Description

Technical Field

[0001] This utility model relates to the technical field of edge correction devices for steel box girders, specifically to an edge correction device for steel box girders. Background Technology

[0002] During the processing of steel box girders, the edges of the steel box girders are prone to deformation due to various factors such as welding stress and transportation collisions. Traditionally, the repair of steel box girder edge deformation mainly relies on manual operation, with workers using simple tools to perform correction operations such as hammering and pressing on the deformed parts.

[0003] Chinese Patent No.: CN219597725U, a steel box girder panel deformation correction device, comprising: a base and a moving component and a correction component disposed on the base. The base is disposed on the outer side of the web of the steel box girder. The correction component is fixed on the moving component and moves along the length direction of the base via the moving component. The correction component includes a first correction part, a second correction part, and a driving part. The first correction part is adapted to the upper side of the steel box girder panel and the inner sidewall of the web. The second correction part is adapted to the lower side of the steel box girder panel and the outer sidewall of the web. The first correction part and the second correction part are movably connected. The driving part is connected to the second correction part and is used to drive the second correction part to move toward the lower side of the steel box girder panel and cooperate with the first correction part to clamp the steel box girder panel and web. While fixing the web, it clamps and corrects the panel, effectively preventing web deformation during correction and ensuring correction accuracy.

[0004] The aforementioned patent also has some defects. If there are debris, dust, oil stains, etc. on the surface of the straightening plate during the straightening work, it may not be able to fit tightly with the steel box girder panel and web. This will prevent the straightening force from being evenly transmitted to the steel box girder, thereby affecting the accuracy and effect of the straightening, failing to achieve the ideal straightening state, and failing to guarantee that the straightening force can be evenly applied to the steel box girder. It may also cause the straightening plate to slip during the straightening process, reducing the straightening accuracy. Therefore, we need to propose a steel box girder edge straightening device.

[0025] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-6This utility model provides a technical solution: a steel box girder edge straightening device, including a steel box girder 1 and a movable frame 2. The steel box girder 1 is located above the movable frame 2. The movable frame 2 is internally equipped with a hydraulic component for height adjustment. The steel box girder 1 is an important structural component in bridge construction and other engineering projects. The movable frame 2 provides support and installation foundation for the entire straightening device, and can be flexibly moved by casters 20 at the bottom, facilitating the processing of the steel box girder 1 in different working scenarios, improving the ease of use and applicability of the device. The internal space can be used to install components such as a controller 21, making reasonable use of space and protecting internal components. Position movement is achieved by rolling on the ground using the casters 20. One end of the hydraulic component extends upward to the outside of the movable frame 2. The hydraulic assembly includes a hydraulic pump 3 and a hydraulic cylinder 4. The hydraulic pump 3 is installed inside the movable frame 2. The output end of the hydraulic pump 3 extends to the top of the movable frame 2 and is connected to the hydraulic cylinder 4. The piston of the hydraulic cylinder 4 is connected to the bottom of the straightening assembly. The hydraulic pump 3 is installed inside the movable frame 2. After starting, it draws hydraulic oil from the oil tank and other oil storage devices and pressurizes it. The high-pressure hydraulic oil is delivered to the hydraulic cylinder 4 through the oil pipe at the output end. There is a piston inside the hydraulic cylinder 4. After the high-pressure hydraulic oil enters the hydraulic cylinder 4, it pushes the piston to move upward. The piston's push rod is connected to the bottom of the second lower straightening plate 6 of the straightening assembly, thereby driving the entire straightening assembly to rise. When it is necessary to descend, the hydraulic pump 3 stops pressurizing, and the hydraulic oil in the hydraulic cylinder 4 flows back under the action of gravity and the gravity of the straightening assembly itself, realizing the descent of the straightening assembly.

[0027] A straightening assembly for straightening the edges of the steel box girder 1 is installed on top of the movable frame 2. One end of the straightening assembly is connected to one end of the hydraulic assembly. The straightening assembly includes a first upper straightening plate 5, a second lower straightening plate 6, and a vertical plate 7. The first upper straightening plate 5 and the second lower straightening plate 6 are connected by the vertical plate 7. The first upper straightening plate 5 and the second lower straightening plate 6 can simultaneously straighten the upper and lower edges of the steel box girder 1 to ensure the flatness of the edges of the steel box girder 1. The bottom of the second lower straightening plate 6 is connected to the push piston of the hydraulic cylinder 4. The first upper straightening plate 5 and the second lower straightening plate 6 are located at the upper and lower edges of the steel box girder 1 respectively and are parallel to each other. A groove 8 is formed on the surface of the vertical plate 7. Multiple sets of electric slides 9 are installed inside. The sliders of the electric slides 9 are connected to connecting columns 10. The end of the connecting column 10 away from the electric slides 9 is connected to one end of the first straightening upper horizontal plate 5. When the hydraulic cylinder 4 pushes the second straightening lower horizontal plate 6 to rise or fall, the second straightening lower horizontal plate 6 drives the first straightening upper horizontal plate 5 to move synchronously through the vertical plate 7, so that the first straightening upper horizontal plate 5 and the second straightening lower horizontal plate 6 are tightly attached to the upper and lower edges of the steel box girder 1 respectively. After the electric slides 9 in the groove 8 on the vertical plate 7 are started, their sliders slide along the groove 8, and drive the first straightening upper horizontal plate 5 to move horizontally through the connecting column 10, thereby applying a squeezing force to the edge of the steel box girder 1 and straightening the uneven edge to a flatness that meets the standard.

[0028] A steel brush assembly for cleaning the edge surface of the steel box girder 1 is installed on one side. The steel brush assembly includes a robotic arm 11 and a cleaning plate 12. The cleaning plate 12 can effectively remove impurities such as rust, oil, and dust from the edge surface of the steel box girder 1, improving the cleanliness of the edge of the steel box girder 1. This prevents the pressure transmission and adhesion effect of the first upper straightening plate 5 and the second lower straightening plate 6 on the edge of the steel box girder 1 from being affected, ensuring that the straightening force can be applied evenly to the steel box girder 1. The robotic arm 11 is symmetrically installed on both sides of the first upper straightening plate 5, and the cleaning plate 12 is installed at the end of the robotic arm 11 away from the first upper straightening plate 5. The bottom of the cleaning plate 12 is attached to the edge of the steel box girder 1. On the upper edge surface of the steel box girder 1, the robotic arm 11 is installed on both sides of the first straightening upper horizontal plate 5. Under the control of the controller 21, it can extend, retract, and rotate. When it is necessary to clean the edge of the steel box girder 1, the robotic arm 11 drives the cleaning plate 12 to move above the edge of the steel box girder 1. The bottom of the cleaning plate 12 is attached to the upper edge surface of the steel box girder 1. The robotic arm 11 moves along the edge of the steel box girder 1. The steel brush at the bottom of the cleaning plate 12 rubs against the edge surface of the steel box girder 1 to remove surface impurities. After the cleaning operation is completed, the robotic arm 11 drives the cleaning plate 12 to retract and rotate towards the top of the first straightening upper horizontal plate 5 to avoid interfering with the subsequent straightening process.

[0029] A cleaning assembly for spraying water onto the edge surface of the steel box girder 1 is installed on one side. The cleaning assembly includes a water tank 13, a water pump 14, an inlet pipe 15, and an outlet plate 16. The water tank 13 is used to store clean water, and the water pump 14 is used to provide power for conveying clean water. The water tank 13 is installed on the surface of the second straightening lower horizontal plate 6 and is located on the side of the vertical plate 7 away from the groove 8. The inlet end of the water pump 14 is connected to the water tank 13, and the outlet end of the water pump 14 is connected to one end of the inlet pipe 15. The outlet plate 16 is connected to the side of the first straightening upper horizontal plate 5 away from the vertical plate 7. The end of the inlet pipe 15 away from the water pump 14 is connected to the outlet plate 16. The outlet plate 16 is hollow, and multiple sets of inclined spray heads 17 are installed at the bottom of the outlet plate 16. The bottom of the spray heads 17 corresponds to the edge of the steel box girder 1. A motor 18 is installed on the surface of the first straightening upper horizontal plate 5. The output axis of the motor 18 is symmetrically mounted on... Equipped with a drive shaft 19, the other end of which is connected to the upper surface of the water outlet plate 16, the water pump 14 draws water from the water tank 13 and delivers it to the hollow water outlet plate 16 through the water inlet pipe 15. Multiple sets of angled spray heads 17 at the bottom of the water outlet plate 16 spray water at a certain angle, directly impacting the edge surface of the steel box beam 1, washing away the impurities remaining after cleaning by the cleaning plate 12. At the same time, the motor 18 is installed on the surface of the first straightening upper horizontal plate 5. After starting, the output shaft of the motor 18 drives the drive shaft 19, which is symmetrically connected to it, to rotate. The other end of the drive shaft 19 is connected to the upper surface of the water outlet plate 16. When the cleaning program is started, the motor 18 drives the drive shaft 19 to rotate downward, so that the spray head 17 is accurately aligned with the edge upper surface of the steel box beam 1 to perform the rinsing operation. After the cleaning process is completed, the motor 18 drives the drive shaft 19 to rotate upward and reset, ensuring that it does not affect other normal operating procedures of the straightening device.

[0030] The bottom of the movable frame 2 is equipped with casters 20, which give the movable frame 2 good mobility, allowing operators to easily move the entire device around the construction site and quickly reach the position where the steel box girder 1 needs to be treated, greatly improving work efficiency. The movable frame 2 is internally equipped with a controller 21. A thin-film sensor 22 is installed on the surface of the second lower straightening plate 6, and a position sensor 23 is installed on the surface of the first upper straightening plate 5. The controller 21 has a pre-programmed control program and is connected to the hydraulic components, straightening components, steel brush components, cleaning components, and various sensors via circuitry. It receives signals from the thin-film sensor 22 and the position sensor 23, such as the thin-film sensor 22 detecting the pressure between the straightening components and the steel box girder 1, and the position sensor 23 detecting the pressure between the straightening components and the steel box girder 1. Based on these signals and preset workflows and parameters, the controller 21 sends control commands to the actuators of each component, such as controlling the start and stop and flow rate of the hydraulic pump 3, the moving speed and position of the electric slide 9, the movement of the robotic arm 11, the power of the water pump 14, and the rotation speed of the motor 18. The position sensor 23 is installed on the surface of the first straightening upper horizontal plate 5. It detects the distance or relative position relationship between itself and the reference point by transmitting and receiving signals. When the first straightening upper horizontal plate 5 moves, the position sensor 23 monitors its position change in real time and converts the position information into an electrical signal and transmits it to the controller 21. Based on these position signals, the controller 21 issues corresponding control commands to the components such as the electric slide 9 that control the position of the first straightening upper horizontal plate 5, so as to achieve precise position control of the edge of the steel box girder 1.
