Description

Technical Field

[0001] This utility model belongs to the field of insulation wrapping technology, and specifically relates to a stable support for insulation wrapping equipment. Background Technology

[0002] Insulation wrapping equipment, such as large transformer insulation wrapping machines and high-voltage cable insulation layer winding equipment, is a type of power equipment that achieves electrical insulation, mechanical protection, or environmental protection by covering or isolating critical components with insulating materials. This type of equipment is widely used in high-voltage power systems, rail transportation, new energy, and other fields, with its core objectives being to prevent current leakage, reduce electromagnetic interference, and improve safety and reliability.

[0003] Insulation wrapping equipment is typically characterized by its large size, concentrated weight, and offset center of gravity. The equipment itself can weigh several tons to tens of tons, and core working components, such as wrapping rollers and drive mechanisms, are often unevenly distributed, resulting in an uneven load distribution on the supports. Inappropriate support point distribution: some supports, to simplify the structure, adopt a "two-point support" or "single-sided load-bearing" design. Under the eccentric load of large equipment, this can easily generate overturning moments, causing the supports to tilt or shift; long-term load-bearing can also lead to plastic deformation, further deteriorating stability. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a stable support for an insulating wrapping device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a stable support for an insulating wrapping device, including a top plate, wherein there are two top plates, and a bottom plate is provided at the bottom of each of the two top plates. An I-beam is provided between the top plate and the bottom plate, and symmetrical auxiliary support plates are provided between the two top plates. Positioning side plates located at the bottom of the top plate are fixedly installed at both ends of the auxiliary support plates.

[0006] The bottom of the auxiliary support plate is provided with a connecting horizontal plate, and there are symmetrical auxiliary support plates between the connecting horizontal plate and the top plate.

[0007] Preferably, the two ends of the I-beam are screwed to the top plate and the bottom plate respectively, and the two ends of the top plate are provided with symmetrical mounting holes.

[0008] Preferably, the top of the top plate is provided with a bolt that penetrates the top plate to the inner side of the positioning side plate, and the inner sides of both the top plate and the positioning side plate are threadedly connected to each other with the bolt.

[0009] Preferably, a trapezoidal block located inside the top plate is fixedly installed on the top of the positioning side plate, and a trapezoidal groove is provided at the bottom of the top plate for sliding and inserting with the trapezoidal block.

[0010] Preferably, the two ends of the auxiliary support plate are fixedly connected to the auxiliary support plate and the connecting cross plate, respectively.

[0011] Preferably, auxiliary inclined plates are provided on both sides of the auxiliary support plate, and the two ends of the auxiliary inclined plates are fixedly connected to the auxiliary support plate and the connecting cross plate, respectively.

[0012] Preferably, both ends of the connecting horizontal plate are in contact with one side of the I-beam, and the bottom of both ends of the connecting horizontal plate are screwed with a herringbone plate.

[0013] Preferably, the herringbone plate and the I-beam are screwed together, and a reinforcing rib is fixedly installed on the inner side of the herringbone plate, and the reinforcing rib is designed to be inclined.

[0014] In summary, this utility model has the following beneficial effects:

[0015] 1. In actual operation, the trapezoidal block on the top of the auxiliary support plate is smoothly pushed horizontally into the trapezoidal groove at the bottom of the top plate. The inclined surface of the trapezoidal structure has a guiding function. As the pushing process progresses, the contact surface gradually closes from the edge to the whole until the trapezoidal block slides completely into the deepest part of the trapezoidal groove. At this time, through tactile feedback, it can be confirmed that the two have reached the preset ideal fit state, and the bolt holes on the top plate and the positioning side plate are exactly aligned longitudinally, which removes the obstacle of hole position deviation for subsequent fastening operations. The overall process design takes into account both accuracy and convenience.

[0016] 2. During installation, the connecting cross plate and the I-beam are fixed together via a herringbone transition plate: the two flanges of the herringbone plate are tightly fitted to the ends of the connecting cross plate and the web of the I-beam, forming a triangular support structure, which is then secured with multi-point bolts. This combination method utilizes the self-positioning characteristics of the mechanical structure to ensure assembly accuracy, while the rigid connection strengthens the overall load-bearing capacity. The triangular force-bearing design of the herringbone plate further disperses the horizontal load, ensuring that the components of the support are evenly stressed during load-bearing, thus balancing assembly efficiency and structural stability.

[0017] 3. In the use of stable supports, the auxiliary inclined plate and the auxiliary support plate form a triangular stability principle, which transforms the longitudinal vertical pressure borne by the auxiliary support plate into an oblique component force along the extension direction of the inclined plate. This design decomposes the stress originally concentrated at the center of the auxiliary support plate into a multi-directionally dispersed uniform load, which can reduce the local stress peak value of the auxiliary support plate when bearing the wrapped equipment, and significantly improve the structural deformation resistance.

[0018] 4. The reinforcing ribs welded along the axis of the inner side of the I-beam form a 45° angle with the web of the I-beam. The two ends of the ribs are fully welded to the upper and lower flanges of the I-beam, respectively. When the I-beam is subjected to lateral thrust or axial pressure, the reinforcing ribs decompose the concentrated load into an axial component along the direction of the rib and a radial component perpendicular to the web. The axial component is transmitted to the web of the I-beam through the flanges, while the radial component is borne by the welded joint between the reinforcing rib and the web. This disperses the stress that was originally borne by the single web of the I-beam, providing stable support for the wrapping equipment. Attached Figure Description

[0031] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0032] The specific embodiments of this utility model are described below with reference to the accompanying drawings: Example

[0033] refer to Figures 1-5 The stable support of the insulation wrapping equipment includes a top plate 1, and there are two top plates 1. The bottom of each of the two top plates 1 is provided with a bottom plate 101. An I-beam 102 is provided between the top plate 1 and the bottom plate 101. Auxiliary support plates 2 are provided between the two top plates 1. Positioning side plates 201 located at the bottom of the top plate 1 are fixedly installed at both ends of the auxiliary support plates 2.

[0034] The bottom of the auxiliary support plate 2 is provided with a connecting horizontal plate 5, and there are symmetrical auxiliary support plates 4 between the connecting horizontal plate 5 and the top plate 1.

[0035] Specifically, in the use of the stabilizing support, the auxiliary inclined plate 401 and the auxiliary support plate 4 form a triangular stability principle, which transforms the longitudinal vertical pressure borne by the auxiliary support plate 2 into an oblique component force along the extension direction of the inclined plate. This design decomposes the stress originally concentrated at the center of the auxiliary support plate 2 into a multi-directionally dispersed uniform load, which can reduce the local stress peak value experienced by the auxiliary support plate 2 when bearing the wrapped equipment, and significantly improve the structure's resistance to deformation.

[0036] The two ends of the I-beam 102 are screwed to the top plate 1 and the bottom plate 101 respectively. The two ends of the top plate 1 are provided with symmetrical mounting holes 6. The I-beam 102 forms a rigid support frame between the top plate 1 and the bottom plate 101. Through the optimized design of the moment of inertia of the cross section, it can maintain structural stability when subjected to axial pressure and lateral impact force. Even under dynamic load fluctuations, it can still buffer stress through its own deformation to ensure the long-term reliability of the overall support system.

[0037] The top of the top plate 1 is provided with bolts that penetrate from the top plate 1 to the inside of the positioning side plate 201. The inside of both the top plate 1 and the positioning side plate 201 are threadedly connected to each other with bolts. The bolts will be used to install and tighten the top plate 1 and the positioning side plate 201 to ensure the connection stability between the two sides.

[0038] A trapezoidal block 3 located inside the top plate 1 is fixedly installed on the top of the positioning side plate 201. A trapezoidal groove 301 is provided at the bottom of the top plate 1 for sliding and inserting with the trapezoidal block 3. The interlocking of the trapezoidal block 3 and the trapezoidal groove 301 allows the positioning side plate 201 and the top plate 1 to be connected and assembled, thereby enhancing the overall integrity between the two sides.

[0039] The two ends of the auxiliary support plate 4 are fixedly connected to the auxiliary support plate 2 and the connecting horizontal plate 5 respectively. The auxiliary support plate 4 will realize the stability between the auxiliary support plate 2 and the connecting horizontal plate 5 and provide longitudinal support for the pressure of the auxiliary support plate 2.

[0040] Auxiliary inclined plates 401 are provided on both sides of the auxiliary support plate 4. The two ends of the auxiliary inclined plates 401 are fixedly connected to the auxiliary support plate 2 and the connecting horizontal plate 5, respectively. The auxiliary inclined plates 401 and the auxiliary support plate 4 form a triangular stability principle, which transforms the longitudinal vertical pressure borne by the auxiliary support plate 2 into an oblique component force along the extension direction of the inclined plates. This design decomposes the stress originally concentrated at the center of the auxiliary support plate 2 into a multi-directionally dispersed uniform load, which can reduce the local stress peak of the auxiliary support plate 2 and significantly improve the structural deformation resistance.

[0041] Both ends of the connecting horizontal plate 5 are in contact with one side of the I-beam 102. The bottom of both ends of the connecting horizontal plate 5 are screwed with a herringbone plate 501, which will cooperate with the connecting horizontal plate 5 to form a stable connection between the connecting horizontal plate 5 and the I-beam 102.

[0042] The herringbone plate 501 and the I-beam 102 are screwed together. A reinforcing rib 502 is fixedly installed on the inner side of the herringbone plate 501. The reinforcing rib 502 is designed to be inclined. The reinforcing rib 502 welded to the inner side of the herringbone plate 501 along its axis forms a 45° angle with the web of the herringbone plate 501. Its two ends are fully welded to the upper flange and lower flange of the herringbone plate 501, respectively. When the herringbone plate 501 is subjected to lateral thrust or axial pressure, the reinforcing rib 502 decomposes the concentrated load into an axial component along the direction of the rib and a radial component perpendicular to the web. The axial component is transmitted to the web of the I-beam 102 through the flange, while the radial component is borne by the welded joint between the reinforcing rib 502 and the web, so that the stress originally borne by the single web of the herringbone plate 501 is dispersed.

[0043] The working principle of this utility model is as follows: In actual operation, the assembly process of the support needs to be completed first. The overall process design takes into account both precision and convenience. First, the trapezoidal block 3 on the top of the auxiliary support plate 2 is pushed smoothly into the trapezoidal groove 301 at the bottom of the top plate 1 in the horizontal direction. The inclined surface of the trapezoidal structure has a guiding function. As the pushing process progresses, the contact surface gradually closes from the edge to the whole until the trapezoidal block 3 slides completely into the deepest part of the trapezoidal groove 301. Then, the top plate 1 and the positioning side plate 201 are fastened with bolts.

[0044] Meanwhile, the connection between the horizontal plate 5 and the I-beam 102 is achieved through the transition of the herringbone plate 501: the two flanges of the herringbone plate 501 are closely fitted with the ends of the horizontal plate 5 and the web of the I-beam 102 to form a triangular support structure, which is then fixed by multiple bolts.

[0045] The auxiliary inclined plate 401 and the auxiliary support plate 4 form a triangular stability principle, which transforms the longitudinal vertical pressure borne by the auxiliary support plate 2 into an oblique component force along the extension direction of the inclined plate, thereby reducing the local stress peak of the auxiliary support plate 2. When the herringbone plate 501 is subjected to lateral thrust or axial pressure, the stiffener 502 decomposes the concentrated load into an axial component force along the stiffener direction and a radial component force perpendicular to the web. The axial component force is transmitted to the web of the I-beam 102 through the flange, while the radial component force is borne by the welded joint between the stiffener 502 and the web, thus dispersing the stress originally borne by the single web of the herringbone plate 501.

Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.
