[0002] In order to ease traffic congestion or match other municipal facilities planning, some urban road bridges or viaducts need to be renovated to increase their height to meet the requirements of lower cross-line traffic and navigation. The service life of a bridge is generally several decades. If the bridge is dismantled and rebuilt, it will not only waste resources, but also have a great impact on the surrounding environment and traffic. In this case, the use of bridge jacking technology can achieve the purpose of increasing the height of the bridge at a lower cost and a shorter construction period, and obtain good economic results.
[0003] Bridge jacking technology is an engineering technology that requires high reliability and stability. During the implementation process, it is necessary to closely monitor the structural safety of the bridge to prevent the bridge span structure from being damaged due to tilt. Therefore, the stability and reliability of the entire jacking system are crucial to ensuring the stability of the bridge. In the bridge jacking system, steel brackets are high-strength, easy-to-operate, and cost-effective auxiliary equipment. When there is not enough space in the original structure of the bridge to arrange the jacking equipment, they can serve as support points or force points during the jacking process to help safely lift the bridge structure to the predetermined height.
[0004] During the jacking process, ordinary steel corbels may tilt or twist due to uneven force due to the large jacking force, causing the entire jacking system to become unstable and lead to accidents. Utility Model Content

[0025] The utility model is further described below in conjunction with the accompanying drawings.
[0026] like Figures 1 to 6 The utility model provides an embodiment: a steel corbel monitoring mechanism for bridge jacking, wherein a warning host 2 is fixed on the steel corbel 1, and the warning host 2 is triggered by a balance monitoring component 3. The balance monitoring component 3 can monitor the steel corbel 1 during its jacking process. When tilt occurs, the warning host 2 is triggered, and the warning host 2 can emit an alarm sound and a warning light 23, which can serve as a warning to the staff; the balance monitoring component 3 includes an insulating shell 31, and the inner walls of the insulating shell 31 are provided with a conductive metal layer 32, and the inner bottom of the insulating shell 31 is fixed with a conductive metal layer with a middle low and an outer high The conductive metal disc 33 is a metal disc 33. The conductive metal layer 32 and the conductive metal disc 33 can be made of copper, but not limited thereto. The conductive metal disc 33 has a small copper ball 34. When the steel corbel 1 is in a stable state, the small copper ball 34 is located at the central low point of the conductive metal disc 33. When the steel corbel 1 is tilted, the small copper ball 34 can slide to the gap between the conductive metal layer 32 and the conductive metal disc 33. Since the small copper ball 34 is conductive, the conductive metal layer 32 and the conductive metal disc 33 can be connected, so that the warning host 2 can be powered on, and an alarm sound and a warning light 23 can be emitted. The ball diameter of the small copper ball 34 is larger than the gap between the conductive metal layer 32 and the conductive metal disc 33, so that it can be stuck in the gap; the bottom of the insulating shell 31 is connected to the warning host 2 via the data line 4.
[0027] The warning host 2 includes a shell 21; a speaker 22 is provided at the left end of the front side of the shell 21 for emitting an alarm sound, and a warning light 23 is provided at the right end; a first connection socket is provided on the top middle side of the shell 21, and a battery compartment 24 is provided on the right side, and a battery is provided in the battery compartment 24, which can provide power; a second connection socket 35 is provided at the bottom of the insulating shell 31, and the second connection socket 35 is connected to the first connection socket via a data cable 4, and the data cable 4 can be a USB data cable 4, but is not limited to this.

There is a gap between the conductive metal disc 33 and the conductive metal layer 32 to form an open circuit.

[0029] In one embodiment of the utility model, the top of the insulating shell 31 is fixed to the top flat plate 101 of the steel corbel 1 via a magnetic plate 5, and the magnetic plate 5 is fixed to the insulating shell 31, so that the insulating shell 31 can be adsorbed on the top flat plate 101 of the steel corbel 1 through the magnetic plate 5, so that the insulating shell 31 can be easily installed on the steel corbel 1 or removed from the steel corbel 1.
[0030] In one embodiment of the utility model, two slide grooves 61 are provided on the upper end surface of the top plate 101 of the steel corbel 1, and a latch 63 is connected to the slide groove 61 via a spring 62. A grab plate 64 is fixed to the top of the latch 63, which can be easily grabbed by the staff; an insertion block 65 is fixed to the top of the insulating shell 31, and the upper end of the insertion block 65 penetrates the top plate 101 and extends into the slide groove 61.

[0031] Pull the two latches 63, the spring 62 is compressed, and then the two plugs 65 are inserted into the corresponding slide grooves 61, and then the latches 63 are released. Due to the reset effect of the spring 62, the latches 63 pop out through the sockets, thereby fixing the insulating housing 31 on the steel bracket 1.
[0032] In one embodiment of the utility model, a limiting groove 66 is provided on the inner wall of the slide groove 61 away from the spring 62 , and a limiting block 67 for inserting the limiting groove 66 is fixed on the latch 63 , so as to better fix the insulating shell 31 .

[0036] In one embodiment of the utility model, the inclination angle of the conductive metal disc 33 is 4.9°. The steel bull leg 1 serves as a lifting chassis when the jack is lifted or lowered. According to the vertical requirement of the jack, the axis should be vertical, and its deviation should be less than 5°. Therefore, the inclination angle of the conductive metal disc 33 is 4.9°. When the steel bull leg 1 becomes unstable and the inclination angle reaches 5°, the climbing surface on one side of the conductive metal disc 33 becomes a downslope surface, and the small copper ball 34 slides down into the gap between the conductive metal disc 33 and the conductive metal layer 32 under the action of gravity.
