Description

Technical Field

[0001] The present application relates to the technical field of lightning arrester assembly equipment, and in particular to an insulation assembly station for lightning arresters. Background Art

[0002] A lightning arrester is an electrical appliance used to protect electrical equipment from high transient overvoltage hazards during lightning strikes, and to limit the follow-on time and the follow-on value. There are many types of lightning arresters, among which zinc oxide lightning arresters utilize the good nonlinear volt-ampere characteristics of zinc oxide and have the advantages of superior protection performance, light weight, resistance to dirt, and stable performance. During the production and assembly process of the lightning arrester, the oxide core rod needs to be pressed into the arrester body.

[0003] After searching, the publication number: CN220710046U announced an easy-to-assemble lightning arrester, which adopts the method of coating the upper and lower surfaces of the valve plate to achieve electrical connection of the valve plate parts. At the same time, the coating can make the surface of the valve plate smoother and the force more uniform, preventing the valve plate from being damaged by pressure due to uneven cross-section. No metal conductive sheet is required, so that the lightning arrester only needs to assemble the valve plate when assembling.

[0004] With respect to the above-mentioned related technologies, the inventor believes that there are the following technical defects that need to be improved:

[0005] This device only assists in pressing the arrester assembly by means of a compression spring when assembling the resistor piece, but does not limit the deformation direction of the compression spring, thereby causing the resistor piece of the assembled arrester to be not in close contact, thereby reducing the quality of the finished product. Utility Model Content

[0006] The present application provides a lightning arrester insulation assembly platform to improve the following technical problems:

[0007] When assembling the resistor pieces, the traditional device only uses the compression spring to assist in pressing the arrester assembly, but does not limit the deformation direction of the compression spring, which causes the resistor pieces of the assembled arrester to be not in close contact, thereby reducing the quality of the finished product.

[0008] The present application provides a lightning arrester insulation assembly platform, which adopts the following technical solution:

[0009] A lightning arrester insulation assembly table comprises a flexible adjustable assembly table, wherein the flexible adjustable assembly table comprises a workbench, a movable frame, a display table, an aluminum end cap, a varistor body, a glass fiber strip and a lifting assembly, wherein the movable frame is slidably sleeved on the outer side of the workbench, the display table is fixedly connected to the middle of the top end of the workbench, the lifting assembly is arranged on the top of the movable frame, the aluminum end cap is sleeved on the opposite side of the lifting assembly, the varistor bodies are arranged at equal intervals on the inner side of the aluminum end cap, and the glass fiber strip is sleeved on the outer side of the varistor body.

[0010] In an achievable technical solution of the present application, the lifting assembly includes a hydraulic cylinder, a connecting rod, a support frame and a chuck body, the hydraulic cylinder is threadedly connected to the top of the movable frame, the bottom of the connecting rod is fixedly connected to the surface of the support frame, the outer side of the support frame is plugged into one side of the chuck body, and the inner side of the chuck body is clamped into the inner side of the aluminum end cap.

[0011] In a feasible technical solution of the present application, a notch matching the size of the display table is provided at the bottom of the support frame.

[0012] In an achievable technical solution of the present application, a stepper motor, a bidirectional screw and a linear shaft are also provided inside the workbench. The motor shaft of the stepper motor is fixedly connected to one end of the bidirectional screw through a coupling, the thread surface of the bidirectional screw is screwed to the bottom of the movable frame, and the linear shaft passes through the bottom of the movable frame and is fixedly connected to the inner surface of the workbench.

[0013] In an achievable technical solution of the present application, a thread groove and a through hole matching the sizes of the bidirectional screw and the linear shaft are respectively formed through the bottom of the movable frame.

[0014] In a feasible technical solution of the present application, an arc-shaped groove matching the shape of the glass fiber strip is further provided on the outer side of the aluminum end cap.

[0015] In summary, the present application includes at least one of the following beneficial technical effects:

[0016] 1. When assembling the rheostat body, it can be placed on the display table according to its specific size. Then the staff will insert the aluminum end cap into the inside of the chuck body and stick the spacer to the outside of the aluminum end cap. Then, according to the needs, multiple groups of rheostat bodies can be closely attached to the opposite sides of the two groups of aluminum end caps. Specifically, the stepper motor on the outside of the workbench can be electrically started, and its motor shaft drives the bidirectional screw to rotate. Since the linear shaft runs through the bottom of the mobile frame, it has an obstructive effect on the rotation of the mobile frame. With the cooperation of the thread surface of the bidirectional screw and the built-in thread groove, the two groups of mobile frames can move relative to or away from each other on the inside of the workbench along the opening direction of the through hole, so that the two groups of aluminum end caps on the top are relatively clamped, thereby ensuring the stability of the assembly;

[0017] 2. After the assembly of the varistor body is completed, the staff can hold the fiberglass strip, press its outer side into the arc groove of the aluminum end cap, rotate the chuck body, and put the fiberglass strip in a ring around the outside of the varistor body. Then start the hydraulic cylinder on the top of the mobile frame, and its piston end pulls the bottom connecting rod. The connecting rod drives the support frame and the varistor body to complete the lifting effect, so that the support frame is separated from the display frame along the groove and suspended in the air. The staff can use external equipment to wrap the resin reinforcement rope around the outside of the varistor body and increase its strength. The gap generated during the winding process can allow the sparks and smoke generated by power overload to escape, so that this device can greatly improve the safety of the arrester.

[0033] The lifting assembly 17 includes a hydraulic cylinder 171, a connecting rod 172, a support frame 173 and a chuck body 174. The hydraulic cylinder 171 is threadedly connected to the top of the movable frame 12, the bottom of the connecting rod 172 is fixedly connected to the surface of the support frame 173, the outer side of the support frame 173 is plugged into one side of the chuck body 174, and the inner side of the chuck body 174 is clamped into the inner side of the aluminum end cap 14.

[0034] The bottom of the support frame 173 is provided with a notch 2 that matches the size of the placement table 13 .

[0035] A stepper motor 3, a bidirectional screw 4 and a linear shaft 5 are also provided inside the workbench 11. The motor shaft of the stepper motor 3 is fixedly connected to one end of the bidirectional screw 4 through a coupling. The thread surface of the bidirectional screw 4 is screwed to the bottom of the movable frame 12. The linear shaft 5 passes through the bottom of the movable frame 12 and is fixedly connected to the inner surface of the workbench 11.

[0036] The bottom of the moving frame 12 is penetrated by a thread groove 6 and a through hole 7 which are matched with the sizes of the bidirectional screw 4 and the linear shaft 5 respectively.

[0037] The outer side of the aluminum end cap 14 is also provided with an arc-shaped groove 8 matching the shape of the glass fiber strip 16 .

[0038] The use process of the lightning arrester insulation assembly station of the embodiment of the present application is roughly as follows:

[0039] According to the size of the lightning arrester, a rheostat body 15 of the same model can be placed on the display table 13, the aluminum end cap 14 is inserted along the inside of the chuck body 174, and the spacer is attached to the outside of the aluminum end cap 14.

The staff can use external equipment to wrap the resin reinforcement rope around the outside of the resistor body 15 and increase its strength, and the gap generated during the winding process can allow the sparks and smoke generated by power overload to escape, so that this device can greatly improve the safety of the use of the lightning arrester.
