DETAILED DESCRIPTION

[0018] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limitations on the present invention. On the contrary, the embodiments of the present invention include all changes, modifications, and equivalents that fall within the spirit and connotation of the appended claims.

[0019] The horizontal cantilever net support device of the embodiment of the utility model is described below with reference to the accompanying drawings.

[0020] like Figure 1-Figure 3 As shown, the horizontal net supporting device of the embodiment of the utility model may include a mounting plate 10, two supporting mechanisms 20, two stretching mechanisms 30, two buffer mechanisms 50, two supporting rods 60 and a driving assembly 70.

[0021] One end of the two supporting mechanisms 20 is pivotally connected to the mounting plate 10 , respectively, and the two supporting mechanisms 20 are arranged side by side. Two first sliding grooves 101 are provided on the mounting plate 10 near the bottom of the two supporting mechanisms 20 .

[0022] In the embodiment of the utility model, in order to facilitate the fixing of the mounting plate 10 on the building wall where the safety net needs to be erected, a through hole for fixing the safety plate can be provided on the mounting plate 10.

[0023] The two stretching mechanisms 30 are respectively arranged on the corresponding supporting mechanisms 20, and a safety net 40 is arranged between the two stretching mechanisms 30. It should be noted that the safety net described in this embodiment is a flexible net and is foldable.

[0024] The two buffer mechanisms 50 are respectively disposed in the corresponding first sliding grooves 101 , one ends of the two support rods 60 are respectively pivotally connected to the corresponding buffer mechanisms 50 , and the other ends of the two support rods 60 are respectively pivotally connected to the corresponding support mechanisms 20 .

[0025] The driving assembly 70 is disposed on the two supporting mechanisms 20 , and the driving assembly 70 is connected to the two stretching mechanisms 30 respectively.

[0026] In one embodiment of the present invention, Figure 1 As shown, the support mechanism 20 may include a support arm 21 and a guide wheel 22 .

[0027] One end of the support arm 21 is pivotally connected to the mounting plate 10, the middle of the support arm 21 is pivotally connected to the other end of the support rod 60, and a second slide groove 201 is provided on the side wall of the support arm 21, and the guide wheel 22 is rotatably arranged on the other end wall of the support arm 21. It should be noted that the support arm 21 described in this embodiment can be pivotally connected to the mounting plate 10 and the support rod 60 respectively through a pin shaft.

[0028] In one embodiment of the present invention, Figure 1 and Figure 3 As shown, the stretching mechanism 30 may include a plurality of first sliders 31 and a steel wire rope 32, wherein the plurality of first sliders 31 are equidistantly arranged side by side and slidably disposed in the second slide groove 201, for example, the plurality of first sliders 31 may be 5, 6, 7, 8, 9, 10, 11 first sliders 31, etc., and the specific number of sliders used may be selected according to actual conditions and is not limited here, and each first slider 31 is fixedly connected to one side of the safety net 40. It should be noted that the first slider 31 described in this embodiment is fixedly connected to the upper corner point of the folded fully net 40.

[0029] One end of the steel wire rope 32 is fixedly connected to the end wall of the second slide groove 201 , and the other end of the steel wire rope 32 passes through the second slide groove 201 and passes around the guide wheel 22 , and the steel wire rope 32 is fixedly connected to the plurality of first sliders 31 , respectively.

[0030] It should be noted that the initial positions of the multiple first sliders 31 described in this embodiment are gathered in the second slide groove 201 and close to one end of the mounting plate 10. At this time, the safety net 40 is folded together as the multiple first sliders 31 gather. When the safety net 40 is unfolded, the safety net 40 is spread out in a wave-like manner. It can be understood that by unfolding the safety net 40 in a wave-like manner compared to unfolding the safety net in a plane, the support strength of the safety net 40 can be enhanced, and it can also play a role in buffering falling objects, effectively improving the safety of the construction site, wherein the falling objects can be stones, gravel or metal parts in the building, etc.

[0031] In one embodiment of the present invention, Figure 1 As shown, the buffer mechanism 50 may include a second slider 51 and a spring 52 , wherein the second slider 51 is slidably disposed in the first slide groove 101 , and the second slider 51 is pivotally connected to one end of the support rod 60 .

[0032] The spring 52 is disposed in the first sliding groove 101 , and one end of the spring 52 is fixedly connected to the second sliding block 51 , and the other end of the spring 52 is fixedly connected to the bottom wall of the first sliding groove 101 .

[0033] In one embodiment of the present invention, Figure 1-Figure 3 As shown, the driving assembly 70 may include a connecting shaft 71, two winding rollers 72, a ratchet 73, a pawl 74 and a driving handle 75, wherein the connecting shaft 71 is rotatably arranged between the two support arms 21, and the connecting shaft 71 is arranged close to the mounting plate 10, and the two winding rollers 72 are respectively arranged on the connecting shaft 71, and the two winding rollers 72 are respectively connected to the other end of the corresponding steel wire rope 32.

[0034] The ratchet 73 is disposed on the connecting shaft 71 , one end of the pawl 74 is pivotally connected to the support arm 21 close to the ratchet 73 , the other end of the pawl 74 abuts against the ratchet 73 , and the driving handle 75 is fixedly connected to one end of the connecting shaft 71 .

[0035] Specifically, when it is necessary to set a safety net outside the construction building, the staff first needs to fix the mounting plate 10 on the wall of the construction building. Then, the staff manually rotates the driving handle 75 in the forward direction (clockwise), and the rotating driving handle 75 drives the two winding rollers 72 and the ratchet 73 to rotate synchronously through the connecting shaft 71, and the two rotating winding rollers 72 reel the wire rope 32. As the two winding rollers 72 synchronously reel the wire ropes 32 in the two stretching mechanisms 30, the moving wire ropes 32 drag the multiple first sliders 31 to move and slide in the corresponding second slide groove 201, so that the multiple first sliders 31 gathered together are equidistantly unfolded side by side in the second slide groove 201. Thereby, the folded safety net 40 is unfolded into a wave shape, which is used to intercept (catch) objects falling from high altitude. In this way, the difficulty of manually installing the safety net at high altitude can be effectively reduced, and the operation process is simplified.

[0036] The pawl 74 can prevent the ratchet 73 from rotating in the reverse direction (counterclockwise), thereby preventing the two winding rollers 72 from rotating in the reverse direction, thereby preventing the safety net 40 from shrinking when hit by objects falling from a high altitude, resulting in a smaller deployment range of the safety net 40, thereby affecting the protection range of the safety net 40.

[0037] When the safety net 40 receives an object falling from a high altitude, the object will impact the safety net 40, and the safety net 40 will be deformed after being impacted. At the same time, the impacted safety net 40 applies a downward force to the two support arms 21. At this time, the two support arms 21 are forced to flip downward, and the second slider 51 is pushed to slide in the first slide groove 101 through the support rod 60. The sliding second slider 51 compresses the spring 52, and the elastic deformation of the spring 52 buffers the impact force on the safety net 40, thereby preventing objects falling from a high altitude from causing harm to personnel, greatly improving the safety of the construction site.

[0038] When the safety net 40 needs to be folded together, the staff only needs to flip the pawl 74 to release the limit of the pawl 74 to the ratchet 73. Then, the staff hooks the safety net 40 by hook and pulls it back, and the safety net 40 can be folded and put away, which is simple and convenient to operate.

[0039] In summary, the horizontal cantilever net support device of the embodiment of the utility model can effectively reduce the difficulty of manually installing the safety net at high altitude by optimizing the installation method of the safety net, simplifying the operation process, and at the same time, by setting a buffer mechanism, it can buffer the falling objects to prevent the falling objects from high altitude from causing harm to personnel, thereby greatly improving the safety of the construction site.
