Abstract
Description
Technical Field
[0001] This utility model relates to the field of bridge construction technology, specifically a bridge construction hanging basket equipped with a monitoring machine. Background Technology
[0002] The main function of a bridge construction formwork is to provide a working platform: offering a stable working space for workers and machinery, and allowing it to move longitudinally along the bridge to adapt to the needs of different construction stages. During use, because the formwork is suspended on the outside of the bridge and its top is raised and lowered via pulleys, it is prone to swaying, especially in windy weather. Excessive swaying can easily lead to collisions with the bridge's outer wall, posing dangers not only to the formwork and construction personnel but also causing damage to the bridge's outer wall. Current solutions often involve installing buffer structures on the outside of the formwork to mitigate these issues. However, existing buffer devices are often limited to a certain range of force, resulting in insufficient protection and buffering in both calm and windy conditions, potentially leading to either over- or under-buffering effects.
[0003] Therefore, given the aforementioned problems, existing hanging baskets are designed to operate in conjunction with monitoring devices. In industrial production, building construction, and infrastructure development, monitoring devices typically refer to automated equipment used to collect, analyze, and report critical operational data in real time. They integrate sensor technology, the Internet of Things (IoT), big data analytics, and other advanced technologies to ensure process transparency, safety, and efficiency.
[0004] In response, this technical solution proposes a bridge construction formwork with a monitoring device. Utility Model Content
[0005] The purpose of this invention is to provide a bridge construction formwork with a monitoring device to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A bridge construction formwork with a monitoring device includes a connecting column installed on one side of the top of the formwork. A set of T-shaped buffer boxes are detachably installed on each vertical outer wall of the formwork. An adjustable buffer mechanism is installed inside the T-shaped buffer box. The adjustable buffer mechanism is electrically connected to the connecting column. The connecting column is used to detect the wind force at the location of the formwork in real time and then synchronously control the buffering force of the adjustable buffer mechanism.
[0008] The T-shaped buffer box is installed on the side wall of the hanging basket. A buffer base plate is installed on the side of the T-shaped buffer box facing the outer wall of the hanging basket. The buffer base plate is snap-fitted to the outer wall of the hanging basket. The other side of the T-shaped buffer box is set as an opening, and an adjustable buffer plate is telescopically installed inside the opening. The adjustable buffer plate is connected to an adjustable buffer mechanism facing the inside of the T-shaped buffer box. That is, according to the wind force detected by the connecting column around the hanging basket, the adjustable buffer mechanism is activated to control the initial length of the adjustable buffer plate extending to the outside of the opening. That is, the more it extends, the greater the impact force it can withstand, and vice versa.
[0009] The adjustable buffer mechanism includes multiple sets of evenly distributed main buffer springs installed on the inner wall of the adjustable buffer plate. The side of the main buffer springs away from the adjustable buffer plate is connected to a connecting plate parallel to the inner wall of the adjustable buffer plate. An elastic scissor bracket is provided on the side of the connecting plate away from the main buffer springs. A cylinder is connected to the side of the elastic scissor bracket away from the connecting plate through a scissor base plate. The cylinder is fixed on the inner wall of the T-shaped buffer box and is electrically connected to the connecting column. That is, the cylinder controls the lateral movement of the scissor base plate, thereby driving the elastic scissor bracket, the connecting plate, and the main buffer springs to move laterally, thereby adjusting the extension length of the adjustable buffer plate and thus controlling and adjusting the buffering force.
[0010] Compared with the prior art, the beneficial effects of this utility model are: by using a monitoring body to detect wind force and control the operation of the cylinder, and then combining the cylinder to adjust the extension position of the adjustable buffer plate, it is ensured that the outer side of the hanging basket is subjected to a suitable buffer force according to the wind force, thereby achieving effective protection of the hanging basket, while also improving energy efficiency and protection of the outer side of the bridge and the hanging basket.

[0020] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0021] Please see Figures 1-5A bridge construction formwork with a monitoring device includes a connecting column 11 installed on one side of the top of the formwork 10. A set of T-shaped buffer boxes 20 are detachably installed on each vertical outer wall of the formwork 10. An adjustable buffer mechanism is provided inside the T-shaped buffer box 20. The adjustable buffer mechanism is electrically connected to the connecting column 11. The connecting column 11 is used to detect the wind force at the location of the formwork 10 in real time and then synchronously control the buffering force of the adjustable buffer mechanism.
[0022] The T-shaped buffer box 20 is installed on the side wall of the hanging basket 10. A buffer base plate 18 is installed on the side of the T-shaped buffer box 20 facing the outer wall of the hanging basket 10. The buffer base plate 18 is snap-fitted to the outer wall of the hanging basket 10. The other side of the T-shaped buffer box 20 is set as an opening, and an adjustable buffer plate 23 is telescopically installed inside the opening. An adjustable buffer mechanism is connected to the interior of the T-shaped buffer box 20. That is, according to the wind force detected by the connecting column 11 around the hanging basket 10, the adjustable buffer mechanism is activated to control the initial length of the adjustable buffer plate 23 extending to the outside of the opening. That is, the more it extends, the greater the impact force it can withstand, and vice versa.
[0023] The adjustable buffer mechanism includes multiple sets of evenly distributed main buffer springs 27 installed on the inner wall of the adjustable buffer plate 23. The side of the main buffer springs 27 away from the adjustable buffer plate 23 is connected to a connecting plate 26 parallel to the inner wall of the adjustable buffer plate 23. An elastic scissor bracket is provided on the side of the connecting plate 26 away from the main buffer springs 27. A cylinder 24 is connected to the side of the elastic scissor bracket away from the connecting plate 26 through a scissor base plate 25. The cylinder 24 is fixed on the inner wall of the T-shaped buffer box 20 and is electrically connected to the connecting column 11. That is, the cylinder 24 controls the lateral movement of the scissor base plate 25, thereby driving the elastic scissor bracket, the connecting plate 26, and the main buffer springs 27 to move laterally, thereby adjusting the extension length of the adjustable buffer plate 23, thus realizing the control and adjustment of the buffering force.
[0024] In this embodiment of the invention, connecting columns 11 are installed at the four corners of the top of the hanging basket 10. Each connecting column 11 is connected to a cable 12 that is inclined towards the center of the top of the hanging basket 10. The top of the cable 12 is connected to a connecting ring 13. The top center of the connecting ring 13 is connected to the lifting device (here, it usually refers to the pulley lifting mechanism) through a steel wire rope 14, thereby controlling the lifting of the hanging basket 10.
[0025] A retaining strip 19 is installed on the middle of the outer side of the buffer base plate 18. A retaining groove 15 is opened on the outer side wall of the hanging basket 10 corresponding to the retaining strip 19. The retaining strip 19 is snapped into the retaining groove 15. At the same time, multiple through holes are evenly opened on the upper and lower side walls of the buffer base plate 18. Positioning screw holes 16 are opened on both sides of the retaining groove 15 corresponding to the through holes. By inserting threaded connection mounting bolts 22 into the through holes and positioning screw holes 16, the T-shaped buffer box 20 is securely installed on the outer side wall of the hanging basket 10.
[0026] In one embodiment of the present invention, it should be noted that the impact resistance of the outer side of the hanging basket 10 is controlled by adjusting the extension length of the adjustable buffer plate 23. This is mainly to prevent the adjustable buffer plate 23 from being extended outward excessively when a large buffering force is not required, which would increase the space occupied on the outer side of the hanging basket 10 and increase the contact frequency between the adjustable buffer plate 23 and the outer side of the bridge. Excessive contact will have a certain impact on the outer side of the bridge under construction, mainly referring to damage to the outer surface.
[0027] To prevent the outer side of the T-shaped buffer box 20 at the non-adjustable buffer plate 23 from contacting the bridge or other locations, a buffer layer 21 is provided on the outer wall of the T-shaped buffer box 20, thereby increasing the protection of the outer wall of the T-shaped buffer box 20 by using the buffer layer 21.
[0028] The corners of the hanging baskets 10 between the ends of adjacent T-shaped buffer boxes 20 are set as arc-shaped structures, and an arc-shaped protective sleeve 32 is laid on the outside of the arc-shaped structure to increase the protection of the corners.
[0029] In a preferred embodiment of the present invention, the elastic scissor lift bracket includes two sets of scissor plates 28 that are rotatably connected by a rotating shaft 29. Multiple auxiliary buffer springs 31 are evenly and elastically connected between the scissor plates 28 on both sides of the rotating shaft 29. At the same time, each end of the scissor plate 28 is connected to an end rod 30. The end rod 30 is rotatably connected to the corresponding scissor base plate 25 and connecting plate 26. That is, the elastic cross connection between the scissor plates 28 is used to swing and buffer the impact force from the connecting plate 26.
[0030] As a preferred embodiment of the present invention, the principle of controlling the adjustable buffer plate 23 to extend and retract according to the wind force by the monitoring body 17 can be divided into the following three steps:
[0031] (1) Wind sensing and signal conversion
[0032] Wind speed sensors (such as blade / ultrasonic anemometers or barometric pressure sensors) are used to collect wind signals in real time.
[0033] The sensor converts wind physical quantities into linear electrical signals (such as 4-20mA current signals or 0-5V voltage signals).
[0034] (2) Control system processing
[0035] The signal conditioning circuit filters / amplifies the original signal.
[0036] The controller (PLC or microcontroller) receives the processed signals and outputs control commands in the following ways:
[0037] Threshold control: Set a critical wind speed (e.g., 15 m / s), and if the limit is exceeded, cylinder 24 will be fully extended / retracted.
[0038] Proportional control: Outputs a continuous control quantity (e.g., 0-10V) that is positively correlated with wind speed via PWM or DA conversion.
[0039] (3) Pneumatic actuation response
[0040] The proportional solenoid valve receives control signals and precisely adjusts the compressed air flow.
[0041] High wind speed → large control quantity → increased solenoid valve opening → increased intake pressure in cylinder 24 → piston rod extension
[0042] Low wind speed → small control input → reduced solenoid valve opening → cylinder 24 exhaust pressure drop → piston rod retraction
[0043] The displacement sensor (optional) forms a closed-loop control system, providing real-time feedback on the piston position for dynamic correction.
[0044] That is, through the closed-loop control logic of "sensing → decision-making → execution", the 24th stroke of the cylinder forms a dynamic correspondence with the wind force intensity, taking into account both response speed and system stability.
[0045] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
