Description

Technical Field

[0001] The invention relates to the technical field of ultra-high voltage electricity transmission, and in particular to an automatic feeding device for large sealing rings. Background Art

[0002] In the UHV power transmission industry, all equipment is exposed to the outdoor environment, and the equipment is filled with inert gas to prevent high voltage current from breaking through the protective shell of the equipment. The above characteristics determine that the UHV power transmission equipment has extremely strict requirements for sealing, and the installation of the sealing ring is particularly important. Due to the large size of the sealing ring and the installation process requirements, the traditional sealing ring installation method is manual installation. The consistency of the finished product is difficult to guarantee and the installation efficiency is low, which greatly affects the production of UHV equipment.

[0003] Based on the existing technical deficiencies, the present invention designs a large-scale sealing ring automatic feeding device. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a large-scale automatic feeding device for sealing rings, which has the advantages of automatic feeding and reduced manual intervention.

[0005] The present invention provides the following technical solutions: a large-scale automatic feeding device for sealing rings, comprising a workbench and a conveying platform, wherein two slots for stacking sealing rings are provided inside the workbench, two sealing ring lifting platforms are arranged inside the workbench, and driving structures are arranged on both sides of the inner cavity of the workbench; sealing ring profiling blocks are fixedly installed on both sides of the interior of the conveying platform, suction cups are fixedly installed on one side of the two sealing ring profiling blocks, clamping cylinders are fixedly installed on one side of the two sealing ring profiling blocks, a vacuum generator is fixedly installed on one side of the conveying platform, and a vacuum degree detector is fixedly installed on one side of the outer surface of the workbench.

[0006] As a preferred technical solution of the present invention, the two driving structures include a base plate, and four connecting rods are fixedly installed on the top of the two base plates.

[0007] As a preferred technical solution of the present invention, a servo electric cylinder is fixedly installed on the top of the two base plates, and a connecting plate is hingedly installed on one end of the telescopic rods of the two servo electric cylinders.

[0008] As a preferred technical solution of the present invention, the two connecting plates are fixedly connected to the sealing ring lifting platform, and protective covers are installed on the outside of the two bottom plates.

[0009] As a preferred technical solution of the present invention, two brackets are fixedly installed inside the workbench, and the upper bracket is fixedly connected to the connecting rod by bolts.

[0010] As a preferred technical solution of the present invention, four legs are fixedly installed on the bottom of the outer surface of the workbench, and the four legs are fixedly connected to two brackets.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. This large-scale automatic feeding device for sealing rings uses a conveying platform, a driving structure, and a sealing ring lifting platform. Before work, the sealing rings are manually stacked on the top of the sealing ring lifting platforms on both sides. During work, the conveying platform is driven by a robot to move to the top of the workbench. At this time, the servo electric cylinder is driven to drive the connecting plate to lift the sealing ring lifting platform upward. At this time, the sealing ring is lifted into two sealing ring profiling blocks. At this time, the vacuum generator is started to make the suction cup absorb the lifted sealing ring. Then the robot drives the conveying platform to move to the end cover to be installed. After it is fitted into place with the end cover, the vacuum generator on the gripper is activated first to cut off the vacuum source, and the positive pressure blowing solenoid valve is activated subsequently to blow positive pressure air into the suction cup to ensure that the sealing ring can fall from the suction cup, thereby completing the automatic feeding of the sealing ring.

[0025] Working principle: when a large-scale automatic sealing ring feeding device is used, first of all, before working, the sealing rings are manually stacked on the top of the sealing ring lifting platforms 8 on both sides. During working, the robot drives the conveying platform 2 to move to the top of the workbench 1. At this time, the servo electric cylinder 73 is driven to drive the connecting plate 74 to lift the sealing ring lifting platform 8 upward. At this time, the sealing ring is lifted into the two sealing ring profiling blocks 3. At this time, the vacuum generator 11 is started to make the suction cup 9 absorb the lifted sealing ring. Then the robot drives the conveying platform 2 to move to the end cover to be installed. After it is in place with the end cover, the vacuum generator 11 on the gripper is activated first to cut off the vacuum source, and the positive pressure blowing solenoid valve is activated subsequently to blow positive pressure air into the suction cup 9 to ensure that the sealing ring can fall from the suction cup 9. The automatic feeding of the sealing ring is completed, and subsequent work can be carried out.
