Description

Technical Field

[0001] The utility model belongs to the technical field of construction site protection equipment, and particularly relates to a protection structure for a construction site. Background Art

[0002] There are various protection equipment for construction sites, including personal protection facilities such as safety helmets, safety shoes and safety ropes, collective protection facilities such as safety nets and guardrails, and protection articles such as dust masks and protective gloves. Among them, the safety net used in construction sites is a common protection structure, which can effectively prevent objects falling from above or around the construction site from injuring pedestrians or equipment, including bricks, stones, tools, building materials, etc. At the same time, it can also prevent people from accidentally falling and provide certain safety protection;

[0003] The existing protection structures such as safety nets or protection nets for construction sites are generally made of materials with strong weather resistance, such as polyethylene, polypropylene or polyester. During use, the protection net only relies on its own performance to buffer when facing the impact of falling objects, which results in the phenomenon that the protection net is easily penetrated, thus posing a threat to workers. Moreover, the installation of the protection is rather cumbersome, reducing the work efficiency. Therefore, it is necessary to make improvements. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a protection structure for a construction site aiming at the above existing technical problems, so as to reduce the phenomenon that the protection net is penetrated and facilitate the installation of the protection net.

[0011] Wherein, the protection net is wound on the elastic winding roller, one end of the protection net can be connected to the fixing mechanism, and the buffer part can buffer the impact by controlling the elastic winding roller when the protection net is impacted.

[0012] In this technical solution, when installing the protective net, one end of the protective net is stretched towards the fixing mechanism. After the protective net is pulled out from the elastic winding roller and unfolds to form a horizontal interception, then one end of the protective net is fixed on the fixing mechanism, thus completing the installation. The elastic winding roller can tension the protective net through self-winding. When the protective net is impacted by a falling object, the protective net buffers through its own performance. At the same time, the buffer part can control the rotation of the elastic winding roller, so as to control the slow unfolding of the protective net as the falling object drops, thereby buffering the impact. Compared with the prior art, the protective net of the present utility model is simply installed and can effectively buffer the impact generated by the falling object, preventing the protective net from being penetrated, and ensuring the personal safety of workers.

[0023] Second friction blocks, which are movably arranged in the second movable grooves;

[0024] Second springs, which are arranged in the second movable grooves and the two ends of the second springs are respectively connected to the second friction blocks and the second movable grooves;

[0025] A braking groove, which is arranged on the inner wall of the housing;

[0026] Wherein, the elastic coefficient of the second spring is greater than that of the first spring, and the second friction block can cooperate with the braking groove.

[0027] In the above technical solution, further, the fixing mechanism further includes:

[0028] A fixing seat, on which a pressing plate is movably arranged;

[0050] Embodiment 1:

[0051] An embodiment of the present application provides a construction site protection structure, including: a protection net 1, which is composed of a mesh cloth;

[0052] It further includes: a storage rack 2, on which an elastic winding roller 3 is provided; a fixing rack 4, on which a fixing mechanism 5 is provided; a buffer part 6, which is arranged on the storage rack 2 and is located at one end of the elastic winding roller 3;

[0053] Wherein, the protection net 1 is wound on the elastic winding roller 3, one end of the protection net 1 can be connected to the fixing mechanism 5, and the buffer part 6 can buffer the impact by controlling the elastic winding roller 3 when the protection net 1 is impacted.

[0054] In this embodiment, when installing the protection net 1, one end of the protection net 1 is stretched towards the fixing mechanism 5. After the protection net 1 is pulled out from the elastic winding roller 3, it unfolds to form a horizontal interception. Then, one end of the protection net 1 is fixed to the fixing mechanism 5, thus completing the installation. The elastic winding roller 3 can tension the protection net 1 through self-winding. When the protection net 1 is impacted by a falling object, the protection net 1 buffers through its own performance. At the same time, the buffer part 6 can control the rotation of the elastic winding roller 3, so as to control the protection net 1 to slowly fall and unfold as the falling object drops, thereby buffering the impact. Compared with the prior art, the protection net 1 of the present utility model is simple to install and can effectively buffer the impact generated by the falling object, preventing the protection net 1 from being penetrated and ensuring the safety of workers.

[0055] Embodiment 2:

[0056] This embodiment provides a protective structure for a construction site. In addition to including the technical solutions of the above embodiment, it also has the following technical features. The buffer part 6 further includes: a connecting rotating shaft 7, which is rotatably arranged on the storage rack 2 and connected to one end of the elastic winding roller 3, and the connecting rotating shaft 7 can rotate together with the elastic winding roller 3; a connecting rod 8, which is arranged at the end of the connecting rotating shaft 7 away from the elastic winding roller 3, and there are two connecting rods 8 symmetrically distributed along the radial direction of the connecting rotating shaft 7; a counterweight 9, which is arranged at the outer end of the connecting rod 8, and two first movable grooves 10 are arranged on the end face of the counterweight 9; a first friction block 11, which is movably arranged in the first movable groove 10; a first spring 12, which is arranged in the first movable groove 10 and the two ends of the first spring 12 are respectively connected to the first friction block 11 and the first movable groove 10; a housing 13, which is arranged on the storage rack 2, and a friction layer is arranged on the inner wall of the housing 13;

[0057] Wherein, the housing 13 covers the outside of the connecting rotating shaft 7, and the first friction block 11 can extend out of the first movable groove 10 with the rotation of the connecting rotating shaft 7 and contact the friction layer on the inner wall of the housing 13.

[0058] It further includes: a second movable groove 14, which is arranged on the end face of the counterweight 9 and located between the two first movable grooves 10; a second friction block 15, which is movably arranged in the second movable groove 14; a second spring 16, which is arranged in the second movable groove 14 and the two ends of the second spring 16 are respectively connected to the second friction block 15 and the second movable groove 14; a braking groove 17, which is arranged on the inner wall of the housing 13;

[0059] Wherein, the elastic coefficient of the second spring 16 is greater than that of the first spring 12, and the second friction block 15 can cooperate with the braking groove 17.

[0060] In this embodiment, when the protective net 1 is impacted by a falling object, the protective net 1 is further deployed from the elastic winding roller 3 under the action of the impact, and drives the elastic winding roller 3 to rotate. The connecting rotating shaft 7 rotates along with the rotation of the elastic winding roller 3, driving the counterweight 9 to rotate around the connecting rotating shaft 7. The first friction block 11 extends out of the first movable groove 10 under the action of centrifugal force to overcome the limitation of the first spring 12 and contacts the friction layer on the inner wall of the housing 13. Through the action of friction, the rotation of the elastic winding roller 3 is hindered, so that the protective net 1 can effectively buffer the impact of the falling object, preventing the protective net 1 from being penetrated instantaneously due to excessive impact. At the same time, when the falling object is too heavy, since the impact of the falling object on the protective net 1 is greater at this time, the protective net 1 drives the elastic winding roller 3 to rotate faster. The second friction block 15 simultaneously overcomes the limitation of the second spring 16 and extends out of the second movable groove 14 to contact the friction layer on the inner wall of the housing 13. Through the action of the first friction block 11 and the second friction block 15, the rotation of the elastic winding roller 3 is hindered, so that the protective net 1 can effectively buffer the impact of the falling object, and finally the second friction block 15 can be caught in the braking groove 17, and the second friction block 15 tightly abuts against the inner wall of the braking groove 17 under the action of the gravity of the falling object, thereby preventing the protective net 1 from falling further. Compared with the prior art, the utility model can effectively buffer the impact generated by the falling object, prevent the protective net 1 from being penetrated, and ensure the personal safety of workers.

[0061] Embodiment 3:

[0063] The fixing mechanism 5 further includes: a connecting block 23, which is arranged at the top of the fixing frame 4, and a telescopic cavity 24 is arranged in the connecting block 23; a telescopic rod 25, one end of which is connected to the fixing seat 18, and the other end is movably inserted into the telescopic cavity 24 and is provided with a limiting block; a fourth spring 26, which is sleeved on the telescopic rod 25 and is located in the telescopic cavity 24.

[0064] In this embodiment, after the protective net 1 is unfolded, the pressing plate 19 is moved upward. Then, one end of the protective net 1 is inserted between the pressing plate 19 and the fixed seat 18. The pressing plate 19 is released to preliminarily fix the end of the protective net 1 on the fixed seat 18. Then, the pressing plate 19 is pressed tightly against the fixed seat 18 by the fastening bolt 22 to completely fix the protective net 1. When the protective net 1 is impacted by a falling object, the fixed seat 18 receives the pulling force of the protective net 1, causing the telescopic rod 25 to move. The elastic force of the fourth spring 26 can further buffer the impact.
