For example, the crimping operation environment, crimping tools, crimping sequence and crimping quality, etc. Now a crimping device is needed throughout the entire crimping process to ensure the simplicity and stability of crimping.

[0021] 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.

[0022] Figure 1 An electrically controlled crimping device for a connecting tube on an overhead conductor provided in an embodiment of the present application is shown. Figure 2 Shows Figure 1 The front structural diagram of the crimping mechanism. It can be understood that Figure 1 In order to illustrate more structures, some structures are indicated by dotted lines, but they actually represent real objects.

[0023] See also Figure 1 and Figure 2The electrically controlled crimping device 100 for connecting pipes on overhead conductors provided in the embodiment of the present application comprises 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 arranged on a boom truck; the support frame 20 is arranged on the working bucket 10; the crimping mechanism 30 is arranged at one end of the support frame 20 away from the working bucket 10, and the crimping mechanism 30 comprises a seat body 31 and a crimping clamp 32, the crimping clamp 32 is movably arranged on the seat body 31 along a first direction F1, the seat body 31 is used to install the connecting pipe L, so that the connecting pipe L is located in 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 at the opening of the working bucket 10.

[0024] It should be noted that, in the present embodiment, the crimping pliers 32 may adopt hydraulic pliers, and in other embodiments, the crimping pliers 32 may adopt voltage pliers. The seat body 31 may adopt an integrated structure, or a split structure, which may be specifically configured 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 joint tube L and the overhead wire according to the crimping pressure of the crimping pliers 32 in the crimping instruction.

[0025] During bypass operation or maintenance operation, the operator stands in the operation bucket 10 and raises the operation bucket 10 to the vicinity of the overhead wire by means of a boom truck. First, the wire skin of the overhead wire at the operation site is stripped with a stripper, and then the overhead wire is tightened with an inter-column cutting tool, and the stripped wire section is cut with a cutter, and then the wire is clamped with a clamp rod and inserted into the two ends of the joint tube L respectively, and then crimping is performed.

[0026] In this embodiment, by setting a support frame 20 to support and fix the crimping mechanism 30, manual hand-held crimping equipment can be eliminated and the operation intensity can be reduced. By setting the crimping mechanism 30 to include a seat body 31 and a crimping pliers 32, the connecting tube L is manually installed on the seat body 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, in preparation for the crimping operation. By setting 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 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 a whole connecting tube L, which greatly reduces the labor intensity and improves the convenience of the crimping operation.

[0027] Continue reading Figure 2 , and combined with Figure 3 , Figure 3Shows 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 real objects.

[0028] 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 .

[0029] 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, a battery K and other components. The drive motor 333 is connected to the lead screw 334 through the coupling 335, and the lead screw 334 and the slider 332 are driven by the lead screw. The drive motor 333 drives the lead screw 334 to rotate, and converts the rotational motion into linear motion through the slider 332, so that the slider 332 can move linearly along the first direction F1 on the guide rail 331. The guide rail 331 of the linear module 33 is connected to the seat body 31 and the support frame 20, so that 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.

[0030] Continue reading Figure 2 In 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 tube L, and one of the fixed seats 311 is used to clamp the other end of the connecting tube L; the movable seat 312 is configured to be able to adjust and lock the position to match the length of the connecting tube L.

[0031] Specifically, in this embodiment, two fixed seats 311 are fixed to the two ends of the guide rail 331 of the linear module 33 by bolts, and 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 seat 311 connected to the guide rail 331. The two fixed seats 311 are opposite to each other along the first direction F1, and a guide rod 34 extending in the first direction F1 is connected between the two fixed seats 311. The guide rod 34 can be provided with multiple (for example, two or three, etc.), and the guide rod 34 passes through the moving seat 312, so that the moving seat 312 can move along the first direction F1 and adjust its own position. Further, in this embodiment, a movable latch can be provided on the moving seat 312, and multiple pin holes can be provided on the guide rod 34, so as to lock the position of the moving seat 312; in other embodiments, a movable latch can also be provided on the structure connected to the moving seat 312, and multiple pin holes or notches can be provided on the structural rod parallel to the guide rod 34, so as to lock the position of the moving 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 used 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 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.

[0032] Continue reading Figure 2 and Figure 3 In some embodiments, the crimping mechanism 30 also includes two clamping members 35 and two rotating members 36; a clamping member 35 and a rotating member 36 are installed on 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.

[0033] Specifically, an arc-shaped slideway is provided on the surface of the movable seat 312, and a sliding shaft is connected between the movable seat 312 and one of the rotating members 36. The rotating member 36 rotates on the arc-shaped slideway of the movable seat 312 via the sliding shaft, so that the rotating member 36 can rotate around the second direction. An arc-shaped slideway is also provided on one of the fixed seats 311, and a sliding shaft is connected between the fixed seat 311 and another of the rotating members 36. The rotating member 36 rotates on the arc-shaped slideway of the fixed seat 311 via the sliding shaft, so that the rotating member 36 can rotate around the second direction.

[0034] It should be noted that, in the present 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. An arc-shaped chuck 361 is arranged at one end of the rotating member 36, wherein the chuck 361 of one rotating member 36 is partially sleeved in the avoidance opening of the movable seat 312, and the chuck 361 of the other rotating member 36 is partially sleeved in 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 opening of the chuck member 35 is opened in the horizontal direction by manually rotating the rotating member 36, 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, so as to avoid the interference of the crimping pliers 32 and facilitate the installation of the connecting tube L. Then the overhead wire passes through each avoidance opening, 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. After that, the rotating member 36 is rotated to face the opening of the clamp member 35 upward, which can prevent the connecting tube L and the overhead wire from coming out in the horizontal direction.

[0035] 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, one 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, one end away from the clamping member 35 is connected to a movable latch. After manually adjusting the position of the movable seat 312, the movable latch 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, so as to avoid the sliding of the movable seat 312 along the first direction F1 during the installation of the connecting tube L and the overhead wire, thereby improving the stability of the electric-controlled crimping device 100.

[0036] For further information, see Figure 3, each fixed seat 311 is provided with two fixed clips 311a opposite to each other in the vertical direction, and during the rotation of the rotating member 36, the two ends of the positioning rod 37 can be clamped on the two fixed clips 311a aligned along the first direction F1. In this embodiment, each fixed seat 311 is provided with two fixed clips 311a opposite to each other in the vertical direction, and the fixed clips 311a have a clamping opening. In the actual operation process, the positioning rod 37 is pushed upward, and the two ends of the positioning rod 37 are clamped into the fixed clips 311a of the two fixed seats 311. At this time, the opening of the clamping member 35 faces the horizontal direction, which is convenient for installing the connecting tube L and inserting the overhead wire. After the connecting tube L and the overhead wire are installed, the positioning rod 37 is pushed downward, and the two ends of the positioning rod 37 are inserted 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 wire from escaping in the horizontal direction, provide a guarantee for the stability of the crimping process, and improve the efficiency of the crimping operation.

[0037] Continue reading Figure 2 and Figure 3 , and combined with Figures 4 to 6 , Figure 4 Shows Figure 2 Schematic diagram of the exploded structure of part of the crimping mechanism. Figure 5 Shows Figure 2 A cross-sectional view of some structures in the crimping mechanism. Figure 6 A schematic diagram of the exploded structure of the clamping member in this embodiment is shown.

[0038] In some embodiments, the clamping member 35 includes a clamping movable sleeve 351 and a clamping fixed sleeve 352; the clamping movable sleeve 351 is sleeved on the clamping fixed sleeve 352, and each clamping movable sleeve 351 is detachably connected to the corresponding rotating member 36; the clamping movable sleeve 351 and the clamping fixed sleeve 352 are both provided with openings, and the opening of the clamping fixed sleeve 352 is opened or closed during the rotation of the clamping movable sleeve 351. Further, the crimping mechanism 30 also includes two guide sleeves M, each of which is detachably connected to the clamping member 35 to guide the penetration direction of the overhead wire.

[0039] Specifically, a sleeve S is installed on the movable seat 312 and one of the fixed seats 311 respectively by bolts, and each sleeve S is located in the corresponding avoidance opening, and the sleeve S has an opening, and the opening of the sleeve S is arranged in the horizontal direction. In the process of installing the chuck member 35 and the guide sleeve M, the trumpet-shaped guide sleeve M is first sleeved in the opening of the sleeve S, and one end of the guide sleeve M extends out of the sleeve S, the chuck fixed sleeve 352 is partially sleeved on the guide sleeve M, and the chuck movable sleeve 351 is sleeved on the chuck fixed sleeve 352 and the sleeve S, and then the chuck 361 of the rotating member 36 is sleeved on the outside of the chuck movable sleeve 351, and the chuck movable sleeve 351 and the corresponding rotating member 36 are fixed by a latch, so that the chuck member 35 and the guide sleeve M can be detachable, and before the electric-controlled crimping device 100 is lifted into the air, the matching chuck member 35 and the guide sleeve M can be quickly replaced according to the type of the overhead wire.

[0040] When installing the connecting pipe L, the rotating member 36 is manually rotated to make the opening of the chuck movable sleeve 351 overlap with the opening of the chuck fixed sleeve 352, so that the connecting pipe L is easily inserted. Figure 2 As shown. Then, the guide sleeve M is used to guide the penetration direction of the overhead wire. After the joint tube L and the overhead wire are installed, the rotating member 36 is manually rotated to displace the opening of the clamp movable sleeve 351 and the opening of the clamp fixed sleeve 352, as shown. Figure 7 In this way, the opening of the clamping head fixed sleeve 352 is opened or closed by using the clamping head movable sleeve 351, which facilitates the installation of the connecting tube L and prevents the connecting tube L and the overhead wire from falling out, which helps to improve the stability of the crimping process, and after all the crimping operations are completed, the crimping mechanism 32 can quickly detach from the connecting tube L by operating the rotating member 36 and the clamping head member 35.

[0041] Continue reading Figure 3 In some embodiments, the electric-controlled crimping device 100 further includes: a position sensor 38, which is disposed on the crimping pliers 32 and is used to detect the moving position of the crimping pliers 32. Specifically, the position sensor 38 is in communication connection with the drive control board S1. The position sensor 38 is provided to detect the real-time position of the crimping pliers 32, so that the drive control board S1 controls the moving process of the crimping pliers 32. In this way, the joint tube L and the overhead wire are uniformly crimped, thereby improving the crimping quality and reliability.

[0042] Continue reading Figure 2 Furthermore, the electric-controlled crimping device 100 further includes: a pressure sensor 39, which is arranged on the seat body 31 and is used to detect the crimping pressure of the crimping pliers 32. Specifically, the pressure sensor 39 is connected to the crimping control board (shown in the following figure) in communication. By setting 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 the crimping quality, making the crimping effect more reliable, and maintaining consistency.

[0043] Furthermore, the electric-controlled crimping device 100 further includes: a camera (not shown in the figure), which is arranged on the base 31 and is used to collect real-time images of the crimping pliers 32 crimping the butt joint tube L to determine the crimping effect. Specifically, the camera and the mobile terminal can be connected in communication, and by setting the camera to collect real-time images of the crimping pliers 32 crimping the butt joint tube L, the crimping effect can be observed intuitively and clearly, thereby improving the crimping quality.

[0044] See also Figure 8 , Figure 8 Shows Figure 1 A schematic diagram of the structure of the electric-controlled crimping device at a certain viewing angle. In some embodiments, the support frame 20 is configured as an insulating frame; the support frame 20 includes a plurality of support rods 21, a plurality of insulating rods 22, and a plurality of adjusting members 23. The plurality of support rods 21 are arranged on the working bucket 10, and each support rod 21 is provided with an adjusting member 23 and an insulating rod 22, and the adjusting member 23 is used to adjust the insulating length of the insulating rod 22 relative to the extended portion of the support rod 21.

[0045] It should be noted that compared with the traditional method of completing the crimping operation by the glove method, the safety risk of the operator is high. In this embodiment, by configuring the support frame 20 as an insulating frame, the crimping mechanism 30 and the human body can be insulated, thereby reducing the risk of electric shock to the operator. In addition, since the crimping mechanism 30 is heavy, the support frame 20 is installed on the working bucket 10 together with the crimping mechanism 30, and the support frame 20 extends out of the working bucket 10, and then the insulating length of the support frame 20 is adjusted. In this way, the support frame 20 is installed in steps to reduce the difficulty of installation. In other embodiments, the support frame 20 can be an integrated support structure, and the integrated support structure can be provided with multiple support points on the working bucket 10.

[0046] In this embodiment, the support frame 20 includes two support rods 21, two insulating rods 22 and two adjusting members 23, and the support rods 21, the insulating rods 22 and the adjusting members 23 correspond to each other. The support rods 21 are mounted on the side wall of the working bucket 10, and the angle between the support rods 21 and the working bucket 10 can be adjusted to achieve a better support effect. The insulating rods 22 are connected to the linear module 33 of the crimping mechanism 30. The adjusting member 23 is arranged at one end of the support rod 21 away from the working bucket 10. Each adjusting member 23 includes two pulleys and a fastener, and there is a gap between the two pulleys, and they are staggered. The fastener can be a clamp. 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 adjusting member 23, so that the two pulleys are located 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 reach a predetermined length, and the insulating rod 22 is fixed by the fastener to make the support frame 20 structure stable. In this way, the crimping mechanism 30 and the operator can be effectively insulated to avoid electric shock and reduce the risk of crimping operation. In addition, through the adjustment function of the adjustment member 23, it is convenient to install the support frame 20 in steps, reduce the difficulty of installation, and improve installation efficiency.

[0047] Continue reading Figure 1 , and combined with Fig. 9 , Fig. 9 Shows Figure 1 Schematic diagram of the structure of the working bucket. In some embodiments, the crimping pliers 32 are hydraulic pliers; the electric-controlled crimping device 100 further includes: a hydraulic system, which is arranged in the working bucket 10, and the hydraulic system and the crimping pliers 32 are connected through an oil pipeline; the hydraulic system includes an oil tank (not shown in the figure), a solenoid valve 41 and a booster 42, and the solenoid valve 41 is installed between the output port of the oil tank and the booster 42 to control the pressure increase and pressure relief of the booster 42 to realize the opening and closing of the crimping pliers 32.

[0048] In this embodiment, the crimping pliers 32 adopt hydraulic pliers. A tool box 40 is hung on the inner wall of the working bucket 10, and the tool box 40 is provided with a hydraulic system. The hydraulic system includes an oil tank, a solenoid valve 41 and a supercharger 42, and 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 for the crimping control board S2 and the solenoid valve 41. The solenoid valve 41 is installed between the output port of the oil tank and the supercharger 42. The solenoid valve 41 is reversing by the crimping control board S2 to control the pressure increase and pressure relief of the supercharger 42, so as to realize the opening and closing of the crimping pliers 32, and the hydraulic pressure can also be increased to the required crimping pressure to improve the crimping effect. In addition, compared with the hydraulic system using a hydraulic pump, a high-power power supply is additionally provided in the working bucket 10. In this embodiment, the battery K is used to power the supercharger 42, and the supercharger 42 is used to increase the hydraulic power source, which is 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.

[0049] In some embodiments, see Fig.10 In this embodiment, the crimping pliers 32 adopts a single-sided crimping method, and the crimping pliers 32 crimps the connecting tube L and the overhead wire by moving the lower pressing 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 to include a movable seat 3111 and a base 3112 connected to each other, and the movable seat 3111 can be slidably connected to the base 3112 in the vertical direction, and the two opposite bases 3112 are respectively connected to the linear module 33, and a guide rod 34 and a positioning rod 37 are connected between the two opposite movable seats 3111, and a clamping member 35 is installed on one of the movable seats 3111. Specifically, during the upward movement of the lower pressing block of the crimping pliers 32, a clamping member 35 is subjected to an upward force, which naturally drives the two movable seats 3111 to move upward, thereby avoiding the situation that the connecting tube L arches at the crimping position, and trying to keep the connecting tube L after crimping into a straight tube, 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, so that the connecting tube L is convenient to take and place.

[0050] In other embodiments, the crimping pliers 32 may adopt a bilateral crimping method, and the upper and lower crimping blocks of the crimping pliers 32 are crimped toward the connecting tube L and the overhead wire. In this way, the connecting tube L after crimping can be kept as a straight tube as much as possible to improve consistency and aesthetics.

[0051] 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 connected to a mounting seat G through bolts, and a movable clamp is provided on the mounting seat G, and the crimping pliers 32 is installed in the clamp. In this way, during the movement of the clamp, a specific type of crimping pliers 32 can be removed or installed, so that the jaw size of the crimping pliers 32 matches the diameter of the connecting tube L, thereby improving the adaptability of the electric-controlled crimping device 100.

[0052] Continue reading Figure 1 , Figure 2 and Fig. 9 In some embodiments, the electric-controlled crimping device 100 further includes a remote controller 50, which is communicatively connected to the control unit, and 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, respectively. 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 operation risk.
