Description
Technical Field
[0001] This utility model relates to the field of insulating rod testing technology, specifically a continuous insulating rod testing device. Background Technology
[0002] An insulating rod is a tool made of an insulating tube or rod with other functional accessories at its end. Insulating rods are among the most common and numerous safety tools, typically including joint-type, telescopic type, and swing-blade type. With the increasing number of power supply and distribution sites, the quantity and frequency of use of insulating rods are increasing year by year, and the amount of testing required for insulating rods is also growing.
[0003] For many years, there has been a lack of suitable dedicated tools for insulation testing of insulating rods. When testing insulating rods, two corresponding supports, a main support and a secondary support, are typically used. The insulating rods are then arranged at intervals between the two supports, and the ends of adjacent insulating rods are sequentially wrapped with multi-strand wire and connected to the test leads. Finally, a specified high voltage is applied between the test leads at both ends of the insulating rod to conduct the insulation test. The advantages of the currently used testing equipment are its simple structure and low cost. The disadvantage is that for each test, the inspector needs to manually wrap the ends of each insulating rod, which is not only cumbersome and inefficient, but also results in insufficient pre-tightening force of the wire wrapping, increasing the contact resistance between the wire and the insulating rod and failing to effectively test the true insulation performance of the insulating rod. With the increasing number and frequency of insulating rod usage, the number of insulation rod tests is also increasing. Therefore, using the current insulation rod testing equipment will inevitably consume a large amount of manpower and resources. In view of this, this case was developed to address the above problems through in-depth research. Utility Model Content
[0004] To address the shortcomings of existing technologies, this invention provides a continuous insulating rod testing device, which solves the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a continuous insulating rod testing device, comprising a base, on which a main fixed crossarm and a secondary fixed crossarm are symmetrically arranged. A chain conveyor is provided between the main fixed crossarm and the secondary fixed crossarm. An electric lifting assembly is provided at fixed intervals along the chain plate of the chain conveyor. A U-shaped bracket is provided at the moving end of the electric lifting assembly. A main movable crossarm and a secondary movable crossarm are respectively provided above the main fixed crossarm and the secondary fixed crossarm. One end of the main movable crossarm and the secondary movable crossarm is connected to the moving end of a limiting clamping mechanism.

[0006] The aforementioned elastically wrapped conductive component includes a semi-circular polymer conductive sponge block, the semi-circular polymer conductive sponge block being covered with conductive fabric.
[0007] The aforementioned electric lifting assembly includes a box body mounted on the chain plate of the chain conveyor. A battery and a signal processing module are installed inside the box body. An electric push rod is arranged vertically on the top of the box body. A connecting frame is installed at the telescopic end of the electric push rod. Guide and limiting components are installed between the two sides of the connecting frame and the top surface of the box body.
[0008] The aforementioned guide and limit assembly includes a guide sleeve and a guide rod. The guide sleeve is symmetrically arranged on both sides of the electric push rod and located at the top of the box. The guide rod slides through the guide sleeve and its upper end is assembled and fixed to the connecting frame.
[0009] The aforementioned limiting clamping mechanism includes an L-shaped upright frame mounted on a base. A clamping cylinder is provided on the crossbeam of the L-shaped upright frame. The telescopic end of the clamping cylinder is connected to the main movable crossbeam and the auxiliary movable crossbeam respectively through an insulating bracket. Slide grooves are symmetrically arranged on both sides of the L-shaped upright frame. A guide rail is slidably inserted into the slide groove and the guide rail is connected to the side wall of the insulating bracket.
[0010] The aforementioned chain conveyor is equipped with a material receiving trough on the outlet side.
[0011] This invention provides a continuous insulating rod testing device. It offers the following advantages: The continuous insulating rod testing device places a chain conveyor between the main fixed crossarm and the auxiliary fixed crossarm. The chain conveyor is equipped with an electric lifting assembly and a U-shaped bracket to support the insulating rod under test. The operator places the insulating rods to be tested sequentially on the U-shaped bracket, starts the chain conveyor, moves the insulating rods to be tested above the main and auxiliary fixed crossarms, controls the electric lifting assembly to descend, and places the insulating rods to be tested onto the elastically wrapped conductive components on the main and auxiliary fixed crossarms. The device then controls the limit position. The clamping mechanism moves, pushing the secondary fixed crossarm and secondary movable crossarm downwards to fully cover the end of the insulating rod to be tested, and then conducts an electrical test. After the test is completed, the control limit clamping mechanism resets, and the electric lifting component moves upwards to remove the insulating rod from the test position. The chain conveyor continues to move, moving the tested insulating rod out of the current test position, and subsequent insulating rods to be tested enter the test position. The overall device has a compact structure and high reliability. It does not require manual wrapping, which can effectively reduce the labor intensity of the test operation and is conducive to large-scale and continuous testing of insulating rods.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] Example: Refer to the appendix of the instruction manual Figure 1-5 As can be seen, this application specifically designs a continuous insulating rod testing device. A main fixed crossbeam 2 and a secondary fixed crossbeam 3 are symmetrically arranged on a base 1. A chain conveyor 4 is arranged between the main fixed crossbeam 2 and the secondary fixed crossbeam 3. Electric lifting components are arranged at fixed intervals along the chain plate of the chain conveyor 4. A U-shaped bracket 5 is provided at the moving end of the electric lifting component. A main movable crossbeam 6 and a secondary movable crossbeam 7 are respectively arranged above the main fixed crossbeam 2 and the secondary fixed crossbeam 3. One end of the main movable crossbeam 6 and the secondary movable crossbeam 7 is connected to a limiting clamping mechanism. The main fixed crossarm 2, main movable crossarm 6, auxiliary fixed crossarm 3, and auxiliary movable crossarm 7 are each provided with a semi-circular notch. A semi-circular insulating liner 8 is installed inside the semi-circular notch, and an elastically wrapped conductive component 9 is installed inside the semi-circular insulating liner 8. The elastically wrapped conductive component 9 on the main fixed crossarm 2 is connected to the grounding terminal 10 through a wire, and the elastically wrapped conductive component 9 on the auxiliary fixed crossarm 3 is connected to the high-voltage terminal 11 through a wire. In use, the operator places the insulating rod to be tested sequentially on the U-shaped bracket. 5. Start the chain conveyor 4 to move the insulating rod to be tested above the main fixed crossarm 2 and the auxiliary fixed crossarm 3. Control the electric lifting assembly to descend and place the insulating rod to be tested onto the elastic wrapping conductive component 9 on the main fixed crossarm 2 and the auxiliary fixed crossarm 3. Control the limit clamping mechanism to move and push the auxiliary fixed crossarm 3 and the auxiliary movable crossarm 7 downward, thereby fully wrapping the end of the insulating rod to be tested and conducting an electrical test. After the test is completed, control the limit clamping mechanism to reset and the electric lifting assembly to move upward to remove the insulating rod from the test position. The chain conveyor 4 continues to move and moves the tested insulating rod out of the current test position. Subsequent insulating rods to be tested enter the test position. The overall device has a compact structure and high reliability. It does not require manual wrapping, which can effectively reduce the labor intensity of the test operation and is conducive to large-scale and continuous testing of insulating rods. It should be noted that the wiring and pressurization methods of the power frequency withstand voltage test of the insulating rod are existing technologies. Those skilled in the art can use this device according to conventional operating methods, and will not be described in detail here.
[0020] In specific implementation, as a preferred configuration, the aforementioned elastically wrapped conductive component 9 includes a semi-circular polymer conductive sponge block, the semi-circular polymer conductive sponge block being covered with conductive fabric. The elastically wrapped conductive component 9 can automatically wrap the end of the insulating rod, and the wrapping clamping force is reliable, which can ensure the reliability of the wrapping of the insulating rod and help improve the test efficiency and the accuracy of the test conclusions of this insulating rod test device.
[0021] In specific implementation, as a preferred configuration, the aforementioned electric lifting assembly includes a box 12 mounted on the chain plate of the chain conveyor 4. The box 12 contains a battery and a signal processing module. An electric push rod 13 is vertically mounted on the top of the box 12. A connecting frame 14 is mounted on the telescopic end of the electric push rod 13. Guide and limiting components are installed between the two sides of the connecting frame 14 and the top surface of the box 12. The guide and limiting components include a guide sleeve 15 and a guide rod 16. The guide sleeve 15 is symmetrically arranged on both sides of the electric push rod 13 and located at the top of the box 12. The guide rod 16 slides through the guide sleeve 15 and its upper end is fixedly assembled with the connecting frame 14. During use, the electric push rod 13 provides power to adjust the vertical position of the connecting frame 14 and the U-shaped bracket 5, thereby placing the insulating rod into the corresponding elastically wrapped conductive component 9 on the main fixed crossarm 2 and the secondary fixed crossarm 3. After testing, the insulating rod can be removed from the current test position. The structure is compact and highly automated, requiring only periodic replacement of the battery within the corresponding box 12.
[0022] In specific implementation, as a preferred configuration, the aforementioned limiting clamping mechanism includes an L-shaped upright 17 mounted on the base 1. The crossbeam of the L-shaped upright 17 is equipped with a clamping cylinder 18. The telescopic end of the clamping cylinder 18 is connected to the main movable crossarm 6 and the auxiliary movable crossarm 7 respectively through an insulating bracket 19. The L-shaped upright 17 is symmetrically provided with sliding grooves 20 on both sides. A guide rail 21 is slidably inserted into the sliding groove 20. The guide rail 21 is connected to the side wall of the insulating bracket 19. When the chain conveyor 4 cooperates with the electric lifting assembly to place the insulating rod to be tested into position, the telescopic end of the clamping cylinder 18 is controlled to expand, thereby pushing the insulating bracket 19 and the corresponding main movable crossarm 6 and auxiliary movable crossarm 7 downward. Thus, the end of the insulating rod is clamped and fixed by elastically wrapping the conductive component 9. The structure is reliable, highly automated, and does not require manual wrapping.
[0023] In the specific implementation process, as a preferred setting, a material receiving trough 22 is provided on the outlet side of the chain conveyor 4. After the test is completed, as the chain conveyor 4 continues to move, when the insulating rod moves to the position above the material receiving trough 22, the insulating rod will automatically slide into the material receiving trough 22 under the action of gravity, which can further reduce the labor intensity of the test personnel.
[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
