Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] See also Figure 1-Figure 6 , the utility model provides a technical solution:

[0035] Embodiment 1:

[0036] A tower crane safety monitoring device comprises a device body 1, a display screen 2 and a control button 3, wherein the display screen 2 is fixedly embedded in one side of the device body 1, the control button 3 is fixedly installed on one side of the device body 1, a transmission box 4 is fixedly connected to the top of the device body 1, a support block 5 is arranged on the front side of the transmission box 4, a cleaning cotton block 6 for cleaning the display screen 2 is fixedly connected to one side of the support block 5, and a transmission mechanism is arranged inside the transmission box 4 to control the cleaning cotton block 6 to reciprocate;

[0037] The extrusion mechanism is fixedly arranged on the transmission mechanism. When the transmission mechanism controls the cleaning cotton block 6 to move back and forth, the extrusion mechanism sprays alcohol onto the cleaning cotton block 6;

[0038] One implementation of the present embodiment 1 is as follows: the transmission mechanism includes a twisting block 7 arranged on one side of the transmission box 4, two twisting grooves 8 are provided on the surface of the twisting block 7, a threaded rod 9 is fixedly connected to one side of the twisting block 7, one end of the threaded rod 9 penetrates into the interior of the transmission box 4, a transmission block 10 is transmission-connected to the surface of the threaded rod 9, a threaded hole 11 for use with the threaded rod 9 is provided on one side of the transmission block 10, a moving block 12 is fixedly connected to one side of the transmission block 10, one side of the moving block 12 extends to the outside of the transmission box 4, and the bottom of the moving block 12 is fixedly connected to the top of the support block 5.

[0039] In this embodiment, it is considered that during the use of the monitoring video screen, since it is in a construction site environment, dust is easily adhered to its surface. If it is not cleaned in time, it will affect the operator's viewing of the monitoring video screen to understand the application of the tower crane, thereby causing inconvenience. Therefore, by setting a transmission mechanism, when there is dust on the display screen 2, by rotating the twisting block 7, the twisting block 7 drives the threaded rod 9 to rotate around the bearing seat 27. During the rotation of the threaded rod 9, the external thread on its surface will squeeze the internal thread of the threaded hole 11, thereby transmitting the transmission block 10. The transmission block 10 drives the moving block 12, the supporting block 5 and the cleaning cotton block 6 to move. When the cleaning cotton block 6 passes the display screen 2, it will wipe off the dust on the display screen 2, thereby achieving the effect of cleaning the display screen 2;

[0040] The problem that the monitoring screen is in a construction site environment and dust easily adheres to its surface during use is solved. If it is not cleaned in time, it will affect the operator's viewing of the monitoring screen to understand the application of the tower crane, thus causing inconvenience.

[0041] It should be noted that, by rotating the twisting block 7 in the reverse direction, the cleaning cotton block 6 and other structures will move in the reverse direction.

[0042] Preferably, a bearing seat 27 is provided at one end of the threaded rod 9 , and the threaded rod 9 is rotatably connected to the inner wall of the transmission box 4 through the bearing seat 27 .

[0043] In this embodiment, the bearing seat 27 is provided to support the threaded rod 9 and improve the smoothness of the threaded rod 9 during rotation.

[0044] Embodiment 2:

[0045] On the basis of the first embodiment, the transmission mechanism in this embodiment can control the movement of the cleaning cotton block 6 to wipe the dust on the surface of the display screen 2. However, considering that some stubborn dust is difficult to remove by simple wiping, the extrusion mechanism in this application includes a tank body 13 fixedly arranged on the top of the moving block 12 for storing alcohol, and the bottom of the tank body 13 is fixedly connected to a transmission pipe 14, and a first one-way valve 15 is fixedly installed on the surface of the transmission pipe 14;

[0046] One side of the tank body 13 is fixedly connected to an air collecting box 16, and an air intake pipe 17 is arranged on the top of the air collecting box 16. A second one-way valve 18 is fixedly installed on the surface of the air intake pipe 17. A push block 19 is arranged inside the air collecting box 16, and a push rod 20 is fixedly connected to one side of the push block 19. One end of the push rod 20 passes through the outside of the air collecting box 16 and is fixedly connected to an extrusion block 21. One side of the transmission box 4 is fixedly connected to a plurality of protrusions 22. A tension spring 23 is sleeved on the surface of the push rod 20, and one end of the tension spring 23 is fixedly connected to one side of the push block 19, and the other end of the tension spring 23 is fixedly connected to the inner wall of the air collecting box 16.

[0047] In this embodiment, it is considered that some stubborn dust is difficult to remove by simple wiping. Therefore, by setting an extrusion mechanism, when the moving block 12 moves, part of the extrusion mechanism structure will move. When the hypotenuse of the extrusion block 21 contacts the protrusion 22, the extrusion block 21 will drive the push rod 20, the push block 19 and the piston 24 to move in the air collecting box 16 under the influence of extrusion, and the gas in the air collecting box 16 will be compressed. Under the influence of air pressure, the first one-way valve 15 will open, and at the same time, the alcohol in the tank body 13 will be discharged from the transmission pipe 14 and sprayed on the cleaning cotton block 6. When the extrusion block 21 does not contact the protrusion 22, the tension generated by the tension spring 23 will drive the push block 19 and the piston 24 to reset. At this time, the air collecting box 16 is under negative pressure, and the gas will enter the air collecting box 16 through the air inlet pipe 17, and spray alcohol on the cleaning cotton block 6 in a cycle, thereby improving the wiping effect of the cleaning cotton block 6.

[0048] Solved the problem that some stubborn dust is difficult to remove by simple wiping;

[0049] It should be noted that alcohol needs to be added into the tank body 13 in advance, and the first one-way valve 15 is a valve that can only discharge air to the outside of the transmission pipe 14, and the second one-way valve 18 is a valve that can only take air into the air collecting box 16.

[0050] Preferably, a piston 24 is fixedly connected to one side of the push block 19, and the piston 24 is made of rubber.

[0051] In this embodiment, by providing the piston 24, the sealing performance inside the air collecting box 16 can be improved so that a sealed air chamber is formed inside the air collecting box 16 to facilitate the squeezing of air.

[0052] Preferably, a liquid inlet pipe 25 is fixedly connected to the top of the tank body 13 , and a sealing cover 26 is threadedly connected to the surface of the liquid inlet pipe 25 .

[0053] In this embodiment, by providing the liquid inlet pipe 25 and the sealing cover 26 , after the alcohol in the tank body 13 is used up, the sealing cover 26 can be twisted to open it, so that the alcohol in the tank body 13 can be replenished.

[0054] Preferably, both sides of the extrusion block 21 are sloped.

[0055] In this embodiment, by setting a slope shape on both sides of the extrusion block 21, when the oblique edge part of the extrusion block 21 contacts the protrusion 22, under the influence of extrusion, the extrusion block 21 will drive the push rod 20, the push block 19 and the piston 24 to move in the air collecting box 16, thereby playing a transmission role.

[0056] Working principle: When there is dust on the display screen 2, the twisting block 7 is rotated, and the twisting block 7 drives the threaded rod 9 to rotate around the bearing seat 27. During the rotation of the threaded rod 9, the external thread on its surface squeezes the internal thread of the threaded hole 11, thereby transmitting the transmission block 10. The transmission block 10 drives the moving block 12, the supporting block 5 and the cleaning cotton block 6 to move. When the cleaning cotton block 6 passes the display screen 2, it will wipe off the dust on the display screen 2, thereby achieving the effect of cleaning the display screen 2;

[0057] When the moving block 12 moves, it will also move part of the extrusion mechanism structure. When the hypotenuse of the extrusion block 21 contacts the protrusion 22, the extrusion block 21 will drive the push rod 20, the push block 19 and the piston 24 to move in the air collecting box 16 due to the extrusion, and compress the gas in the air collecting box 16. Under the influence of air pressure, the first one-way valve 15 will open, and at the same time, the alcohol in the tank body 13 will be discharged from the transmission pipe 14 and sprayed on the cleaning cotton block 6. When the extrusion block 21 is not in contact with the protrusion 22, the tension generated by the tension spring 23 will drive the push block 19 and the piston 24 to reset. At this time, the air collecting box 16 is under negative pressure, and the gas will enter the air collecting box 16 through the air inlet pipe 17, and spray alcohol on the cleaning cotton block 6 in a cycle, thereby improving the wiping effect of the cleaning cotton block 6.

[0058] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
