 respectively. According to the required spacing between the two steel bars, the rotating block 21 is rotated with reference to the scale strip 29. The rotating block 21 drives the first bevel gear 22, which drives the second bevel gear 23. The second bevel gear 23 drives the bidirectional threaded rod 28, which drives the moving block 24, thereby driving the limiting plate 25 to adjust the spacing between the two limiting plates 25. The adjusted limiting plate 25 limits the spacing between the two steel bars, avoiding a large spacing between the steel bars after welding. After the limiting plate 25 limits the spacing, the limiting plate 25 drives the fixing frame 27, which drives the cleaning rubber 26. The cleaning rubber 26 cleans the transparent protective plate 210, preventing impurities from adhering to the top surface of the transparent protective plate 210 and affecting the viewing of the scale strip 29 during use.

[0034] The fixing component 3 includes a protective shell 31, an electric push rod 32 is provided inside the protective shell 31, a round hole is provided at one end of the protective shell 31, a rubber ring 33 is fixedly connected in the round hole of the protective shell 31, the rubber ring 33 is circular, the output shaft of the electric push rod 32 passes through the rubber ring 33, a clamping plate 34 is fixedly connected to the output shaft of the electric push rod 32, one side of the protective shell 31 is fixedly connected to the side wall of the mounting shell 1, the clamping plate 34 is located outside the protective shell 31, and the protective shell 31 is located on one side of the mounting shell 1;

[0035] The specific implementation method is as follows: After adjusting the limiting plate 25, start the electric push rod 32, which drives the clamping plate 34 to clamp and position the rotating block 21, thus preventing the rotating block 21 from rotating due to external factors, which would affect the use of the limiting plate 25. After the device is used, when it is necessary to move the clamping plate 34 back to its original position, the electric push rod 32 is used to move the clamping plate 34 back to its original position. The rubber ring 33 is used to clean the output shaft of the electric push rod 32 to prevent impurities from adhering to the output shaft of the electric push rod 32 and increase the amount of cleaning work required.

[0036] Working principle: In use, two steel bars are placed on one side of the two limiting plates 25 respectively. The rotating block 21 is rotated according to the required spacing between the two steel bars, referring to the scale strip 29. The rotating block 21 drives the first bevel gear 22, which in turn drives the second bevel gear 23. The second bevel gear 23 drives the bidirectional threaded rod 28, which in turn drives the moving block 24, thereby driving the limiting plates 25. This adjusts the spacing between the two limiting plates 25, thus limiting the spacing between the two steel bars after welding. This prevents the spacing between the steel bars from becoming too large after welding. After the limiting plates 25 have reached their limit, they drive the fixing frame 27, which in turn drives the cleaning rubber. 26. Clean the transparent protective plate 210 by cleaning the rubber 26 to prevent impurities from adhering to the top surface of the transparent protective plate 210 and affecting the viewing of the scale strip 29 during use. After adjusting the limit plate 25, start the electric push rod 32. The electric push rod 32 drives the clamping plate 34 to clamp and position the rotating block 21, preventing the rotating block 21 from rotating due to external factors, which would affect the use of the limit plate 25. After the device is used, when it is necessary to move the clamping plate 34 back to its original position, the electric push rod 32 drives the clamping plate 34 back to its original position. Use the rubber ring 33 to clean the output shaft of the electric push rod 32 to prevent impurities from adhering to the output shaft of the electric push rod 32 and increase the amount of cleaning work required.
