Description

Technical Field

[0001] This utility model relates to the field of safety protection nets for building construction, specifically a movable safety protection net for building construction. Background Technology

[0002] Construction refers to the production activities during the implementation phase of an engineering project. It is the process of building various types of structures, or the process of turning the lines on design drawings into physical objects at designated locations. Construction safety nets are indispensable safety facilities in the construction process.

[0003] The existing Chinese patent announcement number CN222009682U, entitled "A Safety Net for Construction," explicitly states in its abstract that "This utility model discloses a safety net for construction, including a fixed frame. The inner wall of the fixed frame has four hanging holes. The fixed frame contains a protective sheet. Two hooks are fixedly connected to the left and right sides of the protective sheet. The ends of the four hooks furthest from the protective sheet are respectively hooked to the four hanging holes. Two sets of retaining rings are fixedly connected to the inner wall of the fixed frame. Each set of retaining rings has a crossbar inside. This device uses rubber strips to fix the protective net around its perimeter, making the dustproof net more robust and durable, achieving the effect of reuse and cost savings. The dustproof cotton inside the net can effectively absorb construction dust, achieving a better dustproof effect. The crossbars on the upper and lower sides of the rubber strips allow for better flattening and installation of the dustproof net. The retaining rings at the top and bottom allow for quick installation of the dustproof net, saving workers' installation time and reducing installation costs."

[0004] However, during the current short-term construction process, if it is necessary to carry out construction in other locations after the completion of the construction, the safety nets will need to be moved by the workers. Since the safety nets are large and usually heavy, they are inconvenient to move. Currently, some safety nets are equipped with wheels at the bottom for easy movement, but in actual movement, due to their large size, they may still be inconvenient to move when passing through narrow places. Utility Model Content

[0005] The purpose of this utility model is to provide a movable safety net for building construction, so as to solve the problem of inconvenience in moving the net mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A movable safety net for construction includes a flexible safety net and two support columns. The support columns are provided with mounting bases at their bottoms and a winding assembly is provided inside the support columns.

[0008] The winding assembly includes a winding groove, and a rotating rod is rotatably disposed inside the winding groove.

[0009] In a preferred embodiment of this utility model, the flexible protective net is connected to two rotating rods at both ends, a dividing rod is provided at the middle position of the flexible protective net, and a universal brake wheel is provided at the bottom of the mounting base.

[0010] In a preferred embodiment of this utility model, a first synchronous wheel is provided at the bottom of the rotating rod, a mounting groove is provided on the mounting base, and a second synchronous wheel is rotatably provided at the bottom of the mounting groove. The first synchronous wheel and the second synchronous wheel are engaged by a synchronous belt.

[0011] In a preferred embodiment of this utility model, a hexagonal groove is provided on the inner side of the second synchronous pulley, a hexagonal rod is slidably disposed inside the hexagonal groove, a hexagonal opening is provided at the bottom of the hexagonal groove, the hexagonal rod is disassembled and assembled in the hexagonal opening, and a spring is provided on the outer side of the top of the hexagonal rod.

[0012] In a preferred embodiment of the present invention, a first pull rod is provided on the inner side of the top of the hexagonal rod, and a connector is provided on the outer side of the top of the first pull rod, with the top of the first pull rod rotatably mounted on the inner side of the connector.

[0013] In a preferred embodiment of the present invention, a slider is provided on one side of the connector, and a sliding groove is provided on the upper side of the mounting groove, wherein the slider and the sliding groove are slidably connected.

[0014] In a preferred embodiment of this utility model, a threaded opening is provided at the top of the slide groove, and a second pull rod is movably disposed inside the threaded opening. The bottom of the second pull rod is rotatably connected to the slider, and a threaded post is provided at the bottom of the second pull rod. The threaded post is threadedly connected to the threaded opening.

[0015] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention.

[0016] Beneficial effects: By pulling the first lever at the bottom, the hexagonal rod is disassembled in the hexagonal opening. The first lever can then be rotated, causing the second synchronous wheel at the bottom to rotate. Through the synchronous wheel and synchronous belt, the rotating rod is driven to rotate. Rotating the rotating rod causes the flexible protective netting to be wound into the winding groove. After rotation, a spring pushes the hexagonal rod, positioning it above the hexagonal opening. Slightly rotating the hexagonal rod again aligns it with the opening and inserts it, thus fixing the rod in place. This significantly reduces the overall structure's volume, allowing for easy movement without disassembly. The bottom universal brake wheel facilitates movement, making it even more convenient. Furthermore, the significantly reduced overall size makes it easier to move in narrow spaces.

[0025] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0026] Please refer to Figures 1-5 This utility model discloses a movable safety net for construction, comprising a flexible safety net 1 and two support columns 11. The flexible safety net 1 is the main body of the safety net, and the two support columns 11 are the installation structure. A mounting base 13 is provided at the bottom of each support column 11, serving as the bottom structure to support the upper structure. A winding assembly is provided inside each support column 11, including a winding groove 14. A rotating rod 15 is rotatably mounted inside the winding groove 14. Both ends of the flexible safety net 1 are connected to the rotating rods 15 on both sides. By rotating the rotating rods 15, the flexible safety net 1 is wound into the winding groove 14, greatly reducing the overall volume of the structure and allowing for easy movement without disassembly. A dividing rod 12 is provided at the middle of the flexible safety net 1 to separate the two ends. A universal brake wheel 2 is provided at the bottom of the mounting base 13 to drive the overall structure for easier movement.

[0027] A first synchronous pulley 21 is provided at the bottom of the rotating rod 15. A mounting groove 23 is provided on the mounting base 13. The mounting groove 23 is a mounting structure. A second synchronous pulley 22 is rotatably mounted at the bottom of the mounting groove 23. The first synchronous pulley 21 and the second synchronous pulley 22 are meshed by a synchronous belt. A hexagonal groove 24 is provided on the inner side of the second synchronous pulley 22. A hexagonal rod 31 is slidably mounted inside the hexagonal groove 24. A hexagonal opening 25 is provided at the bottom of the hexagonal groove 24. The hexagonal opening 25 is fixedly connected to the mounting base 13. The hexagonal groove 24 rotates with the second synchronous pulley 22. The hexagonal rod 31 is installed and removed within the hexagonal opening 25. A spring 3 is provided on the outer top of the hexagonal rod 31. The top of the hexagonal rod 31 contacts the inner top of the mounting groove 23, but is not connected. A first pull rod 32 is provided on the inner side of the top of the hexagonal rod 31. That is, by pulling the first pull rod 32 at the bottom, the hexagonal rod 31 is disassembled in the hexagonal opening 25. At this time, the first pull rod 32 can be rotated, which drives the second synchronous wheel 22 at the bottom to rotate. Through the synchronous wheel and synchronous belt, the rotation rod 15 is driven to rotate. After the rotation is completed, the spring 3 pushes the hexagonal rod 31 so that the hexagonal rod 31 is above the hexagonal opening 25. Then, the hexagonal rod 31 is rotated slightly so that the hexagonal rod 31 is aligned with the hexagonal opening 25 and inserted, thus fixing the hexagonal rod 31.

[0028] A connector 33 is provided on the outer side of the top of the first pull rod 32. The top of the first pull rod 32 is rotatably mounted on the inner side of the connector 33. A slider 34 is provided on one side of the connector 33. A sliding groove 4 is provided on one side above the mounting groove 23. The slider 34 is slidably connected to the sliding groove 4. A threaded opening 41 is provided on the top of the sliding groove 4. A second pull rod 42 is movably mounted inside the threaded opening 41. The bottom of the second pull rod 42 is rotatably connected to the slider 34. A threaded post 43 is provided on the bottom of the second pull rod 42. The threaded post 43 is threadedly connected to the threaded opening 41. By pulling the second pull rod 42 at the top, the first pull rod 32 and the hexagonal rod 31 are pulled at the same time. At this time, the hexagonal rod 31 is disassembled in the hexagonal opening 25, and the threaded post 43 is screwed into the threaded opening 41, thus fixing the position of the first pull rod 32 and the hexagonal rod 31. At this time, when the first pull rod 32 is rotated, it is not necessary to pull it.

[0029] The working principle of this utility model is as follows: By pulling the first pull rod 32 at the bottom, the hexagonal rod 31 is disassembled in the hexagonal opening 25. At this time, the first pull rod 32 can be rotated, which drives the second synchronous wheel 22 at the bottom to rotate. Through the synchronous wheel and synchronous belt, the rotating rod 15 is driven to rotate. By rotating the rotating rod 15, the flexible protective net 1 is wound into the winding groove 14. After the rotation is completed, the spring 3 pushes the hexagonal rod 31 so that the hexagonal rod 31 is above the hexagonal opening 25. Then, the hexagonal rod 31 is rotated slightly to align with the hexagonal opening 25. Inserting the hexagonal rod 31 into the opening 25 will fix the hexagonal rod 31, thus greatly reducing the volume of the overall structure. It can be moved easily without disassembly. The overall structure can be moved by the bottom universal brake wheel 2, making it easier to move. By pulling the second pull rod 42 at the top, the first pull rod 32 and the hexagonal rod 31 are pulled at the same time. At this time, the hexagonal rod 31 is disassembled in the hexagonal opening 25, and the threaded post 43 is screwed into the threaded opening 41, thus fixing the position of the first pull rod 32 and the hexagonal rod 31. At this time, when rotating the first pull rod 32, there is no need to pull it.
