Detailed Implementation

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and do not limit the present utility model.

[0016] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0017] Please see Figure 1 This utility model provides a construction safety fall arrest net, which includes:

[0018] The system comprises a support plate 1 and multiple movable wheels 2 mounted on the support plate 1. There are two support plates 1. A distance adjustment mechanism 3 is fixed between the two support plates 1 to adjust the distance between them. A disassembly / assembly mechanism 4 is fixedly installed on the side of the two support plates 1 that are close to each other. The disassembly / assembly mechanism 4 has hanging rings 5, which can be installed and removed via the mechanism. Safety nets 6 are fixedly installed on the hanging rings 5 ​​on both sides. A stabilizing mechanism 7 is fixedly installed on the lower side of the support plate 1 and can extend downwards to suspend the movable wheels 2, thus maintaining the stability of the fall protection net.

[0019] When using this construction safety fall protection net, firstly, the fall protection net can be moved to the designated position by the rolling of the movable wheel 2. Then, rotate the control end of the stabilizing mechanism 7, and the stabilizing mechanism 7 will extend downward and suspend the movable wheel 2. With the support of the stabilizing mechanism 7, the fall protection net can remain stable. When construction workers fall, the cushioning effect of the two safety nets 6 can effectively protect the safety of the construction workers. The safety net 6 will gradually age during long-term use. The hanging ring 5 and the safety net 6 can be removed by the disassembly and assembly mechanism 4. Rotate the control end of the distance adjustment mechanism 3, and the distance adjustment mechanism 3 will drive the two support plates 1 to approach each other. Then, the new safety net 6 is placed on the disassembly and assembly mechanism 4 through the hanging ring 5 for fixation. Rotate the control end of the distance adjustment mechanism 3 in the opposite direction to control the two support plates 1 to move away from each other until the safety net 6 is tightened.

[0020] like Figure 2As shown, in a preferred embodiment of this utility model, the distance adjustment mechanism 3 includes: a sleeve plate 31, which is disposed between two support plates 1, and a handle 32 is rotatably mounted on the sleeve plate 31. A first bevel gear 33 is fixed to one end of the handle 32 inside the sleeve plate 31; two lead screws 34, which are disposed at opposite ends and rotatably connected to the inner wall of the sleeve plate 31. The two lead screws 34 are fixedly connected to a connecting rod 35 at their ends with opposite threads and close to each other. A second bevel gear 36 that meshes with the first bevel gear 33 is fixed on the connecting rod 35; and a guide rod 37, which is fixedly connected to the inner wall of the sleeve plate 31 at both ends. A movable plate 38 that is threadedly connected to the lead screw 34 is sleeved on the guide rod 37. The movable plates 38 are distributed on both sides of the connecting rod 35. An extension plate 39 is fixedly disposed on both sides of the movable plate 38. One end of the extension plate 39 outside the sleeve plate 31 is fixedly connected to the support plate 1.

[0021] When controlling the two support plates 1 to move away from each other, turn the handle 32. The handle 32 drives the first bevel gear 33 to rotate. The first bevel gear 33 drives the second bevel gear 36, the connecting rod 35 and the lead screw 34 to rotate. The rotation of the lead screw 34 can cause the moving plates 38 on both sides to push the extension plates 39 away from each other along the guide rod 37. The movement of the extension plates 39 on both sides away from each other can push the support plates 1 on both sides away from each other, and then gradually tighten the safety net 6.

[0022] like Figure 3 As shown in the preferred embodiment of this utility model, the disassembly and assembly mechanism 4 includes: a groove 41, which is fixedly installed on the support plate 1 and has a positioning hole, and the hanging ring 5 can be placed in the groove 41; a sliding column 42, one end of which is fixedly connected to the groove 41, and the other end of the sliding column 42 is fixedly connected to a fixing plate 43, and a threaded column 44 is rotatably connected between the fixing plate 43 and the groove 41, and a handle 45 is fixedly connected to the end of the threaded column 44; a lifting plate 46, which is slidably sleeved on the sliding column 42 and threadedly connected to the threaded column 44, and a limiting column 47 is fixedly provided on the lifting plate 46, the end of the limiting column 47 is configured to cooperate with the positioning hole, and the hanging ring 5 placed in the groove 41 can be sleeved on the limiting column 47.

[0023] When removing the hanging ring 5, turn the handle 45. The handle 45 drives the threaded column 44 to rotate. The rotation of the threaded column 44 will cause the lifting plate 46 and the limiting column 47 to move downward along the sliding column 42. The downward movement of the limiting column 47 will disengage from the hanging ring 5, thus making it convenient to remove and replace the hanging ring 5 and the safety net 6.

[0024] like Figure 1As shown, in a preferred embodiment of the present invention, the stabilizing mechanism 7 includes: a connecting plate 71, which is fixedly installed on the lower side of the support plate 1, a hydraulic push rod 72 is fixedly installed on the connecting plate 71, and a stabilizing plate 73 is fixedly connected to the power output end of the hydraulic push rod 72, and the stabilizing plate 73 has an opening for the passage of the moving wheel 2; a guide post 74, which is fixedly installed on the connecting plate 71, and a guide sleeve 75 fixedly connected to the stabilizing plate 73 is sleeved on the guide post 74.

[0025] After the fall protection net is moved to the designated position, the hydraulic push rod 72 is activated. The hydraulic push rod 72 drives the stabilizing plate 73 and the guide sleeve 75 to move downward along the guide post 74. The downward movement of the stabilizing plate 73 will gradually suspend the moving wheel 2 in the air. With the support of the stabilizing plate 73, the fall protection net can be kept stable.

[0026] like Figure 1 As shown, in a preferred embodiment of the present invention, it further includes: an inclined plate 8, which is fixedly installed on the upper side of the support plate 1, and a buffer pad 9 is provided on the inclined plate 8.

[0027] If a construction worker accidentally falls and does not land precisely on the safety net 6, the worker will land on the cushioning pad 9 of the inclined plate 8. The cushioning pad 9 can effectively protect the worker's safety. Then, guided by the inclined plate 8, the worker can land stably on the safety net 6.

[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
