Description

Technical Field

[0001] The utility model belongs to the technical field of hanging basket deformation monitoring, in particular to a torsional deformation monitoring system for a suspended pouring hanging basket. Background Art

[0002] The hanging basket construction method requires the hanging basket to be hung on the box girder. Its sturdiness and installation smoothness directly affect the smoothness of the box girder during construction. Therefore, a hanging basket deformation monitoring device is required to monitor the hanging basket to ensure its safe operation, construction safety, and project quality. Currently, traditional hanging basket deformation monitoring is performed manually using measuring tools (such as levels and rangefinders). While simple, this method is inefficient, subject to large errors, and difficult to achieve real-time monitoring. While monitoring with optical equipment such as total stations can improve measurement accuracy, the equipment is expensive and complex to operate. Summary of the Invention

[0003] The main purpose of the utility model is to provide a torsional deformation monitoring system for a suspended pouring basket. By arranging two sets of laser ranging components on the upper chord of the suspended pouring basket, the displacement difference change obtained by the two sets of laser ranging sensors is used to analyze whether the upper chord of the basket maintains balance, thereby achieving the purpose of indirectly monitoring the torsional deformation of the basket.

[0004] To this end, the utility model provides a torsional deformation monitoring system for a suspended casting basket, comprising two groups of laser ranging components respectively arranged on the front and rear ends of the top of the upper chord of the suspended casting basket, each group of laser ranging components comprising a laser ranging sensor and a reflector; the laser ranging sensor and the reflector are respectively arranged on both sides of the upper chord, wherein the reflecting surface of the reflector is a stepped surface and is aligned with the laser ranging sensor, and the bottom of the laser ranging sensor and the reflector are both provided with a leveling base.

[0005] Specifically, it also includes a data receiver and a cloud database, the laser ranging sensor is connected to the data receiver, and the data receiver is connected to the cloud database.

[0006] Specifically, the two groups of laser ranging components are symmetrically arranged on the upper chord of the suspended casting basket.

[0007] Compared with the existing technology, the utility model has the following beneficial effects: by arranging two groups of laser ranging components on the upper chord of the suspended casting basket, the laser ranging sensor emits laser to the reflecting surface. When the basket is torsionally deformed, the propagation distance of the laser beam changes.

[0013] 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.

[0015] 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.

[0016] See also Figure 1-Figure 3 , a torsional deformation monitoring system for a suspended pouring basket includes two groups of laser ranging components, which are symmetrically arranged on the front and rear ends of the top of the upper chord 1 of the diamond-shaped suspended pouring basket. The diamond-shaped suspended pouring basket consists of an upper chord 1, a front oblique bar 2, a rear oblique bar 3, a lower chord 4 and a vertical bar 7. The two ends of the front oblique bar 2 are respectively connected to the front ends of the upper chord 1 and the lower chord 4, and the two ends of the rear oblique bar 3 are respectively connected to the rear ends of the upper chord 1 and the lower chord 4. The two ends of the vertical bar 7 are respectively connected to the rear end of the upper chord 1 and the front end of the lower chord 4. Each group of laser ranging components includes a laser ranging sensor 5 and a reflector 6. The laser ranging sensor 5 and the reflector 6 are respectively arranged on both sides of the upper chord 1, wherein the reflecting surface of the reflector 6 is a stepped surface and is aligned with the laser ranging sensor 5 to ensure that the laser emitted by the laser ranging sensor 5 can hit the reflector 6.

[0017] In this embodiment, one group of laser ranging components is arranged at the front end of the upper chord rod 1 of the suspended pouring basket, and the other group is arranged at the rear end of the upper chord rod 1 of the suspended pouring basket. The laser ranging sensor 5 emits laser to the reflecting surface and performs non-contact measurement based on the return signal. When the hanging basket undergoes torsional deformation, the vertical displacement of the hanging basket changes, and the propagation distance of the laser beam changes. The displacement difference change obtained by the two groups of laser ranging sensors 5 is used to analyze whether the upper chord rod 1 of the hanging basket maintains balance, thereby achieving the purpose of indirectly automatically monitoring the torsional deformation of the hanging basket.

[0018] See also Figure 1 and Figure 3 To facilitate leveling of the laser rangefinder 5 and reflector 6 during installation, they are placed on the top surfaces of the upper chord 1 on the upstream and downstream sides of the basket, respectively, using leveling bases 8. Before installation, the basket must be balanced and adjusted. Once the basket is balanced, installation and calibration are performed. The laser rangefinder 5 and reflector 6 are installed parallel and aligned on the same horizontal plane, with the straight line connecting their installation locations perpendicular to the upstream and downstream sides of the diamond-shaped basket.

[0019] See also Figure 1It is understood that in an actual design, the monitoring system may also include a data receiver 9 and a cloud database 10. The laser ranging sensor 5 is connected to the data receiver 9, which transmits signals to the cloud database 10. When the basket undergoes torsional deformation, the laser ranging sensor 5 transmits the distance data measured by the laser ranging sensor 5 before and after the torsional deformation to the data receiver 9. The data receiver 9 transmits the data signal to the cloud database 10. The cloud database 10 processes the distance data to obtain the displacement change of the basket before and after the torsional deformation and compares it with the pre-stored displacement value. If the measured displacement change value exceeds the pre-stored value, the cloud database 10 issues a warning or alarm. After the laser ranging sensor 5 and reflector 6 are installed and calibrated on the leveling base 8, multiple trial lifts are required for analysis. Due to the trapezoidal receiving surface structure of the reflector 6, the propagation distance between the laser ranging sensor 5 and the reflector 6 changes when the basket undergoes torsional deformation. This creates a cloud database 10, facilitating real-time cloud monitoring. The sensor transmits data to the cloud database 10 via a wireless network, enabling remote monitoring. The high precision and high resolution of the laser distance measuring sensor 5 can obtain deformation data with higher precision.

[0020] The cloud database 10 sets a displacement safety threshold based on the displacement change corresponding to the torsional deformation threshold preset by the project. When the displacement data from both the first and second groups of analysis are less than the set threshold, the database outputs a level 1 warning. When only one of the displacement data from the first and second groups of analysis is greater than the set threshold, the database outputs a level 2 warning. When both the displacement data from the first and second groups of analysis are greater than the set threshold, the database outputs a level 3 warning. When the output is a level 2 warning or a level 3 warning, the cloud database 10 sends an alert to relevant personnel via email, text message, or other means to ensure a timely response.
