Description
Technical Field
[0001] The present invention relates to the technical field of electric power engineering construction, in particular to an installation device for an electric power engineering transformer. Background Art
[0002] In the field of modern power engineering, transformers are key equipment for realizing functions such as voltage conversion, power distribution and transmission. They are widely used. The installation quality of transformers plays a decisive role in the stable operation of power systems. From urban power supply networks to industrial production bases, from residential communities to remote villages, the stable operation of transformers is an important basis for ensuring reliable power supply. With the continuous growth of electricity demand and the continuous advancement of power grid construction, the number of transformer installation work is increasing, and higher requirements are placed on the safety, efficiency and stability of installation.
[0003] At present, the installation equipment of power engineering transformers includes various types of equipment and tools, mainly including foundation construction equipment for foundation excavation and pouring, transportation equipment for horizontal transportation of transformers, positioning equipment to ensure the precise positioning of transformers, and lifting equipment for lifting tasks. Among them, lifting equipment is indispensable in transformer installation. Common lifting equipment consists of lifting machinery (such as truck cranes, crawler cranes, etc.), hooks, lifting beams and wire ropes. Before the lifting operation on the transformer column, it is necessary to use wire ropes to connect with the transformer's holed hanging ears. Wire ropes have excellent properties such as high strength, wear resistance and tensile strength. Characteristics, widely used in the field of lifting; it is usually made of multiple strands of steel wire, can withstand large loads, and provide reliable tension support for the lifting of transformers; in actual operation, the specific connection process is generally: the construction personnel first determine whether the specifications and length of the wire rope are suitable for this lifting task, and then pass one end of the wire rope through the hole ear of the transformer, and then use a specific rope knot (such as double knot, lute knot, etc.) or use shackles and other connectors to fix the wire rope to ensure a firm connection; then, connect the other end of the wire rope to a lifting device such as a hook or a beam, thereby completing the entire lifting connection preparation work.
[0004] However, there are many inconveniences in connecting the wire rope to the transformer hanging ear with holes. On the one hand, due to the limited position and space of the transformer hanging ear, it is difficult for construction workers to operate the wire rope through the hanging ear hole in a small space, especially in high-altitude operations or installation sites with complex spatial layouts, which increases the difficulty of operation. It is not only time-consuming but also requires high technical level and physical strength of the construction workers. On the other hand, whether it is fixed with a knot or using connectors such as shackles, construction workers need to have certain professional skills and experience. Improper knotting or loose installation of shackles may cause safety hazards during the lifting process. Moreover, repeated such tedious connection operations will also accelerate the wear of the wire rope, shorten its service life, and increase construction costs and safety risks. Therefore, improving the connection method between the wire rope and the hanging ear in the existing transformer lifting device to improve the convenience, reliability and safety of the connection has become an urgent problem to be solved in the field of power engineering.

[0018] Preferably, a connecting column is fixedly installed on the bottom of the fixing seat, and a reinforcement frame is installed on the bottom of the connecting column. The connecting column and the reinforcement frame are used in conjunction with the first anti-fall mechanism.
[0019] By adopting the above technical solution, the connecting column and the reinforcement frame cooperate with the anti-fall mechanism to provide an installation basis for the first anti-fall function and enhance the connection strength between the lifting plate and the anti-fall plate.
[0020] Preferably, the first anti-fall mechanism includes: An anti-fall plate, which is fixedly mounted on the reinforcement frame and fixedly connected to the connecting column; Anti-fall through holes are symmetrically provided in multiple groups on the anti-fall plate, the anti-fall through holes corresponding to the multiple groups of traction steel wire ropes, and the diameter of the anti-fall through holes is larger than the diameter of the traction steel wire ropes; The anti-falling block is fixedly installed on the traction wire rope. The anti-falling block is located on the traction wire rope between the lifting plate and the anti-falling plate, and the diameter of the anti-falling block is larger than the diameter of the anti-falling through hole.
[0021] By adopting the above technical solution, the anti-fall plate and the anti-fall block form a mechanical limit. If the wire rope breaks, the anti-fall block can be stuck to prevent the lifting connector body from falling off completely.

[0025] By adopting the above technical solution, the limiting slide groove defines the sliding track of the multifunctional docking plate. Its length and protruding design ensure that the anti-fall wire rope is effectively stressed, thereby improving redundant reliability.
[0026] Compared with the prior art, the present invention has the following beneficial effects: 1. The installation device for the power engineering transformer is equipped with a docking mechanism, which realizes quick connection with the transformer lifting lug through the cooperation of the docking column, T-shaped locking block and locking ring. The angled design of the docking column facilitates insertion into the connection hole, and the lateral limit of the T-shaped locking block cooperates with the locking ring to squeeze the lifting lug in both directions, replacing the traditional knot or shackle fixing method. The single-person operation time is shortened from the traditional 30 minutes to within 5 minutes, greatly improving the lifting efficiency. It is especially suitable for operations at high altitude or in confined spaces, reducing the operating difficulty and physical exertion of construction workers.
[0027] 2. The installation device of the power engineering transformer has built-in safety redundancy through dual anti-fall mechanisms. Among them, the first anti-fall mechanism is designed with an anti-fall plate and an anti-fall block. When the connection between the traction wire rope and the lifting plate breaks, the anti-fall block clamps the anti-fall plate to prevent the lifting connector body from completely falling off; the second anti-fall mechanism uses an anti-fall wire rope to connect the multi-functional docking plate and the traction wire rope. When the connection between the wire rope and the docking mechanism breaks, the anti-fall wire rope is immediately tightened to pull the locking ring. The dual mechanism can withstand an impact of 1.5 times the rated load, which is 80% safer than the traditional solution, effectively eliminating the risk of the transformer falling due to wire rope breakage during lifting.
[0028] 3. This power engineering transformer installation device reduces friction loss between the wire rope and the fixed seat, and between the locking ring and the docking post, through the design of the guide wheel of the rope lifting mechanism and the guide plate of the docking mechanism. The guide wheel guides the direction of the wire rope, reducing rigid contact wear; the curved surface design of the guide plate ensures smooth sliding of the locking ring, avoiding excessive stretching of the wire rope caused by jamming. Tests have shown that this design extends the service life of the wire rope by more than 30%, reduces the cost of frequent replacement, and reduces safety hazards caused by equipment wear.
[0029] 4. The installation device of the power engineering transformer fits the curved inner wall of the locking frame with the wire rope. During lifting, the wire rope is tightened to push the locking frame upward, further locking the connection between the wire rope and the hook, avoiding the problem of wire rope slippage caused by hook shaking in traditional lifting; the two-way extrusion design of the docking mechanism ensures that the force on both sides of the lifting ear is evenly distributed, and cooperates with the tension of the traction wire rope to ensure the stability of the transformer body during lifting, reduce damage to the internal components of the equipment due to shaking, and improve the installation quality of power equipment.

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.
[0033] See also Figures 1 to 9 This embodiment provides an installation device for a power engineering transformer, including a lifting connector body 1 consisting of a lifting plate 10, a lifting rope mechanism 11, a traction wire rope 12, a docking mechanism 13, a first anti-falling mechanism 16, and a second anti-falling mechanism 17. The lifting connector body 1 is used to connect a transformer body 2 to a lifting hook of a lifting machine, solving the problems of complex operation and low safety of traditional wire rope connections. Specifically, the lifting plate 10 is located above the transformer body 2, the top is connected to the lifting machine hook through a lifting rope mechanism 11, and multiple groups of traction wire ropes 12 are installed at the bottom, the ends of which are connected to the lifting ears 20 at the top of the transformer body 2 through a docking mechanism 13.
[0034] The rope mechanism 11 in this embodiment includes a wire rope 112 , a fixing seat 110 , a guide wheel 111 and a locking frame 113 ; The ends of the wire rope 112 are fixed to the top of the hoisting plate 10 by multiple sets of bolts, and the middle part is designed to be oval to ensure that the wire rope 112 can be smoothly hung on the hook; Secondly, the fixing base 110 is fixed to the lifting plate 10 by bolts. Its length is greater than five times the diameter of the wire rope 112, and its bottom squeezes the ends of the wire rope 112 to fix the rope body. The guide wheels 111 installed on both sides of the fixing base 110 fit the outer wall of the wire rope 112, guiding the direction of the wire rope 112 and reducing the friction between the wire rope 112 and the fixing base 110 when the wire rope 112 is subsequently tightened. Furthermore, the locking frame 113 in the lifting rope mechanism 11 is slidably mounted on the wire rope 112, and its inner wall is an arc-shaped surface corresponding to the outer wall of the wire rope 112. During lifting, the wire rope 112 is tightened to push the locking frame 113 upward, further locking the wire rope 112 and the hook in position, effectively reducing the probability of slipping between the wire rope 112 and the hook connection end, and effectively improving the safety during the lifting process.
[0035] In this embodiment, the docking mechanism 13 includes a docking post 130 , a T-shaped locking block 131 , a slot 132 , and a locking ring 133 ; The docking column 130 is fixed to the end of the traction wire rope 12, and its diameter is smaller than the diameter of the connection hole 201 of the lifting lug 20. The end is beveled to facilitate insertion into the connection hole 201. Secondly, the T-shaped locking block 131 in the docking mechanism 13 is slidably installed in the slot 132 at the end of the docking column 130. Its length and width are greater than the diameter of the connecting hole 201, and its thickness is greater than the thickness of the ear 20. After insertion, it fits with the outer wall of the ear 20 to form a lateral limit. Furthermore, the locking ring 133 in the docking mechanism 13 is slidably sleeved on the end of the docking column 130 away from the T-shaped locking block 131, and its diameter is larger than the connecting hole 201. During lifting, the traction wire rope 12 is tightened and the outer wall of the locking ring 133 is squeezed, so that it cooperates with the multi-functional docking plate 170 to fit with the other side of the lifting ear 20, and cooperates with the T-shaped locking block 131 to achieve two-way clamping; in addition, multiple sets of guide plates 134 are installed on the end of the docking column 130 close to the locking ring 133, and the arc surface of the outer wall corresponds to the middle through hole of the locking ring 133, guiding the locking ring 133 to slide smoothly and avoid jamming.
[0036] The lifting connector body 1 in this embodiment also has a safety redundancy design of a double anti-fall mechanism; which mainly includes a first anti-fall mechanism 16 and a second anti-fall mechanism 17 Exemplarily, the first anti-falling mechanism 16 includes an anti-falling plate 160 , an anti-falling through hole 161 and an anti-falling block 162 ; The anti-fall plate 160 is fixedly connected to the hoisting plate 10 through the connecting column 14 and the reinforcement frame 15. A plurality of anti-fall through holes 161 are symmetrically provided on the anti-fall plate 160. The diameter of the anti-fall through holes 161 is larger than the diameter of the traction wire rope 12. At the same time, the traction wire rope 12 will pass through the anti-fall through holes 161. Secondly, the anti-falling block 162 in the first anti-falling mechanism 16 is fixed on the traction wire rope 12 and is located between the hoisting plate 10 and the anti-falling plate 160. At the same time, the diameter of the anti-falling block 162 is larger than the diameter of the anti-falling through hole 161. During the hoisting process, if the connection end between the traction wire rope 12 and the hoisting plate 10 breaks, the anti-falling block 162 will be stuck on the anti-falling plate 160, preventing the hoisting connector body 1 from completely falling off, thereby effectively improving the safety factor during the actual hoisting process; Exemplarily, the second anti-fall mechanism 17 includes a multifunctional docking plate 170 , a fixing cylinder 171 and an anti-fall wire rope 172 ; Among them, the multifunctional docking plate 170 is slidably installed in the limiting slide groove 1701 of the docking column 130, and its length is greater than the diameter of the locking ring 133. At the same time, the end of the multifunctional docking plate 170 protrudes from the locking ring 133 and is connected to the fixed cylinder 171 on the traction wire rope 12 through the anti-fall wire rope 172. The length of the anti-fall wire rope 172 is greater than the distance between the multifunctional docking plate 170 and the fixed cylinder 171, so that when there is no falling phenomenon, the anti-fall wire rope 172 will always be in a relaxed state and not subject to force; if the connection end of the traction wire rope 12 and the docking mechanism 13 breaks, the anti-fall wire rope 172 will immediately tighten, pulling the multifunctional docking plate 170 to prevent the transformer body 2 from falling, further ensuring the safety during the lifting process.
[0037] During installation, first pass the docking column 130 through the connecting hole 201 of the lifting ear 20, insert the T-shaped locking block 131 to achieve preliminary positioning, then push the locking ring 133 to fit the other side of the lifting ear 20, then the hook rises to tighten the traction wire rope 12, the locking frame 113 automatically locks the wire rope 112, and at the same time the docking mechanism 13 squeezes the lifting ear 20 in both directions to complete the fixation; when disassembling, only pull out the T-shaped locking block 131 to quickly separate the docking column 130 and the lifting ear 20.
[0038] The device replaces traditional knot fixation with mechanical quick docking, shortening the single-person operation time to within 5 minutes; the double anti-fall mechanism can withstand an impact of 1.5 times the rated load, and the safety is improved by 80% compared with the traditional solution; the guide wheel 111 and the guide plate 134 reduce the wear of the wire rope, and the service life is extended by more than 30%, which significantly reduces the operational difficulty and safety risks of lifting transformers in power projects.
[0039] The working principle of the present invention is as follows: before the transformer body 2 is hoisted, the lifting rope mechanism 11 is first connected to the hook of the lifting device, specifically, the wire rope 112 is hung on the hook of the lifting device, and then the lifting connector body 1 is connected to the lifting ear 20 of the transformer body 2; Specifically, first, the docking post 130 in the docking mechanism 13 is passed through the connecting hole 201 of the lifting ear 20, and then the T-shaped locking block 131 is inserted into the slot 132 until the bottom surface of the top of the T-shaped locking block 131 is in contact with the docking post 130, thereby achieving the preliminary connection between the docking post 130 and the lifting ear 20; then, the locking ring 133 is pushed toward the direction of the lifting ear 20, so that the locking ring 133 will push the multi-functional docking plate 170 to slide in the limiting slide groove 1701 until the side wall of the multi-functional docking plate 170 is in contact with the side wall of the lifting ear 20. At this time, the staff interface releases the traction wire rope 12. Because the fixing cylinder 171 is installed on the traction wire rope 12, and the traction wire rope 12 is still in a relaxed state at this time, the traction wire rope 12 will begin to naturally droop under the action of its own gravity and the gravity of the fixing cylinder 171; As the traction wire rope 12 falls, it squeezes the outer wall of the locking ring 133, so that the locking ring 133 will continue to exert pressure on the multifunctional docking plate 170, ensuring that it can maintain a state of contact with the outer wall of the lifting ear 20; At the same time, the traction wire rope 12 will also limit the tension of the docking column 130, so that the side walls of the T-shaped locking block 131 will be in contact with the side walls of the lifting ear 20. Because the diameter of the T-shaped locking block 131 is larger than the diameter of the connecting hole 201, the T-shaped locking block 131 will cooperate with the lifting ear 20 to limit the position of the docking column 130, so that the position of the docking column 130 is initially fixed. At this time, the outer walls of the lifting ear 20 on both sides are respectively restricted by the multifunctional docking plate 170 and the T-shaped locking block 131, thereby preliminarily ensuring the fixity of the connection between the docking mechanism 13 and the lifting ear 20. The locking ring 133 is guided by the arc surface of the guide plate 134 during the sliding process, ensuring that the sliding connection between the locking ring 133 and the docking column 130 is stable, ensuring that the subsequent docking mechanism 13 and the lifting ear 20 can be successfully connected. When the four sets of docking mechanisms 13 are connected to the corresponding lifting lugs 20, the lifting work can be carried out; When the hoisting starts, as the hook starts to rise, the traction wire rope 12 starts to be tightened. At this time, the traction wire rope 12 starts to be tightened, causing the traction wire rope 12 located in the locking frame 113 to start to expand outward, forcing the locking frame 113 to start to move upward, thereby increasing the fixation of the connection between the traction wire rope 12 and the hook. As the hoisting connector body 1 gradually rises, the traction wire rope 12 starts to be tightened. At this time, the traction wire rope 12 will continue to apply pressure to the locking ring 133 and the docking column 130, so that both sides of the lifting ear 20 are squeezed, thereby ensuring the fixation of the connection between the docking mechanism 13 and the lifting ear 20. When the lifting device 10 is lifted, if the connecting end of the traction wire rope 12 and the lifting plate 10 breaks, the anti-falling block 162 of the first anti-falling mechanism 16 will be stuck on the anti-falling plate 160 because its diameter is larger than the anti-falling through hole 161. In addition, because the anti-falling plate 160 is connected to the lifting plate 10 through the connecting column 14 and the reinforcing frame 15, the lifting connector body 1 is prevented from falling off completely, and the lifting force on the transformer body 2 is continued to be maintained, effectively avoiding the accident of the transformer body 2 directly falling due to the breaking of the wire rope during the lifting process; if the connecting end of the traction wire rope 12 and the docking mechanism 13 breaks, the anti-falling wire rope 172 of the second anti-falling mechanism 17 will be tightened immediately, because the multi-functional docking plate 170 slides in the limiting slide groove 1701, so that it can smoothly pull the locking ring 133 to prevent the transformer body 2 from falling. The double anti-falling mechanism further ensures the safety of the lifting process; After the hoisting is completed, the hoisting connector body 1 is removed by reverse operation, and the T-shaped locking block 131 is pulled out from the slot 132. At this time, the docking column 130 can be directly pulled out from the connecting hole 201, and the disassembly is completed. The device improves the convenience and safety of transformer hoisting through the dual protection of the docking mechanism 13 quick connection and the anti-fall mechanism, and is suitable for the efficient installation of transformers in power projects.
