Description

Technical Field

[0001] The utility model belongs to the field of GIS manufacturing, and in particular relates to a moving contact centering device. Background Art

[0002] GIS products are widely used in electrical system construction.

[0003] The working principle of GIS is to set a static end and a dynamic end, and make the dynamic end electrically coupled with the static end through physical movement. Specifically, linear telescopic movement is a common application of physical movement. A dynamic end connecting conductor is set at the dynamic end, and a dynamic contact is set in the dynamic end connecting conductor in a telescopic manner. In order to make the layout of the accessories in the GIS more compact, the extension axis of the dynamic end connecting conductor is inclined relative to the dynamic end reference installation surface, that is, Figure 1 shown.

[0004] Although this arrangement is compact in layout, in the process of verifying the assembly coaxiality between the moving end connecting conductor and the moving contact, the moving end reference installation surface is used as the detection reference surface, so the detection of the moving end connecting conductor is relatively complicated.

[0010] Preferably, the centering base plate has a centering rail portion extending along its own extending direction, and the end clamping plate has a second guide shoe matched with the centering rail portion.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. Because the movable contact centering device of the utility model includes a base frame, a lifting frame and two end clamp assemblies, the lifting frame is movably arranged on the base frame in the vertical direction, the lifting frame is provided with a centering base plate which is extended obliquely, the two end clamp assemblies are arranged on the centering base plate along the extension direction of the centering base plate, the end clamp assembly includes an end clamp cylinder and an end clamp plate, the two end clamp plates respectively have a conductor plug-in through hole and a contact plug-in through hole, the conductor plug-in through hole matches the movable end connection conductor, the contact plug-in through hole matches the movable contact, the conductor plug-in through hole and the contact plug-in through hole are coaxial and the axis is parallel to the axis of the movable end connection conductor, when verifying the assembly coaxiality of the movable end connection conductor and the movable contact When the movable end connecting conductor is placed directly below the utility model, the lifting frame is driven to move downward until the two end clamps are respectively located on the two outer sides of the movable end connecting conductor in the extension direction, and are coaxially corresponding to the movable end connecting conductor and the movable contact, and then the movable contact is driven to extend out of the movable end connecting conductor. Finally, the two end clamps are driven to move toward the movable contact and the movable end connecting conductor respectively. If the conductor plug-in through hole matches the movable end connecting conductor, and the contact plug-in through hole matches the movable contact, the movable end connecting conductor and the movable contact must be coaxial. Otherwise, the movable end connecting conductor and the movable contact are not coaxial. Therefore, the utility model can quickly verify the assembly coaxiality of the movable end connecting conductor and the movable contact. BRIEF DESCRIPTION OF THE DRAWINGS

It should be noted that the description of these implementation methods is used to help understand the present invention, but does not constitute a limitation of the present invention.

[0017] like Figure 2 As shown, the moving contact centering device 100 in this embodiment is used to verify the coaxiality between the moving contact and the moving end connecting conductor.

[0018] Specifically, Figure 1 As shown, the moving contact and the moving end connecting conductor are both cylindrical, the moving contact can be telescopically inserted into the inside of the moving end connecting conductor, and the moving end connecting conductor is installed on the moving end reference mounting surface of the moving end coupling end plate through a connecting rod, the moving end coupling end plate is flat, the moving end reference mounting surface is a plane, and the axis of the moving end connecting conductor is inclined relative to the moving end reference mounting surface. In this embodiment, the coaxiality of the moving contact and the moving end connecting conductor is verified by horizontally setting the moving end coupling end plate on the moving carrier.

[0019] The moving contact centering device 100 includes a base frame 10 , a lifting frame 20 , a lifting electric cylinder 30 and an end clamp assembly 40 .

[0020] The base frame 10 has two vertically extending lifting columns 11 . The lifting columns 11 have vertically extending lifting guide rails 111 . In the present embodiment, the base frame 10 further has a fixed bottom plate 12 . The base frame 10 is horizontally arranged via the fixed bottom plate 12 .

[0021] The lifting frame 20 is movably disposed on the base frame 10 in a vertical direction, and the lifting frame 20 has a first guide shoe 211 and a centering base plate 23 .

[0022] Specifically, the lifting frame 20 also has a movable fixed plate 21 and an intermediate bracket 22, the first guide shoe is formed on the movable fixed plate 21, and the movable fixed plate 21 cooperates with the lifting guide rail portion 111 through the first guide shoe 211, and the centering base plate 23 is fixed on the movable fixed plate 21 through the intermediate bracket 22, and the centering base plate 23 is arranged to extend obliquely relative to the horizontal plane.

[0023] The centering substrate 23 has a centering rail portion 231 extending along its own extending direction. Specifically, the centering rail portion 231 is located on a surface away from the intermediate bracket 22 .

[0024] The lifting cylinder 30 is arranged between the two lifting columns 11 and the output shaft of the lifting cylinder 30 extends vertically. The lifting frame 20 is fixed on the output shaft of the lifting cylinder 30 through the movable fixing plate 21. Specifically, the lifting cylinder 30 is located below the lifting frame 20, and the upper end of the centering base plate 23 is farther away from the lifting column 11 than the lower end. In this embodiment, the lifting cylinder 30 is fixed to the side of the lifting column 11 through a bracket.

[0025] There are two end clamp assemblies 40 , and the two end clamp assemblies 40 are arranged on the centering substrate 23 along the extension direction of the centering substrate 23 .

[0026] The end clamp assembly 40 includes an end clamp cylinder (not shown in the drawings) and an end clamp plate 41 disposed at the output end of the end clamp cylinder.

[0027] The driving direction of the end clamp cylinder is parallel to the axis of the movable end connecting conductor, and the end clamp plate 41 has a second guide shoe (not shown in the drawings) that cooperates with the centering guide rail portion 23a.

[0028] The two end clamps 41 respectively have a contact plug-in hole 41a and a conductor plug-in hole 41b. The conductor plug-in hole 41b matches the movable end connecting conductor, and the contact plug-in hole 41a matches the movable contact. The conductor plug-in hole 41b and the contact plug-in hole 41a are coaxial and the axis is parallel to the axis of the movable end connecting conductor.

[0029] The following describes the use of the moving contact centering device 100 in conjunction with the embodiments:

[0031] Next, the lifting frame 20 is driven downward by the lifting electric cylinder 30 until the two end clamping plates 41 are respectively located on the two outer sides of the moving end connecting conductor in the extension direction, and the two end clamping plates 41 are coaxially corresponding to the moving end connecting conductor and the moving contact.

[0032] Finally, the moving contact is extended out of the moving end connecting conductor, and the two end clamps 41 are driven to move toward the moving contact and the moving end connecting conductor respectively. If the conductor plug-in hole 41b cooperates with the moving end connecting conductor socket, and the contact plug-in hole 41a cooperates with the moving contact socket, the coaxiality of the moving end connecting conductor and the moving contact must be qualified. Otherwise, the coaxiality of the moving end connecting conductor and the moving contact is unqualified.
