Description

Technical Field

[0001] The invention relates to the technical field of tree felling, and in particular to a light directional tree felling device. Background Art

[0002] There are many trees along the distribution network overhead lines, and there is often a risk of falling trees, which requires inspection personnel to go and clear obstacles. However, if there is a lack of detailed tree felling planning and preparation, and the distance between trees and power lines cannot be accurately judged, the trees may touch the power lines when they fall, causing power failures such as short circuits and tripping. Or during the tree felling process, if the felling direction is not accurately controlled or the direction of the branches falling is not controlled, the branches or trunks may touch the power lines, causing safety hazards.

[0003] There are many tree felling devices on the market suitable for the power industry. These devices are designed to improve the efficiency and safety of tree felling, especially when dealing with trees close to power lines. However, these devices also have some disadvantages. Manual felling with auxiliary tools is not reliable. During the manual felling process, if the contact point between the device and the tree slips, or the force point is below the center of gravity, the tree is easy to rebound or fall, which may cause the tree to lose control or even fall on the line, increasing the risk of electric shock;

[0004] Unsafe falling paths: Existing auxiliary methods (such as pushing with hands, pulling with ropes, etc.) may make workers close to the cutting blades and saws, which may cause accidental injuries. At the same time, falling trees may easily injure people around them.

[0005] Logging machinery is expensive. Although some advanced logging machinery can improve the efficiency of tree felling, the configuration of modules such as high-pressure pumps and water tanks will lead to high manufacturing costs and relatively high maintenance costs; Poor operability: Some logging machinery has a complex structure and is difficult to operate, requiring professional personnel to operate and maintain; Limited economic efficiency: Although some logging mechanisms have been successfully developed, they have not been well promoted and applied in the production process of forest operations due to constraints in economy, versatility, and reliability.

[0006] Certain auxiliary devices carry climbing operation risks. When clearing extremely high tree obstacles, if the method of climbing trees and tying insulating ropes to the trees is adopted, the branches above the trees may be thin and difficult to climb and tie, which increases the operation risks and affects work efficiency. Limited scope of application: some auxiliary devices may only be suitable for specific types of trees or trees of a specific height, and may not be effectively used for other types of trees or heights. Summary of the invention

[0007] In view of the above problems existing in the existing light directional tree felling device, the present invention is proposed.

The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0031] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0032] Example 1

[0033] Reference Figure 1-Figure 2, a light directional tree felling device is provided, comprising, a mounting frame 100, a top end of which is movably connected to a guide member 200;

[0034] The tree felling mechanism 300 is fixed on one side of the mounting frame 100;

[0035] The insulating rope is fixed on the guide 200, and the mounting frame 100 cooperates with the guide 200 to make the insulating rope sleeved on the outside of the trunk of the tree to be felled, and a triangular notch is cut at the end of the tree to be felled close to the power line, so that the tree-felling mechanism 300 corresponds to the notch. After the tree-felling mechanism 300 is activated, the notch of the tree to be felled is enlarged, and then the insulating rope is pulled to guide it to the specified direction.

[0036] Furthermore, the tree felling mechanism 300 includes a driving member 301 fixedly disposed on one side of the mounting frame 100, and an output end of the driving member 301 is connected to a resisting member 302; wherein the driving member 301 can push the resisting member 302 to move;

[0037] In this embodiment, the driving member 301 is preferably a hydraulic pump;

[0038] The output end of the driving member 301 is fixedly connected with the resisting member 302. When in use, the end of the resisting member 302 can be plugged into the notch, and the driving member 301 pushes the resisting member 302 to contact the notch, thereby enlarging the notch.

[0039] Furthermore, the abutment member 302 includes a fixed block 302a fixedly disposed at the end of the driving member 301, and the upper and lower surfaces of the fixed block 302a are connected to a rotating plate 302b;

[0040] The fixed block 302a gradually widens from the end to the end close to the driving member 301; an elastic member 303 is connected between the two sets of rotating plates 302b;

[0041] The rotating plate 302b is rotatably connected to the fixed block 302a. The surface of the rotating plate 302b is provided with a protective pattern. The cross section of the fixed block 302a is triangular. In this embodiment, the elastic member 303 is preferably a spring. The two ends of the elastic member 303 are respectively connected to the two groups of rotating plates 302b. Under the resistance of the elastic member 303, the opposite sides of the two groups of rotating plates 302b are both in contact with the surface of the fixed block 302a.

[0042] During use, the narrower end of the fixed block 302a is snapped into the notch of the tree to be felled, and the driving member 301 pushes the fixed block 302a to gradually penetrate deeper into the notch. During the movement of the fixed block 302a, the ends of the two groups of rotating plates 302b that are close to each other abut against the notch and increase. When the ends of the two groups that are far from each other enter the notch, the ends of the two groups of rotating plates 302b that are far from each other are squeezed and rotated. After the rotating plate 302b rotates, it squeezes the elastic member 303 to contract. After the elastic member 303 contracts, a reaction force is generated, and the rotating plate 302b further squeezes the tree to increase the notch. At this time, the tree can be pulled by the insulating rope to make the tree trunk fall in the specified direction.

[0043] By completing the binding of high branches on the ground without climbing the tree, it is possible to reduce the time and labor costs brought by climbing the tree and fixing the ropes. At the same time, through the pulling of the ropes, the safety hazard of the tree falling towards the line side is reduced, the operation efficiency of distribution tree felling is improved, the safe operation of power facilities and the life safety of operators are guaranteed, and the device is designed to be lightweight and convenient to carry and use.

[0044] Embodiment 2

[0045] Refer to Figure 1-Figure 2 This embodiment is different from the first embodiment in that it further includes a fixed clamping frame 400 fixedly arranged at one end of the mounting frame 100;

[0046] The guiding member 200 includes a fixed column 201 rotatably connected to the fixed clamping frame 400, and a long rod 202 is fixedly connected to the outside of the fixed column 201;

[0047] The mounting frame 100 is integrally in a "U" shape. A fixed clamping frame 400 is fixedly arranged at the top of one end of the mounting frame 100. The fixed clamping frame 400 is in a "U" shape, and the opening of the "U" shape faces the inside of the mounting frame 100. The fixed column 201 is clamped in the fixed clamping frame 400, and the fixed clamping frame 400 is provided with a through groove corresponding to the long rod 202, so that the long rod 202 can rotate freely with the fixed column 201 as the center.

[0048] Furthermore, a bayonet 203 is opened at the bottom of the long rod 202, and a card slot 101 corresponding to the bayonet 203 is opened at the end of the mounting frame 100 away from the fixed column 201; the long rod 202 is connected to the mounting frame 100 through the cooperation of the bayonet 203 and the card slot 101;

[0049] By pulling the end of the long rod 202 away from the fixed column 201, the bayonet 203 is snapped into the card slot 101, thereby connecting the long rod 202 to the other end of the mounting frame 100.

[0050] Furthermore, a round hole 204 is opened at the end of the long rod 202; the round hole 204 is located at the end of the long rod 202 away from the fixed column 201.

[0051] The remaining structures are the same as those in Embodiment 1.

[0052] Operation process: When in use, a lock is hung in the round hole 204, and an insulating rope is fixed on the lock. The insulating rope is pulled to make the bayonet 203 clamped in the clamping groove 101 and fixed. The mounting frame 100 is lifted upward to make the long rod 202 collide with the trunk to be felled, and the mounting frame 100 is continuously pushed to move, so that the long rod 202 rotates 90 degrees toward the inside of the mounting frame 100 with the bayonet 203 as the center of the circle. At this time, the fixed column 201 is separated from the fixed clamping frame 400, until the trunk to be felled enters the inside of the mounting frame 100, and the insulating rope is pulled to make the long rod 202 rotate and reset again. At this time, the fixed column 201 is driven to enter the fixed clamping frame 400 again. When the fixed column 201 is completely reset, the mounting frame 100 is pulled downward, and the trunk collided with the long rod 202 to make it rotate upward with the fixed column 201 as the center of the circle. At this time, the cable is sleeved on the outside of the tree to be felled;

[0053] After the cable is sleeved on the tree through the above operation, the tree felling mechanism 300 is matched with the notch, and the two cooperate to complete the felling of the tree.

[0056] The mounting frame 100 can be fixed on any rod-shaped object through the round tube 102, which is convenient for manual operation. Through the setting of the hook 500, when the insulating rope is fixed on the long rod 202, the insulating rope can be placed in the hook 500, and then the insulating rope can be guided to ensure the use effect of the device.

[0057] The rest of the structure is the same as that of Example 2.
