Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of switchgear, more particularly to a switchgear plum-pudding contact dismounting device. BACKGROUND

[0002] The connection of the movable and static contacts of the high-voltage switch cabinet in the substation is realized by the plum-pudding contact. The plum-pudding contact is specifically composed of a support and a plurality of groups of contact fingers and springs uniformly distributed in the circumferential direction. The contact fingers are installed on the support and are clamped by the springs to make the plum-pudding contact firmly connected to the movable contact arm. When the plum-pudding contact is overhauled or replaced, it needs to be dismounted from the movable contact arm. If the plum-pudding contact is dismounted by prying open the spring thereon, it is difficult to install and has a certain risk, and the spring will be damaged and deformed, which will cause a safety hazard.

[0003] The prior art disclosed in the utility model with publication number CN213042820U is a high-voltage switch cabinet plum-pudding contact quick dismounting device. The pressure supporting rod drives the sliding block and the unblocking bolt to move forward together, the unblocking block moves axially and expands outward along with the forward movement of the unblocking bolt, the unblocking block contacts the contact fingers of the plum-pudding contact and drives the contact fingers and the spring to expand uniformly to a certain extent, thereby realizing the dismounting of the plum-pudding contact. The dismounting process is simple, time-saving and labor-saving, and can be completed independently by one person. However, the utility model still has the following problems: the staff needs to squeeze the supporting rod to drive the unblocking screw rod to move upward, thereby pushing the unblocking wall to expand outward and unblock the plum-pudding contact. However, the staff needs to continuously squeeze the supporting rod until the plum-pudding contact is taken off and placed in the desired position, and then the supporting rod can be released. If the staff releases the supporting rod halfway, the plum-pudding contact will fall off. Therefore, the utility model proposes a switchgear plum-pudding contact dismounting device.

A fixing shell 11 is fixedly provided on the external threaded post 601 by threaded connection. The fixing shell 11 has an inner hole 111 at its center. A through hole 13 is provided at the center of the external threaded post 601 and the top plate 6. A hollow part 101 communicating with the through hole 13 is provided inside the housing 1. A pressing post is inserted into the hollow part 101. An adjusting post 9 passes through the through hole 13. The lower end of the adjusting post 9 is connected to the... The corresponding extrusion column is fixedly connected by a fixing part. The upper end of the adjusting column 9 passes through the corresponding inner hole 111 and is fixedly connected to the push part 901. The push part 901 is locked in the center of the clamping part, and the lower end of the clamping part is locked in the inner hole 111.

The extrusion column is composed of a fixing column 5 and a rotating column 4. A slider 402 is fixedly provided on both sides of the rotating column 4. Vertical grooves 2 are provided on both sides of the hollow part 101 corresponding to the positions of the sliders 402. A transverse groove 201 is provided on one side of both the upper and lower ends of the vertical groove 2.

[0035] With the above configuration, the extrusion column, adjusting column 9, pushing part 901, and clamping part of this utility model are designed so that when the extrusion column is pushed upward, it drives the adjusting column 9 upward, thereby controlling the pushing part 901 to change the state of the clamping part. This changes the clamping part from being outward at the bottom and inward at the top to being inward at the bottom and outward at the top, thus clamping the plum blossom contact and facilitating its disassembly. The slider 402, vertical slide groove 2, and horizontal slide groove 201 of this utility model are designed so that when the extrusion column moves, the rotating column 4 can be rotated to make the slider 402 lock into the corresponding horizontal slide groove 201 at the top, which can fix the extrusion column. This allows the operator to maintain the outward-facing state of the clamping part without continuous force, continuously clamping the plum blossom contact, facilitating its movement, making it less likely for the plum blossom contact to fall off, and making the disassembly process easier.

The upper end of the rotating column 4 is provided with a rotating groove 401 corresponding to the positions of the connecting column 503 and the spherical part 504. The rotating groove 401 matches the connecting column 503 and the spherical part 504. The fixing part includes a bolt 505. The upper end of the fixed column 5 is provided with a slot 502. The lower end of the adjusting column 9 is locked in the slot 502. The fixed column 5 is provided with side grooves 501 on both sides. Bolt 505 is fixed in the side grooves 501.

Bolt 302 is fixed in the secondary grooves 301. Bolt 302 passes through the corresponding bottom plate 3 and is fixedly connected to the main shell.

[0039] With the above configuration, the connecting column 503 and the spherical part 504 of this utility model ensure that the rotation of the connecting column 503 will not cause the rotation of the fixed column 5; the bolt 505 of this utility model serves to fix the fixed column 5 and the adjusting column 9; the push plate 12 of this utility model facilitates the pusher to push and rotate the rotating column 4; the base plate 3 of this utility model facilitates the removal of the rotating column 4, fixed column 5 and other components on the inner side after the base plate 3 is disassembled, which is convenient for subsequent maintenance and replacement.

[0040] Working principle: the utility model for use, sliding block 402 is set in the lower end horizontal slide groove 201, at this time push part 901 is located in the inner recess groove 701 of the lower end of the clamping plate 7, at this time the clamping plate 7 is with side groove 702 as fulcrum, the lower end moves outward, the upper end moves inward, when needing to clamp plum blossom contact, only need to rotate rotating column 4, make sliding block 402 leave the lower end horizontal slide groove 201 with vertical slide groove 2 corresponding, in the protruding piece 703 of clamping plate 7 is aligned plum blossom contact inner side, push rotating column 4, make rotating column 4 move to the shell 1, at this time fixed column 5 extrude high elastic spring 10 drive adjusting column 9 and move upwards, so that push part 901 moves up, extrude clamping plate 7, make clamping plate 7 with side groove 702 as fulcrum, the lower end moves inward, the upper end moves outward realize the clamping of plum blossom contact inner side, at this time sliding block 402 moves in vertical slide groove 2, when sliding block 402 moves to the upper end horizontal slide groove 201, rotate rotating column 4, make sliding block 402 set in the upper end horizontal slide groove 201, high elastic spring 10 cannot push fixed column 5 back, therefore staff need not continuously push rotating column 4, can make clamping plate 7 clamp plum blossom contact, make plum blossom contact during moving process not because inadvertently loose force and drop, disassembly process is more relaxed.

[0041] The above is only preferred implementation of the utility model, the protection scope of the utility model is not only limited to the above-mentioned embodiment, and all technical solutions under the idea of the utility model belong to the protection scope of the utility model for the technical solutions of the utility model. It should be noted that for ordinary skilled in the art, without departing from the principle of the utility model, a number of improvements and decorations, these improvements and decorations should also be considered as the protection scope of the utility model.
