Technical Field
[0001] The utility model belongs to the technical field of transformer manufacturing auxiliary equipment, and in particular relates to a transformer core protection hanger. Background Art
[0002] Silicon steel sheets are important materials for producing transformers. At present, our company lifts silicon steel sheets through a support with a lifting platform. Since there are no protective measures for the silicon steel sheets placed on the support, they may accidentally slide sideways and fall and injure people during lifting. Silicon steel sheets may also be damaged or deformed during transportation. Utility Model Content
[0003] Design purpose: In order to avoid the shortcomings of the background technology, a transformer core protection hoist is designed that can not only improve the safety of silicon steel sheet lifting, but also has a long service life and can be folded and stored. At the same time, it can prevent the silicon steel sheets from being damaged or deformed during transportation.
[0004] Design plan: To achieve the above design objectives.
[0005] 1. The side guard plate is rectangular, the edge guard plate is an isosceles trapezoid, and the upper base size of the side guard plate is smaller than the lower base size of the side guard plate. The left sides of the two edge guard plates are respectively hinged to the corresponding side of one of the side guard plates through a hinge, and the right sides of the two side guard plates are respectively hinged to the corresponding side of the other side guard plate through a hinge. The outer sides of the two side guard plates are respectively provided with two lug plates, and the upper end faces of the lug plates are provided with through holes that pass through the upper and lower end faces of the lug plates. The design that the inclination angle of the hypotenuse in the edge guard plate matches the inclination angle of the bottom bracket from the hanging to the hook is one of the technical features of the utility model. The purpose of such design is that: the side guard plate is rectangular, the edge guard plate is isosceles trapezoidal and the upper bottom size of the side guard plate is smaller than the lower bottom size of the side guard plate, the left sides of the two edge guard plates are respectively hinged to the corresponding side of one of the side guard plates through a hinge, the right sides of the two side guard plates are respectively hinged to the corresponding side of the other side guard plate through a hinge, the outer sides of the two side guard plates are respectively provided with two lug plates and the upper end faces of the lug plates are provided with through holes penetrating the upper and lower end faces of the lug plates; when in use, after the silicon steel sheet is installed on the bottom bracket, It is only necessary to open the transformer core protection hanger in the retracted state in the length direction, then put it back on the bracket from top to bottom, put on the lifting rope, and then it can be lifted. Due to the protection of the transformer core protection hanger, the silicon steel sheet will not fall and injure people during the lifting process, thereby greatly enhancing the safety of the silicon steel sheet lifting. In addition, the inclination angle of the bevel in the side guard plate matches the inclination angle of the bottom bracket to the hook, preventing the lifting rope from squeezing and deforming the guard plate (side guard plate and / or side guard plate) during lifting, thereby extending the service life of the transformer core protection hanger.
[0006] 2. The side guard plate is composed of two right-angled trapezoidal plates and a hinged part 1, and the right-angled side of one right-angled trapezoidal plate is hinged with the right-angled side of another right-angled trapezoidal plate through a hinged part 1. The purpose of this design is that the side guard plate is composed of two right-angled trapezoidal plates and a hinged part 1, and the right-angled side of one right-angled trapezoidal plate is hinged with the right-angled side of another right-angled trapezoidal plate through a hinged part 1. The arrangement of the hinged part 1 and the hinged part allows the transformer core protection hanger to be folded when not in use, thereby greatly reducing the space required for storing the transformer core protection hanger when it is idle.
[0007] 3. The right-angled trapezoidal plate is composed of an upper cross bar, a lower cross bar, a vertical bar, a diagonal bar and an aluminum plate. The upper cross bar, the lower cross bar, the vertical bar and the diagonal bar are welded to form a right-angled trapezoidal plate frame, and the inner side surface of the right-angled trapezoidal plate frame is riveted with an aluminum plate by rivets; the side guard plate is composed of two cross bars, three vertical bars and an aluminum plate. The two cross bars and the three vertical bars are welded to form a rectangular plate frame, and the inner side surface of the rectangular plate frame is riveted with an aluminum plate by rivets. This design is the third technical feature of the utility model. The purpose of such design is that: the right-angled trapezoidal plate is composed of an upper cross bar, a lower cross bar, a vertical bar, a diagonal bar and an aluminum plate, and the upper cross bar, the lower cross bar, the vertical bar and the diagonal bar are welded to form a right-angled trapezoidal plate frame, and the inner side surface of the right-angled trapezoidal plate frame is riveted with the aluminum plate by rivets; the side guard plate is composed of two cross bars, three vertical bars and an aluminum plate, and the two cross bars and the three vertical bars are welded to form a rectangular plate frame, and the inner side surface of the rectangular plate frame is riveted with the aluminum plate by rivets; due to the low strength of aluminum, it (aluminum plate and aluminum plate 1) is used as an inner plate, so that the silicon steel sheet is not easily damaged or deformed during the lifting process; in addition, due to the light weight of aluminum, it (aluminum plate and aluminum plate 1) is used as an inner plate, which can also reduce the overall weight of the transformer core protection hanger.
[0008] Technical solution: A transformer core protection hanger, comprising two side guard plates and two edge guard plates, the side guard plates are rectangular, the side guard plates are isosceles trapezoidal and the upper base size of the side guard plates is smaller than the lower base size of the side guard plates, the left sides of the two side guard plates are respectively hinged to the corresponding side of one of the side guard plates through a hinge, the right sides of the two side guard plates are respectively hinged to the corresponding side of the other side guard plate through a hinge, the outer side surfaces of the two side guard plates are respectively provided with two lug plates and the upper end surfaces of the lug plates are provided with through holes that pass through the upper and lower end surfaces of the lug plates.
