Description

Technical Field

[0001] The present invention relates to the technical field of protective equipment, and in particular to a construction protective equipment and a protective method for construction engineering. Background Art

[0002] With the increase in high-rise buildings and scaffolding, accidents caused by falling objects and people from heights occur frequently. Setting up protective nets around scaffolding can effectively solve or reduce the occurrence of accidents caused by falling objects and people from heights.

[0003] At present, the high-altitude fall prevention net is mainly composed of a frame and an anti-fall net installed in the frame. When workers working at heights accidentally fall, the anti-fall net can use its own elasticity to cushion and protect them, so as to reduce the injuries suffered by the workers. However, when falling, the weight of the workers and the force of falling will have a greater impact on the anti-fall net. At this time, the force between the anti-fall net and the frame becomes greater, causing the anti-fall net to be pulled. After a period of use, its structural strength cannot be guaranteed, which can easily cause the anti-fall net to loosen or break from the frame. Summary of the invention

[0019] A protection method for a construction project, using the above-mentioned construction protection equipment for a construction project, comprises the following steps:

[0020] S1: During the use of the construction protection equipment for construction projects, when a worker falls to the first protection belt, the first protection belt and the second protection belt will initially intercept and buffer the worker, and then the worker will continue to fall to the surface of the anti-fall net, causing the anti-fall net to move downward, thereby driving the first roller to move downward;

[0021] S2: When the first roller moves downward, it drives the second connecting member to move downward, so that the buffer arm drives the first connecting member, so that the first connecting member squeezes the first buffer spring to achieve secondary buffering and reduce the potential energy of the worker's fall. When the first roller descends, the buffer will also squeeze the second buffer spring to achieve further buffering, further reducing the potential energy generated by the worker's fall:

[0022] S3: When the anti-fall net moves downward, the first roller rotates while following the downward movement, thereby driving the first gear to rotate. The first gear can be used to rotate the second gear, so that the second gear drives the first rotating shaft to rotate.

[0024] The present invention provides a construction protection device and a protection method for construction engineering, which have the following beneficial effects:

[0025] 1. The construction protection equipment and protection method used in construction projects can initially reduce the potential energy of workers falling through the first protection belt and the second protection belt, thereby reducing the impact force on the anti-fall net. The buffer component can further reduce the potential energy of the anti-fall net and reduce the impact damage to workers when the anti-fall net is tightened.

[0026] 2. The construction protection equipment and protection method used in construction projects can protect the four sides of the anti-fall net through the side protection components, preventing workers from falling to the edge of the anti-fall net and falling again due to unstable body shape. At the same time, when the anti-fall net breaks, the rubber pad can continue to prevent the workers from falling, further improving the protection performance of the equipment. In conjunction with the support component, the anti-fall net and the rubber pad can be further supported, reducing the impact force on the anti-fall net and further reducing its breakage risk.

[0027] 3. The construction protection equipment and protection method used in construction projects can prevent tools from falling and hitting workers who are protected from falling through the cooperation between the protection components, the first protection belt and the second protection belt, and can also intercept tools that fall accidentally to avoid the problem of falling objects from high altitudes.

DETAILED DESCRIPTION

[0037] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0038] Example 1: Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 8 The present invention provides a technical solution: a construction protection device for a construction project, comprising an installation box 1, wherein the number of the installation boxes 1 is two and they are symmetrically arranged, a buffer assembly is arranged on the installation box 1, and the buffer assembly comprises a first roller 2, the first roller 2 is movably installed inside the installation box 1, and its two ends extend to the outside of the installation box 1, an anti-falling net 21 is arranged on the outer surface of the first roller 2, both sides of the inner cavity of the installation box 1 are fixedly installed with fixed blocks 22, a first support column 23 is fixedly installed between the two fixed blocks 22, a first buffer spring 24 is sleeved on the middle part of the outer surface of the first support column 23, both ends of the first buffer spring 24 are fixedly connected with a first connecting member 25, the first connecting member 25 is movably installed on the outer surface of the first supporting column 23, a buffer arm 26 is movably installed on the surface of the first connecting member 25, a second connecting member 27 is movably installed on one end of the buffer arm 26 away from the first connecting member 25, and the second connecting member 27 is movably installed on the outer surface of the first roller 2;

[0039] A second support column 28 is fixedly mounted on the upper surface of the fixed block 22, a first limit block 29 is fixedly mounted on the top of the second support column 28, a second buffer spring 210 is sleeved on the outer surface of the second support column 28, a buffer member 211 is movably mounted on the outer surface of the second support column 28, and one end of the buffer member 211 away from the second support column 28 is movably mounted on the outer surface of the first rotating roller 2;

[0040] The diameter of the first limit block 29 is greater than the diameter of the second support column 28. The bottom of the second buffer spring 210 is fixedly connected to the upper surface of the fixing block 22, and the top of the second buffer spring 210 is fixedly connected to the buffer member 211.

[0041] Both sides of the installation box 1 are provided with buffer grooves 212 adapted to the first roller 2, and both sides of the outer surface of the first roller 2 are fixedly sleeved with second limit blocks 213, which are located outside the installation box 1 and are in active contact with the installation box 1;

[0042] A first protection belt 214 is fixedly installed between the two installation boxes 1, a second protection belt 215 is arranged on the lower side of the first protection belt 214, and the first protection belt 214 and the second protection belt 215 are arranged alternately;

[0043] The installation box 1 is provided with a side protection component, which is used to improve the protection effect of the anti-fall net 21.

[0044] Specifically, when in use, it is first necessary to fix the frame around the scaffolding, then fix the installation box 1 on the frame, and make the two installation boxes 1 symmetrically arranged, so that the anti-falling net 21 is spread between the frames for protection. After the anti-falling net 21 is spread, it is necessary to make the anti-falling net 21 still wrap around the surface of the first rotating roller 2 for one circle;

[0045] When a worker makes a mistake and falls from the scaffold, the worker will first contact the first protection belt 214 and the second protection belt 215, and will be intercepted and buffered by the first protection belt 214 and the second protection belt 215, which will initially reduce the potential energy of the worker's fall, thereby reducing the impact force on the anti-fall net 21:

[0046] Furthermore, after the worker passes through the first protection belt 214 and the second protection belt 215, he will continue to fall to the surface of the anti-fall net 21. At this time, the anti-fall net 21 will be impacted and move downward. When the anti-fall net 21 moves downward, it will drive the first roller 2 to follow and fall in the buffer groove 212. When the first roller 2 moves downward, it will drive the second connecting member 27 to move downward, so that the buffer arm 26 drives the first connecting member 25, so that the first connecting member 25 squeezes the first buffer spring 24, and uses the resistance provided by the first buffer spring 24 to achieve secondary buffering, thereby reducing the worker's falling potential energy;

[0047] When the first roller 2 descends, the buffer member 211 will also squeeze the second buffer spring 210, and the resistance provided by the second buffer spring 210 is used to achieve a second buffer, further reducing the potential energy generated by the worker's descent and the impact force on the anti-fall net 21.

[0048] Furthermore, when the anti-fall net 21 descends, the anti-fall net 21 wound on the surface of the first roller 2 will be released, so that the anti-fall net 21 will extend as the worker falls. In conjunction with the second buffer spring 210 and the first buffer spring 24, the potential energy of the worker's fall will gradually be reduced during the extension of the anti-fall net 21. Compared with the traditional anti-fall net 21, when the anti-fall net 21 is tightened, the interaction between it and the worker will also become greater, which is easy to cause harm to the worker's body. The present invention can not only utilize multiple buffering and the extension and tightening of the anti-fall net 21, but also reduce the impact on the anti-fall net 21 and increase its service life, and can also reduce the impact damage to the worker caused by excessive falling potential energy.

[0049] Example 2: Please refer to Figures 1 to 4 The side protection assembly includes a support rod 3, which is fixedly installed between the two installation boxes 1, and the number of the support rods 3 is two, and the two support rods 3 are respectively located on both sides of the anti-fall net 21;

[0050] A fixing ring 31 is fixedly installed on the outer surface of the support rod 3, a drawstring 32 is fixedly connected to the surface of the fixing ring 31, and one end of the drawstring 32 away from the fixing ring 31 is fixedly connected to the anti-fall net 21;

[0051] Side protection belts 33 are provided on both sides of the installation box 1. The side protection belts 33 are fixedly connected between the two installation boxes 1. A rubber pad 34 is fixedly installed between the two installation boxes 1.

[0052] The rubber pad 34 is located inside the side protection belt 33 , and the lowermost side protection belt 33 is located below the rubber pad 34 .

[0053] The conventional anti-fall net 21 is directly fixed by a frame, so there is no protective structure around it. When a worker falls to the edge of the anti-fall net 21, it is easy for the anti-fall net 21 to be unable to hold the worker, causing the worker to slip from the edge of the anti-fall net 21 and fall again.

[0054] On the basis of Example 1, when the worker falls onto the anti-fall net 21, the anti-fall net 21 will be extended so that the two sides of the anti-fall net 21 are in a "V" shape to protect the worker, and the other two sides of the anti-fall net 21 are pulled by the pull belt 32. At this time, the other two sides of the anti-fall net 21 will also be in a "V" shape to protect the worker;

[0055] Furthermore, when the worker falls to the edge of the anti-fall net 21, the anti-fall net 21 will move downward, so that the drawstring 32 is close to the side protection belt 33. Since the drawstring 32 is arranged longitudinally and the side protection belt 33 is arranged transversely, when the drawstring 32 and the side protection belt 33 are close to each other, the two will form a "cross"-shaped grid, which further protects the worker and prevents him from falling again due to unstable body shape when he falls to the edge of the anti-fall net 21.

[0056] Furthermore, after the anti-falling net 21 has finished extending and the second buffer spring 210 and the first buffer spring 24 have finished buffering, the force between the anti-falling net 21 and the worker gradually increases, and the rubber pad 34 can be used to support the anti-falling net 21 and the worker, share the force on the anti-falling net 21, and further reduce the impact force on the anti-falling net 21;

[0057] On the other hand, when the anti-fall net 21 breaks, the rubber pad 34 can be used to further prevent the worker from falling. In addition, when the rubber pad 34 shares the function, it will also be stretched and deformed downward. Since the lowermost side protection belt 33 is below the rubber pad 34, it can further prevent the worker from falling from the side of the rubber pad 34.

[0058] Example 3: Please refer to Figures 1 to 6 A support assembly is provided on the first rotating roller 2, and the support assembly includes a first gear 4. The first gear 4 is two in number and is fixedly mounted on both ends of the first rotating roller 2, respectively. A second gear 41 is meshed on the lower side of the first gear 4;

[0059] A first rotating shaft 42 is fixedly installed in the middle of the second gear 41, one end of the first rotating shaft 42 is movably installed on the buffer 211, a first fixing frame 43 is fixedly installed on the end of the first rotating shaft 42 away from the buffer 211, a second rotating roller 44 is fixedly installed on the inner side of the first fixing frame 43, and a rubber stick 45 is provided on the outer surface of the second rotating roller 44.

[0060] On the basis of Example 1, when the anti-falling net 21 wound on the surface of the first roller 2 is extended, the first roller 2 will be subjected to the friction force generated during the extension of the anti-falling net 21, thereby rotating. When the first roller 2 rotates, it can drive the first gear 4 to rotate, and the first gear 4 can drive the second gear 41 to rotate, so that the second gear 41 drives the first shaft 42 to rotate, and the first shaft 42 can drive the first fixed frame 43 to rotate, so that the first fixed frame 43 drives the second roller 44 to rotate, so that the rubber stick 45 flips to the bottom of the rubber pad 34, and then supports the rubber pad 34. The rubber stick 45 can support the anti-falling net 21, and further reduce the force on the anti-falling net 21.

[0061] It should be noted that when the first roller 2 is installed, a torsion spring can be provided on it, which can assist the first roller 2 to reset after operation. Secondly, the anti-falling net 21 is spread at an upper position adjacent to the first roller 2. In specific operation, Figure 4As shown, one end of the anti-falling net 21 is fixed to the side of the adjacent first rotating roller 2 close to each other, and then the other end of the anti-falling net 21 is rolled up from the bottom of one of the first rotating rollers 2 to the top, and then stretched to the top of the other first rotating roller 2, and rolled up along the top of the other first rotating roller 2 to the bottom, and the other end of the anti-falling net 21 is fixed to it, and the spreading of the anti-falling net 21 is completed; in this way, in the anti-falling operation, Figure 4 As shown, the first rotating roller 2 on the front side rotates clockwise, and the first rotating roller 2 on the rear side rotates counterclockwise, so that the two rubber sticks 45 are both located below the spread part of the anti-falling net 21 after turning over, and the operation is successfully completed.

[0062] Example 4: Please refer to Figure 1 and Figure 7 A protection assembly is provided on the first gear 4, and the protection assembly includes a second shaft 5, which is fixedly mounted on the middle of the first gear 4, and a second fixing frame 51 is fixedly mounted on one end of the second shaft 5 away from the first gear 4, and a rubber sleeve 52 is fixedly mounted on the inner side of the second fixing frame 51, and a protective plate 53 is provided on the outer surface of the rubber sleeve 52;

[0063] There is a gap between the bottom of the rubber sleeve 52 and the top of the installation box 1 , and a magnetic attraction plate 54 is fixedly installed on the top of the rubber sleeve 52 , and the tops of the magnetic attraction plates 54 on the two rubber sleeves 52 are magnetically attracted to each other.

[0064] During the construction process, tools are indispensable. When a worker falls due to a mistake, his tools may also fall, which may easily cause the tools to hit the worker who is protected by the anti-fall net 21 and cause injury.

[0065] The situation where the tool falls and hits the worker can generally be divided into two situations. First, the tool falls with the worker in a short period of time after the worker falls. In this case, the distance between the tool and the worker is short, and the damage caused by the impact is not high, but the worker will be hit more quickly. Second, after the worker falls to the anti-fall net 21, the tool falls due to vibration and other reasons. In this case, the damage caused by the impact is more serious, but there is a period of time before the impact.

[0066] On the basis of Example 1, for the first tool falling situation, when the time interval between the worker and the tool falling is short, when the worker just falls onto the anti-fall net 21, the tool starts to fall, and the first protection belt 214 and the second protection belt 215 are staggered and staggered up and down, which not only enables the worker to quickly fall to the surface of the anti-fall net 21 after being initially buffered, but also blocks the falling tool to prevent it from causing damage to the worker;

[0067] On the basis of Example 3, for the second tool falling situation, when the time interval between the worker and the tool falling is long, after the worker has fallen onto the anti-fall net 21, the tool starts to fall. In Example 3, when the first gear 4 rotates, it will drive the second rotating shaft 5 to rotate, and the second rotating shaft 5 will drive the second fixing frame 51 to rotate, so that the rubber sleeve 52 is turned over, until the two rubber sleeves 52 are turned over to the horizontal state, and when the rubber sleeve 52 is in the horizontal state, the two magnetic suction plates 54 are attracted to each other to maintain balance;

[0068] At this time, the rubber sleeve 52 can be used to block the falling tools, and the first protective belt 214 and the second protective belt 215 can more effectively prevent the tools from causing damage to the workers. It should be noted that during the production process, the installation box 1 can be covered with rubber to prevent the workers from being injured by the collision of parts of their bodies with the installation box 1 during the falling process.

[0069] On the basis of Examples 1-4, the present invention further provides a protection method for a construction project, using the above-mentioned construction protection equipment for a construction project, comprising the following steps:

[0070] S1: When the worker falls to the first protection belt 214, the first protection belt 214 and the second protection belt 215 will initially intercept and buffer the worker, and then the worker will continue to fall to the surface of the anti-fall net 21, causing the anti-fall net 21 to move downward, thereby driving the first rotating roller 2 to move downward;

[0071] S2: When the first roller 2 moves downward, it will drive the second connecting member 27 to move downward, so that the buffer arm 26 drives the first connecting member 25, so that the first connecting member 25 squeezes the first buffer spring 24 to achieve secondary buffering and reduce the potential energy of the worker's fall. When the first roller 2 descends, the buffer member 211 will also squeeze the second buffer spring 210 to achieve secondary buffering, further reducing the potential energy generated by the worker's descent:

[0072] S3: When the anti-fall net 21 moves downward, the first roller 2 rotates while following the downward movement, thereby driving the first gear 4 to rotate. The first gear 4 can be used to rotate the second gear 41, so that the second gear 41 drives the first rotating shaft 42 to rotate. The first rotating shaft 42 can drive the first fixing frame 43 to rotate, so that the rubber stick 45 moves to the bottom of the rubber pad 34 to support the rubber pad 34 and the worker.

[0073] S4: When the first gear 4 rotates, it will drive the second rotating shaft 5 to rotate. The second rotating shaft 5 can drive the second fixing frame 51 to rotate, so that the second fixing frame 51 drives the rubber sleeve 52 to rotate, and the rubber sleeve 52 can be rotated to a horizontal state, thereby providing further protection for the workers.

[0074] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
