Description

Technical Field

[0001] This invention relates to the field of heavy-duty mobile flatbed cart technology, specifically a heavy-duty mobile flatbed cart for ultra-high voltage transformers. Background Technology

[0002] Ultra-high voltage (UHV) transformers are electrical devices used to increase or decrease alternating current (AC) power. They are mainly used in the power generation, transmission, and distribution stages of power systems. UHV transformers are generally classified into three different sizes according to their structure: small dry-type transformers, medium-sized oil-immersed transformers, and large combined transformers.

[0003] Because ultra-high voltage transformers have complex and precise structures, they are very sensitive to vibration and impact during transportation, especially components such as converter transformer bushings. Excessive vibration and impact may damage the equipment. Moreover, ultra-high voltage transformers are the core equipment of ultra-high voltage converter stations, and their size and weight are extremely large. Therefore, flatcars with large load capacity and good stability are usually selected for transportation.

[0004] Currently, when transporting ultra-high voltage (UHV) transformers on flatcars, personnel typically need to operate overhead cranes to hoist each transformer onto the flatcar for placement. To ensure stability during transport, each UHV transformer must be evenly placed on top of the flatcar. This requires staff to repeatedly move the crane in different directions to evenly distribute the transformers across the flatcar. However, repeatedly adjusting the crane to move the transformers in different directions prolongs the time the transformers spend on the flatcar, reducing transport efficiency. Furthermore, manual placement of the transformers by overhead cranes cannot guarantee even distribution each time, leading to unstable transport of UHV transformers.

[0005] Therefore, it is necessary to design a heavy-duty mobile flatcar for ultra-high voltage transformers that features automatic uniform arrangement and high transportation efficiency. Summary of the Invention

[0006] The purpose of this invention is to provide a heavy-duty mobile flatcar for ultra-high voltage transformers to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a heavy-duty mobile flatbed for ultra-high voltage transformers, comprising a support plate, a support column fixedly connected to one side of the support plate, an alarm light for placing an overload alarm on the flatbed and triggering an alarm, an alarm camera for photographing the surface of the ultra-high voltage transformer fixedly connected to one side of the support column, four electric rollers for moving the flatbed evenly connected to the lower side of the support plate, a weight detection plate for measuring the load on the flatbed fixedly connected to the upper side of the support plate, a U-shaped slide rail fixedly connected to the upper side of the weight detection plate, guide grooves provided on both the inner and outer sides of the U-shaped slide rail, and ten arrangement mechanisms evenly provided on the upper side of the U-shaped slide rail for positioning the ultra-high voltage transformer and moving it in a staggered arrangement.

[0008] According to the above technical solution, the arrangement mechanism includes a transport block disposed on the upper side of the U-shaped slide rail. A first insert plate is fixedly connected to one side of the transport block, and two second insert plates are uniformly fixedly connected to the other side of the transport block. One side of each of the first and second insert plates is provided with an inclined surface. The transport block is provided with two first sliding cavities. The lower side of each first sliding cavity is provided with an avoidance groove. The interior of each first sliding cavity is provided with a clamping assembly for clamping and positioning the ultra-high voltage transformer. The lower side of the clamping assembly is provided with a transmission assembly. The lower side of the transmission assembly is provided with four sets of moving components for driving the transport block to move along the U-shaped slide rail.

[0009] According to the above technical solution, the moving component includes a rotating shaft rotatably connected inside the transport block. A torsion spring is provided on the lower outer side of the rotating shaft. One end of the torsion spring is fixedly connected to the rotating shaft, and the other end of the torsion spring is fixedly connected to the transport block. An L-shaped plate is fixedly connected to the upper outer side of the rotating shaft. A U-shaped plate is fixedly connected to the lower side of the L-shaped plate. A first motor is fixedly connected to the upper side of the U-shaped plate. The output end of the first motor passes through the U-shaped plate and is fixedly connected to a rotating wheel. The rotating wheel is connected to the U-shaped plate bearing and is slidably connected to the U-shaped slide rail.

[0010] According to the above technical solution, the transmission component includes a positive threaded column and a negative threaded column. Two positioning plates are fixedly connected inside the clearance groove. The negative threaded column is located on one side of one of the positioning plates, and the positive threaded column is located on one side of the other positioning plate. A turntable is fixedly connected to the other end of both the positive threaded column and the negative threaded column. The turntable is rotatably connected to the transport block. A second gear is fixedly connected between the two turntables. A first gear is meshed with the lower side of the second gear. A second motor is provided on one side of the first gear. The second motor is fixedly connected to the transport block, and its output end is fixedly connected to the first gear.

[0011] According to the above technical solution, the clamping assembly includes two sliders that are threaded to the outside of the positive thread post and the negative thread post, respectively. The sliders are slidably connected to the first sliding cavity. The sliders have a second sliding cavity inside. The second sliding cavity has two springs fixedly connected inside. The other end of the springs is fixedly connected to a clamping block. The clamping block has a clamping surface on one side and an inclined sliding surface and a sliding surface on the other side from top to bottom, respectively. The sliding surface is slidably connected to the second sliding cavity. The inclined surfaces of the first insert plate and the second insert plate have the same angle as the inclined sliding surface.

[0012] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0013] 1. During loading, ten arranging mechanisms slide simultaneously above the U-shaped slide rail, sequentially moving each arranging mechanism without an ultra-high voltage transformer under the operator's overhead crane. This allows operators to quickly place each ultra-high voltage transformer on the flatcar, effectively preventing the need for repeated crane adjustments to move the transformers in different directions and prolonging the time it takes for the transformers to be placed on the flatcar. Furthermore, the ten arranging mechanisms automatically shift and evenly distribute themselves above the U-shaped slide rail, ensuring uniform placement of each transformer. This effectively prevents uneven placement of the transformers on the flatcar, which could cause the flatcar's center of gravity to shift, leading to imbalance, tipping, or overturning. This achieves high efficiency and strong stability in transporting ultra-high voltage transformers.

[0014] 2. A camera is used to photograph the surface of the UHV transformer to be placed on the flatbed cart, and the image is compared with identification photos of UHV transformers of different structures in the internal database. The structure of the UHV transformer is identified in advance, and the type of UHV transformer is determined based on the obtained surface photos. This determines the size of the UHV transformer of this type, and then controls the combination of different numbers of arrangement mechanisms to match the clamping and support range suitable for this type of UHV transformer. This effectively prevents the phenomenon that excessively large UHV transformers cannot be transported under limited conditions, and achieves the effect of transporting a variety of UHV transformer types.

[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, please refer to Figure 1-9The present invention provides a technical solution: a heavy-duty mobile flatbed for ultra-high voltage transformers, comprising a support plate 1, a support column 2 fixedly connected to one side of the support plate 1, an alarm light 3 fixedly connected to the upper side of the support column 2 for triggering an alarm when the weight is placed above the flatbed, a camera 4 fixedly connected to one side of the support column 2 for taking pictures of the surface of the ultra-high voltage transformer, four electric rollers 7 evenly connected to the lower side of the support plate 1 for moving the flatbed, a weight detection plate 5 fixedly connected to the upper side of the support plate 1 for measuring the load on the flatbed, a U-shaped slide rail 6 fixedly connected to the upper side of the weight detection plate 5, guide grooves provided on both the inner and outer sides of the U-shaped slide rail 6, and ten arrangement mechanisms 8 evenly provided on the upper side of the U-shaped slide rail 6 for positioning the ultra-high voltage transformer and moving it in a tiered arrangement.

[0029] The following is a supplementary explanation based on the above structure: The weight detection plate 5 is used to detect the weight of the UHV transformers placed on top of the flatcar. To prevent overloading of the flatcar, which could lead to accelerated wear and frequent malfunctions of the flatcar components, when the weight detection plate 5 detects that the weight of all UHV transformers exceeds a previously preset weight value, the alarm light 3 turns red and an alarm sound is emitted. The arranging mechanism 8 also stops its limit and movement adjustments. The preset weight value is the maximum load capacity of the flatcar. Please refer to [link / reference]. Figure 1 In the initial state, in the four rows of U-shaped slide rails 6, two arrangement mechanisms 8 are evenly placed in each row of slide rails, and in one column of U-shaped slide rails 6, two arrangement mechanisms 8 are evenly placed in one column of slide rails.

[0030] Please see Figure 3 The arrangement mechanism 8 includes a transport block 81 located on the upper side of the U-shaped slide rail 6. The transport block 81 has two first sliding cavities 811 inside. The lower side of the first sliding cavity 811 has a clearance groove 812. The first sliding cavity 811 is equipped with a clamping component 84 for clamping and positioning the UHV transformer. The lower side of the clamping component 84 is equipped with a transmission component 85. The lower side of the transmission component 85 is equipped with four sets of moving components 86 for driving the transport block 81 to move along the U-shaped slide rail 6.

[0031] The following is a supplementary explanation based on the above structure: the upper part of the transport block 81 is used to place the ultra-high voltage transformer, so that the ultra-high voltage transformer can be moved and positioned by the moving component 86, and the clamping component 84 clamps and limits the ultra-high voltage transformer above the transport block 81.

[0032] Please see Figure 4The moving component 86 includes a rotating shaft 861 rotatably connected inside the transport block 81. A torsion spring 863 is provided on the lower outer side of the rotating shaft 861. One end of the torsion spring 863 is fixedly connected to the rotating shaft 861, and the other end of the torsion spring 863 is fixedly connected to the transport block 81. An L-shaped plate 862 is fixedly connected to the upper outer side of the rotating shaft 861. A U-shaped plate 866 is fixedly connected to the lower side of the L-shaped plate 862. A first motor 864 is fixedly connected to the upper side of the U-shaped plate 866. The output end of the first motor 864 passes through the U-shaped plate 866 and is fixedly connected to a rotating wheel 865. The rotating wheel 865 is connected to the U-shaped plate 866 by a bearing, and the rotating wheel 865 is slidably connected to the U-shaped slide rail 6.

[0033] The following is a supplementary explanation based on the above structure: the torsion spring 863 keeps the rotating wheel 865 pressed against the groove inside the U-shaped slide rail 6 by its elastic force. The rotation of the output end of the first motor 864 drives the rotating wheel 865 to rotate, thereby causing the rotating wheel 865 to drive the transport block 81 to slide along the groove of the U-shaped slide rail 6 through friction. When passing through the bend of the U-shaped slide rail 6, the groove located on the inner side of the U-shaped slide rail 6 compresses the rotating wheel 865, causing the two rotating wheels 865 on the inner side of the U-shaped slide rail 6 to rotate continuously along the rotating shaft 861, thereby adapting to the inner groove of the U-shaped slide rail 6. The groove on the side, and the rotating wheel 865 located outside the U-shaped slide rail 6, is continuously rotated along the rotating shaft 861 by the elastic force of the torsion spring 863, so as to adapt to the groove on the outside of the U-shaped slide rail 6. When all four rotating wheels 865 reach the straight track of the U-shaped slide rail 6, the four rotating wheels 865 rotate back to their original position along the rotating shaft 861. Compared with the traditional rectangular slide rail, the U-shaped slide rail 6 has a larger area distributed above the square flat car, and can install more arrangement mechanisms 8, thereby transporting more UHV transformers and improving the transportation efficiency of UHV transformers.

[0034] Please see Figure 5 The transmission assembly 85 includes a positive threaded post 852 and a negative threaded post 853. Two positioning plates 857 are fixedly connected inside the clearance groove 812. The negative threaded post 853 is located on one side of one of the positioning plates 857, and the positive threaded post 852 is located on one side of the other positioning plate 857. A turntable 851 is fixedly connected to the other end of both the positive threaded post 852 and the negative threaded post 853. The turntable 851 is rotatably connected to the transport block 81. A second gear 856 is fixedly connected between the two turntables 851. A first gear 855 is meshed on the lower side of the second gear 856. A second motor 854 is provided on one side of the first gear 855. The second motor 854 is fixedly connected to the transport block 81, and its output end is fixedly connected to the first gear 855.

[0035] The following is a supplementary explanation based on the above structure: the rotation of the output end of the second motor 854 is used to drive the first gear 855 to rotate, thereby driving the second gear 856 to rotate, and in turn driving the positive thread post 852 and the negative thread post 853 to rotate.

[0036] The clamping assembly 84 includes two sliders 843 that are threaded to the outside of the positive thread post 852 and the negative thread post 853, respectively, and the sliders 843 are slidably connected to the first sliding cavity 811.

[0037] The following is a supplementary explanation based on the above structure: when the positive thread post 852 and the negative thread post 853 rotate clockwise, the two sliders 843 are driven to slide and thus move closer to each other; when the positive thread post 852 and the negative thread post 853 rotate counterclockwise, the two sliders 843 are driven to slide and thus move away from each other.

[0038] When it is necessary to install an ultra-high voltage transformer on a flatcar, the operator uses a crane to place one of the ultra-high voltage transformers on top of the first transport block 81. At this time, the output of the second motor 854 of the first arrangement mechanism 8 drives the first gear 855 to rotate counterclockwise, thereby indirectly driving the positive thread column 852 and the negative thread column 853 to rotate clockwise. The two sliders 843 are driven to move and move closer to each other until the clamping blocks 841 above the two sliders 843 clamp the bottom of the ultra-high voltage transformer, limiting the movement of the ultra-high voltage transformer. The output of the second motor 854 stops moving. At this time, the outputs of the first motors 864 of all ten arrangement mechanisms 8 begin to rotate. The movement drives the rotating wheel 865 to rotate, causing the rotating wheel 865 to slide along the groove of the U-shaped slide rail 6 through friction. At this time, the first arrangement mechanism 8 moves to the position of the second arrangement mechanism 8, while the tenth arrangement mechanism 8 moves to the position of the first arrangement mechanism 8 to wait for the placement of the next UHV transformer. In this way, each arrangement mechanism 8 moves to the position it was waiting for before the next arrangement mechanism 8, so that each UHV transformer is placed on top of each arrangement mechanism 8 in sequence. When all arrangement mechanisms 8 have installed and limited the UHV transformer, the electric roller 7 rotates, driving the trolley to move to the area where unloading is required.

[0039] When the UHV transformer needs to be unloaded from above the flatcar, the output of the second motor 854 of the first arrangement mechanism 8 drives the first gear 855 to rotate clockwise, thereby indirectly driving the positive thread column 852 and the negative thread column 853 to rotate counterclockwise. The two sliders 843 are driven to move and move away from each other until the two sliders 843 are reset. The workers then use a crane to lift the UHV transformer above the first arrangement mechanism 8. After the UHV transformer above the first arrangement mechanism 8 is lifted out, the ten arrangement mechanisms 8 move and change positions in sequence, thereby bringing each UHV transformer to the workers' crane in turn. The workers then use the crane to lift down each UHV transformer that arrives in front of them in sequence. The steps of the ten arrangement mechanisms 8 moving and changing positions in sequence have been explained in the previous paragraph and will not be repeated here.

[0040] During loading, ten arranging mechanisms 8 slide simultaneously above the U-shaped slide rail 6, sequentially moving each arranging mechanism 8 without an ultra-high voltage transformer to the area beneath the operator's overhead crane. This allows the operator to quickly place each ultra-high voltage transformer on top of the flatcar, effectively preventing the need for repeated crane adjustments to move the transformers in different directions and prolonging the time the transformers spend on the flatcar. Furthermore, the ten arranging mechanisms 8 automatically shift and evenly distribute themselves above the U-shaped slide rail 6, ensuring uniform placement of each ultra-high voltage transformer. This effectively prevents uneven placement of the transformers on the flatcar, which could cause the flatcar's center of gravity to shift, leading to imbalance, tipping, or overturning. This achieves high efficiency and strong stability in transporting ultra-high voltage transformers.

[0041] Example 2: Ultra-high voltage (UHV) transformers are typically classified into three different sizes based on their structure: small dry-type transformers, medium-sized oil-immersed transformers, and large combined transformers. When the size of a UHV transformer is too large, its length is also excessive. A single arrangement mechanism 8 cannot limit or position UHV transformers whose size exceeds the clamping range. Consequently, excessively large UHV transformers can only be placed normally on flatcars by overhead cranes. During transportation, excessively large UHV transformers may shake or collide due to the lack of effective limiting, potentially causing damage to the internal structure of the transformer, such as winding deformation and insulation material damage, affecting its insulation performance and normal operation. Furthermore, without limiting, excessively large UHV transformers may shift or even overturn during transportation, damaging the equipment and endangering the safety of transportation personnel and the surrounding environment. Therefore, the following structure is designed to solve the above technical problems.

[0042] Please see Figure 3 A first insert plate 82 is fixedly connected to one side of the transport block 81, and two second insert plates 83 are evenly fixedly connected to the other side of the transport block 81. Both the first insert plate 82 and the second insert plate 83 have a slope on one side.

[0043] Please see Figures 6-8 The slider 843 has a second sliding cavity 844 inside. Two springs 842 are fixedly connected inside the second sliding cavity 844. The other end of the springs 842 is fixedly connected to a clamping block 841. One side of the clamping block 841 has a clamping surface, and the other side has an inclined sliding surface 8411 and a sliding surface 8412 from top to bottom, respectively. The sliding surface 8412 is slidably connected to the second sliding cavity 844. The inclined surfaces of the first insert plate 82 and the second insert plate 83 have the same angle as the inclined sliding surface 8411.

[0044] The following is a supplementary explanation based on the above structure: Camera 4 is used to take pictures of the surface of the UHV transformer that will be placed on the flatbed car. Camera 4 has a database and a judgment module inside. The database contains identification photos of UHV transformers with different structures. After camera 4 takes pictures of the surface of the UHV transformer, it will compare them with the identification photos of UHV transformers with different structures in the internal database, identify the structure of the UHV transformer in advance, and classify the UHV transformer into three different types of transformers based on the obtained UHV transformer surface pictures: small dry-type transformer, medium-sized oil-immersed transformer, and large combined transformer.

[0045] When the judgment module determines that this UHV transformer is a small dry-type transformer, since the small dry-type transformer has a relatively simple and compact structure and a small size, it is easy to install in places with limited space, such as the power distribution room or basement of a small building. Its volume and footprint are relatively small, so it is classified as small. Therefore, it is only necessary to place the small dry-type transformer on top of the single arrangement mechanism 8.

[0046] When the judgment module determines that this UHV transformer is a medium-sized oil-immersed transformer, since medium-sized oil-immersed transformers use an oil-immersed heat dissipation structure, they require a certain amount of oil tank to hold insulating oil to achieve cooling and insulation functions. Their overall size is larger than that of small dry-type transformers. Therefore, a single arrangement mechanism 8 cannot effectively limit the movement of a medium-sized oil-immersed transformer. At this time, among the ten arrangement mechanisms 8, the output terminals of the first motor 864 of two adjacent arrangement mechanisms 8 begin to rotate counterclockwise and clockwise respectively, driving the rotating wheels 865 of the two arrangement mechanisms 8 to rotate counterclockwise and clockwise respectively, thereby bringing the two closest arrangement mechanisms 8 closer together. Please refer to [link to relevant documentation]. Figure 7 Two second inserts 83 of one of the arrangement mechanisms 8 are inserted into the sides of the first insert 82 of another arrangement mechanism 8, while the first insert 82 of the other arrangement mechanism 8 is inserted into the middle of the two second inserts 83 of one of the arrangement mechanisms 8.

[0047] Until the inclined surface of the first insert plate 82 engages with the inclined sliding surface 8411 of the clamping block 841 of one of the arrangement mechanisms 8, and the inclined surface of the second insert plate 83 engages with the inclined sliding surface 8411 of the clamping block 841 of the other arrangement mechanism 8, the inclined sliding surfaces 8411 of the two clamping blocks 841 begin to be gradually squeezed, thereby driving the clamping block 841 to slide obliquely downward along the second sliding cavity 844. During the oblique downward sliding process, the clamping block 841 drives the spring 842 to be compressed until one side of the two transport blocks 81 is attached and the two springs 842 are fully compressed. At this time, the top surface of the clamping block 841 is flush with the top surface of the slider 843. The two clamping blocks 841 are pressed into the interior of the second sliding cavity 844 by the first insert plate 82 and the second insert plate 83 respectively. The two arrangement mechanisms 8 are merged, and the clamping range and support range are larger.

[0048] Workers use a crane to place the medium-sized oil-immersed transformer above the two combined arrangement mechanisms 8. The output terminals of the second motors 854 of the two arrangement mechanisms 8 rotate counterclockwise, thereby indirectly driving the positive thread column 852 and the negative thread column 853 to rotate clockwise. Each pair of sliders 843 is driven to move and move closer to each other, thereby clamping and limiting the medium-sized oil-immersed transformer. Since two of the sliders 843 are pressed into the interior of the second sliding cavity 844 by the first insert plate 82 and the second insert plate 83 respectively, they will not interfere with the normal placement of the medium-sized oil-immersed transformer. Furthermore, due to the restriction of the first insert plate 82 and the second insert plate 83, the sliders 843 pressed into the interior of the second sliding cavity 844 will not be pushed out again during the sliding process, causing damage to the bottom of the medium-sized oil-immersed transformer. During the arrangement of the medium-sized oil-immersed transformer, the two arrangement mechanisms 8 will not disintegrate.

[0049] When the judgment module determines that this UHV transformer is a large combined transformer, it is because it is often composed of multiple transformers, or its structure is designed with complex forms such as multiple windings and multiple taps to meet various complex power supply needs. Its size is enormous, its volume and footprint are very large, and it usually requires a dedicated large site for placement. Therefore, it is classified as large. Consequently, even the two arrangement mechanisms 8 are insufficient to clamp and limit the movement of a large combined transformer. Please refer to [link / reference]. Figure 8 At this time, in the four rows of slide rails of the U-shaped slide rail 6, the arrangement mechanism 8 in each row of slide rails approaches each other and merges. The steps of merging two arrangement mechanisms 8 have been explained above and will not be repeated here. At this time, the four-in-one arrangement mechanism 8 has a larger support range. The staff uses a crane to place the large combined transformer on top of the four-in-one arrangement mechanism 8. Every two sliders 843 approach each other, thereby clamping and limiting the large combined transformer. Usually, a flatcar can only hold one large combined transformer. Therefore, the four-in-one arrangement mechanism 8 does not need to be moved or arranged. Once the large combined transformer is limited, it can be transported by a flatcar.

[0050] Please see Figure 9 When an extra-large ultra-high voltage transformer is too long, and its length far exceeds that of a flatcar, two flatcars can be used simultaneously for transportation.

[0051] Camera 4 is used to photograph the surface of the UHV transformer that will be placed on the flatbed car, and compares the image with identification photos of UHV transformers of different structures in the internal database. The structure of the UHV transformer is identified in advance, and the type of UHV transformer is determined based on the obtained surface photos. This determines the size of the UHV transformer of this type, and then controls the combination of different numbers of arrangement mechanisms 8 to match the clamping and support range suitable for this type of UHV transformer. This effectively prevents the phenomenon that excessively large UHV transformers cannot be transported under limited conditions, and achieves the effect of transporting a variety of UHV transformer types.
