[0002] With the continuous development of bridge engineering in recent years, cap beam construction techniques have become increasingly mature and diverse. The traditional hoop method for cap beam construction has long been favored by construction companies due to its lightweight structure, the lack of extensive support, simplicity compared to other construction methods, strong adaptability, and short construction period.

Both construction platforms suffer from high material consumption and low construction efficiency. Furthermore, if the bridge is located in hazardous areas such as rivers, deep trenches, or soft soil and mud, foundation preparation is often required, resulting in high construction costs and safety risks.

[0023] As described in the background art, since there is a certain space between the inner side of the hanging basket platform and the pier column, the platform may slide during operation, reducing the safety of the operation.

[0024] Therefore, in order to solve the above technical problems existing in the prior art, the present invention provides the following embodiments.

[0025] Example 1: This embodiment provides a road and bridge safety construction system. Figure 1 As shown, the construction system includes: A hoisting unit 200, which is fixed to the top of the pier 100; A climbing frame 500, which is connected to a hoisting unit via a steel cable, and is driven by the hoisting unit to move along the axis of the pier column; A hanging basket 300, wherein the hanging basket is integrally mounted on the climbing frame; like Figure 4 As shown, the climbing frame includes: Fixed climbing frame 510; A movable climbing frame 520, wherein the movable climbing frame is pivotally connected to the fixed climbing frame; The fourth power device 530 drives the movable climbing frame to pivot so as to hold or release the pier column; like Figure 6As shown, the movable climbing frame includes a movable frame 521, on which a third running wheel 522 is installed. When the movable climbing frame hugs the pier column, the third running wheel abuts against the pier column.

[0026] In this embodiment, there are two groups of movable climbing frames, and the two groups of movable climbing frames are arranged on both sides of the fixed climbing frame opposite to each other. The two groups of movable climbing frames can be connected to the fixed climbing frame through the same connecting shaft. The fourth power device can be selected from a pneumatic cylinder, an electric cylinder, or a hydraulic cylinder, preferably a hydraulic cylinder. At this time, the fourth power device can be movably connected to the two groups of movable climbing frames respectively, and the rotation of the movable climbing frame can be driven by the telescopic movement of its telescopic rod.

[0027] For example, Figure 5 As shown, the fixed climbing frame may include: A main frame 511 on which the movable climbing frame is pivotally mounted; A third power device 512, which is fixedly mounted on the main frame; The second running wheel 513 is mounted on the third power device and is driven by the third power device to move along the radial direction of the pier column.

[0028] In this embodiment, the two groups of movable climbing frames can be coaxially installed on the main frame, and the third power device can be selected from a pneumatic cylinder, an electric cylinder, or a hydraulic cylinder, preferably a hydraulic cylinder.

[0029] When this embodiment is in use, the fourth power device drives the movable climbing frame to rotate so that the movable climbing frame approaches the pier until the third walking wheel abuts against the circumference of the pier, and the third power device drives the second walking wheel to move linearly so that the second walking wheel abuts against the circumference of the pier. The above processes are carried out simultaneously, and then the winch unit works to stretch or relax the steel cable to make the climbing frame move vertically linearly along the pier, and the hanging basket moves vertically linearly with the climbing frame.

[0030] This embodiment uses a pivotal connection structure between a fixed climbing frame and a movable climbing frame, in conjunction with the drive control of the fourth power device, to achieve active clamping and locking of the climbing frame to the pier column. Combined with the radial adjustment function of the second walking wheel 513 and the clamping abutment of the third walking wheel 522, radial support force can be provided for the hanging basket, thereby reducing the lateral shaking of the hanging basket during operation and improving the anti-overturning ability of the overall system.

[0031] In addition, if Figure 1 As shown, the construction system further includes a circular unit 400, which drives the hanging basket to move along the circumference of the pier.

The second track wheel is fixedly mounted on the hanging basket; The second power device 430 drives one or two groups of rollers of the second track wheel to rotate, so as to drive the second track wheel to move along the second track.

[0033] In addition, the circular track further includes a first track 411, which is arranged parallel to the second track, and has limiting grooves on the upper and lower surfaces of the first track; The circulating unit further includes a first track wheel 440 , which is arranged corresponding to the first track. Two groups of rollers of the first track wheel are arranged on the upper and lower sides of the first track and cooperate with the limiting grooves on the upper and lower surfaces of the first track.

[0034] In this embodiment, the first track and the second track are connected by a column, and the second power device can be a servo motor, a stepper motor or other device that can realize the rotation of the roller. The second power device can directly drive the roller to rotate, and can also be connected to a group of rollers or two groups of rollers through a reducer, a sprocket transmission mechanism or other transmission mechanism with power transmission function.

[0035] In addition, the circular track may further include: First power unit 414; The first running wheel 413 is mounted on the first power device and is driven by the first power device to move radially along the pier column.

[0036] In this embodiment, the first power device is fixedly installed on the column. The first power device can be a pneumatic cylinder, an electric cylinder, or a hydraulic cylinder, and a hydraulic cylinder is preferred.

[0037] In this embodiment, when the winch unit lifts the hanging basket to the preset construction height, if the hanging basket and the working point are offset in the horizontal position, the second power device can be started at this time, and the hanging basket can be driven by the second power device to move along the circular track, so that the hanging basket moves to the preset working point position, thereby realizing the "correction" of the hanging basket's working position; in this embodiment, the winch unit drives the climbing frame to move along the pier column axis, and the circular unit drives the hanging basket to move circumferentially along the pier column. The two cooperate to realize the axial and circumferential multi-degree-of-freedom movement of the hanging basket, so that the position of the hanging basket can be flexibly adjusted according to the requirements of the pier construction operation.

[0038] In this embodiment, if Figure 7 As shown, the construction system may further include a safety control 30, such as Figure 8 As shown, the security control module may include: The data receiving unit 31 is used to obtain the hoisting unit load data, the hanging basket inclination data, the wind speed, and the hoisting unit temperature and humidity data; The hoisting unit load monitoring unit 32 is used to calculate the actual hoisting unit load according to the wind speed and the hoisting unit load data to obtain the actual hoisting unit load calculation result; The temperature and humidity abnormality judgment unit 33 is used to judge the temperature and humidity abnormality according to the temperature and humidity data of the hoisting unit and obtain the temperature and humidity abnormality judgment result; The risk coefficient calculation unit 34 is used to calculate the risk coefficient based on the actual winch unit load calculation result, the temperature and humidity abnormality judgment result, the wind speed, and the basket inclination angle data to obtain the risk coefficient calculation result; The early warning unit 35 generates an early warning signal based on the risk coefficient calculation result, and sends the early warning signal to the alarm module 20 so that the alarm module performs an alarm action.

[0039] Specifically, the actual winch unit load is calculated as follows: ; in, N is the calculation result of the actual winch unit load, in Newton; N 0 is the load data of the winch unit, in Newton; ρ is the air density in kilograms per cubic meter; A is the windward area in square meters; v is the wind speed in meters per second.

[0042] For example, ω 1. ω 2. ω 3. ω 4 can be taken as 0.4, 0.35, 0.15, and 0.1 respectively; In addition, after obtaining the risk coefficient calculation result, the early warning unit performs risk level matching on the risk coefficient settlement result according to the risk level-risk coefficient matching table to obtain a risk level matching result. The risk levels can be divided into level I, level II, and level III from low to high; level I risk is low risk, level II risk is relatively high risk, and level III risk is high risk; after receiving the early warning signal, the alarm module warns through one or more of sound, light, text message or other warning signals. For example, at level I risk, the warning module can give a prompt by displaying a green light. At this time, the winch unit and the ring unit work normally. At level II risk, the warning module can give a prompt by displaying a yellow light. At this time, the winch unit and the ring unit reduce the operating speed. At level III risk, the warning module can give a warning through a red light and a buzzer sound prompt. At this time, the winch unit will lower the hanging basket to a safe height.

[0043] In this embodiment, the construction system may further include a sensing module 10, which may include an anemometer, a load sensor, a temperature and humidity sensor, an angle sensor, and the like. By placing the sensing module at preset locations on the hoist unit and the basket, the system can collect data such as the hoist unit's load, temperature and humidity, wind speed, and basket offset angle. The construction system may further include a monitoring unit 40, which can obtain data such as the hoist unit's load, temperature and humidity, wind speed, and basket offset angle in real time, as well as temperature and humidity anomaly determination results, actual hoist unit load calculation structure, risk factor calculation results, and risk level matching results. The monitoring unit can also input user instructions to generate control signals to the risk warning module.

[0044] In this embodiment, the risk warning module may further include a database 36 storing standard data such as a risk level-risk coefficient matching table, a threshold table, and a temperature and humidity anomaly judgment structure-temperature and humidity coefficient matching table.

[0045] This embodiment uses a risk coefficient calculation unit to map parameters such as load anomalies, temperature and humidity data, basket tilt offset and wind speed into a unified risk level, generate a graded warning signal, and thus achieve operation risk warning.

[0046] Example 2: This embodiment provides a road and bridge safety construction method, which uses the construction system described in Example 1 and includes: The fourth power device drives the movable climbing frame to rotate so that the movable climbing frame approaches the pier column until the third running wheel abuts against the circumference of the pier column, the third power device drives the second running wheel to move linearly so that the second running wheel abuts against the circumference of the pier column, and the first power device drives the first running wheel to move linearly so that the first running wheel abuts against the circumference of the pier column, and the above processes are carried out simultaneously; The winch unit works by stretching or loosening the steel cable to make the climbing frame move vertically along the pier, and the hanging basket moves vertically along with the climbing frame; After reaching the preset construction height, if the hanging basket and the working point are offset in horizontal position, the second power device is started to drive the hanging basket to move along the circular track through the power device so that the hanging basket moves to the preset working point position; When performing hanging basket operation, the safety control module obtains the hoisting unit load data, hanging basket inclination data, wind speed, and hoisting unit temperature and humidity data; Calculate the actual hoist unit load based on the wind speed and hoist unit load data to obtain the actual hoist unit load calculation result; Specifically, the actual winch unit load is calculated as follows: ; in, N is the calculation result of the actual winch unit load, in Newton; N 0 is the load data of the winch unit, in Newton; ρ is the air density in kilograms per cubic meter; A is the windward area in square meters; v is the wind speed in meters per second.

[0048] In this embodiment, the relationship between the above weights is as follows:

[0049] For example, ω 1. ω 2. ω 3. ω 4 can be taken as 0.4, 0.35, 0.15, and 0.1 respectively; An early warning signal is generated based on the risk coefficient calculation result, and the early warning signal is sent to the alarm module so that the alarm module executes the alarm behavior.

[0050] After obtaining the risk coefficient calculation result, the early warning unit matches the risk coefficient settlement result with the risk level according to the risk level-risk coefficient matching table to obtain the risk level matching result. The risk levels can be divided into level I, level II, and level III from low to high; level I risk is low risk, level II risk is relatively high risk, and level III risk is high risk; after receiving the early warning signal, the alarm module warns through one or more of sound, light, text message or other warning signals. For example, at level I risk, the warning module can give a prompt by displaying a green light. At this time, the winch unit and the annular unit work normally. At level II risk, the warning module can give a prompt by displaying a yellow light. At this time, the winch unit and the annular unit reduce the operating speed.

The first power device drives the first running wheel to move linearly so that the first running wheel abuts against the circumference of the pier column. The above processes are carried out simultaneously. The winch unit works by stretching or loosening the steel cable to make the climbing frame move vertically along the pier, and the hanging basket moves vertically along with the climbing frame; After reaching the preset construction height, if the hanging basket and the working point are offset in horizontal position, the second power device is started to drive the hanging basket to move along the circular track through the power device so that the hanging basket moves to the preset working point position; When performing hanging basket operation, the safety control module obtains the hoisting unit load data, hanging basket inclination data, wind speed, and hoisting unit temperature and humidity data; Calculate the actual hoist unit load based on the wind speed and hoist unit load data to obtain the actual hoist unit load calculation result; Perform temperature and humidity anomaly judgment based on the temperature and humidity data of the winch unit to obtain the temperature and humidity anomaly judgment result; The risk coefficient is calculated based on the actual winch unit load calculation results, temperature and humidity anomaly judgment results, wind speed, and basket inclination data to obtain the risk coefficient calculation results; An early warning signal is generated based on the risk coefficient calculation result, and the early warning signal is sent to the alarm module so that the alarm module executes the alarm behavior.
