Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary equipment for transformer core production, and in particular to a transformer core lifting device. Background Technology

[0002] The transformer core weighs approximately 1400 kg. Transporting and lifting it manually is quite laborious, so a lifting device is often needed to lift the transformer core.

[0003] For example, in a lifting device for a transformer core assembly line (patent number CN221420563U), several lifting columns are set on a support panel, and the transformer core is transported to the support panel by a conveyor belt. Then, the lifting columns are used to lift the core to the height of the assembly line. However, since the assembly line procedure is fixed, the core needs to be kept in a specific position for assembly processing. But when the core is transported to the support panel, the position of several cores is not fixed due to the transport angle. When using handling tools such as forks for handling, it is necessary to ensure that different cores are at the same angle position so that the forks can be inserted. Therefore, the existing technology cannot adjust the angle of the lifted core, resulting in certain defects in its use. Utility Model Content

[0004] The purpose of this invention is to provide a transformer core lifting device to solve the problems existing in the prior art. It can effectively adjust the angle of the lifted transformer core, so that the assembly angle of different cores is consistent, thereby improving the subsequent assembly effect.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] Reference Figures 1-4 This utility model provides a transformer core lifting device, comprising:

[0032] The lifting plate 1 is equipped with a lifting mechanism at its bottom to allow the lifting plate 1 to rise and fall vertically.

[0033] Support plate 2 is rotatably connected to the center of the top surface of lifting plate 1 and is used to place the iron core;

[0034] A pair of clamping rods 3 are arranged opposite each other on the top surface of the lifting plate 1 and symmetrically distributed along the center of the support plate 2. A driving assembly is provided inside the lifting plate 1. The driving end of the driving assembly is connected to the pair of clamping rods 3 respectively, so that the pair of clamping rods 3 move closer or further away from each other along the trajectory of the concentric arc outside the support plate 2.

[0035] This invention utilizes a lifting plate 1 and a lifting mechanism to drive the lifting and lowering of a support plate 2. The support plate 2 is rotatably connected to the center of the top surface of the lifting plate 1. A pair of clamping rods 3 are symmetrically slidably connected to the lifting plate 1 along the center of the support plate 2, thus positioning the clamping rods 3 away from the support plate 2. The driving assembly moves the pair of clamping rods 3 closer together to adjust the angle of the iron core placed on the support plate 2. The adjustment stops when the pair of clamping rods 3 clamp the iron core, at which point the iron core is positioned at the center of the pair of clamping rods 3. This allows for the adjustment of the iron core's angle while ensuring that the final angle remains consistent when lifting different iron cores, thereby improving the subsequent assembly effect.

[0036] Furthermore, the driving components include:

[0037] A pair of movable seats 4 are slidably connected to each other on both sides of the lifting plate 1. The top surface of the movable seat 4 is provided with a sliding groove, and a slider 5 is slidably connected in the sliding groove. The two sliders 5 are fixedly connected to a pair of clamping rods 3 in a one-to-one correspondence.

[0038] Among them, the top surface of the lifting plate 1 is provided with several limiting grooves 6 around the outer periphery of the support plate 2. The number of limiting grooves 6 is the same as that of the clamping rods 3 and they correspond one-to-one. The clamping rods 3 are slidably connected in the limiting grooves 6, and the limiting grooves 6 are arc-shaped structures concentric with the support plate 2.

[0039] A driving component is mounted on the lifting plate 1. The driving end of the driving component is connected to a pair of movable seats 4 so that the pair of movable seats 4 can move closer to or further away from each other.

[0040] By opening a limiting groove 6 on the lifting plate 1, the clamping rod 3 is slidably connected in the limiting groove 6. At the same time, the driving component drives a pair of moving seats 4 to move closer or further apart. The slider 5 slides along the slide groove to ensure that the clamping rod 3 slides along the limiting groove 6, thereby moving along the trajectory of the concentric arc outside the support plate 2, and adjusting the angle of the iron core placed on the support plate 2.

[0041] Furthermore, the driving components include:

[0042] The bidirectional lead screw 7 is transferred inside the lifting plate 1. The two ends of the bidirectional lead screw 7 are respectively threaded with connecting blocks 8, and the two connecting blocks 8 are fixedly connected to a pair of movable seats 4 one by one.

[0043] The first stepper motor 9 is fixedly connected to one side of the lifting plate 1, and the output shaft of the first stepper motor 9 is coaxially fixedly connected to the bidirectional lead screw 7.

[0044] The two connecting blocks 8 are moved synchronously by the double-acting screw 7, so that a pair of moving seats 4 slide along the center of the double-acting screw 7. This ensures that while the iron core is clamped by a pair of clamping rods 3, the iron core is turned to adjust the angle, and the angle of the iron core can be perpendicular to the double-acting screw 7.

[0045] Understandably, when placing the iron core, moving the pair of clamping rods 3 to their furthest points allows the iron core to be placed between the pair of clamping rods 3.

[0046] Furthermore, there are two pairs of clamping rods 3, and the two pairs of clamping rods 3 are symmetrically distributed at the four corners of the lifting plate 1 along the center of the support plate 2.

[0047] When two pairs of clamping rods 3 are set and distributed at the four corners of the lifting plate 1, the two pairs are moved to the farthest ends respectively. The two pairs of clamping rods 3 can form a quadrilateral placement area. The iron core only needs to be placed on the support plate 2 and the rotation angle is within the placement area. Under the drive of the two stepper motors 9, the two pairs of clamping rods 3 move closer to each other and rotate the two sides of the iron core. The rotation direction is vertical to the direction of the bidirectional lead screw 7. When clamping the iron core, the stability of the iron core can be further improved.

[0048] Furthermore, the support plate 2 has a cylindrical structure, and a rotating rod 10 is fixedly connected to the center of the bottom surface of the support plate 2. The bottom end of the rotating rod 10 is connected to the lifting plate 1.

[0049] Furthermore, several rubber protrusions 11 are fixed to the top surface of the support plate 2 to increase the contact friction between the iron core and the support plate 2.

[0050] Furthermore, the top edge of clamp 3 has a rounded transition.

[0051] Furthermore, the lifting mechanism is a scissor lift 12.

[0052] Specifically, the top surface of the top plate 124 of the scissor lift 12 is fixedly connected to the bottom surface of the lifting plate 1, the drive block 123 is threaded onto the screw 122, and the second stepper motor 121 drives the screw 122 to rotate, thereby moving the drive block 123 and realizing the lifting of the top plate 124 by the scissor lift frame. This is a conventional technology and will not be described in detail.

[0053] This utility model provides a working principle for a transformer core lifting device:

[0054] The first stepper motor 9 is driven to rotate, causing the connecting blocks 8 at both ends of the double-acting screw 7 to move in a direction away from each other, and driving the moving seat 4 to move. During the movement of the moving seat 4, the clamping rod 3 slides in the limiting groove 6, causing a pair of clamping rods 3 to move in an arc trajectory in a direction away from each other. The two pairs of clamping rods 3 cooperate to form a placement area. The iron core is transported to the support plate 2, and then the two first stepper motors 9 are started. The two pairs of clamping rods 3 move towards each other around the center of the support plate 2. When they contact the side of the iron core, the angle of the iron core is turned until the iron core is clamped. At this time, the angle of the iron core can be ensured to be perpendicular to the double-acting screw 7. At this time, the scissor lift 12 drives the lifting plate 1 to lift the iron core to the assembly line. When the iron core is assembled, the first stepper motor 9 is driven to release the clamping rod 3.
