Description

Technical Field

[0001] This invention discloses a winding device for tail rope, belonging to the technical field of tail rope winding devices. Background Technology

[0002] During power construction, winches are frequently used. To facilitate the winding of the winch's tail rope, a tail rope winding device is required. In use, a motor drives the winding rollers to rotate and wind the tail rope. Many power construction sites (such as those erecting high-voltage lines using tower cranes) are typically located at the top, on slopes, or on hillsides. The tail rope winding device usually weighs 180-150 kg and needs to be transported to the mountainside by engineering vehicles. However, general motor vehicle roads usually only lead to the foot of the mountain, hundreds or even thousands of meters away from the construction site. The roads between the foot of the mountain and the construction site are often narrow, making them impassable for engineering vehicles. In such cases, the tail rope winding device must be manually transported to the construction site. Due to its weight, transporting the tail rope winding device is extremely difficult. Furthermore, the winding rollers are located on the top of the base, requiring the base to be lifted during manual transport. This results in a high center of gravity for the entire tail rope winding device. On rugged, sloping mountain roads, manually transporting equipment with a high center of gravity can easily cause it to tip over, posing a significant safety hazard. Summary of the Invention

[0003] The purpose of this invention is to solve the problems of inconvenient handling and easy tipping of traditional tail rope winding devices. To this end, a winch tail rope winding device is provided, which can lower the center of gravity of the tail rope winding device during handling, making the handling of the tail rope winding device easier and less labor-intensive.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A winding device for winding a tail rope includes a frame, a winding roller rotatably connected to the frame, and a drive assembly for driving the winding roller to rotate. The frame is provided with a guide rod for lifting and lowering the winding roller, and the winding roller is provided with a connecting seat slidably connected to the guide rod. The bottom of the frame is provided with a clearance notch. The winding roller has an operating position positioned at the top of the guide rod and a transport position positioned at the bottom of the guide rod. When the winding roller is in the transport position, part of the winding roller passes through the clearance notch so that the bottom end face of the winding roller is lower than the bottom end face of the frame, and the rotation of the winding roller is used to assist the movement of the frame.

[0006] The beneficial effects of using the present invention are:

[0007] The frame described in this invention has a guide rod, along which the winding roller can be raised and lowered. The winding roller has an operating position and a transport position. When the winding roller is in the operating position, it is positioned at the top of the guide rod. The drive assembly drives the winding roller to rotate, thereby winding the tail rope. When the winding roller needs to be transported, it moves to the bottom of the guide rod, moving it to the transport position. After the winding roller descends, the overall center of gravity of the tail rope winding device is lowered, making it easier for transporters to carry the rope on rough or sloping terrain and reducing the possibility of the tail rope winding device tipping over. This design improves safety during transport. Furthermore, as the winding roller moves to the transport position, it passes through an avoidance gap during its descent, with its lowest point below the bottom surface of the frame, allowing it to directly contact the ground. When road conditions are suitable for the winding roller to travel, it can rotate on the road surface, thus assisting the movement of the tail rope winding device. This makes transporting the tail rope winding device easier and less labor-intensive, increasing its transport speed, reducing manpower, and improving safety during transport.

[0008] Preferably, the drive assembly includes a motor base, a drive motor, and a clutch mechanism. The end of the winding roller is provided with a drive shaft that is connected to the output shaft of the drive motor. The axial direction of the drive shaft is perpendicular to the axial direction of the output shaft of the drive motor. The clutch mechanism controls the drive motor to move closer to or away from the drive shaft. By adopting the aforementioned technical solution, the axial length of the tail rope winding device on the winding roller can be reduced, which facilitates the tail rope winding device's passage through narrower paths and makes it easier to transport. It also reduces the possibility of the drive assembly being subjected to collisions. Furthermore, the clutch mechanism can control the engagement or disengagement of the drive motor and the drive shaft. When the winding roller is winding the tail rope, the clutch mechanism engages the drive shaft with the drive motor, enabling electric winding, making tail rope winding more effortless and convenient. When the rotation of the winding roller is used to assist in the movement of the frame, the clutch mechanism disengages the drive shaft from the drive motor, effectively preventing damage to the drive motor due to the rotation of the winding roller.

[0009] Preferably, the clutch mechanism includes an adjusting member, and the drive motor is provided with a sliding frame that is slidably connected to the motor base. The adjusting member is connected to the sliding frame in a transmission manner and drives the sliding frame to move closer to or away from the drive shaft.

[0010] Preferably, the motor mount is equipped with a limiting block, and when the drive motor is connected to the transmission shaft, the sliding frame abuts against the limiting block. Using the aforementioned technical solution, the limiting block can restrict the movement range of the drive motor, preventing the drive motor from getting too close to the transmission shaft and thus obstructing the transmission between the drive motor and the transmission shaft; in addition, the limiting block allows the user to clearly perceive that the drive motor has completed the transmission connection with the transmission shaft, serving as a prompt and improving the user experience.

[0011] Preferably, the winding roller includes a winding frame and two wheel frames slidably connected to the winding frame. The diameter of the wheel frames is larger than the diameter of the winding frame. A drive shaft is fixedly connected to the end of the winding frame. A drive screw, which is axially connected to the wheel frames, passes through the winding frame. The drive screw rotates relative to the winding frame, causing the two wheel frames to move towards or away from each other. Using the aforementioned technical solution, the winding frame is used to wind up the tail rope. The diameter of the wheel frames is larger than the diameter of the winding frame. When the winding roller is in the transport position, the wheel frames contact the ground and act as rollers to assist the tail rope winding device in movement. The wheel frames prevent direct contact between the winding frame and the ground, reducing the possibility of damage to the winding frame. Furthermore, the drive screw can adjust the distance between the two wheel frames. When the road surface is narrow, the drive screw controls the two wheel frames to move closer together, making the distance between the two wheel frames smaller than the width of the road surface. This allows the wheel frames to move on the road surface, enabling the tail rope winding device to move in narrow areas, which is beneficial for transporting the tail rope winding device.

[0012] Preferably, the end of the transmission screw away from the drive assembly is provided with a handwheel, the handwheel is provided with a connecting sleeve, the connecting sleeve extends to the outer periphery of the transmission shaft, the connecting sleeve is provided with a first locking member for locking the transmission shaft, the first locking member locks the transmission shaft so that the transmission screw rotates synchronously with the transmission shaft, and the first locking member releases the transmission shaft so that the transmission screw rotates relative to the transmission shaft.

[0013] Preferably, the connecting seat is provided with a sliding hole for the guide rod to pass through and a first threaded hole communicating with the sliding hole. A second locking member is installed in the first threaded hole. The second locking member passes through the first threaded hole and abuts against the guide rod, thereby restricting the sliding of the connecting seat and the guide rod. Using the aforementioned technical solution, the second locking member can fix the connecting seat in a designated position, which helps improve the positioning stability of the winding roller, reduces the possibility of the connecting seat falling arbitrarily, and improves the safety of the tail rope winding device.

[0014] Preferably, the top of the connecting seat is provided with a second threaded hole, and the top of the guide rod is provided with a third locking member. The third locking member cooperates with the second threaded hole to position the winding roller in the operating position. By adopting the aforementioned technical solution, the third locking member and the second locking member cooperate to position the connecting seat in the operating position, which can further improve the positioning stability of the winding roller, reduce the possibility of the connecting seat falling arbitrarily, and improve the safety of the tail rope winding device.

[0015] Preferably, the connecting seat is provided with a shaft hole through which the drive shaft passes, a bearing is installed in the shaft hole, and an oil injection hole communicating with the shaft hole is provided at the bottom of the second threaded hole, and the oil injection hole is provided with a sealing plug.

[0016] Preferably, the frame includes two U-shaped rods and two parallel square tubes. The guide rods are fixed to the top of the square tubes. The two ends of the U-shaped rods are inserted into the ends of the two square tubes and form a sliding connection with the square tubes. The surface of the square tubes is provided with elongated slots. The surface of the U-shaped rods is provided with studs that pass through the elongated slots. The studs are provided with fasteners. The fasteners cooperate with the studs to restrict the relative sliding between the U-shaped rods and the square tubes.

However, the following embodiments are only preferred embodiments of the present invention and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of the present invention.

Therefore, they should not be construed as limitations on this invention.

[0036] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise expressly defined.

[0037] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0038] like Figures 1 to 14 As shown in the figure, this embodiment demonstrates a winding device for winding a tail rope, including a frame 2, a winding roller 1 rotatably connected to the frame 2, and a drive assembly 5 for driving the winding roller 1 to rotate. The frame 2 is provided with a guide rod 201 for lifting and lowering the winding roller 1. The winding roller 1 is provided with a connecting seat 3 slidably connected to the guide rod 201. The bottom of the frame 2 is provided with a clearance notch. The winding roller 1 has an operating position positioned at the top of the guide rod 201 and a transport position positioned at the bottom of the guide rod 201. When the winding roller 1 is in the transport position, the winding roller 1 partially passes through the clearance notch so that the bottom surface of the winding roller 1 is lower than the bottom surface of the frame 2, and the rotation of the winding roller 1 is used to assist the movement of the frame 2.

[0039] In this embodiment, the frame 2 has a guide rod 201, and the winding roller 1 can be raised and lowered along the guide rod 201. The winding roller 1 has an operating position and a transport position. When the winding roller 1 is in the operating position, it is positioned at the top of the guide rod 201. The drive assembly 5 drives the winding roller 1 to rotate, thereby winding the tail rope. When the winding roller 1 needs to be transported, it moves to the bottom of the guide rod 201, moving it to the transport position. After the winding roller 1 descends, it can lower the overall center of gravity of the tail rope winding device, making it easier for transporters to carry the rope on rugged or inclined terrain, and reducing the difficulty of tail rope winding. The device is less prone to tipping over, thus improving safety during transport. Furthermore, as the winding roller 1 moves to the transport position, it passes through an obstacle clearance during its descent, with its lowest point below the bottom surface of the frame 2, allowing it to directly contact the ground. When road conditions are suitable for the winding roller 1 to travel, it can rotate on the road surface, thus assisting the movement of the tail rope winding device. This makes transporting the tail rope winding device easier and less strenuous, increasing its transport speed, reducing manpower, and improving safety during transport.

[0040] like Figure 3 and Figure 10 As shown, in this embodiment, the winding roller 1 includes a winding frame 10 and two wheel frames 11 slidably connected to the winding frame 10. The winding frame 10 includes two connecting plates 102 and a plurality of sliding rods 101. The plurality of sliding rods 101 are evenly distributed circumferentially. The two connecting plates 102 are respectively fixed to the two ends of the sliding rods 101. All the sliding rods 101 are fixed by the two connecting plates 102. The connecting plates 102 and the sliding rods 101 are assembled to form the winding frame 10. In this embodiment, when the tail rope is wound, the tail rope is wound along the outer periphery of the winding frame 10. The wheel frame 11 is provided with a sliding sleeve 111 slidably connected to the sliding rods 101. Through the cooperation of the sliding sleeve 111 and the sliding rods 101, the wheel frame 11 can slide along the axial direction of the winding frame 10, and the diameter of the wheel frame 11 is larger than the diameter of the winding frame 10.

[0041] like Figures 5 to 7As shown, the drive assembly 5 in this embodiment includes a motor base 52, a drive motor 51, and a clutch mechanism 53. The end of the winding roller 1 is provided with a drive shaft 4 that is connected to the output shaft of the drive motor 51. The drive shaft 4 is fixedly connected to the connecting plate 102. The axial direction of the output shaft of the drive motor 51 is perpendicular to the axial direction of the drive shaft 4. The output shaft of the drive motor 51 is connected with a first helical tooth 514. A coupling 54 is provided at one end of the drive shaft 4 near the drive motor 51. The connecting shaft 541 of the coupling 54 is provided with a second helical tooth 515. The drive shaft 4 and the drive motor 51 are connected by the meshing of the first helical tooth 514 and the second helical tooth 515. In this embodiment, the axial direction of the output shaft of the drive motor 51 is perpendicular to the axial direction of the drive shaft 4, which can reduce the length of the tail rope winding device in the axial direction of the winding roller 1, which is beneficial for the tail rope winding device to pass through narrower roads, making it easier to transport the tail rope winding device, and also reducing the possibility of the drive assembly 5 being hit.

[0042] like Figure 6 and Figure 7As shown, in this embodiment, the drive motor 51 is provided with a sliding frame 511 slidably connected to the motor base 52. The clutch mechanism 53 includes an adjusting member 531 and a guide rail 522 for the sliding frame 511 to slide. The bottom of the motor base 52 is provided with a through hole 521 for the sliding frame 511 to pass through. The guide rail 522 is fixedly installed on the bottom of the motor base 52, and the length direction of the guide rail 522 is parallel to the axial direction of the drive shaft 4. The sliding frame 511 is provided with a slider 512 slidably connected to the guide rail 522. 2. Fixed between the two side walls of the sliding frame 511, during installation, the side walls of the sliding frame 511 pass through the through hole 521 and slide with the guide rail 522 through the slider 512. The slider 512 slides along the guide rail 522, thereby driving the sliding frame 511 to slide along the through hole 521. One end of the adjusting member 531 passes through the motor base 52 and is threadedly connected to the connecting hole 513 of the sliding frame 511. The other end protrudes from the outside of the motor base 52 and can be rotated. The motor base 52 is provided with a passage for the adjusting member 531 to pass through. A mounting hole is provided, and a bearing is installed inside the mounting hole. The adjusting member 531 passes through the bearing and is rotatably connected to the motor base 52 through the bearing. At the same time, the bearing restricts the axial movement of the adjusting member 531. A positioning spring 533 is sleeved on the adjusting member 531. The positioning spring 533 is located between the sliding frame 511 and the motor base 52 and is always kept in a compressed state. When the drive motor 51 and the drive shaft 4 are in a transmission connection, the positioning spring 533 acts on the sliding frame 511 to keep the drive motor 51 and the drive shaft 4 in a stable connection. When the drive shaft 4 and the drive motor 51 need to be separated, the adjusting member 531 is rotated to drive the sliding frame 511 away from the drive shaft 4 along the guide rail 522 until the first helical tooth 514 and the second helical tooth 515 separate from each other. At this time, the positioning spring 533 is kept in a compressed state. When the drive shaft 4 and the drive motor 51 need to be engaged, the adjusting member 531 is rotated in the opposite direction to drive the sliding frame 511 closer to the drive shaft 4 along the guide rail 522 until the first helical tooth 514 and the second helical tooth 515 mesh with each other. At this time, the drive motor 51 and the drive shaft 4 maintain transmission.

[0043] To prevent the drive motor 51 from moving excessively, the motor base 52 in this embodiment is provided with a limiting block 534. When the drive motor 51 is connected to the transmission shaft 4, the sliding bracket 511 abuts against the limiting block 534. The limiting block 534 can restrict the movement range of the drive motor 51, preventing the drive motor 51 from getting too close to the transmission shaft 4 and causing the transmission between the drive motor 51 and the transmission shaft 4 to be obstructed. In addition, the limiting block 534 can make the user clearly aware that the drive motor 51 has completed the transmission connection with the transmission shaft 4, which can serve as a prompt and improve the user experience.

[0044] like Figure 4 , Figure 8 and Figure 9As shown, in this embodiment, the winding frame 10 is provided with a transmission screw 6 that is connected to the wheel frame 11 in the axial direction. The surface of the transmission screw 6 inside the winding frame 10 is provided with two sections of threads with opposite directions of rotation. Both wheel frames 11 are connected to the transmission screw 6. The transmission screw 6 rotates relative to the winding frame 10, causing the two wheel frames 11 to move towards or away from each other. The distance between the two wheel frames 11 can be adjusted by the transmission screw 6. When the road surface is relatively narrow, the two wheel frames 11 are controlled to move closer to each other by the transmission screw 6, so that the distance between the two wheel frames 11 is less than the width of the road surface, so as to allow the wheel frames 11 to move on the road surface. This allows the tail rope winding device to be pushed and pulled on narrow roads, which is beneficial for the transportation of the tail rope winding device.

[0045] like Figure 4 As shown, in this embodiment, the drive shaft 4 has a through hole 40 for the drive screw 6 to pass through. A handwheel 8 is provided at the end of the drive screw 6 away from the drive assembly 5. The handwheel 8 has a connecting sleeve 9. A positioning hole 80 is provided on the side of the handwheel 8 facing the connecting sleeve 9. A connecting post 90 is provided on the side of the connecting sleeve 9 facing the handwheel 8. The positioning hole 80 and the connecting post 90 are inserted into each other to achieve a fixed connection between the handwheel 8 and the connecting sleeve 9. The connecting sleeve 9 extends to the outer periphery of the drive shaft 4 and has a first lock for locking the drive shaft 4. The first locking member 91 locks the transmission shaft 4 so that the transmission screw 6 rotates synchronously with the transmission shaft 4. The first locking member 91 releases the transmission shaft 4 so that the transmission screw 6 rotates relative to the transmission shaft 4. When it is necessary to adjust the distance between the two wheel frames 11, the first locking member 91 releases its engagement with the transmission shaft 4 so that the transmission screw 6 can rotate relative to the transmission shaft 4. Then, the transmission screw 6 is rotated by the handwheel 8. The two wheel frames 11 move towards or away from each other under the action of the transmission screw 6.

[0046] like Figure 11 As shown, in this embodiment, the connecting seat 3 is provided with a sliding hole 31 for the guide rod 201 to pass through and a first threaded hole 32 communicating with the sliding hole 31. Two parallel guide rods 201 are vertically arranged on both sides of the frame 2. The connecting seat 3 is slidably connected to the guide rods 201 through two sliding holes 31 corresponding to the two guide rods 201. The middle part of the connecting seat 3 is located between the two guide rods 201. The middle part of the connecting seat 3 is provided with a shaft hole 30 for the drive shaft 4 to pass through. The connecting seat 3 is internally installed with a bearing 35, and the connecting seat 3 is rotatably connected to the transmission shaft 4 through the bearing 35. In addition, in this embodiment, a second locking member 321 is installed in the first threaded hole 32. The second locking member 321 passes through the first threaded hole 32 and abuts against the guide rod 201, thereby restricting the sliding between the connecting seat 3 and the guide rod 201. The second locking member 321 can fix the connecting seat 3 in a designated position, which is beneficial to improving the positioning stability of the winding roller 1, reducing the possibility of the connecting seat 3 falling arbitrarily, and improving the safety of the tail rope winding device.

[0047] In this embodiment, the top of the connecting seat 3 is provided with a second threaded hole 33, and the top of the guide rod 201 is provided with a third locking member 331. The third locking member 331 cooperates with the second threaded hole 33 to position the winding roller 1 in the operating position. The third locking member 331 and the second locking member 321 cooperate with each other to position the connecting seat 3 in the operating position, which can further improve the positioning stability of the winding roller 1, reduce the possibility of the connecting seat 3 falling arbitrarily, and improve the safety of the tail rope winding device. In addition, the bottom of the second threaded hole 33 is provided with an oil injection hole 34 communicating with the shaft hole 30. The oil injection hole 34 is provided with a sealing plug 341. When the tail rope winding device is used for a long time, the user can inject lubricating oil into the oil injection hole 34. The lubricating oil flows into the shaft hole 30 through the oil injection hole 34, thereby lubricating the bearing 35 and the drive shaft 4, which is beneficial to improving the service life of the bearing 35 and the drive shaft 4.

[0048] like Figure 11 As shown, in this embodiment, the frame 2 includes two U-shaped rods 21 and two parallel square tubes 20. A guide rod 201 is fixed to the top of the square tube 20, and a support block 204 is provided at the bottom of the square tube 20. The two ends of the U-shaped rods 21 are respectively inserted into the ends of the two square tubes 20 and form a sliding connection with them. The surface of the square tube 20 is provided with an elongated slot 202, and the surface of the U-shaped rods 21 is provided with studs 211 passing through the elongated slots 202. The studs 211 are provided with fasteners 212, which cooperate with the studs 211 to restrict the movement of the U-shaped rods 21. The relative sliding of the square tube 20, through the cooperation of the fastener 212 and the stud 211, can control the movement of the U-shaped rod 21 in the length direction of the square tube 20, thereby adjusting the length of the frame 2 in the length direction of the square tube 20, so that the tail rope winding device can pass through relatively narrow road surfaces; in addition, in order to strengthen the strength of the guide rod 201, a reinforcing rod 203 is provided between the top end of the guide rod 201 and the square tube 20 in the embodiment. The reinforcing rod 203 can increase the stability of the guide rod 201 and reduce the possibility of the guide rod 201 breaking.

[0049] like Figure 1 and Figure 2 As shown, at this time, the winding roller 1 is in the operating position for winding the tail rope, that is, the connecting seat 3 moves to the top of the guide rod 201 and is positioned by the second locking member 321 and the third locking member 331. At the same time, the frame 2 is placed on the ground by the support block 204, and the first locking member 91 abuts against the transmission shaft 4, thereby making the transmission shaft 4 and the transmission screw 6 rotate synchronously. Meanwhile, the drive motor 51 maintains a transmission connection with the transmission shaft 4 under the action of the clutch mechanism 53. Then, the drive motor 51 is started. The drive motor 51 drives the transmission shaft 4 to rotate through the cooperation of the first helical tooth 514 and the second helical tooth 515. The transmission shaft 4 drives the winding roller 1 to rotate through the connecting plate 102, thereby winding the tail rope.

[0050] like Figure 12 As shown, when the tail rope winding device needs to be moved, the second locking member 321 and the third locking member 331 are released, allowing the connecting seat 3 to move freely along the guide rod 201. This allows the connecting seat 3 to descend to the bottom of the guide rod 201 and reach the moving position. To prevent the winding roller 1 from sliding arbitrarily, the connecting seat 3 is positioned by the second locking member 321 after the winding roller 1 is in the moving position. If the road surface is not suitable for pushing, two people can lift and move the device by holding the U-shaped rod 21 from the front and back. Of course, other tools such as ropes can also be used to lift and move the device by shoulder. As the winding roller 1 descends to the top, the center of gravity of the tail rope winding device is lowered and closer to the ground, making the tail rope winding device more stable and less prone to tipping over during the moving process.

[0051] like Figure 14 As shown, when the road surface is suitable for pushing, the clutch mechanism 53 controls the drive motor 51 to move away from the transmission shaft 4, so that the transmission shaft 4 and the drive motor 51 are separated. At this time, the winding roller 1 is in the transport position, and the lowest end of the wheel frame 11 is lower than the bottom surface of the support block 204. The wheel frame 11, as the roller of the tail rope winding device, contacts the road surface. The user pushes the tail rope winding device to make the wheel frame 11 roll on the road surface, thereby assisting the tail rope winding device to move on the wheel surface.

[0052] like Figure 13 As shown, when the road surface is suitable for the wheel frame 11 to push, and when the road width is less than the distance between the two wheel frames 11, the first locking member 91 releases the drive shaft 4, allowing the drive screw 6 and the drive shaft 4 to rotate relative to each other. The user rotates the handwheel 8 to drive the drive screw 6 to rotate relative to the drive shaft 4. Under the action of the drive screw 6, the two wheel frames 11 move closer to each other, thereby reducing the distance between the two wheel frames 11 until the distance between the two wheel frames 11 is less than the road width to allow the wheel frame 11 to be pushed on the road. After adjustment, the first locking member 91 is used again to abut against the drive shaft 4, so that the drive shaft 4 and the drive screw 6 rotate synchronously, so that the wheel frame 11 can be pushed by the auxiliary tail rope winding device.

[0053] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Those skilled in the art should understand that the present invention includes, but is not limited to, the contents described in the accompanying drawings and the specific embodiments above. Any modifications that do not depart from the functional and structural principles of the present invention will be included within the scope of the claims.
