Description

Technical Field

[0001] The present invention relates to the technical field of electric power construction, and in particular to a tree tying device and a tree branch processing method. Background Art

[0002] During outdoor construction and maintenance work on high-altitude transmission racks and the lines on the transmission racks, it is usually necessary to remove obstacles that endanger the safe operation of the lines. In outdoor environments, the obstacles are usually extremely high tree branches, which are usually at a height that operators standing on the ground cannot grab with their hands. In order to remove extremely high branches and control the direction of the branches' fall to ensure the safety of the removal operation, in the related art, it is usually necessary to use a tree tying device to tie the branches, and then pull down the tree tying device to bend the branches in a predetermined direction. Specifically, the tree tying device includes a connected support rod, a tree tying mechanism and a control mechanism. The operator needs to transport the tree tying mechanism to the vicinity of the target branch through the support rod, and manipulate the control mechanism to make the tree tying mechanism hold the branch to be tied, and finally pull down the support rod to bend the branch in a predetermined direction.

[0003] However, on the one hand, during the tree tying process, the operator needs to simultaneously complete the two actions of lifting the support rod and operating the control mechanism. On the other hand, since the support rod needs to be able to support the tree tying mechanism, the support rod is a hard rod structure. As a result, after the tree is tied, when the operator pulls down the support rod, the support rod is likely to interfere with the ground, making it difficult for the operator to use the existing tree tying device to tie and pull the tree. Summary of the Invention

[0048] To make the technical problems solved, the technical solutions adopted, and the technical effects achieved by the present invention more clearly understood, the technical solutions of the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It is apparent that the described embodiments are only some of the embodiments of the present invention, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort shall fall within the scope of protection of the present invention.

For example, they may refer to fixed connections, detachable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention in specific circumstances.

[0050] In the present invention, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Furthermore, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0051] like Figure 1 and Figure 2 As shown, a first aspect of the present invention provides a tree tying device 1, comprising a device body 10, a support rod 11, a movable structure 12, a first flexible belt 13, a first locking structure 14, and a second flexible belt 15. The device body 10 is a U-shaped structure that half surrounds the outer periphery of a storage space 100. The device body 10 has two end portions 101 spaced apart from each other. The storage space 100 has an opening 102 located between the two end portions 101. A first plug-in structure 161 is provided on a side of the device body 10 facing away from the opening 102. A second plug-in structure 162 is provided at one end of the support rod 11. The second plug-in structure 162 is plugged into the first plug-in structure 161 along the relative direction between the first plug-in structure 161 and the opening 102. At least one end 101 is hingedly connected to a movable structure 12, which can rotate relative to the device body 10 to expose the opening 102. 02 or block at least part of the opening 102, the first flexible belt 13 is connected between the movable structure 12 and the end portion 101 opposite to the movable structure 12, the side of the first flexible belt 13 facing the opening 102 can abut against the branch 2 to be tied, and drive the movable structure 12 to rotate relative to the device body 10 to block at least part of the opening 102, the first locking structure 14 is provided at the end portion 101, the first locking structure 14 can lock the movable structure 12 in a state of blocking at least part of the opening 102, one end of the second flexible belt 15 is connected to the device body 10, and the other end of the second flexible belt 15 naturally droops for the operator to grasp.

[0052] By arranging so that the side of the first flexible belt 13 facing the opening 102 can abut against the branch 2 to be tied, and driving the movable structure 12 to rotate relative to the device body 10 to cover at least part of the opening 102, the operator can lift the support rod 11 toward the branch 2 to allow the branch 2 to pass through the opening 102 and enter the accommodating space 100. At the same time, the first flexible belt 13 can abut against the branch 2, and drive the movable structure 12 and the first flexible belt 13 to cooperate to hold the branch 2, so that the operator does not need to perform other operations except lifting the support rod 11 to achieve tree tying.

[0053] Furthermore, by making the support rod 11 and the device body 10 plug-in connected through the first plug-in structure 161 and the second plug-in structure 162, and making the first plug-in structure 161 and the second plug-in structure 162 pluggable along the relative direction between the first plug-in structure 161 and the opening 102, after completing the tree tying, the operator can pull down the support rod 11, so that the device body 10 and the support rod 11 connected to the branch 2 are respectively subjected to opposite forces along the relative direction between the first plug-in structure 161 and the opening 102, thereby being able to The first plug-in structure 161 is separated from the second plug-in structure 162, so that the support rod 11 can be removed. During the tree pulling work, the operator does not need to face the problem of the hard support rod 11 interfering with the ground. Instead, the operator can pull down the device body 10 by grasping and pulling down the second flexible belt 15, so that the device body 10 drives the tied branch 2 to bend in a predetermined direction. Since the second flexible belt 15 is flexible, the second flexible belt 15 will not interfere with the ground, and the operator's tree pulling work is less difficult.

[0054] It is understood that the first locking structure 14 can have a variety of different structures, as long as the first locking structure 14 can maintain the movable structure 12 in a state of at least partially covering the opening 102 after the tree branch 2 abuts the first flexible band 13, driving the movable structure 12 to rotate relative to the device body 10 to a state of at least partially covering the opening 102. The following describes two specific structures of the first locking structure 14 as examples.

[0055] Optionally, the first locking structure 14 includes a one-way bearing, and the movable structure 12 is hinged to the end 101 via the one-way bearing, so that the first locking structure 14 enables the movable structure 12 to rotate from a state of exposing the opening 102 to a state of blocking at least part of the opening 102 along a predetermined rotation direction of the one-way bearing under the drive of the first flexible belt 13, but cannot rotate from a state of blocking at least part of the opening 102 to a state of exposing the opening 102 along a direction opposite to the predetermined rotation direction. Moreover, since the tree branch 2 is located in the accommodating space 100 when the first locking structure 14 rotates under the drive of the first flexible belt 13, it can prevent the movable structure 12 from continuing to rotate along the predetermined rotation direction, thereby enabling the movable structure 12 to maintain a state of blocking at least part of the opening 102.

[0056] It is understandable that after the tree felling work is completed, the movable structure 12 and the device body 10 can be removed from the branch 2 as a whole to vacate the accommodation space 100, and then the movable structure 12 can be rotated along the predetermined rotation direction to pass through the accommodation space 100 to return to the state of exposing the opening 102 again.

[0057] Please combine Figure 3 and Figure 4 As shown, another option is that the first locking structure 14 includes an elastic member 140 and a first locking member 141. The elastic member 140 is connected between the first locking member 141 and the device body 10. The elastic member 140 can apply an elastic force to the first locking member 141, so that the first locking member 141 has a tendency to approach the movable structure 12 along the thickness direction of the movable structure 12. The movable structure 12 has a first surface 120. When the movable structure 12 blocks at least a portion of the opening 102, the first surface 120 faces away from the opening 102, and the first locking member 141 can abut against the first surface 120, thereby preventing the movable structure 12 from rotating toward the first locking member 141 to return to a state exposing the opening 102. Since the branch 2 is located in the accommodating space 100, it can block the movable structure 12 from rotating back to a state exposing the opening 102 from a side of the movable structure 12 away from the first locking member 141, thereby maintaining the movable structure 12 in a state of blocking at least a portion of the opening 102.

[0058] Optionally, one first locking structure 14 may be provided corresponding to one movable structure 12 , or two first locking structures 14 may be provided, and the two first locking structures 14 are respectively located at two opposite sides of the movable structure 12 along its own thickness direction.

[0059] In order to avoid the situation in which the movable structure 12 rotates relative to the device body 10 to block at least part of the opening 102 during the operator's lifting of the support rod 11, making it difficult for the movable structure 12 to work in conjunction with the first flexible belt 13 to achieve the function of holding the branch 2, optionally, the movable structure 12 is provided with a temporary locking hole 121 that passes through along its own thickness direction, and the first locking member 141 can extend into the temporary locking hole 121, so that the movable structure 12 is in a state of exposing the opening 102, and the outer periphery of the first locking member 141 has relative guide surfaces 1410 and locking surfaces 1411, and the guide surfaces 1410 are at least partially inclined relative to the thickness direction of the movable structure 12, and the guide surfaces 1410 can abut against the hole wall of the temporary locking hole 121 close to the first surface 120 to guide the first locking member 141 away from the movable structure 12 along the thickness direction of the movable structure 12, and the locking surface 1411 and the first surface 120 are both parallel to the thickness of the movable structure 12 The locking surface 1411 can abut against the first surface 120, so that before the operator lifts the support rod 11, the first locking piece 141 can be extended into the temporary locking hole 121, so that the movable structure 12 can maintain the state of exposing the opening 102 under the action of a small external force. When the operator lifts the support rod 11 until the tree branch 2 abuts against the first flexible belt 13, the operator can lift the support rod 11 toward the tree branch 2 with greater force, so that the first flexible belt 13 is subjected to a larger reaction force, driving the first locking piece 141 to abut against the guide surface 1410, so that the force applied to the guide surface 1410 can resist the elastic force applied by the elastic piece 140, so that the first locking piece 141 moves away from the movable structure 12 along the thickness direction of the movable structure 12 until the first locking piece 141 is disengaged from the temporary locking hole 121, thereby allowing the movable structure 12 to rotate relative to the device body 10 to cover at least a portion of the opening 102. Furthermore, when the movable structure 12 blocks at least part of the opening 102, the locking surface 1411 can abut against the first surface 120. Since the locking surface 1411 and the first surface 120 are both parallel to the thickness direction of the movable structure 12, the interaction force between the locking surface 1411 and the first surface 120 is perpendicular to the thickness direction of the movable structure 12. In other words, the first locking member 141 will not be subjected to a force in the opposite direction of the elastic force applied by the elastic member 140. Thus, the first locking member 141 can stably lock the movable structure 12 in a state of blocking at least part of the opening 102.

[0060] Optionally, the device body 10 is provided with a sliding hole 103 that passes through the device body 10 along its own thickness direction, and the first locking piece 141 includes a locking portion 1412, which is slidably connected to the sliding hole 103 along the thickness direction of the device body 10, and the locking portion 1412 can abut against the first surface 120, and the elastic piece 140 is connected between the locking portion 1412 and the device body 10, and is slidably connected with the locking portion 1412 through the sliding hole 103, which can limit the movement trajectory of the locking portion 1412 approaching and moving away from the movable structure 12, so that the locking process of the locking portion 1412 is better controlled, and the locking and unlocking effects of the locking portion 1412 are more stable.

[0061] Furthermore, the first locking member 141 also includes an unlocking portion 1413, which is connected to the locking portion 1412. The unlocking portion 1413 extends from the sliding hole 103 to the outside of the device body 10, so that the unlocking portion 1413 can be grasped and pulled out away from the movable structure 12, thereby driving the locking portion 1412 to disengage from the movable structure 12 to achieve unlocking of the movable structure 12, so that the operator can restore the movable structure 12 to a state exposing the opening 102 after completing the tree felling work.

[0062] Preferably, the movable structure 12 can be provided with a temporary locking hole 121 that passes through along its own thickness direction, and the outer periphery of the first locking piece 141 has relative guide surfaces 1410 and locking surfaces 1411. At the same time, the device body 10 is provided with a sliding hole 103 that passes through along its own thickness direction, so that the tree-holding function of the movable structure 12 is more stable.

[0063] At this time, it can be understood that the outer periphery of the locking portion 1412 has a guide surface 1410 and a locking surface 1411 .

[0064] like Figure 2 As shown, optionally, one of the first plug-in structure 161 and the second plug-in structure 162 includes a plug, and the other includes a slot, so that the first plug-in structure 161 and the second plug-in structure 162 are plugged in by the plug and the slot cooperating and plugging in along the relative direction of the opening 102 and the first plug-in structure 161.

[0065] Optionally, at least part of the outer circumference of the plug is a conical surface, so that the radial dimension of the end of the plug close to the bottom of the slot is smaller than the radial dimension of the end of the plug away from the bottom of the slot, thereby enabling the plug to be guided into the slot through the conical surface of the outer circumference of the plug, making it easier for the operator to connect the first plug structure 161 with the second plug structure 162.

[0066] Optionally, at least one of the outer periphery of the plug and the groove wall of the slot is provided with an elastic pad 163, so that when the first plug-in structure 161 and the second plug-in structure 162 are plugged in, the elastic pad 163 can be pressed between the first plug-in structure 161 and the second plug-in structure 162, so that the plug-in stability of the first plug-in structure 161 and the second plug-in structure 162 is better, and the first plug-in structure 161 and the second plug-in structure 162 are avoided from separating during the operator lifting the support rod 11, and the device body 10, the movable structure 12, the first flexible belt 13 and the second flexible belt 15 are accidentally dropped as a whole.

[0067] Preferably, at least part of the outer circumference of the plug can be a conical surface, and at least one of the outer circumference of the plug and the groove wall of the slot can be provided with an elastic pad 163, so that the first plug-in structure 161 and the second plug-in structure 162 can be more convenient to use and more stable.

[0068] like Figure 2 、 Figures 5 to 8 As shown, optionally, the first plug-in structure 161 includes a slot, and a connecting hole 1610 connected to the slot is opened on the outer periphery of the first plug-in structure 161, and the second plug-in structure 162 includes a plug, and a limiting hole 1620 that can be correspondingly connected to the connecting hole 1610 is opened on the outer periphery of the second plug-in structure 162. The tree tying device 1 also includes a second locking structure 17, and the second locking structure 17 includes a second locking member 170 and a transmission mechanism 171. The second locking member 170 has a first end 1701 and a second end 1702 opposite to each other. The first end 1701 is located on the outer periphery of the first plug-in structure 161, and the second end 1702 can be inserted into the connecting hole 1610 and the limiting hole 1620. The transmission mechanism 171 Connected between the second locking piece 170 and the first locking piece 141, when the movable structure 12 exposes the opening 102, the first locking piece 141 abuts against one side of the movable structure 12 along its own thickness direction, and the first locking piece 141 uses the transmission mechanism 171 to make the second locking piece 170 in a state where the second end 1702 is inserted into the connecting hole 1610 and the limiting hole 1620. When the movable structure 12 blocks at least part of the opening 102, the first locking piece 141 approaches the movable structure 12 along the thickness direction of the movable structure 12, and the first locking piece 141 uses the transmission mechanism 171 to make the second locking piece 170 in a state where the second end 1702 is inserted into the connecting hole 1610 and detached from the limiting hole 1620.

[0069] Thus, the first locking member 141 and the second locking member 170 can be linked together by the transmission mechanism 171, and then Figure 5 and Figure 6As shown, when the movable structure 12 is in a state of exposing the opening 102, the first locking member 141 is maintained in a state of abutting against one side of the movable structure 12 along its own thickness direction, and correspondingly, the second locking member 170 is maintained in a state of inserting the second end 1702 into the limiting hole 1620 to lock the first plug structure 161 and the second plug structure 162. Therefore, when the movable structure 12 does not hold the branch 2, it is difficult to separate the first plug structure 161 from the second plug structure 162. Figure 7 and Figure 8 As shown, when the movable structure 12 is in a state of blocking at least a portion of the opening 102, the first locking member 141 is maintained in contact with the first surface 120 of the movable structure 12. At the same time, the second locking member 170 is maintained at the second end 1702 disengaged from the limiting hole 1620 to unlock the first plug-in structure 161 and the second plug-in structure 162. Therefore, when the movable structure 12 embraces the tree branch 2, the first plug-in structure 161 and the second plug-in structure 162 can be easily separated. This arrangement enables the operator to have good connection stability between the first plug-in structure 161 and the second plug-in structure 162 when lifting the support rod 11 so that the opening 102 of the device body 10 corresponds to the branch 2 to be tied, and it is not easy for the device body 10, the movable structure 12, the first flexible belt 13 and the second flexible belt 15 to fall off as a whole accidentally. At the same time, after the movable structure 12 successfully hugs the branch 2, the first plug-in structure 161 and the second plug-in structure 162 are easily separated, so that the tree tying device 1 is safer and more convenient to use.

[0070] Optionally, the transmission mechanism 171 includes a transmission rod 1710 and a hinge structure 1711, and the two opposite ends of the transmission rod 1710 are respectively hinged to the first locking member 141 and the first end 1701, and the middle part of the transmission rod 1710 is hinged to the device body 10 through the hinge structure 1711, so that the two opposite ends of the transmission rod 1710 can respectively drive the first locking member 141 and the second locking member 170 to move in two approximately opposite directions through the transmission rod 1710 and the hinge structure 1711.

[0071] At this time, the moving trajectory of the first locking member 141 and the second locking member 170 can be an arc trajectory centered on the hinge structure 1711. Optionally, there is a certain redundant space between the hole wall of the sliding hole 103 and the outer periphery of the first locking member 141 to avoid interference between the first locking member 141 and the hole wall of the sliding hole 103, and there is a certain redundant space between the hole wall of the connecting hole 1610 and the outer periphery of the second locking member 170 to avoid interference between the second locking member 170 and the hole wall of the connecting hole 1610.

[0072] Optionally, the tree tying device 1 includes two movable structures 12, which are hinged at two end portions 101 respectively, and the two opposite ends of the first flexible belt 13 are respectively connected to the two movable structures 12, so that any one movable structure 12 is connected to the spaced end portions 101 in turn through the first flexible belt 13, so that the two movable structures 12 can be used to jointly block the opening 102. Compared with using only one movable structure 12 to block the opening 102, the length of a single movable structure 12 can be shortened, thereby reducing the movable space required for the movable structure 12, and reducing the possibility of other obstacles existing in the movable space of the movable structure 12 when using the tree tying device 1 for tree tying operations, which makes it difficult for the movable structure 12 to hold the tree branch 2 to be tied.

[0073] Optionally, the movable structure 12 has a second surface 122. When the movable structure 12 blocks at least part of the opening 102, the second surface 122 faces the opening 102. The second surface 122 is protruded with a sharp tooth structure 123. The sharp tooth structure 123 is used to abut against the branch 2 and partially insert into the surface of the branch 2 when the movable structure 12 embraces the branch 2, so that the relative position of the movable structure 12 and the branch 2 is more stable.

[0074] Optionally, the device body 10 includes a connected support frame 104 and a device shell 105, the support frame 104 is at least partially arranged in the device shell 105, the first plug-in structure 161 is arranged on the support frame 104, the support frame 104 has an end 101, and the interior of the device shell 105 is connected to the accommodating space 100, so that the support frame 104 can provide more stable support for the movable structure 12 and the first flexible belt 13, and the connection stability of the support frame 104 and the support rod 11 through the first plug-in structure 161 and the second plug-in structure 162 is better, and the device shell 105 can shield the support frame 104 and the connection structure between the support frame 104 and other components, which can play a certain protective role.

[0075] When, as described in the aforementioned technical solution, the device body 10 is provided with a sliding hole 103 that passes through the device body 10 along its own thickness direction, the support frame 104 and the device housing 105 may be respectively provided with multiple sliding holes 103, and along the thickness direction of the device body 10, the sliding holes 103 set on the support frame 104 and the device housing 105 are correspondingly connected.

[0076] The second aspect of the present invention provides a method for tying a rope. Figure 1 and Figure 2 As shown, the tree tying device 1 as described in the first aspect is used to tie up a high branch 2. The tying method includes:

[0077] S1 . The movable structure 12 is placed in a state where the opening 102 is exposed.

[0078] When, as described in the above technical solution, the movable structure 12 is provided with a temporary locking hole 121 penetrating along the thickness direction of the movable structure 12, step S1 may include:

[0079] S10 , the movable structure 12 is in a state of exposing the opening 102 , and the first locking member 141 is extended into the temporary locking hole 121 .

[0080] S2. The operator lifts the support rod 11 upward, so that the branch 2 to be tied enters the accommodating space 100 through the opening 102 and abuts against the first flexible belt 13, so that the first flexible belt 13 drives the movable structure 12 to rotate relative to the device body 10 until it covers at least part of the opening 102.

[0081] Therefore, the operator only needs to lift the support rod 11 upwards to complete the tree tying operation.

[0082] S3 , the operator pulls the support rod 11 downward to separate the second plug-in structure 162 from the first plug-in structure 161 .

[0083] Therefore, the operator only needs to pull the support rod 11 downward to remove the support rod 11 from the device body 10, so that the operator does not need to face the problem of interference between the hard support rod 11 and the ground during the subsequent tree pulling work.

[0084] S4. The operator grasps the lower end of the second flexible belt 15 and pulls down the second flexible belt 15 to drive the device body 10, the movable structure 12 and the first flexible belt 13 downward as a whole, so that the branch 2 bends in a predetermined direction.

[0085] Since the second flexible belt 15 is flexible, the second flexible belt 15 will not interfere with the ground, and the operator's tree pulling operation is less difficult.
