Technical Field

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

[0002] The insulating rod is an important tool for safely operating high-voltage equipment in the power system. Its core function is to achieve electrical isolation between live operation and operators through insulating materials, thereby ensuring the safety of equipment and personnel.

[0003] The insulating rod is composed of a working head, an insulating rod, and a handle. When producing the insulating rod, these three parts need to be assembled. In the existing actual production, the assembly still relies on manual labor, resulting in low efficiency.

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

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

[0006] The insulating rod assembly device provided by the present application adopts the following technical solutions: An insulating rod assembly device includes an annular pulley, a driving mechanism, a clamping mechanism, and a friction plate; the driving mechanism is used to drive the annular rotation of the pulley; a plurality of clamping mechanisms are provided, and the plurality of clamping mechanisms are arranged at intervals along the length direction of the pulley; the clamping mechanism includes a set of first clamping components and two sets of second clamping components, the first clamping component is used to clamp the insulating rod; the two sets of second clamping components are respectively arranged on both sides of the first clamping component, and the two sets of second clamping components are respectively used to clamp the working head and the handle; the first clamping component includes a first mounting seat, two first clamping blocks, and two half-rings, the two first clamping blocks are both movably installed on the first mounting seat, and the two half-rings are respectively slidably connected to the mutually approaching 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 coincides with the movable central axis of the half-ring; counterweights are arranged at both ends of the half-ring; the friction plate is arranged above the first clamping component, and the lower surface of the friction plate is used for the friction ring to abut against; the second clamping component is slidably connected to the pulley along the width direction of the pulley.

[0007] By adopting the above technical solution, when assembling the insulating pull rod, the insulating rod, the working head and the handle are loaded at one end of the pulley. First, the insulating rod is clamped by the first clamping assembly, and the working head and the handle are respectively clamped by two second clamping assemblies in the same clamping mechanism; then the pulley drives the clamping mechanism to move forward. During the movement, the friction ring clamping the insulating rod abuts against the lower surface of the friction plate. Since the semi-ring is slidably connected to the first clamping block, the friction ring can drive the insulating rod to rotate around its own central axis with the cooperation of the friction plate. During the rotation, the working head and the insulating rod are screwed together, and the handle and the insulating rod are screwed together to complete the assembly of the insulating pull rod. After the clamping mechanism moves away from the friction plate, the first clamping mechanism and the second clamping mechanism are released, and the assembled insulating pull rod can be unloaded.

[0008] By using the above solution, even if there is human participation, only the loading and unloading work needs to be completed, the human participation is less, and the batch assembly of the insulating pull rod can be realized, and the assembly efficiency is relatively high.

[0009] Optionally, the first clamping assembly is detachably connected to the pulley; the friction plate is provided with a lifting mechanism for controlling the friction plate to rise or fall.

[0010] By adopting the above technical solution, according to the different outer diameters of the insulating rods to be assembled, the corresponding first clamping mechanisms with different-sized friction rings can be replaced, 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 applicable to the assembly of insulating pull rods of various sizes and improves the flexibility of use of the assembly device.

[0011] 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 in an on state with the power supply, and the opposite surfaces of the two first clamping blocks attract each other.

[0012] 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, and there is no need to additionally provide a driving part for driving and clamping, and the operation is simple and convenient.

[0013] Optionally, the second clamping assembly includes a second mounting seat and two second clamping blocks, and both of the second clamping blocks are movably connected to the second mounting seat; both of the second clamping blocks are electromagnets. When the first clamping block is connected to the power supply, the corresponding second clamping block is connected to the power supply, and the opposite surfaces of the two second clamping blocks attract each other.

[0014] By adopting the above technical solution, during the assembly process, the working head and the handle are automatically clamped by the second clamping assembly, eliminating the need for an additional driving member for driving and clamping, and the operation is simple and fast.

[0015] Optionally, first abutting portions are provided on both sides of the pulley, and a first elastic member is provided between the second clamping assembly and the first abutting portion. The first elastic member is used to force the second clamping assembly to move towards the first clamping assembly.

[0016] By adopting the above technical solution, when assembling the insulating pull 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 applicable to insulating pull rods of different lengths and improving the flexibility of use of the assembly device. Due to the presence of the first elastic member, for insulating pull rods of different lengths, the working head and the handle can respectively abut against both ends of the insulating rod to ensure the effective progress of the assembly.

[0017] 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 slidably cooperates with the movable groove.

[0018] By adopting the above technical solution, the cooperation between the movable block and the movable groove is used to guide and limit the movement of the second clamping assembly relative to the pulley, ensuring the stability and reliability of the movement of the second clamping assembly relative to the pulley.

[0019] Optionally, it further includes two guide rails. The guide rails are arranged in a ring shape, and the pulley is located within the virtual ring formed by the guide rails; the two guide rails are respectively arranged on both sides of the friction plate, and the outer sides of the guide rails are for the second mounting seat to abut against; the guide rails include an upper guide portion located above the pulley, transition guide portions located at both ends of the pulley, and a lower guide portion located below the pulley; the upper guide portion, the transition guide portions, and the lower guide portion are connected to each other; from one end of the pulley to the other end, the distance between the two upper guide portions first decreases, then remains unchanged, and then increases; the distance between the two transition guide portions is the same, and the distance between the two lower guide portions is the same; when the distance between the two second clamping assemblies is less than the distance between the two transition guide portions, the first clamping block is connected to the power supply, and the second clamping block is connected to the power supply.

[0020] By adopting the above technical solution, during the process of the driving mechanism driving the pulley to rotate, the pulley drives the clamping mechanism to rotate together. At the positions of the lower guiding part and the transition guiding part, the two second clamping components in the same clamping mechanism respectively abut against the outer sides of the two guiding rails. The deformation amount of the first elastic member reaches the maximum, and the distance between the two second clamping components is the largest. At this time, both the first clamping block and the second clamping block are disconnected from the power supply, there is no mutual force between the two first clamping blocks, and there is no mutual force between the two second clamping blocks. At this time, the parts to be assembled can be placed in the clamping mechanism, or the assembled insulating pull rod can be taken out from the clamping mechanism.

[0021] After entering the upper guiding part above the pulley from the transition guiding part, since the distance between the two upper guiding parts gradually decreases first, under the elastic force of the first elastic member, the second clamping component moves towards the direction close to the first clamping component. 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 component clamps the insulating rod, and the second clamping component clamps the working head and the handle.

[0022] Through the above structure, during the movement of the pulley, automatic clamping is realized at the assembly position, and automatic relaxation is realized at the feeding and discharging positions. The structure is simple and the efficiency is relatively high.

[0023] Optionally, one of the support rods corresponds to the two second clamping components in the same clamping mechanism; an electrical connection part is arranged on the bottom wall of the moving groove, and the electrical connection part is used for electrically connecting with the power supply and extends along the length direction of the moving groove; the first mounting seat is slidably connected with a first conductive part along its own height direction; the second mounting seat is provided with a second conductive part, and the second conductive part is electrically connected with the second clamping block; a guiding rod is connected to one side of the second mounting seat close to the first mounting seat. When the second mounting seat moves towards the direction close to the first mounting seat, the guiding rod forces the first conductive part to move towards the direction close to the electrical connection part until it abuts against the electrical connection part; when the first conductive part abuts against the electrical connection part, the first clamping block is connected to the power supply; the first conductive part is provided with a second elastic member, and the second elastic member is used for pushing the first conductive part away from the bottom wall of the moving groove; when the clamping mechanism rotates upwards, the first conductive part abuts against the electrical connection part, and the second conductive part is electrically connected with the electrical connection part.

[0024] By adopting the above technical solution, when the clamping mechanism moves to the upper guiding part, under the elastic force of the first elastic member, the second clamping assembly moves towards the first clamping assembly, and the second conductive part is electrically connected to the electrical connection part; while the second clamping assembly moves closer, it drives the guiding rod to move, and the guiding 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 enabling the first clamping block to be connected to the power supply.

[0025] When the clamping mechanism moves to the position of the transition guiding part and the lower guiding part, under the action of the guiding rail, the first elastic member deforms, the distance between the second clamping assembly and the first clamping assembly reaches the maximum, and the connection between the second conductive part and the electrical connection part is disconnected; the second elastic member drives the first conductive part to reset, and the connection between the first conductive part and the electrical connection part is disconnected.

[0026] Optionally, a first spring is arranged between the two first clamping blocks. When the first spring is in its original length, a gap for the insulating rod to pass through is formed between the two half rings; a second spring is arranged between the two second clamping blocks. When the second spring is in its original length, a gap for the insulating pull rod to pass through is formed between the two second clamping blocks.

[0027] By adopting the above technical solution, after the connection between the first conductive part and the electrical connection part is disconnected and the connection between the second conductive part and the electrical connection 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 escape, facilitating the escape and blanking of the insulating pull rod, and also facilitating the feeding of the working head, insulating rod and handle.

[0028] Optionally, a guiding groove is formed on the surface of the friction plate facing the pulley. The guiding groove extends along the length direction of the friction plate, and both ends of the guiding groove penetrate through the two end faces of the friction plate respectively. The bottom wall of the guiding groove is used for the friction ring to abut against.

[0029] By adopting the above technical solution, the guiding groove is used to guide and limit the rolling of the friction ring, improving the stability of the movement of the first clamping assembly relative to the friction plate.

[0030] In summary, the present application includes at least one of the following beneficial technical effects: By setting a group of first clamping components, two groups of second clamping components and a friction plate, the insulating rod is clamped by the first clamping components, and the working head and the handle are respectively clamped by the two groups of second clamping components. During the rotation of the pulley, the cooperation between the friction plate and the friction ring is utilized to drive the friction ring to rotate, and then drive the insulating rod to rotate, completing the threaded connection between the working head and the insulating rod, and completing the threaded connection between the handle and the insulating rod, thereby completing the assembly of the insulating pull rod. The manual participation is low and batch assembly can be carried out, improving the assembly efficiency of the insulating pull rod; By arranging a first elastic member between the second clamping component 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 components at different positions between the first clamping components, and at the same time control the clamping degree of the first clamping component and the second clamping component. The structure is simple and the operation is convenient; By arranging a first spring between two first clamping blocks and a second spring between two second clamping blocks. After the assembly is completed, the first spring forces the two first clamping blocks to move away, and the second spring forces the two second clamping blocks to move away, so as to facilitate the feeding before assembly and the discharging of the insulating pull rod after the assembly is completed.

Detailed implementation manners

[0041] The following further describes the present application in detail with reference to Figures 1-9 It should be noted that the accompanying drawings in the specification are mainly used to clearly show the principle of the main technical solution of the present application. There is a certain deviation between the scale and the actual object, and some structures that do not directly affect the understanding of the technical solution are not drawn.

[0042] An insulating pull rod assembly device disclosed in an embodiment of the present application is used for assembling an insulating pull rod. The insulating pull rod includes a working head, an insulating rod, and a handle. The working head is threadedly connected to the insulating rod, and the handle is threadedly connected to the insulating rod. Embodiment 1

[0043] Referring to 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 guiding rail 5.

[0044] Both the pulley 2 and the driving mechanism are 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.

[0045] Referring to Figure 2 , the clamping mechanism 3 includes a first clamping assembly 6 and a second clamping assembly 7. The first clamping assembly 6 is arranged at the middle position of the pulley 2 and moves together with the pulley 2. The first clamping assembly 6 is used to clamp the insulating rod. Two groups of second clamping assemblies 7 are provided. The two groups of second clamping assemblies 7 are both slidably connected to the pulley 2 along the width direction of the pulley 2. The first clamping assembly 6 is located between the two groups of second clamping assemblies 7. The two groups of second clamping assemblies 7 are respectively used to clamp the working head and the handle.

[0046] Referring toFigure 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 sliding groove 611 is formed on the surface of the first mounting seat 61 away from the pulley 2, and the first sliding 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 is slidably engaged with the first sliding groove 611. A first spring 64 is disposed between the two first sliding portions 621, and two ends of the first spring 64 are respectively connected to the two first sliding portions 621. When the first spring 64 is in its original length, the two first sliding portions 621 respectively abut against the two groove end walls of the first sliding groove 611.

[0047] The two half-rings 63 are respectively connected to the two first clamping blocks 62. An arc-shaped cavity 622 is formed in the first clamping block 62, and two ends of the arc-shaped cavity 622 respectively penetrate through two adjacent end faces of the first clamping block 62. The half-ring 63 is 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-ring 63. When the two first clamping blocks 62 approach and abut against each other, the two half-rings 63 abut against each other to form a complete ring, and this complete ring is named a friction ring 67. The half-ring 63 is provided with counterweights 631 at both ends, so that in the natural state, one end of the half-ring 63 is located outside the arc-shaped cavity 622 under the action of gravity, so as to facilitate separating the two first clamping blocks 62.

[0048] Referring to Figure 1 and Figure 4 , the friction plate 4 is fixedly connected to the frame 1, and the friction plate 4 extends along the length direction of the pulley 2. The friction plate 4 is located above the first clamping assembly 6, and the lower surface of the friction plate 4 is for the friction ring 67 to abut against, so that while 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 with the insulating rod, and tightening the handle with the insulating rod.

[0049] In this embodiment, a guiding groove 41 is formed on the surface of the friction plate 4 facing the pulley 2, and the guiding groove 41 extends along the length direction of the pulley 2, and two ends of the guiding groove 41 respectively penetrate through the two end faces of the friction plate 4. The bottom wall of the guiding groove 41 is for the friction ring 67 to abut against, so as to form a certain guiding and limiting effect on the moving path of the friction ring 67 by using the guiding groove 41, and ensure the stability and reliability of the first clamping assembly 6 moving with the pulley 2.

[0050] Among them, both of the two first clamping blocks 62 are electromagnets. When the first clamping assembly 6 moves to face the friction plate 4, the two first clamping blocks 62 are powered on by the power source 85. The opposite surfaces of the two first clamping blocks 62 attract each other, so that the two first clamping blocks 62 approach each other under the action of the attraction force and clamp the insulating rod. After the first clamping assembly 6 leaves the position where the friction plate 4 is located, the first clamping block 62 is disconnected from the power source 85. The two first clamping blocks 62 move away from each other under the elastic force of the first spring 64, and a gap for the insulating rod to escape is formed between the two semi-rings 63, so as to facilitate the escape and blanking of the assembled insulating pull rod. The structure of how the first clamping block 62 is powered on and off as the pulley 2 moves will be further described in detail later.

[0051] Referring to Figure 5 , the second clamping assembly 7 includes a second mounting seat 71 and two second clamping blocks 72. A second sliding groove 711 is formed on the surface of the second mounting seat 71 away from the pulley 2, and the second sliding groove 711 extends along the length direction of the pulley 2. The second clamping block 72 has a second sliding portion 721, and the second sliding portion 721 is slidably engaged with the second sliding groove 711. A second spring 73 is arranged between the two second sliding portions 721. When the second spring 73 is in its original length, the two second sliding portions 721 respectively abut against the two groove end walls of the second sliding groove 711.

[0052] Both of the two 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 both connected to the power source 85. The opposite surfaces of the two second clamping blocks 72 attract each other, so as to clamp the working head and the handle. The structure of how the second clamping block 72 is powered on and off as the pulley 2 moves will be further described in detail later.

[0053] Referring to Figure 1 、 Figure 2 and Figure 6 , the pulley 2 is provided with a plurality of support rods 8. The support rods 8 extend along the length direction of the pulley 2, and the plurality of support rods 8 are arranged at equal intervals along the length direction of the pulley 2. The plurality of support rods 8 correspond to the plurality of clamping mechanisms 3 one by one. The first mounting seat 61 is fixedly connected to the support rod 8.

[0054] An activity 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 an activity block 712 that is slidably engaged with the activity groove 81.

[0055] Referring to Figure 6 and Figure 7, first abutting portions 82 are 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 abutting portion 82. The first elastic member 83 is used to force the second clamping assembly 7 to move towards the first clamping assembly 6. In this embodiment, the first elastic member 83 is a spring. The two ends of the support rod 8 are used as the first abutting portions 82. One end of the first elastic member 83 is connected to the groove end wall of the movable groove 81, and the other end is connected to the second mounting seat 71.

[0056] The following details the specific structure and principle of the power supply 85 being turned on and off during the movement of the first clamping block 62 and the second clamping block 72 along with the pulley 2: Refer to Figure 1 and Figure 8 , there are two guide rails 5. The two guide rails 5 are arranged in a ring shape. The two guide rails 5 are both fixedly connected 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 both sides of the friction plate 4 with respect to the central axis of the friction plate 4. The outer side of the guide rail 5 is for the second mounting seat 71 to abut against. Thus, with the cooperation of the first elastic member 83, the movement path of the second clamping assembly 7 is controlled by the guide rail 5, that is, when the pulley 2 reaches different positions, the distance between the second clamping assembly 7 and the first clamping assembly 6 is different.

[0057] 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, the transition guide portions 52, and the lower guide portion 53 are connected to each other. From one end of the pulley 2 to the other end, the distance between the two upper guide portions 51 first decreases, then remains unchanged, and then increases. The distance between the two transition guide portions 52 is the same, and the distance between the two lower guide portions 53 is the same.

[0058] Refer to Figure 7 , an electrical connection portion 84 is provided at the bottom of the movable groove 81. A power supply 85 is embedded inside the support rod 8. The electrical connection portion 84 is electrically connected to the power supply 85. The electrical connection portion 84 extends along the length direction of the movable groove 81, and the length of the electrical connection portion 84 is less than the distance between the two lower guide portions 53. The second sliding portion is provided with a second conductive portion, and the second conductive portion 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 supply 85.

[0059] When the second clamping assembly 7 moves to the upper guide portion 51, both of the two second clamping assemblies 7 in the same clamping mechanism 3 move towards 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.

[0060] Refer to Figure 3 and Figure 7, a conductive groove 612 is formed on the bottom surface of the first mounting seat 61. The conductive groove 612 extends along the height direction of the first mounting seat 61. A first conductive part 65 is slidably connected in the conductive groove 612 along the height direction of the first mounting seat 61. The first mounting seat 61 is provided with a through port 613. Both ends of the through port 613 penetrate through two side walls of the first mounting seat 61 away from each other. The through port 613 is communicated with the conductive groove 612. There is an insertion gap between the upper end surface of the first conductive part 65 and the bottom wall of the conductive groove 612, and there is a gap between the lower end surface of the first conductive part 65 and the bottom wall of the movable groove 81.

[0061] A second elastic member 66 is arranged in the movable groove 81. The second elastic member 66 is used to push the first conductive part 65 away from the bottom wall of the movable groove 81. In this embodiment, the second elastic member 66 is a spring, and the second elastic member 66 is sleeved outside the first conductive part 65. A second abutting part 651 is integrally formed at the upper end of the first conductive part 65. The second abutting part 651 is used for the upper end of the second elastic member 66 to abut and connect. The other end of the second elastic member 66 is connected to the bottom wall of the movable groove 81.

[0062] Refer to Figure 7 , on one side of the second mounting seat 71 close to the first mounting seat 61, a guide rod 713 is fixedly connected. The end of the guide rod 713 away from the second mounting seat 71 has a guide surface 714. The guide surface 714 is used to abut against the upper end surface of the first conductive part 65. During the process of the second mounting seat 71 approaching the first mounting seat 61, the guide surface 714 is inserted into the insertion gap through the through port 613. Under the action of the guide surface 714, the first conductive part 65 moves towards the direction close to the bottom wall of the movable groove 81 and finally abuts against the bottom wall, so that the first clamping block 62 is connected to the power supply 85. It can be understood that the end of the guide rod 713 away from the second mounting seat 71 should be made of a conductive material, and the part of the first mounting seat 61 between the first clamping block 62 and the first conductive part 65 should also be made of a conductive material.

[0063] Refer to Figure 1 , further, a conveyor belt 9 is arranged below the pulley 2. The conveyor belt 9 is used to transport the work 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.

[0064] It can be understood that in another embodiment, a manipulator can also be arranged on the frame 1 to load the work head, insulating rod and handle, further reducing manual participation.

[0065] The implementation principle of Embodiment 1 is as follows: When assembling the insulating pull rod, the working head, the insulating rod and the handle are conveyed to one end of the pulley 2 by the conveyor belt 9. The staff places the insulating rod on the first clamping assembly 6, and places the working head and the handle on the two second clamping assemblies 7 on both sides of the first clamping assembly 6 respectively. The pulley 2 drives this set of clamping mechanisms 3 to approach the friction plate 4. After this set of clamping mechanisms 3 move to the position of the upper guiding part 51, with the movement of the pulley 2 and the change in the shape of the guiding rail 5, the second clamping assembly 7 moves towards the direction close to the first clamping assembly 6. During the movement, the second clamping block 72 is connected to the power supply 85, the second clamping assembly 7 clamps the working head and the handle, the first clamping block 62 is connected to the power supply 85 under the action of the guiding rod 713, and the second clamping assembly 7 clamps the insulating rod.

[0066] Afterwards, the above-mentioned clamping mechanism 3 reaches below the friction plate 4. During the movement of the pulley 2, it drives the friction ring 67 to move. The friction ring 67 rotates under the cooperation of the friction plate 4, drives the insulating rod to rotate, so that the working head is screwed tightly with the insulating rod, and the handle is screwed tightly with the insulating rod, completing the assembly of the insulating pull rod.

[0067] After the above-mentioned clamping mechanism 3 leaves the upper guiding part 51 and moves to the lower guiding part 53, under the action of the two guiding rails 5, the distance between the two second clamping assemblies 7 reaches the maximum, the second clamping assembly 7 loosens, the friction ring 67 rotates to the end to expose the arc-shaped cavity 622 under the action of the counterweight 631, the two second clamping blocks 72 move away from each other under the action of the second spring 73, the second clamping assembly 7 loosens, and the assembled insulating pull rod falls onto the conveyor belt 9. Afterwards, the above-mentioned clamping mechanism 3 rotates back to the feeding position with the pulley 2, and the above process can be repeated. Embodiment 2

[0068] Refer to 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, and the lifting mechanism 42 is used to control the rising or falling of the friction plate 4.

[0069] Specifically, the first mounting seat 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 pull rods with insulating rods of different thicknesses.

[0070] The above are all the preferred embodiments of this application. The protection scope of this application is not limited by this. Therefore, all equivalent changes made according to the structure, shape and principle of this application should be covered within the protection scope of this application.
