Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of transformer transportation, and specifically to a safe transportation device for large transformers. Background Art
[0002] Oil-immersed transformers are a type of commonly used large transformers, which are mainly electrical devices that use the principle of electromagnetic induction to achieve the conversion of electrical energy voltage levels. Such transformers include a tank shell welded by steel plates, with windings and iron cores installed inside the tank shell. The tank shell is filled with transformer oil for insulation and heat dissipation. One end of the top of the tank shell is equipped with an oil conservator for adjusting the amount of transformer oil, and multiple high- and low-voltage outlet terminals are also installed on the top of the tank shell; The transformer transportation process mainly includes three processes: hoisting the transformer onto the transport vehicle, transporting the transformer to the destination by the transport vehicle, and hoisting and unloading the transformer from the transport vehicle. When hoisting the transformer, the current transportation device is not easy to adjust the center of gravity of the transformer. For example, the weight of the oil conservator is concentrated at one end of the transformer, which will cause the transformer to be in an uneven stress state during hoisting and is prone to the risk of tilting and falling. During the process of transporting the transformer to the destination, the transport vehicle sometimes encounters a sloping road surface, and the traditional transformer fixed on the transport vehicle will be tilted on the vehicle. The tilted transportation of the transformer will cause the oil level of the transformer oil to move and flow out, thereby damaging the windings or other sensitive components. Moreover, the tilted transportation of the transformer will also cause the windings to be subjected to uneven stress, which is likely to cause the windings to be deformed and damaged due to accelerated deformation. Summary of the Invention
[0003] The purpose of the present invention is to provide a safe transportation device for large transformers to solve the problems raised in the above background art.
[0004] To achieve the above purpose, the present invention provides the following technical solutions: A safe transportation device for large transformers, comprising: A support part, fixed on the top of the tail plate of the peripheral transport vehicle. The support part includes two support seats, and an arc-shaped plate one is fixed between the two support seats; A moving part, arranged on the top of the support part. The moving part includes a carrier plate for carrying the transformer. Cross beams are fixed at both ends of the carrier plate, and the cross beams are in rolling connection with the arc-shaped plate one. A braking component is arranged in the middle of the carrier plate; A protective cover, sleeved outside the transformer. A center-of-gravity adjusting part is arranged on the inner top of the protective cover. Multiple positioning columns are fixed on the bottom surface of the protective cover. The center-of-gravity adjusting part includes a hydraulic cylinder two fixedly installed with the protective cover, and an arc-shaped clamping plate capable of driving the oil conservator to move is fixed at the output end of the hydraulic cylinder two; Multiple fixing components, respectively arranged at the positions among the cross beam, the positioning column, and the U-shaped base at the bottom of the transformer, for fixing the transformer, the moving part, and the protective cover together; There are two ropes, which are inserted between the U-shaped base and the protective cover and are used for hoisting the transformer.
[0005] Furthermore: Two rollers are rotatably arranged at the bottom of the cross beam, and two arc tracks for the rollers to roll are fixed on the top surface of the first arc plate.
[0006] Furthermore: The fixing assembly includes: A U-shaped clamping plate is inserted between the carrier plate and the U-shaped base, and the U-shaped clamping plate is fixedly installed on the carrier plate by screwing with bolts; A screw rod is screwed and fixed among the U-shaped base, the positioning column and the cross beam.
[0007] Furthermore: The braking assembly includes a first hydraulic cylinder fixedly embedded in the carrier plate, and a friction plate is detachably fixed at the output end of the first hydraulic cylinder.
[0008] Furthermore: A second arc plate is fixed on the top surface of the first arc plate, the output end of the first hydraulic cylinder penetrates through the second arc plate, the friction plate is arc-shaped, and the friction plate, the first arc plate and the second arc plate are all concentric.
[0009] Furthermore: A support plate is fixed at one end inside the protective cover, and two connecting columns are fixed at the top of the protective cover.
[0010] Furthermore: A V-shaped frame is rotatably installed on the outer side of the connecting column, and both ends of the V-shaped frame are fixedly installed on the corresponding support seats by bolts.
[0011] Furthermore: The center of gravity adjusting member further includes: A transmission column is fixed at the output end of the second hydraulic cylinder, and the bottom end of the transmission column is fixed to the U-shaped clamping plate; A baffle is fixed at one end of the U-shaped clamping plate and is used to push the high-voltage and low-voltage outgoing terminals.
[0012] Furthermore: Two traction ropes are fixed between the baffle and the protective cover, and the middle parts of the traction ropes are fixed to the high-voltage and low-voltage outgoing terminals at the corresponding positions.
[0013] Furthermore: A plurality of shaft rods are detachably screwed and inserted between the two ends of the protective cover, and two adjacent shaft rods are symmetrically distributed on both sides of the high-voltage and low-voltage outgoing terminals.
[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. By sleeving and fixing the protective cover on the outside of the transformer, the protective cover can block rainwater and dust, playing a role in protecting the transformer during the transportation process. After the protective cover is sleeved onto the top of the transformer, the arc-shaped clamping plate inside the protective cover clamps on the outside of the oil conservator. Multiple shaft rods are pre-inserted inside the protective cover, and two adjacent shaft rods are clamped and limited on both sides of the high- and low-voltage outgoing terminals. The bolts that fix the oil conservator and the high- and low-voltage outgoing terminals to the transformer are disassembled and detached from the transformer. The output end of the second hydraulic cylinder contracts, causing the arc-shaped clamping plate to drive the oil conservator to move towards the middle position at the top of the transformer. The baffle on the arc-shaped clamping plate also pushes the high- and low-voltage outgoing terminals close to the oil conservator towards the middle position of the transformer, effectively preventing the oil conservator from being at one end of the transformer and causing the transformer to tilt during hoisting, which is beneficial to improving the safety and stability of the transformer hoisting.
[0015] 2. By fixing an arc-shaped plate 1 on the tail plate of the transport vehicle, a carrier plate is rotatably connected to the arc-shaped plate 1. After the transformer and the protective cover are integrally hoisted onto the carrier plate, the transformer and the protective cover as a whole are fixed to the carrier plate using a fixing component. When the transport vehicle moves to an uphill or downhill section, the inclination of the vehicle tail plate will cause the arc-shaped plate 2 to tilt. At this time, the carrier plate rolls on the arc-shaped plate 1 under the action of the vertically downward gravity of the transformer through the rollers, enabling the transformer to always be in a vertical arrangement state, effectively preventing the transformer from being tilted on the transport vehicle due to the inclination of the transport vehicle when going uphill or downhill, which may lead to the loss or leakage of the transformer oil inside the transformer tank shell, and is beneficial to ensuring that the transformer windings and other sensitive components can always be in an oil-immersed state, achieving the effect of protecting the transformer.
[0016] 3. By arranging the transformer in a rotatable connection manner on the arc-shaped plate 1 through the carrier plate, when the tail plate of the transport vehicle is tilted, the self-gravity of the transformer is used to drive the carrier plate to automatically rotate and adjust to a balanced state on the inclined arc-shaped plate 1, enabling the transformer to always be vertically placed on the carrier plate, and the center of gravity of the winding can be stably supported on the transformer, effectively preventing the stress distribution inside the winding from changing and preventing the phenomenon of winding deformation and damage. After the carrier plate drives the transformer to adjust to the optimal balanced position, the output end of the first hydraulic cylinder drives the friction plate to move upward and abut against the bottom surface of the arc-shaped plate 2, which can limit and fix the carrier plate after the position adjustment, so that the carrier plate can stably support and fix the transformer.

Specific embodiments
[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0020] Example 1, please refer to Figure 1 - Figure 8, in the embodiments of the present invention, a safety transportation device for a large transformer includes a support part 100 fixed to the rear plate of an external transportation vehicle. The support part 100 includes two support seats 110. An arc-shaped plate 120 is fixed between the two support seats 110. A moving part 200 is arranged at the top of the support part 100. The moving part 200 includes a carrier plate 210 for carrying the transformer. Cross beams 220 are fixed at both ends of the carrier plate 210. The cross beams 220 are in rolling connection with the arc-shaped plate 120. A braking component 230 is arranged in the middle of the carrier plate 210. A protective cover 300 is detachably installed and fixed above the carrier plate 210. The protective cover 300 is used to protect the transformer. A center of gravity adjusting part 310 is arranged at the inner top of the protective cover 300. A plurality of positioning columns 320 are fixed to the bottom surface of the protective cover 300. The center of gravity adjusting part 310 includes a hydraulic cylinder 311 fixedly installed with the protective cover 300. An arc-shaped clamping plate 313 capable of driving the oil conservator 720 to move is fixed to the output end of the hydraulic cylinder 311. Fixing components 400 are arranged between both ends of the cross beam 220 and the corresponding positioning columns 320. The fixing components 400 are used to fix the transformer, the moving part 200, and the protective cover 300 together. Two ropes 500 for hoisting the transformer and the protective cover 300 as a whole are inserted and connected between the U-shaped base 710 and the protective cover 300.
[0021] Specifically, by sleeving and fixing the protective cover 300 outside the transformer, the protective cover 300 not only prevents the transformer from being knocked and damaged during the hoisting process of the transformer, but also can block impurities such as dust and rainwater from polluting the transformer during the transportation process of the transformer, which is beneficial to protecting the transformer in the transportation state. By driving the center of gravity of the oil conservator 720 to transfer from one end of the transformer to above the transformer through the center of gravity adjusting part 310, it is beneficial to maintaining the center of gravity stability during the hoisting process of the transformer and preventing the transformer from tilting and falling during hoisting. By fixing the arc-shaped plate 120 on the rear plate of the transportation vehicle, the transformer is installed on the arc-shaped plate 120 in a rolling manner through the carrier plate 210. The arc-shaped shape of the arc-shaped plate 120 facilitates the carrier plate 210 to automatically move to the balanced position with the transformer when the rear plate of the transportation vehicle slopes up and down, so that the transformer is always in a vertical arrangement state during the transportation process, effectively preventing the transformer from tilting and causing the transformer oil to flow out of the windings and electrical components, and at the same time preventing the windings from being deformed and damaged due to uneven stress during the tilting of the transformer, which is beneficial to improving the safety of transformer transportation.
[0022] Such as Figure 1 - Figure 3As shown, in this embodiment, connection seats are fixed to the bottoms of both ends of the cross beam 220. Rollers 221 are rotatably mounted at the bottoms of the connection seats. Two arc tracks 140 for the corresponding rollers 221 to roll on are fixed to the top surface of the first arc plate 120. Thus, after the first arc plate 120 tilts along with the transport vehicle, the carrier plate 210 can roll on the arc tracks 140 through the rollers 221, enabling the carrier plate 210 to be in a horizontal state at all times and the transformer to be in a vertically placed state at all times.
[0023] In this embodiment, the centers of the arc tracks 140, the first arc plate 120, and the second arc plate 130 are all located on the axis where the connecting column 360 is located. And the connection seats are arranged obliquely, and one end of the connection seat also points to the axis where the connecting column 360 is located. Thus, the carrier plate 210 can drive the transformer to rotate around the connecting column 360 as the axis on the first arc plate 120 to adjust the balance position.
[0024] As Figure 2 and Figure 3 shown, in this embodiment, the top surface of the support seat 110 is an arc surface, so that the support seat 110 can support and fix the first arc plate 120. An arc hole 131 is formed through the top surface of the second arc plate 130. The arc hole 131 facilitates the output end of the first hydraulic cylinder 231 to pass through the second arc plate 130, and when the carrier plate 210 moves, the output end of the first hydraulic cylinder 231 can slide at the position of the arc hole 131.
[0025] In this embodiment, the oil inlet and outlet pipelines of the first hydraulic cylinder 231 can be connected to the hydraulic system of the transport vehicle to realize synchronous control of the operation of the first hydraulic cylinder 231 by using the oil circuit system of the transport vehicle. The specific oil circuit connection control is the prior art and will not be elaborated here.
[0026] As Figure 6 shown, in this embodiment, since the second hydraulic cylinder 311 in this application is installed inside the protective cover 300, in order to save manufacturing costs, the second hydraulic cylinder 311 can be selected as a manually controlled hydraulic cylinder in the prior art to drive the center of gravity adjusting member 310 to work.
[0027] As Figure 5 and Figure 6 shown, in this embodiment, the fixing assembly 400 includes a U-shaped clamping plate 410 and a screw 420. The U-shaped clamping plate 410 is inserted between the carrier plate 210 and the U-shaped base 710. The U-shaped clamping plate 410 is fixedly installed on the carrier plate 210 by screwing with bolts. The screw 420 is screwed and fixed among the U-shaped base 710, the positioning column 320, and the cross beam 220.
[0028] In the above embodiment, in the initial state, referring to Figure 6, first hoist and sleeve the protective cover 300 outside the transformer. The positioning posts 320 at the bottom of the protective cover 300 are inserted into the ends of the U-shaped base 710. The user can use an external power tool to screw the screw rod 420 into the space between the positioning post 320 and the U-shaped base 710 to fix the protective cover 300 outside the transformer. It should be noted that the end of the screw rod 420 cannot pass through the positioning post 320 at this time, which facilitates the positioning post 320 to be inserted into the slot 222 of the cross beam 220 later.
[0029] In the above embodiment, refer to Figure 5 , after installing and fixing the protective cover 300 and the transformer, pass the two ropes 500 through the inside of the U-shaped base 710 respectively, and then use an external hoisting device to hoist the protective cover 300 and the transformer as a whole onto the carrier plate 210, so that the positioning post 320 is inserted into the slot 222 of the cross beam 220. Then rotate the screw rod 420 again to screw the screw rod 420 into the cross beam 220, so as to fix the U-shaped base 710, the positioning post 320 and the cross beam 220 together by using the screw rod 420. Then insert the U-shaped clamping plate 410 between the U-shaped base 710 and the carrier plate 210, and use bolts to fix the U-shaped clamping plate 410 and the carrier plate 210, so that the protective cover 300, the transformer and the moving part 200 are fixed as a whole.
[0030] As Figure 2 and Figure 3 shown, in this embodiment, the braking assembly 230 includes a hydraulic cylinder 231 embedded and fixed to the carrier plate 210. A friction plate 232 is detachably fixed to the output end of the hydraulic cylinder 231. An arc-shaped plate 130 is fixed to the top surface of the arc-shaped plate 120, and the output end of the hydraulic cylinder 231 penetrates through the arc-shaped plate 130.
[0031] In this embodiment, when it is necessary to move the carrier plate 210, the output end of the hydraulic cylinder 231 drives the friction plate 232 to move down to the position between the arc-shaped plate 120 and the arc-shaped plate 130. At this time, the friction plate 232 does not hinder the movement of the carrier plate 210. When it is necessary to fix the carrier plate 210 after moving to a certain position, the output end of the hydraulic cylinder 231 contracts to make the friction plate 232 move up to abut against the bottom surface of the arc-shaped plate 130, so as to fix the carrier plate 210 and the support part 100.
[0032] In the above embodiments, the friction plate 232 is arc-shaped, and the friction plate 232, the first arc-shaped plate 120, and the second arc-shaped plate 130 share the same center of circle, so that the friction plate 232 can adapt to the outer shape of the second arc-shaped plate 130 and abut against the outside of the second arc-shaped plate 130. A rubber sleeve is fixedly sleeved on the outside of the friction plate 232, and the rubber sleeve can make the friction plate 232 firmly abut against the second arc-shaped plate 130. Among them, the friction plate 232 is detachably fixed to the output end of the first hydraulic cylinder 231, and the friction plate 232 can also be detached. Then, the moving part 200 and the transformer as a whole are hoisted. After the carrier plate 210 is separated from the support part 100, the moving part 200 can move the position of the transformer on the cement floor at the installation position, which is convenient to move the installation position of the transformer on the ground.
[0033] As Figure 1 and Figure 4 shown, in this embodiment, two connecting columns 360 are fixed to the top of the protective cover 300. A V-shaped frame 600 is rotatably installed on the outside of the connecting column 360. Both ends of the V-shaped frame 600 are fixedly installed on the corresponding support seats 110 through bolts. A support shaft 610 is fixed at the corner position of the V-shaped frame 600, and a circular hole for the support shaft 610 to rotate is formed in the end face of the connecting column 360.
[0034] In this embodiment, after the protective cover 300, the transformer, and the moving part 200 are fixed together by the fixing component 400, the support shaft 610 on the V-shaped frame 600 is inserted into the circular hole of the connecting column 360, and the bottom of the V-shaped frame 600 is fixed to the support seat 110 with bolts, so that the support shaft 610 can stably rotate to support the protective cover 300, which is beneficial to improving the stability of the whole transformer transportation.
[0035] As Figure 7 shown, in this embodiment, notches are formed at the bottom of both sides of the protective cover 300, which are convenient for users to use power tools to screw the screw 420.
[0036] Embodiment 2. On the basis of Embodiment 1, in order to adjust the center of gravity of the oil conservator 720 to the middle position above the transformer, so that the hoisted transformer is not prone to tipping.
[0037] As Figure 5 、 Figure 6 and Figure 8As shown, in this embodiment, the center-of-gravity adjusting member 310 further includes a transmission column 312 fixed to the output end of the second hydraulic cylinder 311. The bottom end of the transmission column 312 is fixed to an arc-shaped clamping plate 313. One end of the arc-shaped clamping plate 313 is fixed with a baffle plate 314 for pushing the high- and low-voltage outgoing terminals 730. Two traction ropes 340 are fixed between the baffle plate 314 and the protective cover 300. The middle of the traction rope 340 is fixed to the high- and low-voltage outgoing terminals 730 at the corresponding position. One end inside the protective cover 300 is fixed with a support plate 350.
[0038] In this embodiment, after the protective cover 300 is sleeved on the outside of the transformer, the bolts fixing the oil conservator 720 to the transformer are removed, so that the oil conservator 720 can move on the transformer. The bolts fixing the multiple high- and low-voltage outgoing terminals 730 to the transformer are also removed, so that the high- and low-voltage outgoing terminals 730 can move on the transformer. Then, the output end of the second hydraulic cylinder 311 contracts, so that the arc-shaped clamping plate 313 drives the oil conservator 720 to move towards the middle position at the top of the transformer, so that the center of gravity of the oil conservator 720 can be transferred to the middle of the transformer, preventing the subsequent hoisting of the transformer from tilting. During the movement of the arc-shaped clamping plate 313, it will drive the baffle plate 314 to push the high- and low-voltage outgoing terminals 730 to move, facilitating the movement of the multiple high- and low-voltage outgoing terminals 730 to one side of the oil conservator 720, so that the oil conservator 720 and the high- and low-voltage outgoing terminals 730 are integrally arranged at the middle position at the top of the transformer.
[0039] In the above embodiment, when installing the transformer later, the output end of the second hydraulic cylinder 311 can be extended, so that the arc-shaped clamping plate 313 drives the oil conservator 720 back to the installation position. Since a traction rope 340 is connected between two adjacent high- and low-voltage outgoing terminals 730, when the arc-shaped clamping plate 313 drives the oil conservator 720 back to the installation position, the traction rope 340 is tensioned, and the multiple high- and low-voltage outgoing terminals 730 can also accurately return to the installation position. After the installation of the high- and low-voltage outgoing terminals 730 is completed, the traction rope 340 can be removed, or the multiple high- and low-voltage outgoing terminals 730 on the transformer can be directly removed and then installed later. The specific installation method is selected according to needs.
[0040] As Figure 7 and Figure 8 shown, in this embodiment, sliders 3121 are fixed on both sides of the transmission column 312. Two guide rails 370 that are slidably clamped with the sliders 3121 at the corresponding positions are fixed on the inner top surface of the protective cover 300, so that the transmission column 312 can stably move linearly.
[0041] As Figure 6 and Figure 8As shown, in this embodiment, a plurality of shaft rods 330 are detachably screwed and inserted between the two ends of the protective cover 300. Two adjacent shaft rods 330 are symmetrically distributed on both sides of the high- and low-voltage outgoing line ends 730, so that the high- and low-voltage outgoing line ends 730 can move stably in a directional manner during linear movement. A support plate 350 is fixed on one side inside the protective cover 300. The support plate 350 can support the moving high- and low-voltage outgoing line ends 730 to prevent the high- and low-voltage outgoing line ends 730 from falling off.
[0042] In the above embodiment, a runner is fixed at one end of the shaft rod 330, and a threaded groove is opened at the other end. Rotating the runner drives the threaded groove position of the shaft rod 330 to be screwed and fixed inside the protective cover 300. The runners of the plurality of shaft rods 330 are separately arranged at the two ends of the protective cover 300 to provide sufficient rotating space for rotating the runner.
[0043] As Figure 1 and Figure 7 shown, in this embodiment, transparent plates 380 are detachably installed and fixed on both sides of the protective cover 300. The transparent plates 380 facilitate viewing the working conditions of the center-of-gravity adjusting member 310 inside the protective cover 300. Among them, the transparent plates 380 can be made of acrylic material.
[0044] In this embodiment, the transparent plate 380 can be opened, and then the bolts of the transformer oil conservator 720 and the high- and low-voltage outgoing line ends 730 can be disassembled or installed from the installation position of the transparent plate 380 of the protective cover 300.
[0045] In the present invention, an electronic gyroscope, a component of the prior art, can be installed inside the carrier plate 210. The electronic gyroscope can detect whether the carrier plate 210 is placed horizontally. After detecting that the carrier plate 210 is placed horizontally, the center-of-gravity adjusting member 310 is stopped from driving the oil conservator 720 to move its position.
