Description

Technical Field

[0001] The utility model relates to the technical field of tree felling auxiliary tools, in particular to a tree falling auxiliary tool for felling operations. Background Art

[0002] A common problem in the maintenance of 10kV overhead railway power lines is trees, commonly known as "green pests," growing on both sides of the overhead lines. These trees may pose a threat to the safe operation of the power lines. Since railway lines are usually long and green pests are widely distributed, coupled with limited maintenance personnel, felling operations become complicated and time-consuming.

[0003] To improve felling efficiency, reduce time and labor costs, and ensure worker safety, the industry is constantly seeking to innovate and improve existing felling tools. Currently, daily felling operations typically involve a team of three: one person climbs the tree and attaches the rope, one person pulls the rope from the ground to control the tree's fall, and a third person performs the actual felling.

[0004] Although some specialized rope threading tools exist in the prior art, such as a rope threading hook disclosed in Chinese Patent Publication No. CN219018301U, this tool is primarily used for linear rope threading operations. However, it lacks the function of effectively guiding, pushing, and pulling trees, and therefore has certain limitations in practical applications. This single-functional rope threading tool cannot meet the needs of felling operations in complex environments.

[0005] Therefore, in order to further improve the convenience of felling operations, we propose a tree-falling auxiliary tool for felling operations. Utility Model Content

[0006] The purpose of the utility model is to solve the shortcomings of the prior art such as lack of functions for effectively guiding, pushing and pulling trees, and single functionality, and to propose a tree-felling auxiliary tool for felling green trees.

[0007] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0008] Design a tree-felling auxiliary tool, comprising:

[0009] A bracket and a locking assembly mounted on the top end of the bracket;

[0010] As well as tree hooks and rope hooks;

[0011] The tail ends of the tree pulling hook and the rope threading hook are both formed with a connecting seat, and the connecting seat is connected and locked with the locking assembly;

[0012] The bottom end of the rope threading hook is connected to a bending rod, and a tree pushing opening is formed between the bending rod and the tree pulling hook.

[0013] Furthermore, the connecting seat is a rectangular structure, and a locking hole is provided on the side end of the connecting seat.

[0014] Furthermore, the locking assembly includes two plug holes opened on the top of the bracket, and the plug holes are plugged and adapted to the connecting seat;

[0015] A locking sleeve is slidably connected to the outer side of the bracket, and a through hole extending into the plug hole is opened on the end face of the bracket. A locking bead is movably connected to the through hole, and the locking bead is snap-fitted with the locking hole.

[0016] Furthermore, the inner side of the locking sleeve has a resisting portion that resists the locking bead, and the outer side of the bracket is also fixedly mounted with a convex ring, and a spring is connected between the convex ring and the resisting portion.

[0017] Furthermore, at least one expansion rod is detachably connected to the bottom of the bracket, and the expansion rod is connected to the bracket via a connecting structure.

[0018] Furthermore, the connection structure includes a threaded sleeve formed on the bracket and the bottom end of the expansion rod, and a threaded portion adapted to the threaded sleeve is formed on the top of the expansion rod.

[0019] Furthermore, the rope threading hook includes a U-shaped frame, with two openings in opposite directions at both ends of the U-shaped frame, and hook rods are hung at the two openings, and one end of the hook rod is rotatably connected to a connecting ring.

[0020] The utility model provides an auxiliary tool for felling trees during green felling operations, which has the following beneficial effects:

[0021] The utility model adopts three methods to control the falling direction of trees. First, the tree pulling hook can be used to pull the felled tree in the opposite direction of the power overhead line; secondly, the tree can be pushed away from the line through the tree pushing opening; when targeting large trees with a diameter of more than 20mm, a rope is tied at a high place using a rope hook, and the falling direction of the tree is controlled by pulling the subsequent rope. In this way, the falling direction of the tree pole can be controlled in a multifunctional manner during the felling process, ensuring the safety of the operation;

[0022] In addition, after using this auxiliary tool, only two people are needed in a team, one to fix the direction of the falling tree and the other to cut it down. This can save 30% of manpower and avoid the life safety risks when climbing trees, meeting the needs of felling operations for 10kV overhead power lines. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0029] Reference Figure 1-4 This is an embodiment of the present invention, which specifically discloses a tree-felling auxiliary tool, the tool comprising:

[0030] A bracket 1 and a locking assembly 2 installed on the top of the bracket 1;

[0031] As well as the tree pulling hook 3 and the rope threading hook 4, specifically, the tree pulling hook 3 described in this embodiment is a U-shaped structure, and its function is to pull the tree trunk, and the rope threading hook 4 is used to hang a rope on the tree trunk so as to control the guidance of the tree trunk through the rope later;

[0032] A connecting seat 5 is formed on the tail end of the tree pulling hook 3 and the rope threading hook 4, and the connecting seat 5 is connected and locked with the locking assembly 2;

[0033] The bottom end of the rope threading hook 4 is connected to a bending rod 41 , and a tree pushing opening 6 is formed between the bending rod 41 and the tree pulling hook 3 .

[0034] Specifically, in order to ensure the safety and efficiency of felling operations, the following three methods are used in this embodiment to control the direction of tree falling: first, the tree pulling hook 3 can be used to pull the felled tree in the opposite direction of the power overhead line; secondly, the tree can be pushed away from the line through the tree pushing opening 6; when targeting large trees with a diameter exceeding 20 mm, a rope hook 4 is used to tie a rope at a high place, and the subsequent rope is pulled to control the direction of the tree falling. In this way, during the felling process, multifunctional control of the falling direction of the tree support pole can be achieved, ensuring the safety of the operation.

[0035] In some embodiments, the connecting seat 5 in the present invention is a rectangular structure, and a locking hole 51 is provided on a side end of the connecting seat 5 .

[0036] On the basis of the above embodiment, the locking assembly 2 includes two plug holes 21 opened on the top of the bracket 1, and the plug holes 21 are plugged and adapted with the connecting seat 5;

[0037] A locking sleeve 22 is slidably connected to the outer side of the bracket 1 , and a through hole extending into the plug hole 21 is opened on the end face of the bracket 1 , and a locking bead 23 is movably connected to the through hole, and the locking bead 23 is snap-fitted with the locking hole 51 .

[0038] Specifically, the diameter of the through hole described in this embodiment is smaller than the diameter of the locking bead 23. Its design purpose is to prevent the locking bead 23 from falling downward along the inside of the through hole. At the same time, a part of the locking bead 23 protrudes from the through hole and is snapped into the inner side of the locking hole 51, thereby realizing the snap-on locking of the connecting seat 5. In addition, a locking hole 51 is provided on one side of the connecting seat 5 described in the utility model, and two locking beads 23 are provided, which are respectively used to snap into the two locking holes 51 on the connecting seat 5.

[0039] Furthermore, in the present invention, the inner side of the locking sleeve 22 has a resisting portion 24 that resists the locking bead 23 , and the outer side of the bracket 1 is also fixedly mounted with a convex ring 25 , and a spring 26 is connected between the convex ring 25 and the resisting portion 24 .

[0040] That is, in a normal state, the entire locking sleeve 22 moves forward under the resistance of the spring 26, and the resistance portion 24 on the locking sleeve 22 resists the locking bead 23 and moves toward the circular portion of the bracket 1, thereby achieving a locking connection with the locking hole 51 on the connecting seat 5;

[0041] When unlocking is required, the locking sleeve 22 is pulled backwards. At this time, the abutment portion 24 on the locking sleeve 22 is separated from the locking bead 23. Therefore, the locking bead 23 has a certain space to move radially along the bracket 1. In this state, the tree pulling hook 3 or the rope threading hook 4 can be pulled outwards to remove it.

[0042] That is to say, through the design of the locking component 2 in the utility model, the independent installation and disassembly of the tree pulling hook 3 and the rope threading hook 4 can be realized. At the same time, the disassembly and assembly can be carried out simply by pushing and pulling the locking sleeve 22. Through the independent and combined use of the tree pulling hook 3 and the rope threading hook 4, various functions such as hooking branches, pushing branches, and hanging ropes above can be realized.

[0043] Furthermore, in this embodiment, at least one expansion rod 7 is detachably connected to the bottom of the bracket 1 , and the expansion rod 7 is connected to the bracket 1 via a connecting structure.

[0044] Based on the above embodiments, the connection structure in the present invention includes a threaded sleeve 71 formed at the bottom end of the bracket 1 and the expansion rod 7, and a threaded portion 72 adapted to the threaded sleeve 71 is formed at the top of the expansion rod 7.

[0045] That is, in the present invention, the length of the bracket 1 can be changed by connecting a plurality of expansion rods 7, so that it can be adapted to the chopping operations at different heights, further improving the applicability of the tool.

[0046] It should be noted that, in this embodiment, the rope threading hook 4 includes a U-shaped frame 42, and two openings 43 are opened in two directions away from each other at both ends of the U-shaped frame 42. The two openings 43 are hung with hook rods 44, and one end of the hook rod 44 is rotatably connected to a connecting ring 45. The connecting ring 45 is used to drive the rope to move. Of course, the specific operating principle of the rope threading hook 4 has been disclosed in the prior art and will not be elaborated here.

[0047] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
