When the tower crane tilts and vibrates or vibrates during construction, the wall of the upper groove 21 of the rubber seat 17 of the protective structure 5 buffers and reduces shock to the box body 6 of the monitoring and alarm device. The damper 20 (the damper 20 can specifically adopt the buffer HCL-26 or buffer HCL-34 of Heying) arranged between the bottom of the rubber seat 17 and the bottom wall of the shell 18 further consumes vibration energy, improves stability, and reduces vibration damage.

[0045] Based on the above implementation form, Figure 4 As shown, a plurality of first springs 22 are evenly arranged on the outer periphery of the damper 20, one end of the plurality of first springs 22 is connected to the bottom of the rubber seat 17, and the other end is connected to the bottom wall of the shell 18, so as to improve the buffering and shock absorbing effect.

[0046] On the basis of the above implementation, the size of the upper groove 21 matches the size of the lower portion of the box body 6 , so that the lower portion of the box body 6 is in close contact with the inner wall of the upper groove 21 .

[0047] Based on the above implementation form, Figure 5 As shown, the upper groove 21 is a groove body that is larger at the top and smaller at the bottom, which is convenient for the box body 6 to be disassembled and assembled on the rubber seat 17. The size of the inner bottom wall of the upper groove 21 matches the size of the bottom of the box body 6, and the bottom of the box body 6 abuts against the upper groove 21. The box body 6 is connected to the protective structure 5 through a connecting structure.

[0048] Based on the above implementation, the connection structure includes:

[0049] The thread grooves 23 are arranged on the left and right side walls and the rear wall of the lower part of the box body 6;

[0050] A plurality of first threaded holes 24 are provided on the wall of the upper groove 21, each of the first threaded holes 24 corresponds to the threaded groove 23 and is coaxially arranged;

[0051] A plurality of second threaded holes 25 are provided on the housing 18, each of the second threaded holes 25 corresponds to the first threaded hole 24 and is coaxially arranged;

[0052] A plurality of bolts 30 are provided with a second spring 28, and the screw rod 27 of each bolt 30 is threadedly connected with the second threaded hole 25, the first threaded hole 24 and the thread groove 23; when in use, the screw rod 27 of the bolt 30 is threadedly connected with the second threaded hole 25, the first threaded hole 24 and the thread groove 23 at the same time, and one end of the second spring 28 abuts against the inner side of the head 29 of the bolt 30, and the other end abuts against the outer side of the second threaded hole 25, and the second spring 28 is in a pre-compression state to improve the shock absorption and stabilization effect of the monitoring alarm device installed on the rubber seat 17.

[0053] In the specific configuration, a thread groove 23 can be provided on each of the left and right side walls and the rear wall of the lower part of the box body 6, three first threaded holes 24 are provided, and three second threaded holes 25 are provided, and the thread specifications are the same, so that the screw rod 27 of the same bolt 30 can be threadedly connected with the second threaded hole 25, the first threaded hole 24 and the thread groove 23 at the same time. As the screw rod 27 is screwed in, the second spring 28 is continuously squeezed and compressed, and when it is in a pre-compression state, it can stop being screwed in. The head 29 of the bolt 30 adopts a hexagonal head for easy operation.

[0054] On the basis of the above implementation, a limiting groove 26 is provided outside the second threaded hole 25 for accommodating the second spring 28 in a pre-compressed state.

[0055] The monitoring and alarm device 16 for tower crane construction is installed at a position such as Figure 6 As shown, the monitoring alarm device 16 is installed on the side wall of the tower crane body 3 through the support frame 4, and is used to monitor the inclination of the tower crane and the safety of the construction workers around the hook 14. It includes the above-mentioned protective structure 5, and includes:

[0056] A box 6 is used to install the mainboard of the monitoring alarm device in the box 6, and the display screen 7, warning light 8, and voice player 9 of the monitoring alarm device are installed on the upper part of the box 6. The display screen 7, warning light 8 and voice player 9 are used to convey warning information; the bottom or lower part of the box 6 is installed in the upper groove 21 of the protective structure 5;

[0057] The displacement sensor includes a laser emitting module 11 and a laser receiving module 2. The laser emitting module 11 is installed below the crane arm near the tower crane body 3, corresponding to the laser receiving module 2 surrounding the foundation 1, and is used to monitor the tilt of the tower crane. The vertical connection line of the two modules is parallel to the tower crane body 3. When the tower crane body 3 tilts beyond the safe range, the laser emitted by the laser emitting module 11 to the laser receiving module 2 is offset, resulting in different laser signals received by the laser receiving module 2, generating different signals and transmitting them to the main board, which determines and controls the display screen 7, the warning light 8 and the voice player 9 to convey the early warning information.

[0058] A human body sensor 15 is installed on the hook 14 to sense construction personnel around the hook 14. The hook 14 is suspended on the crane arm by a steel rope 13, and a camera 12 is installed above it;

[0059] The laser emitting module 11, the laser receiving module 2, the human body sensor 15, the camera 12, the display screen 7, the warning light 8 and the voice player 9 are all electrically connected to the mainboard.

[0060] The specific working process of the monitoring and alarm device for tower crane construction is as follows:

[0061] When the tower crane body 3 tilts beyond the safe range, the laser emitted by the laser emitting module 11 to the laser receiving module 2 is offset, resulting in different laser signals received by the laser receiving module 2 (for example, the laser receiving module 2 receives a vertical laser signal when in a non-tilted state, receives a tilted laser signal when slightly tilted, and does not receive a laser signal when tilted beyond the safe range). The mainboard identifies and judges the signal transmitted by the laser receiving module 2, and then controls the display screen 7 to display the danger information of the tilt of the tower crane body 3, the warning light 8 emits a flashing warning light 8, and the voice player 9 plays the voice information of the tilt of the tower crane body 3;

[0062] When the human body sensor 15 at the hook 14 senses that there is someone around the hook 14, the human body sensor 15 will transmit the sensed information to the main board, and then release the alarm information in the form of flashing red light of the warning light 8 or playing a warning by the voice player 9 through the main board; at the same time, the camera 12 on the tower crane boom 10 will also transmit the picture near the hook 14 to the main board, and issue an alarm after analysis to prevent the human body sensor from failing to remind the construction personnel in time due to insufficient sensing range.

[0063] In summary, the utility model is not only beneficial to the shock absorption protection of the monitoring alarm device, but also convenient for outdoor construction workers to receive alarms in time, thereby improving the safety of construction.

[0064] Although the embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the specification and the embodiments. They can be fully applied to various fields suitable for the present invention. For those familiar with the art, additional modifications can be easily realized.
