Description

Technical Field

[0001] The utility model belongs to the technical field of live-line robots, and in particular relates to a pruning tool based on live-line operation scenarios. Background Art

[0002] Tree branches too close to overhead lines can cause power outages and even accidents, resulting in significant economic losses. Distribution lines typically operate at voltage levels of 10kV and below. The Electric Power Facility Protection Regulations stipulate that the electrical safety distance for 10kV conductors under maximum wind deflection is 1.5m. Tree branches too close to the lines are often the tips of thin, densely packed branches, and distributed across different areas of the line.

[0004] Most existing pruning tools require manual operation, requiring technicians working with live wires to use conventional pruning tools. This poses a risk of electric shock if people come close to high-voltage cables. Machine-operated pruning tools, on the other hand, are mostly shears, requiring precise, sequential pruning of tangled branches. This is inefficient and can only prune small branches, making them inefficient for larger, thicker branches. Summary of the Invention

[0038] The present invention will be further explained below with reference to the accompanying drawings.

[0050] The pruning mechanism includes a sprocket 15, which is arranged at one end of the load-bearing frame 13. The lower part of the sprocket 15 is driven and connected to the driving end of the drive motor 16. The drive motor 16 is connected to the lower part of the load-bearing frame 13. The drive motor 16 is electrically connected to the battery 12. The sprocket 15 is connected to the chain 7 for transmission. The chain 7 is provided with a blade, and the chain 7 is attached to the knife plate 8.

[0051] The upper portion of the blade 8 is in contact with a locking plate 5 , which is detachably connected to the upper housing 11 ;

[0052] The locking plate 5 is provided with a locking mechanism 6, which includes a knob cover 602, which is in contact with the locking plate 5, and a knob handle 601 is provided on the knob cover 602, and a cam locking nut 603 is provided at the lower end of the knob handle 601;

[0053] A slide groove is provided on the blade 8, and a locking stud 18 is provided in the slide groove. The other end of the locking stud 18 is connected to the upper shell 11, and the cam locking nut 603 is bolted to the locking stud 18;

[0054] The cam locking nut 603 is also in contact with the expansion slider 19, and the expansion slider 19 is slidably connected in the limiting groove 111, which is provided on the upper housing 11;

[0055] The expansion slider 19 is also connected to a movable column 113 via a connecting block 112, and the connecting block 112 is slidably connected to the connecting rod;

[0056] The connecting rod is connected to both sides of the limiting groove 111 , and a spring is disposed at one end thereof. The movable column 113 is connected to a limiting hole provided on the blade 8 .

[0057] The oil pumping mechanism includes an oil pump 17, which is arranged on the load-bearing frame 13. One end of the oil pump 17 is connected to the oil pot 9 through an oil suction pipe 21, and the oil pot 9 is connected to the lower shell 10. The other end of the oil pump 17 is connected to the blade 8 through an oil outlet pipe 20.

[0058] A sliding groove is provided on the periphery of the blade plate 8 , and the chain 7 is slidably connected to the sliding groove. The sliding groove is connected to an oil filling hole, which is provided on the blade plate 8 and connected to the oil outlet pipe 20 .

[0059] How it works:

[0060] like Figure 1 As shown, the docking tray 1 is detachably connected to the robotic arm, and the movement of the entire tool is achieved through the movement of the robotic arm;

[0061] like Figure 2 As shown, the control chamber integrates a control board and a wifi communication module, which is powered by a battery 12. When the robotic arm sends an instruction to perform pruning operations, the control board receives it through the communication module, and then controls the drive motor 16 to start and perform pruning. The control board can be a common tool motor drive control board.

[0062] It is worth noting here that a power switch 4 is provided on the cover plate 3. When in use, the power switch 4 is turned on. Whether or not to perform pruning operation is determined according to the signal sent by the robot arm. When the robot arm sends the pruning operation signal, the controller controls the drive motor 16 to work, driving the sprocket 15 to rotate, and then driving the chain 7 to rotate. That is, the entire tool does not need to be kept powered on all the time, but is turned on and off by the power switch 4, which plays the role of a main switch. When not in use, the power switch 4 is turned off and the entire tool is not powered on, which can save more electricity.

[0063] like Figure 5 As shown, for the pruning mechanism, after the driving motor 16 is started, the sprocket 15 is driven to rotate, and the sprocket 15 engages with the chain 7 and rotates in the sliding groove on the periphery of the blade 8. The chain 7 is equipped with a blade, thereby cutting the branches;

[0064] like Figure 6 and 7 As shown, since the chain will be damaged due to friction during cutting, in order to reduce friction and increase the service life of the chain 7, an oil filling hole is opened on the sliding groove ( Figure 6 The outer hole, Figure 6 The inner hole is for installing the movable column 113), and oil is pumped into the oil filling hole by the oil pump 17. The oil flows through the sliding groove to the chain 7 to lubricate the chain 7;

[0065] like Figure 8 As shown, in order to adjust the tightness of the chain 7 and prevent accidents, by rotating the knob handle 601 provided on the knob cover 602, a cam locking nut 603 is provided below the knob handle 601, which drives the cam locking nut 603 to move on the locking stud 18. The rotation of the cam locking nut 603 causes the cam to contact and squeeze the expansion slider 19, causing the expansion slider 19 to move.

[0066] like Figure 9 As shown, the movement of the expansion slider 19 in the limit groove 111 drives the connecting block 112 to move on the connecting rod (the connecting rod and the spring are not shown in the figure. It can be understood that the limit groove is divided into two parts, inner and outer. The connecting rod is connected to the bottom of the outer limit groove, and the connecting block 112 moves on it. One end of the outer limit groove contacts the spring, which can push the connecting block 112 to reset). The connecting block 112 drives the movement of the moving column 113, and the moving column is embedded in the knife plate 8. Therefore, the knife plate 8 moves, and the movement of the knife plate 8 squeezes the chain 7, thereby realizing the adjustment of the tightness of the chain 7.

[0067] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
