Technical Field

[0001] The present application relates to the field of insulating pull rod assembly technology, and in particular to an insulating pull rod assembly device. Background Art

[0002] Insulating pull rods are important tools for the safe operation of high-voltage equipment in power systems. Their core function is to achieve electrical isolation between live operations and operators through insulating materials, thereby ensuring equipment and personal safety.

[0003] Insulated pull rods consist of a working head, an insulating rod, and a handle. These three parts need to be assembled during production. However, the current assembly process still relies on manual labor, resulting in low efficiency.

[0004] The patent document with publication number CN217114133U discloses an insulating pull rod installation device, and the patent document with publication number CN110416010B discloses an insulating pull rod assembly tool. Although the technical solutions corresponding to these two patent documents can improve the assembly efficiency of insulating pull rods through equipment, only one insulating pull rod can be assembled at a time, and the degree of manual participation is still high, and the assembly efficiency still needs to be improved. Summary of the Invention

[0005] In order to further improve the assembly efficiency of insulating pull rods, the present application provides an insulating pull rod assembly device.

[0006] The present application provides an insulating pull rod assembly device that adopts the following technical solution:

[0007] An insulating pull rod assembly device, comprising an annular pulley, a driving mechanism, a clamping mechanism and a friction plate; the driving mechanism is used to drive the pulley to rotate in an annular manner; the clamping mechanism is provided in plurality, and the plurality of clamping mechanisms are arranged at intervals along the length direction of the pulley; the clamping mechanism comprises a first clamping assembly and two second clamping assemblies, the first clamping assembly being used to clamp the insulating rod; the two second clamping assemblies are respectively provided on both sides of the first clamping assembly, and the two second clamping assemblies are respectively used to clamp the working head and the handle; the first clamping assembly comprises a first mounting assembly A seat, two first clamping blocks and two half rings, the two first clamping blocks are movably mounted on the first mounting seat, and the two half rings are respectively slidably connected to the mutually adjacent surfaces of the two first clamping blocks; when the two half rings clamp the insulating rod, they abut against each other to form a friction ring; the central axis of the friction ring is collinear with the movable central axis of the half ring; counterweights are provided at both ends of the half ring; the friction plate is provided above the first clamping assembly, and the lower surface of the friction plate is used for the friction ring to abut; the second clamping assembly is slidably connected to the pulley along the width direction of the pulley.

[0008] By adopting the above technical solution, when assembling the insulating pull rod, the insulating rod, working head, and handle are loaded at one end of the pulley. The insulating rod is first clamped by the first clamping assembly, and the working head and handle are clamped by two second clamping assemblies in the same clamping mechanism. The pulley then drives the clamping mechanism forward. During this movement, the friction ring holding the insulating rod abuts the lower surface of the friction plate. Because the half ring is slidably connected to the first clamping block, the friction ring, with the cooperation of the friction plate, can drive the insulating rod to rotate about its own central axis. During this rotation, the working head and the insulating rod are tightened together, and the handle and the insulating rod are tightened together, completing the assembly of the insulating pull rod. After the clamping mechanism moves away from the friction plate, the first and second clamping mechanisms are released, and the assembled insulating pull rod can be unloaded.

[0009] By utilizing the above solution, even with manual participation, only the loading and unloading work needs to be completed, which reduces the manual participation and enables batch assembly of insulating pull rods with high assembly efficiency.

[0010] Optionally, the first clamping assembly is detachably connected to the pulley; the friction plate is provided with a lifting mechanism, and the lifting mechanism is used to control the friction plate to rise or fall.

[0011] By adopting the above technical solution, the first clamping mechanism of the corresponding friction ring with different sizes can be replaced according to the different outer diameters of the insulating rod to be assembled, and the height of the friction plate can be adjusted according to the outer diameter of the friction ring, so that the assembly device is suitable for assembling insulating pull rods of various sizes, thereby improving the flexibility of the assembly device.

[0012] Optionally, both of the first clamping blocks are electromagnets; when the first clamping assembly moves to be opposite to the friction plate, both of the first clamping blocks are connected to the power supply, and the opposite surfaces of the two first clamping blocks attract each other.

[0013] By adopting the above technical solution, the first clamping assembly automatically clamps the insulating rod when it moves to be opposite to the friction plate, without the need for a separate driving component for driving the clamping, and the operation is simple and convenient.

[0014] Optionally, the second clamping assembly includes a second mounting seat and two second clamping blocks, and the two second clamping blocks are movably connected to the second mounting seat; the two second clamping blocks are electromagnets, and when the first clamping block is connected to the power supply, the corresponding second clamping block is connected to the power supply, and the relative surfaces of the two second clamping blocks attract each other.

[0015] By adopting the above technical solution, during the assembly process, the working head and the handle are automatically clamped by the second clamping assembly, without the need for a separate driving member for driving the clamping, and the operation is simple and quick.

[0016] Optionally, a first abutting portion is provided on both sides of the pulley, and a first elastic member is provided between the second clamping assembly and the first abutting portion, and the first elastic member is used to force the second clamping assembly to move toward the direction of the first clamping assembly.

[0017] By adopting this technical solution, when assembling an insulating rod, the distance between the second clamping assembly and the first clamping assembly can be adjusted according to the length of the insulating rod, making the assembly device suitable for insulating rods of different lengths and improving its usability. Due to the presence of the first elastic member, the working head and the handle can respectively abut against both ends of the insulating rod for insulating rods of different lengths, ensuring efficient assembly.

[0018] Optionally, the pulley is provided with a support rod, the support rod is provided with a movable groove, and the second mounting seat is provided with a movable block that slides and cooperates with the movable groove.

[0019] By adopting the above technical solution, the cooperation between the movable block and the movable groove is utilized to guide and limit the movement of the second clamping assembly relative to the pulley, thereby ensuring the stability and reliability of the movement of the second clamping assembly relative to the pulley.

[0020] Optionally, it also includes two guide rails, which are arranged in a ring shape, and the pulley is located in a virtual ring formed by the guide rails; the two guide rails are respectively arranged on both sides of the friction plate, and the outer side of the guide rails is used for the second mounting seat to abut; the guide rail includes an upper guide part located above the pulley, a transition guide part located at both ends of the pulley and a lower guide part located below the pulley; the upper guide part, the transition guide part and the lower guide part are connected to each other; from one end of the pulley to the other end, the distance between the two upper guide parts first decreases, then remains unchanged and then increases; the distance between the two transition guide parts is consistent, and the distance between the two lower guide parts is consistent; when the distance between the two second clamping assemblies is less than the distance between the two transition guide parts, the first clamping block is connected to the power supply, and the second clamping block is connected to the power supply.

[0021] By adopting the above technical solution, when the driving mechanism drives the pulley to rotate, the pulley drives the clamping mechanism to rotate together. At the positions of the lower guide part and the transition guide part, the two second clamping components in the same clamping mechanism are respectively in contact with the outer sides of the two guide rails. The deformation of the first elastic part reaches the maximum, and the distance between the two second clamping components is the maximum. At this time, the first clamping block and the second clamping block are both disconnected from the power supply, there is no interaction force between the two first clamping blocks, and there is no interaction force between the two second clamping blocks. At this time, the parts to be assembled can be placed in the clamping mechanism, and the assembled insulating pull rod can also be taken out from the clamping mechanism.

[0022] After entering the upper guide part above the pulley from the transition guide part, since the distance between the two upper guide parts gradually decreases, the second clamping assembly moves toward the first clamping assembly under the elastic force of the first elastic member. At the same time, the first clamping block is connected to the power supply, the second clamping block is connected to the power supply, the first clamping assembly clamps the insulating rod, and the second clamping assembly clamps the working head and the handle.

[0023] Through the above structure, during the movement of the pulley, automatic clamping is achieved at the assembly position, and automatic relaxation is achieved at the loading and unloading positions. The structure is simple and the efficiency is high.

[0024] Optionally, one of the support rods corresponds to two of the second clamping assemblies in the same clamping mechanism; the bottom wall of the movable groove is provided with an electrical connection portion, which is used to be electrically connected to a power source, and the electrical connection portion is extended along the length direction of the movable groove; the first mounting seat is slidably connected to a first conductive portion along its own height direction; the second mounting seat is provided with a second conductive portion, and the second conductive portion is electrically connected to the second clamping block; the second mounting seat is connected to a guide rod on the side close to the first mounting seat, and when the second mounting seat moves in a direction close to the first mounting seat, the guide rod forces the first conductive portion to move in a direction close to the electrical connection portion until it abuts against the electrical connection portion; when the first conductive portion abuts against the electrical connection portion, the first clamping block is connected to the power supply; the first conductive portion is provided with a second elastic member, and the second elastic member is used to support the first conductive portion away from the bottom wall of the movable groove; when the clamping mechanism rotates upward, the first conductive portion abuts against the electrical connection portion, and the second conductive portion is electrically connected to the electrical connection portion.

[0025] By adopting the above technical solution, when the clamping mechanism moves to the upper guide part, under the elastic force of the first elastic member, the second clamping component moves toward the direction close to the first clamping component, and the second conductive part is electrically connected to the electrical connection part; the second clamping component approaches and drives the guide rod to move, and the guide rod forces the first conductive part to abut against the electrical connection part, that is, the first conductive part is electrically connected to the electrical connection part, thereby connecting the first clamping block to the power supply.

[0026] When the clamping mechanism moves to the position of the transition guide part and the lower guide part, under the action of the guide rail, the first elastic part is deformed, the distance between the second clamping assembly and the first clamping assembly reaches the maximum, and the second conductive part and the electrical connection part are disconnected; the second elastic part drives the first conductive part to reset, and the first conductive part and the electrical connection part are disconnected.

[0027] Optionally, a first spring is provided between the two first clamping blocks, and when the first spring is at its original length, a gap is formed between the two half rings for the insulating rod to pass through; a second spring is provided between the two second clamping blocks, and when the second spring is at its original length, a gap is formed between the two second clamping blocks for the insulating pull rod to pass through.

[0028] By adopting the above technical solution, after the connection between the first conductive part and the electrical connecting part is disconnected, and the connection between the second conductive part and the electrical connecting part is disconnected, the first spring forces the two first clamping blocks to move away from each other, and the second spring forces the two second clamping blocks to move away from each other, so as to form a gap for the insulating pull rod to be removed, which is convenient for the removal and unloading of the insulating pull rod, and also convenient for the loading of the working head, insulating rod and handle.

[0029] Optionally, a guide groove is provided on the surface of the friction plate facing the pulley, and the guide groove extends along the length direction of the friction plate. The two ends of the guide groove respectively pass through the two end surfaces of the friction plate, and the bottom wall of the guide groove is used for the friction ring to abut.

[0030] By adopting the above technical solution, the guide groove is used to guide and limit the rolling of the friction ring, thereby improving the stability of the movement of the first clamping assembly relative to the friction plate.

[0031] In summary, this application includes at least one of the following beneficial technical effects:

[0032] By providing a set of first clamping assemblies, two sets of second clamping assemblies, and friction plates, the first clamping assemblies clamp the insulating rod, while the two sets of second clamping assemblies clamp the working head and handle, respectively. As the pulley rotates, the friction plates and friction rings cooperate to drive the friction rings, which in turn drive the insulating rods, completing the threaded connection between the working head and the insulating rod, and the threaded connection between the handle and the insulating rod, thereby completing the assembly of the insulating rods. This method requires minimal manual intervention and can be assembled in batches, improving assembly efficiency of the insulating rods.

[0033] By arranging a first elastic member between the second clamping assembly and the first abutting portion, and arranging a guide rail outside the pulley, the shape of the guide rail and the cooperation of the first elastic member are used to control the distance between the second clamping assembly and the first clamping assembly at different positions, and at the same time control the clamping degree between the first clamping assembly and the second clamping assembly, the structure is simple and the operation is convenient;

[0034] By arranging a first spring between the two first clamping blocks and a second spring between the two second clamping blocks, after assembly is completed, the first spring forces the two first clamping blocks to move apart, and the second spring forces the two second clamping blocks to move apart, thereby facilitating loading before assembly and removing and unloading the insulating pull rod after assembly is completed.

DETAILED DESCRIPTION

[0045] The following is combined with Figure 1-9 It should be noted that the drawings in the specification are mainly used to clearly illustrate the principles of the main technical solutions of this application, and the proportions are somewhat different from the actual objects, and some structures that do not directly affect the understanding of the technical solutions are not drawn.

[0046] The embodiment of the present application discloses an insulating pull rod assembly device for assembling an insulating pull rod, wherein the insulating pull rod comprises a working head, an insulating rod, and a handle, wherein the working head is threadedly connected to the insulating rod, and the handle is threadedly connected to the insulating rod. Example 1

[0047] Reference Figure 1 An insulating pull rod assembly device includes a frame 1, an annular pulley 2, a driving mechanism, a clamping mechanism 3, a friction plate 4 and a guide rail 5.

[0048] The pulley 2 and the driving mechanism are both arranged on the frame 1, and the driving mechanism is used to drive the pulley 2 to rotate. A plurality of clamping mechanisms 3 are provided, and the plurality of clamping mechanisms 3 are arranged at equal intervals along the length direction of the pulley 2.

[0049] Reference Figure 2 The clamping mechanism 3 includes a first clamping assembly 6 and a second clamping assembly 7. The first clamping assembly 6 is positioned in the middle of the pulley 2 and moves with the pulley 2, clamping the insulating rod. Two sets of second clamping assemblies 7 are provided, each slidably connected to the pulley 2 along its width. The first clamping assembly 6 is located between the two sets of second clamping assemblies 7, which are used to clamp the working head and the handle, respectively.

[0050] Reference Figure 2 and Figure 3 Specifically, the first clamping assembly 6 includes a first mounting seat 61, two first clamping blocks 62 and two half rings 63. A first slide groove 611 is provided on the surface of the first mounting seat 61 away from the pulley 2, and the first slide groove 611 extends along the length direction of the pulley 2. The first clamping block 62 has a first sliding portion 621, and the first sliding portion 621 slides and cooperates with the first slide groove 611. A first spring 64 is provided between the two first sliding portions 621, and the two ends of the first spring 64 are respectively connected to the two first sliding portions 621. When the first spring 64 is at its original length, the two first sliding portions 621 respectively abut against the two groove end walls of the first slide groove 611.

[0051] The two half-rings 63 are connected to the two corresponding first clamping blocks 62. The first clamping blocks 62 are provided with an arc-shaped cavity 622, the two ends of which extend through the two adjacent end surfaces of the first clamping blocks 62. The half-rings 63 are slidably connected in the arc-shaped cavity 622, and the central axis of the arc-shaped cavity 622 is collinear with the central axis of the half-rings 63. When the two first clamping blocks 62 are brought into contact with each other, the two half-rings 63 abut against each other to form a complete circular ring, which is designated as a friction ring 67. Counterweights 631 are provided at both ends of the half-rings 63, so that in a natural state, one end of the half-ring 63 is located outside the arc-shaped cavity 622 under the action of gravity, thereby facilitating the separation of the two first clamping blocks 62.

[0052] Reference Figure 1 and Figure 4 The friction plate 4 is fixed to the frame 1 and extends along the length of the pulley 2. The friction plate 4 is located above the first clamping assembly 6. The lower surface of the friction plate 4 is used for abutment by the friction ring 67. When the pulley 2 drives the first clamping assembly 6 to move, the friction ring 67 rotates under the action of the friction plate 4, thereby driving the insulating rod to rotate, tightening the working head and the insulating rod, and tightening the handle and the insulating rod.

[0053] In this embodiment, a guide groove 41 is defined on the surface of the friction plate 4 facing the pulley 2. The guide groove 41 extends along the length of the pulley 2, with both ends of the guide groove 41 penetrating the two end surfaces of the friction plate 4. The bottom wall of the guide groove 41 is designed to abut against the friction ring 67. This guide groove 41 provides a certain degree of guidance and limitation for the movement path of the friction ring 67, ensuring the stability and reliability of the movement of the first clamping assembly 6 with the pulley 2.

[0054] The two first clamping blocks 62 are electromagnets. When the first clamping assembly 6 moves relative to the friction plate 4, the two first clamping blocks 62 are connected to the power supply 85, causing the opposing surfaces of the two first clamping blocks 62 to attract each other. This attraction forces the two first clamping blocks 62 toward each other, clamping the insulating rod. After the first clamping assembly 6 moves away from the friction plate 4, the first clamping blocks 62 are disconnected from the power supply 85. The elastic force of the first spring 64 causes the two first clamping blocks 62 to move away from each other, creating a gap between the two half-rings 63 for the insulating rod to escape, facilitating the removal of the assembled insulating pull rod. The structure of how the first clamping blocks 62 are energized and de-energized as the pulley 2 moves will be further described below.

[0055] Reference Figure 5 The second clamping assembly 7 includes a second mounting base 71 and two second clamping blocks 72. A second chute 711 is defined on the surface of the second mounting base 71 facing away from the pulley 2. The second chute 711 extends along the length of the pulley 2. The second clamping block 72 has a second sliding portion 721 that slides in engagement with the second chute 711. A second spring 73 is disposed between the two second sliding portions 721. When the second spring 73 is at its original length, the two second sliding portions 721 abut against the two end walls of the second chute 711.

[0056] Both second clamping blocks 72 are electromagnets. When the first clamping block 62 is connected to the power source 85, the corresponding second clamping blocks 72 in the same clamping mechanism 3 are also connected to the power source 85. The opposing surfaces of the two second clamping blocks 72 attract each other, thereby clamping the working head and handle. The structure of how the second clamping blocks 72 are energized and de-energized in response to the movement of the pulley 2 will be further described below.

[0057] Reference Figure 1 、 Figure 2 and Figure 6 The pulley 2 is provided with a plurality of support rods 8, which extend along the length of the pulley 2 and are arranged at equal intervals along the length of the pulley 2. The plurality of support rods 8 correspond one to one with the plurality of clamping mechanisms 3. The first mounting seat 61 is fixed to the support rods 8.

[0058] A movable groove 81 is formed on the surface of the support rod 8 facing away from the pulley 2 , and the second mounting seat 71 is provided with a movable block 712 that is slidably engaged with the movable groove 81 .

[0059] Reference Figure 6 and Figure 7 A first abutment portion 82 is provided on both sides of the pulley 2, and a first elastic member 83 is provided between the second clamping assembly 7 and the first abutment portion 82. The first elastic member 83 is used to force the second clamping assembly 7 to move toward the first clamping assembly 6. In this embodiment, the first elastic member 83 is a spring, and the two ends of the support rod 8 serve as the first abutment portion 82. One end of the first elastic member 83 is connected to the end wall of the movable groove 81, and the other end is connected to the second mounting seat 71.

[0060] The following details the specific structure and principle of the first clamping block 62 and the second clamping block 72 turning on and off the power supply 85 in the process of moving with the pulley 2:

[0061] Reference Figure 1 and Figure 8 Two guide rails 5 are provided, each of which is annular and fixed to the frame 1. The pulley 2 is located within the virtual ring formed by the two guide rails 5. The two guide rails 5 are symmetrically arranged on either side of the friction plate 4 about the central axis of the friction plate 4. The outer side of the guide rails 5 is used for abutment by the second mounting seat 71. Therefore, with the cooperation of the first elastic member 83, the guide rails 5 control the movement path of the second clamping assembly 7. In other words, the distance between the second clamping assembly 7 and the first clamping assembly 6 varies when the pulley 2 reaches different positions.

[0062] Specifically, the guide rail 5 includes an upper guide portion 51 located above the pulley 2, transition guide portions 52 located at both ends of the pulley 2, and a lower guide portion 53 located below the pulley 2. The upper guide portion 51, transition guide portion 52, and lower guide portion 53 are interconnected. From one end of the pulley 2 to the other, the distance between the two upper guide portions 51 first decreases, then remains constant, and then increases. The distance between the two transition guide portions 52 remains constant, and the distance between the two lower guide portions 53 remains constant.

[0063] Reference Figure 7 The bottom of the movable groove 81 is provided with an electrical connection portion 84. A power source 85 is embedded within the support rod 8, and the electrical connection portion 84 is electrically connected to the power source 85. The electrical connection portion 84 extends along the length of the movable groove 81, and its length is less than the distance between the two lower guide portions 53. The second sliding portion is provided with a second conductive portion, which is electrically connected to the second clamping block 72. When the second guide portion contacts the electrical connection portion 84, the second clamping block 72 is connected to the power source 85.

[0064] When the second clamping assembly 7 moves to the upper guide portion 51 , the two second clamping assemblies 7 in the same clamping mechanism 3 both approach the corresponding first clamping assembly 6 , and the second conductive portion is electrically connected to the electrical connection portion 84 , so that the second clamping block 72 is connected to the power supply 85 .

[0065] Reference Figure 3 and Figure 7 The bottom surface of the first mounting seat 61 defines a conductive slot 612, which extends along the height of the first mounting seat 61. A first conductive portion 65 is slidably connected to the conductive slot 612 along the height of the first mounting seat 61. The first mounting seat 61 defines a through-hole 613, with both ends of the through-hole 613 extending through two mutually spaced side walls of the first mounting seat 61, communicating with the conductive slot 612. A gap is formed between the upper end surface of the first conductive portion 65 and the bottom wall of the conductive slot 612, and a gap is formed between the lower end surface of the first conductive portion 65 and the bottom wall of the movable slot 81.

[0066] The movable slot 81 is provided with a second elastic member 66, which is used to propel the first conductive portion 65 away from the bottom wall of the movable slot 81. In this embodiment, the second elastic member 66 is a spring and is sleeved outside the first conductive portion 65. A second abutment portion 651 is integrally formed at the upper end of the first conductive portion 65. The second abutment portion 651 is used to abut and connect with the upper end of the second elastic member 66. The other end of the second elastic member 66 is connected to the bottom wall of the movable slot 81.

[0067] Reference Figure 7 A guide rod 713 is fixedly connected to the side of the second mounting seat 71 that is close to the first mounting seat 61. The end of the guide rod 713 that is away from the second mounting seat 71 has a guide surface 714. The guide surface 714 is used to abut the upper end surface of the first conductive portion 65. When the second mounting seat 71 approaches the first mounting seat 61, the guide surface 714 is inserted into the insertion gap through the opening 613. Under the action of the guide surface 714, the first conductive portion 65 moves toward the bottom wall of the movable groove 81 and eventually abuts against the bottom wall, thereby connecting the first clamping block 62 to the power supply 85. It is understood that the end of the guide rod 713 that is away from the second mounting seat 71 should be made of a conductive material, and the portion of the first mounting seat 61 between the first clamping block 62 and the first conductive portion 65 should also be made of a conductive material.

[0068] Reference Figure 1 Furthermore, a conveyor belt 9 is provided below the pulley 2. The conveyor belt 9 is used to transport the working head, insulating rod and handle to be assembled to one end of the pulley 2. The assembled insulating rod will also fall from the other end of the pulley 2 onto the conveyor belt 9 and be transported out of the assembly station.

[0069] It is understandable that, in another embodiment, a robot arm may be provided on the frame 1 for loading the working head, insulating rod and handle, thereby further reducing manual intervention.

[0070] The implementation principle of Example 1 is as follows: When assembling the insulating pull rod, a conveyor belt 9 is used to transport the working head, insulating rod, and handle to one end of the pulley 2. The worker places the insulating rod in the first clamping assembly 6, and the working head and handle are placed in the two second clamping assemblies 7 on both sides of the first clamping assembly 6. The pulley 2 drives the clamping mechanism 3 toward the friction plate 4. After the clamping mechanism 3 moves to the position of the upper guide portion 51, as the pulley 2 moves and the shape of the guide rail 5 changes, the second clamping assembly 7 moves toward the first clamping assembly 6. During this movement, the second clamping block 72 is connected to the power supply 85, and the second clamping assembly 7 clamps the working head and handle. The first clamping block 62 is connected to the power supply 85 under the action of the guide rod 713, and the second clamping assembly 7 clamps the insulating rod.

[0071] Afterwards, the clamping mechanism 3 reaches the bottom of the friction plate 4. During the movement of the pulley 2, the friction ring 67 is driven to move. The friction ring 67 rotates with the cooperation of the friction plate 4, driving the insulating rod to rotate, so that the working head and the insulating rod are tightened, and the handle and the insulating rod are tightened, completing the assembly of the insulating pull rod.

[0072] After the clamping mechanism 3 leaves the upper guide portion 51 and moves to the lower guide portion 53, the distance between the two sets of second clamping assemblies 7 reaches its maximum under the action of the two guide rails 5. The second clamping assemblies 7 are released, and the friction ring 67 rotates under the action of the counterweight 631 until the end exposes the arc-shaped cavity 622. The two second clamping blocks 72 move away from each other under the action of the second spring 73, and the second clamping assembly 7 is released. The assembled insulating pull rod falls onto the conveyor belt 9. The clamping mechanism 3 then rotates back to the loading position with the pulley 2, and the above process is repeated. Example 2

[0073] Reference Figure 9 The difference between this embodiment and embodiment 1 is that the first clamping assembly 6 is detachably connected to the pulley 2. The friction plate 4 is provided with a lifting mechanism 42, which is used to control the friction plate 4 to rise or fall.

[0074] Specifically, the first mounting base 61 is connected to the support rod 8 by bolts. The lifting mechanism 42 is a cylinder or a hydraulic cylinder, so as to facilitate the assembly of insulating rods with different thicknesses.

[0075] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
