Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of power inspection tools, in particular to a branch cleaning device applied to a power transmission line. BACKGROUND

[0002] The branch cleaning device is a very common power transmission line inspection tool, which is used to clean the branches around the power transmission line to avoid the branches around the power transmission line from causing interference or safety accidents in growth. The existing branch cleaning devices mainly have two types. One is a saw type cleaning device, that is, a long rod is provided, and a tooth saw is arranged at the end of the long rod. The tooth saw is used to cut off the branches threatening the safe operation of the power transmission line to achieve branch cleaning. The other is a scissors type cleaning device, that is, a long rod is provided, and scissors are arranged at the end of the long rod. The scissors are used to cut off the branches threatening the safe operation of the power transmission line to achieve branch cleaning.

[0003] The existing branch cleaning device has the following disadvantages: 1) when the saw type cleaning device is used, the tooth saw needs to reciprocate on the branches. When sawing the branches, the branches cannot be fixed, so that the branches are easy to move synchronously with the tooth saw, and then the sawing operation of the branches is difficult. 2) when the scissors type cleaning device is used, the manual scissors can only cut off the branches with small sizes, and it is not easy to cut off the branches with large sizes. Although the electric scissors have large shearing force, the overall structure of the electric scissors is more complex, and the electric scissors carry a power supply, so that the overall weight is heavy, and it is more laborious to hold for a long time, which is not convenient to operate. 3) after the branches are sawed or cut off, there are many twigs on the branches, and the twigs are intertwined with each other, so that the sawed or cut branches cannot fall from the tree smoothly, and a tool with a hook needs to be used to pull them down, which results in low work efficiency.

DETAILED DESCRIPTION

[0035] In order to make the technical problems solved by the present application, the technical solutions adopted and the technical effects achieved more clear, the technical solutions of the embodiments of the present application will be further described in detail below with reference to the drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the present application.

[0036] As Figure 1As shown, the application provides a tree branch cleaning device (hereinafter referred to as a tree branch cleaning device) applied to a power transmission line, which is used for cleaning the tree branches 5 around the power transmission line to ensure the safe operation of the power transmission line. The tree branch cleaning device comprises a long rod 1, a chuck 2, a cutting assembly 3 and a guide assembly 4. Among them, the long rod 1 plays a supporting role, and the long rod 1 is provided in a telescopic structure or a detachable structure. By telescoping different lengths of the long rod 1 or splicing different numbers of long rods 1, the distance between the ground and the tree branches 5 to be cleaned can be adapted, so that the user can clean the tree branches 5 on the ground. The chuck 2 is arranged at the top end of the long rod 1, and the chuck 2 is provided in an openable and closable structure, so that the chuck 2 can clamp the tree branches 5. The cutting assembly 3 is a rope structure, and the cutting assembly 3 can be wound around the tree branches 5. The two ends of the cutting assembly 3 extend to the bottom end of the long rod 1, so that the user can pull the end of the cutting assembly 3 and make the cutting assembly 3 make reciprocating motion around the tree branches 5 to saw off the tree branches 5. The guide assembly 4 is installed on the long rod 1 and / or the chuck 2, and the guide assembly 4 is used to provide a guide function for the cutting assembly 3 to limit the movement path of the cutting assembly 3.

[0037] Specifically, referring to Figure 2 As shown, the chuck 2 comprises a base 21, a support 22 and two clamping jaws 23. The base 21 is installed at the top end of the long rod 1, and the support 22 and the two clamping jaws 23 are both installed on the base 21. The two clamping jaws 23 are arranged in a spaced manner on the side of the base 21 away from the long rod 1, and the clamping jaws 23 are rotatably connected with the base 21, so that the clamping jaws 23 can rotate relative to the base 21. By rotating the two clamping jaws 23, the ends of the two clamping jaws 23 away from the base 21 can be moved closer to or away from each other, that is, the opening and closing of the chuck 2 is realized. When the ends of the two clamping jaws 23 away from the base 21 are close to each other, the two clamping jaws 23 and the base 21 form an accommodating space 20 for accommodating the tree branches 5. It should be noted that since the tree branches 5 have a certain diameter, the accommodating space 20 can be closed, that is, the ends of the two clamping jaws 23 away from the base 21 abut each other; the accommodating space 20 can also be not closed, that is, the ends of the two clamping jaws 23 away from the base 21 are spaced a certain distance apart, and the distance between the two clamping jaws 23 is less than the diameter of the tree branches 5. The purpose of this structure is to use the two clamping jaws 23 to limit the tree branches 5 in the accommodating space 20, that is, to clamp the tree branches 5 by using the chuck 2. After the tree branches 5 are sawn off, the user pulls the chuck 2 downward by the long rod 1 to pull the sawn-off tree branches 5 to the ground, so as to avoid that the sawn-off tree branches 5 are left on the tree due to the entanglement of twigs.

[0038] The support 22 is located between the two clamps 23, one end of the support 22 extends into the accommodating space 20, and the support 22 is used to abut against the branch 5. In actual application, the user pushes the long rod 1 upward to make the support 22 abut against the bottom of the branch 5. The cutting assembly 3 successively saws the branch 5 downward from the top of the branch 5. During the sawing process, the top and bottom of the branch 5 can be forced, so that the branch 5 can be well fixed on the clamp 2, avoiding shaking during sawing, thereby improving the sawing efficiency.

[0039] The clamp 23 is in a "C" shape structure, so that when the two clamps 23 are close to each other, the accommodating space 20 can be formed therebetween. The clamp 23 includes at least two connecting rods, and adjacent two connecting rods are detachably connected through fasteners, so as to be spliced through different numbers of connecting rods, and the angle between adjacent two connecting rods is adjusted to adjust the size of the accommodating space 20, thereby adapting to different sizes of the branch 5. In the embodiment, the clamp 23 includes a mounting portion 234 and three connecting rods. The three connecting rods are a first connecting rod 231, a second connecting rod 232 and a third connecting rod 233 connected in sequence. Adjacent two connecting rods are fixedly connected through screws, so as to adjust the included angle between adjacent two connecting rods, thereby adjusting the size of the accommodating space 20. The first connecting rod 231 is rotationally arranged on the base 21. The mounting portion 234 is used to mount the cutting assembly 3, and the mounting portion 234 is arranged at one end of the third connecting rod 233 away from the second connecting rod 232. When the clamp 2 is opened and closed, the mounting portions 234 in the two clamps 23 are close to or away from each other. It should be noted that when the clamp 23 includes two connecting rods, the two connecting rods are located at two ends of the clamp 23, that is, one of the connecting rods is connected with the support 22, and the other connecting rod is used to mount the cutting assembly 3. When the clamp 23 includes three or more connecting rods, two connecting rods located at two ends in the length direction of the clamp 23, one of the connecting rods is connected with the support 22, and the other connecting rod is used to mount the cutting assembly 3.

[0040] Specifically, referring to Figures 3 to 5As shown, the support 22 is retractably arranged on the base 21. The chuck 2 further comprises a spring 24, a lock disc 25 and a limiting member 26. The base 21 is formed with a cavity 210, the lock disc 25 is arranged on the base 21, and one side of the lock disc 25 extends to the accommodating space 20, and the other side of the lock disc 25 extends to the cavity 210. The lock disc 25 is rotationally connected with the base 21, and a user can rotate the lock disc 25 relative to the base 21. The lock disc 25 is formed with a through hole 252 at the center for the support 22 to pass through. The support 22 comprises a support rod 221 and a support plate 222. The support rod 221 passes through the through hole 252, one end of the support rod 221 extends into the cavity 210, and the end of the support rod 221 is connected with the inner wall of the cavity 210 through the spring 24. The other end of the support rod 221 extends into the accommodating space 20, and the support plate 222 is arranged on the end of the support rod 221 located in the accommodating space 20. The support plate 222 is provided with a recess for the branch 5 to abut against. In actual application, the user pushes the base 21 upward through the long rod 1, and after the support plate 222 abuts against the branch 5, the entire support 22 moves downward relative to the base 21 and compresses the spring 24. When the support 22 is in a free state, the spring 24 can drive the support 22 to move upward relative to the base 21. That is, the retractable movement of the support 22 on the base 21 is realized.

[0041] The first connecting rod 231 comprises a first rod segment and a second rod segment arranged at an angle. The first connecting rod 231 is provided with two hinge points 2311 distributed at intervals, one of which is located at one end of the first rod segment away from the second rod segment, and the other is located at the connection between the first rod segment and the second rod segment. The end of the first rod segment away from the second rod segment is hinged to the support rod 221 through the hinge point 2311, and the hinge point 2311 at the end of the first rod segment away from the second rod segment is provided as a long hole to adapt to the rotation of the first connecting rod 231. The first rod segment and the support rod 221 are hinged through a pin shaft. The end of the second rod segment away from the first rod segment is connected with the second connecting rod 232, and the hinge point 2311 at the connection between the second rod segment and the first rod segment is hinged to the base 21. When the user operates the support 22 to abut against the branch 5, the support 22 moves downward relative to the base 21 and drives the claw 23 to rotate around the hinge point 2311 at the connection between the first rod segment and the second rod segment, so as to realize the rotation of the claw 23 driven by the retractable movement of the support 22. Figure 3 The arrow direction shown in the middle is the rotation direction of the claw 23.

[0042] One end of the first connecting rod 231 is located in the cavity 210 of the base 21, and the other end extends to the outside of the cavity 210 through the base 21. Correspondingly, the base 21 is formed with an avoiding hole 211 for the first connecting rod 231 to pass through.

[0043] The hole wall of the through hole 252 of the lock disc 25 is further provided with an unlocking slot 251, the slot opening of the unlocking slot 251 is communicated with the through hole 252, and the two ends of the unlocking slot 251 in the length direction (the X direction shown in the figure) are respectively communicated with the containing space 20 and the cavity 210. The support rod 221 is a hollow cylindrical structure, and two limiting pieces 26 are arranged on the side wall of the support rod 221. The limiting piece 26 is a triangular structure, one corner of the limiting piece 26 is rotationally connected with the inner wall of the support rod 221, and the two limiting pieces 26 are symmetrically arranged with respect to the axis of the support rod 221. The side wall of the support rod 221 is provided with an avoiding slot for the limiting piece 26 to pass through. The two limiting pieces 26 are elastically connected through a spring, and in the initial state, the spring drives the limiting piece 26 to rotate outward of the support rod 221, and one corner of the limiting piece 26 is located outside the support rod 221. When the limiting piece 26 is subjected to an external force, the limiting piece 26 can be rotated towards the inside of the support rod 221, and the entire limiting piece 26 is located inside the support rod 221, at which time the spring is compressed to store energy. In actual application, the chuck 2 has a locked state and an unlocked state. In the locked state, the lock disc 25 is rotated, so that the limiting piece 26 is staggered with the unlocking slot 251. When the support rod 221 moves towards the cavity 210 side, the limiting piece 26 passes through the through hole 252 from the containing space 20 into the cavity 210. When the limiting piece 26 passes through the through hole 252, the limiting piece 26 is extruded by the hole wall and rotates towards the inside of the support rod 221. When the limiting piece 26 moves into the cavity 210, the spring drives the limiting piece 26 to rotate towards the outside of the support rod 221. At this time, the limiting piece 26 is clamped on the side of the lock disc 25 towards the cavity 210. Under the limiting action of the limiting piece 26, the support 22 cannot move upwards relative to the base 21, thereby realizing the position locking of the clamping jaw 23. It can be understood that by locking the chuck 2, the two clamping jaws 23 are closed, the branch 5 is limited in the containing space 20, and the user can pull down the long rod 1 to take the branch 5 off the tree. In the unlocked state, the lock disc 25 is rotated, so that the limiting piece 26 is opposite to the unlocking slot 251. The spring 24 drives the support rod 221 to move upwards relative to the base 21, and the limiting piece 26 passes through the unlocking slot 251 from the cavity 210 into the containing space 20.

[0044] In particular, with reference to Figure 8As shown, the cutting assembly 3 includes multiple rope segments connected in sequence, a first connector 34, a second connector 35, and two handles 33. There are three rope segments, two of which are pull ropes 32, which can be made of existing materials such as nylon rope, plastic rope, or hemp rope. The other rope segment is a wire saw 31, which is a prior art device consisting of multiple metal rings with blades connected in series to form a chain. The wire saw 31 reciprocates across the surface of the branch 5 to cut it. The wire saw 31 is located between the two pull ropes 32, with both ends connected to the two pull ropes 32 respectively. The two handles 33 are respectively located at the ends of the two pull ropes 32 opposite to the wire saw 31. The wire saw 31 and the pull ropes 32 form a complete chain structure, allowing the cutting assembly 3 to bend freely. The cutting assembly 3 is folded in half from the middle and mounted on the clamp 2. Two pull ropes 32 have handles 33 at one end extending toward the end of the long rod 1 away from the base 21, so that the user can hold them on the handles 33. When sawing a tree, the position of the wire saw 31 is adjusted appropriately so that the wire saw 31 is wrapped around the branch 5. The branch 5 is sawed off by pulling the cutting assembly 3 back and forth around the branch 5.

[0045] To allow the cutting assembly 3 to wrap around the branch 5, it needs to be divided into two parts. In this embodiment, the wire saw 31 is disconnected from one of the pull ropes 32, and a first connector 34 is installed at the end of the disconnected wire saw 31, while a second connector 35 is installed at the end of the disconnected pull rope 32. The first connector 34 and the second connector 35 are detachably connected to allow for the disconnection and connection of the entire cutting assembly 3.

[0046] Specifically, refer to Figure 6 and Figure 7 As shown, the first connector 34 includes a first connecting post with a cylindrical structure and a locking ring 341 disposed on the first connecting post. The locking ring 341 has a circular ring structure. The second connector 35 includes a second connecting post with a cylindrical structure and a latch 351 disposed on the second connecting post. The latch 351 has a circular ring structure. The latch 351 includes a circular ring and a spring piece 3511. The circular ring has a notch, and the spring piece 3511 is mounted on the circular ring and can seal the notch. Under the elastic force of the spring piece 3511, the spring piece 3511 abuts against the inner ring side of the circular ring. When the first connector 34 is connected to the second connector 35, the locking ring 341 passes through the notch of the latch 351, and the locking ring 341 pushes the spring piece 3511 inward. After the spring piece 3511 disengages from the locking ring 341, it rebounds and seals the notch, so that the locking ring 341 is restricted inside the latch 351.

[0047] Before sawing the tree, the first connecting head 34 and the second connecting head 35 are respectively detachably installed on the two installation portions 234. The two clamping jaws 23 are brought close to each other at the ends with the installation portions 234 to realize the connection of the first connecting head 34 and the second connecting head 35. Specifically, the installation portions 234 are provided with installation grooves 2341, i.e. the installation grooves 2341 are located at the ends of the clamping jaws 23 away from the base 21. The installation grooves 2341 are in communication with the bottom surfaces of the installation portions 234 and the side surfaces facing each other of the two installation portions 234. The first connecting column of the first connecting head 34 is inserted into one of the installation grooves 2341, and the second connecting column of the second connecting head 35 is inserted into the other installation groove 2341. The plane where the locking ring 341 is located is perpendicular to the plane where the locking buckle 351 is located, so that when the two installation portions 234 are brought close to each other, the locking ring 341 penetrates into the locking buckle 351. At the same time, in order to make the first connecting head 34 and the second connecting head 35 be connected stably on the installation portions 234, the groove walls of the installation grooves 2341 are provided with magnets 2342, which are used to magnetically attract and connect the first connecting head 34 and the second connecting head 35. In use, the first connecting head 34 and the second connecting head 35 are first installed on the two installation portions 234, and the two installation portions 234 are away from each other. After the branches 5 enter the containing space 20 from the gap between the two installation portions 234, the two clamping jaws 23 are closed. At this time, the first connecting head 34 and the second connecting head 35 are connected together. The user pulls down the cutting assembly 3 to make the first connecting head 34 and the second connecting head 35 be separated from the corresponding installation portions 234, and finally the cutting assembly 3 is overlapped on the top of the branches 5.

[0048] It should be noted that in actual application, the first connecting head 34 can be arranged at one end of the rope saw 31, and the second connecting head 35 can be correspondingly arranged at one end of the pulling rope 32. Alternatively, the second connecting head 35 can be arranged at one end of the rope saw 31, and the first connecting head 34 can be correspondingly arranged at one end of the pulling rope 32. By installing the first connecting head 34 or the second connecting head 35 at one end of the rope saw 31, it is beneficial to make the rope saw 31 closer to the installation portions 234. When the two connecting heads are connected, the user pulls the connecting heads to be separated from the clamping jaws 23. At this time, it is not necessary to greatly adjust the position of the rope saw 31, and the rope saw 31 can be directly overlapped on the branches 5.

[0049] In another embodiment, referring to Figure 9As shown, the cutting assembly 3 includes three pull ropes 32, a rope saw 31 and two handles 33. The two handles 33 are respectively arranged on the two pull ropes 32 located at the two ends of the cutting assembly 3. The three pull ropes 32 are respectively a first pull rope, a second pull rope and a third pull rope. In the direction shown from left to right, the first pull rope, the rope saw 31, the second pull rope, the third pull rope are sequentially connected. The two handles 33 are respectively arranged on the first pull rope and the third pull rope. The second pull rope and the third pull rope are disconnected, the first connecting head 34 is arranged at one end of the second pull rope away from the rope saw 31, and the second connecting head 35 is arranged at one end of the third pull rope away from the handle 33. The structure makes the connecting head and the rope saw 31 spaced apart by one pull rope 32, so that the connecting head is away from the rope saw, avoiding affecting the normal work of the rope saw 31 due to the contact between the connecting head and the branch 5. In actual application, the specific number and size of the pull rope 32 are matched and arranged according to the overall structure size of the branch cleaning device.

[0050] Specifically, referring to Figure 1 As shown, the guide assembly 4 includes a plurality of guide cylinders 41 and a plurality of guide wheels 42. The guide cylinder 41 is made of ceramic material to have good wear resistance and small friction coefficient. The cutting assembly 3 is arranged in the guide cylinder 41 and slides along the length direction of the guide cylinder 41. The guide wheel 42 also plays a guiding role, and the cutting assembly 3 is arranged around the periphery of the guide wheel 42. The guide wheel 42 can be used in two groups to make the cutting assembly 3 clamped between the two guide wheels 42. The guide cylinder 41 and the guide wheel 42 are installed on the long rod 1 and / or the base 21. Of course, in actual application, the number and position of the guide cylinder 41 and the guide wheel 42 can be reasonably arranged according to the specific extension path of the cutting assembly 3.

[0051] In this embodiment, the method for using the branch cleaning device is as follows:

[0052] Step S10, the clamp head 2 is in an open state, and the first connecting head 34 and the second connecting head 35 are respectively inserted into the mounting slot 2341 of the two mounting portions 234.

[0053] Step S20, the long rod 1 is lifted, and the clamp head 2 is close to the branch 5 to be cleaned.
