Description

Technical Field

[0001] The present invention belongs to the technical field of protective nets, and particularly relates to a retractable safety protective net for high-rise building construction and a using method thereof. Background Art

[0002] In large-scale high-rise building projects, the phenomenon of frequent cross-operation is relatively common. In such construction sites, many workers need to work simultaneously in different spaces. This cross-situation increases safety hazards. To effectively prevent the risks brought by cross-operation, a single-layer horizontal safety protective net is generally set every four floors on the building. The setting of these protective nets can effectively avoid the danger of workers falling from heights, protect their lives, and at the same time can effectively prevent falling objects from hurting other workers or pedestrians below and protect their safety.

[0003] However, when installing the existing construction safety protective net, the steel erectors need to climb to a high altitude position dozens of meters above the ground outdoors and work suspended in the air. This working method has certain risks and challenges. The steel erectors working suspended in the air at high altitudes are inherently highly dangerous. Once an accident occurs, the consequences may be very serious. Moreover, the buffer performance of the existing construction safety protective net is poor. When the dropped object has too high a dropping height or too large a weight, the excessive impact force will cause the net ropes on the protective net to break, damage the protective net, and cannot hold the falling staff or objects well.

[0004] To solve the above problems, a retractable safety protective net for high-rise building construction and a using method thereof are proposed in this application. Summary of the Invention

[0020] As a preferred embodiment of the foldable high-rise building construction safety protection net of the present invention, the size of the positioning card matches the size of the positioning column.

[0021] A method for using a retractable high-rise building construction safety protection net comprises the following steps:

[0022] S1. When in use, first move the indoor support frame to the indoor installation position, then turn on the driving motor on the support fixing mechanism, and drive the screw rod to rotate through the driving motor. When the screw rod rotates, the lifting plate, the top rod, and the top plate can be driven to rise through the driving screw sleeve. When the top plate rises to a certain height and contacts the ceiling, the installation and fixation of the indoor support frame can be completed;

[0023] After the indoor support frame is fixed, control the hydraulic telescopic arm to expand to both sides through the swing arm expansion and retraction mechanism. After the hydraulic telescopic arm expands to both sides, fix and install the protective net retracting and deploying module at the end of the hydraulic telescopic arm through the buffer mechanism. After the protective net retracting and deploying module is installed, then control the hydraulic telescopic arm to extend. During the process of the hydraulic telescopic arm extending to both sides, drive the protective net retracting and deploying module to expand outward at the same time, and automatically complete the laying of the protective net;

[0024] After the protective net is laid, it is in a straightened state. When a staff member or an object falls, the protective net can catch the staff member or the falling object, and the buffer mechanism can buffer and protect the falling staff member or object. When the height or weight of the falling staff member or object is too high or too large, and the buffer mechanism is compressed to a certain extent, the positioning mechanism will be triggered. The pulley assembly on the positioning mechanism cooperates with the extrusion plate to make the linkage plate move to one side. During the process of the linkage plate moving to one side, the positioning latch will be pulled through the slide rod. At this time, the positioning latch is separated from the positioning column. After the positioning latch is separated from the positioning column, the first guiding roller on the protective net release mechanism will quickly move downward for reset under the action of the return spring, and a certain length of the protective net can be quickly released. After a certain length of the protective net is released, it is in a U-shaped relaxed state, which can not only better catch the falling staff member or object, but also relieve the net ropes on the protective net. The compressed buffer mechanism can be reset when the protective net is released, and the reset buffer mechanism can buffer and protect the falling staff member or object again.

[0025] Compared with the prior art, the beneficial effects of the present invention are:

[0026] By setting the support and fixing mechanism, the indoor support frame can be quickly installed and fixed indoors through the support and fixing mechanism. After the indoor support frame is fixed, control the hydraulic telescopic arm to expand to both sides through the swing arm expansion and retraction mechanism. After the hydraulic telescopic arm expands to both sides, fix and install the protective net retracting and deploying module at the end of the hydraulic telescopic arm through the buffer mechanism. After the protective net retracting and deploying module is installed, then control the hydraulic telescopic arm to extend. During the process of the hydraulic telescopic arm extending to both sides, the protective net retracting and deploying module can be driven to expand outward at the same time, and the laying of the protective net can be automatically completed. The construction safety protective net can be installed and fixed indoors, and it is not necessary for a scaffolder to climb to a high altitude of dozens of meters above the ground outdoors to work suspended in the air, with high safety;

[0027] By setting up a protective net retracting and deploying module, the protective net retracting and deploying module can store the used protective net, which is convenient for carrying and handling. By setting up a swing arm deploying and retracting mechanism, the hydraulic telescopic arms on both sides can be deployed or folded and stored through the swing arm deploying and retracting mechanism, which can avoid the influence of the narrow width of the room window on the extension and installation of the hydraulic telescopic arms. By setting up a buffer mechanism, the falling staff or objects can be buffered and protected through the buffer mechanism;

[0028] When the height or weight of the falling staff or object is too high or too large, and the buffer mechanism is compressed to a certain extent, the positioning mechanism will be triggered. The pulley assembly on the positioning mechanism cooperates with the extrusion plate to make the linkage plate move to one side. During the process of the linkage plate moving to one side, the positioning card will be pulled by the sliding rod. At this time, the positioning card is separated from the positioning column. After the positioning card is separated from the positioning column, the first guiding roller on the protective net release mechanism will quickly move downward for reset under the action of the reset spring, and a certain length of the protective net can be quickly released. The released protective net is in a U-shaped relaxed state, which can not only better catch the falling staff or object, but also relieve the net ropes on the protective net. The compressed buffer mechanism can be reset when the protective net is released, and the reset buffer mechanism can buffer and protect the falling staff or object again, which can avoid the net ropes on the protective net being broken due to excessive impact force and can better catch the falling staff or object.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0051] An embodiment is as follows Figures 1-9 As shown, a retractable safety protection net for high-rise building construction includes an indoor support frame 1 and a first guiding chute 2 opened on the indoor support frame 1;

The top rods 307 are symmetrically and fixedly arranged on the top of the lifting plate member 305. The top plate 308 is fixedly arranged at the top of the top rods 307. By driving the driving motor 302, the lead screw 303 can be rotated clockwise or counterclockwise. When the lead screw 303 rotates clockwise or counterclockwise, the lifting plate member 305, the top rod 307, and the top plate 308 can be driven to lift. By driving the lifting plate member 305, the top rod 307, and the top plate 308 to rise, when the top plate 308 rises to a certain height and abuts against the ceiling, the indoor support frame 1 can be installed and fixed;

[0054] One side of the indoor support frame 1 is fixedly connected with a swing arm unfolding and retracting mechanism 4 through bolts. The swing arm unfolding and retracting mechanism 4 includes an extension plate member 401 fixedly installed on one side of the indoor support frame 1 through bolts, a rotating motor 402, a gear member A 403, and a gear member B 404;

[0055] The extension plate member 401 is fixedly installed on one side of the indoor support frame 1 by bolts. The rotating motor 402 is fixedly installed at the bottom of one end of the extension plate member 401. Both the gear member A 403 and the gear member B 404 are rotatably installed in the groove at one end of the extension plate member 401 through rotating shafts, and the gear member A 403 is fixedly connected to the output shaft of the rotating motor 402. When installed and used, the extension plate member 401 extends from the window to the outside. Before installation, the hydraulic telescopic arm 5 is in a folded state. After the extension plate member 401 extends from the window to the outside and the installation is completed, the rotating motor 402 on the swing arm unfolding and retracting mechanism 4 is turned on. The rotating motor 402 on the swing arm unfolding and retracting mechanism 4 can drive the gear member A 403 to rotate. When the gear member A 403 rotates, it can meshingly drive the gear member B 404 to rotate. Through the gear member A 403 and the gear member B 404, the hydraulic telescopic arms 5 on both sides can be unfolded or folded and stored, which can avoid the influence of the narrow width of the room window on the extension and installation of the hydraulic telescopic arm 5;

[0056] Both the outer sides of the gear member A 403 and the gear member B 404 are fixedly connected with hydraulic telescopic arms 5 through connecting members. One end of each of the two groups of hydraulic telescopic arms 5 is fixedly connected with a buffer mechanism 6 through bolts. The buffer mechanism 6 includes a support plate member 601 fixedly installed on the outer side of one end of the hydraulic telescopic arm 5 by bolts, a T-shaped pin rod 602, a buffer spring 603, and a damper 604;

[0057] The support plate member 601 is fixedly installed on the outer side of one end of the hydraulic telescopic arm 5 by bolts. The T-shaped pin rod 602 is slidably inserted through the support plate member 601. The buffer spring 603 is sleeved on the outer side of the T-shaped pin rod 602.

Through the mutual cooperation among the support plate member 601, the T-shaped pin rod 602, the buffer spring 603, and the damper 604 on the buffer mechanism 6, the falling staff or objects can be buffered and protected;

[0058] The top end of the T-shaped pin rod 602 is fixedly connected with a protective net retracting and deploying module 7. The protective net retracting and deploying module 7 includes a first rectangular housing 701 and a second rectangular housing 702 fixedly connected to the top end of the T-shaped pin rod 602, a winding motor 703 fixedly installed on the front side of the first rectangular housing 701, a protective net winding roller 704, and a protective net connecting column 705;

The end of the output shaft of the winding motor 703 is fixedly connected to the protective net winding roller 704. The protective net winding roller 704 and the protective net connecting column 705 are respectively rotatably installed inside the first rectangular housing 701 and the second rectangular housing 702 through bearings. During the process of the hydraulic telescopic arm 5 extending to both sides, it drives the protective net winding and unwinding module 7 to expand outward at the same time. When the protective net winding and unwinding module 7 expands outward, the winding motor 703 is controlled to rotate in the reverse direction to unwind the protective net 8, and the laying of the protective net 8 can be automatically completed. When it is to be removed after use, the winding motor 703 is controlled to rotate in the forward direction to store the used protective net 8;

[0060] A protective net 8 is provided between the protective net winding roller 704 and the protective net connecting column 705. Protective net release mechanisms 9 are provided inside both the first rectangular housing 701 and the second rectangular housing 702. The protective net release mechanism 9 includes rectangular notches 901 symmetrically opened on the outer sides of the first rectangular housing 701 and the second rectangular housing 702, second guide chutes 902, return springs 903, lifting blocks 904, second sliders 905, positioning columns 906, first guide rollers 907, and second guide rollers 908;

[0061] The rectangular notches 901 are symmetrically opened on the outer sides of the first rectangular housing 701 and the second rectangular housing 702. The second guide chutes 902 are opened on both sides of the inner cavity of the rectangular notches 901. The return springs 903 are fixedly connected to the top of the inner cavity of the rectangular notches 901. The bottom ends of the return springs 903 are fixedly connected to the lifting blocks 904. The positioning columns 906 and the first guide rollers 907 are respectively arranged on the front and rear sides of the lifting blocks 904. The second guide rollers 908 are respectively rotatably installed inside the first rectangular housing 701 and the second rectangular housing 702. The second sliders 905 are fixedly arranged on both sides of the lifting blocks 904. The lifting blocks 904 are slidably installed in the rectangular notches 901 through the second sliders 905 and the second guide chutes 902;

[0062] Positioning mechanisms 10 are symmetrically provided on both sides of the first rectangular housing 701 and both sides of the second rectangular housing 702. The positioning mechanism 10 includes connecting plate members 1001 fixedly installed on both sides of the first rectangular housing 701 and both sides of the second rectangular housing 702, slide rods 1002, positioning clips 1003, linkage plate members 1004, spring members 1005, extrusion plates 1006, and pulley assemblies 1007 fixedly connected to the outer side of the support plate member 601 through support rods;

[0063] The connecting plate member 1001 is fixedly installed on both sides of the first rectangular housing 701 and both sides of the second rectangular housing 702. The sliding rod 1002 is slidably inserted through the connecting plate member 1001. The positioning card member 1003 and the linkage plate member 1004 are respectively fixedly arranged at both ends of the sliding rod 1002. The spring member 1005 is sleeved outside the sliding rod 1002. The extrusion plate 1006 is fixedly arranged on one side of the linkage plate member 1004. The pulley assembly 1007 is fixedly connected to the outside of the support plate member 601 through a support rod. The size of the positioning card member 1003 matches the size of the positioning post 906. When the height or weight of a worker or an object during falling is too high or too large, and the buffer mechanism 6 is compressed to a certain extent, the positioning mechanism 10 will be triggered. The cooperation between the pulley assembly 1007 and the extrusion plate 1006 on the positioning mechanism 10 will cause the linkage plate member 1004 to move to one side. During the process of the linkage plate member 1004 moving to one side, the positioning card member 1003 will be pulled by the sliding rod 1002. At this time, the positioning card member 1003 is separated from the positioning post 906. After the positioning card member 1003 is separated from the positioning post 906, the first guiding roller 907 on the protective net release mechanism 9 will quickly move downward for reset under the action of the reset spring 903, and a certain length of the protective net 8 can be quickly released. After a certain length of the protective net 8 is released, it is in a U-shaped relaxed state, which can not only better catch the falling worker or object, but also relieve the net ropes on the protective net 8. The compressed buffer mechanism 6 can be reset when the protective net 8 is released, and the reset buffer mechanism 6 can buffer and protect the falling worker or object again.

[0064] A usage method of a retractable safety protection net for high-rise building construction includes the following steps:

[0065] S1. During use, first move the indoor support frame 1 to the indoor installation position, and then turn on the drive motor 302 on the support fixing mechanism 3. The drive motor 302 drives the lead screw 303 to rotate. When the lead screw 303 rotates, it can drive the lifting plate member 305, the ejector rod 307, and the top plate 308 to rise through the drive nut 304. When the top plate 308 rises to a certain height and abuts against the ceiling, the installation and fixation of the indoor support frame 1 can be completed.

[0066] S2. After the indoor support frame 1 is fixed, control the hydraulic telescopic arm 5 to expand to both sides through the swing arm expansion and retraction mechanism 4. After the hydraulic telescopic arm 5 expands to both sides, fix the protective net retracting and releasing module 7 at the end of the hydraulic telescopic arm 5 through the buffer mechanism 6. After the protective net retracting and releasing module 7 is installed, then control the hydraulic telescopic arm 5 to extend. During the process of the hydraulic telescopic arm 5 extending to both sides, it drives the protective net retracting and releasing module 7 to expand outward at the same time, and automatically completes the laying of the protective net 8.

[0067] S3. After the protective net 8 is laid, it is in a straightened state. When a staff member or an object falls, the protective net 8 can catch the staff member or the falling object, and the buffer mechanism 6 can buffer and protect the falling staff member or object. When the height or weight of the falling staff member or object is too high or too large, and the buffer mechanism 6 is compressed to a certain extent, the positioning mechanism 10 will be triggered. The pulley assembly 1007 on the positioning mechanism 10 cooperates with the pressing plate 1006 to make the linkage plate 1004 move to one side. During the process of the linkage plate 1004 moving to one side, the positioning card 1003 will be pulled by the sliding rod 1002. At this time, the positioning card 1003 is separated from the positioning column 906. After the positioning card 1003 is separated from the positioning column 906, the first guiding roller 907 on the protective net release mechanism 9 will quickly move downward for reset under the action of the return spring 903, and a certain length of the protective net 8 can be quickly released. After a certain length of the protective net 8 is released, it is in a U-shaped relaxed state, which can not only better catch the falling staff member or object, but also relieve the net ropes on the protective net 8. The compressed buffer mechanism 6 can be reset when the protective net 8 is released, and the reset buffer mechanism 6 can buffer and protect the falling staff member or object again.

[0068] In this implementation scheme: during use, first move the indoor support frame 1 to the indoor installation position, then turn on the drive motor 302 on the support and fixation mechanism 3, and drive the screw rod 303 to rotate through the drive motor 302. When the screw rod 303 rotates, it can drive the lifting plate 305, the top rod 307, and the top plate 308 to rise through the drive sleeve 304. When the top plate 308 rises to a certain height and touches the ceiling, the installation and fixation of the indoor support frame 1 can be completed. After the indoor support frame 1 is fixed, control the hydraulic telescopic arm 5 to expand to both sides through the swing arm expansion and retraction mechanism 4. After the hydraulic telescopic arm 5 expands to both sides, fix the protective net retracting and releasing module 7 at the end of the hydraulic telescopic arm 5 through the buffer mechanism 6. After the protective net retracting and releasing module 7 is installed, then control the hydraulic telescopic arm 5 to extend. During the process of the hydraulic telescopic arm 5 extending to both sides, it drives the protective net retracting and releasing module 7 to expand outward at the same time, and automatically complete the laying of the protective net 8;

[0069] After the protective net 8 is laid, it is in a straightened state. When a staff member or an object falls, the protective net 8 can catch the staff member or the falling object, and the buffer mechanism 6 can buffer and protect the falling staff member or object. When the height or weight of the falling staff member or object is too high or too large, when the buffer mechanism 6 is compressed to a certain extent, the positioning mechanism 10 will be triggered. The pulley assembly 1007 on the positioning mechanism 10 cooperates with the extrusion plate 1006 to make the linkage plate 1004 move to one side. During the process of the linkage plate 1004 moving to one side, the positioning card 1003 will be pulled by the slide rod 1002. At this time, the positioning card 1003 is separated from the positioning column 906. After the positioning card 1003 is separated from the positioning column 906, the first guide roller 907 on the protective net release mechanism 9 will quickly move downward for reset under the action of the return spring 903, and a certain length of the protective net 8 can be quickly released. After a certain length of the protective net 8 is released, it is in a U-shaped relaxed state, which can not only better catch the falling staff member or object, but also relieve the net ropes on the protective net 8. The compressed buffer mechanism 6 can be reset when the protective net 8 is released, and the reset buffer mechanism 6 can buffer and protect the falling staff member or object again.

[0070] It should be noted that: the size of the positioning card 1003 matches the size of the positioning column 906. Under normal conditions, the positioning card 1003 is stuck outside the positioning column 906.

[0071] Finally, it should be noted that: the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.

10. A method for using a retractable high-rise building construction safety protection net according to any one of claims 1-9 includes the following steps: S1. During use, first carry the indoor support frame (1) to the indoor installation position, and then turn on the drive motor (302) on the support and fixation mechanism (3). Drive the screw rod (303) to rotate through the drive motor (302). When the screw rod (303) rotates, it can drive the lifting plate member (305), the ejector rod (307), and the top plate (308) to rise through the drive nut (304). When the top plate (308) rises to a certain height and abuts against the ceiling, the installation and fixation of the indoor support frame (1) can be completed. S2. After the indoor support frame (1) is fixed, control the hydraulic telescopic arm (5) to expand to both sides through the swing arm expansion and retraction mechanism (4). After the hydraulic telescopic arm (5) expands to both sides, fix the protection net retraction and release module (7) at the end of the hydraulic telescopic arm (5) through the buffer mechanism (6). After the protection net retraction and release module (7) is installed, then control the hydraulic telescopic arm (5) to extend. During the process of the hydraulic telescopic arm (5) extending to both sides, it drives the protection net retraction and release module (7) to expand outward at the same time, and automatically completes the laying of the protection net (8). S3. After the protective net (8) is laid, it is in a straightened state. When a staff member or an object falls, the protective net (8) can catch the staff member or the falling object, and the buffer mechanism (6) can buffer and protect the falling staff member or object. When the height or weight of the falling staff member or object is too high or too large, and the buffer mechanism (6) is compressed to a certain extent, the positioning mechanism (10) will be triggered. The pulley assembly (1007) on the positioning mechanism (10) cooperates with the extrusion plate (1006) to make the linkage plate member (1004) move to one side. During the process of the linkage plate member (1004) moving to one side, the positioning clip (1003) will be pulled by the slide rod (1002). At this time, the positioning clip (1003) is separated from the positioning column (906).
