Description

Technical Field

[0001] The present invention relates to the technical field of bridge construction equipment, in particular to a diamond-shaped hanging basket. Background Art

[0002] In the cantilever casting construction of bridges, the hanging basket is one of the key equipment. The diamond hanging basket is widely used due to its simple structure, reasonable force, and good stability. However, the existing diamond hanging basket still has some shortcomings: Problems with synchronization of hanging basket movement: During the forward movement of the hanging basket, the driving devices on the left and right sides are difficult to synchronize accurately, resulting in deviations, jams, and other phenomena during the movement of the hanging basket, affecting construction efficiency and safety.

[0003] The bottom basket height is inconvenient to adjust: When the bottom basket height needs to be adjusted, the operation process is complicated and the heights of multiple booms need to be adjusted in sequence, which consumes a lot of time and manpower. It is also difficult to ensure the consistency of the adjustment of each boom, affecting the construction accuracy.

[0004] Insufficient adaptability of the formwork system: For bridge segments of different shapes and sizes, the existing formwork system often requires a lot of modification and adjustment, and has poor versatility, which increases construction costs and time.

[0005] Insufficient adaptability of the formwork system: For bridge segments of different shapes and sizes, the existing formwork system often requires a lot of modification and adjustment, and has poor versatility, which increases construction costs and time. Summary of the Invention

[0006] The object of the present invention is to provide a diamond-shaped hanging basket to solve the problems raised in the above background technology.

[0007] Technical Solution Overall structure: This diamond hanging basket mainly includes walking anchor system, diamond truss system, suspension system, bottom basket system, template system and control system.

[0008] Travel anchoring system: It consists of two parallel rails, which are anchored by pre-rolled threaded steel bars embedded in the cast beam sections.

[0009] A traveling trolley is provided on the track, and a driving motor and a reducer are installed on the traveling trolley. The driving motor drives the traveling wheels to rotate through the reducer to realize the forward movement of the hanging basket.

[0010] A synchronous connecting rod is set between the traveling trolleys to ensure that the traveling trolleys on both sides move synchronously.

[0011] Diamond truss system: It consists of two diamond-shaped main trusses connected by a transverse connection system. The diamond-shaped main trusses are made of high-strength steel and have sufficient strength and rigidity.

[0012] Suspension system It includes an upper hanger and a lower hanger. One end of the upper hanger is connected to the diamond truss, and the other end passes through the cast beam section and is anchored to the bottom of the beam through a nut.

[0013] It includes an upper hanger and a lower hanger. One end of the upper hanger is connected to the diamond truss, and the other end passes through the cast beam section and is anchored to the bottom of the beam through a nut.

[0014] The base basket system consists of a base formwork, longitudinal beams, and cross beams. The base formwork is made of steel, ensuring sufficient flatness and strength. The longitudinal beams and cross beams are made of I-beams and connected by bolts to form a whole, providing support for the base formwork.

[0015] Formwork system: includes outer formwork, inner formwork and end formwork. The outer and inner formwork are connected to the bottom basket system via rails and can slide along the rails to achieve the installation and removal of the formwork.

[0016] The end formwork uses a modular formwork and is assembled according to the size of the bridge segment.

[0017] Control system: PLC control system is used to centrally control operations such as the movement of the hanging basket, bottom basket height adjustment, template installation and removal, etc.

[0018] The control system is equipped with sensors to monitor the operating status and stress conditions of the hanging basket in real time. If any abnormality occurs, it will automatically alarm and take corresponding protective measures.

[0019] Beneficial effects Improve movement synchronization: By setting up a synchronous link and PLC control system, the walking trolleys on both sides of the hanging basket can be ensured to move synchronously, avoiding deviation and jamming of the hanging basket during movement, thereby improving construction efficiency and safety.

Installation of hanging basket: Pre-embed the fine-rolled threaded steel bars on the cast beam section, install the track of the walking anchoring system, and anchor it.

[0021] Install the trolley on the track and connect the synchronous connecting rod.

[0022] Assemble the diamond truss system, connect the two diamond main trusses into a whole through the transverse connection system, and install it on the traveling trolley.

[0023] Install the upper and lower hangers of the suspension system, and suspend the bottom basket system under the diamond truss through the lower hanger.

[0024] Install the outer formwork, inner formwork and end formwork of the formwork system, adjust the position of the formwork and secure it.

[0025] Connect the control system lines and sensors for debugging.

[0026] Basket movement: Start the PLC control system to control the drive motor to work. The drive motor drives the travel wheel to rotate through the reducer, so that the basket moves forward along the track.

[0027] During the movement of the hanging basket, the synchronous connecting rod ensures that the walking trolleys on both sides move synchronously. The sensor monitors the operating status of the hanging basket in real time. If any abnormality occurs, the PLC control system will automatically alarm and stop the movement of the hanging basket.

[0028] Bottom basket height adjustment: According to construction needs, input bottom basket height adjustment instructions on the PLC control system.

[0029] The control system controls the electric wrench to rotate the connecting sleeve and adjusts the height of multiple lower booms at the same time to raise or lower the bottom basket to the specified position.

[0030] Formwork Installation and Removal: During formwork installation, the outer and inner forms are slid along the track to the designated position and then bolted to the base basket system. The end forms are assembled according to the size of the bridge segment and installed in the corresponding position.

[0031] When disassembling the formwork, first remove the end formwork, then loosen the connecting bolts between the outer and inner formwork and the bottom basket system, and slide the outer and inner formwork out along the track.

[0032] Construction monitoring: During the construction process of the hanging basket, sensors are used to monitor the stress, deformation, movement speed and other parameters of the hanging basket in real time, and the data is transmitted to the PLC control system.

[0033] The PLC control system analyzes and processes the monitoring data. If any abnormal data is found, an alarm signal will be issued in time, and corresponding measures will be taken, such as stopping the movement of the hanging basket and adjusting the height of the bottom basket, to ensure construction safety.
