Description

Technical Field

[0002] Air-core reactors are inductive high-voltage electrical appliances used in power systems to limit short-circuit current, reactive power compensation, and phase shifting. The magnetic flux forms a circuit through the air, so it is called an air-core reactor. Its processing flow is the following stages: plan formulation—drawing design—material procurement—semi-finished product production—finished product assembly—testing—warehousing. Epoxy resin casting windings are carried out during the semi-finished product production stage. When casting epoxy resin, the casting mold is often fixed on a trolley and pushed into a vacuum casting machine for casting and molding.

[0003] After searching, the Chinese patent announcement number CN216957733U discloses a casting device for a dry-type air-core reactor, including a vacuum casting machine and a support seat. The vacuum casting machine is provided with three support seats on the lower surface, and also includes a base. The base is provided on one side of the support seat. The upper surface of the base is groove-shaped and is connected to a support plate through a lifting assembly. Two first slide rails are provided on the upper surface of the support plate, and a trolley is slidably connected to the first slide rail. A mounting plate is provided on the upper surface of the trolley, and a second slide rail is provided on the rear side of the mounting plate. Two sliders are slidably connected to the rear side of the second slide rail.

[0004] However, in actual use, it was found that although the mold on the base plate can be pushed toward the fixed plate for fixation by the two-way hydraulic cylinder, when the mold on the base plate needs to be removed after pouring, the base plate is still stuck in the fixed plate, and the two-way hydraulic cylinder can only be reset, and the base plate cannot be quickly disassembled and lifted, which easily causes a waste of time and affects the subsequent pouring efficiency. Utility Model Content

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0025] Example:

[0026] Reference Figure 1-Figure 5 A casting device for fixing a dry-type air-core reactor comprises a lifting support platform 1, which can be driven by a lifting cylinder or a lifting device, a fixing block 2 is installed on the support platform 1, a detachable placement plate 6 can be placed on the support platform 1, and a casting mold of the dry-type air-core reactor can be placed on the placement plate 6, and a movable groove 201 is also opened on the fixing block 2, a rotating shaft 401 is rotatably installed in the movable groove 201, and a limiting plate 4 is fixedly connected to the rotating shaft 401, and the limiting plate 4 is in a "C" shape. It is provided with upper and lower ends, and the outer wall of the upper end of the limit plate 4 is fixedly connected to the movable groove 201 through a connecting spring 402. An electric push rod 3 is also installed in the middle part of the support platform 1. A push plate 301 is fixedly connected to the output end of the electric push rod 3, and a clamping block 302 is fixedly connected to the push plate 301, and a clamping groove 7 is opened on the placement plate 6. When the electric push rod 3 pushes the clamping block 302 to move, the clamping block 302 will move to the clamping groove 7 on the placement plate 6 to engage with it, so as to fix and limit the placement plate 6.

[0027] At the same time, refer to Figure 4 A groove 202 is provided on the fixed block 2, and then the movable rod 501 is slidably connected to the groove 202. A resist plate 5 is also installed on the movable rod 501 for resisting the outside of the placement plate 6, and a return spring 502 is also sleeved on the movable rod 501, and then the two ends of the return spring 502 are fixedly connected to the resist plate 5 and the groove 202 respectively. Before the placement plate 6 is placed on the supporting platform 1, the limiting plate 4 is limited and contracted by the connecting spring 402, so that the upper end of the limiting plate 4 is resisted against the outer wall of the movable groove 201, and then the upper end of the limiting plate 4 is in a vertical state to avoid interfering with the placement of the placement plate 6, and the lower end of the limiting plate 4 will extend obliquely from the inside of the movable groove 201 to the outside.

[0028] The working principle is as follows: after the placement plate 6 is placed on the supporting platform 1, the switch of the electric push rod 3 is started, so that the electric push rod 3 drives the push plate 301 to move toward the placement plate 6. While moving, the block 302 on the push plate 301 will enter the slot 7 on the placement plate 6 for limiting. At this time, the other side of the placement plate 6 will abut against the lower end of the limiting plate 4, and the upper end of the limiting plate 4 can be rotated while abutting. Moreover, the limiting block 602 is fixedly connected to the top of the placement plate 6. When the lower end of the limiting plate 4 is moved by the thrust, the upper end of the limiting plate 4 will extend to the limiting block 602 for limiting. At this time, the connecting spring 402 is stretched, thereby achieving the effect of limiting and fixing the placement plate 6.

[0029] During this process, the push plate 5 will be compressed, so that the movable rod 501 on the push plate 5 drives the return spring 502 to shrink into the groove 202, thereby realizing convenient limiting of the placement plate 6. When the pouring is completed, the output end of the electric push rod 3 can be driven to return, and the push plate 301 will drive the card block 302 to move out of the card slot 7 of the placement plate 6. At the same time, the movable rod 501 will be expanded by the return spring 502 to drive the push plate 5 to pop out of the groove 202, thereby pushing the placement plate 6. Move, at this time, the upper end of the limit plate 4 will be contracted by the connecting spring 402, and the upper end of the limit plate 4 will be rotated out from the limit block 602, and at the same time, the lower end of the limit plate 4 will gradually reset and move from the movable groove 201, and a hook 601 is also fixedly connected to the top of the placement plate 6, and then the placement plate 6 can be hoisted by the hook 601, which reduces the processing time of the placement plate 6 and enables it to quickly disassemble and hoist the placement plate 6, thereby reducing time waste and improving subsequent casting efficiency.

[0030] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
