Description

Technical Field

[0001] This invention belongs to the field of power supply maintenance technology, and specifically relates to a transmission rope controller. Background Technology

[0002] Currently, when carrying out high-altitude operations such as power transmission line maintenance and live-line work, a transfer rope is usually used to pass tools and materials. During this process, because the tower has a certain inclination, in order to avoid collisions between the tools and materials and the tower, one worker needs to control the tail rope. This creates a reaction force between the person pulling the rope and the person controlling the tail rope, making it more strenuous for the person pulling the rope.

[0003] In addition, even when workers are controlling the tail rope, collisions between tools and materials and the tower body often occur. Currently, the tools used are mostly electric hydraulic tools, precision instruments, moisture-proof live-line working tools, and other valuable tools. Once a collision occurs, the tools are likely to fall, which will not only damage the tools but also threaten the personal safety of the workers. Summary of the Invention

[0004] This invention provides a transmission rope controller, which aims to solve the technical problems of existing transmission ropes being laborious to use and tools being prone to falling.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is: to provide a transmission rope controller, including a pulley block and a braided rope wound on the pulley block, wherein the pulley block includes:

[0006] A fixing frame is used to fix it to the tower body. The fixing frame is equipped with a driving mechanism, and the driving mechanism has a rotating part.

[0007] A first connecting shaft is rotatably connected to the fixed frame via a first rotating shaft, the axis of the first rotating shaft being perpendicular to the axis of the first connecting shaft and coaxially connected to the rotating part; and

[0008] Two pulleys are rotatably connected to opposite ends of the first connecting shaft, and the axial direction of the pulleys is parallel to the axial direction of the first shaft.

[0009] The transmission rope controller also includes a pull rope assembly disposed on the traction section of the braided rope, the pull rope assembly having a limiting hole through which the tail section of the braided rope passes.

[0010] In one possible implementation, the drive mechanism is a motor, the output shaft of which forms the rotating part, and the rope assembly is provided with a control button that is communicatively connected to the motor.

[0011] In one possible implementation, the drive mechanism includes:

[0012] A torsion spring, one end of which is fixed to the fixing frame and the other end is sleeved on the first rotating shaft, the torsion spring forming the rotating part, and the torsion spring having a preload force to keep the first connecting shaft in a horizontal state;

[0013] A connecting rope, one end of which is fixed to the outer circumferential surface of the first rotating shaft; and

[0014] A traction ring is fixed to the other end of the connecting rope and sleeved on the traction section of the braided rope. The traction ring is used to pull the first rotating shaft to rotate.

[0015] In one possible implementation, the pull cord assembly includes:

[0016] First frame;

[0017] A first reel, rotatably connected to the first frame, forms a gap between the first reel and the top of the first frame for the traction section of the braided rope to pass through; and

[0018] The second reel is rotatably connected to the first frame, and the axial direction of the second reel is parallel to the axial direction of the first reel. The second reel and the first reel are spaced apart to form the limiting hole.

[0019] In some embodiments, the outer peripheral surface of the first spool is provided with a barb, and the outer peripheral surface of the second spool is provided with a groove corresponding to the barb.

[0020] In one possible implementation, the transfer rope controller further includes a toolbox detachably connected to the end of the braided rope, the toolbox having a storage space for holding tools.

[0021] The toolbox described in some embodiments includes:

[0022] Box;

[0023] A sleeve is fitted around the outer periphery of the housing and slides along the axial direction of the sleeve with the housing.

[0024] A drawstring bag is located at the top of the sleeve, with one end fixed to the drawstring bag and the other end fixed to the bottom of the box body.

[0025] An elastic element is disposed between the housing and the sleeve, the elastic element having a pre-tightening force that brings the housing closer to the pocket.

[0026] In some embodiments, the toolbox is provided with cushioning foam, which encloses and forms multiple spaced-apart storage slots, and the multiple storage slots constitute the storage space.

[0027] In some embodiments, the toolbox is provided with rollers at the bottom, the axis of which is parallel to the axis of the first rotating shaft.

[0028] In some embodiments, the outer periphery of the roller is provided with a plurality of fixing rods, and the plurality of fixing rods are evenly distributed around the axial direction of the roller.

[0029] In this embodiment, the first connecting shaft is initially horizontal, and the two pulleys are distributed left and right (see...). Figure 1 At this point, the braided rope is passed through the limiting hole, and then through the top of the two pulleys in sequence. The upper section forms the traction section, and the lower section forms the tail section. The traction section is fixed to the rope assembly. The required tool is installed on the tail section, and then the traction section of the braided rope is pulled. The traction section pulls the tail section, and the tail section drives the tool to rise. During the pulling process, the rotation of the first shaft can be adjusted through the drive mechanism. For example, when the tool rises to a distance close to the tower body, the first shaft can be rotated. The first shaft drives the two pulley shafts to rotate, and the two pulleys become vertically distributed (see...). Figure 4 At this point, the braided rope only rolls in conjunction with the upper pulley, reducing the distance between the traction section and the tail section. This allows the tool to move away from the tower until it is pulled to a high altitude. Compared to existing technologies, the present invention's transmission rope controller adjusts the state of the two pulleys through a drive mechanism, thereby adjusting the distance between the traction section and the tail section. With a smaller distance, the tool can move away from the tower, thus avoiding collisions and preventing the tool from falling and causing safety accidents. Both the traction section and the tail section are threaded onto the rope assembly, allowing one operator to operate both sections simultaneously, saving manpower and simplifying operation.

[0043] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0044] Please refer to the following: Figures 1 to 7 The present invention will now describe the transmission rope controller. The transmission rope controller includes a pulley group 13 10 and a braided rope 20 sleeved on the pulley group 13 10. The pulley group 13 10 includes a fixed frame 11, a first connecting shaft 12, and two pulleys 13. The fixed frame 11 is fixed to the tower body and has a drive mechanism 40, which has a rotating part. The first connecting shaft 12 is rotatably connected to the fixed frame 11 via a first rotating shaft 14. The axial direction of the first rotating shaft 14 is perpendicular to the axial direction of the first connecting shaft 12 and coaxially connected to the rotating part. The two pulleys 13 are rotatably connected to opposite ends of the first connecting shaft 12, and the axial direction of the pulleys 13 is parallel to the axial direction of the first rotating shaft 14. The transmission rope controller also includes a rope pulling assembly 30 disposed on the traction section 21 of the braided rope 20. The rope pulling assembly 30 has a limiting hole through which the tail section 22 of the braided rope 20 passes.

[0045] It should be noted that when the first connecting shaft 12 is horizontal, the two pulleys 13 are distributed left and right, which is state one; when the first connecting shaft 12 is vertical, the two pulleys 13 are distributed up and down, which is state two.

[0046] In the actual use of the transmission rope controller provided in this embodiment, the first connecting shaft 12 is initially inclined to a horizontal state, and the two pulleys 13 are distributed left and right (see...). Figure 1 At this point, the braided rope 20 is passed through the limiting hole, and then through the top of the two pulleys 13 in sequence. The upper section forms the traction section 21, and the lower section forms the tail section 22. The traction section 21 is fixed on the rope assembly 30. The required tool is installed on the tail section 22, and then the traction section 21 of the braided rope 20 is pulled. The traction section 21 pulls the tail section 22, and the tail section 22 drives the tool to rise. During the pulling process, the rotation of the first rotating shaft 14 can be adjusted by the drive mechanism 40. For example, when the tool rises to a distance close to the tower body, the first rotating shaft 14 can be rotated. The first rotating shaft 14 drives the two pulleys 13 to rotate, and the two pulleys 13 become vertically distributed (see...). Figure 4 At this time, the braided rope 20 only rolls and cooperates with the pulley 13 above, and the gap between the traction section 21 and the tail section 22 becomes smaller, which allows the tool to move away from the tower until it is pulled to a high altitude.

[0047] Compared with the prior art, the present invention's transmission rope controller adjusts the state of the two pulleys 13 through the drive mechanism 40, thereby adjusting the distance between the traction section 21 and the tail section 22. When the distance is smaller, the tool can be moved away from the tower body, thereby avoiding collision with the tower body and preventing the tool from falling and causing safety accidents. The traction section 21 and the tail section 22 are both threaded on the pull rope assembly 30, and one operator can operate the traction section 21 and the tail section 22 at the same time, saving manpower and facilitating operation.

[0048] In some embodiments, a specific implementation of the drive mechanism 40 described above may employ, as follows: Figures 1 to 2 The structure shown. See also Figures 1 to 2 The drive mechanism 40 is a motor 41, and the output shaft of the motor 41 forms a rotating part. The rope assembly 30 is equipped with a control button 42 that is communicatively connected to the motor 41. When operating, the operator can press the control button 42 on the rope assembly 30 to control the output shaft of the motor 41 to rotate or stop, thereby realizing the rotation control of the first rotating shaft 14. This is convenient to operate, adaptable to the actual site conditions, and reduces labor intensity.

[0049] In some embodiments, a modified implementation of the drive mechanism 40 described above may employ, as follows: Figures 4 to 5 The structure shown. See also Figures 4 to 5The drive mechanism 40 includes a torsion spring 43, a connecting rope 44, and a traction ring 45. One end of the torsion spring 43 is fixed to the fixed frame 11, and the other end is sleeved on the first rotating shaft 14. The torsion spring 43 forms a rotating part and has a preload force to keep the first connecting shaft 12 in a horizontal state. One end of the connecting rope 44 is fixed to the outer circumferential surface of the first rotating shaft 14. The traction ring 45 is fixed to the other end of the connecting rope 44 and sleeved on the traction section 21 of the braided rope 20. The traction ring 45 is used to pull the first rotating shaft 14 to rotate.

[0050] When the traction section 21 is pulled, the friction between the traction section 21 and the traction ring 45 causes the traction ring 45 to move in the direction of movement of the traction section 21. Since the traction ring 45 is connected to the outer circumference of the first rotating shaft 14 through the connecting rope 44, when the traction ring 45 moves downward, it pulls the connecting rope 44 and thus pulls the first rotating shaft 14 to overcome the elastic force of the torsion spring 43 and rotate it by a certain angle, so that the two pulleys 13 are distributed vertically, which can shorten the distance between the traction section 21 and the tail section 22, and pull the traction section 21 to drive the tail section 22 away from the tower body; after the tool is transferred, the traction section 21 is stopped, the torsion spring 43 returns to its initial state and pulls the traction ring 45, so that the first rotating shaft 14 remains in a horizontal state.

[0051] In this embodiment, construction personnel can make real-time adjustments according to the site conditions during operation, which is convenient and effectively prevents the tools on the tail section 22 from colliding with the tower body.

[0052] In some embodiments, a specific implementation of the above-described pull cord assembly 30 may employ, as follows: Figures 1 to 5 The structure shown. See also Figures 1 to 5 The rope assembly 30 includes a first frame 31, a first reel 32, and a second reel 33. The first reel 32 is rotatably connected to the first frame 31, and a gap is formed between the top of the first reel 32 and the first frame 31 for the traction section 21 of the braided rope 20 to pass through. The second reel 33 is rotatably connected to the first frame 31, and the axis of the second reel 33 is parallel to the axis of the first reel 32. The second reel 33 and the first reel 32 are spaced apart to form a limiting hole. When the braided rope 20 is pulled, the traction section 21 is pulled down, and the tail section 22 rises. The downward movement of the traction section 21 drives the first reel 32 to rotate. The first reel 32 and the second reel 33 rotate in opposite directions. The friction between the first reel 32 and the tail section 22, and the friction between the second reel 33 and the tail section 22, both help the tail section 22 to move upward, avoiding any reaction force between the traction section 21 and the tail section 22, making the operation more time-saving and labor-saving.

[0053] In some embodiments, an improved implementation of the above-described pull cord assembly 30 may employ, as follows: Figure 2 , Figure 3 and Figure 5 The structure shown. See also Figure 2 , Figure 3 and Figure 5 The outer circumference of the first spool 32 is provided with spikes 321, and the outer circumference of the second spool 33 is provided with grooves 331 corresponding to the spikes 321. When the traction section 21 is pulled, the spikes 321 on the first spool 32 are inserted into the traction section 21, and the traction section 21 can be directly driven downward by rotating the first spool 32; similarly, the first spool 32 and the second spool 33 are rotated in opposite directions, and the spikes 321 are inserted into the tail section 22, driving the tail section 22 upward. This not only assists in moving the tool upward, but the spikes 321 also play a fixing role, preventing the braided rope 20 from slipping off.

[0054] Specifically, in order to facilitate the rotation of the first spool 32, a hand crank or drive motor 41 coaxial with the first spool 32 can be installed on the first frame 31.

[0055] In some embodiments, an improved implementation of the above-described transfer rope controller may employ, as follows: Figures 1 to 7 The structure shown. See also Figures 1 to 7 The pass rope controller also includes a toolbox 50 detachably connected to the tail section 22 of the braided rope 20, with the toolbox 50 containing a storage space for holding tools. By setting the toolbox 50 at the tail section 22, when tools need to be passed, they can simply be placed inside the toolbox 50 for high-altitude passing, preventing tools from falling.

[0056] In some embodiments, a specific implementation of the toolbox 50 described above may adopt the following approach: Figure 6 The structure shown. See also Figure 6 The toolbox 50 includes a box body 51, a sleeve 52, a drawstring bag 53, and an elastic element 54. The sleeve 52 is fitted around the outer periphery of the box body 51 and slides along the axial direction of the sleeve 52 with the box body 51. The drawstring bag 53 is located on the top of the sleeve 52 and has a drawstring 55. One end of the drawstring 55 is fixed to the drawstring bag 53, and the other end is fixed to the bottom of the box body 51. The elastic element 54 is located between the box body 51 and the sleeve 52 and has a pre-tightening force that brings the box body 51 closer to the drawstring bag 53.

[0057] When tools need to be placed inside, pull the drawstring 55 of the storage bag 53 to widen the opening. At this time, the drawstring 55 on the storage bag 53 pulls the box body 51 closer to the storage bag 53. After the tools are placed inside, due to the weight of the tools, the box body 51 can be pushed down, moving it away from the storage bag 53. As the box body 51 descends, pull the storage bag 53.

[0058] This embodiment automatically closes the bag 53 by utilizing the weight of the tool, thus maintaining the closed state of the bag 53 when the tool is inside the box 51 during tool transfer, preventing the tool from falling and improving safety performance.

[0059] In some embodiments, an improved implementation of the toolbox 50 described above may employ, as follows: Figure 7 The structure shown. See also Figure 7 The toolbox 50 is equipped with cushioning foam 56, which forms multiple spaced-apart storage slots, creating a storage space. Since the tools being transported are mostly high-precision tools such as electric hydraulic tools, precision instruments, and moisture-proof live-line working tools, the cushioning foam 56 prevents the tools from being damaged by friction inside the toolbox 50, ensuring the precision of the tools.

[0060] It should be noted that cushioning foam 56 not only provides cushioning, but also has strong plasticity, low cost, and is easy to adapt to the placement of different tools.

[0061] In some embodiments, an improved implementation of the toolbox 50 described above may employ, as follows: Figure 7 The structure shown. See also Figure 7 The bottom of the toolbox 50 cover is equipped with rollers 57, and the axis of the rollers 57 is parallel to the axis of the first rotating shaft 14. When passing tools, if the toolbox 50 collides with the tower body, as the toolbox 50 moves upward, the rollers 57 roll on the tower body, which can stabilize the movement of the toolbox 50 after contact with the tower body, thereby avoiding violent shaking of the toolbox 50 and effectively reducing the risk of the tool falling.

[0062] In some embodiments, an improved implementation of the roller 57 described above may employ, as follows: Figure 7 The structure shown. See also Figure 7 The roller 57 has multiple protruding fixing rods 58 on its outer periphery, which are evenly distributed around the axial direction of the roller 57. Since the tower body is generally a mesh conical frame when working at heights, when the toolbox 50 contacts the tower body, the fixing rods 58 on the roller 57 can be inserted into the tower body in this embodiment. As the roller 57 rotates, the fixing rods 58 cooperate with the mesh on the tower body to assist the upward movement of the toolbox 50 and share the weight of the toolbox 50. When the operator pulls the traction section 21, the weight of the toolbox 50 is reduced, making the operation more time-saving and labor-saving.

[0063] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
