TECHNICAL FIELD
[0001] The utility model relates to building technology field especially, it relates to an emergency support safety device of adaptation building open space. BACKGROUND
[0002] Safety nets, also known as fall arrest safety nets, are protective devices designed to prevent people and objects from falling from heights. They come in various forms and are used in different scenarios, including but not limited to building edges, overhead facilities, construction sites, and special environments such as manholes and inspection wells. The primary purpose of safety nets is to provide a buffer zone in the event of a fall, thereby reducing potential injuries. They are made of high-strength steel wires and other durable materials such as nylon, vinylon, polyester, polypropylene, polyethylene, and silk. To prevent construction workers from being injured by falling objects from heights and to address potential falling objects from above in public buildings, numerous fall arrest safety nets are often installed.
[0003] The safety nets in the prior art need to be installed straight. When an object falls onto the safety net, the straight safety net will have a certain reaction force on the falling object. The safety net made of hard material may cause damage to the object. Moreover, the vertical falling object may break the safety net when it hits the safety net, causing the object to continue falling and causing injury. Furthermore, to ensure the aesthetics and safety of the safety net during use, there is no emergency protection method that can be quickly assembled before a sudden falling event occurs around a building that does not have a safety net installed. The existing safety nets installed around buildings have a single protection method and do not have a self-adjusting function that can adapt to different forms, weights, and falling heights of falling objects for secondary emergency protection. In addition, during the maintenance of the safety net, it is found that during the regular or on-demand cleaning process of the debris on the safety net, it is necessary to use a climbing tool to climb up to the level of the safety net and use a tool to clean it. The safety net can also be removed and cleaned. Regardless of which method is used for cleaning, the corresponding cleaning process has relatively complicated operations, and there are safety hazards during the cleaning process. SUMMARY
[0004] The utility model discloses a kind of emergency support safety devices of adaptation building open space, to solve the shortcomings in prior art.
[0005] To achieve the above object, the utility model adopts the following technical scheme:
[0006] The utility model provides an emergency support safety device for the open space of building, including main support column, safety net body, two lateral elastic adjusting column, two elastic pieces, two connecting seat body and two lifting connecting seat, the main support column is vertically arranged, two lateral elastic adjusting column is vertically arranged in parallel in the both sides of main support column respectively, the top of each lateral elastic adjusting column corresponds to set up one connecting seat body, each lateral elastic adjusting column is connected with its corresponding connecting seat body through an elastic piece, safety net body sets up between two connecting seat body and two lifting connecting seat, one end of safety net body is connected with two connecting seat body respectively, the other end of safety net body is connected with two lifting connecting seat respectively, when safety net body is hit by falling object, safety net body makes reciprocating movement between two connecting seat body and two lifting connecting seat.
[0007] Compared with the prior art, the utility model has the advantages that:
[0008] The main support column, the safety net body, the two lateral elastic adjusting columns, the two elastic pieces, the two connecting seat bodies and the two lifting connecting seats cooperate with each other to realize rapid assembly and use performance in response to emergencies, and the self-cleaning and protection performance is improved. The utility model can be used as a temporary protection structure in response to emergencies, and can be used for the lasting protection of the enclosed open space of a public building, a building atrium or other open space around the building. The tightness of the safety net can be adjusted in time according to the weight of the falling object in an emergency. The specific advantages are:
[0009] 1. The elastic piece and the lifting connecting seat cooperate to realize multi-position vertical buffering effect. When a falling object or a falling object with heavy weight falls on the top of the safety net body, the two connecting seat bodies are subjected to the impact force generated by the falling object. With the cooperation between the two damping rods and the buffer springs, the impact force can be buffered and damped to a certain extent. The lifting connecting seat cooperates with the safety net body to realize synchronous buffering effect. Even if the impact force between the object and the safety net body is too large, the damage to the safety net body can be reduced, the falling object can be contained to prevent it from continuing to fall, and the safety performance and support performance of the safety net body during use can be improved.
[0010] 2. When the debris on the top of the safety net body needs to be cleaned, the two winding rollers are controlled to rotate, and the safety net body is released to fall. The safety net body falls at the same time, driving the falling objects on the net to fall down, which is convenient for subsequent collection. At the same time, the utility model can also adjust the release or tightening width of the safety net body through the control of the winding roller, so as to realize the mesh tightness state conversion process in response to different falling objects, which is beneficial to the durable use of the safety net body. The safety net body does not need to be disassembled for cleaning debris, which improves the efficiency of the staff in cleaning debris and reduces the risk of cleaning. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION
[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments.
[0023] Specific implementation method one: Combining Figures 1 to 10 This embodiment describes an emergency support safety net comprising a main support column 1, a safety net body 3, two lateral elastic adjustment columns 2, two elastic elements, two connecting seats 4, and two lifting connecting seats 22. The main support column 1 is vertically positioned, and the two lateral elastic adjustment columns 2 are vertically arranged side-by-side on either side of the main support column 1. Each lateral elastic adjustment column 2 has a corresponding connecting seat 4 at its top. Each lateral elastic adjustment column 2 is connected to its corresponding connecting seat 4 via an elastic element. The safety net body 3 is positioned between the two connecting seats 4 and the two lifting connecting seats 22. One end of the safety net body 3 is connected to each of the two connecting seats 4, and the other end is connected to each of the two lifting connecting seats 22. When the safety net body 3 is impacted by a falling object, it reciprocates between the two connecting seats 4 and the two lifting connecting seats 22. In this embodiment, the safety net body 3 is elastic, made of existing elastic material, and capable of stretching along its length, similar to the structural form of existing fall-prevention elastic nets.
[0024] Specific Implementation Method Two: This implementation method is a further limitation of Specific Implementation Method One. The safety net body 3 is a self-winding net body. The safety net body 3 includes a net body 3-1 and two winding rollers 3-2. The two winding rollers 3-2 are arranged horizontally side by side. Each winding roller 3-2 is provided with a corresponding connecting seat 4 and a corresponding lifting connecting seat 22. One end of each winding roller 3-2 is hinged to its corresponding connecting seat 4, and the other end of each winding roller 3-2 is hinged to its adjacent lifting connecting seat 22. The two sides of the net body 3-1 are respectively connected to the two winding rollers 3-2. The rotation directions of the winding rollers 3-2 are opposite. When the rotation directions of the two winding rollers 3-2 are both towards the net body 3-1, the net body 3-1 is in a state of being taut and closed on both sides. When the rotation directions of the two winding rollers 3-2 are both away from the net body 3-1, the net body 3-1 is in a state of being extended and formed into a concave pocket structure on both sides.
[0025] Both connecting seats 4 have rotatably mounted take-up rollers 3-2 inside, and the two ends of the safety net body 3 are respectively wound onto the surfaces of the two take-up rollers 3-2. Each connecting seat 4 has a first drive motor pre-installed inside the end near the side-mounted elastic adjustment column 2. The power output ends of the two first drive motors are connected to the rotating parts of the two take-up rollers 3-2, thereby driving the two take-up rollers 3-2 to rotate inside the two connecting seats 4, allowing the two take-up rollers 3-2 to respectively wind up and unwind the two ends of the safety net body 3. Combined with the telescopic component, the distance between the two side-mounted elastic adjustment columns 2 is adjusted, thus achieving the effect of adjusting the length of the safety net body 3. A corresponding controller is provided for the first drive motor to control its forward and reverse starting and closing.
[0026] In this embodiment, the winding rollers 3-2 rotate in opposite directions, adapting to the actions of synchronous double-sided winding or double-sided release of the mesh body 3-1. When the right winding roller 3-2 of the mesh body 3-1 rotates counterclockwise and the left winding roller 3-2 of the mesh body 3-1 rotates clockwise, the two sides of the mesh body 3-1 are synchronously wound around the two winding rollers 3-2, and the mesh body 3-1 gradually comes into a taut state, which is conducive to forming a structural form for receiving falling objects; when When the right-side take-up roller 3-2 of the net body 3-1 rotates clockwise and the left-side take-up roller 3-2 rotates counterclockwise, the two sides of the net body 3-1 are released. As each side winds out from the two take-up rollers 3-2, the net body 3-1 gradually becomes wider, forming a net-like structure that facilitates the formation of another type of structure for receiving falling objects. The different degrees of concavity of the net body 3-1 are adapted to falling objects of different shapes, weights, and heights, and can be quickly adjusted accordingly for specific situations.
[0027] Specific Implementation Method 3: This implementation method is a further limitation of Specific Implementation Method 1 or 2. In this implementation method, the two first drive motors can also be replaced with one first drive motor, so that one of the two take-up rollers 3-2 is an active take-up roller and the other is stationary, thereby realizing the process of unilaterally taking in or releasing the mesh body 3-1.
[0028] Specific Implementation Method Four: This implementation method is a further limitation of Specific Implementation Methods One, Two, or Three. Each connecting seat 4 includes a top seat 4-1, a strip support plate 4-2, and a support 4-3. The top seat 4-1 is disposed above the elastic element, and the bottom of the top seat 4-1 is connected to the elastic element. The strip support plate 4-2 is horizontally disposed between the top seat 4-1 and the lifting connecting seat 22. One end of the strip support plate 4-2 is fixedly connected to the top seat 4-1, and the other end of the strip support plate 4-2 is slidably engaged with the lifting connecting seat 22 through the support 4-3. The strip support plate 4-2 and the winding roller 3-2 are arranged in a one-to-one correspondence. One end of each winding roller 3-2 is hinged to the top seat 4-1, and the other end of each winding roller 3-2 is hinged to the support 4-3.
[0029] Specific Implementation Method 5: This implementation method is a further limitation of Specific Implementation Methods 1, 2, 3, or 4. The main support column 1 is connected to the side-mounted elastic adjustment column 2 through a telescopic assembly. The telescopic assembly includes two double-headed screws 14, four movable seats 15, and four electric telescopic rods 5. A groove 10 is machined on each of the two outer walls of the main support column 1 along its length. A double-headed screw 14 is rotatably installed inside each groove 10. Two movable seats 15 are fitted on each double-headed screw 14. Two electric telescopic rods 5 are arranged between each side-mounted elastic adjustment column 2 and the main support column 1. The electric telescopic rods 5 and the movable seats 15 are arranged in a one-to-one correspondence. One end of each electric telescopic rod 5 is hinged to its corresponding movable seat 15, and the other end of each electric telescopic rod 5 is hinged to the side-mounted elastic adjustment column 2 that is next to it.
[0030] In this embodiment, the telescopic assembly includes grooves 10 formed at both ends of the main support column 1. A double-ended screw 14 is rotatably mounted inside each of the two grooves 10, and two movable seats 15 are symmetrically mounted on the outer walls of each of the two double-ended screws 14. In actual use, two second drive motors are pre-installed at the bottom of the main support column 1. The output ends of the two second drive motors are respectively connected to the bottom ends of the two double-ended screws 14, thereby driving the two double-ended screws 14 to rotate in both directions within the corresponding grooves 10, allowing the two movable seats 15 to move towards each other and away from each other within the corresponding grooves 10.
[0031] In this embodiment, a first rotating block 16 is rotatably mounted on the end of each of the two movable seats 15 away from the double-headed screw 14. Two second rotating blocks 17 are rotatably mounted on the outer wall of each of the two side-mounted elastic adjustment columns 2 near the main support column 1. The first rotating blocks 16 and their adjacent second rotating blocks 17 are connected by an electric telescopic rod 5. When the two movable seats 15 move toward each other, they can drive the two first rotating blocks 16 to rotate within their respective movable seats 15, and drive the two second rotating blocks 17 to rotate on the outer wall of one side of the side-mounted elastic adjustment column 2. This causes the side-mounted elastic adjustment column 2 to move away from the main support column 1, increasing the distance between the side-mounted elastic adjustment column 2 and the main support column 1. As the telescopic end of the electric telescopic rod 5 continues to extend, the distance between the side-mounted elastic adjustment column 2 and the main support column 1 is further increased. Conversely, it causes the distance between the side-mounted elastic adjustment column 2 and the main support column 1 to decrease, thereby reducing the distance between the side-mounted elastic adjustment column 2 and the main support column 1, making it convenient for the side-mounted elastic adjustment column 2 to be adjusted according to actual usage requirements.
[0032] Specific Implementation Method Six: This implementation method is a further limitation of Specific Implementation Methods One, Two, Three, Four, or Five. Each elastic element includes a buffer spring 11 and a damping rod 12. A damping rod 12 is vertically installed at the top of each side-mounted elastic adjustment column 2. The damping rod 12 is a telescopic rod, and its lower end is connected to the side-mounted elastic adjustment column 2. The buffer spring 11 is fitted onto the damping rod 12, and its upper end is connected to the connecting seat 4. When an object falls from above the building onto the top of the safety net body 3, the two connecting seats 4 will also experience a certain impact force. With the cooperation of the two damping rods 12 and the buffer spring 11, the impact force can be buffered and damped to a certain extent, preventing excessive impact force between the object and the safety net body 3, which could damage the safety net body 3.
[0033] Specific Implementation Method Seven: This implementation method is a further limitation of Specific Implementation Methods One, Two, Three, Four, Five, or Six. Each connecting seat 4 is equipped with a guide plate 8 and a diagonal brace 9. The guide plate 8 is vertically arranged below the strip support plate 4-2. A diagonal brace 9 is arranged between the guide plate 8 and the strip support plate 4-2. One end of the diagonal brace 9 is connected to the guide plate 8, and the other end of the diagonal brace 9 is arranged near the middle of the strip support plate 4-2. Each guide plate 8 is equipped with a guide block 18 on the side near the side-mounted elastic adjustment column 2. Each side-mounted elastic adjustment column 2 is provided with a guide groove 13 on the outer wall of the side near the guide plate 8, which moves up and down with the guide block 18.
[0034] In this embodiment, guide plates 8 and diagonal braces 9 are installed at the bottom ends of both connecting seats 4. The ends of the two guide plates 8 and diagonal braces 9 away from the connecting seats 4 are connected. Guide blocks 18 are installed on the side of the two guide plates 8 near the side-mounted elastic adjustment column 2. Guide grooves 13 for the guide blocks 18 to move up and down are opened on the outer wall of the side of the two side-mounted elastic adjustment columns 2 near the guide plates 8. The guide plates 8 and guide blocks 18 can limit the movement trajectory of the damping rod 12 and the buffer spring 11, so that they always move in a straight line. The diagonal braces 9 can improve the support strength of the connecting seats 4, thereby improving the strength of the safety net body 3.
[0035] Specific Implementation Method Eight: This implementation method is a further limitation of Specific Implementation Methods One, Two, Three, Four, Five, Six, or Seven. The lifting connecting seat 22 includes a support plate. The outer wall of the support plate facing the side-mounted elastic adjustment column 2 is machined with a groove 19. The length direction of the groove 19 is in the same direction as the length direction of the support plate. The transverse cross-sectional shape of the groove 19 is T-shaped. Multiple elastic protrusions 21 are respectively provided on the inner walls of the two sides of the groove 19. A slider 20 is slidably fitted inside the groove 19. The connecting seat 4 is connected to the slider 20. When the safety net body 3 is hit by a falling object, the connecting seat 4 moves downward along the length direction of the groove 19 through the slider 20.
[0036] In this embodiment, the lifting connecting seat 22 cooperates with the elastic element to realize the multi-position coordinated lifting movement of the connecting seat body 4. When the falling object hits the safety net body 3, the lifting connecting seat 22 and the elastic element cooperate with the safety net body 3 to complete multiple reciprocating lifting movements after the falling object hits.
[0037] In this embodiment, the lifting connecting seat 22 is a connector that can be detachably connected to the exterior wall of the building. The lifting connecting seats 22 are arranged vertically side by side. A sliding groove 19 is machined on one outer wall of the lifting connecting seat 22. The sliding groove 19 is a T-shaped groove, and multiple elastic protrusions 21 are provided in the T-shaped groove. The elastic protrusions 21 are hemispherical and made of soft rubber material, which facilitates installation and disassembly. The other end of each of the two connecting seats 4 is provided with a slider 20. The thickness of the slider 20 is the same as the thickness of the connecting seat 4. The connecting seat 4 is raised and lowered by the slider 20 cooperating with the sliding groove 19. The connecting seat 22 slides back and forth along its length. The distance between any two adjacent elastic protrusions 21 is one-fifth of that between the slider 20. During the sliding of the slider 20 in the slide groove 19, the elastic protrusions 21 can reduce the rapid movement of the slider 20 in the slide groove 19, thus providing multi-position buffering and delaying the impact of the connecting seat 4 after being hit by a falling object. The two ends of the lifting connecting seat 22 are respectively machined with round holes along its plate thickness direction. By using bolts to cooperate with the round holes, the lifting connecting seat 22 can be installed on the exterior wall of the public building. It is easy to disassemble and quick to install.
[0038] Specific Implementation Method Nine: This implementation method is a further limitation of Specific Implementation Methods One, Two, Three, Four, Five, Six, Seven, or Eight. A base 6 is installed at the bottom end of both the main support column 1 and the two side-mounted elastic adjustment columns 2. Mounting holes are provided at the four corner positions of the base 6. After determining the positions of the two side-mounted elastic adjustment columns 2 and the main support column 1, the base 6 is installed on the ground in the designated area using multiple bolts or other fasteners passing through the mounting holes, thus fixing the safety net body 3 in its operational state.
[0039] This utility model can be used for emergency assembly and rescue, as well as for long-term installation and protection on building exterior walls, to meet different safety requirements for different types of falling objects. For quick installation, simply attach or tighten the lifting connecting seat 22 against the building exterior wall. Adjust the tightness or concavity of the safety net body 3 according to the specific circumstances of the falling object, thereby achieving rapid protection and catching of the falling object.
[0040] When it is necessary to achieve durable use on the exterior wall of a building, the main support column 1 and the two side-mounted elastic adjustment columns 2 are fixedly installed on the ground, and the two lifting connecting seats 22 are detachably connected to the exterior wall of the building.
[0041] In this utility model, when it is necessary to install a safety net body 3 under a building under construction or a public building already in use to prevent objects from falling from above and causing safety hazards, the two winding rollers 3-2 can be controlled to rotate first, so that the length of the safety net body 3 can be extended. Then, the two double-headed screws 14 are controlled to rotate, driving the two moving seats 15 to move in the same direction. The telescopic ends of multiple electric telescopic rods 5 are extended to adjust the distance between the two side elastic adjustment columns 2 and the main support column 1, so that the distance between the two side elastic adjustment columns 2 corresponds to the length of the safety net body 3.
[0042] The specific installation process is as follows: Figure 1As shown, two bolts are first passed through the round holes on the two lifting connecting seats 22 and fixed to the exterior wall surface of the building in the designated area. The two connecting seats 4 are installed on the two lifting connecting seats 22 through the cooperation between the slider 20 and the slide groove 19. Then, multiple bolts or other fasteners are passed through the mounting holes of multiple bases 6, so that multiple bases 6 can be installed on the ground in the designated area. This allows the safety net body 3 located below the exterior wall of the building under construction or the public building already in use to block falling objects and avoid danger to passersby and children playing below. At the same time, when the falling object contacts the safety net body 3, the two connecting seats 4 slide along the length of the lifting connecting seat 22 using the slider 20 and the slide groove 19. The elastic protrusion 21 slows down the rapid sliding of the slider 20 in the slide groove 19 and prevents the falling object from bouncing.
[0043] When the safety net body 3 is used in the external environment, in order to prevent the safety net body 3 from being blown away in windy weather and to maintain the stability of the safety net body 3 during use, the two winding rollers 3-2 can be reversed to drive the two ends of the safety net body 3 to be wound on the surface of the two winding rollers 3-2, so that the safety net body 3 is in a taut state and the stability of the safety net body 3 in windy weather is improved.
[0044] Since the safety net body 3 is used in the external environment, it is inevitable that fallen leaves, plastic bags and other debris will accumulate on its top. In order to maintain the aesthetics of the safety net body 3 during use, the staff needs to clean the debris accumulated on the top of the safety net body 3 regularly. At this time, one of the winding rollers 3-2 can be controlled to rotate, which will drive one end of the safety net body 3 to continue to unfold and move downward. The debris on the top of the safety net body 3 will slide to the lower end, making it convenient for the staff to clean it. There is no need for the staff to climb up to the level of the safety net body 3 to clean it, thus improving the efficiency of debris cleaning.
[0045] Furthermore, in the event of an accident such as a fire inside the building, in order not to affect the firefighters' control of the fire, the two winding rollers 3-2 can be rotated simultaneously, so that the two ends of the safety net body 3 continue to unfold and move downwards to contact the ground. With the help of other fixing tools, the safety net body 3 that has fallen to the ground can be fixed, so that fire trucks can easily extinguish the fire inside the building. This ensures that the installation of the safety net body 3 will not affect the rapid extinguishing of the building fire.
[0046] When a falling object or a heavy object falls onto the top of the safety net body 3, the two connecting seats 4 will also be subjected to a certain impact force. With the cooperation of the two damping rods 12 and the buffer spring 11, the impact force can be buffered and damped to a certain extent. At the same time, the two connecting seats 4 slide along the length of the lifting connecting seat 22 through the cooperation between the slider 20 and the slide groove 19. When the slider 20 moves in the slide groove 19, the elastic protrusion 21 can slow down the rapid descent of the connecting seats 4 driven by the slider 20, so as to avoid the problem of excessive impact force between the object and the safety net body 3, which could damage the safety net body 3.
[0047] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
