Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering protection, in particular to an elastic protection net for construction engineering. Background Art

[0002] Safety nets used in construction projects are usually protective measures to prevent people and objects from falling from heights. It is generally made of steel wire ropes, chemical fiber materials or wire mesh, and can be installed at the edge of a building, stairwells, elevator shafts and other locations. The main function of the safety net is to intercept and buffer workers or objects when they fall accidentally, reducing the occurrence of injuries. It can effectively prevent people from falling from heights and protect the lives of workers. In addition, the safety net can also prevent building materials, tools and other items from falling on people or equipment below to avoid accidents. At the same time, it can also play a certain role in dust prevention and fire prevention, protecting the environment and safety of the construction site.

[0003] In construction projects, the setting and use of safety nets is very important and must comply with relevant safety standards and regulations. During use, regular inspections and maintenance are also required to ensure their reliability and effectiveness. This is the only way to ensure the safety of construction sites and protect the lives and property of workers.

[0004] Existing safety nets are usually fixed in shape and cannot be deformed under the impact force, that is, they must completely absorb the impact force in a very short time. This will cause the safety net to tear due to excessive impact, causing falling objects to continue to fall through the safety net. Utility Model Content

[0005] In order to overcome the above technical problems, the utility model provides an elastic protective net for construction engineering, which is used to improve the problem that the protective net is easily torn.

[0006] In order to achieve the above-mentioned purpose, the utility model proposes an elastic protective net for construction projects, including a storage tube, a storage shaft rotatably connected to the storage tube, a sliding sleeve sleeved on the outside of the storage shaft and slidably connected to the storage shaft, a coil spring fixed between the sliding sleeve and the storage shaft, a safety net wound on the sliding sleeve, and a fixed column fixed at the outermost end of the safety net.

[0007] The storage shaft is fitted with a sleeve, and the safety net is wrapped around the sleeve. The storage tube and the fixed column are fixed to the scaffolding respectively, with the safety net stretched out in the middle to block falling objects. When the safety net is impacted, the sleeve uses the coil spring to pull the safety net out under the action of tension, which plays a role in slowing down the impact.

[0008] Preferably, there are multiple sliding sleeves.

[0009] A plurality of sliding sleeves are provided to wrap around separate safety nets respectively, so that the utilization rate of the safety nets can be reduced, the strength of all safety nets being pulled outward can be increased, and the wear of the separate sliding sleeves and coil springs can be reduced.

[0010] Preferably, elastic nets are connected between adjacent safety nets.

[0011] The elastic net is arranged between adjacent safety nets, so that the two sets of safety net devices can be linked, and the wear of the individual sliding sleeves and coil springs can be reduced. When subjected to external impact, the safety net that directly contacts the impact plays the main blocking role, while the adjacent safety net plays the auxiliary blocking role through the elastic net, increasing the blocking force, reducing the wear of the adjacent sliding sleeves and coil springs, and ensuring that falling objects will not be exposed from the gaps between adjacent protective nets.

[0012] Preferably, the elastic net and the safety net are connected by a zipper.

[0013] The elastic net is connected to the safety net through a zipper, which makes it easy to replace and install the elastic net.

[0014] Preferably, one end of the storage shaft passes through the storage tube.

[0015] One end of the storage shaft passes through the storage cylinder, and the storage shaft can be manually rotated to store the safety net back into the storage cylinder.

[0016] Preferably, a groove is provided at the top of the storage tube, and a clamping rod cooperating with the groove is fixedly provided at one end of the storage shaft passing through the storage tube.

[0017] The storage tube is provided with a groove, and the storage shaft is provided with a clamping rod. When releasing the safety net, the fixed position of the rotating shaft is not limited first, until the safety net meets the coverage area, the clamping rod is clamped in the groove, and the sliding sleeve does not apply external force to the coil spring. When encountering an impact force, the sliding sleeve will rotate relative to the rotating shaft, and the coil spring will be triggered to apply tension to the safety net to reduce the impact force.

[0018] Preferably, there are multiple grooves.

[0019] Providing multiple grooves to match multiple clamping rods can increase the firmness of the fixation.

[0020] Preferably, the axial length of the clamping rod is greater than the axial length of the groove.

[0021] The length of the clamping rod is set to be greater than the axial length of the groove, so as to facilitate the removal and placement of the clamping rod from the groove.

[0022] The elastic protection net for construction projects provided by the utility model is provided with a rotating shaft, and a sliding sleeve is sleeved on the outside of the rotating shaft, and a force is generated between the sliding sleeve and the rotating shaft through a coil spring. When encountering an impact force, the coil spring can slow down the impact, avoid the safety net from being torn due to the rigid bearing of the impact force, and reduce safety risks.

[0028] Embodiments of the present invention are described below with reference to the accompanying drawings. Elements and features described in one drawing or one embodiment of the present invention may be combined with elements and features shown in one or more other drawings or embodiments. It should be noted that for the purpose of clarity, the representation and description of components or processes that are not related to the present invention and are known to those of ordinary skill in the art are omitted in the drawings and descriptions.

[0029] The utility model is further described below in conjunction with the accompanying drawings.

[0030] like Figure 1 , Figure 2 , Figure 3 As shown, the elastic protection net for construction engineering provided by the utility model includes a storage tube 1, a storage shaft 2 rotatably connected to the storage tube 1, a sliding sleeve 3 sleeved on the outside of the storage shaft 2 and slidably connected to the storage shaft 2, a coil spring 7 fixed between the sliding sleeve 3 and the storage shaft 2, a safety net 4 wound on the sliding sleeve 3, and a fixing column 5 fixed to the outermost end of the safety net 4.

[0031] The sliding sleeve 3 is sleeved on the storage shaft 2, and the safety net 4 is wound on the sliding sleeve 3. The storage tube 1 and the fixing column 5 are fixed on the scaffold respectively, and the safety net 4 is stretched out in the middle to block the falling objects. When the safety net 4 is impacted, the sliding sleeve 3 uses the coil spring 7 to pull the safety net 4 out under the action of tension, which plays a role in alleviating the impact.

[0032] If the safety net 4 is completely fixed on both sides and has no elastic buffer, it is very easy to cause the safety net 4 to tear after being impacted. The torn safety net 4 can no longer protect against falling objects, and may even entangle the falling objects and cause secondary damage. The coil spring 7 between the sliding sleeve 3 and the rotating shaft plays a buffering role for the safety net 4, avoiding the risk of the safety net 4 tearing.

[0033] In one embodiment of the present invention, there are multiple sliding sleeves 3 .

[0034] A plurality of sliding sleeves 3 are provided to wrap around separate safety nets 4 respectively, so that the utilization rate of the safety nets 4 can be reduced, the strength of pulling out all the safety nets 4 can be increased, and the wear of the separate sliding sleeves 3 and the coil springs 7 can be reduced.

[0035] In one embodiment of the present invention, an elastic net 6 is connected between adjacent safety nets 4 .

[0036] The elastic net 6 is arranged between adjacent safety nets 4, so that the two groups of safety nets 4 can be linked together and the wear of the individual sliding sleeves 3 and the coil springs 7 can be reduced. When subjected to external impact, the safety net 4 directly in contact with the impact plays a major blocking role, while the adjacent safety nets 4 play an auxiliary blocking role through the elastic net 6, increasing the blocking force, reducing the wear of the adjacent sliding sleeves 3 and the coil springs 7, and ensuring that falling objects will not be exposed from the gaps between adjacent protective nets.

[0037] In one embodiment of the present invention, the elastic net 6 and the safety net 4 are connected by a zipper.

[0038] The elastic net 6 is connected to the safety net 4 via a zipper, which makes it easy to replace and install the elastic net 6.

[0042] The storage cylinder 1 is provided with a groove 8, and the storage shaft 2 is provided with a clamping rod 9. When releasing the safety net 4, the fixed position of the rotating shaft is not limited first, until the safety net 4 meets the coverage area, the clamping rod 9 is clamped in the groove 8, and at this time, the sliding sleeve 3 does not apply external force to the coil spring 7. When encountering an impact force, the sliding sleeve 3 will rotate relative to the rotating shaft, and the coil spring 7 will be triggered to apply tension to the safety net 4 to reduce the impact force.

[0043] In one embodiment of the present invention, there are multiple grooves 8 .

[0044] Providing a plurality of grooves 8 to match a plurality of clamping rods 9 can increase the firmness of the fixation.

[0045] In one embodiment of the present invention, the axial length of the clamping rod 9 is greater than the axial length of the groove 8 .

[0046] The length of the clamping rod 9 is set to be greater than the axial length of the groove 8, so as to facilitate the removal and placement of the clamping rod 9 from the groove 8.

[0047] The elastic protection net for construction projects provided by the utility model is provided with a rotating shaft, and a sliding sleeve is sleeved on the outside of the rotating shaft, and a force is generated between the sliding sleeve and the rotating shaft through a coil spring. When encountering an impact force, the coil spring can slow down the impact, avoid the safety net from being torn due to the rigid bearing of the impact force, and reduce safety risks.
