[0002] In the construction of modern high-rise buildings, bridge towers, and other large concrete structures, climbing formwork technology has become one of the mainstream formwork construction techniques due to its advantages such as high construction efficiency, strong safety, and good adaptability. The climbing formwork system realizes the overall lifting and lowering of the formwork through hydraulic drive. The accuracy of its stroke control is directly related to the construction quality and safety. If the stroke is not in place, it may lead to deviations in formwork splicing and affect the accuracy of concrete forming; if the stroke is too far, it may cause risks such as equipment overload, structural stress imbalance, and even safety accidents.
[0003] Traditional hydraulic jacking for climbing formwork requires manual visual inspection to check whether the cylinders have reached the correct position. This means that personnel need to walk on the formwork during the climbing process, which is time-consuming and prone to incomplete inspections. The jacking process is unsafe and inefficient. Therefore, we need to propose a climbing formwork stroke completion detection device. Utility Model Content

Detailed Implementation
[0021] 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.
[0022] Please see Figure 1-5 This utility model provides a technical solution: a climbing formwork stroke completion detection device, including a main support vertical frame 1, a main support horizontal frame 3 bolted to the top of the main support vertical frame 1, an extension seat 4 welded to one side of the main support vertical frame 1, a reversing box 1 5 bolted to the bottom of the extension seat 4, a hydraulic cylinder 6 bolted to the bottom of the reversing box 1 5, a reversing box 2 7 bolted to the output end of the hydraulic cylinder 6, a stroke detection structure 2 for detecting the cylinder's lifting position on the inner side wall of the main support vertical frame 1, a trigger plate 8 for triggering the detection position on the stroke detection structure 2, and the trigger plate 8 bolted to the output end of the hydraulic cylinder 6;
[0023] The hydraulic cylinder 6 is connected to a telescopic button via a power cord to control the extension and retraction of the output end of the hydraulic cylinder 6.
[0024] When hydraulic cylinder 6 is activated, its output end extends or retracts, causing the reversing box 7 to move. The trigger plate 8, fixed to the output end of hydraulic cylinder 6, moves along with it. When the trigger plate 8 moves and triggers the stroke detection structure 2 on the inner wall of the main support frame 1, the stroke completion detection is completed, and the completion signal is transmitted to the electrical control system. The operator can then see the extension and retraction status of each machine position cylinder on the central control panel. Through the above scheme, during the climbing formwork lifting process, personnel do not need to walk on the climbing formwork frame for manual visual inspection, which improves the safety and efficiency of the lifting process.
[0025] The stroke detection structure 2 includes a stroke detection plate 21, which is fixed to the inner wall of the main support frame 1 by bolts. Both the upper and lower ends of the stroke detection plate 21 are rotatably connected to stroke detection switches, and the two sets of stroke detection switches are located on both sides of the trigger plate 8. The stroke detection plate 21 is fixed to the inner wall of the main support frame 1, and the stroke detection switches at its upper and lower ends correspond to the upper and lower limits of the hydraulic cylinder 6's lifting position, respectively. The stroke detection switch at the top of the stroke detection plate 21 is set as a stroke detection switch 22 for detecting the retraction of the push rod, and the stroke detection switch at the bottom of the stroke detection plate 21 is set as a stroke detection switch for detecting the extension of the push rod. Switch 23 triggers the upper push rod retraction detection limit switch 22 when the hydraulic cylinder 6 drives the trigger plate 8 to retract to the upper limit position; when the hydraulic cylinder 6 drives the trigger plate 8 to extend to the lower limit position, it triggers the lower push rod extension detection limit switch 23. Both sets of detection limit switches are connected to the electrical control system through signal lines. The operator can see the extension and retraction status of each machine position cylinder on the central control panel, thereby sensing whether the cylinder has been raised to the correct position. The two sets of detection limit switches are located on both sides of the trigger plate 8, which can accurately detect the upper and lower limit positions of the cylinder lifting, realize automatic sensing of the stroke completion, and reduce the error of manual monitoring.
[0026] The electronic control system mentioned in this embodiment is a very common existing technology in circuits. It does not impose any further protection or limitations on the electronic control system. The electronic control system can be modified according to actual needs.
[0027] The top of the travel detection plate 21 is integrally formed with a protective plate 9 for protecting the travel switches. The protective plate 9 is arranged in a U-shape. The protective plate 9 surrounds the two sets of travel switches, which can prevent external debris and collisions during construction from affecting the travel switches. The U-shaped design can protect the travel switches in all directions, extend the service life of the travel switches, ensure their detection sensitivity, and ensure the stability and reliability of travel detection.
[0028] A hydraulic pump station 10 is bolted to the outer wall of the main support frame 1. The hydraulic oil pipe of the hydraulic pump station 10 is connected to the connection port of the hydraulic cylinder 6. The hydraulic pump station 10 provides a power source for the hydraulic cylinder 6. By controlling the output and recovery of hydraulic oil, the hydraulic cylinder 6 is driven to extend and retract, thereby realizing the lifting and lowering action of the climbing formwork. The hydraulic pump station 10 is directly connected to the hydraulic cylinder 6. The hydraulic transmission efficiency is high, which can provide stable power to the hydraulic cylinder 6, ensure the smoothness of the cylinder extension and retraction action, and thus ensure the smoothness of the climbing formwork lifting and lowering process. At the same time, the hydraulic pump station 10 is connected to the power supply equipment through a power line.
[0029] The extension seat 4 is provided with a guide rail 11 at the end away from the main support frame 1. The two ends of the guide rail 11 are respectively provided with mounting bracket 12 and mounting bracket 2 13. Mounting bracket 12 is bolted to the surface of the extension seat 4, and mounting bracket 2 13 is bolted to the bottom end of the main support frame 1. The surfaces of reversing box 1 5 and reversing box 2 7 are provided with sliding grooves 14 that are adapted to the guide rail 11. When the output end of the hydraulic cylinder 6 drives the reversing box 2 7 to move, the sliding grooves 14 on the reversing box 2 7 slide along the guide rail 11, which guides the movement of the reversing box 2 7 on the guide rail 11. Through the cooperation of the guide rail 11 and the sliding grooves 14, the movement trajectory of reversing box 1 5 and reversing box 2 7 is restricted, ensuring that they move smoothly along a straight line, avoiding deviation or shaking during movement, and improving the stability of the device operation.
[0030] The guide rail 11 is I-shaped, and the inner cavity of the mounting bracket 12 is rotatably connected to a guide wheel 15 that assists in the movement of the guide rail 11. The surface of the guide wheel 15 is in contact with the inner wall of the guide rail 11. The I-shaped design of the guide rail 11 increases the contact area between the guide rail 11 and the slide groove 14, improving guiding stability. The I-shaped guide rail 11 has high structural strength, is not easily deformed, and can withstand large lateral forces. With the guide wheel 15, when the position of the guide rail 11 needs to be adjusted, pulling the guide rail 11 allows the guide wheel 15 to rotate with the movement of the guide rail 11, reducing the frictional resistance between the guide rail 11 and the mounting bracket 12. The guide wheel 15 converts sliding friction into rolling friction, reducing the resistance when the guide rail 11 moves, making the device operate more smoothly, and reducing the wear of the guide rail 11 and the mounting bracket, thus extending the service life of the components.
[0031] A bidirectional damping device 16 is installed on the outer wall of the main support vertical frame 1. Both ends of the bidirectional damping device 16 are rotatably connected to connecting frames via pivot pins. The two sets of connecting frames are welded and fixed to the outer wall of the support vertical frame and the bottom end of the main support horizontal frame 3, respectively. When the climbing formwork vibrates during the lifting process, the bidirectional damping device 16 absorbs and buffers the vibration energy through its own expansion and damping action, reducing the impact of vibration on the main support vertical frame 1 and the main support horizontal frame 3. By cooperating with the bidirectional damping device 16, the vibration during the climbing formwork operation is reduced, thereby reducing the damage of vibration to the connection structure of various components of the device, improving the overall seismic performance and stability of the device, extending the service life of the device, and ensuring construction safety.
[0032] In practical use: First, start the hydraulic pump station 10, which provides power to the hydraulic cylinder 6 via the hydraulic oil pipe. Then, control the telescopic button to move the output end of the hydraulic cylinder 6, which in turn moves the reversing box 7. The reversing box 7 moves on the surface of the guide rail 11 via the slide groove 14. The cooperation between the reversing box 7 and the guide rail 11 supports the movement of the output end of the hydraulic cylinder 6, improving the stability of the hydraulic cylinder 6 during movement and preventing the output end of the hydraulic cylinder 6 from shifting position. When the output end of the hydraulic cylinder 6 moves, it simultaneously drives the trigger plate 8 to move. When the trigger plate 8 retracts to the upper limit position... The upper push rod retraction detection limit switch 22 is triggered, and the push rod retraction detection limit switch 22 transmits the arrival signal to the electrical control system through the signal line. When the hydraulic cylinder 6 drives the trigger plate 8 to extend to the lower limit position, the lower push rod extension detection limit switch 23 is triggered, and the push rod extension detection limit switch 23 transmits the arrival signal to the electrical control system through the signal line. The operator can see the extension and retraction status of each machine position cylinder on the central control. With the above scheme, during the climbing formwork lifting process, personnel do not need to walk on the climbing formwork frame for manual visual inspection, which improves the safety and efficiency of the lifting process.
