Description

Technical Field

[0001] This invention relates to the technical field of hoisting. More specifically, this invention relates to an intelligent hoisting device for transformer cores. Background Technology

[0002] In existing technology, when hoisting a transformer core from a horizontal to a vertical position, four equal-length binding straps are typically first fixed at one end to four rectangularly distributed lifting rings on the core, and the other ends are connected to a hook of a gantry crane. Simultaneously, two annular binding straps are fitted onto the core base and fixed to another hook of the gantry crane. Through the coordinated action of the two hooks, the core is first hoisted horizontally. Then, one hook slowly lowers the annular binding straps, causing one end of the core base to gradually move downwards, thus achieving the flipping of the core towards a vertical position. However, during the initial horizontal hoisting stage, due to the height difference between the four lifting rings in the vertical direction (the upper and lower rows of rings are not on the same horizontal plane), and the upper ends of the four equal-length binding straps being fixed to hooks at the same height, the binding straps connecting to the lower lifting rings remain taut, while the binding straps connecting to the upper lifting rings are slack and cannot effectively participate in bearing the load, thus reducing the stability of the entire hoisting process. Summary of the Invention

[0003] To overcome the shortcomings of existing technologies where the straps connecting the lower lifting ring are always taut while the straps connecting the upper lifting ring are slack and cannot effectively participate in bearing force when horizontally lifting the transformer core, thus reducing the stability of the entire lifting process, this invention provides an intelligent lifting device for transformer cores.

[0004] The technical implementation of the present invention is as follows: a transformer core intelligent hoisting device, comprising a binding strap 1; several binding straps 1 are provided; further comprising binding strap 2, connecting block 1, lock buckle, connecting block 2, round rod 1 and round rod 2; several binding strap 2 are provided on one side of the binding strap; a connecting block 1 is fixedly connected to both ends of each binding strap 2; a lock buckle is installed on each connecting block 1; a connecting block 2 is sleeved on each binding strap 2; a round rod 1 is rotatably connected to each connecting block 2; a round rod 2 is rotatably connected to each connecting block 2.

[0005] Furthermore, it also includes U-shaped rods; a U-shaped rod is fixed to each connecting block 2.

[0006] Furthermore, it also includes rubber sleeves; a rubber sleeve is fitted onto each round rod.

[0007] Furthermore, it also includes auxiliary components, which include steel rings and rubber rings; each round rod 2 is fitted with several steel rings; each round rod 2 is fitted with several rubber rings, with the rubber rings spaced apart from the corresponding steel rings.

[0008] Furthermore, the rubber ring has several grooves.

[0009] Furthermore, it also includes screws; the second connecting block consists of a fixed part and a movable part; the fixed part is inserted into the corresponding movable part; the fixed part is rotatably connected to the corresponding round rod one; the fixed part is fixedly connected to the corresponding U-shaped rod; the movable part is rotatably connected to the corresponding round rod two; and several screws are screwed together between the fixed part and the corresponding movable part.

[0010] Furthermore, it also includes connecting blocks three; each strap two is fixed with two connecting blocks three, and the connecting blocks two are located between the corresponding two connecting blocks three.

[0011] Furthermore, it also includes a buffer assembly, which includes a movable block, a spring, a connecting block four, an arc-shaped rod, and a partition. Each connecting block three is rotatably connected to a movable block. Several springs are fixedly connected to each connecting block three, and the springs are fixedly connected to the corresponding movable blocks. Each connecting block three is fixedly connected to a connecting block four. An arc-shaped rod is slidably connected to each connecting block four in a sealed manner. A partition is fixedly connected to each arc-shaped rod, and the partition slides inside the corresponding connecting block four. A cavity one is formed between each partition and the connecting block four. A cavity two is formed between the lower side of each partition and the corresponding connecting block four. Several micro-holes are opened on each partition, and cavity one communicates with cavity two through the micro-holes.

[0012] Furthermore, the end of the screw is chamfered.

[0013] Furthermore, a sealing ring is provided between the connecting block four and the partition plate.

[0014] The present invention has the following advantages: First, both ends of the second binding strap are fixed to the transformer core. The hook of the gantry crane lifts the second binding strap from the middle through the U-shaped rod. With the cooperation of the second connecting block, the first round rod, and the second round rod, both ends of the second binding strap can be in a taut state. That is, all four lifting parts of the transformer core can be subjected to the lifting tension, which is conducive to improving the lifting stability. At the same time, compared with directly lifting the middle of the second binding strap through the hook, after adding the second connecting block, the first round rod, and the second round rod to the second binding strap, the lifting force point of the second binding strap can be more stably adapted to change. There will be no problem that the second binding strap gets stuck on the hook and cannot move, thus ensuring the stability of the lifting process.

[0015] Second, the rubber sleeve and rubber ring prevent the second binding strap from piling up on one side of the gap between the first and second round rods, thus avoiding any impact on the hoisting operation. At the same time, the steel ring supports the second binding strap, reducing wear on the rubber ring and ensuring service life. Furthermore, by setting the second connecting block as a fixed part and a movable part, when the second binding strap is stuck in the gap between the first and second round rods, the movable part can be removed, the second binding strap can be straightened, and then the movable part can be reinstalled in its original position, making maintenance convenient.

[0016] Third, the connecting block three limits the binding strap two. When one end of the binding strap two falls off, the connecting block three can work with the round rod one and the round rod two to lock the binding strap two, so that the binding strap two can pull the transformer core tight through the other end, preventing it from falling completely to the ground, which helps to improve safety. In addition, when storing the binding strap one and the parts on it, the connecting block three can limit the connecting block two, the round rod one and the round rod two to the middle of the binding strap two. Before the next use, it can prevent the connecting block two, the round rod one and the round rod two from sliding to the end of the binding strap two and requiring manual adjustment of their position.

[0017] Fourth, when one end of the second binding strap falls off from the hoisting part, the fourth connecting block and the partition plate cooperate to move the partition plate inside the fourth connecting block and squeeze the pressure oil during the locking process, thereby effectively buffering the impact force generated by the third connecting block during locking, thus reducing the shaking of the transformer core and improving stability.

Detailed Implementation

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Example 1: A smart lifting device for transformer cores, such as... Figures 1-6 As shown, it includes a binding strap 1; there are two binding straps 1; it also includes a binding strap 2, a connecting block 3, a lock 4, a connecting block 5, a round rod 6, and a round rod 7; two binding straps 2 are provided on the side of the binding strap 1; a connecting block 3 is fixed to both ends of each binding strap 2; a lock 4 is installed on each connecting block 3, and the binding strap 2 is fixed to the hoisting part 81 of the transformer core 8 by the lock 4; a connecting block 5 is sleeved on the outside of each binding strap 2; a round rod 6 is rotatably connected to each connecting block 2; a round rod 7 is rotatably connected to each connecting block 2.

[0029] It also includes a U-shaped rod 201; a U-shaped rod 201 is welded to the upper side of each connecting block 2 5, and the hook of the external crane is hung on the U-shaped rod 201 to carry out hoisting operations on the connecting block 2 5 and its parts.

[0030] First, the transformer core 8 is initially in a horizontal position. At this time, two of the lifting parts 81 are located on the upper side of the transformer core 8, and the other two lifting parts 81 are located on the lower side of the transformer core 8. Four locking buckles 4 are fixed to the four lifting parts 81 of the transformer core 8. The U-shaped rod 201 is fixed to one hook of the gantry crane. Then, two binding straps 1 are attached to the two bases of the transformer core 8 and fixed to the other hook of the gantry crane. Finally, the transformer core 8 is horizontally lifted by the cooperation of the two hooks. During this process, the hook drives the U-shaped rod 201 upward, which in turn drives the connecting block 5, the round rod 6, and the round rod 7 upward. The round rod 7 then drives the middle part of the strap 2 upward. Once the end of the strap 2 connected to the lower lifting part 81 is taut, the hook drives the U-shaped rod 201 to continue moving upward, causing the round rod 6 and the round rod 7 to move on the strap 2 until the end of the strap 2 connected to the upper lifting part 81 is taut. At this point, the round rod 6 and the round rod 7 stop moving on the strap 2, and the hook drives the U-shaped rod 201 to continue moving upward. The movement causes the round rod 27 to pull the binding strap 22 upwards. At this time, both ends of the binding strap 22 are taut, so that the two binding straps 22 simultaneously apply tension to the four lifting parts 81, which, together with the two binding straps 1, lifts the transformer core 8 horizontally. Then, the hook drives the binding strap 1 to slowly descend, so that one end of the base of the transformer core 8 gradually moves down, thereby realizing the flipping of the transformer core 8 to a vertical position. In use, both ends of the binding strap 22 are fixed to the transformer core 8, and the hook of the gantry crane lifts it from the middle of the binding strap 22 through the U-shaped rod 201. With the combined action of connecting block 25, round rod 16, and round rod 27, both ends of the binding strap 22 can be kept taut. This means that all four lifting parts 81 of the transformer core 8 can be subjected to lifting tension, which helps to improve the lifting stability. At the same time, compared with directly lifting the middle of the binding strap 22 by the hook, after adding connecting block 25, round rod 16, and round rod 27 to the binding strap 22, the lifting force point of the binding strap 22 can be more stably adapted to changes. There will be no problem of the binding strap 22 getting stuck on the hook and being unable to move, thus ensuring the stability of the lifting process.

[0031] It also includes a rubber sleeve 202; a rubber sleeve 202 is fitted on the outside of each round rod 6, and the rubber sleeve 202 limits the binding strap 2 through friction.

[0032] If the hoisting operation is improper, the second binding strap 2 may be subjected to force in its width direction (axial direction of the first round rod 6), causing the second binding strap 2 to accumulate on one side of the gap between the first round rod 6 and the second round rod 7. This could lead to the first round rod 6 and the second round rod 7 getting stuck on the second binding strap 2, affecting subsequent hoisting. Therefore, rubber sleeves 202 are installed on the first round rod 6 and the second round rod 7. The rubber sleeves 202 can generate a relatively large static friction force with the second binding strap 2, thereby preventing the second binding strap 2 from accumulating on one side of the gap between the first round rod 6 and the second round rod 7, and thus avoiding affecting the hoisting operation.

[0033] It also includes auxiliary components, which include steel rings 203 and rubber rings 204; six steel rings 203 are fitted on the outer side of each round rod 2 7; five rubber rings 204 are fitted on the outer side of each round rod 2 7, with the rubber rings 204 and the corresponding steel rings 203 spaced apart.

[0034] The rubber ring 204 has several grooves to improve friction.

[0035] During hoisting, part of the weight of the transformer core 8 is applied to the round rod 7 via the second binding strap 2. If a rubber sleeve 202 is fitted on the outside of the round rod 7, the weight will act on the rubber sleeve 202 on the outside of the round rod 7, making the rubber sleeve 202 on the outside of the round rod 7 prone to wear and resulting in a reduced service life. Therefore, several steel rings 203 and rubber rings 204 are fitted in a crisscross pattern on the outside of the round rod 7. During hoisting, the rubber rings 204 can generate a relatively large static friction force with the second binding strap 2, preventing the second binding strap 2 from accumulating on one side of the gap between the round rod 6 and the round rod 7. At the same time, the steel rings 203 support the second binding strap 2, reducing the wear of the second binding strap 2 on the rubber rings 204 and ensuring the service life.

[0036] It also includes screws 205; the connecting block 2 5 is composed of a fixed part 51 and a movable part 52; the fixed part 51 is inserted into the corresponding movable part 52; the fixed part 51 is rotatably connected to the corresponding round rod 6; the fixed part 51 is fixedly connected to the corresponding U-shaped rod 201; the movable part 52 is rotatably connected to the corresponding round rod 7; four screws 205 are screwed together between the fixed part 51 and the corresponding movable part 52, and the fixed part 51 and the movable part 52 are fixed together by the screws 205.

[0037] Under extreme stress, even with the rubber sleeve 202 and rubber ring 204, the second strap 2 may still accumulate and become stuck on one side of the gap between the first rod 6 and the second rod 7. Therefore, the second connecting block 5 is configured as a fixed part 51 and a movable part 52. When the second strap 2 becomes stuck in the gap between the first rod 6 and the second rod 7, a four-corner wrench is used manually to loosen the screw 205, causing the screw 205 to stop fixing the fixed part 51 and the movable part 52 together. Then, the movable part 52 is manually removed, and the movable part 52 drives the second rod 6... 7. Move away from the first round rod 6, then smooth out the second strap 2, then reinsert the movable part 52 into the fixed part 51, and tighten the screw 205 so that the screw 205 fixes the fixed part 51 and the movable part 52 together again, completing the maintenance operation; In use, by setting the second connecting block 2 5 as the fixed part 51 and the movable part 52, when the second strap 2 is stuck in the gap between the first round rod 6 and the second round rod 7, the movable part 52 can be removed, then the second strap 2 can be smoothed out, and then the movable part 52 can be installed back in its original position, making maintenance convenient.

[0038] It also includes a connecting block 3 206; two connecting blocks 3 206 are fixedly attached to each strap 2 2, and the connecting block 2 5 is located between the corresponding two connecting blocks 3 206, and the connecting blocks 3 206 limit the movement of the round rod 1 6 and the round rod 2 7.

[0039] During hoisting, if one end of the second binding strap 2 detaches from the hoisting part 81, the weight of the transformer core 8 will act on the other end of the binding strap 2. Since the binding strap 2 is only fixed to the hook by the connecting block 2 5, the round rod 6, and the round rod 7, the binding strap 2 will move rapidly between the round rod 6 and the round rod 7, potentially causing the transformer core 8 to fall, resulting in low safety. Therefore, a connecting block 3 206 is added to the binding strap 2. When one end of the binding strap 2 detaches from the hoisting part 81, the binding strap 2 moves between the round rod 6 and the round rod 7, causing the connecting block 3 206 to move. When the connecting block 3 206 moves to the gap between the round rod 6 and the round rod 7, the connecting block 3 206 will get stuck in the gap. The second binding strap 2 is locked, while the other end of the second binding strap 2 remains fixed to the transformer core 8, thus preventing the transformer core 8 from falling completely to the ground, which improves safety. During use, the second binding strap 2 is limited by the third connecting block 206. When one end of the second binding strap 2 falls off, the third connecting block 206 can work with the first round rod 6 and the second round rod 7 to lock the second binding strap 2, thereby pulling the transformer core 8 taut through the other end of the second binding strap 2, preventing it from falling completely to the ground, which improves safety. Furthermore, when storing the first binding strap 1 and its parts, the third connecting block 206 can restrict the second connecting block 5, the first round rod 6, and the second round rod 7 to the middle of the second binding strap 2. Before the next use, it can prevent the second connecting block 5, the first round rod 6, and the second round rod 7 from sliding to the end of the second binding strap 2 and requiring manual adjustment of their position.

[0040] Example 2, based on Example 1, such as Figure 4 , Figure 7 and Figure 8 As shown, it also includes a buffer assembly, which includes a movable block 207, a spring 208, a connecting block 209, an arc-shaped rod 2010, and a partition 2011; a movable block 207 is rotatably connected to each connecting block 206; two springs 208 are fixedly connected between each connecting block 206 and its corresponding movable block 207; a connecting block 209 is fixedly connected to each connecting block 206; and an arc-shaped rod 2010 is slidably connected to each connecting block 209 in a sealed manner. 010; Each arc-shaped rod 2010 is fixedly connected to a partition 2011, which slides inside the corresponding connecting block 4 209; A cavity 1 91 is formed between the upper side of each partition 2011 and the corresponding connecting block 4 209; A cavity 2 92 is formed between the lower side of each partition 2011 and the corresponding connecting block 4 209; Several micro-holes 93 are opened on each partition 2011, and the cavity 1 91 is connected to the corresponding cavity 2 92 through the micro-holes 93.

[0041] The end of the screw 205 is chamfered, making it easier to screw the screw 205 into the movable part 52.

[0042] A sealing ring is provided between the connecting block 209 and the partition 2011 to improve the sealing performance.

[0043] During hoisting, if one end of the second binding strap 2 detaches from the hoisting part 81, the second binding strap 2 will move rapidly between the first round rod 6 and the second round rod 7 until the third connecting block 206 impacts the first round rod 6 and the second round rod 7. The impact force is transmitted to the transformer core 8 through the second binding strap 2, causing it to shake and resulting in low stability. Therefore, a buffer component is installed on the third connecting block 206. When detachment occurs, the second binding strap 2 drives the third connecting block 206 and its parts to move, causing the movable block 207 to contact the steel ring 203. The steel ring 203 compresses the movable block 207, causing it to rotate around the third connecting block 206 and compress the spring 208. The movable block 207 then drives the arc-shaped rod. The 2010 moves, and the arc rod 2010 drives the partition 2011 to move inside the connecting block 4 209. The cavity 1 91 and cavity 2 92 are filled with pressurized oil. When the partition 2011 moves inside the connecting block 4 209, the pressurized oil needs to pass through the narrow micro-hole 93, which can reduce kinetic energy and reduce the vibration caused by the impact. In use, when one end of the binding strap 2 2 falls off the hoisting part 81, the connecting block 4 209 and the partition 2011 cooperate to make the partition 2011 move inside the connecting block 4 209 and squeeze the pressurized oil during the locking process, thereby effectively buffering the impact force generated by the connecting block 3 206 when locking, thereby reducing the shaking of the transformer core 8 and improving stability.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the essence and scope of the technical solutions of the present invention.
