Description

Technical Field

[0001] This invention relates to the field of construction safety equipment technology, specifically to a protective net for supporting and stabilizing scaffolding and scaffolding. Background Technology

[0002] Scaffolding refers to various supporting structures erected on construction sites to facilitate worker operations and vertical and horizontal transportation. It's a common term in the construction industry, referring to structures used on construction sites for exterior walls, interior decoration, or areas with high ceilings where direct construction is impossible. Primarily, it's for workers to move up and down, for external safety netting, and for installing components at heights. In short, it's setting up a frame. Scaffolding materials typically include bamboo, wood, steel pipes, or composite materials. Existing scaffolding, after assembly, needs to be surrounded by safety netting on the outside to ensure safety during construction.

[0003] However, existing scaffolding safety nets have certain drawbacks when assembled with scaffolding. For example, when installing existing scaffolding safety nets on one side of the scaffolding, workers need to insert bolts into multiple ear plate holes on the side of the safety net, and then fix the bolts to one side of the scaffolding to complete the installation. Since most of the external scaffolding safety nets are large in area, workers need to use bolts to fix the safety net panels one by one during installation, which is cumbersome and reduces the overall assembly efficiency. Overall, it has certain limitations in actual use. Summary of the Invention

[0004] The purpose of this invention is to provide a stable and supportive scaffolding safety net and scaffolding, in order to solve the problems mentioned in the background art. Existing scaffolding safety nets require workers to insert bolts into multiple ear plate holes on the side of the safety net before fixing it to one side of the scaffolding. Since most building scaffolding safety nets are large, workers need to use bolts to fix each net panel individually, making the installation cumbersome, reducing overall assembly efficiency, and limiting its practical application.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a protective net for supporting and stabilizing scaffolding, comprising a main frame, wherein the main frame is arranged longitudinally at equal intervals, and a metal mesh is installed inside the main frame. A locking block is symmetrically fixed to the outside of one side of the main frame. Hollow columns are symmetrically arranged longitudinally on the side of the main frame near the locking block. A limiting groove is longitudinally provided through the middle of the outer surface of the hollow column near the locking block. A second limiting groove is provided through the bottom end of the hollow column near the locking block. A splicing mechanism is provided on the outer sides of both edges of the main frame. An installation frame is bolted to the top of two hollow columns, and an electric hoist is installed at the middle of the top of the installation frame.

[0006] Preferably, the card block is T-shaped when viewed from above, the width of the second limiting groove is greater than the width of the first limiting groove and the card block, and the height of the second limiting groove is greater than the height of the card block, so that the card block can be completely placed inside the second limiting groove, and the side of the card block near the cavity column is provided with a positioning groove.

[0007] The above technical solution enables the main frame to be inserted into the bottom of the cavity column by passing the locking block on one side through the limiting groove 2 during use. This facilitates the locking block to be engaged and slidably installed inside the top limiting groove 1, thereby limiting the main frame on the outside.

[0008] Preferably, the splicing mechanism includes a suspension block, a mounting groove, a stop block, a rotating shaft, an extension block, a return spring, and a positioning bolt. The function of the splicing mechanism is to longitudinally splice and fix the two main frames together. The suspension block is fixedly installed on the outside of the top side of the main frame, and the suspension block is generally n-shaped.

[0009] The above technical solution enables the overall system to be used by longitudinally splicing multiple main frames to form a large protective net through the splicing mechanism. Then, the electric hoist at the top is used to pull the spliced ​​main frame up along the limit groove to complete the assembly, providing full coverage protection for one side of the scaffold. The overall assembly efficiency is high and the use effect is good.

[0010] Preferably, the mounting groove is embedded in the main frame near the bottom of the suspension block. A rotating shaft is rotatably mounted inside one edge of the mounting groove. A stop block is fixed on one side of the rotating shaft, and the width of the stop block is less than the distance between the inner walls of the suspension block. One end of the rotating shaft is rotatably mounted through the outside of one side of the main frame. An extension block is fixed on the side of the rotating shaft away from the stop block. A return spring is fixed on the top side of the extension block away from the top of the rotating shaft, and the top of the return spring is fixedly mounted on the outside of one side of the main frame.

[0011] By adopting the above technical solution, when the two main frames are assembled, the suspension block at the top of the bottom main frame is aligned with the mounting groove at the bottom of the top main frame and then pressed against it. This causes the suspension block to press against the stop block inside the mounting groove, which rotates. After rotating to a certain position, the suspension block reaches the top of the mounting groove, causing the stop block to lose its contact. With the help of the return spring on one side, the suspension block returns to the horizontal position. At the same time, the contact of the bottom positioning bolt keeps the suspension block at the top of the stop block, so that the two main frames can automatically lock together and not detach, ensuring stability. The overall assembly is convenient and not easy to fall off.

[0012] Preferably, a positioning bolt is installed through the inside of the main frame near the bottom of the block, and the top of the positioning bolt is in contact with the outer surface of the bottom of the block to restrict the block.

[0013] The above technical solution makes it easy to separate the two main frames when using the whole system. Simply rotate the positioning bolt on one side to disengage it from the bottom of the stop block, so that the bottom of the stop block loses its contact and can rotate downwards. This allows the top-limited suspension block to be easily pulled out, thus separating the two main frames and making the whole system easy to assemble and disassemble.

[0014] Preferably, a positioning mechanism is provided inside one side of the cavity column. The positioning mechanism includes a slide rod, an auxiliary block, a guide groove, a stop rod, an auxiliary frame, a stop block, and a jack. The slide rod is longitudinally slidably installed on the inner wall of one side of the cavity column through the support block. An auxiliary block is fixedly inserted through one side of the slide rod at equal intervals. A guide groove is provided inside each of the auxiliary blocks. A jack is installed on the outside of one side of the bottom of the cavity column, and the top output end of the jack is fixedly installed to the bottom end of the slide rod.

[0015] The above technical solution enables the multiple main frame sections to be repositioned after being stretched during use, through the setting of the positioning mechanism, so as to ensure the stability of the protective net formed by the whole and ensure the safety of the whole assembly.

[0016] Preferably, the guide groove is inclined, and the cavity column is provided with a horizontally arranged abutment rod on the side near the auxiliary block. The abutment rod is provided with an auxiliary frame that slides through it on the side near the locking block. One end of the auxiliary frame is fixedly installed on the inner wall of one side of the cavity column. The abutment rod is L-shaped when viewed from above, and the shorter end of the abutment rod is slidably engaged with the inside of one side of the guide groove.

[0017] By adopting the above technical solution, when the multiple spliced ​​main frames are pulled up to the top, the jacks on both sides are rotated to raise the top sliding rod. Then, with the guidance of the guide groove, the abutment rod on one side drives the abutment block to extend and abut into the positioning grooves on both sides of the main frame, thereby performing secondary positioning of each main frame and ensuring that it can be stably suspended and installed on the outside of the scaffold.

[0018] Preferably, an abutment block is fixedly installed on the side of the abutment rod near the locking block, and the surface area of ​​the abutment block is smaller than the surface area of ​​the positioning groove, so that the abutment block can abut and engage with the inside of the positioning groove to restrict the main frame;

[0019] By adopting the above technical solution, when the whole is in use, the contact block abuts against the inside of the positioning groove on one side of the card block, thereby positioning one side of the main frame, ensuring its installation stability and ensuring the overall assembly effect.

[0020] To achieve the above objectives, the present invention also provides a scaffold, including a frame board, uprights, triangular support frames, and a scaffold protective net with stable support as described above. The uprights are symmetrically arranged, and triangular support frames are fixed to the outer side of one side of the two uprights at equal intervals by bolts. Frame boards are installed and fixed between the two triangular support frames on the outer side of one side of the two uprights. The two hollow columns are installed on the outer side of the triangular support frames on the side away from the main frame by bolts.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. In use, this device, by fixing the hollow column and the upright column, allows a locking block on one side of the main frame to be placed inside the hollow column through the limiting groove two. Then, the electric hoist at the top is used to lift and raise the main frame, causing the locking blocks on both sides to engage inside the limiting groove one. The T-shaped design of the locking blocks ensures the stability of the main frame during lifting and movement, providing a certain guiding and limiting function. After one main frame is lifted to a certain height, the splicing mechanism allows another main frame to be longitudinally spliced ​​with the main frame lifted at the top. Following the above steps, multiple main frames can be spliced ​​and raised in sequence to cover the outer sides of the two hollow columns, thus forming a complete protective net and completing the overall installation. In actual installation, workers only need to assemble the main frames in an orderly manner on the ground and then use the electric hoist at the top to lift and cover them. There is no need to use bolts to position and install each protective net panel individually, making the overall assembly simpler, more convenient, safer, and more efficient.

[0023] 2. In use, this device, through the installation and cooperation of the internal mounting groove, stop block, rotating shaft, extension block and return spring of the splicing mechanism, allows the two main frames to be spliced ​​by simply inserting the n-shaped suspension block at the top of one main frame into the mounting groove at the bottom of the other main frame. During the contact process, the suspension block will rotate against the stop block. When it has been inserted to a certain depth, one side of the stop block will disengage from the other side of the suspension block. Then, with the rebound of the outer return spring, the stop block will rotate back to the initial horizontal position, causing the stop block to flip into the middle position of the n-shaped suspension block, thereby limiting the suspension block to the top of the stop block. At the same time, with the bottom positioning bolt limiting the contact at the bottom of the stop block, the suspension block will not slip off the top of the stop block, thus completing the self-locking splicing. The overall operation is convenient and highly stable. In addition, during disassembly, simply rotate the positioning bolt on one side to disengage from the bottom of the stop block, so that the bottom of the stop block loses contact, allowing the stop block to rotate downwards, thus easily pulling out the top-limited suspension block, thereby separating the two main frames. The overall assembly and disassembly are convenient.

[0024] 3. When using this device, after the multiple spliced ​​main frames are stretched to the top by the electric hoist to complete the installation and coverage of the entire protective net, the jacks on both sides can be rotated to raise the output ends of the jacks, thereby driving the top sliding rods and auxiliary blocks to rise simultaneously. This, combined with the sliding engagement of multiple auxiliary frames and contact rods, and the inclined design of the guide grooves inside the auxiliary blocks and the sliding engagement of one end of the contact rod inside one side of the guide groove, allows multiple auxiliary blocks to move simultaneously on one side as they rise. This causes the contact blocks to abut into the positioning grooves on the corresponding side of the locking blocks, achieving secondary contact and limiting of the multiple main frames. This ensures the stability of the main frame support after being stretched, guarantees overall assembly stability, ensures overall safety during use, and is easy to operate.

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0037] Please see Figure 1-10 This invention provides a technical solution: a protective net for supporting and stabilizing scaffolding, including a main frame 1, the main frame 1 being arranged longitudinally at equal intervals, a metal mesh 2 installed inside the main frame 1, a clamping block 3 symmetrically fixed on one side of the main frame 1, hollow columns 7 symmetrically arranged longitudinally on the side of the main frame 1 near the clamping block 3, a limiting groove 9 longitudinally penetrating the middle position of the outer surface of the hollow column 7 near the clamping block 3, a limiting groove 10 penetrating the bottom end of the hollow column 7 near the clamping block 3, splicing mechanisms 4 provided on the outer sides of both edges of the main frame 1, and a mounting bracket 12 bolted to the top of the two hollow columns 7, and an electric hoist 13 installed at the middle position of the top of the mounting bracket 12.

[0038] A type of scaffolding includes a frame board 6, uprights 8, triangular support frames 14, and a scaffolding safety net with stable support as described above. The uprights 8 are symmetrically arranged, and triangular support frames 14 are bolted to the outer side of one side of each of the two uprights 8 at equal intervals. Frame boards 6 are installed and fixed between the two triangular support frames 14 on the outer side of one side of each of the two uprights 8. The two hollow columns 7 are bolted to the outer side of one side of the triangular support frames 14 on the side away from the main frame 1.

[0039] In use: First, fix one side of each of the two hollow columns 7 to the outside of the triangular support frame 14. Then, fix the wall-mounted support on one side of the column 8 to the building. Next, fix the mounting frame 12 to the top of the two hollow columns 7 and the two columns 8. Then, fix the electric hoist 13 to complete the assembly of the entire frame. Next, insert the locking block 3 on one side of one of the main frames 1 through the limiting groove 10 and into the bottom of the hollow column 7. Then, fix the locking buckle at one end of the wire rope of the electric hoist 13 to the top of the main frame 1. Start the electric hoist 13, and the main frame 1 will be raised as a whole by winding the wire rope. At the same time, the locking block 3 on one side of the main frame 1 will move stably along the limiting groove 9. After raising it to a certain height, the operator will pick up the other main frame 1 and align it with the bottom of the main frame 1 that has been raised to the top. Then, use the splicing mechanism 4 to connect the two... The main frame 1 is spliced ​​and fixed, and then the electric hoist 13 continues to rewind and stretch. Following the above steps, multiple main frames 1 can be spliced ​​and stretched in sequence to cover the outer sides of the two hollow columns 7, thus covering one side of the scaffold. This splicing forms a whole protective net, completing the overall installation. In actual installation, workers only need to splice the main frames 1 in an orderly manner on the ground and then use the top electric hoist 13 to stretch and cover them. There is no need to use bolts to position and install each protective net panel individually, making the overall assembly simpler, more convenient, and safer, while improving the overall assembly efficiency. After the multiple main frames 1 are stretched and covered on the outside of the scaffold, the positioning mechanism 11 on one side can be used to fix and limit the multiple main frames 1 a second time, ensuring the stability of the overall assembly and splicing.

[0040] like Figure 2 , Figure 6 and Figure 10As shown, the top view of the card block 3 is T-shaped. The width of the second limiting groove 10 is greater than the width of the first limiting groove 9 and the card block 3, and the height of the second limiting groove 10 is greater than the height of the card block 3, so that the card block 3 can be completely inserted into the second limiting groove 10. The side of the card block 3 near the cavity column 7 is provided with a positioning groove 5. In use, because the height of the second limiting groove 10 is greater than the height of the card block 3 and the width of the second limiting groove 10 is greater than the width of the first limiting groove 9 and the card block 3, the card block 3 on one side of the main frame 1 can be completely inserted through the second limiting groove 10 and abut against the wall. The interior of the hollow column 7 allows one side of the main frame 1 to fit snugly against the outside of the hollow column 7. Simultaneously, the T-shaped design of the locking block 3 allows it to engage in the limiting groove 9. This ensures that when the electric hoist 13 pulls the main frame 1, the main frame 1 can move stably longitudinally within the limiting groove 9 on one side of the hollow column 7. This prevents the main frame 1 from swaying arbitrarily when the electric hoist 13 lifts and installs multiple assembled main frames, providing a certain degree of limiting and guiding effect, ensuring overall lifting and installation stability, and resulting in good overall performance.

[0041] like Figure 3 and Figure 4 As shown, the splicing mechanism 4 includes a suspension block 401, a mounting groove 402, a stop block 403, a rotating shaft 404, an extension block 405, a return spring 406, and a positioning bolt 407. The function of the splicing mechanism 4 is to longitudinally splice and fix the two main frames 1 together. The suspension block 401 is fixedly installed on the outside of the top side of the main frame 1, and the suspension block 401 is generally n-shaped. The mounting groove 402 is embedded in the bottom side of the main frame 1 near the suspension block 401. A rotating shaft 404 is rotatably installed inside the edge. A stop block 403 is fixed on one side of the rotating shaft 404, and the width of the stop block 403 is less than the distance between the inner walls of the suspension blocks 401. One end of the rotating shaft 404 is rotatably installed through the outside of one side of the main frame 1. An extension block 405 is fixed on the side of the rotating through end of the rotating shaft 404 away from the stop block 403. A return spring 406 is fixed on the top side of the extension block 405 away from the top of the rotating shaft 404, and the top of the return spring 406 is fixedly installed on the outside of one side of the main frame 1.

[0042] In use, when it is necessary to splice two main frames 1, the suspension block 401 at the top of the bottom main frame 1 can be inserted into the mounting groove 402 at the bottom of the top main frame 1. As the suspension block 401 is continuously inserted, it will abut against one side of the stop block 403 inside the mounting groove 402. Then, with the setting of the rotating shaft 404, the stop block 403 will rotate upward after being abutted by the suspension block 401. As the suspension block 401 is continuously inserted, the rotation angle of the stop block 403 will continuously increase. At the same time, the return spring 406 installed on the outer extension block 405 will continuously stretch, and in conjunction with the stop... The width of block 403 is smaller than the inner diameter of suspension block 401, so that when suspension block 401 is fully inserted into the mounting groove 402, one side of stop block 403 no longer abuts against the top crossbar of n-shaped suspension block 401. At this time, with the return spring 406 on one side, stop block 403 rotates and resets, so that stop block 403 is inserted into one side of n-shaped suspension block 401. This completes the splicing and fixing between the two main frames 1. The overall splicing is simple and the overall splicing stability is high, ensuring the connection stability of multiple spliced ​​main frames 1 during lifting and ensuring the overall assembly effect.

[0043] like Figure 5 As shown, a positioning bolt 407 is installed through the interior of the main frame 1 near the bottom of the stop 403. The top of the positioning bolt 407 is in contact with the outer surface of the bottom of the stop 403 to restrict the stop 403. During use, the bottom positioning bolt 407 positions the bottom of the stop 403, allowing the stop 403 to intercept and abut the top crossbar of the n-shaped suspension block 401, preventing the suspension block 401 from detaching from the top of the stop 403, thus achieving self-locking. When it is necessary to move the two main frames... When disassembling between the two main frames 1, simply rotate and retract the positioning bolt 407 that is in contact with the bottom of the stop block 403. This will remove the restriction of the positioning bolt 407 from the bottom of the stop block 403, allowing the stop block 403 to flip downwards. This will allow the suspension block 401, which is in contact with the top of the stop block 403, to be pressed down and released from the top of the stop block 403. This will allow the suspension block 401 to be released from the mounting groove 402, thus completing the disassembly operation between the two main frames 1. The overall structure is simple, the operation is convenient, and the overall performance is good.

[0044] like Figure 1 , Figure 7 , Figure 8 and Figure 9As shown, a positioning mechanism 11 is provided inside one side of the cavity column 7. The positioning mechanism 11 includes a slide rod 1101, an auxiliary block 1102, a guide groove 1103, a stop rod 1104, an auxiliary frame 1105, a stop block 1106, and a jack 1107. The slide rod 1101 is longitudinally slidably installed on the inner wall of one side of the cavity column 7 through the support block. The auxiliary blocks 1102 are fixedly inserted through the slide rod 1101 at equal intervals. The guide grooves 1103 are provided inside the auxiliary blocks 1102. The jacks 1107 are installed on the outer side of the bottom end of the cavity column 7, and the top output end of the jacks 1107 is fixedly installed to the bottom end of the slide rod 1101. The guide grooves 1103... For the inclined setting, each cavity column 7 has a horizontally arranged abutment rod 1104 on the side near the auxiliary block 1102. Each abutment rod 1104 has an auxiliary frame 1105 that slides through it on the side near the locking block 3. One end of the auxiliary frame 1105 is fixedly installed on the inner wall of one side of the cavity column 7. The abutment rod 1104 is L-shaped when viewed from above. The shorter end of the abutment rod 1104 is slidably engaged with the inside of one side of the guide groove 1103. An abutment block 1106 is fixedly installed on the side of the abutment rod 1104 near the locking block 3. The surface area of ​​the abutment block 1106 is smaller than the surface area of ​​the positioning groove 5, so that the abutment block 1106 can engage with the inside of the positioning groove 5 to restrict the main frame 1.

[0045] In use, after the multi-piece spliced ​​main frame 1 is stretched to the top by the electric hoist 13 to complete the installation and coverage of the entire protective net outside the cavity column 7, the multi-piece spliced ​​main frame 1 can be repositioned by the positioning mechanism 11 on one side to ensure the stability of the main frame 1 installed on one side of the cavity column 7, thereby ensuring the overall assembly effect and overall safety. The specific operation is as follows: First, rotate the jack 1107 on one side of the bottom of the cavity column 7. The jack 1107 can be an existing scissor jack. As the top of the jack 1107 is lifted upward, it drives the top sliding rod 1101 and the internally fixed auxiliary blocks 1102 at equal intervals to be lifted upward simultaneously. Multiple auxiliary frames 1105 on one side slide and engage with multiple abutment rods 1104, and the guide groove 1103 inclined inside the auxiliary block 1102 slides and engages with one end of the abutment rod 1104. This allows the multiple auxiliary blocks 1102 to squeeze and drive the multiple abutment rods 1104 on one side to move simultaneously to one side of the main frame 1 when they rise. The movement of the abutment rods 1104 drives the fixed abutment block 1106 on one side to move simultaneously. At the same time, in conjunction with the positioning groove 5 set on the outside of the locking block 3 on one side of the main frame 1, the abutment block 1106 moves a certain distance and then abuts into the inside of the positioning groove 5, thereby positioning the locking block 3 on one side and the external main frame 1, thus ensuring the stability of the multi-piece spliced ​​main frame 1 installation.

[0046] Meanwhile, when disassembling the main frame 1, simply rotate the jacks 1107 on both sides in the opposite direction, so that the jacks 1107 drive the slide bar 1101 to move downward as a whole, thereby causing the multiple abutment bars 1104 to drive the abutment blocks 1106 to disengage from the positioning groove 5, thereby causing the multiple main frames 1 on the side to lose their limit. Then, control the electric hoist 13 at the top to reverse so that the spliced ​​main frame 1 slowly descends. Then, disassemble and recycle it in sequence. The overall disassembly and assembly are convenient.
