Description

Technical Field

[0001] This application relates to the field of construction safety net technology, and in particular to fall protection nets for building construction. Background Technology

[0002] In the construction industry, fall arrest nets are an important safety protection device for high-altitude operations. They are widely used in areas such as building facades and floor edges to intercept falling objects or people and prevent direct falls to the ground.

[0003] Traditional fall arrest nets typically consist of a metal frame and a highly elastic nylon or polyester mesh. They are fixed to the building structure by the frame and rely on the elastic deformation of the mesh itself to buffer impact energy.

[0004] In existing technology, when a fall arresting net is impacted by a falling object, the net body undergoes significant elastic deformation due to the material properties to absorb kinetic energy; however, after the impact ends, the net body will quickly rebound under the action of elastic restoring force, generating an upward reverse force.

[0005] If the falling object (such as tools, building material fragments, etc.) does not come to a complete stop after the first impact, the rebound process can easily cause the object to be thrown up a second time, or even eject some of the fragments outside the construction area, causing secondary injury to personnel or equipment below. In addition, if a person's body comes into contact with the rebound net when falling, the impact may aggravate the degree of injury.

[0006] In other words, the existing technology has the following technical problems: ordinary fall protection nets rebound after being impacted, causing secondary injuries. Therefore, a construction fall protection net is proposed to address the above problems. Summary of the Invention

[0007] This embodiment provides a construction fall protection net to solve the problem that ordinary fall protection nets in the prior art rebound after being impacted, causing secondary injuries.

[0008] According to one aspect of this application, a construction fall protection net is provided, the construction fall protection net comprising:

[0009] A rectangular fixed frame, wherein a protective net is fixedly connected to the inner sidewall of the rectangular fixed frame;

[0010] A floating support assembly is fixedly installed on the bottom surface of a rectangular fixed frame, and the floating support assembly can move downward when the protective net is impacted;

[0011] An anti-rebound assembly includes a linkage structure and a winding traction structure. The winding traction structure is fixedly installed at the floating support assembly and is connected to the protective net. The linkage structure is connected to the floating support assembly. The linkage structure is used to automatically drive the winding traction structure to wind and pull when the floating support assembly moves downward.

[0012] Furthermore, the floating support assembly includes a rectangular support sleeve, a rectangular moving rod, a fixed base plate, and a one-way limiting structure. Four rectangular moving rods are provided, and the four rectangular moving rods are respectively fixed at the four corners of the bottom surface of the rectangular fixed frame. The rectangular moving rods slide with the rectangular support sleeve, and the fixed base plate is fixedly connected to the bottom surface of the rectangular support sleeve.

[0013] Furthermore, the unidirectional limiting structure includes a connecting plate, locking teeth, locking tenons, a moving rod, a limiting sleeve rod, a limiting spring, and a return spring. The bottom end of the rectangular moving rod is fixedly connected to the connecting plate, and several locking teeth are provided on the side wall of the connecting plate.

[0014] Furthermore, a limiting sleeve rod is fixedly connected to the inner cavity side wall of the rectangular support sleeve rod, and a movable rod is slidably connected in the inner cavity of the limiting sleeve rod. One end of the movable rod passes through the inner cavity wall of the rectangular support sleeve rod and extends to the outside of the wall. A latch is fixedly connected to the other end of the movable rod. One end of a limiting spring is fixedly connected to one side of the latch. The other end of the limiting spring is fixedly connected to the inner cavity wall of the rectangular support sleeve rod, and the limiting spring is in a compressed state.

[0015] Furthermore, a return spring is fixedly connected to one end of the bottom of the connecting plate, and the other end of the return spring is fixedly connected to the bottom wall of the inner cavity of the rectangular support sleeve.

[0016] Furthermore, the winding traction structure includes a fixed bracket, a winding roller, a traction cable, and a guide wheel. The fixed bracket is fixedly installed on the upper surface of the fixed base plate, and the winding roller is rotatably connected to the inner side of the fixed bracket. The traction cable is wound onto the winding roller.

[0017] Furthermore, the guide wheel is fixedly installed on the upper surface of the fixed base plate, and one end of the traction cable passes around the guide wheel and extends to the middle of the protective net and is fixedly connected to the protective net.

[0018] Furthermore, the linkage structure includes a gear and a rack, the gear is disposed on the side wall of the fixed bracket and is rotatably connected to the fixed bracket, and the gear is coaxially fixedly connected to the take-up roller.

[0019] Furthermore, a movable crossbeam is slidably connected to the side wall of the rectangular support sleeve, and the movable crossbeam is fixedly connected to the rectangular movable rod.

[0020] Furthermore, a rack is fixedly connected to the bottom surface of the movable crossbeam, and the rack meshes with the gear.

[0021] In order to solve the problem that ordinary fall arrest nets in the prior art are prone to rebound and cause secondary injuries after being impacted due to their inherent elasticity, this application designs an anti-rebound component. By using the anti-rebound component in conjunction with the floating support component, the anti-rebound component can be automatically driven to move after the net is impacted, and the floating support component can be automatically pulled and limited. This pulling action suppresses the rebound of the net and effectively reduces the problem of secondary injuries caused by rebound. Attached Figure Description

[0038] Please see Figure 1-6 As shown, a construction fall protection net includes:

[0039] A rectangular fixed frame 1, wherein a protective net 2 is fixedly connected to the inner side wall of the rectangular fixed frame 1;

[0040] A floating support component 3 is fixedly installed on the bottom surface of the rectangular fixed frame 1. The floating support component 3 can move downward when the protective net 2 is impacted.

[0041] The anti-rebound component 4 includes a linkage structure and a winding traction structure. The winding traction structure is fixedly installed at the floating support component 3 and is connected to the protective net 2. The linkage structure is connected to the floating support component 3. The linkage structure is used to automatically drive the winding traction structure to wind and pull when the floating support component 3 moves downward.

[0042] By combining the floating support with the linkage traction mechanism through the above technical solution, the net body is applied with directional tension force while absorbing the impact through impact-triggered mechanical linkage, so as to achieve dynamic cancellation of the rebound force.

[0043] The floating support assembly 3 includes a rectangular support sleeve 301, a rectangular moving rod 302, a fixed base plate 303, and a one-way limiting structure. There are four rectangular moving rods 302, which are respectively fixed at the four corners of the bottom surface of the rectangular fixed frame 1. The rectangular moving rods 302 and the rectangular support sleeve 301 are slidably engaged. The fixed base plate 303 is fixedly connected to the bottom surface of the rectangular support sleeve 301.

[0044] The one-way limiting structure includes a connecting plate 305, a locking tooth 306, a locking tenon 307, a moving rod 308, a limiting sleeve rod 309, a limiting spring 310, and a return spring 311. The bottom end of the rectangular moving rod 302 is fixedly connected to the connecting plate 305, and a plurality of locking teeth 306 are provided on the side wall of the connecting plate 305.

[0045] A limiting sleeve 309 is fixedly connected to the inner cavity side wall of the rectangular support sleeve 301. A movable rod 308 is slidably connected in the inner cavity of the limiting sleeve 309. One end of the movable rod 308 penetrates the inner cavity wall of the rectangular support sleeve 301 and extends to the outside of the wall. A latch 307 is fixedly connected to the other end of the movable rod 308. One end of a limiting spring 310 is fixedly connected to one side of the latch 307. The other end of the limiting spring 310 is fixedly connected to the inner cavity wall of the rectangular support sleeve 301. The limiting spring 310 is in a compressed state. Through this technical solution, when the protective net 2 is impacted, the impact force will push the rectangular fixed frame 1 to move downward, thereby driving the rectangular movable rod 302 to move downward. The downward movement of the rectangular movable rod 302 can also drive the connecting plate 305 to move downward. Through the setting of the latch 307, the latch 306 can play a one-way limiting role, so that the rectangular movable rod 302 can only move downward and cannot move upward.

[0046] One end of a return spring 311 is fixedly connected to the bottom end of the connecting plate 305, and the other end of the return spring 311 is fixedly connected to the bottom wall of the inner cavity of the rectangular support sleeve 301. With this technical solution, after a protection operation is completed, the return spring 302 can be reset by manually moving one end of the moving rod 308. The movement of the moving rod 308 can drive the latch 307 to move, and the movement of the latch 307 can separate it from the latch tooth 306. Since the limiting function of the latch 307 is lost, the return spring 311 can push the rectangular moving rod 302 to move upward and reset.

[0047] The winding traction structure includes a fixed bracket 401, a winding roller 402, a traction cable 403, and a guide wheel 404. The fixed bracket 401 is fixedly installed on the upper surface of the fixed base plate 303. The winding roller 402 is rotatably connected to the inner side of the fixed bracket 401. The traction cable 403 is wound and connected to the winding roller 402.

[0048] The guide wheel 404 is fixedly installed on the upper surface of the fixed base plate 303, and one end of the traction cable 403 passes around the guide wheel 404 and extends to the middle of the protective net 2 and is fixedly connected to the protective net 2.

[0049] The linkage structure includes a gear 405 and a rack 406. The gear 405 is disposed on the side wall of the fixed bracket 401 and is rotatably connected to the fixed bracket 401. The gear 405 is coaxially fixedly connected to the take-up roller 402. Through this technical solution, the rotation of the gear 405 can drive the take-up roller 402 to rotate.

[0050] A movable crossbeam 304 is slidably connected to the side wall of the rectangular support sleeve 301. The movable crossbeam 304 is fixedly connected to the rectangular movable rod 302. Through this technical solution, the movable crossbeam 304 can be moved by the downward movement of the rectangular movable rod 302.

[0051] A rack 406 is fixedly connected to the bottom surface of the movable crossbeam 304. The rack 406 meshes with the gear 405. Through this technical solution, when the protective net 2 is impacted, the rectangular fixed frame 1 moves downward. The downward movement of the rectangular fixed frame 1 can drive the movable crossbeam 304 to move downward, thereby driving the rack 406 to move downward. The downward movement of the rack 406 can drive the gear 405 to rotate. The rotation of the gear 405 can drive the winding roller 402 to rotate, thereby driving the traction cable 403 to move. Thus, the traction of the traction cable 403 can play the role of traction and limiting the protective net 2, preventing the protective net 2 from rebounding. While absorbing the impact, it applies a directional pulling force to the net body, realizing the dynamic cancellation of the rebound force, thereby avoiding the damage caused by secondary rebound.

[0052] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
