Description

Technical Field

[0001] This utility model relates to the field of tooling technology, specifically to an inverter hoisting tool. Background Technology

[0002] A 10,000-ton battery-grade lithium carbonate project will be constructed on the southeast side of Zabuye Salt Lake, approximately 165 km north of Zhongba County, Shigatse City. The project is about 700 km from Lhasa City, at an altitude of approximately 4,500 meters. Because the lithium carbonate project is located at the end of the power grid, its electricity demand cannot be met, and there are no heat sources nearby. Therefore, the "Tibet Zabuye Integrated Energy Supply Project (hereinafter referred to as the Energy Station)" will be constructed to meet the electricity and steam needs of the lithium carbonate project.

[0003] Zabuye Salt Lake is an inland lake located in southern Tibet. The Zabuye Lake area is a plateau cold and semi-arid climate zone with large annual and daily temperature ranges. The average annual temperature is 1℃, with significant annual and daily temperature variations. The annual precipitation is 192.6 mm, and the annual evaporation is 2269.1 mm. It is frequently windy, with up to 172 windy days per year and an average annual wind speed of 5.8 m / s. The annual sunshine duration is 3300 hours. The lake basin is a closed endorheic basin, replenished by river water, atmospheric precipitation, and groundwater, with atmospheric precipitation being the primary source. It is one of the world's three largest lithium salt lakes.

[0004] When constructing a photovoltaic power station, a medium-voltage grid inverter is required. This outdoor inverter integrates inverter units, transformers, power distribution, and communication equipment. It converts the direct current (DC) from the photovoltaic array into AC power that meets grid connection requirements, allowing direct connection to the medium-voltage grid. This meets the needs of modular design and rapid installation for large and medium-sized photovoltaic power stations. However, the project site is located on a plateau with a complex geographical environment, presenting numerous meteorological and geographical challenges during installation and transportation, making the installation and transportation of the inverter inconvenient.

The terms "vertical", "horizontal", "left", "right", and similar terms as used herein are for purposes of description only.

[0023] Unless otherwise defined, 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 utility model belongs. The terminology used in the description of the utility model herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the utility model. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0024] Referring to Figure 1 and Figure 2 , the utility model provides a kind of inverter hoisting tool, including

[0025] hoist;

[0026] fixed seat, the fixed seat is used to carry inverter body;

[0027] hoisting unit, the hoisting unit includes two first hoisting ropes and two second hoisting ropes, the first hoisting rope passes through one end of the second hoisting rope, the other end of the second hoisting rope is fixedly connected with the fixed seat surface, the middle part of two second hoisting ropes is hung on the hook of the hoist, and the position of the hook makes the fixed seat be in the state of gravity center balance;

[0028] when the hoist moves upward in vertical direction, the fixed seat and the inverter body are in natural horizontal state.

[0029] The first lifting rope is 5 meters long. The second lifting rope is 8 meters long. The load capacity of the first and second lifting ropes is greater than or equal to 9000 kg. The inverter is securely connected to the fixed base via a support member. Several hanging lugs are provided on both sides of the fixed base and on the top of the inverter body; these lugs are used to connect with the lifting unit. The inverter and fixed base are fixedly installed to facilitate handling extreme weather conditions such as strong winds during transport. The fixed base also provides a certain degree of waterproofing, preventing the inverter's base from getting wet. The connection method between the lifting unit and the hooks can maintain the stability of the center of gravity during transport to a certain extent, preventing damage to the inverter during transport and hoisting.

[0030] During use, all components within the inverter are pre-installed and secured at the factory. Transportation involves hoisting the inverter as a whole. The inverter is transported to the power plant site by a freight company, which will notify the site management personnel in advance to arrange delivery and unloading. After delivery, the inverter is moved to its final location, which requires operation by the power plant construction personnel.

[0031] Transporting mobile inverters should at least meet the following conditions:

[0032] All inverter cabinet doors must be locked. During transportation, be sure to use ropes to secure the top lifting rings of the cabinet to the lifting lugs on the inverter base, and then secure the bottom lifting lugs to the transport vehicle to prevent the inverter from tilting at an excessive angle during transportation.

[0033] During the lifting of the inverter, each operation should be carried out according to the following requirements:

[0034] The inverter should be lifted vertically, and it should not be dragged on the ground or the top of the lower cabinet during lifting. The inverter should not be dragged or pushed on any surface.

[0035] When fixing, the inverter is lifted simultaneously from two lifting points at the bottom and the transformer from four lifting points at the top.

[0036] The first suspension rope must first pass through the loop at one end of the second suspension rope, and then the loops at both ends of the first suspension rope are hooked onto the hooks on the same side of the transformer. One loop of the second suspension rope is connected to the bottom flat plate lug, and the other loop is connected to the first suspension rope.

[0037] The crane hook must be connected to the flexible second lifting rope. The overall platform's center of gravity must be kept in balance by adjusting the position of the hook. The inverter can only be lifted after it is balanced. The lifting should be carried out slowly, and the overall balance should be carefully observed. It should not be moved too quickly.

[0038] When positioning the suspension rope, avoid rubbing it against the inverter.

[0039] The inverter should be paused after being moved away from the support surface by 300mm, and the connection between the lifting appliance and the inverter should be checked.

[0040] After the inverter is hoisted and positioned, the lifting ropes need to be adjusted at the free point position to ensure that each lifting rope is uniformly tensioned and the corresponding segment length is consistent, so as to ensure that the whole machine is hoisted stably. After the inverter is in place, it should be gently placed and landed stably, and it is strictly prohibited to place the inverter in a place other than the vertical landing by swinging the lifting appliance.

[0041] The site where the inverter is placed should be solid and flat, with good drainage, no obstacles or protrusions; on the site, the inverter should be supported only by the four bottom corner pieces.

[0042] The specific embodiments of the present application are described above. It should be understood that the present application is not limited to the specific implementation described above, and one or more of the above embodiments can be combined to form a combined embodiment. Those skilled in the art can make various changes or modifications or combinations within the scope of the claims, which does not affect the essential content of the present application. In the case of no conflict, the embodiments of the present application and the features in the embodiments can be combined arbitrarily.
