Description

[0001] The invention relates to the technical field of power equipment, and in particular to a tree-cutting robot. Background Art
[0002] In the power system, the power wiring process often crosses mountains and ridges. There are often a large number of trees under the line corridor or a large number of trees up to tens of meters high are often planted near the line, which makes it difficult to ensure sufficient clearance safety distance between the line and the trees, which has a great impact on the safe and stable operation of the line. In order to reduce the impact of trees on the safe operation of the line, it is necessary to cut down the trees.

[0053] As Figure 1 shown, this embodiment provides a tree-felling robot, which includes a mobile vehicle 1, a lifting platform 2 and a chainsaw assembly. The mobile vehicle 1 includes wheels 11 and a vehicle body 12. The wheels 11 are rotatably arranged on the lower side of the vehicle body 12. The rolling of the wheels 11 can drive the movement of the vehicle body 12. The wheels 11 are driven to rotate by a first motor, and the first motor is equipped with a remote controller. The start and stop of the first motor are controlled through the remote controller, so as to control the travel and stop of the mobile vehicle 1. The lifting platform 2 is arranged on the vehicle body 12, and the lifting tabletop 25 of the lifting platform 2 can move in the direction perpendicular to the bearing surface of the vehicle body 12. The chainsaw assembly is arranged on the lifting tabletop 25, and the chainsaw assembly is configured to trim trees. By arranging the chainsaw assembly on the mobile vehicle 1, the mobile vehicle 1 carries the chainsaw assembly for position transfer, saving manpower; by arranging the lifting platform 2, the height of the chainsaw assembly can be adjusted in a timely manner, so that the cutting position of the chainsaw assembly on the tree can be flexibly adjusted according to the shielding situation of the tree on the transmission line.
[0054] Preferably, in combination with Figure 1 and Figure 2As shown, the lifting platform 2 is of a scissor structure and is lifted by an electric hydraulic jack 23. Specifically, the lifting platform 2 includes a lifting tabletop 25 and two sets of support frames arranged at intervals. The support frames include a plurality of connecting rods 21, and the plurality of connecting rods 21 are connected in a scissor manner between the lifting tabletop 25 and the vehicle body 12. The two sets of support frames are connected by a fixed shaft 22. The fixed end and the driving end of the electric hydraulic jack 23 are respectively connected to the vehicle body 12 and the fixed shaft 22. When the driving end of the electric hydraulic jack 23 moves, it drives the fixed shaft 22 to lift, thereby realizing the height adjustment of the lifting tabletop 25, and further adjusting the height of the chain saw assembly arranged on the lifting tabletop 25. The electric hydraulic jack 23 is equipped with a remote control, and the remote control is signal-connected to the electric hydraulic jack 23 to control the operation of the electric hydraulic jack 23 through the remote control.
[0055] Preferably, as Figure 1 and Figure 2 shown, rollers 24 are arranged at the connection points of the connecting rod 21 with the lifting tabletop 25 and the vehicle body 12, and the movement of the connecting rod 21 is made smoother by the rolling of the rollers 24. Corresponding grooves are provided on the lifting tabletop 25 and the vehicle body 12, and the rollers 24 are limited in the above grooves to prevent the connecting rod 21 from moving randomly and making the lifting platform 2 unstable.
[0056] Furthermore, as Figure 1 shown, the mobile vehicle 1 further includes an auxiliary climbing assembly 13. The auxiliary climbing assembly 13 is connected to the front side of the vehicle body 12 and is configured to assist the wheels 11 in climbing over obstacles, so that the mobile vehicle 1 is more adaptable to the uneven road surface in the mountain forest.

The two sets of triangular wheels 131 are connected by a connecting shaft 132. The rolling direction of the triangular wheels 131 is the same as the rolling direction of the wheels 11, and the bottom rolling surface of the triangular wheels 131 is higher than the bottom rolling surface of the wheels 11, so that the triangular wheels 131 can climb on higher places and make the mobile vehicle 1 more suitable for climbing upwards. The two ends of the fixed arm 133 are respectively connected to the vehicle body 12 and the connecting shaft 132 to connect the triangular wheels 131 to the vehicle body 12.
[0058] The auxiliary climbing assembly 13 further includes a third motor 135 for driving the triangular wheels 131 to rotate. In addition, the auxiliary climbing assembly 13 is also provided with a remote control, and the remote control is communicatively connected to the third motor 135 to control the start and stop of the third motor 135.
[0059] Preferably, a shock absorber 134 is provided at one end of the fixed arm 133 connected to the connecting shaft 132. The shock absorber 134 can reduce the vibration of the triangular wheels 131 and enable the chain saw assembly to maintain a relatively stable state. The shock absorber 134 is preferably a hydraulic shock absorber.

The first chainsaw assembly 4 further includes a first chainsaw 43. One end of the first chainsaw 43 is connected to the end of the support arm 42 away from the support column 41. The cutting edge of the first chainsaw 43 is arranged vertically to cut the tree in the vertical direction. The first chainsaw assembly 4 further includes a first electro-hydraulic strut 44. The fixed end and the driving end of the first electro-hydraulic strut 44 are respectively connected to the support column 41 and the support arm 42 to drive the support arm 42 to rotate around the support column 41, so that the first chainsaw 43 moves and cuts in the vertical plane.
[0061] Preferably, please continue to refer to Figure 1 , the first chainsaw assembly 4 further includes a second electro-hydraulic strut 45. The fixed end and the driving end of the second electro-hydraulic strut 45 are respectively connected to the first chainsaw 43 and the support arm 42 to drive the first chainsaw 43 to approach or move away from the support arm 42, thereby adjusting the distance that the first chainsaw 43 extends out of the vehicle body 12. During actual work, the distance that the first chainsaw 43 extends out of the vehicle body 12 can be flexibly adjusted according to the growth condition of the tree.
[0062] Further, the first chainsaw assembly 4 further includes a fourth motor 46. The fourth motor 46 is used to drive the first chainsaw 43 to rotate. Preferably, the fourth motor 46 is also equipped with a remote controller, and the start and stop of the fourth motor 46 can be remotely controlled by operating the remote controller.
[0063] Further, in combination with Figure 1 and Figures 5 - 7 , the chainsaw assembly further includes a second chainsaw assembly 5. The second chainsaw assembly 5 includes a support member 51 and a second chainsaw 52. The support member 51 is connected to the lifting table 25.

The two second chain saws 52 on both sides swing outwards and can form almost a straight line with the middle second chain saw 52, so that the three groups of second chain saws 52 form a larger cutting range. Preferably, the three second chain saws 52 are driven by a chain 53, and the chain 53 is connected to the gear shaft 521 of the second chain saw 52. The rotation of the gear shaft 521 can drive the cutting blade of the second chain saw 52 to rotate and cut.
