[0052] To facilitate understanding of the present application, the present application will be described more fully below with reference to the accompanying drawings. The accompanying drawings provide embodiments of the present application. However, the present application may be implemented in many different forms and is not limited to the embodiments described herein.

[0054] It should be noted that when an element is considered to be "connected" to another element, it can be directly connected to the other element or connected to the other element through an intermediate element. In the following embodiments, "connection" should be understood as "electrical connection", "communication connection", etc., if the connected circuits, modules, units, etc. can transmit electrical signals or data to each other.

[0055] When used herein, the singular forms "a", "an", and "the" may also include the plural forms, unless the context clearly indicates otherwise. It should also be understood that the terms "include / comprise" or "have" and the like specify the presence of stated features, integers, steps, operations, components, parts, or combinations thereof, but do not preclude the possibility of the presence or addition of one or more other features, integers, steps, operations, components, parts, or combinations thereof.

[0056] Connectors are frequently used in distribution network operations and maintenance. Currently, the most common crimping method involves hydraulic or electric crimping pliers, which require multiple crimping operations to complete a single connector. This process typically involves the use of gloves, requiring operators to hold the crimping pliers or hoist them for crimping. This entire process is subject to numerous limitations, including the operating environment, tools, sequence, and quality. Consequently, a crimping device is needed to ensure ease and stability throughout the entire process.

[0057] Based on this, an embodiment of the present application provides an electrically controlled crimping device for a connecting tube on an overhead conductor, which can improve the convenience of the crimping operation.

[0058] Figure 1 The present invention provides an electrically controlled crimping device for connecting pipes on overhead conductors. Figure 2 Shown Figure 1It is understood that, Figure 1 In order to illustrate more structures, some structures are indicated by dotted lines, but they actually represent the real objects.

[0059] See Figure 1 and Figure 2 The electrically controlled crimping device 100 for connecting pipes on overhead conductors provided in an embodiment of the present application includes a working bucket 10, a support frame 20, a crimping mechanism 30, and a control unit (not shown in the figure). The working bucket 10 is mounted on a boom truck; the support frame 20 is mounted on the working bucket 10; the crimping mechanism 30 is mounted on the end of the support frame 20 away from the working bucket 10. The crimping mechanism 30 includes a base 31 and a crimping clamp 32. The crimping clamp 32 is movable on the base 31 along a first direction F1. The base 31 is used to install the connecting pipe L so that the connecting pipe L is located within the jaws of the crimping clamp 32 and the overhead conductor passes through the connecting pipe L. The control unit is used to receive crimping instructions to control the crimping clamp 32 to crimp various parts of the connecting pipe L along the first direction F1; the first direction F1 is parallel to the axial direction of the connecting pipe L. The support frame 20 is fixed to the opening of the working bucket 10.

[0060] It should be noted that, in this embodiment, the crimping pliers 32 may be hydraulic pliers, while in other embodiments, the crimping pliers 32 may be voltage pliers. The base 31 may be an integrated structure or a split structure, which may be configured specifically according to actual conditions. The control unit includes a drive control board S1 and a crimping control board (shown in the following figure), and the crimping instruction includes the moving distance and crimping pressure of the crimping pliers 32. The drive control board S1 controls the movement of the crimping pliers 32 according to the moving distance of the crimping pliers 32 in the crimping instruction. The crimping control board controls the jaws of the crimping pliers 32 to crimp the connecting tube L and the overhead conductor according to the crimping pressure of the crimping pliers 32 in the crimping instruction.

[0061] During bypass or maintenance work, the operator stands in the work bucket 10 and uses a boom truck to raise the work bucket 10 to the vicinity of the overhead conductor. First, the operator uses a stripper to strip the wire sheath of the overhead conductor at the work location. Then, the operator uses an inter-column splitting tool to tighten the overhead conductor. The operator uses a cutter to cut the stripped section of the conductor. Then, the operator uses a clamping rod to clamp the conductor and insert it into the two ends of the connecting tube L, and then crimps it.

[0062] In this embodiment, by providing a support frame 20 to support and fix the crimping mechanism 30, manual hand-held crimping equipment can be eliminated, reducing the intensity of operation. By providing the crimping mechanism 30 including a base 31 and a crimping pliers 32, the connecting tube L is manually installed on the base 31, the overhead wire passes through the connecting tube L, and the connecting tube L is located in the jaws of the crimping pliers 32, preparing for the crimping operation. By providing the crimping pliers 32 to be movable along the first direction F1, the control unit receives the crimping instruction, controls the crimping pliers 32 to move and crimp the various parts of the connecting tube L along the first direction F1 according to the crimping instruction. In this way, the electrically controlled crimping pliers 32 can automatically crimp multiple times to complete the crimping work of an entire connecting tube L, greatly reducing the labor intensity and improving the convenience of the crimping operation.

[0063] Continue reading Figure 2 , and combined with Figure 3 , Figure 3 Shown Figure 1 Schematic diagram of the back structure of the crimping mechanism. Figure 3 In order to illustrate more structures, some structures are indicated by dotted lines, but they actually represent the real objects.

[0064] In some embodiments, the crimping mechanism 30 further includes a linear module 33 connected to the base 31 and the support frame 20 , and the crimping pliers 32 are connected to a slider 332 of the linear module 33 to enable the crimping pliers 32 to reciprocate along the first direction F1 .

[0065] Specifically, the linear module 33 includes a guide rail 331, a slider 332, a drive motor 333, a lead screw 334, a coupling 335, a drive control board S1, and a battery K. The drive motor 333 is connected to the lead screw 334 via the coupling 335. A lead screw transmission is provided between the lead screw 334 and the slider 332. The drive motor 333 rotates the lead screw 334 and converts the rotational motion into linear motion via the slider 332, enabling the slider 332 to move linearly along the guide rail 331 in a first direction F1. By connecting the guide rail 331 of the linear module 33 to the base 31 and the support frame 20, the support frame 20 supports the linear module 33 and the structure connected to the linear module 33. By setting the crimping pliers 32 to be connected to the slider 332 of the linear module 33, the crimping pliers 32 can reciprocate along the first direction F1 and automatically crimp the various parts of the connecting tube L, thereby replacing manual hand-held movement of the crimping pliers 32 and reducing labor intensity.

[0066] Continue reading Figure 2In some embodiments, the seat body 31 includes two fixed seats 311 and a movable seat 312 opposite to each other, the two fixed seats 311 are connected to the support frame 20, and the movable seat 312 is connected between the two fixed seats 311; wherein, the movable seat 312 is used to clamp one end of the connecting pipe L, and one of the fixed seats 311 is used to clamp the other end of the connecting pipe L; the movable seat 312 is configured to be able to adjust and lock the position to match the length of the connecting pipe L.

[0067] Specifically, in this embodiment, two fixed seats 311 are bolted to opposite ends of a guide rail 331 of the linear module 33. The guide rail 331 is connected to the support frame 20, so that the support frame 20 supports the guide rail 331 and the fixed seats 311 connected thereto. The two fixed seats 311 are opposed to each other along a first direction F1, and a guide rod 34 extending in the first direction F1 is connected between the two fixed seats 311. Multiple guide rods 34 may be provided (e.g., two or three), and the guide rods 34 pass through the movable seat 312, enabling the movable seat 312 to move along the first direction F1 and adjust its position. Furthermore, in this embodiment, a movable latch can be provided on the movable seat 312 and multiple pin holes can be provided on the guide rod 34 to facilitate locking the position of the movable seat 312. In other embodiments, a movable latch can be provided on a structure connected to the movable seat 312, and multiple pin holes or notches can be provided on a structural rod parallel to the guide rod 34 to facilitate locking the position of the movable seat 312. The movable seat 312 is provided for clamping one end of the connecting tube L, and one of the fixed seats 311 is provided for clamping the other end of the connecting tube L. In this way, the position of the movable seat 312 can be manually adjusted and locked according to the connecting tubes L of different specifications (different lengths), and the connecting tubes L can be quickly installed, thereby improving the adaptability of the electric-controlled crimping device 100.

[0068] Continue reading Figure 2 and Figure 3 In some embodiments, the crimping mechanism 30 further includes two clamping members 35 and two rotating members 36; a clamping member 35 and a rotating member 36 are installed on each of the movable seat 312 and one of the fixed seats 311, and the rotating member 36 is connected to the corresponding clamping member 35; wherein the clamping member 35 has an opening; the rotating member 36 is configured to be able to rotate around a second direction to adjust the direction of the opening of the clamping member 35 so that the connecting tube L is clamped into the opening of the clamping member 35, and the second direction is the axial direction of the connecting tube L.

[0069] Specifically, a curved slideway is provided on the surface of the movable seat 312. A sliding shaft is connected between the movable seat 312 and one of the rotating members 36. The rotating member 36 rotates on the curved slideway of the movable seat 312 via the sliding shaft, so that the rotating member 36 can rotate about the second direction. A curved slideway is also provided on one of the fixed seats 311. A sliding shaft is connected between the fixed seat 311 and another of the rotating members 36. The rotating member 36 rotates on the curved slideway of the fixed seat 311 via the sliding shaft, so that the rotating member 36 can rotate about the second direction.

[0070] It should be noted that, in this embodiment, both the fixed seat 311 and the movable seat 312 are provided with arc-shaped avoidance openings, and each avoidance opening is arranged in the horizontal direction. A circular arc-shaped chuck 361 is provided at one end of the rotating member 36, wherein the chuck 361 of one rotating member 36 is partially sleeved within the avoidance opening of the movable seat 312, and the chuck 361 of the other rotating member 36 is partially sleeved within the avoidance opening of one of the fixed seats 311. The chuck member 35 is clamped into the chuck 361 of the rotating member 36. Since the crimping pliers 32 are located between the movable seat 312 and one of the fixed seats 311, the jaws of the crimping pliers 32 are opened in the horizontal direction. When manually installing the connecting tube L, the rotating member 36 is manually rotated to make the opening of the chuck member 35 face the horizontal direction, so that the connecting tube L can pass through the jaws of the crimping pliers 32 and be clamped into the opening of the chuck member 35, thereby avoiding interference with the crimping pliers 32 and facilitating the installation of the connecting tube L. The overhead wire then passes through the various avoidance openings, the opening of the clamp 361 of the rotating member 36, and the opening of the clamp member 35, and penetrates into the connecting tube L. Thereafter, the rotating member 36 is rotated to face the opening of the clamp member 35 upward to prevent the connecting tube L and the overhead wire from coming out in the horizontal direction.

[0071] For further information, see Figure 3 A movable positioning rod 37 is provided between the two fixed seats 311, and the positioning rod 37 passes through the rotating member 36; wherein the rotating member 36 connected to the movable seat 312 is configured to be locked on the positioning rod 37 in the first direction F1. In this embodiment, the end of each rotating member 36 away from the clamping member 35 passes through the connected positioning rod 37, and a plurality of notches are provided on the positioning rod 37. For the rotating member 36 connected to the movable seat 312, the end away from the clamping member 35 is connected to a movable pin. After manually adjusting the position of the movable seat 312, the movable pin adjacent to the rotating member 36 is inserted into the corresponding notch of the positioning rod 37, so that the rotating member 36 and the movable seat 312 can be locked in the first direction F1, thereby preventing the movable seat 312 from sliding along the first direction F1 during the installation of the connecting tube L and the overhead conductor, thereby improving the stability of the electric-controlled crimping device 100.

[0072] For further information, see Figure 3Each fixed seat 311 is provided with two vertically opposed fixing clips 311a. During the rotation of the rotating member 36, the two ends of the positioning rod 37 can be engaged with the two fixing clips 311a aligned along the first direction F1. In this embodiment, each fixed seat 311 is provided with two vertically opposed fixing clips 311a, each having a clamping opening. During operation, the positioning rod 37 is pushed upward, and the two ends of the positioning rod 37 are engaged with the fixing clips 311a of the two fixed seats 311. At this time, the opening of the clamping member 35 is facing horizontally, facilitating the installation of the connecting tube L and the insertion of the overhead conductors. After the connecting tube L and the overhead conductor are installed, the positioning rod 37 is pushed downward, and the two ends of the positioning rod 37 are clamped into the fixing clamps 311a of the two fixing seats 311 to change the opening state of the clamping head 35. This can prevent the connecting tube L and the overhead conductor from falling out in the horizontal direction, provide a guarantee for the stability of the crimping process, and improve the efficiency of the crimping operation.

[0073] Continue reading Figure 2 and Figure 3 , and combined with Figures 4 to 6 , Figure 4 Shown Figure 2 Schematic diagram of the exploded structure of part of the crimping mechanism, Figure 5 Shown Figure 2 A cross-sectional view of part of the crimping mechanism. Figure 6 A schematic diagram of the exploded structure of the clamping member in this embodiment is shown.

[0074] In some embodiments, the chuck member 35 includes a movable chuck sleeve 351 and a fixed chuck sleeve 352. The movable chuck sleeve 351 is mounted on the fixed chuck sleeve 352, and each movable chuck sleeve 351 is detachably connected to a corresponding rotating member 36. Both the movable chuck sleeve 351 and the fixed chuck sleeve 352 are provided with openings, and the rotation of the movable chuck sleeve 351 opens or closes the openings of the fixed chuck sleeve 352. Furthermore, the crimping mechanism 30 includes two guide sleeves M, each of which is detachably connected to the chuck member 35 to guide the direction of passage of the overhead conductor.

[0075] Specifically, a sleeve S is bolted to each of the movable seat 312 and one of the fixed seats 311, and each sleeve S is positioned within a corresponding avoidance opening. The sleeve S has an opening, and the opening of the sleeve S is arranged horizontally. During the installation of the chuck member 35 and the guide sleeve M, the trumpet-shaped guide sleeve M is first inserted into the opening of the sleeve S, with one end of the guide sleeve M extending out of the sleeve S. The chuck fixed sleeve 352 is partially inserted into the guide sleeve M, and the chuck movable sleeve 351 is inserted over the chuck fixed sleeve 352 and the sleeve S. The chuck 361 of the rotating member 36 is then inserted over the chuck movable sleeve 351. The chuck movable sleeve 351 is secured to the corresponding rotating member 36 via a latch. This allows the chuck member 35 and the guide sleeve M to be detachable. Furthermore, before the electrically controlled crimping device 100 is launched, the matching chuck member 35 and guide sleeve M can be quickly replaced based on the type of overhead conductor.

[0076] When installing the connecting pipe L, the rotating member 36 is manually rotated to make the opening of the chuck movable sleeve 351 coincide with the opening of the chuck fixed sleeve 352, so that the connecting pipe L is easily inserted. Figure 2 As shown. Then, the overhead conductor is guided by the guide sleeve M. After the connecting tube L and the overhead conductor are installed, the rotating member 36 is manually rotated to displace the opening of the chuck movable sleeve 351 and the opening of the chuck fixed sleeve 352, as shown. Figure 7 In this way, the opening of the clamping sleeve 352 is opened or closed by using the movable clamping sleeve 351, which facilitates the installation of the connecting tube L and prevents the connecting tube L and the overhead conductor from falling out, thereby helping to improve the stability of the crimping process. After all crimping operations are completed, the crimping mechanism 30 can be quickly separated from the connecting tube L by operating the rotating member 36 and the clamping member 35.

[0077] Continue reading Figure 3 In some embodiments, the electrically controlled crimping device 100 further includes a position sensor 38 disposed on the crimping pliers 32 for detecting the movement of the crimping pliers 32. Specifically, the position sensor 38 is in communication with the drive control board S1. By providing the position sensor 38 to detect the real-time position of the crimping pliers 32, the drive control board S1 controls the movement of the crimping pliers 32. This ensures uniform crimping of the connecting tube L and the overhead conductor, improving crimping quality and reliability.

[0078] Continue reading Figure 2 Furthermore, the electrically controlled crimping device 100 also includes a pressure sensor 39, located on the base 31, for detecting the crimping pressure of the crimping pliers 32. Specifically, the pressure sensor 39 is in communication with a crimping control board (shown in the following figures). By providing the pressure sensor 39 to detect the crimping pressure of the crimping pliers 32, the crimping control board determines whether the crimping is in place, thereby improving crimping quality, ensuring a more reliable and consistent crimping result.

[0079] Furthermore, the electrically controlled crimping device 100 further includes a camera (not shown) mounted on the base 31 for capturing real-time images of the crimping pliers 32 crimping the connecting tube L to determine the crimping quality. Specifically, the camera can be communicatively connected to a mobile terminal. By capturing real-time images of the crimping pliers 32 crimping the connecting tube L, the crimping quality can be visually and clearly observed, thereby improving the crimping quality.

[0080] See Figure 8 , Figure 8 Shown Figure 1 A schematic diagram of the structure of an electrically controlled crimping device from one perspective. In some embodiments, the support frame 20 is configured as an insulating frame; the support frame 20 includes multiple support rods 21, multiple insulating rods 22, and multiple adjustment members 23. The multiple support rods 21 are mounted on the work bucket 10, and each support rod 21 is provided with an adjustment member 23 and an insulating rod 22. The adjustment member 23 is used to adjust the insulation length of the insulating rod 22 relative to the portion extending from the support rod 21.

[0081] It should be noted that compared to the traditional method of performing the crimping operation using gloves, which poses a high safety risk to the operator, this embodiment configures the support frame 20 as an insulating frame to insulate the crimping mechanism 30 from the human body, reducing the risk of electric shock to the operator. Furthermore, due to the heavy weight of the crimping mechanism 30, the support frame 20 and the crimping mechanism 30 are installed on the work bucket 10 together, with the support frame 20 extending outside the work bucket 10. The insulation length of the support frame 20 is then adjusted. In this way, the support frame 20 is installed in steps, reducing the installation difficulty. In other embodiments, the support frame 20 can be a one-piece support structure, which can be provided with multiple support points on the work bucket 10.

[0082] In this embodiment, the support frame 20 includes two support rods 21, two insulating rods 22, and two adjustment members 23. Each support rod 21, insulating rod 22, and adjustment member 23 corresponds to the other. The support rods 21 are mounted on the sidewalls of the working bucket 10, and the angle between the support rods 21 and the working bucket 10 is adjustable to achieve optimal support. The insulating rods 22 are connected to the linear module 33 of the crimping mechanism 30. The adjustment members 23 are located at the end of the support rods 21 away from the working bucket 10. Each adjustment member 23 includes two pulleys and a fastener, with a gap between the two pulleys and staggered arrangement. The fasteners can be clamps. When installing the crimping mechanism 30, the insulating rod 22 connected to the crimping mechanism 30 is inserted into the gap between the two pulleys of the adjustment member 23, so that the two pulleys are on different sides of the insulating rod 22. By pushing the insulating rod 22, the insulating length of the insulating rod 22 relative to the support rod 21 is adjusted to a predetermined length. The insulating rod 22 is then secured with fasteners to ensure a stable support frame 20 structure. In this way, the crimping mechanism 30 and the operator can be effectively insulated, electric shock can be avoided, and the risk of crimping operation can be reduced. In addition, through the adjustment function of the adjustment member 23, the support frame 20 can be installed in steps, which reduces the installation difficulty and improves the installation efficiency.

[0083] Continue reading Figure 1 , and combined with Figure 9 , Figure 9 Shown Figure 1 Schematic diagram of the structure within the working bucket. In some embodiments, the crimping pliers 32 are hydraulic pliers. The electrically controlled crimping device 100 further includes a hydraulic system located within the working bucket 10 and connected to the crimping pliers 32 via an oil pipeline. The hydraulic system includes a fuel tank (not shown), a solenoid valve 41, and a booster 42. The solenoid valve 41 is installed between the fuel tank output port and the booster 42 to control the pressure increase and pressure reduction of the booster 42, thereby opening and closing the crimping pliers 32.

[0084] In this embodiment, the crimping pliers 32 are hydraulic pliers. A toolbox 40 is mounted on the inner wall of the work bucket 10, housing a hydraulic system. The hydraulic system comprises a fuel tank, a solenoid valve 41, and a booster 42. It also includes a crimping control board S2 and a battery K. The crimping control board S2 is electrically connected to the solenoid valve 41, and the battery K provides power to the crimping control board S2 and the solenoid valve 41. The solenoid valve 41 is installed between the fuel tank's outlet and the booster 42. The crimping control board S2 controls the switching of the solenoid valve 41 to control the pressure increase and pressure reduction of the booster 42, opening and closing the crimping pliers 32. This also increases the hydraulic pressure to the desired crimping pressure, improving the crimping effect. Furthermore, compared to hydraulic systems that utilize a hydraulic pump and require a separate high-power power supply within the work bucket 10, this embodiment utilizes the battery K to power the booster 42, thereby increasing the hydraulic power source, making it more convenient and practical. In other embodiments, the crimping pliers 32 may be rechargeable integrated crimping pliers, for example, DC lithium battery integrated crimping pliers, which is convenient for installation and improves the portability of the entire electric-controlled crimping device.

[0085] In some embodiments, see Figure 10 In this embodiment, the crimping pliers 32 adopts a single-sided crimping method. The crimping pliers 32 crimps the connecting tube L and the overhead wire by moving the lower pressure block upward. In this embodiment, in order to prevent the connecting tube L from arching and deforming during the crimping process, each fixed seat 311 is provided with a movable seat 3111 and a base 3112 connected to each other. The movable seat 3111 can be slidably connected to the base 3112 in the vertical direction. The two opposite bases 3112 are respectively connected to the linear module 33. A guide rod 34 and a positioning rod 37 are connected between the two opposite movable seats 3111. A clamping member 35 is installed on one of the movable seats 3111. Specifically, when the lower pressure block of the crimping pliers 32 moves upward, a clamping member 35 is subjected to an upward force, which naturally drives the two movable seats 3111 to move upward. This can prevent the connecting tube L from arching at the crimping point and keep the connecting tube L as a straight tube as possible after crimping, thereby improving consistency and aesthetics. After one crimping is completed, when the lower pressing block of the crimping pliers 32 moves downward, a clamping piece 35 falls naturally, thereby driving the two movable seats 3111 to descend to the initial position, and when the movable seats 3111 are in the initial position, the connecting tube L is directed toward the middle of the opening of the crimping pliers 32, making it convenient to take and place the connecting tube L.

[0086] In other embodiments, the crimping pliers 32 may adopt a bilateral crimping method, with the upper and lower crimping blocks of the crimping pliers 32 both crimping toward the connecting tube L and the overhead conductor. In this way, the connecting tube L can be kept as straight as possible after crimping, improving consistency and aesthetics.

[0087] Continue reading Figure 2In some embodiments, the crimping pliers 32 are detachably connected to the slider 332 of the linear module 33. Specifically, the slider 332 of the linear module 33 is bolted to a mounting base G. The mounting base G is provided with a movable clamp, within which the crimping pliers 32 are mounted. This allows the clamp to be removed or installed during movement, allowing the jaw size of the crimping pliers 32 to match the diameter of the connecting pipe L, thereby improving the adaptability of the electrically controlled crimping device 100.

[0088] Continue reading Figure 1 、 Figure 2 and Figure 9 In some embodiments, the electric-controlled crimping device 100 further includes a remote controller 50, which is communicatively connected to the control unit. The remote controller 50 is used to input crimping instructions and send them to the control unit. Specifically, a control chip is installed in the remote controller 50, and a corresponding crimping control program is installed in the control chip. The remote controller 50 is wirelessly connected to the drive control board S1, the crimping control board S2, and each sensor. After the operator installs the connecting tube L and the overhead wire on the crimping mechanism 30, the operator operates the remote controller 50 to issue a crimping control instruction to control the movement of the crimping pliers 32 and crimp the connecting tube L at a predetermined position. In this way, fully automatic crimping can be achieved, which greatly reduces the labor intensity of the crimping operation, improves the convenience of operation, and reduces the risk of operation.
