Description

Technical Field

[0001] This invention relates to the field of cable traction, and in particular to an adjustable winch and its method of use. Background Technology

[0002] In power line construction, cable laying, and maintenance, small winches are widely used for pulling cables, optical cables, and guide ropes due to their portability and flexibility. Existing small winches typically use drums with a fixed diameter or fixed taper. In practical use, to adapt to different construction tasks, it is often necessary to change to pull cables of different diameters.

[0003] Currently, the equipment faces the following limitations when dealing with cables of various specifications: First, the fixed structure of the drum cannot change its working surface shape, resulting in excessively loose rope arrangement and easy rope entanglement when pulling thin ropes, while insufficient space leads to tight rope arrangement and mutual compression when pulling thick ropes. This incompatibility not only exacerbates cable wear but also easily causes rope tangling and jamming during multi-layer winding, posing safety hazards and seriously affecting traction efficiency. Second, to solve the problem of multi-cable diameter compatibility, existing technologies require the use of multiple drums of different specifications for replacement, which is cumbersome and time-consuming. Summary of the Invention

[0004] This invention provides an adjustable winch that can solve the problem of poor adaptability of existing small winches when facing the need to repeatedly pull cables of various specifications.

[0005] An adjustable winch and its method of use, comprising:

[0006] The support mechanism includes a mounting base, on which a drive motor is mounted, and a pivot rod connected to the drive motor is horizontally rotatably mounted on the mounting base.

[0007] A winding mechanism is installed on the pivot rod. The winding mechanism has multiple rotatable support members. The multiple support members are divided into two groups and symmetrically distributed on the pivot rod. Both groups of support members are arranged in a circular array around the axis of the pivot rod to form a rope winding support with an annular V-shaped outer periphery.

[0008] An adjustment mechanism is installed on the mounting base and acts on the support member to adjust the rotation angle of the support member.

[0009] The axis of rotation is located at the end of the two sets of support members that are close to each other.

[0010] Furthermore, the outer periphery of the pivot rod has a circular array of multiple connecting blocks, and mounting rods are connected between the multiple connecting blocks. One end of each of the multiple support members is rotatably fitted onto the mounting rod. Each mounting rod has two symmetrically distributed support members. The support members are generally elongated and the end connected to the mounting rod is circular. The circular end of the support member smoothly transitions to its surface.

[0011] Furthermore, the adjustment mechanism includes two driving members disposed on the pivot rod, the two driving members acting on two sets of support members respectively, and an adjustment component for driving the two driving members to move is installed on the mounting base. When the driving members move along the axis of the pivot rod, they drive the free ends of the corresponding multiple support members to move closer or further away from each other simultaneously.

[0012] Furthermore, the driving component is movably mounted on the pivot rod, and multiple sliding grooves are circularly arrayed on the opposite sides of the two driving components. Sliding blocks are slidably installed in the sliding grooves, and the free ends of the support components are respectively hinged to the multiple sliding blocks.

[0013] Furthermore, a rotating ring plate is rotatably mounted on the outer periphery of the driving component, and the adjusting assembly is used to drive the two rotating ring plates to move closer or further apart along the axis of the pivot rod.

[0014] Furthermore, the adjustment assembly includes a bidirectional screw that is horizontally and rotatably mounted on the mounting base. Two drive blocks are slidably mounted on the mounting base, and the two drive blocks are symmetrically threaded onto the bidirectional screw. The drive blocks have insertion holes. A connecting cylinder is mounted on the rotating ring plate. A sliding insert rod for insertion into the insertion hole is slidably mounted on the connecting cylinder. A positioning insert plate is slidably mounted on the sliding insert rod. Two positioning slots are provided on the connecting cylinder. An adjustment screw threaded through the positioning insert plate is rotatably mounted on the connecting cylinder.

[0015] Furthermore, two support plates are symmetrically and rotatably mounted on the mounting base. The two support plates are joined together to form a circular and sealed mounting groove. The end of the pivot rod away from the drive motor is mounted in the mounting groove through a bearing. The two support plates are connected by bolts.

[0016] Furthermore, a sleeve is connected to the mounting base by a ball joint, and a conical ring is constructed at one end of the sleeve. Multiple sliding plates are slidably installed on the outer periphery of the conical ring. A cleaning brush is installed on the side of the sliding plate near the conical ring. A sliding ring is movably sleeved on the outer periphery of the sleeve. One end of the multiple sliding plates is hinged to the sliding ring through a hinge rod. An adjusting ring threaded on the sleeve is rotatably installed at one end of the sliding plate.

[0017] Furthermore, the mounting base is horizontally rotatably mounted with a first pressure roller, and also includes a mounting frame. The mounting frame is horizontally rotatably mounted with a second pressure roller located above the first pressure roller. The mounting base has two symmetrical insertion slots. The mounting frame is vertically slidably mounted with an insertion plate for insertion into the insertion slot. The mounting frame is equipped with a positioning element to fix the mounting frame to the mounting base.

[0018] A method of using an adjustable winch, comprising the following steps:

[0019] S1. Based on the diameter of the cable to be pulled, the two sets of support members are driven to rotate around the connection point between them and the pivot rod by operating the adjustment mechanism, thereby changing the annular V-shaped opening angle of the rope winding bracket to match the diameter of the cable.

[0020] S2. Pass the free end of the cable around the working surface formed by the multiple support members of the winding mechanism in sequence, and manually wind it at least three times to achieve reliable traction by relying on friction.

[0021] S3. Start the drive motor to drive the pivot rod to rotate. The rotation of the pivot rod drives the winding mechanism to rotate, and the cable is wound and pulled. During this process, if the cable deviates, the angle of the support is adjusted by the adjustment mechanism to achieve dynamic adaptation.

[0022] Beneficial effects:

[0023] This invention drives the support members to rotate through an adjustment mechanism, changing the degree of the V-shaped angle formed between the two sets of support members. This makes it more convenient to use, eliminating the need to carry drums with different angles and further improving convenience. When pulling cables, it can effectively ensure the pulling effect and avoid problems such as tangled ropes and rope jams during cable installation and disassembly due to the cable being too thick or too thin and not matching the drum.

Detailed Implementation

[0039] The specific embodiments of the present invention will be described in detail below, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0040] like Figures 1 to 13As shown in the figure, an adjustable winch provided by an embodiment of the present invention includes:

[0041] The supporting mechanism 1 includes a mounting base 101, on which a drive motor 102 is mounted. A pivot rod 103 connected to the drive motor 102 is horizontally rotatably mounted on the mounting base 101. That is, the drive motor 102 serves as a power source, and the rotation shaft of the drive motor 102 is connected to one end of the pivot rod 103.

[0042] The winding mechanism 2 is installed on the pivot rod 103. The winding mechanism 2 has multiple rotatable support members 104. The multiple support members 104 are divided into two groups and symmetrically distributed on the pivot rod 103. Both groups of support members 104 are arranged in a circular array around the axis of the pivot rod 103 to form a rope winding support with an annular V-shaped outer periphery. That is to say, the overall shape of the two groups of support members 104 is similar to a funnel shape. The surface of the rope winding support is used to wind the cable.

[0043] Adjustment mechanism 3, installed on mounting base 101 and acting on support member 104, adjusts the rotation angle of support member 104. The two sets of support members 104 are positioned so that their ends are close to each other, forming the rotation axis. In use, the cable is first wound around the center of the rope-winding bracket surface, typically at least three turns, to ensure sufficient traction. One end of the cable is connected to the power cable. Then, drive motor 102 pre-starts, driving pivot rod 103 to rotate. During rotation, pivot rod 103 drives the winding mechanism 2 mounted on it, thus rotating the rope-winding bracket. If the cable is too thick, excessive mutual compression may occur during rotation. In this case, adjustment mechanism 3 can be used to drive support member 104 to rotate, changing the degree of the V-angle formed between the two sets of support members 104. Generally... If the cable is excessively squeezed against each other when the rope winch rotates, it indicates that the angle between the two sets of support members 104 is too small. The angle between the two sets of support members 104 can be widened by adjusting mechanism 3. If the cable is too thin, it is easy for the cable to become too loose and tangled when the rope winch rotates. In this case, the angle between the two sets of support members 104 needs to be reduced by adjusting mechanism 3. The advantage of a small winch is that it is easy to carry and transfer, making it convenient for cable installation or removal in different locations. It can use the appropriate thickness of cable to pull the cable to be installed or removed. With the adjustable angle rope winch, it is more convenient to use, eliminating the need to carry drums of different angles, further improving the convenience of the equipment. It can effectively ensure the pulling effect when pulling cables and avoid problems such as tangled ropes and jams caused by the cable being too thick or too thin and not matching the drum.

[0044] like Figures 1 to 6As shown, in some embodiments, the outer periphery of the pivot rod 103 is arranged in a circular array with multiple connecting blocks 4. Mounting rods 5 connect the multiple connecting blocks 4. One end of each of the multiple support members 104 is rotatably mounted on the mounting rod 5. Each mounting rod 5 has two symmetrically distributed support members 104. The support member 104 is generally elongated, with a circular end connected to the mounting rod 5. The circular end of the support member 104 smoothly transitions to its surface. Figure 6 and Figure 13 As shown, the surface of the connecting block 4 is rounded, and the support member 104 has a rounded end that smoothly transitions to the surface, making the inner wall of the V-shaped groove formed by the two sets of support members 104 smooth. After the cable is wound, the two sets of support members 104 effectively avoid damage to the surface of the cable due to the sharp edges when they rotate continuously, thus protecting the cable and effectively improving the service life of the cable.

[0045] like Figure 1 , Figure 3 and Figure 11 As shown, in some embodiments, the adjustment mechanism 3 includes two driving members 301 disposed on the pivot rod 103. The two driving members 301 act on two sets of support members 104 respectively. The mounting base 101 is equipped with an adjustment component 302 for driving the two driving members 301 to move. When the driving member 301 moves along the axis of the pivot rod 103, it drives the free ends of the corresponding multiple support members 104 to move closer or further away from each other at the same time. That is, when the adjustment mechanism 3 drives the driving member 301 to move along the axis of the pivot rod 103, the moving driving member 301 will cause the corresponding multiple support members 104 to rotate at the same time. Only the position of the driving member 301 needs to be adjusted to change the angle between the two sets of support members 104, which is more convenient and quick to use, and there is no need to adjust each support member 104 individually.

[0046] like Figure 1 , Figure 6 , Figure 11 and Figure 13 As shown, in some embodiments, the driving member 301 is movably mounted on the pivot rod 103. Multiple sliding grooves 303 are circularly arrayed on opposite sides of the two driving members 301. Sliding blocks 304 are slidably installed within the sliding grooves 303. The free ends of the support member 104 are respectively hinged to the multiple sliding blocks 304. Specifically, as shown... Figure 11As shown, the drive member 301 is generally circular. Since one end of the support member 104 is hinged to the mounting rod 5, when the drive member 301 moves, the movement of the drive member 301 will force the sliding block 304 to move in the sliding groove 303 under the action of the support member 104. At this time, multiple sliding blocks 304 will move closer or further away from each other along the axis of the drive member 301. The movement of the sliding block 304 changes the position of the support member 104 hinged on the sliding block 304, causing the support member 104 to rotate around the rotation axis of the mounting rod 5, thereby changing the rotation angle of multiple support members 104 at the same time.

[0047] like Figure 1 , Figure 2 and Figure 11 As shown, in some embodiments, a rotating ring plate 305 is rotatably mounted on the outer periphery of the driving member 301. The adjusting component 302 is used to drive the two rotating ring plates 305 to move closer or further away from each other along the axis of the pivot rod 103. That is, the rotating ring plates 305 move the same distance and in opposite directions under the action of the adjusting component 302, indicating that the two sets of support members 104 rotate at the same angle, ensuring that the angles of the two sets of support members 104 are consistent. This avoids the situation where one set of support members 104 rotates too much, which could cause the cable to easily deviate when winding the cable. After the rotating ring plate 305 moves along the axis of the pivot rod 103, the rotation of the two sets of support members 104 will drive the two driving members 301 to rotate simultaneously. During the cable pulling process, if the cable wound on the two sets of support members 104 is found to deviate, the position of the driving member 301 can be adjusted during the rotation of the two sets of support members 104 without stopping the machine to adjust the position of the cable.

[0048] like Figures 1 to 3 and Figure 11 As shown, in some embodiments, the adjusting assembly 302 includes a bidirectional screw 3021 horizontally and rotatably mounted on the mounting base 101. Two driving blocks 3022 are slidably mounted on the mounting base 101, and the two driving blocks 3022 are symmetrically threaded onto the bidirectional screw 3021. The driving blocks 3022 have insertion holes 3023. A connecting cylinder 3026 is mounted on the rotating ring plate 305. A sliding insert rod 3024 for insertion into the insertion hole 3023 is slidably mounted on the connecting cylinder 3026. A positioning insert plate 3025 is slidably mounted on the sliding insert rod 3024. Two positioning slots 3028 are provided on the connecting cylinder 3026. Specifically, the positioning insert plate 3025 has two free ends, and the number of positioning slots 3028 is four and they are distributed in pairs to improve the positioning effect. An adjusting screw 3027 threaded through the positioning insert plate 3025 is rotatably mounted on the connecting cylinder 3026. That is, as shown... Figure 3As shown, the sliding rod 3024 is not inserted into the socket 3023 at this time. The bottom of the rotating ring plate 305 is a certain distance away from the mounting base 101. Two support plates 6 are symmetrically and rotatably mounted on the mounting base 101. The two support plates 6 are joined to form a circular sealed mounting groove 7. The end of the pivot rod 103 away from the drive motor 102 is mounted in the mounting groove 7 through a bearing. The two support plates 6 are connected by bolts 8. The bolts 8 are existing bolts and nuts. When the bolts are removed from the two support plates 6... When disassembling, rotate the support plate 6 until it is horizontal. At this point, one end of the pivot rod 103 is suspended in the air. This makes it easier to wind the cable around the two sets of support members 104. It eliminates the need to hold one end of the cable and rotate it multiple times around the two sets of support members 104 to complete the winding. Simply hold the cable, stagger it to form a loop, and then directly slip it onto the two sets of support members 104. This is especially beneficial when the cable end is far from the equipment, effectively reducing the time spent winding the cable and completing the winding process. Next, the support plate 6 is rotated to align with the travel mounting groove 7, and then the support plate 6 is fixed by the bolts 8 to support the pivot rod 103 and ensure the stability of the pivot rod 103 during subsequent rotation. Then, the adjusting screw 3027 is rotated. Because the adjusting screw 3027 is threadedly engaged with the positioning insert plate 3025, the rotation of the adjusting screw 3027 will drive the positioning insert plate 3025 to move, thereby causing the positioning insert plate 3025 to disengage from the corresponding positioning slot 3028. Then, the sliding insert rod is moved. 3024, so that the two sliding rods 3024 are respectively inserted into the insertion hole 3023, and then the adjusting screw 3027 is tightened to insert the positioning plate 3025 into another positioning slot 3028. According to the actual situation, the bidirectional screw 3021 can be rotated to make the two driving blocks 3022 move away from or closer to each other, thereby driving the two rotating ring plates 305 to move simultaneously. In this way, the angle of the two sets of support members 104 can also be adjusted during the rotation of the pivot rod 103 without stopping the machine.

[0049] like Figure 1 , Figure 9 and Figure 10 As shown, when the cable is pulled by the cable, some impurities or dirt will adhere to the surface of the cable. To prevent these impurities from contacting the support 104 and getting stuck at the rotation point between the support 104 and the mounting rod 5, thus affecting the performance of the support 104 and increasing the frequency of cleaning the support 104, such as... Figure 10As shown, a sleeve 9 is ball-jointed to the mounting base 101. A conical ring 10 is constructed at one end of the sleeve 9. Multiple sliding plates 11 are slidably mounted on the outer periphery of the conical ring 10. A cleaning brush 12 is mounted on the side of the sliding plate 11 near the conical ring 10. The cleaning brush 12 is detachably connected to the sliding plate 11. A sliding ring 13 is movably fitted on the outer periphery of the sleeve 9 by means of bolts. One end of the multiple sliding plates 11 is hinged to the sliding ring 13 through a hinge rod 14. An adjusting ring 21 threaded onto the sleeve 9 is rotatably mounted on one end of the sliding plate 11. It should be noted that this cable cleaning device is selectively used according to the actual situation. For example, if it rains at the site where the cable is being pulled, causing rainwater and soil to mix together, in order to prevent wet soil from entering the gap between the support member 104 and the mounting rod 5 during cable pulling, After the soil dries, the support 104 may become stuck when rotating on the mounting rod 5. Therefore, before the cable is wound around the two sets of support 104, the cable should be passed through the multiple cleaning brushes 12 and pulled out from one end of the sleeve 9. If the contact force between the bristles of the cleaning brush 12 and the cable is insufficient, the adjusting ring 21 can be turned. When the adjusting ring 21 rotates, it will drive the sliding ring 13 to move. When the sliding ring 13 moves, it will force the multiple sliding plates 11 to move through the hinge rod 14. Since the sliding plates 11 move along the inclined surface of the conical ring 10, the multiple sliding plates 11 will cause the multiple cleaning brushes 12 to move closer or further away from each other when they move, so that the bristles on the cleaning brushes 12 can contact the cable. Since the sleeve 9 is connected by a ball joint and the inner diameter of the sleeve 9 and the conical ring 10 is much larger than the diameter of the cable, it will not affect the normal traction of the cable.

[0050] like Figure 1 , Figure 2 , Figure 7 , Figure 8 and Figure 12As shown, in some embodiments, a first pressure roller 15 is horizontally rotatably mounted on the mounting base 101, and a mounting frame 18 is also included. A second pressure roller 16 located above the first pressure roller 15 is horizontally rotatably mounted on the mounting frame 18. Two insertion slots 17 are symmetrically formed on the mounting base 101. An insertion plate 19 for insertion into the insertion slot 17 is vertically slidably mounted on the mounting frame 18. A positioning element 20 is mounted on the mounting frame 18 to fix the mounting frame 18 to the mounting base 101. Specifically, this application does not impose specific limitations on the structure of the positioning element 20. It can be any limiting structure that can satisfy the present application to install the mounting bracket 18 on the mounting base 101. In this embodiment, there are two positioning members 20. The mounting bracket 18 has a mounting cavity 23, which extends into the insertion plate 19. The two opposite sides of the insertion plate 19 are horizontally slidably equipped with first wedge plates 24. The two opposite sides of the insertion groove 17 are provided with a plurality of wedge grooves arranged in an array along its length direction. A spring piece 26 is installed between the first wedge plate 24 and the insertion plate 19. A connecting rod 27 is vertically constructed on the top of the first wedge plate 24. The opposite side of the connecting rod 27 is constructed with a... A second wedge plate 28 is provided. A drive rod 22 is vertically inserted into the top of the mounting frame 18. One end of the drive rod 22, located inside the mounting cavity 23, has a concave execution plate 25. The two top ends of the execution plate 25 are inclined surfaces for contacting the second wedge plate 28. Specifically, preferably, a motor can be installed on the mounting base 101. The motor drives the first pressure roller 15 to rotate to assist the cable traction. When the cable is placed on the first pressure roller 15, the two insertion plates 19 on the mounting frame 18 are inserted into the two insertion slots 17. The first wedge plate 24 contacts the inclined surface of the wedge slot until the second pressure roller 16 presses down. Holding the cable on the first pressure roller 15, the first pressure roller 15 and the second pressure roller 16 can guide the movement. When the cable pulls the cable, it can assist in the cable recovery. When it is necessary to pull the cable out from between the first pressure roller 15 and the second pressure roller 16, the drive rod 22 is moved upward so that the two top ends of the actuator plate 25 contact the second wedge plate 28, so that the two second wedge plates 28 move closer to each other, thereby indirectly driving the two first wedge plates 24 to disengage from the wedge groove. This makes it easier to disassemble the mounting bracket 18 and facilitates the adjustment of the distance between the first pressure roller 15 and the second pressure roller 16 according to the diameter of the cable.

[0051] like Figures 1 to 13 As shown, a method of using an adjustable winch includes the following steps:

[0052] S1. Based on the diameter of the cable to be pulled, the two sets of support members 104 are driven to rotate around the connection point between them and the pivot rod 103 by operating the adjustment mechanism 3, thereby changing the annular V-shaped opening angle of the rope winding bracket to match the diameter of the cable.

[0053] S2. The free end of the cable is passed around the working surface formed by the multiple support members 104 of the winding mechanism 2 in sequence, and manually wound around at least three times to achieve reliable traction by relying on friction.

[0054] S3. Start the drive motor 102 to drive the pivot rod 103 to rotate. The rotation of the pivot rod 103 drives the winding mechanism 2 to rotate, and the cable is wound and pulled. During this process, if the cable deviates, the angle of the support member 104 is adjusted by the adjustment mechanism 3 to achieve dynamic adaptation.

[0055] The above-disclosed embodiments are merely a few specific examples of the present invention. However, the embodiments of the present invention are not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.

3. A method for using an adjustable winch, characterized in that, Using an adjustable winch as described in any one of claims 1-2, the following steps are included: S1. According to the diameter of the cable to be pulled, by operating the adjustment mechanism (3), drive the two sets of support members (104) to rotate around the connection point with the pivot rod (103), thereby changing the annular V-shaped opening angle of the rope winding bracket to match the diameter of the cable. S2. The free end of the cable is passed around the working surface formed by the multiple support members (104) of the winding mechanism (2) in sequence, and manually wound around at least three times to achieve reliable traction by relying on friction. S3. Start the drive motor (102) to drive the pivot rod (103) to rotate. The rotation of the pivot rod (103) drives the winding mechanism (2) to rotate, and the cable is wound and pulled. During this process, if the cable deviates, the angle of the support (104) is adjusted by the adjustment mechanism (3) to achieve dynamic adaptation.
