Description

Technical Field

[0001] The present invention relates to the technical field of manipulator equipment, and in particular to a lightweight auxiliary manipulator arm for live-line operation of an insulated short pole of a distribution network. Background Art

[0002] During live operations on distribution networks, a boom lift will lift personnel to the bottom of overhead cables, where they will use hand-held insulating short rods to perform cable stripping and wiring operations. The hand-held insulating short rods can be used to avoid direct contact between personnel and cables, thereby improving personnel safety.

[0003] The existing insulating short rod operation will also be carried out by a robotic arm. The robotic arm is used to reduce the workload of personnel and realize the lightweight of personnel work. The robotic arm and the lifting cabin of the articulated arm lift are fixed.

The position of the robotic arm is limited by the space of the lifting cabin of the articulated arm lift, and the operating range of the robotic arm is limited. Therefore, the lifting cabin of the articulated arm lift needs to be accurately moved to the bottom of the processed line.

[0037] In the embodiment of the present disclosure, the external spiral teeth of the second electric worm 201 are meshed and connected with the middle tooth block of the upper circular shaft turntable 202, the lower end of the middle electric lifting screw 203 is rotatably connected with the inner bottom of the outer sliding tube 103, the lower end gear of the middle electric lifting screw 203 is meshed and connected with the main shaft gear of the side drive motor 104, and the external thread of the middle electric lifting screw 203 drives the side lifting frame 2 to move up and down, and the side lifting frame 2 moves vertically along the outer sliding tube 103. The side lifting frame 2 performs a height lifting operation on the upper short rod connecting tube 3 and the insulating short rod. After the upper short rod connecting tube 3 is tilted, the insulating short rod can also contact and align with the top of the insulating short rod in the middle of the main frame 1 to connect the line.

[0038] In the embodiment of the present disclosure, the gear of the main shaft of the upper driving motor 303 is meshed and connected with the outer tooth block of the upper short rod connecting tube 3, the tail end cylindrical sliding of the upper short rod connecting tube 3 is provided with an outer slide 308, the tail end of the outer support spring 307 is fixed to the outer slide 308, and the middle two sides of the outer slide 308 are provided with vertical middle slide grooves 309, the upper part of the middle circular shaft connecting platform 105 is rotated with a lower connecting rotating frame 301, the third electric worm 302 is meshed and connected with the worm wheel of the upper circular shaft of the middle circular shaft connecting platform 105, the upper part of the upper circular shaft turntable 202 is rotated with a lower connecting rotating frame 301, the third electric worm 302 is meshed and connected with the worm wheel of the upper circular shaft of the upper circular shaft turntable 202, the spiral teeth of the third electric worm 302 are meshed and the circular shaft worm wheel of the middle circular shaft connecting platform 105 or the upper circular shaft turntable 202 is tilted and rotated in a circumferential direction, so as to realize the inclination angle setting of the upper short rod connecting tube 3 and the insulating short rod.

[0039] In the disclosed embodiment, the external connecting slide column 405 and the middle slide groove 309 are slidably connected, and the middle slide groove 309 is inclined toward the side away from the upper short rod connecting tube 3. When the external connecting slide column 405 moves vertically, the middle slide groove 309 and the outer slide frame 308 move close to the upper short rod connecting tube 3, and the outer slide frame 308 moves to compress the external support spring 307, thereby increasing the supporting force of the external support spring 307 on the side fixing block 306, and increasing the clamping force of the side fixing block 306 on the middle insulating short rod, thereby further tightening the insulating short rod in advance.

[0040] Embodiment 2, based on embodiment 1, the main frame 1 can be set on a scissors lift, which supports the main frame 1 to increase its height. The main frame 1 is used with the scissors lift in passages that are inconvenient for vehicles to enter, thereby reducing dependence on articulated arm lifts and improving versatility.

[0041] The working principle of this embodiment: the lower part of the main frame 1 is an inverted U-shaped structure, the main frame 1 and the lifting cabin of the boom lift are vertically slid and connected and fixed, and then the boom lift lift lifts the main frame 1 to the bottom of the line that needs to be processed, and an insulating short rod is slid into the inner side of the upper short rod connecting tube 3, and the insulating short rod is slid between the upper lifting frame 4 and the opposite ring frame 401 at the same time. Different types of insulating short rods can be installed on the upper part of the main frame 1 and the side lifting frame 2. An insulating short rod with a stripping function is installed in the middle part of the main frame 1, and an insulating short rod with a wire clamp is installed on the side lifting frame 2 to connect the line after stripping. The first electric worm 101, the second electric worm 201, the third electric worm 302, the upper drive motor 303, and the upper electric lifting screw 304 are all connected to the control of the main frame 1 The module is electrically connected to the air start, and the personnel perform various operations through the control module. The motor drives the first electric worm 101 to start rotating, and the spiral teeth on the outside of the first electric worm 101 mesh with the side tooth groove extension bar 102 to drive the side tooth groove extension bar 102 to move horizontally in the axial direction. The side tooth groove extension bar 102 moves toward the outside of the main frame 1, and the side lifting frame 2 extends and moves toward both sides along with the side tooth groove extension bar 102, thereby expanding the use and matching distance of the upper short rod connecting tube 3 in the center of the main frame 1 and the insulating short rods connected to the upper short rod connecting tubes 3 on both sides, and expanding the working range of the line operation, so that the operating range is not limited by the width of the lifting cabin of the articulated arm lift, reducing the alignment requirements for the accuracy of the line operation position, and better compatible with the error offset of the position;

[0042] The upper short rod connecting tube 3 above the main frame 1 and the side lifting frame 2 can be tilted and rotated in the circumferential direction through the helical tooth meshing of the third electric worm 302 and the circular shaft worm gear of the middle circular shaft connecting platform 105 or the upper circular shaft turntable 202. The side driving motor 104 realizes synchronous rotation through the gear meshing of the gear of the middle electric lifting screw 203. The external thread of the middle electric lifting screw 203 drives the side lifting frame 2 to move axially. The side lifting frame 2 moves vertically along the outer sliding tube 103. The lifting and lowering of the side lifting frame 2 supplements the height of the upper short rod connecting tube 3 and the insulating short rod. The upper short rod connecting tube 3 is insulated after being tilted. The short insulating rod can also contact the top of the insulating short rod in the middle of the main frame 1, ensuring that the insulating short rod in the middle of the main frame 1 and the insulating short rods of the side lifting frames 2 on both sides are connected to the line at one position. The upper drive motor 303 drives the upper short rod connecting cylinder 3 to rotate in the circumferential direction through gear meshing. The upper short rod connecting cylinder 3 and the insulating short rod rotate in the circumferential direction to realize the rotation and tightening of the insulating short rod to the wire clamp bolt, eliminating the need for manual operation by personnel. Personnel are on the ground to perform high-altitude line connection operations, and the personnel are in a safer position, further preventing accidental electric shock, and also reducing the screening of people who are afraid of heights, and reducing the requirements for practitioners;

[0043] The upper electric lifting screw 304 is driven to rotate by the motor, and the external thread of the upper electric lifting screw 304 guides the upper lifting frame 4 to move axially vertically. The upper and lower lifting frames 4 and the opposite ring frame 401 are in contact with the upper and lower cross-sections of the lower control pipe fittings of the clamping type insulating short rod. The upper lifting frame 4 and the opposite ring frame 401 push the control pipe fittings up and down by fitting with the cross-sections of the control pipe fittings, so as to realize the connection and pushing and subsequent tightening operations between the top hook of the clamping type insulating short rod and the line clamp. The upper lifting frame 4 is longer than the control pipe fitting. During the upward movement of the upper lifting frame 4, the upper lifting frame 4, the opposite ring frame 401 and the outer slide frame 308 move upward synchronously, and the outer connecting slide column 405 is connected by The middle slide groove 309 guides the outer slide 308 to move close to the upper short rod connecting tube 3, and the outer slide 308 compresses the outer support spring 307. The compressed outer support spring 307 increases the supporting force of the side fixing block 306, and the clamping force of the side fixing block 306 on the middle insulating short rod is increased. The clamping position of the insulating short rod is first controlled to avoid the situation where the insulating short rod moves synchronously with the control pipe due to insufficient tightening. The opposite ring frame 401 supports the movement of the side connecting slide column 402 and the closing of the upper lifting frame 4 through the side support spring 403. The spacing distance is expanded by pulling the opposite ring frame 401 away from the upper lifting frame 4, which facilitates the removal and separation operation of the inner insulating short rod.
