The invention will be described in detail with reference to the following embodiments with reference to the attached drawings.
A high-safety protection net, as shown in fig. 1 to 4, comprises a main frame 1 and a suspension frame 2 on the main frame, wherein a safety net assembly is installed on the suspension frame, and the main frame is fixed on a scaffold or a building. Suspension frame is in main frame top, is equipped with several guide post 3 at suspension frame lower extreme equipartition, and each guide post is equidistant to be arranged, guarantees that suspension frame and main frame cooperation are stable, and after the safety net subassembly was loaded, suspension frame was moving at vertical direction for main frame. The main frame is equipped with the guiding hole corresponding to the guide post, the guide post slides the cartridge in the guiding hole, has all arranged first order elastic buffer 4 and second level elastic buffer 5 simultaneously in each guide post outside.
The two-stage buffer piece forms buffering in a layered mode, the buffering effect is improved, and meanwhile when the suspension frame is infinitely close to the main frame, the two-stage buffer piece can keep certain rigidity between the suspension frame and the main frame, and the effect of braking at the buffering end is equivalent.
In an alternative embodiment, the first stage elastic buffer member includes a first stage spring sleeved outside the guide post, and the upper end of the first stage spring abuts against the lower surface of the suspension frame and the lower end abuts against the upper surface of the main frame.
In an optional embodiment, the second-stage elastic buffer member includes a second-stage spring disposed outside the guide post, and the upper end of the second-stage spring is fixed to the suspension frame, and a buffer gap is left between the lower end of the second-stage spring and the main frame, or the lower end of the second-stage spring is fixed to the main frame, and a buffer gap is left between the upper end of the second-stage spring and the suspension frame.
In order to ensure smooth sliding fit between the guide post and the guide hole, the roughness of the outer wall of the guide post and the roughness of the inner wall of the guide hole are both smaller than 1.6 mu m. The connecting arms are arranged at the lower part of the suspension frame at equal intervals, so that the stress condition is balanced and the stability is high.
In an optional embodiment, the length of the connecting arm is smaller than the distance between the suspension frame and the main frame in a normal state, when the safety net body is designed in such a structure, if the safety net body is subjected to instantaneous severe impact force, the main frame can also play a role in blocking and unloading the part of the safety net close to the suspension frame (namely the root of the safety net body), especially the part of the safety net body, which is not subjected to vertical downward impact force, when certain horizontal component force exists, the safety net body can be instantly attached to the inner edge of the main frame, the stability is better, the safety is better, and the protection net structure is not easy to damage.
Above-mentioned safety net subassembly includes that safety net body 11 and suspension frame go up a plurality of linking arms 6 that are used for fixed safety net body, is equipped with 1 at least auxiliary connection structure 7 between two adjacent linking arms. A hanging ring 10 is arranged at the lower end of the auxiliary connecting structure.
Auxiliary connection structure's structural strength is less than linking arm structural strength, and according to operating mode actual need, the biggest pulling force design that can bear auxiliary connection structure falls for ordinary people 1 floor, impact force when 2 floors or 3 floors, if the thing that falls the impact force that produces is greater than the design impact force, then allow auxiliary connection structure to break off, draw the safety net body and break off in the twinkling of an eye at auxiliary connection structure, can form effective buffering, and, auxiliary connection structure can be earlier than its linking arm disconnection near, furthest protects the linking arm, avoid damaging as main connection structure's linking arm, ensure the holistic security of safety net device.
For example, the weight of a common person is calculated according to about 70-80 kg, the height of the floor 1 is calculated according to 3-3.5 m, and the impact force generated when the falling height is the floor 1, the floor 2 or the floor 3 can be conveniently obtained through experimental simulation or physical formula calculation. The determination of the maximum tensile force of the auxiliary connecting structure can also be determined by experiments or formula calculation.
For example, the auxiliary connecting structure comprises an upper connecting body 8 and a lower connecting body 9, wherein a hanging ring is arranged at the lower end of the lower connecting body, and the hanging ring is hooked at a corresponding position of the safety net body.
The upper connector and the lower connector are connected through threads, because the maximum bearing tension values of different thread diameters are different, and the maximum bearing tension of different thread diameters generally has empirical values or experimental measured data, therefore, a person skilled in the art can design the specific structures (such as the thread diameter of a thread matching part) of the upper connector and the lower connector through the load borne by the threads, and the upper connector and the lower connector are allowed to be disconnected after exceeding the maximum bearing tension to a certain limit.
Or the lower connecting body and the upper connecting body are riveted and fixed, the maximum bearing tension of the upper connecting body and the lower connecting body is determined through the maximum load of the rivet, and the upper connecting body and the lower connecting body are allowed to be disconnected after the bearing tension of the upper connecting body and the lower connecting body exceeds a maximum allowable value to a certain limit.
As a further improved scheme, a threaded or riveted connection mode is also adopted between the hanging ring and the lower connecting body, the designed value of the maximum tensile force borne between the hanging ring and the lower connecting body is equivalent to the stress of the joint of the lower connecting body and the upper connecting body, so that when the hanging ring and the lower connecting body are subjected to severe impact, double insurance is formed between the hook and the lower connecting body and between the lower connecting body and the upper connecting body, the effect that the auxiliary connecting structure weakens the impact force can be realized as long as one connecting structure is disconnected, the effect of the main connecting arm is protected, the buffering performance is improved, the device is also protected, and the service life of the device is prolonged.
The auxiliary connecting structure effectively shares the load of the connecting arm, even if the auxiliary connecting structure is severely impacted, the auxiliary connecting structure is decomposed into two parts, the impact force can be effectively buffered, after the auxiliary connecting structure is disconnected, the impact force borne by the connecting arm is greatly weakened, and in addition, the buffering effect of the two-stage elastic buffering parts can effectively buffer people or objects falling into the safety net body, so that the influence caused by the generated impact force is reduced to the maximum extent, and the safety is higher.
Usually, 1, 2 or 3 auxiliary connecting structures are arranged between two adjacent connecting arms. Each connecting arm equipartition sets up in suspension frame lower extreme. The suspension frame adopts a rectangular frame, a circular frame or an oval frame. The main frame adopts a rectangular frame, a circular frame or an elliptical frame. The invention is not a pursuit reinforced structure, because the unlimited reinforced structure can bring the weight increase and the cost increase, which is not beneficial to the modern energy-saving and environment-friendly concept, therefore, the invention can be used against the situation, even the auxiliary connecting structure is allowed to be disconnected when necessary, so as to protect the connecting arm, ensure the good integral stability of the safety net device, the connecting arm plays the main connecting role of the frame and the safety net body, the stress point is clear, the auxiliary connecting structure can effectively share the load, the impact force is greatly weakened, and when severe impact (large impact force and serious falling condition) occurs, the safety of the connecting arm part is ensured by sacrificing the auxiliary connecting structure.
The safety net component is fixed on the suspension frame, the two-stage elastic buffer parts are arranged between the suspension frame and the main frame, and when buffering is carried out, the first-stage elastic buffer parts are from light to heavy until the second-stage elastic buffer parts are inserted, so that the rigidity is enhanced and the buffering effect is improved while buffering is carried out.
Simultaneously, be equipped with supplementary connection structure on the suspension frame, when the safety net body received great impact force, after supplementary connection structure performance buffering shock attenuation performance, allowed its disconnection, formed the protection to the linking arm, the safety net device is more reliable, and the cushioning effect is better.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and should not be taken as limiting the invention, so that any modifications, equivalents, improvements and the like, which are within the spirit and principle of the present invention, should be included in the scope of the present invention.
