Utility Model Content

[0003] The purpose of this invention is to overcome the problems of the prior art and provide a safe and easy-to-use anti-fall device for decoration and construction.

[0004] To achieve the above objectives, the present invention adopts the following solution:

[0005] A fall protection device for decoration and construction, comprising:

[0006] A load-bearing base that is movable, wherein the load-bearing base is provided with multiple support components that can support it to detach from the bottom surface;

[0007] The operating basket is provided with a lifting mechanism that connects the two and changes the height of the operating basket relative to the load-bearing base. The operating basket is provided with a protruding support column.

[0008] A fall arrestor assembly is detachably connected to a support column and is installed on the top of the operating basket. The fall arrestor assembly includes two mesh frames that are spliced ​​together. The middle of each mesh frame is set in a semi-circular arc so that the two mesh frames can form a receiving groove to accommodate the support column after being spliced ​​together. Each mesh frame is also provided with multiple support lines that can cooperate to provide support. A support plate that can abut against the top of the support column is also provided between the two mesh frames.

[0009] One of the two mesh frames is provided with an opening, and the mesh frame is provided with a connecting frame that can rotate relative to it to open or close the opening, and the connecting frame is provided with the support line.

[0010] The fall protection net assembly is arranged in the shape of a regular polygon, and the support space formed by the fall protection net assembly faces upward.

[0011] The outer sides of the two aforementioned mesh frames are also fitted with protective sleeves.

[0012] Each of the aforementioned mesh frames is also provided with lifting lugs.

[0013] The lifting mechanism includes a first rotating frame rotatably connected to a load-bearing base, a second rotating frame rotatably connected to the first rotating frame, the lower end of the second rotating frame slidably connected to the load-bearing base, a connecting frame connecting the upper end of the second rotating frame and the upper end of the first rotating frame, the upper end of the second rotating frame rotatably connected to the connecting frame, the upper end of the first rotating frame slidably connected to the connecting frame, and a first driving member between the first rotating frame and the load-bearing base that can push the first rotating frame to move, thereby causing the connecting frame to move up and down relative to the load-bearing base.

[0014] The first rotating frame has a horizontal first connecting shaft at its upper end, and first rollers are connected to both ends of the first connecting shaft. The connecting frame has a first sliding groove that allows the first rollers to slide.

[0026] The present invention will be further described in detail below with reference to embodiments:

[0027] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0028] like Figures 1 to 6As shown, a fall prevention device for decoration and construction includes: a load-bearing base 1, which is movable, and the load-bearing base 1 is provided with multiple support components 2 that can support it to detach from the bottom surface; an operating basket 3, and the operating basket 3 is provided with a lifting mechanism 4 that can connect the two and change the height of the operating basket 3 relative to the load-bearing base 1, and the operating basket 3 is provided with a protruding support column 31; a fall prevention net assembly 5, which is detachably connected to the support column 31 and is provided on the top of the operating basket 3. The fall prevention net assembly 5 includes two mesh frames 51 spliced ​​together, and the middle of each mesh frame 51 is set in a semi-circular arc so that the two mesh frames can form a receiving groove 52 to accommodate the support column 31 after splicing. Each mesh frame 51 is also provided with multiple support lines 53 that can cooperate to support it, and a support plate 54 that can abut against the support column 31 is provided between the two mesh frames 51.

[0029] When this utility model is needed, the worker enters the operating basket 3, and then the load-bearing base 1 is dragged to the required position by an external trailer. The lifting mechanism 4 is then activated, and the lifting mechanism 4 raises the operating basket 3 to the predetermined position. Due to the setting of the fall protection net component 5, it can prevent objects from falling from heights. At the same time, the setting of the operating basket 3 can also provide workers with room to move around. Compared with directly using scaffolding, it is safer. Moreover, the fall protection net component 5 is made of two mesh frames 51 spliced ​​together and fixed to the support column 31 by the support plate 54. When the fall protection net component 5 is not needed, it can be disassembled, making it more flexible to use. The setting of the support line 53 can strengthen the tension of the support and provide more effective protection.

[0030] One of the two mesh frames 51 is provided with an opening 511. The mesh frame 51 is provided with a connecting frame that can rotate relative to it to open or close the opening 511. The connecting frame is provided with the support line 53. The support line 53 is a steel wire or other metal wire with sufficient supporting tension to prevent heavy objects such as stones from falling and hitting the operator.

[0031] The fall protection net component 5 is arranged in the form of a regular polygon, and the receiving space 500 formed by the fall protection net component 5 faces upward. The fall protection net is hexagonal and octagonal.

[0032] The outer sides of the two mesh frames 51 are also fitted with protective sleeves to prevent stones from falling.

[0033] Each of the aforementioned mesh frames 51 is also provided with a lifting lug 512 for easy gripping of the mesh frame 51.

[0034] The lifting mechanism 4 includes a first rotating frame 41 rotatably connected to the load-bearing base 1. A second rotating frame 42, which can rotate relative to the first rotating frame 41, is connected to the first rotating frame 41. The lower end of the second rotating frame 42 is slidably connected to the load-bearing base 1. A connecting frame is connected between the upper end of the second rotating frame 42 and the upper end of the first rotating frame 41. The upper end of the second rotating frame 42 is rotatably connected to the connecting frame, and the upper end of the first rotating frame 41 is slidably connected to the connecting frame. A first driving member 44, which can push the first rotating frame 41 to move, thereby causing the connecting frame to move up and down relative to the load-bearing base 1, is also provided between the first rotating frame 41 and the load-bearing base 1. The first driving member 44 is a cylinder. The output shaft of the cylinder drives the first rotating frame 41 to rotate, causing the first rotating frame 41 to drive the second rotating frame 42 to rotate, unfold, or fold, making operation more convenient.

[0035] The first rotating frame 41 has a transverse first connecting shaft 411 at its upper end, and first rollers 412 are connected to both ends of the first connecting shaft 411. The connecting frame has a first sliding groove 431 for the first rollers 412 to slide on. The second rotating frame 42 has a transverse second connecting shaft 421 at its lower end, and second rollers 422 are connected to both ends of the second connecting shaft 421. The load-bearing base 1 has a second sliding groove 11 for the second rollers 422 to slide on. The first rollers 412 and the first sliding groove 431 facilitate the sliding of the upper end of the first rotating frame 41 along the connecting frame. At the same time, the second rollers 422 and the second sliding groove 11 facilitate the sliding of the lower end of the second rotating frame 42 along the load-bearing base 1, making the rotation, unfolding, or folding of the first rotating frame 41 and the second rotating frame 42 smoother.

[0036] The support assembly 2 includes a mounting base 21 connected to the side of the load-bearing base 1. A support leg 22, which can rotate relative to the mounting base 21, is connected to the mounting base 21. A support seat 23, which can rotate relative to the support leg 22, is connected to the end of the support leg 22. The support seat 23 can rotate relative to the support leg 22, allowing it to adapt to different floor surfaces, providing more stable support and enhancing safety during use.

[0037] The supporting leg 22 includes a rotating seat 221 rotatably connected to the mounting base 21. Multiple connecting plates 222 are connected to the end of the rotating seat 221. A first supporting rod 223, rotatable relative to the connecting plates 222, is connected between them. The supporting seat 23 is rotatably connected to the first supporting rod 223. A second driving member 224, rotatable relative to the connecting plates 222, is also connected between them. The output shaft of the second driving member 224 is rotatably connected to the first supporting rod 223. The second driving member 224 is a cylinder. When the output shaft extends outward, it pushes the first supporting rod 223, causing the output shaft of the second driving member 224 to rotate relative to the first supporting rod 223. Simultaneously, the second driving member 224 rotates relative to the connecting plates 222, and the first supporting rod 223 rotates relative to the connecting plates 222. This causes the first supporting rod 223 to rotate downward relative to the connecting plates 222, gradually supporting the supporting seat 23 on the ground and lifting the load-bearing base 1 upward.

[0038] The load-bearing base 1 is also equipped with multiple rollers 12. The rollers 12 facilitate the movement of the anti-fall device used in this decoration and construction work, allowing the anti-fall device to be fitted close to the exterior wall, making it convenient for workers to carry out maintenance and construction.

[0039] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
