Description

Technical Field

[0001] The invention relates to the technical field of overhead power transmission line maintenance, and in particular to a tree-pulling auxiliary tool for obstacle removal operations. Background Art

[0002] The clearing of tree barriers in overhead power transmission line corridors is complicated by the complexity of the working environment. There are dangerous sources such as live lines, houses, and graves near tree barriers. If such tree barriers are allowed to fall to the side of the dangerous source when they are cut down, it will cause serious consequences such as power outages, damage to residents' property, and electric shocks to people. Therefore, the direction of the falling tree must be controlled. According to on-site statistics, the average clearing time for a single tree barrier that needs to be controlled by ropes is 7 minutes. The work is time-consuming and the workload is heavy, which makes the operation and maintenance personnel overwhelmed. For example: First, the process of workers climbing trees is cumbersome. The height of the trees to be felled is generally 10 to 15 meters. Workers need to use lifting plates or foot buckles, take safety precautions, and then climb to a suitable height to tie ropes. Due to the high climbing height and the harsh outdoor environment, the workers spend a lot of time and effort; second, there are tree branches that hinder workers when climbing trees. The trees to be felled generally grow for many years and have a large number of forked branches, which increases the difficulty and time of the operation; third, the tree obstacles where the ropes need to control the falling direction involve climbing up the tree, tying the ropes, and getting down the tree. This process is time-consuming and consumes a lot of physical strength of the operation and maintenance personnel, so that one tree obstacle point requires multiple working days to complete, resulting in the failure to clear the tree obstacles at other points in time, causing long-term hidden dangers on the line and affecting the safe operation of the line. Summary of the invention

[0003] In view of the deficiencies in the prior art, the present invention provides a tree-pulling auxiliary tool for obstacle removal operations, which solves the technical problems in the prior art that ropes are difficult to quickly tie to trees, the operating efficiency is low, and there are safety hazards.

[0022] It should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "set", "install", "connect", etc. should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0023] The following will be combined with the attached Figure 1-2 , the present invention is further described.

[0024] In an embodiment of the present invention, the tree-pulling auxiliary tool for obstacle removal operations includes: a rod body 1 and a rod head structure 2; the rod body 1 extends in the up and down directions; the rod head structure 2 is arranged at the end of the rod body 1, and the rod head structure 2 includes a first opening 205 and a second opening 206, the first opening 205 is arranged upward for supporting and lifting the knot, and the second opening 206 is arranged downward for hanging on the knot; wherein, under the action of external force, the rod body 1 links the first opening 205 and the second opening 206 to move in opposite directions in sequence.

[0025] Specifically, in the embodiments of the present invention, the time consumption can be reduced. In the process of clearing tree obstacles that need to control the direction, the average clearing time of a single tree obstacle that needs to be controlled by ropes to control the falling direction is shortened, which improves the work efficiency and reduces the risk of workers falling from heights. During operation, one end of the rope can be tied and sent to the appropriate height of the tree obstacle, and the knot can be pulled down from the other side and then tied and tightened to complete the binding, so as to achieve the purpose of controlling the falling direction of the tree obstacle with ropes, avoiding the need for workers to use lifting plates or foot buckles to climb trees to complete rope binding; the work is flexible and adaptable, and it is easy to carry on site. During the operation, the pole length can be adjusted according to the height of the tree obstacle.

[0026] Since the first opening 205 of the rod head structure 2 is set upward and the second opening 206 is set downward, the branch penetration rate is better and the branch hanging rate is lower, which has the advantage of tying the rope around the tree. The rod body 1 part is made of carbon fiber structure, which has high plasticity, is firm and reliable, and can ensure the overall weight. When lifting tools, it can effectively avoid problems such as breakage and cracking.

[0027] After using this auxiliary tool, the time for clearing obstacles on power transmission lines was reduced from about 7 minutes using the traditional method to 2.46 minutes, which reduced the working hours of operators and improved work efficiency. It has the advantages of strong applicability and simple operation, low cost, and production promotion value. It ensures the safety of operators to the greatest extent possible and reduces the risk of operators climbing trees during operations. It has good safety benefits, further ensures the safe and stable operation of power transmission equipment, and improves the production and operation efficiency of equipment.

[0028] By using this tool, the present invention reduces the time required for clearing a single tree from an average of 7 minutes to 2.46 minutes, achieving the expected goal of an average clearing time of less than 3 minutes for a single tree obstacle that requires a rope to control the falling direction, and also ensures the safety of the operators to the greatest extent possible, reducing the risk of falling from heights caused by climbing trees during the operation. In addition, the device also has the advantages of simple manufacturing, low cost, easy operation, safety and reliability, quick access, strong practicality, and small storage space.

[0029] like Figure 2 As shown, in one embodiment, the club head structure 2 further includes a solid rod body 201, one end of the solid rod body 201 is disposed on the shaft 1, and the other end thereof is first bent downward and then bent upward to form the second opening 206 and the first opening 205 one by one. Specifically, in order to deliver the knot into the tree obstacle and avoid getting hung on branches, the present embodiment adopts a solid rod body 201 with a diameter of 5 mm and a steel structure as the rod head; the 5 mm steel is cut into 24 cm short sections and curved by a machine tool; one end of the solid rod body 201 is connected to the rod body 1, and the other end is first bent downward to form a second opening 206 and then bent upward to form a first opening 205. The two openings share the same rod body, and the one-piece structure can make the structure simpler and does not require assembly; at the same time, the first opening 205 is set upward to facilitate the lifting of the knot, and the second opening 206 is set downward to avoid getting hung on branches when moving upward, and on the other hand, it is convenient to quickly pass through the knot and pull it to the corresponding position for binding, which is more flexible and simple to operate.

[0030] Preferably, Figure 2As shown, the solid rod body 201 includes a first section 202, a second section 203 and a third section 204 which are arranged in sequence at intervals. The first section 202 and the second section 203 are connected by an arc section 207, and the first opening 205 is formed therebetween. The second section 203 and the third section 204 are connected by another arc section 207, and the second opening 206 is formed therebetween. In this embodiment, since the arc section 207 of the rod head has the advantages of a higher branch penetration rate, a lower branch hanging rate, and is more convenient for ropes to be tied around trees, the rod head part selects an "N"-shaped structure, adopts a circular arc transition treatment method, and the process is smooth and the operation time of the binding process is shorter. Preferably, the projection of the first section 202 is located on the third section 204, so that the two are located on the same plane, thereby avoiding the situation of hanging branches when ascending or descending. Preferably, the two arc sections 207 are bent in opposite directions, and the radii of the two are equal.

[0031] like Figure 2 As shown, in one embodiment, the lengths of the first section 202, the second section 203 and the third section 204 are defined as L1, L2 and L3 respectively, satisfying: L1<L3; and / or L2<L3. Specifically, in order to suspend the first opening 205 and the second opening 206 relative to the shaft 1, this embodiment defines the lengths of the first section 202 and the second section 203 to be smaller than the length of the third section 204. On the one hand, it can prevent the shaft 1 from interfering with the expansion degree of the corresponding opening, which is conducive to the rapid passage or removal of the knot; on the other hand, it is convenient to quickly install the third section 204 on the shaft 1.

[0032] like Figure 1 , Figure 2 As shown, in one embodiment, the end of the third section 204 away from the second section 203 is screwed on the shaft 1. Specifically, for the convenience of storage, this embodiment uses a threaded connection between the third section 204 and the shaft 1 so that the third section 204 can be fixed or separated relative to the shaft 1; the end diameter of the shaft 1 is 8mm and is provided with a threaded interface. The shaft 1 and the head are threadedly connected, which has strong stability and does not fall off, which is conducive to the coordination of the overall appearance and the convenience of storage and transportation. Preferably, the length of the third section 204 extending into the shaft 1 is defined as D, which satisfies: D ≥ 20㎜.

[0033] like Figure 1As shown, in one embodiment, the end and / or middle of the shaft 1 is provided with a telescopic structure 3, and the telescopic structure 3 includes a plurality of tubes threadedly sleeved in sequence. Specifically, in order to facilitate the storage of the tool, the present embodiment provides a telescopic structure 3 at the shaft 1, and the telescopic structure 3 is a plurality of tubes threadedly sleeved. The length of the shaft 1 is adjusted by rotating the tubes forward and backward to change the length of the shaft 1. The threaded connection is positioned and the length of the shaft 1 can be adjusted according to the binding height of the rope on the tree barrier, which is convenient for on-site use. Preferably, at least one of the tubes is provided with a scale line for checking the telescopic length of the tube.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
