Description

Technical Field

[0001] This utility model relates to the field of hoisting tools, specifically to an anti-tipping adjustable hoisting tool for the installation of substation equipment. Background Technology

[0002] The anti-tipping adjustable hoisting tool for substation equipment installation is a special tool designed specifically for problems such as tilting and instability that may occur during the hoisting of heavy electrical equipment (such as transformers, circuit breakers, disconnect switches, etc.) in substations. This tool has anti-tipping function and adjustability, which can effectively improve the safety and efficiency of hoisting operations.

[0003] However, substation equipment is usually characterized by its large size, heavy weight, and unstable center of gravity. During hoisting, it is prone to tilting or instability, which may not only damage the equipment but also cause safety accidents. At the same time, the hoisting tools for substation equipment lack sufficient versatility and adjustment flexibility, making it difficult to adapt to the hoisting needs of various equipment.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in related technologies, this utility model proposes an anti-tipping adjustable hoisting tool for substation equipment installation, so as to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows:

[0007] An anti-tipping adjustable hoisting tool for substation equipment installation includes a hoisting frame. An adjustment assembly is located below the hoisting frame. The adjustment assembly includes multiple adjustment slots below the hoisting frame, multiple adjustment seats connected to the inner walls of the adjustment slots, and adjustment frames connected to both ends of the adjustment seats. A rack is located on an opposite side of the adjustment frame, with an adjustment gear meshing with the teeth of the rack. An adjustment rod is located on the adjustment gear, with one end of the adjustment rod connected to one side of the inner wall of the adjustment seat via a bearing, and the other end of the adjustment rod penetrating through the adjustment seat. An auxiliary rod is located on the side of the adjustment frame, with a bearing auxiliary plate connected to one end of the auxiliary rod via a threaded rod.

[0008] Furthermore, in order to better adjust the components for auxiliary limitation and improve stability, an auxiliary component is provided on the adjusting rod and the adjusting seat. The auxiliary component includes a limiting ratchet on the surface of the adjusting rod, a limiting block engaged with the teeth of the limiting ratchet, a limiting post on one side of the limiting block, one end of the limiting post being connected to one side of the adjusting seat, a limiting spring connected to the other side of the limiting block, an auxiliary block on one end of the limiting spring, and the auxiliary block and the limiting block being connected to one side of the adjusting seat through a connecting rod.

[0009] Furthermore, in order to better assist in the protection and adsorption of the installed substation equipment, multiple fixed suction cups are installed on one side of the adjustment frame and adjustment seat.

[0010] Furthermore, in order to better provide auxiliary protection for the installed substation equipment, protective pads are provided on the bearing auxiliary plate, and the protective pads are compatible with the bearing auxiliary plate.

[0011] Furthermore, in order to better adjust and fix the adjustment seats, multiple adjustment seats and the two sides of the lifting frame are provided with equally spaced adjustment holes, and multiple adjustment holes of the lifting frame and the inner wall of the adjustment holes of the adjustment seats are threaded with fixing rods.

[0012] Furthermore, in order to better hoist the installed substation equipment, lifting rings are installed above the hoisting frame and the adjusting frame, and lifting chains are installed on the lifting rings, with one end of the lifting chain connected to a hoisting arm.

[0013] The beneficial effects of this utility model are as follows:

[0014] (1) By setting the adjustment components on the hoisting frame, the relative position between the hoisting frame and the adjustment frame can be precisely adjusted according to the actual size and shape of the substation equipment, so that the hoisting tools can better fit the equipment, provide more stable and uniform support force, effectively prevent the equipment from tilting or becoming unbalanced due to unstable center of gravity during hoisting, realize fine adjustment of the contact area and contact position between the hoisting tools and the equipment, ensure that the hoisting tools and the equipment fit tightly, meet the special hoisting requirements of different equipment, and at the same time, the auxiliary components set on the adjustment components can ensure that the adjustment process is stable and controllable, reduce the impact of external disturbances or slight shaking of the equipment, facilitate the auxiliary limiting device and rapid response adjustment, maintain the dynamic balance of the hoisting system, and further enhance the anti-overturning capability.

[0015] (2) By using the adjustment holes and fixing rods set on the adjustment seat and the hoisting frame, the adjustment seat can be flexibly fixed and disassembled on the hoisting frame. The overall size and shape of the hoisting tool can be quickly adjusted to adapt to substation equipment of different volumes, weights and specifications, which greatly improves the versatility of the tool. At the same time, the protective pads set on the bearing auxiliary plate can effectively reduce the damage such as friction, collision and scratches on the surface of the equipment during hoisting, protect the appearance and integrity of the equipment, and reduce the maintenance costs and quality risks caused by surface damage during the hoisting process. The fixed suction cups set on the adjustment frame and the adjustment seat can further enhance the connection stability between the hoisting tool and the equipment, prevent the equipment from sliding, shaking and other unstable phenomena during hoisting, effectively make up for the shortcomings of the existing hoisting tools in auxiliary protection, and provide a more reliable guarantee for the safe hoisting of the equipment.
