Description

Technical Field

[0001] The utility model belongs to the technical field of construction engineering, and in particular relates to a large-span column suspended pouring hanging basket with suspension force monitoring. Background Art

[0002] During the construction of long-span bridges and buildings, suspended cast-in-place hanging baskets are crucial equipment. The stability of their suspension force directly impacts construction safety and the overall stability of the structure. Traditional suspension force testing equipment relies heavily on manpower and suffers from shortcomings such as low measurement accuracy, low efficiency, and susceptibility to environmental influences. Summary of the Invention

[0003] The main purpose of the utility model is to provide a large-span column suspended casting basket with suspension force monitoring. By arranging stress sensors on the suspension rods, the suspension force of the large-span column suspended casting basket is monitored in real time by using the stress sensors. The controller controls the operation of the alarm according to the monitoring data, which not only realizes the automatic monitoring of the suspension force of the basket, but also effectively improves construction safety and reduces the risk of accidents.

[0004] To this end, the utility model provides a large-span column suspended casting basket with suspension force monitoring, including a main truss, a front upper crossbeam, an outer sliding beam, a bottom form, a sliding beam bracket and a front hanger. The main truss is installed on the longitudinal movement track on the bridge deck, the front upper crossbeam is arranged on the front end of the main truss, and the sliding beam bracket is anchored in the concrete of the bridge deck. One end of multiple front hangers is fixedly connected to the front upper crossbeam, and the other end is connected to the bottom form. One end of the outer sliding beam is fixedly connected to the front hanger, and the other end is arranged in the sliding beam bracket. Each front hanger is provided with a stress sensor for monitoring the tension it is subjected to. The stress sensor is connected to a data receiver, and the data receiver and alarm are connected to a controller.

[0005] Specifically, the stress sensor is a magnetic flux sensor.

[0006] Specifically, the stress sensor is connected to the data receiver via wireless communication.

[0007] Compared with the existing technology, the utility model has the following beneficial effects: by adding a stress sensor to the front boom of the hanging basket, the stress sensor is used to perform real-time online monitoring of the suspension force applied to the front boom, and the monitored suspension force data is transmitted to the data receiver. The controller compares the received measured suspension force data with the preset suspension force threshold value and controls the operation of the alarm. This not only realizes the automatic monitoring of the suspension force of the hanging basket, improves the monitoring efficiency, and reduces the possibility of human error, but also can issue an early warning when the suspension force applied to the boom exceeds the preset threshold value, which can effectively improve construction safety and reduce the risk of accidents.

[0012] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0014] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of this utility model, "plurality" means two or more, unless otherwise specifically defined.

[0015] See also Figure 1 and Figure 2 A large-span column suspended casting hanging basket with suspension force monitoring includes a main truss 1, a front upper cross beam 2, an outer sliding beam 3, a bottom formwork 4, a sliding beam bracket 5 and multiple front hangers 6. The main truss 1 is installed on the longitudinal track 7 on the bridge deck, the front upper cross beam 2 is arranged on the front end of the main truss 1, the sliding beam bracket 5 is anchored in the concrete of the bridge deck 12, one end of each front hanger 6 is fixedly connected to the front upper cross beam 2, and the other end is connected to the bottom formwork 4, one end of the outer sliding beam 3 is fixedly connected to the front hanger 6, and the other end is arranged in the sliding beam bracket 5, each front hanger 6 is provided with a stress sensor 8 for online monitoring of the tension applied to the front hanger 6, the stress sensor 8 is connected to the data receiver 9, and the data receiver 9 and the alarm 11 are connected to the controller 10.

[0016] The aforementioned suspension force monitoring and alarm process for the large-span column suspended casting basket is as follows: When the basket is operating, the stress sensor 8 monitors the tension (suspension force) applied to each front suspension rod 6 in real time online and transmits the monitored suspension force data to the data receiver 9 for processing and storage. The controller 10 compares the measured suspension force data in the data receiver 9 with the preset suspension force threshold data. When the measured suspension force exceeds the preset suspension force threshold, the controller 10 sends a control signal to the alarm 11. Upon receiving the control signal, the alarm 11 issues a warning or alarm. The warning or alarm can be notified to relevant personnel via SMS, email, or app push notification. This allows relevant personnel to quickly take measures to adjust the balance of the basket to ensure safe and smooth construction. If the data is normal, no warning or alarm is issued. Furthermore, by comparing the tension applied to different front suspension rods 6, adjustments can be made to each front suspension rod 6 to ensure consistency in the acceptance status of each front suspension rod 6, thereby effectively ensuring the safe operation of the basket.

[0017] This utility model utilizes a stress sensor 8 disposed on a suspension rod to monitor the suspension force of a large-span column suspended pouring basket in real time. A controller 10 controls an alarm 11 based on the monitoring data, thereby not only automating the monitoring of the basket's suspension force but also effectively improving construction safety and reducing the risk of accidents. The stress sensor 8 can be connected to the data receiver 9 via wireless communication. This facilitates installation, as no physical wiring is required, requiring only a connection between devices.

[0018] It is understood that in practical applications, stress sensor 8 can be a magnetic flux sensor. The working principle of the magnetic flux sensor for measuring stress is as follows: the magnetic flux sensor consists of two copper coils, namely a primary coil and a secondary coil. A pulse current is applied to the primary coil. At the moment of power-on, the front suspension rod 6, which is inserted into the magnetic flux sensor, acts as an iron core. The presence of the iron core generates a transient current in the secondary coil, resulting in a transient voltage. The magnitude of the voltage generated by electromagnetic induction depends on the magnetic permeability of the iron core material, which in turn is related to the stress state of the iron core. Measurement is achieved based on the relationship between the induced voltage and stress.
