[0002] During the construction of buildings, there is a risk of falling (people or objects) when working at heights. Therefore, it is necessary to build a safety anti-fall net around the construction site to protect construction workers so that workers or falling objects can be supported to avoid serious safety accidents. At present, most of the existing safety anti-fall devices are made of steel rods with nylon nets hanging or pulled on the rods to catch falling people or objects. However, these existing devices have some functional deficiencies in actual use, which are mainly reflected in the following aspects:

Once partially damaged, the whole net needs to be replaced, which not only increases maintenance costs but also reduces construction efficiency.

[0004] (2) Insufficient buffering performance: When falling objects impact the anti-fall net, the existing devices lack an effective buffering mechanism and cannot effectively reduce the impact force, which may cause damage to the anti-fall net and supporting structure, and even fail to fully protect the safety of the falling person.

[0048] The technical solutions of the embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0049] In the description of the embodiments of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "top", "bottom", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "set" and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, or it can be a connection between the two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0050] Reference Figure 1-7The present embodiment provides a safety anti-falling device for building construction, which includes: a support seat 1, a piston buffer 2, a protection frame 3, a traction rope 4, an installation rope 5 and a protection mesh 6. The piston buffer 2 and the protection frame 3 are respectively located on both sides of the support seat 1, the bottom end of the protection frame 3 is rotatably connected to the bottom end of the support seat 1, and the top of the protection frame 3 is connected to the piston buffer 2 through the traction rope 4 that passes through the top of the support seat 1; a plurality of installation ropes 5 are arranged on the inner side of the protection frame 3, and the two sides of each group of installation ropes 5 are respectively connected to the protection mesh 6.

[0051] When in use, first fix the support seat 1 to the construction area to be protected, fix the piston buffer 2 to the non-airside side of the construction area, place the protective mesh 6 and the protective frame 3 pre-connected with the traction rope 4 on the airside of the construction area, and adjust the angle between the bottom end of the protective frame 3 and the support seat 1 to adapt to different working conditions. Finally, connect and tighten the traction rope 4 to the piston buffer 2. Several groups of installation ropes 5 are arranged on the inner side of the protection frame 3, and protection meshes 6 are connected to both sides of the installation ropes 5 respectively. Multiple groups of protection meshes 6 are spliced ​​to form a complete large protection net to protect the construction workers. Since the protection meshes 6 are connected to both sides of the installation ropes 5 respectively, there are no protection loopholes between adjacent protection meshes 6, which can effectively ensure the safety of the operation. When the protection meshes 6 are damaged by falling objects during construction, the damaged protection meshes 6 can be replaced individually instead of replacing the large protection net in the protection frame 3 as a whole, which can save costs. In addition, when falling objects impact the protection mesh 6, since the protection frame 3 is connected to the piston buffer 2 by the traction rope 4, the piston buffer 2 is driven by the traction rope 4 to reduce the impact force on the protection frame 3 and the protection mesh 6, protect the protection frame 3 and the protection mesh 6, prevent them from being cracked and damaged when subjected to a large impact and unable to effectively receive falling objects from high altitude, and extend their service life.

[0052] The above-mentioned support seat 1 includes a support column 1.1, a first support 1.2 and a second support 1.3. The first support 1.2 is located at the top of the support column 1.1, and is provided with a rope hole 1.23 and a fixed pulley. The rope hole 1.23 and the fixed pulley are used to install the traction rope 4 to guide and support the traction rope 4; the second support 1.3 is located at the bottom of the support column 1.1, and is provided with a hinged seat 1.4. The hinged seat 1.4 is hinged to the bottom end of the protective frame 3 to facilitate the adjustment of the inclination angle of the protective frame 3 to adapt to different construction conditions.

[0053] To facilitate installation and fixation, the first support 1.2 is constructed to include a first fixing plate 1.21 and a first fixing sleeve 1.22. The bottom end of the first fixing sleeve 1.22 is sleeved on the support column 1.1, and the top end is connected to the first fixing plate 1.21; the second support 1.3 is constructed to include a second fixing plate 1.31 and a second fixing sleeve 1.32. The top end of the second fixing sleeve 1.32 is sleeved on the support column 1.1, and the bottom end is connected to the second fixing plate 1.31; the first fixing plate 1.21 and the second fixing plate 1.31 are respectively fixed to the top floor and the bottom floor of the construction area by anchor bolts, so that the support base 1 is stably placed in the construction area to improve the protection effect.

[0054] In order to better guide and support the traction rope 4 and reduce material wear, in this embodiment, a cross tube 7 is passed through the middle of the first fixed sleeve 1.22, and the fixed pulley is configured to include: a first fixed pulley 8 configured at the top of the first fixed plate 1.21, a second fixed pulley 9 and a third fixed pulley 10 configured at the bottom of the first fixed plate 1.21, and the second fixed pulley 9 and the third fixed pulley 10 are respectively located on both sides of the cross tube 7; one end of the traction rope 4 is connected to the protective frame 3, and the other end is connected to (or passes through) the first fixed pulley 8, the rope hole 1.23, the second fixed pulley 9, the cross tube 7, and the third fixed pulley 10 in sequence, and then connected to the piston buffer 2.

[0055] The first fixed pulley 8 redirects the traction rope 4 so that it can pass through the rope hole 1.23 smoothly, and reduces the direct contact between the traction rope 4 and the first fixed plate 1.21, thereby reducing wear; the second fixed pulley 9 redirects the traction rope 4 so that it can pass through the cross pipe 7 smoothly, and disperses the tension of the traction rope 4 to reduce the local load; the third fixed pulley 10 redirects the traction rope 4 so that it can be connected to the piston buffer 2; in addition, by optimizing the relative height of the second fixed pulley 9 and the third fixed pulley 10 and the cross pipe 7, the friction between the traction rope 4 and the cross pipe 7 can also be reduced. The first fixed pulley 8, the second fixed pulley 9 and the third fixed pulley 10 cooperate to guide and support the traction rope 4, reduce the wear and local load of the traction rope 4, and extend its service life.

[0056] Reference Figure 5 The piston buffer 2 includes a piston cylinder 2.1, a piston rod 2.2 and a buffer spring 2.3. The piston rod 2.2 is movably arranged in the piston cylinder 2.1, the top end of which extends out of the piston cylinder 2.1 and is connected to the traction rope 4, and the bottom end is provided with a piston head 2.4 located in the piston cylinder 2.1, and the piston head 2.4 slides against the inner side wall of the piston cylinder 2.1; the buffer spring 2.3 is sleeved on the outside of the piston rod 2.2, and the two ends respectively abut against the inner top wall of the piston cylinder 2.1 and the piston head 2.4; when objects fall from a high altitude, the double buffering mechanism of the piston buffer 2 is used to reduce the impact force on the protection frame 3 and the protection mesh 6, thereby protecting the protection frame 3 and the protection mesh 6.

[0057] The above-mentioned double buffer mechanism includes: since the interior of the piston cylinder 2.1 is a closed space, when the protection frame 3 is impacted and pulls the traction rope 4, the piston rod 2.2 will move upward and drive the piston head 2.4 to move upward, the volume of the space below the piston head 2.4 increases, and the total amount of gas remains unchanged. According to Boyle's law (when the temperature remains unchanged, the volume of the gas is inversely proportional to the pressure), the air pressure below the piston head 2.4 will drop sharply, and the sudden drop in air pressure will produce a downward reaction force, which will offset part of the external force and play a buffering role. This is the first layer of buffering; and when the piston head 2.4 moves upward, the buffer spring 2.3 is squeezed upward and begins to shrink. The contraction of the buffer spring 2.3 will absorb part of the energy, thereby further reducing the impact of the external force. The elastic deformation of the spring can effectively disperse and absorb the impact force, making the impact of the entire system more stable. This is the second layer of buffering. As the impact is reduced, the traction rope 4 slowly resets a little. After the falling object is removed from the high altitude, the buffer spring 2.3 resets and drives the traction rope 4 to reset completely.

[0058] Reference Figure 6 The protection frame 3 includes a first mounting rod 3.1, a second mounting rod 3.2 and two sets of sleeves. The first mounting rod 3.1 and the second mounting rod 3.2 are arranged in parallel, and the bottom ends are respectively connected to different hinge seats 1.4; the two sets of sleeves are respectively sleeved on the first mounting rod 3.1 and the second mounting rod 3.2, and the two ends of the mounting rope 5 are respectively connected to the two sets of sleeves. The sleeves can be sleeved or removed from the top of the first mounting rod 3.1 or the second mounting rod 3.2, and the installation and disassembly are convenient. The mounting rope 5 can be arranged in multiple groups along the axial direction of the sleeves, so as to install multiple groups of protective meshes 6 along the axial direction of the sleeves, so as to form a large protective net in the protection frame 3. When the protective meshes 6 are partially damaged, only the protective meshes 6 of the damaged parts can be replaced, so as to reduce the cost.

[0059] In addition, the sleeve may be configured as a plurality of coaxially distributed basic sleeves 3.3, with the ends of adjacent basic sleeves 3.3 abutting against each other. If a basic sleeve 3.3 is damaged, only the damaged portion of the basic sleeve 3.3 may be replaced, thereby reducing costs.

[0060] In this embodiment, the top ends of the first mounting rod 3.1 and the second mounting rod 3.2 are respectively provided with rope threading rings 3.4, and the bottom ends are respectively provided with limiting ring plates 3.5. The rope threading rings 3.4 are used to connect the traction rope 4. The outer diameter of the limiting ring plate 3.5 is larger than the inner diameter of the sleeve. On the one hand, the limiting ring plate 3.5 can isolate the sleeve from the hinge seat 1.4 to prevent mutual obstruction. On the other hand, the plate surface of the limiting ring plate 3.5 is perpendicular to the axis of the sleeve, which can provide better support for the sleeve.

[0061] In order to facilitate the installation and removal of the protective mesh 6, a plurality of C-shaped buckles 11 are sleeved on the installation rope 5, and connecting ears 12 are respectively configured at both ends of the C-shaped buckle 11, and two sets of connecting ears 12 are locked by connecting bolts 13 inserted therein. When installing the protective mesh 6, the connecting ear 12 at one end is passed through the protective mesh 6, and then the two connecting ears 12 are connected and locked. The side end of the protective mesh 6 can be tied and fixed to the sleeve by ropes, or the above-mentioned C-shaped buckle 11 of a larger size can be sleeved on the sleeve, and connected to the protective mesh 6 in the same way as above, so as to prevent the protective gap between the side wall of the sleeve and the protective mesh 6.

[0062] In order to protect people or objects falling from height, the outer wall of the sleeve is coated with a flexible protective layer to avoid rigid scratches on people or objects, and the outer wall of the C-shaped buckle 11 is coated with a flexible wear-resistant layer to reduce the wear of the protective mesh 6 and increase its service life.

[0063] Compared with the prior art, the beneficial effects of the present invention include: multiple groups of protective meshes 6 are spliced ​​together to form a large protective net. When the protective meshes 6 are damaged by falling objects during construction, the damaged protective meshes 6 can be replaced individually instead of replacing the large protective net in the protective frame 3 as a whole, which can save costs; when falling objects impact the protective mesh 6, since the protective frame 3 is connected to the piston buffer 2 by the traction rope 4, the piston buffer 2 is driven by the traction rope 4 to reduce the impact force on the protective frame 3 and the protective mesh 6, thereby protecting the protective frame 3 and the protective mesh 6 from being cracked and damaged when subjected to a large impact and being unable to effectively receive falling objects from high altitudes, and extending their service life.

[0064] 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.

[0065] The above are preferred embodiments of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
