Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of slope protection engineering, in particular to a steel wire rope net and an intersection node structure of the steel wire rope net. Background Art
[0002] The flexible protection system for geological disasters is a protection system with the basic protection concept of preventing or delaying the occurrence of disastrous geological processes and avoiding or reducing their hazards. This system is widely used in slope protection engineering and takes the flexible net as the main characteristic load-bearing member. The flexible net includes an active protection net, a passive protection net and a guiding protection net. Among them, the mesh sheets in the covering areas of the active protection net and the guiding protection net mainly bear the bursting force and the horizontal tensile force. In the existing forms of the mesh sheets, the structural performance of the intersection nodes is poor. The structure at the intersection nodes may be that one steel wire rope forms an insertion hole and intersects with the insertion hole formed by another steel wire rope (the first case), or two steel wire ropes are connected by adding fasteners to form an intersection node (the second case). However, in both of these two types of structures, the mechanical properties at the intersection nodes are poor. Especially in the second structure, fasteners are needed to achieve the connection, so there is also the problem of the relatively high overall price of the mesh sheet.
[0003] In view of this, it is necessary to develop a new type of mesh sheet with better overall mechanical properties and lower cost for application in the flexible protection system to improve the protection level of the protection system and ensure the economic property and life safety of people. Summary of the Utility Model
[0004] The technical problem to be solved by the utility model is to provide an intersection node structure with better mechanical properties and lower cost and a steel wire rope net including the intersection node.
[0005] The technical solution adopted by the utility model to solve its technical problem is: In the first aspect, the utility model provides an intersection node structure. The intersection node is formed by the combination of two segments on the steel wire rope. The steel wire rope includes at least two sub-steel wire ropes. It is characterized in that at the position where the two segments are combined, the sub-steel wire ropes in one segment are woven with the sub-steel wire ropes in the other segment to form the intersection node.
[0006] Wherein, the segment refers to a section of the steel wire rope with a certain length in a certain interval on the steel wire rope.
[0007] In the above technical solution, by weaving the sub-steel wire ropes of two segments on the steel wire rope to form an intersection node, such an intersection node is relatively special. The sub-steel wire ropes of the two segments are woven together, no longer independent of each other, but restrict and involve each other, so as to avoid the disadvantages brought by stress concentration, improve the problem of poor mechanical properties at the intersection node, and enhance the mechanical properties.
[0008] Furthermore, the cross node is formed by the combination of two segments on the same steel wire rope.
[0009] Furthermore, the cross node is formed by the combination of two segments respectively located on two steel wire ropes.
[0010] Furthermore, the steel wire rope is made by twisting n sub-wire ropes; the cross node is formed by interweaving n sub-wire ropes in one segment with n sub-wire ropes in the other segment; where 3 ≤ n ≤ 6.
[0011] Furthermore, the interweaving is: each sub-wire rope in one segment interpenetrates and winds around each sub-wire rope in the other segment.
[0012] Furthermore, the interpenetrating and winding around each other is: interpenetrating and winding around each other in the braid weaving form.
[0013] In a second aspect, the present utility model also provides a steel wire rope net, characterized in that the steel wire rope net comprises a plurality of cross nodes, and at least a part of all the cross nodes are the cross nodes described in any one of the foregoing items.
[0014] Furthermore, the cross nodes make the steel wire rope net form a plurality of mesh holes; except for the mesh holes located at the edge of the steel wire rope net, the remaining mesh holes tend to be rhombic.
[0015] Furthermore, when the cross node is the cross node described in any one of the foregoing items, the length of the cross node is L1, and the length of the steel wire rope between adjacent cross nodes is L2, where 1:4 ≤ L1 / L2 ≤ 1:5.
[0016] In the above technical solution, the cross nodes in the steel wire rope net adopt the cross node structure of the foregoing technical solution. Therefore, the problem of poor mechanical properties at the cross nodes of the steel wire rope net can be improved, the overall mechanical properties of the steel wire rope net can be enhanced, the integrity is stronger during use, the structural mechanical properties are better, and the steel wire rope net of the present utility model adopts a reasonable weaving method, and can also complete the weaving of the cross nodes at a lower cost, and the manufacturing cost has a certain advantage. When applied in a flexible protection system, the protection energy level of the protection system can be improved, and the economic property and life safety of people can be guaranteed.
[0017] In a third aspect, based on the cross-node structure provided in the first aspect above, in the third aspect of the present invention, a cross-node structure for a non-steel wire rope net is also provided. That is, this cross-node structure can be applied to a hemp rope net or a rope net woven from ropes made of other materials except hemp ropes and steel wire ropes. Specifically, this cross-node is formed by the combination of two segments on the rope. The rope includes at least two sub-ropes. At the position where the two segments are combined, the sub-ropes in one segment are woven with the sub-ropes in the other segment to form the cross-node. Among them, the rope is a non-steel wire rope. That is, in the third aspect of the present invention, the rope can be a hemp rope or a rope made of other materials except hemp ropes and steel wire ropes. BRIEF DESCRIPTION OF THE DRAWINGS
[0018] Figure 1 is a schematic structural diagram of the steel wire rope net of the present invention;
[0019] Figure 2 is Figure 1 an enlarged view of the dashed box in DETAILED DESCRIPTION OF THE EMBODIMENTS
[0020] The present invention will be further introduced in detail below with reference to specific embodiments, but the embodiments of the present invention are not limited thereto.
[0021] See Figure 1 and Figure 2 The present invention provides a steel wire rope net. This steel wire rope net 100 can be woven from a single steel wire rope 110 or from two steel wire ropes 110.
[0022] That is, when weaving the steel wire rope net 100 of the present invention, there are at least the following weaving methods: (1) Gradually release the coiled steel wire rope 110 from a single reel and gradually weave the steel wire rope net 100 only using the steel wire rope 110 on this reel. Since the steel wire rope 110 released from a single reel is continuous and unbroken, the steel wire rope net 100 woven in this way is the one woven from a single steel wire rope 110 as described above; (2) Gradually release the coiled steel wire rope 110 from two reels and jointly gradually weave the steel wire rope net 100 using the steel wire ropes 110 on these two reels. The steel wire rope net 100 woven in this way is the one woven from two steel wire ropes 110 as described above;
[0023] Of course, in some uncommon cases, the steel wire rope net 100 can also be woven from more than two steel wire ropes 110. The weaving method in this case is as follows: Gradually release the coiled steel wire rope 110 from more than two reels and jointly gradually weave the steel wire rope net 100 using the steel wire ropes 110 on these more than two reels.
[0024] It should be noted that although the above method of braiding the wire rope net 100 using more than two wire ropes 110 is not common and does not meet the requirements of the technical specifications in this field, such braiding methods should not be excluded from the protection scope of the present utility model.
[0025] During braiding, different segments on the wire rope 110 will combine with each other to form several crossing nodes 1b. Specifically:
[0026] If the wire rope net 100 is braided from one wire rope 110, then the several crossing nodes 1b are formed by the combination of different segments on this wire rope 110;
[0027] If the wire rope net 100 is braided from two or more wire ropes 110, then the several crossing nodes 1b can be formed by the combination of different segments on one wire rope 110, or can be formed by the combination of two segments respectively located on different wire ropes 110.
[0028] Among them, the above-mentioned segment refers to: a section of the wire rope 110 with a certain length in a certain interval on the wire rope 110.
[0029] Among them, the wire rope 110 includes at least two strands of sub-wire ropes 111. Usually, the wire rope 110 is formed by twisting 6 or 8 strands of sub-wire ropes 111, and each strand of sub-wire rope 111 is in turn formed by twisting several fine steel wires (not marked in the figure), that is, several fine steel wires are twisted into a strand of sub-wire rope 111, and finally, 6 or 8 strands of sub-wire ropes 111 are twisted into a wire rope 110.
[0030] In the wire rope net 100 of the present utility model, at the position where two segments are combined with each other, the sub-wire ropes 111 in one segment will be braided with the sub-wire ropes 111 in the other segment to form the crossing node 1b. Specifically:
[0031] If the wire rope net 100 is braided from one wire rope 110, then the crossing node 1b is formed by the braiding of the sub-wire ropes 111 in different segments on this wire rope 110;
[0032] If the wire rope net 100 is braided from two or more wire ropes 110, then the crossing node 1b can be formed by the braiding of the sub-wire ropes 111 in different segments on one wire rope 110, or can be formed by the braiding of the sub-wire ropes 111 in two segments respectively located on different wire ropes 110.
[0033] In a preferred embodiment, the mutual braiding is as follows: each strand of the sub-steel ropes 111 in one segment is interlaced and intertwined with each strand of the sub-steel ropes 111 in the other segment. In some other embodiments, the mutual braiding may also be: each strand of the sub-steel ropes 111 in one segment is twisted together (or, can also be called twisted together) with each strand of the sub-steel ropes 111 in the other segment. This twisting method is the same as the twisting method of each strand of the sub-steel ropes 111 at the non-crossing nodes of the steel wire rope 110, and it is a way of braiding in which each strand of the sub-steel ropes 111 spirally surrounds and progresses along an axis, and the sub-steel ropes 111 keep closely fitting with each other during the braiding process. Of course, the mutual braiding is not limited to the forms described above. As long as at the crossing node 1b, the sub-steel ropes 111 in the two segments are not independent of each other, and the sub-steel ropes 111 in the two segments can be entangled with each other without relying on other external components (similar to the second case in the background art), achieving a situation of mutual restraint and mutual check, it can be considered as belonging to the form of the mutual braiding described above. It should be noted that: the first case in the background art does not belong to the form of the mutual braiding described above, because in the first case, the sub-steel ropes 111 in the two segments are independent of each other and there is no situation of being entangled with each other.
[0034] Among them, the above-mentioned mutual interlacing means that any one strand of the sub-steel ropes 111 in a certain segment can be interlaced between two or more strands of the sub-steel ropes 111 in the same segment and / or another segment.
[0035] Among them, the above-mentioned mutual entanglement means that on the basis of the above mutual interlacing, there is also a situation where one strand of the sub-steel ropes 111 in a certain segment is entangled with the sub-steel ropes 111 in the same segment and / or another segment.
[0036] That is to say, at the crossing node 1b, the sub-steel ropes 111 and the sub-steel ropes 111 will first interlace with each other, then entangle with each other, then interlace with each other again, and then entangle with each other again. After multiple mutual interlacings and mutual entanglements, the crossing node 1b is finally formed.
[0037] Further, the mutual interlacing and mutual entanglement are: interlacing and entangling with each other in the braiding manner of a braid.
[0038] Preferably, when the steel wire rope 110 is made of three strands of sub-steel ropes 111 twisted together, the crossing node 1b is formed by six strands of sub-steel ropes 111 in two segments interlacing and entangling with each other in the braiding manner of a braid, and the braiding form of the braid can be braided in the form of a square six-strand braid, a flat six-strand braid, a round six-strand braid or a flat six-strand braid.
[0039] In a preferred embodiment, the cross nodes 1b cause the wire rope net 100 to form a number of mesh holes 1a; except for the mesh holes 1a located at the edge of the wire rope net 100, the remaining mesh holes 1a tend to be diamond-shaped.
[0040] Further, the length of the cross node 1b is L1, and the length of the wire rope 110 between adjacent cross nodes 1b is L2, where 1:4 ≤ L1 / L2 ≤ 1:5.
[0041] Generally, for the wire rope net 100 formed by braiding, the anti-detachment tensile force at each cross node 1b should not be less than 10 kN. The magnitude of this anti-detachment tensile force is comprehensively determined by parameters such as the number of strands of the sub-wire ropes 111 in the wire rope 110, the number of fine steel wires in the sub-wire ropes 111, the length of the cross node 1b, and the specific braiding method used. Usually, the specific situation of the above parameters can be finally determined through calculation and / or testing so that the anti-detachment tensile force at each cross node 1b of the wire rope net 100 after braiding is not less than 10 kN.
[0042] For the wire rope net 100 of the present utility model, by making the sub-wire ropes 111 of two segments of the wire rope 110 braid with each other to form the cross node 1b, such a cross node is relatively special. The sub-wire ropes 111 of the two segments are braided together with each other, no longer independent of each other, but restrict and involve each other, thereby avoiding the drawbacks brought by stress concentration, improving the problem of poor mechanical properties at the cross node 1b, and further enhancing the overall mechanical properties of the wire rope net 100. When in use, the integrity is stronger, and the structural mechanical properties are better. Moreover, for the wire rope net 100 of the present utility model, with a reasonable braiding method, the braiding of the cross node can also be completed at a lower cost, and the manufacturing cost has certain advantages. When applied in a flexible protection system, it can improve the protection energy level of the protection system and ensure the economic property and life safety of people.
[0043] Based on the above cross node structure in the wire rope net, it is obvious that the above cross node structure can also be applied in non-wire rope nets. For example, this cross node structure can be applied in a hemp rope net or in a rope net braided with ropes made of other materials except hemp ropes and wire ropes. Specifically, the cross node is formed by the combination of two segments of the rope. The rope includes at least two sub-ropes. At the position where the two segments are combined, the sub-ropes in one segment are braided with the sub-ropes in the other segment to form the cross node; wherein, the rope is a non-wire rope. That is, the rope here can be a hemp rope or a rope made of other materials except hemp ropes and wire ropes. When applied in other non-wire rope nets, this cross node structure can also avoid the problem of stress concentration and improve the overall mechanical properties of the rope net.
[0044] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, the present utility model may have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
