Description

Technical Field

[0001] This utility model belongs to the field of hoisting and lifting technology, and in particular relates to a hoisting device for a high-voltage electrical insulation basin. Background Technology

[0002] The statements in this section are merely background information related to this utility model and do not necessarily constitute prior art.

[0003] When installing high-voltage electrical appliances at heights, the insulating basin is typically lifted using slings from the pre-assembled component side, and its position is adjusted by gravity. However, this method has low installation precision, and significant errors can occur during alignment. Operational errors can cause friction between the contacts and the aluminum casing wall, creating safety hazards. Even minor bumps or protrusions during power-on and power-off can trigger arcing. The insulating basin is usually not a single unit; it is often connected to a conductor at one end. Due to its weight and different assembly scenarios, manual calibration is impossible during static side installation of circuit breakers, leading to poor alignment, displacement, and failure to meet assembly requirements, necessitating readjustment. Using a site crane with slings to hold the flange for installation and connection is also problematic. Maintaining balance during this process is difficult, requiring significant manual support, resulting in low efficiency, a risk of detachment, and a low safety factor.

[0004] Different installation scenarios require different models of high-voltage electrical appliances. Some traditional lifting ring devices may lack unified standards and specifications, leading to differences in size, shape, and load-bearing capacity among lifting rings produced by different manufacturers, causing inconvenience in use and maintenance. Furthermore, some bolts are prone to bending and desiccation during lifting, making disassembly difficult. Utility Model Content

[0005] To address the aforementioned problems and deficiencies in the existing technology, this utility model provides a high-voltage electrical insulation basin hoisting device. The use of lifting rings allows for flexible adaptation to different installation scenarios, and by selecting appropriate lifting tools, separate installation is not required.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A high-voltage electrical insulation basin hoisting device, comprising:

[0008] Connecting ring, first bolt and second bolt;

[0009] The diameter of the first bolt is larger than that of the second bolt; the first bolt and the second bolt are used for positioning and connection with the high-voltage electrical insulation basin.

[0010] In a further technical solution, the first bolt includes a first stud and a first bolt head.

[0011] In a further technical solution, the first stud is connected to the connecting ring via a first bolt head.

[0012] In a further technical solution, the second bolt includes a second stud and a second bolt head.

[0013] In a further technical solution, the second stud is connected to the connecting ring via a second bolt head.

[0014] In a further technical solution, the second stud is an M12 stud, which is used in conjunction with an M12 nut or connector.

[0015] In a further technical solution, the first bolt is fixed at a position 100° to the bolt axis of the second bolt.

[0016] In a further technical solution, the first stud is an M16 stud, which is used in conjunction with an M16 nut or connector.

[0017] In a further technical solution, both the first bolt head and the second bolt head are hexagonal.

[0018] A further technical solution uses CrNiMo special alloy steel as the material.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] The high-voltage electrical insulation basin hoisting device proposed in this utility model can be adapted to multiple scenarios through lifting eye bolts with multiple specifications of threads, greatly reducing the use and replacement of accessories, saving installation time and labor costs, avoiding cumbersome installation steps, and having a more convenient installation method. While facilitating safe installation, it also improves product quality, reduces maintenance difficulties, and shortens maintenance time.

[0021] The hoisting device proposed in this invention offers enhanced stability and is less prone to displacement due to swaying, thus ensuring stable installation. This advantage is particularly pronounced compared to the old method of manually controlling the hoist with slings, as swaying and displacement are significant factors affecting hoisting quality.

[0022] Regarding the installation of the water pressure cover, the hoisting device proposed in this utility model also demonstrates its convenience, reducing the time and effort spent on installation; at the same time, it also reduces the safety risks caused by falling.

[0023] Advantages of the present invention in additional aspects will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0024] The accompanying drawings, which form part of this specification, are used to provide a further understanding of this utility model. The illustrative embodiments of this utility model and their descriptions are used to explain this utility model and do not constitute an improper limitation of this utility model.

[0025] Figure 1 This is a schematic diagram of the structure of a high-voltage electrical insulation basin hoisting device according to the present invention. Detailed Implementation

[0026] It should be noted that the following detailed descriptions are illustrative and intended to provide further explanation of this application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0027] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. It should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0028] To address the issue of frequent replacement of hoisting devices in various scenarios, this utility model discloses a high-voltage electrical insulation basin hoisting device, comprising: a connecting ring 5, a first bolt, and a second bolt;

[0029] The diameter of the first bolt is larger than that of the second bolt; the first bolt and the second bolt are used for positioning and connection with the high-voltage electrical insulation basin.

[0030] The first bolt includes a first stud 1 and a first bolt head 4; the first stud 1 is connected to the connecting ring 5 through the first bolt head 4.

[0031] The second bolt includes a second stud 2 and a second bolt head 3; the second stud 2 is connected to the connecting ring 5 through the second bolt head 3.

[0032] The second bolt is the base part of the eye bolt. The second stud 2 is an M12 stud, which allows it to be directly used with a standard M12 nut or connector, retaining the original function of the eye bolt.

[0033] The first bolt is fixed at 100° to the bolt axis of the second bolt.

[0034] The first bolt is an improved version of the eye bolt, with a new bolt structure of different specifications than the second bolt. The first stud 1 is an M16 stud, which is used with an M16 nut or connector. The thread diameter of the first stud 1 is larger than that of the second stud 2, so that different models of eye bolts can be selected when lifting heavy objects, making the lifting more stable and reliable.

[0035] The overall shape of the eye bolt is an eye structure with two sets of bolt heads and studs; both the first bolt head 4 and the second bolt head 3 are hexagonal for easy tightening with a wrench; the stud part includes a second stud 2 with a standard M12 thread and a first stud 1 with a newly added M16 thread. The transition between the first and second bolts is smooth and robust, ensuring that the eye will not break or deform under stress.

[0036] The high-voltage electrical insulation basin hoisting device proposed in this utility model provides two fixing possibilities by increasing the fixing position of the M16 stud and the lifting eye bolt, making the connection more selective and achieving double fixing.

[0037] By designing the connecting ring portion of the lifting sling, its load-bearing capacity is increased, enabling it to handle heavier lifting tasks. Users can choose to use either the first or second bolt for connection, providing greater installation flexibility and adaptability.

[0038] In this embodiment, a welding process is used to reduce welding internal stress and the amount of base material dissolved into the weld bead, thereby improving the plasticity and toughness of the weld bead and enhancing the overall strength of the lifting ring.

[0039] In this embodiment, the material of the hoisting device is CrNiMo special alloy steel, which has higher strength and hardness than traditional materials.

[0040] In this embodiment, the design shape of the lifting device is based on actual application requirements. Software stress analysis is used to increase the contact area and optimize stress distribution at the ring connections, thereby improving the load-bearing efficiency of the lifting rings. By appropriately increasing the diameter and thickness of the lifting rings, their cross-sectional area and overall strength are increased, thus enhancing the load-bearing capacity.

[0041] This invention has undergone mechanical strength analysis and calculation. Even when a gravity of 9810.000 ul * 4000 mm ul / s^2 is applied to a single bolt, it still maintains a high safety factor.

[0042] Under the condition of satisfying stress, the position of its lifting point is mainly affected by the load due to its small weight. Under the action of gravity, the center of gravity of the lifting point of this utility model is not significantly different from that of the traditional structure.

[0043] The working method of the high-voltage electrical insulation basin hoisting device with multi-specification threads proposed in this utility model is as follows:

[0044] Step S1: Preparation.

[0045] Step S101: Inspect the lifting ring.

[0046] Ensure that the lifting device (lifting ring) is free from cracks, deformation, wear, or other damage; check that the first and second bolt heads of the lifting device are tight to ensure that they will not loosen during use.

[0047] Step S102: Select appropriate slings.

[0048] Select appropriate slings (such as wire ropes, slings, etc.) based on the weight, shape, and size of the object being lifted, ensuring that the load-bearing capacity of the slings meets the weight requirements of the object being lifted.

[0049] Step S103: Determine the hoisting plan.

[0050] Develop a suitable hoisting plan based on the site environment and the characteristics of the object being hoisted; determine the location and number of hoisting points, as well as safety measures during the hoisting process.

[0051] Step S2: Connect.

[0052] Step S201: Connect the high-voltage electrical insulation basin hoisting device and the slings proposed in this utility model. Connect one end of the slings to the connecting ring, ensuring a firm and reliable connection. If using double-ring buckles or butterfly buckles, ensure they are correctly installed and tightened.

[0053] Step S202: Adjust the position of the lifting ring.

[0054] According to the lifting plan, adjust the position and angle of the lifting equipment to align it with the center of gravity of the object being lifted. Ensure that the lifting equipment will not collide with the object being lifted or other objects during the lifting process.

[0055] Step S3: Lifting.

[0056] Step S301: Start the crane.

[0057] Start the crane and slowly lift it to the appropriate height. During the lifting process, carefully observe the condition of the lifting equipment and the load to ensure they remain stable.

[0058] Step S302: Slowly hoist the load.

[0059] Under the control of the crane, the object to be lifted is slowly raised.

[0060] During the hoisting process, be prepared to deal with any abnormal situations that may occur, such as loose hoisting equipment or broken slings.

[0061] Step S303: Positioning and placement.

[0062] Accurately position the object to be hoisted to the target location. During placement, carefully control the descent speed to ensure the object lands smoothly.

[0063] Step S4: Disassembly and inspection.

[0064] After completing the hoisting task, disassemble the hoisting equipment from the machine. Ensure that the hoisting equipment or machine is not damaged during disassembly. The hoisting operation is now complete.

[0065] The hoisting device proposed in this utility model is used to fix the equipment (circuit breaker side, fast grounding side) to the insulating basin in a fixed position. In assembly scenarios with overhead cranes, it eliminates the inconvenience caused by the weight and installation height limitations of manual labor. It is a hoisting device with high overall strength, strong load-bearing capacity, high safety, and convenient installation, which can significantly improve the efficiency of assembly work.

[0066] Although the specific embodiments of the present utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present utility model. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solution of the present utility model are still within the scope of protection of the present utility model.
