Description

Technical Field

[0001] The present invention relates to the field of suspension bridge cable connection, in particular to a suspension bridge cable and a cable connecting device thereof. Background Art

[0002] As is known to all, suspension bridge cables are cables used on suspension bridges to supply power to various power facilities on the suspension bridges or cables passing through the suspension bridges;

[0003] When connecting cables, a cable connecting device is required to assist. In existing cable connecting devices, when in use, most of the core wires of the cables are first twisted together, and then a sealing structure and a protective structure are covered on the outside of the connection position. The connection strength of the cable connection position mainly depends on the connection strength of the cable core wires, and the external structure mainly plays a protective sealing role, which does not greatly improve the connection strength. Due to its own conditions, the suspension bridge cable requires a higher strength at the cable connection position. The application defects of this connection method and device setting in suspension bridge cables are more obvious. On the one hand, the operation is cumbersome when replacing the cable, and the cable at the original connection position often needs to be cut off, resulting in cable waste. On the other hand, the overall connection strength is insufficient, and there is a hidden danger of cable breakage at the cable connection position. Summary of the Invention

[0042] The following description is merely illustrative in nature and is not intended to limit the present disclosure, its applications, or uses. It should be understood that throughout the drawings, identical or similar reference numerals indicate identical or similar parts and features. The drawings merely schematically illustrate the concepts and principles of the embodiments of the present disclosure and do not necessarily depict the specific dimensions and proportions of the various embodiments of the present disclosure. Certain portions of certain drawings may be exaggerated to illustrate relevant details or structures of the embodiments of the present disclosure.

[0043] Example 1

[0044] Reference Figure 1 This embodiment provides a technical solution: a suspension bridge cable, including a cable body 1, the cable body 1 including a plurality of core wires 11 and a cable sheath 12 wrapping the core wires 11, and a filler 10 is further provided between the core wires 11 in the cable sheath 12. The filler 10 can improve the structural stability of the cable body 1, prevent the cable from deforming during stretching or compression, and maintain the overall shape of the cable.

[0045] Example 2

[0046] like Figure 2 - Figure 3As shown, this embodiment provides a technical solution: a cable connecting device 2, applied to the suspension bridge cable in Example 1, is used to connect two sections of cable body 1, and the cable connecting device 2 includes a first connecting part 20 and a second connecting part 21, wherein the first connecting part 20 is fixed to the end of one section of the cable body 1, and the second connecting part 21 is fixed to the end of the other section of the cable body 1, and the first connecting part 20 and the second connecting part 21 are connected by a detachable assembly, and a circuit conducting mechanism 3 is installed inside the first connecting part 20 and the second connecting part 21. When the first connecting part 20 and the second connecting part 21 are assembled and connected, the circuit conducting mechanisms 3 inside the first connecting part 20 and the second connecting part 21 are connected, so that the ends of the two sections of the cable body 1 are connected and the circuit is conducted.

[0047] Specifically, such as Figure 1 - Figure 4 and Figure 9 As shown, in order to achieve a detachable assembly connection between the first connecting portion 20 and the second connecting portion 21, in this embodiment, the first connecting portion 20 and the second connecting portion 21 both adopt a cylindrical structure with a variable cross-section, and the outer diameter of one end of the first connecting portion 20 and the second connecting portion 21 close to each other is larger than the outer diameter of the other end, wherein the outer portion of the first connecting portion 20 is movably sleeved with a fixing kit 200, and the opening of one end of the fixing kit 200 close to the second connecting portion 21 is larger than the opening of the other end, so that when the fixing kit 200 is sleeved on the outside of the first connecting portion 20 and moves toward the second connecting portion 21, the end with the smaller opening can be engaged with the variable cross-section position of the first connecting portion 20, and the inner wall of the end with the larger opening of the fixing kit 200 is provided with an internal thread structure;

[0048] The outside of the second connection part 21 is provided with an assembly sleeve 210, and the assembly sleeve 210 has an external thread structure. When the first connection part 20 and the second connection part 21 are connected, one end of the fixing kit 200 is screwed and sleeved on the assembly sleeve 210 through the threaded structure, so that the first connection part 20 and the second connection part 21 are fixedly connected. In actual application, the circuits of the two sections of the cable body 1 are first conducted through the circuit conduction mechanism 3 inside the first connection part 20 and the second connection part 21, and then the fixing kit 200 is moved. After the fixing kit 200 contacts the assembly sleeve 210, the fixing kit 200 is rotated to rotate and sleeve with the assembly sleeve 210, thereby completing the locking and fixing of the first connection part 20 and the second connection part 21. When disassembling, the fixing kit 200 is rotated in the opposite direction until it is disengaged from the assembly sleeve 210, thereby completing the separation of the first connection part 20 and the second connection part 21, and the operation is convenient and quick.

[0049] Specifically, such as Figure 2 and Figure 5As shown, in order to prevent the second connecting part 21 from rotating easily when the first connecting part 20 and the second connecting part 21 are connected, and to ensure a smooth connection process, in this embodiment, at least one auxiliary locking ear piece 211 is installed on the outside of the second connecting part 21. The auxiliary locking ear piece 211 has a through hole. When in use, a tool can be inserted into the through hole, and then the second connecting part 21 can be fixed by the tool so that it will not rotate during assembly, thereby facilitating assembly.

[0050] Specifically, such as Figure 5 and Figure 10 As shown, in order to achieve circuit connection between the two sections of the cable body 1 after the first connecting portion 20 and the second connecting portion 21 are connected, in this embodiment, the circuit conducting mechanism 3 inside the first connecting portion 20 and the second connecting portion 21 includes:

[0051] The core wire clamp 31 adopts a porous disc-shaped structure and is used to clamp and fix the core wire 11 inside the cable body 1;

[0052] There are two groups of terminal assemblies 32, each group has a certain number of the same number, and the two groups of terminal assemblies 32 are installed on the opposite sides of the two core wire clamps 31, and correspond one-to-one with the holes on the core wire clamps 31. When the first connecting part 20 and the second connecting part 21 are connected, the terminal assemblies 32 inside the first connecting part 20 and the second connecting part 21 are connected one-to-one to realize the circuit connection between the two sections of the cable body 1.

[0053] Specifically, such as Figure 10 - Figure 13 As shown, in order to realize the circuit connection between the two groups of terminal assemblies 32, in this embodiment, the two groups of terminal assemblies 32 both include a sleeve 32-1 and an outer rotating sleeve 32-2, wherein the sleeve 32-1 is fixed on the surface of the core wire chuck 31, and the inner diameter is consistent with the aperture on the core wire chuck 31, and the outer rotating sleeve 32-2 adopts a cylindrical structure and is screwed onto the sleeve 32-1 by threaded engagement, wherein the outer rotating sleeve 32-2 on one group of terminal assemblies 32 is provided with a first guide post 32-3, and the outer rotating sleeve 32-2 on the other group of terminal assemblies 32 is provided with a second guide post 32-6, and a guide sleeve 32-7 is installed at the front end of the second guide post 32-6, the first guide post 32-3 and the second guide post 32-6 both extend into the sleeve 32-1, and the guide sleeve 32-7 is adapted to the first guide post 32-3.

[0054] When the first connection part 20 and the second connection part 21 are connected, first, the core wire 11 in the cable body 1 is inserted into each sleeve 32-1 through the hole on the core wire clamping disc 31 and fixed, so that the first guide pin 32-3 and the second guide pin 32~6 are respectively electrically connected to the cables connected to them. Secondly, inside the first connection part 20 and the second connection part 21, the terminal assembly 32 located on the core wire clamping disc 31 is mutually connected with the first guide pin 32-3 through the guide sleeve 32-7, thereby realizing the circuit connection between the two groups of terminal assemblies 32.

[0055] Specifically, such as Figure 10 - Figure 13 As shown, in order to facilitate the rotational installation of the outer rotating sleeve 32-2, in this embodiment, a rotation auxiliary part 32-4 is installed on the top of the outer rotating sleeve 32-2. The rotation auxiliary part 32-4 adopts a regular polygonal structure. In this way, when rotating the outer rotating sleeve 32~2, it is convenient to use tools such as wrenches and socket wrenches to assist in rotation, ensuring that the outer rotating sleeve 32-2 can be tightened on the sleeve 32-1.

[0056] Specifically, such as Figure 10 - Figure 13 As shown, in order to ensure the connection between the core wire 11 and the sleeve 32-1 and improve the tensile strength of the connection position of the two sections of the cable body 1, in this embodiment, the first guide post 32-3 and the second guide post 32-6 are both provided with a wire pressing portion 32-5 at one end extending to the inside of the sleeve 32-1. The wire pressing portion 32-5 adopts a tapered structure with a diameter gradually reduced from the connection end with the first guide post 32-3 and the second guide post 32-6 to the other end along the central axis direction of the wire pressing portion 32-5. Such a structural setting makes it possible for the core wire 11 to be inserted into the sleeve 32-1 without passing through the inner portion. The core wire 11 is connected to the sleeve 32-1 by spot welding. It is only necessary to rotate the outer rotating sleeve 32-2 to gradually move the wire pressing part 32-5 into the sleeve 32-1. Since the wire pressing part 32-5 adopts a tapered structure, as the outer rotating sleeve 32-2 moves, the front end of the wire pressing part 32-5 is inserted between the multiple core wires 11 to squeeze the core wire 11, causing the core wire 11 to expand to both sides until it completely clamps the core wire 11 on the inner wall of the sleeve 32-1, that is, the core wire 11 and the sleeve 32-1 are locked. The operation is convenient and the disassembly is relatively convenient.

[0057] In summary, the cable connecting and guiding device 2 can conveniently and quickly fix the connection between two sections of cable, and can also quickly disassemble the connection position of the cable when the cable is replaced. At the same time, when the cable connecting and guiding device 2 is connecting the cable, all the core wires 11 inside the cable body 1 are divided into several parts, and are fixedly connected to each sleeve 32-1 respectively. In this way, the fixing force of the core wire 11 can be dispersed on each sleeve 32-1, so that the connection between the core wire 11 and the cable connecting and guiding device 2 is tighter, so that the two sections of cable have a better connection effect and higher stability after being connected.

[0058] Example 3

[0059] like Figure 4 and Figure 5 As shown, on the basis of Example 2, in order to facilitate the connection between the first connecting part 20 and the second connecting part 21 and the cable body 1, in this embodiment, the first connecting part 20 and the second connecting part 21 both include an outer shell 201 and an inner sleeve 202, wherein the inner sleeve 202 is detachably inserted into the outer shell 201, and the circuit conducting mechanism 3 is installed in the inner sleeve 202. Such a structural arrangement enables the first connecting part 20 and the second connecting part 21 to be connected to the cable body 1 by first inserting the end of the cable body 1 into the outer shell 201, and then connecting each core wire 11 to the circuit conducting mechanism 3 in the inner sleeve 202 respectively. After the connection is completed, the inner sleeve 202 is assembled into the outer shell 201. Therefore, the connection between the core wire 11 and the circuit conducting mechanism 3 does not need to be carried out in the first connecting part 20 and the second connecting part 21, making the operation more convenient.

[0060] Specifically, in order to achieve the snap connection between the outer shell 201 and the inner sleeve 202, in this embodiment, the inner sleeve 202 includes a cylindrical portion 202b and an eaves portion 202a arranged at one end of the cylindrical portion 202b, wherein the outer diameter of the eaves portion 202a is consistent with the outer diameter of the outer shell 201, so that the eaves portion 202a can be snapped on the end of the outer shell 201 and remain flush with it, facilitating the subsequent connection of the first connecting portion 20 and the second connecting portion 21, and the outer diameter of the cylindrical portion 202b is consistent with the inner diameter of the outer shell 201, so that after the inner sleeve 202 is assembled, the inner sleeve 202 can fit against the inner wall of the outer shell 201, thereby ensuring the stability and consistency of the entire structure.

[0061] Specifically, in order to increase the connection strength and tensile stress between the cable body 1 and the first connecting part 20 and the second connecting part 21, in this embodiment, an inner sandwich ring plate 2010 is provided on the inner side of the outer shell 201 close to the side where the cable body 1 is inserted. The inner diameter of the inner sandwich ring plate 2010 is consistent with the inner diameter of the end of the outer shell 201, and both are the same as the diameter of the cable body 1. The inner sandwich ring plate 2010 forms an inner layer 2011 between the inner wall of the outer shell 201 and the inner sandwich ring plate 2010, and the cylindrical part 202b is inserted into the inner sandwich 2011. The outer edge of the inner sandwich ring plate 2010 has a slope structure 2012, which can facilitate the insertion of the cylindrical part 202b and the carding of the cable sheath 12.

[0062] It should be noted that: on the one hand, the inner interlayer 2011 can make the cylindrical part 202b more stable after insertion, and on the other hand, it can accommodate a section of cable sheath 12, so that when the cylindrical part 202b is inserted into the inner interlayer 2011, it can cooperate to press the section of cable sheath 12 into the inner interlayer 2011, thereby making the connection strength between the cable body 1 and the first connecting part 20 and the second connecting part 21 higher.

[0063] Working principle:

[0064] In combination with Examples 1 to 3, when the device is used, the end of the cable body 1 is first inserted into the outer shell 201, and the preset length of the cable sheath 12 and the filler 10 at the front end of the cable body 1 are peeled off and removed, while a section of the cable sheath 12 is reserved, the reserved length of which is consistent with the depth of the inner interlayer 2011. The reserved section of the cable sheath 12 is then cut and flipped along the length direction so that it is flipped into the inner interlayer 2011. The inner sleeve 202 is then inserted into the outer shell 201, so that the cylindrical portion 202b of the inner sleeve 202 is inserted into the inner interlayer 2011, and the cable sheath 12 is pressed tightly into the inner interlayer 2011.

[0065] Secondly, the core wire 11 in the cable body 1 is divided into several strands, which are respectively inserted into the respective sleeves 32-1, and then fixed by assembling the outer rotating sleeve 32-2;

[0066] Finally, the first connecting portion 20 and the second connecting portion 21 are connected to each other, and after the circuit conducting mechanism 3 is connected, the fixing assembly 200 is rotated to be rotated and sleeved with the assembly assembly 210, thus completing the connection between the two sections of the cable body 1.

[0067] The exemplary implementation schemes proposed in the present disclosure are described in detail above with reference to preferred embodiments. However, it will be understood by those skilled in the art that, without departing from the concept of the present disclosure, various modifications and variations can be made to the above-mentioned specific embodiments, and various technical features and structures proposed in the present disclosure can be combined in various ways without exceeding the scope of protection of the present disclosure, which is determined by the appended claims.
