DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] In order to further understand the content of the present invention, the present invention is described in detail in conjunction with the accompanying drawings.

[0033] Combination Figure 1 - Fig. 9 A smart scaffolding equipped with an embedded video monitoring system includes a hollow column 1 and a tripod crossbeam 2, the hollow column 1 and the tripod crossbeam 2 are connected by a quick connector 3, the hollow column 1 is a whole continuous column running through the upper and lower ends of the scaffolding, the cross section of the hollow column 1 is a double-layer concentric circle structure with a notch, and a limit groove 101 running through the upper and lower ends is opened at the notch of the hollow column 1, an embedded monitor 4 is arranged in the hollow column 1, a monitoring camera 5 is arranged in the embedded monitor 4, the monitoring camera 5 is equipped with a wide-angle lens 501, and the wide-angle lens 501 of the monitoring camera 5 is located in the limit groove 101, so that the embedded monitor 4 moves up and down in the hollow column 1, and the wide-angle lens 501 will move up and down along the limit groove 101, and the limit grooves 101 of the hollow column 1 are all facing the inside of the scaffolding, so that video monitoring is performed through the wide-angle lens 501, and the monitoring range is wide.

[0034] The quick connector 3 includes a first connector 301 and a second connector 302, which are movably connected via a hinge. A first beam interface 303 is provided on the first connector 301, and a second beam interface 304 is provided on the second connector 302. The first beam interface 303 and the second beam interface 304 are fixedly connected to the tripod beam 2 via threads, and a column clamping groove 305 is provided between the first connector 301 and the second connector 302. In this way, when installing the tripod beam 2, the tripod beam 2 is installed in place, and the first connector 301 and the second connector 302 can be driven by the lever force to rotate around the hinge to clamp the hollow column 1. Through interference fit, quick fastening is achieved without the need for additional bolts, which is efficient and convenient. At the same time, the special structure of the quick connector 3 will not affect the movement and shooting of the wide-angle lens 501, and it also facilitates the up and down movement of the safety belt.

[0035] A counterweight block 6 is fixedly connected below the monitoring camera 5, and a seat belt buckle 7 for connecting a seat belt is fixedly connected below the counterweight block 6. A lifting drive module 8 is fixedly connected above the monitoring camera 5. The lifting drive module 8 is used to drive the embedded monitor 4 to rise and fall along the hollow column 1. A driving motor 801 is arranged in the lifting drive module 8. A worm 802 is fixedly connected to the output shaft of the driving motor 801. The worm 802 is meshed with a worm wheel 803. A rubber wheel 804 is fixedly connected to one side of the worm wheel 803. The rubber wheel 804 contacts the inner wall of the hollow column 1. Two groups of worm wheels 803 and rubber wheels 804 are arranged, and the two groups of worm wheels 803 and rubber wheels 804 are distributed symmetrically around the worm 802, pressing the inner wall of the hollow column 1 tightly, so that the driving motor 801 can drive the two driving motors 801 to rotate through the worm wheel 803 and worm 802, thereby driving the embedded monitor 4 to rise and fall. At the same time, a hollow groove 102 is provided between the double outer walls of the hollow column 1, and a tile-shaped counterweight 10 is provided in the hollow groove 102. A steel wire rope 11 is fixedly connected to the top of the center rod 901, and a fixed pulley 12 is provided at the top of the hollow column 1. The steel wire rope 11 passes around the fixed pulley 12 at the top of the hollow column 1 and is fixedly connected to the tile-shaped counterweight 10. The tile-shaped counterweight 10 is of the same weight as the embedded monitor 4, so that the rubber wheel 804 only needs a very small torque to drive the embedded monitor 4 to move.

[0036] A fall protection module 9 is fixedly connected above the lifting drive module 8, and a center rod 901 is arranged in the fall protection module 9. The lower end of the center rod 901 is rotatably connected to a first connecting rod 903 through a first connecting shaft 902, and the other end of the first connecting rod 903 is rotatably connected to a second connecting rod 905 through a second connecting shaft 904. The second connecting rod 905 is fixedly connected to an eccentric deceleration block 906, and the eccentric deceleration block 906 is rotatably connected to the outer shell of the fall protection module 9 through an eccentric shaft 907. A spring baffle 908 is fixedly connected to the center rod 901 through a thread, and a pressure spring 909 is arranged above the spring baffle 908. The pressure spring 909 is used to Push the center rod 901 downward, so that under normal conditions, the pressure spring 909 pushes the center rod 901 downward, and at the same time, the center rod 901 drives the eccentric reduction block 906 to rotate inward around the eccentric shaft 907 through the connecting rod, so that the eccentric reduction block 906 does not contact the inner wall of the hollow column 1, so that the embedded monitor 4 can be freely raised and lowered. When the worker falls, the embedded monitor 4 is instantly pulled downward, and at the same time, the tile-shaped counterweight block 10 applies tension to the embedded monitor 4 through the wire rope 11 due to inertia, thereby starting the fall protection module 9, so that the embedded monitor 4 is locked with the hollow column 1 to stop the worker from continuing to fall.

[0037] Specifically, a tension pressure sensor 701 is provided at the connection between the safety belt buckle 7 and the counterweight block 6, so that it is possible to detect whether the worker's safety belt is buckled on the safety belt buckle 7 through changes in tension and pressure. At the same time, when the worker accidentally falls, the safety belt is tightened, and the tension pressure sensor 701 can also detect the instantaneous increase in tension, thereby issuing an alarm to provide timely help.

[0038] Specifically, the eccentric deceleration block 906 is made of hard rubber, and an anti-slip groove is processed on the outer arc surface of the eccentric deceleration block 906. The eccentric shaft 907 of the eccentric deceleration block 906 deviates from its center of the circle, so that when the eccentric deceleration block 906 contacts the inner wall of the hollow column 1, the friction force will further drive the eccentric deceleration block 906 to rotate, and the tighter the eccentric deceleration block 906 is stuck to the hollow column 1, the less likely the worker will continue to fall. When unlocking is needed, the embedded monitor 4 can be easily unlocked by moving it upwards.

[0039] Working principle: When a smart scaffold equipped with an embedded video monitoring system is working, the embedded monitor 4 can move up and down with the workers for video monitoring. The workers can also use a safety belt to connect to the safety belt buckle 7 on the embedded monitor 4 to ensure safety. A tension pressure sensor 701 is provided at the connection between the safety belt buckle 7 and the counterweight 6, so that it can detect whether the worker's safety belt is buckled on the safety belt buckle 7 through the changes in tension and pressure. At the same time, when the worker accidentally slips and falls, the safety belt is tightened, and the tension pressure sensor 701 can also detect the instantaneous increase in tension, thereby issuing an alarm to provide timely help.

[0040] When a worker falls from a height, the embedded monitor 4 is instantly pulled downward. At the same time, due to inertia, the tile-shaped counterweight 10 applies tension to the center rod 901 through the wire rope 11, thereby compressing the pressure spring 909 and driving the eccentric deceleration block 906 to rotate through the connecting rod, so that the eccentric deceleration block 906 contacts the hollow column 1, and further utilizes the friction between the eccentric deceleration block 906 and the inner wall of the hollow column 1 to make the eccentric deceleration block 906 further rotate, making it stick tighter, so that the embedded monitor 4 is locked with the hollow column 1 to stop the worker from falling further.

[0041] 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.
