Description

Technical Field

[0001] This application relates to the field of cable laying technology, and in particular to a cable splicing auxiliary device. Background Technology

[0002] Cables are wire products used to transmit electromagnetic energy, information, and convert electromagnetic energy. During cable installation, the cable position needs to be adjusted according to the actual situation; therefore, an adjustment frame is required to adjust the cable during installation.

[0003] When laying electrical wires and cables, splicing is necessary. However, existing methods require manual pulling of the cables to be spliced, resulting in weak connections and a tendency for them to detach. Furthermore, during cable splicing, the spliced ​​portions are often misaligned or coaxial. Manual splicing alone cannot ensure a stable connection, compromising signal continuity and transmission efficiency.

[0004] Therefore, there is an urgent need for a cable splicing auxiliary device to solve the above problems. Utility Model Content

[0040] like Figures 1-5As shown, a cable splicing auxiliary device includes a mounting base 10, a drive assembly 20, two lifting assemblies 30, two splicing discs 11, and two constraint assemblies 40. The mounting base 10, which has a hollow internal structure, is placed horizontally on a working surface, and a notch 101 is provided on the top of the mounting base 10. The two lifting assemblies 30 are vertically and symmetrically spaced on the top of the mounting base 10, and the fixed ends of the two lifting assemblies 30 extend into the interior of the mounting base 10 through the notch 101. The two splicing discs 11 are fixedly disposed on the free ends of the corresponding lifting assemblies 30 on the side away from the mounting base 10, and the center of the two splicing discs 11 is provided with a light hole 111 for the cable to pass through. The drive assembly 20 is disposed inside the mounting base 10, and the two working ends of the drive assembly 20 are threadedly connected to the side of the corresponding lifting assembly 30 located inside the mounting base 10, for driving the two lifting assemblies 30 to synchronously move closer to or away from the center of the mounting base 10 along the width direction of the notch 101. The two constraint assemblies 40 are fixedly disposed on the side of the corresponding splicing disc 11 away from the center of the mounting base 10.

[0041] In the above scheme, when the drive assembly 20 is activated, since the two working ends of the drive assembly 20 are threadedly connected to the corresponding lifting assemblies 30, under the action of the drive assembly 20, the two lifting assemblies 30 will synchronously move closer to or away from the center of the mounting base 10 along the width direction of the notch 101 (i.e., the direction perpendicular to the top of the mounting base 10), thereby achieving precise adjustment of the horizontal position of the docking plate 11. As the two docking plates 11 approach each other, the lifting assemblies 30 can drive the docking plates 11 to rise or fall vertically, adjusting the vertical docking position of the cables and achieving precise docking of the two cables. During the cable docking process, the constraint assembly 40 fixed on the docking plate 11 can constrain and fix the cables, preventing them from shifting or shaking during docking, ensuring the stability and accuracy of the docking.

[0042] The drive assembly 20 includes a drive motor 21, two screws 22, and a connecting sleeve 23. The drive motor 21 is disposed inside the mounting base 10, and the output end of the drive motor 21 extends into the mounting base 10. The two screws 22 are spaced apart inside the mounting base 10, and one end of each screw 22 is fixedly connected to the end of the corresponding lifting assembly 30 located inside the mounting base 10. The connecting sleeve 23 is sleeved on the end of each screw 22 away from the lifting assembly 30, and the periphery of the connecting sleeve 23 is rotatably connected to the output end of the drive motor 21.

[0043] This is feasible. In this application, the output end of the drive motor 21 and the connecting sleeve 23 are driven by a gear meshing mechanism to rotate the connecting sleeve 23. Furthermore, a driven gear is fixedly provided on the periphery of the connecting sleeve 23, and a driving gear is provided on the output end of the drive motor 21.

[0044] In the above scheme, the connecting sleeve 23 is sleeved on the end of the two screws 22 away from the lifting assembly 30, and its periphery is rotatably connected to the output end of the drive motor 21. When the drive motor 21 rotates, the connecting sleeve 23 rotates accordingly, and through the threaded engagement with the two screws 22 (and the docking plate 11 and the lifting assembly 30 connected thereto), the rotational motion is converted into linear motion, driving the two screws 22 to synchronously approach or move away from the center of the mounting base 10 along the width direction of the notch 101 inside the mounting base 10, so that the two docking plates 11 and the lifting assembly 30 move synchronously together, stabilizing and adjusting the horizontal position of the docking plate 11 in the mounting base 10, while reducing the impact of human factors on the cable docking quality.

[0045] The lifting assembly 30 includes a fixed base 31, a telescopic cylinder 32, and a cylinder signal generator 33. The fixed base 31 is vertically placed inside the mounting base 10. The middle part of the fixed base 31 is threadedly connected to the corresponding screw 22, and the bottom of the fixed base 31 is slidably connected to the inner bottom wall of the mounting base 10. The fixed end of the telescopic cylinder 32 is installed on the top of the fixed base 31, and its free end extends vertically outward to the outside of the mounting base 10 and is fixedly connected to the corresponding mating plate 11. The cylinder signal generator 33 is fixedly installed on the top of the fixed base 31 and located beside the telescopic cylinder 32.

[0046] In the above scheme, in the initial state, the entire cable docking auxiliary device is installed in place, the drive motor 21 of the drive assembly 20 is in standby state, and all components are in their initial positions. The fixing base 31 is placed vertically inside the mounting base 10, with its middle part threadedly connected to the corresponding screw 22, and its bottom slidably connected to the bottom wall inside the mounting base 10.

[0047] When the drive motor 21 starts, it drives the two screws 22 to rotate synchronously through the connecting sleeve 23. Since the middle part of the fixed seat 31 is threadedly connected to the screw 22 and the bottom is slidably connected to the inner bottom wall of the mounting base 10, the fixed seat 31 moves along the width direction of the notch 101 (i.e., perpendicular to the top of the mounting base 10) under the action of the rotation of the screws 22. This achieves precise position adjustment of the docking plate 11 in the horizontal direction. As the fixed seat 31 moves, it drives the telescopic cylinder 32 and the cylinder signal generator 33 mounted on the fixed seat 31 to move together. After the fixed seat 31 moves to the appropriate position, the cylinder signal generator 33 provides power to the telescopic cylinder 32 according to the specific requirements of the cable docking, causing the free end of the telescopic cylinder 32 to extend or retract. The extension or retraction of the free end of the telescopic cylinder 32 will cause the docking plate 11 fixedly connected to it to rise or fall, achieving precise position adjustment of the docking plate 11 in the vertical direction. By precisely adjusting the docking plate 11 in both the horizontal and vertical directions, the ends of the two cables can be accurately connected, thus improving the accuracy of cable connection.

[0048] The constraint assembly 40 includes a guide sleeve 41, two pressing plates 45, two springs 42, a sliding sleeve 43, and two push rods 44. The wide-diameter section of the stepped guide sleeve 41 is horizontally and coaxially disposed on the side of the mating plate 11 away from the center of the mounting base 10. The kick surface of the guide sleeve 41 has two through holes 411 mirror-imaged, and the length direction of the two through holes 411 extends toward the plate surface of the corresponding pressing plate 45. The two pressing plates 45 are mirror-imaged disposed inside the guide sleeve 41, and one end of each pressing plate 45 is hinged to the kick surface of the guide sleeve 41, and their opposite ends extend toward the axis of the guide sleeve 41. Two springs 42 are respectively disposed between the two pressing plates 45 and the inner wall of the guide sleeve 41, and are located on the side of the wide diameter section of the guide sleeve 41 facing its narrow diameter section. One end of each spring 42 is fixedly connected to the side of the corresponding pressing plate 45 near the narrow diameter section of the guide sleeve 41, and the other end is fixedly connected to the inner wall of the guide sleeve 41. A sliding sleeve 43 is disposed on the periphery of the narrow diameter section of the guide sleeve 41 and slides along its axial length. One end of each push rod 44 is fixedly connected to the end of the sliding sleeve 43 near the kick surface of the guide sleeve 41, and the other end is close to or away from the corresponding pressing plate 45 along the corresponding through hole 411.

[0049] In the above scheme, the wide-diameter section of the guide sleeve 41 is fixedly connected to the side of the docking plate 11 away from the center of the mounting base 10. When the cable passes through the guide sleeve 41, the circumference of the cable will press against the end of the pressing plate 45, spreading the two pressing plates 45 apart so that the ends of the two pressing plates 45 contact the circumference of the cable. During this process, the spring 42 connected to the pressing plate 45 and the guide sleeve 41 is also spread apart by the cable. Due to the reaction force of the spring 42, the end of the pressing plate 45 will make interference contact with the circumference of the cable, locking the cable between the ends of the two pressing plates 45. The sliding sleeve 43 slides along the axial length of the narrow-diameter section of the guide sleeve 41, driving the push rod 44 to pass through the wide-diameter section of the guide sleeve 41 and abut against the circumference of the pressing plate 45, spreading the pressing plate 45 apart again, thereby separating the end of the pressing plate 45 from the cable, thus facilitating the cable's separation from the docking auxiliary device and improving the cable docking efficiency.

[0050] The narrow diameter section of the guide sleeve 41 is provided with an external thread 412, and the inner wall of the sliding sleeve 43 is recessed with an internal thread 431. The internal thread 431 and the external thread 412 are threadedly engaged, and the pitch of the external thread 412 is smaller than the pitch of the internal thread 431.

[0051] In the above scheme, in the initial state, the narrow-diameter section of the sliding sleeve 43 and the guide sleeve 41 are connected by threads to prevent the sliding sleeve 43 from separating from the guide sleeve 41. When the cable passes through the guide sleeve 41 and completes the connection, the internal thread 431 of the sliding sleeve 43 has completed the thread engagement with the external thread 412 of the narrow-diameter section and continues to feed towards the side of the pressing plate 45. During this process, since the pitch of the external thread 412 is smaller than the pitch of the internal thread 431, the contact mode between the sliding sleeve 43 and the guide sleeve 41 changes to sliding contact. And since the sliding sleeve 43 and the guide sleeve 41 cannot rotate on their own, the sliding sleeve 43 is restricted to the end position of the external thread 412 of the narrow-diameter section. The operator only needs to slide the sliding sleeve 43 further towards the side of the pressing plate 45 to open the pressing plate 45 again, thereby releasing the locking state of the cable and completing the disconnection of the cable from the connection auxiliary device, thus improving the efficiency of the cable connection operation.

[0052] The cross-sectional profile of the aperture 111 is approximately elliptical. The cross-sectional profile of the first aperture 111 with an approximately elliptical structure has a major axis and a minor axis. The major axis provides more room for movement, allowing the cable some offset and sway when passing through the docking plate 11, while the minor axis acts as a radial constraint, ensuring that the cable does not completely detach from the axis of the docking plate 11, avoiding docking failure due to cable shape mismatch, and reducing damage to the cable docking part.

[0053] The various embodiments in this specification are described in a progressive manner. For the same or similar parts between the various embodiments, please refer to each other. Each embodiment focuses on describing the differences from other embodiments.

Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
