[0025] As can be fully understood by those skilled in the art, the features of different embodiments of the present disclosure may be partially or fully coupled or combined with each other, and may cooperate with each other in various ways and be technically driven. The embodiments of the present disclosure may be executed independently of each other, or may be executed together in a mutually dependent relationship.

[0026] Refer to Figures 1 to 4The utility model discloses a special pickup mechanism for mutual inductors, including a lifting mechanism (not shown in the figure), a frame and a column 1 arranged on the frame, and also including a support shaft 2 and a boom. The lifting mechanism is fixed to the boom by screws. The lifting mechanism mentioned above is a prior art, including a motor, a roller with a steel wire rope and a hook connected to the steel wire rope. The specific structure and relationship are not described in detail. The boom is connected to the support shaft 2 by a rotating connection mechanism and rotates. Therefore, after the hook hangs the mold, the mold is first lifted and suspended in the air, and then the boom rotates by the rotating connection mechanism to lift the mold to another device for final demoulding. The support shaft 2 is connected to the column 1 by a fixed connection mechanism. The setting of the support shaft 2 makes full use of the components of the injection molding machine itself, and the position of the column 1 is also located at the edge of the injection molding machine, so it will not interfere with the large-scale rotation of the boom.

[0027] As shown in the figure, the boom includes a vertical beam 3, a horizontal beam 4 and an oblique beam 5, which are connected by welding to form a triangular frame, and the lifting mechanism is installed on the horizontal beam 4. The vertical beam 3 is fixed to the support shaft 2. The above structure fully guarantees the rigidity of the boom. The vertical beam 3 and the oblique beam 5 are made of square iron pipes, and the horizontal beam 4 is supported by an I-beam. In order to ensure reliability, a rib beam 6 is also included. The rib beam 6 is located in the frame and is fixed to the oblique beam 5 and the horizontal beam 4, so that the rigidity of the entire frame is higher.

[0028] As shown in the figure, the rotating connection mechanism includes a rotating sleeve 7 arranged on the boom, and the support shaft 2 is rotatably matched with the rotating sleeve 7. The support shaft 2 is provided with an upper limit member and a lower limit member for limiting the movement of the rotating sleeve 7 along the support shaft 2. The rotating sleeve 7 consists of two, which are welded to one side of the vertical beam 3 from top to bottom. The boom can rotate around the support shaft 2 through the rotating sleeve 7. Of course, the rotation is carried out by manual push. The above structure is simple and low in cost.

[0029] Specifically, the upper limit member is a top cover 8 fixed to the end face of the support shaft 2, the rotating sleeve 7 can abut against the top cover 8, the top cover 8 is fixed to the end face of the support shaft 2 by screws, and the diameter of the top cover 8 is larger than the diameter of the support shaft 2; the lower limit member includes two half-circle rings 9, an outer ring 10 and a groove 11 arranged on the support shaft 2, the two half-circle rings 9 are clamped in the groove 11, the inner hole of the outer ring 10 is provided with a convex ring 12, the outer ring 10 is sleeved on the support shaft 2, and the half The snap ring 9 is located in the inner hole and is clamped by the outer ring 10, and the convex ring 12 can be clamped with the half snap ring 9 and cannot slide down along the support shaft 2. Because the thickness of the half snap ring 9 is greater than the thickness of the groove 11, when the half snap ring 9 is clamped in the groove 11, part of it will protrude from the groove 11 and just contact with the convex ring 12, thereby supporting the outer ring 10, and the rotating sleeve 7 located below can contact with the outer ring 10, thereby supporting the rotating sleeve 7. The above structure is simple and easy to install, and therefore the cost is also low.

[0030] As shown in the figure, the fixed connection mechanism includes a connecting external thread provided at the end of the column 1 and a nut sleeve 13. A connecting internal thread that mates with the connecting external thread is provided in the inner hole of the nut sleeve 13. The end of the support shaft 2 is located in the nut sleeve 13 and is fixed to the nut sleeve 13 by screws. As a further structure, a nut positioning plate 14 that can abut against the nut sleeve 13 is provided on the column 1, and the nut positioning plate 14 can position the nut sleeve 13 to facilitate installation.

[0031] The above has introduced in detail a special part-taking mechanism for an instrument transformer provided by an embodiment of the present invention. Specific examples are used herein to elaborate on the principle and implementation manner of the present invention. The description of the above embodiments is only used to help understand the method and its core idea of the present invention; at the same time, for those of ordinary skill in the art, according to the idea of the present invention, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation to the present invention.
