As an indispensable key equipment in cantilever construction, the bridge hanging basket faces unprecedented challenges in such sandstorm environment.

[0003] With the gradual progress of technology, some simple anchoring monitoring methods are applied to bridge construction, but in the sandstorm environment, these methods still have many defects. The early anchoring monitoring device mostly adopts bare sensor, which is directly installed in the anchoring part of the hanging basket. In the sandstorm environment, fine sand particles can easily enter the inside of the sensor and adhere to the sensitive element of the sensor. This not only interferes with the accurate measurement of the anchoring force of the sensor, causes the measurement data to deviate and fluctuate, but also accelerates the wear of the sensor in the long run, shortens its service life, frequently interrupts the monitoring work, and seriously affects the construction progress and quality.

Specific implementation

[0026] The technical scheme in the embodiments of the utility model will be apparently and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the scope of protection of the utility model.

[0027] Reference Figs. 1-3 An embodiment provided by the utility model: a bridge hanging basket with an anchor monitoring device, including walking track 1, the one end of walking track 1 is installed with rear anchor beam 2, the outer wall one side of rear anchor beam 2 is installed with anchor monitoring mechanism, it is used to carry out real-time monitoring to the anchoring force variation of hanging basket, the outer wall one side of walking track 1 is installed with lower chord 3, the one end of lower chord 3 is installed with vertical rod 4 and front inclined rod 5, the other end of lower chord 3 is installed with main truss 6, the outer wall one side of main truss 6 is installed with stress monitoring mechanism;

[0028] Anchor monitoring mechanism includes anchoring force sensor 7, anchoring force sensor 7 is installed in the outer wall one side of rear anchor beam 2, the outer wall one side of anchoring force sensor 7 is installed with protective net cover 8, it is used to resist the sand of external environment, the outer wall one side of protective net cover 8 is installed with self-cleaning assembly;

[0029] Self-cleaning assembly includes mounting seat 10, mounting seat 10 is fixedly connected in the bottom of protective net cover 8, the outer wall one side of mounting seat 10 is rotatably connected with the one end of long rod 11, the other end of long rod 11 is installed with blade 12, the outer wall of long rod 11 is connected with nut 13, the outer wall of nut 13 is installed with the one end of extension rod 14, the other end of extension rod 14 penetrates mounting seat 10;

[0030] The other end of the extension rod 14 is fixedly connected with an enlarged plate 16;

[0031] The other end of the extension rod 14 is fixedly connected with an enlarged plate 16;

[0032] Specifically, when the protective screen cover 8 accumulates a certain amount of sand and dust, the blade 12 drives the rotating long rod 11, since the long rod 11 is rotationally connected with the mounting seat 10, and the inner part of the long rod 11 and the mounting seat 10 is fixedly connected with the two ends of the spring 15 respectively, rotating the long rod 11 will cause the spring 15 to elastically deform and store energy. The outer wall of the long rod 11 is threadedly connected with the nut 13, and as the long rod 11 rotates, the nut 13 will move along the axial direction of the long rod 11. The outer wall of the nut 13 is installed with one end of the extension rod 14, and the other end of the extension rod 14 penetrates through the mounting seat 10 and is fixedly connected with the enlarged plate 16. When the nut 13 moves, it will drive the extension rod 14 and the enlarged plate 16 to move together. During the movement of the enlarged plate 16, it will knock the surface of the protective screen cover 8, knocking off the sand and dust attached to the protective screen cover 8. When the long rod 11 stops rotating, the elastic potential energy stored in the spring 15 will be released, driving the long rod 11 to rotate in the opposite direction, so that the nut 13, the extension rod 14 and the enlarged plate 16 are reset, ready for the next cleaning. The blade 12 is installed at the other end of the long rod 11. During the rotation of the long rod 11, the blade 12 will generate a certain airflow, which will help blow the scraped sand and dust away from the protective screen cover 8, further improving the cleaning effect.

[0033] The stress monitoring mechanism includes a stress sensor 9, which is installed on one side of the outer wall of the main truss 6. The output end of the stress sensor 9 is electrically connected with an alarm component;

[0034] The alarm component includes a buzzer 17 and a flashing light 18. The input end of the buzzer 17 and the flashing light 18 is electrically connected with a photovoltaic panel 19.

[0035] Specifically, the stress sensor 9 is installed on one side of the outer wall of the main truss 6, which can monitor the stress change of the main truss 6 in the construction process in real time. The stress sensor 9 usually adopts strain gauge type or piezoresistive type sensing principle inside. When the main truss 6 is subjected to external force and stress changes, the sensitive element of the stress sensor 9 will deform, causing the electrical parameters to change, thereby converting the stress change into an electrical signal output. When the main truss 6 bears different stresses due to the movement of the hanging basket, concrete pouring and other construction operations, the stress sensor 9 can timely capture these changes and convert them into corresponding electrical signals.

[0036] The alarm component is composed of a buzzer 17 and a flashing light 18, and the input end thereof is electrically connected with a photovoltaic panel 19. The photovoltaic panel 19 can convert solar energy into electric energy to provide power support for the alarm component. When the stress sensor 9 monitors that the stress value of the main truss 6 exceeds the preset safety threshold, a signal is transmitted to the alarm component. At this time, the buzzer 17 will issue a loud sound alarm to attract the attention of the construction personnel; at the same time, the flashing light 18 will start to flash to further remind the on-site personnel with a prominent visual signal.

[0037] Working principle: the walking track 1 provides basic support and guidance for the hanging basket movement, and the rear anchor beam 2 installed at one end bears the key components of the anchoring monitoring mechanism. The anchoring force sensor 7 is installed on one side of the outer wall of the rear anchor beam 2, and when the anchoring force of the hanging basket changes due to the construction process and load variation, the sensitive elements in the sensor, such as strain gauges, will deform, change the resistance value, and convert into an electric signal output through the measurement circuit, which can reflect the change of the anchoring force in real time. The protective cover 8 is installed on the outer wall of the anchoring force sensor 7, and the carefully designed mesh can effectively block the wind and sand from entering the sensor and affecting the accuracy and service life, while not hindering the transmission of the anchoring force. The self-cleaning component: when the dust accumulates on the surface of the protective cover 8, the long rod 11 rotates with the blade 12. Since the long rod 11 is rotationally connected with the mounting seat 10 and there is a spring 15 between them, rotation causes the spring 15 to elastically deform and store energy, which drives the extension rod 14 and the enlarged plate 16 connected thereto to move, and the enlarged plate 16 scrapes the surface of the protective cover 8 to knock off the dust. After the long rod 11 stops rotating, the spring 15 releases the elastic potential energy to drive the long rod 11 to rotate in the opposite direction, so that the nut 13, the extension rod 14 and the enlarged plate 16 are reset. The airflow generated by the blade 12 at the other end of the long rod 11 during rotation blows away the knocked-off dust, enhancing the cleaning effect. The lower chord 3 on one side of the outer wall of the walking track 1, the vertical rod 4 and the front inclined rod 5 installed at one end thereof, and the main truss 6 installed at the other end thereof together form a stable structure. The stress sensor 9 on one side of the outer wall of the main truss 6 uses strain gauge or piezoresistive principle, and when the main truss 6 is subjected to stress changes due to the movement of the hanging basket and concrete pouring, the sensitive elements thereof deform, change the electrical parameters, and convert into an electric signal output to monitor the stress changes in real time. The alarm component is composed of a buzzer 17 and a flashing light 18, and the input end thereof is electrically connected with a photovoltaic panel 19. The photovoltaic panel 19 can convert solar energy into electric energy to provide power support for the alarm component. When the stress sensor 9 monitors that the stress value of the main truss 6 exceeds the preset safety threshold, a signal is transmitted to the alarm component. At this time, the buzzer 17 will issue a loud sound alarm to attract the attention of the construction personnel; at the same time, the flashing light 18 will start to flash to further remind the on-site personnel with a prominent visual signal.
