[0037] Construction safety is a safety issue encountered in the engineering construction of various industries. Construction safety issues directly affect the lives and property safety of construction workers.
[0038] During the engineering construction of building types and environments, it is often necessary to perform high-altitude operations or work in relatively deep foundation pits. Construction workers are at a relatively high position on the plane and generally use ropes to connect their bodies to the frame or building components. When a fall occurs, the construction workers will quickly fall in a free-fall manner. When the ropes are fully straightened, the construction workers will suddenly stop falling. At this time, the ropes are likely to cause serious injuries to the construction workers.
[0039] To solve the above problems, the embodiments of the present application provide a construction safety insurance device. The following will describe the solution provided by the embodiments of the present application in detail with reference to the accompanying drawings of the specification.
[0040] Figure 1 is a schematic structural diagram of a construction safety insurance device provided by an embodiment of the present application; Figure 2 is a cross-sectional view of a construction safety insurance device provided by an embodiment of the present application; Figure 3 is an electrical diagram of a construction safety insurance device provided by an embodiment of the present application.
[0041] Refer to Figures 1 to 3As shown in the figure, an embodiment of the present application provides a construction safety insurance device, which includes a mounting base 100, a fall prevention rope 200, a rope winding assembly 300, a deceleration assembly 400, a detection assembly 500, a controller 600, and a battery 700. Among them, the rope winding assembly 300 is fixedly connected to the mounting base 100; the fall prevention rope 200 is wound around the rope winding assembly 300; the free end of the fall prevention rope 200 is connected to the safety belt 1000 of the construction worker.
[0042] The deceleration assembly 400 is connected to the mounting base 100, and the deceleration assembly 400 is arranged on one side of the rope winding assembly 300; the detection assembly 500 is connected to the mounting base 100, and the detection assembly 500 is used to detect the falling speed of the fall prevention rope 200; the detection assembly 500, the controller 600, and the deceleration assembly 400 are all electrically connected to the battery 700 through wires; the battery 700 is used to supply power to the detection assembly 500, the controller 600, and the deceleration assembly 400.
[0043] The controller 600 is arranged on the mounting base 100. The detection assembly 500 is electrically connected to the controller 600 through a wire, and the controller 600 is electrically connected to the deceleration assembly 400 through a wire. The controller 600 selectively controls the deceleration assembly 400 to apply a force to the rope winding assembly 300 to reduce the falling speed of the fall prevention rope 200. Specifically, the controller 600 determines whether to act according to the falling speed of the fall prevention rope 200 measured by the detection assembly 500. When the falling speed of the fall prevention rope 200 is greater than a certain set value, the controller 600 controls the deceleration assembly 400 to gradually apply a force to the rope winding assembly 300 to gradually reduce the falling speed of the fall prevention rope 200, so as to avoid serious injuries caused to construction workers by the sudden stop of the falling rope.
[0044] In some examples, along the length direction of the fall prevention rope 200, a plurality of metal sheets are evenly spaced in the fall prevention rope 200; the detection assembly 500 is configured as a Hall proximity switch, and the controller 600 calculates the falling speed of the fall prevention rope 200 according to the time difference between detecting adjacent metal sheets by the Hall proximity switch. Specifically, the controller 600 can calculate the falling speed of the fall prevention rope 200 according to the distance between adjacent metal sheets and the time difference, and then compare it with a preset speed value.
[0045] Figure 4 is Figure 1 the assembly drawing of the wire winding assembly and the deceleration assembly 400 in.
[0046] Refer to Figure 4As shown, exemplary, the rope winding assembly 300 includes a rope winding shaft 310 and a speed reduction disk 320. The rope winding shaft 310 and the speed reduction disk 320 are coaxially arranged. The rope winding shaft 310 is cooperatively arranged on the mounting base 100. The anti-falling rope 200 is wound around the rope winding shaft 310. During the falling process of the anti-falling rope 200, the rope winding shaft 310 is driven to rotate. The speed reduction assembly 400 is arranged on one side of the speed reduction disk 320, and the speed reduction assembly 400 selectively applies a force to the speed reduction disk 320. It can be understood that when the speed reduction assembly 400 applies a force (frictional force) to the speed reduction disk 320, the rotation speed of the speed reduction disk 320 decreases, thereby reducing the speed of the rope winding shaft 310, and finally reducing the falling speed of the anti-falling rope 200. That is to say, the speed reduction assembly 400 controls the falling speed of the anti-falling rope 200 through the speed reduction disk 320 and the rope winding shaft 310.
[0047] Continue to refer to Figure 4 As shown, the speed reduction assembly 400 includes a speed reduction member 410, a limiting rod 420, and a driving motor 430. Among them, the speed reduction member 410 is arranged on one side of the speed reduction disk 320, and the speed reduction member 410 is slidably arranged on the limiting rod 420. The driving motor 430 is connected to the speed reduction member 410. The driving motor 430 drives the speed reduction member 410 to slide along the limiting rod 420, and the driving motor 430 selectively makes the speed reduction member 410 contact the speed reduction disk 320 to apply a force to the speed reduction disk 320.
[0048] Exemplary, the speed reduction assembly 400 further includes a driving screw 440, a first transmission gear 450, and a second transmission gear 460. The driving screw 440 is cooperatively connected to the speed reduction member 410. The driving screw 440 is fixedly connected to the first transmission gear 450. The second transmission gear 460 is meshed with the first transmission gear 450. The second transmission gear 460 is fixedly connected to the driving motor 430. The driving motor 430 drives the driving screw 440 to rotate through the first transmission gear 450 and the second transmission gear 460. During the rotation process of the driving screw 440, the speed reduction member 410 is driven to move along the limiting rod 420, and the speed reduction member 410 approaches or moves away from the speed reduction disk 320. After the speed reduction member 410 contacts the speed reduction disk 320, the rotation speed of the speed reduction disk 320 gradually decreases under the action of the frictional force.
[0049] In some examples, the construction safety insurance device further includes a protective shell 800. The protective shell 800 is fixedly arranged on the mounting base 100. Both ends of the limiting rod 420 are fixedly installed on the side wall of the protective shell 800.
[0050] Continue to refer to Figure 4As shown, in order to improve the deceleration effect of the deceleration disc 320, in some examples, there are two deceleration members 410, and the two deceleration members 410 are respectively connected to the two ends of the driving screw 440. Additionally, exemplarily, a rubber member is provided on the side of the deceleration member 410 facing the deceleration disc 320, thereby increasing the frictional force between the deceleration member 410 and the deceleration disc 320.
[0051] Figure 5 is Figure 1 The installation schematic diagram of the detection component 500 in
[0052] Referring to Figure 2 and Figure 5 As shown, in some examples, the construction safety insurance device further includes a limiting member 900. The limiting member 900 is connected to the mounting base 100. The limiting member 900 has a through hole for the anti-falling rope 200 to pass through, and the anti-falling rope 200 is threaded through the through hole. The detection component 500 is fixedly arranged on one side of the limiting member 900 and its detection end faces the through hole. The limiting member 900 can limit the moving position of the anti-falling rope 200 to ensure that the detection component 500 can detect the falling speed of the anti-falling rope 200.
[0053] Figure 6 is Figure 1 The schematic diagram of the deceleration disc 320 in
[0054] Referring to Figure 6 As shown, exemplarily, the deceleration disc 320 is disc-shaped, and deceleration bumps can be provided on its side to facilitate deceleration.
[0055] It is easy to understand that those skilled in the art can combine, split, reorganize, etc. the embodiments of the present application based on several embodiments provided by the present application to obtain other embodiments, and these embodiments do not exceed the protection scope of the present application.
[0056] The above specific embodiments further elaborate on the purpose, technical solutions, and beneficial effects of the embodiments of the present application. It should be understood that the above are only the specific embodiments of the embodiments of the present application and are not used to limit the protection scope of the embodiments of the present application.
