A laser receiver 7 is provided on the upper surface of the second monitoring ring 6, and a laser transmitter 8 is provided on the lower surface of the first monitoring ring 2. Through the cooperation between the laser receiver 7 and the laser transmitter 8, the monitoring device can not only monitor the deformation of the umbrella-shaped steel structure body 1 through the movement of the telescopic rod 204, but also issue a reminder in time when it twists, which can effectively reduce the danger caused by structural deformation.

[0032] The two stabilizing plates 304 are parallel to each other, and the laser receiver 7 should issue an alarm after not receiving a laser signal for a period of time to reduce the probability of false alarms.

[0033] Working principle: A device for monitoring the torsional deformation of an umbrella-shaped steel structure. When in use, the assembly ring 201 with the preliminary fixing component is first inserted into the gap of the umbrella-shaped steel structure body 1 with the help of the protrusion 202, and then the threaded rod 301 is driven to rotate by the knob 3. Since the motion block 302 is restricted by the upper and lower inner walls of the protrusion 202 and cannot rotate, the motion block 302 is synchronously driven to move horizontally when the threaded rod 301 rotates. The motion block 302 is set to be trapezoidal, so when the motion block 302 moves, it will synchronously squeeze the two stabilizing plates 304. After being squeezed, the two stabilizing plates 304 bulge outward. The outer side of 202 moves, and the protrusion 202 moves, which will synchronously drive the limiting cylinder 307 to move. When the limiting cylinder 307 moves, the first spring 308 is stretched and the limiting rod 306 is used to limit its own movement trajectory. After the stabilizing plate 304 moves, it contacts the steel structure body 1, thereby preliminarily fixing the assembly ring 201, and the friction between the stabilizing plate 304 and the steel structure body 1 can be increased with the help of the rubber protrusion 305. At this time, the protrusion 202 is fixed to the steel structure body 1 with the help of a welding tool, and then the remaining assembly rings 201 are pushed upward from the bottom side, and the upper surface of the assembly ring 201 is used to contact the triangular block. 402 contacts and forces the triangular block 402 to retract into the interior of the telescopic slot 4. When the triangular block 402 is retracted, the second spring 401 is compressed. When the slot 403 is aligned with the triangular block 402, the triangular block 402 is pushed into the interior of the slot 403 under the action of the second spring 401. After being spliced ​​into a ring with the help of four assembly rings 201, it is further fixed again with the help of welding tools. Then, by rotating the telescopic rod 204, the threaded groove 206 cooperates with the adjustment sleeve 203 to make the telescopic rod 204 move upward. After the telescopic rod 204 moves, it drives the ball head 205 to contact the lower side of the umbrella-shaped structure of the steel structure body 1. When the umbrella-shaped structure is deformed, the telescopic rod 204 will be squeezed to move downward. When the telescopic rod 204 moves, the synchronization plate 503 will be driven to descend synchronously. After the synchronization plate 503 descends, the trigger button 504 is pressed, and then a signal transmitter connected to the trigger button 504 is used to send a signal, thereby completing the monitoring of the deformation of the umbrella-shaped steel structure. At the same time, under normal conditions, the laser transmitter 8 emits a laser which is received by the laser receiver 7. When the steel structure body 1 is twisted, the first monitoring ring 2 and the second monitoring ring 6 are misaligned, so that the laser receiver 7 cannot receive the laser signal, and then the twisting of the steel structure is detected.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
