Description

Technical Field

[0001] The invention relates to the technical field of power distribution and maintenance, in particular to a tree pulling device and a power distribution and maintenance system. Background Art

[0002] There are often large-scale trees or vines growing around the distribution lines of 10kV medium-voltage lines. When the plants grow too fast and touch the distribution lines, long-term contact may cause single-phase short circuit grounding faults or even two-phase short circuits, causing the substation circuit breaker to trip and power outages, or even endanger personal safety. Therefore, in order to ensure a safe distance between the wires and the trees, tree clearance work needs to be carried out regularly during daily line maintenance. The reality is that when felling trees, in order to prevent the trees from falling and causing secondary damage to the wires, residential houses, cash crops, and on-site construction workers, the direction of the trees' fall needs to be controlled. To control the direction, some staff members need to climb up the trees to be felled and use ropes to fix and pull them.

[0003] The existing method of controlling the falling direction of felled trees is mainly: personnel climb up the trees and use ropes to fix the trees to be felled, and two personnel pull the two ends of the ropes to make the trees fall in a certain direction after the bottom of the trees are cut off, so as to prevent discharge between the wires and the fallen trees due to insufficient clearance.

[0004] In actual application, the existing method of controlling the falling direction of trees has disadvantages: personnel must climb up the trees to tie up the trimmed trees with traction ropes, and many risks arise in the climbing process, such as whether the trees can accommodate the personnel, whether it is convenient to wear safety belts during the climbing process, how to tie traction ropes for old and small trees, how to climb and tie ropes for small branches on tree branches, and so on.

[0005] Therefore, we propose a tree pulling device and power distribution maintenance system. Summary of the invention

[0029] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0030] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0031] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. 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.

[0032] Example 1, reference Figure 1-2, which is the first embodiment of the present invention, provides a tree pulling device, including a pulling assembly 100, including a covering member 101, a sealing member 102 movably arranged on the covering member 101, an extension member 103 fixedly arranged at the bottom of the covering member 101, and a blocking member 104 for limiting the covering member 101 and the sealing member 102.

[0033] Preferably, the covering member 101 is fixed to one end of the extension member 103 by bolts;

[0034] The covering member 101 is used to wrap trees. The staff moves the extension member 103 to move the tree into the covering member 101. After the tree is completely covered, the sealing member 102 is pulled to make the sealing member 102 close the covering member 101, so that the tree is completely covered by the covering member 101. After moving the extension member 103 again, the tree in the covering member 101 is tilted in the correct direction according to the actual situation. When cutting down trees or vines, they can fall in the correct and harmless direction.

[0035] Example 2, reference Figures 1 to 9 , which is the second embodiment of the present invention, provides a tree pulling device, including a covering member 101 including a first enclosure 101a and a second enclosure 101b, and a space Z for accommodating the entry of a tree is formed between the first enclosure 101a and the second enclosure 101b.

[0036] Preferably, the first enclosure 101a and the second enclosure 101b are fixedly connected, and a space Z formed between the first enclosure 101a and the second enclosure 101b is larger at the bottom and smaller at the top, that is, the connecting portion between the first enclosure 101a and the second enclosure 101b is the bottom, conversely, the first enclosure 101a and the second enclosure 101b are not connected, that is, the opening side for passing trees is called the top.

[0037] Preferably, the first enclosure 101a and the extension rod 103a are arranged parallel to each other, that is, the first enclosure 101a is in a vertical state, and the second enclosure 101b includes a mounting plate 101b-1 that cooperates with the sealing plate 102a, and a second mounting plate 101b-2 that is fixedly connected to the mounting plate 101b and is arc-shaped.

[0038] In summary, after the tree passes through the sealing plate 102a and enters the space Z, the tree enters the arc-shaped second mounting plate 101b-2. When the working ring adopts the first enclosure 101a and the extension rod 103a to be arranged in parallel with each other, and the second enclosure 101b includes a mounting plate 101b-1 that cooperates with the sealing plate 102a, and a second mounting plate 101b-2 that is fixedly connected to the mounting plate 101b and presents an arc, the weight of the working ring can be reduced, and the difficulty of the user can be reduced. The arc-shaped second mounting plate 101b-2 increases the area of ​​the space Z. Furthermore, the tree near the top of the arc-shaped second mounting plate 101b-2 can be initially limited by the arc structure at the edge of the arc, that is, to prevent the tree from moving to the top of the space Z, and reduce the pressure of the blocking member 104 after the sealing plate 102a is closed.

[0039] The sealing member 102 comprises a sealing plate 102a, and a clamping column 102b and an installation column 102c are respectively provided at both ends of the sealing plate 102a. The clamping column 102b cooperates with the first enclosure 101a, and the installation column 102c cooperates with the second enclosure 101b.

[0040] Preferably, the sealing plate 102a is made of at least two or more hard materials, such as metal, insulating material, etc., and is connected by a clamping column 102b or an installation column 102c. At the same time, the installation column 102c is rotatably connected to the second enclosure 102b, so that the sealing plate 102a can rotate with the installation column 102c as the center.

[0041] Furthermore, if the gap between the sealing plates 102a is greater than or equal to the thickness of the covering member 101, the axis of the clamping column 102b connecting the sealing plates 102a is perpendicular to the plane of the covering member 101, and the clamping column 102b can be clamped into the clamping groove 101c.

[0042] The extension member 103 includes an operating rod 103 a connected to the covering member 101 and an extension rod 103 b slidably disposed on an outer wall of the operating rod 103 a .

[0043] Preferably, the extension rod 103b comprises a first extension sleeve 103e slidably connected to the outer wall of the operating rod 103a, a second extension sleeve 103d slidably connected to the outer wall of the first extension sleeve 103e, and a third extension sleeve 103c slidably connected to the second extension sleeve 103d;

[0044] An elastic positioning plate is disposed on the top of each extension sleeve, and the length of the overall extension member 103 is controlled by relative sliding between the sleeves.

[0045] Furthermore, the extension rod 103b includes at least one or more extension sleeves, and the length of the extension member 103a can be adjusted by adjusting the sliding between the extension sleeve and the operating rod 103a or the relative sliding between the extension sleeves, so that maintenance personnel are exempted from high-altitude operations.

[0046] Preferably, the present embodiment also provides the following scheme, the end of the extension member 103 away from the covering member 101 is movably connected to the second extension member 105, the second extension member 105 includes a first hinge 105c arranged at the end of the operating rod 103a away from the covering member 101 and a second hinge 105b rotatably connected to the first hinge 105c, and the end of the second hinge 105b away from the first hinge 105c is connected to the second operating rod 105a.

[0047] The maintenance personnel holds the second operating lever 105a and rotates the operating lever 103a to further adjust the angle of the tree pulling device.

[0048] Preferably, the first hinge 105c and the second hinge 105b are connected by an expansion bolt, and the angle between the second operating rod 105a and the operating rod 103a can be fixed by adjusting the expansion bolt, so that maintenance personnel can perform other operations conveniently.

[0049] The blocking member 104 includes a blocking bar 104a movably disposed on the first enclosure 101a and an elastic member 104c for limiting the movement of the blocking bar 104a;

[0050] The blocking bar 104a is movably matched with the clamping column 102b.

[0051] Preferably, the blocking bar 104a is rotatably disposed on the card slot 101c. In this embodiment, the blocking bar 104a is rotatably disposed in a receiving groove 101h opened in the first enclosure 101a and communicating with the card slot 101c;

[0052] Furthermore, the elastic member 104c is a compression spring, one end of which is fixedly connected to the blocking bar 104a, and the other end of which is fixedly connected to the inside of the receiving groove 101h;

[0053] Preferably, a second blocking bar 104b is provided on one side of the blocking bar 104a away from the sealing plate 102a. The second blocking bar 104b can be made of a hard material or an elastic material. When the clamping column 102b enters the clamping groove 101c, if the clamping column 102b has a tendency to escape from the clamping groove 101c, the second blocking bar 104b contacts the clamping column 102b first. When the second blocking bar 104b is made of an elastic material, a certain reverse force is provided for the escape of the clamping column 102b, so that the clamping column 102b continues to be stably located inside the clamping groove 101c, and the escape of the clamping column 102b is prevented, that is, the escape of trees or vines inside the space Z is prevented.

[0054] When the second blocking strip 104 b is made of a non-elastic material, the second blocking strip 104 b increases a certain strength for the blocking strip 104 a to prevent the clamping post 102 b from being separated from the inside of the clamping slot 101 c.

[0055] A clamping groove 101c is formed on the end surface of the first enclosure 101a, and a mounting groove 101d is formed on the end surface of the second enclosure 101b. The clamping column 102b is movably matched with the clamping groove 101c, and the mounting column 102c is movably matched with the mounting groove 101d.

[0056] A pull ring 102d is movably provided at one end of the sealing plate 102a, and an extension cord 102e is provided inside the pull ring 102d. Preferably, the extension cord 102e, the extension piece 103 and the second extension piece 105 are made of insulating material.

[0057] In summary, when in use, after placing a tree or vine in the space Z, pull the extension rope 102e to make the closing plate 102a close the space Z between the first enclosure 101a and the second enclosure 101b, and the maintenance personnel can adjust the falling direction of the tree by pulling the second operating rod 105a.

[0058] Example 3, reference Figures 1 to 11 , which is the third embodiment of the present invention, provides a tree pulling device, including embodiment 1, referring to Figure 1 to Figure 4 , which is the first embodiment of the present invention, provides a tree pulling device.

[0059] The clamping slot 101c includes a track slot 101f that fits the moving track of the clamping post 102b and a clamping slot 101g that limits the movement of the clamping post 102b.

[0060] It should be noted that in the present invention, the mounting post 102c of the sealing plate 102a is movably matched with the mounting groove 101d, that is, the mounting post 102c is rotatably connected to the mounting groove 101d, so the movement trajectory of the sealing plate 102a is an arc shape, and the trajectory groove 101f is an arc shape, which facilitates the clamping post 102b to enter the clamping groove 101g along the trajectory groove 101f.

[0061] The blocking bar 104a is rotatably disposed between the clamping groove 101g and the track groove 101f, and the length of the blocking bar 104a is greater than the width of the clamping groove 101g.

[0062] In summary, before the clamping post 102b enters the clamping slot 101g along the trajectory groove 101f, the clamping post 102b contacts the blocking bar 104a, so that the blocking bar 104a overcomes the elastic force of the elastic member 104c and enters the accommodating groove 101h. At this time, the extension rope 102e continues to be pulled to make the clamping post 102b enter the clamping slot 101g along the trajectory groove 101f, and the blocking bar 104a rebounds through the elastic force of the elastic member 104c, so that one end of the blocking bar 104a contacts the clamping slot 101c, preventing the clamping post 102b from escaping from the clamping slot 101g.

[0063] Preferably, a slide groove 104d is provided on the end surface of the blocking bar 104a away from the clamping groove 101g, and a slider 104f cooperating with the slide groove is provided in the slide groove 104d. The slider 104f and the slide groove 104d are connected by a second spring 104e. When the blocking bar 104a rebounds through the elastic force of the elastic member 104c, the slider 104f is made to contact the first enclosure 101a at the end away from the clamping groove 101g, thereby further enhancing the blocking strength of the blocking member 104.

[0064] Example 4 is the second example of the present invention. This example further provides a power distribution and maintenance system, including a tree traction device. By using the above-mentioned tree traction device in the power distribution and maintenance system, a total of 12,569 trees will be cleaned in the urban branch in 2022. According to the proportion of 30% of the partial tree cleaning, there are 3,770 trees that need to be pulled and cleaned in the urban branch alone. Each tree needs to be climbed and tied with a traction rope, which increases the risk of climbing and keeping a safe distance. It takes 10 minutes and 2 people to tie a traction rope for each tree climbed, and a total of 75,400 min*person is spent. The use of this tool avoids the risk of climbing and keeping a safe distance, and a set of tree traction only takes 3 minutes per person, and a total of 11,310 min*person is spent per year. From the above data, it can be clearly seen that the cumulative time saved is 64,090 min*person (1068.17 h*person).
