Description

Technical Field

[0001] The utility model relates to the technical field of insulator production, and more specifically, to a firing device for porcelain insulators. Background Art

[0002] An insulator is a special insulating control device that plays an important role in overhead transmission lines. In the early years, insulators were mostly used on telegraph poles. Gradually, many disc-shaped insulators are hung at one end of the high-voltage wire connection tower. It is used to increase the creepage distance and is usually made of glass or ceramic, which is called an insulator. The insulator should not fail due to various mechanical and electrical stresses caused by changes in environmental and electrical load conditions. Otherwise, the insulator will not play a significant role and will damage the service life of the entire line.

[0003] After retrieval, it is found that the publication number is CN213421867U, and the name is a firing device for suspension insulators. This application proposes that during the production process of insulators, a firing device is required to bake the insulators. However, most current firing devices bake the insulators in a vertical position. Since the insulators are in a stationary state in the firing device, the surface is unevenly heated, resulting in inconsistent baking degrees of different parts of the insulators and affecting the overall baking quality. After the first motor starts normally, it causes the two second belt pulleys to drive the lead screw to rotate. Through the lead screw, the rectangular block drives the rectangular rod, the second connecting rod, and the fixing plate to move to the left. The workpiece is clamped and fixed by the two fixing plates. After the second motor starts normally, it causes the two first belt pulleys to drive the round rod and the sprocket to rotate. Through the two sprockets, the sprocket drives the first connecting rod, the second connecting rod, the fixing plate, and the workpiece to rotate slowly. The fixing plate drives the workpiece to rotate slowly. When the workpiece rotates, its outer wall is baked by the baking plate, improving the baking effect of the workpiece, making its outer wall more evenly heated. This device can effectively facilitate the user to bake the insulators. By slowly rotating the insulators, the baking effect of the insulators is improved, making their outer walls more evenly heated, and the baking quality of the insulators is higher. The operation is simpler and more convenient, and it better meets the actual use requirements. However, this application requires multiple motors to meet the function of synchronous firing of multiple porcelain insulators, and its connection and drive form is too complex, making it difficult to stably cope with high-temperature environments, with high production costs. Moreover, its clamping structure works synchronously. When installing insulators, multiple insulators need to be placed between the clamping structures at the same time, and then the motor is started for clamping, which requires multiple people to cooperate synchronously. At the same time, when disassembling the insulators, since the clamping structure releases the clamping synchronously, multiple people need to catch the insulators at the same time, otherwise the insulators will fall and be damaged, resulting in difficult picking and placing of the insulators and affecting the convenience of use. Further improvements can be made.

[0004] In view of the problems in the related art, no effective solution has been proposed yet. Utility Model Content

The inner wall of the resistance furnace 1 is fixedly installed with heating wires 8, and a box door 14 is hinged on the front facade of the resistance furnace 1. When firing porcelain insulators, the magnetic insulators can be placed in the storage basket. Subsequently, the box door 14 is closed, and the heating wires 8 are started to fire the porcelain insulators. During the firing process, the driving motor 10 drives the first shaft rod 2 to rotate, drives the second shaft rod 3 to rotate through the sprockets 11 and the chain 12, and then drives the brackets 4 to rotate.

During the firing process, the driving motor 10 drives the first shaft rod 2 to rotate, drives the second shaft rod 3 to rotate through the sprocket 11 and the chain 12, and then drives the bracket 4 to rotate. The placement basket 5 always remains vertically upward through the rotating pin 9 and rotates synchronously with the rotation of the first shaft rod 2 and the second shaft rod 3, continuously switching the distance between the porcelain insulators and the resistance wire 8 and the firing heating surface, thereby fully improving the uniformity of firing and the working efficiency. At the same time, this device can realize the synchronous firing of a large number of porcelain insulators with a single driving motor 10, the structure is simpler, and the cost is lower. At the same time, the porcelain insulators are placed between the partitions 6 to avoid mutual collision. The staff can directly place the magnetic insulators into the placement basket 5 one by one, and can directly take out the fired magnetic insulators one by one, and the operation is very convenient, significantly improving the convenience of use.
