Description

Technical Field

[0001] This utility model relates to the field of glazing processing technology for suspension insulators, and in particular to a special bracket tooling for suspension insulators and a glazing circulation conveyor line. Background Technology

[0002] Suspension insulators are generally constructed by gluing insulating components (such as porcelain or glass components) and metal fittings (such as steel feet, iron caps, and flanges) together with adhesive or mechanically clamping them together. Insulators are widely used in power systems and are generally external insulators, operating under atmospheric conditions. Overhead transmission lines, busbars in power plants and substations, and the external energized conductors of various electrical equipment all require insulator support to insulate them from the ground (or grounding objects) or other conductors with a potential difference. After porcelain suspension insulators are fired and molded, a layer of porcelain enamel is applied to their surface to improve their mechanical strength and increase surface smoothness.

[0003] Due to the special structure of suspension insulators, the glazing of their inner eyes, heads, and bodies cannot be completed in one go; these parts need to be glazed separately. In existing technology, the glazing process for the inner eyes and heads requires manual labor or a robotic arm to position the suspension insulator at the processing station. The glazing of the inner eyes and heads is completed at the fixed station, and then the suspension insulator needs to be transferred to other stations manually or by a robotic arm. In this processing method, the transfer and connection of suspension insulators between stations consumes a lot of time; that is, the previous suspension insulator must be unloaded before the next one can be moved to the station for positioning. This results in low production efficiency during mass production. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a special bracket tooling for suspension insulators and a glazing circulation conveyor line to achieve efficient operation of glazing the head and inner eye of suspension insulators and their transfer.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A special bracket fixture for suspension insulators is based on the suspension insulator body, which includes a main body and a head. The main body is shaped like a shelled cylinder, and the head is also shaped like a shelled cylinder. The diameter of the head is smaller than the diameter of the main body. The head and the main body are combined to form a rotating shelled body. The shelled part of the head is an inner eye. The external corners of the main body are chamfered.

[0007] The bracket fixture includes a support plate and a bracket body connected to the upper part of the support plate. The bracket body is provided with an arc-shaped limiting part that matches the chamfered part of the main body of the suspension insulator. The support plate is provided with a clearance hole to avoid the head of the suspension insulator body. In the assembly state, the head of the suspension insulator body is mounted on the arc-shaped limiting part with the head facing down.

[0008] This utility model also relates to a glazing circulation conveyor line, based on the above-mentioned special bracket tooling for suspension insulators; the circulation conveyor line includes an upper conveying mechanism with the conveying direction in the X direction and a lower conveying mechanism with the conveying direction opposite to the X direction, the lower conveying mechanism being located directly below the upper conveying mechanism, and the upper conveying mechanism is specifically a roller conveyor symmetrically distributed on the left and right.

[0009] The circulating conveyor line also includes an ascending conveyor mechanism and a descending conveyor mechanism. The ascending conveyor mechanism is located at the X-direction end of the upper conveyor mechanism, and the descending conveyor mechanism is located at the X-direction end of the lower conveyor mechanism.

[0010] The bracket fixture circulates sequentially between the upper conveying mechanism, the lower conveying mechanism, the lower conveying mechanism, and the rising conveying mechanism;

[0011] The inner eye glazing mechanism is located directly above the middle of the upper conveying mechanism. The inner eye glazing mechanism includes a first lifting cylinder and an inner hole glazing connector connected to the lower end of the first lifting cylinder. The inner hole glazing connector is connected to a glazing suction connector and a glazing flow connector. The glazing suction connector is connected to the glaze pool through a glazing suction pipe, and the glazing flow connector is connected to the glaze pool through a glazing flow pipe. The glazing suction pipe and the glazing flow pipe are respectively connected to a liquid pump.

[0012] The head glazing mechanism is located directly below the inner eye glazing mechanism. The head glazing mechanism includes a second lifting cylinder and a dip platform connected to the upper end of the second lifting cylinder. The dip platform contains glaze liquid.

[0013] Furthermore, in the above-mentioned glazing circulation conveyor structure, the lowering conveyor mechanism includes a third lifting cylinder and a lifting support frame. The lifting support frame is equipped with a conveyor belt that can switch between moving in the X direction or moving away from the X direction. The structures of the rising conveyor mechanism and the lowering conveyor mechanism are the same.

[0014] Furthermore, in the above-mentioned glazing circulation conveyor line structure, the dip platform is cylindrical in shape, and the diameter of the dip platform is smaller than the clearance hole.

[0015] Furthermore, in the above-mentioned glazing circulation conveyor structure, the dead corner of the support plate is provided with a guide wheel with the axial direction in the vertical direction, the upper conveying mechanism is provided with a side plate, and the guide wheel and the side plate roll together as the bracket fixture moves along the upper conveying mechanism in the X direction.

[0016] The beneficial effects of this utility model are as follows: by designing a bracket fixture specifically for glazing the head and inner eye of suspension insulators, and designing a circulating conveyor line and a head glazing mechanism and an inner eye glazing mechanism set at specific positions, the bracket fixture can circulate on the circulating conveyor line. The suspension insulators only need to be loaded and unloaded on the bracket fixture at the beginning and end of the upper conveyor mechanism by a robot. Compared with the method of loading and unloading directly at the glazing station, the production efficiency is greatly improved in mass production. Attached Figure Description

[0030] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0031] Please refer to Figures 1 to 6The specific embodiment of this utility model relates to a special bracket tool 1 for suspension insulators, based on a suspension insulator body 2. The suspension insulator body 2 includes a main body 22 and a head 21. The main body 22 is shaped like a shelled cylinder, and the head is shaped like a shelled cylinder. The diameter of the head is smaller than the diameter of the main body 22. The head and the main body 22 are combined to form a shelled rotating body. The shelled part of the head is an inner eye. The external corner of the main body 22 is provided with a chamfer 23.

[0032] The bracket fixture 1 includes a support plate 11 and a bracket body 12 connected to the upper part of the support plate 11. The bracket body 12 is provided with an arc-shaped limiting part 121 that matches the chamfer 23 of the main body 22 of the suspension insulator body 2. The support plate 11 is provided with a clearance hole to avoid the head of the suspension insulator body 2. In the assembly state, the head of the suspension insulator body 2 is mounted on the arc-shaped limiting part 121 with the head facing down.

[0033] The specific embodiments of this utility model also involve a glazing circulation conveyor line 3, based on the above-mentioned special bracket tooling 1 for suspension insulators; the circulation conveyor line 3 includes an upper conveying mechanism 31 with a conveying direction of X and a lower conveying mechanism 32 with a conveying direction opposite to X, the lower conveying mechanism 32 is located directly below the upper conveying mechanism 31, and the upper conveying mechanism 31 is specifically a roller conveyor symmetrically distributed on the left and right.

[0034] The circulating conveyor line 3 also includes an ascending conveyor mechanism 33 and a descending conveyor mechanism 34. The ascending conveyor mechanism 33 is located at the X-direction end of the upper conveyor mechanism 31, and the descending conveyor mechanism 34 is located at the X-direction end of the lower conveyor mechanism 32.

[0035] The bracket fixture 1 circulates sequentially between the upper conveying mechanism 31, the lowering conveying mechanism 34, the lower conveying mechanism 32, and the rising conveying mechanism 33;

[0036] The inner eye glazing mechanism 4 is located directly above the middle of the upper conveying mechanism 31. The inner eye glazing mechanism 4 includes a first lifting cylinder 41 and an inner hole glazing connector 42 connected to the lower end of the first lifting cylinder 41. The inner hole glazing connector 42 is connected to a glazing suction connector and a glazing flow connector. The glazing suction connector is connected to the glaze pool through a glazing suction pipe, and the glazing flow connector is connected to the glaze pool through a glazing flow pipe. The glazing suction pipe and the glazing flow pipe are respectively connected to a liquid pump.

[0037] The head glazing mechanism 5 is located directly below the inner eye glazing mechanism 4. The head glazing mechanism 5 includes a second lifting cylinder 51 and a dip platform 52 connected to the upper end of the second lifting cylinder 51. The dip platform 52 contains glaze liquid.

[0038] When the bracket fixture 1 moves in conjunction with the suspension insulator body 2 to directly below the inner eye glazing mechanism 4 and directly above the head glazing mechanism 5, the corresponding bracket fixture 1 is blocked by the blocking component, preventing it from moving in the X direction with the upper conveying mechanism 31. The first lifting cylinder 41 is controlled to drive the inner hole glazing connector 42 to extend into the inner eye of the suspension insulator body 2, and glaze liquid is introduced into the inner eye through the glaze flow head. After a period of time, the excess glaze liquid in the inner eye is removed through the glaze suction connector. The second lifting cylinder 51 is controlled to drive the dip platform 52 to rise, so that the head of the suspension insulator body 2 is immersed in the dip platform 52. After a period of time, the first lifting cylinder 41 is controlled to move upward and the second lifting cylinder 51 is controlled to move downward, so that the inner hole glazing connector 42 is disengaged from the inner eye and the dip platform 52 is disengaged from the head. At this time, the blocking component is controlled to release the limit on the bracket fixture 1, and the upper conveying mechanism 31 continues to drive the bracket fixture 1 to move in the X direction.

[0039] In a preferred embodiment, the lowering conveyor 34 includes a third lifting cylinder 341 and a lifting support frame 342. The lifting support frame 342 is provided with a conveyor belt 343 that can switch between moving in the X direction or moving away from the X direction. The structures of the rising conveyor 33 and the lowering conveyor 34 are the same.

[0040] When the upper conveying mechanism 31 delivers the suspension insulator body 2, which has completed the head and inner eye glazing operations, to the end of the upper conveying mechanism 31 in conjunction with the bracket fixture 1, the conveyor belt 343 of the lowering conveying mechanism 34 is aligned with the upper conveying mechanism 31. The movement direction of the conveyor belt 343 is controlled to be X-axis, so that the corresponding bracket fixture 1 is transferred to the lifting support frame 342. The suspension insulator body 2 on the bracket fixture 1 is transferred by the robot arm, and the third lifting cylinder 341 of the lowering conveying mechanism 34 drives the lifting support frame 342 to move to its conveyor belt 34. At a position flush with the lower conveyor mechanism 32, the moving direction of the control conveyor belt 343 is switched to the opposite direction of X, so that the corresponding bracket fixture 1 is transferred to the lower conveyor mechanism 32. When the lower conveyor mechanism 32 transports the bracket fixture 1 to the opposite end of X, the bracket fixture 1 is transferred to the beginning of the upper conveyor mechanism 31 by the rising conveyor mechanism 33 (the structural principle is the same as the falling conveyor mechanism 34). Before being sent into the upper conveyor mechanism 31, the blank of the next suspension insulator body 2 that needs to be glazed is loaded onto the corresponding bracket fixture 1 by the robotic arm.

[0041] In a preferred embodiment, the immersion platform 52 is cylindrical in shape, and its diameter is smaller than that of the clearance hole. This allows the head of the suspension insulator body 2 to be immersed in the immersion platform 52 through the clearance hole, thus achieving glazing of the head.

[0042] In a preferred embodiment, the support plate 11 is provided with a guide wheel in the vertical direction at the dead corner, and the upper conveying mechanism 31 is provided with a side plate. During the movement of the bracket fixture 1 along the upper conveying mechanism 31 in the X direction, the guide wheel and the side plate roll together.

[0043] In the above embodiments, the design of the guide wheel and side plate enables the bracket tool 1 to be laterally sliding and limited when it moves, thereby improving the stability of the conveying.

[0044] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent modifications made based on the content of this utility model specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of this utility model.
